That's the way to hit that ASS, Next time put your legs between hers and then spread them apart and put your hands on the head order and GO TO WORK ON THATASS
While his butt is bouncing like this I want to climb on top of his butt rub my dick between his butt cheeks and hump his crack until I cum all over it. Feeling his butt bouncing underneath my cock would feel so good. My tongue up and down his cheeks kissing them all over.
