I want to be tied up on a chair and left alone and forced to piss myself all day
You'd be watching on the cameras as at first, I try to hold it, but my arms and legs are tied so I can't close them
I'd be grinding into the chair, wearing jeans. The feeling of them tight against me would make it harder to hold. I'd start leaking, and it would be incredibly obvious while I kept trying to hold it. Eventually, I'd start wetting myself, piss pouring out of me as I slump down.
It would be hours before you'd come and collect me. You'd take off my jeans and underwear and clean me up, but not untie me. You'd put me in new underwear and a skirt, and untie just my arms, so you can see when I leak in my skirt.
You'd refill me with water and sit and watch as I lose control. Maybe you'd watch shit on your phone, playing river noises or people pissing themselves. It would be too hard for me to hold, and I'd start leaking, pushing my skirt between my legs. The wet patch would be so obvious, but it would also be my breaking point, wetting myself all over again.
At night, you'd tie me up on a plastic potty, saying I can go whenever I want, but I can't fill the potty till it overflows. You gag me with a dildo that has a little hole and hook me up to water so I can drink through the night to stay full.
You'd go to bed, but I would be up all night, squirming to not piss in the potty and wait until morning to use the big potty. I wouldn't be able to, and I'd piss in the plastic potty. Maybe I would be able to keep it from overflowing, maybe I'd overflow it because there would be so much in my bladder.
