I've had quite a few 3-somes, but never actually owned a pair of crotchless leather panties. Not into all that bondage gear, my experiences were spur of the moment, so there was never time to slip into something less comfortable!
Chucked all that carry on now anyway, it was getting crazy, there wasn't a female friend of mine that I didn't try to lure into bed with me and my boyfriend after being out clubbing, sometimes was very selfish and didn't think how awkward they felt, so enough was enough.
I only ridiculed this pair of swingers (the ones that started this thread) because advertising for it is tacky as hell. Either that or maybe they've worked their way through all their friends too and this is the only option they have left.
So come on then - who else has been part of more than 2 in a bed??
