Master said I was being disobedient and needed to earn the toilet by holding my piss for as long as possible. I tried so hard not to piss my panties but my little bladder just couldn't bear it any longer.

Sometimes a slut needs a good breeding session ~~

Training my urethra with an extra thick rubber hollow plug before rewarding myself with a few orgasms ~~

Extended session gently stretching my urethra and stimulating my g-spot with a steel hollow sound before inserting my air pump balloon catheter to push on my bladder walls. Had to stop myself from screaming when I came because my roommate was napping in the next room ~~~

Short sounding session with a full bladder. Master was generous and said I could empty myself through the hollow rod.
