She was looking quite sexy in the nightgown and I was wearing blue jeans and t-shirt. We were also watching movie on cable as talking to each other. S...e shifted the topic to my future plans and about marriage. I told her no plans for marriage at present since I had settle in my professional life however any good proposal came for girl having qualities like to you, I will consider the things. She asked what qualities I like about her. I told her that she is well educated, settled , working,. She agreed that things had been pretty boring in the bedroom of late and said, “I will go this one time and see what happens.” I was truly excited as all kinds of thoughts began to consume my mind. I really had no idea how this was all going to play out, but it certainly left me in a state of high arousal. We decided that coming weekend we would check this place out. That night my wife and I had an agreement between us as we left. I gave her freedom to do whatever she liked. This included going. I sat back and just relaxed and let her do her thing.She just kept taking me down her throat and started to make quiet gagging sounds. The feeling was so good that I got lost in my place. I couldn’t believe this girl was sucking me off in a public library and it felt this good. I kept my eyes closed and told her that I was about to cum. She pulled her mouth off and started to jack me off fast. In a few seconds I came and she put her mouth down and started to swallow it. My body tensed as I felt. So we sitting there naked at the table the three of us with my friends wife sleeping upstairs, and big trouble if she caught us like this. I sensed that we were all getting a bit horny with this nakedness so on my wife’s next forfeit I said that she must fondle my friend dick. By this time she had no hesitation and stood up walked to his chair pressing her boobs in his face while she reached down and fondled is dick which was obviously already rock hard, and he was suckingon the nipple in his.
