My idea is to tie yourself supine on the bed in a way that you need a lot of movements and at least 30 seconds to free yourself. So, when your bladder is going to burst, your only option is to drink some of your pee with a funnel-like object, raising your ass above your head, if you don't want to make a mess and pee on your clean bed.

The simplest way I found is to tie 2 scarfs together (or something like that) and make simple loop knots at the two ends so if I put an hand in one of the holes and pull, the knot will tighten around my wrist. I make the scarfs pass under the bed, I lay supine and tie my wrists so the only way to free myself is to crawl to the end of the bed, rotate, lift the bed to make the scarfs pass under the bed legs, and finally reach the wrist of an hand with the other hand. Movements that put a lot of pressure on your bladder. Naked, I tie myself this way only when I can't hold my pee anymore, with a bottle in my mouth with the bottom cut (the funnel-like object). I suggest to add a shoelace to hold the bottle in position without having to clench your teeth. Put some pillows under your back.

Fast, easy, and it will probably force you to drink some of your pee!
