The Storm

We walked out to the pool and dropped our towels and dove right in. My sister was wearing her pale orange one piece suit. The beautiful thing about it was when wet she just as well be nude. I could see every bit of her breast and could count every hair on her pussy.  We start splashing around and my hardness was pretty obvious. I stuck straight up to the top of my black Speedo, that was last years suit also. I guess I splashed some water up her nose because she went to the side of the pool a lifted herself up and was coughing.  With her perfect ass above the water in her see through swim suit, I was really having a hard time keeping my penis in my suit. The more I tried to get it under control the worse ( or better ) I made it. It started to get really dark as the storm clouds rolled in. My sister jump from the pool and grabbed her towel and yelled " tornado, we need to get to the basement!" I jumped out of the pool and ran following her through the house and into the basement. We ran down the stairs and into the laundry room. Breathing really hard she said we needed to get out of the bathing suits before our parents got home. Never being the shy one, she pulled her suit down and slowly was peeling it from her wet skin. Really rolling it off her body. I stood there watching. I have seen her many times naked but for some reason this was so sexy to me. She suddenly stopped and told me I needed to change also. She reached out and pulled down on my shorts. My penis, being really hard, got caught in my shorts and sprung up and slapped my belly when it was finally free.She thought this was funny as she giggled and kept pulling it down so it would slap back up. ( to be young again ). I guess from the look on my face she could tell I was enjoying the feeling. She stepped closer and started to slowly stroke my dick. Long and slow as she looked at my face and back down to my dick. I reached out with my left hand and started playing with her ass. She really had the best ass I have ever seen. With my right hand I started to finger her. The more excited she became the faster and firmer her hand became. She put her head on my shoulder and kissed my neck. I almost immediately started cumming on her pussy and down her leg. She had stopped so I had to take hold of penis and milk it dry. She watched as I finished the job she started. We hurried up and cleaned up with some dirty laundry and hung our suits on the line to dry. After getting dressed we went up stairs as if nothing strange had happened. When our parents got home, as luck would have it, Mom decided to do some laundry and found our wet swimming suits. We were grounded for two weeks. Two weeks to have my sister and best friend all to myself. Not much of a punishment :-)
