Obsession and Regression

Part 2
1

Dash slowly came out of her medically induced slumber. Unsettling to the Pegasus, her awareness faded in well before her senses... she couldn't move. Her surroundings were black and empty, and she had a deep pain in her gut. She couldn't open her eyes quite yet, but gradually she became more and more aware of where she was as her senses returned:

The first sense to come back was her keen sense of smell. Where she was now smelled warm, relaxing, and inviting... familiar, but she couldn't place it. Her hearing came back next. She heard hoofsteps above her head... above her head? Her sense of touch and orientation were coming back now, too. She was upright, which was odd seeing how she was just asleep... last but not least, she opened her eyes.

At first she saw just a blur. She was in a pink room, with a few lights in the corner. Was she in Pinkie's room? No, not there... she saw a small rectangular window high up, maybe 2 feet above her current position and 9 feet in front of her. Was she in a basement? Worse yet, there was light coming from the window... daylight. How long had she been?

She looked at the floor next. It was covered in a light cyan carpeting, matching her fur. There were a few boxes beside her, with a large navy blue satchel on top, and table which... looked like it belonged in a nursery.

She took in another wiff of the air...

Foal powder?

She tried to move her arms now that she was more awake and realized she couldn't move more than an inch or two. She looked over at her arms to see they'd been bound tightly to metal shackles which were attached to this odd table she was on, suspending her upwards. She felt weightless. She looked down at her legs to see a similar setup, then she noticed her attire.

She was wearing what looked like a sleeveless shirt, dark olivine in color. She noticed a small picture of Daring Doo over the heart, which made her smirk briefly, forgetting the confusing severity of her situation. She then noticed the shirt kind of connected between her legs in an odd way...

"A one piece swimsuit?" She asked herself out loud, squirming to get a better look.

She noticed the presence of buttons where the garment fastened between her legs. She felt this strange, somewhat awkward thickness between her legs. She squirmed to get a better look still, then heard a sound coming from around her hip area: crinkle!

This better not be what I think it is... She thought.

Sure enough, cranking her body from side to side while trying to get a better look, a bit of the thin white plastic she had on under the cotton garment showed through one of the leg holes. Rainbow Dash saw it and it confirmed her thoughts: Rainbow Dash had woken up dressed like a baby, bound and in a onesie, disposable diapers and all.

"What the hay!?!" Rainbow squirmed in the restraints. "Hey! Somepony get in here!"

She tried to open her wings, but then realize they were bound close to her body under the onesie. Everything was starting to sink in... whoever had put her there didn't want her to leave. She went from moderately creeped out and trying to get a picture of things to being full-blown scared at this point.

Luckily she heard somepony quickly descending stairs behind her.

* * *

"Honey, you're awake!" A familiar lyrical voice said from behind Rainbow. "You were napping so long I started to worry!"

The pony behind Rainbow Dash rotated the table she was on so that she now faced a door. She was nearly snout-to-snout with the golden pony.

"Hi, how are you?" Buttercup said in a joyous tone, nuzzling Rainbow. "I'm sorry you had to be asleep for so long!"

"Buttercup... what's happening? Why am I dressed like this?"

"Oh, Honey, I know you're upset... Are you hungry? I have plenty of milk for you stored in my body. I have to take special hormones Mr. Ironhoof gives me to keep it going nice and fresh. Try some!"

Rainbow Dash just stared at her:

"Come again...?"

Buttercup's demeanor had completely changed. She'd gone from sophisticated and understanding to... oddly silly and condescending. This had to be a game. Maybe it was a fetish of hers?

A few clicks to the table had Rainbow laying supine, looking up at Buttercup. Buttercup then lowered the table a few feet with a jack beneath it, winking at Rainbow Dash the whole time.

"I'd imagine you are very hungry after napping so long. Here..." she turned around, putting her back hoof up on the table by Rainbow's head, her teats now directly facing the bound Pegasus. "Drink up!"

Woah.

Rainbow Dash was face-to-face with Buttercup's engorged bosom. They were, indeed, quite swollen, and quite attractive in this state... Rainbow still throughly confused, just stared up at the teat trying to make sense of the situation.

"Drink, Honey... it's all for you!" There was a long pause in which neither pony moved. "Oh, don't make me have to get a bottle."

"Well, now that you mention it, I am pretty thirsty..." Rainbow thought aloud.

She opened her mouth in the direction of the teat, looking up at Buttercup.

"It's okay!" She cheerfully nodded her head.

Having nothing else she could do... Rainbow Dash hesitantly took one of the breasts in her mouth and began to suckle on its teat. After the first two sucks she was rewarded with fresh, warm milk. She was surprised when she realized it actually didn't taste all that bad... creamy and rich. She was still worried about what was going on, but seeing Buttercup this relaxed... it just had to be a game... there was no other explanation that made any sense to Rainbow.

"There's a good girl... drink up!" Buttercup took a hoof and gently stroked Rainbow's head. "You want to be big and strong when you grow up!"

Rainbow actually continued drinking for a few minutes. The milk tasted good, and looking up at Buttercup's smiling face felt... relaxing.

Rainbow Dash finally decided to break away.

"Okay! I'm done, I'm done!" she exclaimed, as Buttercup slid off the table and turned around.

"Good girl! You drank a lot for a filly your size... hope you don't get a tummy ache."

"I think I'll be alright," said Rainbow as Buttercup put the table back up and hugged her.

The rainbow-maned Pegasus felt gentle pressure on her back, followed by gentle pats... she was being burped.

It doesn't quite work that way with adult ponies, any pony knew that, but Rainbow still humored the older pony by forcing a burp... a burp in which she accidentally spit up a bit of the milk. Maybe it was in part due to the drugs wearing off in her system or her body just not being used to pony milk, either way she was embarassed:

"Sorry Buttercup!"

Buttercup pulled away, looking down her spit-up covered back. She then went through the wooden table next to the metal table Rainbow was on and got a cloth, gingerly wiping her back clean. She then turned to Rainbow Dash and gently cleaned her face.

"There's my pretty girl!" She exclaimed, beeping the nose of the bound Pegasus.

"Buttercup, I... uh... don't know what to make of this."

"Call me Mommy, sweetie." She replied, ruffling Rainbow's mane. "Buttercup's what grown-ups call me... you call me Mommy."

"Okay, Mommy... I don't know what to make of this."

"You're my little foal, silly. I'm here to take care of you!"

* * *

Buttercup turned away from the cyan Pegasus and went into the table... which resembled an old changing table. "I've got just the thing here... if I can find it..." She turned back to Rainbow with a book in her hooves and a big grin on her face. "It's story time!"

Dash's eyes were wide when she saw the title of the book: Daring Do and the Quest for the Sapphire Stone.

"That's the first book in my favorite series..." Excitedly commented Rainbow Dash. "I normally don't read, but I love that series! How did you know?"

"Some might call this book a little too grown-up for babies," replied Buttercup in a cheerful voice as she leaned against the table Rainbow was on. "But I believe in challenging my foal and exposing her to all sorts of neat things..." She cleared her throat. "Daring Do and the Quest for the Sapphire stone..."

Rainbow hung there and listened to the story Buttercup read to her. She enthusiastically set the atmosphere by reading very slowly and deliberately through the suspenseful passages, ruffling Rainbow's mane just about every time Daring got away, saying "you know she's going to be alright... she's tough and lucky.". When the story finally got to the villain Ahuizotl, her Spanish accent surprised and captivated the captive Pegasus.

The whole time Rainbow felt a need growing in her body need that all creatures great and small experience: a need to relieve her bladder. She kept quiet during the story, but after Daring Do got away the from the trap room, the book closed.

* * *

"That's all the story for today," said Buttercup, putting it away. She turned back to Rainbow and blew a raspberry on her stomach. "You are SOOO cute!"

Rainbow giggled:

"Hey! Cut that out!" Rainbow laughed as Buttercup met her eye-to-eye. "Mommy?"

"Yes Honey?"

"Can you get me a bucket..?" Rainbow added in a cute voice. "I gotta go pee-pee..."

Buttercup reached down and put her hoof on Rainbow's hip, crinkling her undergarments.

"You can't be serious." Rainbow replied, looking down at her attire. "That's totally undignified! Look, 'Mommy,' I really have to go pee... please get me a bucket... or something. Anything but that. It's going too far!"

Buttercup just looked into Rainbow Dash's eyes with the same level of compassion and love one would expect a mother would have for her own foal.

"You keep calling me, Sweetie, but you're not saying anything," she said, plucking a feather from her own back. "I know! ... you want to play."

"No, now I want to get down..." Rainbow said the second word very firmly. "Let me down. I've had enough of this game."

Buttercup brought the feather she'd just plucked up to Rainbow's lower set of exposed, defenseless hooves.

"No, no..." said the bound Pegasus. "Please don't! ... I really hate having my hooves touched."

"Is baby ticklish?"

Rainbow nodded sincerely.

"Don't..." She mouthed.

Buttercup lightly grazed her captive Pegasus's hoof with the feather, and as a result she fruitlessly attempted to pull it back. The restraints held her snug.

"No, please!" Cried Rainbow. "I can't take it..."

Buttercup gently worked the tip of the feather against the bottom of Rainbow's hoof. Her hoof moved only inches, side to side and up and down, while she threw her head about trying to retain her laughter... among other things. Buttercup ignored Rainbow's distress, tickling a bit fast as time went on.

"Please stop!" There were now tears streaming down Rainbow's face. "I gotta go... I gotta go..."

Instead of slowing down and being merciful, Buttercup's tickling got even faster and more intense.

Laughing uncontrollably, Rainbow Dash was fighting a losing battle. She was tickled non-stop and no matter how much she pleaded and struggled, she couldn't get Buttercup to ease up on her... if anything Buttercup seemed to tickle her HARDER the more she begged. Finally the inevitable happened: Rainbow gasped as she felt a warm, wet release between her legs. She couldn't help it, much less stop it once it started. All she could do in response was cry, much like a foal. Once her tears out weighed the laughter, Buttercup finally eased up on her.

The golden Pegasus finally put all four hooves on the ground as she asked:

"What's wrong, Honey?"

"Are you happy? I am soaking wet now because you wouldn't stop tickling me!" Grumbled Rainbow. "What in the hay is wrong with you!?"

"Oh."

Rainbow was still, feeling the warm, swollen wet material between her legs. Before she knew it, Buttercup walked behind the table and pulled on a lever, and... Rainbow was laying supine once again, looking up at the ceiling.

"You're not going to do what I think you're going to do..." she said quietly, as the table was slowly lowered.

Buttercup stood in front of her and began unsnapping her onsie.

"Come on..." weakly cried Rainbow Dash, as the dignity was being stripped away from her. "This isn't fun anymore..."

"There, there," replied the Golden Pegasus, rubbing Rainbow's stomach. "It's okay, Honey..."

Rainbow just looked up into her deceptively kind eyes and scowled.

Sure enough, once the onesie was open, Rainbow's squishy undergarment was carefully inspected, then removed by speedy yet gentle hooves which popped the adhesives wide open. Rather than watching, Rainbow just looked away... she knew there was no way to get out of this. Once the old diaper was removed, she saw out of the corner of her eye, the satchel being raised and set beside the table on a close box. She was then wiped off, a new diaper pulled from the satchel, which was slipped under her butt and taped into place. Rainbow Dash could now cross getting a diaper change passed the age of 3 off her bucket list...

* * *

"There! All better!" Buttercup pulled Rainbow's silent body back into an upright position, and began to put things away. "Mommy's got to go back upstairs soon to talk about grown-up stuff with guests who'll be here soon, but don't worry... she'll leave the light on so you don't get scared."

She looked over at Rainbow Dash, who was still scowling. She continued to look into Rainbow's eyes for so long that the bound Pegasus finally spoke:

"If you let me go, I promise not to press charges... I'll just go back to my friends in Ponyville and forget all about this... I won't even tell Rarity! Please... I just want to go back to my friends."

Again, Buttercup beeped her nose, giggling.

"Oh, sweetie, you make the most adorable baby talk!" She reached into the satchel. "Here. I have something for you."

She clipped one end of this thing to Rainbow's loose collar, then, before Rainbow could even see what it was, stuck the other rounded, rubbery end in her captive's mouth.

"You look so cute sucking on your little binky..."

Once she looked down and realize what it was, Rainbow immediately spit it out.

Buttercup sighed.

"Honey, I'm not to going to be here for at least three hours! That's a long time to a little filly like yourself to be alone... This is the only comfort you're going to have for a little while," She approached, gently rubbing the side of Dash's face. "I'm going to stick it in your mouth just one more time, and if you spit it out again it stays there... okay?"

Rainbow looked off to the side, not giving any sign of acknowledgement.

Buttercup picked up the dangling pacifier and forced it into Rainbow's closed mouth. It immediately fell, dangling once more.

"I'm very disappointed in you, sweetie..." Buttercup walked away, taking the used diaper and satchel with. "I think you need more time to nap..."

Buttercup then ascended the stairs behind Rainbow Dash, who was facing the window again. She was left alone, in the warm room, by herself... once again.

The lights were turned off right before the door closed. Rainbow heard at least two locks being bolted after the fact. She could still see, but the only source of light was from the window, which had a shade over it making it very dim.

"How am I going to get out of this...?" Rainbow asked herself out loud once she knew she was alone. "Where's Twilight when I need her?"

* * *

Rainbow spent at least an hour struggling in her restraints, hoping to find some weakness which would cause an arm or a leg to slip out. Maybe then she'd have the leverage to smash the other shackles one by one with her free hoof. She could kick the door open and bolt for her life in the confusion... if only she could find one weakness. She had no such luck, the restraints were well made and very strong. With no watch, no clocks, no way to keep track of time but the faint sunlight... Rainbow didn't even know how much time had passed for sure. Her situation was clearly laid out for her... she'd have to find some way out, but until then she was at Buttercup's mercy. What caused Rainbow's anxiety to stir the most wasn't the situation itself, but rather she couldn't decide if Buttercup was just plain cruel or totally nuts. Both were unsettling prospects, and without getting inside her head... she never would know. That was the last place she wanted to be either way.

After a while, Rainbow heard sounds above her head... ponies walking around in the upstairs. She called out:

"Help! Please help me! I'm being held against my will! You gotta help me... please!"

No pony came to her rescue. Perhaps no pony could hear her or no pony cared. The noises continued all the same, and eventually Rainbow Dash shouted herself so hoarse that she could shout no more.

* * *

Hours later, it was nearly pitch black and all was quiet. Rainbow Dash hung there, spacing out... thinking of better times. She hoped to fall asleep and wake up again, in her bed in Cloud's Dale... it never happened, though.

She heard bolts unfastening and a door opening upstairs. The lights came on, blinding her, as she heard a pony descent the stairs.

"Help..." She said quietly, with a tear in her eye.

"Honey, my grown-up friends are all gone now!" Said Buttercup's angelic voice from behind Rainbow. "We didn't hear a peep out of you... you've been a good girl!"

"I was shouting and you didn't hear a sound?" Asked Rainbow, as the table was turned so she was facing Buttercup, who was dolled up in fancy evening wear and carrying a small matching saddle bag.

"Let me see..." She poked Rainbow's crotch. "Your diapers are all clean, but you look so sad." Buttercup picked up the dangling Binky and stuck it once again in Rainbow's mouth. "That'll cheer you up!"

Again, Rainbow spit it out and struggled in her restraints.

"Come on! Just let me go...!"

Buttercup's response was, as always, to playfully beep Rainbow's nose. Rainbow had finally had enough of that and attempted to bite her hoof... she missed of course, but that made her feeling's known.

"Bad girl!" Buttercup replied in a stern voice. "Biting is NOT okay!"

Rainbow felt a sharp sting against her lower flank... Buttercup had disciplined her with a spank.

"Ow!" Rainbow cried. "That hurt!"

"You could have hurt Mommy a lot worse..." Replied Buttercup, shaking her hoof at Rainbow.

Again, Rainbow attempted to bite, and every attempt missed.... to be met by a sharp stinging sensation as Buttercup slapped her flank.

By the 6th whack, tears started to form in Rainbow's magenta eyes.

"We can do this all night, Honey," said Buttercup, with a mean smile. "... though Ironhoof tells me to be tough on you, tougher than I was on the others. He's raised many a foal. If you don't stop trying to bite me, I'll go back up stairs... I came down here to give you dinner."

"Food?" Rainbow said. Though her appetite was low, the food might make her feel better. "As in... real food?"

"Of course, sweetie!" Buttercup replied, setting her bags on the floor and opening them up. "Lemme see here..." She presented each item to the hanging pony as she named it: "I've got Strained Peas, Carrot Puree, Mixed Vegetables, Mashed Potatoes..."

The food came in jars.... small jars. It was babyfood.

"I'm not eating that!" Stubbornly snapped Rainbow. "Get me a carrot or a sandwich, I'll eat it... but not that mush! No way!"

"This is good food," said Buttercup sadly, looking up at Rainbow Dash. "Are you sure you don't want to eat it?"

"Yes!"

"Okay." Buttercup sighed. "I guess we'll have to see if you want it tomorrow..."

"Wait!" Rainbow sighed, thinking. ""Can't you get me a little bread or something then? Foals love whole grain bread!"

"You're too little," replied Buttercup, getting up and ruffling Rainbow's mane. "Most of that was babytalk, but I heard bread in there... maybe when you're older, Honey."

"Give me bread! Cut up a soy dog if you gotta! Anything!"

"Sorry, Honey... you can't always get what you want. Maybe in a year." Again, she playfully beeped Rainbow's nose as she finished putting things away.

Rainbow realized that Buttercup was indeed going back upstairs at this point. If she could just... get her talking, maybe she'd convince her to set her free. She wasn't smart or diplomatic like Twilight, but it was better than just letting her walk off.

"Wait...! Please don't leave me here!" Cried the rainbow-maned Pegasus. "Read me a story! Anything!"

"I'm sorry, Honey... it's late. You have to sleep down here in the Nursery." Buttercup walked up to her Pegasus captive and put the Binky back in her mouth, kissing her on the cheek. "Mommy loves you very much. You know that... there, there. It's okay! I'll see you again when it's light out." She hugged her tight. "Mommy won't let anything happen to you this time... I promise."

She then left Rainbow in the restraints, the pacifier still in her mouth.

Once the lights went out and the door locked... Rainbow broke. The pacifier fell as she sobbed herself to sleep... what had she gotten herself into?
