Since the birth of her son Kenzo, Kaoru has been frustrated because she has lost all of her nightlife. One day, Kato's wife, Haruko, who lives next door to her, goes on a trip abroad, so she will take care of her son Yasuharu for a few days. Kaoru's chest was pounding. That's because she had heard from Haruko that she had a big dick... On the day of the meeting, Kaoru couldn't control the pain in her crotch when she heard that her son had a 17cm penis in a conversation between Yasuharu and her son.
