The couple living next door, the Mr. and Mrs. Yukina, seem like the ideal couple. They're still very much in love even now. Mrs. Yukina is responsible and good at housework, while her husband is handsome and dedicated to his job. But they also cherish their time together as a couple. Isn't this relationship too perfect? Still, there's one thing that bothers me. How about sex? I want to do the best, most amazing things with you that we've never done before,,, ah, I can't take it anymore. Let me drop by Yukinari's place. Let's all have a good time.
