So - again, I cut the cards. Nick cut the cards. Viki cut the cards. Yes! Viki and I were paired. The third cut Luci cut the cards and she and Nick were paired. My nerves were rolling. I could hardly believe we were actually gonna do this. I was then, and still am, very shocked that this started without much prior discussion. Luci and I hadn't really talked about this, directly.
The thing is, Mark had made his lust for both Viki and Luci well known. Luci and I had had many talks about what sexual adventures could happen if we invited him over one evening. So a wife-swap wasn't totally out of the question, but, it wasn't something we specifically discussed, either.
Anyway, there was only one bed in the apartment. Luci and Nick stayed in the living room on the couch while Viki and I went into the bedroom. We kissed and made out for a while. This was the first 'other' woman I'd been with in two years. It was very different to me. Her tits were smaller and much firmer than Luci's. I loved, absolutely LOVED sucking and nibbling on them. I fingered her pussy and clit while I sucked and nibbled on her tits. I don't know if she would have gone down on me - but, I didn't want that. I was too turned on and knew I would come quickly. I made damn sure she came before I made my move to fuck her. I'd love to say we fucked for a long time. But, the reality is that it was over pretty quickly. I'd been staring at her naked body for some time already and was on the edge before we even got to the bed.
Meanwhile, we could hear Luci and Nick in the other room. Apparently, he had better staying power than I did. (I confirmed later with Luci that this was the case.)
We four repeated this type of event a few times until both couples decided it was time to start a family. At that point, we stopped playing.
Fast forward several years. Luci and I have kids and we are reassigned to the base where Mark is stationed. We had a one-off threesome with him at his home while we were stationed there. Luci LOVED this. She had clearly missed 'other' cock.
About two years later, we were at a new base. Luci had gone back to college to get her degree. She met this young man named Adam in one of her general studies classes. Adam was 18 (or maybe just turned 19) and had a messed up home situation. I'll be honest, here. I don't know how Luci and Adam got to discussing his situation. She was typically outgoing, though so it may have been innocent. It may also have been a desire on her part to pursue this young man. We were late 20's. He was 18/19. He had longish dirty-blond hair and was fit, well, slender, but fit.
Anyway, we had him over to the house many times for games, hanging out and what have you. He came to dinner many times. He was good with the kids. (Yes, we had two elementary-school aged kids at home.)
Two things happened close together. Adam's home situation got worse - much worse. Luci's work schedule changed. We needed someone to be at the house early mornings between the time I had to leave for the base and she got off work. Adam really needed a new place to stay.
After much discussion, we all decided the thing to do was for Adam to move in with us. We had a townhouse with the kids' bedrooms on the main floor and a large family room and the master bedroom in the mostly-finished basement. Short term, Adam would make his room in the family room. This lead to the main events of this story.
One night, several weeks after Adam moved in, Luci and I were playing in our bed. The bedroom door was partially open. Luci kept whispering for me to, "Stop, Adam might hear us." I was persistent. I had her night-shirt raised to her armpits and was nibbling on her tits. I had my hand in her panties and was playing with her pussy. I was not trying to get her off, yet. I was just trying to get her horny. She was getting worked up. She pulled my face up and kissed me and told me one more time, "Stop, Adam might hear us. The door is partway open."
I told her, "I'll bet he'd love to be invited."
She asked if I was serious. I said, "Yes, I'm serious. I think it would be hot as fuck if you went to him, and enticed him to join us in bed. Remember Mark?"
She asked several times if I was serious. She didn't seem to want to believe me. I placed her hand on my rock-hard cock and told her, "See how hard just the thought is making me?"
