Miou looks so radiant and youthful she could pass for 30, with a strikingly beautiful appearance. She's been in a five-year relationship and is already engaged. She secretly decided to participate in this shoot to earn money for her wedding fund. This appearance marks her final "fling" before marriage, which brings her a bittersweet sense of emotion. Her sex life with her fiancé has never been particularly remarkable compared to past partners, leaving her with a quiet sense of unease and dissatisfaction—wondering if she's destined for a dull intimate life from now on. She may never again experience the thrill of being with a skilled lover, and this thought sometimes leaves her feeling melancholy. Since they don't live together yet, she often spends her alone time drinking and masturbating. When asked if she'll still be able to enjoy sex during the day after marriage, she explained that living in a small urban apartment makes it difficult to keep extra items. The sex toys she's used with previous boyfriends are seen by her current partner as "vulgar," so even though she wants to use them, she can't bring herself to suggest it. This might be her last chance to be with a professional. She wants to be thoroughly pleasured, but at her own request, penetration is off-limits—going too far might turn this into a different kind of release altogether, so the shoot will follow standard guidelines. However, blowjob scenes are permitted. For this shoot, they've prepared a male performer with an unusually thick cock—knowing that women usually find it painful during penetration—but since only oral is involved, she can fully indulge in the experience.
