Spike and Moondancer have that awkward couple moment when they both got each other the gift of fertility.

Spike and Moondancer have been together for a few years now and are looking to add to their family. Unfortunately being dragon and pony they can't normally get pregnant.

Lucky for them, Spike knows Zecora, one of the best potion masters in Equstria. If anyone can come up with a brew for them to have a foal it's her.

Lucky for them, no one knows the odds and ends of magic like Moondancer. If anyone can find a fertility spell for them to have a foal it's her.

Though it might have been better if they told each other about their plans before they used the potion/cast the spell.

Contains: Impregnation, Hyper Pregnancy, Rapid Gestation, Growth, Huge Belly

Gifts

Spike looked down at the potion vial in his hands as the train rolled into Canterlot. The snow swirled around the train and covered everything in a thin layer of white, making it difficult to see very far. The potion glowed with a soft pink that made the light green of his palms seem to glow. It was his gift for Moondancer, to celebrate their fifth Hearth’s Warming together as a couple.

He had never expected Twilight renewing her friendships in Canterlot would bring back his feelings for his first crush. Unlike Rarity, where his infatuation had burnt like a magical flame, his interested in Moondancer had smoldered, growing stronger every time he saw her. On his eighteenth birthday he’d worked up the courage to ask her out, and even though she was almost ten years older than him, she’d accepted.

Now they were living together in Canterlot. While Spike missed living with his older sister, being with his marefriend was better. He was even able to use his skills to help Moondancer with her studies and doctorate work, as well as sort her personal collection of books. He’d also gotten a job with the Canterlot archives helping them with the influx of new scrolls about Twilight.

The train lurched to a stop at the station platform. The moment it did, ponies all around him got up and started heading to doors even before they’d opened. Spike just smirked at that, staying back in his seat as everypony prepared to get out into the cold winter air. They were all in such a hurry, trying to get home for the holidays (or maybe just wanting to get out of the stuffy train cabin) but either way, when the doors opened, they flooded out like an undammed river.

Spike put the potion into the pocket of his hoodie as he stood up and zipped it closed. Unlike the ponies who were bundled up in thick jackets with scarves and gloves, he was wearing just the single layer over his t-shirt; one of the benefits of having an internal furnace. Though he did pull the hood up over his spines to keep the snow off his head.

He joined the flow of ponies off the platform and through the station until he reached the streets of Canterlot. It was funny, he had grown up here, but yet Ponyville seemed far more like home then the capital did. He was more or less a small town drake in the big city, but he didn’t mind in the least. He found himself almost skipping along down the street as he went, though he held himself back from that. He didn’t need to knock anypony over with his tail. Again.

Soon he was off the main streets of Canterlot and away from most ponies, the snow from the sidewalk pilling up on the top of his shoes and catching in the turned up cuffs of his jeans. As he turned a corner he spotted the familiar outline of the home he shared with Moondancer. The house was looking much better than when he and Twilight had paid that return visit so many year before: Everything was patched and painted, the windows and yard clean and tidy with a warm glow of lamp light flickering behind the glass. The roof had a line of magical crystal along the edge, flicking through a number of different festive colors.

Spike quickened his pace, not quite running but nor was he just simply walking as he came up to the door. He felt a small tingle of magic in the handle as it unlocked for him. He pushed it open and stepped inside, throwing his hood off his head and sending a rain of snow down over his shoulders.

“Moonie?” he called out, but nopony answered.

He shook his head and walked into the dining room, not at all surprised to find her hunched over the table with her nose in a book. She was only wearing her bathrobe, and it had fallen off one shoulder to give him a glimpse of the warm yellow of her coat. Her hair was in it’s usual style, pulled away from her face with a hair tie, giving her a colorful peak behind her horn.

Spike placed his hands on her shoulders with a gentle squeeze. “What’cha reading?” he asked.

“Starswirl’s Treaties on Magic, newly revised,” she said. She looked up and smiled, her dark purple eyes shining behind her glasses. They always reminded Spike of a pair of perfectly cut amethyst gem stones under a near moonless night, and when she was happy, they looked filled with starlight.

Spike leaned down and kissed her on the nape of her neck, then around to the side. He noticed she was wearing absolutely nothing under her bathrobe, the front of it hanging open and leaving one of her pert little breasts uncovered. They were just under a handful capped by a large nipple and just perfect on her. “I can always introduce you to him,” he suggested.

Moondancer rolled her head, exposing more of her neck to him. “Maybe… mmm, once I finished reading his updated books…”

He kissed up her neck until he reached her cheek. “He’ll be visiting Twilight after the holidays. We could go visit them both.” He took her chin gently in his fingers and turned her head so he could taste her lips. She kissed him back, her eyes slowly closing behind her thick glasses. He could smell the peach scent of her shampoo, and it always made him remember a spring day early in their relationship when they had gone on a picnic to the Canterlot Royal Gardens… only to end up falling into a stream.

“I got something special for you,” he said as they broke apart.

“Did you now?” she asked as she marked her place in the book before closing it. “Well, I got something for you.”

Spike smiled as she stood, the top of her head coming just to the underside of his chin. It put the tip of her horn at eye level, making it easy for him to kiss her right at the base of the horn. “Well, it is Hearth’s Warming Eve. Should we open some gifts early?”

She rose up on the tips of her hooves to kiss him. “Meet me in the bedroom in five minutes.” She then scampered off down the hall, her hooves clicking on the wooden floor and her robe fluttering around her wide hips, hints of her tail showing under the hem of the fabric.

Spike couldn’t help but whistle. There was just something about the way her hips swayed as she walked—it wasn’t anything she ever tried to do, it was just who she was. But hot damn if it never failed to make his pants tight…

Spike reached into his pocket and pulled out the potion bottle. He pulled the cork free with a pop and lifted it to his lips, the scent of freshly fallen rain rising up to tickle his nose. It rolled down his throat in a trail of warmth, thick like a milkshake with the taste of emerald and daffodil. Not bad at all.

He slipped his long tongue into the narrow neck to lick up every drop still clinging onto the glass. The warmth was now rolling in his belly, gathering up and then sinking in, then slipping down until it focused on his balls. He could feel them start to swell in his pants, tingling in the most pleasant of ways as they grew heavier… fuller…

Spike shrugged off his hoodie and draped it over the chair. He worked his shoes off and inspected his well-worn socks, the claws at the tips of his toes finally causing the material to fray.He pulled them off and stuffed them into his shoes, making a note to either patch them (again) or just bite the bullet and order some new ones made. That was a pain as he had to order them from Griffonstone, and the cost of shipping was more than the socks themselves.

After enough time had passed, Spike got up and starting climbing up the narrow spiral staircase that lead up to their bedroom. Moondancer was waiting for him, sprawled out on top of the bed and smiling towards him. She was dressed in only her fur with her hair let down, flowing over the top of her shoulders and framing her face. She’d even changed her glasses, putting away the thick frames in favor of a dainty armless pair that stayed perched on her nose with a little bit of magic.

Spike smiled. His eyes slowly tracked over the lines of her body as he licked his lips. “Now there’s a sight I never get tired of seeing.”

Moondancer’s gaze was hungry as she eyed the thick bulge in his pants. “I can tell.”

Spike grabbed his shirt and pulled it over his head in one smooth motion. He slipped one hand back to undo the button that held his pants closed over his tail while his other worked open his belt. Once both sides were free he pushed his pants off his hips, his boxers following soon after. His long, thick cock bounded free to sway in front of him as a tendril of pre oozed from his pointed tip. With a quick kick of his leg, he sent his pants flying back down the stairs and stalked towards her, his huge, fat nuts burgeoning in their scaly sack.

Moondancer licked her own lips. She rubbed her right hip slowly, tracing the outline of her cutie mark. “Now, my big, sexy dragon, get over here and show me how you use that cock of yours.”

Spike climbed onto the bed, crawling up and over her, close enough that he could feel her warmth. He lowered his head and touched his nose to hers, her breath rolling over the scales on his face. He just held himself there a few moments to take in the beauty of the mare under him. He could smell her freshly applied perfume, one he’d given to her for her birthday. It was made with ground gemstones and made her smell good enough to eat.

He kissed her, allowing his tongue to tease around the edges of her mouth. She wrapped her arms around him and pulled him down tight against her with a tiny moan. Her horn danced with a soft glow of magic, a moment later Spike felt her grasping at his shaft, squeezing at the tapered length. The touch made him purr into her mouth, the magic always feeling so unique when she used it like that.

Moondancer broke the kiss, lust burning in her eyes. “Fuck me… fuck me now.”

Spike’s reply was to lick her vulnerable neck. He shifted his position as she mewled beneath him, moving his shaft up against her legs, her magic gently guiding his shaft until his tip was against her narrow lips. With a soft grunt he slowly pressed forward, the spade-shaped head of his shaft going in easily, pushing her open until he slipped inside.

“Ah…” Whether one of them gasped or both, they didn’t know. Spike held himself there a moment as he smiled down at Moondancer, allowing her to grow used to his size before he started sinking the rest of his length into her. Inch by inch he slid in, his shaft growing wider the closer to the base it got, the ridges on the bottom rubbing against her sensitive flesh.

Moondancer was already squirming. Her hands were pawing at the scales of his back, her fingers running over them without catching. Her legs were splayed out to the side, one hoof kicking as he buried himself inside her, the base of his cock almost twice as wide as the head. He filled her like no stallion ever could, and in the early days of their relationship just entering her was enough to make her cum.

But now, she had the stamina to be good and properly fucked.

They kissed again. Moondancer stroked her fingers over the small spines that ran the length of Spike’s back, and slowly he started to thrust against her, their eyes locked as he did. Moondancer was that rare mare who preferred the missionary position, not for any reason of faith or being a prude, but because it let them look at each other the whole time. She said it made the whole thing all the more erotic. He wasn’t sure how watching his face get all clenched up and squinty was erotic, but it made her happy so he wasn’t going to say no.

With each thrust the warmth in Spike’s balls grew, joined by the familiar tingle of magic deep inside. It didn’t stay there though; it soon moved deeper and deeper into his crotch, making him grunt happily as it felt so damn good. He dug his toes into the bed, using it for leverage as he picked up speed to pound her harder, the whole bed starting to rock under them.

Moondancer kissed him deeply, her hands grabbing the back of Spike’s head to pull him closer and dive her tongue down his muzzle., She moaned loud and long into his mouth as she explored the back of this teeth, her head spinning with need.

Spike braced himself on the bed and rutted her with every ounce of strength he could muster, not holding anything back as he fucked her silly. He could see the lust burning in her eyes, almost glowing behind her glasses. He wrapped his tongue around hers as she squirmed even more beneath him, her arms wrapping around him to pull their bodies as tight as she could

Spike was getting close. He could feel it building deep in his balls, now totally wrapped in the warmth of potion’s magic. He tried to say something, but Moondancer’s tongue kept him from making any sounds but grunts. So instead he slammed deep into her as his orgasm washed through him, running down his whole body until it focused on his cock.

The potion blazed through him in a rush, flooding Moondancer with a potent mix of powerful magic and virile seed. She arched up against him as her own peak followed, sparks of magic dancing between them like lightning. He held himself tight against her as filled her again and again, pumping her womb full of hot, hot cum.

Spike was left panting on top of her as he tapered off. The warmth of the magic faded from inside of him, and slowly he untangled his tongue from hers to smile down at her as their faces glistened with sweat. He gave her one last kiss before rolling off, flopping down at her side and leaving a trail of their mixed lusts between them.

“I love fucking you,” he said softly. He played with the fur on her hip, teasing just outside of her cutie mark without actually touching it.

Moondancer laughed. “And I love being fucked by you!! Although now, I want to show you YOUR present.”

“Oh?” Spike asked, propping his head up with one hand.

A smile fluttered over Moondancer’s face as her horn glowed again. The magic held tight against the tip, growing bright and gathering in an uneven ball. Then with a twist of her ears, the ball of power detached and floated up over her body, hovering just out of reach to circle slowly above them. She then sent the magic diving down into her belly to sink inside with a soft glow on her skin and fur.

She giggled and smiled at Spike. “Happy Hearth’s Warming, hon.”

Spike reached out and stroked a finger over her cheek. “What was that?”

“Oh, just a very powerful fertility spell.” She leaned in to kiss him. “Now we can finally have—”

She stopped when she saw him freeze.

“What’s wrong?” she asked.

Spike’s mind raced as he tried to remember the warnings he’d been given about the potion. If it had been a unicorn spell the two would have counter each other, but a zebra potion? “That… erm, was k-kinda the gift I got for you. I just took a potion I got from Zecora to insure I could get you pregnant.”

Moondancer recognized the name of the zebra shaman Spike had mentioned a few times. She glanced down at her belly, reaching out to find that it was strangely warm.“I’m… not sure if that’s a problem or not. I’m not familiar with the interactions between unicorn and zebra magic...”

Spike placed his hand on top of hers, feeling the warmth radiating from inside her. Squinting, he said pulled a distant fact out of his memories from helping Twilight study. “They amplify each other.”

But that knowledge didn’t help him at all now. He had no way of stopping the combined effects.

Growth

A shiver ran through Moondancer as the warmth grew. It swam around inside her belly, making her tingle in places that she very rarely felt. It was actually rather pleasurable, like she was being teased from the inside of her body.

Lighting her horn, she gently probed at the spells to see what was happening. The magic was still there, laying heavily on her womb yet entwined with what she presumed to be Spike’s potion. The combination was growing stronger by the moment, so she carefully she formed a spell to stop it, pressing the new spell down over the old one.

The growing power flared even stronger.

“OH!” A second climax crashed into Moondancer, juices gushing out between her legs as she let out a high-pitched cry. Spike jumped back with a yelp and pulled his hand away as he saw the soft light in her belly reappear though her pelt.

Moondancer tried to concentrate, to cut off the flow of magic to the spell, but she couldn’t focus through the waves of pleasure. She grabbed the bedding, yanking at it as her tail trashed under her arched body.

“I’ll get help,” Spike said, moving to get out of bed.

“NO!” Moondancer snatched his wrist, squeezing it and pulling him back towards her. “S-Stay here,” she gasped. The glow coming from her belly was starting to flicking and ripple, the power pulling back down inside of her and coalescing into a hard ball. “Don’t spoil this…”

She could tell the spell was still growing, the power increasing and turning inwards, focusing solely on her womb. Soon the glow faded away completely as the waves of pleasure finally dissipated, and Moondancer relaxed back down onto the bed with a shuddering sigh.

“Is it over?” Spike asked. He put a hand back on her belly to find that the warmth was still there, but not as strong as before.

“N-Not yet.” The flow of magic into the spell wasn’t growing stronger anymore, but it wasn’t getting any weaker, either. Yet strangely, Moondancer couldn’t quite feel where the magic was going. The spell was tucked into itself like a turtle in its shell, and she couldn’t sense inside of it!

But she definitely felt something happening in her belly. Something big. She felt her gut wriggle again just in time to feel the skin ripple under her fur, then a short moment later, her womb started to swell. It was small at first, just a growing pressure from deep below her navel, but it was fast enough that she knew that’s what it was. She lightly pressed her hands down more to feel it expanding inside and out.

Spike noticed what she was doing and pressed in the same place, frowning at what he felt. “What is that?”

It was suddenly so obvious.“I’m pregnant!” Moondancer broke into a huge grin. “Spike… we did it!”

It took Spike a second, but when it did, his smile was even bigger than hers. “Oh my gosh,” he gently rubbed her belly. “Oh my gosh!”

Moondancer could still feel it growing under her touch. It was moving forward quickly, and if she had to guess, she was already two months along. She took Spike’s hand and held it in place as her baby bump started to show. “Hold still or you’ll miss it, silly.”

He blinked in surprise, looking down at his hand as it slowly rose more and more with her every breath. “Are you… whoa. I mean, how fast?”

Moondancer moved to snuggle up with Spike. “I don’t know. It could be a few months… or I could give birth tonight.” She pulled him down for a kiss. The magic was still rolling into the spell, yet it left her with a warm comfortable feeling. “Don’t worry, all spells of this nature have safeguards for the mother and the foal. If anything, those safeguards are likely even more powerful now that the effects are amplified.”

But Spike was still torn. “I’m not sure we should just sit back while this happens. We should at least tell somepony, shouldn’t we? Maybe I could send a letter to Twilight—”

Moondancer cut him off with another kiss, this one deep and hungry. Spike melted into her touch as the curve of her belly continued to rise upwards, her navel being pushed along with it.

“It will be fine,” she whispered into his mouth. “Just be here. I want you to experience this with me.”

“Yeah, but if you’re about to give birth…” he paused as the implication of that seemed to sink in.

“The hospital is two blocks away.” With a laugh Moondancer kissed him again, her hands still on her belly, rubbing over it as it showed no signs of stopping. They made out together with rising fervor as the seconds passed, soft sounds of desire escaping both of them.

It was rising up before her very eyes like bread in an oven, the curve of it growing larger by the moment. She guessed she had hit about four months, and the comforting weight was beginning to push down and press her further into the bed.

“This is amazing,” Spike said, rubbing the lower curve of her belly. The skin felt tight under his fingers, yet the fur was unblemished by any stretch marks in her skin. “I can’t believe this is happening…”

“Help me sit up,” said Moondancer. She reached up to grab his shoulder, using it to pull herself upwards. Spike was quick to slide an arm around her shoulder and move up behind her, pressing up against her back and allowing her to put some of her weight on him.

Moondancer leaned back against Spike, leaning back to smile up at him. He returned the smile and leaned down to kiss her as both of their hands moved down to rub her growing belly. It was pleasantly warm under her fur, pulsing ever so slightly but enough that they could feel it on their fingers.

A moment later, Moondancer felt something moving inside of her. It was only the smallest of movements, but she felt it right under her navel. She took Spike’s palm and moved it there, holding it in place as the movement came again.

“There she is,” she said in almost a whisper. “Can you—”

She was about to say more when she felt another flutter of movement down lower.

Then another… and another!

Small movements were breaking out all over the inside of her womb, and it couldn’t have just been from one foal. On impulse, Moondancer cast a familiar spell, one every unicorn mare learned when they were in their teens. The gray glow of magic floated from her horn and drifted downwards before hanging over her belly. The spell spread out, thinning into almost nothing… before a single bright light formed just above her fur. It was followed moments later by second… then a third…

Before long, a whopping seven points of light were floating above her growing belly.

“Oh my…” Moondancer stared at the small moats of light that flickered and danced before fading away. She rubbed her belly with her hand, her ears twitching as she took it all in.

“What were those lights?” Spike asked.

Moondancer wet her dry lips. She just looked up at him and squeaked out a single word. “F-Foals.”

“Foals…”Spike trailed off. “That’s… th-that’s a lot of babies.”

She nodded, letting out a gasp as her growth continued. The force of it was building up under her belly button, slowly pushing it outwards even as the weight of her womb started to settle on her thighs. She had no idea how far along she was anymore, having no idea just how big a mare was supposed to get with so many. Definitely not as far as she’d thought, that was for sure.

Moondancer looked down at her belly as it as it grew ever-larger, rising up under her breasts and starting to lift them. It was curving outwards over her legs, already halfway to her knees and showing no sign of stopping. She ran her hands down over her sides as her bump was started to bulge out wider then she was.

“We’re going to have a family,” she murmured.

Then the spell did something new. There was a jolt as the feeling of the magic reached upwards, past the top of Moondancer belly to concentrate now in her breasts. Her nipples snapped outwards, growing rock hard in a moment and causing her to gasp and moan.

Spike looked down and saw the diamond hard tits capping his marefriend’s breasts. He lifted a hand off her expanding belly to cup one of them and squeeze as they swelled even larger against his fingers. He rubbed and pulled her nipple with gentle care, and his efforts made Moondancer moan even more.

“Whatever you’re doing, don’t stop!” She didn’t want to take her hands off her belly, her fingers interlaced across the lowest point of it, but it was getting harder to reach with every passing moment. She rolled her head back to rest against his shoulder, her breath coming in full, deep inhales that kept her skin a healthy shade.

Spike kissed up and down the side of her neck while cupping and fondling her tits. He relished how the soft flesh deformed around his fingers, even while remaining firm and pushing back against him as they continued to plump up.

Moondancer was in heaven. Spike’s squeezes and rubs only added to the amazing sensation from her expanding belly, and it was all combining to form her third peak of the night. She could feel each breast getting heavier as it expanded, her nipples swelling thicker and fatter between Spike’s nimble fingers. It wasn’t long before his efforts resulted in a sudden trickle from both sides, but neither of them were exactly surprised.

Spike collected a few drops of milk on his finger and took a taste. “Oh, it’s sweet!”

“Let me taste?” She could feel each of their seven foals moving inside her now, wriggling and kicking as they grew. It was caused her belly’s shape to shift and bulge, rarely remaining still from moment to moment. Her fingers were slowly being pushed apart by her belly as it pushed down over her legs almost to knees, yet the realization of that made her giddy for some reason…

Spike collected a few more drops on his finger and lifted it up to Moondancer’s mouth, so close she could smell it. She sucked on the finger and found that her milk did indeed taste sweet, sweet with a hint of vanilla underlying it.

“Mmmm…” she ran her tongue all around his claw and nuzzled the crook of his neck.

Spike slowly pulled her finger free of her mouth with a soft pop, then went back to rubbing at her breasts as they grew even heavier with fresh bounty. They hadn’t stopped getting larger, and now they sank down to rest comfortably atop her mammoth belly. The pressure inside of them was cause small dribbles to leak out, soaking her fur but yet still growing bigger, reaching the size of her head and then some.

The growth of her belly soon pulled her fingers apart, and soon after that, her fingers were far enough that they no longer touched. The weight of her impending motherhood pressed heavily down on her legs, the bed creaking as it tried to hold up her impressive fertility. She couldn’t tell for sure, but she guessed she might have doubled in weight just in her belly alone, and she wasn’t even done growing yet…

A shiver ran down the length of Moondancer’s spine, and the power of the spell suddenly increased in a sharp crescendo that pushed her over the edge. She cried out as her belly grew a few more inches in a single moment before the magic at last quieted down, the mighty surge at last, coming to an end. She slumped down against Spike, letting him take all of her now considerable weight against him.

“That was amazing,” she said, almost in a whisper. She felt better than she could ever remember, but now she also felt more tired than she could remember. She sagged heavily against Spike and sighed, her eyes fluttering closed.

All Spike could do was nod, his hands dropping down to feel her belly. Her pelt was soft under his fingers, soft yet firm at the same. He just stared at the results of the magic, not quite able to really comprehend just how large she had become. The only thing he could compare it to was Zecora’s culdron, but even that wasn’t quite big enough.

He pulled his eyes away and looked at her. “We should probably go get somepony,” he suggested.

Moondancer yawned. “In the morning…” Slowly she drifted off, their unborn children doing the same. This wasn’t what she had expected when the night started, but it just felt so right to her. Being nearly at term with seven children… it was more than she could have ever asked for.

Spike sighed. He knew they’d have to see a doctor in the morning to see when she was due, but perhaps sleep was for the best. Right now, they could relax and fall asleep in each other’s arms, dreaming of what the next day would hold for all nine of them.
