As I grow older my notion or 'erotic fantasy' has changed. More accurately it has become more focused. I know what I really like. Some of my fantasies will forever remain just that, fantasies. Others have been easily filled when they are simply a matter of waiting for the right circumstance. My favorites are the ones where limits are pushed.
I have a wonderful wife that has on occasional indulged my fantasies. She has made some of them reality. At least to the furthest extent that she can. We both, of course, stay faithful to each other. The problem is the notion of what constitutes being unfaithful. I don't feel she is being unfaithful at all when she is making my fantasies real. She is doing it at my direction (and hopefully she is enjoying herself too). Her sense is that she is being unfaithful, even when it is with my blessing. As such she has limits. Let me tell you about my favorite fantasy that she brought to life.
I have long wanted to be in a hot tub and watch my wife with another guy. She would slowly undress in front of us both. If everyone was comfortable, things could proceed from there. My wife and I talked about it for a long time. Once I had spelled out what I wanted to see, all that remained was agreeing on what the limits were. There would be no kissing, or genital contact. Everything else was negotiable.
We posted our intention on various adult classifieds and started to filter through the responses. After a few months we found an ideal candidate. He understood that there were strict rules and limits in place and she could halt things at any moment. He agreed and we set up a time and place.
There is a place in the city that rents private hot-tubs by the hour. My wife and I go there frequently in the cold months. It had always been just the two of us. We met 'Dan' there on a weekday afternoon. We rented the tub and sent my wife in first so she could get ready. That gave Dan and I a chance to talk. As we agreed to beforehand, we had both worn swimsuits underneath our clothing. My wife brought an outfit she was going to wear. After confirming with Dan the rules we had agreed to, we proceeded to our room. Throughout everything that was to come, Dan was completely respectful of the limits we had established.
My wife was already in the water and the lights had been slightly dimmed. Her eyes closed as she was apparently enjoying the warmth. She was wearing a pair of my running shorts and a white tank top. She has really nice tits and the sheer tank-top made them all the more yummy. Dan and I took off our stuff and hung it up. I told him to sit on the side opposite my wife and I took my place in between them.
I had scripted today's encounter beforehand with my wife and Dan separately. I wanted things to proceed very slowly. I enjoy it slow, but taking it slow was to ensure that she dictated the action. I had thought that we would all talk for a while and break the ice. About ten minutes in I wanted my wife to start playing with the edges of her tank top. A little pull here, a little tug there, with an occasional nipple pinch.
