"...When they say 'fifth leg,' it's not hyperbole."

"Oh! Goodness..."

Big Mac heard scraps of the conversation as he passed by Sugarcube Corner. He didn't know what had prompted Carrot Top to gossip about him with Mrs. Cake, but they were watching him stroll by with fixed gazes, Mrs. Cake blushing and trying to hide her excited grin. He gave the mares a polite smile, as if he hadn't heard them, and he watched them smile and wave back. Then, he gave them a wink. Mrs. Cake erupted into a fit of nervous giggles before heading inside. Carrot Top followed her, but not without one last lingering look. Big Mac merely continued down the street, chuckling to himself.

He was used to it.

"How's it hanging Big Mac?" Caramel asked him, giving him a friendly elbow as he walked by him on the street.

"Hey there, farm stud," Nurse Redheart said with lidded eyes from a market stall.

"Oh! Big Macintosh," the spa twins approached him on the street. Aloe, the pink one had addressed. "If you aren't busy, you should come inside and let us give you another deep tissue massage again," she said, batting her eyes at him.

The blue one, lotus, rubbed her hoof in his broad chest. "Oh yes. We know how swollen and stiff you can get. Won't you stop by later?"

"Eeyup," Big Mac answered in a husky voice with a waggle of his eyebrows. The two spa mares giggled, but let him go on his way.

No, it definitely wasn't a secret.

Most ponies didn't know that his birth name was just Macintosh. And when he told others, they often didn't believe him. But it was true. He didn't get the name "Big Mac" until shortly after puberty hit him like a ton of bricks. He sprang right up, tall and getting taller, putting on weight fast, and he had the hormones to match. When he was fifteen, before he had thought to listen more and speak less, it hadn't been hard to sweet-talk Junebug into losing their virginities together out in the old barn. Mac told a few of his friends, but Junebug told everypony, especially about how impressive he was where it counted. When he came to class the following Monday, everypony was calling him Big Mac. He didn't know whether to be embarrassed or proud, but soon even the teacher began calling him Big Mac, unwittingly at first. Once word got around, Big Mac began to receive a lot of requests from the other fillies to see the old barn, as well as invites to dances and sleepovers. By the time he was a full-grown stallion, everypony knew one way or another why he was called Big Mac, and the name had stuck ever since.

Not that Big Mac minded. Most ponies had enough sense to use a little tact when talking to him out in the open, especially around his family. But he'd be lying if he said he didn't like the attention. What stallion in their right minds wouldn't? Big Mac might not have cared much for talking, and he knew that one day he wanted to find that special somepony, probably a mare involved in food service, and fall in love properly, but he was still a hot-blooded male in his prime, after all. His not-so-little reputation had landed him more tail than he could remember, and with each tail he landed his reputation only grew. And it looked like his sizeable friend had just landed him a three-way with the spa girls again.

Big Mac had to admit, it was good being hung. And Big Mac was very, very hung.

Normally, he would have followed the spa girls inside and rutted them senseless, but he did have a job to do today, and their rumps weren't going anywhere. As Ponyville's premier handystallion, whenever he wasn't busy bucking apples, hauling apples, or slapping mares' rumps with his own apples, he earned a modest bit of extra pocket change by fixing roofs, windows, floors, pipes, hips; whatever was broken, he could fix it with whatever was in his trusty tool belt. While it was hard to resist the offer of the spa mares, and even harder to stay in his sheath at the thought of what they had in mind for him, his Pa had taught him well that work always came before pleasure.

So, following the Ponyville river and crossing the bridge outside of town, Big Mac arrived at Fluttershy's cottage to fix her leaky roof.

The shy pegasus was already outside watering her flowers when he arrived. Fluttershy was almost too sweet to find attractive, caring for every creature she met with warm, nurturing love. But it was undeniable that she was cute. Gorgeous even. Long-legged and thin, yet proportioned just right in the flanks, plus those big eyes and long mane, and soft wings were highlights of their own. Fluttershy was nice, but she was definitely a nice piece of eye candy to a stallion as well.

Big Mac didn't say anything as he approached. He didn't want to startle her. But when his shadow passed over her, she looked up and yelped. Big Mac didn't have a threatening face in the slightest, but he was tall and broad and burly. He supposed he really couldn't help frightening her.

"Oh, goodness," Fluttershy said, placing her hoof to her beating heart. "Sorry, Big Mac. I didn't hear you arrive. You've come to fix the roof?"

"Eeyup."

"Oh, thank you. It's very kind of... a big, strong stallion like yourself to... help out a little mare like me." Fluttershy said, hiding behind her mane but still blushing at him.

Big Mac raised a brow, but only replied, "Eeyup."

"Here. Let me get the ladder." Fluttershy floated inside, and Big Mac followed her. She went rummaging around in a closet as a horde of rodents and woodland creatures big and small watched her. She turned an eye back toward Big Mac. "It's just back here..." she said, reaching in further, arching her back and swishing her tail a bit. Big Mac raised his brow again.

She began to pull a big wooden ladder out from the closet, but even holding it in two hooves she began to totter with the ungainly weight of it. Big Mac stepped up to steady her with a hoof before taking the ladder in one of his, holding it over his shoulder with ease.

Fluttershy straightened her mane and smiled at him, blinking sweetly. "Oh, thank you. And look at those muscles! They really are... impressive." Again, she hid behind her mane, and Big Mac raised a brow.

He didn't respond, only offering an easygoing smile as he headed outside with the ladder in tow. Fluttershy followed him and watched him as he set it against the side of her house. "Here, I can steady it at least," Fluttershy said, ducking beneath the ladder to hold it with both of her hooves. Big Mac just nodded.

He began to ascend the ladder slowly. He could feel Fluttershy watching him, sure as there was sunshine. He looked down and her eyes were fixed on his body. Yep, she was definitely checking out his balls. It seemed she was totally oblivious to his noticing of her staring, but Big Mac just had to grin and shake his head a little. He made sure to take the ladder extra slow, raising one leg nice and high and letting it linger, giving the shy pegasus a good view of his heavy sack hanging low between his thighs. When he had climbed onto the roof, he hopped up with both hindlegs and crouched, letting his fat nuts dangle over the edge a bit. Fluttershy gasped, and he stood up, chuckling quietly to himself.

It was clear what the problem was. A recent storm had brought a big tree branch crashing down on Fluttershy's cottage, knocking a big hole in the foundation of the roof that supported all the other carefully-arranged branches to give the appearance of a tree. It would be a simple fix. Gripping his trusty hammer in his teeth, Big Mac set to work.

He had fixed so many roofs in his life, it was easy to let his mind wander. He supposed it was a little teasing to show off for Fluttershy the way that he did, but he doubted it had done any harm. Plenty of mares gawked and stared as they tried to get a look at his bits, even mares he would never bed without stirring up quite a bit of trouble. If a mare couldn't get a look at his pride, getting a look at the Apple family jewels was definitely the next best thing. Big Mac didn't mind. They were too big to keep covered all the time, and by now he just accepted that any pony standing behind him would get to see at least a little bit of sack. And sometimes he would swish his tail aside while walking down the street to give a mare a good look at his plump apples. He wagered it was much appreciated when those mares fantasized later on about his nuts slapping hard against their flanks.

He supposed he was a bit surprised to catch Fluttershy gawking, though. She didn't seem the type, but then again, he supposed a stranger might not think quiet, unassuming Big Macintosh could be Ponyville's top stud. He couldn't quite be sure what she was getting at though. Big Mac had bedded a lot of mares, but he had always stayed away from Applejack's little friends. The last thing he wanted was to upset his sister just to get his rocks off. He was certain they knew of his reputation; everypony did, but he had always been polite with them, and they had never directly approached him about it. Big Mac imagined poor Fluttershy was likely in the same boat as him; passingly curious about the rumors, but not really willing to risk complicating her relationship with Applejack to find out the truth. At least, until the opportunity was dangling right in front of her muzzle from between his thighs.

Well, he hoped she had gotten her fill. The roof was finished with still plenty of time left in the day, and Big Mac had only worked up a light sweat to boot. He climbed down the ladder and headed back inside. Fluttershy awaited him with a glass of cold lemonade, and he informed her the job was done.

As he gulped down his refreshing beverage, she said, "Oh, thank you so much. You got it done so quickly, too! Here, let me get your payment."

Big Mac set down the glass as Fluttershy dug through a satchel on the kitchen table for a hooful of bits. But she came up with a concerned expression on her face. "Oh, no! It seems I don't have any money!" she said, much louder than her usual tone of voice. She turned back to Big Mac, lowering her head and gazing up at him with her sweet doe eyes. "But such a... big, strong, handsome stallion like you deserves payment. Is there, uh... anything else I could do to repay you?"

Big Mac grinned. Mares had run out of money to pay for his work enough times that he knew exactly what was going on. "Eeyup," he said.

He decided not to play coy with her; it was clear Fluttershy was aching to see the goods. He trotted up to her and reared up, planting his forehooves heavily on her kitchen table. Then, his namesake flopped out of his sheath.

"Oh my goodness!" Fluttershy gasped. The sound of cock-shock was music to Big Mac's ears. Even soft, his dick was long enough to reach the flooboards, his flare grazing the wood below, and thick as Fluttershy's foreleg. He gave her a few moments to take in the sight, to overcome the disbelief. Most mares needed some time to process after first seeing it. "The spa ponies weren't kidding..."

"Eeyup," Big Mac said boastfully.

The attention was already helping Big Mac to stiffen up, but after the initial shock, Fluttershy was eager to see him at full mast. "Can I...?" she asked quietly.

"Eeyup." He flexed, his dick smacking against his belly with a heavy thud for emphasis.

Fluttershy approached and gingerly reached her hooves out to stroke them across Big Mac's meaty length. His dick gave another throb as heat and blood rushed to it, and Fluttershy explored it, running her hooves across the entire piece as it slowly stiffened. "Wow..." she said softly. "I heard it was big, but I didn't think it would be this big... Does it hurt when you...?"

"Nope," Big Mac replied confidently. Usually all a mare needed was a few moments to adjust to their insides being rearranged around his massive pole, but once they got comfortable, he had received nothing but praise.

Fluttershy continued to rub his member with awe as it throbbed to life before standing proudly on its own beneath his belly. Big Mac snorted, content to feel the beginning tingles of pleasure run through his loins, but eager for the main event. Fluttershy eventually asked, "H-How do you...?"

Big Mac merely made a twirling motion with his hoof. Fluttershy nodded with understanding. "Oh! You mean, like this...?" she asked, turning around until she was facing away from Big Mac. Then, with a blush on her cheeks, she crouched down, lifting her tail and raising her rump a bit for him. Beneath that strawberry tail, Big Mac could see her buttery lips, her hot, swollen pussy drooling needy juices around her cheeks and thighs. "I'm ready..." she said. And Big Mac could see that she was definitely ready.

Big Mac knew some mares liked foreplay. They wanted to flirt and kiss and tease all night before they'd lift their tails for you. But Big Mac wasn't that kind of stallion. And for most mares, just getting to witness his monster cock was more than enough to leave their nethers soaking wet and ready to be stuffed. Fluttershy was no different. So with an easygoing pace, like he had all the time in the world, Big Mac approached that offered rump with a cocky grin, his cock throbbing stiff below him.

He reared up on his hindlegs and mounted, landing heavily on Fluttershy's back. Then he lined up his broad flare with her moist entrance, and when he felt the waves of heat emanating off her lips, he thrust forward.

"Ohhhhh!" Fluttershy's moan rang out through her cottage, sending several animals scurrying. She was fighting to catch her breath as Big Mac's massive cock sank into her with a wet squelch. She had never felt so full in her life, her pussy stretched to its limits, like Big Mac might tear her in half! Fluttershy was on the verge of pain, but she felt a firm warmth spread through her body, shivers running down her spine. Big Mac felt so very deep inside of her. When she could speak, she asked, "Is that... all of it?"

"Nope," Big Mac answered confidently. Then he thrust again, and Fluttershy let out another guttural moan as more and more of that meat slammed into her.

Fluttershy's pussy swallowed it all, gaping to accommodate the huge girth and the even more staggering length, more than she thought she could ever fit inside of her. She felt like she could feel his cockhead in her throat, and every throb of his shaft made her wings twitch and her clit burn. It was the biggest thing she had ever felt, and she was certain no other stallion in Equestria could wield a bigger dick. Certainly no mare in Equestria could take more. "Oh my goodness..." she groaned. "I can't believe you got it all inside of me."

"Nope," Big Mac said again.

Fluttershy's eyes went wide as she felt another thrust slam into her, inch after inch after inch sliding into her soaking wet pussy, filling her beyond what she thought was her limit, stretching her out completely around his massive stallionhood, more and more and more until she thought she couldn't take another inch. Then, she felt his big, heavy, firm balls against her thighs and clit, each orb its own heavy weight against her backside, and she knew she had taken all of Big Mac's legendary big dick. She couldn't even begin to imagine how big it was, but she was certain it would be more prudent to measure in feet rather than inches. When her breath returned, she was still reeling in pleasure and shock, and all she could manage to squeak out was a tiny, "Holy shit."

That was what Big Mac loved to hear. He knew his dick always felt twice as big as it looked. And it looked really fucking big to begin with. Most mares on their first time with him just couldn't adequately prepare for what the experience was like. How could they? He was double the size of even the other stallions considered to be prodigiously endowed, let alone triple or even quadruple the size of an average stallion. Getting fucked by him almost didn't qualify as sex; taking his cock was an experience that was just on another level completely.

But he was inside Fluttershy now, and no amount of waiting would ever help a mare's pussy adjust to his battering-ram cock. So Big Mac started to ride her. He withdrew his hips, removing nearly half of his cock, but that was enough to leave Fluttershy feeling the gaping absence of his meat inside of her. He thrust back in with his hardy farmer's muscles, bucking into Fluttershy powerfully, a wet and loud smack echoing through her cottage as his hips and balls collided with her rump. Fluttershy could only cry out with pleasure, completely at Big Mac's mercy as he began to set a slow but strong pace with her.

He made sure she could feel the inches slamming into her with each thrust, and he relished the way her soft cheeks rippled when they met his hips. From the way her yelps of pleasure bounced off the walls of her cottage, it was clear she was enjoying herself. The sheer size of his dick guaranteed that he was hitting her g-spot, her clit, and whatever other sweet spots she might have had all at the same time, and if that wasn't enough, then his wrecking-ball nuts slapping into her clit with each buck into her was certain to bring her to new heights of pleasure. At least, it sounded like she was having a good time. Big Mac had never heard her be so loud before. "Oh, Big Mac! Big Mac, yes! Ohhh, Big Mac! Big Mac!!!" she screamed as her felt her body shudder and spasm beneath him.

Big Mac grinned, but didn't slow down his pace for a moment. He hadn't been fucking her for more than a few moments before she was already having her first orgasm. Although, that was common for Big Mac. He knew it wouldn't be much longer before she had her second. Then her third...

The farm stud was truly in his element now, and his true special gift was coming to bear. Not only did Big Mac have a terrifically huge cock, but he knew how to use it, too.

As he slammed into Fluttershy, each pound of his staggering cock knocking the wind out of her, Big Mac had to admit that she felt pretty good too. Nice and soft, and her trembling legs and slender frame only made it easier to hold her down and fuck her brains out. Soon, her forelegs buckled, but Big Mac wasn't about to stop. In fact, the angle only allowed him to reach deeper into her, and he grunted and whinnied in pleasure as her passages clenched around him with her next climax, trying to milk him of his load. With each surge of his hips, he felt like he was going to pound her into a crater on her own floor, but he couldn't deny how good it felt. The heat of her body, the desperate moans from her lips, and her frail body beneath his powerful form all sent his ego surging even more. Fucking a mare always made his balls feel a little bigger. But giving a mare sex she'd never forget was a testosterone high Big Mac lived for.

After her third - fourth? Big Mac wasn't keeping count - climax, Fluttershy could hardly form sentences. Pinned beneath his strong barrel chest, she wailed for him. "Big Mac! Ohh! Please-!"

She didn't have to say it. Big Mac knew exactly what she wanted. He hadn't been on top of her for very long, but Big Mac was accustomed to cumming whenever he pleased. Usually mares were plenty satisfied by then. And he could already feel his cock throbbing. He picked up the pace, fucking her hard and fast, his mighty hips a red blur as he sank his cock deep inside of her, a giant meat piston that slammed Fluttershy's pussy to the core.

"Please!" she begged on. "Won't you- Won't you cum in me?" she asked, her face bright red as she finally spit her words out.

Big Mac grinned. He didn't expect such a naughty request from the shy mare, but he had no intentions of pulling out now. "Eeyup!" he answered proudly. He could already feel his cock throbbing inside of her, his balls tightening, poised to blast her pussy with thick, steamy cum. He kept thrusting, pleasure surging through his muscles, sweat beading his forehead, eager to unload inside of this mare and fill her to the brim with hot Apple seed.

It didn't take long. Moments after he gave his word, he planted balls-deep inside of her, his sack throbbing against her clit and her pussy stretched wide around his base, his stallionhood buried deep, deep within her belly. He gave a rough grunt as he felt the first burst of cum fill her. It was a sensation he would never tire of; fucking the hell out of a mare and jizzing deep inside, his essence stuffing her full and flowing back around his massive dick. Fluttershy wailed in one final climax below him, her hooves wrapped around his firmly planted on the floor, her pussy winking against his sack, as if her body itself was begging for every last drop.

When it was over, Big Mac gave a long, satisfied sigh as he began to pull out. He had to take steps backward to get it all, and soon his heroic, half-hard meat popped free from her pussy with a splatter of cum, his dark shaft stained with a white coating of his essence. It would be a while before it retreated back to its sheath, but Big Mac was content to let his junk buzz for a while longer. He wore an easygoing grin on his face. He always did after getting some tail.

Fluttershy lay there on the floor, her body racked by occasional spasms and jolts of post-orgasmic pleasure, but soon her faculties returned to her. She didn't move, her legs still far too wobbly, but she did look back and blush at Big Mac. "Thank you," she said softly. She even offered a slight smile herself. "All in a day's work, right?"

"Eeyup," Big Mac answered. He stepped past her toward the door, giving her flanks a playful pat on the way out. If it was later in the evening, he would have stayed and cuddled, relishing in her praise. But in the middle of the day like this, he was a busy stallion, and he knew he would be seeing Fluttershy around Ponyville much more often.

All in all, the encounter hadn't taken too long. Maybe an hour, give or take fifteen minutes. By the time he was back downtown, his cock had retreated into its sheath. It was still bright and sunny as he headed through Ponyville out to Sweet Apple Acres to finish his farm work for the day. And just as before, he collected greetings from ponies on the street, just as he did every day.

"Hey Big Mac," Cheerilee called to him while batting her eyes.

Junebug bumped her rump against him as she passed by. "There's my favorite stud," she teased as she passed by, even lifting her tail a little bit as he turned to look at her.

Thunderlane waved. "Hey, I know that grin!" he said, growing his own big smile. "You just banged a mare, didn't you?"

"Eeyup," Big Mac confirmed as he gave Thunderlane a hoof bump.

Thunderlane just chuckled and shook his head. "Man, you are so lucky. I wish I got half the action you did!"

Big Mac was a stallion of his word, though. When he walked into the Ponyville Spa, Aloe and Lotus's faces lit up at the sight of him. "Oh! Mr. Big Mac! Please come in!" Aloe greeted him.

Lotus batted her eyes at him with a flirty smile. "Here for your deep tissue massage?" they asked.

"Eeyup."

Within minutes, Big Mac was lying back on a massage table, his forehooves behind his head and his hindlegs spread wide while the twins fondled and massaged his big package. His towering cock rose before them, and the two cooed and gasped at it. "My my! It always looks more impressive than I remember," Aloe said.

"And that smell... You've been working hard all day, haven't you?" Lotus asked, still smelling Fluttershy's pussy and his stale cum on his shaft. "Let us clean you up before your massage."

"It's our pleasure," Aloe added. Then, the two mares plastered their tongues to his throbbing meat, slowly licking over every inch and rubbing his dick back to a vigorous and firm erection, as if Fluttershy had never happened. He groaned, feeling their worshipful kisses and long licks up and up and up his shaft, from base to tip, all while basking in their compliments.

"It's so big..."

"What a stud you are..."

"I want your huge cock so badly..."

Eeyup. Big Mac had to admit, it was good being hung. And Big Mac was very, very hung.
