[Reducing Mosaic]DASS-250 My slender big-breasted wife was taken by my old man and bred. Tachibana Mary

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.
