‘As I look around the vast hive that is now under my complete control, I still can’t believe I was able to do all this in such a short amount of time. Everyone seems so much happier now, we can finally share love instead of stealing it from ponies.’ A loud hiss echoed behind Thorax, as he daydreamed about how much he’s been able to help the hive just by being himself. The hiss knocks Thorax back to reality as he sees his older brother Pharynx, the only changeling who still hasn’t made the change. He’s slightly disappointed in his older brother, as he drags in a large bag which wiggles in his tight grasp.

“Pharynx, let them go.” Thorax ordered, as the bag opened up to reveal his friends Starlight Glimmer and Trixie.

“Huh, if it was the good old days I would have already fed off their love.” Pharynx gave an audible hiss, as he his younger brother blocked his path from the two unicorns.

“Well that’s why there called the old days, because there old...we don’t do that anymore.” Waving his hoof at the colourful display of not only changelings but the landscape alike.

“Sorry about my brother, he can be a hoofful at times...anyways what’re you two doing here.”

“Other than your brother capturing us and dragging us here...absolutely nothing.” Trixie’s mouth and ego never seeming to stop for even a minute.

“TRIXIE??? Sorry about Trixie Thorax, getting captured by a rogue changeling wasn’t exactly how we wanted to spend our day.” Starlight apologized for her friends brash words, as Thorax wore a face of defeat.

“It’s fine my brother Pharynx doesn’t seem to respect my authority, or the way I’m running the hive for that matter.”

“You need a way to get through to your brother, I’m sure he’ll listen to you.”

“Yeah but, how?”

*One Mole Monster Attack Later*

Thorax just watched his older brother all the way back to the hive, he’d always admired his brother Pharynx’s toughness and appearance when they were younger. But it wasn’t until the change that he saw his brother in a whole new light, still keeping the almost identical colour of a light black with the his brother went from cute to extremely hot. Thorax couldn’t even pay attention to the story, as he lagged a little further behind the group staying just behind his older brother. Every so often with a flick of wind or unconscious sway of his hips, Pharynx’s tail would move just enough to give Thorax a look at his older brother’s tight hole plus his large balls hanging just below. Thorax could feel his mouth begin to water, only imagining how big, his brother’s cock must be just from the look of his balls. His imagination began running wild as he felt his cock begin to slip from his sheath hanging limp between his legs, it wasn’t until he felt his cock begin to throb and nuts begin to ache that he got a wild blush on his face.

“WellguysthatwasreallyfunbutafterabattlelikethatIneedtorestbye!!!” Thorax flew past everyone else, going towards his secluded chambers in the changeling hive. His member now rock hard as he lay on his bed, breathing a sigh of relief just hoping now pony actually saw him. “Why in all of Equestria would you do that?” Thorax whispered at his dick, only get slight throbs and small blasts of pre from the tip.

Taking his cock into his hoof Thorax felt a jolt of pleasure coarse through his body, as he slowly began stroking his length. His mind a fog with lust as his thoughts drifted to his brother Pharynx bent of the bed inviting Thorax to ravage his tight entrance. Just as Thorax was nearing his breaking point, he heard a knock at the door causing him to bolt upward into the air. Wings flapping as he tried his best to find a way to hide his problem.

“J-Just a second.” Thorax calmed down enough to land back on the bed, pull the blanket over his body and cover his throbbing need at least for now. “C-Come in.”

“Hey Bro, how’s it going? You flew off so quickly everyone was worried about you, I told them I’d come check on you. Some of them were scared to disturb you after that little display, so what’s on your mind bro?” Pharynx sat down on the bed beside his younger brother, his flank mere inches away from Thorax’s throbbing member. Thorax could still only blush as he tried to ignore the heat in his loins, sweat poured slightly down the changelings face.

“I’m fine Pharynx, what are you doing here anyways? I always thought you hated me or something...why would you care?” Thorax rolled turning his back to his older brother, trying his best to avoid his hard sensitive cock.

“Hate you??? Little Bro, I don’t hate you. I guess I didn’t really ever show it before, I guess in a weird way I figured one day you’d learn to stand up for yourself if I keep pushing you.” Pharynx could hardly think of what to say or do next, Thorax’s mind was a race with thousands of different thoughts. Pharynx shifted on the bed laying down beside his younger brother, his belly pressed against Thorax’s back. His sheath and heavy balls rested right between his brother’s flanks, just barely separated by a thin piece of fabric.
“Ph-Pharynx???”

“I’m really sorry if I ever made you feel like I didn’t love you Thorax, you’re my brother...I guess I need to drop this tough guy bravado every once and awhile especially when it’s just us.” Pharynx wrapped his hooves around his brother’s midriff, as he pulled himself closer to his brother’s back. Just as Thorax was comprehending what was happening in that moment, he felt his older brother pull away. It took a minute for Thorax to notice where his brother’s hoof had traveled, Pharynx’s hoof laid wrapped lazily around his hardened member. “So that’s why my little brother ran off so quickly, let me guess one of those two mares got ya hot and bothered.” Pharynx gave of a hardy chuckle, still never removing his hoof from his brother’s erect shaft.

‘Come on Thorax you're smart you can think of something...oh what would Ember do in a situation like this?’ Thorax could hear Ember in his mind, yelling words of encouragement and for him to be more assertive.

“Uh no Pharynx, I-I’m going to be honest with you...especially after your trying so hard to be nice to me. Pharynx...I’m gay, and I wasn’t looking at any male changelings...well except one.”

Thorax rolled back towards Pharynx his brother’s hoof still never left his twitching length, as he rolled over and saw instead of anger a surprised blush on his brother’s face. Neither really know what to say anymore, both blushed as they looked into each other’s eyes and without a moment more for his brain to talk him out of it. Thorax lurched forward planting his lips against his older brother’s muzzle, it only lasted a mere second before he pulled away but that second was a moment of pure electrical pleasure coursing through his body. A small tear fell from Thorax’s eye, as he tried to turn away and bite back the tears. Before he could do so however his brother still not removing his hoof from Thorax’s member, used his free hoof to turn Thorax back towards him. Slowly Pharynx inched closer his mouth slightly open, his tongue partially hanging out. As his brother’s muzzle neared Thorax’s brain was working in overdrive with a mixture of fear and lust, turning his head he opened his muzzle slowly accepting Pharynx heated kiss as their tongues wrestled for domination over the other. After several lustful seconds of making out, the two pulled away a string of saliva connected the two siblings lips.

“So...I guess you know which guy I was looking at huh.” Thorax’s face blushed a wild shade of red, as he slightly stammered over his words.

“Yeah especially after feeling this thing, and you telling me it wasn’t one of those mares...I kind of remembered you lagging behind us. I’m guessing you saw something that you liked.” Pharynx gave a devious grin, as he slowly rubbed his brother’s member through the blanket. Thorax tried to bite back a moan as he spoke.

“Uhhhh, Ph-Pharynx, could you do some-something for me?” A mix between a whimper and a moan poured from Thorax’s clenched teeth.

“Sure thing little bro, what did you have in mind?”

“Could you um...Could you maybe let me see your flank again?” Thorax pulled the blanket up a little higher, covering the crimson hue he wore on his face.

“Yeah I guess I can give my little bro a show.”

Pharynx rolled off the bed slowly turning himself around as his hooves hit the floor, first teasing his brother by swishing his tail back and forth. The blanket covering Thorax’s erect member had been removed, as his Pharynx looked over his shoulder eyeing Thorax’s cock for the first time looking into his brother’s eyes he gave a smoldering gaze of pure lust. Finally feeling as though he teased his younger brother enough, Pharynx moved his tail completely out of view. Giving his brother unrestricted access to his most hidden area, a small rounded and untouched hole set slightly above a pair of large heavy balls. Thorax’s bite back a moan as he slowly began stroking his throbbing member, his eyes slammed shut for only a second before opening again. Pharynx was still in the same position only this time Thorax’s eye caught another tantalizing part of his brother’s anatomy, his thick stallionhood pulsed lightly between his legs. His mind a haze with lust he couldn’t help but moan as he continued to stroke his rigid member. With his eyes closed again he didn’t see nor hear his brother’s wings buzzing, as he flew over his brother’s form. Landing on the bed overtop his brother, he gave a toothy grin which Thorax couldn’t see. As he opened his eyes Thorax’s vision was met with a long, thick swinging cock, pressed against the side of his cheek.

“Pha-Pharynx I-.” Before he could say another word his brother slapped his hoof away from his throbbing member, without missing a beat Pharynx dove forward his lips parting as he slammed over half Thorax’s member into his hot maw. “Fu-Fuck Pharynx, I-I did-didn’t know yo-you’d be in-in-into this kind of thing.”
Pharynx simply rolled his eyes, as he gave his hips a pump downward towards his brother’s muzzle. Taking the hint Thorax open his mouth wide, not wanting to hurt his brother Pharynx slowly eased his aching cock into Thorax’s tight, warm mouth. Pharynx pushed his head past Thorax’s medial ring, as he slowly humped into his brother’s muzzle. Finally feeling a little bold himself Thorax started bobbing his head up and down his brother’s thrusting member. In the heat of the moment Thorax took charge for the first time in this situation, wrapping his hind legs around his brother’s neck he pulled him down fully hilting inside Pharynx’s throat. Thorax saw stars as he felt his brother slightly choke on his cock before calming himself and breathing through his nose. Not wanting his brother to feel left out, Thorax used his front hooves to pull his brother flank downward burying his brother’s cock deep in his throat. Both changeling’s gave off a heavy moan, sending vibrations up each other’s cocks as they were both tipped over the edge. A jet of pure white burst from both stallion’s engorged tips, as they lightly humped into each other’s throats riding out their respective orgasms. As the last of their seed shot down each other’s throats, Thorax released both his front and hind legs allowing Pharynx to roll of him, their softening members pulling out with a wet pop. Laying in their afterglow Thorax was the first to speak, realizing rather quickly what he’d just done.

“I-I’m so sorry Pharynx, I never meant to force you like that. It was a complete lapse of judgement, I swear I’ll never do anything like that again. OhyouprobablyhatemenowandyouhaveeveryrighttoI-.” Thorax was cut of as his brother crawled beside him, laying a hoof on his slightly bloated stomach.

“Thorax I’m not mad, in fact I’m proud of you...that’s the kind of assertiveness you need to be a leader of this hive. You took action and control over the situation, for what was in both our best interests. Besides I’ve never been more turned on in my life, I would’ve never guessed my timid little Thorax could be such a dom in the bedroom.” Both siblings members began to harden again, as they lay on their sides facing each other, slowly rubbing their members together bringing both stallions back to full mast. “You know Thorax, I do have one more round in me...and I’ve actually got an idea...if you’re up for it that is.” Pharynx’s voice filled with pure unbridled lust, as he pressed their lengths harder together causing Thorax to slightly whimper.

“Wh-What’d you h-have in mi-mind?” Thorax stuttered trying to bite back his whimpers and moans, as his brother continued to pump their cocks together a mixture of pre lubricating the effort.

Giving his timid brother a smirk Pharynx pulled their sensitive members apart, a string of pre and saliva still connected them together. Thorax gave a slight moan of annoyance at the lack of contact, as he eyed his brother up and down. Turning around Pharynx gave his brother a good look at his untouched hole, using his hoof to spread it slightly open showing off the jet black inner walls of his tight ring.

“You staring at my flank is what brought all this about...why don’t come over here and show me what you can really do?” Giving Thorax a lustful stare and flirtatious wink, hold his hole opened wide for his brother. Taking little time Thorax almost tripped over his hooves trying to get to his prize, getting his first up close view of his brother’s flank and tight entrance Thorax’s mouth began to water. “What’re you waiting for bro? An invitation?” With that smart remark Thorax took to his work, before giving his brother what they both wanted he had an extremely dirty idea pop into his head. Leaning forward he stuck his tongue out, probing inside the tight ring of muscle Pharynx gave off a mareish moan as he was penetrated for the first time. Savoring the feeling of his brother's ring tightening around his probing tongue, Thorax used his magic rubbing a healthy amount of lube over his sizeable length. Giving several probing licks, he was satisfied with his work as he pulled his tongue out of Pharynx’s quivering ring.

Without missing another second of pure bliss, Thorax mounted his brother giving a few experimental pumps of his hips as he tried to find his mark. After a few missed attempts of his tip hitting between his brother’s heavy balls, he finally hit his mark with a heavy moan. Sinking the first two inches inside his brother’s sensitive walls. Pharynx gave a slight whimper, his hole constricting tightly around his brother’s length like a vice. Thorax tried to push more of his length in only to be stopped by Pharynx’s ever increasing pressure.

“Ph-Pharynx...yo-you ne-need to re-re-relax...I c-can’t move.” Thorax stammered through the pure bliss his mind was receiving.

“Yo-You try tak-taking something th-this big your fi-first time...see how we-well you fare.” After several more seconds of agonizing tightness, Pharynx finally took a deep breath relaxing his muscles allowing Thorax to push his member in up to his medial ridge. Pharynx own member throbbed under his belly, slapping against it every little bit smearing pre into his coat.

“O-Okay Pharynx, I’m going to try to do this carefully...just take a deep breath and relax.”

As he felt his older brother take a deep breath and release, Thorax slammed his hips forward burying himself to the hilt inside his brother’s hole. Both stallions gave off a heavy moan followed by a sigh of relief as they stayed connected for a second, Thorax enjoying the tight, warm muscles wrapped tightly around his sensitive cock. While Pharynx enjoyed the feeling of being filled to the brim with his brother’s shaft. Pulling his member out to his medial ring Thorax slammed back into his brother, their balls tapping together rhythmically as Thorax got himself into an even pace. Both stallions could feel each other reaching their limits, Pharynx could feel his brother’s cockhead begin to flare slightly stretching his walls even more, while Thorax felt this brother’s walls tighten around his cock. Pulling all the way out only leaving the head inside, Thorax gave one final forceful thrust into his lover. Burying himself to the hilt as his fully flared, firing of jets of pure lust into his lover. “I Love You, Pharynx.” Thorax screamed as Pharynx was pushed over the edge seconds later, his hole constricted tightly milking his lover’s cock for all it was worth as he fired off jets of cum onto the hive floor. Pulling out of his lover slowly Thorax helped his brother over to the bed, as they laid together cuddling Pharynx gave his younger brother a small lick on the cheek followed by a peck on the muzzle.

“I-I love you too Thorax.” Both stallions blushed as they cuddled each other through their afterglows.

“Phar-Pharynx...what are we now?” Pharynx looked at the worry in his brother’s eyes, a tear forming in the corner as he tried to stop himself from crying.

“What did you want us to be Thorax?” Pharynx wiped the tears from his brother’s eyes with his wing giving his usually fanged grin.

“I-I know I love you...but it’s not the normal love two brothers should have for each other.”

“Thorax, we feed off the love of other living creatures, I mean we’re giant walking rainbows for Celestia’s sake. Nothing about changelings is normal, besides if we can keep having nights like that...I’ll be anything you want me to be.” A crimson hue came across both stallion’s faces, as Thorax gave a slightly devious grin of his own. Just thinking of all the possibilities he and his lover could get into next time, giving a yawn both brother’s fell asleep in each other’s embrace. For now they were not only brothers….but lovers.
