Tonya heard everything Leah was saying, but couldn't bring herself to believe it. That kid Tina had brought to the party couldn't have been Leah! Leah couldn't have just, in an attempt to get out of an awkward situation, found herself slowly becoming more and more like a baby. It had to be a prank. Right?
Just as Tonya decided that Leah was pulling her leg, just in a more extravagant way than usual, her friend let out a loud fart.
"Phew, that was nasty," Tonya said. Leah moved away from Tonya. There was a look of concentration on her face that Tonya recognized from babysitting countless toddlers and babies. Still, Tonya tried to deny what was happening in front of her. "What's with that face?"
"What face?" Leah asked. Her face reddened and scrunched up. A smell wafted from her. Tonya gaped at her.
"Are- are you shitting yourself?" Tonya demanded. Leah's eyes widened.
"Oh, no, not again!" she moaned.
"What do you mean?"
"This is the second time this happened today! During breakfast, Rita realized I was pooping, and I had no idea!" Leah sighed. "Guess I'll just..."
Leah stood and bent her knees into a squat. She began to grunt with effort as she actively filled her diaper.
Tonya could only watch in horror. This wasn't a prank. Leah wouldn't go this far. Everything she said had been true. The evidence was right in front of her, emptying what seemed like a massive load of poop into a diaper.
After what felt like hours, Leah finally sighed in relief and sat back down.
"Why did you just sit in your mess?" Tonya demanded. Leah looked at her, confused.
"What do you mean?"
"I mean- oh, never mind." Tonya sighed. "Go change yourself and we can continue our conversation."
"Um..." Leah shifted, no doubt spreading her mess all over her butt. "I- I can't."
"I won't tell Rita."
"No, I can't. I don't know how to change a diaper."
"Oh." Tonya paused. "All right. I guess- I guess I'll change you, then."
As Tonya lifted Leah onto the changing table, her confusion and worry over her friend coalesced into one decision.
