Bottoming Brother

Bottoming Brother

Smolder was more than happy to be back home for Spring Break. Able to enjoy the natural lava pools, the plentiful gems, even the heavy smell of sulfur and ash in the air. Though it was her family that she missed the most during her time away, especially her brother Garble, as the two were closer than any other siblings in the dragon lands.

The first day or so can be described as a pleasant reunion, bonding by the fire and catching each other up on all that happened during their time apart. The following days weren’t nearly as eventful, though, in fact, it was basically them all falling back into their usual routine, and they enjoyed every second of it.

Then the day came that was supposed to be an even quieter day in their family cave, as their parents were once again leaving for yet another trip, this time on a shorter one than average, but still lasting the rest of her stay. She didn’t mind, though, as it meant that she and Garble were left alone to do whatever they wanted. Due to it being a rather slow and boring day so far, she was going to hunt for some juicy gems to take back with her, if not just to remind her of home. Unfortunately, her day out was forced to end before it even started, all because of a dangerously heavy storm that was hitting the Dragon Lands. It was so bad in fact that it blacked out the sun from what she could tell from the cave entrance.

‘Well that puts more than a little damper on my plans...’ She thought to herself as adjusted her hoody and strolled back into the cave, ‘I’m sure mom and pops won’t mind me getting a few from the hoard.’

She didn’t get very far back in before she heard a soft groan from down the hall. She would have ignored it, but she heard it again, this time even louder, and it made her concerned. She followed the sound down to their bathroom, where she was met with the sound of running water not even close to covering the moans and groans.

‘Is that Garble? Is he okay?!’ She thought a brief second of panic as she opened the door, but before she could even say anything, her eyes locked on to the scene before her, and her jaw nearly dropped to the floor.

Through the thin veil of steam she saw a figure clear as day: her brother, and he was clearly not in distress. He was, however, on his knees, face to face with a sizable phallic object hanging from the shower wall. She wasn’t dumb, but she had to do a double take to make sure she wasn’t imaging things, and as the reality of the situation set in. She would have normally backed out quietly but his voice and something within her urged her to stay and watch.

“Mmm~ So big~” Garble cooed to the toy, reaching up and stroking it before giving the tip a slow lick, “You like that, big boy~”

Garble eyes were locked on the dragon-like cock before him, something he apparently manage to get his hands on some time ago, “I want you to fuck my throat~” His voice was lined with lust and need.

Smolder was at a loss for so many reasons but quickly closed the door back to only a crack, ‘He’s talking like a back alley slut... And it’s kinda hot...’ But that didn’t stop the blush from growing across her cheeks, while having to adjust her own pants as she kept quiet and peaked back through the door.

She watched as he stroked it, lapped at it, and sucked along its entire length, from its tip to its balls. Then she watched as it rested against his face as he serviced its sack, a sight she never imagined she’d ever see. Nor did she expect him to arch his back and give her a perfect view of not only his toned muscles, but of his rear, which was a lot more plump then it had any right to be on his form. His moans brought her attention back to him kissing the tip, where his tongue slowly started to coil around the ridged head of the cock.

“Mmmmm~” He moaned as he braced himself and slammed his own head down on the toy, taking it all the way to the base.

She covered her mouth as she gasped, her shorts now bulging from her excitement, begging for attention, held back only by her hand and a zipper. She stares on and sees the slight bulge in his throat as he holds his head down for what felt like minutes before pulling back and gasping loudly. But that gasp for air didn’t last long before he pushed his head back onto the cock, bobbing on it over and over, going down the full length of the toy.

‘Fuck me...’ Smolder’s shorts were holding on for dear life; she couldn’t hold on any longer; she had to drop her pants to let her cock free. So, with quick fingers, she squeezed the button through the hole and let her throbbing member peel her shorts apart, letting them fall into a pile on the floor, all without taking her eyes off her big brother as he fucked himself.

She watched him moan and groan as he audibly slurped on the silicon cock. Before she knew it, she was stroking her own shaft, biting her lower lip, wishing that were her, instead. Imagining him eagerly slurping on her tool, she moaned under her breath as her other hand slipped under her top to start playing with her breast. She eagerly watched on as her brother worked the cock like a whore from a cheap porno, and it wasn’t long before he finally pulled back with another gasp of air, coughing and moaning as his own erection throbbed, untouched, between his legs.

A single strand of saliva remained between his lips and the dripping toy, broken only by the water flowing around him, “I can’t wait any longer! I need you to fuck me~” He moaned to himself as he turned and pressed his ass against the toy.

She watched him brace himself against the opposite wall as he hiked his tail up, presenting his perfectly plump rear to the toy before he pressed it back, hotdogging the cock between his cheeks. She swore she saw them jiggle as he shook his rear, lustfully panting as he readied himself to ride the toy for who knows how long. That’s when an idea dawned on her, a sly smirk grew on her face as she pushed the door open and walked inside.

“Hey~ GarGar~” Smolder said with a slight tease in her tone as she got her brother’s attention.

Garble was dragged out of his fantasy by the sound of a voice coming from seemingly nowhere. His head snapped to the door and he yelped, nearly crashing onto the shower floor as he jumped, holding steady by grabbing hold of the knobs, turning off the water as he caught himself.

“S-Smolder! W-What are you doing here!?” He said through his blush, doing his damnedest to cover himself, “I thought you were going out gem hunting!”

She just leaned against the wall, and as if on queue a loud crash of thunder came from outside, crossing her arms with a smug grin, “I was, but a big storm is blowing through. Can’t go gem hunting in that.” She said as her eyes wandered over her brother's form, “That’s when I heard some groans and decided to check up on you while I was here.”

His red scales turned and even deeper red, “I-It isn’t what you think!” He shouted as his mind raced to come up with some kind of excuse but words were failing horribly, “I was just um... this is...”

“You're joking, right? I saw and heard everything, GarGar~” She said as she spread her legs, revealing the big, throbbing member that’s just begging for attention, “And it made me wonder... Do you wanna try the real thing?”

Garble’s jaw dropped, not only from her question, but at the sight of his little sister sporting a member that was easily larger than his own toy, possibly even a few inches bigger than his own dragonhood. And as the steam from the shower cleared out, the more he saw that made his cock twitch, from her impressive girth to the ridges made purely for pleasure, all the way to her knotted base, which was meant to keep every drop of cum trapped inside her mate. But it was honestly only her size that shocked him, as both he and their parents knew of her anatomy, as it was not uncommon for female dragons to have such appendages.

“So, what do you say, GarGar~?” She asked as she took a step closer, making her cock and balls swing before him, fully capturing his hesitant, yet completely aroused gaze, “No one will ever know, if that’s what you’re worried about.”

He knew he could trust her, but this was something that, in his mind, could get him laughed out of his gang... or even worse: be exiled by all the other drakes, “You... you swear you won’t tell anyone what you saw... right?” He asked, giving in and testing the waters.

She briefly taps her chin before she nods, as if she had to think about her answer, “Yeah, I swear it. I wouldn’t be offering it if I wasn’t going to take this at least somewhat seriously. Besides, you seem to be liking the idea anyway~” She points to his still raised tail and twitching member.

He immediately covered his crotch and tried desperately to push his tail down, all with his face flushed redder than it’s ever been before and his mind racing with the thought of what he should do. It didn’t take long though, as the scent of the shower slowly faded, leaving only the musky stench of arousal emanating from Smolder’s member, mixed with his own scent of excitement. The thought of her cock replacing the fake silicon toy, being able to give him exactly what he wanted, began to poke its way past any logical reason he could muster to reject him. He swallowed the lump in his throat, knowing he may never get another chance like this again, and it’s with the one being he could trust with anything, even his life.

“F-Fine... but only a blowjob...” He said, trying to regain his composure as he got closer.

“Sure, we’ll start with that.” She stated as she took a seat on the edge of the tub in front of him, spreading her legs as she watched him start kneeling before her.

Garble blushed as she got on all fours to get at the right height to be closer with what now had his total attention, as he watched her member throbbed just inches from his face. He slowly crawled closer, breathing in whiff after whiff of the potent musk emanating from her rod and heavy balls, silently drawing him in even more. His hesitation faded as he realized her cock was now resting against his face, his nose eagerly pressed against the heavy sack below.

“It’s been a while since I last drained them, so I have plenty to give you, GarGar~” She said as she slapped her cock against his cheek.

He shivered as he felt the heat from it pressing against him, unaware that his tail was lifting on it’s own as his nervousness resided. He then stuck out his tongue and gave her cock a long, smooth lick along the whole of her shaft, the warmth alone was already so much better than the toy he had stuck to the wall. He heard her moan as he began lapping at her shaft, growing more and more eager as he worked, loving the tastes sliding along his tongue as it traveled over felt every ridge and spine.

“Mmm~” He moaned as he reached her very tip and closed his lips around it, suckling tenderly upon it as his hand began stroking the rest of her shaft.

“Damn, Garble~ Looks like that practice is paying off.” Smolder groaned as she felt her brother giving such attention to her dragonhood, adapting much quicker than she expected.

He felt a hint of pride and doubled his efforts, bobbing his head on the upper half of her shaft, the thickness already being more than what he’s used to. His eyes went lidded as he pulled back and licked his lips, savoring the taste of her meat before he moved below the towering spire to press his nose against her balls. He took another heavy sniff, the realness of them making him even more excited, and making his own cock leak between his legs. He slowly opened his mouth and pulled her massive balls into his mouth, rewarded by another groan of pleasure from his sister.

“Mmm~ You don’t wanna leave anything left out, do ya?~” She cooed as she enjoyed the service on her balls, her cock twitching as she felt his tongue dancing over her sack.

He cradled the weighty orbs in his mouth, loving how big they were, knowing they were full of the seed he was going to drain from them. His saliva coated them heavily as he pressed his face even further against them, releasing them with a soft moan just to feel them brushing against his nose as they swung free. He looked up wantonly at her full length before going back up to her tip, trailing his tongue along her underside of her shaft before slipping it back into his mouth and began bobbing once again, only this time he pressed further with every bounce, sliding inch after inch into his eager maw.

He felt more and more filling his mouth, expecting to take it all just as easily as he could take his toy, but after another moan escaped him, he felt her cock reach the back of his mouth and he paused, his tongue coiling around the behemoth inside of him. He then slowly opened his eyes and saw that there were still several inches to go, the sight alone causing his cock to shoot pre in excitement.

‘Fuck... she’s so big... I want it all~’ He thought as he stroked the base even faster, pressing his mouth as far as he could go, slowly adjusted to the side as he went even further.

He eagerly began bobbing his head harder, moaning even louder as he felt her cock twitching and leaking drops of pre against his tongue. The salty, masculine taste made it that much better, encouraging him to suck even more intensely, working to get as much of her delicious pre as he could, each pulse rewarding him for his efforts. He eventually pulled back to pant heavily, catching his breath while his hand kept pumping, only to feel her hands grab ahold of his head.

His eyes grew wide before he gagged as he felt her cock thrusting straight into his throat. His hands reflexively grabbed hold of her hips, but it did nothing to stop her as she held his head firm, her cock bulging his throat far more than his toy ever could. He huffed as he began to breathe through his nose, held right up against her crotch.

“Fuck~ Sorry, GarGar, I couldn’t wait any longer~” She groaned before she started pumping her hips, fucking his face.

Garble’s eyes rolled back and his arms went limp as he lost himself in the rough treatment, loving the feeling of her fucking his throat like he was a discount whore. His tongue eagerly lapped at her cock each time his nose wasn’t pressed against her, while the girth of her cock stretched his moaning throat, moaning purely from the pleasure of giving her pleasure.

“Oooh~ Such a tight throat for a slut~” She grunted as her hips picked up more speed, smoke beginning to trail from her nose as she reached her full power.

He gagged and moaned as she abused his mouth, feeling the strings of pre sliding down his throat. His body shook as he heard her call him a slut, his hands grabbed hold of his cock and started stroking it rapidly. His breathing became a struggle while she pinned him more and more harshly, harder and harder as her balls repeatedly slapped against his chin. He couldn’t stop the sounds of enjoyment mixed with the loud slurps that he made as he worked with her pounding his face. His tongue was still trying to taste every single inch of her cock, not leaving any of its flavor untasted. Her knot was finally filling his mouth when her tip slid down to its deepest depth yet, it was all he could think of as his cock was ready to burst.

Smolder let out a growl, wisp of fire trailing from her mouth as she gave one hard, final thrust, slamming Garble’s head against her base as her wings proudly flared and she shot off load after load of her cum down his pulsating throat. She could feel him eagerly gulping down each and every shot of her seed, she looked down and thrusted her hips once more at the sight of her brother’s lust-filled face, making her climax even better.

‘Mmmm~! So much~’ Garble’s mind raced as he let go of his own cock, leaving it twitching with need, and focused purely on swallowing as much as he could, ‘I... I want to taste it.’

As if she could read his mind, Smolder relaxed her grip on his head and pulled back to let her cock rest against his tongue as she rode the last few waves of her climax. After so many months without a proper release, it had been building up far more than she thought, and what a way to go, shivering as she felt her brother’s tongue lapping at her tip, with his mouth locked around her shaft.

Garble took a deep inhale through his nose before letting out an even louder moan as his mouth was being filled with her cum. The taste was overwhelming, and he carefully swallowed each mouthful without a single drop leaking from his mouth. The flavor was potent, keeping his mind spinning in lust, as he suckled her tip not wanting the stream of seed to end.

“Fuck, GarGar~ You got the mouth of a trained whore~” She sighed, watching his eyes slowly blink as his mouth rolls over and over with his loud gulps.

She loved how his tongue stayed coiled around her shaft, gently sucking to get every bit he could. She wouldn’t have minded having him stay there, mouth locked around her cock, just drinking her orgasms one after another without end, but as she looked past the dreamy expression on his face, she saw his rock hard, throbbing cock between his own legs, just oozing pre, and she knew he wanted more. The very fact that he was about to fuck his own ass with his toy not minutes before was proof enough of that, and she didn’t want to stop their fun.

She pulled back and watched as he gasped, filling his lungs with more fresh air while keeping his head as close to her cock as he could, “Good job, GarGar~ Licked it clean, too~” She lightly pressed her half hard cock against his cheek.

Garble panted and whimpered as he felt the saliva slicked member rubbing against him, dropping precious drops of cum against his face, making him throb as his tongue rolled out to get another taste. He moaned as he felt the cum sliding along his face, and even more when he licked it up, savoring the taste, rolling it around on his tongue, so much so that he had almost completely forgotten about his own erection. He looked up to her with need, he could feel her holding his cheek while she pressed herself against him. He wanted to go all the way, his cock was desperate for attention, but he needed that long, girthy cock inside of him even more.

“You want more, don’t you?” She teasingly asked him, knowing he was too far gone to answer. “Show me how much you want it~”

Garble shivered at her tone and took another deep whiff of her scent before standing and moaning as his cock brushed against her, sliding a string of pre from his tip. He turned and put his hands against the shower wall as he raised his tail as high as he could, spreading his legs as he put his ass on full display for her.

“Damn~ Never knew you had such a big, juicy rear~” She purred, admiring the sight of his bare, thicc ass.

Garble had always been a big guy, well kept, strong, tall, and handsome by almost all respects, though most never noticed that his rear was just as big and toned as the rest of him, due to the fact that he kept his broad tail as close to his rear as possible. Now though, Smolder was given a view only his mirror had ever seen before, and she couldn’t take her eyes off of it. She couldn’t help but press her hand against his cheeks, widening her eyes as she felt how easily her fingers sank into the supple scaled rear, and biting her lip as she groped and played with the beautiful, bouncy rear before her.

“Mmmm~” Garble moaned under his breath as his own little sister played with his surprisingly sensitive rear.

She released one of her hands, raising it up, only to slap it back down against his ass, sending an echo across the room, followed immediately by her brother’s gasp of shock, and a long squeal-like moan, the sound of which was music to her ears. She wasted no time in raising her other hand, and slapping it against his other cheek as his tail eagerly wagged in her face. His wings snapped open as she laid a few more slaps against his pudgy back end, flapping lightly from his enjoyment of his younger sister simply playing with him in such a way.

She smirked as she watched his ass bounce and jiggle from her constant slaps, making her cock twitch as he pushed his ass towards her, giving her even easier access. She licked her lips as she saw everything he was offering her, especially when she saw his tight, pink pucker.

“Now that’s an ass any drake would love to breed~ Ain’t that right GarGar~” She said as she watched him wither from her simple actions, “Yeah, if you just showed it off a bit more, you’d have a whole line of dragons wanting to have a turn with you... But right now I have you all to myself~” Her tone teased him almost as much as the finger she was rubbing against his pucker.

Her words alone were making him groan, at least before he let out a whine as she prodded his entrance with a single finger as she started playing with his cheeks again, “S-Stop teasing and do something...” The thoughts from her words made his cock throb between his legs, leaking onto the shower floor.

“Oh, don’t you worry, I’m getting to that, you needy slut” She slapped his ass again as she took in the position they were in. ‘Damn, too high up to fuck right now... but that isn’t the only way we can have some fun~’ A grin crept across her face as she spread his cheeks, exposing his full, twitching pucker to her hungry gaze, “I just gotta get you ready”

She grasped at his rear tighter as she closed the distance to her target before plunging her face between his cheeks, her mouth pressing against his hole, her tongue immediately starting to lap at his entrance, earning a gasp before a long, hearty moan. She, herself, moaned as she felt his cheeks twitching against her face as she teased his pucker, her hands still running across his backside as she worked, pressing her tongue against him, gently piercing him, slowly entering the warmth of his passage, before eating him out like her life depending on it.

“S-Smolder~ AH!” His words ceased as she slapped his ass once again, abusing his tender, sensitive flesh with her sinful strikes before she did something he never expected: she reached between his legs and began rapidly stroking his cock.

He fully dug his claws into the wall, the sensations of her tongue invading his ass and her hand pumping his cock was overtaking him. His tongue rolled out of his hanging mouth as he felt her tongue sliding so deep inside of him, her saliva coating him, preparing him for what was to come.

Smolder didn’t dare to pull back as she motorboated his cheeks, never stopping her quest to reach as far as it could with her tongue, occasionally brushing against his pleasure center. Though she only knew she hit it when she heard him squeal and clench on her narrow tongue, though if she was more acute, she might’ve felt more pre oozing across her fingers than before. Her cock throbbed with excitement as she prepared him for the main event, knowing she was mere moments away from fucking his juicy ass, from feeling it bouncing against her hips, but it had to wait as she continued her dive.

She slapped him again, earning a rather loud moan as the tip of her tongue ran along every inch of his passage hitting every spot that made him whither, and, as a final jab, her hand finally doubled its efforts on his cock. She felt him pushing back against her face and thrust against her hand that pumped his shaft with vigor, as she pressed her face more against his bubble butt. His moans grew louder than before, his hips thrusted back as hard as he could, forcing her head against the opposite wall as his cock pulsed wildly in her grasp, firing off heavy ropes of seed.

“AHHHMMMA!” Only moans and cries of a common whore could match the sounds he made as he ground himself against her tongue as he rode out his orgasm.

The scent was strong and just potent as hers as it shot across the bottom of the tub, each shot coating her fingers further as she slowed her plumps. She moaned into his cheeks, more than happy to be between them as she continued to enjoy his rear. He nearly collapsed by the end of it, his legs feeling like jello as the hand on his cock finally ceased. The hand on his rear, however, was still working him through, groping and kneading him as if she owned him, making his cock twitch at the thought.

“Mmmm!” Smolder hummed as she pulled back, giving his ass another smack as she pushed him off of her face, grinning as she gazed upon her work.

Garble was leaning against the wall, face planted against it as his legs were buckling into one another, his tail hanging limply to the side, doing nothing to hide his now dripping backdoor. His cock oozing cum from his orgasm, coated in his own seed from her fingers being covered in it. Her gaze then trailed its way back up to his face, meeting with his eyes, the submissive and needy look he gave her, along with his still rock-hard cock confirmed that they still have plenty to do.

“Ready for more, GarGar?~ Ready for your little sister to finally claim your slutty ass?” She asked, her tone just as teasing as before as she grabbed his ass even harder.

A long whine escaped him, and he could only nod at first as his legs shook yet again, “Y-Yes... Please... I want to...” His eyes trailed down to her cock as he licked his lips, the taste of her seed coming back to him before he cleared his throat, “I...I need a replacement for that, you know...” He said as he steadied himself, all while keeping his ass pointed at her.

“Anything for my big bro. Let's take this to my room~” She told him as she stepped out of the shower and motioned for him to follow her.

It only was a few seconds before they broke off to her room just down the hall, and as they entered, she grabbed him by his waist and held him firm as she groped him. The dynamic of the tough and protective big brother with his sweet yet feisty little sister was beyond gone at this point, and they both knew it. Even though she only stood as tall as his chest, she was in total control, and could easily overpower him with pleasure, all thanks to her catching him in the act.

“On your knees GarGar~ Only way to fuck it right!” She slapped his ass, pushing him onto her bed.

He jumped forward and moaned, feeling the effect of her slap against his rear as he knelt before her bed, resting his head against her mattress. He swayed his ass at her, tail as far to the side as he could, giving her as easy access as he could, leaving him blushing through his scales yet again. Anyone could just walk in and see him so exposed, so willing to be pushed around by his sister, and they would laugh, but he was enjoying the thrill too much as he pushed the thoughts back.

“Perfect height~” She purred as she stepped up behind him and slapped her cock between his cheeks, groaning as her cock was hotdogged between them, “To pick up where you left off~”

He would have snapped back at her for that, but he could only moan as she ground against him, causing his protest to die before it could be raised, “F-Fuck...”

“Think it’ll fit? It’s a bit bigger than that toy you were using.” The dragoness smugly stated as she slapped her cock against his ready and wanting ass.

“Y-you better make it fit.” He sharply replied, gripping her sheets as he felt her pressing her tip against him, “We ain’t leaving here till...”

“Till what?” She harshly yanked his tail, shutting him up, “You’re not in a position to tell me what’s gonna happen, GarGar. You’re the one I caught moaning like a slut, begging to be fucked like a dragoness in heat, working as hard as she can to please a cold piece of fancy plastic, desperate for something that can thrust back!”

She thrusted her hips against him, slamming against his rump and earning low groan from him as she kept her teasing. She made sure to rub her cock directly against his saliva slickened hole, forcing her cock’s bumps to tease the rim of his backdoor, making his body shake and his wings twitch against his back.

“So... what does my big, horny dragoness have to say now?” She spoke in a hushed tone as she reeled back and teasingly pressed her tip against his entrance, “You want me to fill your boy-pussy with my big, hard, throbbing cock?”

Garble felt the power in her words, the heat of her shaft alone being enough to never want to go back to the fake one, “Y-Yes... Please...”

“Louder, like a good dragoness~” She ordered with a slap of his ass.

He let out a whimper before he looked back at her. “Stuff my boy-pussy! Fuck me like a whore!” His voice was coated in need as he pushed back against her.

“Good girl~” She gave one final tease before she thrusted her hips forward.

He gasped as he felt his little sister’s hot dragonhood finally burying itself inside of his ass, each ridge and bump rubbing along his entrance as she delved as deep as she could. He moaned as he felt himself being stretched wider than ever before, far more than his toy ever could, and she still pressed even deeper. He cried out in pleasure as he felt her knot briefly pressing against him, then immediately entering him, her hips were now flush against his ass, and, with an audible smack, they met.

“F-Fuck! For a whore, your ass is tight~” Smolder groaned as she rolled her hips, shifting her shaft around in his clenching passage.

Her hands grabbed his hips, both securing her place and groping his rump as she hilted herself inside of her big brother’s warm, inviting ass. It felt like his whole body was trying to milk her cock as much as it could, and with his moans and shivers, she smiled as she was about to give him everything he wanted.

Garble’s mouth hung open as he let out long drawn out moans and groans of satisfaction. He felt each and every pulse and throb of her cock as it was buried deeper than he had ever experienced before. Its girth and its length could only be described as amazing, and as she hilted herself inside of him, he felt her balls press against him, a feeling he never knew he wanted, being still so full of cum to give. Not to mention the heat: her knot gave so much heat as she stretched him even further, stuffing him all at once.

“N-No~ you’re just... Oooh~” His sentence was cut off as her cock rubbed against his prostate, destroying his words before they could form.

Smolder gritted her teeth as she felt his hole tighten itself on her shaft, “I think I hit the mark~” She then huffed as she pulled back and thrusted again, watching her brother’s ass bounce against her hips.

Garble gasped at her thrust, feeling the rough smack of her hips against him, and he couldn’t help but push back against her, helping her back in, then she pulled back and thrusted again, quickly developing a rhythm as he simply moaned out loud. Her balls slapped against his own every time she buried her cock inside of him, and her hands squeezed his rear just a bit harder as she pulled out, making him whine every time she did.

“S-Smolder... mmm~” He finally managed to speak between his grunts of pleasure, “You’re just so big!” His voice hitched as his ass was pulled back against her.

“You’re still a tight bitch,” She said with a light growl as she held a tight grip on his rump as her rhythm picked up more and more, “ I’m gonna love loosening you up~”

The room echoed with the repeated slaps of her hips against his ass along with the scent of their musk filling the room, exciting them further into the depths of depravity as she plowed her brother into the sheets of her bed, feeling his passage pulling her back in with each thrust. She couldn’t help but slap his ass to make him moan louder, the sweet sound was music to her ears, combined with the eye candy that was watching his rear jiggle every time her hips collided with his, and the fact that she could feel her balls swinging and slapping against him every time she moved, she was loving every second of it.

“Fuck~ You like that, don’t you, slut~?” She groaned as she reluctantly slowed down, trying to kept it as slow as she can, not knowing how long she can keep it that way, “I wanna hear you say it~”

His whines were low and needy, his hands were gripping her sheets as her thrust were balls deep each time. His body was shivering, feeling her knot gently popping in and out of him every time she thrusted, and how he kept clenching against it every time she slammed it inside of him. The feeling of his backdoor being stretched further than he thought possible made his cock pulse, as he enjoyed her girth and length more than his toy could do.

“D-Don’t stop... Ah! I... I want it~~” He mewled as his body rocked, pushing himself back against her.

He cried out as she slapped his ass once again, “Want it more than that useless toy of yours, uh?~ Well, I’m gonna make sure you can’t even think about anything other than my cock after this~” She growled as she shifted and pressed herself down on his lower back.

He let out only a drawn out cry out as she suddenly picked up her pace, her cock now slamming against his prostate with every thrust. His back arched, claws digging into the sheets, tearing them to shreds as he truly cried out like a dragoness in heat. His ass was being used like a cheap sex toy, and if the pulsing, throbbing cock beneath him was any indication, he was loving every second of it.

The sounds of his cheeks clapping against her hips only excited them both more, the mix of their moans and the bed shifting, “You love having your sweet, little sister fucking your big, slutty ass, don’t you?~”

“AH! MMMM~ GAH!” His wails of ecstasy only grew in frequency as she talked to him like she owned him, “Y-YES! I-I love your big, j-juicy cock~!” His words meant everything in that moment.

Smolder bit her lip at his cries of admittance between his pants of pleasure as she held tight to him, using him like he had been begging to just a short while ago. “Good, cause your boy pussy’s better than any fleshlight I’ve ever used!” She grunted as she gave his tail a hard pull, earning yet another lust-filled cry.

Her cock was about to burst, wanting to breed his ass like it was hers to own. He was her dragoness, her mate to flood with hot fresh cum and fill with her clutch. The thought made her double her power, crescendoing the sound of their bodies slapping against one another as the various juices leaked out from around her cock, coating her shaft and balls.

‘B-Breed me! I need it~’ Garble’s mind was a haze, locked onto the dragoness fucking him into her bed, his cock just dripping precum all over the ground below, ‘I can feel her pulsing, so much~ oooh~’

Hot wisp of fire left their mouth as they couldn’t hold back any noises of their otherworldly satisfaction. Their bodies and minds only felt the need to breed and be bred, and they cared not for their roles being switched or their biological relation, as the thrill was all that mattered.

“B-Better be ready for it, slut! CAUSE I’M NOT PULLING OUT!” Smolder growled as she quickened her pace, fucking him as hard as she could, quickly reaching the point of no return, and ploughing right through it.

Her balls tightened up to her body, her muscles twitched and clenched, and her mind was filled solely with her brother’s succulent, doughy ass as she pressed her, and her chest against his back, holding him as close as she could.

He felt like he was going to pass out, being filled with such incredible pleasure that he only ever dared to dream about, yet never knew how wonderful it could be, and after all these years of his secret desires, he had finally gotten it. A real cock was filling his ass, real claws were gripping his hips, all while her breasts were pressing against his back, reminding him exactly who had given him everything he had ever wanted, and how taboo this situation was, in their minds it only added to the intense thrill.

She slammed forward as hard as she could, smashing herself against his ass like she was trying to break it, shifting him further up on her bed, and driving herself all the way to her base as she came.

His legs would have buckled at her final thrust if he wasn’t already on his knees, overwhelmed by her sudden burst of power, then awed by a feeling he had only ever dreamt of before. He felt her knot growing inside of him, locking him in place, keeping him bound to her as she unleashed wave after wave of cum inside of him, filling him to the brim with a hot, passionate heat like he’s never felt before. It was all so much, and with his cock now pressed against the sheets, he came, releasing all of the built up desire into each surge of his seed upon her bed.

“Oooh~ Mmm~” Smolder felt her brother’s ass clench as he let loose his own eruption of seed, the feeling of him clenching around her length only made her orgasm last that much longer, being drained by her needy dragoness.

Time seemed to lose all meaning to them as they laid there, glowing in peaceful bliss, bonded together in wondrous lust.

It took longer than either had expected to come down from the unbelievable high. Garble panted heavily, his body constantly quivering, still reacting to the small bursts of pleasure he got from every miniscule movement. Smolder caught her breath quickly, and straightened herself up, groaning softly as her cock was still buried in her slutty brother's ass, the grip of which she was more than happy to stay bound by, at least for a little bit longer.

He looked back, biting back a moan as he felt the last dripples of cum leaving his cock, joining the mess between his stomach and sheets as he shifted. But that was nothing compared to the fresh seed trapped inside of him, accentuated by Smolder as she gave a teasing thrust of her hips, groaning openly as her hand groped his cheeks.

A few more moments passed before he managed to relax enough for her to pull herself out with an audible pop. She shivered as her cock was now exposed to the cold cave air and Garble moaned as she left, gripping her sheets as her cum now oozed from his freshly used hole. He cooed, feeling her seed run down his balls and his legs pooling on the ground below, a sight Smolder couldn’t help but lick her lips at as she admired her work before moving onto her bed and falling onto her back.

Garble moved much more slowly, his strength just coming back, and pulled himself fully onto the mattress, hugging a pillow close to him as he let his abused rear rest. They both laid there in silence for a while longer, their breathing fully relaxed, content looks on their faces.

Smolder felt herself more exhausted then she expected, “Only two orgasms and I’m totally wiped... But it was one hell of a good time, GarGar~ Maybe we can do it again before mom and dad get home, might take a while with the weather. Would you like that? My balls slapping against your ass, breeding you like a dragoness in heat~ Or we could wait for tomorrow, where I can wake you up with my cock stuffing your throat~”

His face was back to a full blush, “Hey! Just ‘cause you got a big dick doesn't mean that I’m just gonna...” His half hearted rant was cut short by a sudden burst of light.

There, just above the two of them, was a letter, and it was gently floating down to Smolder, who quickly caught it and, when she saw the School of Friendship’s seal on it, ripped it open and started skimming it out loud almost angrily, having been interrupted so rudely.

“Dearest Students... yadda yadda yadda... hope you’re enjoying your vacation... yadda yadda yadda... an... unforeseen weather event? And I’m hereby extending spring break until further notice?”

The rest of the letter was pointless to her, and as her voice faded with those words, Smolder sat up and grinned even wider as she looked to her big brother, “Well, well, well~ Looks like this big dick’s gonna be here a while.” Her free hand was now stroking her formerly softening member, “Good thing, too, since you’re gonna need a replacement for that useless toy of yours~”

He watched as her hands rubbed along her hardening shaft, a sight that caused his own to slowly come back to life, “Well... as long as you’re offering...”

He shuffled himself over and replaced her hand with his own, pumping her rod back to full strength as he gave it another long, slow lap, trailing his tongue from her base to her tip, and just as he reached the end, he glanced up to see an approving smile.

“This break just got a whole lot better~”
