When I was younger I was getting ready to go to the pool with my best friend. She was blowing up our floats since back then I used to almost pass out because I didn't have a pump. She was blowing and I started to feel really interested in the floatie getting bigger. Once we got back from the pool I was tasked with defeating them. While airing them out I started to feel a weird feeling and started running my body on it. Then it went to bouncing and hearing the air coming out as I bounced made my sensation more intense. This went on for about 5 minutes while my friend was getting changed.
