"Wait, you're a shut-in?" Mayu came to support her friend's son, who had suffered deep emotional trauma after a failed first sexual experience. Secretly, she was also driven by her own pent-up desires, using counseling as an excuse to get close to him. Determined to prove herself by becoming skilled in bed and showing up the girl who once mocked her, Mayu used her voluptuous figure and seductive techniques to gradually draw him in. The pure and innocent young man found himself captivated by her, increasingly fixated on Mayu, eventually filling her womb with creampie after creampie. Her skillful seduction and warmth slowly transformed his heart.
