If ur so call friend is doing that behind ur back. It really show what kind of person he is. Personally, I would cut all ties with this kind of bastards, let alone let him have a go with my girl.
Furthermore, I'm not sure if he will kiss and tell, go around spreading words that he had fuck ur gf and maybe have some video/photo to proof it?
Ur gf might not even know shes been video.

What makes u so sure that A will even consider shareing his GF? End of the day. U might be the only loose in the relationship. At least ur gf get to be fucked by new tool. But u?

Ur gf is right that swings should preferably be carried with total strangers, there's a reason y the swingers club is called undertable. It suppose to be a secret.

Last but not least, if you are having cold feet and not sure if u wanna do it. I really dun think u are ready.
