Maria, whose body is aching from her abstinence, is given a two-day, one-night humiliation training at a hot spring inn! As soon as she arrives, she is given a remote vibrator and takes a humiliating walk around the inn, where she serves a middle-aged man in the public bath! Back in the room, she is blindfolded and tied up by a sadistic man, who uses toys to torture her, making her squirt and climax repeatedly, and then she is fucked hard in a 4P orgy at a banquet, where she climaxes in agony! Eventually, her masochistic nature blossoms and she becomes a slave to the pleasure of being abused!
