ureter releasing piss into bladder

Description: Do you love looking inside me as much as i do? i made my piss much darker than usual but used a catheter to fill my bladder with clear saline. then i used an endoscope to look inside and watched one of my ureters releasing pee into my bladder. it's not a steady stream, instead it looks a little like a tiny mouth that intermittently opens. the contrast between my dark urine and the clear saline made it easy to see what was happening. i emptied my bladder and refilled it, then watched my ureter a while longer. the inside of my body looks so alien! after a while of watching, i just had to reach for my vibrator. finally, after a satisfying orgasm, i removed the endoscope and the catheter from my bladder, spread my labia with my gloved fingers, and pissed out the mix of saline and tinted pee.
