27-year-old Asakura Sana. A refined beauty who looks stunning in a pure white dress, her short haircut is strikingly beautiful, and her calm, composed speech exudes an intelligent aura. Before marriage, she worked as a piano instructor and has loved classical piano since childhood. She is now a full-time housewife enjoying a peaceful home life. Though her marriage to an older husband has been smooth and stable, she's troubled by the decreasing frequency of sex due to his busy work schedule. On average, they have sex only once or twice a month, and sometimes not at all. This has led her to desire more sexual experiences, prompting her to respond to an online recruitment. Having lived a pure and serious life, she has never had a casual relationship or sex with any man outside of a committed partnership. As a result, she feels anxious about her lack of experience and worries she's missing out on an important part of life. Being already married, the chance for new romantic encounters is nearly impossible. Let's show her what real sex is like. With her cute facial features and F-cup big tits, we want to give her a completely new experience.
