Ryoko, who feels tired from just taking care of her husband and his child Mamoru every day and can't hide her embarrassment about the existence of her ex-wife who shows up from time to time, indulges in lonely masturbation as if to distract her loneliness.

At first, Ryoko resisted her son, who was unbearably ripe and munching on her flesh, but gradually began to sob.
