“Yuka”, a home-visit care worker, had a difficult life, and the price of having an old man massage her breasts at the destination was added to her life. The grandson of the old man who took a sneak shot of it was a classmate of Yuka's son "Kosuke"! Kosuke, who was shown the video, was shocked and strongly interested in her mother, the closest woman. And Yuka gives sex education with her own body in order to teach Kosuke the correct SEX, who has the false knowledge that if you give money like an old man, you can have SEX.
