The "Costume Room" is an adult erotic space filled with toys for grown-ups. Using AV gadgets, this series offers real amateur sex without acting—just raw, unfiltered intimacy captured on camera. This time, a couple who have been dating for three months appears. They met at a mixer, and Keiko is the type of woman who devotes herself to her man. Though she was nervous at first during the shoot, especially since it involved her favorite act—pissing—she gradually got into it, and her partner kept saying, "I want to come again." This is a genuine, intimate scene showcasing the pure, natural eroticism of amateurs enjoying adult play.
