A couple from Saitama Prefecture accidentally applied through the Warp Entertainment website. They have been married for five years. The wife formerly worked at an SM club, where the husband was a client, leading to their marriage. The wife possesses exceptional skills as an S-type woman, particularly renowned for her mastery in dominating female masochists, and the tattoo she got during that time is said to symbolize her true nature. In their current married life, she insists on calling her husband "Master," a term deeply significant to her. This submission is their first, motivated by a desire to prevent stagnation in their relationship and to showcase her remarkable training techniques.
