A young man is feeling a bit down in the supermarket break room. A cheerful part-time working wife sympathetically listens to his troubles and tells him that he turned 20 as a virgin. Moved by his pure troubles and frustrated by his recent lack of sexual desire, she offers up her own body to teach the virgin the Iroha of sex. In the end, it turns out that she's just a perverted wife who wants to get a taste of an unused young cock.
