While on a zoom call for my class, I really had to pee. I was instructed I couldnt go to the bathroom until after the class was done. Knowing I had such a full bladder, and that I would have to be presenting soon, made it even worse to not fidget and move around. I did my best to get through the presentation without an accident. I quickly turned off my camera and muted myself, hoping to get some relief by pulling my panties to the side and peeing in my room. However, i forgot my teacher turned off the self mute function and EVERYONE saw me piss on my floor!
