Ichihana tries to clean her son's room in the middle of adolescence. When I entered the room, I found all-you-can-eat rolled tissue and lewd magazines. Ichihana's crotch, which had been absent recently, gets wet due to the smell of green that can be seen in the room, and she masturbates as it is, thinking that it is useless. And the son who had just returned home witnessed the situation. My son can't control his desires and attacks the unpleasant mother who is different from usual.
