Aaron thought for a moment, wondering what he could change with app. On a whim, he changed “changed” to “pooped”. Sure enough, it promptly took effect. He suddenly felt a pain in his gut and instinctively got into a squatting position, grunting a few times as a loud fart and a load of warm, stinking mush suddenly began to fill the seat of his new, freshly changed diaper, pushing it outward and leaving him standing in the bathroom once again in a heavily used diaper.
Aaron pressed his hand against the warm and heavy mess, squishing it against his rear. It was gross, but he guessed as long as he had the app he could change himself much more easily. Considering all the hard work he’d done in changing himself, he thought this seemed a bit counterproductive, but honestly didn’t seem to mind his newly messed diaper as much this time. It felt strangely pleasant to have emptied his bowels the second time.
Although he wasn't sure if he should leave the bathroom like this, after all he had been told to change it. Curious, he began to think about using the app to change his diaper this time. He looked at his phone app again and generated a new sentence, this time reading “The diapered teenager has just finished messing into the new diaper that he was supposed to change into.” and thought about what to change next.
