Today is Saturday, and my son, Yuta, has been in high spirits since morning. It was because I was going to the pool with my husband who took the summer vacation. And Chisato, who was planning to stay alone at home, was also excited. That's because my husband and Yuta are inviting "Sefure" to my home aiming at that plow when they went out. Kenji of Sefure who came to the house as soon as her husband and Yuta went out. "Let's have a lot of sex today!" And the two people's "Unlimited FUCK within time" begins.
