Soon after she finished eating Angel went back up stairs quickly to her room. She then looked in the diaper she had on to see how full it was.

Natalie started to follow after her sister once she's done.

After looking Angel turned around only to feel her diaper get pulled out a little.

Natalie pulls on her diaper, giggling.

"Stop I know your up to something!" Angel said getting mad. She saw something in her sisters hand and squirmed. "No! Don't put that in my butt! That will really make me poop !"

"Too late!" Natalie shoves a pill up her butt.

"No! " angel trys to get it out but couldn't . "Crap! My stomach churning. " Angel said struggling to get the pill out. Soon she had to move her hands as something large began to push out against the pile under her butt.

Natalie began to laugh at her sister messing her diaper.

Angel felt the large log push out fully and whined as more logs moved into her birthday diaper. As her diaper sagged the poop started to push into the crotch.

Natalie kept on laughing. "Baby made a stinky!"
