I (35M) have two kids with my wife (31F) and they are the light of my life. I would love to have more kids and my wife knows this, but with our financial situation it is fairly unlikely, and my wife doesn't love the idea of having more kids after turning 30.

Her best friend is 25F. They grew up together as their parents were best friends. Although there is some age between them they really are absolute best friends, like sisters really. They tell each other everything. I get along really well with the friend too, whenever she comes over we end up chatting for ages because we have really common interests. Sometimes we joke that if I hadn't met my wife first, we might have ended up together.

The best friend was telling my wife about how she is ready for kids, but can't seem to find a suitable man to settle down with. They both go on about how there is a man drought and how lucky my wife was to find me, a husband who loves being a dad, caring for his kids and living a quiet life where we dedicate ourselves to our family.

My wife came to me this morning with an idea. She said she loves me so much and wishes she could give me more children, but that it's probably not right for us moving forward. However she has talked it over with her best friend and they are open to the idea of me fathering children for the best friend. Although my wife is a little apprehensive sharing me with someone, she thinks this is the best way to help me realise my dream of being a father again, and would solve her best friend's challenge of finding a suitable man. The best friend has said to my wife many times what a great dad she thinks I am and how lucky she would be to find someone like me to give her a baby.

The best friend has said she only wants natural conception, so we would have to have sex probably quite a few times to get her pregnant. When my wife mentioned this I asked how she feels and she said she was a bit anxious about it. When I asked what would make her feel better, she said she might feel better if she was involved in the act. I nearly fell off my chair!

Basically it seems my wife wants to help me get her beat friend pregnant, naturally. I've asked what this might involve and she said he would like to be our intermediary. When I asked what this means exactly and she began describing how she would like to get us both "warmed up" and "ready to make a baby." From what she described she wants me to be inside her nearly to the point of climax while one or both of us is making her best friend orgasm. Then once I'm close to finishing, she wants me to pull out and ejaculate inside her best friend.

It all sounds very hot and fun to me but I am a little nervous to say the least.

Let me know if I should take this opportunity and if so I can describe how we go.
