A quivering slave, bound and at the mercy of his mistress, receives her brutal handjob instructions. She commands him to jerk off, her voice echoing in his ears, her hands guiding his. She laughs at his humiliation, his futile attempts to prolong his pleasure. She forces him to the brink, then backs off, teasing him cruelly. His body is slick with sweat, his breath ragged, as she continues her relentless torment, pushing him closer and closer to the edge, until finally, she allows him to erupt, his body convulsing as he spills his load.
