Big ass stepmom fucks her stepson while they are alone at home

A voluptuous stepmom with huge tits and ass fingers her pussy, and her huge labia swallows the finger as she touches her clit first over her dress and then lifts it to touch herself better. She touches herself while showing off her huge tits and ass, and her stepson sleeps on a bed next to her. She then sits on the bed to touch herself more comfortably, waking up her stepson, who has an erection after the show he saw. She is very sorry but also very horny, so she decides to take care of the problem with her own pussy.
