Today i had my first experience with holding pee and receiving tasks for it from reddit. I chatted with a few people and first drank around 600ml at home. I started listening to rain sounds on my headphones and started getting ready to go outside. I wore a bra, shirt, panties and a short skirt but also a coat to cover everything. I went to a nearby river and took 2 liters of water with me. I chatted with the people a bit and only had half a bottle of water left, when i really had to pee. So with around 2 liter already drunk i found a dark place next to the river (it was evening) and peed. I absolutely drenched my panties, removed them and put them in my mouth for one minute. After that i dried my legs with tissues, put my panties back on and went home.
