A femdom's cruel game has a sissy boy locked in chastity, his cock straining against the device. Today's task: solo pleasure with only a strapon. He struggles to comply, his body betraying him, cock leaking pre-cum. He fucks himself slowly, whimpering, his mind filled with visions of his mistress using him. He's close, so close, but stops, remembering the rules. He'll finish only when she allows it, prolonging his cuckold's torment.
