A Night In Shining Armor's Mind

Cadance was relentlessly peppered with kisses on her head. Shining Armor gazed at a pink plot that was wrapped in a fluffy crinkly diaper, white on most of its core with purple swirling designs around the leg gathers and a pink heart right below her tail, which was lifted skyward by magic. The pink mare happily suckled on her purple pacifier; Shining had a happy little filly on his hooves, except he then realized that his front hooves were bound behind his back. The peppered kisses most certainly weren’t coming from his lips, which were pressed against a baby pink pacifier that when he tried to spit it out, stayed still in his mouth with only added pressure from the back of his head. He gave a muffled grunt and a reactionary squirm helplessly on the floor, hearing loud crinkles coming from his own plot, and realizing he felt free of a breeze below his tail and his groin warmly wrapped by what was obviously a garment identical to the one around his wife’s behind.

Shining knew about Cadance’s desires and loved to play along as her daddy, but never wore diapers or played the foal himself. He didn’t remember being unconscious before, all he remembered was watching his wife receive her precious filly time and discovering he was on the floor and couldn’t get up. He suddenly felt soft fleece wrap around his hind hooves and looked down to find pink frilly foal booties wrapped around the tips of them and himself donned in a pink dress clenched underneath the ropes with not nearly enough length to obscure the pink diaper that matched. Frills loudly adorned the back of this pink diaper and complemented the white tips of the dress. More squirming ensued as he tried to use his magic to free himself, but his magic sparkle didn’t appear over his bonds.

“I know you can do it, dear~ Like the good little filly you are~” Shining heard a voice say to his wife. He then heard a little grunt come from Cadance, her tail twitched while still raised by sky blue magic. Shining gave the pacifier strapped around his head a suckle, somewhat eagerly awaiting what Cadance was about to do, and although he helplessly lay on the floor, he had a front row seat. A crinkle accompanied a slight bulge starting to form under her tail, slowly expanding and causing a faint tint in the rear of her diaper. Shining imagined her pacifier suckling growing stronger as she did her business, which he was used to seeing himself. The suckling on his own certainly did. He squirmed some more, feeling deprived from being unable to properly reward her. He groaned in misery when a loud “bwrmph” escaped, and her diaper drooped much more drastically upon so, followed by a heavy exhale through her nostrils.

“Aw, does that mean you’re all done?” The pink alicorn gave a smile and a nod in response to the mysterious voice. “I figured you would’ve given Princess Shiny a longer performance, but short and sweet has its own charm, I suppose~” A white hoof firmly ran across her head, and a pair of lips pressed on her cheek after and released with a smack. “There’ll be other shows, but you should already know that since she’s such a good little filly~”

“But… She’s my good little filly.” Shining thought, growing more squeamish, unable to even stand. He craved being the one to give her his love; it was like playing a fantasy in third-person in his head, except it was actually happening, and he was so close, yet held back by his bonds and unable to do anything but wiggle on the floor. He could feel himself blushing. His eyes widened as he watched a white hoof slither down to the seat of Cadance’s freshly soiled diaper. Loud crinkling and a light long smush was heard when the hoof applied pressure, forcing a pacifier-muffled whinny out of the alicorn. “Is that what mooshing looks like from this view? It looks so much better than it feels. Her enjoyment is somehow very appealing from this angle.” Shining Armor was used to seeing her smile at him and kick her hind legs from beneath his chin while his hoof firmly pressed against her soiled diapers.

“I can tell you secretly like this, Princess Shiny.” Shining groaned while blushing; the ageplay and the mooshing, yes, but not being tortured by being forced to watch somepony else do it... Or was he enjoying that too? Or did he want to be the one with the hoof pressed into his diapered plot? Why did it feel like this mysterious pony knew the answer better than he did? The mysterious stallion’s red mane, white coat, and his sky blue cutie mark came into view; the sky blue brain with a splintering lightning bolt striking through it sent a dark jolt through his heart.

“Not him, anypony but him!” Shining now knew why this pony knew how he felt, and he felt betrayed by his feelings being an open book to this stallion but not to himself, and Shining could tell through the red-maned stallion’s wiley smile that he knew… And he knew all of it.

“And you should be proud of your little filly,” his hoof ran across Cadance’s flank and his entire front leg embraced her diaper closely, wrapping it in a hug, causing the alicorn’s wings to unfold in reaction, “she put her diaper to super duper good use~ But, you should already know she’s really good at that~”

Shining Armor’s pupils shrank, his puffing blushing cheeks growing brighter pink, the red-maned unicorn’s magic still lifting her tail and his smirk telegraphing to the bound stallion that his jealousy was being fed upon, practically devoured if that were possible. He wanted to be him. He wanted to be her. He wanted to be where he already was. The red maned stallion’s front hoof elicited more pacified giggles as he applied pressure on the mess within, then he started drawing circles around the pink but slightly tinted heart below her tail. This wasn’t fair, she loved being mooshed. Clockwise, counterclockwise, then he started peppering the garment in the same circular pattern.

Shining Armor then felt a pressure quickly grow in his lower stomach. He quickly gazed down at himself, noticing something he could’ve sworn wasn’t there before; his tail was lifted up by a collar fashioned to clamp around his tail like a barrett, a collar that was leashed to another around his neck. The very sight caused the pressure in him to grow extremely fast and he began to cramp. His first reaction was to try holding it in, but he knew his fate was sealed, and he broke at the very first urge to release it, and a loud “BWRMPH” received giggling from the other two ponies in front of him. His pink frilly diaper filled up rather fast, and the stallion felt it spread warmly in between the diaper’s inner walls and his plot. He still silently filled, even though the red-maned stallion kept chuckling. Shining felt the feeling of physical emptiness elate him, and the bulb resting on his tongue suddenly felt more enticing, and the pacifier gag bobbed up and down as he suckled. He continued to suckle, and just like his wife, he gave a sharp exhale through his nostrils when he heard one last splortch and felt himself stop. The cramps in his stomach faded into a great relief surging through his body which reflected through his completely red face… He was hoping he had more mush to push out… And he probably could’ve held it in if he really tried.

“I think it’s time we put Princess Shiny down for a nap and continue our playtime somewhere else, don’t you think, sweetie?” Shining didn’t want her to nod, but she did, and with a smile peeking out from behind the side of her pacifier. Shining gave a few muffled groans past the pacifier guard pressed to his lips. The red-eyed stallion raised an eyebrow. “You have something to say, little one?” Shining’s blush continued to glow brightly. “You only get three words.” Shining Armor watched a blue glow wrap around the pacifier gag, and he felt the pressure on the back of his head loosen. “Let me go” was going to be those three words, and it was going to be a barked order.

“MOOSH ME TOO!” Came out from the big begging blushing bound baby. The pacifier gag promptly went back in between his lips and the strap tightened around his head again.

“ERRR!” The red-maned stallion said, imitating a buzzer. “So close, but wrong. The correct answer was ‘moosh me please.’” Shining Armor groaned in response; a groan that was desperately begging for it, and a gaze that was begging for it too. Crystal clear blue eyes pleaded to cold blood red ones. “What do you think, Cadance? Was it close enough?” She only gave a giggle and continued to suckle on her pacifier in response. “I think that means ‘yes’.” Shining felt his heartbeat pound out of his chest when hooves lightly clipped against the ground, the stallion exiting his sight. Shining felt a hoof slightly press against his padded plot, barely squelching the mulch against him. “But I don’t think so.” Shining gave another begging groan then felt himself being thrusted upward off the floor. He then swiftly felt the warm mush press very firmly against his plot upon being lowered, but not by a hoof. He sat in a contraption that felt like a trampoline. Every bounce attempted to force a helpless smile behind Shining’s pacifier.

It wasn’t the same as a tender caring hoof, but every bounce gave him a moosh, every moosh gave him a jolt of joy, and every jolt of joy made resisting to smile harder. Every warm mooshy bounce against his plot made it harder for him to remember why he was upset. And he should be upset; he was about to be left bouncing in a messy diaper unable to free himself with his hooves bound and his horn inhibited. A spell forced his hind hooves to push against what little floor they could touch, except it wasn’t a spell, but a curse; a curse empowered by his own desire. The pacifier grew more tempting to nurse on, and he gave in to its calling. He shortly after gave in to another calling which was fulfilled in tandem with a white hoof stroking his blue mane; the front of his diaper grew warmer as his bladder relaxed. More squishes accompanied the crinkles elicited by the bouncing contraption.

“I think the filly’s pretty happy right now.” The mysterious stallion said as he walked away. “Come on, Cadance. Let’s leave the princess alone to let her moosh herself to her heart’s content. She’ll probably tire herself out and fall asleep before you do~” His wife only giggled in response, and that’s when frustration hit him like a chariot; it wasn’t fair, he wanted to play too. “Uh-oh, somepony’s jealous~” Damn him and his ESP. “Too bad, Princess, now moosh yourself and go to sleep. Maybe we’ll get that stinky princess butt changed tomorrow morning. Maybe a night in your mush will help you remember to always say ‘pwease’ and ‘fankyoo’.”

Shining Armor watched the stallion quickly escort the giggling princess out of the room, turning it dark as the door closed with only faint moonlight to illuminate his surroundings. He was beyond upset, left squirming to think dastardly thoughts about what kind of filly time fun his wife was going to have with this other stallion. Shining Armor began to jostle some more in the bouncer, feeling a fresh moosh, and another, and another. And the mooshing became the only thing on his mind, and the single greatest thing he loved to do.

Shining Armor saw light return to his darkened vision. He was back in his bed, lay beside his wife, who was rhythmically breathing and clad in a pink hoofed sleeper with purple soles on the hooves. He gave a reactionary groan from what he just dreamed about, Cadance afterward stretched like a cat and then rolled herself on top of him. He gave a reactionary “aww” and a smile, seeing her purple freshly awake eyes and lines curling upwards from behind both ends of her purple pacifier. He placed a hoof around the back of her head, leaned forward, and smooched her forehead before resting his head back into his pillow.

“Telling me ‘good morning’ with your eyes? I’m pretty sure that’s your way of telling me you need me to change a diaper that may be more than just wet.” Her pink cheeks were enveloped in a red blaze as her eyes darted into the corners. “You usually aren’t messy first thing in the morning.”

“Well, my jammies are locked and I had to go, and you were still asleep~”

“So you just woke up, filled your diaper, then went back to sleep? How long have you been stinky for?”

“An hour, maybe?”

“The key was under the lamp, sweetheart, you could’ve done it yourself if you really want-” He rolled his eyes and scoffed at himself, causing her blush to grow more intense and a giggle to slip out of her. His hoof brushed through her mane. “Oh, you didn’t want to, you silly filly~”

“Hehe, I like being a silly filly~ Although,” she crooked the pacifier to the corner of her mouth and spoke out of the free side, “you were writhing around in your sleep. Did you have a funny dream?”

“Writhing?” Shining Armor could practically feel his pupils shrink. “Really? I wasn’t talking in my sleep at all, was I?”

“No, nothing like that. What did you dream about?”

“Uhm, I’m not sure, actually. It felt really weird, but I can’t remember it now.” He wished he couldn’t remember it, or rather, wasn’t too sure if he wanted to, but this dream was one that was definitely going to stick around in his Mind- er, brain. He hoped he wasn’t blushing. “Yeah, it’s gone now.”

“Hehehe~ You’re silly.” Cadance then brought a front hoof to the zipper at the top of her sleeper, stuck in place by a small locking mechanism. She shied slightly away when he gave a smirk at her in response. Her blush grew brighter when his hoof snuck its way to her plot, patting lightly at the soiled diaper underneath her sleeper. His smirk was wiped off as his face turned beet-red in response. Tentatively, he pulled his hoof back and gave her plot a firm stamp. She whinnied, her face flushed, and she kept smiling.

Shining began to break a sweat. “What am I doing? Why am I doing this? She didn’t actually like mooshing, that was just a dream.” He quickly pulled his hooves back up to her back and started rubbing gently and his magenta magic aura draped over the lamp, lifting it up to reveal the key underneath.

“Darling, wait… I actually kind of like that.”
