Don't know how this topic hasn't come up yet; tried searching every which way, but I think it's super hot when a girl's getting it doggy and the guy rubs her asshole or puts his thumb in there. One of my favorites to do with my gf! Any recommendations? One of the hottest I've seen is with Vanessa Leon. She's riding the guy and he reaches around and sticks his finger up her ass, her eyes get real big and she giggles but she keeps riding and leans over and tells the guy she's never done that before. Haven't seen her do it in any other scene...
