Rick and Morty: Morty's regressed time (Private with Academic Cartoons Fan)
 

Morty Smith was finally on summer vacation. This meant no school, more adventures with grandpa, and more time to be a baby! He ran into his room to get into something more comfy and babyish. The boy was in the middle of pulling out a onesie, thick diaper, and his paci when his grandpa rick walked in.

“What are you doing Morty?”

Morty screamed as he failed to hide his baby items. "Uh...um...n..nothing grandpa!" He stuttered. The boys face was as red as a cherry. "D..dont people knock a..anymore?!" He asked.

“What is with all these baby items? Did you get a girl pregnant?

"No! These are way too big for a baby, grandpa!" Morty said. He calmed down a bit and looked up at Rick. "T..these are mine..." He stuttered.

“So you want be a baby Morty?” He saw the onesie that Morty had on, and heard him peeing his diaper. “I guess that explains the pee smell when we go on adventures.

"W..when did you start noticing that i was diapered on our adventures?" Morty asked. He went to snap his onesie on but fussed because he found the buttons to be very difficult.

“The whole time. I didn’t want to embarrass you. I thought you had a medicial condition.” He takes the buttons off of Morty’s onesie and lays him down to change him. He swiftly changes him, washes his hands and rebuttons the onesie.

Morty felt himself regressing a bit while Rick changed him. He held a nearby stuffie close and looked up at Rick. "Faaankyoooouuu gampa!" He babbled

“No problem, Morty. Who buys this stuff for you?” Rick held Morty in his arms and rocked him.
