It was a hot summer afternoon and Spike sat in a shadowed alcove near the center of the Canterlot hedge maze, far from any listening ears and out of sight even from any pegasi that might fly overhead. Sweat glistened on his scales. His mouth hung open in a pant as he vigorously stroked one hand over his pink, glistening-with-pre cock. He moaned as he fapped, hand a blur on the six-inch shaft, fingers tightening every few seconds to tease the pointed head, scooping up the pre bubbling from it and smearing over the rest.
“Ohhhh damn did I need this… two d-days of helping the princesses non-stop… gotta get in all I can….” He’d been going at it since early that morning, the one free day of his trip to Canterlot. Already his body showed the fruits of his work. His belly, chest, thighs, and even his face were positively painted white in creamy dragon cum. Dragon stamina was a thing of legend, and rightly so.
“Nnnngh… yes, yes, yesssss….” Spreading his legs wider, Spike curled his tail over and slid the tip into his tight, squeezing anus. A shudder ran through his body as he tail-fucked himself in time with his masturbating, his moans growing louder, needier. “Yes, yes! Aaahhhh!” His hand sped up and his asshole tightened. Pre shot out in spurts, splattering his belly as a fire kindled within him. The inner fire grew, spreading to every inch of his body, aching, burning—
Suddenly, release. Spike threw his head back and roared, eyes clenched shut and green flames flickering at the edges of his mouth. All the while his cock twitched and throbbed, giving his belly a fresh coat of cum.
A minute of mindless bliss as Spike basked in his pleasure, slowly pulling his tail from his anus so that the smooth nubs rubbed across his inner walls in just the right way to send a few more spurts of seed from his cock. A low moan left him as he relaxed, leaning his back against the hedge wall behind him. “Oh man, that was the best yet… and there’s still all day left, hehehe.”
“Well well, what do we have here?”
Spike froze just as he’d been reaching toward his still-hard cock to masturbate once more, fear and embarrassment filling him at the sound of the posh stallion voice from just around a corner in the hedge. Before Spike could do so much as tuck his shaft back into its slit between his legs a blue-toned magic took hold of his body, pinning him where he sat and holding his limbs straight out to the sides. The position left his shaft and asshole totally exposed to any onlookers.
Prince Blueblood came out from around the bend in the hedge, a slap-worthy smirk on his face and, to Spike’s shock and reluctant admiration, a beast of a raging erection between his legs. “Well then, if it isn’t the assistant to that Princess Twilight Sparkle. My dear Auntie’s favorite student.” The unicorn stepped closer, his horn glowing with magic, his smirk growing. “What was your name again? Stakes? Snarl? Some uncouth dragon name, I’m sure.”
Spike’s cum-stained lips drew down in a growl, muscles straining as he struggled within Blueblood’s magic grasp. “It’s Spike, you jerk! Now let me go right now!”
A low chuckle as Blueblood stopped a foot from Spike, levitating the baby dragon into a kneeling position facing toward him. “Now, why would I want to do a thing like that? Perhaps you didn’t know, but I happen to… crave, uncouth dragons such as yourself. A deplorable weakness of mine, really, but one I won’t fail to indulge in when I get the chance. Like now, for instance….”
Spike gulped then, suddenly having an idea what Blueblood wanted. His eyes, unbidden, went to the cock between the unicorn’s legs. It looked even bigger, close as Spike was. As long as one of the prince’s legs, at least, and several inches round with the same broad, flat head he’d seen on any other stallion. Spike gulped again. “Y-you don’t really w-want me to—”
“I do!” Blueblood dropped his front hooves to Spike’s sides, the fat shaft slapping against Spike’s face and leaving a splatter of pre. The musk of a fully-grown, aroused and dominating stallion sent Spike’s mind reeling. “Do it, or else I’ll tell my Aunty and your dear Twilight how naughty a dragon you really are. But do it well, and maybe I’ll give you a nice reward. Prince’s honor.”
That threat was enough to get Spike moving. With only a second more of hesitation, the baby dragon opened his mouth, slid his reptilian tongue out, and began to lick the prince’s shaft. The taste was… oddly normal. Sweaty, which was a given, but otherwise, but otherwise like just plain, bare skin. It wasn’t bad, actually, was kinda growing on him.
“Mmm....”
Spike stuck out more of his thin tongue, wrapping it over the meaty length and swirling, caressing every inch, squeezing, listening with some satisfaction to the pleasured groans and whinnies of the stallion above him.
“By Ce-Celestia… hnn… you’ve d-done this before, haven’t you?”
Spike shook his head, unwilling now to break contact with the cock even if he got the chance. He wrapped it up in his tongue, sliding the makeshift sheath up and down the length at a tantalizingly slow pace. With a few free inches left over at the tip of his tongue he licked over Blueblood’s fat, sweaty balls, plump with the stallion’s seed. Spike slathered the softball-sized orbs with saliva, shivering and moaning at the overpowering musk coming from them. His own cock throbbed beneath him, dribbling pre, ready to pop without a touch from Spike.
Reaching Blueblood’s balls with his tongue incidentally pushed the head of the unicorn’s dick against Spike’s mouth. Without thought or hesitation he wrapped his lips around the broad head, suckling on it like he would a fat teat. The pre spurting from the urethral slit had little taste, maybe slightly sweet, yet Spike eagerly gulped it down anyway, panting, suckling harder. “More,” the young dragon thought.
“Nnngh!” Blueblood lurched forward, one fore hoof going to the back of Spike’s head to keep him place as the unicorn began thrusting hard and fast into his mouth, snorting and bellowing like a stallion in rut. Unable to concentrate Spike drew his tongue back into his mouth, focusing his efforts on sucking on the fat shaft starting to ram its way down his throat.
“Nnngh, hold still you filthy animal! Re… receive your prince’s royal load!”
Spike gagged on the cock pushing deeper and deeper down his throat, tears coming to his eyes and hands moving to hold Blueblood’s thighs as he struggled to breathe. Still he sucked, tongue dragging over the meat in his mouth, silently begging for that royal load.
With a final whinny, Prince Blueblood delivered. Spike groaned as the cock thickened in his mouth, his throat bulging as each spurt of thick, creamy cum traveled the length of Blueblood’s cock and shot directly into Spike’s stomach. Almost immediately the baby dragon felt his stomach fill up with cum, his belly swelling rounder and rounder as it was filled to capacity, and then beyond.
“Hhhnng… hrrrk….”
Spike’s rear legs kicked against the ground, his tail flailing and claws scrabbling for purchase as his belly kept growing, inflating with stallion cum until he began to look less like a dragon and more like a balloon.
“M-much longer,” Spike thought, vision getting hazy, “And I’m going to p-pop….”
Finally, after a near minute of continuous orgasm, Prince Blueblood let go of Spike and fell away with a groan onto his back, cock pulling free and falling limp against his belly. “Sweet, merciful Aunty… I’ve never cum like that before… some, some magic involved, maybe… Spike?”
Spike lay bloated on the ground, his stomach swollen so much he looked like he’d swallowed a whole watermelon in one bite, eyes glazed over and some cum leaking out from between his clenched-tight lips. His hands absently caressed the bloated mass that was his belly. His cock stood up straight, hard and throbbing. His thoughts were scattered and strange, growing primal as he basked in the carnal atmosphere. He felt the unicorn’s cum inside him, filling his every inch with warmth and lust. The baby dragon wanted, NEEDED, to return that favor.
Blueblood let out an uneasy laugh as he approached the little dragon, his limp cock growing hard again despite himself. “Uh, Spike, darling? Are you okay? Do, do you need me to summon a doctor? Or, or… maybe I should give you that reward for a job well done later—”
“NO!” The little dragon suddenly lurched up onto all fours, Blueblood letting out a shrill yell as thoughtless draconic eyes focused in on him. “Spike want reward NOW!”
Blueblood’s jaw dropped as the dragon grew before him, that cum-swollen belly disappearing as the rest of his body grew to match, grew until he barely fit between the hedge walls and he had to stoop to keep from being seen. But what Blueblood couldn’t stop ogling was Spike’s spear-like cock, red and throbbing and nearly as long as Blueblood’s body, hanging low beneath Spike from its own weight.
“SPIKE WANT PONY ASS!”
Blueblood screamed like a filly and turned to run. The ground shook beneath his hooves and suddenly a pair of clawed hands grabbed hold of him by his soft few-too-many-cakes flanks. Another scream left him as he was lifted up into the air, eyes widening at the feel of steamy-hot breath and flecks of saliva on his royal derriere.
“MMM, BLUEBLOOD HAS SAME WHITE COAT AS RARITY….”
Blueblood squirmed, hooves kicking, a bright blush coming to his face as he felt a thick, winding tongue, warm and slick with spit, lick across and then up between his rear cheeks, providing a generous coating of all-natural lube. Desperate not to get turned into a living cocksleeve he looked back at Spike’s head a few feet from his own, trying to find some bit of intelligence in those reptilian eyes. “Listen, little, uh, big dragon. You don’t w-want me! You want that Rarity you speak of!”
Spike paused in his licking of the royal rear, blinking as he looked this stallion, only a few heads smaller than him, in the eye. “Eh?”
“Yes! That’s it!” Blueblood squirmed some more, daring to hope as the dragon set him back on the ground but kept a firm grip on his flanks. “Come on! With my help you’ll get this Rarity girl no problem!”
Spike let out a growl. “Yes… STUCK-UP STALLION PRACTICE FOR SPIKE!”
Before Blueblood could say another word the dragon loomed over him and pressed his front end to the ground. Pain unlike anything Blueblood had ever felt before hit him as the fat, spear-like tip to Spike’s cock, mercifully already lubed by the dragon’s pre-cum, pushed its way through Blueblood’s clenched virgin pucker.
“Nnnngh! O-oh Celestia!”
Inch after inch of thick, throbbing dragon-meat pushed past Blueblood’s unwilling hole, rubbing the stallion’s inner walls in ways he’d never imagined before, stretching him wider than he ever thought possible. Beneath him his own cock throbbed and spat pre, grinding against the soft grass as Spike pushed deeper and deeper
“NNNGH… SPIKE LIKE TIGHT ASS!”
Blueblood whinnied and shook, a sudden gasp leaving him as he finally felt the dragon’s groin touch his. There Spike stayed for several minutes, giving the stallion time to adjust. He felt full, more full than he’d ever felt before, like the mammoth cock reached some deep inner core of carnal lust. There was pain, but with every second that pain passed away, leaving something that wasn’t quite pleasure. Looking down beneath himself he was amazed to see his gut bulging out a good several inches, the shape of Spike’s cock clear through his skin and fur. The thought of that beast cumming inside him…
“Spike… as your p-prince, I command that you give this royal rear a royal reaming!”
Spike responded by slowly pulling out from that vice-tight rear. Blueblood moaned as the inches pulled out, blunt ridges tugging tentatively at the walls of his inner passage. Ripples of pleasure, shrouded before by the pain of the cock’s entry, shook Blueblood to his core. A leg kicked and a spurt of cum, not quite an orgasm, shot from his shaft.
Spike stopped with just the tip of his cock still inside, waited a moment, and then plunged back in to the hilt. Blueblood whinnied, eyes clenching shut as he pushed back. His body trembled with each hard and fast thrust from Spike, his gut bulging obscenely with each thrust of the dragonic tool. A lewd, wet slapping sound filled the air as Blueblood’s balls bounced about with the rocking of his body, slapping with little stings of pleasurable pain against a thigh. Moans punctuated the slapping, whinnies from Blueblood, feral snorts and grunts from Spike. Their hips blurred as they rammed into each other.
The fucking went on for what felt like hours, the mid-day sun crawling above them, the world silent beyond their wild cries of ecstasy. The friction between cock and inner wall was heavenly, hot and strange and pleasure teetering on the edge of pain. At that moment it was all that Blueblood could want or care for.
Spike leaned over Blueblood, bared teeth inches from the stallion’s face, his breath hot and heavy. “Spike like little stallion! Sp-Spike fill B-Blueblood with cum!”
Blueblood cried out at a particularly hard thrust following this proclamation. “Yesssss! Gods above, fuck me! Your p-pr-prince commands it!” He grit his teeth and clenched around Spike’s cock, squeezing the mammoth pole for all the hot seed he could almost feel churning within it.
Three more thrusts and Spike hilted himself, throwing his head back and releasing a pillar of green flame into the sky as he unloaded a flood of cum into Blueblood’s bowels. The prince screamed as he felt the steaming-hot seed gush into him, feeling for a moment like a fire hose had been turned on inside him before the pleasure washed away all that. His cock jerked beneath him and shot two, three, four loads of cum into the grass and dirt, miniscule next to the river of cum gushing through Blueblood.
“Nnngh! Nnngh, grrrrffffuuuuck! S-so much! Aaaaaugh!”
Blueblood’s hooves scrambled at the ground. His eyes rolled up into his head, his jaw slack and tongue hanging from his mouth as he learned how a mare in heat felt. Below him his belly gurgled, swelling out as the cum just came and came. Mere seconds passed and Blueblood looked pregnant with twins. Minutes rolled by and he looked like he’d swallowed another stallion whole, his belly’s skin stretching with a faint rubbery sound, wobbling as it smooshed against the ground. His legs had to spread apart around it.
“Oh gods… t-too much….” Blueblood felt the cum churning inside him. He could taste its salty sweetness in his mouth. It warmed every inch of his being.
Finally, the flow of cum slowed to a stop. Spike groaned and pulled out, Blueblood yelping as the tip popped free of his suddenly-sore rear. With the cock’s removal cum poured from the gaping hole, the effect on Blueblood’s massively swollen belly equivalent to trying to empty a bucket of water with a thimble. Blueblood groaned, relieved that was finally over, yet also looking forward to the next time.
The dragon swayed where he stood for a moment, before dropping down beside where Blueblood laid. An arm came around to hold Blueblood close, followed the next second by a deep, rumbly snore. Blueblood groaned again, resigning himself to his current fate as a horny dragon’s cumdump.
“Well… urp… at least nobody saw us….”

Princess Celestia’s hoof went to town on her quivering pussy, the castle balcony she sat on thoroughly soaked in her juices as she spied on her cousin and her good friend Spike having a go at it through a telescope. "This time," she thought, "I'll be the one sending a letter to Twilight!"

I couldn't find any fics with this pairing, so I thought, why not?
