I went to my friend's house to play, but he wasn't there, so I waited for him, and his sister was exercising in a leotard! I was so excited that I didn't know what to do with her, and she showed me her leotard! Then she rubbed her ass, which was about to spill out, against my face and crotch! I couldn't help but get a boner! My friend's sister was so excited that she asked for my dick, and I fucked her like crazy!
