Your new stepsis comes in to tell you it bothers her when you talk about your huge cock and how you can last for hours while you’re both at school, she says you’re lying but what would she even know about that! She says she knows a lot about this?? Now she’s the one lying, and you’re so sure you bet $100. She gropes at your huge cock (she admits you weren’t lying about that) and you cum almost instantly. Must have been a fluke! Double or nothing. She makes you cum in minutes with just her hand. Then she decides to bet the keys to your new car, and you think there’s no way your shy little stepsis could actually make you cum again. Somehow you end up gushing all over her face and tits?? And she’s taking the car keys?! ♥️
