Alright, you're ready to go. But where? If you have access to a bath, take your container of pee there (when you're done reading the page). Lie down in your pants, underwear and shirt in your bath.
If you don't have access to a bath, but at least a bed you can dirty, lie on that. Put on your pants, underwear and shirt, and pull the cover over your body. Keep the container of pee ready as well.
If you can't do that either, lie down on the ground. If you even can't do that, I guess you can go in the shower?
Well, whatever you choose:
When you start to pee yourself from despair, slowly poor the pee in the container over yourself until you're completely drenched. Enjoy this moment for a while, and when you're ready, you'll probably have to pee again. Get wetter and poor the rest of your stored pee over yourself too.
Hmmmmmmm, I envy you.
Now might also be a really good time to start masturbating, if you want to. At least enjoy your complete wetness for a while longer, even if you're not touching yourself.
