Sibling Rivalry - Chapter One

Warning: The following story describes events that are illegal, immoral, and just generally a very, very bad idea. Nothing in this story should be emulated. Nothing in it is a good idea. Nothing in it actually happened, either -- it's a work of pure fiction. If you are underage, easily offended by things that probably should offend you, or unable to differentiate between fantasy and reality, you should probably piss off right now.

Erin browsed through the pictures on her older brother Alex’s cell phone. They all looked fairly similar – blurry, poorly lit, and taken from the same angle; but they were damning enough. The phone’s low resolution and cheap plastic lens might not have gotten the finer details but it got more than enough to prove two things: the girl in the pictures was definitely Erin, and she was definitely performing oral sex on a man. Her long black hair may have obscured her face in some of the pictures, but there were quite a few that showed her elven face with an almost sadistic clarity.

She was overwhelmed by a number of emotions, none of which were positive. She was disgusted that her own brother would spy on her, enraged that he would blackmail her, and remorseful that she had let Steven talk her into going down on him in the first place. She was also extremely worried – she didn’t know exactly what Alex wanted, but she was fairly certain that she wouldn’t like it.

You can delete them if you like, Alex taunted. I’ve already made backups – there’s copies on my computer, e-mailed to myself, and on a thumb drive hidden somewhere outside of this household.

Erin wasn’t surprised. Alex might have been a cocky piece of shit, but he wasn’t an idiot – she knew he wouldn’t show her such juicy blackmail material without making copies first. Flipping his phone closed, she angrily tossed it back to him. She considered jumping at him and tearing his throat out with her teeth, but at six feet tall with a lean build she realized that he’d have little difficulty fighting her off. Two years older than her, Alex had always been bigger; and though they hadn’t fought physically since they were small she remembered how easily he had always been able to overpower her.

You’re a fucking pervert, she growled. What kind of a sick freak hides out in his own sister’s closet and spies on her? I’d really like you to explain to me why I shouldn’t tell mom and dad on you – this might be the final straw that gets you kicked out for good.

I’d be happy to explain, Alex grinned. Here’s what I’m thinking: You see, mom, I couldn’t find one of my shirts, and I thought it might have went back to Erin after you did the laundry last week. I was looking in her closet for it when I heard her enter her room with Steven. I figured that Erin remembered she’s not allowed to have boys in her room so they’d only be there for a minute, and I didn’t want to interrupt anything so I just sat quietly and waited until they left. Think that’ll work, Erin? Does it sound plausible enough?

And what, Erin sneered, while you were in my closet your phone just accidentally slipped and snapped off a couple of dozen of pictures? Yeah, that’s plausible. I honestly cannot understand how I could be related to someone so stupid.

I’ll admit it isn’t exactly bulletproof, Alex shrugged. To tell you the truth, I’m counting on them being a little distracted. Finding out that their son was doing bad shit won’t be much of a surprise to them, but their darling baby daughter? Shit, Erin, you’re supposed to be the good one; and yet here you are sucking the neighbor boy’s cock. They might not kick you out for that, but I’m betting you can kiss going away to college next year goodbye. Probably best for you to stay home until you learn how to act like a proper young lady, you know.

Unfortunately, Erin knew that he was right. Her parents were extremely conservative and militantly strict; the only reason they were willing to pay her tuition to an out-of-state school was because she had them convinced that she was a living saint. Even with their skewed view of her she had only just barely managed to convince them to agree; it wouldn’t take much for them to reverse their decision. Seeing their precious virginal daughter performing a disgusting sex act with a man in their own home would be more than enough to change their mind in a hurry. She knew that Alex would probably catch some hell for his role in taking the pictures, but that wouldn’t change the fact that she’d likely be spending the next couple of years in an all-female Catholic university. She didn’t want to admit it, but he had her beat.

I hate you so much, she growled. How could you do this to your own sister?

You’ve had it coming, he shrugged. You’ve always been their favorite, and I’m sick of it. You’re their little angel, I’m the demon-spawn that god sent to test them. I’m not telling you anything you don’t know, either – you know the situation, and you exploit it to your advantage. When they found that empty vodka bottle in the trash, it must have been Alex – precious little Erin would never touch alcohol. When their car was dented, it must have been mean old Alex, who never respects anyone’s property. I think it’s high time that you experienced what it feels like to be the black sheep of the family.

So that’s your plan? she demanded. You’re going to destroy your sister’s life just for some petty revenge? I know we’ve had our differences, Alex, and I know that I haven’t always been the best sister in the world to you, but I’m begging you – please don’t do this. Please, Alex? If you show them, it will literally ruin my entire life.

I’d prefer not to have to, he admitted. Well, that’s not entirely true – if it comes down to it, I’ll show them the pictures in a heartbeat and I won’t even feel the tiniest bit of guilt. Still, that’s plan B.

Then what’s plan A? she asked.

Simple, he laughed. Here’s the deal, Erin – I like getting my dick sucked. Unfortunately, a certain tattle-tale goody-two-shoes has created an environment where I can’t have a woman anywhere close to this house without mom and dad watching me like a hawk. It’s not the end of the world, of course – I can always go somewhere else for a blowjob – but just once, I’d like to fuck some bitch’s mouth in the comfort of my own bed.

Well what the fuck do you want me to do about it? she demanded. Mom and dad might trust me, but I’m not a miracle worker. You don’t honestly think I can convince them to look the other way so you can bring some skank into your room, do you?

It does seem pretty unlikely, he admitted. I mean they trust you, but there’re definitely limits. Hell, I bet if Jesus Christ himself were to appear in the flesh before them and demand that I be allowed to take girls into my room they’d probably just convert to a new religion, preferably one with a messiah who isn’t gullible enough to trust a piece of shit like me. Still, I can think of one cock- sucking little slut that I could take into my room without them so much as raising an eyebrow.

Erin racked her brain trying to figure out who he was talking about. She had seen some of the women that Alex dated. They were all raging sluts; not a single one of them would be permitted within a hundred yards of her parents’ home – even if her parents did trust Alex. Still, the way that he had said it implied that she should know who he was talking about. Noting the lecherous grin on his face, she began to realize in horror that he might have been talking about her.

You can’t be serious, she replied incredulously. Please, Alex, tell me that you’re not saying what it sounds like you’re saying. I’m your fucking sister, you sick fuck!

I don’t give a fuck, he shrugged. Just because you’re my sister doesn’t mean that you can’t suck cock – and I’ve got the pictures to prove it. It might not be ideal, but the convenience of being able to get a blowjob in my own home twice a day more than makes up for any taboo.

You really disgust me, she growled. Just thinking about this makes me want to vomit.

Then you’re thinking about it the wrong way, he laughed. This is actually a win-win situation. It took you what, like twenty minutes to get Steve off? You might be willing to let a guy fuck your mouth, but you don’t seem to know how the fuck to do it. I’ll give you a chance to practice – by the time you go to college you’ll be hands down the best little cock-sucker in the entire school. On the other hand, we can go to mom and dad. I’ll probably get a slap on the wrists for spying, but you? Missing out on the college of your choice is only the tip of the iceberg, Erin. They’ll remove your door and ground you until the day that you move out. You’ll be supervised at all times, only allowed out of the house to go to church – and you’ll be going to church an awful lot. Hell, I wouldn’t even be surprised if they had you fitted for a chastity belt.

But I’m your sister! Erin insisted. Doesn’t that mean anything to you?

Of course it does, Alex answered. It means that mom and dad will think nothing of leaving me alone with you. It means that if they happen to see you walking out of my room they’ll just assume that we were innocently talking. Mostly, though, it means that I have a chance to get my dicked sucked twice a day – once when I wake up, once before I go to sleep. You might be my little sister, but trust me – I won’t mind blasting my load down your dirty whore throat.

Erin had no idea what to do. Performing any sex act with her brother was repugnant to her, but she knew that he wasn’t kidding about how their parents would react if they were to see the pictures. Both of her options sucked, but she hoped that she might be able to change one of them. She couldn’t believe she was about to negotiate with her own brother over something so disgusting, but she didn’t see what choice she had.

You can’t cum in my mouth, she stated. I didn’t let Steven cum in my mouth, and I’m certainly not going to let my own brother. You have to warn me when you’re about to cum, and none of your cum is allowed to get anywhere near me. Also, this is a one-time thing – that’s very optimistic that you thought you might be able to pull it off twice a day, but that’s absolutely out of the question. You get one, and only one – and if you tell anyone about this, I swear to god I’ll murder you in your sleep. In exchange, I want all the pictures deleted – simply promising not to show them is not enough, I want them to cease to exist entirely.

Interesting offer, Alex laughed. Here’s my counter-proposal: twice a day, and I’ll cum wherever the fuck I want. Additionally, just to make sure you don’t change your mind, I’m going to fuck your mouth before I leave your room. If you have a problem with that, I suggest you start thinking up excuses for mom and dad. Maybe you could tell them that Steven’s pants malfunctioned, and then you tripped and fell on him, and then you had a twenty minute long seizure with your head in his crotch. They do seem to believe everything you say, so who knows – it might actually work.

Erin knew that he was mocking her – the pictures were explicit; there was no explanation that she could give her parents that they would be even remotely likely to believe. He had her beaten, and his unwillingness to negotiate in any way made it clear that he knew it. She was disgusted with herself for even considering it, but as hellish as what Alex was proposing it did seem moderately better than what she knew she’d have to deal with if her parents saw the pictures. She didn’t want to give in to his demands, but she needed time to come up with a plan.

I will never forgive you for this, she growled. Fine – you’re a sick fuck, but it’s not like I have a choice here. One in the morning, one at night, and no one – and I mean absolutely no one – ever hears about this or sees the pictures. Now get the fuck out of my room – just being in your presence nauseates me.

I’d be happy to, he laughed. Before I do, though, you need to do something for me first – the agreement is that I get a blowjob right now. If you want me gone, get on your little slut knees and get ready – I don’t plan to be gentle.

Erin took a deep breath. She was repulsed by what she was about to do, but she had no other options. Dropping to her knees, she tried her hardest not to think about what was happening. She reminded herself that in a few months she’d be three states away and out from under the watchful eyes of her parents, and once that happened she’d never have to see Alex again. She didn’t like the situation, but she knew it wouldn’t last forever.

Grinning as if he had just won the lottery, Alex approached her and dropped his pants. Already mostly erect, his penis jutted vulgarly towards Erin’s face. Erin was shocked – he was much larger than Steven was, and she wasn’t sure if she’d be able to fit it all in her mouth. She considered protesting, but thought better of it. She figured that he was arrogant enough without knowing that she thought his cock was intimidatingly large.

Placing his hand on top of Erin’s head, Alex slowly moved his hips towards her; bringing his erection closer and closer to her mouth. Erin struggled to turn her head away, but he managed to hold her firmly in place. With his cock inches away from her face, she could smell its musky scent. It wasn’t necessarily unpleasant – truth be told, she actually liked how he smelled on some primal level that she didn’t understand – but the fact that it was her own brother disgusted her. Utterly repulsed by everything about the situation, she clamped her jaw shut tightly.

So, first lesson, he stated. I’m a little amazed that I need to tell you this, but open your fucking mouth. I know you like to play up the whole innocent little girl act, but I find it difficult to believe that you need to be told to open your mouth so I can shove my cock in it.

I know that I need to open my mouth, she growled, offended that he would suggest she was that ignorant.

My bad, Alex laughed. I forgot that my own sister is such a pro cock- sucker. To be fair, giving you advice was probably pretty appropriate. I’ve never sucked a dick in my life, and I’m betting you’ve sucked dozens – if not hundreds – all while convincing everyone that you’re some chaste little princess.

Erin hated how he kept acting like she was some raging whore. The truth was that Steven had been the first and the only man that she had went down on, and she hadn’t even really wanted to do that. She suspected that Alex knew that and was only saying such things in order to humiliate her. She thought about arguing with him and letting him know that she absolutely was not the slut he kept making her out to be, but it didn’t seem like a possible goal. Swallowing her pride she reluctantly opened her mouth; telling herself that at least she’d soon have an excuse for not talking.

With her jaw open, Alex forced the tip of his cock into her waiting mouth. She was relieved to find that the size wasn’t as big of an issue as she had expected it would be – though she had to hold her mouth open slightly more than she had with Steven it wasn’t intolerably painful to do so. As she felt his shaft rubbing against her lips and tasted the head of his cock against her tongue she nearly gagged. He didn’t taste bad, but the idea that she was actually tasting her own brother’s private parts was a bit much for her to handle.

Careful there, bitch, Alex warned. Guys like it when you look like you’re having fun, and you look like you’re about to vomit. Try to smile – a slut like you ought to be fucking thrilled to be getting a dick in her mouth, even if it is her brother’s.

The criticism was a little more than Erin could tolerate. Jerking her head back, she pulled her mouth off of Alex’s cock. He pulled her hair hard, but she preferred that pain to having to listen to him telling her how she should be enjoying it.

It looks like I’m about to vomit? she demanded. I’ll clue you in on something, asshole – that’s because I am about to vomit. You might have found a bullshit way to force me to do this, but there’s absolutely no way in heaven or hell that you can force me to enjoy it. Like every other intelligent woman on this entire planet, I will never enjoy being anywhere close to your filthy little genitals.

That’s too bad, he laughed, clearly unimpressed with Erin’s tirade. If you really can’t bring yourself to even fake it, we’re going to be here for a long, long time. Here’s the deal, bitch – this blowjob doesn’t end until I cum. I don’t care if it takes six hours and your fucking jaw goes numb, I am not finished until I dump some sperm. If you want this to take longer, that’s fine – I’ve got nowhere to go in the immediate future.

It’s not my fault! she insisted. Try to understand this, Alex: I’m not disgusted because I’m trying to be disgusted; I’m disgusted because that’s how any normal, decent human being would feel in this exact situation. I honestly can’t help it!

Then learn to fake it, he growled. Because if we get to the point where I honestly believe that you’ll never get me off, I’m not going to let you off the hook. We hit that point and I’m just going to have to pick a different hole.

Erin didn’t take Alex’s most recent threat lightly. She was still a virgin, and though she wasn’t necessarily saving herself for marriage she certainly hadn’t been saving herself for Alex. She would sooner show her parents the pictures herself and accept the draconian punishment that would certainly result than actually allow her own brother to rob her of her virginity. Unfortunately, that wouldn’t exactly solve her problem.

Terrified, Erin immediately went back to work. She still found the act disgusting, but her sense of revulsion was overpowered by her fear of Alex making good on his threat. Repressing the loathing she felt for the entire situation, she began to feigning pleasurable moaning. She realized that any idiot could tell that she was faking her enjoyment, but she hoped that it would be enough to persuade Alex to show a little mercy.

A strange thing happened as Erin continued to bob her head back and forth. As time passed, Erin’s moans became more and more legitimate. She was still exaggerating them for Alex’s benefit, but the root source of them was no longer completely artificial. Horrified, she began to realize that there was a part of her that didn’t actually completely hate what was happening.

It wasn’t completely unexpected to her. Erin put a lot of effort into maintaining her good girl image, but she knew it was all a lie. The actions were legitimate – she really did avoid anything sexual – but it wasn’t like she actually didn’t have a sex drive. Secretly, Erin thought about sex quite a lot; and one of her favorite fantasies was being forced to orally pleasure a man. Still, she never fantasized about her own brother.

As time went by Erin found things shifting. Disgust was still present, but it was rapidly being overcome by her sense of lust. She tried to repress that, reminding herself that this was her goddamned brother that she was fellating, but her libido didn’t seem to care. She wasn’t happy about it, but she was legitimately turned on.

This might just be my imagination, Alex laughed, but it kind of sounds like you actually are getting off on this. I’m shocked, Erin – what happened to any decent human being would be disgusted? Did you misspeak, or is it just that you’re not quite as decent as you like to pretend to be?

You’re wrong, she insisted after pulling his dick out of her mouth. I hate this, I hate you, and I will absolutely never forgive you, you perverted freak.

That’s just sad, he shrugged, pulling Erin’s mouth back onto his cock. You should be more pragmatic, sis – you’ll be getting your face fucked by me at least twice a day, so you might as well enjoy it. Besides, it’s not like you’re fooling me. Everyone else might think that you’re a perfect little angel, but I’m your big brother and I know who you really are. I’m betting your little pussy is juicing up even now.

Erin absolutely despised the crass way that he talked about her, but she hated even more that he was right. Kneeling down on the floor of her room, she could feel her panties growing damp between her thighs. She didn’t want to think about what that meant, though, and she absolutely didn’t want to discuss it with Alex. Hoping to shut him up, she went back to sucking on him – as disgusting as that was, it was better than talking with her brother about how unbelievably turned on she was.

In desperate need of a way to distract herself from her shameful arousal, Erin challenged herself to go deeper with each stroke. As her brother’s cock penetrated into her throat she gagged painfully, but she preferred the simplicity of pain to having to think about why she was so turned on. Unfortunately, instead of distracting her from her lust the suffering seemed to add to it. Though she still had enough self-control to prevent herself, she wanted desperately to shove her hand down her skirt and masturbate.

On the plus side, Alex seemed to enjoy Erin’s suffering just as much as she secretly did. After a few minutes he began softly grunting with each thrust of her head. Erin wanted to find his obvious pleasure disgusting and gross, but it only added to her arousal – as much as she hated her brother at that moment, the fact that he was getting off on her actions was a major turn-on.

About ten minutes after she had begun Alex placed his hand on her head and pulled her in deep, choking her with his dick. Erin pulled her head back a little as Alex groaned loudly and his cock began to pulsate. Feeling her tongue being bathed in warm saltiness, Erin was horrified to realize that he was cumming. She yanked her head back roughly to get his cock out of his mouth, but not before accidentally swallowing some of his semen. Alex permitted her to pull her head off of his dick, but he didn’t let her go. Gripping her hair tightly he held her steady until he had finished his orgasm on her face.

Erin was utterly disgusted. She had never so much as touched a man’s semen before, and she hadn’t planned on changing that – especially with her own brother. She could still taste his cum in her mouth and she felt it slowly dripping down her face. In a show of defiance, she spit out as much as she could onto the floor. She hoped that Alex would be insulted by her open show of revulsion to the taste of his sperm, but he appeared to be more amused than anything else.

You really shouldn’t have done that, he chuckled.

I shouldn’t have done that?! Erin demanded. What the fuck did I say earlier? You can’t cum in my mouth or on my body – are you really so stupid that you forgot already?!

I didn’t forget, he shrugged. I just didn’t care. You can tell me where I’m allowed to cum all you like, but I’m under no obligation to obey. You, on the other hand, could stand to learn some obedience. Wasting my cum is a major no- no – you’ll either swallow it or wear it, but you absolutely don’t get to spit.

What the fuck are you going to do about it? she growled. And don’t waste your time bluffing – I know you too well to think that you’d show mom and dad the pictures over something like that. You show them the pictures and the deal is off entirely – I may be screwed, but you’ll lose your blowjobs.

You’re right, he admitted. But I can’t just let it slide – if I tolerate your bad behavior you’ll never learn. I often suspect that’s why you’re such a stuck-up cunt, by the way – you’ve never really been punished because you’ve always been able to pin the blame on me. That shit ends now.

Alex grabbed Erin by her hair and pulled her towards her bed. Taking a seat on the edge of the bed, he pulled her body over his lap. Erin was caught off-guard – though they frequently sparred verbally, they hadn’t fought physically in over a decade. By the time that she reacted and tried to get free it was too late; Alex had her over his lap with her arms pinned down behind her back.

Alex grabbed the hemline of Erin’s skirt as she thrashed about in a futile attempt to escape. Holding her steady with one arm, he pulled the skirt up over her back with the other, exposing the frightened girl’s panties. Erin was afraid of what he was about to do, but her greatest fear was that he’d notice how damp her panties were. Clenching her thighs tightly shut, she prayed that the white cotton fabric wouldn’t betray her secret. It seemed to work. Alex didn’t comment on her wetness, which Erin assumed meant that he probably hadn’t noticed – he wasn’t exactly the type to ignore it out of politeness.

With her skirt up and her arms pinned behind her back, Alex reached back and spanked Erin hard. Erin let out a frightened yelp as Alex spanked her again. As Alex continued to abuse her vulnerable ass Erin renewed her struggle with added vigor. She had never been spanked before, and she didn’t much care for it – it was painful, but more importantly it felt tremendously undignified. She was a grown woman; spanking seemed like something one would do to a wayward child.

Let me the fuck go! she demanded.

Eventually, he laughed as he continued the assault. You need to learn your place – hopefully this will help you to understand that it’s not acceptable to act like a spoiled little stuck-up bitch. Once I feel you’ve been adequately punished, you’ll apologize for your little temper tantrum and I’ll let you go.

Jesus Christ, Erin retorted, what drugs are you on? I will never apologize to you – you ought to be apologizing to me you fucking pervert.

You say that now, he shrugged, but I’m hoping that you change your mind before my hand gets sore. Even if you don’t, I can always just use a belt for a little while. You might have difficulty sitting down for a couple of days, but I’m sure I’ll be fine.

Erin was panicking. She realized that he had her completely at his mercy – he could spank her until the skin fell off of her ass and there wasn’t anything she could do about it. Still, she couldn’t bring herself to actually apologize to him. He was the one who behaved inappropriately – it was wrong, illegal, and disgusting for him to have cum anywhere near her. If he didn’t want her to spit it out, he shouldn’t have gotten it in her mouth.

Unfortunately, she knew that Alex wasn’t concerned with what was fair. She could make the argument that he was the one in the wrong in the most eloquent way possible, but it wouldn’t force him to let her go. As Alex continued to spank her ass hard, Erin felt her pride melting away and her willingness to say anything just to end the abuse increasing. It wasn’t just the pain, though. For reasons that made no sense to Erin, the spanking was only making her wetter. She felt that she needed to stop it before Alex noticed.

Okay, wait, she begged. I’ll say it. Please stop?

Alex let out a heavy sigh and temporarily stopped his assault. Resting his hand on her ass, he crudely gave it a squeeze, causing Erin to wince it pain. She wanted to tell him to stop – grabbing her ass was completely unacceptable – but she knew that it would probably be unwise to lecture him on morality at that point in time.

Well, sis? he mocked. I believe you have something to say to me?

I’m sorry, she choked out. Now take your hand off of my ass and let me the fuck go.

Unfortunately for Erin, Alex did not let her go. Chuckling quietly to himself, he raised his hand up and continued to spank her brutally. The pain was almost intolerable, Erin felt as though her ass was on fire. Despite her physical and emotional suffering, though, she was still more turned on than she could ever remember being.

I said what you told me to say! she protested. Please stop, I can’t take this anymore!

Not really, he critiqued. You were supposed to apologize for your temper tantrum, instead you simply spat out a generic I’m sorry, and you didn’t even sound sincere. I suspect you’re not sorry for the grievous sin of disrespecting my cum; you’re just sorry that you’re being punished. Maybe a little more spanking will help you to see the error of your ways. Let’s hope it doesn’t take long – my hand is growing tired and I don’t think you’ll prefer the belt.

Okay, I’m sorry! Erin cried. Please give me another chance?

I really shouldn’t, Alex sighed, pausing his assault and groping her ass again. You need to learn that your actions have consequences, and you can’t just whine until you get your way. Still, you’re my little sister, and I do love you, so I’m going to cut you some slack just this one time. I hope that you appreciate it, but more importantly I hope that you understand this mercy really is a one-time thing.

I understand, she insisted, tears streaming down her face. And I’m really, really grateful. I’m sincerely sorry for my temper tantrum. I should have swallowed your cum happily, and it was wrong for me to spit it out. Please forgive me? I promise I’ll never do it again.

I don’t know, he sighed, swatting her ass again. I just don’t think I buy it. If you were really sorry you’d probably beg me for a chance to lick my cum up off of the floor.

But that’s disgusting! Erin protested. You can’t actually expect me to do that, can you?

I most certainly can, he assured her, punctuating his words with hard slaps to her ass. Well, maybe not right away – but after a couple minutes of beating your ass with the belt, I’m pretty sure you’ll do anything that I suggest. It’s unfortunate that it has to come to that, but this is your decision.

Okay, wait, she begged. I can’t believe you’re making me do this, but okay. Alex – may I please lick your cum off of the floor? I’m begging you, nothing would make me happier.

I don’t know, he replied. Are you begging me because you want me to let you go, or are you begging me because you really want to do it? You did say it was disgusting and all, so I’m having a little difficulty believing you.

It’s because I really want to do it, she lied. I’m sorry that I said it was disgusting – I was lying. Please let me prove it to you, Alex?

Erin was disgusted with herself for the things that she had said, but it wasn’t like she had a choice. She was far more disgusted with herself for the fact that she had grown so wet – she was amazed that Alex hadn’t noticed yet but didn’t expect her luck to hold up for much longer. Fortunately, he seemed to accept her pleading. Releasing her arms he roughly shoved her off of his lap, causing her to land painfully on the floor.

Don’t make me regret showing you such mercy, he warned. I may not have you pinned down at the moment, but it wouldn’t be difficult to grab you and bend you over my knee again. Now, you claimed that you wanted to suck my cum off the floor – what’s stopping you?

Erin crawled up to her hands and knees. Her ass still hurt terribly, but that was the least of her problems. Looking down at the floor she saw the cum that she had spit out mixed with her own saliva, soaking into her carpet. Struggling not to vomit, she slowly leaned down above it and extended her tongue. She couldn’t believe what she was doing – drinking Alex’s cum was easily disgusting enough without licking it up off of the floor like some depraved whore. Still, she knew that she didn’t have a choice. Clenching her eyes shut she made contact with her tongue, struggling to repress her own nausea.

You’re testing my patience, Alex warned. You told me that you were desperate to lick my cum off of the floor, yet it looks as if you’re about to puke. Perhaps you need another spanking to really appreciate the honor that I’m permitting you by letting you eat my sperm.

God, please no! she whimpered. Alex, I swear to god, I’m trying as hard as I can. Please cut me some slack? You’re pushing me too hard!

I cut you slack when I gave you this chance, he growled as he stood up. Demanding more in so little time makes me feel like you’re not appreciating how gentle I’m being with you. Still, just because you’re my sister, I’m going to be kind. If you don’t want to eat my cum, you can wear it instead.

Before Erin had a chance to react Alex had pounced on her and again grabbed her by her hair. Erin was terrified, she feared that she was about to be spanked again and she didn’t think that she could handle that. To her surprise, though, instead of pulling her back to the bed Alex pressed down on her head, pressing her face into the small puddle of cum on the floor. Grinding her back and forth he forced her face into the cum, leaving it a sticky mess. Once he felt that he had mopped up enough of his slime with her face, he released her and stood back up.

I plan to go to sleep around midnight, he stated calmly. I’ll expect you in my room no later than 11:30. Please remember that I was exceedingly merciful with you this time – if you perform as poorly tonight I will make you regret it. Got that, bitch?

Yes, she sobbed. Can you please get the fuck out of my room now?

Of course, slut, he laughed, walking off.

Erin remained on the floor for a few minutes after he had left her room. Her face hurt from being rubbed in the carpet, her ass stung from the spanking. She was disgusted with herself for all of the things that she had done, and disgusted with her brother for his sadism. Most of all, though, she was more turned on than she had ever been in her life. The only thing preventing her from spending the next several hours masturbating furiously was what little pride she still had left, and she didn’t know how much longer that would hold out.

Chapter two is here.

Sibling Rivalry - Chapter Two

Warning: The following story describes events that are illegal, immoral, and just generally a very, very bad idea. Nothing in this story should be emulated. Nothing in it is a good idea. Nothing in it actually happened, either -- it's a work of pure fiction. If you are underage, easily offended by things that probably should offend you, or unable to differentiate between fantasy and reality, you should probably piss off right now.

This is chapter two of the story. If you haven't read chapter one yet, you should probably do that first.

Climbing to her feet, Erin looked into the body-length mirror that she had mounted over her closet door and surveyed the damage. Her hair was a mess; her face was covered in cum, saliva, and tears. She looked absolutely miserable.

Turning around, she hiked up her skirt and looked back over her shoulder into the mirror. Her ass didn’t look nearly as bad as she had expected. Going off of how it felt, she had expected it to be covered with bloody bruises, yet the skin was completely unbroken. It was covered with bright pink handprints, but didn’t appear to need medical attention. Just the same, it stung terribly.

Erin walked over to her bed and lied down on her back. This proved to be a mistake – the instant that her abused ass made contact with the mattress she winced in pain. Rolling over onto her front, she slipped a hand down her skirt and into her panties. She told herself she was just checking to see if she was as wet as she felt like she was, but she couldn’t quite convince herself that that was the only reason.

Reaching between her thighs, she experimentally felt the fabric of the crotch of her panties. Erin was disgusted to find out that she wasn’t just as wet as she thought she was, she was far wetter. Her panties were absolutely drenched; she almost suspected that she had lost control of her bladder without realizing it. Unfortunately, the fluids that drenched her were far too sticky to be urine – weeping in shame, she realized it was all her cum.

Disgusted with herself, Erin attempted to remove her hand from her panties. Unfortunately, while she was withdrawing it she accidentally brushed her finger up against her erect clit. Shockwaves ran up her spine – despite the fact that she had barely even touched it, she felt as if she were right on the edge of orgasm. She tried to tell herself that it was just a coincidence – completely unrelated to what her brother had just done to her – but she couldn’t seem to believe it.

Removing her hand from her panties, Erin began to weep quietly. She wanted to process what had just happened to her and come up with some kind of plan, but the only thing that she could think about was how much she wanted to shove her hand back down her panties and fuck herself silly. She hated what that said about her. She knew that of the countless acceptable ways to handle the stress of what her brother had just done to her, masturbation was absolutely not one of them. Unfortunately, no matter how hard she tried to distract herself her thoughts inevitably drifted back to how desperately she needed to cum.

Frustratingly, it wasn’t just her sense of decency preventing her from attaining some kind of satisfaction – there were logistical concerns as well. Erin had heard Alex retire to his own bedroom after he had left hers, and she occasionally heard him moving around through the paper-thin walls. It stood to reason that if she could hear him he could easily hear her as well, and she wasn’t about to let him hear her masturbate. If he did, she knew she’d never hear the end of it – he’d taunt her mercilessly every time they were alone, inferring that she was some kind of sex-crazy whore. Sadly, thinking about the things that he would say to her only exacerbated the problem – as she imagined the disgusting things that he might say she found herself growing even wetter.

Erin knew she had to deal with her problem. She couldn’t function in her current state; if she didn’t get some relief soon she felt as if she would explode. She wasn’t happy about what she knew she was going to do, but she could justify it to herself – if she didn’t do something soon she’d probably still be as frustrated and horny when 11:30 rolled around. Going back to Alex’s room as turned on as she was wasn’t just a bad idea; it was downright dangerous. She didn’t trust herself in that situation, much less Alex.

She considered her options. She pretended that doing absolutely nothing was an option, but she knew better – as much as she hated to accept it, the fact was that she was going to masturbate one way or the other. Masturbating in her own bed was completely out of the question – as frustrated as she was she knew that she couldn’t keep quiet enough to prevent her brother from hearing her through the walls, and putting on some loud music would almost certainly make him suspect something. She could head into the basement and do it there – Alex and Erin were on the third floor of the house, so he wouldn’t be able to hear her from that far away. The basement was risky, though. The door didn’t have a lock on it and her parents could come early – she had more than enough problems without her parents walking in on her while she fucked herself on the dirty concrete floor. Climbing out of bed, she headed for the bathroom. It was immediately across the hall from Alex, but the door locked and she could always turn on the shower to mask the noises she knew she’d be making. Besides, she could use a shower – she could still feel his disgusting cum drying on her face.

Erin shut the bathroom door behind her and locked it. After turning the shower on she quickly stripped out of her clothes. Folding them neatly and putting them on the counter next to the sink, she was repulsed with herself for how wet her panties were. The plain white cotton was absolutely soaked to the point of transparency; she couldn’t believe that she had made such a mess.

While she was waiting for the water to reach a comfortable temperature she reached down and softly touched her clit, just to see if she would react the same way that she had earlier. Unsurprisingly, the results were the same – sexual energy radiated out from her clit, her knees went weak, and she let out an involuntary moan. Afraid that she’d be unable to hold herself back if she went any further, she forced herself to hold off until she was inside the shower. It was difficult – her body screamed for satisfaction – but she managed.

Eventually the water reached an appropriate temperature and Erin climbed in. Bracing herself up against the wall, she bit down hard on her lip. She knew that silence wasn’t a realistic goal, but she needed to be somewhat quiet – at least quieter than the sound of the water hitting the porcelain tub that she was standing in. Focusing all of her energy on not crying out in carnal bliss, she timidly touched her clit again as warm water poured down over her.

The intensity was amazing. Despite the fact that Erin rarely came easily she already felt as though she were on the edge of orgasm. As her body shook in pleasure she felt her knees wobbling. Afraid that she might actually lose the strength to stand on her own, she laid down on her back. Her ass cried out in pain as it contacted the tub, but she no longer cared – at that moment the only thing that mattered to Erin was attaining her climax.

Lying on her back, Erin thrust her left hand into her mouth. She didn’t trust herself to keep quiet, and simply biting her lip wasn’t nearly enough. She hoped that she’d be able to gag herself forcefully. Besides, having an object thrust into her mouth reminded her of how she had gotten so turned on in the first place – she didn’t like admitting to herself that being forced to suck her brother’s cock had made her hot, but it was impossible for her to ignore.

Spreading her legs as wide as the tub would allow, Erin reached down with her right hand. She brushed up against her clit again, and received the same mind-shattering results. That wasn’t her goal, though. Lying down with her mouth gagged, Erin was tired of half measures. She pressed down hard on her clit with her thumb while curling a finger inside of herself.

That was all it took. Within seconds of penetrating herself with her finger Erin felt a powerful orgasm begin. Pressing down hard on her clit, she rode out the most intense orgasm of her entire life. She knew that she was still audible even with her fingers in her mouth, but she just didn’t care – nothing in the world mattered to her other than the immense sexual energy she was experiencing. Besides, even if she wasn’t silent she was still quiet enough that Alex wouldn’t hear her through the door and over the noise of the shower. At least, she hoped that was the case.

Erin’s orgasm lasted nearly a minute – far longer than what she was accustomed to. Even as it faded, she could still feel the aftershocks rippling through her body. She felt terribly disgusted with herself for behaving like such a depraved whore, but she still wanted more. She knew she’d hate herself for it later, but she wasn’t done yet.

Beginning to fuck herself in earnest, Erin rationalized her actions to herself. She figured that it was too late to come out of the situation with any kind of self-respect – she had, after all, just gotten so turned on by her brother orally raping her that she fucked herself to orgasm. Her opinion of herself was already as low as it could possibly be – fucking herself to another mind-shattering orgasm wasn’t likely to make it any worse. At least she would get it all out of her system. In a way, attaining satisfaction was the responsible thing to do – it would prevent her from losing control later that night when she had to suck her big brother’s cock again.

As she continued to fuck herself she felt her self-disgust fading. She still wasn’t happy about how she was behaving, but that became background noise. Her libido was again taking over control of her body; all she could think about was getting herself off again. She knew there’d be fallout to deal with later, but that could wait.

As Erin continued to fuck herself she found herself unconsciously pumping her left hand in and out of her mouth. At first she told herself that it was just coincidental – she was pumping her right hand in and out of her twat, so it was only natural that she’d do the same with her left. As her mind drifted to what had happened earlier, though, the flimsy excuse began to fall apart. She knew that she was emulating what it had felt like to have her brother fuck her mouth, and though she hated herself for how good it made her feel she couldn’t seem to make herself stop.

Rationalizing that if she was going to hate herself she might as well make it worth it, she closed her eyes and let her mind drift. She played out what had happened in her bedroom earlier in her head, though she made minor adjustments. Instead of fully clothed with her hands on Alex’s body, she was completely naked, using one hand to stroke his cock and the other to fuck herself. Pumping her two fingers in and out of herself roughly, she gave herself permission to continue the fantasy.

She thought about how her brother would react to seeing her fucking herself while blowing him. Not exactly the subtle type, he wouldn’t hesitate to hold back. He’d laugh at her, call her a disgusting whore, and do everything that he could to make her feel like the slut she was secretly beginning to believe she might actually be. He’d mock her for her inability to restrain herself, slap her around, and probably force herself to lick her own cum off of her fingers.

The idea of being forced to taste herself intrigued Erin. Though she consciously despised the idea of being forced to taste anyone’s cum – even her own – she liked the idea of being made to taste it anyway. Removing her hands from their respective holes, she switched them around. Pretending that Alex had ordered her to do so, she put her left hand back into her crotch and forced her right hand into her mouth, still dripping with her juices.

A part of her was horrified that she’d sink to such a low level, but that part of her was relatively quiet. As she pumped her hands in and out of herself she slathered her tongue between her fingers, tasting her own sex. She had always heard that pussy tasted like fish, but she didn’t taste anything like that. Sweet, and mildly fruity, she almost enjoyed her own flavor.

Pumping her hands quickly, Erin intentionally gagged herself. Though she knew it was only her fingers, in her mind it was Alex’s cock. The fantasy of having her face raped again was powerful; after only five more minutes she had reached her second orgasm.

Erin stayed in the shower for another hour, reaching orgasm six more times. By the time she had finished she was exhausted and sore; her clit was almost as sensitive as the bruised skin on her ass. She didn’t care, though. In fact, she would have stayed in the shower longer if not for the fear that Alex would realize something was up.

Climbing out of the shower, she toweled off and dressed herself. As the orgasmic high faded she found herself more and more disgusted with her behavior – she couldn’t believe that she had actually just masturbated while fantasizing about her own brother, especially in such a degrading way. Still, it was too late to take it back, and at least she wouldn’t be so sexually frustrated when 11:30 rolled around and she was forced to do it all over again. Besides, no one but herself would ever know what she had done.

Exiting the bathroom, Erin heard Alex moving around in his bedroom. She was a little nervous – though she had done her best to remain quiet she had hardly been silent. She wasn’t too worried though – she figured that if Alex had heard her, he’d have likely been waiting outside the bathroom eagerly anticipating an opportunity to taunt her for it. He certainly wasn’t the personality type to keep things quiet out of a desire to be avoid awkward situations.

Erin headed back to her bedroom and checked the clock. It was just after five and her parents would be home shortly. In a way that was a good thing – it was unlikely that Alex would try anything with them home. It had its drawbacks, though – even though she had just spent the last hour masturbating and her body was tired and sore, Erin still yearned for more. Once they returned home there would be nowhere in the house that she could get some satisfaction – they’d certainly notice if she took another shower in the middle of the evening.

Lying back down in bed, Erin stared at the clock. As disgusted as she was with herself, she was eagerly looked forward to when it read 11:30. She didn’t want to admit it, but she hoped that Alex would do more than just fuck her face when she climbed into his bed. She prayed that he would force her to do something – anything – that might result in another orgasm or two. Still, she reminded herself to be careful what she wished for – knowing Alex, she might just get it.

Chapter three is here.

Sibling Rivalry - Chapter Three

Warning: The following story describes events that are illegal, immoral, and just generally a very, very bad idea. Nothing in this story should be emulated. Nothing in it is a good idea. Nothing in it actually happened, either -- it's a work of pure fiction. If you are underage, easily offended by things that probably should offend you, or unable to differentiate between fantasy and reality, you should probably piss off right now.

This is chapter three of the story. If you haven't read chapter two yet, you should probably do that first.

Erin’s parents arrived home roughly fifteen minutes after her shower. She greeted them, but quickly retired back to her room. Her mind was still on sex, and she didn’t want to risk acting abnormally around them. She had enough problems as it was without jeopardizing her good girl image. Damage control was critical; she needed her parents to believe that there was absolutely nothing out of the ordinary going on.

Hiding out in her room, she counted down the minutes until 11:30. She repeatedly reminded herself that she was dreading it, but she just couldn’t seem to feel anything other than anxious anticipation and desire. She regretted that she hadn’t masturbated more when she had the chance – while her time in the shower had been immensely enjoyable, it hadn’t gotten it all out of her system. Sadly, it was too late to do anything about it – Alex was still in his room and her parents were downstairs; there was nowhere that she could go to relieve herself.

Her parents went to bed slightly after 10:00, as was normal behavior for them. Her parents were heavy sleepers, and with their bedroom on the second floor while Alex and Erin lived on the third it was unlikely that they’d be able to hear any noises that Erin or Alex might make. She wasn’t quite sure how she felt about that. On the one hand, it was nice knowing that her parents wouldn’t walk in on her and catch her sucking off her brother. On the other, she worried that there would be little incentive for Alex to keep things quiet.

Eventually 11:30 rolled around. Erin remained in bed for another few minutes. Though she was secretly looking forward to what might happen she didn’t want to appear overly eager and give her brother reason to believe that she was actually enjoying the abuse. As 11:32 flashed on her alarm clock, though, she heard Alex knocking on the shared wall that separated their bedrooms. Not wanting to provoke him into further sadism, she walked out of her bedroom and into his.

Alex was lying in his bed, already naked. He had obviously been thinking about what was about to happen – as he laid on his back he casually stroked his erect cock. Erin looked away instinctually – even after what had happened between them it still seemed completely inappropriate to see her own brother naked, especially in such a lewd pose. Alex seemed to find that funny. As she turned her head to the side, he began to softly chuckle.

I think it’s okay for you to see me naked, sis, he laughed. I have fucked your face, and all. Modesty doesn’t really make sense at this point.

It’s gross, she insisted, refusing to look. I’m not a pervert like you. Normal people don’t stare at their sibling’s naked body.

Now you’re just making me self-conscious, he sighed. There’s nothing gross about my body, Erin – lots of women seem to like it. I’m pretty sure you’re one of them, by the way – don’t think that I don’t notice you checking me out when you think I’m not paying attention. Go ahead and look, I know you want to and I really don’t mind.

Erin knew that he was right. Though she never really meant to ogle her brother’s body, she had caught herself sneaking glances from time to time. She always forced herself to look away when she realized what she was doing, and she assumed it was only natural – her brother had a nice body, and she was a healthy, sexually mature woman, and looking didn’t hurt anyone. It bothered her that he had noticed, though, and she didn’t feel like discussing it with him. In the hopes of ending the conversation, she turned her face back towards him and gave herself permission to look. Though she tried to stop herself, her eyes gravitated towards his erection.

See, that’s not so bad, Alex encouraged her. Unfortunately, I think I still feel self-conscious after your hurtful remarks. I’ll get over it in time, but I think you can do something to help that along. Lose your clothes, bitch – I don’t feel like being the only one here who is naked.

I can’t, she gasped. I’m sorry, Alex, but this is sick enough already. I can’t let you see me naked.

I’ve fucked your throat, he reminded her. You’ve tasted, drank, and worn my cum. A little nudity is the least of your problems. Anyway, I’m not asking. Strip naked on your own free will, or I’ll spank you until you’re begging me to let you take your clothes off. I’m good either way, but you should probably pick carefully – I won’t be gentle just because your ass still hurts from earlier.

You can’t spank me, she replied defiantly. Mom and dad will hear my screams. They might be heavy sleepers, but they’ll wake up quick if they hear their darling little daughter screaming in agony.

I’ll gag you first, he shrugged. And hopefully you’ll do your best to be quiet – if mom and dad were to walk in on me spanking you I might have to do something drastic to get their attention off of me, such as show them the pictures. Regardless, I’m done talking about this. Either lose your clothes, or I’m going straight to the belt.

Erin studied his face carefully. Sadly, it looked like he wasn’t bluffing – his facial expression and body language made it very clear that he’d make good on his threat without hesitation. Figuring that she’d end up naked one way or the other but she could at least spare herself a little further pain, Erin reluctantly stripped down to her bra and panties. Feeling her brothers eyes crawling over her body, she nervously folded one arm over her breasts and positioned the other over her crotch in a futile attempt to shield herself from his vision.

That’s not naked, he sighed. The parts of you that I’m actually interested in are covered – both by your underwear and your arms. You’re trying my patience here, Erin, which leads me to believe that you secretly want another spanking. If that’s the case, then everything is going to work out great – I’m about ten seconds off bending your disobedient ass over my knee and reminding you of your place. If I’m mistaken, though, you had better lose your clothes in a hurry.

Realizing that she was beaten, Erin stripped out of her underwear. Fully nude, she again folded her arms over her body to conceal her nakedness. She knew that Alex probably wouldn’t appreciate it, but she couldn’t help herself – she was uncomfortable enough with just being naked without his openly leering at her. Fortunately, while he didn’t seem grateful for the obstruction to his view, he didn’t seem angry enough to actually punish her for it. Raising his hand, he motioned for her to get into his bed with him.

I don’t know why you look so nervous, he stated as she approached. You have an awesome body, sis – at least I think that you do. I still can’t see the whole thing, but from what I can see I can tell you that you’re fucking hot. It almost feels wrong that you don’t show it off more – a hot piece of ass like you ought to be getting fucked as often as she can.

Erin wasn’t sure how to react to his compliment. Thanking him was out of the question, but she didn’t want to anger him by outright ignoring it. She gave him a polite nod to indicate that she had heard him and climbed into his bed. Reaching over, Alex grabbed her wrists and pulled them away from her body; exposing her full nudity. Erin crossed her legs tightly, but it didn’t seem to do anything to prevent him from staring.

Your nipples look just like I thought they would, he laughed as Erin struggled against him in a vain attempt to cover herself up. They look very sensitive. I wonder, do you play with them when you fuck yourself?

I don’t do that, she lied, embarrassed by the overtly sexual nature of his question.

Erin, come on, he laughed. We’ve lived together for all of our lives, and I’m sure you realize how little sound that wall blocks. You might be able to claim that you don’t masturbate if you had only done it a few times, but I think we both know that’s not how you are. I hear you fucking yourself at least once a day, and usually more – and that’s just what I notice. It’s like I told you earlier, bitch – everyone else might think that you’re some chaste little princess, but I know exactly how much of a slut you really are.

I am not a slut, she growled, and I don’t appreciate you eavesdropping on me, you fucking pervert. She knew that she had been behaving in a slutty way, but that wasn’t who she was and she didn’t care for Alex claiming otherwise.

Not a slut, Alex laughed. Good one, sis. Say, even with your legs crossed I couldn’t help but notice a lack of pubic hair. Tell me, Erin – why are you shaving your cunt if you’re not a slut? Is it because you like men to be able to see your cunt in graphic detail, or does the hair just get in the way when you’re fucking yourself?

Can we please just drop it? Erin asked, desperately wanting to change the conversation.

Someone’s eager to get to work, Alex laughed, releasing her arms. I’m not surprised – like I said, you I know that really are a slut. It must be torture for you to have to sit around talking when there’s a hard dick that you could get inside of you. As your big brother, it kills me to see you suffering like this, so go ahead. Suck my cock, you disgusting little whore.

Erin hated the way that he spoke to her, but she was eager to end the conversation about her perceived sluttiness any way that she could. Crawling down the bed, she laid down on her front with her head roughly level with Alex’s crotch, hoping that the position would prevent him from seeing too much of her naked body. As she brought her head into Alex’s crotch she restrained herself – though she was actually looking forward to what she was about to do, she didn’t want him to know. Feigning absolute disgust, she sucked his cock into her mouth and began to slowly bob her head.

Erin gradually built up speed; though she found that she couldn’t go quite as fast as she had the last time. Her throat still hurt from the blowjob that she gave Alex that afternoon and from her own self-abuse in the shower. Each time that she went too deep she gagged painfully, her throat protesting the rough treatment. She tried her best, but eventually accepted that she simply wouldn’t be able to be as aggressive as she had that afternoon.

Unfortunately, it didn’t seem like Alex was okay with her slacking off. He had been relatively passive and willing to let her do all the work that afternoon, but that was apparently no longer the case. Placing his hand on her head he guided her motions, forcing her to go far deeper and faster than she was comfortable with. It was tremendously painful, but he didn’t seem to care about the suffering that he was inflicting on her.

Despite the tremendous pain and discomfort that he was inflicted on her, Erin found herself reacting in precisely the same way that she had earlier. With each thrust she found herself getting more and more turned on; before long she could feel her own juices seeping down her thighs. She was deeply ashamed of her reaction, and her forced nudity made things even worse. As her clit began to throb in desire, she worried that it would be more difficult to hide her arousal from her brother.

You can fuck yourself, he laughed, briefly taking his hand off of her head. You obviously want to – don’t hold back on my account.

I do not, she insisted after pulling her head off of him. I’m not the pervert here.

Please, he laughed. I can smell your cunt from all the way up here. Don’t get me wrong, I don’t mind – it smells good and I’m actually wondering if it tastes good as well. Remember, Erin, I’m the one person who actually knows how often you fuck yourself. You’re not fooling me, and I’m not asking – finger yourself, slut. Show me what you were doing in the shower earlier.

Erin was mortified. She didn’t know if he had heard her in the shower or just guessed what she was doing based on how long she was in there, but the confident way that he accused her led her to think that he absolutely knew. She considered telling him that he was wrong, but that didn’t seem like a great idea – he’d probably want to argue with her, and she didn’t want to talk about it at all. Hoping to distract him, she forced her head back down his cock and began to suck him violently. It hurt like hell, but she needed him to forget about getting her to masturbate. Unfortunately, he didn’t seem interested in letting her ignore his demand.

I’m not going to warn you again, he sighed. I know how badly you want to fuck yourself, and as your brother it pains me to see you suffering like this. If you really can’t bring yourself to do it, I’ll do it for you. It’s your choice, bitch.

Erin groaned in despair. She hated the idea of masturbating in front of her brother. It was humiliating, disgusting, and she knew that he would take advantage and watch her like the pervert he was. Even more troubling was the fact that she knew she wouldn’t just be going through the motions – she knew that once she got going it would be blatantly obvious that she was enjoying Alex’s blackmail just as much as he was. Still, she figured she could at least prevent him from being the one that actually got her off. Reluctantly, she slid her hand beneath her body and between her legs.

She focused her willpower on the goal of staying silent as her finger made contact with her clit. Unfortunately, her body betrayed her – the instant she began to rub she found herself completely unable to mask her moans. Trying to focus on getting Alex off she hoped that his cock would muffle her moans of lust, though that didn’t seem too likely. Even though she was masturbating as timidly as she could, she couldn’t seem to keep quiet.

Your moaning seems to have improved, Alex commented. It looks like the key wasn’t learning how to fake it better – it was just putting you in a situation where you wouldn’t have to fake it. I think from now on all of my blowjobs are going to be like this. You’ll be fully nude, and you’ll fuck yourself for my amusement. Understood, bitch?

Erin absolutely didn’t want to agree to those terms, but she didn’t really have a choice. She knew that if she argued Alex would just force her to agree, and she really didn’t think that she could handle another spanking. Besides, with her libido taking over she thought the idea of having to masturbate while sucking her brother’s cock was extremely hot, even if she consciously knew that it was disgusting. Keeping his dick in her mouth, she timidly nodded to indicate that she understood.

You’re doing better, he continued, but I don’t want you getting lazy and there’s still room for improvement. Listening to you fuck yourself is incredibly hot, but I’ve heard it before countless times. I want to watch you getting off, I want to see your fingers slipping in and out of that hairless little fuck hole between your legs. Twist your hips so you’re lying on your side and keep your legs nice and open – I want to see everything, bitch.

Erin looked up at him, pleading with her eyes for him to reconsider. She was still uncomfortable with being seen naked at all, being seen naked and masturbating in such a vulnerable and exposed position seemed impossible. Unfortunately, the look that he shot back made it very clear that he was not open to negotiation and she’d regret it if she didn’t obey quickly. Hoping that he’d stop pushing if she just gave in, she reluctantly followed his orders.

Jesus Christ, slut, he laughed. I knew that you were wet, but you’re positively dripping! It looks like you could cum any second, so now is probably the time to let you know your next rule. You can fuck yourself to orgasm whenever you’re not around me, but when you’re sucking my cock you’re to ask permission before you cum. Now, I know that orgasms are important to you – if they weren’t I doubt that you’d fuck yourself so goddamned much. Be warned, though, I know exactly what you sound like when you cum and I will notice if you get off without my permission. Do that and I will punish you severely. I’m not talking about just a simple spanking, either – I will make sure that you regret it.

Erin groaned again in despair. Though she wasn’t exactly right about to cum, she wasn’t far off either. She absolutely despised the idea of needing her brother’s permission to cum, but a part of her found it deeply erotic. She realized that it didn’t really matter what she thought, though – Alex didn’t seem interested in debate or compromise.

After a couple of minutes Erin felt her orgasm drawing dangerously close. She slowed her masturbation, but it didn’t seem to help – she was far too close to calm down. Looking up at him she begged him with her eyes to grant permission, but he simply ignored it. She hated the idea of actually having to verbally ask her own brother to let her cum, but she didn’t want to find out what horrific thing he’d do to her if she broke his newest sick rule.

Can I please cum? she forced out, hating herself for saying the words.

After just two minutes? he laughed. Goddamn, sis – you really are a slut. I’ve listened to you fucking yourself countless times, and I don’t think I’ve ever heard you get off this quickly – you must really love sucking your brother’s dick.

Erin was deeply ashamed, but she couldn’t think of an argument. She wanted to tell herself that her high state of arousal had nothing to do with the things that he was forcing her to do, but she just couldn’t believe it. The fact that he knew was humiliating, but it wasn’t her biggest problem. Her biggest problem was that she needed to cum, and he still hadn’t given permission. She really didn’t have time to discuss the matter with him.

Okay, I’m a slut, she whimpered. Can I please have permission now? I can’t hold off much longer.

I don’t think it would be appropriate, he sighed. As your brother, I feel compelled to guard your honor – and cumming this quickly is just undignified. I’m not completely merciless, though. You can stop fucking yourself for a few minutes, just so you can calm down. Keep your legs open, but take your hand off of your cunt.

Erin groaned loudly. As humiliated as she was, the pain of being denied an orgasm when she was that turned on was tremendous. As she followed his directions her pussy screamed at her, aching with desire for satisfaction. Unfortunately, as much as she wanted to cum she was far too terrified of what he might if she disobeyed him.

Alex reached forward, grabbed her by her wrist, and began to pull it up to his face. Erin was mortified – her hand was still dripping with her cum, and she didn’t want him taking a closer look. She resisted, but he was far too strong for her. As she watched in horror and disgust he brought her hand to his face and licked her fingers, tasting her juices.

You taste even better than you smell, he commented as she went back to sucking him in a futile attempt to distract herself. In fact, you taste so good that I might not mind sucking that little whore pussy of yours. I bet you’d like that, wouldn’t you?

Keeping his prick in her mouth, Erin shook her head to indicate that she wouldn’t. The idea seemed so disgusting to her – she hated him knowing how wet she was and was still disgusted by the fact that he now knew exactly what her pussy tasted like, letting him go down on her was out of the question. Unfortunately, as much as Erin’s conscious mind despised the idea, her cunt was enthralled. She was desperate for her orgasm, and willing to put up with pretty much any indignity in order to get it.

Aww, that’s too bad, Alex laughed, releasing her hand. I’m a little hurt, but that’s okay. I’ll ask again later, just in case you change your mind. I have a feeling that you will.

He was right and Erin knew it. Her need for an orgasm was intense; it had taken a serious effort on her part just to decline his offer the first time. She realized that she’d almost certainly allow him to taste her directly the next time, but she figured she could at least save a little dignity by putting it off.

Erin continued to suck Alex, straining to keep her legs open. It wasn’t just the shame that made it difficult, though. She was so aroused; having her legs open but being forbidden from actually doing anything about it was pure torture. Unfortunately, while keeping her hands off of her clit had stopped her from reaching orgasm, being forced to suck Alex’s cock prevented her from calming down in any serious way.

Okay, I think that’s a long enough break, Alex announced after a few minutes. You look so desperate; it would be cruel for me to prevent you from fucking your whore pussy for even a second longer. Remember, though – I absolutely have not given you permission to cum. You can play with yourself all you like, but if you finish you will regret it.

Erin didn’t need any further encouragement. She hated that she would have to ask him for permission to cum when the time came, but at that moment the only thing that she cared about was getting some kind of stimulation to her aching groin. Plunging her hand back between her thighs she masturbated aggressively, making up for lost time.

After having been denied her last orgasm Erin was even more aroused than she had been the time before. After only a minute she felt herself already on the edge of a powerful orgasm. Realizing that it would be nearly impossible for her to hold it off she wrenched her head off of Alex’s cock and prayed that he’d be a little more merciful than he had the time before.

May I please cum? she whimpered.

Jesus fucking Christ, he laughed. It hasn’t even been a minute, you fucking slut. I’m sorry, but I just can’t let you cum this quickly – it’s just not dignified.

Please Alex! she begged. I need this! If I don’t cum I’m going to explode!

Poor slut, he sighed. I’ll tell you what – I won’t let you fuck yourself to orgasm. You’ve done that more than enough today, and you really ought to be ashamed. I’m not entirely unsympathetic, though, so here’s what I’ll offer. Spin around and bring that tight little twat up to my face so I can taste you while you suck me. If you can manage to cum from having your brother’s tongue in your cunt, you have my permission to do so. Of course, you’ll have to go the rest of your life remembering that you actually got off from having your brother tongue-fuck you, but that’s your problem.

Erin suspected that Alex thought she would have to think about it for a while, but he was completely mistaken. She knew how disgusting what he was proposing was, but she didn’t care – she’d have been willing to do just about anything just to get some satisfaction. Spinning around quickly, she hiked one knee over Alex’s shoulder and straddled his face. She knew she’d regret giving in so easily later, but delaying her orgasm any longer just wasn’t an option.

Alex seemed a little shocked that she had complied so easily, but he held up his end of the deal just the same. Reaching forward he placed his hands on Erin’s ass and groped it crudely. Erin winced in pain as he roughly squeezed her sore ass, but the pain did nothing to turn her off. Running his hands up her waist, he pulled her back towards his face until she could feel his breath against her sensitive flesh. As Erin continued to force her mouth up and down Alex’s cock, she felt his tongue finally making contact.

An initial pang of disgust shot through Erin, realizing that her brother was actually licking her pussy. It felt so corrupt and wrong; she couldn’t believe that she had sunk so low. That pang faded quickly, though, as his talented tongue went to work. It didn’t take long. Erin was already on edge, and her brother was disturbingly good at what he was doing. After only a minute of feeling his tongue flicking against her clit and exploring her hole, Erin’s orgasm began.

Forcing her head down on his cock, she hoped that it might muffle some of the noises that she knew she’d be making. As waves of pleasure coursed throughout her body she thrust her ass back, grinding it against her brother’s head. She felt terribly slutty behaving like that, but she knew it was far too late to pretend that she wasn’t getting off on what she was doing. Besides, the humiliation of acting like that with her own brother was a major turn-on; it seemed to only magnify the intensity of her orgasm.

As Erin rode out her own orgasm, Alex’s began. With his cock almost entirely in her mouth, Erin felt it spurting inside of her as her mouth quickly filled with the taste of his semen. Still high on the bliss of her own climax, she greedily swallowed it all down. She didn’t want to be punished again, but that wasn’t the only reason. She didn’t want to admit it, but being forced to drink her brother’s cum seemed tremendously hot – even if it was disgusting at the same time.

The siblings stayed in that position until their orgasm eventually ended nearly half a minute later. Erin laid on top of her brother, completely exhausted and panting for air. She could still taste his cum in her mouth, and she was aware that his face was still in her naked crotch, but she just didn’t care. She simply didn’t have the energy to move herself, even as she felt Alex playfully flicking his tongue against her cunt while grabbing her ass.

I don’t want you getting used to this, he explained, sounding just as exhausted as Erin was. I don’t mind sucking your cunt, but I don’t want you getting the wrong idea. You’re my bitch – you come here to get me off, not to exchange oral. In the future I’ll expect you to get yourself off while I watch. I might occasionally take pity on my poor little slut sister and throw her a bone, but don’t start thinking that I’m obligated to help make you cum. Is that understood?

It is, she panted. She didn’t like acknowledging that she’d be masturbating for his enjoyment when she sucked him off in the future, but she didn’t have the energy to argue the point.

Good slut, he laughed. You should probably get back to your room now and get some sleep. I expect you back here first thing in the morning to suck my cock again, and I want you to be well-rested so that you can do a good job.

Still in a dreamlike state, Erin did as he asked. Crawling off of him, she grabbed her clothes off of the floor and headed back into her room. She was so dazed that she didn’t even bother to dress herself before heading into the hallway – it seemed pointless anyway, her room was right next door. Climbing into her own bed, Erin’s mind raced. She had attained the sexual satisfaction that she had been craving all day, but she knew that it was only a matter of time before it returned.

Chapter four is here.

Sibling Rivalry - Chapter Four

Warning: The following story describes events that are illegal, immoral, and just generally a very, very bad idea. Nothing in this story should be emulated. Nothing in it is a good idea. Nothing in it actually happened, either -- it's a work of pure fiction. If you are underage, easily offended by things that probably should offend you, or unable to differentiate between fantasy and reality, you should probably piss off right now.

This is chapter four of the story. If you haven't read chapter three yet, you should probably do that first.

It had been two weeks since Alex initially began blackmailing Erin, and not much had changed. She’d go down on him twice a day, once in the morning and once at night. She was still deeply disgusted with herself, but she was gradually adjusting. Though she hated the idea of what she was doing, it still managed to turn her on more than anything she had ever experienced. She was masturbating much more than she ever had in her life, and she knew it wasn’t a coincidence.

Alex was mostly fair with her, but relentlessly strict. If she did everything that he said immediately and without argument he’d usually stick to the most basic interpretation of their agreement, but if she messed up in even the slightest way he’d come up with sadistically humiliating ways to punish her. Spanking was just the tip of the iceberg – he had made her wear his cum on her face overnight, forced her to repeatedly masturbate up to the point of orgasm and then stop abruptly, taste her own cum, and accept his finger up her ass. Erin hated how creative he was – he rarely seemed to punish her in the same way twice. Mostly, though, she hated how much she enjoyed the punishments on a level that she didn’t want to think about. She wasn’t proud of it, but she knew that she had intentionally messed up more than once just to provoke him into abusing her further.

It was Friday, and Erin was extremely nervous. Her parents were driving up to New Hampshire to attend a friend’s wedding, and they were planning to leave Erin and Alex on their own. They had left their children home alone in the past, but that was before Alex had the blackmail material. With them gone, she worried that Alex’s sadism would climb to new heights. She could imagine being forced to stay naked the entire weekend for no other reason than to humiliate her sexually. She hated how much she secretly hoped that that would be the case.

By 6:00 her parents were ready to go. They had loaded their bags for the weekend into their car, and were about to head out. As they said goodbye to their children Erin’s mother reminded them that Erin was in charge while they were gone. She didn’t like that – in the past she could control Alex with threats of ratting him out when they got home, but that wasn’t going to work anymore. Being the older sibling, Alex had always resented having Erin in charge; she was a little worried that he’d find a way to punish her for their mother’s comment as soon as he could.

Surprisingly, Alex did nothing of the sort. Instead of tearing her clothes off and slapping her around the instant that their parents were gone he simply retired to his room as if nothing was out of the ordinary. He fucked her face on Friday night and Saturday morning, but didn’t seem to take advantage of having their parents gone at all. Erin was confused – her brother was an opportunist and it really wasn’t like him to pass up a chance to degrade her. She considered making sure that he was feeling okay, but decided not to. She was having enough trouble just knowing that she wanted him to do something to her, clueing him in to her secret desires would only make things worse.

Erin heard the doorbell ring on Saturday afternoon. Leaving her room, she went downstairs to see who it was. Alex was already there; when she reached the first floor she saw him letting Jon into their home.

Jon was not permitted in the house. In fact, Alex wasn’t even allowed to associate with Jon, though their parents’ attempt to enforce that rule had never been all too effective. Much like Alex, Jon had a reputation as a bad seed. He drank, used drugs, and had frequently ditched school back when he was in high school with Alex. Unlike Alex, though, Jon was not their parents’ son and they saw little reason to tolerate his negative influence. Erin had only met Jon a few times, though she didn’t much care for him. Something about him just made her nervous.

Still, she wasn’t too worried. She had expected to spend the weekend being sexually abused; if all Alex was going to do was have a friend over without his parents’ permission she figured she could handle that easily. Heading back to her room, she began to feel cautiously optimistic – if Jon was crashing at their place for the night it might mean that she’d finally get a night off. She didn’t think that her brother would risk letting his friends know that he was forcing his own sister to go down on him. Alex might have had a reputation for being many negative things, but she didn’t think he’d want to add depraved incestuous pervert to that list.

Erin laid down in her bed and relaxed. She was bored, but she enjoyed the rare moment of peace. A part of her was actually a little disappointed that Alex would rather get drunk with one of his loser friends than play with her, but she forced herself not to think about that too much. Besides, she really needed some time off to recover and process already.

Around 11:45 she heard a knock on her wall. Assuming that one of them had just bumped up against the wall accidentally, she decided to ignore it. A few seconds later the knock repeated, which she also ignored – she couldn’t imagine that her brother would actually want his friends to know what he had been doing to her. A few seconds later, though, she heard her brother shouting through the wall for her attention.

Get the fuck over here you lazy bitch, he yelled from his room.

Erin didn’t know what to make of it. She couldn’t imagine that he actually expected her to perform her nightly ritual when he had company, but she had no idea why else he’d want her in his room. Still, he didn’t sound very patient, and she didn’t want him remembering her disobedience once Jon was gone and she was entirely at his mercy. Crawling out of her bed, she headed over to his room to see what he wanted.

Took your slow ass long enough, he growled as she entered. Have you forgotten about our arrangement or something, you dumb whore?

I don’t know what you’re talking about, she replied nervously as she glanced in Jon’s direction.

I fucking knew you were full of shit, Jon laughed. Like your sister would ever suck anyone’s dick, especially yours – she’s such a fucking prude she makes nuns look dirty by comparison.

Erin was beginning to panic. Apparently Alex had told Jon all about their arrangement, and she absolutely wasn’t okay with that. She knew he’d be pissed off at her for lying, but the fact that Jon clearly didn’t believe him gave her hope. Hoping to kill the rumor before it got started, she decided to roll with her lie.

What the fuck did you tell him you sick freak? she demanded, feigning outrage.

Alex didn’t answer verbally. He simply let out a sigh and headed towards his computer. He moved the mouse around to turn off the screensaver, causing the screen to light up. After navigating through a few folders he double clicked an icon. A few seconds later an image popped up on the screen. Erin recognized it instantly as one of the ones that Alex had taken from her closet of her going down on Steven. She was mortified, but at least it didn’t directly controvert her story.

That’s not you, pervert, she insisted. Seriously, just look – that’s Steven from next door, you look nothing like him. Also, you promised not to show anyone you asshole.

I clicked the wrong icon, he shrugged. You’re sure you want to force me to prove this, right? Last chance to back down and tell him the truth.

Erin looked at Alex, begging him with her eyes to drop it. She silently mouthed the word please, but Alex appeared to be completely unmoved. Shaking his head, he closed the picture of her with Steven and double clicked a different icon. After a few seconds his computer’s video player opened.

Erin was horrified. The video was shot from the shelf right above Alex’s bed, where she realized he must have hidden a camera. She recognized her brother’s naked body stretched out on the bed, though his face was out of frame. As the video continued to play, she watched in terror and shame as her own naked body came into the frame and laid down next to Alex on her bed.

Panicking, Erin lunged towards the computer. The part that had played already was damning enough; she absolutely didn’t want Jon seeing the disgusting things that she knew she’d be doing on screen next. Unfortunately, Alex had anticipated her reaction. He grabbed her and easily restrained her before she was able to get anywhere close to the computer.

Turn it off! she begged. Please Alex, for the love of god just turn it off already!

See, I would, he laughed as he held her down. Unfortunately, I can’t. Jon here thinks that I’m a liar – largely because of the lie that you just told. You know how much I despise it when it’s your word against mine and people just automatically assume that I’m the one who’s full of shit, but this time I have a chance to defend my honor. I’m sorry that this is embarrassing to you, but you did bring it on yourself by lying in the first place.

Okay, I admit it! she cried as she watched herself begin to masturbate on screen. I lied, Jon – I’ve been sucking my brother’s cock twice a day. I don’t know what else he’s told you, but it’s all probably true – he’s done disgusting, rancid things to me and I’ve let him. Can you please turn it off now, Alex? I told the truth and I’m really sorry that I lied, but please just turn it off?

That wasn’t so hard, now was it? Alex laughed.

Releasing his grip on the girl, Alex turned around and paused the video. Erin wished that he had closed the player instead of pausing it – the frame that he had frozen on showed her inserting his cock into her mouth while fingering herself in painful clarity – but she was happy that Jon wouldn’t see whatever depraved actions came next in the video at least. She knew she wasn’t quite out of the woods yet, though – Jon knew far too much and she was worried he might tell others what he had seen.

Make him promise to tell no one, she demanded. Make him swear that he saw absolutely nothing.

How would you propose I do that? Alex laughed. Should I just wave my magic wand in his face and order it? He’s a grown man, Erin – all I can do is ask nicely and hope for the best. Observe – Jon, could you do me a favor and not tell anyone about this?

Fuck that noise, Jon sneered. Remember back in 10th grade when your stuck-up bitch of a sister told the principal that we were smoking weed behind the gym? Stupid bitch could have just kept her mouth shut and everyone would be happy, but instead she fucked us both over hardcore. I’m telling everyone I know – see how she likes being ratted out.

Alex, please! she begged. If he talks it’s going to get back to mom and dad, and if that happens then your blackmail material is completely useless. I know this is my fault and I’m really sorry, but you need to help me! If you won’t do it for me, do it for the blowjobs?

Hey, I’m sympathetic, he shrugged. And I definitely don’t want to lose the thing we’ve got going, but it’s like I said – he’s a grown man, I can’t force him to keep silent. If you’re really that interested in keeping him from talking, though, maybe you should offer him something in exchange. He might be convinced to keep this all to himself if you sucked his cock, you know.

Erin hated the idea of trading sexual favors for discretion, but she didn’t know what else she could do. She realized she had done worse – Jon at least wasn’t a blood relative, so while it was tremendously sleazy it wasn’t incest like it was with Alex. Swallowing her pride, she turned to face Jon.

Promise me that you won’t tell anyone, she offered, and I’ll suck your cock.

I don’t know, he sighed. I’m still kind of pissed off about that bullshit you pulled in school, to be honest. Fucking your face would be fun, but destroying your pristine holier-than-thou reputation might still be worth it.

Look, I’m sorry for what I did to you! she begged. Please forgive me? Wouldn’t you rather get revenge by raping my mouth than gossiping about me anyway?

She is pretty good, Alex chirped in. I’m not going to interfere with your decision or anything, but I’ve been training this little slut on how to suck cock for weeks. Trust me man, it’s worth it.

Erin was a little offended by Alex’s endorsement – she was embarrassed enough about her situation without having him telling others how good she was. Still, if it meant killing the rumors that Jon might circulate she was willing to put up with it. Dropping down to her knees, she looked up at Jon timidly, begging him with her eyes to cut her a little slack.

Whatever, he sighed. She had better be as good as you say – I don’t cum easily.

Erin might not have been looking forward to sucking off her brother’s friend, but she was eager to get the deal done with so she could move on with her life. Crawling up to him, she reached up to undo his zipper so that she could get started. Before she was able to remove his pants, though, Alex grabbed her by the hair and threw her back. Landing painfully on her back, she looked up at him in confusion.

I just said you know how to suck cock, he explained, and you’re already making me look like a liar. You should be showing off how well I have your slut ass trained, yet you’re still fully dressed. Fix that, slut – and don’t make me correct you again.

Erin let out a heavy sigh and began to disrobe. She hated the way that both Jon and Alex stared at her body, but she realized they had seen it before – Alex in real life and Jon in the video. After stripping out of her bra and panties she again approached Jon and knelt down before him. While her brother watched on judgmentally, she undid his fly and pulled his pants and boxers down to his knees.

Jon was already semi-erect. Grabbing his dick in her hand, she licked the shaft a few times. Jon reacted quickly – before long he was mostly hard. Keeping her hand around his cock, she inserted it into his mouth.

His cock tasted strongly of sweat. He obviously hadn’t showered recently, and Erin could taste the difference. As she experienced what it was like to go down on a man with poorer hygiene than Alex she found herself strangely grateful – Alex might have been a complete bastard, but he typically cleaned himself up before fucking her mouth. Still, the salty taste wasn’t enough to make things impossible, and she really did need to prevent him from telling anyone what he had seen.

Please don’t make me remind you what you should be doing, Alex warned. I know damned well that you know better than to let your hand just hang there.

Erin groaned in shame. She knew that he was telling her to masturbate, but she really didn’t want to. Masturbating while her brother and his friend watched felt insanely slutty to her, but that wasn’t her biggest concern. Being forced to suck cock was still a major turn-on for Erin and she could already feel herself juicing up – she worried that if she encouraged it she’d quickly lose control of herself. Still, she didn’t want to piss Alex off any further. Reluctantly, she reached down with her hand and began to timidly play with her clit.

Alex watched in silence for a few minutes before grabbing the bottle of hand lotion from his desk and approaching. Erin was terrified – he had only picked up the lotion once before, and that was to lubricate his finger before he stuck it up her ass. Being anally fingered was traumatizing enough without a virtual stranger there to watch it; she knew she had to do something to stop him. Putting Jon’s blowjob on hold for a second, she turned to beg her brother for mercy.

Alex, please don’t, she pleaded. I’m doing what you told me to; please don’t do what I think you’re about to do.

You were late, he sighed. When you finally bothered to stop by you lied in an attempt to defame me. You were dressed inappropriately, and I just don’t like your general attitude. You need to be punished or you’ll never learn to improve.

I’m sorry! she exclaimed. I know that I fucked up, and I’m really very, very sorry about that. I accept that you need to punish me, but can you wait until we’re alone?

There’s that attitude again, he lamented, shaking his head in disapproval. Here’s a novel idea, sis – how about you focus on sucking cock and let me worry about punishing you. God knows it’s what you’re best at.

Erin didn’t know what to do. She hated the idea of having her ass fingered while Jon watched, but arguing with Alex only seemed to make things worse. Turning her attention back to Jon, she did as Alex had suggested and resumed sucking his cock. She was worried, but she hoped that her show of obedience would convince Alex to show her a little mercy for once.

Unfortunately, Alex didn’t seem to be feeling very merciful at all. Ignoring Erin’s demonstration of fealty, he sat down on the floor next to her. Erin watched out of the corner of her eye as he pumped a small amount of lotion onto his finger and rubbed it in. She wanted desperately to make him stop, but she had no idea how to.

Lift that ass into the air, he ordered. Prove to me that you’re done misbehaving for the night by showing Jon how much you enjoy getting your slutty little asshole finger-fucked.

Erin did as he asked, raising her ass into the air and bending over a little to continue sucking Jon. She hoped that it was a test, and once Alex had demonstrated that he could make her do it he’d stop. She realized that seemed pretty unlikely, but she clung to the hope just the same.

Picking up the lotion again, Alex squirted a bit more directly into Erin’s asshole. She winced a little – the cool fluid didn’t hurt, but she wasn’t prepared for the sensation. As she groaned in shame and despair, she felt his finger pressing up against her anus. The lotion was an excellent lubricant – he had little difficulty sliding it in.

Erin did her best to focus on Jon instead of what her brother was doing, but it wasn’t easy. Alex wasn’t content to just stick his finger up her ass and leave it there; he obviously planned to actually fuck her with it. Moving slowly at first he began to pump his finger in and out of her ass, gradually building speed. The sensation was intense and impossible to ignore.

With Alex fingering her ass and Jon fucking her mouth, Erin stopped masturbating. It wasn’t that she didn’t want to continue – Alex’s assault on her back door had only turned her on further – but she didn’t trust herself. She knew that if she kept playing with her cunt she’d be begging Alex for permission to cum in minutes, and she really didn’t want to have to do that while Jon was still around. She was also afraid that both Jon and Alex would notice how much more she seemed to enjoy masturbating while having her asshole fingered. Fortunately, Alex either didn’t notice that she stopped or didn’t care.

After a few more minutes Alex slipped another finger into her asshole. Erin groaned loudly in protest, but she didn’t dare stop sucking Jon’s dick to complain. She knew it would only make Alex angry at her; it wasn’t like she’d be able to convince him to stop anyway. Besides, though she hated how undignified the situation was she enjoyed the sensation of being stretched out. She began to worry that even without masturbating she might end up having to ask Alex for permission to cum just because of the things he was doing to her ass.

Alex continued to fuck her with two fingers until he was able to pump them quickly without causing Erin any pain. Removing his hand, he squirted more lotion onto it before pumping more directly onto Erin’s asshole. As Erin watched nervously out of the corner of her eye, Alex forced three fingers into her ass.

Up until that point the assault hadn’t hurt physically. Though it was tremendously humiliating, Alex had gone relatively slowly so as to avoid pain. Three fingers was a different story, though – even though Alex went slowly, Erin still felt pain as her asshole stretched to accommodate him. She whimpered in pain, but she was able to manage.

Alex began to gradually build speed, just as he had done before. As her body stretched to accommodate him Erin felt the pain dissipating. She wasn’t sure if that was a good thing. She liked the fact that it didn’t hurt as much, but without the pain it was difficult for her to ignore how good it felt. She didn’t want to be the kind of girl who liked it in the ass – especially not in such a despicable situation. She was glad that she had stopped masturbating – if she was still playing with herself she’d have almost certainly had to ask Alex for permission to cum by then.

You disappoint me, Erin, Alex sighed.

What did I do? Erin asked nervously. She thought she was doing what Alex wanted, and had no idea why he sounded angry with her.

The fact that you even have to ask that only proves that I’ve been too easy on you, he answered. We’ve been through this before, bitch – when you suck cock, you fuck yourself.

I’m sorry! she pleaded. I didn’t know that I had to while you were fingering me!

I have difficulty believing that, he shrugged, though it doesn’t really matter. The fact is that this is only another in a long string of failures on your part tonight, and it isn’t even the most severe. You’ve been sucking his cock for nearly ten minutes now, and he still doesn’t look like he’s anywhere near orgasm. I told him that you knew how to suck cock, and you’re making me look like a liar. Additionally, I’m growing tired of waiting – I had hoped to be fucking your mouth right now, yet my sense of hospitality prevents me from doing so until you finish off our guest.

I’m sorry! she cried. Please don’t be mad at me Alex, I’m doing the best that I can!

Maybe you are, maybe you aren’t, he replied coldly. It doesn’t really matter, though – clearly your best just isn’t good enough. You need to be punished, and I’m tired of waiting for your mouth to free up. Fortunately, I can think of a solution that addresses both of these issues. You have three holes, after all – waiting to use the one that you prefer simply doesn’t making sense.

Erin realized that he was talking about actually fucking her. She was consciously terrified – giving her brother her virginity was absolutely not okay. At the same time, though, she could feel her cunt yearning for his attention. She knew that she had to try to stop him, but a part of her secretly hoped that she would fail.

You can’t! she protested. Alex, I’m still a virgin – even you couldn’t be so cruel as to steal your own sister’s virginity!

How confident are you of that? he laughed. You seem to have mistaken my kindness for obligation, sis. I’ve been willing to tolerate your bullshit about saving your virginity in the past, but that was before I had to wait in line. I’m going to be fucking one of your holes in the next minute, and it doesn’t look like your mouth is going to be available. I’m sorry that this didn’t work out for you, but you really have no one but yourself to blame.

Erin groaned, absolutely disgusted with herself for what she was about to suggest. She didn’t want to engage in anal sex – the mere idea of taking it up the ass struck her as disgusting and wrong. At the same time, though, getting fucked in the ass was marginally better than giving her virginity to her own brother. Besides, he had already prepared her for it.

You could fuck me ass instead, she whimpered quietly.

What’s that, sis? Alex laughed. If you’ve got a suggestion you’re going to have to speak up. Speak clearly and tell me what you want, and I might be willing to consider it.

Erin understood what he wanted. He wasn’t going to let her just suggest that he fuck her in the ass as an alternative, he wanted her to act like she desperately wanted it. The idea was deeply humiliating – begging her brother to fuck her in the ass was despicable, especially in front of his friend. Still, it seemed better than having her first time be with her own brother. Swallowing her pride, she realized she didn’t really have a choice.

I said, she began, you could fuck my ass instead, Alex. You know how much I’ve always wanted you to fuck me up the ass, and you’re right – it doesn’t make sense for you to have to wait in line when I have other holes available. Please, Alex, take me anal virginity instead – I’d be ever so grateful.

Erin’s face went bright red as Alex and Jon laughed at her self-inflicted humiliation. She was utterly disgusted with herself, but she knew that she had no choice if she wanted to remain a virgin. On the bright side, it looked like Alex was convinced – he pulled his fingers out of her ass, dropped his pants, and began to rub more lotion onto his erect cock. Erin was grateful for that, at least. If he had forced her to beg any further, she might have just let him take her virginity.

Kneeling down beside her, Alex pressed the head of his cock against Erin’s virgin asshole. She was worried – he was much, much thicker than three fingers and she wasn’t sure if she’d be able to take it all. As he pressed in she groaned in pain, feeling her asshole stretching to its very limits. The pain was intense, but in a way it was desirable – she welcomed any distraction that might prevent her from thinking about the fact that she was getting fucked up the ass by her own brother. Hoping to further distract herself, she went back to sucking Jon’s cock as she felt Alex slowly forcing deeper into her.

I really hope you aren’t going to need another reminder about what you ought to be doing with your hand, he warned. Just because I’m already fucking you in your tight little slut asshole doesn’t mean that I can’t punish you in other ways, too.

Groaning in pain and humiliation, Erin reached back and began to masturbate as he had ordered. She felt like the biggest whore in the world, with a dick in her mouth and asshole and her fingers inside her pussy. The pain of Alex stretching her out was still at the forefront of her mind, but the humiliation was a close second. The way that Alex and Jon laughed at her degradation wasn’t helping, either.

Eventually, Alex managed to get his entire cock inside of her. Holding it still for a moment, he gave Erin some time to adjust to his girth. It was effective – she rapidly felt the pain melting away. Unfortunately, that just made it easier for her to think about what was really happening. Feeling her fingers brush up against her brother’s balls, she realized that she really was getting fucked in the ass. She again attempted to distract herself by pouring her energy into sucking Jon, but it was futile.

After a few seconds Alex decided that she had had enough time to adjust. Moving extremely slowly, he began to pump his cock in and out of her ass. Though it still hurt, Erin barely noticed the pain. Between the humiliation, the taboo, and the stimulation to all of her orifices at the same time she felt an orgasm rapidly building. She tried to push it off – she felt like a big enough whore as it was without cumming from getting fucked in her ass by her own brother. Still, she knew she wouldn’t be able to hold off for very long.

Ignoring her mental anguish, Alex began to build speed. After a few minutes he was fucking her at a brisk pace. With the pain almost entirely gone, Erin began to realize that she actually enjoyed getting fucked in the ass. She knew a big part of it was her secret desire to be humiliated and used, but even without that she loved the way that it felt. She didn’t like what that said about her, but she couldn’t pretend that it wasn’t the case.

Reaching down, Jon began to play with her nipples. He was rough and abusive, but at that point that was exactly what Erin wanted. She knew that she couldn’t hold herself off from cumming for much longer. Asking for permission from her own brother in front of Jon would be humiliating, but she figured that it wouldn’t be the most disgusting thing that he had seen her do that night.

Alex, she moaned, may I please cum?

What do you think, buddy? he asked Jon. Think I should let this bitch cum?

Erin didn’t like the fact that Alex was asking Jon’s opinion on something that didn’t even concern him, but she knew that there was nothing that she could do about it. Looking up at him, she begged him with her eyes while stroking his cock with her hand. She despised being at the mercy of someone who she looked down on, but she couldn’t hold herself back any longer and didn’t want to find out what Alex would do if she came without permission.

I guess, he laughed. Let the little whore cum.

With permission granted, Erin let herself go and came explosively. Alex’s dick in her ass seemed to multiply the force of her orgasm; it was violently loud even by her standards. Jon sat back and watched her cum with great interest, but Alex seemed to ignore her orgasm entirely; focusing only on plowing her ass. Erin didn’t care – at that moment the only thing on her mind was how good it felt to cum.

Alex fucked her ass for another ten minutes before cumming. Grunting loudly, he thrust his dick into her as deep as he could and flooded her with his semen. Erin was surprised to realize that she actually liked that – she didn’t know why, but the idea of being filled with her brother’s cum was a huge turn-on for her. Although she had grown to grudgingly enjoy swallowing his cum, she found that she much preferred having it shot directly into her.

Alex pulled out of his sister and pulled his pants back up. Walking back to his bed, he lied down and relaxed. With her brother’s cock no longer in her asshole Erin felt disturbingly empty, but she didn’t dare say anything. She figured Jon and Alex had enough evidence that she was a slut without her begging Jon to fuck her in the asshole.

Fortunately, she didn’t need to ask. Jon let her continue to suck his dick for another minute after Alex had cum in her ass before growing bored of her mouth. Grabbing her hair, he pulled her off of him and forced her to lie on her back. Excited to about the prospect of getting her ass fucked again, Erin spread her legs wide to provide him access. She knew it would only give them more reason to believe that she really was a slut, but at that point it didn’t seem like it would make a difference.

After rubbing some lotion on his cock, Jon knelt down between Erin’s legs and pressed the head of his cock against her clit, causing her to moan in pleasure. Slowly moving it down her pussy and towards his ass, he briefly pushed it between her lips. That terrified Erin – although a growing part of her just wanted to be fucked for real already, she wasn’t willing to lose her virginity just yet. Fortunately, Jon continued to slide his cock down until it was pressing into her asshole. Staring her dead in the eyes, he forcefully pressed it in.

Hooking her ankles up over his shoulders, he began to fuck her hard. Fortunately, Erin was still loose from her experience with her brother only minutes earlier so the pain minimal and was easily manageable. This was fortunate, as Jon didn’t seem interested in going gentle. He clearly still resented the things that Erin had done to him in the past and seemed to want to use anal sex as a way to get revenge. He was rough, forceful, and utterly disrespectful. Unfortunately for him, that was exactly how Erin secretly wanted it by that point.

The blowjob had gotten him close, so he only managed to fuck her ass for five minutes before cumming himself. Just as her brother had done, he thrust himself in as deep as he could before releasing his sperm inside her. After dumping the contents of his balls in her, he spit in her face, pulled out, and quickly dressed himself.

Erin laid naked on her brother’s floor, her legs still spread wide and cum slowly dripping out of her asshole. She realized how she must have looked, but it didn’t seem to matter anymore – she couldn’t think of anything that could make either Jon or Alex view her as a bigger slut anyway. Her ass, mouth, clit, and breasts were extremely sore, but she didn’t really mind. Despite all the pain and humiliation she was feeling, she just wanted to cum again. She had been extremely close when Jon unceremoniously finished with her.

So, Alex stated, breaking the silence. Here’s how this will work. If you tell anyone what happened here, Jon, it’ll probably get back to my parents – which means that I’ll have to find a new cum dumpster. That’s a dick move on its own, but it’s also strategically a bad idea on your part. I’m not a greedy guy, and I’m willing to share her as long as her holes belong to me. Keep your mouth shut, and I don’t mind if you occasionally fuck my sister in her mouth or ass. Stay out of her cunt, though – I have something special planned for that.

Erin didn’t know how to feel. She was glad that her brother was finally standing up for her, though she wished that he could have found a way to do it without whoring her out to his scumbag friend. It did seem like it would work, though – Jon was unlikely to tell anyone and risk fucking up a good thing. Mostly, though, she worried about what special plans her brother had in mind. She wanted to ask, but she knew the odds of her getting a straight answer were pretty much non- existent.

You can go now, bitch, he informed her. Be back here first thing in the morning, though – I don’t want to have to knock on the wall again.

Mentally exhausted, Erin climbed to her feet. As she stood up she felt a warm glob of cum falling out of her asshole and trailing down her thighs. Her mind was full of questions and concerns, but her cunt only wanted one thing. Leaving her clothes in Alex’s bedroom she headed back into her own, needing some satisfaction. She knew they’d hear her through the walls, but it didn’t really matter at that point.
