After 14 years of marriage, Shizuka felt happy with her life alongside her kind husband, working together and enjoying financial stability. There was only one thing that bothered her: her husband always used a condom during sex. "Such a thin piece of rubber... yet such a thick piece of rubber. There's a world of difference in pleasure with or without it." Shizuka, on her husband's business trip, decides to dip her toes into the world of dating apps, intending just a one-time fling. To her surprise, the man who appears is her coworker's husband. Both are taken aback, and while they're killing time with drinks, they cross the line. Shizuka, overwhelmed by the pleasure of a raw dick after so long, unleashes her pent-up lust.
