A well-meaning wyvern does everything she can to give Andari the birthday gift she doesn't actually want. Things aren't helped by a particular drake eager to find out just how stretchy a wyvern really is.


Andari woke up nestled tightly against her mate's side. She cherished Karynth's warmth, trying to snuggle as close to him as possible and delay the start of her day.

Consciousness returned slowly as she struggled to remember why she had so much trouble getting to sleep last night. Something exciting. Her sleep fogged brain refused to cooperate. But why... oh! Her own birthday! The light green dragonesses' tail twitched.

What would her mate, Karynth, have in store for her? Karynth- or Kar as she liked to call him- planned excellent celebrations. Usually ones with lots of friends, and family too. Ugh, that family part she could do without. His in-laws were _not_her favorite dragons in the world. Still, a day with her Kar was a good day.

Her pink tongue stuck out as she yawned wide. The forest-colored dragoness tried to blink the sleep away. She wanted this day to be about her. Maybe they'd just spend all day in their nest. All day cuddling, and touching, and... Andari's tail swished unconsciously towards Kar's, the armored plates on the underside of her tail and belly curling up towards Kar's own deep red tail. Touching and... and... glurp?

Andari's ears perked and turned towards the unusual sound. Her emerald eyes blinked open to stare at Kar's crimson chest plates. They rose and fell rapidly.

Had he been out flying? She couldn't recall Karynth leaving the cave last night, but she was a heavy sleeper. A sort of slurp, glurp! filled their cave, following by a loud huff from Karynth.

Karynth lay sprawled on his back, very much awake. His eyes were closed tight, muzzle tilted back, slightly parted. His tongue drooled out to one side in obvious pleasure. He let out another huff and grunted, his front paws holding something small and beige to his crotch while his earfins twitched and quivered.

Andari mewled in shock, jerking back from Kar's side as she recognized the face buried between her mate's hind legs.

Aisu. A wyvern. Her friend. At least Andari thought they were friends. But to find the spotted brown wyvern suckling away happily at her mate's cock certainly put a hold on whatever friendship they may have had!

The green dragoness hissed, bristling with anger. Of all days! As if any day was a good day to cheat! And the audacity to do it on her birthday, right in front of her.

Her eyes narrowed into little slits, their previous emerald color rapidly dulling into a moss green. Her mind struggled to comprehend the infidelity occurring right in front of her snout.

The little wyvern could barely fit Kar's mottled pink shaft into her muzzle. Her maw opened as wide as it could go, like a hatchling's first yawn in the morning.

Andari shook her head. Aisu was no hatchling. But she almost looked like one compared to Kar.

Her whole body fit between Kar's crotch and the length of his tail. Aisu's jaw strained, struggling to fit all of his fat meat into her mouth. It easily dwarfed any wyvern phallus Andari had ever seen or heard of. Aisu's drooly tongue rubbed against the underside of his rigid shaft, encouraging him to wedge more of himself inside her maw.

Judging by the wet spot coating the underside of Kar's tail, Aisu clearly enjoyed the challenge of stuffing her mouth full of dragon cock. Every time his tail twitched upwards the brown wyvern pushed down with renewed enthusiasm. Her tongue spiraled down around his shaft, suckling to the base before pulling back, copious amounts of drool covering his cock tip like frosting on a cake.

Aisu held herself closely to Kar's crotch while Andari watched. Her winghands hugged Kar's rump while his paws pushed on the back of her head, making sure her muzzle never strayed far from his crotch.

This went on for a few moments as Andari struggled to make herself noticed. Aisu's little muzzle continued to bob up and down on Karynth's between Karynth's hind legs, causing low hisses and huffs of pleasure. How long had this been going on while she was sleeping? Why would he...?

The distressed dragoness couldn't take it. She let out an involuntary high pitched, pitiful mewl. They had to stop!

Aisu released her left winghand from holding Kar's butt and held it up to Andari in a 'just a minute' motion. Andari mewled louder and thumped her green tail against the cave floor.

It had no effect. Kar didn't even glance her direction.

Only after Aisu finished going down on Kar's cock again, swirling her tongue against his belly scales for added effect, did she pull her muzzle free. She licked her muzzle clean, stringy bands of saliva connecting Kar's twitching shaft to her chin.

"Morning Anda!" She chirped, panting for breath between her licks. A strand of drool dripped down the underside of Kar's cock tip, mixing with his dribbling pre-cum. "Just stopped by to say Happy Birthday to you!"

And with that shocking statement she plunged back down into Kar's crotch.

Aisu's reptilian slitted eyes glittered like white diamonds as she held eye contact with Andari, a grin tugging at her cheeks. Her pink tongue swirled around Kar's twitching cock, lapping the precum leaking from his tip. She made a show of enjoying the taste. Her tongue licked slowly over her lips, her throat gulping and swallowing noisily. Her black tail wagged behind her, bumping into Kar's. Kar snorted at the distraction and wrapped his tail around hers, pinning her to him.

Andari's fiery red mate, at least she thought he was still her mate, grunted in impatience. Kar didn't even flick an eye towards his own mate, his attention focused entirely on the wyvern nursing his erection.

He reached out with a paw and grabbed the back of Aisu's neck. He guided her muzzle down onto his cock, pushing firmly until Aisu started to struggle.

Aisu wing-shrugged, as if apologizing that she couldn't put on more of a show due to an impatient recipient. His shaft jabbed at the back of the little wyvern's throat. A loud _glurk_filled Andari's ears.

Andari blushed profusely at the lewd display, not sure how to react. Somehow Aisu thought she was giving her a gift? A birthday gift? What kind of birthday gift was sucking off her mate!?

And yet... no. Her tail thumped again, and again it elicited no response. And yet nothing. It was wrong and she wanted them to stop, and for Karynth to apologize, and for Aisu to leave, and- and- and she could feel the arousal emanating from between her legs. Her slit left a wet spot on the cave floor from her tail thump, just like Aisu's slit on Karynth's tail.

Andari's soft green cheeks blushed crimson. Shame and arousal mixed together as she watched.

Unable to get the two lovers to stop, and unsure if she actually wanted them to, she laid down and waited. Her emerald eyes locked onto the display, ears perked and listening to every lewd detail that emerged from the interspecies lovers.

And there were plenty of sounds originating from the two cheaters. If Andari wasn't already blushing from her unwanted arousal she'd be blushing just from the noises occurring in her cave.

Aisu slurped and schlurked with a cheerful recklessness that Karynth relished. His hips thrust upwards, wedging his erection into her throat. Any time the wyvern tried to come back up for air his paws pushed her back down, forcing her nostrils down against his belly scales while her throat bulged from his girth.

The little wyvern struggled, as if his cock had somehow grown even larger. She held her little maw open and let the impatient drake do most of the work. His pink shaft throbbed and jabbed forcefully at the back of her throat. She didn't seem to mind.

Andari could see the outline of Kar's thick shaft in the back of Aisu's throat. He used her maw like a toy. His paws grabbed at her horns as he snarled and flexed. Her throat bulged around him, suckling way too deeply.

Aisu's blinked away her watering eyes as Kar finally let her come up for a single breath. She smiled as her chest heaved for air, her lungs gulping down precious oxygen. Aisu turned and licked around her maw, looking straight at Andari.

"For you, dear!" The wyvern chirped out before returning to deep throating Andari's mate.

"W-what!" Andari squeaked. Why did Aisu keep acting like this was some sort of favor, for her, for Andari?

Andari hissed, hissed for her mate and for Aisu and for her stupid body for being stupidly aroused.

"I really don't think- " Andari started, stopping herself short. Kar leaned back against the cave wall and held up one paw to Andari's snout. His other paw went back to resting on top of Aisu's head.

"Sshh..." Karynth said, the first syllable from his muzzle this morning that _wasn't_a moan. "Almost there," he said, fondling Aisu's cheek.

Aisu's little tail squirmed with delight at the encouragement. Her tongue curled around his pink tip, stroking it while making eye contact with Kar.

Her muzzle parted in a big 'O' as she went down on him, down, down until she hilted him in her muzzle with a single motion. Andari could see her tongue swirl around his base as he gasped and spread his hind legs wider, before she repeated the whole process again and again.

Kar grunted a loud, guttural sound. His tail thrashed from side to side as his head tilted back in pleasure each time Aisu's tongue swirled around his base.

He reached down and grabbed the underside of her throat, his paws squeezing gently along the convex bulge from where his cock stretched against the wyvern's scales. He thrusted like this a few times, massaging himself through her throat as he leaned back and hissed.

"Gooood girl," he drawled. "Almost there."

Whining, Andari made a move towards the two. This had gone on long enough. Aroused or not, Karynth was her mate, Aisu was her friend, and this had gone on much longer than it should have. Andari stood on all fours, her dull green eyes returning to glittering emeralds.

Kar cracked an eye open as he noticed his mate standing. In response the red drake leaned forward. No longer leaning back, he also pushed himself forward onto all fours, all while keeping the wyvern's maw wrapped around his erection.

Aisu moved herself with his movements, all too willing to keep her muzzle suckling away while he moved around.

He stood, his nose nuzzling down at subtle crease where Aisu's tail met her rump. The wyvern stood beneath him. Her entire body fit nicely under his chest while she nursed on his cock.

Karynth turned to look at his mate. Andari stopped. Karynth smiled and raised his hind leg, purposefully giving her a perfect view.

"Like what you see?" He asked, bucking his hips slowly into the wyvern's wet maw.

"Kar...!"

"You asked for this," he said.

Andari shook her head. She kept trying to look him in the eye and kept failing, her eyes swirling back down towards his crotch.

"You did," he drawled out with a hiss. "And look how aroused you are, dear. Don't lie."

Aisu's tail wagged, pleased with herself for causing the interruption.

"I did- " not, she was about to say, but the 'not' caught in her throat.

Andari suddenly remembered. A month or so ago she and Kar had been lying together in bed having a pleasant pillow talk. Teasing. Joking. She didn't mean... but apparently he had taken it seriously. Andari's green cheeks flushed red. She curled her tail around herself tightly, trying to hide her arousal.

"Of course you did... Happy Birthday, sweetheart!" And with that he was done talking with her. He turned his head away but kept a hind leg up for her to watch.

It wasn't serious! She told herself, over and over. But Kar had taken her seriously. She hadn't meant for him to actually do anything, with anyone. It had just been talk.

It had just been arousing, titillating talk. The thing you joke about in your nest with your slit already filled with your mate's cum.

Reality proved to be something different. The initial arousal from any sexual act started to fade, replaced by a sense of dread.

She had made a terrible mistake, and this was her fault. She had told Kar she wanted this, or well maybe not exactly this, but something very much like it. And he had made it happen. And now they thought they were doing her a favor.

Andari whined and curled up in a circle on the ground to watch. All her fault. And if she stopped them... who knew what would happen? Would they even forgive her?

She chewed on her tail tip, watching Kar's pink cock move in and out of Aisu's muzzle. His thrusts grew shaky; he had to throw a wing out for balance to keep himself from falling on top of the wyvern.

If she stopped them? She realized even if she wanted to, she was powerless. She couldn't stop Kar no more than she could stop the sun from rising. Kar was going to- going to- Andari whined loudly.

Aisu gave her the equivalent of a wyvern thumbs-up with her wing hand and kept sucking. Kar was going to cum and fill her friend's gullet with semen, and there was nothing she could do.

As if on cue Kar shuddered, his eyes going half lidded in pleasure. His hips puuushed forward as he tried to shove every last inch of himself into Aisu.

The light brown wyvern gurgled and exhaled loudly through her nostrils. Her tail lashed back and forth, tapping up against Kar's front legs.

Kar roared when he finally came, his cock swelling and spurting large squelches of cum directly down into the wyvern's throat.

She swallowed as best she could, not that it was necessary; Andari could see each throb of Kar's cock shooting directly into her gullet by the way her throat expanded around his engorged shaft. She could almost see all that semen pooling down into the little wyvern's belly.

Every flex in Aisu's throat was accompanied by a tail twitch by the great red drake. His tail flagged with each spurt, accompanied by a deep grunt.

Aisu for her part kept silent, busy enough with swallowing and dealing with over productive dragon seed meant for a dragoness, not for a small wyvern. But she swallowed it all without missing a drop.

Eventually Karynth's tail flagging slowed. He kept himself buried in the wyvern's maw for much longer than that though, drawing it out, rubbing himself through her throat as she purred up at him.

Andari's heart pounded loudly within her chest. She couldn't hear anything but the blood rushing up to her face and ears. She was sure that she looked like a tomato as she thought about what would happen next.

Aisu would leave, and Andari would explain to Karynth in private that it didn't turn out like she wanted, and it would never happen again. Yes, it would be okay, she told herself.

Karynth's cock eventually softened, slurping out of Aisu's muzzle noisily as a splat of semen fell to the ground.

Aisu apologized, giggling and licking dragon cum off of her snout. The wyvern turned and said something. Andari tilted her head, the sound of her heart pounding drowning out anything else.

"What?" Andari asked, trying to focus. She stayed curled up on the ground, unmoving.

Aisu chirped a little louder. "I said, how was that, Anda?" The wyvern smiled, a splotch of pearly cum still on her cheek where her pink tongue couldn't quite reach.

"Oh... I, yes, it was." Andari just made up words at this point. Silently she prayed, just please go away without getting angry at me.

"It was what?" The confused wyvern asked. She stood up on her wing-paws, head tilting curiously to one side.

Karynth ignored the conversation, instead choosing to lie on his side and close his eyes, his tail wrapped protectively around Aisu.

"It was, uhm, for my birthday," she mumbled. "Thank you," she added, hoping that would be the end of it. It wasn't.

"Oh Andari," Aisu said, sitting back on her haunches. "Was it not enough? I tried to make it a good show for you."

"That isn't- "

"You know," Aisu talked over her, her voice sounding thoughtful. "I wasn't _really_planning on going further than oral, but if that wasn't enough... and it is your birthday... well, okay." Aisu nodded to herself as she came to her decision. "That settles it. As long as Kar is up for going a bit further, I am too. Just this once," she said with a big wink.

Kar's earfins perked up. He rumbled deep within his chest. His tail coiled inwards, pulling her body close to his.

"I'll take that as a yes," the little wyvern giggled.

"Wait, no, you don't- "

"Oh really Andari, it's fine." Aisu untangled herself from Karynth's tail and arranged herself on her back, stretching out her limbs as Karynth stood back up. "Anything for your birthday, dear."

Karynth stood up and climbed over her. Each of his front paws was the size of Aisu's whole face. He rumbled and purred down at her, clearly pleased at the sudden turn of events.

Andari was clearly not pleased at the sudden turn of events. She peeked her head around to try and talk some sense into both of them.

"I really don't think- "

"Oh, but I do think," Karynth smiled and growled playfully.

Would no one even let her finish a sentence? "But- "

Karynth reached out with his paw to fondle Andari's muzzle. "Hush, just lie back down. There you go. Enjoy it... I know you do. Happy Birthday, dear."

Andari mewled and laid herself down as instructed. She sat her muzzle on the cave floor and watched her mate straddle another female.

He lowered his haunches to rub his hips down against the wyvern's most private scales. His cock bulged within his genital slit, eager for another round- eager for a proper breeding.

Aisu looked up to Karynth and back down to Andari with a hint of worry on her muzzle, which looked rather comical from Aisu's upside down position.

Andari's involuntary grin at her peculiar face apparently transmitted reassurance; Aisu smiled back and stuck her tongue out at Andari. Her muzzle still had the scent of cum on it. Aisu wriggled her hips up against Karynth, pressing herself firmly against his crotch. Her vaginal slit parted slightly against his bulge, smearing him with her arousal.

"Happy Birthday, Andari," she said with a smile, before looking back up at Karynth.

Karynth rumbled his agreement. His erection stood hard at mast again in record time, smearing cum against the soft scales between her legs. Pressed up against Aisu's tan slit, the length of his cock reaching the wyvern's middle.

"That won't even fit!" Andari blurted out, grasping at straws to make it stop.

Karynth leaned down, tongue licking affectionately over Aisu's tan-spotted muzzle. His wet tongue curled around her jaw, covering her with licks.

"Of course it will, she just needs to relax. Mmmn," he said, nuzzling and kissing against her neck. He worked his way up with kisses until he could nibble on her eyeridges.

Aisu giggled, her hind paws twitching in the air. "Good little Aisu, right... there," he said as he shifted his hips, wedging just his tip inside her tight slit.

Aisu's tilted her head back and moaned. Even just Kar's tip looked much too large for the wyvern. The tiny cleft of her sex spread obscenely around his shaft. Surely they could go no farther than that, thought Andari.

Wrong. So, so wrong.

Karynth gripped Aisu's neck firmly in his jaws and thrusted with his hips. Each motion rocked the wyvern's whole body backwards. Andari watched her friend's slit widen slowly to accommodate her mate's girth.

Andari squirmed with memories. That should be her slit around her mate's penis. Her slit getting stretched and bred and filled. But it wasn't. She could only watch and leak arousal onto the ground that she shamefully tried to hide.

The wyvern's tiny sex bulged and stretched obscenely as Karynth's cock filled her. Andari could see every inch being stuffed into Aisu: the subtle outline of his cock pushing up from inside her slit, moving with every thrust, pushing deeper each time. Each second she thought no, surely no more; and every second Aisu and Karynth panted together, their bodies rocking back and forth as Karynth wedged more of himself inside of her.

The two cheaters paid her no mind. They acted like they had forgotten that she was there entirely. And maybe they did.

Andari watched with dull eyes as both of their muzzles parted in little O's, mimicking one another. Both tongues hung out to one side, both grunting and hissing like they were made for each other, even though they so clearly weren't.

They were different species, and the differences showed as Karynth struggled to bury all of his mottled cock into the squirming wyvern.

She squeaked and hissed as he pounded against her rump. Every time he got to his base he pushed, grinding against her, legs kicking as he tried to breed her fully. Roaring in frustration Karynth reached back to grab her rump with a paw, holding her up at a better angle for himself; and coincidentally, a better angle for Andari to see the action.

The angle worked. Karynth hilted himself as Aisu's squeal turned into a high pitched rawr. The red drake ground his hips against her, their two draconic slits meeting with a wet glurp!

"Okay! That was quite the birthday," Andari squeaked, unable to watch. "You can stop now!" Neither of them heard her.

Karynth pulled back an inch, only to slam himself back into his wyvern lover with a slap. Aisu's toes curled. Again and again he did this, never pulling out more than a few inches of his mottled cock from the warm, silky grip of the wyvern's sex.

"That- that is- " Andari mewled softly, to no one at particular. One dark green paw reached down between her legs as she imagined herself in Aisu's position. She watched her friend's slit stretch in an obscenely wide oval around her mate's shaft. She could see how tightly Aisu gripped him, their size difference providing an obvious source of pleasure for her mate. It looked so hot, both of them mating, breeding in front of her... Andari's paw came back drenching wet. She set it down hurriedly before anyone noticed.

Karynth pulled back, further this time. Maybe he had heard her. He pulled back until just his tip was left twitching inside that light brown scaled slit. His paw groped and fondled at the wyvern's rump and tailbase. He squeezed around her little tail, massaging it, never letting her rump touch the ground. Then the drake pushed forward slowly, deliberately so, letting out a loud groan as he did so.

He looked so... so... happy. Both of them did. Andari blushed, feeling like an intruder to their pleasure.

Karynth hilted himself again inside the little wyvern and resumed his thrusting. He thrusted like an animal. Rapid and wild now that he could stuff himself fully into her. His instincts took over; Andari watched as her mate devolved into a horny feral trying to seed a dragoness and give her a swollen belly.

Aisu responded in kind. Her meek mewls and hisses turned into snarls and nips. Her wing-arms lifted to wrap around Karynth, hugging herself to him.

Andari could no longer see their faces- she could only see a red drake's rump pushing firmly against a small, tan one.

Their cave literally shook with the force of Karynth's roar as he finally came. He slammed his hips roughly into Aisu as he held her up, hilting her fully as his orgasm came roaring out. Aisu's squealed her own little rawr in turn, entirely drowned out by her lover.

His sinuous crimson tail lashed and flagged, signalling deep spurts of hot dragon cum into Aisu's womb. Her slit squeezed and rippled with her own orgasm, milking him for everything she could take.

She couldn't take all of it. Not even close. Karynth's cum _glurped_back, spilling out of the wyvern's creampied sex. It drooled down her rump and tail.

Every time Karynth's tail twitched upwards another wave of cum came flooding backwards out of Aisu. The little wyvern's legs trembled and twitched in the air, her paws curling and uncurling.

His orgasm lasted a long time- longer than their last time together, Andari knew. She could tell. She felt aroused at her mate being aroused, by seeing him orgasm so hard. And shame that it wasn't with her. But he enjoyed himself, and that was all that mattered? Andari shook her head, the confusing emotions too much as she watched her mate ride out his orgasm.

Karynth set Aisu back on the ground into a puddle of his own seed. The sticky substance smeared all along the wyvern's backside, making her _ack!_and flap her wing-arms in distress. This only served to get her covered with even more dragon cum.

Andari smiled and giggled at the sight of Aisu frowning at her cum-bloated belly. Her slit continued to ooze dragon cream onto her tail. Eventually the cum coated wyvern sighed and shrugged her shoulders, giving up on any semblance of being clean.

Karynth grinned down at her and stepped to the side, the last dribbles of his seed splatting onto her knee.

"Eugh!" Aisu snorted. "I don't know if I agreed to that! Dragons produce way too much cum. I don't know how you deal with this, Andari."

Andari almost said 'I don't'- because truthfully he never came that hard for her- but the truth didn't seem relevant in this moment.

"You get used to it," she lied, forcing a grin.

"Nope nope nope!" Aisu said, standing as she waddled around the cave. "Oral yes, sex no, for your next birthday Anda. Drakes are ridiculous." The wyvern stopped, looking bashful. "Erm, I mean, I was happy that we could give you your birthday gift, Anda."

Andari met Karynth's gaze and snorted. Karynth just grinned that self-satisfied look of a male dragon who just got laid.

"But if you'll excuse me, I'll be in the lake for later." Aisu waddle-hopped to the cave entrance, leaving a trail of cum behind her tail.

"Later?" Karynth called after her.

"Later?" Andari asked with a squeak.
