This story was really erotic!!! I loved reading this story, Nicole. It sounded like such a thrill. I have a similar story, only it was at the lake on a sunny day, no rain.
A few years ago, before my grandparents sold their mansion at the lake, I was out there for the weekend. We always went boating, and skiing and stuff like that. I decided to go out for a swim in the middle of the lake. I jumped in the boat, headed to the middle of the lake and jumped in. The water felt nice, and I was relaxed. All of a sudden I had thoughts of this girl I really liked, but was too shy to ask her out. I started to get hard, and extremely horny. I pulled my swim trunks off, grabbed a life jacket, and sat in the water, and slowly stroked my hard cock until I couldn't take it slow anymore. I pumped away for about five minutes or so. The feel of the water was awesome, and my arousal was unbearable. I spewed cum all over the water, I don't ever remember ever cumming that much or that hard.
See, I too love the water, sometimes for more than swimming. I am Aquarius, but always loved the water!
Thanks for reading!
