Mahiro Tadai's underage body, who is abstinent and can't stop being horny, is played with as much as you want at a hot spring inn! As soon as she arrives at the inn, she is made to wear a remote vibrator and embarrassingly walks around the inn, and in the large public bath, she has humiliating sex with a strange middle-aged man! She gradually begins to release her masochistic tendencies, and has multiple orgasms where she urinates while being tied up and tortured with toys by a sadistic man, and then she indulges in the pleasure of being abused at a 4P orgy party!
