Twilight had borrowed the boulder costume from Rarity and was now safely inside it. She was monitoring a test subject for a new set of experiments she had planned. Said test subject was likely to react with hostility if he saw her, hence the costume. However, her next experiment required her to interact directly with the test subject. Lucky for her, she had devised a genius plan in order to draw the subject close to her hiding spot.

“Hey, some idiot left perfectly good gems lying around,” a male voice said with a laugh. “Looks like their loss is my gain.”

‘Perfect~’ she thought to herself, watching as Garble walked up to the trap.

“Alright, rubies and amethysts, my favorites.” He grinned, picking up one of the purple gemstones and munching away. “Mmm, I should find the schmuck who lost these things and laugh at ‘em.”

“And now!” Twilight cast her spell, a cloud of sleeping dust exploding out of one of the gems.

“What the actual fuck!” Garble coughed out, his wings trying to blow the dust away. His nostrils flared, taking in the dust. He swayed on his feet for a moment. “Oooh, nighty night,” he muttered, collapsing to the ground and letting out a deep snore.

“Success!” Twilight grinned, teleporting out of her costume. “Now...” she looked down at Garble. “Let’s get you back to the lab.” She smiled, picking up the drake in her magic and teleporting the two of them away. When the two of them reappeared, they were in her lab, a magic soundproof bubble surrounding the room in case someone got loud during the experiments. She put Garble down on a slab, tying him down as she put on her safety goggles, lab coat, and put her hair up in a bun.

“Bwa...?” Garble groaned, opening his eyes slowly.

“Oh, you’re awake already,” Twilight commented, snapping a rubber glove over her hand. “Seems that dragons are able to clear things out of their body faster than ponies. I’ll make a note of that,” she said, using her magic to scribble onto a piece of parchment.

“The hell!?” he growled, thrashing around. “Let me outta here!”

“If I did that you’d try to claw my eyes out,” she pointed out. “Now calm down, I won’t hurt you.”

“I said lemme out!” he roared at her.

“If you don’t stop that, I’ll gag you,” she warned, picking up a ball gag with her magic. “Now, what’s it going to be?”

“The hell is wrong with you lady!?” he shouted, snorting a puff of black smoke.

“What’s wrong here is that ponies know very little about dragons,” Twilight replied, putting the gag down next to her. “That’s something I’d like to correct. So, I’ve decided to run some experiments and learn about dragon biology.”

“Why don’t you just use that runt of yours?”

“I’ve learned everything I can from Spike,” she answered, sighing. “But now I need a more mature dragon for my experiments. And that dragon just so happens to be you. Look, I know you’re not a fan of ponies, but I promise to make this worth your while.”

“Oh yeah? How’s that?” Garble asked, glaring at her.

“How does a veritable gem buffet sound?” she asked, pulling out a large ruby. “There are certain perks I have as a princess. So, do you like what you’re hearing?” She asked, holding the gem out to his mouth.

“Y-yeah...” he nodded, licking his lips, staring at it.

“Does that mean you’ll behave if I let you down from there?” Twilight asked, pulling the ruby close to her chest. “I’d like it if I could make this as comfortable as possible for you.”

“Give me the ruby first.”

“Alright, I can do that,” she walked up to the dragon, holding the ruby close to him with a smile on her face. “Eat up~” she sing-songed. He ate it up, letting out a satisfied moan as he did. “Are you ready to cooperate?” she asked, putting a hand on one of his bindings.

“Only if you keep feeding me.”

“I think I can manage that,” Twilight said with a giggle, letting the dragon down. “There, now let’s begin with a small body exam.”

“Uh huh...” he sat up, shaking his head.

“Great!” she cheered, a bright smile on her face. “And would you mind if I asked you some questions while I do the exam? It’ll help me learn more about you and your species,” she said as she stood close to him.

“Whatever...”

“Thank you very much,” Twilight said, having some equipment float around her in her magic. “Can you open your mouth please? I’d like to take a quick look at your teeth.” He rolled his eyes, openings his jaws, looking at her expectantly. She took a dental pick and a penlight, examining his teeth closely. “Hmm, it seems that as dragons grow their teeth become even sharper. I’m going to guess that aside from gems you eat meat. Is that assessment correct?” she asked, using her magic to write notes.

“Yup.” he chomped his mouth closed, grinning at her.

“Then I’ll start adding meat to Spike’s diet,” Twilight replied, continuing to write notes. “I do want him to develop properly after all. Anyway, turn around and spread your wings, I’d like to examine those next if you don’t mind.”

“Whatever you want.” he turned around, spreading his wings out.

“It seems a dragon’s wingspan is proportioned differently than most ponies,” Twilight observed, running a hand along the top of his wing. “Though, given your size and build, I would expect as much.”

“I am strong.” He grinned posing like an idiot.

“I know you are,” she assured him, rubbing his wings with both hands now. “You were able to push a large boulder off yourself with only the help of a baby dragon. That’s impressive.”

“H-hey! You shut up!” he looked back at her, growling.

“I was trying to pay you an actual compliment, Garble,” Twilight assured, rubbing the base of his wings to get a feel for his flight muscles.

“Oh that feels good...” he moaned softly, twitching his wings.

“It seems ponies and dragons share something in common after all.” She giggled, rubbing a little harder for him. “The bases of our wings are sensitive as well.”

“Yeah...keep that up...” he smiled, leaning into her touch.

“I can do that,” she whispered up to him. “You did ask nicely after all~” She continued rubbing, watching Garble with an amused smile.

“Ooh...” he closed his eyes, tongue hanging out of his mouth.

“So Garble, what would you say about moving on to my next test?” She asked, pressing her chest against his back. “I think you’ll like it as much as this.”

“Okay...” he nodded, a shudder passing through his body.

“I’ll just need you to turn around and face me,” she said, giving his wings a final squeeze. He did as she asked, looking down at her with lust filled eyes. “Why are you looking at me like that?” Twilight asked, suppressing a smirk as she pulled her safety goggles off.

“Because you're hot... for a pony...”

“Well thank you, Garble,” Twilight said, running a hand up and down his torso. “And despite our less than ideal meetings, you’re a very handsome dragon.” He smiled, licking his lips. “Now, why don’t you sit down and I’ll get us started on the next test?”

“I’d love to...” he sat down on the slab, keeping his eyes on her.

“That's what I like to hear,” she beamed, her magic’s aura surrounding his crotch. “Let’s see if this works,” she muttered, beginning to send vibrations along the drake’s groin area. He let out a long moan, bucking his hips. “Do you like that, Garble? Are you going to get hard for a pony like me?” she cooed, staring into his eyes.

“Y-yes...” he admitted, looking back into her eyes.

“Then what are you waiting for?” She teased. “I want to see what a dragon’s penis looks like.” He blushed, feeling himself rise up into view. “Ooh, I like what I’m seeing, Garble,” she said, reaching out and giving the drake an experimental stroke. “You’re as long as a stallion but not quite as wide. Though those small ridges will more than make up for it. And that tapered tip must make penetration a cinch.”

“Hey! I’m bigger than any lousy pony!” Garble snorted, looking a little insulted.

“Considering the sizes dragons can reach, you will be,” she said, stroking him slowly. “There’s no need to be insulted though, I think your penis is perfect as it is.” He shuddered a little.

“We need to get you out of those stupid clothes first,” he countered.

“Not yet~” Twilight giggled. “I need to collect a sample of a dragon’s seed before we do anything else,” she continued, getting on her knees so she was at eye level with Garble’s erection. “I hope you don’t mind.”

“Oh ome on!” he frowned, reaching down to just cut her clothes off.

“That’ll cost you a few gems,” Twilight said with a frown, her breasts bouncing as her ruined bra and shirt fell to the ground.

“Totally worth it!” he grinned. “I don’t know why you ponies wear clothes anyway.”

“I could explain it for you later if you’d like,” Twilight offered, giving Garble’s tip a quick lick.

“Y-yeah...” he moaned, grabbing her head, starting to push past her lips. Twilight allowed Garble to take control a bit, swirling her tongue around his tapered head as it passed. She took note of his scent and taste, it was slightly spicy, something that didn’t disagree with her tastebuds. He began to move his hips, brushing the tip of his tail against her nipples. Twilight let out a moan of her own, looking up at Garble in surprise as she gave him a powerful suck. “You like?” he asked, letting out a purr. Twilight nodded, using a hand to rub the base of his tail.

Garble let out a moan, moving his hands down, roughly squeezing her breasts. Twilight let out her own moan, sending vibrations along the drake’s erection. Her tail flicked back and forth and her wings stiffened, a sure enough sign of her own growing arousal. His tail snaked its way into her panties, rubbing her slit. Twilight’s wings stiffened completely, and she looked up at the drake as if begging for him to continue. As if to entice him, she started flicking her tongue across the ridges that lined the top of his member.

“That's it you horny little pony.” he flicked her clit, sliding the tip into her. Twilight let out a muffled scream of pleasure, starting to bob her head in time with his thrusts. She looked up at him, the hand on his tail giving it a fond squeeze. He picked up speed, pinching her nipples, scratching her breasts lightly. She shuddered under his rough treatment, locking eyes with Garble as she battered her tongue against him while her juices started covering his tail. Her one hand started squeezing and stroking his tail, while she placed the other on his thigh to better brace herself.”You like that?” he growled, twisting her nipples. “Master can give you so much more.”

“Mmmph!” She cried, muffled by the member in her mouth as her body trembled. She locked eyes with him, nodding enthusiastically while she squeezed his tail and thigh.

“Good girl~” he cooed, making her deepthroat him, digging his talons ever so slightly into her supple tit flesh. Her body slackened slightly, struggling to keep her head bobbing while her wings twitched wildly. Every time his hips met her muzzle, she nuzzled Garble slightly, showing him she was still aware of what was happening. “That's it, take it like the slut you are!” he commanded her, giving her wings a squeeze.

“Mmm,” she moaned, closing her eyes as she squeezed Garble tighter, forgetting at the moment that she was supposed to be running a scientific study.

“H-here it comes... you better swallow it all!” he threw his head back with a roar, climaxing hard. Twilight let out a muffled scream as she let out a torrent of marecum all over the drake’s thrashing tail. Her mind dimly reminded her the purpose of this, lighting up her horn to catch a portion of the drake’s seed. The rest, she swallowed greedily, thoroughly enjoying the spicy taste as seed coated her tongue and throat. “I’m totally keeping you...” he smiled dumbly, looking down at her. Once his orgasm was finally over, Twilight pulled off of his member with a wet *pop*, looking up at him with her own tired smile.

“There’s room at the castle for you~” she said with a pant, putting the cum she caught in a clear container with a blank label. “You could have your own room, or you could just share mine.” She winked at him, standing up on shaky hooves.

“What are you talking about you’re mine now.” he grinned, licking his licks. “Just wait until the rest of them find out I turned one of the pretty pony princesses into my personal fuck toy.”

“Sorry, but I have my responsibilities here to think about,” Twilight told him, putting the cum container into a cooler. “But… if I wasn’t a princess I’d totally consider just going with you to the dragonlands.”

“Who said you had a choice?” he asked, grabbing her horn, narrowing his eyes.

“I did,” she said, narrowing her own eyes at him as her horn sent an electric shock through the drake. He let out a yelp but didn’t let go, starting to squeeze it. “Grr, if that’s the way you want to play it,” she warned, struggling to pick the dragon up with the pressure he was applying to her horn. She slammed him back down, straddling him and glaring at him. He bared his fangs, swiping at her face. She moved her head, just barely getting a scratch while she punched Garble right in the throat. He let out a strangled cry, grasping at his throat pathetically. Twilight took that as her opportunity to levitate Garble off the ground, wiping blood off her cheek. “Are you going to stop trying to kidnap me now?” He nodded his head quickly, still trying to breathe. “Good, because if you try anything again, I’ll turn you into a pony,” she warned. “And I can do it too,” she concluded, setting him back down on the slab.

“H-help...” he begged weakly, pointing at his throat.

“Okay, I’ll help,” she said, sounding a little worried as she cast a healing spell on his throat and levitated a glass of water over to him. “There you go, that should make things all better.”

“T-thanks...” he coughed, guzzling the water down.

“You’re welcome,” she said with a sigh, sitting down across from the dragon. “You know Garble, I was really about to change my mind about you. Like, maybe you weren’t as much of a jerk as I thought. You were answering questions easily, and you gave me the best orgasm of my life. But then you ruined it by attacking me and attempting to kidnap me.”

“Yeah well... I don’t need your approval.” Garble snorted, turning away from her.

“Can you just tell me why you tried the whole kidnapping thing?” Twilight asked with a frown.

“I’m tired okay!? Tired of being at the bottom of the barrel. Tired of being a nobody...”

“...I don’t think you’re a nobody,” she offered, getting up and sitting next to him. “You’re obviously strong and like I said, you’re a pretty handsome dragon,” she finished, patting the top of his leg.

“You’re just saying that...” he frowned, looking away from her.

“No, I’m not,” she said. “I’m sure you can find a way to not be at the bottom of the barrel. Maybe you just need to stop worrying about coming off as super macho all the time and just find some things you enjoy doing. Like, finding a hobby.”

“What’s a hobby?”

“It’s something that you can do in your spare time,” Twilight explained with a giggle. “There’s a ton of examples of them too: reading, fishing, going out on hikes by yourself or with friends, and plenty more. I could show you a book that could give you some ideas.”

“Er...what’s a book?” he asked, looking genuinely confused.

“I’ll show you!” She cheered with a squee, grabbing the drake’s claw with her hand and teleporting them to the library in the castle. “These are books!” she beamed, waving a hand to all the rows of bookshelves.

He pulled one out, flipping through to a random page. “What is this stuff?” he asked, squinting. “All those little line thingies are making my head hurt.”

“That’s writing, those line thingies are words and sentences. I can teach you to read if you’d like,” she offered, pulling out a book that helped teach the basics of reading.

“You’d do that.. Even after all that... stuff?” Garble asked, looking down at her.

“Garble, I believe in giving others second chances,” she said, smiling as she put a hand on his side. “Even someone who’s done “stuff” like you have.”

“Um... p-Twilight... can I stay here? With you?” he asked with uncharacteristic shyness.

“Of course you can,” Twilight replied, hugging his side tightly. “It’ll give me plenty of time to teach you to read.”

“Thanks.” he smiled, hugging her back.

“And that's how your daddy and I met!” Twilight recounted with a smile, looking down at the small foal in bed. Of course, she had left out the sex part, not like her children ever needed to hear that part.

“Wow, so daddy didn’t know how to read at some point,” the foal said in awe, looking between her two parents. “I can’t believe it, you two read together all the time!”

“Yeah, daddy had a hard time fitting in,” Garble chuckled, ruffling the little kirin’s mane.

“And look at you now, the captain of my personal guard,” Twilight beamed, squeezing the dragon’s side. “The armor really suits you.”

“Thanks.” he smiled, wrapping his tail around her leg.

“I’m only stating the obvious,” she told him with a wink as she turned back to their daughter. “Now you go get some sleep, Honey. Daddy and I are about to go to bed too,” she concluded, snaking a hand behind Garble and squeezing the base of his tail out of the kirin’s line of sight. Garble kept in his moan, his stoic look staying on his face.

“Okay,” the kirin nodded, a fanged smile on her face as the two walked out of the room. Once they were out in the hall, Twilight pulled Garble into a kiss.

“I’m about to start my heat cycle,” she whispered in his ear. “Wanna see if we can give Lavender a little brother or sister~?”

“I was hoping you’d say that~” he grinned his tail sliding into her pants.

“Mmm, I am gonna ride you until all your scales fall off~” she purred, holding onto the drake and nuzzling him.

“And I’ll screw that brain of yours out.” he reached up, poking her forehead.

“Faust, I’m so glad I decided to make you my test subject all those years ago,” she said, teleporting them to their room. “I love you, Garble.”

“Who knows where we’d be if you hadn’t.” he smiled, looking into her eyes. “I love you too, Twilight.”

“Why don’t you show me how much?~” she said, her clothes disappearing in a flash as she fell onto the bed. “Give your pretty pony what she wants.”

“Why of course my dear.” he licked his lips, casting off his armor, climbing ontop of her.

“So, are you going to be a loving husband, or rampaging dragon tonight?” She asked, rubbing the base of his wings as she stared deep into his eyes.

“I dunno, what does my beautiful mate want tonight?” he asked, staring back into hers.

“Mmm, both sound good to me,” Twilight admitted, her tail flicking and brushing against his own. “Well, we could always do that thing that you really love,” she offered, giving him a peck on the lips.

“Haven’t done that for a while.” He grinned, licking her neck.

“I know, too long if you ask me,” she replied, shuddering and exposing more of her neck to him. “Good thing it’s our day off tomorrow. Neither of us will be walking right in the morning.

“Let’s make a baby.” he rumbled, nipping at her neck.

“Yes~” she moaned, rubbing his wings more. “I want to fill Equestria with our little kirins. Come on, make me a mommy again. I need it so bad~” she pleaded, squirming under him.

“As you wish my princess.” he grabbed her hips, thrusting hard.

“Ahhn!” she moaned, her wings flaring out beneath her. “That’s it, keep doing it like that you sexy drake!”

“You're still so tight...” he groaned, grabbing her breasts, digging his claws in.

“Lucky for you, I’m an alicorn,” she said after a long moan. “We’re extra sturdy and resilient compared to other ponies. I told you about the time I was punched through a mountain, didn’t I?” She asked, using her magic to vibrate the base of his tail while she rubbed his wings.

“Oh yeah... keep doing that...” he moaned, picking up speed.

“As if I’d stop,” she moaned, chuckling as she kept the magic going. She leaned up, kissing the dragon. He kissed her back, moving a hand up to rub her horn. “You really do know all my spots,” she husked, pulling away only to crash her lips against his again.

“I’m a quick learner,” he chuckled, leaning down, nipping at her breast,

“Oh yeah, that’s the stuff,” Twilight panted, her fluids dripping onto the bed. “Dragon teeth are the best,” she mused aloud, squeezing Garble’s flight muscles fondly. “Those flat ones stallions have just don’t cut it.”

“Always a pleasure to be of service.” he chuckled, clamping his mouth around her nipple, giving it a suck.

“Mmm, you really do have a fixation on my breasts,” Twilight panted, removing one of her hands from his wings and stroked the fin atop his head. “Though, with how sensitive they are, I’m not complaining. I love seeing you sink your fangs and claws into my breasts.”

“As long as it doesn’t hurt you. Remember that time they called the guards on us?” Garble asked, pulling away to look at her.

“I remember cumming super hard as the guards pulled you off me.” Twilight giggled, still stroking his head. “Though...you did leave a bit of a mark that took some time to go away.”

“And I remember spending the week in a cell.” he chuckled, biting down on her nipple, rolling it between his teeth.

“I hope you’re not complaining,” Twilight moaned, increasing the speed of the magical vibrations at his tail. “It wasn’t easy sneaking in that dominatrix outfit while you were being held there.”

“Who's complaining? That thing makes you hella sexy~”

“Want me to put it on and make you wear that collar and leash when we’re done here?” she asked, kissing the top of Garble’s head and wrapping her legs around his waist.

“Heh, think you’ll be able to with the bloating I’m about to give you?”

“Only one way to find out~” Twilight purred, bucking against him. “Either way I’m putting that collar on you. You’re one adorable pet.”

“Yes ma’am” he grinned, pinning her down, going as hard and fast as he could without breaking the bed.

“Yes!” Twilight cried, throwing her head back. “I love it when you get so rough! Come on, pound into me! Claim me you big, strong dragon!” He let out a roar, throwing his head back, firing load after load into her. Twilight let out her own scream of ecstasy, holding onto the dragon as tight as she could while her inner walls milked him for all his seed. Twilight bucked against him slightly while her tongue lolled out of her mouth, her wings twitching behind her.

He chuckled, rubbing her swelling belly. “We’re gonna have a brood at this rate...”

“Good, I want to show ponies and dragons what happens when they come together,” she said giving him a quick peck. “Plus, we wouldn’t want our little Lavender to get lonely, would we?”

“Of course not.” he kissed her back, rumbling happily. He moved off her, snuggling her close, wrapping his wings around her protectively.

“Hoping for a boy this time?” Twilight asked, wrapping her own wings and arms around him. “Or do you want another little daddy’s girl?”

“I’m hoping for a boy this time,” he admitted, “Teah 'em how to hunt...”

“Mmm, I think that’d be nice,” she said, nuzzling against his chest. “I can picture you letting our son ride around on your shoulders as you teach him to be a proper dragon.”

“You’ve already ponied up Lavender,” he accused, poking at her stomach.

“I’d like to think I’ve let her get the best of both of us,” she countered. “I can’t help it if she loves learning magic as much as I do.”

“If you say so.” he chuckled, nuzzling into her chest, closing his eyes.

“Good night, my sexy dragon captain,” Twilight whispered to him, yawning and closing her own eyes.

“Good night my smexy pony princess...” The two settled into their embrace, content to drift away into dreams about the new addition to their family they would soon have.
