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 grins as she pumps deeper into Kaori, hitting her cervix every thrust and releasing obscene grunts of pleasure with each impact. "I didn't think you were even close to ready for this," she teases with a wicked gleam in her eye, glancing over at you. You feel utterly useless as your sister mercilessly takes what is supposed to be yours, "but I guess I just found something better to do with it." Her words are thick and slow, each syllable a wet collision against Kaori's clenching flesh.

Your cock strains at its confines, achingly hard beneath your clothes. You watch helplessly as your sister pushes deeper and deeper into your girlfriend, making her arch her back and writhe on the ground in pleasure and pain. The sight of Sayaka's massive member stretching Kaori to the breaking

Sayaka glances over at you again, a cocky grin curling her lips as she watches you struggle with your growing arousal and the frustration of being left out of this. She doesn't seem to mind that you can see her naked body glistening with sweat as she fucks Kaori, in fact it only seems to heighten her pleasure.

"You know," Sayaka purrs, thrusting deeper into your girlfriend and hitting a particularly sensitive spot inside of her, "I've been wanting to play with you for so long. Maybe once I'm done here..." She trails off suggestively, moving her hips faster and harder against Kaori as she continues to dominate both of you in this intimate, humiliating encounter.

Sayaka eyes you warily, but the mix of challenge and desire in her gaze gives it away; she wants this as much as you do. She thrusts harder into Kaori, taking advantage of your distraction to push deeper into her than before. You reach out, seizing Sayaka's hips and grinding your cock against hers as you feel the girth of her shaft slide effortlessly between your legs.

You push deeper, driving her into Kaori as if trying to force yourself in through some perverse version of sexual osmosis. The feeling of Sayaka's flesh against yours, the heat and strength of her body pressing you into submission, ignites a fire inside you that burns away all rational thought. As she slams into your girlfriend with brutal force, you grip tighter, refusing to let go until either one of them collapses beneath you in exhaustion.

Sayaka grunts and hisses, her breath hot against your ear as she struggles to maintain control over both of you. Her massive cock slides effortlessly in and out of Kaori's sodden cunt, stretching it impossibly wide with each thrust. You feel the weight of Sayaka's breasts pressing against your back, her hard nipples digging into your skin as she moans and curses through clenched teeth.

As you push yourself deeper into her, Sayaka's hips buck wildly, her body convulsing with pleasure as she tries to match your frantic rhythm. Her movements grow more chaotic, less controlled; a testament to the raw passion coursing through her veins in this moment. Your hands clutch at her ass, digging into the soft flesh as you ride out this insane orgasmic storm.

The room is filled with the

Sayaka lets out a loud, bestial moan as you roughly fuck her and thrust your cock inside her, hard enough to send painful jolts of pleasure through her body. Her own lust-fueled rage takes over now, and she begins to match your intensity with even more brutal force. Her hands grip at your shoulders, clawing into the flesh as if trying to rip it apart with her nails, while her other hand reaches between your bodies to find Kaori's swollen clit. She massages it roughly, circling and flicking until the small nub is bright red and throbbing with need.

"Oh fuck!" she gasps as another orgasm washes over her, shuddering through her body like an earthquake. Her thighs tighten around your waist, trapping you inside of her as she comes hard, milk squirting from

You feel the force of Sayaka's climax rock your entire body as she comes, her muscles tensing and spasming around you. Her hot juices splatter against your cock, making it even slicker as you push deeper into her, determined to find release yourself. With a final, violent thrust, you explode inside of her, emptying your seed deep within her womb as she cries out in ecstasy beneath you.

Your body trembles with the intensity of your orgasm as Sayaka's grip on you loosens ever so slightly. Kaori lies panting and used between the two of you, her insides still throbbing from the rough treatment they've received tonight. You stare down at her, a strange mix of lust and tenderness in your heart. For now, though, Sayaka seems to have stolen the show, both literally and figuratively...

Catching your breath, you can't help but glance at your once girlfriend. Despite the rough treatment she received tonight, there's something about seeing her like this that makes you feel... jealous? Maybe a little possessive? You wonder if these feelings are just a result of Sayaka outperforming you in every way tonight or if they go deeper than that. Either way, it leaves an unsettling sensation in your gut.

Sayaka's breath is ragged as she lies beneath you both, her chest rising and falling with each laborious gulp of air. Her eyes meet yours from across Kaori's naked body, and there's a challenge burning bright within them. You can tell that she's enjoying this power trip, but it also seems to have awakened something primal in her too. The question is: will you let her continue to push your buttons like this... or

"Next time," you find yourself saying through gritted teeth, "leave some for the rest of us." You know you're being petty and childish, but you can't help it. There's something about seeing Sayaka have so much fun that makes you feel... less than. Maybe if she focused more on you instead, you could finally show her what good sex really is.

Sayaka rolls her eyes, unimpressed by your childishness. "Oh, don't be such a sore loser," she says with a laugh that only serves to grate on your nerves even more. Kaori, meanwhile, watches the exchange with interest, her body still twitching in the afterglow of their shared orgasms.

You look at her, feeling an unexpected pang of guilt. She's been through so much tonight... and yet somehow, Sayaka came out
