I've been fucking my sisters husband behind her back for months and she only just found out, i've told her that i could probably teach her a few things about how to please her husband to make sure he doesn't cheat again. I make her watch as i show her how to pleasure her husband with my hands, mouth and pussy, but i then tell her that theres something that her husband really enjoys, ANAL! i then use a butt plug and suck his cock some more before i take it out and take his big hard cock in my ass until he cums deep in my asshole, i finally tell her that he loves to watch me cum for him so i make them both watch as i play with myself until i cum, who knows they may even need another lesson
