My step-sis knows exactly what she's doing when she parades around in those tiny gym shorts, her bubble butt bouncing with every step. She teases me relentlessly, bending over and wiggling that perfect ass in my face until I can't take it anymore. I jerk off watching her, but she catches me and helps me finish, and then she's so hot I can't help but go for round two, cumming all over her round cheeks.
