Curvy dark-haired beauty Kelly Divine is invited to John "Buttman" Stagliano's seaside villa for a steamy session of erotic punishment and rear-end training. Playful and well-endowed Kelly allows Buttman to gauge the deep division of her voluptuous buttocks and spank her plump cheeks with a stick. Kelly tweaks the peaks of her large breasts and inserts a huge vibrating toy into her backdoor.
Buttman caresses Kelly's feet, fixes heavy chains to her hanging labia, and clips clothes pegs onto her powerful rear end. Following the use of a medical tool, a stretching contraption, and various other unconventional adult toys, Kelly's wide open backside grasps a valuable lesson: "Keep on expanding!".
