I have shared my wife and been a third for couples. She has been with two other men.

The first time she brought up meeting a guy she was talking to on a swingers site or app. It wasnt someone I would pick so I wasnt even that into it but I felt like I had to fuck her before she left and after. Not that I was so into it but I wanted my cum inside her when she met him. I dont know why.

The other time was a little spontaneous and I fucked her with a guy I knew from the gym.

The times I have been a third I would want to do oral with the wife but I didnt because I dont want to eat some guys cum and it feels rude to ask or ask them not to before so I just didnt do it. But the idea of the wife making the husband wait to tease him is hot. Even the idea of mine doing it but I dont know if I would let her if she was going out and I wouldnt be there. How are others with this?
