OBA-268 A married woman named Ikumi Kondou invites her mistress over to have sex when her husband is away.

One Sunday, my husband left home with his son, Susumu, on the news that a horse that had become a single owner was making its debut at the racetrack. It was Ikumi's saffle, Tadakazu, who came to the house at the same time. Until her husband came home today, I thought that I could have sex with Tadakazu without worrying, and Ikumi's crotch was already wet. And the two exchange a warm kiss as greetings. From that moment, the two people's "time limit unlimited FUCK" began.
