We're playing hide and seek with some friends and I try to hide in the same tight spot as you, there's not enough room so I sit on your lap. I move around trying to get comfortable and notice you're hard! Omg! You get embarrassed and try and move me off but I resist. It's not going away and my ass is squishing all up against it. I tell you that it's probably jsut better to jerk off and cum so nobody finds you here with this big boner. I help you out, showing my tits and nipples, teasing you throughout and finding this really hot. I count you down and you cum hard. Uh oh I think someone is coming hurry and put that away!
