Ai is a female college student who is having an affair with a man who has a wife. I was so excited that I thought I was on a normal hot spring trip. However, the inn they arrive at is an obscene hot spring that is famous for voyeurism and orgies, and the mistress who brought her without informing Ai of this fact issues a series of humiliation orders one after another for the purpose of training Ai. Through repeated training, she becomes a masochistic woman...




















Mukai-san looks so cute with her short hair. With content like body graffiti, golden showers, and bondage under a yukata, it's quite intense and enjoyable. These kinds of concepts really suit her.
This series is great for the golden shower scenes, not just the bukkake. Maybe because it's chilly, seeing her get goosebumps or shiver from the cold is a real turn-on. Personally, I love the flow of the cleanup blowjob after the pissing, leading right into a cumshot.
I love the short hair and her toned body. The exposure scene by the car is great; this series is consistently good. Her dark nipples look so delicious I can't stop replaying that part. The hands-tied-behind-the-back pose is also nice, and since she has a decent bust, the bondage look is very aesthetic. Seeing her kneeling and performing oral while tied up is great, and the final shibari scene is excellent too. Those dark nipples are just perfect. It's fun watching her get used by the guys, but it would've been even better if she were more aggressive with it.
They tie up and train Ai Mukai, who has a toned, exquisite body. She's cast as a college student having an affair, but the hot spring trip was actually a setup for training. First off, the beauty of her body while bound is magnificent. Then, in the open-air bath and the hotel room, she's subjected to gang-bang training by strangers. Ai gradually reveals her masochistic side, sinking into pleasure. There's a scene where her abs are slightly visible, which is truly captivating. The cowgirl scene is also top-tier. Plus, there's perverted play like urination and bath-pee. Overall, it was a great watch, but I didn't like the scene where they drew graffiti on her body. Since Ai has such an exquisite figure, it just ruins the erotic beauty. ...I wonder, are the hot springs used for AV shoots always filled with this kind of eroticism?
