This slutty bitch, Sumire Mihara, ALDN-238

The father-in-law was deeply troubled, wondering why his son couldn't inherit his important bloodline. One day, he accidentally witnessed his son and his wife engaging in sexual intercourse, and the adoptive father became convinced that his son's sexual ability was very low. The father-in-law decided to impregnate his son. Although the clever girl initially resisted fiercely, her instincts eventually kicked in, and she became "female" in front of her father-in-law. Unfortunately, the husband discovered this scene. What did he do in his excitement? And what was the final outcome?
