In a dimly lit dungeon, a strapon-clad femdom takes charge, binding her submissive's wrists and ankles to a sex machine. She strokes his chastity-caged cock, feeling it throb with desire. She lubes up her strapon and penetrates his eager ass, setting the machine in motion. As it pounds into him, she reaches around, rubbing his prostate with expert fingers, drawing out guttural moans. She milks his prostate, coaxing four powerful orgasms, each time capturing his cum with a waiting mouth or gloved hand, savoring his prostate-cumshot.
