G-cup with a godlike figure, Nonoka-san. More like a beautiful older sister than a stepmother, with a perfect physique where there's absolutely no waste in her proportions. She also properly possesses maternal instincts, which is really unfair. When her stepson confesses he's a virgin, she takes the initiative to undress and begins close-contact instruction to teach him about the female body. This is a work where the thrill of being a good mother while fully unleashing her femininity as a female, and having a raw relationship in a closed room, is irresistible.
