Original Description:
 
Lillian continues to let out clouds from her rump, as they carried a scent of freshly-baked, blueberry muffins, still traveling towards me. I respond with, “Mmmmmhh, I love your butt!” The clouds begin to deposite matter into my stomach, composing materiels which will later form up into a diaper, as it makes my stomach remain equivalent to and adult’s and the biochemistry will expand the food put in my stomach if I’m not fed enough. “fff.. fff. oooaahhh, what is that? Mmmmhh, your diaper is so soft! This smells and feels amazing!” I say bashfully, as I begin to feel butterflies in my stomach and a rise of excitment around my nether regions. “That’s right sweetie, breath it all in. I am glad you love my tush. Let it all happen, no need to worry for it. Just keep enjoying my wonderful tushy!”, said Lillian, calmly, as the cells manipulate my hormones, making me forever aroused, leaving me at the rate of fifty percent before climax. The percentage will change later when the diaper comes out. Which also leaves me to only cum in small portions and feel greatful of it during urination, in a new manner of it being extended. It also makes other changes as well, my legs will always be relaxed and temporarily relieved of any occuring tension or strength during upcoming accidents, my heart rate will slow from the ever-lasting-arousal, and will ease me from over-excitement during urination.
 
I begin to feel much younger and smaller, as I reach my early teen ages. My hoodie snugs up agenst me as I continue hugging into Lillians rump. Strangly enough, I feel hydrated and very refreshed. The cells begin to work on my body, giving it a better regenerative healing system, making it so everytime that I feel sick, ill, have a disease, or virus, the bodies immune system will have a better chance of fighting it, transcening it into diaper accidents, ontop of regenerating bruses or wounds faster. And Speaking of releases, the muscels around my bladder and bowels begin to feel more relaxed and more loose as I begin to feel tingly sensations around those areas, letting me know that I’ve became incontinent. I know that will give me a much true and funner experience of my diaper. As I get even younger, I rest back on my forehooves as I enjoy Lillians rump, now being pushed into me the more younger I get, rubbing into me, as my clothes get bigger on me. “Mmmhh.. please don’t stop!” I say in a silly, jittery voice, as the tingly sensations continue. The biochemistry does it’s work on my nether regions, making it so my accidents will be multiplied by three. So everytime I experience stress or negative emotions, that energy gets transcended into molecules that build up through my digestive system. I get to relieve myself from it, by releasing them out as accidents or farts. Either that or it happens in general.
