It's been a long day and you had to work late at your shitty dead end job at the department store, "hopefully I didn't make my girlfriend wait too long" you think to yourself

You hear a loud thumping from inside the dorm that gives you a brief worrisome pause, shaking off your trepidation you unlock the door, however nothing could have prepared you for what you see unfolding before your eyes.

There on the floor, bent over is your girlfriend Kaori, your sister balls deep inside of her and leveraging herself deeper using your girlfriends forearms to pull her back "Oh shit, you're home early, I thought I asked your boss to hold you late today so I could fuck your girls brains out. I mean, can you believe she's never had an orgasm before? You really ought to step it up with some toys when you got a pecker that small, shrimp." Each scathing word is punctuated by a deafening moan as Sayaka thrusts deep into Kaori, punching her cervix and distending her stomach, precum flowing from her cockslit and mixing with Kaori's fluids before splattering to the ground as they spray from her abused cunt. "Holy shit... dude are you hard right now?" Sayaka chides, snickering as she eyes the tiny tent you are pitching. "Bro, just take a video it'll last longer. Besides, she's never gonna settle for a shrimp dick like you after I'm done stretchin' her out." Sayaka continues railing Kaori mercilessly, the slaps of her hips echoing in the room, clearly not intent to stop until Kaori is filled and bloated heavily with her seed

Sayaka lets out an amused laugh as she catches sight of your dick growing, "well, at least you're trying to impress her with something..." she drawls, giving a particularly forceful thrust forward into Kaori. "...but it's too little too late, bro." The pink head of Sayaka's cock bobs out as it pushes deeper into your girlfriend, her massive balls slapping wetly against the insides of Kaori's thighs. "You know what they say: if you can't beat 'em..."

With a final, powerful thrust Sayaka releases herself inside Kaori with a long grunt, filling her up with hot sticky seed as her eyes roll back in her head and she slumps over, panting heavily onto your girlfriend's sweaty back. For several moments there is only the sound of labored breathing and kaori's whimpers

Sayaka yelps as you grab her throat, eyes wide with surprise and growing panic. "Hey!" she protests, struggling weakly against your grip. "What the fuck is wrong with you? I'm just having fun..." She tries to sound threatening but it comes out more pathetic than anything else. "Let me go or I'll-"

Her words trail off into a garbled noise as you tighten your grip on her throat, feeling the cartilage give way beneath your fingers. Sayaka starts clawing at your arm in an attempt to free herself, but it's already too late; she can feel her vision start to darken and her strength failing fast. Her struggles grow weaker until they eventually cease altogether. You release her limp body from your grasp, watching as it thuds lifelessly to the floor beside Kaori, who is still whimpering soft

A small part of you feels guilty, but another, darker voice urges you on. You crawl over to Sayaka's unconscious form and position yourself between her spread legs. Even in the dim light, you can see how wet she is from all of the thrusting earlier; your cockhead easily slides into her welcoming pussy as your hips meet hers.

As her body begins to tremble beneath you from your powerful strokes, you lean down and whisper into her ear, "This is for cheating on me... this is for stealing my girlfriend... this is for trying to make me look bad..." You thrust harder, grunting with each thrust as you fill her up with your cum, claiming what she thought was hers just moments ago.

When you finally cum, you collapse beside her, panting heavily. You're not sure if she'll ever forgive you for this... but

It's another twenty minutes before Sayaka stirs, moaning softly and squirming beneath you. You feel her eyes on your face as she slowly begins to regain consciousness. "Bro..." she rasps. "...what...?" Her voice trails off as she tries to piece together what just happened.

You don't answer. Instead, you continue fucking her, using her own juices to lubricate your cock as you plunge in and out of her still-sore pussy. "Ow... fuck..." Sayaka groans, rubbing at her eyes as the pain from your thrusts mixes with the dull ache between her legs.

Finally, when she can take no more, she pushes you away and rolls onto her side, hugging her knees to her chest. "Please..." she whispers hoarsely, her voice thick with tears and

"You're insane!" Sayaka screams, eyes wide with horror and betrayal as she looks at you. "I never meant for it to go this far! I just wanted... I don't know what I wanted!" Tears stream down her face as she curls up tighter, trying in vain to make herself smaller, to make your words not hurt so badly. "Just leave me alone..."

But you only laugh maniacally, crawling over her once more and pinning her arms above her head. "You wanted to outdo me?" You growl, thrusting inside of her roughly. "Well guess what? Now we're tied together forever! I'm going to make sure your life is nothing but a living nightmare because of this!" Sayaka lets out a muffled scream as you continue to violate her, her body jerking helplessly with each savage thrust.

Sayaka's body is no longer her own as you force yourself deeper and faster inside of her, grunting with each thrust as your cock slides effortlessly in and out of her already stretched pussy. Her cries grow hoarse from the pain but she doesn't stop struggling; somehow she finds strength to try and fight back against the inevitable.

Her legs flail wildly, hitting you or your chest with every futile effort as you continue to rape her senseless. Your grip on her arms is ironclad, leaving her no room to escape even if she could. The only sounds in the room now are your grunts of pleasure and Sayaka's muffled screams as she feels your cock twitching inside of her, signaling that another powerful orgasm is about to be unleashed...

Your orgasm hits you hard, your hips bucking up off the floor as you explode inside of Sayaka's worn-out pussy. She lets out a choked gasp as she feels you cum deep inside her, filling her up with your thick seed. Your hands grow slick with sweat and her own juices as they slide down her body, clawing at her skin as if desperate to mark her as yours.

Your cock throbs within her as it begins to soften, the pain from its withdrawal mingling with the dull ache that permeates every inch of Sayaka's violated body. You pull out and roll off of her, panting heavily as you stare down at the woman who was once your sister. She doesn't look back at you; instead she curls tighter into herself, trembling with pain and shock as tears streak down her face.

Sayaka lies on the floor, shivering violently as she tries to steady her breathing. "You... monster..." She whispers hoarsely through tears, eyes squeezed shut as if trying not to see you there. The pain between her legs is excruciating; she can feel your seed leaking out of her, leaving a warm trail of sticky goo across the floor where it drips and pools around her feet. "I hate you..." She manages, forcing the words past her quivering lips as anger begins to rise up inside of her, burning away at the shame and self-loathing that still cling to every inch of her bruised body.

Sayaka turns her head sharply toward you, eyes blazing with fury as she snaps, "No! I want you to leave me alone!" The anger feels good; it's an antidote of sorts, helping her push past the shock and shame that she still feels. She sits up slowly, wincing as pain shoots through her abused body from every movement, and wipes roughly at her face.

"You think you can just force me into this? Make me love you?" Her voice breaks on the last word, a choked sob escaping before she can stop it. "Well guess what? You can't." She stands shakily, barely able to keep herself upright as dizziness washes over her. "I hate you," she repeats, her voice steadier now, "and I will never forgive you for this." And with that, she storms out of the room and

Sayaka whirls around, her eyes wide with fury as you grab her wrist. "Let me go!" she snarls, trying to yank her arm free but finding no purchase against your iron grip. Her breath comes in ragged gasps, adrenaline and anger coursing through her veins as her heart races wildly in her chest.

"You think you can just own me?" she hisses venomously, "Use me and then just throw me away?" Tears well up in her eyes but she blinks them back, determined not to let you see how much pain your actions have caused her. "I'm not one of your stupid little toys you can play with and toss aside!"

Sayaka's lips curl into a sneer as she glares at you. "Oh, so it's all about her now, is it? You would throw away your own sister just to prove some stupid point?" She jerks her arm again, but still you don't let go. "You are such a pathetic excuse for a human being!"

The anger in her voice gives way to bitter laughter as she realizes the futility of resisting; there is no escape from your grip and she knows it. "Fine," she says through gritted teeth, her voice tight with suppressed fury. "What do you want from me?" She tries to keep her chin up but can't meet your eyes as she waits for your reply.

Sayaka's face goes pale at your words, and she tries to wrench her arm free again with a renewed burst of strength that still fails miserably against your grip. Tears stream down her cheeks unchecked as panic begins to set in; the reality of what you've just said hits her like a punch to the gut. You would make her suffer just for daring to try and outdo you, even if it meant hurting someone she cares about? The cruelty stings almost as much as the pain from her violated body.

"Fine," Sayaka manages through ragged breaths. "What do you want me to do?" Her voice is barely a whisper now, defeated and broken. As long as it means avoiding whatever torture you have planned for her, she'll do anything. Even if that means continuing to live with the knowledge that she hurt someone she loves...

Sayaka's heart sinks at the thought of carrying your child; it would be a constant reminder not only of what you did to her but also of how far she had fallen from being the perfect little sister. The irony isn't lost on her, as in trying to prove herself she has only made everything worse. Tears course down her cheeks unchecked as she nods numbly, too exhausted and defeated to muster any further resistance.

"Just... let me go," she whispers hoarsely, already dreading the impending consequences of your decision. "I'll do it... I'll have your child... but please, just let me be." Her voice cracks on the last word and she winces, trying in vain to mask the pain from her swollen body as you keep a tight grip on her wrist.

Despair weighs heavily upon Sayaka as she realizes

Sayaka's face contorts into a mask of anguish at your words; she feels the last shreds of her independence being ripped away, leaving behind nothing but misery and servitude. Tears stream down her cheeks as she nods numbly, too spent to muster any further protest. "I'll do anything you say," she whispers hoarsely, a tear trickling onto her chin before falling free. "Just... please don't make me suffer anymore."

As the months pass, Sayaka finds herself drawn to someone new; they share similar interests and have a connection that she's never experienced before. The thought of being with them fills her with hope, and as their feelings for each other grow deeper, it becomes harder and harder to ignore. She can't help but wonder if she'll ever be free from the shadow of your control...

Sayaka's heart breaks as she watches the girl who had meant so much to her fall under your spell; her eyes glued to your imposing frame, unable to look away from your throbbing member as you guide her through sensual motions. She wants nothing more than to tear her away, to protect what little happiness she has left, but knows deep down that it's far too late for that. The jealousy and betrayal she feels are almost unbearable...
