Yes, have been off and on for over 20 years now.Are you still swinging? Would love to hear about the first time your wife saw/encouraged/helped you suck a cock.
Posted about that before:
First real experience(aside from youthful truth or dare type stuff) was a foursome at a swinger's club. A woman asked to join my wife and I who were getting busy in a room. After saying yes, she practically dove right in between my wife's legs and started eating her out. A short while later her husband asked to join. He started playing with my wife while his blew me. She started fingering me with the blowjob right away. I gave her a sly smile and said I bet she's good with a strap-on. Then we fucked each other's wives.
In the time between rounds we got to a little chatting and he mentioned that they were adventurous and open to most anything. As things started to heat up I was eating out his wife until she came...then I did it. Just leaned over and took his cock in my mouth and started sucking. I murmured with a mouth full of cock that it was my first time and he said the same. His wife got behind me and started fingering me again but with her hands low at her hips and essentially fucking me with them by thrusting her hips. Eventually he said he wanted to fuck my wife again and I reluctantly released his cock from my mouth as his wife went down on me.
