A Night with my Sister-in-Law and her Boyfriend

A few years ago my wife and I were newly married. I had taken a job on the west coast. We had moved away from our families in the east. With the new job I was making plenty of money so my wife was able to stay home and enjoy life. As the years past our family started to grow. We now had two girls and wanted very much to move back to where our families were. This presented a problem. We ended up selling our house on the west coast at a substantial loss, due to the market conditions. We decided that we would move in with my wife's parents until we could save enough for a loan on a new home. Luckily they are pretty wealthy and had a large home. My wife has two sisters, she is the oldest. The middle one, Sharon, moved out of the family home a few months back which just made it us and the youngest, Shelly. Sharon was 26 at the time and Shelly was 23. Sharon was the typical east coast party girl, going out to the bars and clubs every weekend and having fun. Shelly was a little more reserved, staying in most nights, although she did have a boyfriend named Cody who didn't live too far and spent most of his time at the family home with Shelly. It was summer when we moved back, and it was a scorcher. Most days the AC ran all day and night. Everyone pretty much hung out by the pool during the day, including my wife's parents. Shelly had fairly pale skin and was always trying to get a good tan, at the same time she did not appreciate tan lines. So there were a lot of skimpy bikinis ...

... being worn around most of the summer. Luckily she could pull it off, she was a 5'7" petite blonde with a small C cup and an ass to die for! Seeing her in a thong bikini was a sight for sore eyes. I really didn't know the family all that well when we moved in so it was a learning experience. I spent most of my time reading outside while everyone was hanging out in the pool, I wasn't much of a swimmer at that time. One day I was home hanging out as usual and Shelly comes in with her boyfriend to go into the hot tub, they walk by and say hi and continued to get in the water. Before I knew it they were all over each other, making out, feeling each other up. I could see from the pool deck that Cody had his hand in her bikini. I just watched, I didn't want to interrupt, I was enjoying the show too much. Finally just as they came up for air Cody's cell phone rings, it was his boss, he had to go back to work on an emergency. He got up out of the pool and was sporting a very hard cock that was easily visible through the thin board shorts. I jumped in the pool to cool off before anyone noticed how hard I was getting. I swam over to the jacuzzi hot tub area and jumped over the wall that separated the two and joined Shelly. You could tell they were both left hanging, he left with a hard-on and her nipples were poking through her padded bikini top. I slid over to her side and asked her how she was doing she responded telling me how horney she was and that she couldn't believe he left her ...
