You know, Orbees, those little water beads that swell up when you get them wet. The torture involves putting a whole bunch of them into my bladder while they dry so they expand inside, growing too big to pass out. This leaves me with a permanent need to relieve myself and a requirement of frequent trips to the bathroom as I can only let out a small amount of urine at a time. That's my fetish and if you don't like it you can leave.
