Many years ago on a different site, a lady friend I worked with and who we socialised with, recognised the dog in the background of one of our pictures. A couple of tentative messages went backwards and forwards but I didn't know initially who it was. Once she was sure she had the right people, I got an email, not via the site, this obviously gave away who she was. We had a few exchanges and the bottom line was she was going a little short at home and would like some friends to go out with, ideally to try a club. Although the wife was not really interested in going to a club, she decided that she should go and see what it was like and we could take our lady friend with us.
We decided on the night and our friend quite happily made her arrangements to go out with us for dinner and would more than likely stay over as there would almost certainly be some alcohol. We booked a table for dinner, we enjoyed the meal and then made our way to the club, we were a bit on the early side, so it wasn't very busy and only one other couples and a number of single guys. A couple of hello's were exchanged, but there didn't seem to be any spark. Then our friend, realised she had left her coat back at the restaurant. I offered to go and retrieve it and left the two ladies together. As soon as I was gone the guys started coming on a bit strong. Within 15 minutes I was back coat rescued. Both ladies had decided that the clubs were not for them, and could they please leave.
I had been looking forward to the evening and had hoped that there would be some playtime for me at the club as well, but alas. Back home our friend asked if we had any porn to watch, so maybe I was going to get some fun anyway. So I sat like a dog with a bone, between the two ladies and started stroking legs either side of me. It wasn't long before we made our way upstairs. The evening went well with lots of naked flesh a little bi play from the ladies and my best efforts were rewarded. There was no awkwardness the following morning but the wife decided that ladies were not her thing.
Thinking that this might then be a one time only deal with my friend, she was thanked by us both and left to go home. Some weeks later I messaged her to see how she was. She had enjoyed the evening and would like to visit again. So I asked the wife if this would be okay and was surprised by her response, "why don't you ask her round while I'm at work". I checked with our friend and she was also happy with the arrangement.
So for a good few years now although we still go out socially with our friend, me being loaned out is never discussed openly. My wife and our friend have been communicating via hand written messages, one left for our friend by my wife as she leaves for work on the days a visit is planned and one left by our friend as she leaves to go home. I am not privy to the content of these messages, nor do I wish to be.
