Quick fuck with her mother-in-law's slut

Being able to fuck his mother-in-law's slut has become one of the great advantages that this uncle's marriage has, because he never imagined that his wife's mother would be a whore who is always anxious to be penetrated. The very bitch tells her that she opens her legs to wait for his cock and that he fucks her as soon as possible, because she worries that one day the daughter will arrive and catch them throwing a powder, which surely would become a great problem for everyone in view of the implications.
