Married for two years, Mika was raised in a sheltered environment and is a little naive. But her daily happiness suddenly crumbled. Her husband's company went bankrupt and she was suddenly hit with financial difficulties. At that time, her brother-in-law Haruo introduced her to a healthy men's beauty salon and, feeling relieved, went to work there... but it turned out to be a sensual beauty salon that also offered hand jobs. Mika had no choice but to work there to make a living. But there was no way that a naive girl like her could suddenly do it... Haruo, fed up with her incompetence, forced her to teach him how to play under the pretext of training.
