Unruly Piss in the Kitchen Sink!
You know I have the habit of marking new spots with my piss. Sometimes it's not that easy, because it's quite unruly. You don't just piss on other people's kitchen sinks. But I take advantage of the host's short absence and relieve myself right there where hands are usually washed. I know it's not supposed to be done, but it excites me every single time!
