We have been swinging for many years and I was quite used to seeing my wife being fucked by other men - and loving it - but hadn't seen her being GB'd.
One night she got into the sex-swing in our swinger club and I fucked her. There was another man there, and after I had cum he put a condom on and went straight in. That had happened several times before, but on this occasion there were a few more men around. They started gathering around Rose, kissing her and feeling her tits, and she reached out and held a couple of cocks.
When new man number one had cum, another man went straight in. He'd already put a condom on and couple of other men had got hard and condomed-up too. Man number two fucked her hard and had his cum, then man number three went in. This repeated itself a couple of times more.
Rose was totally "in the zone" and away on a cloud of sexual bliss. She didn't cum with each man but had a few nice orgasms. In total, she had five men, all strangers, plus me, before she came back to reality and got out of the swing. She could have had more if she'd stayed.
We went to the bar and had a drink. Rose was a bit stunned by it all but very happy, and asked how many men she'd had. She'd known men were changing but hadn't kept count. When I said "five plus me" she was amazed, shocked and a bit ashamed. I said it was fine, I'd enjoyed watching.
Since then it has become one of her regular club 'things' but she still can't keep count! Mostly it's in the swing but sometimes she's in a public playroom. I like to watch but also need to be there to make sure all the men use condoms - we've had a few try bareback.
Her 'record' was eight men, but she usually just has three or four one after another. Plus more men when we do swaps with other couples.
It's something every woman should try at least once!
