I mean, I don't think they would like to wear them, more like they have to because they can't control themselves.


another option is maybe nightmare during the nightmare puts them in a "sleep walk" kind of state that she controls to force them to be in the babyish stuff and maybe a spell so they can't get rid of them themselves

Hmm… that is also not a bad idea but it isn’t really up my alley since I generally prefer that they are unwilling to wear diapers and someone else makes them wear them by force.

we could maybe say the first nightmare makes them either think they need diapers or start to have accidents, so they start to wear them because of that

Sorry for my absence. I have been stressed, busy and tired for days. Probably the Nightmare Moon one is not bad. Only thing is that I would prefer that they are diapered in real life rather than in a dream.

I do preffer those, could I ask which one of those ideas are "not bad", so we can maybe talk more about those

Hmm… not bad actually. Another question. Are you fine with anthro ponies?

ok, so some ideas:
mlp:
-nightmare moon returns, but only in dreams, forcing the mane 6 to have humilliating dreams to make them feel like helpless babies
-after a boys night where spike ends up telling discord how 'even flurry could beat this dungeon', discord annoyed makes a "baby themed" dungeon to try to humilliate spike
sonic:
-after a fight against surge, she actually ends up beating sonic, as she uses this chance to humilliate sonic and try to make it so people think that sonic is really just "surge's baby sister" to try to basically get him to feel how it is to be just a forced shadow of someone else
-murder of sonic the hedhehog au, where the mistery in the train is "baby themed" with sage basically using the chance to try to 'regress' sonic and his friends to try to re raise them to be part of eggman's army


sorry if they aren't the best ideas, just some I had from the top of my head

My top series are MLP and Sonic. I am personally into bathroom denial, desperation and bondage. The way I like RPs going is that a character forces another character to wear diapers and denies them bathroom usage and the other character tries to avoid using their diapers but cannot hold it in forever.

well, I mostly like to do stories based on an ip, mostly based any kind of regression, abdl and some level of humilliation, I can write a few if you want, i'd appreciate if you maybe pass me some cartoons or games you like to see if I have any ideas based on them

Hello there. That depends on what kind of RPs that you do. I am mainly into domination and submission.
