A story in which I got permission from the legendary Bunnykisses to use her OC, Lily and mine, Alex.
======================================
Lily and her good friend, Alex went to an escape room- type place with 8 rooms in a hallway. When you completed a room with a puzzle, you went to the next room until all 8 were done.

The pink bunny and the white cat went into a dark, narrow room 1.
But a heavy door slammed behind them as a light shined on 2 massive diapers. The 2 looked at each other with confusion. Lily spotted a note on the floor.
"Welcome to the escape hallway. You have to complete 8 rooms to escape. You have no time limit. In this first room, there is a note under the diapers, it will instruct you to escape the first room."
The cat and bunny reluctantly picked up the diapers and read the instructions.
"Take tour clothes off and strap the diapers on and use it. The detector will determine if you used it. If you used it, you will progress to room 2."
The 2 knew if they decided, there would be some punishment. They had heard rumors of a player who declined, then he went missing, and he was turned into a baby. So, they put on the pumps, and they were handed bottles of water laced with a drug that let the water go down to the bladder with the blink of an eye, basically laxatives for piss.
Alex decided to try and take the diaper off, but the tapes were made with an adhesive that were mixed with superglue. Alex tugged, but it was no use.
So the two peed in the diapers, and Alex sobbed while doing so.
The sensor scanned the wet diapers, and opened the door. On to room 2.
"Congratulations player! You made it to room 2. Part 1 of this room will make you dress up like a baby. We will get your clothes from room 1 and show your options. You will choose what you wear."
Alex chose a purple onesie with the words "I've returned to diapers" because his other options were a pink onesie that said "Big Baby who loves their diapers" and a pink skirt was the other one.
Lily opted for a purple onesie with "I love diapers."
The next note read "part 2: you will learn how to become Adult Babies. You will squish and play in your diapers for a minute straight. You can grab on and wring out your pee to spread it to other parts of the diaper or just let the pee soak in your privates. You can drag your diaper on the ground to spread the pee. Hint: if you ever need to use the bathroom, you're in a diaper. Use it."
A timer began for 1 minutes and the 2 crawled around and squeezed their diapers.
After the minute, the players were soaked.
They proceeded to room 3.
Two highchairs were in the room.
"Room 3 let's you choose 3 ingredients to have in a mush. Alex chose Beef broth, Sugar snap peas, and corn. Lily chose Carrots, Celery, and Chicken Broth.
The 2 were spoonfed by robot arms. They gagged, but moved on to the halfway point.
Room 4 presented the bunny and cat with a half gallon bottles filled with milk. They had to chug it in under 5 minutes. However, when they were drinking, their bladders both leaked, and the diapers grew with pee.
Both noticed the larger pamps after the bottles were empty.
Room 5 was a tutorial of how to use rattles, pacifiers, and that ring game. The 2 actually enjoyed that room.
Room 6 was a room of cribs, mobiles, and changing tables. After the 2 got 10 minutes of sleep in a crib. But the 2 were so sound asleep that poop came out into their pads. The 2 were given diaper changes with ample amounts of baby powder and thick diapers.
On to room 7. It was basically a review of everything. They had to spend 30 minutes to:
•mess in their diapers
•Eat from a baby spoon and and drink from a baby bottle
•play with toys
•sleep in cribs
• And wring out their diapers.
The 2 did everything in under 20 minutes.
Room 8. The final one.
It was a room surrounded by 4 walls of LED Lights.
Then a screen of swirls came on.
They were being hypnotized.
"Well done. You have completed the hallway. But you will now wear diapers and baby clothes and act like an adult baby for the rest of your life. Squish and use your diapers, drink from bottles and eat mush, play with baby toys and sleep in cribs. We will supply you with a monthly supply of diapers, some pacifiers, some toys, and baby food. You will pick out your clothes. Have a great day!"
The 2 walked out as the screen turned off. Lily and Alex went shopping for clothes and other things after they exited the escape room. A series of escape rooms would change their lives.
The 2 parted ways for the day and lived their adult baby lives.

THE END

Sorry guys, I shortened the story because I could not come up with extra content.
Thanks again to Bunnykisses for letting me use her OC.
