Cadence's Discovery [Private MLP RP Between Nerdking1500 and Myself]
 

Twilight sighed a little as she slipped out the chest from her closet. Spike was with a dragon mentor and nopony was due to show up today, she'd even told her friends to leave her be today. Gently she unlocked the chest and slipped out a thick diaper and a pacifier. She had waited all day for this, and as such she had to pee so very badly. Slowly she slid the diaper underneath herself and taped it up slowly, setting her pacifier aside and started to wet. She looked down at her diaper and let out a tiny whimper. She loved this, but every time she made herself look like a foal about to cry, it just made it cuter!

Cadence had actually managed to talk Shining into looking after the crystal empire for a while, which left her with some free time. And there was nothing she'd rather do with her time off then see her favorite sister in law. She'd quickly gotten a train to Ponyville and made her way to the library. "Twilight, are you there?" she called, knocking on the door. "It's Cadence. I wanted to come by for a visit." she explained, opening the door since her and Twilight were close already.

Twilight laid there, whimpering cutely in the soaked diaper, it felt good to be able to be tha little foal again. Yet at the call of her sister in lay her cheeks flared and she quickly tried to cover up, only succeeding in throwing the contents around, her diapers now n the floor as she opened the door. Now Twilight was still there, blushing, and now truly looking like she was going to cry like naught but a foal.

Cadence stared in surprise at the sight in front of her. "Twilight?" she blinked, seeing the filly wearing a diaper. She looked around as well, also seeing the spare diapers, as well as a pacifier. "Twilight, what are you doing here?" she asked with a slightly confused look. She then walked over and, seeing she was going to cry, her instincts took over and she picked Twilight up with her magic before cuddling her sister in law. "Shhh, it's okay. There's no need to cry." she told her.

Twilight's eyes spilled over at that, small whimpers escaping her lips. Here was her foal sitter and sister in law seeing her most guarded secret. Still when the embrace came she couldn't help but snuggle into it a bit. "P-please don't tell anyone..." She whimpered out loudly, today was just supposed to be a day she could enjoy a nice diaper! She just wanted to get nice and padded and be that little foal, she just hoped Cadence wouldn't look in the chest and see her paddle...

"It's alright, Twilight. I won't tell." Cadence said, rubbing her back and comforting her, just like she did when she was a foal. "So, mind telling me what exactly you were doing?" she asked. She looked around a bit more, noticing some of the other things she had out. She picked up the pacifier and put it in her mouth to help calm her down. After another moment of looking around. She also noticed the open chest, and something else sticking out. Still holding Twilight, she walked over and looked inside, blinking at the paddle. "Twilight... it's alright if you like this sort of thing." she told her with a smile, hazarding a guess.

If Twilight's blush wasn't obvious before it certainly was then. Gently she suckled on the pacifier while her sister in law looked around at all the stuff she'd kept so well hidden. "I-I was relaxing, I-I do this when I'm alone to escape it all, to not have to worry about tests and studying and all of my duties as the element of magic; now that I'm a princess though today was the only day I got..." She trailed off, cheeks ablaze with a blush as dark as the sunset.

Cadence smiled and reassuringly stroked her mane. "It's okay, I understand." she smiled. "You know, I don't really have a lot of time off either in the Crystal Empire. Still, why do we just spend the day together. I can even be your foalsitter, just like old times." she added, giving her a smile and nuzzling her. "So, what do you want to do first?" she asked openly.

Twilight blushed rather deeply, Cadence was willing to try this? "Um I'm not really sure..." She admitted with quite the dark blush. "I-I uh usually u-use that after I'm wet." She said, indicating to the paddle with a blush so dark it could make blood look white. She was telling Cadence this?! Why was she, if this continued she'd think Twilight was a freak, she didn't even realize when her right eye and ears started twitching in worried panic.

Cadence blinked and looked over at the paddle, though frowned when she also noticed the twitches and instead started rubbing her head. "Don't worry Twilight. I'm not gonna tell anyone." she whispered before smiling at her. "Besides, I think it might be kinda fun." She carried Twilight over by the chest and picked up the paddle with her magic. "So, what's this for exactly? Are you not supposed to use your diapers, Twiley?" Cadence asked teasingly, almost like a mother playfully talking with a foal.
