Something that happened during a meal. - Tooru crawls under the table and caresses the thighs of his mother-in-law Hisayo. - When she tries to talk to her husband about it, he doesn't talk about it, and when she convinces herself that it was all her imagination, she runs into Tooru, who is admiring her underwear in the changing room. - Too furious and attacked, Hisashiro says, ``No! We are father and son.'' She uses all her reason to stay back, but she ends up blocking her son-in-law with her mouth. - His uncontrollable urges escalate and he finally demands all of Hisayo!
