The stepmom and stepson, playing out their fantasy, begin on the sofa. She's the 'therapist,' he's the 'patient.' She starts with a sultry, slow striptease, her big boobs spilling out, her big ass jiggling. He watches, his cock growing, his eyes wide. She takes him into her mouth, sucking him deeply, her head bobbing. He groans, his hands tangling in her hair. She straddles him, his cock sliding into her wet pussy, her hips grinding. She rides him hard, their bodies slapping together, their moans filling the room. He flips her onto her back, her legs wrapping around him, and pounds into her until they both cry out, their bodies shaking with release.
