A woman named Iroha Natsume started working at a female-oriented erotic massage parlor to pay her tuition fees. While she enjoyed her job and received good wages, she didn't want anyone to know about her involvement in what is commonly referred to as 'the industry.' As part of her personal rules, she avoided having sexual intercourse with clients. However, one day a married woman from the neighborhood came in for a treatment, and despite trying to hide her identity behind a mask, they were recognized by each other. The wife made a request for 'full intercourse,' under the condition that nobody would find out. Due to the circumstances, the masseuse had no choice but to accept.
