The mascot girl 'Rie' of the massage parlor has H-cup breasts. Regular customers get excited by touching her chest during treatment and mistakenly think that erotic acts are okay, then forcefully push for them. Rie, who is diligent at work and never forgets her spirit of service, feels embarrassed but develops into an erotic massage using her breasts. She is told by a senior that this is new treatment guidance, has oil applied to her large breasts, and it escalates into sex.
