Day 1: Ensemble
Macintosh sniffed the top of his sister’s tail. Her sweet apple scent had a hot, intoxicating tinge to it today, like the taste of a shot of whiskey.
“Really?” he rumbled.
Applejack lay on Igneous and Cloudy’s bed facing away from him tail up and hind legs out straight behind, the posture brazenly inviting. Normally he wouldn’t hesitate to plow his sister’s field, morning, noon, or night. Morning, noon, and night, even on somepony else’s bed, and even with Apple Bloom and the Pie sisters playing board games in the next room. That Apple family ass, striated with muscle from kickin’ trees all day and layered with soft fat from apple pies, just begged to be fucked raw.
Except that Applejack was in an unseasonable winter heat and they hadn’t brought any condoms when they’d come to the Pie farm.
Applejack didn’t care. “Why don’t you put a foal in me? I always wanted to be a mom. And it’s not like my dating life is going anywhere. C’mon. It’ll be fun.”
“Won’t be fun to have an incest baby,” rumbled Macintosh.
“Aw, don’t be an old stick in the mud,” said Applejack. “We’ll tell it the father was a passing stranger. Mysterious and handsome. Nopony ever needs to know.” She flexed one buttock, and then the other. Mac watched the muscles bunch and unbunch in fascination. His cock, already so hard it hurt, twitched violently. He wanted his sister, needed to bury his cock between those fat cheeks. But he really shouldn’t. It was a bad idea.
“Tell me you don’t wanna be a daddy,” purred Applejack. Her pussy dripped with pungent mare goo, pooling up on Igneous and Cloudy’s sheets. Harmony damn it, they were gonna have to wash those now.
“Favorite uncle, you mean,” rumbled Macintosh. He would like a foal or two. They could help on the farm, carry on the family name, play hoofball with him, that kinda thing. But somehow the mares didn’t tend to stick around when they found out that you had a non-negotiable siblings-with-benefits thing going on on the side. Mighty unreasonable of them; had they even looked at Applejack’s ass?
Applejack groaned and buried her face in the straw-filled pillows, squashing the crown of her hat. “Oh, you can be whatever you want! Just put it in me! I need it!”
Macintosh shook his head. “No. You’re in heat. I gotta be the responsible one.”
Applejack looked over her shoulder at him. Her big green eyes narrowed seductively. “Tell you what. You eat my pussy. Once I’ve cum, I’ll be able to think more clearly, and I’ll see you gettin’ me pregnant is a bad idea, and we’ll go back to the living room and Marble can deal us into whatever crazy-ass boardgame she dragged out this time.”
Macintosh bit his lower lip. “But once you’ve cum, I’m gonna wanna cum.”
“You can fuck me up the ass. You can’t get my ass pregnant.” She straightened out her hind legs and lifted her sweet butt up to him. The cheeks squished up against his snout; ponut in front of his nose, silky orange pussy lips against his mouth. He scooted backward, the bed creaking under his weight.
“I can’t… it won’t… Do we even have any lube?”
“Nope.” She smiled smugly, and winked her pussy at him, showing him the glistening soft pinkness inside.
Macintosh leaned forward. He couldn’t stop himself; that apple whiskey smell was just too lush. He ran his tongue over his sister’s lips, scooping up apple goo and rolling it around in his mouth.
“That’s right… that’s right…” purred Applejack. “Just like that.”
Macintosh slurped his sister’s pussy from bottom to top and she squeaked happily. He nuzzled his huge blunt snout against the opening and lapped sweetly at her little double nub. The lick made her buck up off the bed so he grabbed her ass cheeks to hold her still. His hooves dug into her flesh and he tugged to either side, pulling her pussy wide open. He slid his tongue inside — even after fucking it a million times with his monster cock, her pussy was still a tight fit for his tongue. He wanted to pull his tongue out and jam his dick in, but no, getting one of your little sisters pregnant was a bad, bad idea. Stay strong Macintosh. Make your sister cum and help her clear her mind, and better be quick about it.
“You contemplatin’ the beauty of my foal shoot, there, big brother?” groaned Applejack. “Stop teasin’. That clit ain’t gonna lick itself.”
His sister’s coarse words sent a shiver down his spine. He pulled his tongue out of AJ’s pussy and back down to her nub. He licked it in circles, slow and firm, the way she liked. It pulsed, hot and hard under his touch.
“Oh, big brother… oooohhh sweet horny toads that feels good. Harder.”
Macintosh grinned, and grabbed his sister around the waist and pulled her into one of their favorite positions. He said up straight on his haunches. She wrapped her thick, iron-muscled thighs around his head. Her body hung straight down his with her snout at the level of his balls. A lot of times she’d impale her face on his cock when they were like this, but right now she contented herself with drooling all over his balls.
“Ain’t gonna suck itself,” muttered Macintosh between licks.
Applejack socked him in the thigh. “I thought I was gonna let you dry fuck my ass.” She sucked one of his balls into her mouth, rolling it against her tongue. Just the one ball filled almost all the space in there. It made both her cheeks bulge out like she was a chipmunk harvesting nuts.
“Harvesting nuts. Hehe.”
“What are you babbling about?” Applejack kicked him in the back of the head, and he went back to sucking. The big tendons in the backs of her thighs began to tense, just like they always did before she came. Her muscle-ribbed belly ground against the underside of his cock. Her little mouth felt warm against his balls. Normally he might try to draw out this sort of fun, but he needed to get her back quarters sorted so as to get those funny ideas about making a foal out of her front quarters. He ground her clit against her pubic bone. The fluffy fur around her pussy tickled the underside of his tongue. She twitched in his forelegs, and he groaned into her cunt. Harmony, he loved her so much. He’d tell her so, but his mouth was busy.
Applejack’s body grew more and more tense, her small but sturdy frame shaking hard against his. She moaned, her voice muffled by his ball in her mouth. He held her tight against his chest, breathing deep, inhaling her perfect scent. Her moans deepened to muffled shouts. Her legs kicked out straight, and a jet of mare goo squirted across his face.
He grinned. “Was it good for you?”
She slid off of him and balanced on her head with her ass in the air. “It was pretty gol dang incredible. But not as good as it’s gonna be when you dry anal pile driver me into oblivion.”
Macintosh stood on his hind legs and aimed his shaft down towards his sister’s butt. Pre drooled from his cock tip onto her snout; she licked it clean. “Dry anal’s damn agonizing. I don’t wanna hurt you,” he said.
Applejack smirked. “Oh, you ain’t gonna.” Suddenly her hind legs lashed out. Her hooved gripped his ass cheeks, and she pulled him forward, jamming his cock into her — not into her ass like she’s promised, but into her pussy!
“Gah! Ah!” screamed Macintosh, as his cock sank medial-ring deep into his sister’s glistening twat. “You tricked me!”
Her hind hooves dug into his ass cheeks, muscular legs flexing to pull him down into her. “You’re stronger’n me, big brother. If you don’t like it, pull out.”
Right. Pull out. He had to. For the good of ponykind, all he had to do was slide his cock out of his sister’s pussy before he came. Easy as pie, right? But his hips had a mind of their own. They bucked downwards, slamming himself deeper into her pussy, jamming her head and shoulders into the prickly straw mattress of the creaking bed. They were a tower of wicked, unnatural, joyous pony flesh, Applejack standing on her head while he plowed her fertile crescent.
“Feels… feels so good. Too good to stop,” he rumbled, craning his neck to look over his cider gut at where his cock was going into her. His fat shaft, as thick as one of her hooves, strained her pussy lips into a glorious O shape, glossy orange flesh glowing pink from being so roughly distended.
“Then don’t stop,” moaned Applejack. “I want you. I want your foal in me.”
Pearls of sweat trickled down Macintosh’s forehead. He was going to cum soon. He had to pull out. Had to. But he just couldn’t stop! She felt so soft and tight around him, silky flesh walls cradling him. He pulled back, and Applejack’s thighs tightened around his hips, pulling him down into her until his cock head slammed against her foal hatch. His balls boiled, threatening to spill over into her at any second. But he could still pull out. It wasn’t too late. Come on, just one more thrust, then he’d pull out. Cum all over her ponut; it’d be hot.
“I love you, big brother,” whimpered Applejack.
Macintosh’s eyes snapped wide open. On no. That’d done it.
His lower belly exploded with white-hot ecstasy, while his cock exploded with white, hot stallion sauce. He felt every pulse as it rippled through his fat tube and into Applejack’s punishingly tight cunt. He filled her to bursting on the first shot, but his balls just kept pumping. Seed welled up over the edges of her pussy lips and trickled down her belly onto the huge grin that split her face.
“Hello, baby daddy,” she purred, eyes dancing.
“It don’t always take,” he said, gingerly pulling out of her. It always felt so great going in, but afterward, his junk felt so hyper-sensitive that it hurt to be inside of her.
“Hey, guys!” said Pinkie Pie, sticking her head through the door of the bedroom.
Macintosh hit the ceiling and stayed there, clinging to the rafters. Applejack stayed put, big cummy grin on her face, still upside down on the bed, dripping with/full of his spunk. “Hey cuz!”
“Sorry to bother you, but: it’s snowing! Big fluffy flakes! Wanna come see?” said Pinkie, like it was perfectly normal to walk in on brother-sister incest.
“This… this ain’t what it looks like,” said Macintosh.
Applejack rolled over and pulled her hat off so she could lick some cum off the brim. “It’s exactly what it looks like.”
Pinkie rolled her eyes. “Yeah. We knew anyway. We heard you in the living room. I think ponies heard you in the next county.” She narrowed her eyes. “Heeeey, can I have some of that cum?”
“Ask Macintosh,” said Applejack. “It’s his goo.”
“C-c-cousin!” he stammered.
“Oh silly,” Pinkie waved a hoof at him. “Incest is nothing to be ashamed of. But. More importantly: it’s snowing out!. C’mon!”
✭☆✭☆✭☆✭
Macintosh stood knee-deep in fluffy fresh snow, green scarf around his neck, ruminating as his sisters and cousins frolicked. Every once in awhile a snowball would smack into his body. He ignored this. An idea was forming in his noggin; the process took a while, and he didn’t want to interrupt it.
Not an idea. More of a realization.
The realization he’d been set up.
So. Igneous and Cloudy had gone away for a week, allegedly to visit an ailing relative in Zebraica. For some reason the rock farm needed to be fully staffed in the middle of winter, so he and AJ and Apple Bloom had come down to help. Okay. He hadn’t questioned that. Questioning things wasn’t his forte. So now he was here, with his four young-but-single-and-not-getting-any-younger female cousins. All of whom were in heat — he’d allowed himself a discrete sniff of every butt in the house while they were getting their winter things on, and he was sure of it. As was freshly cutie-marked and barely legal little Apple Bloom. Winter heat in one pony was a very rare occurrence. In a whole houseful of mares? It boggled the mind. Unless they’d all taken fertility potions.
Granny Smith often made comments that she’d like to see the next generation of Apples get started before she passed on. And Macintosh’d bet his right nut the Pie parents were getting desperate for grandfoals as well. So desperate that maybe it didn’t matter to them who sired those foals. If they’d heard that Macintosh could cum buckets several times a day, every day… which Applejack could’ve told them…
His eyes grew wide. It was a conspiracy. These mares wanted him to get all of them pregnant! Damn, they could’ve just asked.
A snowball whacked him in the nose.
“Come on, big brother!” said Apple Bloom, packing another snowball together with her hooves. “Play with us!”
Macintosh sighed. He guessed he was going to.
All week long.
He couldn’t say he wasn’t looking forward to it.
✭☆✭☆✭☆✭
“Eat your damn quinoa,” growled Limestone. “You’re going to need all the protein you can get.”
Macintosh sniffed at his bowl. He liked quinoa fine if it was cooked it right, but this was made Pie family style — plain as folk and bland as glue. Who’d made this crap? Why wasn’t Pinkie doing the cooking? “You all aren’t going to be at all subtle about this, are you?”
Limestone glared at him. “We don’t need to be subtle, with six hooves of snow on the ground. You just try and make it to the train station.”
"Lime, don't be cruel," said Maud. "He doesn't have to play if he doesn't want to."
This snowstorm was very convenient for them, wasn’t it? It was almost as if they knew somepony with contacts in the Equestrian Weather Service. How deep did this conspiracy go?
Across the table from him, Marble rolled her empty bowl onto its edge and licked the rim in what Mac guessed was supposed to be a salacious gesture. Instead, it just looked like she had terrible table manners. Pinkie and Maud sat to either side of her, Pinkie grinning and Maud impassive, as he would expect.
His cock twitched under the table. Bad cock. He shouldn’t be into this. Sure, he was terrified for his life — but only from sexual exhaustion. He was so used to banging his sister that knocking up distant cousins seemed like transgressive sexuality light. He wouldn’t even mind if he had to take care of the foals. He could always use more help on the farm. There was only one thing that bothered him.
“Apple Bloom?”
“Yeah, Big Brother?” She looked up from shoveling her second helping of quinoa into her face.
“Ain’t you a little young to get pregnant?”
“Oh, don’t worry about me. Twilight put me on so many birth control spells she says I could cause spontaneous abortions.” She bent down and tucked back into her quinoa.
“Please don’t,” muttered Limestone.
Macintosh blinked. Twilight. Damn. The conspiracy went all the way to the top.
“Oh, I’m sure she was just exaggeratin’,” said Apple Bloom, wiping quinoa off her chin. She tilted her head to one side. “At least… I think she was?”
Macintosh’s heart felt like it was going to pound its way out of his chest. Was it because he was concerned for his newly adult little sister’s alleged innocence? Or because he wanted to bang the living daylights out of his newly adult little sister? Or both. “Then what are you here for?”
“Oh, just to help out. Washing, cleaning, cooking, fetching water and potions, fluffing, just keeping you all happy and making ponies until this snow clears.”
Macintosh narrowed his eyes. “Fluffing? Fluffing pillows?”
Apple Bloom grinned and blushed. “No. Fluffing you. I know we ain’t never been together, but… you know, I’d like to.”
Macintosh’s throat felt dry. The blood drained from his head, all of it going to his other head.
Apple Bloom misinterpreted his silence and waved her hooves in front of herself. “I mean, if you don’t wanna, I understand. I can just walk around being young and sexy and keeping you hydrated if that’s what you need to stay hard. And we’ve got plenty of potions if you start to run dry!”
“Of course I want to,” said Macintosh. “Just didn’t think you wanted to. I’m almost old enough to be your dad.”
Apple Bloom put her head on her hooves and smiled a slow sweet smile at him. “So you want me to call you daddy?”
The table went crazy. Applejack laughed fit to bust a gut. Limestone cackled cruelly. Pinkie cheered. Marble smirked. Maud nodded slightly.
“You wanna help me demonstrate Macintosh for our cousins, Little Sister?” said Applejack, wiping her eyes.
Apple Bloom pushed her chair out, hopped onto the table, and cantered over to worm her way into Macintosh’s lap between his cider gut and his cock. Macintosh’s eyes bulged almost out of his head. Her tummy and chest and thighs felt so soft against him that he felt like he could pop right there. He gritted his teeth; he didn’t want to cum early and embarrass himself in front of his family.
“Would I!” she said, looking at the massive dark mauve shaft poking out between her trim young thighs. Sweet mother of the night it was longer than her torso. “What do I do?”
Applejack rolled her eyes. “Well, first get out in the middle of the floor where everypony can see you. You too, Macintosh.”
Apple Bloom bounced off the table, jumped to the middle of the floor, and skidded around in a circle so she was sitting on her haunches facing all of them sideways. Macintosh got up from the table and followed her. Applejack smacked him on the haunch tight behind the cutie mark. “You see this, ladies? This is Macintosh’s cutie mark. Do any of you ladies know what this symbolizes?”
Pinkie waved her hoof in the air. “Oh! Oh! I know! I know! Pick me!”
“All right, Pinkie what do you think?”
“That he’s good at growing apples!”
Applejack smirked. “That’s the family-friendly version. And it’s true, after a manner of speaking. See how this big apple is cut in half, so you can see the seeds inside?” She stroked his ass down the line of the main muscle and caressed his balls. His tail flagged up instinctively. “The seeds are his cum. My brother here’s a breeding stud. A natural father. A dairy cow of dick juice.”
Limestone crossed her forelegs over her chest, leaned back in her chair, and closed her eyes. “Yeah, we all know what to do with a stallion.”
“Be quiet, Lime. I want to watch this,” said Maud, leaning forward, head in her forehooves. Marble nodded fiercely in agreement.
“But if yall wanna get the most cum out of him,” said Applejack, “you can’t just flop down and spread your legs. Macintosh ain’t like other stallions. He’s sensetive.”
Macintosh flicked his tail irritably. “I am so like other stallions.”
“Shut up and kiss your little sister.”
Macintosh sighed, blew his hair our of his eyes, and looked down at Apple Bloom, who was staring up at him with stars in her eyes. He smiled down at her and brushed his lips against hers. Their breath mingled. He brushed her lips with his tongue, and she opened her trembling young mouth for him. He caressed the inside from tongue-tip to tonsils, feeling her blissful sighs reverberate through her jawbone. She raised both forehooves to his cheeks, and he put one hoof on hers, holding her there.
“Oh, it’s so cute and romantic!” gasped Pinkie.
“They love each other so much,” said Maud.
Limestone made gagging noises.
Applejack rubbed Macintosh’s balls affectionately like she was tousling Winona’s headfur. “Now like I said: he’s a sensitive soul. You gotta take your time. No rushing him. But since this is just a demonstration — Apple Bloom! Get under your brother!”
“Yes, sis!” Apple Bloom broke the kiss so quickly Macintosh kept kissing empty air for a second and a half before he opened his eyes to see where she was. Where she was, was wrapping her lips around his cock. He dropped his head down between his forelegs, trying to get a look at what was going on down there, but all he could see was the back half of his little sister sticking out from between his forelegs. Unsure what else to do, he licked back and forth across the top of her croup. Ass muscles stood in sharp definition under her fine-furred yellow coat; he traced the outlines with his tongue.
“Being a red-blooded, all-Equestrian male, there’s nothing Macintosh loves than a good blowjob.” Applejack ran her hooves up and down the part of his cock that wasn’t in Apple Bloom’s mouth — which was almost all of it. Apple Bloom getting even that much in her face was a miracle given her lack of experience. But then, how experienced was she? She sure didn’t act like this was her first rodeo.
“I know suckin’ something as big as him is a challenge,” said Applejack, “but I want you to know that licking it and rubbing your face against it is fine. The point is to get him riled up, not to make him pitch his pudding in the wrong hole.”
Pinkie raised a hoof. “Wait. You can’t get pregnant from giving a blowjob?”
Applejack blinked. “Are you shitting me?”
“No, I mean, like, his stuff all goes to your tummy anyway, right?” Pinkie rubbed her belly, looking genuinely confused. Her sisters stared at her in bewildered shock.
Applejack frowned. “Pinkie Pie, what’s the capital of Yakyakistan?”
“Kabull!”
“And what’s the square root of 987?”
“That’s easy! It’s 31.416556144…”
“But you don’t know how sex works?”
“But I do!” Pinkie twirled her hooves around each other. “The boy puts his dinky winkie in the girl’s holsey wolsely, and he ejaculates, and the sperm travels through the cervix to the uterus, where conception occurs when…”
“Does your mouth connect to your uterus?”
Pinkie Pie opened her mouth. Then she closed it again. Light dawned behind her eyes. “Ooohhh! Wait, you’re right. So that’s what I’ve been doing wrong! Sorry, I got all turned around. Pony insides are confusing.”
Macintosh ignored all of this nonsense and nuzzled Apple Bloom’s tail aside. Her soft little ponut rested beneath it, puckered and rounded and clean and pure. He licked its outside. Apple Bloom trembled. He felt her ass muscles clenching and straining as she struggled to push her face further down his cock. Tried and succeeded! Her tight, silky mouth gave way to her even tighter, silkier throat. Macintosh shook with happiness at the feeling of his littlest sister’s body opening for him, bending her will to the almost impossible task of getting him inside her. He could get at her ponut better now; resting his jaw on her croup, he pushed his tongue against the pucker.
“Apple Bloom’s a champ, though,” said Applejack. “She looks like she’s gonna go for the whole thing. Don’t try too hard, little sister! You get that thing all the way in and it’ll be coming out your ass.”
Inexorably, Apple Bloom moved forward. Macintosh wished that he could see her impaling her face on his cock. Not that he wasn’t worried about his sister’s safety. But… Applejack would keep an eye on her, right? He put the thought aside and licked his way down Apple Bloom’s taint to her plump little pussy. Her ass cheeks were rock hard, almost pure apple-bucking muscle, but her coat was like velvet. He rubbed his cheeks against them while he licked, playing in her sweet mare goo with his tongue.
Applejack scrambled up on Macintosh’s back and hung over his side so she could point at whatever Apple Bloom was doing down there. Apple Bloom’s blowjob felt… so incredible. Her deep throat technique was flawless!
“Now you’ll see, Apple Bloom’s deep throat technique is flawless. Note how loose she keeps her jaw. She’s letting her throat do the work. But. I think she’s making a mistake. See…”
Macintosh wished Applejack would just shut up and let him enjoy this. Apple Bloom’s lips rested on his medial ring. Her throat flexed around him, milking him hard. The hot silkiness around his cock made him want to blow his load right into her tummy. He could get away with that, right? He wasn’t trying to get Apple Bloom pregnant. He started to rock his hips, making his little sister gurgle. His tongue found her hot nubbin, which made her shake. The shaking and the gurgling made him thrust and lick harder.
“Whoa, whoa, easy you two!” yelped Applejack. Macintosh’s thrusting motion rocked her back and forth on his back. Holding her hat in place with one hoof, mane flying, she swung down around his neck and grabbed Apple Bloom by the hips, tugging her off of his cock.
“Hey! That ain’t fair!” said Macintosh, grabbing for Applejack, but getting only her hat. “I was almost there!”
Apple Bloom’s lips popped off his flare. “It’s not fair! He was almost there!” She stomped her hips, body a-shiver with sexual frustration.
Applejack yanked her hat off of Macintosh’s hoof. “That’s not the point. We’re here to make foals, not have fun!”
MacIntosh thought she was being unreasonable, but Apple Bloom turned around and put her face on the floor and her ass in the air. Her pussy winked wide open for him. “Please, daddy?”
He charged her, slamming his flare against his little sister’s pussy. It bounced off, and both brother and sister roared with frustration. Applejack grabbed him by the shaft and helped guide him inside. Apple Bloom’s pussy enveloped him, hot and slick and so wet it squirted on the floor when his probing cock displaced the fluids. He drove himself in up to the medial rig in two thrusts, then kept pounding away, squashing Apple Bloom’s womb flat, gradually hammering it deeper into her body.
“Oh yeah, oh yeah,” said Applejack.”Fuck her hard! Show these mares how you’re gonna make a baby in ‘em.”
“Daddy, daddy, I wanna cum!” whimpered Apple Bloom, as his thrusting pushed her pretty face back and forth across the rough hardwood floor. “Make me cum!”
Applejack slid the soft frog of her hoof down the belly of Macintosh’s cock and pushed the tip of her hoof wall against Apple Bloom’s clit. The extra stimulation broke Apple Bloom. “Mommy! Daddy!” she squeaked. Her eyes rolled up into her skull. Her tongue lolled out, splashing drool. Her pussy clamped down on him so hard it almost pushed him out.
“Mother of… FUCK!” roared Macintosh, jamming his cock against his little sister’s womb hatch. His cum sprayed inside of her, quickly filling her pussy and her womb and then squirting out around the lips of her pussy because there was nowhere else for it to go. His legs trembled. His eyes rolled up into his head. He drooled right on Apple Bloom’s bow. He felt like everything from his belly button back had just… exploded, and transformed itself into cum.
It might have. He really couldn’t feel anything back there.
“Now that is what I’m talking about,” said Applejack, drawing her hooves away from Apple Bloom’s pussy dripping white. “White gold, ladies. Your ticket to foaltown. Why don’t you all come down here and have a sniff? Rub some in your pussies, if you want. It’s nice and fresh, and you never know which load that one lucky sperm is gonna come from.”
“Ah! Ah!” said Apple Bloom. “That felt so good!”
“Eyup,” rumbled Macintosh. His dick was too sensitive to move right now, and the prospect of trying to wriggle it out of Apple Bloom’s tiny pussy made him want to wait and enjoy the afterglow a little more. As much afterglow as they were allowed to have, anyway. Three of the four Pie sisters descended on them like cute harpies on a jizz buffet, sniffing and stroking and licking up his stallion sauce. Maud lay on her back under him, coverall up over her tummy, and Marble and Pinkie rub jizz into her pussy.
“There’s not enough,” said Maud. “Most of it is inside her. Pull her off of him.”
He yelped as everypony roughly pulled him and his littlest sister apart. His cum came pouring out of Apple Bloom’s pussy, flooding onto the floor before greedy Pie sister hooves poked in the stream to let it puddle up in their frogs. They passed it to one another, shoving it up between thighs, rubbing it into their cunts. Drips splattered all over their lower bodies.
Apple Bloom crawled out of the melee as soon as she could get away, and bounced over to where Macintosh sat, watching the show.
“It’s gonna be an interesting week, isn’t it, big brother?” she said, nestling against his side.
“Eyup.”

                     Day 2: Limestone                      
//-------------------------------------------------------//
Day 2: Limestone
Apple Bloom whisked back and forth between the table and the kitchen on her hind legs, carrying trays of apple fritters and stone scones. She wore a lacy little apron that Macintosh thought set her muscular ass and thighs very nicely. She and Pinkie Pie had taken over the cooking from whoever had cooked the tasteless quinoa abomination last night, and Macintosh tore into them with abandon. Even the stone scones weren’t that bad, once you got used to the crunch.  
Applejack’s forelegs slid up from behind, wrapping as far as they’d go around his cider gut. “Ease up, lardo. You gotta get to work soon.”
“Gotta load up on carbs,” said Macintosh, reaching for another scone. "Gonna need the energy."
Limestone’s chair scraped the floor as she got up from the table. “Damn right, bitch. You’re mine today. Stop stuffing your stupid fat face and follow me.”
Macintosh blinked, and gently put the rock scone back on his plate. All right then. As he left, Marble scurried to the bookshelves and pulled out the Ponedemic box. Darn it, he liked that game.
He was glad he was getting Limestone out of the way early. She was easy on the eyes, there was no question of that — she had pretty green eyes and a cute snout that her resting bitch face somehow only made cuter. She was a bit thinner than he usually went for, the slimmest of the Pie sisters, but she had a round butt and that was all that mattered to him body-wise.
No, the problem with Limestone was that beauty was only skin deep, but ugly went all the way down to the bone. What would she want to do to him? Would she want to hurt him? Humiliate him? She stepped through her bedroom door, kicking it on the way by to keep it open for him. He took a deep breath and followed her inside. He took great care in locking the door, then turned to face Limestone, ready for anything.
She sat still, staring up at him, body trembling. Her face had softened, it’s usually steely glare replaced with wide eyes and trembling lips. “I’ve never done this before. Is it going to hurt?”
Macintosh’s jaw fell wide open. “You’re… you’re a virgin?” Limestone hadn’t participated in the cum play last night, had she? Macintosh had assumed she was just too cool.
Limestone nodded. “Who’d want to have sex with me? I know how awful I am.”
“That’s… that’s not…” Macintosh stumbled, trying to think of the right thing to say. He was really bad at thinking of the right thing to say.
Limestone hunched down into a little ponyball, “See? You’re only going to have sex with me because you have to.”
“I don’t have to,” rumbled Macintosh. “And you don’t have to if you don’t want to.”
Limestone scowled. “I want to. I at least want to know what it’s like. Just…” she looked down between his hind legs anxiously. “Be gentle?”
“How about we start with kissing and cuddling, and go from there?”
“But the foal?” She traced a hoof over her belly. “I want a foal.”
Macintosh climbed up onto Limstone’s little twin bed, the timbers creaking underneath him. “You gotta focus on what you’re doing right now. Don’t worry about the future. It’ll take care of itself.”
She climbed up after him, sat with her legs folded under her and looked up at him with deer in headlights eyes. She had no idea what to do, did she? He leaned down and rubbed his lips lightly against hers. She didn’t move. Macintosh gave her a chaste peck on the cheek and pulled his head back. “Okay, so, you gotta do stuff?”
Limestone flipped her tail up over her back and looked up at him hopefully.
He rolled over onto his side and showed him that his cock was still nestled soundly in its sheath.
“Well, I can hardly be blamed if you can’t get it up for me,” growled Limestone. She must be a little more comfortable if she was reverting to her normal personality.
“Stallions ain’t just fuck machines. We got feelings, too.”
Limestone tapped roughly on his chest fluff. “Yeah. Your sister said you were ‘sensitive’. What are you, some kind of faggot?”
“Bi.”
Limestone blinked. “Oh. Sorry.”
Macintosh tilted his head towards the back of his body.
Limestone’s eyes widened. “You’re hard!” She whipped her head back towards him. “You got hard because I called you a faggot?”
“If a stallion said it, I’d buck ‘em in the face. But if a mare says it while she’s in bed with me… well, it’s kinda cute. Shows she’s got spirit.”
Limestone sneered. “Oh I have spirit, do I?”
“Mare, you got more spirit than a ghost convention.”
Limestone tilted her head to one side, her sneer softening into a wicked grin. “Spirit,” she said and pressed her lips against Macintosh’s.
He licked her lips lightly, and she opened her mouth for him. He caressed her tongue with his and pulled her small slim body close to his massive one. She wrapped her forelegs around his neck. He felt her chest moving against his, breath quick and light. He held her with his forelegs. They kissed long and slow. Macintosh was acutely aware of the way Limestone’s lean but soft belly rested against the belly of his cock, but he willed himself not to thrust his hips. He didn’t want to intimidate her. He was, after all, a lot to take in.
Limestone’s slid her hooves over his forelegs, shoulders, and chest. Gradually, hesitantly, she moved her hooves lower. Macintosh found himself tensing as she neared his cock. Was she going to touch it? He’d warmed to this fiery mare quite a bit in the last few minutes; he’d be disappointed if she backed out. Deep breaths. There were plenty of willing mares in this house, and if she didn’t want to… oh Harmony, she touched his dick. He trembled and kicked, trying to dry hump her.  
“Does that feel good?” whispered Limestone nervously.
“Eyup.” Her tentative, gentle touch glided delicately over his cock, sending tingles down his shaft to the special spot behind his balls.
“It must. You’re drooling.”
“Don’t stop.”
Her soft hooves explored his thick, veiny shaft. She caressed the flare, and her hoof came away sticky. “Okay, you’re drooling from both ends now.”
“Pre-cum,” said Mac. “It just makes little spurts.”
Limestone frowned slightly, as though she didn’t approve, but kept stroking him. Her strong thin thighs wrapped around the sides of his shaft, pulling it against her tummy. Macintosh bucked, cock grinding against her belly and thighs and chest fluff and bopping her in the jaw. Limestone groaned, and reciprocated by rubbing her pussy against his balls; it smeared thick sticky mare goo across them.
He rolled her onto her back and bucked hard, pressing her into her rough wool sheets. He began to feel the burn of climax fill his balls. Too soon. Gasping, he pulled himself off his cousin. A string of pre linked her chest ruff and his cock tip.  
“Where are you going? What are you doing?” said Limestone, forehooves grabbing for him.
Macintosh leaned down to kiss her throat. “What do you think I’m doin’?” He rubbed her nose in her chest fluff, licking it clean of his pre, then kissed his way down her belly. Her snatch smelled dry and clean, like a sexy rock.
“Oh. Oh gosh. You’d do that for me?”
Macintosh chuckled and replied by dragging his tongue around her glossy gray pussy lips, slicking them with spit. Limestone squeaked and bucked her ass in the air, bopping him in the nose with her pubic fluff. “Ah! Don’t stop!”  
Macintosh wasn’t about to. This was a perfect time to do some reconnaissance. Her pussy was absurdly tight, but her hymen had already been broken. Not surprising, living on a rough and tumble rock farm. He wiggled his tongue inside, spreading her open gently, tasting her, feeling the way her pussy muscles squeezed his tongue.
“Oh, Harmony! There! Right there! Lick there!” she squealed. Macintosh grinned. He knew how to treat a lady. He licked what he presumed to be her g-spot vigorously.
“No! Further in! And to the left!”
Macintosh followed her instructions, and she punched him in the head. “No, you idiot! My left!”
He dragged his tongue over and was rewarded by a shriek of pleasure from his cousin. Her thighs and forehooves gripped his head. He licked hard. She jammed her sopping wet pussy against his snout. Damn, eating pussy was fun. He stroked her thighs, feeling her wiry muscles tremble. Almost there.
She came violently, pussy clamping down brutally hard on his tongue, legs squeezing so hard his skull creaked. He held his tongue in place, drawing out her orgasm until she stopped thrashing. But he wasn’t done.
His tongue felt bruised as he pulled it out of her cunt, but he ignored the pain and slid it up her slit to her twitching clit. Limestone made an incoherent noise as he circled it gently, and pushed her hooves against the back of his head.
“You like that?” rumbled Macintosh smugly.
“Abb aha! Ab ha!” growled Limestone, pushing his mouth back down towards her clit.
Macintosh licked in slow, lazy circles. Limestone whimpered and writhed; her hips gyrated in a way that told him he wasn’t going fast enough for her. Too bad. He was gonna take his time with this one — with a lot of mares, more orgasms just made them hornier, and a hornier mare meant more fun for him when his turn came. His tongue glided over her tender flesh. Her little double nub pulsed with her heartbeat, hot, hungry, needy. Macintosh looked up between her thighs. She was trembling and she had both hooves over her eyes. A stream of drool rolled down her cheek. He gave her clit a hard push with his tongue, and she bucked so hard she whacked him in the nose with her pubic bone.
Blinking away the pain, he put his hooves on her flat little teats to hold her still and did that again. Pushed it up, let go, pushed it up against. Licking her like a very tiny popsicle, he pushed her deeper and deeper into pleasure. Her thighs vibrated against his ears. She let out a shriek so high pitched Macintosh could barely hear it, and hot mare goo squirted across his jaw and splashes against his neck.
“En… eh… enough!” wailed Limestone, kicking his head away frantically.
Macintosh wiped his throat and licked Limestone’s goo off his hoof. “Was it good for you?”
“Asshole. Please fuck me now.”
A tingle shot down Macintosh’s spine, and his cock pulsed, squirting pre across the bedsheets. He lined his shaft up with Limestone’s pussy. It looked like an elephant’s trunk lying next to an ant hole. “I think we’re gonna need some lube,” he said.
Limestone struggled to push her torso up and shoved her bangs out of her eyes. “Why? It's it too big? Can we not do it?”  
“Where there’s a will, there’s a way, but we gotta prepare.” Macintosh sat up in bed. “Apple Bloom!”
His sister stuck her head in the door. “What’s up, daddy?”
“Please tell me Applejack was lying when she said we didn’t have any lube.”
Apple Bloom grinned. “We got enough lube to birth a whole herd of hogs! How much you need?”
“A jar. A big one.”
A few minutes later Apple bloom waddled in on her hind legs, carrying a jar of clear goop bigger than her chest. “Think that'll be enough?”
Macintosh stuck a hoof in, and it came out glistening. “Twilight’s special?”
“Yup!”
“That'll do.”
They shared a kiss, and Macintosh stroked Apple Bloom’s ass cheek on her way out, feeling the way the tight-tied cord of her apron dug into her butt. Then he soaked his cock in lube, covering every inch of it with a thick layer.
“Do you need help?” said Limestone, still on her back.
“Nope.” He scooped up a hoof full of goop and rubbed it gently into Limestone’s pussy. “You ready? It'll be easier if you rolled over. Abyssinian style is hard to do.”
Limestone grinned. “Nope. I’m not going to turn my back on you for a second. Anyway. I wanna watch.”
Macintosh chuckled. “All right.” He lifted her hind legs, hooves poking up into the air and spread as wide as they’d go. Then he slid his cock up against the mouth of her tiny cunt and started pushing gently. The crown pushed uselessly against her little lips for the first half dozen thrusts, then the lube began to do its work, and he felt her gradually sliding open.
“Oh. Oh Harmony,” gasped Limestone, her voice trembling with anxiety. She held her forehooves curled protectively against her chest.
“You’re tense. Do you need me to stop?” rumbled Macintosh.
“No. I’m tough. I can take it. Just be gentle. Please.”
“How about I rub against your outside for a while?”
Limestone nodded. She closed her eyes and breathed slowly and regularly, her narrow rib cage rising and falling gently. Macintosh knelt over her on his hocks and rubbed his cock back and forth against her pussy. It felt nice — not something he could get off on unless she pushed her thighs together, but nice. Too bad her teats weren’t bigger, or he could fuck ‘em. Pregnant mares had big teats. He wondered if he’d get a chance to play with any of them after he knocked ‘em up. Applejack, at least. That was a nice thought.
As he thrust, he felt Limestone’s posture soften, her muscles loosen. Her cunt felt a little more open — or was it his imagination? He didn’t ask; he didn’t want to rush her. But Limestone reached out a hoof and pushed the crown of his cock back towards her pussy. “In.”
“Eyup.” He moved as slowly and carefully as he could. Her lips, massaged into submission, spread around his cock. He gasped — her flesh closed in like quicksand, gripping him hot and pulling him deep. She felt amazing inside; a supple softness in sharp contrast to her rough personality. He wanted to slam his way into her, to feel that softness all the way to his balls, but he gritted his teeth and held back. He needed to make sure she enjoyed herself — not only because he was a gentlepony, but because he wanted her to offer her sublime cunt up to him again.
“It’s so big!” groaned Limestone.
Macintosh grinned. He knew damn well how big his cock was, but all the mares had to tell him about it anyway, and he sure didn’t get tired of hearing it. “You like it big? It doesn’t hurt, does it?”
“Shut up and fuck me harder.”
He pushed forward inch by inch, long cock sliding gradually into the thin, glossy O of Limestone’s stretched, virgin pussy lips. His forehooves gripped her thighs, holding her steady, enjoying the way her lean muscles flexed as she twisted underneath him. “How do you like getting fucked?”
“ You’re touching my clit… touching everything inside me. I want more.” She looked up at him, eyes glistening with a vulnerability he’d never seen in her before. He thrust, pushing into her almost to the medial ring, and he hit something that wouldn’t give any more. Limestone gave a startled gasp and arched her back. “What are you doing to me!”
“Hit your womb, honey,” said Macintosh. “Does it hurt?”
“Feels a little funny. I’m okay.” She slid her hand down her belly. “Can I feel?”
Macintosh nodded. She poked at the slight bulge his massive cock made in her thin belly; he felt her probing hoof through the wall of her abdomen. “You’re filling my whole tummy,” she purred excitedly.
Macintosh nodded. “I wanna fuck you. I don’t think it’s safe to go any deeper in you. But you feel so good.”
Limestone rubbed her hooftip at her clit. “Make me cum?”
Macintosh smirked. “I’ll do my best. Hard without the ring.”
Limestone grabbed the back of her knees, pulling her hooves back to the sides of her head. Her pussy opened out around Macintosh, and he found himself sliding deeper in. “V-virgin?”
She laughed. “I’ve always been flexible. Come on. I’m a tough girl. Have your fun. But if you come before I do, you’re in shit city, got it?”
Macintosh nodded frantically. A little bit of extra room wasn’t a bad thing; it created some suction, and let him get in up to the ring. He slid in and out in short jabs, rocking Limestone’s body back and forth on the bed, his medial ring plucking at her clit. She gasped and rolled her head back on the bed. “Harder!” she groaned.
Macintosh wanted to object, to hold back, but his hips had a mind of their own. The jabbed forward, slamming his flare into her foal hatch, pushing her slowly across the bed. His balls boiled; he wanted to cum, but he had to hold back. The bed groaned under them, wood frame shaking under an assault it had never endured before. Her pussy slurped at his cock, squelching hungrily, flexing around him. Limestone called out with rising desire.
His thrusts pushed her head over the edge of the bed. She looked up at him with fire in her eyes. “Don’t you dare fucking cum. Don’t you.. don’t you… Oh, Harmony!”
Her pussy slammed down on him, clenching so hard he felt like she would wring him out like a tube of toothpaste. Her body twitched, all four legs stuck out straight, and she screamed. Macintosh bit down on his tongue, trying not to cum, trying not to get squeezed out by Limestone’s clenching pussy muscles.
“F-fuck,” she groaned, tears streaming down her cheeks. “I’m not crying.”
“You ain’t,” lied Macintosh.
“Cum in me, you limp-dicked little faggot.”
Orgasm rolled over Macintosh like an avalanche flattening a hapless skier. Blinding bliss blasted through his body in a wave. His balls pulsed. He felt the first gob of cum rushing through his shaft to blast against Limestone’s womb hatch. The seal of her pussy around his cock kept the cum from leaking out, and there was no space in her cunt. The only place for his load to go was her womb. Her tummy grew with every squirt until it rose in a smooth dome over her skinny body.  
“What the hell. Is this normal?” said Limestone, looking at her distended belly in awe.
“Holy Harmony.” Macintosh slid one hoof over the curve of her belly and then wiggled it from side to side. He could hear her uterus slosh when he wiggled her tummy. “Are you pregnant already?”
“I hope the foal gets my brains,” growled Limestone.

                       Day 3: Marble                       
//-------------------------------------------------------//
Day 3: Marble
The next morning Limestone’s belly was still swollen. Macintosh felt her watching him jealously across the breakfast table, looking away only to glare at Marble, whose turn was today. Marble smiled smugly back at her, which made Limestone tremble with rage.
Macintosh and Limestone had sex three more times yesterday, and each time she’d enjoyed it more, while he’d enjoyed it less. The third time he took almost an hour to cum, and in the end they’d had to resort to calling Apple Bloom in to rub her ass in his face so he could force out one final load.
Now, somewhat restored by a good night’s sleep (in a bed by himself, thank Harmony) he wondered what to expect from Marble. He tucked into his eggs and gravel muffins, thinking he should ask Apple Bloom what Marble was into; but when she was done serving breakfast she and Marble went off to Marble’s bedroom before he could ask.
Without Marble to explain board game rules, Macintosh, Applejack, Maud, Limestone and Pinkie were at a loss to entertain themselves. Pinkie suggested they play War, which Macintosh was fine with initially. He’d like the game as a colt. But after a few rounds of play, he realized that the game was completely random, and the only thing he was doing was turning over cards.
Without Marble to restrain her, Pinkie began making up rules. An hour later, they were building card forts and rolling marbles at them, which the mares all enjoyed. But Macintosh’s hooves were too big and clumsy to stack cards, and if he tried to use his mouth the cards got wet.
“All set, daddy!” called Apple Bloom from Marble’s bedroom.
Whatever was in there, it was better than this nonsense. Was Marble a virgin, too? She was awfully shy. He hoped not, though. Virgins were challenging. Ideally, she’d be nice and experienced with simple, normal tastes…
Macintosh opened marble’s door to find her trussed up like a hog at a rodeo and hanging from the ceiling. “Oh holy mother of Harmony.”
“Do you like it?” said Apple Bloom, beaming.
Macintosh tilted his head to one side. “I can’t rightly say.”
Marble's eyes began to tremble and moisten.
Macintosh waved his forehooves frantically. “No, no, you’re beautiful! I just… I’ve never done bondage before.”
“Don’t worry! I did all the hard stuff!” said Apple Bloom, chest thrust out proudly. “I put her at the right height and everything!”
Macintosh walked around Marble slowly, contemplating. His cock slid out of his sheath and stiffened until he was so hard his flare kept getting tangled in his forelegs.
His eyes were drawn to the way the ropes and the corset-like saddle she wore hugged her strong but curvy body. Ropes dug in around her tummy and teats and pulled her thick ass cheeks apart to show the bases of the butt plug and dildo stuffed into her rear holes. Ropes around her thick thighs spread her hind legs, tying them to the same ring on the ceiling that held her main body. Her forelegs were tied together and down to keep them helpless and out of the way; her hooves dangled half an inch above the ground. An odd bridle, complete with dangling reigns, covered her snout; the bit spread her jaw open and held what looked like the base of another dildo inserted into her mouth.
Her neck was held still by a strap tied between the back of her head and the base oh her tail. Unable to move in any way, her eyes rolled to track Macintosh as he walked around her. The effect, for him, was at the exact mid-point between insanely arousing and extremely disturbing.
“What do I do?” he asked.
Apple Bloom grinned. “Anything you want. She’s helpless. She’ll tap on the floor three times with her forehooves if we hit a boundary. But she and I had a long talk about it and she doesn’t have any. Leastways, not any you’re likely to cross.”
Macintosh raised an eyebrow. “So why does a mare who’s experienced at expert level BDSM need my help getting pregnant?”
“She doesn’t. She just thinks it’s hot to get knocked up by her cousin.”
Marble let out a muffled, gurgling “Mmmmhmmm.”
Macintosh cringed. He cared about his hypothetical future foals and wasn’t sure about putting one in a mare who just wanted to be bred for sexual reasons. But he’d take care of it if he had to.
“You seem hesitant,” said Apple Bloom. “Want me to demonstrate?”
“Eyup.”
Apple Bloom stood on her hind legs on Marble’s bed, which had been pushed to the edge of the room. She wore black stockings, a black bow, black lipstick, and a sort of harness of straps that served no purpose except to draw attention to her pussy lips and teats. It was cute, he guessed, but he hoped they didn’t expect him to put on an outfit. She hooked a hoof in Marble’s reigns and swung her over. She eased the dildo out of her mouth, and pulled… and kept pulling. The thin, floppy silicone dildo was over three hooves long. Apple Bloom held it sideways in her mouth like a pirate on a romance novel cover, and mashed Marble’s snout against her crotch. Marble was able to get her tongue out through the bit and slathered it lasciviously over Apple Bloom’s dripping cunt.
Apple Bloom picked up a riding crop from the bed and tapped Marble on the cheek with it. “Bad slut. No stampeding for the clitoris. Lick my teats first.”
Macintosh watched with a mix of protective jealousy and perverted lust as Marble ran her tongue back and forth over his little sister’s nipples.
“Don’t just stand there with your mouth hanging open, daddy. She’s got a whole other end.”
Macintosh sniffed tentatively at Marble’s dangling rear. She smelled like lube, rope, rubber, lust, estrus, and a dry rock smell similar to Limestone’s. The way they ropes squeezed her ass cheeks into tight hemispheres was unnatural and disturbing, but it also made his cock pulse. He wanted to bite them, so he did. Teeth sinking slowly into firm flesh. Tongue against silky coat. Marble moaned hungrily into Apple Bloom’s cooch.
“Oh, she likes that, daddy. Do it more,” purred Apple Bloom, tousling Marble’s mane like she was a dog.
“Mmmhmmm.”
She looked down at Marble and tapped her on the cheek with the riding crop again. “Don’t stop licking, whore.”
Macintosh groaned and moved to gnaw on Marble’s other cheek, covering its smooth roundness with glowing pink teeth marks. Marble had such a perfect ass — not that there was a shortage of perfect asses in this house, but it was so much thicker than her older sister’s. He traced the edges of her crack with his tongue, eying the base of her butt plug. It was very thick, distending her glossy ponut into a thin gray ring. He wasn’t supposed to fuck that — he was supposed to be making foals, here, not plowing posteriors for his own personal pleasure. But it wouldn’t hurt to have a look in there, would it?
He waited until Marble hit a good spot on Apple Bloom, making his little sister’s eyes roll back into her head in pleasure, and gently wriggled the plug out of Marble’s ass. It came free with a soft pop, dripping lube. He gasped — his cousin’s ass was beautiful. Gently fluted pink flesh leads back into mysterious darkness. Lube thick enough that you could probably drive a train in there glistened on the room’s soft light. He glanced up at Apple Bloom again. Still distracted. He made eye contact with Marble. She was quite aware of what he was doing and gave him the slightest little nod.
Macintosh grinned and mounted his cousin. His flare poked against her well-prepared ponut. He felt her squeeze it open for him, and he slid right inside. Bliss. Marble’s soft, tight intestines massaged him, caressed him, welcomed him in. He sank deep into her — where his sister’s virgin pussy had been an unmarked trail, her ass was a well-traveled four-lane highway. He rode that highway nice and slow, observing marked speed limits, all the way up to his balls — the big advantage of anal was that he didn’t have a depth limit unless his partner was shy about having their internal organs rearranged. Then he picked up speed fast. He wrapped his forelegs around Marble’s pouty, rope-corseted tummy and rammed his belly and balls against her plump, muscular ass.
Marble groaned and squirmed back against him, eyes rolling back into her head in pleasure. Macintosh gave her a nice, sturdy shove, jamming his massive cock as deep into her guts as it would go. Drool trickled out of the corners of her mouth. Macintosh grinned — this bondage thing wasn’t so bad.
“You enjoying that pussy, daddy?” purred Apple Bloom, looking up into his eyes. Their heads were almost level in this position; leaning across Marble’s suspended body brought her delicious lips barely an inch from his.
“Eyup,” said Macintosh, lying by omission.
“You gonna make a foal in your cousin?”
“Eyup,” he said, lying explicitly.
Apple Bloom narrowed her eyes lasciviously. “You gonna kiss your little sister?”
Macintosh slid his tongue into his sister’s mouth with all the not-very gentle passion he was hammering his cousin's ass with. He jammed his tongue into her mouth like a cock, filling her to the top of her throat. He felt her groan into his tongue, felt her beginning to tremble as Marble’s tongue brought her closer and closer to ecstasy. His cousin’s bowels flexed around him. Her bound thighs clenched against his hips. Her ass and tail rubbed against his belly. He could spray inside Marble’s ass at any second, but he though she might be the type who could cum from anal, and he wanted to give her plenty of time for that. He could feel the dildo moving through the thin wall of flesh between her asshole and her pussy; he didn’t know what it felt like to have a pussy, but he imagined being stuffed in both holes must feel amazing. Getting it up the ass sure didn’t suck; he knew that much.
Macintosh thrust his cock deep into Marble, squishing her snout against Apple Bloom’s crotch, grinding his balls against the dildo base sticking out of her pussy. Fuck, fuck, fuck, her guts felt so good. He had to stop kissing Apple Bloom and grit his teeth to keep from cumming.
He clenched down the muscles deep behind his balls to keep from cumming and lost himself in his sister’s gentle kiss. Her tongue moved against his as she moaned, her cries becoming deeper and hotter as Marble’s expert tongue pushed her up to the edge of orgasm and kept her there.
“Fucking let me cum, cunt slave,” Apple Bloom growled, grabbing Marble by the ears and yanking her forward. Marble squeaked. Apple Bloom yowled. Macintosh watched a ripple of pleasure move through his sister’s body, furs standing on end as pleasure melted her brain. “Ah! Ah! Ah!” squealed Apple Bloom. Her eyes rolled up into her skull. Her tongue lolled out of her mouth. Drool dripped from her chin.
Macintosh felt Marble convulse around him. Her thighs shuddered against his hips. Her ass muscle clenched down around his cock shaft so hard it forced the blood painfully up into the crown.
That was too much for him. His orgasm started deep behind his balls and spread out, burning up his spine as cum shot through his cock. He felt his balls pulsing; somehow even after all the work he’d done the past two days he could still put out a massive load.
Pride filled his heart as he slid his dick out of Marble’s ass and huge amounts of cum flowed out around it. He was amazingly fertile, and…
“Macintosh!” said Apple Bloom. “You wasted it!”
Macintosh’s pride turned to shame. His shoulders slumped. “Eyup.”
Appl Bloom glared at him. “You wasted your cousin’s time. And mine. You proud of that?”
“Nope.”
Marble giggled.
“Oh, were you in on this too?”
“Mmmhmmm.”
Apple Bloom bapped Marble in the nose with her riding crop, and lay down on her belly on the bed with her forehooves hanging over the edge. “Bring that big limp hose over here, daddy. I’m gonna suck it hard again.”
Macintosh’s eyes widened. “It’s been up her ass.”
Apple Bloom smirked. “And I bet giving your innocent little sister an ass-to-mouth is gonna make you nice and hard again, isn’t it?”
Macintosh nodded so hard his brains rattled. He stood over Apple Bloom, forehooves on her muscular ass cheeks, and she took his cock in her hooves, rubbing the slimy, limp shaft against her soft face. He moaned as he felt her tongue lapping his cum off the shaft. Blood pulsed through it and he began to stiffen. Apple Bloom wrapper her lips around his flare and sucked, draining any remaining cum out of him. He gasped, feeling her jaws widen as he hardened. He pumped his hips, pressing his flare to the top of Apple Bloom’s throat, but she wiggled away. His crown popped wetly from her lips.
“You ready to fuck again?”
“Eyup.”
Apple Bloom tapped his cheek with the riding crop. It stung more than he’d expected. “That’s a good soldier. Get it right this time, okay?”
She helped him get the butt plug back in Marble’s cum-dripping ass and eased the colossal dildo filling Marble’s pussy loose. Mare goo flooded out around it and drizzled onto the floor. Marble was very, very horny. Her cunt gaped wide at first, just as pink and enticing as her ass had been, but quickly closed to a tiny slot little wider than Limestone’s. Macintosh leaned forward to sniff at it nervously.
“It ain’t gonna bite you, daddy,” said Apple Bloom. “And I don’t think she needs foreplay. Stop staring like a fool and get your big fat foalmaker in there.”
Macintosh reared up over Marble and bashed his cock against her opening. Apple Bloom held Marbel’s hips steady and helped guide him inside of her. His cock sang with pleasure — Marble’s little cave was almost as tight as Limestone’s but more used to heavy traffic. She moaned and arched as he hammered away, driving himself in up to the medial ring before hitting resistance. Marble jerked and threw her head back as he bumped her womb hatch. Macintosh paused, suddenly worried if he was being too rough.
“You okay?” he said.
Marble thrashed and tried to talk, her voice unintelligible though the bit in her mouth.
“I think she wants it harder. You want it harder, Marble?” said Apple Bloom.
Marble nodded as hard as her bindings allowed her to.
Apple Bloom grinned. “I think you’ve got a green light to go to town on that pussy, daddy.”
A shiver passed up Macintosh’s spine. He shook his mane out to clear his head, hugged Marble’s middle tight, drew his hips back, and slammed his flare into her womb hatch. Marble squealed and bucked, helpless underneath him. He jammed himself forward again, her cunt gripping him hard. He wanted the go deeper, but the harder he thrust, the more the stupid bondage tackle let her swing away from him. Frustrating.
There was nothing for it but to grab a mouthful of her mane. Thus secured, he thrust forward into her, pounding, pushing, enjoying the feeling of her tight, sloppy wet pussy gripping his cock. He pulled back to the medial ring on every thrust, making sure it plucked against her clit.
This technique paid off quickly. Her pussy began to spasm around him, then clenched down hard. He groaned at the sudden pressure, and bucked forward into her, resiting being pushed out. Whatever nerves this motion hit worked well for her — her tunnel quivered, then clamped down again, her whole body shaking as a second, more powerful orgasm took her. He let go of her mane and tugged her back so he could get a look at her face. Her eyes were glassy, her tongue hung out of her O bit, her breath was fast and hot. He pushed her forward until his medial ring was pressed against her nub, and jerked her back and forth on the rope tying her to the ceiling.
“Mmmmmgggnnnh!” said Marble, eyes rolling up into her head. She slouched in her bonds, panting, sweaty, expression dazed.
“You fucked her stupid, daddy,” said Apple Bloom, bouncing up and down on her four hooves excitedly. “Now cum in her!”
Macintosh groaned. As much as he was enjoying this, his balls felt dry. He worried he wouldn’t be able to finish. “Do me a favor, Apple Bloom?”
“Anything for you, daddy.”
“Can you eat my ass while I fuck her?”
“Can I!” His little sister was out of his sight so fast she blew up a dust cloud. He felt her cute snout wriggle between his ass cheeks and her tongue slide against his ponut. He rocked back and forth between the two mares, two-thirds of his cock buried in Marble while his little sister’s tongue wormed its way up his ass. His worries floated free from his mind. His balls tightened. His sister’s long tongue found the special spot inside of him, and a wildfire broke loose. Massive gouts of cum gushed through his cock, pumping hard and fast into Marble’s battered womb. Trapped inside her by the tight fit of his cock, it swelled rapidly until her belly strained at the ropes binding it.
“Ah! Harmony!” moaned Macintosh as pleasure roared through him. When it left, his balls ached and his limbs felt weak. He slid out of his cousin. His limp, over-sensitive cock slipped free, followed by a white river.
Marble tapped her forehoof lightly on the floor three times. She was ready to be let go. Apple Bloom worked quickly, handing Macintosh rope after rope to hold as she unbound her cousin.
“Doing okay?” said Apple Bloom, helping her down on to the floor.
“Mmmmhmmm,” said Marble, looking tired but satisfied. She shook pins and needles out of her legs and climbed onto the bed. Apple Bloom and Macintosh followed her, stroking her and praising her.
“You did so good in there,” said Apple Bloom, massaging her forelegs. “A real trooper.”
“That was incredible,” said Macintosh. He ran his hooves over her body, examining where the rope had left furrows in her tender flesh. He followed one around her hip and down her pelvis, then caressed the lower cusp of her swollen belly. “I love the little cum tummy your family gets.”
“Good to cuddle with,” said Apple Bloom, curling against her front.
“Eyup,” said Macintosh, wrapping his forelegs around both of them and pulling Marble’s back against his front.
“Mmmmhmmm,” said Marble.
They lay like that until they all drifted into an afternoon nap.
