You still share a bedroom with your slutty sister. It's a little weird but your parents are really strict and they think that by making her share a room with you, it'll stop her from being a slut and sneaking guys into her room at night. The problem is...it doesn't. She doesn't give a damn that you're there in the room, every night she sneaks a different guy in to fuck anyway. She thinks you're such a loser that you'd never tell and she threatens to make your life hell if you ever did. And she's right, you wouldn't ever tell. Because it turns you on so much to see her getting fucked like a slut every night. You pretend not to be awake but can't help watching and stroking your cock under the covers at the sight and sound of your slutty sister getting off and draining cocks right beside you. And you aren't fooling anyone, she knows exactly what a creepy perv you really are. She loves to tease you and put on a show, rubbing it in your face that you can only watch, that you'll never get to get to have her pussy, no matter how bad you want it. She fucks so many guys but she'll NEVER fuck you.
