I am a submissive who cannot resist a challenge...... Especially where poop is involved.
One of my favourite experiences was when my Mistress took all my money, handed me a one day public transport rail card, and the drove me to the other side of town. She then waited with me until I managed to poo in my nappy, that I soooo enjoy wearing. Then she left me to make my way back via public transport to collect my car......
But, it was rush hour, the bus was full and you could smell my mess easily. I felt shame and humiliation to levels I had never experienced before. I could feel people looking at me. I sensed they knew. I was certain they were disgusted. I wanted to cry. I felt sick.
It was an experience that go me so aroused, that when I got my car back, I drove to a secluded spot..... Thrust my hand down my filthy nappy and masturbated into my poop.
It was mind blowing........ WOW!!!
