Once, me and my wife were having another couple as friends.They had an issue with the man's fertility and they could not have a baby.Also after our wives talked about it,she told my wife that they do not want a random sperm donor,but someone who they know.She also told my wife that she wanted to fuck other men,but also that her husband was vaguely suggesting so.Wife told her that she is fuxking anyone she wants and that we are excellent,because it works for us and she was excited.
Also, she told my wife,after some days, that if we were ok to have unprotected sex,all of us and we agreed.The thing was that they wanted me to get her pregnant.
After I fucked her and he saw me cum in her pussy he started crying.And he left.Sad...
I took some more rides on his wife while my wife pegging me.
Our way of life is not for all...So yes,there will be regrets.
