Unable to bear the sight of her daughter Rumina playing all day, Maki calls in a tutor. As soon as Rumina sees her tutor, Saji, she takes an immediate liking to him and starts seducing him, putting her studies aside. Unaware of the situation, Maki goes to his room to deliver tea. She hears her daughter's moans from the other side of the door...and witnesses her daughter having sex with her tutor. Seeing this, Maki, who is sexless, is more turned on by her anger than her pussy gets wet...
