A thirty-something woman whose body is now more curvaceous than when she was in her twenties, and whose feminine charm and pleasure have only increased with it. We bring you the tense moment when she first exposes her body in front of the camera! Perhaps because she was raised in a strict family, Yoshino Tsubaki had no interest in sex, but after she turned thirty, she suddenly started to feel good, and she actively seeks out men and gets very excited about her first creampie. Amamiya Naru Amamiya, who is extremely embarrassed, is actually a genuine perverted wife who loves dick and has even given a blowjob on a bullet train, and her climax with a squirting orgasm is a spectacular sight! A documentary of four thirty-something wives stripping off for the first time, with both joy and embarrassment.
