Wife's breeding kink, infertility, and my best friend

This was a while back. We've been married going on 15 years. My wife has a breeding kink for as long as I can remember. A little context, former swinger couple and currently a cuckold/hotwife couple. Long story short at the time I was infertile. We had 2 chidren already but for whatever reason struggling to have a third. After a year and a half of trying I wasn't getting my wife pregnant. My wife wasn't too happy and was sad.

My best friend was over one day and we were talking about it. Then he jokingly said I'll get her pregnant. We laughed but my wife said why not? I looked at her because I could tell she was 100% serious. Also knowing she has a breeding kink. She said yes, get me pregnant. He laughed because he thought she was joking. She said I'm being serious, get me pregnant. We looked at each other and I told him well, I think she's serious. He was in a little shock. She said, basically told him about her breeding fantasy she had and this would be perfect.

We always talked about it but never actually thought it would happen. But for whatever reason it really turned me on to think my best friend getting my wife pregnant. He said he was joking but id she's really serious he would. She said she was serious and then told him my husband cant do it and I want a baby. I said fuck it, go for it. Then we talked for a bit.

They hooked up for like a month about 4 times a week. He ended up actually getting her pregnant. We made an agreement that he wanted no responsibilities and we were fine with it. But my wife couldn't be happier. She fulfilled her ultimate fantasy after years of fantasizing about it. She enjoyed every aspect of knowing another man got her pregnant. She would talk about it how I couldn't do it but he could.

Not going to lie, it was a huge turn on. It all worked out for us and she still talks about it. She's considered doing it again. Which I siad whatever she wants to do. It's been some time since then and we're a bit older. She still has that kink.
