Rumble may have grown into an adult (albeit, a rather femmy one), but he never stopped admiring his brother Thunderlane. Except now, the twinkish stallion's admiration was much more mature. Hopefully, some girlish clothing might make him take notice.

This story is the official winner of my July 2018 Commission Story Poll, in which Top-Tier contributors can submit possible story prompts for each month as part of my Patreon.
This month's winning story was suggested by NFreak, and is blatant M/M smut featuring Thunderlane and an aged-up Rumble. This story contains strong sexual themes which include incest, daddy play, crossdressing, sex toy usage, small penis humiliation, oral & anal sex, and a twinkish femboy playing with a thick, daddy-grade stallion. Reader Discretion is advised.
Also, the cover page is obviously not mine. If you want to check out the artist, look up Hoodie on Derpibooru and give them some love.

Over the years, Thunderlane and his younger brother Rumble had grown up quite a bit, and in significantly different ways. For Thunderlane, his time as a member of the Wonderbolts stunt team caused his body to grow quite acustomed to eating large quantities to make up for his strenuous physical activity; this meant that whenever he was off-duty and away from Wonderbolt practices, it was easy for the pegasus to bulk out and grow a rather... Daddy-like figure across his well-aged form.
However, his brother Rumble ended up carrying a much different physique after puberty set in. By the time he had grown into a full adult, the younger stallion had remained deceptively slender to accentuate his very... very feminine-looking appearance.

But despite how girlish he may have looked, Rumble couldn't have asked for a better type of body to show off his curvy features. However, even with all the pervy looks he received over the years from all kinds of guys, Rumble's heart was always set on the very stallion who remained a caring brother over the years; unfortunately, Rumble knew he needed a surefire way for Thunderlane to not only notice his affections towards him, but to actually accept them despite their blood relation.

Luckily for the femmy pony, he had plenty of makeup, girly clothing, and rather naughty toys to help catch the gruff Wonderbolt's eye~

AKA, Rumble Wants A Tumble

“Mmmmphh! C’mon, you… you stupid strap!”

Rumble groaned bitterly as he sat alone half-dressed, and fully peeved at the time restraint he knew he had. The grey pegasus may have had the door to his bedroom locked, and even made sure he was alone in the house before doing anything, but he still tried to keep his voice low as he struggled with his attire. His teeth were tightly gritted in frustration, and his face was growing red while trying to pull the remainder of that pink pantyhose up his hind-legs. “Nnnnghh! I swear,” he muttered annoyedly under his breath, “If Rarity’s measurements are off, I better get a refund on these…”

Despite how thin his limbs may have looked, especially alongside his slender-looking torso and overall girlish figure, the limits of the mare-made material’s fabric were quite apparent the instant they tried to wrap around his thick and meaty thighs. The plastic straps may have been stretched out far enough to reach the bottom hems of his pink panties, but it would’ve taken a miracle to ensure they would stay on against the tension of those plump, full-bodied cheeks. While he was sure in the end it wouldn’t necessarily matter, Rumble wanted to ensure he looked his absolute best before his brother came back from picking up dinner.

As he looked down and saw how high those pantyhose were riding up his legs, Rumble paused briefly enough to close his eyes and sigh to relax. Even though he knew how quick Thunderlane could be when running errands, he didn’t want to risk tearing up his leggings when he didn’t think to buy any spares. Not to mention, after all the months he spent just fantasizing about this sort of night happening, he didn’t want to grow too anxious about the preparations and squander the only opportunity he had. After managing to control his breathing for a good ten seconds, Rumble felt his thick leg muscles relax enough to allow him to hook the straps in their proper place.

The pantyhose may have been stretched well past their limits to cover his full-bodied legs, but the pegasus couldn’t have cared in the slightest when he stood up and felt how secure they were. He looked over towards the mirror at the corner of his room, and blushed with an elated smile when he saw just how tight the panties were wrapped around his juicy rump. He may have been skinny as a rail compared to his Wonderbolt brother, but there was no doubt that he could give any slutty mare a run for their money when it came to the booty. Has Thunderlane ever said anything about it? No, but Rumble couldn’t necessarily blame him due to their blood relation.

But did he want Thunderlane to notice how tantalizing he looked in such a feminine outfit? Abso-fucking-lutely~

After admiring his plump rear for another moment, seeing just how tightly that pink cotton hugged every curve of his cheeks (not to mention that accented bulge of a little something extra he had hidden underneath~), the pegasus shivered in delight before reaching for the remaining items for his outfit. In a strong contrast to what was donned around his lower-half, Rumble had a very loose-fitting, and bright pink half-shirt to wear over his slender torso. He also had a couple pieces of clip-on jewelry to place on his ears, which were surprisingly easy to put on despite not having unicorn magic. Even though he knew he already looked tempting enough for any curious stallion’s lustful gazes, Rumble knew there was one last thing he needed to really ensure Thunderlane would be interested: a simple thick, red hair-band that he used to tie up the back of his shaggy mane, and make it into a cute little ponytail.

Over the years, Rumble had learned more than enough details about his brother’s interests to get a good idea what turned him on. Unfortunately, it was always a bit aggravating to try and adhere to so many of those details for himself, but barely get much notice from the Wonderbolt when they were alone. Even when he tried to act especially flirty with the cover of “being a little too tipsy,” his honest admissions were usually just passed off as the behavior of a drunken twink. But with the two of them alone tonight, and his body especially needy for some admiration, Rumble knew that he couldn’t just flag down some random stallion again to sate this itch; this time, the only pony he wanted to scratch it was the one who was just about to come home.

By the time he was about to apply his makeup, Rumble jolted a little when he heard the front door open downstairs. “Yo, Rumble!” shouted Thunderlane with a cheerful tone as he re-entered the modest Ponyville home the two shared. “I’m back with the pizzas! The guy who took my order screwed up one of them and had to redo it, so I got a free order of cheesy-bread!”

Rumble’s brows raised a little as he shrugged happily to that addition, but he stayed diligent while trying to quickly apply the mascara along the rims of his eyelids. “Th-That’s great to hear!” chirped the femmy pegasus while perched in front of his mirror, hopeful that his brother would stay downstairs until he was ready. “I-I just need to freshen up a little bit! I’ll be right down!”

Rumble wasn’t sure if his voice sounded too rushed or frantic, but he couldn’t afford to stop his work when he was so close to completion. Even though he didn’t hear anything to indicate Thunderlane was coming up the stairs, the younger brother applied the remainder of his makeup in record time just in case. The mascara and expanded lashes around his eyes made them look absolutely inescapable, ensuring that Thunderlane would have difficulty turning away from his purple haze up-close. His cheeks carried a deliciously pinkish hue, which made his face look much fuller and younger than before. And that ruby-red lipstick was flawlessly painted across his already pillowy lips, helping to make them look even fuller and more tantalizing.

Of all the things Rumble would’ve been encapsulated by after he finished preparing himself, it was the sight of his lips that made him shiver with an antsy grin. He knew he wasn’t likely to see them in action himself, but he could only imagine how they would look wrapped around Thunderlane’s thick, meaty shaft tonight. Meanwhile, his wings fluttered involuntarily while sticking out beneath the back of his half-shirt, slowly becoming fully unfurled in arousal. While he knew that shouldn’t be the only indicator that he was turned-on, he was doubtful his brother could notice much between his legs while constrained by his panties.

He wasn’t sure how long he stayed upstairs in nervous wait, admiring how elusively hot he looked in front of his mirror. However, he was quickly thrusted back to reality when he heard Thunderlane shout out, “Rumble, you done yet!? The pizza’s gonna get cold, dude!”

“C-Coming right down!” he blurted with a brief yelp, the surprise of the moment causing his natural blush to come through stronger than the makeup’s blush. Nevertheless, the slender pegasus shuddered with a quick breath before he began to exit his bedroom. While he was upstairs, he had to pause for a split second to collect himself, and hope his nervousness would slip away the instant he went down those stairs. Fortunately, Rumble knew he had one final ace up his sleeve that he prepared while his brother was out of the house; he knew it would be weird to try out, but it was now or never as he stood at the top of the stairs and out of the stallion’s line of sight. “Uhhh… Thunderlane?”

Meanwhile downstairs, Thunderlane had already gotten himself accumulated with dinner as he sat on the couch with an open pizza box on the coffee table. The dark grey stallion may have been a Wonderbolt during the summer season, but he looked absolutely different now that he was enjoying his off-season leave. Along with the husky figure that ballooned out due to his unchanged diet (which he lovingly referred to as being a ‘muscle-gut’), he had also refrained from shaving too often. He was still undeniably attractive, even with his silver mane carrying a salt & pepper vibe as it greyed in various spots, but he almost looked like Rumble’s father instead of an older brother. Nevertheless, the pegasus paused while a slice of pizza was in his hoof before replying to Rumble’s voice upstairs.

“Yeah, bud?” he asked as he leaned back against his couch, and took a quick bite of that buttery pan-crust.

“Uhhhh… I kinda… have something to give you, bro~” Despite how sheepish Rumble’s voice sounded, there was the slightest hint of something suggestive beneath the surface. Thunderlane’s brows raised a little with curiosity as he chewed on his slice, unsure what his brother was getting at. Meanwhile, Rumble took a couple seconds to recompose himself before adding, “Umm… Could you maybe… check that note I left for you on the side of the couch?”

“Hmm?” Thunderlane became confused, not recalling seeing anything when he came home with their food. Alas, he let out a quick “Oh!” the instant he glanced over at the armrest of the couch, and noticed an odd-looking piece of black cloth holding a piece of paper in place. He groaned a little as he leaned himself over to pick up the paper and cloth, and shouted up towards Rumble, “Found it!”

While his brother waited upstairs anxiously in his attire, Thunderlane opened the paper up to read what it was written in red ink:

Thunderlane,

Put on the blindfold after reading this. I have a surprise for you~

Underneath that brief and lustrous message was the imprint of a kiss, made from one of Rumble’s cheaper lipsticks. Upon seeing that addition, Thunderlane's eyes widened immensely. After thinking for a second or two, his face lit up before asking, “Rumble, did you get me a girl or something?!”

Even though he knew he didn’t give any strong hint that he was supposed to be the ‘girl,’ Rumble still groaned briefly while upstairs in his getup. However, he sighed with a roll of his eyes and replied, “Umm… K-Kinda?~”

“Oooh, sweet!” shouted the older pegasus downstairs, whose excited tone was more than enough to get Rumble into slightly higher spirits. As he waited for a moment to see what his brother did next, Rumble double-checked his pantyhose before hearing him call out, “Okay, it’s on!~”

Thunderlane may have been hungry, but the prospect of getting some action overpowered the smell of that pizza wafting from the box before him. As he finished up his slice, the stallion was giddy enough to almost begin bouncing on the couch in wait. Since he was already undressed, he didn’t see much harm in letting himself relax a bit as he spread open his legs. After all the near-constant lays he received during Wonderbolt season, the pony knew he needed some action to counteract his recent dry-spell.

Meanwhile, his ears twitched as he heard the faint sounds of hoofsteps coming down the stairs. He wasn’t sure if it was his brother or the girl he hinted at, but Thunderlane’s member still stirred from its sheath as he began to grow more enticed. By the time he heard the pony come down into the living room, the pegasus’ cock was beginning to slip out from between his open legs. Thunderlane shivered a little at feeling the cool air hitting his exposed flesh; however, it seemed that the very scent of his musk was strong enough to make the pony behind the couch shudder audibly in response.

“Heh heh heh~” Thunderlane may have not known what was going on due to the heavy blindfold draped over his face, but he still sat back with a confident grin as he heard that mysterious figure coming in closer. “So… are you one of Rumble’s friends?”

Rumble wanted to grunt bitterly to his brother’s obliviousness, but he kept himself in check as he took a breath and muttered a high-pitched, “Mmmhmm~”

Thunderlane hummed as his smile widened, and he re-adjusted himself on the couch while his cock started to grow erect. Rumble nearly fell to the floor the instant he got a good look at that thick, veiny beast his brother had between his legs, which caused his knees to buckle involuntarily in response. Of course, that intoxicatingly masculine scent of sweat and musk only grew deeper as he saw his brother’s shaft grow longer inch by inch. But alas, Rumble was able to keep from muttering out anything too audible as he shuddered and exhaled through his open, drooling muzzle.

“Mmmmghhh…” Upon hearing that pony’s faint shiver, Thunderlane hummed happily before asking, “So, uhhh… this blindfold is for something kinky, right? Because if not, this might be awkward.”

“N-No, it--I-It is~” Rumble tried to reply sensually, even though he almost had a heart-attack when he said that first part in his natural voice. Fortunately, it didn’t seem like his brother was too stirred as he remained sprawled on the couch with that thick cock growing fully-erect, and towering daunthingly beneath his hefty gut. By the time Rumble walked around to the front of the couch to face Thunderlane directly, he had to keep his lips tightly shut while swallowing his excess drool. But alas, the younger pegasus sighed in elation as he stood with his wings twitching readily, and his admittedly below-average cock straining hard against the inside of his panties.

After needing a moment to breathe in weakly, Rumble added in a poorly-attempted girly voice. “J-Just, ummm… K-eep that blindfold on until I tell you, okay?~”

“Okay~” purred Thunderlane with a firm nod, and a notably hard twitch from his cock. By the time that stallionhood grew fully-erect, Rumble moaned out in a mixture of hunger and jealousy at the sight of it. Towering at an impressive ten inches in length (and a width nearly as dense as a rolling pin), the younger brother knew that Thunderlane’s was at least three times bigger than his own. Even though he didn’t mind his own petite-sized member, Rumble still bit his lip as he saw just how different his brother really was in comparison. Nevertheless, those racing thoughts weren’t enough to keep the young pegasus from getting onto his knees, and he kneeled in front of the couch as his eyes remained glued to that tempting cock.

Like some kind of magnetic pull, Rumble’s head slowly inched in towards that meaty stallionhood while his hooves rested atop of Thunderlane’s thighs. His older brother shivered with a strong exhale as he remained in place, ready to feel whatever it was this pony was wanting to try with him. Meanwhile, Rumble licked his lips upon seeing that thick cock so close to his face, with the musk heavy enough to taste on his tongue when he breathed in through his nostrils. His heart was racing fast enough to almost hurt his chest, but the girly-stallion knew better than to chicken out now; and with his lips glistening in a thick coat of that lipstick and his own saliva, Rumble closed his eyes with a weak moan before putting them to proper use.

The instant he wrapped his mouth around that meaty crown of Thunderlane’s cockhead, Rumble groaned out in pure elation when that dauntingly strong taste hit his drooling tongue. He instinctively swirled his tongue around that smooth, flat bulb of flesh to get it nice and wet, which caused Thunderlane’s hips to squirm with a shaky whinny in response. Rumble could feel how hard his brother’s shaft throbbed between his hungry lips, but his spine tingled when he felt a warm spurt of salty precum shoot inside of his mouth. The little pegasus almost coughed from the unexpected glob hitting the back of his throat, but he was able to instinctively swallow that load to make his fur stand on end. After all the years he spent fantasizing about blowing that stunning, caring stallion in his grasp, Rumble couldn’t have fathomed how much better the real thing felt and tasted in his muzzle.

“Ahhhhh… Ho… H-Holy shit~” Even though he clearly wasn’t expecting to get a blowjob that night (or for his brother to know somepony willing to give him one), Thunderlane wasn’t one to complain in the slightest as he savored each tenacious suckle of those slutty lips. His teeth gritted with a hearty groan while his head was leaned back against the back of the couch. He could feel that mysterious pony’s hooves resting on top of his legs, and he used his own to clutch the top of their head. Due to his blindfold, he couldn’t particularly tell who it was by just feeling their soft and tied-up mane; however, he did overhear a a cute-sounding coo that was muffled by their enthusiastic muzzle-work, as their lips began to slide down his shaft.

“Nnnnn~” Rumble’s heart skipped a beat the instant he felt his brother’s hooves rest on top of his head, prompting him to continue with his impromptu display he fantasized about for so long. Even though he knew that Thunderlane wasn’t aware it was him sucking on his fat, throbbing cock, the femmy pegasus wasn’t too fazed as he moaned from more of that stallionhood sliding into his mouth. He wasn’t sure how well his lipstick would hold up as his lips slid down that veiny shaft inch-by-inch; but with the elated-sounding whinnies he heard from above, Rumble’s ears twitched in delight as he kept going with vigour.

“Aaaahhh!!~” By the time Rumble was able to take at least a quarter of his brother’s cock inside of his drooling muzzle, Thunderlane’s grip on his head lessened enough for him to pull back and really get to work. Fortunately, the slender pony had spent more than a few nights with various guys to know how to work a cock to his utmost advantage. Because of that, Rumble seemed rather confident as he kept his lips tightly wrapped over his teeth, and began to slowly bob his head up and down that tremendously thick shaft. While he knew his muzzle wasn’t nearly big enough to take a lot of his brother’s length, he was content with just feeling all that forbidden cockmeat sliding in and out of his hungry maw. Meanwhile, his heart skipped a beat as he heard Thunderlane say with a pleased-sounding moan, “Mnnnnghhhh… You… You really wanted this, didn’t you?~”

Upon hearing that response, Rumble couldn’t help replying with a needy “Mmmhmm~” while continuing to suck on Thunderlane’s cock. Due to the overwhelming taste of the stallion’s musk plastering his tongue, and the multiple spurts of precum that kept shooting randomly to the back of his throat, Rumble didn’t care if his brother recognized his voice that time. In fact, part of him wanted to just reach up and pull that blindfold away, just so he could let Thunderlane know how much he wanted this. But instead, the feminine stallion was content with just sucking on more of that meaty length between his antsy groans, all while his hind-legs clenched together to counteract his painfully tensed erection.

“Ohhhhh man~” growled Thunderlane as he kept one of his hooves rested atop Rumble’s head, feeling just how eagerly that pony’s head was sliding back and forth across his cock. Meanwhile, his other foreleg rested along the back of the couch as he relaxed in such a pleasing position. With his breaths growing more rapid by the second, the burly pegasus knew that he was bound to cum sooner than later. Because of that, he let out a brief groan as he writhed his hips and tried to say, “H… Hey, Rumble! You wanna get in on this?~”

Rumble almost gasped in a panic the instant he heard his brother call for him by name. However, he was able to breathe out in relief through his nostrils after hearing that second part that was asked so casually. Even when he was getting blown by some random pony he couldn’t see, Thunderlane was still generous enough to offer some pleasure for his younger brother as well. Rumble wanted to chuckle at such a blissfully unaware statement, but it was thoughtful requests like that which made him love Thunderlane so much more than just a brother.

With his heart pounding relentlessly in his chest, and his little cock throbbing hard within his panties, Rumble was too pent-up to really think over what he did next. Since his mind was clouded in a dangerous mixture of excitement and lust, the femmy pegasus pulled his mouth back with a wet schlick, and took a breath before speaking in his regular voice. “I already am, Bro~”

Rumble didn’t really pause to see his brother’s reaction to that, and went right back to sucking on his cock with a hungry moan. Meanwhile, Thunderlane’s brows rose high enough to be seen above the rim of his blindfold, and he froze in place while processing what was actually happening. “Uhhh… W-What?” he asked in a much more serious-sounding tone. But despite how freaked-out the husky pegasus looked as he laid back with his muzzle slightly agape, his cock still throbbed hard inside of the newly-revealed mouth of his younger brother’s. He wasn’t sure if it was because of the amazing blowjob itself, or the added shock of knowing who it was that contributed more blood-flow from his jolted heart, but Thunderlane’s body twitched involuntarily as he felt himself reaching his peak by utter surprise. “AAAHHH!! R… R-RUMBLE?!”

“Nnnnnnghh!~” Upon feeling just how hard Thunderlane’s shaft twitched between his hungry lips, Rumble knew he couldn’t just suck him off to make his fantasy feel complete. Instead, the pegasus pulled his mouth off of his brother’s cock again, and reached up to take off that blindfold. Thunderlane winced from the sudden light hitting his eyes, but yelped the instant he saw that it really was his brother kneeled in front of his cock. Even though he could see how freaked-out his older brother looked above him, Rumble just carried a sly and lustrous grin as he stared back up at him, and used a hoof to stroke that shaft vigorously. “Ahhhh… Oh, Thunderlane~”

The Wonderbolt had his mouth agape as he remained motionless on the couch, unable to pull away while his nerves continuously twitched from his younger brother’s touch. Meanwhile, Rumble groaned with an eager smirk while licking his lips sensually up at Thunderlane, knowing how doubtful it would be for his big brother to stop him now. That guess proved to be especially truthful the instant Rumble opened his mouth wide, and continued tugging on Thunderlane’s throbbing shaft while the head was pointed directly at his face. As if his promiscuous attire and appearance wasn’t tantalizing enough to make Thunderlane freeze in awe, Rumble made sure to stick his tongue out rather lewdly while anticipating his brother’s cumshot.

“GNNNGHHH!!” Thunderlane tried to resist, but his gritted teeth could only counteract so much while his cock pulsated hard in his brother’s grip. Not to mention, the slender pegasus looked unbelievably hot with all that slutty makeup on his face, and his hair tied up in a ponytail like the Wonderbolt preferred. Thunderlane likely would’ve approved of his brother’s choice of attire as well, but it was near impossible to look away from that sexy face waiting for a proper bukkake. Blood relation or not, the older pegasus could only groan painfully with his hooves curling up as he inevitably succumbed to his building orgasm. “Ahhhh! I’m… I’m gonna!! I’M GONNA!!~”

Rumble closed his eyes as he moaned out in the sluttiest tone possible, and gave that pulsating cockhead one last lick of his tongue to really set Thunderlane off. The sight of such a thing overrode any of the Wonderbolt’s morals as he convulsed on the couch, and cried out while unloading a massive volley of cum directly towards his brother’s face. His heavy balls rode up into him as he felt his climax sweep over him, and he could only watch as Rumble experienced the result of one of his strongest orgasms he ever felt.

The first couple strands of Thunderlane’s cum shot directly into Rumble’s waiting mouth, which caused the younger pegasus to shudder with his eyes rolling back. Of course, it didn’t take long for the Wonderbolt’s thick, virile load to fill Rumble’s muzzle to the point where he had to close his mouth. Just as he did so to swallow with a deep, audible gulp, the femmy stallion was rewarded with several more hefty ropes of cum that landed all across his face and mane. Multiple strings of his brother’s milky-white, gooey strands hung obscenely across his cheeks and muzzle, with one particular strand clinging onto his ponytail to really add to his look. Just as Thunderlane threw his head back with a moan, and the last of his spurts shot out onto Rumble’s chest weakly, the younger pony shuddered with an elated smile as he swallowed the last of his brother’s load.

“Ahhhhhhh…~” Rumble waited a moment before re-opening his muzzle, showing that his mouth was completely empty after swallowing the mouthful Thunderlane shot into it. Even though his face was still drizzled with a lot more of his brother’s cum, the pegasus seemed rather content as he looked up at him and tried to breathe steadily. “You… You okay, bro?~”

As the seconds passed between them in silence, with Thunderlane panting heavily while coming down from his climax, Rumble’s muzzle began to skew a little in worry. Given how quickly everything transpired, he half-expected for his brother to lash out at him the instant he grew flaccid again. He may have still been unbelievably horny while seated before Thunderlane’s cock, but he was prepared to rush out of the living room if his brother even looked at him angrily. Fortunately, by the time the Wonderbolt was able to look back down at Rumble with his eyes opened, the only thing that could be seen was a vacantly stunned expression on his face.

Thunderlane blinked a couple times as he gawked at his sissified, bukkaked brother in a moment of deafening silence. Rumble wasn’t sure what was going to happen next, but he tried to remain positive as he gave a weak smile up to him while blushing. He could see his older brother’s eyes slowly glance up and down his dolled-up form, now getting a proper look at how much work the slender pegasus went through for the sake of this moment. Thunderlane began to blush as well, but it was unclear for what reason until he opened his mouth. “Y… You… You’re, ummm…”

After pausing for a second to gulp somewhat-nervously, Thunderlane exhaled and said in a blunt tone, “You’re giving me the weirdest boner right now.”

Upon hearing such a statement (and making a quick glance down at his brother’s semi-flaccid member), Rumble couldn’t help giggling with a hoof over his splattered face. “Hehehehe… W-Well, I… I wanted this to happen for a while, I guess~”

Thunderlane still looked warily wide-eyed, but he still nodded his head faintly in response. “Yeah, I… I can see that…”

After another moment of silence, Rumble’s smile lessened a little as he huffed through his nostrils. He bit his lip before looking away from him and saying, “I… I’m sorry if this freaks you out, okay? I just… I’ve wanted this for a really long time, but I… I was worried how you’d react if I just asked you upfront…”

Thunderlane’s blush deepened immensely as he remained on the couch. His muzzle pursed together the tiniest bit, and his face showed a brief look of guilt upon seeing how meek Rumble appeared during that apology. Meanwhile, the younger pegasus took a breath before adding. “If… If you’re mad at me, or… if you don’t want to do anything else with me, I completely understand. I just… I really wanted you to know how much I wanted you, and… a-and how much I love you…”

That added statement made Thunderlane’s ears droop down, almost as if he was hurt by hearing such a thing. Despite how much his head was still reeling, the older stallion quickly replied with a sincere, “H-Hey, hey, come on! Rumble, I’m not, like… I’m not mad at you! I’m just, uhhhh… I’m still processing all of this, that’s all…”

Thunderlane knew that response was weak at best, but it seemed to be enough to make Rumble glance up at him with a more hopeful-looking expression. After taking another breath, Thunderlane scratched the back of his mohawk with a hoof and asked, “You… You really, like… want me, want me? I mean… I’m not judging if you are, I just… You know~” Thunderlane didn’t want to call himself fat (mostly since he knew how easily he could drop the pounds before Wonderbolt season came back up), but he still motioned down to his hairy, pudgy build to emphasize his disbelief towards his brother.

Luckily, Rumble just scoffed and rolled his eyes. “Oh, please~” he replied as his own blush deepened in slight embarrassment. “I kinda… Like seeing you with that kind of body, bro. It… It’s really nice on you~”

Despite his confusion, Thunderlane could tell that his younger brother wasn’t lying or exaggerating about that claim. Nevertheless, he still huffed with a smirk and asked teasingly, “Oh, what? You got a thing for guys with Dad bods too?”

“Y-Yeah!” chirped Rumble almost instantly, which caused an even deeper blush to practically explode across his face. After taking a second to cringe at his readiness to that answer, he quickly blurted before his brother could laugh, “B-But I just mean Dad-bods, okay?! I’m not… I’m not saying OUR Dad was hot or anything!”

“Pbbt! I hope not,” said Thunderlane with an honest tilt of his head. “He wasn’t exactly a looker, from what I remember of him.”

“Mmmhmm…” Rumble’s muzzle pursed briefly, not wanting to think too hard about their Dad despite what he was doing right now with his brother. Since he was wanting to continue their impromptu session, Rumble took a quick breath before saying insistently, “But… But honestly dude, you’re like… reeeeaaallllly hot~”

Thunderlane tried to chuckly slyly back down at him, but it came out rather weakly while seeing how antsy his brother was looking. “Well, uhhh… I gotta admit, you look pretty damn cute right now too~”

Rumble could sense his older brother’s apprehension, but he still beamed proudly as he smiled back at him. He also squirmed with a dangerously adorable blush before turning his head away bashfully. “W-Well, I… I’m glad you finally see that…”

Even with how scantily clad he was dressed, and how drizzled he was in his brother’s cum, Thunderlane could see that Rumble was shy about admitting that last statement. Of course, given how much detail he placed into his whole getup, the Wonderbolt didn’t need another orgasm to see that Rumble likely wanted him sexually for a long time. The fact that it was his younger brother was still gnawing into his conscience bitterly, but any feelings of remorse or disgust didn’t seem to manifest as he let the seconds between them pass. In fact, Thunderlane was able to take in the sight of Rumble in such a lustrous new light, and bite his bottom lip with a feeling of guilty arousal.

Rumble shivered the instant he saw that action his brother inadvertently made. “Mmmmghh… S-So, I… I take it you really like what you see, huh?~”

After gulping nervously, Thunderlane couldn’t ignore that question when he saw the sultry stare his brother was giving him. His cock was still trying to recover from that blowjob he received, but he still had the strength to nod his head honestly to Rumble.

“Mmmmmmm…~” With that, Rumble rose up from between Thunderlane’s legs so he could stand on all fours. With his brother still staring at him in shamefully aroused awe, the slender pegasus decided to up the ante as he brought his hoof up, and swiped a hefty glob of Thunderlane’s cum from the bridge of his muzzle. Then while keeping his eyes locked on the blushed Wonderbolt, Rumble hummed in a deeply enticed moan as he dragged his tongue across his hoof slowly. His body could be seen shivering as he lapped up that thick dollop of his brother’s cum, and let it linger on his tongue while it was stuck out for Thunderlane to see.

Then with a pert smile and a narrowing of his eyes, Rumble brought that cum-slathered tongue into his mouth before making a strong, audible gulp.

Rumble may have been his brother, but fuck if that wasn’t hot as Tartarus. Thunderlane shuddered immensely hard on the couch upon seeing such a flauntingly tempting display, and his cock twitched hard enough to become at least three-quarters erect in an instant. Of course, since Rumble’s eyes were focused enough on that part of his brother’s body, he saw it as an unspoken prompt to keep going. The feminine pony chuckled with a determined stare as he looked back up at Thunderlane’s face. “So, big bro… You wanna see what else I have as a surprise for you?~”

The Wonderbolt’s blush may have been deep enough to cover his dark-grey coat, but his body wasn’t frozen enough to keep him from nodding his head. Nor was he too overwhelmed to keep from replying with a firm exhale. “Y… Yeah.”

Rumble’s grin grew wickedly wide, and he quickly turned himself around to brace his front hooves against the coffee table. Meanwhile, his backside was pointed directly at his brother while his tail swung teasingly across his pantied rump. Since his face was less than a couple feet from that deceptively thick rear, Thunderlane’s eyes widened as he shuddered through his open muzzle. With each rehearsed movement his little brother made with the tempting sways of his hips, the gruff pegasus could see just how much that booty jiggled from even the slightest movement.

Without even thinking, Thunderlane let out a weak and trembling moan as he reached out and grabbed a plump cheek in both hooves. Rumble yelped out with a slutty moan, and grinned with a bit lip at feeling his brother’s tight grip on him. He knew that he spent far too long just wishing for that stud of a stallion to realize how he felt, but to actually feel him accept those feelings by holding him so dominantly made his heart flutter in pure bliss. He wanted nothing more than to just pull his panties down, and to beg for Thunderlane to plow him right then and there. But alas, he knew it was better for his brother to take his time, and to marvel at his body for everything it was worth.

Meanwhile, Thunderlane had to groan through gritted teeth while scanning that curvy, twitching body his younger brother possessed. His hooves dug into that soft, supple flesh like it was a firm pillow; fortunately, it only elicited the cutest moans from Rumble as he let the stallion claim him as his own. Those pink panties hugged every curvature and dimple across his meaty cheeks, which looked just as tantalizing to Thunderlane as most of the mares he bagged during Wonderbolt season. Of course, just as he glanced at the smoother region between Rumble’s plump cheeks, it was then that Thunderlane noticed the ‘surprise’ his brother had in store for him. It may have been nothing more than a small, rectangular bulge that emerged through those panties just beneath Rumble’s tail, but the implication of what it was still made Thunderlane shudder in guilty delight.

Without any warning, the stallion yanked down Rumble’s panties to make him squeak out a little. Meanwhile, Thunderlane grunted with a bit lip as he marveled at that thick, black rubber plug that covered Rumble’s lubed and petite tailhole. Even though the femmy pegasus’ cheeks looked even juicier with the panties removed, the Wonderbolt’s sights were locked onto that little nub between them. He could see that the plug was twitching and pushing inward with each twitch of Rumble’s body, indicating that his hole seemed eager to suck up the rest of whatever was slipped inside of him. With his mind becoming clouded in lustful intrigue once more, Thunderlane shuddered a little before asking, “So, little bro… I take it that this is the surprise for me?~”

“Nnnnnnghhhh… Mmmhmm~” hummed the slender pegasus as he shivered and lowered himself even more. Now in a fully presented stance while leaned against the table, Rumble had to clench his eyes shut while savoring the nerve-wracking feelings sweeping across his body. “I… I wanted you to see how… H-How stretched out I am for you~”

“Ohhhhhh, man~” Thunderlane licked his lips as he reached in with a hoof, and got a good hold of that plug to make his brother tense up briefly. While Rumble moaned out and quivered from the added pressure of that hoof against his toy, he heard him say with an impressed tone of voice, “I gotta say… I can’t say I ever encountered a mare slutty enough to already have a plug in her for me~”

Rumble was teetering on the brink already, and could feel his petite cock leaking a steady dribble of precum onto the living room carpet. However, he was still randy enough to look back at his brother with a cheeky grin and reply shakily, “W-Well, uhhh… There’s two things you should know. One… that isn’t just a plug I have in me~”

While Thunderlane’s brows rose in surprise upon hearing that first part, Rumble’s smile widened devilishly as he added his second point as sultry of a tone as possible. “And T-Two… I… I’m pretty sure there aren’t many mares who’ll be as good of a slut for you as me~”

Thunderlane almost let go of that plug as he shivered in arousal to such a reply. Luckily, his grip remained as hard and relenting as his cock, which was now back to its full length and twitching between his legs. As he began to pull back on that plug, taking his sweet time so he could hear his brother’s enticingly deep moans, Thunderlane smirked with a chuckle as he asked, “Oh, really Bro? Is that what this is all about?~ I gotta say, I wouldn’t have expected you to be such a dirty little colt…”

The tension of that toy grew harder the more he pulled, but Thunderlane stayed diligent as he heard how heartily his brother groaned from the sensation. He glanced down to see that plug pulling away, revealing Rumble’s perky pink pucker that was expanding while the base was still hugging it. His eyes widened as he saw how much that hole was beginning to stretch out, undoubtedly covering up something rather thick that the pegasus inserted earlier. Meanwhile, the slutty stallion cried out in shaky elation and said, “Y-Yes!!~ I… I’m such a… A diirrrrrrrty little slut~”

Before Thunderlane could even grin to such a lustfully-said reply, part of that toy inside of Rumble finally came out with a wet pop. The burly stallion looked down to see what was connected to that base, which was revealed to be a rubber orb as thick as a tennis ball. However, that ball also had a thick latex string connected to the top, as the other end lead towards the pegasus’ hole. Tunderlane’s jaw dropped before he shuddered, realizing that his brother actually had anal beads inside of him for this occasion. Of course, he also noticed that something was inscribed in white lettering on the other side of that rubber orb; after turning it around, Thunderlane smirked upon reading what was written on his brother’s surprise gift for him:

Daddy’s Little Colt

“Ooooohhhh~” Thunderlane grinned ear-to-ear, and tilted his head as he glanced down at his brother’s blushed face. “Well, I guess that explains why you said you liked Dad bods so quickly, huh?~”

Despite his eager grin, Rumble’s head still lowered a little in bashfulness. “W-Well, ummm… Kinda, yeah…”

A low, lumbering chuckle came out of Thunderlane’s smirked muzzle with enough vibrato to make his beer-belly jiggle beneath his barrel. And with the way his cock was repeatedly slapping against that gut like the beating of a drum, it was clear the the older pegasus was getting into the role as he leaned down, and got himself close to Rumble’s ear. “If you don’t mind me asking,” he whispered with a domineering sneer while licking his lips, “does that toy mean you wanna call me something… special~?”

Rumble shuddered with a bit lip upon feeling his brother’s hot breath so close to his silver fur. Even though he was more than enthusiastic enough to nod with vigor, the femmy pegasus kept himself timid while Thunderlane was standing over him. His heart was racing in dire need for that burly stud to just breed him right then and there, but he let out a faint and shaky exhale before replying, “Y… Y-Yes, umm… Daddy~”

If Thunderlane was told an hour before this moment what he’d end up doing, he’d likely freak the fuck out and run off elsewhere. But with his saliva-coated cock now rock-hard and eager to deliver another load for his slutty brother, the Wonderbolt couldn’t stop grinning as he went back to playing with Rumble’s “gift” for him. “Mmmmnnnghhhh… Oh, man this is gonna be fun~”

Thunderlane was sick of waiting, and quickly took a hold of that latex string that connected the base of Rumble’s toy to the rest inside of him. The instant he began to pull on the thin and sturdy line, his brother moaned out with his head reeled back and his eyes clenched shut. Meanwhile, Thunderlane groaned through his clenched muzzle upon seeing another black, thick orb begin to emerge from inside Rumble’s twitching hole. That pink, petite pucker proved to be quite well-used as that second ball started to sink out of Rumble’s yawning exit, exposing that glistening black rubber enveloped within the ring of supple flesh. Thunderlane expected that ball to be at least a little smaller than the first, but Rumble’s little hole kept stretching out as more of that toy was exposed and causing the slut to moan loudly. Just as Thunderlane thought it was going to end up being bigger than the first, an identically-sized ball came out of his brother’s hole with a wet pop.

“AHHHH!!~ Mmmmmnnnnnffffff~” Rumble was trembling like mad while perched on the coffee table, but kept an elated grin on his face as he felt Thunderlane grab the next section of string. “Aaaahhhh… Kee… K-Keep going, Daddy~ I… I really need your cock in me instead~”

“Well, I certainly like the sound of that idea~” purred the Wonderbolt as he kept going, taking his sweet time as he continued to pull out each orb at a teasingly slow pace. Rumble’s legs were twitching as hard as his little cock from each stretching of his needy hole, but he couldn’t have cared less as he heard his brother’s enticed groans between each pop. Meanwhile, Thunderlane was growing increasingly horny as he pulled out bead after bead, each one only slightly smaller than the last while keeping his brother on edge. By the time that reddened hole was feeling tremendously loose from the lessening tension of the string, Thunderlane saw that last thick, golf-ball sized orb pop out effortlessly from Rumble’s waiting entrance.

“Aaaaahhhhhh…~” Rumble sighed in sweet, sweet relief at feeling that last bead exit his hole, leaving him feeling tremendously loose and needy for something better to fill him up. As he let out a long, rumbling groan that resembled a hungry predator’s growl, his eyes were narrowed back at Thunderlane alongside a very wide grin. As he kept his tail flagged up diligently, Rumble braced himself as he saw that hungry smirk his brother possessed. “Mmmmmm… Please, Daddy~ I’ve wanted this for so long… I… I want you to breed my slutty little hole, PLEASE!~”

If Thunderlane wasn’t already past the point of return from Rumble’s appearance, his blowjob, or that daunting toy, that lustfully-spoken plea would’ve done it in a heartbeat. The older pony’s hooves gripped those thick, supple cheeks tightly enough to make Rumble yelp weakly in response. The stallion shuddered with a widening grin as he saw just how soft and juicy his brother’s ass felt, and he didn’t hesitate as he brought his hips closer to that tempting rump. Thunderlane’s thick, meaty cock was pointed directly at his brother’s puckering hole, close enough for Rumble to feel the heat coming off of it. The slutty pegasus’ body was beyond ready, and he could only tense himself up in pure anticipation as he awaited for his brother to properly mount--

“WHOOOOP!”

Thunderlane’s chest came down to rest atop Rumble’s back, and his hooves tightly wrapped around his brother’s slender barrel. However, instead of just plowing into him like the femmy pony wanted, Thunderlane picked Rumble up like he weighed nothing at all. As the younger brother let out a surprised yelp as he was lifted off the ground, Thunderlane effortlessly spun him around so he could be planted on the couch. Before he could even realize what was going on, Rumble found himself laid on his back while his older brother was perched over him.

“Th… Thunderlane?” he asked in a meek and confused tone, unsure of what his brother was trying to do. Meanwhile, Thunderlane carried a much warmer-looking smile as he stared down at him lovingly.

“What?” asked the Wonderbolt with a small shrug of his shoulders. “You really think when you get yourself dressed like that, I’d wanna fuck you without getting a good look at your face?~”

Rumble was frozen for a moment in stunned silence, having never expected for his brother to say something that sweet or meaningful. However, it didn’t take long for Rumble to blush with a trembling smile, and try not to cry from Thunderlane’s touching response. “You… You wanna look at me?” he said in a weak-sounding creak.

“Well, it seems like you wanted that reaction, didn’t you?~” asked Thunderlane in a cheekier tone of voice. “Besides, I prefer dolphin-style anyway~”

Even though he was still elated from Thunderlane’s sentiment, hearing that term used non-ironically made Rumble giggle a little. Thunderlane’s smile grew warmer upon seeing that reaction, undoubtedly loving how cute his brother looked in such a position. As he got himself better situated on top of him, the Wonderbolt couldn’t help marveling at the rest of Rumble’s body as he said, “You know… I think I can get used to having somepony like…”

The instant Thunderlane’s golden eyes peered down between his brother’s legs, his brows rose in surprise at seeing what Rumble was packing. The younger pony blushed profusely when he saw that wide-eyed reaction, causing him to bite his lip and squirm a little while on his back. Meanwhile, the femmy pegasus’ petite little stallionhood twitched readily while standing at a miniscule three inches in length, accompanied by a pair of balls that were no bigger than a couple of marbles. Rumble may have already known that he was below average, but he looked absolutely puny compared to Thunderlane’s rigid cock.

Of course, judging by the meek smile on his blushing face, it was doubtful that Rumble saw that as a bad thing.

Thunderlane remained silent for a couple seconds, but finally responded to that meager member as he tried to cover his mouth. “Pbbt~”

Rumble squirmed a little more at hearing Thunderlane struggling not to laugh, and blushed even deeper as his felt his little cock throb in approval. Meanwhile, his brother quickly blurted a sincere, “Sorry, sorry! Just, ummm… I wasn’t expecting that. I’m not making fun, I swear.”

Even though he appreciated that sentiment, Rumble shrugged his shoulders the slightest bit before he replied sheepishly. “W-Well, ummm… I… I don’t mind, Daddy~”

Thunderlane’s eyes widened even more at hearing such a thing, and his eyes looked up from that nub to see the timid expression his brother was giving him. “You… You can poke fun if you want~”

That assurance was even more surprising for Thunderlane to hear. However, he couldn’t necessarily complain when he saw how ready his brother looked to be given a real cock. While the idea of actually being encouraged to mock Rumble’s equipment seemed off-putting, Thunderlane couldn’t necessarily complain when he was about to fuck his own brother. So after taking a quick breath, the Wonderbolt shrugged his shoulders in acceptance and got himself positioned between Rumble’s legs. “Well, I guess I’ll take your word for it…”

Just as Thunderlane got himself on a kneeled position on the couch with his cock pointed at his brother’s plump rear, he huffed before finishing his statement with a coy-looking grin. “... I mean, given what you have, it seems like you need a cock as big as mine, huh?~”

Rumble giggled with a blush as red as a cherry tomato, and meekly nodded while smiling up at his cocky brother. “Y-Yeah~ I… I really need a proper stallion like you, Daddy~”

Since his hole was already adequately lubed and stretched-out by his toy (not to mention the thick coating of his saliva all over Thunderlane’s stallionhood), Rumble saw no reason to hesitate as he spread his hind-legs apart to give easier access. Due to his positioning, his measly nub of a penis continued to twitch antsily for his brother to see. Despite its size, a decent amount of precum had spurted out to leave a noticeably large puddle of matted fur across his lower stomach. Fortunately, Rumble wasn’t the only pegasus to be leaking as Thunderlane’s cock continued to throb, and was already oozing more pre so soon after his first orgasm. His flat, crowned cockhead was glistening with his sticky fluids, ensuring that the Wonderbolt wouldn’t have much trouble with Rumble’s puckering tailhole.

“Mmmnnnffffff~” Thunderlane and Rumble both let out strained moans the instant the older stallion leaned his hips inward, and prodded the outside of that waiting hole. Rumble’s eyes rolled back as he trembled underneath him, and carried a blissful look on his face while gripping the fabric of the couch with both hooves. Meanwhile, Thunderlane shivered with a grin alongside his gritted teeth, and kept his eyes pinned on that stunning pony in his grasp. Even though he knew he couldn’t blame himself for only seeing Rumble as a brother until that night, he still felt overwhelmingly daft for not noticing how tantalizing he looked until now. With the way he was all dolled-up to accentuate his curves, and how adorable he appeared while blushing profusely, Rumble looked absolutely perfect in his brother’s eyes.

“Oh… Oh man,” Thunderlane said with a weak exhale as he pushed, not needing much pressure to pop his meaty cockhead inside of the younger pegasus. As Rumble moaned out and tried to clench around that thick appendage, his brother continued to speak while looking down at him with a shake of his head. “I swear, I… I should’ve seen how you looked sooner, bro. You… You’re really fuckin’ hot like this~”

Even though his face was tensed-up from the intense stretching he was feeling from Thunderlane’s cock, Rumble still smiled lovingly up at his brother and nodded shakily. “Y-Yeah~ I… I’ve wanted you for so long, Thunderlane~”

“Well, little bro…” Thunderlane took his time as he pushed himself inside of Rumble, and used that pause in his words to make sure the entirety of his head was able to slip inside. The younger stallion let out a brief groan as he felt that meaty head go in, which Thunderlane could hear with a wet schlick. As that thick crown began to push its way deeper inside of Rumble, eliciting even more squirms from the pony due to it brushing up against every inch so intensely, Thunderlane was able to lean his head down to get his muzzle close to his brother’s. “... You have me now~”

Upon hearing that genuine whisper from the stallion working his way inside of him, Rumble’s heart jumped up to his throat. He looked up at him while wide-eyed, and felt his eyes start to tear up when he saw the sincerity in Thunderlane’s smile. But before he could even think about crying tears of joy, Rumble was taken by surprise as his brother leaned in to press his lips against his. As their muzzles connected, Thunderlane continued to push more of his length inside while feeling how much his brother was trembling in his grasp.

Fortunately, it didn’t take long for Rumble to reciprocate that kiss. Even with how invigorating it felt to finally experience that first bout of penetration from the studly stallion, Rumble was quick to throw his hooves up to wrap around the back of Thunderlane’s neck. His eyes clenched tightly shut, and he began to passionately kiss his brother with undying passion. As inch after inch of that rigid stallionhood slid its way inside of the femmy pegasus, his moans came out rather muffled as he sank deeper into pleasure, and made out with Thunderlane with growing intensity. His mouth may have tasted strongly of his brother’s cum, but it seemed like Thunderlane didn’t mind his own flavor too much as their kiss grew more intense by the second.

Tongues soon began to mesh and slide against one another, and their muzzles started to grow wet due to the saliva the two they were exchanging. Between their connected bodies, Rumble’s tiny cock continued to throb and spurt out more pre, which smeared across both of them to leave patches of matted fur across their stomachs. Due to the growing passion and lust building up between the brothers, Rumble was too lost in pleasure to realize how much of Thunderlane’s cock was pushing inside of him. It wasn’t until he felt that thick, daunting medial ridge that the pegasus felt how deep his brother had gotten. When he broke away from the kiss briefly enough to look down, he gasped in shock upon seeing the faint, but very noticeable bulge of Thunderlane’s cockhead prodding from just above his waist.

“WHOA! Ho… Holy fuck!~”

Meanwhile, Thunderlane just chuckled in delight upon seeing his brother’s flustered reaction. Judging by the look on his face, it seemed that this wasn’t the first time he saw that kind of look from a pony he was fucking. “Heh heh heh, I know right? Honestly, I think that bulge is a little bigger than anything you have~”

Rumble’s muzzle wrinkled upon hearing such a crass statement, but the humiliation made his heart race enough to make him smile while looking up and blushing in response. “W-Well, ummm… Yeah, probably…~”

“Mmmhmm~” hummed the older pony with a teasing smile alongside his nod. “Honestly, though? I’m pretty sure I’ve been with a few girls with clits bigger than that thing~”

Rumble shuddered with a weak-sounding moan in response, and he had to bite his lip to keep from cumming while Thunderlane’s cock was buried inside of him. “Mmnnghh~ Y-Yeah, I’m sure that’s true. Hehehehehe~”

After taking a quick breath, Rumble moaned out when he brought a hoof down to press against that thick bulge Thunderlane’s cock made inside of his torso. While his brother shivered from feeling that additional tension, Rumble’s eyes rolled back upon feeling how much cock was inside of him. “Oh goddess, I… I can’t keep waiting anymore!~ Pl… Please Thunderlane, fuck me!!~ FUCK ME RIGHT NOW!!!~”

A strong breath of hot air shot out through Thunderlane’s nostrils like an enraged bull, and the first motion of his hips caused his brother to gasp out with a shocked expression. The Wonderbolt pulled his hips back from his brother’s, causing his medial ridge to emerge through that needy tailhole with a wet pop. Fortunately, the stallion didn’t do the same with his cockhead when he pulled most of his length out, and made sure he was still ‘inside’ of Rumble in anticipation for his next move. Of course, judging by how hard Rumble’s body was twitching beneath his raised fur, it was doubtful that Thunderlane was nearly as excited for his incoming thrust as his brother was. The little pegasus’ hole was continuously clenching around that crowned head in dire need, and he was writhing on the couch as he endured that lingering feeling of emptiness he so desperately needed to end.

During Rumble’s trembling cries for that first hard thrust to fill him up again, Thunderlane exhaled quite eagerly as he savored the tightness of his brother’s hole. His pause only lasted a couple seconds, but it was enough to leave Rumble teetering just at the brink of desperation before hearing him say, “I… r-reaaallllly hope you’re ready for this!~”

Rumble wanted nothing more than to scream out that he was ready for that cock years ago. However, the only thing to come out of the slutty pegasus’ mouth was an Earth-shattering cry the instant he felt Thunderlane slam his hips into that plump and waiting rear. The younger pony’s nerves nearly overloaded as he felt that thick and veiny beast ram inside of him, delivering that much-needed filling he was craving for so long. Even though the burning pain of that first thrust felt more intense than he could’ve ever imagined, Rumble’s heart melted into pure ecstasy the moment he felt his brother’s shaft slide in hard against his prostate. His little cock was throbbing at the brink of orgasm already, but the slut was gonna be damned if he wasn’t going to make Thunderlane cum first.

Fortunately, the older stallion seemed more than eager to fulfill that unspoken wish, and barely hesitated before pulling his length back to repeat the process. The second time around, Rumble’s piercing cries of pleasure were enough to make Thunderlane know he could move at a faster pace. Because of that, the burly stallion paused for only a second when just his cockhead was inside of his brother’s quivering body. With his second thrust inside of Rumble, their bodies collided with enough force to not only make the younger pegasus’ thick cheeks jiggle, but to also make Thunderlane’s plump balls slap lewdly against the base of his tail.

Of course, neither of them were able to appreciate those meaty slaps of flesh due to Rumble’s overwhelming cries of bliss which enveloped the living room. Fortunately, that was exactly what Thunderlane wanted to hear as he went into a primal, rapid rhythm with his hips against that thick ass. Before Rumble could even get another breath out, he was left continuously moaning as he felt his brother continue at a regular pace. As soon as those pauses in Thunderlane’s motions stopped, and that massive cock continued to slide in and out with an unrelenting amount of force, the femmy pony was completely lost in the moment as his body laid paralyzed in euphoria.

Rumble had no idea how long his brother went for, mostly since the constant stimulation to his prostate left his mind in a heavy cloud of lust and desire. Meanwhile, Thunderlane was constantly groaning through gritted teeth as he grew hotter with each heavy thrust, and felt his own body sink into the passion of the moment like quicksand. His cock slid in and out of Rumble’s tight hole repeatedly to keep him on edge, and constantly kept the slut moaning from unending titillation. The hefty smacks from Thunderlane’s hips and balls continued as he pounded his brother with all of his might, showing off that notorious Wonderbolt strength and stamina despite his bulky build. If Rumble was in a clearer state of mind, he would’ve adored seeing the older pegasus’ gut and love-handles jiggling with each thrust he made into him; but considering how hard his little cock was throbbing, the femmy pony knew he couldn’t have asked for a better first time with the stallion he loved so much.

Especially when he felt Thunderlane’s cock start to throb distinctly hard inside of him as well.

“Nnnnffffff!!~” Even with how amazing his brother looked underneath him, Thunderlane’s eyes clenched shut as he felt himself reaching the peak for his second orgasm. His hips bore down even harder against Rumble’s ass while climbing closer to climax, and his thrusts became more erratic. “Rumble! I… I’m gon… I’m gonna…”

The younger stallion knew exactly what was going to happen, and gasped with a heavy blush at the idea of Thunderlane giving him exactly what he yearned for so long. His breaths may have been coming out faintly between his merciless moans, but Rumble used whatever strength he had left to belt out passionately, “D-DADDY! Don… Don’t… D-Don’t you DARE pull out!!~”

That needy cry made Thunderlane’s cock pulsate even harder inside of the slender pegasus, which elicited even stronger groans of pleasure from the slut upon feeling it against his prostate. His little cock was leaking precum profusely, and it took everything in him not to erupt right then and there as he heard his brother say, “I… I won’t do that, bro! I… I swear I’m gonna fuckin’ BREED ya!!~”

“Y… YYYEESSSS!!!~” Unable to hold back his elation, Rumble’s back arched upward as he felt those last few thrusts being plowed into his hungry hole. He could hear his Daddy’s unrelenting groans as he reached his climax, and felt his much that massive cockhead was swelling up inside of him. Even though he knew it was impossible (unless a spell or potion existed somewhere), part of Rumble’s conscience wished that he really could get bred by his brother as his mind melded into pure debauchery. But alas, despite how much the idea made his nerves tingle endlessly, thoughts as lewd as those had to wait as he took a deep breath. “I… I LOVE YOU, THUNDERLANE!!!~”

“I… I LOVE YOU TOOOOOO!!!~” With one last thrust, Thunderlane drove his cock as deep into Rumble as he could with that last inflected word. His whole body spasmed as he felt his cock throb strongly inside of the pony, unloading a massive volley of his thick, virile seed into his brother’s deepest depths. Rumble’s mouth hung open as he cried out passionately, letting the warmth of his Daddy’s seed flooding within him be the green-light to shoot his load as well. However, just as his tiny cock was about to spurt out its meager load, Rumble’s mouth was covered by Thunderlane’s as he kissed him deeply.

The brothers’ shared orgasm lasted far longer than either of them expected, mostly due to how long the two kissed during their intimate moment. Thunderlane’s balls rode up repeatedly as multiple ropes of seed unloaded inside of his brother, which only added to that thick bulge in his torso that was already evident by the Wonderbolt’s stallionhood alone. The rich, overwhelming volume of cum expanded out inside of the pegasus, which caused Rumble to squirm with a muffled moan while continuing to kiss Thunderlane lovingly. By the time the older stallion was spent from his second orgasm, Rumble’s stomach was swollen with enough cum to make him look legitimately pregnant. And once again, the contrast between the two ponies was even more evident when the aftermath of the little brother’s climax could be seen between them; even with how much precum he managed to leak out, Rumble’s cumshot amounted to two or three measly spurts that barely reached to the top of his stomach.

But alas, Rumble couldn’t have asked for a better conclusion as he kept his lips pressed against his brother’s, and trembled from the random twitches his body made in response to such a fur-raisingly hot finale. With his nerves frayed from that passionate moment, and his body completely filled with Thunderlane and his seed, the little pegasus couldn’t imagine a better ending in comparison to his wildest fantasies. As he laid panting in a post-orgasmic stupor, Rumble was eternally grateful that Thunderlane remained by his side while laying atop him on the couch. With his cock still buried deep inside of him, the gruff Wonderbolt held his brother with a blissful smile while the two savored the afterglow of such a taboo experience.

“Mmmmmm… I… I can’t thank you enough,” whispered Rumble as he closed his eyes and nuzzled his brother’s chest weakly. “Th… Thank you so much…”

“It’s alright, bro,” Thunderlane replied in a faint, but still assuring whisper of his own. “I’m just glad I was able to do this.”

“Mmmmm… M-Me too…”

Several minutes of silence passed as the two rested together in the living room, with both of them knowing they could never go back after such a moment shared together. While the idea of being something so different than just brothers may have felt a bit daunting, it didn’t seem like either of them felt the slightest bout of guilt or regret while within each other’s embrace. For Rumble, he finally managed to get the stallion he loved and adored for so long in secret. And for Thunderlane, he found the one pony he never expected would give him so much, but turned out to be everything he wanted and more.

Of course, a million thoughts came rushing into the Wonderbolt’s head as he laid atop his beautiful brother. Did this mean they were boyfriends now? Could he be able to keep this a secret from anypony? Did Rumble want anything deeper than a sexual relationship with him? And if so, what else could they pursue?

After a moment of thought, one thing sprung into the pegasus’ mind quicker than anything else. He opened his eyes faintly as he shuddered involuntarily, and glanced over at that coffee table across from their couch. While his brother remained soundlessly content beneath him, undoubtedly thinking of their futures together, Thunderlane exhaled sharply and said, “So, ummm… you want me to turn the oven on so we can re-heat these pizzas?”
