Saito is confused by how excited he is when he peeks into his friend's mother, Chitose. - On this day, when Saito came to visit his friend Momoyama's house, he witnessed Chitose masturbating. - The sight of it catches my eye. - I didn't know that aunts were so erotic... - Saito is drawn to the sight of Chitose, who continues to pant without noticing her gaze, and is unable to stay there. - I want to get closer to Chitose somehow. - However, Saito, who is a virgin and doesn't know how to interact with women, devises a very poor strategy.
