You wrote that you have a wife to offer. I am ready to mount her while you watch or in your absence.
If your are interested I am available to assist her with pregnancy.

I introduced my wife to wife swapping several years ago during out honeymoon in Holland. It happened in Amsterdam's Red-light District and that evening she had 7 clients (see 3.rd picture): https://disk.yandex.ru/d/AUQarNN5lpr79w My wife is now 30, she is not on birth control, and I would love her to be mounted by another man with a high potency and high sperm count. I would love the risk in reality.
