It was a beautiful, sunny day in the peaceful land of the Bunny Coalition. All the bunny citizens were merrily going about their day, where their fulfilling and productive jobs felt to them as more play than work. Harry the Foreman was directing his construction crew, Chef Hassenpfeffer was cooking up all sorts of delicious carrot-based dishes at his bustling bistro, and even though the Bunny Coalition had been at peacetime ever since the grand revolution that birthed the Coalition to begin with, acting military leader General Warren was standing a vigilant watch at the border tower. His intuition had always guided him to never let his guard down, for the good of his people he had fought so hard to liberate from the cruel subjugation of the monarchy of old.
There did remain one living facet of the old monarchy, however. Residing in the newly-dubbed People's Castle, there lived perhaps the most peculiar princess of the mystical lands. This princess in question was Princess Frankie, a celebrity figurehead who acted more as a diplomatic representative of the Bunny Coalition, so that the surrounding kingdoms, such as the Mushroom Kingdom or Sarasaland, would recognize and acknowledge the validity in their sovereignty. Despite such an important position in terms of the Coalition's stability, Princess Frankie lived most of his life as that of a spoiled (yet benevolent and innocent) child. Yes, his life, you read that correctly. Princess Frankie was a femboy, you see, previously a prince of the old monarchy, deemed too innocent to suffer the same fate as his neglectful, tyrannical parents, by the revolutionary vanguard bravely led by General Warren. Ever since the Coalition's ascension, Frankie had reclaimed his life under the title of Princess, and continued to live under the care of the old bunny who had practically raised him since her days as Royal Nanny, Mrs. Hopsworth.
However, Mrs. Hopsworth would soon find that her continued position as Frankie's designated caregiver would really have her work cut out for her going forward. As Princess Frankie now had more agency in his life, he felt the impulsive need to regress in his maturity, to make up for the lost childhood that had been stripped from him by his monarchic upbringing. He took to collecting and playing with a good many toys, crafted by only the finest toymakers in the Coalition, and his wide assortment of dresses and other fashion accessories were purely for his own amusement, as well as the adoration of the bunny citizens. As if any of that weren't childish enough, Frankie also took to casually sucking his thumb at the slightest whim of oral fixation, and even deliberately stopped using the toilet for relief, opting instead for relief right where he stood. Though that soon became cause for concern for Frankie, not because he was leaving messes all over the castle floors, but because he didn't want to soil anymore pairs of silky, satin panties, the highest quality undergarments in the entirety of the mystical lands. As such, as per Princess Frankie's request, Mrs. Hopsworth put him back in diapers, and resumed regularly changing him whenever needed, just as she did as far back as when he was two years old. His princess butt has not even touched a toilet ever since then.
These attributes did not render Princess Frankie a total baby, surprisingly enough. Not only was he half-bunny in his genetic makeup as indicated by his naturally occurring bunny ears and fluffy cotton tail, but at this point in time, he had very recently turned 21 years old. On top of both those precarious attributes, the isolation of celibacy he faced from having no compatible mates within the Coalition rendered him, well… particularly excitable. Despite his overwhelming urges, he at least had the decency to masturbate completely in private. He wasn't comfortable with any of the bunnies in his life being involved in such urges of his, especially not Mrs. Hopsworth, who he saw as more of an actual mother than anything else. All this considered, he still yearned for not just any partner, but a dominant one, of which he would happily refer to as "mommy" or "daddy" in a not-so-familial way, so to say. Little did he know, such a partner would come for him far sooner than expected…
