Yuusuke, a high school student, finds himself in a unique and intense relationship with his mother, "Haha-san," a strict but caring woman who has always pushed him to study hard. From a young age, she has made sure he follows a rigorous academic path, even sending him to a strict after-school tutoring program. But as he enters puberty, his thoughts begin to drift from books to something more personal—his mother.
At first, Yuusuke's distractions lead to a drop in his grades, and his mother is furious. Yet, instead of punishing him further, she offers a surprising solution: a nightly ritual of sexual release, allowing him to focus on his studies. This arrangement is not just a reward—it’s a carefully planned rule-bound experience. Yuusuke must send a message before each session, arrive at a specific time, and follow strict guidelines: no kissing, no touching, no extra time. It's all about efficiency, a quick and effective way to satisfy his desires and return to his books.
Each night, as he enters the dimly lit room, he finds Haha-san already waiting for him, ready for their quiet, intimate encounter. She is calm and composed, yet her soft moans and gentle encouragement show that she, too, enjoys this special bond. The more he indulges, the more he feels his connection to her deepen.
As time goes on, Haha-san begins to let go of her usual restraint, allowing herself to fully embrace the moment. Their nightly routine becomes a secret, a private escape from the pressures of school and the world beyond. And as Yuusuke returns to his studies each morning, he knows that with Haha-san by his side, he can face any challenge—because he has the most amazing support system in the world.
