I work out at home every day and my sister asks me to be her personal trainer since she wants to lose weight. The first thing I explain to her is how to do squats and I can't help but touch my dick when I see her squatting. I decide to go in and invent some special squats for her, on my cock of course. She hesitates at first, but then I feel her grab my cock and shove it into her pussy. She has a very tight pussy and like all Latinas she is very hot. I fucked my sister in every position imaginable and even fucked her mouth mercilessly!
