The father-in-law decided to impregnate his son. Although the intelligent Ryoko initially resisted fiercely, her instincts eventually kicked in, and she became a "female" in front of her father-in-law. Unfortunately, this scene was discovered by her husband. What did he do in his excitement? What was the final outcome?
