So I was staying at my parent’s place, where I have literally no privacy. I sleep in the attic without a wall closing off my space, just a curtain. So everyone can hear everything and can just walk in without knocking. I woke up incredibly horny though and needed to shit really bad too. I already put on my diaper preventatively. The sensations of my poop filled colon just made me more uncontrollably horny. Even though I had no privacy I REALLY wanted to masturbate and poop in my diaper. I cannot control myself at all and start pleasuring my pussy. I writhe and squirm with pleasure, trying not to make any sound. That’s challenging when it just feels sooo good! With my other hand I massage my butthole through my diaper. I suppress my orgasmic moans cause I would just feel WAY too embarrassed if my family caught me like this. My arousal builds and approaches a full orgasm as I feel the big dense poo so pleasurably stimulating my colon and pushing against my butthole. I can’t hold it in anymore and my diaper visibly fills up with a huge load of thick warm shit. This arouses me so much that I cum hard in my overfull dirty diaper, restraining myself from moaning too loud. It was so pleasurable I lost myself in it, hopefully nobody heard it… Then I take off my diaper for you, first showing you my sexy big ass, hot feminine labia and very poopy butthole. I let out a very smelly fart as well. Then I show you what’s inside of the diaper, WOW that is a lot! And what an amazing mixed consistency, totally clumpy and constipated on one side, totally soft on the other side. It’s wonderful. Then I take a few big whiffs and you hear me react to the smell with as little sound as possible. I treat you to an extreme close up of the shit-filled diaper. I say goodbye with a close up of my pretty cute face and I make a gesture to let this be our little dirty secret.
