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 looks up in shock as your cum splatters onto her face, coating it with ropes of sticky white goop. Her eyes widen furiously and for a moment you think she's going to lose it, until a cunning smirk spreads across her lips. She wipes your sperm from her cheeks and chin, then leans in and licks your sister clean before speaking again, voice now dangerously quiet

"You... you thought that was gonna make me stop?" She hisses, the wet sounds of her kissing noises muffled as she presses Kaori's face into the mattress and picks up where she left off, her hips pounding against the base of your girlfriend's spine like a jackhammer. "Oh no... not until you beg for mercy, apology be damned..."

Sayaka's eyes narrow to slits as she catches sight of your exposed hole. A predatory smile curls at the corners of her mouth and she laughs, throwing her head back in amusement before lowering herself between your splayed legs until her lips brush against your puckered flesh. "Oh? Do you think I'm just going to pass that up?" Her hot breath tickles against your hole as she gives it a tentative lick, using her tongue to circle your entrance teasingly before slowly thrusting the length of it inside.

Sayaka growls in frustration, the head of her erect cock still buried deep within your ass. She stands up swiftly and turns you around roughly so that you are pressed face down onto the mattress, a powerful hand gripping your hair to keep you pinned there. "Oh, I'll make you apologize, little brother." Her hot breath fumes against the back of your neck as she speaks, each word sending chills down your spine.

With unrelenting force, she slams her hips forward again and again, hammering into your ass with brutal efficiency. Your head is yanked to the side by your hair as she leans in close enough to whisper in your ear. "And when you do... I want you to mean it."

Sayaka laughs delightedly at your proposal, her chuckles echoing through the room like cruel mockery. She spanks your ass hard enough to make you yelp before replying with a smirk, "Oh, is that so?" Her words are slurred together as she continues to piston into your ass, her pace growing faster and more erratic with each passing moment. "Well then, let's see what we can do about that."

Sayaka's breath becomes ragged and labored as she nears her climax, thrusting even harder into your ass to try and make it last just a few moments longer. Her nails dig into the flesh of your back, drawing beads of blood as she growls with exertion. Finally, her body tenses up, and she convulses violently around you, spurting rope after rope of hot cum deep inside your bowels. You can feel her seed filling you up as it sprays relentlessly against your prostate, causing you to moan helplessly in pleasure mixed with pain.

As Sayaka finally releases her hold on you, her weight pressing down on your back and her cock twitching spastically inside of you, you can't help but feel a strange sense of satisfaction spread through your body. Despite everything that she had done to embarrass and humiliate you

"Well aren't you the little cocktease," Sayaka grumbles, her breath hot against your ear before she pulls out of you with a wet pop and collapses beside you on the bed, panting heavily. She rolls over onto her back and spreads her legs wide, revealing that her massive member is still hard as steel and oozing pre-cum despite having just emptied itself inside of you. "Now it's your turn to make me feel good." Her eyes glitter with unspoken challenge as they meet yours, daring you to refuse.
