I insert the wrong end of an intermittent catheter into my peehole and talk about how you could slide the other end of the catheter into your cock and fill my bladder with your piss. I have a Collins speculum in my pussy, so you can see my big stretched urethra very clearly... and you can look into my cunt while it spasms, when I cum from talking about my filthy ideas about having my bladder full to bursting with someone else's pee.
