Congratulations!! [Suga Hinako] Takara Eizo exclusive actress work! Part (1)!! After 6 years of marriage, 38-year-old Hinako was frustrated that she couldn't have a child. She had a good relationship with her husband, and they had sex on her ovulation day. However, she couldn't get pregnant. One day, Hinako found out that her father-in-law had six children. When she heard this, Hinako thought of a forbidden act. Common sense tells her that it was wrong... However, Hinako desperately wanted a child, so she asked her father-in-law to donate sperm. Moreover, it was a way of donating sperm that was unthinkable by common sense. Her father-in-law, who wanted an heir, decided to respond to Hinako's outrageous request in a businesslike manner. Even though she told herself that it was a businesslike thing to do, the pleasure overflowed. Hinako and her father-in-law desperately resisted the pleasure. And what was the final decision they made...
