Alone in his room, a young man's thoughts wander to his stepmother, her luscious, round ass filling his mind's eye. He strokes his hardening cock, imagining her in revealing outfits, bending over, giving him a perfect view of her plump behind. His grip tightens, his breath hitches as he pictures himself gripping that ass, fucking her hard and deep. Lost in his fantasy, he doesn't notice the time, until a knock at the door brings him back to reality, his cock still throbbing with unspent desire.
