I was absolutely desperate, feeling naughty and decided to see how long I could hold my pee on a bare mattress. I challenged myself to try and hold hands free which turns out to be a lot harder than I thought. eep. Almost instantly pee starts leaking out of me in small drips. I shuffle, moan, and shake but can't seem to get a hold of my aching bladder that keeps leaking and spurting. Pretty soon I can't hold it at all and an eruption of pee jets out of me and absolutely destroys the mattress. Oops.
