My wife wants to have a baby from our friend. ⇐ General

[Guest]

I seem to be repeating myself. But the topic is very delicate for me. Maybe someone had a similar situation. Here, as they say, and want and prick.
On the one hand, our friend loves my wife, and he is pleasant to me, and I let them be together, spend the weekend, fly to resorts, and even the three of us are together. A friend honestly says that his secret dream is that my wife would give birth to a child from him. And the wife honestly speaks about her desire, that since we already have a child with her, she would very much like to give birth to our second child from our friend, and this would be fair as a sign of his love for her.
I still have a mess in my head. It's one thing just to have sex with another man, and another thing - a child from him. Although in the depths of my sinful soul I understand that as soon as their sex is pleasant to me, then I must be mentally prepared for the fact that as a result of their sex a child from him may turn out, and I will have to accept this child as my own. Why else would I let them have sex. It is prickly that it is not known how, years later, our friend will behave: would he want to tell the truth to the child, who is his real father? The most important thing is how it can affect the psyche of the child.
