I haven't. It might be fun though. I"m assuming you're referring to more then three persons involved.
I have taken part in a few gangabangs, and to me that means 5 people and up. I've always been the bottom yeah I've always had fun and yes I'd do it again and probably will soon. It's not for everyone though. You really have to be able to let yourself go, especially if you do it sober.
so when u guys cum, do you guys wait til everybody is on the same page or let it fly when you feel like it?
depends on the tops. some get in and get out, hang around watching for a while and go again, some last a really long time and save it up till they can't take it anymore, some don't get off at all. but yeah, most guys just "let it fly"
While I've never been part of a gangbang (or been to one) but seeing a woman getting filled up with cum is HOT, I'd never let my mrs do it though.
I've been the "female" in every group fuck I've taken part in and I can assure you, it is not bad being the one getting fucked.
we have talked about. She hasn't rules it out. but for now we are trying to arrange a MMF sometime after the holidays. this will be our 3rd time and hopefully this one goes great.
