It's been three years since I lost my ex-husband. I've managed to get by with my stepson Minoru. But now I've met someone I love. He's the manager of the store where I work part-time, and I'm getting remarried soon. Meanwhile, my relationship with Minoru has continued since the night I told him I was getting remarried. And today, my son came home earlier than my husband, and we were having an affair in the kitchen... The remarried husband witnesses the daily sexual act between mother and son. His twisted 'tastes' will later take an unexpected turn to attack the mother and son...
