My first time trying PVC panties! These clear plastic panties feel so smooth against my pussy. I slid a 30Fr catheter into my peehole, then put my endoscope in to show you the retention balloon inflating inside my bladder. It's a 30ml balloon, and it looks so big in there! Then I put the PVC underwear back on and change positions so that I can put on a leg bag. My bladder fills the leg bag so fast, and then I have a heavy bag of hot piss strapped to my leg! I use my hitachi as my extremely full bladder finally gets to release, and cum so hard I'm shaking. Then I take off the leg bag, sit down on the floor, and empty the leg bag into my PVC panties. It feels so warm and sexy!
