Shameful Diaper Hiss. Broken Zipper

I am sitting in the park wearing a diaper under shorts, and suddenly realize that I have an unbearable desire to pee. On the way home, my bladder almost exploded so I stopped on the stairs to pee. There is a big wet spot on my clothes now! Fuck, this is so embarrassing! I started to carefully sneak into the apartment, so no neighbor would see me. When arriving home I felt another rush and ran to the toilet but the zipper on my shorts got stuck and for the second time I had another powerful hissing jet into my diaper. What a crappy day!
