I have a friend- her name in this story will be Maggie, because I'd feel strange using her real name. One night my wife and I were out having some cocktails with her and her new husband. The evening was going well- we hopped a few bars and ended up at a strip club. Out of the blue, and when we happened to be alone for a few minutes, Maggie asked me if I knew what friends with benefits was. I smiled, though I was not ready for a question like that, and said of course I do. Just then, her husband came back and we said nothing more about it that night. But it sure got me thinking.
Well, soon her husband's true nature began to show, and Maggie showed up at my doorstep battered and bruised by him. She came to me looking for comfort and protection, so there was no way I was going to pursue any FWB course of action- it just didn't feel right. It wasn't long before they divorced. When the smoke cleared, and life was back to normal, I brought up that old question she asked me. She was dating again, but she smiled and we talked. I said I loved the scenario where I could be called on to orally please her at her whim (if I was free to do so at the time). She agreed that it might be a very workable relationship!
On my way home from work one day, I got my first summons :) So I swung by, rang the bell, and as the door swung open, my eyes feasted on Maggie in a black negligee and crotchless panties. She was obviously ready for action!
