He was hanging out with his hot, new stepsister when she moved a certain way and he got a glimpse up her skirt to see her panties. Catching him in the act, she decided to give him a treat so she shocked him by pulling her dress all the way off. She wasn't wearing a bra so her big tits spilled out then she pulled her legs back, slipped her panties to the side, and finger fucked her wet pussy. Having him watch her get herself off only turned her on and made her orgasm that much more intense. That is how you get to know someone!
