[AaaBeeCeeDee]

Hi all, been a silent reader for a bit but this time I have some questions and need some guidance and opinions, I'll try to keep it as short as possible

One of my good friend, let's call him A, come across a nude of my girlfriend taken while on vacation. She told me that since then, A had been complimenting her on her body and asked her to be his long term fwb behind my back

Normally I'd be disgusted that a friend could do that to me, but my girlfriend and I had been throwing the idea of having a threesome around

So I told my girlfriend to entertain him, starting with a handjob, moving on to fucks and giving him blowjobs sooner or later, all the while acting like I have no idea what's going on

There are a few things I'm hoping to get out of this namely (either 1)

1. Negotiate a foursome with A and his girlfriend
2. Turn this into a long term thing and have my girlfriend please both of us
3. Have my girlfriend meet up with him long term while keeping it secret from me

None of these actually happened yet, clearly we are planning towards it but my girlfriend and I have also been getting cold feet every now and then and find it hard to proceed despite as much as we want it

She's also mentioned that it might be better to swing with strangers instead of close buddies

Opinions?

Advice?
