OK this one is a little intimate, and not something most girls will show you. I sometimes like to masturbate with a full bladder, it give a nice aching feeling all the way to orgasm that i need to pee. The problem is, i am a squirter! and once it starts, it is hard to stop myself from going from a little squirt to just pissing myself, so it gives VERY wet squirting orgasms + it makes a real mess of my bedding! You can see how big the orgasms are though and that i like it LOTS!
