A cute maid with a short haircut, Ran, is sent to the room of a creepy perverted master. Ran endures as the master relentlessly touches her fair skin, pink nipples, and thick pubic hair. It seems that he wants to train her to be the kind of maid he likes. He forces her to give him a blowjob and finger her to develop her sexual sensitivity, makes her masturbate in front of him so that she feels embarrassed, and thoroughly teaches her the taste of cock... A few days later, the maid Ran is transformed into a magnificent perverted slut maid.
