During her husband's business trip, she impulsively downloads a dating app, just to see what happens. The man she matches with turns out to be the husband of her coworker. With time on their hands, they meet for drinks and grow increasingly intimate. Soon, they cross the line. Experiencing unprotected sex for the first time in years, Shiori's pent-up lust erupts in a powerful creampie release, igniting unexpected emotions and desires.
