Riho is a girl who works part-time at a restaurant. While venting about her job, she decides to relax and enjoy a massage. However, during the session, the masseuse skillfully uses her words to gradually remove Riho's kimono. Starting from her shoulders, moving down her back, legs, waist, buttocks, breasts, and then... before she realizes it, she's nearly naked. Overwhelmed by pleasure, she ends up requesting an extended session—the "Special Meat Rod Insertion Course."
