I just peed into a used container on the floor. It's really fun to pee in places that are not necessarily the toilet (especially diapers).
No, but I usualy pee in the sink when I stay for hours in the bathtub watching stuff on my laptop and I can't go out to of it to the toilet not to splash water on the bathroom carpet! I even bring a bottle of water and food with me in the bathtub when I plan a wet moviespree afternoon!
The movies/animes/documentaries are somethimes so interesting I don't even notice the water gets cold just when it's freezing already, I let hot water in again, too hot... then gets cold again, then again too hot.... after 3-4 hours of such adventure when the skin on my hands is just about to fall off, I get out and... I need to sleep, apparently I'm tired!
