My deepest, *darkest* fantasy?
Being tied up in a cold room, in white leggings and a white tshirt, nothing else, shivering from the cold, but being made to drink water consistently.
Knowing I’m being filmed, but not being allowed to pee unless I beg good enough, and unless I drink enough water.
Not knowing how much water that is, I have to just keep chugging. Eventually it all filters to my bladder and I can’t sit or stand still, and the shivering from the cold is making it all so much worse.
I keep begging but there’s no signs of permission being granted, so I keep drinking. And after a few hours of this, I stand with my legs crossed, hunched over, hands holding myself.
Next thing I know, I can’t hold it anymore and I start pissing… and just as I get past the point of no return, I hear someone tell me I’m allowed to go to the bathroom to pee.
And all I can do is cry from the embarrassment of knowing this is on film, and continue peeing myself until I’m empty.
Fuck, that's really hot. There's a story similar to that on AO3.
To add to yours tho, the idea of staying there and then changing you into outfits they want to see you wet in.
