Mary grows increasingly frustrated with her husband, who uses his busy schedule as an excuse to avoid sex. At the hospital, she is diagnosed with low sperm count; while pregnancy isn't impossible, it's unlikely without a miracle. One day, her father-in-law comes to visit Tokyo and stays over. Since he is also looking forward to having a grandchild, Mary can't bring herself to share her troubles. By chance, her father-in-law finds out about his son's situation and spikes Mary's food with an aphrodisiac. He asks her if she truly enjoys sex with his son. Taking responsibility as a parent, he rapes Mary and ejaculates inside her. Due to the repeated aphrodisiac torment from her father-in-law, Mary becomes aroused and starts to desire him instead of her husband.
