So, we're a swinger couple. At the time, we where 36M&39F.

A few years prior, we changed swimming schools, and one of the kids had this young (22F) teacher. First thing we both noticed was her near perfect ass.

Over the next 18 months, the wife befriended her. They both are flirty people, to the point I asked the wife to back off in case another parent complained.

She was invited to our house-warming party and the kids birthday party. Two of our male friends tried to chat her up, which was hilarious, so out of their league (and ours, so we thought). After the birthday party, the wife confided to her that we'd played with the the boys and other guests at the party.

A month later, she got invited to her 24th birthday. The night ended with our friend flashing her tits at my wife, and making a plan to come have some girl on girl time.

The night came, starting with some drunk 'never have I ever'. I left to go to the bathroom, only return to find them all over each other, hands down each other's pants.

A shower ensued, and multiple orgasms where had. Later I was invited to join in, however our friends period had restarted, so no pussy for me. But plenty of deep throating, and I finished fucking my wife whilst French kissing our friend.

The night ended with us watching her in our shower, getting herself off at least ten more times.

Needless to say, another date night was arranged for a few weeks time when both ladies would be available...
