Caught between demanding bosses, frustrated subordinates, and a troubled marriage, Sasaki has only one pleasure left: his monthly visit to a soapland brothel. Excited to meet the new girl recommended by the shop, he enters the room and finds his quiet subordinate Airi kneeling before him. When he tries to leave and pretend he saw nothing, she stops him and brings him to orgasm with devoted, full-body mat service. Intrigued by his hidden side, Airi soon begins secretly teasing him at the office as well.
