"Mom, what are you doing?" the stepson asks, shocked but aroused, as his blonde stepmother, a busty pornstar, enters his room. "I heard you needed some help with your... 'problem'," she purrs, pushing him onto the bed and pulling out his throbbing cock. She expertly strokes and sucks him, her hungry eyes locked onto his. "You've grown so big, baby," she whispers, climbing onto him, her soaking pussy sliding down his shaft. She grinds and moans, her big tits heaving, as she fucks him, their taboo passion consuming them.
