My wife's sister

Brief story.
My wife's 39, almost 40, was afraid she would never be a mother. IVF for a single woman is almost impossible. Going out to find a stranger having sex also comes with risks. My wife decided I should get her sister pregnant by donating sperm. My wife got the sperm and helped her sister insert it. Nothing happened. After several tries, my wife then decided direct insertion was the best option left. So, I was to fuck my sister-in-law to get her pregnant. But the sex was a threesome, including my wife. I enjoyed fucking them both, and they both really enjoyed the threesome also. I did get my sister-in-law pregnant, but the threesomes continued. Why not? We were enjoying ourselves quite a lot.
