we started swinging way back in the 70's with couples, and for ages we held orgies every couple of weeks, most times 6 or 7 couples would all get naked and fuck one another, some orgies were bigger,
then we also moved onto bi guys group fucks, at first just me meeting 5 or 6 guys to use my ass as their play toy, then i took my wife along and we both got fucked in all holes by them all, soon we had more guys join in too,was always good fun seeing her being fucked by lots of guys, and every one who came along enjoyed it too,
we have both been gang banged too, my best was about a dozen guys, but my wife out did me by far, one of her reg boy friends set her up and got some 50 or so of his workers to fuck her in a motel for some 14 hours, I missed that but when she told me about it she was so horny and had loved it all,
ever swinger must try group sex at least once, and ladies you have to try more than one cock at the same time too, never met a lady who didn't enjoy being fucked by 2 or more guys once she got going,
