A curious pornographer captures the intimate dynamics of a femdom couple's cuckolding ritual. The mistress, bored by her cuckold's inadequate size, trains him to be her bisexual plaything. She brings in a well-endowed stranger, making the cuckold watch, touch, and ultimately suck the intruder's cock. The cuckold's humiliation is palatable, his cries of protest echoing in the room, yet his body responds to the taboo pleasure, his cock hardening despite his shame.
