"Mike Mancini, a doctor with a secret fetish for his blonde, curvy stepdaughter Ava Davis, finds himself in a compromising position when she visits his clinic. Julia Robbie, a therapist, is brought in to help Mike control his urges. But as Ava stretches, her big tits bouncing in a tight blouse, Mike's professionalism falters. He envisions her luscious mouth wrapped around his cock, her braces gently scraping his skin as she sucks him off. The clinic's couch becomes a battleground for their forbidden desires, with Ava's big ass jiggling in doggystyle, and her tight pussy struggling to accommodate Mike's massive dick. The room fills with the sounds of their ragged breathing and the wet slapping of skin on skin as they teeter on the edge of taboo."
