Rika, a mother who has raised her son's guard with just one female hand. Recently, he seems to have a lover relationship with a colleague of the company, and I don't like the protection of the mother's complex. That feeling was too strong, and Mamoru sneaked into the bed at night. One day, Rika decided to bring her lover home. Mamoru leaves the room with discomfort, but when he returns to the room, Rika is entwined with her lover! Mamoru, who was shocked by her nasty appearance, went to the bedroom where Rika sleeps again to make her mother her own.
