I have an unfinished story where I wrote about Nick and Finnick from Zootopia taking a drug that gives them mental age regression so they have fun and wear diapers. They keep their adult intelligence but are regressed emotionally to the level of kids, so they enjoy wearing diapers more than normal. If anyone wants to see it I will publish it, because I do not think I am going to finish it. Post a comment if you want to see it, but if nobody who already follows me cares I doubt anyone else will enjoy an unfinished story, so let me know.
