[MF] I (very briefly) Fucked My Wife’s Younger Sister….

I’m not writing this under my normal username for obvious reasons….

About 10 years go I went on holiday wife my wife’s family to Thailand for two weeks. Her mother, and her two sisters who are all of Chinese descent. One is married and was 29 at the time. The other was 25 and had a boyfriend who wasn’t present. We stayed in a very nice resort, which had a great lagoon type swimming pool, which had a bar, and split into different sections. Some parts were in view of hotel rooms, but others, near the bar area were hidden away by bushes and trees and a lot more private.

Cutting things short, my wife, and her older sister both managed to get an upset stomach after eating something, and for a couple of days didn’t feel very well, and spent a lot of time in their rooms. I have always got on well with my wife’s youngest sister in a friendly/family type of way, but as she has become older, I had begun to find her quite attractive, but NEVER had any intention of doing anything about it.. She’s around 5’6″ in height, medium in build, with quite a curvy and full figure by asian standards

One evening a week into the holiday the younger sister decided to go for a late swim in the pool. My wife was already asleep, and everyone else just wanted to relax in their rooms,so I decided to join her in the pool. I was surprised how nice she looked in her white tankini. We were the only ones in the entire pool, and we just swam, chatted and messed around. At one point I started fooling around, swimming under her and pulling her legs etc, and she started doing the same to myself. I then swam between her legs, which surprised her and things seemed to be getting a little flirtatious. By this time I had a hard-on, and I was hoping that she wouldn’t notice as I didn’t know what her reaction would be. She started to mess around and her hand accidentally brushed my cock through my swim shorts. She stopped and stood really close to me and started to feel my hard on through my shorts under the water. I was frozen to the spot as it was a total turn on but all so very wrong at the same time. She then said ‘follow me’ and swam to an area behind the bar which was very shallow and out of sight with slightly submerged seat you could sit on. I stood in the water which was just about under waist height unsure what would happen next when she pushed her hand into my shorts and started wanking my cock. We kissed and I slid my had down her bikini bottoms and slowly started fingering her pussy in the water. I felt very turned on, but also felt paranoid in case anyone caught us…. I pulled her bikini bottoms down, and she sat on the side of the pool. I pulled her legs open, and then started to lick out her pussy, all the while we were both trying to listen out in case we were disturbed. I then stood back up, and she gestured for me to pull my shorts down. The pool was just below waist height in this area. She lay back on the pool edge with her legs wide open, and I slowly pushed my cock into her pussy. It felt fantastic, but after literally six thrusts, there was a load of sudden noise, and it was pretty obvious a large rowdy group were coming toward the pool… We panicked, stopped immediately and left the pool. Before going back to our hotel rooms we did speak about trying to meet again for an unrushed sex session but it never happened. My wife’s younger sister was staying in the same room as her mother and there was never another safe opportunity to meet. When we got back to the U.K. my wife’s sister spoke to me about what had happened and said it was a stupid mistake and we should both forget it ever happened. That was over 10 years ago and nothing has happened since. Its the only time I have ever cheated on my wife
