OBA-201 While her husband is away, the housewife invites her sex friend over to her house and indulges in sex.

It's Saturday, and her son Yuta has been in high spirits since the morning. He's going to the pool with her husband, who's on summer vacation. Chisato, who's planning to stay home alone, is also excited. She's waiting for her "sex friend" to come over while her husband and Yuta are out... Kenji, her sex friend, takes advantage of the opportunity to come over as soon as her husband and Yuta leave. "Let's have lots of sex today!" And so the two begin their "unlimited fucking within the time limit, as many times as you want"...
