Stepmommy fucks stepson when stepdad is resting

Stepson comes to fuck stepmommy again when her husband is resting. They did before and find it so good that they want to fuck constantly. Must be quiet so stepdad does not understand. She was horny because her husband nit fucked her for a week. Stepson wanted to fuck her in the ass and she accepted because stepdad's cock is too small and soft for ass fuck. Stepmom and stepson were both satisfied.
