I immediately became aware of what I was doing, how instinctively I was acting, like a predator in front of a defenseless prey, it was irrational to a...t that way and I got scared just thinking about the catastrophe that would happen at home. I released my sex and went to take a cold shower to calm my basic instincts.I spent about two days tormenting myself, a part of me doing everything possible to avoid looking at her in any other way than as the little girl of the house, my wife's little. I take a quick look around, the neighborhood is still quiet so I carefully unzip my pants and remove my swollen member. As soon as she sees it the pace of the her pussy fucking speeds up and after ten or so repetitive thrusts of the vibrator she pulls it out revealing her open pussy. At the same instant that a deep moan comes out of her mouth a stream of juices shoot from her pussy across the room nearly hitting the screen I am up against.I begin to stroke my cock feverishly as she put the. I put my hand under her top so I could touch her already hard nipples. She was very aroused already, a situation created by being outdoors, with the possibility of being seen.We kissed and played for a few minutes, then continued down the path. In a short while, we found the stream. Upstream about 200 yards we could see what appeared to be an abandoned shack of some sort. It was about 50 feet from the path, so we went to check it out. It was made of stone, but all that was left standing. This caused me some concern because she might have seen Peter and I leaving the social on our way to our little tryst. However nothing was said on the drive home and when we we got back Amanda and I went straight to our room and changed into our night gowns ready for bed. As was the custom before retiring, each of us would go upstairs to say goodnight to Aunty Betty. Amanda had already said goodnight and returned, then I went upstairs, gave Aunty Betty a hug and a kiss and was about to leave.
