I've been diapered, and living as an adult baby, 24/7 for several months now. My Mommy and Daddy said I was only allowed to cum if I had a full, wet diaper and only then from humping on a pillow or stuffie. Well, it just so happens that my diaper is very wet and very messy, and I'd like to get it even stickier! So I pull out my favorite pillow and start rubbing. My diaper crinkles and squishes as I hump my pillow. I moan loudly as it hits the perfect spot on my clit. I hump it over and over again until I finally cum hard in my diaper. My diaper is REALLY full now. However I'm only allowed a change every 4 hours, no matter what. It's only been a hour since my last change, so looks like I'm going to have to wait in this stinky diaper for a while...
