My Sis-in-law

My name is Leon; I am 40 years of age, of Indian origin now settled in Melbourne ?? Australia with my wife Patricia. We are happily married for the last 13 years and have an active and full sex-life. I have always been attracted to my wife's younger sister, Sonia, and have fantasized about her in my solo sessions. Last month out of the blue we received a phone call that Sonia and her husband were coming over to spend about a week with us and from then on I have been in a state of constant excitement thinking of Sonia being in so close proximity to me. My wife and I went to the airport to pick them up. Sonia had put on some weight but she was still the woman of my dreams. I got a big erection just hugging her at the airport. Our house had one common bathroom with 2 doors one from our bedroom and the other from the hall. We never had any latches on these doors. The first 3 days went off so quickly, the only thing I could do was every day I would take a bath only after Sonia had taken hers. I would then rush in to the bath hunt for her panties and then stroke my throbbing cock till I came all over those sexy undies.

One Saturday evening all four of us decided to go to the nearby Pub for a couple of beers. We had been drinking for more than an hour, when I realized that I better run to my car to charge my mobile since it was on the verge of dying. As I stood up, Sonia joined me and asked me for direction to the restroom. I showed her the way and walked outside the Pub towards the parking lot. I was surprised to see Sonia following me. She told me that there a long queue at the restroom and she could not wait for so long. I was not sure what to do, it was very dark in the parking lot and there were many cars parked close to each other. I told her if it Ok with her she can relieve herself between 2 cars. I expected her to go to the next row and pee, but instead she told me to look towards the entrance of the parking lot, and started to unzip her jeans, although my back was turned to her I could hear the piss rushing out of her and the sound made me rock hard, I could have come in my trousers but at that precise moment Sonia asked me to get her a tissue from the car. I handed her the tissue as she stood up and wiped herself with it. I got a good glimpse of her shapely ass. How I wished I could have licked her dry. We both were very quite on our way back, all she said was she could not control any longer and felt much relived now. Once we were back in the Pub, I was expecting her to tell the others about her peeing experience, she did not utter a word and I also kept quiet. After a while I excused myself to go back to the car to get my mobile, I rushed to the same spot where Sonia had peed, I searched for the tissue she had used to wipe her pussy. Once I got it I jumped in to the car and with the tissue on my nostrils I pulled the zipper apart to release my throbbing cock. It did not take even a few second for me to shoot a wad all over the dashboard. The night I fucked my wife like crazy and the poor woman thought that all the drinks and the film afterwards had made me so horny. The next 4 days was also very exiting will tell you that story later.
