Your best friend never invites you over. You figure his step-mom is a hoarder or something but today, he finally invites you over, and you're surprised to find that his step-mom seems totally normal! Perhaps a little eager to please...but then he walks in, and starts fondling her tits! You can't believe what you're seeing, but you're not about to stop it. She's a total MILF, you've always thought so, and watching him pull her tits out before taking his dick and sticking it straight down her throat is undeniably hot. You try to hide your boner as she strokes, sucks, and throats her step-son, all the while acting like nothing at all is amiss! You'd never had thought that she was a free use slut!
