Mrs. Hitomi, a slightly mature married woman, is having an affair with another man because her husband won't be her nighttime partner. She wants children, but with no intimacy with her husband, it seems hopeless. So, she came up with a crazy plan: to have a child with her lover! Both her husband and her lover are type A, so she thinks she won't get caught! And since she's so naive, she figures it's fine to have unprotected sex with her lover, making her quite the plaything for him!
