I just finished cumming on this watermelon (in "Inflating, Humping, and Cumming on 24" Inflatable Watermelon Sprinkler"), and now I want to see just how much more air I can get into it. I inflate it more by mouth until it gets really difficult to inflate anymore. Then I sit on it and bounce, and actually bust a hole in one of the seams from my bouncing booty! My first successful inflatable sit to pop!!! I bounce on it as it loses its air under me, and grind on it as it loses its last bits of air.
