An intense, no-holds-barred training drama in a sealed room. The man is stoically and thoroughly sadistic, relentlessly tormenting the woman. She seeks pleasure and falls into a state of ecstatic trance. Mizuna Rei, as cute as a doll, hits climax after climax, exposing her lewd side to the camera.




















The content is as follows: 1. Bondage Training Bound, suspended, nose hook, gag, and nipple clamps. Led around by a collar, vibrator inserted, and puppy play. Intense spanking torture. 2. Toy Training Extreme anal close-ups followed by M-style restraint toy torture. 3. Sex Training Intense blowjob that makes her gag, and great eye contact with the camera while being hit from behind. Internal ejaculation. Mizuna Rei can play both S and M roles, and her acting ability depending on the situation is superb. She looks adorable screaming like a puppy while being spanked. It's great how she makes eye contact to show her pleasure during the act, and being handled roughly is also a plus. I'm not an S, but I found the content exciting to watch.
The male actor is Sagawa, and the vibe is similar to the recent 'Cage of Perversion' (Ryoki no Ori) series from ART. The beginning is quite hard-hitting with slaps (though few), nipple pinching, and butt spanking, but after that, there's no sign of whips, candles, or enemas... As the title suggests, the second half focuses mainly on electric massagers, vibes, fingers, and climax through sex. As a fan of Mizuna Rei from an S perspective, it's a bit lacking, but I'm rating it 'Good' because her expressions when getting slapped or having the collar put on were great.
