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, will go on an overseas trip, so I will take care of my son, Yasuharu, for a few days. Kaoru's chest was pounding. That's because I heard from Haruko that "Yasuharu's cock is big"... On the day of the meeting, Kaoru couldn't control the pain in his crotch when he heard that Yasuharu and his son had a 17cm penis.
