Mitsuki Oshima, 38 years old. A self-proclaimed slut wife whose uterus tingles if she doesn't have sex five times a week. The body she trained in swimming and athletics during her student days seems to have improved not only her muscles but also her libido, and she is not satisfied with just her husband, so she spends her free time looking for men on dating sites... "No matter how much I love it, I can't work in the sex industry. I provide service as a job, right? As long as I feel good, that's fine with me (lol)," she says, and today she wants to be completely passive and devote herself to pursuing her own pleasure. Now, let's thoroughly conquer the body of this selfish wife!
