I want to curse you to be sealed up until your bladder is holding exactly a gallon, at which point the seal breaks and you suddenly have to hold it all yourself. I want the seal to return every time you empty yourself, leaving you with no choice but to keep filling up over and over again. The curse makes it safe to be that full, but doesn't stop you from feeling exactly how full you are and exactly how badly you need to go.
that sounds hot i'm not going to lie, only being allowed pee until i'm absolutely bursting. i have a habit of going before i'm about to go out and do something, so i don't get stuck needing to go without a bathroom around. so the thought of having to squirm around, desperately trying to hold it when i'm out in public because i physically couldn't go beforehand??? yes >_<
