It's the first weekend of your sophomore year of college and your fraternity is throwing an absolute rager to welcome this year’s freshmen. Everyone who is anyone is at this party – and I mean EVERYONE, including your slutty sister who just so happens to be a freshman on campus this year. Sometimes you hate being big brother to the hottest girl at school – a few of your friends have already asked you to set them up with her, and their constant hazing is starting to get under your skin. She’s YOUR sister, after all – and you find yourself becoming strangely possessive of her... but not in the way you thought you would. Things heat up as the party stretches on through early hours of the morning, and as you’re finishing your shift mixing beverages you see a line forming for the bathroom... but wait a minute, why is the line leading to a bedroom? Just as you notice this out-of-place queue the bedroom door opens, and a college senior walks out in with his face flushed and his pants unzipped. He high-fives the line up as the line of tipsy men roar and pat his back. The crowd moves forward as the next person in line steps forward, and you catch a glimpse of what lies on the other side of that door... it’s your fucking sister. She’s alone and blindfolded, wearing nothing but her lacey underwear. She wipes her mouth and laughs before taking a generous swig of her beverage. “NEXT!” she shouts as the crowd cheers. You feel your face flush hot with rage and shame – what the fuck is she doing? It’s her first week of college and this is how she wants everyone to remember her for the next four years? Without thinking, you barrel through the rowdy mass of your sweaty peers. Ignoring their loud groans and complaints, you push to the front of the line and elbow your way into the bedroom. “Party’s over” you growl at the unruly group behind you as you slam the door closed. Once inside of the room, you bolt the lock and swivel to face your sister. You're prepared to unleash an earful of fury upon her - but when you open your mouth, nothing comes out. Instead, you find yourself staring transfixed. Her breasts are spilling out the sides of her red lace bra and glowing under the multi-coloured party lights. Her hair is dishevelled, and her lipstick is smudged... and the most stomach-churning detail of all is a wet glob of semen coating her chin. As she turns her head towards the sound of your footsteps, the light catches a trail of cum dripping down her neck onto her collar bone. A sloppy fat gob of jizz sticks to a long red strand of hair caught under her blindfold. “Well? Are you just going to stand there?” She asks, slightly slurring her words. You flush hot again, but this time it’s not just anger. Your cock twitches in your pants. It’s suddenly so painfully stiff that you can’t stop yourself from doing what you do next. Your index finger and thumb squeeze her greedy mouth open as you grip her wet and sticky chin in the palm of your hand. She laughs and opens wide. Before you know what’s happening, you’re sliding your rock-hard cock right into into your little sister’s mouth.
