Chapter 1

Lounging within the lobby of the Mareiotte Hotel, doing his best to play it cool, Rumble glanced over to the elevator. The afternoon had played out perfectly so far, with all the pieces steadily falling into place, yet that was no guarantee of success - not by a long shot. Seeing a pair of unfamiliar ponies exit the lift, he lowered his head and sighed.

He’d been staying in Manehattan for the better part of six months, living with and under the tutelage of his employer Hoity Toity, and he’d changed both inside and out. A careful diet and specially selected exercise regiment had transformed him from a slender little stallion into a curvy, graceful, head-turning femcolt, and he’d only recently felt confident enough with his look and skill to pull off his magnum opus.

He hadn’t seen his brother since he’d left Ponyville, but that was only one of the reasons he’d invited Thunderlane to come and visit. Months prior, before he’d met his domineering Daddy of a host, he’d never thought of his sibling in a depraved light, but things were different now. His appreciation for tall, strong, masculine stallions had reached a fevered pitch, fueled by Hoity’s ministrations, and there weren’t many stallions bigger or stronger than his big brother.

Thunderlane was and always had been nearly twice his size, powerfully built, and held a commanding presence, which were exactly the aspects he sought out in a stud. While he couldn’t quite put his hoof on exactly when or how he’d started dwelling on his sibling, he’d found himself thinking about his brother more and more often as of late. In and of itself, missing his bro wouldn’t have been anything particularly peculiar, yet that was the problem - his thoughts had been anything but wholesome.

There had been times when he imagined it was Thunder railing him out, breeding his ass and making him howl in delight, while he’d been getting fucked by Hoity. He’d had every intention of keeping his budding incestuous interests to himself, yet he’d made the mistake of whimpering his brother’s name one evening as he was serving his host. After reluctantly admitting his depraved fantasy to his Daddy, he was presented with a notion that was as simple as it was sinful - why not invite Thunderlane to visit?

And so he’d begun to scheme. The first step had been to purchase a train ticket from Ponyville to Manehattan, book a room at the Mareiotte, and extend an invitation to his brother. Thunder enthusiastically accepted the offer straight away, and had been both proud and moved by having his trip and lodgings paid for, but that had been the easy part. Knowing he’d be seeing his sibling in less than a week, he’d spent every minute of his waking time refining his look and honing his skill.

Any stallion could don a dress and parade themselves as a mare, but to really pull it off took a profound amount of dedication and practice. Knowing how to dress, having an elegant gate, and being able to adorn oneself with makeup were all part of the package, as was being demure and genteel. Fortunately for him, Hoity had been more than helpful with his practice.

For the better part of two months, he’d lived his life as a mare. He wore dresses and skirts on and off the clock, routinely anointed himself with cosmetics, and he’d retrained himself to trot in a feminine fashion. By the time Thunder had been set to arrive, he felt more than ready to enact his scandalous plan. Peering over at the window, he looked at his reflection and grinned.

His once short mane had grown out by several inches and had been neatly styled over one eye, a form-fitting cocktail dress clung to his svelte frame, and his full, pouting lips had been painted a vivid amethyst. He looked nothing like his former self, a fact which had been evident when Thunder had checked in, noticed him, and smiled in his direction. While he hadn’t done anything at the time, simply giving a coy grin and wave of acknowledgement, he’d been overjoyed that his disguise had worked flawlessly.

Hearing the elevator chime, he snapped from his reverie and looked over to the lift. As a dark, hulking stallion stepped into the lobby, his heart skipped a beat. Like it or not, it was time to act. Slipping from the sofa, he casually sauntered towards his brother. Though everything had gone smoothly so far, he was about to face his biggest obstacle.

Intercepting his sibling at the door, he caught the stallion’s eye. “Hi - um - do you have a second?”

“Sure,” Thunder paused, turning to face the cute little mare, “how can I help you?”

He’d spotted her shortly after he arrived, lounging on one of the sofas in the lobby, but he hadn’t expected her to be there when he came downstairs to trot to Hoity’s shop - that said, he wasn’t about to complain. She was exceptionally small, looked relatively young looking, and quite attractive, scoring her multiple points in his book and immediately catching his interest. Stepping away from the door, motioning for her to follow, he quietly waited to hear what she had to say.

“This is a little embarrassing, but do you know any good places to eat around here?” Rumble asked, feeling his cheeks darken.

Actually talking to his big bro was far more difficult than he’d initially thought, though that may have worked in his favor. His blush and timid demeanor weren’t staged in the slightest, adding a decidedly real element to the encounter, but he wasn’t deterred - not after all the time and effort he’d put into his ploy. Summoning his courage to look into the stallion’s eyes, he lifted his head and peered up at his brother.

“Well,” Thunder began, averting his gaze from the adorable mare’s face, “I’m not from town, but I did pass a little bistro on my way in. I’m not sure how good they are, but something in there was smelling pretty nice!”

He knew Rumble was waiting for him, though the invitation he’d received had mentioned that his little brother wouldn’t be off work until nine that night, giving him nearly three hours to kill. While he had intended to walk around town to see the sights, the prospect of spending a bit of time with the adorable stranger was more appealing than simply meandering around by his lonesome. Smiling down at his newfound acquaintance, he motioned towards the exit.

“If you’re not doing anything, would you like to join me for a bite?” he inquired.

Rumble grinned from ear to ear, as he extended his hoof towards the stud. “I’d be delighted. By the way, I’m Stunner.”

“Thunder,” the hulking stud intoned, shaking the sylphlike mare’s dainty hoof. “It’s a pleasure to meet you.”

With Thunderlane leading the way, moving just ahead and to the side of his little brother, the pair made their leave and moved down the sidewalk. Though the elder sibling was woefully ignorant to whom his companion was, blissfully unaware that he was being accompanied by Rumble, he was pleased to have some company for the afternoon. As they steadily made their way to the cafe, the subtle game of courtship began to unfold.

The following two hours went exceptionally well, with the pair chatting, joking, and learning about one another - of course, Rumble had to feign ignorance of Thunder’s life, as well as spinning a yarn on his alter ego’s backstory and past, but he found himself growing increasingly comfortable with the charade. Barely touching the light meals and teas they’d ordered for themselves, ensconced in their conversation with one another, the time practically flew by. Bathed in the warm hues of sunset, relaxing at one of the window-side tables, their conversation took a personal turn.

“So, I have to ask,” Rumble hummed, swirling his partially emptied cup in one hoof, “do you have a special somepony?”

Thunder paused and went flush, rubbing the back of his neck. “Can’t say I do, no.”

“Me neither,” the disguised femcolt murmured, hanging his head. “Maybe someday I’ll be able to find a nice stallion like yourself…”

“Well, if you’re not doing anything later, would you like to hang out tonight?” the large pegasus asked, sheepishly smiling to himself. “I definitely wouldn’t mind getting to know you a bit better.”

Mirroring his brother’s grin, Rumble nodded. “I’d like that a lot. It’s not every day I stumble upon a gentlecolt as charming and good looking as you - if you don’t mind me saying so.”

Seizing the moment, he reached out and rested a hoof on his brother’s foreleg. While it may have been a bit brazen, he decided to push the envelope. Being familiar with Thunder’s love-life, or lack thereof, gave him an edge he would be sure to exploit. Catching his sibling unawares, he shot forward, leaned across the table, and pecked the stricken stud’s cheek. Be darned if was going to pull any punches with the big guy - that was until he’d gotten just what he wanted.

“W...well, I should probably get going for now,” Thunder sputtered, glancing up at a clock above the counter. “I’m going to be visiting my little brother soon and I should swing by my room before I head out.”

“I hope you don’t mind me walking back with you, since we seem to be sharing the same hotel,” Rumble giggled, batting his eyes.

Sliding out of his seat and stepping over to his guest, the titanic stallion offered his hoof. “Of course I wouldn’t mind escorting a cutie back to her room,” he noted, helping her to her hooves.

The pair paused and stared at one another, before looking away and trotting towards the exit. Their return trip to the hotel was done in relative silence, though their thoughts lingered on one another. While Thunder considered how he could best court the young mare, wondering if it would be out of turn to take her on a proper date, Rumble mused on how difficult it would be to cross his next hurdle.

Surreptitiously seducing his sibling had been vastly simpler than he’d originally assumed, yet doing anything lecherous would present the biggest obstacle - the fact that he was in fact a stallion. If or when they did get intimate, he had little doubt that Thunder would notice his meager endowment, which very well may bring the entire affair to a screeching halt - that said, it wasn’t by any means a guarantee of failure. A stallion’s judgement could and oftentimes would get clouded by lust, if they got worked up enough, and he had every intention of getting his brother very, very worked up.

Trotting through the hotel lobby, staying close to his brother’s side, he moved to and into the elevator. The next phase of his plan would be pivotal, either making or breaking his scheme entirely, so he took a deep breath, closed his eyes and relaxed himself. Everything up to that point had gone off without a hitch, and he couldn’t afford to make a misstep.

Listing slightly, he pressed his side to Thunder and heavily sighed. “Thank you for the company.”

Drawing a breath through his nose, only then detecting the subtle yet alluring aroma of her perfume, Thunder stiffened. “I...it was my pleasure,” he replied, pressing the button for his floor.

He could hardly believe his luck; not only had he met a very attractive mare, but she genuinely seemed to be interested in him. Resting more of his weight against her, turning his head to the side, he brought his face closer to hers. Seeing as how she’d been bold enough to give him a little kiss at the cafe, he couldn’t help but return the favor.

Giving her a small peck on the brow, he withdrew and stared into her eyes. There was something oddly familiar about her, though he couldn’t quite place it and wasn’t willing to ask. Perhaps he’d seen her at one of the Wonderbolt shows he had performed at, or maybe she’d passed through Ponyville at one point - regardless, he couldn’t shake a vague sense of familiarity about her. Remaining motionless, seeing her head creeping forward, he found his kiss repaid with dividends.

Rumble closed his eyes and stifled a groan, pressing his lips to hulking stud’s. Simply kissing anypony in a public place would have been spicy enough, but the taboo of making out with his brother elevated the experience by leaps and bounds. Testing his luck, already feeling his miniscule endowment struggling against his panties, he pressed his tongue into the Thunder’s mouth. Even if things did go belly-up, at least he could say he’d successfully smooched a straight stallion.

Much to his pleasant and unexpected surprise, his sibling almost immediately reciprocated. As the stallion’s thick, powerful tongue pressed past his lips, his eyelids fluttered. Emboldened and more than a little turned on, he pressed forward and moaned. Far be it for him to put an end to the passionate exchange, lest he risk putting an end to the escalation.

The elevator chimed and the doors steadily opened, yet neither of them stopped frenching - unfortunately for them both, the sound of a clearing throat ruined the moment. Pulling away from one another, the two turned in unison and found a mother and child lingering just outside the lift. Glowing crimson, they awkwardly excused themselves and hurried down the hallway.

“So - uh -” Thunder faltered, peeking over at his company, “any plans for this evening?”

“Aside from spending some more time with you,” Rumble cooed, drawing a hoof up his sibling’s flank.

Situated where he was, beside and slightly to the rear of his brother, he had a perfect view of the stud’s loins. Spying the semi-flaccid, coal-black length beneath his date set his heart fluttering. He’d realized that Thunder had been enjoying himself, but he hadn’t anticipated that his sibling would already be getting wood. As he tore his eyes off the impressive cock, wondering just how well-endowed the beefcake was, he looked up to the stallion’s face and froze.

Thunder slowed, having spotted the little mare eyeing his goods. He had intended on simply seeing her off and meeting again with her later, but the sudden, pointedly erotic turn gave him a moment for pause. Given how long it had been since he’d experienced any sort of intimacy, and having a somepony who clearly knew what she wanted, his typical inhibitions gave way to his mounting passion.

Mutely standing in the hallway, the duo each waited for the other to make a move. They both silently hoped that things would continue to unfold, having gone from just meeting to hotly kissing in a mere afternoon, yet there was a bit of reluctance on how to proceed. Spurred by his arousal and success thus far, Rumble struck first.

“Didn’t you say you’ve got to meet your brother?” he softly inquired.

Squatting down slightly, grinning all the wider, Thunder brought himself to her eye-level. “I might have about an hour, why?”

“Well,” Rumble purred, drawing his tongue over his lips, “you think that’s enough time to pick up where we left off in the elevator?”

The colossal stallion reared back and beamed, smoothly slipping a wing into his shoulder bag to retrieve the key to his room. Though Rumble was surely looking forward to seeing him, he couldn’t bring himself to turn down the opportunity for a bit of amorous action. Considering he may never see her again, after he returned home, he saw no harm in indulging in a fling.

Without saying a word, turning in the direction of his room, he coolly folded a wing over her shoulder and trotted towards his door. If she wanted to continue what they’d started, he’d be more than happy to oblige her. Seeing himself inside, slid the feathered appendage to her hind quarters and gave her a squeeze.

With the game well and thoroughly ahoof, Rumble had to keep himself from snickering. Unlike his brother, who’d only just worked up the nerve to cop a feel, he wasn’t one to play coy. Arching his back and wiggling his tush, he took off the gloves and abandoned the coy act.

“I wasn’t going to say anything earlier, but you surprised me,” he began, caressing the stud’s cheek with a forehoof.

Taken off guard by the comment, yet keeping his wing firmly planted on the mare’s rump, Thunder piqued a brow. “Oh?”

“Yeah,” the femcolt purred, craning his head to look at the stallion’s growing erection, “with a dick that big, I’m surprised you don’t have mares flinging themselves at you left and right.”

“Y...yeah,” the stud hesitantly remarked, looking back and down at his own equipment, “it is on the large side.”

Seeing the opening, Rumble went straight for the throat. “Mind if I get a better look?”

Taken aback by the request, Thunder felt his pulse quicken. Never in his life had he met a mare as forward as her - not that he was complaining. Withdrawing the feathered appendage and stepping away, creeping closer to the bed, he gave a small nod. If she wanted to help herself to his package, he wasn’t about to deny her.

As he hopped up and onto the mattress, lowering himself to the sheets, he rolled to his side and lifted his hind leg. “I’m not normally one to show off, but since you asked nicely…”

Rumble’s eyes went alight, as he gazed longingly at his brother’s equipment. It wasn’t like he’d ever tried to look at his sibling’s naughty bits, in spite of having lived Thunder for most of his life, but things were different now. Having fully embraced his role as a hopeless bottom and cock slut, the sight of such a magnificently presented and utterly immense stallionhood set his mouth watering.

Inching closer, feeling his ravenous pucker hungrily wink, he wiped a bead of drool creeping past his lips. Thunder wasn’t even fully hard, judging from the looks of it, and yet he was clearly as big or bigger than Hoity - which was saying a lot. Covered in dark, satiny flesh, with a prominent vein snaking along one side, there was only one word to describe the sinful appendage - perfect. Utterly transfixed by the colossal dick before him, ignoring his sibling’s reaction, he crawled onto the bed, brought his face to the stud’s ripe balls, and drew a deep breath.

The earthy, ambrosial scent of his musk flooded his sinuses, triggering the servile, bottom-bitch portions of his brain in an instant. His muscle memory leapt to the fore, as he drew his tongue over the thick flesh between Thunder’s sheath. Fully committing himself, licking his way up the massive, meaty pillar, he needily bucked his hips into the mattress.

The irony of the situation didn’t escape him; he’d grown up around his brother, saw him every day for most of his life, yet he’d never fully appreciated what the stud had to offer. A paragon of masculinity, impressively built, and with a drop-dead gorgeous body, his sibling was everything he could have wished for in a stallion, making him feel foolish for all the wasted opportunities he’d had. As he reached the profound huge, blunted cock-head, he adjusted his positioning and opened his maw.

His lips stretched around the gigantic tip, his backdoor angrily clenched, and his colthood smeared the interior of his panties with pre-cum, as he forced his head forward. Successfully throating the entirety of Thunder’s shaft would be a trial by any measure, yet his placement would make the task nearly impossible - still, he wasn’t about to throw in the towel. Reaching out with a hoof, gingerly pulling the stallionhood towards himself, he worked the length down his gullet.

“Oh buck,” Thunder groaned, watching his dick disappear into her snout.

While it wasn’t the first time he’d gotten a blowjob, it was hooves-down the fastest anypony had sucked him off - not that he was complaining. Peering down at her, seeing her look up at his face, his dick twitched in her throat. Whoever she was, she clearly knew what she was doing and held no reservations about lustful endeavors.

Slowly extending a wing to the back of her head, he gently pulled her to himself. The sight of her lips mopping his shaft and the sensation of her tongue massaging the sensitive underside of his length paired flawlessly, causing him to reflexively buck into her face. Though he hadn’t planned on choking her on his cock, the combination of his protracted dry-spell and her assertiveness proved to be a fatal mix.

Her hum of approval was cut short, as she gagged around him. Ordinarily speaking, he would have withdrawn and apologized, but seeing as how she’d been enthusiastic enough to suck him off less than a day after meeting him he couldn’t help himself. Hearing her sputter, fully expecting her to pull away, the unthinkable happened - she doubled down.

The excitement of having his brother take the lead was all the inspiration Rumble needed. Having become intimately familiar with his limits, knowing just how long he’d need before he had to take a breath, he jammed his head forward. Eyes locked on the stud’s groin, hell-bent on pressing his nose to Thunder’s crotch, his lips stretched around the medial ring.

He’d long since abandoned any desire to get himself off, instead taking gratification from serving real stallions. Hours before, when he’d gotten gussied up to intercept his sibling, he’d made sure to thoroughly clean and lubricate himself. With his ass thoroughly prepared for a pounding, having gone so far as to loosen himself up on one of his larger toys, he was in the final stretch; the last thing he needed to do was manage to get Thunder right to the tipping point.

Vehemently bobbing his head, feeling his throat bulge with the monstrous intrusion, his eyes began to water - not like that was going to stop him. At some point or another, having served under Hoity’s tutelage for months on end, he’d developed a bit of a masochistic penchant for being used. Propping himself on one foreleg, easing his chest to the bed, he tauntingly waggled his tush.

As Thunder’s eyes wandered to her succulent rear, he gnawed his bottom lip. Though her attire was relatively modest, the clinging garment left little to the imagination. A part of him was tempted to bring her ministrations to an end, if only to claim her properly, yet he stayed his hoof - at least for the time being. Taking a more relaxed stance, he relaxed and enjoyed the experience.

On and on she went, only slowing to take the occasional sip of air, as she pushed him to his limit. Curious as to how turned on she was, growing increasingly interested to sample her doubtlessly well-trained marehood, he found himself torn between watching her face and admiring her tush. As his endurance started to wane, nearing the threshold of no return, any choice he had on the matter was stripped away.

In the blink of an eye, without any warning whatsoever, Rumble pulled back and unsheathed the stud’s length from his esophagus. Though the signs had been subtle, consisting of little more than a slight throb in the massive stallionhood and a change in Thunder’s breathing, he knew his brother was close - as such, it was time to move to the final act. Steadily pushing himself up, he trotted past the reclined stud and towards the head of the bed.

Tamping down his fears, pulling a pillow beneath himself, he leaned forward, raised his hips, and flipped his tail to the side. Even if Thunder couldn’t see the bulge of his puny package, it wouldn’t be long until his secret was revealed. Twisting his head and looking back at the majestic stallion, he languidly pulled his dress up and over his behind. It was the final moment, there was no turning back, and all he could do was pray things worked in his favor.

Getting to his hooves, Thunder stood and inched closer to his guest. Her presentation was immaculate and everything he’d been hoping for. Reaching out and grabbing the waistband of her panties, he slowly drew the garment downward and revealed the supple cheeks of her rump. Her ass was positively exquisite, soft and plump, causing his stallionhood to twitch in anticipation.

As the undergarment passed her thighs, clearing her groin, he stopped dead. Where he’d fully expected to find a slavering, juicy marehood, he discovered a dainty coin purse and small, twitching prick. The sight was so startling that he genuinely didn’t know what to think, yet the facts spoke for themselves; he hadn’t been flirting and getting frisky with a mare at all - no, he’d been fooling around with a stallion.

“Just so you know,” Rumble cooed, affixing his brother with his heavily-lidded eyes, “it’s better than any pussy you’ve ever had…”

The not-so-subtle goading chipped away at Thunder’s reservations. His thoughts raced, as he hastily accessed the situation. The little mare - er - femcolt was pleasant company, had absolutely killer oral skills, and was a darn good kisser, leading him to believe that the sex would be stellar as well. Truth be told, he was having a hard time finding a reason not to fuck the harlot’s brain’s out.

It’s not like anypony would ever know he’d fucked a guy, since he was only going to be in Manehattan for a few days, and he could always deny having done anything gay - that was, if anyone ever questioned him about it. Glancing up at the femcolt’s ass, seeing the dark pucker invitingly wink at him, he reached his breaking point. In one smooth motion, he straightened up, reared back, and locked his forelegs over the sissy’s hips.

The sensation of the stud’s weight on his back was almost as captivating as having his ass prodded by the biggest, fattest cock Rumble had ever seen. Rocking back, kissing the tip of Thunder’s length with his backdoor, he reached up with his wings and caressed the stallion’s neck and chest. His brother had taken the bait and mounted him, yet the best part was still to come.

His months of practice and careful preparation paid off in an instant, as the gargantuan length ground into him. He’d assumed the intrusion would be intense, but even he wasn’t prepared for just how eye opening the experience was. His eyelids drifted closed, his thighs trembled, and a gobbet of pre leaked from his insignificant member, while his interior embraced the behemoth.

He’d been screwed by Hoity more times than he could count, and had even purchased a number of rather sizable dildos, but they paled in comparison to what his sibling had to offer. Bucking back, eager to be railed out by the stud, he whorishly groaned into the pillow. The satisfaction and taboo of having his brother’s dick inside him was almost as amazing as the feeling of having his prostate crushed and insides rearranged - simply put, he couldn’t have been happier. Feeling the stud slow and began to pull back, fearing Thunder may have had a change of heart, he was rewarded with his first true thrust.

The plunge nearly drove him into the bed, burying his face in the pillow, as he was driven forward. He’d known Thunder was strong, but even he was taken aback by the sheer force and enthusiasm of his sibling! Hastily bracing his hind legs, preparing himself for the inevitable amorous onslaught, he sank his teeth into the cushion and prepared himself.

Thunder’s thoughts ran rampant, as his natural urges to breed took the reins. While he had been hesitant to screw a stallion, the sensation of his mate’s warm, velvety canal around his length demolished his indecision. Holding the tiny trap firmly, he set his jaw and put his massive body to work. If she wanted to get fucked like a mare, that’s exactly what she was going to get.

Gradually picking up speed, caving to his lust, he moved harder and faster with each passing minute. Though he hated to admit it, she’d been right - her ass was better than any pussy he’d ever had, but that was only one facet to the wondrous experience of plowing her. Her marish whimpers of delight, how she rocked back to meet his thrusts, and the way she’d peek up at him with her pleading eyes doused his passionate fire with fuel, driving him onward.

“Oh Celestia,” Rumble moaned, as his eyes rolled back.

He couldn’t tell how long he’d been getting railed out, but he realized he wouldn’t be able to last long at the pace they were going. The stud’s giant nuts slapping against his comparably tiny balls, hearing the deep, domineering grunts, and the sheer force of being claimed by somepony so much larger than himself were divine, just what he’d been craving, yet there was one final thing he desired - something he yearned for. Forcing himself to concentrate, he skillfully milked the stud’s pistoning length with his pucker.

He’d served as Hoity’s personal slam-piece for long enough to realize when a stallion was close, and Thunder was definitely close. The one-two punch of his blowjob and the stud’s prolonged abstinence worked to his favor, as his brother’s thrusting grew frenzied. Feeling Thunder throbbing within him, hearing the heavy breaths from above, peeked up at his lover.

“Breed me,” he squealed, feeling the pegasus starting to flair. “Cum inside me, please!”

The desperate plea was the nail in Thunder’s coffin, signaling his demise. Hilting himself, he triumphantly bellowed and unloaded months of unspent seed into his mate. His cock pulsed wildly, disgorging his load into the mewling femcolt, as he grit his teeth and fitfully continued humping.

The influx of what felt like gallons of cum mingled with the knowledge that he was being bred by his brother, sending Rumble sailing over the edge. Thin, watery spunk gushed from his colthood, painting the sheets below him, as he was rocked by one of the fiercest climaxes he could remember. Locking his knees and forcing himself to remain steady, intent on taking every drop of the stud’s essence, he could already feel his gut starting to bloat from the deposit.

Though neither of them could see it perfectly, Rumble’s belly steadily ballooned outward. He couldn’t actually get knocked up, but anypony who saw him could easily mistake him as an expectant mother. With the titan slowing to a shuddering stop, draping himself over the little sissy, the pair wheezed and pulled air into their lungs.

“B…buck,” Thunder stammered in disbelief.

He could scarcely believe he’d just had sex with a guy - a cute and effeminate guy, but a guy nonetheless. To make matters worse, it had been a darn good lay, one of the best he’d ever had, and the revelation made him question just how straight he really was. Feeling his diminutive lover tremble, he grasped the femcolt and rolled onto his side with her.

While the abrupt shift in positioning was certainly jarring, Rumble found himself relieved. The stain of a fully-grown, particularly large stallion would have been hard to hold on any occasion, let alone after they’d quite literally fucked the cum out of him. Snuggling against his brother’s chest, awash in the euphoric afterglow, he contentedly sighed and made himself comfortable.

“I told you it was good,” he snickered, playfully squeezing the softening shaft buried in his ass.

Thunder nodded and playfully bucked his hips. “Y…yeah, you were right,” he breathed. Glancing over at the nightstand, he checked the time on the nearby clock. He still had an hour before he was expected to meet with Rumble, more than enough time to get cleaned up and ready, but there was something else that suddenly came to mind. “Hey,” he began, drawing his guest’s eye, “you wanna crash with me tonight - I mean, if you’re comfortable with it.”

“I’d love to,” Rumble hummed, affectionately wiggling against the giant.

He still had to find some way to escape, to get back to Hoity’s shop before his sibling, but he could work that out in a little bit. At worst, his employer would cover for him and concoct some sort of excuse for his absence - at best, he could somehow beat Thunder there and act like nothing had happened. No matter how the afternoon played out, he was sure of one thing - he’d be spending the night with the best big brother in all of Equestria…

Chapter 2

Hanging his head, Thunderlane loped down the bustling street. The day he’d arrived in Manehattan had been a very mixed bag - one that left him in a questioning haze. He managed to get laid for the first time in years, meeting a sultry little minx, named Stunner, he’d ended up spending the night with; ordinarily speaking, this wouldn’t have been a bad thing in the slightest, but there was a problem - Stunner had been a femcolt.

Truth be told, the sex he’d had with Stunner was phenominal. They’d gone at one another late into the night, doing it in all manner of wild positions both in his hotel room and the bathroom, yet their fun had eventually come to an end. After showering and going to bed, fully expectant on finding the sinful little stallion beside himself in the morning, he’d awoken to discover his guest had disappeared.

As he nearly stumbled into a parked taxi carriage, he shook his head to clear his thoughts. He’d never really considered himself gay, but he couldn’t deny what he’d done the evening prior. Not only had he fucked a stallion, he’d loved every sinful minute of it - to make matters worse, merely thinking about the hookup was enough to cause his stallionhood to slip from its sheath. Lifting his gaze and glancing over at a pair of street signs, realizing he was close to his destination, he hung a left turn and continued on his stroll.

With any luck, he wouldn’t be in too much hot water for not showing up on time - then again, his little brother tended to have a pretty laid back approach to almost everything. As he thought about his sibling, how much the little colt had grown over the years, a smile graced his lips. If Hoity Toity let him, he’d take Rumble out for lunch so they could catch up and chat.

Peering down the street, seeing his destination, he increased his pace. Yeah, a visit with his little brother would be just the thing to help clear his head and brighten his day. Though they exchanged letters once or twice a month, it felt like it had been forever since he’d actually seen his sibling. Musing on if his brother had managed to find a marefriend in the big city, he suppressed a giggle and cantered to a halt at the boutique’s door.

As he saw himself inside, a bell on the door softly jingling above him, his eyes crept across the shop’s interior. The place was well lit and extremely tidy, with mannequins displaying outfits and racks of fancy-looking garments, yet he didn’t see anypony inside. Curious and a bit perplexed, noting the vacant checkout counter, he cleared his throat.

“Hello?” he called out, remaining motionless and listening for any signs of life.

Moments before he spoke a second time, he heard something odd. A faint noise drifted from the very back of the boutique, creeping past an empty doorway leading to what he presumed was an employee only area. Hoping not to make a scene, yet concerned that something may be wrong, he cautiously navigated past the displays and closer to the source of the strange sound.

The second he poked his head into the back, he went rigid. With her forehooves resting on a drafting table, adorned in a corset and jewelry, an arctic blue mare was getting railed out by a well-built, slate grey earth pony. Stunned by the discovery, unsure of how to react, he stared at the pair and made a startling discovery; he hadn’t stumbled on a mare and stallion in the throes of passion - no, he’d happened upon two stallions.

Their lips locked, hotly making out, the duo went at one another like a pair of lovers. Thunder recognized the larger of the two, having seen pictures of Hoity, but he hadn’t the foggiest clue who the lithe femcolt was. Watching the large earth pony’s impressive endowment sliding in and out of the unicorn’s backside, reminiscing on how he’d been doing something very similar the day before, he was unable to stop his growing excitement.

“Would you like to join us?” Hoity smoothly inquired, rearing back and causing his guest to start. “I assure you, her mouth is exquisitely well trained.”

“I…I should - Um -” Thunder sputtered, his cheeks going a brilliant crimson.

In one of the rarer moments in his life, he didn’t know what to do. Standing as a silent spectator to the pair didn’t feel right, nor did spontaneously flinging himself into a very homoerotic situation, but he’d be lying if he said he wasn’t enticed. Shifting in place, nearly forcing himself to take a step back, he bashfully rubbed the back of his neck.

“I…I should…” he gulped, only then aware that the unicorn was eyeing his steadily growing erection, “I should go.”

Slowing to a very relaxed pace, yet continuing to rut the slender femcolt, Hoity reached up and lowered his shades. “I’d rather you not - after all, Rumble has been looking forward to seeing you.”

“You’re Thunderlane?” the marish stallion gasped, bringing his focus to the pegasus’ face. “Oh wow, you really are handsome.”

“Forgive her,” Hoity sighed, giving her backside a playful smack, “she’s a bit excitable. Dearest, introduce yourself.”

Rocking forward with every thrust, his meager stallionhood leaking precum beneath him, the unicorn held a hand to his chest. “I’m - Nnnph - I’m Sassy Saddles.”

Thunder would have offered to shake a hoof, had the femcolt not been getting rutted, but he held his ground. “So - um - is Rumble around?”

“Oh I’m sure he is,” the couture snickered, giving a particularly hard thrust that caused his lover to whorishly groan.

Peeking out from behind the curtained doorway leading upstairs, Rumble swallowed hard. He’d been watching since his brother entered the shop, and the first phases of the trap had been set. Before Thunder had gotten up that morning, he’d slipped out of the hotel room and scampered back to the boutique as fast as he could - not because he necessarily wanted to leave, but because there were preparations to be made. Subconsciously pawing at the collar around his neck, his thoughts began to race.

Hoity Toity, the very stallion who’d shown him the joys of being a crossdressing, effeminate femcolt, had decided it was time to move on. The designer was a stud of renown, but his passion was training svelte little bottoms on how to properly seduce and bag a lover. With his next protege scheduled to arrive in less than three months, and since Rumble’s fondness for his brother had done nothing but flourish, he’d made a shocking suggestion - instead of continuing their lives as siblings, perhaps the pegasi could move forward as mates.

Rumble was initially taken off guard by the proposal, initially rejecting it, yet he grew increasingly fond of the idea. Thunder was kindhearted, attractive, had made a name for himself, and was an absolute titan of a stallion; there weren’t many ponies who held such a dizzying array of amazing qualities, but could he really transition the stud from brother to Daddy? It wasn’t until his sibling had written to him, mentioning wanting to visit, did he finally decide he was going to do it - he was going to seduce the big lug.

The first step of his scheme was getting frisky with Thunder, having disguised himself as a mare to break his sibling’s heterosexuality. Being dicked down by his brother was simultaneously one of the easiest and most enjoyable things he’d ever done, rivaling or exceeding the bliss Hoity afforded on a regular basis, yet that was only the beginning. Now that the mohawked stud was in the stop, the most difficult portion of the plan had yet to unfurl.

As soon as he’d gotten back to the boutique, knowing his brother would be coming by sooner rather than later, he’d gotten himself ready. A thorough shower had come first, cleaning himself both inside and out, but that’s when things got tricky. Unsure of exactly where his sibling’s preferences lie, he’d had to guess on what accouterments to wear - fortunately for him, he had an excellent tutor.

Under Hoity’s direction, he’d selected a leather choker and leggings, all in a vibrant pink, as well as some lipstick, mascara, and a touch of blush. By the time he was done up, even without anything to conceal his relatively diminutive package, he could easily pass for a mare. Lingering just out of site, dolled up and as ready as he’d ever be, he steeled his resolve and stepped past the curtain.

“I’m right here,” he sighed, his sultry voice drawing the buff pegasus’ eyes over to himself, “Daddy.”

Thunder’s jaw nearly hit the floor, his stallionhood reflexively twitched, and his heart leapt into his throat, as he stared over at the drop-dead gorgeous pony. It took him a second to fully comprehend what he was looking at, recognizing the voice and the figure, but a part of him refused to believe his eyes. Somehow, in spite of spending years around the little stallion, it took him a second to realize he was looking at his very own brother.

“Rumble?!” he croaked.

Giggling, the femcolt coyly held a hoof over his muzzle and drew nearer. “Surprised to see me, Daddy?”

“I…I…” his voice trailed off, looking between his sibling and the couture. “Wait wait wait, you’re Stunner?”

“Something the matter?” Hoity inquired, still lazily pounding Sassy’s ass. “Perhaps you’d like a seat to gather your thoughts.”

The designer and his horned protege shared a knowing look, before the unicorn’s horn went alight. In the blink of an eye, Sassy levitated and moved a chair behind the stunned stallion, setting him off balance and causing him to fall back into the cushioned seat. The entire affair was like a chess match, though Thunder was at a disadvantage; being outnumbered three to one, with the trio having conspired against him, he never stood a chance.

Right on cue, Rumble sauntered over, swaying his hips back and forth, and stopped before his brother. “You look surprised…”

“Darn right I’m surprised,” Thunder blurted, gazing down at his sibling.

Had he not known better, he could have sworn he was looking at an adorable little mare. The rough and tumble brother he’d grown up with was all but gone, replaced by a curvy, graceful, and frighteningly attractive pony - heck, Rumble even sounded more feminine. Unsure of what to say or do, feeling like a fly trapped in a web, he watched the little pegasus reach out and delicately caress his stallionhood.

“Surprised you bred a femcolt last night, or surprised that you bred me?” Rumble giggled, his mouth starting to water.

“B…both,” Thunder stammered, “everything!”

“Ahem -” Hoity coughed, drawing everypony’s attention, “perhaps I can explain. You see, Thunder, you’ve been confused; you don’t have a little brother - no, not by any means, you have a sister. She’s always had certain predilections; I simply refined and elevated to their natural, beautiful state ~ isn’t that right, Rumble?”

“Mmmhmm,” the femcolt hummed, licking his chops.

Staring at the imposing stallionhood, fondly recalling how it had felt inside of him, he inched between the Wonderbolt’s thighs, reared onto his hind legs, and kissed the tip of his brother’s length. Stars above, he could still taste the stud’s seed, smell the heady musk, and practically feel the cum lingering deep in his bowels. Hoity was a fine top, one of the best around, but Thunder - Thunder was something special.

Thunder shuddered, the warm embrace of the young pegasus’ mouth sending a wave of pleasure through him. “F…fuck.”

“As I was saying, fair Rumble’s time with me is at an end - as such, I feel like you’re the best candidate to tend to her needs,” Hoity continued, the unicorn beneath him bucking back against him.

“N…needs?” the Wonderbolt parroted, somewhat reluctantly tearing his eyes off the impromptu blowjob he was receiving.

The couture nodded over at his guest, leaning in and pressing his chest against Sassy’s back. “Little Rumble has gone on and on about how much she cares about you, how much she longs to devote her body to you, and she pines to tend to your every stallionly need. I’m aware that you may not have given much consideration to femcolts before, few stallions do, but I can assure you that they’re superior to a mare in every conceivable way.”

Feeling the pair of warm, pouting lips creeping down his shaft, sensing the head of his cock slip into the snug confines of the colt’s throat, Thunder stifled a blissful whimper. He’d been with a few mares in his day, including a number of one-night stands after shows, but there hadn’t been a single one who had the oral skills Rumble had. Staring into his brother’s - no, sister’s eyes, watching her pull back and smear lipstick over his shaft, something clicked.

There was no possible way Rumble would be forced to do anything, let alone something as taboo as fooling around with his own family, which meant one thing - Rumble genuinely wanted to please him. Maybe his sibling had hidden his fantasies from him, or perhaps he’d simply been ignorant - in either case, the truth was laid bare. He really didn’t have a younger brother, he’d had a little sister beside him all along. Reaching down, he gently caressed the young pony’s cheek.

“Is that true?” he breathed, his voice no fainter than a whisper. “Do you really want to be with me like this?”

Rumble hadn’t anticipated the heartfelt question, presuming the beefy stallion would cave to his baser urges to claim him, so he paused. Pulling away, clearing his gullet of the downright godly cock, he softly cleared his throat. It was funny - he hadn’t hesitated to suck his sibling off, yet the prospect of confessing his feelings brought butterflies to his stomach. Taking a deep breath to calm his nerves, he slowly exhaled and locked eyes with his brother.

“It is,” he quietly replied. “I…I’ve always thought you were attractive, but it wasn’t until I met Hoity that I learned to fully appreciate it - appreciate you. I…I just,” the voice hitched in his throat, as he averted his gaze. “I just don’t ever want to lose you. I love you, Thunder.”

The spontaneous admission was as surprising to him as anypony else, plucking at his heartstrings. Though he’d thought fondly of his brother for years, it was only then that he truly understood what he had - what he risked losing one day. The sex with Thunder was amazing, and he felt sure it would only get better with time, but he wanted to make sure the big lug was happy - truly happy and well cared for for the rest of his days.

Thunder’s heart skipped a beat, hearing the confession. While he still wasn’t sure how to feel about being duped into screwing a femcolt, he couldn’t stand to see Rumble in such a forlorn state. Extending his wings and gently pushing his sister away, he eased himself to the floor, squared his shoulders, and pulled the little pegasus into a hug.

“Rumble,” he sighed, sweetly patting the small pony’s back, “if this is what you want, what will make you happy, I’ll do everything I can for you.” Stepping back only slightly, he bashfully smiled. “I can’t really say I know much about this kind of thing, but I’ll - Ooomph!”

He wasn’t able to finish, tackled to the floor by a blur of pink and grey. It took him a moment to realize he was on his back, and another second more to comprehend Rumble had tackled him, but it was too late. Grabbing his cheeks, turning his face forward, the svelte femcolt dipped his head and locked lips with him. His wings flicked out in excitement, and his thoughts raced, before he closed his eyes, accepted his fate, and passionately kissed her.

Practically swooning, Rumble pressed his tongue past his brother’s thick, soft lips. His time with Hoity had been absolutely amazing, showing him a side of himself he’d suppressed for far, far too long, yet it had lacked an element he hadn’t known he’d needed - passion. His emotional connection with Thunder, the kiss, and the acceptance of who he was worked in concert, bringing him a joy like he’d never known.

“Daddy,” he sighed, pulling away and burying his face in the stud’s powerful neck, “you don’t know what this means to me.”

“I think I do,” Thunder chuckled, keenly aware of the rigid, diminutive colthood pressed against his belly. “I just didn’t -”

“Aaaaaaahn,” a slatternly cry cut through the air, bringing the sibling’s attention to the side.

Her legs quaking and threatening to give out, Sassy climaxed from the designer’s rutting. A weak dribble of cream dripped and sputtered from her slender length, painting the floor, as she bit her lower lip. Unbeknownst to one another, watching the lithe unicorn peak, Thunder and Rumble silently pined to reenact the scene themselves.

“My apologies,” Hoity tutted, slowing only marginally, “she’s a bit of a romantic. Please, if you two would like to consummate your newly confessed feelings for one another, by all means, feel free to join us.”

Hearing the proposition, the siblings looked to one another. There were a million places they could have gone, dozens of things they could have done, but something about that magical moment resonated with them. In less than a day, the pair had had a number of revelations, and they were led to a single, ineffable conclusion - they belonged together.

Driven by the roaring inferno of his passion, Rumble was the first to act. He couldn’t care less that they were in a studio, nor was he concerned that he and his brother weren’t alone; his only concern was that he give himself to his lover, right then and there. Hopping up and onto a low-sitting drafting table, he rolled onto his back and shuffled to the very edge of the wooden surface.

“Daddy,” he pleaded, drawing his forehooves down his hind legs, “I need you…”

Thunder had seen all manner of things in his day, from groupies flinging panties at him to some extremely wild shows at bars, but the sight of his sister struck him like a gong. The memories of how staggering the sex with her was mingled with his love for her, transcending his lust into something all the more powerful. He didn’t want to claim her - he needed to claim her.

Scrambling to his hooves, he all but flung himself upon her. His forehooves slammed to either side of her willowy chest, the broad tip of his cock kissed her winking, slickened hole, and his breath steamed the air, as he braced his hind legs and got into position - unfortunately for them both, it wasn’t meant to be. The light yet unmistakable sound of a clearing throat caught his ear, and he begrudgingly glanced over at his host.

Still lazily fucking the whimpering unicorn, Hoity lifted a hoof. “Slowly,” he instructed. “There is a time and a place for asserting one’s self, but you should both savor it. Let her appreciate how wonderful you are, while you cherish how fabulous and submissive she is.”

“I…I really wouldn’t mind if you take it slow -” Rumble added, blushing beneath the titan, “at least at first…”

“Oh I think I can do that,” Thunder rumbled, angling his hips and playfully grinding his length over her small package.

Rumble stared down his chest at the behemoth, seeing the tip come nearly to the bottom of his rib-cage. He absolutely adored getting plowed in any position, but there was something undeniably chanting of being on his back, leads spread for a stallion. Something about being able to look up at his lover, watching their chest heave above him, made him tingle all over.

As he reached out with his lower legs, resting his fetlocks on his brother’s robust hips, he smiled. “Can I ask you something?”

“Go ahead,” the Wonderbolt replied, grinning.

“You don’t - um -” Rumble faltered, fidgeting in place. “You don’t mind if I call you Daddy ~ do you?”

The colossal pegasus grinned from ear to ear, bringing his snout to within a hair’s breadth of the femcolt’s face. “Of course I don’t, Babe.”

Unable to think of a reply, Rumble’s eyes widened ever so slightly. Even though he’d been under Hoity, figuratively and occasionally literally speaking, for months, he’d yet to earn a moniker - sure, the couture referred to him in the female sense, but he didn’t have a pet name. Staring into his Daddy’s eyes, feeling a magical connection forming, he slowly nodded.

“In that case, Babe,” Thunder purred, rolling his hips back and bringing his cock-head to his sister’s winking hole, “let’s get started…”

With but the slightest bit of force, he popped into the femcolt’s warm, snug confines. Just as incredible as the night before, he hummed in satisfaction. Related or not, Rumble had the best ass he’d ever had the joy of experiencing. Bracing his hind legs, forcing himself not to dive in at full force, he did as Hoity instructed and gradually delved deeper and deeper.

Pushing himself up slightly, he lowered his head. His eyes drank in the femcolt’s alluring features, from the flushing face to slender waist, until they settled on his intrusion. Watching his length slip into his comparably diminutive lover, his dark shaft contrasted against the stuffed light-grey hole, chipped away at his self-control - still, he kept his unhurried pace. He’d be willing to wait until he was fully hilted before dialing up the intensity, if only to let his sister warm up a bit.

Staring down at his flat little belly, Rumble watched the imprint of his brother’s stallionhood creep into his abdomen. The indescribable sensation of being filled by something so big was accented by being able to see the thing buried in him, heightening his arousal to an unfathomable level. Flexing his legs, drawing the stud deeper, his eagerness reached a fevered pitch. As much as he appreciated Thunder taking his time, he wanted nothing more than to be pinned down and roughly fucked raw.

“Sweet Celestia -” he groaned, his colthood drooling pre-cum over the clearly visible bulge in his stomach, “you’re so big.”

“And you almost have all of it,” Thunder cooed, grinding his girthy medial ring against her hole. “Just gotta…”

As he spoke, his hips steadily pressed harder. It was painfully obvious that Rumble had plenty of experience taking dick, but the small pony hadn’t likely dealt with many stallions his size; even compared to Hoity, who seemed pretty well-hung himself, he was on the larger side. With a determined grunt, growing impatient to begin, he gave a fierce thrust and hilted himself.

The second he fully sheathed his length, Rumble howled out. For a fleeting moment, Thunder thought he’d hurt her, but then realization settled over him. Her pucker spasming fitfully, quivering and writhing beneath him, the femcolt painted herself with jizz. Somehow, in spite of having just begun, he’d managed to quite literally fuck the cum out of her; it was quite possibly the hottest thing he’d ever seen, and it dealt a crippling blow to his restraint.

Fighting through his rapture, Rumble looked into Thunder’s eyes, drew a breath, and clenched his ass. He could have just laid there, as many bottoms would have, but he was better than that; though he may be the one getting plowed, he wasn’t one to take an inactive roll. With a deep, throaty moan, gyrating his hips all the while, he winked up at the towering stud.

“Fuck me, Daddy,” he silently mouthed, given an unspoken voice to his desires.

The titan pulled back and plunged into a second time, then a third and a fourth, until he was being plowed in earnest. The overwhelming sensations were everything he could have ever wished for from a lover, but the view of his new Daddy’s adonic features, powerful chest, and smug grin were what sank the nail in his coffin. In that moment, softly mewling and milking the shaft pistoning into him, he knew he’d found a lover of renown.

Seeing his sister’s tiny, softening prick oozing cum, finding the sight far hotter than it had any right to be, Thunder shifted his focus to her face. “You’re so - Unf - fucking hot.”

“I…I’m - Oh buck!” she croaked, arching her back. “I’m all yours, Daddy!”

Be Be darned if Thunder could explain why, but he’d never been more turned on in his entire life. Some mystical combination of the taboo, embracing a side of himself he didn’t know he had, and discovering several kinks he’d never considered before nearly drove him into a frenzy. Dipping his hips and altering his thrusts, he directly accosted her sensitive p-spot. If he was going to become her Daddy, he’d need to properly assert himself.

Propping himself on one foreleg, he reached to his hip, grabbed Rumble’s fetlock, and wrenched her hind leg to the side of her head - quickly following suit with her other lower limb. While there was nothing wrong with good ‘ol missionary, nothing quite beat a mating press to show somepony who’s boss. With the femcolt pinned beneath him, totally immobilized, he dipped his head and pressed his lips to hers.

There were a thousand and one things Rumble would have said, sinful promises to confess to his Daddy, yet all he could do was moan into the stud’s - his stud’s mouth. Thunder was a mountain of a stallion, far larger and more heavily built than most, and he absolutely loved the position he’d been forced into. With the colossus’ tongue jammed into his muzzle, he constricted his pucker with every backstroke.

He’d always been small compared to others his age, but Thunder utterly dwarfed him in every conceivable way. His brother was a paragon of masculinity, being remarkably robust and well-built for a pegasus, and every part of him deserved to be worshiped. With the stud’s breath hot on his face, practically smelling the giant’s lust, his passion soared. This was where he belonged, being subjugated by somepony exponentially superior than himself, and his refractory period all but disappeared because of it.

Slipping his head to the femcolt’s ear, Thunder’s domineering side crept to the fore. “You like that?” he murmured, taking a moment to flex his stallionhood. “I bet you’ve always wanted me to bend you over and breed that fat little ass of yours…”

“D…Daddy!” Rumble brayed, burying his face in the stallion’s shoulder. “Breed me, Daddy - breed me, please!”

Thunder had every intention of giving her what she wanted, but he wasn’t about to offer it freely. Despite what Hoity had done with her, he was going to claim her as his own, make her the perfect little mare to serve him morning, noon, and night. They already shared a roof, their parents had moved nearly three years prior, and they could easily share a bed - all in all, it was a match made in heaven.

The thought of coming home to her after a long day, finding her in the kitchen, all dolled up and wearing an apron, pushed him past the threshold. It didn’t matter if she wasn’t a mare, not as long as she was willing to keep him happy while being an adorable piece of eye candy. Subconsciously pulling out the stops, nearly plowing her through the table, he set his jaw and fought against his inevitable release.

Barely able to think, lost to his bliss, the sensation of Thunder’s flaring, throbbing cock shook Rumble from his thoughts. His old life felt like a distant memory, he finally found the perfect stud to look after him, and he took genuine joy from who he’d become - nevertheless, there was one thing he had to do. Forcing himself to focus, he threw his head back and gave voice to her thanks.

“I love you,” he howled, teetering on the brink of yet another climax. “I love you so much, Daddy.”

The admission did Thunder in, erasing his composure and casting him into a fathomless sea of ecstasy. As pint after seething pint of rich, virile essence coursed through his wildly pulsing shaft, painting his nubile lover’s depths, he bit down on the femcolt’s collar and cemented his position as her breeding stud. His balls churned, emptying into his braying sister, while he was overcome with rapture.

Rumble had experienced many orgasms in his life, yet the climax which wracked him was different - an order of magnitude more powerful and profound than those before. If he had to choose one word to describe the event, he’d call it cathartic. Like the final piece of a puzzle slipping into place, finding his niche in the world, he was made complete. Though every ounce of cum had been fucked out of his svelte body, the ecstasy which washed over him robbed him of his consciousness.

The last thing he remembered was blurrily looking up to Thunder’s handsome face, the pressure mounting in his abdomen, and the thought of a bright future for him. He couldn’t speak for his brother, but he had everything in his power to be the perfect mate. In everything but sex alone, he swore to himself that he’d be the perfect little housewife for his stud. With a weary, overjoyed smile on his face, he slipped into the warmth of oblivion and blacked out.

Sweat coated Thunder’s body, his chest heaved, and his coat steamed the air around him, as he gazed down at the slumbering femcolt. As impossible as it may have seemed, even though Rumble had been all along, the sex had been even better than the night before. Seeing the contented, exhausted look on her slumbering face, keenly aware that her cum-swollen belly’s gravid appearance, he smirked.

He’d only just discovered how much she truly cared for him, and he already had a number of ideas to do once they got home. If he played his cards right, with a bit of help from Hoity, there was a very real chance that nopony would even recognize her as his sibling. So long as he could cook up a relatively plausible backstory, he wouldn’t be coming back from Manehattan with his brother - no, he’d be coming back with his marefriend. With a sunny outlook ahead of them, somehow knowing things would work out for the best, he leaned in and kissed her cheek…

Chapter 3

Flitting down from the heavens, Thunder descended through a thin cloudbank, spotted Ponyville beneath him, and smiled. He was typically in good spirits after practice with the Wonderbolts, regardless of how intense the training was, but he’d recently been almost ecstatic to get home - not just because it meant he could relax and unwind, but because there was a special somepony waiting for him. Subconsciously increasing his speed, he sailed over the small city and down to the street.

As he touched down on the sidewalk before his house, he noticed a silhouette moving inside the home. He hadn’t realized how lonely it could be living by himself until Rumble was gone, having joined Hoity Toity on a prolonged internship, but that wasn’t an issue now. Trotting to the front door, he retrieved a key from the breast pocket of his flight suit, unlocked the deadbolt, and saw himself inside. The moment he stepped past the threshold, the aroma of freshly baked pastry sailed to his sinuses.

It would have been proper for him to announce himself, yet a sudden compulsion kept him from saying a word. Out of the foyer and through the living room, following his nose, he made his way to the kitchen. His practice had run a little longer than usual, ending just as the sun had started to dip over the horizon, so he wouldn’t be surprised if there was already dinner waiting for him. Peeking around a doorframe, staying as quiet as he could, he finally spotted her.

Bending over and retrieving a pie from the oven, adorned in naught but an apron and wing-mits, she smiled and hummed to herself. Covered in grey fur and plumage, with her black hair grown out and curled, she was the picture perfect image of an adorable little housewife, even if she was technically a stallion and his little brother. Grinning from ear to ear, waiting until she was facing away, Thunder crept over to her.

It had taken a little time to adjust to Rumble’s changes, but the transition had been much easier than he’d anticipated. For all intents and purposes, he’d lost his little brother and gained a lover without peer. Though she retained her stallionhood, a remnant of who she once was, every part of her, from her aesthetic and voice to her personality and servile nature, was a mare - as such, both she and Thunder had taken to referring to her in a female sense.

“Hey, Babe,” Thunder purred, stepping over her and sliding his chest against her back. “You making something special for me?”

Rumble started, nearly dropping the steaming pie, and craned her head to peek up at the stallion above her. His sonorous tone, the heat of his body, and the way he treated her were heavenly - nevertheless, she fought back a silly little grin. Trotting forward, determined not to give the massive stallion a sliver of attention, she trotted to the dinner table and deposited the pastry.

“You’re late,” she huffed, scrunching her snout and turning to face him.

Thunder rolled his eyes and smirked. Though Rumble had changed a lot, she’d never quite lost her hallmark sassiness. Lumbering over to her, he dipped his head and pecked her nose. Even on the off chance that she was actually upset, he knew just what to say and do to make her putty in his big, strong hooves.

“Don’t be such a grump,” he snickered, rising to his full height. “I didn’t know the practice was going to run late, I promise!”

The petulant look in her eye wavered, as she glanced from his face to broad chest. Out of all the ponies he’d ever met, he couldn’t think of one that was more insatiable in the bedroom. Unable to keep from teasing her just a little bit, hoping to take her mind off his tardiness, he unzipped the front of his suit and revealed his sweat-slickened coat.

Shaking her head and clearing her thoughts, Rumble glowered up at him. “Well I put the hayburgers in the oven to stay warm, but don’t blame me if the sweet potato fries aren’t as crispy as they were thirty minutes ago.”

“Babe,” the titan cooed, stepping forward and pulling her to himself with his wings, “like I’d be bothered by a little thing like that.”

Pressed against his chest, unprepared for the spontaneous embrace, she unwittingly inhaled his masculine scent and shuddered. If there was one thing about him that never failed to get her a bit turned on, it was his natural smell - well that and the sheer size of him. It didn’t help much that she was small by any standard, being shorter than most mares, but she wasn’t complaining.

Simply put, Thunder was everything she could have asked for in a stallion; he was tall, well-built, and was a veritable paragon of masculinity. While she’d adored his time with Hoity, being shown how to seduce and service studs, she’d fallen head over hooves for her brother - or should she say Daddy. Subconsciously rubbing her cheek against him, basking in his aroma, she felt her colthood slip from its sheath.

There was simply no staying upset with him, no matter how hard she tried. All it took was a few honeyed words or his powerful embrace to have her wrapped around his hoof, and they both knew it. As he withdrew his wings and shuffled back, leaving her to peer up at him, he lowered his head and brought his face to eye level with her.

Giving her a wink and a smile, he softly snorted over her face. “I’m sorry I made you wait, Honey.”

He already had a darn good idea of what he could do to cheer her up, but hearing her say it was an opportunity he wasn’t about to pass up. Since he’d gotten her home, she’d become even more submissive than she’d been in Hoity’s shop. In every conceivable way, barring her adorable little colthood, she was the perfect little mare - his perfect little mare. Drawing a forehoof up her chin, he lifted her head to face him as he stood.

“Anything I can do to make it up to you?” he softly inquired. Hearing his question, she blushed and averted her gaze. “Come on, there has to be something I can do…”

There was definitely something he could do, but Rumble was reluctant to openly ask for it. Though she absolutely loved her moments of intimacy with him, she cherished his little acts of affection. The way he hugged her, complimented her, and casually flirted were all incredible, but his kisses - sweet Celestia, his kisses never failed to make her weak in the knees. Closing her eyes and standing on the tips of her hooves, she pursed her lips and gave her unspoken request.

A tense second passed, before her stud locked lips with her. She would have been happy with a little peck, even on the cheek, but apparently he’d meant what he’d said - he wanted to make up for his tardiness. As his wings wrapped around her neck and the back of her head, holding her still, his tongue pressed into her muzzle. The passionate gesture was all it took to make her backdoor hungrily clench upon itself.

Though she couldn’t say how long they’d stood there making out, the moment ended far too soon. Her eyes drifted open, as their lips parted, spying a smug grin on the stallion’s adonic face. There’d been a time in her life where looking at Thunder in such a way would have been unthinkable, but that age had passed - replaced by her new life and the new dynamic they’d cultivated with one another.

“There’s that little smile,” the stud noted, making her cheeks darken further. “Feeling better?”

Fidgeting in place, keenly aware of just how turned on she was getting, she turned her eyes to the floor. “A little bit..”

“A little bit?” Thunder balked, feigning shock. “Well that won’t do at all! I can’t have my Baby Girl only forgiving me a little bit!”

The surprised look on Rumble’s face, taken off guard by his little charade, was too perfect, and it gave him just the opening he needed. Taking one massive step forward, he stooped down, extended his wings and one foreleg, and scooped her up in a princess carry. Picking her up was easy enough, considering the disparity of her sizes, but simply hoisting her from the ground was only the first part of his impromptu plan. Lumbering out of the kitchen and through the home, he made a beeline to their private chamber.

So help him, if he was able, he’d make Rumble his wife. She had a higher sex drive than any mare he’d ever met, she was faithful to a fault, and he’d developed a taste for literally fucking the cum out of her. He couldn’t say if it was funny or sad that he’d ever considered himself straight, because she was easily the best lay he’d ever had. As he entered their bedroom and approached the bed, he slowed and gingerly deposited her on the mattress.

“Now then,” he continued, placing his forehooves on the padded surface, “how about you tell me what I can do to make it better…”

Resting on her belly, Rumble watched him push himself up on his forelegs. Her eyes wandered from his face, down his neck and chest, and to his loins, locking onto the massive bulge at his groin. Situated as she was, laying atop the low-resting bed, she was at almost perfect eye-level with his immense endowment, and the sight of his package made her heart skip a beat.

The soft sound of a throat clearing sundered her trance, bringing her attention back to his face. “Well,” he sighed, “I’m waiting.”

She gulped, realizing she’d have to give voice to her desire. “May I?”

“May you what, Sweetheart? Good mares know how to speak up,” he tutted, flexing his pelvis and causing his length to slap against his belly.

“May I kiss it, Daddy?” she inquired, her mouth watering at the thought.

Striding over her supine frame, bringing his crotch to within inches of her face, he gave her just what she wanted. “You may.”

She repositioned herself ever so slightly, wriggling beneath him while she reached up with her wings. His suit sported a zipper along the back, allowing him to don or doff the garment with relative ease, yet there was also a concealed zipper along the underside of the garment. Skillfully pulling at a crease in the fabric, feeling a little metal tab against her pinion, she slowly opened the crotch of his outfit.

As the colorful cloth parted, his stallionhood was slowly revealed. Even more hung than Hoity, which was really saying something, Thunder’s endowment was a sight to behold. Nearly as long and as thick as her foreleg, with a blunt crown and large vein snaking along one side, his endowment was as imposing as it was impressive - that said, it was far from the only thing he had going for him. Before she could even fully open the fly, his cock flopped out and onto her face.

Drawing a deep breath through her nose, feeling the staggering weight of his tool resting on her muzzle, she was unable to suppress a whimper. Having worked up quite a sweat at practice, his musk was intoxicating. Practically huffing his scent, she crawled back, lifted her head, and pressed her lips to the tip of his length.

Thunder lowered his head and looked back, watching the eager little fembolt hotly make out with his dick. He’d assumed she wouldn’t be content with just a kiss, but he wasn’t about to stop her - if anything, he’d planned on her seizing the initiative. Releasing the sensations her skillful muzzle and tongue afforded, he allowed her to suck him off.

Aside from feeling amazing, the sight of her worshiping his stallionhood was a treat in and of itself. She’d taken to wearing makeup on a regular basis, since moving back in with him, and the sight of her colorful lipstick smeared along his length was almost painfully arousing. Reining himself in, doing his damnedest not to buck into her face, his bestial urges grew stronger with every passing moment.

Filling her lungs, feeling the blunt tip of cock reach the back of her muzzle, Rumble pressed her head forward. The taste of fresh sweat bathed her palate, her esophagus stretched around the huge shaft, and her tongue skillfully played over the sensitive underside of his shaft, while she kept her eyes on his groin. Since he’d been gracious enough to let her indulge herself, she wasn’t going to stop until his big, meaty balls were pressed to her chin.

“Glk,” she choked, as his medial ring slipped past her lips and strained jaw.

She could practically feel his stallionhood reaching her stomach, but that wasn’t going to stop her. A proper mare could fully throat her lover, and that’s exactly what she intended to do. Further and further she pressed, her eyes watering and neck bulging from the strain, until she’d accomplished her goal. It wasn’t until she ground her nose into the fleshy folds of his sheath did she slowly and methodically withdraw.

Having to crawl backwards to get herself fully clear, mopping his length with her pouting lips, she freed her muzzle with an all but audible pop. Though she’d never explicitly asked him, she had to assume she was one of the very few ponies who could fully sheath him in their muzzle. As badly as she would have liked to fuck him, she didn’t want to come off as too needy - after all, her stud’s needs were far more important than her own.

“Rumble,” the titan hummed, causing her to gaze up and over at his face, “you said you were going to kiss it - just kiss it.”

She went right, realizing she’d erred. Not only had she spontaneously sucked him off, but she’d further delayed their already late dinner! Fretfully gazing up at him, she swallowed hard. Though she may not be in any real trouble, the mischievous glint in his eye told her he had something planned for her.

Lifting and waving a hoof, his wolfish smirk broadened. “Since somepony seems a little needy, how about you roll over for me.”

Doing as asked, staying beneath him, she twisted onto her back squirmed to the very edge of the mattress. She had to know what he was thinking, given that she hung her head over the side of the bed, but that wasn’t going to stop him from giving it to her. Since she’d helped herself to more than just a taste, he saw no harm in giving her just what she wanted.

Backing away slightly, keeping his head lowered to stare down his chest, he brought the head of his cock to her awaiting face. As he got into position, she eagerly opened her muzzle for him. There weren’t many things hotter than a mare who yearned to be used, yet he’d somehow gone most of his life with the perfect one hiding right under his nose. Taking a moment to get himself properly aligned, he bucked his hips and sank into her snout.

Having her warm him up and get him off was all well and good, but taking charge and rutting her couldn’t be beat. Steadily driving his stallionhood down her throat, he shifted his focus and watched her grind her plump little thighs over her colthood. Like many times before and many times yet to come, she refused to touch herself while he used her; she was an exquisite mate, only caring for his pleasure, and he loved that about her.

He slowed as his medial ring entered her muzzle, steadying himself and relishing the warm snugness of her gullet. Though she could fellate the entirety of his shaft, he saw no purpose to being overly rough. There was a goldilocks depth for rutting her face, going neither too deep nor too shallow, and that’s exactly what he aimed for. With everypony in their place, he braced his hind legs, withdrew a portion of his length, and started thrusting.

Thunder’s weighty, pendulous nuts lazily slapped against her face, she was only granted periodic sips of air, and her prick drooled pre-cum like a broken faucet, yet Rumble was in heaven. This was her purpose, servicing actual stallions in any way she possibly could, and there was no greater joy than to be used by a huge, virile stud. Reaching out with her forelegs, she lovingly fondled his ripe balls while he rhythmically plunged into her muzzle.

The aroma was overwhelming, the salty flavor of sweat was gradually joined by that of cloying pre-cum, and his soft grunts grew deeper, as he steadily increased speed. She would have gleefully choked herself on him had he asked, but laying there and having her throat swabbed was far from unpleasant. Gagging around him, feeling her pucker angrily seize from the lack of attention, she closed her eyes and relished him for who he was.

“That - Nnnph - excited ~ eh?” he rumbled above her, shifting and breathing hotly on her meager endowment.

Even if she could have answered, what was she supposed to say? She was so hard that it hurt, she could feel drops of thin, watery pre-cum dripping onto her belly, and there was a very real chance she’d cum just from serving him. There was no hiding the fact that he could make her climax with perilously little effort, yet he enjoyed teasing her about it all the same. Seconds after speaking, apparently hoping for an answer, backpedaled and hauled his slickened cock from her maw.

“Well?” he pressed, quirking a brow and gazing down at her.

“Y…yes, Daddy, you know I can’t help it,” she murmured.

He beamed and dipped his head, caressing his cheek against the side of her muzzle. “Such an honest little mare.”

Straightening up and stepping to the side, moving from directly over her, Thunder pulled himself up and onto the bed. It was obvious that they’d crossed a threshold, being too worked up to simply drop everything and have supper - fortunately for them, he had a solution for their little problem. Standing over the dead-center of the mattress, he flopped to his side, rolled onto his back, and rested his head on the pillows beneath the headboard.

“Daddy had a long day,” he whispered, looking past his towering stallionhood at her.

She practically scrambled to her hooves, glancing between the meaty pillar between his thighs and his smiling face. It wasn’t everyday that she got to be the one in control, much preferring to be bent over and railed into a coma, yet there was a certain joy in being able to do most of the work. Stepping to his side, she threw a leg over his waist and seated herself on his upper thighs.

“Yeah,” he chuckled, admiring the disparity of their packages, “you like that, don’t you?”

Gazing down at her crotch, Rumble numbly nodded. Thunder’s stallionhood came to just below her ribcage, utterly dwarfing her diminutive prick. She couldn’t remember the last time she’d actually gotten off by using her equipment, so having a cute little cock suited her just fine. Rolling her hips forward and back, grinding their lengths together, she leaned forward.

“Daddy,” she breathed, dragging her face up his chest, “are you comfy?”

Extending a wing and caressing her back, he nodded. “Sure am, Babe.”

Flexing her legs, she raised her waist and inched forward. Playing with him was all well and good, yet she was nearing her breaking point. Despite having fooled around with him that morning, with their cuddling turning into a spontaneous and loving bout of lovemaking, she pined to feel his fat stallionhood filling her depths. As the tip of his shaft slipped between her pillowy buns, nudging her slick, pronounced pucker, she reversed course and gingerly applied her weight against his towering dick.

Allowing her weight to do most of the work, with his cum from that morning to lube her hole, she eased herself down. She was more than ready for him, even without anything to further slicken his length, and she had every intention of letting him know it. Stifling a small gasp, as her hole stretched around the battering-ram like head of his shaft, she gnawed her lower lip.

Though they’d fucked more times than she could count, in all manner nearly every position imaginable, the sheer size of his stallionhood was beyond impressive. The way he filled her, his heat radiating through her core, was beyond reproach. Little by little, savoring every inch of his godly endowment, she slipped lower and lower until her entrance kissed his medial ring.

“Mmmmmm,” Thunder purred, pressing his rear hooves to the mattress and bracing his hind legs.

“You like that?” she mused, leaning back and resting her back on his thighs. “Just look at how big you are…”

She didn’t need to look to know his stallionhood was bulging her belly - after all, she could feel it. Running one forehoof down her deliciously flat, furry chest, she gingerly stroked the imprint of his shaft. Hoity had a massive cock himself, but Thunder was bigger in both length and girth. As she held herself steady, shamelessly displaying the swell in her abdomen, she failed to notice her Daddy tensing his legs.

Mutely bucking his powerful hips, driving the base of his shaft into the femcolt, Thunder caused her to mewl out in bliss. While it was a nice change to let her ride him, he couldn’t help but have just a bit of fun with her. With his initial thrust having set her off balance, he eased his hips back down to the mattress and fell still once again.

Adjusting to the sudden intrusion with staggering speed, she composed herself, giggled, and started bouncing on his cock. The physical sensation of her silken depths stroking his length, while her pucker milked the root of his shaft, was just as pleasant as the sight and sound of her. Her look was stunning, the delicate moans and hushed whimpers which passed her pouting lips were a siren’s song, and her delicate fragrance was ambrosial. In every way, right down to her little package, she was perfect, and he wouldn’t change a thing about her.

Watching the imprint of his stallionhood disappear and reappear within her abdomen, periodically glancing up at her bliss-wracked face, his virile inclination to conquer steadily gained strength. Taking a passive roll was all well and good, especially if or when he was feeling exhausted, yet his instincts begged for him to take charge. Extending his wings to either side of her, he clutched her shoulders and increased her pace.

“D…Daddy,” she sputtered, hammering her ass on him.

Lifting his head, he pulled her in. “Does my Baby Girl want me to be rough?”

Rumble nodded eagerly, giving the dick lodged in her backside a particularly forceful squeeze. “Yes, Daddy, please…”

“Then give Daddy some sugar,” he purred.

Changing her positioning would mean giving up what little control she had, but seeing him pucker his lips demanded she act. Draping her slender torso over his chest, continuing to roll her hips back to work his cock, she wrapped her forelegs around his neck and kissed him. His tongue wormed into her mouth, crowding her muzzle and sending a thrilled shiver up his spine, as he hammered into her from below.

If she had to name one thing she loved most about Thunder, it was just how passionate he could be. He didn’t merely treat her like a sex object, he treated her like an honest to goodness wife. Over the last few months, since she’d returned home with him, he’d bought her simple dresses, accessories, makeup, and even an evening gown; while the attire wasn’t nearly as showy or salacious as the outfits she’d worn in Hoity’s shop, something about the simplicity of them, of being turned into a homemaker, made her heart swell.

Hotly making out with him, as he gradually plowed her harder and harder, her thoughts wandered. Wild imaginings of herself standing at an altar, wearing a wedding dress, while watching him talk down the aisle in a tuxedo sent her skyrocketing toward release. It was all well and good to be his lover, but to be his wife was the thing dreams were made of. Twisting her head to the side, she brought her muzzle to his ear.

“Harder, Daddy,” she breathed, nibbling his ear.

Grabbing her ample hips, Thunder propped himself on his wings and took control. Stars above, he could have kicked himself for not claiming her sooner. Beyond the astoundingly good sex, she genuinely cared for him. She’d worry if he was late, took care to pack his lunches when he was away for a day, and she kept the house absolutely immaculate. Though he’d initially assumed she’d be a lewd, hedonistic plaything, she’d turned into something all the more captivating - a lover beyond peer.

Every unstoppable thrust drove her small body upward, as his raging libido took charge. Her feminine moans, the slapping of his balls against her supple tush, his resonant grunts, and the drumbeat of their colliding bodies coalesced into a depraved symphony, driving him onward and testing the limits of his endurance. He didn’t care who she was or what she’d done in the past - since he’d gotten her home, she was his and his alone.

Her backdoor fought every backstroke, being pulled out while tightly gripping his length before he drove back into her, while the speed and force of his plunges grew increasingly intense. He could practically sense how badly she needed him, how much she adored his harsh ministrations, and knowing she enjoyed it made the experience all the more wondrous. Guided by feel alone, he used his medial ring to crush her tender p-spot.

The tremble in her thighs, her hitched breaths, and the heightened pitch of her groans told him everything he needed to know - she was getting close. Even before he’d ended up with her, he’d taken profound joy from getting his lovers off, ensuring that they relished the experience just as much as he did, and she was no different. Resting his head on her shoulder, he folded his wings round her back and held her close.

“You getting close?” he muttered.

“Mm - Ahn - mmhmm,” she unsteadily hummed.

Kneading her ass with his forehooves, he decided it was time to sink the final nail in her coffin. “Good…”

Before she could reply, he flew into a frenzy. Like some great machine, using his substantial muscle and every bit of his strength, he jackhammered her from below. Though he could have taken his time and made her cum later, saving his stamina while drawing out the event, he saw no need to hold himself back. She wasn’t going anywhere, nor did he have any plans on leaving her, and he knew there’d be plenty of chances to rut her in the future.

With her eyes rolling to the back of her head, Rumble’s composure broke. Even if she’d tried to hold herself back, there was no stopping the inevitable. Thunder was superior to her in every conceivable way, and if the titan wished for her to cum, she was going to cum - it was as simple as that. Throwing her head back, shivering from hoof to head, the dam of overwhelming rapture burst.

Thin seed gushed from her colthood, painting her stud’s toned belly, as her pucker spasmed wildly around his throbbing length. The pleasure surging through her was as indescribably potent as ever, threatening to eclipse her sanity, yet she endured - not for some self-serving purpose, but because that moment brought with it a stunning realization. Though she fawned over him and did everything she could to ensure he was happy, there was one thing she hadn’t confessed.

Fighting through the ecstasy, she drew a breath, pushed herself back, and peered down into his amber eyes. “I love you!” she howled, finally giving voice to what she’d felt for far too long.

Thunder’s pupils shrank to pinpricks, his heart felt like it may explode, and his stallionhood pulsed and flared, as her admission rang in his ears. Somehow, for some unfathomable reason, her confession resonated within him, striking a chord he didn’t know he had, and it thrust him over the edge. As his length pulsed wildly, with the tip of his shaft swelling and locking into her depths, he slipped past the pearly gates of Nirvana.

Rich, thick foal-batter coursed through his cock, erupting like a geyser in his little lover. His profound size and superb health had always made him exceptionally productive; whereas most stallions could give a good few shots of creamy essence, his output was more like a raging torrent that ebbed and flowed. Lost to his rapture, he pulled his head back and bit down on his mate’s neck.

He wasn’t sure if it was from the tinge of pain or the monumental influx of jizz, but Rumble’s climax redoubled in power. Howling to the heavens, the lithe femcolt all but convulsed atop him, doubling his own pleasure in the process. It wasn’t like he’d wanted to hurt her in the slightest, but his stallionly compulsion to mark her as his own was too much to bear. Breeding her like the fertile mare she was at her core, he pumped his seed into her.

Slowly but surely, though neither could see it, Rumble’s belly gurgled and swelled. The sheer quantity of Thunder’s jizz was beyond reproach, rounding her stomach and making her appear exquisitely gravid. As their bliss gradually subsided, replaced by the euphoric afterglow of their near-tandem orgasms, they reared back and gazed at one another.

“I love you too, Babe,” Thunder hummed, fondly stroking her neck.

Rumble wearily beamed and eased herself down, savoring the warmth, comfort, and protection he afforded. She couldn’t say what she’d done to deserve such a peerless stud, but she issued a silent thanks to the heavens they’d made the switch from siblings to paramours. No matter what obstacles they faced in the future, she felt certain that everything would turn out alright for the both of them…
