Bound and gagged, the humiliated husband watches his wife and her lover engage in a heated BDSM session. He's forced to listen to their moans, watch her ride her lover's cock, all while he's denied any pleasure. His wife laughs at his pathetic state, 'You're nothing, a worthless cuckold,' she sneers, before making him clean up the mess left by her lover, rubbing his face in their combined fluids.
