Frustrated and horny, a submissive male is locked into a chastity device, his keys held by his dominant mistress. She taunts him, running her fingers along his caged cock, feeling it throb and strain against the confines of its prison. She strokes and teases, bringing him to the brink of orgasm, only to cruelly deny him release. Her humiliation is complete as she makes him watch her pleasure herself, his own cock aching and desperate for relief.
