ALDN-238 This bitch is a lewd beast Sumire Mihara

My father-in-law was worried about why he couldn’t find an important heir…One day, he happened to witness his son and his wife having sex, and he became convinced. That’s right…his son’s ability as a “Han” is low…his father-in-law decides to inseminate in his son’s place. At first, Sumire desperately resists with her rationality, but eventually her instincts awaken and she becomes a “female” in front of her father-in-law. However, her husband witnesses her appearance. What did the enraged husband do? And the ending…?
