I was just at the pool and feeling horny all day. I couldn't do anything about it at the pool but there's a gym upstairs that's usually not too busy during the day so I decided to check it out. I saw a couple leaving just as I got there, and then I had the place to myself. I needed to cum so badly so I went into the change room and started to use my fingers on my pussy. It felt so amazing and I wanted to cum SO BADLY. Within a couple minutes I was building myself up to a much needed orgasm that took over my entire body! I'm glad I didn't get caught!
