I spread my pussy wide open with a Collins speculum, lubed up my peehole with a gloved finger, then slid in a smooth glass dildo. When it reaches my bladder sphincter, you'll see that I didn't warm that up with my finger- it resists, and I rock the dildo back and forth in small movements until finally it pops through the ring of muscle and into my bladder. Then I fuck my urethra thoroughly, rubbing my big clit as I do, until I cum. As I slip the dildo out, you'll see a gush of piss follow it. Then, I push a small glass butt plug into my peehole, the flat base putting my urethra on display as it squeezes the plug. I take out a vibrator and bring myself to another orgasm, and the quivers all around my peehole are even more visible now! Then I take the speculum out, spread my pussy with blue-gloved hands, and wink the plug in and out, showing it off for you.
