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…
