Daiki couldn't get that scene out of his mind. When he accidentally ran into his mother, Natsumi, in the bathroom, he ended up seeing her naked body. In that instant, he was captivated by her soft, touchable skin. Her smooth curves and glistening breasts... As a child, he'd never noticed such things, but now as an adult, an intense desire stirs within him at the sight of his mother, driving him into uncontrollable arousal. Meanwhile, Natsumi too begins to become aware of his burning gaze, starting to see him not just as her son, but as a man. As a result, their relationship grows deeper.
