It all happened for 20 minutes and by the time and I was dead still pretending I was sleeping. It was all a strange experience and I was not 100 % sur... that what happened afterwards both of them went to the washroom naked and I saw both my parents naked going out of the room.This incident changed my life it brought some excitement and lot of questions about what happened. Then after few weeks when we all were sleeping then suddenly my sister said that she had some itching in her back and her. I am a constant reader of ISS and since a very long time I was thinking a lot to share my experiences of sex life with the readers of ISS but was not sure enough that whether I should do it or not. But at last I decided to do so & here I am with one of mine most exotic & unexpected experience.Let me tell you that I am 32 & married, working with an IT MNC company on a senior level. People do say that I am handsome & can give complex to anyone. My wife also says the same & is very happy to have. I just shook my head at that.By noon we were through the hills and out on the wide expanse that formed much of the left hand side of the lake. The ground was covered in short grass, clover, wild flowers, and the occasional clump of brush. To my eye it looked to be at least several hundred acres. It stretched for a couple of miles in one direction and several miles in the other.We stopped about midday near the shores of the lake. Where we were the shoreline was quite open. There were a few. "What's wrong?" he asked with concern, thinking he had failed her, "didn't you like it?" Oh no Frank, you couldn't be more wrong. I'm sorry I am crying, but it was just so good, even better than I ever imagined. I am so glad I was able to have you for my first lover" she cried to him, as she brought her hands to his face and kissed him gently, unlocking her legs from around him and laying with them either side of him.Now Frank was able to roll them both onto their sides. He managed to stay.
