Sometimes I fill my bladder with lube and then use it to apply lube to toys going into other holes... this time, I put the bottle itself in my cunt and then used it to lube up a catheter! With my labia spread painfully open with nipple clamps, I shoved the bottle of cum lube into my pussy, then took the cap off. It was much more difficult than usual to get a catheter fully inserted in my urethra, because the bottle was in the way, but I did it, and then trickled piss all over my vulva. As you'll see, a lot of it actually wound up inside the lube bottle! After that, I was eager to put larger toys in my urethra, so I pulled out the bottle and poured both pee and lube all over myself. I fucked my peehole with a glass dildo and then a silicone one, and when I wasn't way too close to orgasm to string words together, I talked about some of the things I really like about the feeling and tried to show you how my bladder sphincter resists being penetrated. After I cum hard, I pee to clear out my urethra, then take the clamps off of my labia and whine a bit about the pain.
