Momoko, a mother who raises her only son Kiyoshi on her own and dreams of entering university. I work at a bento shop from early in the morning until late in the evening, and clean office buildings until late at night. Momoko finds out that her son's homeroom teacher has overwhelmingly poor grades in a mother-child interview, and thinks that admission by recommendation is absolutely impossible, so she consults her homeroom teacher about rewriting the school report. The homeroom teacher glared at the body full of ripe fascination with this ripe scent and committed it in the classroom. Kiyoshi witnesses the whole story, and that night, Kiyoshi beats his mother, who moaned in delight while being raped by her homeroom teacher.
