So, I have this idea for an RP, but it's less meant as one continuing narrative, and more a collection of scenes with recurring characters. The basic idea is that I play a regular adult man, 28 years, and each scene starts pretty harmless, with me in a perfectly normal situation...but then, suddenly, something kinda shifts, I'm suddenly wearing a diaper and maybe more childish clothes, and the people around me start treating me as an "adult child" - physically still 28, but with the lack of privileges a toddler has. They talk to me like I'm a young child, give me diaper checks and changes, keep me away from "grown up stuff", use childish language, etc.

Some ideas for scenarios:

It's a class reunion, and I introduce my girlfriend to some old classmates. A girl I used to have a crush on suddenly starts talking about how she would always check and change me in school, and that she also babysat me a lot. My girlfriend tells her she's looking for a new sitter for me.

I'm at the public pool, taking a shower, when I suddenly feel someone touching me. It's my girlfriend's younger brother, and he's babysitting me while she's out. He makes me wear floaties, a swim diaper, and a girly one-piece swimsuit.

I'm sitting with my girlfriend in the living room, we have friends over, just talking normally, but then just as one of our friends wants to start talking about something sexual, my girlfriend clears her throat and subtly points at me, with the friend going "oh, right." Shortly after that, my girlfriend looks at the clock and is like "oh dear, past 7 already, someone's gotta get to bed" and then pulls back the waistband of the diaper I'm suddenly wearing and announces I'll need a change first. Nobody acts like this is unusual.

Me and my girlfriend go grocery shopping day, and at some point she's like "oh right! we're almost out of diapers!" and goes to a clerk asking where the diapers for adult children are, and the clerk's helpful and talks to her about me like I'm not there etc

It's my birthday, I'm celebrating with my girlfriend, mom, and sister. It's time for the presents, and as I open my mom's, I realize it's a frilly pink sissy dress.

My girlfriend is getting ready to go out with some friends while I'm on the couch playing video games when the doorbell rings and she says "oh that must be the babysitter!"

I'm just sitting on the toilet when the door opens and my girlfriend comes in and acts delighted and proud, praising me for using the potty and then wiping me after I get up from my plastic potty

I go to the doctor's office and once I'm called on and walk into the room, it's a colorful pediatrician's office, my girlfriend's suddenly there with me, and after greeting me, the doctor mainly talks to her
