Ms. Mars walks in on her horny teenage step-son (Matt Bailey) masturbating in the living room. She feels a mixture of surprise and arousal as she spots just how big his dick has gotten. She takes a seat next to him as he tries to hide his shame and interrogates him on his sexual experience - he says he's fucked lots of girls, but mommy knows he's lying. Thinking it's time he finally experiences the real thing, she reaches over and grabs his cock and starts stroking it. He's shocked, but turned on, and can't help but go along with it. Things ramp up quickly as she starts blowing him, then making him eat her ass and fuck her in a variety of positions until he shoots a nice, big load all over mommy's face. Also step-mom has a dick - just go with it.
