In a bisexual threesome fantasy, a femdom trainer brings together two eager subs for a humiliating cock worship session. The subs, a man and a woman, are commanded to service each other's cocks while the trainer watches, critiquing their every move. The man's cock is engulfed in the woman's eager mouth, while she strokes and fondles his balls. The trainer, unsatisfied with their technique, forces the man to take the woman's cock in his mouth, teaching him the art of pleasuring another man. The session ends with both subs, faces glistening with saliva and cum, begging for more training.
