A submissive is trained in the art of orgasm denial by his stern mistress. She uses her skilled hands to bring him to the brink of ecstasy with a slow, torturous handjob. As he's about to cum, she slaps his face, humiliating him and making him hold back. She repeats this cycle, each time bringing him closer to the edge, only to deny him release. His cock glistens with pre-cum, throbbing with need, but the mistress maintains control, relishing in his desperation.
