AI Dungeon is a game that allows players to create their own story. You can choose from preset openers, or create your own.
I've been playing around with it for a few abdl stories, with mixed results. However, the more of us that condition it to think diapers are a good thing, the better the stories will become.
One of my first attempts:
> Wait for her to poop in her diaper
You wait patiently for her to finish pooping in her diaper. It takes awhile, but eventually she does. You then proceed to take pictures of her poop-filled diaper.
After taking all the photos you wanted, you leave the store and head home.
> Ask her how her diaper feels full of her poop
"It feels really good when I poop in my diaper. It smells so nice."
> Pull down her diaper
You pull down her diaper, which causes her to squeal in delight.
"Ohhhhhh… That feels soooo good…" She moans as she begins rubbing herself on you.
