Author's Note

Tinker has changed a little bit since I wrote most of this story, but I owe you guys a Luna chapter before it's over!!

So I'm gonna use one of his newer traits in this chapter... Tinker, being a hybrid, is able to swap between being either his usual self, a pony, or a dragon, just like he's able to swap his gender back and forth. Male dragon? Female pony? Sure!

And so on, I guess. Dragon tonka shows up in the story I wrote with Ember, but that's an anthro RP, and this one ain't.

Also, y'all are horny but I love you 💙

Dragon Taming with Luna

Tinker groaned a little bit as he began to wake up, feeling something hot, wet, and strong squeeze his cock. his shaft firmly throbbed in response, and then he became aware of the weight on top of him as he finally forced his eyes open. To his surprise, Luna was laid on top of him, his cock knotted inside of the princess who seemed to be asleep. He began to blush warmly at the sight, and he hesitated a little before slowly running his paws down to her flanks, which he grabbed so he could feel her soft ass for himself.

But then she opened her eyes. She began to smirk as she looked up at Tinker, finding that he was awake, and her voice slurred somewhat as she quietly hummed "Theeere you are....~" in a teasing tone. Gritting her teeth a little in an attempt to stay quiet, Luna slowly sat up in Tinker's lap, squeezing his cock tightly. "And don't you feel incredible...~" she quietly hissed.

Tinker nodded sheepishly, his voice a little bit shaky as he said "Y-Yeah..." He squirmed slightly beneath Luna, but he was taken by surprise as the princess began to stand up, pulling off of his knot and then shivering as she let the rest of his cock slide out of her.

"Good..." she hummed softly, before twitching a little as his flare popped free from her marehood. She shuddered, but then she stood herself tall on the bed, shaking herself a little to straighten out her wings. She looked down at Tinker, and she began to smirk as she said "You ready, my little dragon?"

A shred of hesitation, but then Tinker quickly nodded, putting on a shy-yet-excited smile. His eyes went to Luna's horn as it began to glow, and then, she set off a teleportation spell. When Tinker opened his eyes, he wasn't sure where they were... it was too dark to see anything, but then bright blue flames began to ignite in a circle around them. Tinker found himself- and Luna- in a rounded room, seemingly underground judging by the smooth carved stones making up the walls. There were a few doors leading out of the room, but the room itself had a few scatterings of pillows and blankets, some looking much older than others.

Tinker began to blush, and Luna spoke first as she said "I prefer doing certain things away from my bedroom... now, dragon, let me see your true form..."

"Oh, well, I'm... I'm not a dragon, at least, I mean, my mom was, but I'm only half dragon, so I-" Tinker sheepishly said, until Luna closed the gap between them and touched a naked hoof to his lips.

"Shhhh..." she said, as Tinker had thoughts of how pretty she looked without her gear rush through his head. In that moment, he realized what Luna was getting at, and he began to blush deeper as his eyes widened a bit. "I spend my day surrounded by big, burly stallions, I know a dragon when I see one..." Luna growled, pouring a seductive tone into her voice.

Then, she stepped back. Tinker's voice shook a little bit at first, but then he made a cute little growl, his horns lighting up as he said "F-Fine, princess, so you're caught me... b-but I've already lay claim to your sister, and... I uh, you're next on my radar..."

Luna's grin began to widen as she said "Is that so, you beast of the dragon lands? Not even in your true form could you hope to be strong enough to defile the princess of the night...~" she hissed, her voice both playfully hostile and yet aroused at the same time.

Tinker's cock bucked underneath him, but as he shivered, he closed his eyes, and he set his magic into motion. The stallion's body began to glow as his magic set to work, burning away all of his fur as his skin grew thicker, developing reptilian scales that kept his chocolate coloring.

His wingspan grew larger as his wings spread open, and his body shifted as he adopted the structure of a dragon. Rather than a dragon tail on a pony skeleton, he now had a proper dragon body, that gradually tapered from his tail to his midsection and then to his snout. His snout became more pointed, and his horns grew longewr and more swept back, while his ears became more like a dragon's ears.

His hair was gone, but now he had a ribbon of dark brown running from his head all the way to the tip of his tail, taking place of what had been his mane. His tail was longer, he now had the hands and feet of a dragon, and he even grew a bit larger in size, with more muscles underneath his skin, which did nothing to hide them like his fur did.

As Luna watched, almost salivating at the sight, Tinker's balls grew larger and heavier, and he kept his sheath as well. His cock, however, lost the shape of a pony's stallionhood. Now, it was pointed like a dragon, with ridges along the underside that ended with his thick knot. Below the knot, his cock remained just as thick as it disappeared into his sheath, and Luna watched with a shiver of arousal as a bulge passed from his sheath to the tip of his cock, emerging in the form of a splurt of precum that splashed the cool stone floor.

Tinker opened his eyes, which were now those of a dragon, and he smiled, exposing his sharper, pointed teeth. His confidence soared as he looked down at the shivering blue mare, but she surprised him as she lit up her horn, grabbed him, and pushed.

Tinker let out a yelp, but he couldn't stop Luna as she pushed him back into a pile of pillows. He struggled against her magic, but Luna pinned down all four of his legs, and even his wings to the floor as she stepped between his hind legs. Gazing hungrily at his cock, she slowly laid down to bring herself level with it, throwing him a halfhearted glare as she said "T-This is the monsterous appendage you planned to use on me!?"

"H-How terrible, for a princess t-to..." she said, but her voice trailed off as she worked her snout beneath Tinker's balls, where she took a deep breath of the dragon's strong scent. As a reaction, the mare actually moaned a little, her wings snapping halfway open as shudders ran through her. "T-To fall victim to such an... awful..." she struggled to say, while beinging her snout close enough to press her tongue to Tinker's knot.

He struggled against her magic again, growing impatient, but Luna held him down seemingly effortlessly as she slowly dragged her tongue up his cock, tasting each of his ridges and lapping up his precum as her wings gradually opened all the way. At the tip, she paused, her voice even shakier as she said "Y-You should... be ashamed for... thinking you would be able to force me onto this thing..."

And yet, then, Luna closed her mouth around the tip of his cock, and she slowly sank her head down onto his cock, making Tinker quietly hiss and arch his back a little. Slowly, Luna took his entire cock down her throat, the princess letting out weak moans as she let his shaft bulge out her throat. Soon enough, her lips kissed his knot, and she pulled away from him so she could stand up on shaking legs.

Tinker blushed as Luna turned around and stepped overtop of him, putting her heavy teats right above his snout. "I-I'll do what I must to suffocate this beast...!" she cried, as if she wasn't already aware that Tinker had magic that ensured his access to fresh air. Luna laid herself down on his chest, and Tinker welcomed one of Luna's nipples into his maw, latching onto it and starting to suck as soon as she smooshed her teat against his snout.

She cried out a little, but then it was muffled onto his cock as Luna took it back inside, this time plunging straight to his knot. She began to bob her head on his cock, suckling firmly on him, and to her delight it resulted in the shaft throbbing and twitching much more, which meant twice as much of his precum gushing into her maw as she sucked him off.

At the same time, warm milk flooded Tinker's maw as he began to drink from Luna's heavy teat, while he also let his tongue snake out to massage her nipple and coax even more of her milk out of her. It seemed to have quite the effect on the princess, because the more he ground his tongue against her, the noisier she got, and the less she was able to focus on sucking him off.

And to him, it was worth it. After enough teasing, it seemed Luna snapped, and she suddenly pulled her flanks away as she pulled off of his cock, crying out a shaky "Fuck~! T-The beast is draining my milk, a-and I can't stop him~!"

Then, Luna let herself collapse onto Tinker again, muffling herself with his cock down her throat before she sat her other boob down on his snout, giving him fresh milk to drink as he eagerly set to work pleasuring her other nipple instead. By the time he had drank as much milk as he did the first time around, Luna was quivering and twitching on top of him, and he could feel the heated wetness of her pussy dripping down his head as he massaged her boob with his tongue.

Luna wasn't even sucking him off anymore. She couldn't bring herself to pull off of his cock, only push against his knot as she struggled to handle the sensations of Tinker so eagerly draining her milk. She managed to summon the willpower to lift her hips, but this time, as soon as her nipple pulled free from Tinker's maw with a pop, Luna sat right back down, except this time she mashed her pussy against his snout, gasping with pleasure as the orgasm she was holding back nearly overwhelmed her right then and there.

But she couldn't handle what came next. Tinker, growling seductively, opened his maw and attacked with his tongue, plunging the thick, warm, wet organ deep inside of the princess. He wormed it all the way to her cervix, and as his tongue met the end of her pussy, it began to compress inside of her tunnel, and Luna came.

Tinker's tongue was crushed by the blue mare's pussy as she loudly cried out around his cock, gripping his ass and shoving his knot into her maw in an attempt to muffle her moans. It worked, somewhat, but she still couldn't stop herself from twitching and squirming as she rode out her climax, which Tinker gleefully made much harder on her by squirming his tongue into her and hungrily lapping at her inner walls.

His tongue was coated in her juices by the time her orgasm began to fade, and she was silently thankful that he stopped eating her out as her orgasm gave out, leaving her sagging on top of him. Slowly, she pulled off of his knot, sucking in a breath once she managed to free his cock from her throat.

"F-Fuuhhh... d-damn... I was... not expecting... ahhh! T-The tongue...~!" Luna cried, twitching midway through her sentence. Once Tinker realized it was his tongue that she was referring to, of course he had to worm it into her some more, right? He chuckled faintly as Luna stumbled away from him, finally pulling his tongue free from her pussy as she squeezed it tight.

As soon as it pulled out, the mare spun around with a red blush, pointing at Tinker as she said "Y-You! You... fiend! I-I bet you think you've got me in your grasp now! You must think..." she said, as she began to walk closer to Tinker again. Her magic gripped him, pushing him back so he was sitting up a little bit. "That I'm... going to do whatever you want..." she continued, while straddling his lap.

The princess hooked one of her legs over Tinker's thigh, and she left her other hind leg be, planted between his tail and his other leg. She wrapped her front legs around his chest, speaking to his neck as she said "And... that's wrong. I'm going to tame you... and to prove it... I'm going to ride you, but you cum when I say you can~". Luna's horn lit up, and Tinker shuddered as he felt magic sink into his cock, making it twitch hard and splatter Luna's folds with a spray of precum.

Tinker shuddered, suddenly wearing more of a nervous expression, but then he was distracted as he felt the mare's drenched folds envelop the tip of his cock, before Luna thrusted, stuffing his member inside of her. Ridge after ridge disappeared inside of the princess, as she took his cock effortlessly. She moaned as his knot squished against her outer lips, and her body quivered against him as Tinker reached out, grabbing onto her hips.

"Go ahead, dragon... feel your ruler's flanks... squeeze the hips that you're not allowed to defile with your s-seed...~" Luna groaned, as she began to slowly ride his cock. She lifted herself until only the tip remained inside, then she sank back down until her pussy pressed against his knot, then she rose again for another thrust... his ridges felt wonderful dragging against her inner walls, and it made it extremely hard to talk as she leaned against his chest.

Somewhere in a land known as Derpibooru, the secret key 3021674 might help convey a few things.

As Luna rode his cock, Tinker could feel his orgasm rising, and yet... it never ignited. By the time he felt like he was going to cum, Luna was riding his cock with passion, ramming his shaft into her, and yet he just... couldn't... cum. He tried, of course, flexing his cock, bucking against her, even shoving her down onto his hips a few times, but nothing seemed to help.

And Luna only made it worse as she came. When she hit an orgasm, she cried out with pleasure as she collapsed into Tinker's lap, and this time, she took his knot inside of her. As the bulge popped inside of her, the tip of Tinker's cock nudged its way into her womb, flooding it with a thick gush of precum, but nothing more. Tinker couldn't escape the intense milking clenches of Luna's pussy, her body begging him to fill her womb with his hot, thick dragon nut.

But he couldn't. He could only squirm and pant with tension as Luna ground down onto his cock, moaning loudly almost as if she was trying to make him jealous... and well, it was working. It wasn't fair, either. When Luna's orgasm was over, she giggled, her hind legs twitching as she slowly pulled up off of his cock.

Once his knot popped out of her, Luna sat down against it, quietly giggling as she began to grind down against his cock. Her voice was shaky and breathy as she hugged him close, talking past him since his head was over her shoulder. "That's it... I can feel how pent up you're getting... how badly you need to cum... but you can't. You're mine... mine to play with... mine to tame... it feels so much better riding a dragon when they're desperate for release, you know~" she hummed, squeezing his cock tightly as she gyrated against it.

Tinker didn't understand it. Why was she being... mean? Sure, it was hot, concerningly hot, actually, but still, what gives? She gave him such a hard rutting in his dreams, and yet... what was going on? Luna slammed her hips down into his lap, ramming his knot inside of her, then she clamped down tight as she slowly pulled off, pulling his cock out of her as she took a few steps back to admire her work.

Luna licked her lips hungrily as she admired the shivering, panting dragon... he was a wreck, sweaty, his cock twitching and spurting precum, his balls so large and heavy with pent up seed that they were starting to slide to one side of his tail. She giggled at him, showing off her snarky smirk as she said "What? Is it harder than you thought it would be to claim a princess, to hold her down and defile her with your monsterous essence~?" She croned, while swaying her flanks back and forth.

He was starting to look annoyed... conflicted, even... good... she could feel deep magic beginning to stir inside of him... also good... so she kept going. She stepped closer again, dropping her voice lower as she said "I'll have you know, nothing you could ever do is going to hurt me, Tinker. My bones can't be broken, I'm as stretchy as a changeling, I can survive the vacuum of space without needing to breathe..."

Shuddering, Tinker clenched his hands... he was growing very, very tempted. Tempted to grab onto Luna by whatever part of her he could get his hands on, and ram his cock into her as roughly as he could until he was finally able to cum. It was like his dragon half was catching on to something he was missing, and he found himself unable to look away from Luna... or perhaps... his prey?

She could feel it, the magic, and now Tinker must be feeling it too! That rush of magic deep within him, dragon magic, she could see it on his face, the flickers of hunger before he began to look worried.... Luna knew he would be having second thoughts, denying the instincts that she was poking and prodding, so she tried to make it even more alluring. She slowly licked the side of his cock, then she rubbed her snout against it with a wide smirk. "What are you going to do, summon your dragon magic?" she asked, as she cupped his balls with one hoof, fondling them and feeling the weight and the tension in his sack.

"L-Luna, I... I think my greed is..." Tinker said, his cheeks starting to turn red as he looked even more worried. Luna seemed to be ignoring his warnings though, because she sat down between his hind legs, placing both of her hooves on his cock. Then, she began to stroke it, making his cock fire off a splurt of precum as he groaned with pent up pleasure and weakly humped into her stroking.

"Yes! Good! Embrace it! Teach me a lesson, Tinker! Show me what dragon magic is like!" Luna squeaked, stroking his cock even faster with both of her hooves, looking up at him with a big, wild grin on her face. "I'm yours, if you only-".

As she spoke, Tinker gasped, and he shuddered in place as the magic finally took hold, warmth and power spreading through his body. Luna watched with held breath as Tinker suddenly grew, his cock flexing and bulging in size as he gained an inch or two in height. With the tinkling sounds of shattering magic, the spell holding back his orgasm broke, and Tinker gasped as he felt his cock suddenly buck, his orgasm taking him by surprise as it was suddenly let loose.

He growled at Luna, and she felt her pussy wink hard as Tinker lunged for her. With one hand, Tinker grabbed the mare's horn, and he pulled her close to his cock just in time for his first gush of cum to splatter her in the face, making her yelp and blush hotly as she weakly pulled away, but... she was helpless now.

Dragons were magical creatures, and if a dragon was gripping the horn of a unicorn or an alicorn, they were rendered powerless. Luna nearly came on the spot as Tinker shoved her down onto his cock, plugging her throat with his ridged shaft just in time for a gush of his cum to paint her throat white. She loudly moaned around his cock, then she squeaked as he shoved her down even further, stuffing his knot past her lips. Luna squirmed, her hooves unable to find purchase underneath her, and as Tinker mashed her nose into his crotch and placed his other hand on her head to hold her down, she came.

Tinker didn't even notice at first, too overwhelmed by the powerful waves of orgasmic pleasure he was feeling as he finally began to pump his cum inside of Luna. His hips gently humped against her snout as he held her down on his cock, and he couldn't help but shudder as he realized that Luna was also cumming. Midway through his orgasm he shuddered as he felt another rush of tingles from his magic, and he looked down at his body just in time to see himself grow slightly larger in size again. He probably stood taller than Luna now...

As Tinker's cock pumped thick, hot gushes of cum into her guts, Luna's mind was a whirlwind of arousal and pleasure as she quivered in his grasp. Perhaps her acting had been cringey, but finally, she'd done it. Tinker's greed magic had woken up, and he'd finally shown enough initiative to take control, grab her, and use her.

Of course, Luna didn't want to be degraded and treated harshly, but she did want to be taken advantage of by a bigger, stronger dragon, and if Celestia trusted this stallion enough to take her to bed, then Luna trusted him too. By this point, she didn't have a choice, and that only fed into her fetishes even more. Tinker kept her held down even during his post-orgasm afterglow, though during it, he met her eyes and flashed her a smirk, watching as the blue mare quivered and whimpered in response.

Slowly, Tinker pulled Luna off of his cock, watching as she sucked in a breath, trying to drink in the scent of his musk before she was pulled away from his cock. He kept one hand on her horn as he said "Is it true, Princess, that a dragon can cut a pony off from their magic merely by holding their horn...~?"

It took Luna a moment to find her voice, but then she squeaked "Y-Yes! Y-You've found my weakness...!" she breathed, shivering and gazing up at him with a hot red blush on her cheeks. Tinker shuddered as he felt another small surge of growth, and with it, a surge of confidence. His cock was already drooling precum again, and he brought Luna's snout to it as he lit up his horns with magic. He cast a spell, he shuddered a little as his cock twitched, and Luna gazed at it with excitement as she whispered "W-What did you..."

"If I'm going to breed the vulnerable little pony princess I've just captured, then I want to make sure I'm filling her with nothing but pure cum, don't I...~?" he growled teasingly, making Luna close her eyes and force a hoof between her hind legs as she splattered it with her arousal, not cumming, but close. When she opened them, she realized that cum was flowing from his cock, having replaced his precum.

"I-I'm yours, Dragon..." she breathed, making Tinker shiver as he went through another growth spurt, his cock firing a gush of cum all over Luna's chest. With a grunt, Tinker stood up, then he stood Luna up. Once she was on all fours, Tinker mounted her, making the princess shiver with lust as she felt his body settle atop hers. He pushed her head down, and Luna allowed her front legs to collapse, bringing her chest to the pillows as she spread her hind legs open. Tinker settled in place atop her, and he buried the tip of his cock just inside of her folds, making her whine and clamp down tightly around his cock as he pumped a gush of cum into her pussy. "Please!" She cried out, squirming helplessly beneath him.

Tinker's breath caught in his throat, and his cock bucked inside of Luna as he leaned closer, whispering "I-It turns me on when you struggle~". Before Luna could react, Tinker bucked forwards with a strong thrust of his hips, and Luna cried out as his cock plunged deep inside of her, plugging even her womb as he stuffed the knot and all inside of her. Now that he was hilted, he shuddered as he felt his body grow a bit larger again, and Luna bit her lip and closed her eyes tightly.

Dangerous. She was in a highly dangerous position, and she'd managed to keep it hidden. An orgasm fueled by dragon greed was strong enough to blast through almost every contraceptive spell that there was, and Luna was taking a huge risk tempting the brown dragon to flood her with cum while under the effects of dragon greed. And yet, as Tinker pulled back to start thrusting into her, the only noise Luna could make was a squeaky cry of delight as she rocked back against his first thrusts.

Tinker started off slow, but he began to notice something as he rocked his hips against Luna. His greed was starting to work along with him... every time he thrusted into Luna, he felt another tiny surge of growth. The sensations were incredible, and he didn't dare stop, but some small part of him worried about how large he would be getting.

He ignored it. Instead, as Tinker bucked into Luna, he let his free hand roam her body, though it was hard to focus on it with how good it felt bucking into her. He felt up her flanks, her chest, he ran his hand through her mane... it was hot, holding her down and fucking her like he was. While Tinker was thrusting into Luna, the mare slipped a little, and she squeaked as she found herself sliding forwards, away from Tinker. Without missing a beat, the dragon followed, and his cock only slid out of her partway before he rammed it right back inside.

Luna shuddered with excited bliss, crying out a weak "Y-yes~!" as she squeezed his cock tight. Just the simple action of following her when she slipped, keeping his cock inside without missing a beat, it really highlighted the inescapable rutting fantasy that Luna was wallowing in.

As if punishing her for trying to escape, Tinker softly bit down on Luna's neck a little, making her squeak as he pressed close, exchanging his deeper, slower thrusts for short, quick bucks into her, changing up the rhythm again to to the tune of happy squeaks from Luna... but Tinker wanted something different.

He thrusted deep inside, knotting the mare on his cock, then Tinker wrapped his arm around Luna and rolled over, laying back on the pillows. Luna let out a cute squeak, but she couldn't do anything about it as Tinker got comfortable on the pillows. Then, Tinker let go of his horn, and he slid both hands down to Luna's hips.

Grabbing her flanks, Tinker pulled Luna off of his cock, spun her around, then he sat her back down on top of it, watching her shiver and moan as his length plunged back into her. He watched with a hot blush as his cock produced a bulge in the mare's body, and as he buried his knot inside of her, stuffing part of his shaft into her womb, he could see the tip of his cock and a few of his ridges making up the bulge in her belly.

"What's wrong, princess?" He asked, smirking up at her. Now it was his turn for the cheesy teasing, as he let go of her hips. "I've let go of your horn, so you're free to go now... all you have to do is pull off of my cock, surely a dragon's knot isn't enough to keep a princess trapped, is it? Or is the princess of the night enjoying what it feels like letting a dragon have his way with her...?" Tinker growled softly, before shivering as he grew a little bit larger, sinking his cock a bit deeper into the mare.

Luna shuddered on Tinker's lap as she clamped down as tight as she could around him, her cheeks burning a hot red as her wings twitched behind her. She was a mess, more aroused than she could ever remember being. Whether he meant to or not, Tinker was hitting all of the boxes, and Luna was struggling not to cum again as she gazed up at him. By now, he would stand taller than Celestia, and she could feel the pointed tip of his cock gently nudging against the far wall of her womb.

"I-I'm going to... t-to... I can't help it, you're going to make me cum again!" Luna gasped, struggling to get her words out when Tinker bucked his cock into her while she was trying to talk.

"Go ahead and cum, it'll just make it easier to breed you~" Tinker growled, as he slid his hands in front of Luna, grabbing both of her teats and giving her nipples a firm rub with both thumbs. Not realizing that he was playing right into her growing desire for an egg, Luna cried out as if on command as she came, her pussy massaging Tinker's cock with repeated clenching and squeezing as the pleasure filled her head with a wonderful fog of bliss.

As Luna rode out her climax, Tinker simply enjoyed the sensations. It felt amazing having her pussy milking and squeezing him with such desperation, and he began to grope her teats as he watched her cum, admiring the expressions she made and the way her body quivered and shook as she orgasmed.

It occurred to him that Luna was being quite vulnerable with him, because in real life, she was the hardened of the two sisters, and yet here, in this dungeon of hers, she was letting Tinker have control, have her to do with as he wished. It was... hot, and flattering, and oddly enough, it made him happy knowing she trusted him so much.

Of course, perhaps she just thought she owed him, considering the mindblowing nightmare moon breeding session he had been treated to in his dreams. He would have to offer his mare body up to Luna sometime to see if she would try it again, for real, just... maybe not breeding this time.

By the time Luna's orgasm was over, Tinker had grown even larger. As he ground into her, another ridge popped into her womb, but tinker couldn't see them anymore. With all of the cum that he was pumping into her, Luna's belly had begun to expand, which was both good and bad all at once. Good, because it gave his cock somewhere to go as it sank deeper and deeper into her, but also bad, because... well... actually, it was pretty hot all around.

And it wasn't the only part of her moving, either. Every time Tinker shoved Luna down into his lap, stuffing his cock inside of her, the mare's teats would gently plap against his crotch, jiggling appealingly. Not only that, her hips would smoosh against his own, soft and warm, making for plenty of cushion between the two of them.

It was a pretty hot view, all things considered, and Tinker's eyes hungrily roamed the princess as he forced her to ride his cock, even though she was barely doing much of any riding at all. Her belly jiggled a little as Tinker let her drop into his lap one more time, sliding his paws up and down her body to feel all of her curves again. When he was done, he slid his paws back to her hips, grabbing onto them tightly. He could feel his greed magic gathering in his arms, as if it knew what he planned to do. He grinned, meeting Luna's gaze, and he pulled her off of his knot as he said "Final stretch, Princess~".

Luna let out a groan of bliss as Tinker pushed her back down onto his cock, her hind legs refusing to listen to her commands as she tried to help him along. "I-If you... don't cum inside of me... I'm locking you up down here... as my personal sex toy... for a year" Luna hissed, glaring down at Tinker for a few moments at the peak of one of his thrusts. Tinker shivered a little bit, and he nervously nodded back at her in agreement. Of all the threats he'd been given by the sisters, this one seemed very real.

Of course, he fully intended to cum inside of the princess. To do anything else was insane! "N-Nothing is going to stop me from knotting you, holding you there, and pumping every last drop straight into your womb..." Tinker hissed faintly, his cock twitching firmly inside of Luna as he shoved her down onto his cock a little stronger than normal. Oddly enough, despite how he was doing all of the work, Tinker's arms weren't tired at all.

He blamed it on his greed, really. With every thrust he made, shoving Luna down onto his cock, Tinker grew just a little bit bigger. The longer it went on, the more Tinker began to feel like a big, hulking dragon taking advantage of a cute little pony princess, and the hotter that idea felt to him. The faster that he shoved Luna down onto his cock, the more her teats and her hips would jiggle against him, making for lewd plapping noises as he fucked the attractive princess.

Not only that, but her belly was growing increasingly bigger, and he could almost hear his cum sloshing inside of her with every thrust. Luna could certainly feel it, and according to her, it was just as hot as it seemed like it would be.

However, the bigger Tinker grew, the more sensitive he became. The more he stretched out Luna with his cock, the tighter she got around him. Luna could tell he was getting close when Tinker's ridges began to harden, and she squirmed as she squeaked "H-Harder! Please! N-Now that you're close!"

Tinker hesitated for a moment, but... everything was building up to this, so he went with it. Digging his claws into Luna's flanks, Tinker spread his hind legs open a bit more, and he grunted as he set to work fucking his princess. Already on the brink, Tinker didn't need much encouragement to hit his climax. He rammed his cock into Luna, pulled her right back off of it, giving her no time to catch her breath or get used to it.

This time, Tinker brought his hips into the mix. When he shoved Luna down into his lap, he bucked up with his hips, ramming his knot into her even harder than before. When he pulled her up, he pulled his hips away, dragging his ridges out of her faster so he could ram them back inside even sooner. The room filled with her loud cries of pleasure and a messy, wet, plap-plap-plap-plap for about a minute before Tinker was forced to give in. He loudly groaned a he arched his back, aiming his cock for Luna's womb as he rammed her down onto it, and then he held her there as his cock began to bulge with his cum.

As Tinker hilted, his greed sent one final shockwave of growth through the dragon, making him grow bigger one last time as his cock swelled inside of Luna. With his final spurt of growth, Tinker's knot filled Luna's entire pussy. His thick knot was now large enough that her entire marehood was needed to contain it. Any further back, and his knot would pop out of her. Any further forwards, and it would pop into her womb.

Speaking of her womb, the rest of Tinker's cock was now buried in the mare's vulnerable womb, all of his ridges having slid through her cervix to make it inside. The tip of his cock was deep enough in her belly to actually reach through all of that cum and touch the other side... but then a tsunami of his thick dragon cream flooded her womb.

After all, he was cumming. Tinker's cock bulged inside of the princess, growing even thicker as a stream of his hot seed was routed through his knot, and down his length. As the cum passed through Luna's cervix, Tinker's dragon greed smashed through every single anti-pregnancy ward that Luna had, and she screamed as she was suddenly overwhelmed by the sensations of the soft wall of her womb being blasted with a jet of thick, hot dragon cum.

By the time his second strong gush of cum was fired into the mare, Tinker collapsed back onto the pillows, and his tail wrapped around Luna's body, right between her legs and her growing belly. His claws dug into her hips to keep her lodged on his cock, and he began to bloat her womb with his seed even further than it already was. Her belly sloshed with cum as his cock fired gush after gush of the virile fluid inside of her, and Tinker even flared his wings open to either side as he settled in to his climax.

Luna's orgasm, however, wasn't exactly something she could settle into. The blue mare had many more wards than her sister, and she was overwhelmed by the intensity of having her completely defenseless womb violated by the thick, hot seed of a dragon, breeding her as she helplessly orgasmed all over the cock that was claiming her womb.

Whether it was her body milking him, his greed magic boosting his sack, or some other thing, Tinker had gallons and gallons of cum to pump into Luna. She couldn't even catch a rest as he came, because his cock was constantly flexing and bulging and twitching inside of her, and the cum in her belly was swirling and gurgling and making her jiggle as he pumped more and more and more inside of her.

Luna almost passed out, but her orgasm almost went further than that. Rather than threatening to pass her out, the pleasure gripped her, forcing her to endure every last moment of the bliss and ecstacy coursing through her nervous system. She was hyper-aware of everything; the cock gushing inside of her, the claws holding her down into his lap, the tail gripping her, her teats being smooshed by her gradually swelling cum belly, all of it. She especially liked the slight pain from his claws digging into her flanks, because it was an arousing reminder that she had no chance to overpower the strength of the larger dragon and escape his cock, as if she would ever want to anyway.

But to her, right now, not having the option was much hotter than having it and simply choosing not to take it. One was simply her deciding to let a dragon breed her... but the other was a dragon overpowering her and claiming her womb with his eggs, and that was hot.

The blue mare's orgasm almost lasted as long as Tinker's, but she failed to keep going as long as he did. Not that she cared, because her afterglow was perfected by the sensations of Tinker's final streams of cum gurgling into her overfilled womb. By the time his balls ran dry, Luna's womb carried gallons of hot dragon spunk. In fact, her belly was resting on top of his, and Tinker couldn't even see her teats anymore past her cum belly.

A faint shimmering caught the attention of both ponies, and they both turned their gaze to Luna's belly as Tinker's cutie mark shimmered into view. Taking the dragon by surprise, he blushed as his cock fired off a final jet of cum into Luna. As the mare's suspicions were confirmed, however, she reacted even more strongly, digging her hooves into her belly and quivering atop Tinker as she whispered a shaky, faint "Yeeeeessssss.....~!"

With as intense as their shared climax had been, both ponies would take quite a while to melt into their afterglow, and even longer to be able to think straight. Not like they minded, as neither of them wanted to budge. Luna didn't want to give up the thick dragon meat that was keeping her plugged, and Tinker didn't want to give up the tight marehood that was keeping his cock warm.

"Tinker, it's not gonna..." Luna said, scrunching her snout as the dragon carefully lowered her to the floor... and set her down. Luna did her best to reach the floor with her hind legs, but as her weight came to rest on top of her cum belly, her legs were pushed out from underneath her, leaving her helpless on top of the big, warm, built in waterbed that she now had. Cumbed?

"Okay, okay, lemme help ya..." Tinker said, scooping the mare back up in his arms again. "But really, how long am I going to be this big?

"Well... I wanna show you off to a few of my most trusted batpony guards..." Luna said with a suspiciously innocent smile. She reached up to nuzzle Tinker's neck, dropping to a lustful voice as she growled "I want them to see the beastly dragon who finally claimed my womb after so many centuries~..." in a soft, almost-whispery voice.

Tinker's cheeks burned a hot red as he carefully laid the mare on her back on some of the pillows, saying, "W-Well, I suppose I don't exactly mind that too much..."

From her position in the pile of pillows, Luna smiled up at Tinker. "Seriously, though... this has been the best rut I've had since getting back from the moon, and I've been trying to catch up on what I missed~" she hummed, giggling a little bit. "It's only a matter of time until I get my hooves on a real dragon who ticks off all of my boxes... not even you fit all of them, but you hit all of the important ones" she said.

"What's one that I'm missing...?" Tinker curiously asked, his head tilting just a little bit as one of his ears flopped down.

Luna giggled, then she said, "Well, if a dragon was to tick all of my boxes, their scales would be an inky black color, darker than the night sky, so you could only see them by looking at where the stars were going out..."

Tinker nodded along, picturing it in his head as he said "Well that sounds pretty cool, yeah..."

Then Luna smiled, saying, "Ooh, and you know what would be cool? Imagine a dragon with... purple glowing eyes..."

"I dunno, that sounds pretty familiar..." Tinker said, rubbing his snout a little bit with one hand.
