Reiko, 37 years old, married for 10 years. What once started as a joyful married life has now completely lost its freshness and excitement. Sex with her husband has become almost non-existent—he ignores her advances, and their daily life resembles an in-house separation. Realizing she needs romance to maintain her beauty and youth, she begins seeking new thrills. It starts with breathy, passionate kisses. When her groin is touched, her legs tremble uncontrollably, making it hard to even stand. Moving to the bed, she's brought to orgasm with cunnilingus and fingering, then overwhelmed by deep, skillful blowjobs that make her tongue dance. Penetration in missionary position excites her intensely, making her body shake as she climaxes. In positions like bent-knee, side-by-side, and finally doggystyle, she cries out, "No—! I'm coming—!" yet is completely consumed by irresistible pleasure.
