Naive girls are suddenly subjected to enema massage. The replacement clothing provided is extremely small, leaving them barely covered in bikini-like attire. As they change, confused and hesitant, the girls are made to lie down on the treatment table. Then, the cruel masseuse appears and begins, coating their taut bodies in oil until they glisten. Girls who have never experienced anal stimulation before squirm in confusion as their bodies involuntarily react to the touch. Unable to endure it, they begin trembling violently, eventually releasing massive amounts of fecal fluid with explosive force. This shocking depiction becomes the core appeal of the work.
