Reika was always kind to her son (Takahiro), and Takahiro was also spoiled by such Reika. One day, Reika sees Takahiro masturbating in Reika's underwear. Reika acts like she doesn't care about the upset Takahiro. Takahiro timidly asks Reika. "Mother, can you make me a man?" Reika responded to Takahiro's feelings with her hands and her mouth, even though she was confused. However, that alone is not enough for Reika.
