Koji, a husband whose favorite phrase is "From now on, we will enter an era of different cultures," applied to the office to become a host family for a homestay with the aim of interacting with foreigners. He immediately received a reply and agreed to a two-week homestay. On the day of the visit, two black men named Michael and Chris came to the Ikimoto family home. Koji and his wife Tsubasa, who had been looking forward to the two's arrival, treated them to Japanese food that is registered as a world product. After the banquet, they decided to take a bath... and Tsubasa accidentally saw the two men's huge dicks. Their huge size Tsubasa's crotch begin to ache.
