The wife, collared and submissive, is forced to witness her husband's transformation into a sissy. He's dressed in lingerie, made to practice his feminine walk, and is taught to pleasure his mistress with his tongue. She laughs as he struggles, his face buried between her thighs, his pathetic erection evident in his panties. The wife's humiliation is complete as she's made to thank her husband's mistress for training him so well.
