It started like any other day: I got up and went to school like any other day. I don't like using the toliets at school so I'm very used to holding my pee all day until I get back home in the afternoon. On a normal day I would come home with a nice bulge forming on my belly, immediately run to the toilet and release more than a liter of pee. Not this day though. Since exams are coming up, my class decided that we should hang out in the park for a final afternoon before we'd all be stuck at home studying. I already felt a little sting in my belly when we left but that was alright. I was too excited to worry about peeing. I joined in and we went out. It was a nice and sunny afternoon. Some of us brought food to put on the grill and we had a lot of fun. Though the pressure inside my bladder started to distract me. "At this moment I would usually be on the toilet and release all of this." The party went on and I started feeling uneasy. We were in a public park and there were no toilets around. Even if I went home now it would be half an hour before I could finally pee! So I kept it all in and tried to keep a straight face while enduring the rising pain. I admit I kinda liked being exposed with no choice. Finally the sun went down and the group disbanded. I could barely stand up at this point. It had been a hot day so even though my bladder felt like exploding, I had continued to enjoy several cups during the party. On my way home I was so full my bladder was constantly twitching. The contractions made my dick hard which helped a bit with holding it all in. Arriving at home I suddenly had an Idea. I quickly put up my webcam and grabbed a measuring cup from the kitchen. I had started leaking and I had a warm feeling running down my legs while I set everything up. And that's how this video came together! Enjoy! ~
