---This video has been discounted to celebrate the upgrades I've made to my filming equipment since I made it!--- I put an intermittent catheter into my bladder backwards, so that I could stick the end that's intended for insertion up through my cervix and into my uterus. Then I spent about twenty minutes waiting for my bladder to push plenty of pee into my uterus, alternating between having even more water and having intense orgasms.
