Jess was surprised when the toddler that used to be her grown up mother picked her up instead of one of the others.
"Mom, you're gonna wear me?" she exclaimed in surprise at being chosen.
"That's right honey" her mother answered with a giggle, "I want you to be the first to experience what it's like to be used by a baby."
Unfolding and laying down the Pamper that was Jess, the regressed adult quickly sat her rear down on the open seat. Feeling the baby girl's butt land on her Jess felt herself flattened as she cushioned the posterior.
"Why are you doing this to us?" Jess asked her mother telepathically as she continued to put her on.
"Why its very simple sweetie. When I saw you and your friends had a diaper fetish I just knew I had to share mine with you all. Thing is that mine is a tad different from yours. You see while you like transforming into diapers and getting used, I rather be a baby and do the using of said diapers. So when I saw that device of yours could make it a reality I just had to make you girls my own personal Pampers" she explained as she pulled Jess up between her legs and taped the sides before sitting up, her skirt covering and almost completely hiding the disposable garment.

"Fine...Wait, WHAT!?"
"Yeah I was originally on my way to the bathroom when I decided to check on you girls. And turning myself back into a toddler didn't help things much" her mother said squirming in place while holding her stomach.
"But mom we only like wetting and being wet on" Jess replied.
"Yeah and I'm honestly not sure how I feel about being messed in Jess's mom" Cassie added.
"I don't wanna be pooped on!"Kate shouted.
"Don't be a bunch of babies girls." The regressed mother paused to giggle at the irony before continuing, "I can assure you all will lov- hrrgh uh oh sorry Jess but I gotta go poopy right now" she groaned out suddenly as she quickly rolled onto her back. Grunting the baby girl raised her legs as she pushed and let out a big solid turd right into her diaper. Jess felt herself rapidly expanding to accommodate the large smelly log which formed a bulge in the back part of her.
"Ahhh that feels much better" the toddler sighed in happiness at her doodie filled Pamper.
As her mother lay there sucking her thumb and clearly enjoying the dirty diaper that was her, Jess reflected on her soiled state and found she...
