New Sensations In Procreation

“Thanks for helping me bring some of these books back from the castle Fluttershy. It would have taken all day by myself.” Twilight sighed thankfully as she and Fluttershy set down the last of several boxes filled with tomes and volumes from the library of the Everfree Castle.

“No problem, Twilight. It was my pleasure. Besides, most of the critters are with their families this week so I didn't have much to do today anyway.”

Twilight smiled. “Well, thank you regardless. Now I can go through some of these books without constantly having to travel back to castle so often.”

“You're going to go read all these books?” Fluttershy asked, giving Twilight a concerned look.

“No, not yet at least. I plan to compare the books from the castle with the catalog from the Canterlot Royal Archives.” Twilight explained as she moved over to the the boxes and started sorting the books into neat piles in the main room. “That way I can see exactly what books have been lost since the castle was abandoned and possibly have some of them reprinted for other collections.”

“But this was only one shelf. Are you sure you don't need help sorting them out?”

Twilight looked at the massive pile as the sheer scale of what she was doing dawned on her. “Granted, I may have my work cut out for me.” she started, “It wouldn't be too much to ask for some help, would it?”

“Well, like I said, most of the animals won't be back until later this week, and some of the girls might be able to help as well. I can come by tomorrow and help if that’s alright.” Fluttershy offered.

“Sure. That would be great. Pinkie should be back from her family reunion tomorrow and Rarity has the day off the day after that. With everypony's help this should go by a lot faster.”

Just then the clock on the wall began to chime, its hands showing that it was well into the evening.

“Oh my.” Fluttershy started, “Is it that late already?”

Twilight chuckled a little before answering. “It seems we lost track of time. You can head on home if you want. It's getting late and after the day we had I think we could both use some rest.”

Fluttershy nodded as she followed Twilight to the door, but just as they reached it an impatient knocking sounded from the other side.

“That's strange. Who would come by the library this late?” Twilight quickly opened the door, only to find Rainbow Dash on her doorstep.

“Hey, Twi.” The pegasus greeted. “Mind if I come in?”

Twilight stepped aside as she waved her hoof, motioning for her to enter. “Sure thing, come on in.”

As Dash entered she noticed that Fluttershy was there as well and extended a hasty greeting to her.

“So, what brings you by so late? I thought you would be back at home relaxing from your trip. Speaking of which, how was your tour?”

“Well,” Dash started, “I actually just got back, and the tour was amazing. Thanks again for the tickets.”

“You just got back?” Twilight questioned. “I thought you said you were going to be back mid afternoon.”

Dash guiltily turned her eyes away from Twilight and Fluttershy as she rubbed her hoof. “Well… I got a bit side tracked. Which is actually why I'm here.” Dash reached back and took off her saddlebags, setting them down in front of her and pulling open one of the covers. “It's okay.” she murmured softly. “You can come out now.” Not a moment later two blue blobs slowly rolled out of the bag, moving around like puppies, cautious of their new surroundings.

Twilight and Fluttershy both looked on curiously as the blobs rolled about, investigating their surroundings.

“Rainbow Dash, what are those things?” Twilight asked as the blobs made their way about the room, poking around like they were tasting the air.

Dash giggled nervously. “Well, I was kinda hoping you could tell me. I just… um… found them near this stream when I was on my way back.”

Twilight turned back to Dash. “And you thought it was a good idea to pick up two completely unknown creatures and bring them here? Do you remember the parasprites? They could be dangerous!” She scolded in a stern voice, turning and pointing a hoof in the direction of the blobs, one of which had climbed up on a table covered in beakers and vials.

“Well it seemed.. .friendly enough when I found it. Ah- them! I meant them.” Dash quickly corrected herself. “So I'm guessing you have no idea what they are?”

Twilight sighed. “No, I don't. They don't remind me of any creature I've heard or read about in my books.”

“Well, what about the books we got from the castle?” Twilight and Dash looked over to Fluttershy who had a blob perched upon her head. “I think I saw a few books about animals when we were moving them here. Maybe there's something in there.”

“You might be right, Shy. I think I remember what box they were in, too.” Twilight trotted up to one of the several boxes and began sifting through it with her magic, distractedly mumbling the names of the various works before setting them aside and grabbing another.

“Hmm. This one looks promising.” She said, hefting a decent sized book from the pile. The other two ponies, with blob in tow, surrounded her as she set the book down on her desk.

“‘Rare and Curious Creatures of a Questionable Nature’,” Twilight began, “Interesting title. Now let’s see-”

The sound of broken glass and splashing liquid filled the room, causing the ponies to jump with a startled cry. They looked over and saw the first blob on the table near broken beaker and the remnants of its contents. The blob looked around before catching Twilight's gaze and noting that she was obviously not happy about the beaker. To save itself, and the remaining glassware, it dropped down off the table and rolled over to the girls before hiding itself behind Dash's legs.

Twilight let out a heavy sigh. “Anyway, where were we? Oh, right, the book.” She said as she gently opened the cover. The pages were dusty and yellowed from age, but the writing was still legible enough to read without much difficulty.

After several minutes of flipping through the book, Dash could no longer sit still.

“Is there anything in there about them?”

Twilight huffed, but kept on searching through the book. “There's a lot of creatures in here I've never heard of before. I’m fairly certain it’s in here, we just haven’t found it yet.”

Dash groaned in frustration, pulling her hooves down her face as she did so. “Oh! Here it is!” Twilight called, slamming her hoof down on the page next to a simple sketch of the blob and a page full of text.

“What does it say?” Fluttershy asked as she leaned in to try and read the words scribbled on the page.

“Well,” Twilight started, “It says that they are called slimes. ...could have guessed that on my own...” She mumbled under her breath.

“Does it say anything useful?” Dash asked irritatedly.

Twilight scanned the text, reading it aloud as she went.

“Slime gelatus

These small, gelatinous-like creatures, while rare, can be found near rocky structures, rivers and other bodies of water, as well as caves with bodies of water within them. Despite its primitive form, Slimes are actually quite intelligent, capable of expressing complex thoughts and ideas through simple pantomime and body language. Slimes are quite friendly, often expressing affection through physical contact such as pressing or rubbing against one's body. They are also very tactile creatures, often having to physically interact with an object before being able to understand its function.

A slime feeds by absorbing nutrient rich liquids, which it seems to have an innate ability to find and can live almost indefinitely so long as the main body does not dry out or the core is not harmed.

In order to reproduce a slime must find a willing, female host to occupy as it is not strong enough to restrain beings of a large enough size for its needs. The slimes begin by working… themselves… into...”

Twilight stopped speaking, but continued to read on intently before sitting back.

“Rainbow Dash? Did you find both of these creatures, or did you only actually find one?” Twilight show Dash an accusatory glance.

Dash grimaced, “Well… uh, you see-”

“Rainbow Dash!”

“I'm sorry! I've been in heat all week and I wasn't quite thinking straight when it showed up!”

“Um, wha-," Fluttershy started but was cut off.

“These slimes, as they're called, need a host to reproduce.” Twilight explained. “They do this by using a female's womb, and there's only one way they can get there.”

It took a moment for the butter yellow pegasus to realize the implications of this. The moment she did, however, caused her to blush furiously. “Oh, my. You let them do that to you?” she asked, looking over to Rainbow Dash.

“Yeah, I did...” Dash admitted in a dejected tone, “But in my defense, it felt amazing. A little weird, but amazing.”

Twilight just rolled her eyes. “That doesn't mean you should have sex with it.”

“Look, can we just move past this?” Dash pleaded, “I can't just leave them alone, I've tried, I also can’t take them to my house.”

“Why not?”

“They aren't like pegasi or gryphons. They'll just fall through the clouds. Could you maybe use that cloud walking spell on them or something?”

Twilight looked back at the book, reading more about the creature's before looking up with a unsatisfied snort. “Well I can't do my cloud walking spell as it seems that magic doesn't last very long, if at all, on them.”

“Well, what am I supposed to do then?” Dash asked.

“Maybe you should have thought about that before you mated with it.” Twilight replied, throwing her hooves in the air in frustration.

“I'll take care of them.”

Dash and Twilight looked at Fluttershy in surprise. “Fluttershy, are you sure? What if they try to… you know...” Twilight cautioned, the reason for Twilight's concern causing her friend to blush again.

“The book said that they need a willing host. So as long as I tell them to not do anything, I should be fine.” Fluttershy reasoned, petting the slime next to her. “Besides, they seem well behaved for the most part.”

Twilight's face scrunched up in thought for a moment before she let out a defeated sigh. “If the book is telling the truth, then I guess it's safe. Just bring them back tomorrow. I'd like to take some notes on them later.”

“Alright, then.” Dash concluded. “Fluttershy can look after them for a bit while we try to figure out what to do with’em.” Fluttershy smiled and nodded her confirmation.

Twilight nodded her head too. “Agreed. We can pick this back up in the morning. You two should head home before it gets too much darker.”

With that the three ponies made their way to the door, Fluttershy stopping briefly to let the slimes climb in a spare saddle bag Twilight had before placing it on her back.

Once outside, Dash said her goodbyes and rocketed off to the other side of town. Fluttershy was just about to start walking off before Twilight stopped her.

“Are you sure you’re going to be okay with those things?” She asked again, concern apparent in her voice.

Fluttershy nodded with a smile. “Like the book said, they only use willing hosts. So as long as I tell them ‘no’, everything should be fine. Besides, if anything does happen, I can just fly away.” she flared her wings slightly to prove her point. Her reasoning did little to alleviate her friend's concerns, though.

“I know, but still. These things just give me a bad feeling. Promise you'll be careful?” Twilight asked.

“Pinkie promise.” Fluttershy replied, performing the motions of the sacred vow before turning down the road toward her forest side cottage.

_________________________________

The last of Celestia's light had faded beyond the horizon when Fluttershy made it home. The room was silent as she opened the door, the usual commotion of the various animals she looked after now replaced by the creaking of the door and Fluttershy's own hoof steps. Pulling the saddlebags from her back she let the two slimes crawl out.

“You two make yourselves right at home. If you need anything just-” Her words were cut short by a powerful yawn. “Excuse me. It seems moving all those books with Twilight wore me out.” She figured as she glanced over to the clock on the wall. “I guess it doesn't help that it's already so late. If you two don't mind I think I'm going to go get ready for bed. I have a place you can sleep up here if you want.” She said, already heading up the stairs. The slimes followed suit, clumsily hopping up the steps one at a time.

Fluttershy opened the door to her room allowing the creatures to enter. One of them hopped up onto the bed and began jumping around playfully like an overactive filly, while the other followed her to the washroom as she quickly washed her face in the sink. The slime hopped up on the edge of the basin and sniffed at the water running from the tap. Fluttershy let the water run a few moments more as the slime latched itself to the faucet and chugged down the liquid, growing slightly before the mare turned the water off.

Slime in tow, Fluttershy walked back to the bedroom where the other slime was still bouncing around.

“Alright you two, playtime is over. You can sleep in here with me tonight, okay?” The now larger slime hopped up on the bed with the other. Fluttershy was hoping that they would sleep on the animal beds scattered around her room, but it seemed that the slimes were quite happy sharing the bed with her. With a resigned sigh, she allowed them to get comfy, rationalizing that there was plenty of room for the three of them anyway.

Fluttershy crawled under the sheets as she clicked off the bedside lamp. She bid goodnight to her visitors and closed her eyes to sleep, but the slimes continued to move about on the bed for a bit. Soon enough, however, the slimes settled down and stopped moving, allowing the mare to begin drifting to sleep.

“EEEP!” Fluttershy screamed and drew her legs in as something brushed against her in a very private place. She flicked on the lamp and looked under the covers to find the larger slime under the blanket, looking up at her. She drew back the covers as it squeaked softly, almost pleadingly, moving closer to her. Fluttershy quickly knew what it was trying to do and drew her hooves away again. “No. Bad slime!” She scolded, causing the slime to recoil and begin to move away like a frightened puppy.

“Oh, I'm sorry.” She apologized quickly, leaning forward and petting the slime in an attempt to cheer it up. “I didn't mean to sound so mean. I just promised Twilight I wouldn't let you do that.”

The slime looked up at her as it chirped again.

“Well... I promised her I would be careful.” She thought aloud, the slime still staring at her as she stroked her hoof across its membranous skin. Fluttershy felt a warmth creep up into her face as she considered letting the slime do what it wanted, if only to make it feel better.

“...and Rainbow Dash did say it felt good.” the warmth spread further out as it started to make its way down to her most private places. “She didn't seem any worse for wear when I saw her.” Fluttershy continued, the more open she became to the idea.

Her mind felt like it was starting to haze. Her body now moving seemingly of its own accord, Fluttershy stopped petting the slime and leaned back, propping back against the headboard. Never once breaking her gaze with the creature, she slowly spread her legs apart, revealing her marehood. To her surprise, she noticed she was starting to become wet. Her lips were slightly puffy and began glistening as droplets of her arousal collected.

Seeing her present herself, the slime began moving forward tentatively. When she gave no sign of resistance, the creature moved forward to her mound and began running a section of its gelatinous body against her slit.

Fluttershy's body fell limp at the slime’s touch as it continued to flick up and down her entrance. Every touch sending sending a small wave of pleasure through her body. Her heart began to beat faster the longer the slime teased her, her breaths becoming short pants as the pleasure began to build in her belly. “More...” She moaned with a ragged breath. The slime seemed to hear her plea, as it focused itself and pressed into her tunnel, spreading her lips apart as it made its way in. After a few inches it started pulling back, but pressed forward again with more force as it started pushing in and out.

Fluttershy was lost to the world. The pleasure building within her was the only thing that mattered to her and every thrust from the slime only helped to increase it. Every passing moment was utter bliss to the mare as the slime kept pressing further into her with each thrust. One thrust in particular found itself hitting right against her g-spot and sending out a momentary spike in her pleasure. The slime drew back and focused its efforts repeatedly on the sensitive flesh, every thrust forcing a quiet moan past Fluttershy’s lips.

The slime soon stopped driving straight for the cluster of nerves within her, and instead thrust itself up to it before holding itself there and running its tip in a spiral motion against the special patch of flesh, starting from the outside and working inward. It quickly retreated back before repeating the process again. Every pass only lasted a few seconds, but to Fluttershy they were the greatest few seconds she had ever experience. A glance down her body showed a small bump in her belly move around as the slime ground itself against her walls. Even as the slime changed its tactics it kept trying to press further into her. She could feel her inner walls beginning to strain from the creature’s size, stretching tight the slime repeatedly plowed itself into her. The sensations she was experiencing were beyond anything she had ever really experienced. She had a toy she used occasionally for when she was in heat, but her experiences with the faux phallus paled in comparison to what this creature was giving her. It seemed to know just when and where to strike, every new attempt at stimulating her sent her pleasure to heights she never knew were possible. She knew that at any moment her pleasure would peak, she could feel it, like a raging river about to breach a dam. Her eyes were sealed shut and her face scrunched up as she struggled to allow the feeling inside her to build, her body tensing up for the coming release.

Then suddenly everything stopped.

She looked down at the slime to see why and was amazed at what she saw. Nearly half the creature was inside her, which was a considerable amount. She could see her belly bulge slightly from how much was in her already. And from what Twilight said the whole thing would try to find its way inside.

Then the dam burst. The thought of having the entire slime inside her sent her over the edge, causing her to scream and arch her back as her orgasm sent a tremendous shock through her body. Her vision flashed white as the surge of pleasure made its way up her spine and into her head.

As if it was waiting for that exact moment, the slime began forcing the rest of itself into her pussy, pressing out against Fluttershy's inner walls even more and making her belly swell. Fluttershy felt every square inch of the slime move as it forced more and more of itself into her, struggling to fit itself into the already tight passage. She looked down and watched from around her swollen stomach as the last of the creature invaded her body. She could feel her lips slowly close around the creature as it sank further into her depths, grimacing at the slight pain the slime caused as it tried battering at her cervix, desperate to breach the barrier.

The mare watched in fascination as her stomach writhed and churned with the slime’s movements. Again she could feel the pleasure rising as the slime continued its struggle, rubbing and pressing against every spot within her as it tried to access her womb.

A movement at the the foot of the bed caught her eye, temporarily drawing her focus away from the act being performed inside her own body. The second slime was sitting just in front of her, watching as she took the first creature within her. It moved forward and reached out for her mound, her lips parting slightly as the slime within sloshed back and forth. In one quick movement it lunged forward and mashed itself against her clit. The previous slime hadn’t bothered with the nub at all, but right now she wish it had. The sudden assault on her button sent a lightning bolt of pleasure through her, causing her to involuntarily clamp down on the thing inside her with such force that the slime was finally able to achieve its goal.

Her cervix was suddenly breached as the slime's forceful pounding and Fluttershy's contracting walls created enough pressure to send the creature into her womb in one quick motion, the bulge in her belly suddenly moving further up her body as it did so. Fluttershy let out a powerful scream as every nerve in her body seemed to explode with pleasure. Again her vision went almost completely blank as her orgasm almost overloaded her senses. The initial jolt soon died down, leaving Fluttershy in a state of euphoria. The feeling seemed to last forever as Fluttershy reveled in the joyful bliss of the most powerful climax she had ever had, coupled with the incredible fullness that she now felt.

Before she could begin to come down from her orgasmic high, she felt a familiar presence making itself known. The second slime was pressing itself into her passage, but instead of starting to piston in and out like the last one, this one went straight for her womb, quickly slithering inside her already abused passage. Fluttershy gasped as she felt it force its way in. Despite being smaller than the other one, it was still fairly large and caused her walls to stretch out again. With the first slime having loosened her pussy already, the second had little trouble making its way into her tunnel, causing her lower belly to bulge out again.

Fluttershy's mind was becoming muddled as the second creature made its way into her fully and began pressing against the barrier that the first slime had passed. Like the rest of the passage, it had been loosened up, but only slightly, forcing the slime to work the opening wide enough again to pass through.

She could feel the first slime inside her, rolling and moving about as the second slime eventually wedged her cervix open far enough to begin slowly worming itself into her womb to join its brother. She watched as her belly swelled up even more as the last of the second slime passed through. Fluttershy just laid there, panting heavily from all the sensations her body was experiencing. Her belly was so swollen with the creatures inside her that she couldn't sit up even if she wanted too.

As she lay in her bed, now drenched in sweat, the sweet little tremors of her last orgasm began to fade. As it did so, the effects of the past several minutes began to make themselves present. Her body felt limp and unresponsive and any attempt to move anything but her head was met with few results. Eventually she gave in, laying her head against one of the many pillows adorning her bed.

Barely a minute later the mare was fast asleep.
