I've been sat at my computer concentrating so hard on making some 3D pissing clips (This isn't one of them, they'll be coming soon :P) that I hadn't realized how badly I needed to pee.
As I put on my 3D glasses and relax slightly to see how the clip looks, I start to feel it. I don't want to get up and use the bathroom now, I've spent hours getting this result! I wriggle, push hard between my legs and cross them tightly as I get the clip ready to play for the first time.
With my 3D glasses on, I lean back in my chair to watch the movie. Letting my body relax was a bad idea! As my bladder relaxed, a squirt of hot pee streamed in to my panties! Clamping my hand between my legs I manage to stop the flow! But mmmmm that warmth between my legs feels good! I've been working so hard, I think I deserve to relax!
With my legs open, I let out another squirt of pee. I watch as I do it, and see the denim sparkle as new pee flows over the old wet patch and makes a puddle on the chair underneath me. I can feel that my bladder is still very full! I stand up and feel the wetness between my legs, my bum is absolutely soaked in pee. I then completely let go! my panties flood and the peepee comes streaming down my legs. My jeans glisten and shine as the hot piss flows through them, soaking them totally from the top of my legs all the way down to my ankles, and even making a puddle on the carpet around my feet!
