On the day her husband left for a training trip, his coworker suddenly appeared at her door. The man claimed her husband was having an affair with a client's wife, leaving Kaoru Kira shocked and confused. But it quickly became clear this was no joke. In order to prevent her husband from being fired, Kaoru was forced to surrender her pure body. She repeatedly refused and tried to escape, but as the coworker's fingers teased her intimate areas, overwhelmed her with deep, passionate kisses, and thrust his tongue deep into her pussy, she lost all reason, writhing her hips in surrender. For three nights while her husband was away, Kaoru was repeatedly seduced, drowning in pleasure again and again. This pleasure slowly transformed her. And when her husband returned, Kaoru had already begun craving that pleasure herself.
