When you use the blankets to wrap a girl up like a burrito then while shes stuck inside you can just totally fuck the shit out of her and she can't do anything. Then you can move her around to different positions and whatnot (or you could even poke a little hole in the back and do her anal style!)
I had that bitch corn rolled all night! She couldn't do anything to stop my anal adventures.
The act in which, after performing anal sex, you remove your penis from a woman's ass and rub the residual shit on her stomach in a circular motion. Then, jerk off on her stomach and spread the semen around with your penis, mixing it with the shit in a spiral shape.
