Mark felt something nudging him in the shoulder.
“Marky! Come on get up, it’s urgent!” came a hushed whisper.
He rubbed his eyes before opening them to Rebecca sitting there on her hands and knees in the crawling position.
“Becky…what’s going on? Why did you wake me up?” he asked tiredly.
“Listen I just woke up a few seconds ago and I gotta make poo poo real bad” she said and even in the semi darkened room he could make out a slight grimace on her face.
“So? You’re wearing a diaper so you can just go ahead and go” Mark replied yawning a little.
“I know I can but I wanted to wake you up so you can see me make a stinky since you didn’t get to see me do it the first time” Rebecca explained before suddenly letting out a groan.
“Uh oh” she said scrunching up her face.
“What is it?”
“I-I can’t hold it in any longer I’m gonna-”
Instead of finishing the sentence Mark watched as his sister abruptly turned around and started crawling over to the side of the crib with him enjoying the view of her diapered butt as she did so.
Standing up on shaky legs she grabbed onto the bars of the crib for support while she bent her knees, squatting a little while keeping her padded rear turned so it was illuminated by the glow of the nightlight. Rebecca then let out a deep sounding fart as she unloaded herself right in front of him, sighing in relief as she finally did her business.
“I-I’m making…p-poopie” she announced to her lone audience as she continued to push.
Rather than listening Mark however was more focused on the way her diaper pushed out in the back, transfixed by how it bulged outward because of her poo poo. He stared intently as the seat drooped inch by inch, sinking lower and lower between her legs now looking very saggy in appearance.
“Ahhh…that felt really good” she said as she finally finished filling her pants with the warm load, squeezing her legs together and holding the back of her full Pampers with one hand.
For the next few seconds the toddler quietly marveled at the size of the poo she had just dropped in her diaper. Rebecca could instantly tell that it was much bigger than the one she made at the park, the huge solid lump filling the whole seat and causing the tapes to stretch a little to hold the thing together and keep it pressed against her rear. Not only that but she also loved the way part of the mound of poop was wedged in between her butt cheeks and was poking her butt hole.
“I have to say making poopie feels even better the second time around” Rebecca said as she got down on her knees to avoid sitting down on her messy bottom.
“I know right? Making doodie is the best!” Mark agreed, “And just think you’ll get to keep experiencing that wonderful feeling again and again because you’ll never be out of diapers ever again since you’ll always be a toddler” he promised her.
“Really?”
“Yep and to make sure of it…” He touched the coin with his hand, “I wish Becky would never age past three years old just like me.”
Realizing she was going to be a baby girl forever she felt a surge of uncontrollable overwhelming joy.
Without hesitating Rebecca quickly crawled back over to Mark and wrapped her arms around him.
“Thank you so much Marky, you’re the best little brother ever!” she exclaimed as she hugged the other toddler as tightly as she could without hurting him.
“Aw you’re welcome Becky.”
As she pulled away from him they both became aware of a foul odor being to rise up from the back of her padding and fill the air.
It was small and barely noticeable at first but it was steadily growing in strength.
“I guess not even the Pampers can’t hold back the smell of my stinky forever” she chuckled as she covered her nose.
Mark gave a small giggle at that before also covering his nose.
“But now I really do need a fresh diaper” Rebecca said with a touch of seriousness.
She…
