It's been three years since my previous husband passed away. My step-son Toma and I have been working together to somehow make a living. But there is someone I love now. He's the manager at my part-time job, and I'll be remarrying him soon. Despite that, my sexual encounters with Toma have continued since the night I told him about my remarriage. And today, while I was having an affair with my son in the kitchen, who returned home earlier than my husband... My new husband witnesses the daily sexual acts between mother and son. His twisted 'preference' will then strike the mother and son in an unexpected turn of events...
