With a Collins speculum in my pussy, I slid a Killian nasal speculum all the way up my urethra and into my bladder. You'll be able to tell the exact moment it enters my bladder, because the piss starts trickling out of the speculum. Once my peehole is stretched wide open, I use a pair of forceps to shove a cluster of nettle leaves deep inside it, then pull the speculum out so that my urethra closes around the nettles and gets stung badly. Not quite satisfied with how excruciating it is, I shove some nettles in my stretched open cunt as well. With a vibrator on my clit, I manage to orgasm, but you'll hear my whimpering and cursing intensify as I squeeze the nettles and am stung even more. Finally, I take the nettles and Collins speculum out, and spread my pussy so you can see how painful and swollen everything is. I finish up by pissing in order to rinse any remaining bits of nettles out of my urethra, but the pain lingered for the rest of the night.
