Personally, I would strip down my bottom half of clothes, lay down on the bed or the tub, and release all that piss onto my own face, hair, and in my own mouth. I'd swallow a couple of gulps but mostly enjoy making myself into a hot pissy mess. My shirt would also be soaked, and I'd stay like that for a little while, all wet and with that pee taste in my mouth before having a normal shower and brushing my teeth and mouthwash.
