I wanna say I barely made it home but in all honesty my body wouldn't have let me piss myself in public no matter how badly I needed to pee. That said, when I got home, it was getting pretty fucking hard to keep from doing an open pee dance, I felt my bladder pushing against my skirt and my walking speed had nearly halved.
I got inside and my roommate was taking a shower (He takes, no joke, two to three fucking showers a day I hate him a lot) and I had to actually fight to stop myself from crying out. I had to grab a McDonalds cup and a plastic water bottle out of the recycling because if I didn't I was gonna fucking explode.
The cup was around 750mL and the bottle was about 600mL, with the cup being completely filled to the brim and the bottle being filled about halfway. So about a liter. I feel like I've peed more than that before but I don't typically measure so I don't really know. I did leak quite a bit when I was switching containers as well but that couldn't have been more than 50.
I do know that that was probably the best piss of my entire life.
