A new chapter in the cuckold's life begins as his mistress introduces him to his 'trainer' - a muscular, well-endowed man. The cuckold is made to kneel, naked and exposed, as his mistress and the trainer discuss his shortcomings. The trainer, amused by the cuckold's predicament, strokes his growing erection, taunting the cuckold with its proximity. The mistress orders her slave to service the trainer, making him lick and suck the hard cock, all while she watches, critiquing his every move. The cuckold's humiliation is complete as the trainer cums on his face, the mistress laughing as she wipes the semen away with her thumb, forcing the cuckold to lick it clean.
