Nana Yagi visits the home of an adult masochistic man who already has a girlfriend in this unscripted documentary. She delivers the little-devil femdom his partner refuses: soaked nipple play, edged blowjobs, collar-and-leash piledriver cowgirl, arousal oil massage, intimate NTR sex, and post-orgasm handjobs that make him squirt. Gentle eye contact and whispered affection soften the cruelty. "Just for today, I'll be your girlfriend." With betrayal as the perfect spice, he cannot resist.
