I pissed myself while fapping once. I started to feel like i had to piss a couple minutes of minutes after I started, but didn't want to get up to go to the bathroom, so I just kept edging. I ended up edging for like an hour. I was getting close to finishing when I started piss in myself, all over my desk, chair, and floor, and I couldn't stop. Luckily I had an empty water jug next to my desk (I used to keep change in it) and was able to catch about half of it. I then went back to fapping after I cleaned everything up.
