My wife's best friend

No Names used to protect the horny.
I didn't cheat on my wife with her best friend, she asked me to fuck her best friend to get her pregnant. I'm 38 and my wife is 34 and her best friend is 36 and a lesbian till before the request to fuck by my wife. Her friend was in a long-term relationship with a woman who decided she wanted pastures new. Depressed and wishing she had a child; my wife was comforting her after the breakup. My wife was pregnant with third child at the time, which is probably why her friend thought about having her own child. Anyway, my wife decided to help have a child, her friend had a good career and lived right next door us. Which made my wife think about me being the father. The reason told me was her friend could've the child and still have her career and she my wife would look after the child while she worked, and we would have a family connection. I asked what your friend thinks about all this, and she replied I haven't asked her yet. I want your agreement before asking her, I didn't think her friend would agree and so said Okay. Her friend a little overweight I thought was hardcore lesbian and wouldn't want a man in bed with her. But I was wrong she really wanted a baby and from that week onwards she joined me and my wife in our bed and still after getting pregnant as well. I had another son with my wife making 3 boys and a girl. My lesbian neighbor and wife best friend had a girl last month and is still sleeping with us. They are talking about another child already, I'm willing as I'm getting extra sex from my wife and even get the odd blowjob from her best friend.
