Having been a bachelor into my early thirties I dated a few gals that ended up marrying guy friends of mine. It always gave me a little tingle in my crotch watching a gal get married that I had been with.
Probably the most memorable memory being when two friends of mine from the swinging lifestyle got married. They hosted a party for several of us a few days before the wedding. At the party they told everyone that they were taking a break from the lifestyle and this would be their last night of group fun. She was a real "trooper" that night and made sure she sucked and fucked all of us including going down on the two gals present.
The bride was a real "knockout" - 6' tall, slim, 36C, blonde hair to her waist. I had known her since HS, but I never got to have her until we started swinging together.
I'm hoping they decide to get back into the lifestyle
