A college-age sub, eager to please his mistress, is presented with a chastity belt and a humility clause. She parades him around, feet worship and spanking sessions abound, until the grand finale: a strapon-fueled pegging. She straddles him, her toy slipping in easily, and rides him, her moans of pleasure echoing in the room. He's reduced to a quivering, begging mess, his orgasm denied, his body marked with her ownership.
