Threesome Advice Please?

Ivy

UPDATE: UPDATE: So... It happened! The girl and I decided to camp out Saturday, Sunday, and Monday. We invited my fiancé and he got there late Saturday night. We were all just chilling.

Our plan was to get high first, but we didn't have access to some weed until Sunday afternoon, so... We had a threesome Saturday night/morning and then later Sunday afternoon/night. Early Monday morning we kept it up too.

There was kissing, touching, blowjobs, sucking on boobs, fingering, handjobs, etc.

At one point the girl and I were making out and my fiancé was fingering the both of us. It was suuuupppperrrr sexxy

All in all, I don't regret it and it was an amazing weekend 💕

ORIGINAL POST: So... I need advice. There's an opportunity for my fiancé and I to have a threesome with one of my close female friends. There are rules such as; all can kiss and touch, he can't eat her out, she can give him a blowjob, his dick doesn't touch her pussy, I can finger her, etc. We have spoken with her about it loosely and the only concern is what would happen to her and I's relationship. Is it worth it to go through with this? She and i have made out and touched a little while we were both high and that went well. I don't know what to do... I think it would be really fun and nice, but yeah, I'm not sure what it's worth... If you have any advice, let me know!
