On a free day of off-campus learning, wearing plain glasses and having no friends, I was left only to be groped and violated by my life guidance teacher, who had huge J-cup breasts. (Mitsuki Hyakuta MIDA-214)

[J-cup amateur girl x mature, erotic teacher] A simple, unassuming student from a lower social class, unnoticed by teenage boys who don't understand the true allure of women. But only the middle-aged erotic teacher doesn't miss the enormous breasts hidden beneath her clothes. Then, on a free day during a school trip, while the rest of the class is out having fun, he targets Momota, who is alone in her room, and begins to greedily violate her body under the guise of providing life guidance. He gives the innocent girl her first breastjob, facial ejaculation, and oral sex... completely educating her according to the erotic tastes of a middle-aged man. Until the very last day, he finds time to immerse himself in sticky, thick intercourse.
