Αντλώντας τον κώλο μου με μια γεμάτη ουροδόχο κύστη μέχρι να χύσω τον εαυτό μου

How much pressure can my bladder take? I can hold a lot of pee but today I went to a new level. I was already so full I could barely hold it. But then I put a balloon inside my ass and started pumping! My bladder got squeezed so hard I couldn't hold it any more!
