Fluttershy and Marble would be the type of shy girls that secretly wore diapers in their downtime. It'd be adorable if Fluttershy was trotting about, and accidentally sees Marble on the farm or inside her room through a window wearing a diaper, and Flutters giggles to herself and blushes. She goes to the farm (Marble is watching over the place while her family is out), she puts on a diaper and heads up to Marble's room. She walks in while Marble isn't paying attention, and says "M-Mind if I join you Marble?"
As the saying goes: It's always the shy ones. Fluttershy and Marble would be the type of shy girls
I just got done reading this fic, and I couldn't thank you enough for this recommendation.
- Marble being SUPER adorable, and the hint at Marble and Fluttershy possibly being more than just friends is just eeeeeeeeee!!!!! <3. - Fluttershy wearing a big poofy diaper WHILE wearing a black kitty costume was just torturing me with CUTENESS (my Fiance was dying of cuteness overload too) - Coco wearing a maid outfit with a poofy diaper was quite a surprise, considering what her job is at Rarity's boutique. - Marble, who "just wanted to be pretty" (spoiler alert: She's ALWAYS pretty), wears a cute princess gown while in a poofy diaper was a surprise. A part of me expected/hoped she'd wear something like a cute bunny outfit like Fluttershy's kitty outfit.
To top it all off, it all ends with them humping and grinding their poofy diapers together, and holy shit: when Fluttershy hovers her big poofy diaper over Coco's face to literally use it as her "litterbox" as she floods her diaper with poopy, is just *chef's kiss*
I will say, it's a shame that Marble didn't do anything (other than cum) in her diaper. It would have been super adorable to have her accidentally pee, or have her poop her diaper while her face was burried in Coco's pee-soaked diaper as she came.
