Chapter 1
Click.
The sound of the bedroom door closing prompted Big Macintosh's eyes to open. He was laying with his back to the room's entrance. When his eyelids lifted, his vision flooded with moonlight leaking through the window. It sparkled against the wooden floor of the bedroom, illuminating corners of furniture and objects strewn about seemingly at random.
Big Mac breathed out slowly. He heard the rustling of movement as something made its way across the room behind him.
"What–"
"Shhh."
Big Mac’s body shifted as the weight of another body settled in beside him. He moved to turn himself fully around but paused at the sensation of a hand on his shoulder. The weight beside him shifted, lowering the center of the mattress as it sidled up next to him.
"Just calm down. Applebloom's still sleeping."
Applejack's voice crept into his ears as a gentle whisper, tickling his earlobes as it drawled over her tongue.
Big Mac sighed.
"I reckoned Applebloom would be in bed – but the question is, why aren't you?"
Applejack's hand moved from Big Mac’s shoulder down to his side, tracing gentle trails over his skin with the softest touch of trimmed fingernails. Applejack pressed her palms into Big Mac's muscular abs before sliding her hands around the front of him, locking both arms around his stomach.
"I can't sleep... my head doesn't wanna turn off." Applejack pulled her brother closer as she spoke, pressing her body against his back.
Mac kept silent, but his expression changed to a momentary curiosity as he felt his sister behind him. He pinpointed the sensation after a second's contemplation.
Applejack continued to rub her palms on her brother’s stomach as she lovingly pressed herself up against him. Her breasts were bare, and the feeling of her soft flesh on her brother's hard muscular back made her sigh. The contented exhale whispered into her brother's ear, blowing a tuft of his sandy blonde hair out of the way as she eliminated any distance between them. Her feet locked with Mac's, and she snaked herself against him like a perfectly interlocking piece.
Big Mac hissed a sharp intake of breath as Applejack's feet touched his own.
"AJ, you're freezing..."
Applejack separated the grip of her hands and traced one of them upward, languidly trailing her index finger over Big Mac's firm chest. She weaved the tip of her touch in between his pecs before branching to the left, circling his nipple repeatedly.
"Ain't no problem if you're here to warm me up."
As she spoke, Applejack pushed herself even further forward, pressing her chest into her brother's skin and savoring the warmth of his body against her sensitive supple breasts. Her hips moved too, grinding up against Big Mac's ass like an anxious boyfriend pleading for affection.
Big Mac sighed again. His sister's fingernail raked softly over his nipple, but he made no move to indicate its presence.
"Applebloom's over in the next room sleeping, AJ... and what time is it anyway?"
Applejack ignored the tone of her brother's questioning, instead concerning herself more intently with his ample musculature. She pulled her hand away from Big Mac’s chest and began to caress his shoulder, massaging the muscle with a touch between insistent and sensuous.
"Oh, it's about four PM, dinner should be ready soon..." she said with the hint of a giggle. Her hips ground forward again, lining herself up for a perfect thrust if she hadn't lacked the equipment.
"Very funny, sis." Mac tensed his muscles as he prepared to turn himself over.
"Wait!"
Big Macintosh flinched at the volume of his sister's outburst. He swiveled his head mid-turn. When AJ caught sight of her brother's expression, she grinned and then bit her lip with a guilty expression.
"Just... just lemme play for a bit. I promise I'll leave you alone after a little while."
"And exactly how long is a little while?" Big Mac didn't change his inflection at all as his sister's right arm shifted underneath him, bringing her hand further down and hooking her thumb in the waistband of her brother's boxers.
"Just until I can get you out of my head..." AJ murmured, snaking her hand inside her brother's underwear.
Big Mac was staunch, but he couldn't hold back a sharp intake of breath as his sister's fingers wrapped around his cock. His member was still mostly soft despite his sister's nakedness and repeated caresses – but even flaccid, his size was still more than enough to take up Applejack's whole hand.
Applejack moaned softly into her brother's ear from behind his back. She'd always loved how big he was.
While her right hand stroked slowly up and down, Applejack busied her left with her brother's muscular chest again. She pressed three fingers down with each movement of her arm, arching her palm and digging her fingertips into his skin. The rest of her body moved with her arms, grinding herself up against the solid frame in front of her. She lowered her mouth and kissed the back of Big Mac's neck, making a soft little smooching sound with each peck. Occasionally, her teeth bared slightly, biting down just a bit as her hands kept up their movement.
Big Mac hardened under Applejack's touch, regardless of the part of him content to admonish her for doing something she was well aware would lead to things more than loud enough to wake up their sleeping sister. Part of him wanted to stay firm and responsible and tell his sister that her creeping into his room in the middle of the night to sate whatever urges she had built up that day was completely unacceptable – but the other part of him was almost as firm, and rapidly reminding him that as much as he might resent Applejack's attention in the haze of his unprovoked interruption of sleep, she was masterful with her hands; the kisses on the back of his neck alongside the tits pressed into his skin weren't helping any either.
The full length of Big Mac's cock was pressed into his boxers now, as well as into the softness of his sister's palm, which she was stroking up and down almost painfully slowly, keeping a feather light grip on the giant mass of sensitive flesh between her fingers. As she bit down on the back of Mac's neck again, Applejack lowered her hand all the way down Mac’s shaft and spread her fingers out, tracing them down past the base of his cock and cupping his sizable balls in her hand. Big Mac let out his first groan, and Applejack met it with a hushed whimper.
"AJ..." Big Mac started, well aware that his noise-making was a slippery slope to something neither of them could keep quiet.
"Shush," Applejack countered. She pulled her right hand away from her brother's balls and her left away from his nipple which she had been pinching idly as she nibbled on his skin. The bed sheets rustled as she withdrew her right arm from below her brother's frame, raising it up before letting it rest just beside Big Mac's face.
He was still staring toward the moonlight – but now, his eyes were closed, and his idle expression had contorted into a self-combative half-grimace.
Without ceremony, Applejack raised her arm again and placed both of her hands astride her brother's boxers, then yanked them down to his knees. Big Mac raised his legs in an almost exasperated fashion, letting Applejack slide his soft cloth undergarments over his feet before tossing them onto the floor. The cool night air mixed with the heat from Applejack's body made Big Mac shiver slightly – he replaced the soft extra breathing with another sharp gasp as both of AJ's hands returned to his hardness.
"Roll over," Applejack whispered.
Big Mac complied wordlessly, rolling onto his back and presenting a full view of his engorged penis.
Applejack held her brother's cock like someone in awe of a natural wonder. She placed one hand atop the other, marveling in disbelief as both her palms barely contained the full size of her brother's shaft. His girth was impressive as well, but luckily not so engorged that she couldn't wrap her fingers around his member. Just barely, though.
She didn't waste any time. Applejack moved her hands up and down in tandem, abandoning the wispy caress of her previous preparations in favor of a proper, eager hand-job. She traced her lips with her tongue absentmindedly as she stroked, barely keeping a strand of saliva from falling from her open mouth. Big Mac's cock was bathed in moonlight, and Applejack couldn't hold back another soft moan as she spotted the shimmer of a single drop of precum illuminated by the silvery rays pouring in over the bed.
For some reason, Big Mac always felt the need to protest. Maybe there was some deep seated guilt in the back of his mind – logically, something that felt so good couldn't possibly be acceptable, social taboos aside. The second he felt his sister's body shift he tried to prop himself up on one elbow, knowing full well what was coming.
"AJ—" he started, opening his eyes. He had a second to catch a glimpse of Applejack's face, her soft skin glowing in the moonlight as she opened her mouth and readjusted her position on the bed, leaning down towards her hands–
"Gahh..." Mac caught himself mid groan with a press of his pillow over his own mouth. AJ's mouth, in parallel, found its own means of fulfillment, parting her lips and swallowing the head of her brother's cock as deep as she could manage.
The quiet 'ah' as Applejack took Big Mac's cock into her mouth made her brother twitch. He bit down extra hard on his pillow, but remained silent.
If she could have managed with her mouth full, Applejack would have beamed.
Instead, she closed her eyes and leaned forward, taking in a few inches of the colossal piece of meat pressing against her tongue. Her hands moved along with her mouth's expert attention, making a perfect envelope over Big Mac's cock. Where her hands were not, there was her mouth, parting wide and leaving a gloss of spit over the sensitive flesh as she traced her tongue and cheeks over. Whether through restraint or limitation, she only took four or five inches of Big Mac's length with each bob of her head, leaving her palms to caress the remainder of the sizable shaft. A trickle of saliva poured from her mouth with every other movement of her head, leaving ample lube for her hands as they stroked.
Big Mac groaned into his pillow again as his sister took a particularly deep gulp of his cock, humming and moaning over half of his shaft. The worst of his fears was already coming true – when he was in control of the situation, restraint was possible, but when his sister could go to town unabated and work the most seductive of her talents, his resolve for silence didn't stand a chance.
He needed to distract himself.
Parting his eyes, the perfect target presented itself, bobbing up and down beside his chest.
The moon was the perfect spotlight on Applejack's ass as she busied herself burying inch after inch of her brother's dick in the back of her throat. The silver glimmer caught the brilliant skin-tone of her cheeks and made them shine like an entity of heaven all their own. Applejack's ass was shapely, the perfect amount of round and curvy and soft, and it called to Big Mac's attention like a shimmering spirit in need of affection. The sight of the soft folds just between Applejack's closed legs as she bent herself forward was the extra nudge of invitation in the unspoken request – not a demand made Applejack’s own accord, but simply out of necessity. An ass so perfect was criminal to ignore.
Applejack gasped as she felt her brother's coarse palms slap against her backside. In spite of himself, Big Mac grinned.
Neither party spoke. As Applejack lowered her face back from her momentary lapse in attention, her grip was a little tighter, and the caress of her lips on the head of her brother's member was a little more intense. She dripped out a healthy dose of saliva onto the engorged tip before tracing her tongue along the underside of the shaft, circling all around and savoring the taste of her brother's musk.
It was only through his new distraction that Big Mac saved himself from volume. He clenched his hand tight on the luscious ass-cheek underneath his palm, and the muffled squeal he received was ample encouragement. He raised his other arm up and took AJ's butt fully into his grasp, squeezing and kneading the soft but taut curves of her backside, snorting in an almost primal manner as he squished the still bouncing behind in front of him. After a few good squeezes, Big Mac moved one of his hands downward, tracing his finger through the crack between his sister's cheeks. Applejack shivered as she felt her brother's touch slide over her second entrance – and then gasped as she felt fingers on her first.
Big Mac grinned. His hand was soaking wet.
"Mmh–" Applejack let out a small groan onto her brother's cock, willing herself back to work in an attempt to force the continuation of her attention. But the feeling of her brother's firm, long fingers sliding up and down her dripping slit rendered her completely brain-dead. All she could think about was the feeling of his hand over her lips, spreading her own juices over her already soaking pussy. Her body's reaction had enough presence of mind to draw her front end up, letting her sizable breasts take the place of her ass in the shower of moonlight. Her brother's cock sprung free from her mouth with a pop.
"Ohhh, Macintosh..."
The fingers on AJ's slippery hole paused, one of them just parting her lips and peeking half an inch inside. She could feel herself quivering without restraint, her muscles clenching and begging her brother's hand inside. She wanted him so bad, as badly as she wanted to scream at herself to dive back down and choke on her the giant dick waving in front of her. But her body was a traitor, willing her into immobility, save for the shaking of her hips up and down as she tried to force the touch she wanted so badly.
"Please, Mac, I need it–"
The touch on her wetness disappeared instantly, and the rustle of the bed along with the creak of bedsprings caught her by surprise. She felt her brother's hand again, this time with his left as well – one of them on her shoulder, and the other pulling her up by her chest, wrapped around her frame just below her neck. The feeling of a strong grip yanking her upward drew another moan from Applejack's mouth, but it died before reaching the moonlight as Big Mac adjusted his grip, planting his palm firmly on his sister's lips.
"AJ," he said firmly. The word was quiet, but it punched through the noise that had come before it like a freighter through the fog. Applejack's breathing was the only sound, excited and panting and now with just a touch of apprehension.
"You knew when you came in that Applebloom was sleepin' in the next room, and I knew this was gonna happen if I let you get carried away. If you can't keep quiet you're gonna have to go to bed still feeling like a mare in heat. Understand?"
Applejack nodded wordlessly.
With a relieved sigh, Big Mac loosened his grip.
He caught himself with a half-choked gasp as Applejack threw her hand backwards. Her grip squeezed the length of Mac's cock, jerking it up and down recklessly.
Even though his hand covered Applejack's mouth, Big Mac could tell she was grinning.
Mac moved abruptly, taking both his hands to his sister's shoulders and pulling her backwards. Applejack stifled the 'eep' that might have come were she not on the verge of being sent away without the one thing she really wanted, and she kept quiet as the bed sheets bounced with the force of her impact against the mattress.
Big Macintosh took a moment to admire his sister's body in the cascade of nature's night-time spotlight before he lowered himself over her. His cock stood at full attention, pointing squarely between his sister's legs.
"Ohhh..." Applejack couldn't hold the murmur back. True to her brother's wishes, she kept it as quiet as possible, but even the proximity was enough to make her body tingle. The sensation of her brother's body propped up over her, holding himself up on his big muscular arms, his entire frame large enough to entirely overtake her, or to wrap her up away from the world until it was only the two of them.
The giant rod poking between Applejack's legs made her entire body shake. If there had been anything keeping her awake, it was this. Her sleeping sister be damned, she wanted Big Mac inside her. She wanted to feel every inch of him pounded into her cunt, so big and deep it would be like splitting her in half, and she wanted her brother to ravage her, fucking her so hard she forgot how to speak, and the only sounds left would be her guttural moans, loud enough to wake the whole house–
"You gonna finish before I even put it in, AJ?"
Big Mac was hunched over Applejack's body with the tip of his cock still inches away from his sister’s entrance. Despite the lack of penetration, Applejack was thrashing and arching her back on the bed as though she was already in the throes of orgasm.
Big Mac allowed himself a mischievous grin as his sister's red cheeks contrasted the darkness of the bedroom.
Applejack bit her lip in embarrassment before she collected her words.
"Oh... hush. C'mon and fuck me already, or you're gonna hear me screaming about something else."
Applejack gasped as Big Mac pressed the head of his swollen member against her soaking wet lips.
"You think you can be quiet?" he asked as he slid the tip up and down the slickness of the waiting pussy in front of him. Applejack was already arching her back again. She managed a nod, but couldn't bring herself out of the throes of imminent bliss to make it look even half-sincere.
Against all the logic in his head, Big Mac grinned wider.
"Are you sure?"
Big Mac buried himself in one forward stoke. The hot, wet texture of his sister's hole wrapped around him like a glove, clenching to his length in a perfect fit.
For Applejack's part, she did manage to keep quiet for a second or two.
"Fuck!"
The shout was loud enough to echo off the walls of the fairly spacious room. On the bedside table, Big Mac's lamp jittered with the force of the sonic outburst.
Mac immediately regretted his impish attempted at humor. He sandwiched his hand over Applejack's mouth, though the damage had already been done.
"For Celestia's sake AJ!"
Applejack couldn't speak. Her body was thrashing against her brain's direction, arching and squirming and revelling in the feeling of her brother's cock inside her.
So big. So full.
She had cum the instant she'd felt Mac's head up against her womb, and her body had no intention of letting her stop. Her vagina was twitching and spasming, squeezing the giant length inside her as though trying to milk every last drop of pleasure from the incestuous shaft filling her up completely.
Big Mac, for his part, showed no sign of anything other than exasperation. Buried inside his sister's cunt, he rolled his eyes and pressed his hand harder overtop her mouth, stifling the remaining moans and grunts that followed until AJ's body finally settled itself.
When her orgasm subsided, Applejack looked up at her brother completely awestruck. His hand on her mouth had only made everything feel better. He was so strong, not having the slightest problem keeping her in place and muffling every sound. She could feel the weight of his body through his restraint, and the strength of his grasp as his fingers clasped over her face.
And, more than anything, she could feel the pulsing heat of his giant cock as it filled every inch of her up.
The thought almost made her cum again – but as her body started to squirm in somatic response, Big Mac tightened the grip of his hand and gave his sister a slight jerk to the side. Applejack's eyes opened wide.
Mac's face was the sternest he could muster aside the sensation of his cock buried inside his sister's hole. His brow was furrowed, and a lock of his dark gold-hair danced in front of his left eye.
"I ain't gonna tell you again, sis."
"That was your fault, Macintosh!" Applejack shouted back in a vehement whisper from behind her brother's hand. While her statement was true, even Big Mac hadn't imagined that a simple thrust would cause his sister to scream like a banshee.
"I don't wanna hear it. Keep quiet or you go back to your room."
Yes, Applejack had cum already.
But she wasn't remotely interested in going back to bed yet.
Big Macintosh pulled himself out slowly, prolonging the sensation of withdrawal. Applejack hissed under Mac’s hand as he moved his hips back until just the tip of his length was still inside. After only a second of anticipation, Mac slid himself back inside, not pausing until the full extent of his considerable girth was pressing against Applejack's inner walls.
His hand managed to muffle the moan again, to a moderate effect. He grit his teeth and glared at the squirming nubile body underneath him.
"AJ..." he hissed.
Applejack glared back and pulled her brother's hand away from her face.
"I can't be quiet if you go in all at once like that!" Applejack shivered just from the thought of the twelve inches inside her, but she kept grounded enough to avoid another episode of complete lack of coherence. "You mean to tell me that doesn't feel as good for you as it does for me?"
Big Mac bit the inside of his cheek and turned his face to the side.
"'course it feels good...'
"Yeah, but I don't see you gettin' off from one shove," Applejack admonished, shoving a hand into her brother's chest. "So either go slower, or I ain't gonna be responsible for how loud I am."
"Could have avoided this problem if you'd just stayed in bed..."
"Just shut up and fuck me, you dummy!"
Big Mac sighed. He took pause for several seconds before turning his head back towards his sister.
She grinned at him. He grinned back.
Still all the way inside, Big Macintosh leaned forward and locked his lips to Applejack's. The two moaned together, both of them as quiet as they could manage. Their eyes blocked out the rest of the world, leaving only the feeling of their mouths intertwined, and the perfect fit of length to depth. Both of them moved their hips, grinding their sex together, and the volume of their moans spiked the tiniest bit as they panted and cooed while trying their best to keep quiet.
The kiss went on. As Big Mac lavished his sister in the fiercest passion of his oral caress, he drew his hips back slowly, so slowly he felt sympathy for his sister's outburst. The heat and insistent gasps of Applejack's velvet tongue in his mouth made everything feel more – the way her insides tugged at his shaft as he withdrew made him groan amidst the wash of mutual pleasure, and Applejack echoed him as he pressed back inside.
At his sister's direction, Big Macintosh slid inside, slowly.
Ponderously slowly.
Agonizingly slowly.
He felt it. He had to lift his head away from the kiss, leaving Applejack with her eyes closed and her lips parted, breathing heavily into the spot where her brother's mouth had been. Applejack opened her eyes to catch sight of her big, strong brother gritting his teeth as he pushed forward.
The problem with such meditative movement was that Big Mac could feel every inch of his sister's inner caress as he slid inside. The slick texture of her moisture enveloping him was enough to make his head spin. He caught himself biting down on his lip, hard, as he slid forward painfully slowly.
Applejack fought the mixture of pleasure and giddiness in her head to keep herself from giggling as she stared at her brother's intense expression.
"Feel good, Big Mac?" she asked. Her tone was taunting and sultry.
Big Mac groaned quietly his tip hit the furthest point inside Applejack’s cunt.
"Yes…" he hissed, resting for a moment with the full length of his cock sheathed in the welcome embrace of Applejack's sex. He breathed out softly again as he began to pull himself out.
Where Applejack's eyes had before been fixated on the veil of pleasure and darkness as they closed, now they were focused intently on her brother's face. The expression he made was the strongest invitation she could ask for to play naughty.
"You mean y'all feel good havin' that big twelve inches inside your little sister's cooch?" Applejack asked, dripping seduction from every syllable.
Big Mac groaned, but caught himself halfway through, clamping his mouth shut as he finished pulling out. For want of his own desire finally taking over, he couldn't stop himself from pressing inside again. He managed to break his grimace to part his mouth as the head of his cock was sucked inside.
"Don't start, AJ... remember Applebloom's still in the next room–"
"Applebloom can't hear a thing Big Mac, I'm keeping real quiet. Almost whisperin', practically."
Big Mac groaned again as his sister leaned forward, keeping her hips on the bed but raising her torso upright, letting her mouth rest on Big Mac's shoulder. Big Mac felt his hands trembling as Applejack took them in hers, and guided them to her breasts, pressing her brother's fingers into the soft, yielding flesh.
Mac just held himself back from a muffled whimper.
"I can feel how hard you are, Mac. I know you love it when I talk dirty... when I let you fuck me and whisper in your ear how bad I want you to fill me up with your cum..."
"Celestia help me, Applejack, if you don't stop that..."
"What, big brother? If I don't stop soundin' so sweet in your ear," Applejack paused as she interjected a light lick along Big Mac's earlobe, "you're gonna spray your load inside your sister's stomach, until it's leaking out all over the bed?"
Mac's fortitude was herculean. He'd managed two more glacially paced thrusts as his sister urged him on – now he had to stop. He could feel the veins along his shaft twitching as his sister's cunt massaged his length.
"If I cum..." he started, breathing heavily as though holding a great weight with only the strength of his shoulders. "...if I cum, will that have you tired enough to go back to bed?"
Applejack considered her response.
The scrunch of her mouth and tiny flick of her eyes gave her away.
"Yes," Applejack lied.
"Horse apples. Then I ain't finishin' until you're worn out."
Drat.
As much as she wanted to take a full load of her brother's sperm, Applejack knew what kind of effect it would have on her – the thought of bursting at the seams with cum, her brother's cum, was enough to remind her that the real thing would have her wanting even more before she was ready to roll over and go to sleep. Her brother's cock felt good now, but seeing him on the edge of climax in such an agonizing fashion forced her focus onto something other than her own pleasure. And she wasn't sure if she could get off as much as she needed while Big Mac was flirting with his own orgasm...
So what was the solution?
The idea sprang into Applejack's head as Big Mac's head popped loose again, just the very tip of his cock still inside her.
"Mac," she said.
Big Mac broke his focus of concentration and opened his eyes, looking towards his sister as she stared up at him.
"What?"
"I can think of something that'd get me to sleep."
Quietly, with only the sound of the pair’s breathing and the soft rustling of sheets underneath her arm, Applejack reached her hand below her legs and took hold of Big Mac's cock. He gritted his teeth as he felt his sister's palm against his sensitive glans.
Slowly, Applejack guided his head downward just an inch, and then pushed it ever so slightly forward.
"AJ–"
"Please, Mac! I promise, I'll roll right over and start sawin' logs if you–"
"Ain't gonna happen." Big Mac countered his sister's objection with his own, staring earnestly into her eyes. He didn't move his hips, but he felt his sister's attempts to push forward and have him slip inside her back door.
"And why is that? Don't pretend that you don't like it."
"Nothin' to do with me likin' it. That's the whole problem – I know that you like it too much. And if I slide in and start fuckin' you in the ass–" Applejack shivered with her brother's description and tried in vain to jostle her butt forward "–I know you're gonna start screamin' and wake the whole house up. And the next thing ya' know, Applebloom's standing at the door wondering what you're doing naked in my bedroom with my cock inside you."
"You sure know how to disappoint a girl, Big Mac," Applejack sighed.
"How about a compromise then?"
Without warning, Big Mac took hold of Applejack's shoulders with both hands and pulled her up from the bed. The blanket flew off with the force of his motion, landing in a pile on the floor.
"Woah! Mac, what are you–"
Applejack's question drowned in her brother's mouth as he kissed her, still holding her completely in the air. Applejack met the gesture with her own reciprocation, and moaned softly into her brother's tongue as he held her aloft with his amazingly muscular arms. She only had a second to revel in the kiss before the pair of sturdy working appendages yanked her around in a circle. Applejack stayed upright, but her brother shifted position, turning over and taking Applejack's place on the bed. As he settled, he loosened his grip on AJ's shoulders, letting her rest on his legs.
"I know you like this too," he said, pulling her further up.
Applejack grinned as her slit slid over the stiff rod underneath her.
Big Mac loosened his grip further, and Applejack placed her hands on her brother's chest, raising her hips as she did so. She could feel Mac's cock spring up to meet her, but didn't feel the tip until she had lifted her backside almost completely perpendicular to the bed. The size of the object waiting to fill her up was fully apparent as a result, and she caught herself shivering as she reached a hand between her legs to line up with her brother.
"You remember to be quiet now," Big Mac chided, unable to hide his grin.
Applejack didn't tender a response.
Instead, she slammed herself down on her brother's dick, taking the full length in a single drop of her body. The plunging sensation coupled with Big Mac's size felt like she had been speared by a long, thick, amazing length of flesh. To her surprise, she managed to keep mostly quiet – but she couldn’t help from grasping at her own tits, slapping them louder than was advisable as she ground her hips against her brother's crotch.
Mac couldn't bring himself to pester his sister any longer. The only words left were in his head. Celestia, she felt good.
He was the quiet one most of the time anyway – but now, if not for the sleeping sibling one bed over, Mac would have shouted loud enough to rattle the windows at the feeling of his delicious sister's pussy swallowing every inch of his cock. The way she gyrated her hips and pressed him against every corner of her insides – he'd thought the change in position would give him time to recover, but it was quickly apparent that might not be the case.
Neither of them spoke. Applejack breathed out in a single sound as she pulled herself up. Her arms weren't strong enough to bring her up off the full extent of her brother's dick, so she contented herself with half-way before she slammed her hips back down. Miraculously, the bed only gave the softest squeak of springs. Mac and AJ tried to match their mutual whimpers to the frequency.
Each time Applejack lowered herself she picked up speed, and within a moment she was full on fucking her brother, just the way she'd wanted. The bed threatened to do the groaning for them, but both brother and sister managed to keep relatively silent. Big Mac focused his attention on the bed sheets, grinding his fingernails into the fabric and clenching his hand around a protruding patch of material. Applejack mimicked her brother's actions, but used her tits in place of fabric, slapping her hands against the soft globes of flesh and raking her fingernails across her own nipples.
After a few minutes, Applejack could feel her brother's closeness again. She could feel it in the way his hips jutted awkward erratically to meet hers, and the way his cock twitched in longing every time the head pressed against her womb. She could tell because Big Mac was muttering under his breath, the only time he was sure to fail to hold back the slew of dirty words that AJ found herself drawn to in excess.
But she wasn't close yet. She was getting there, and she finally felt full and exhausted enough from the cowgirl session that she guessed she could let her brother sleep when she came.
So what to do?
Applejack planted her hands firmly on her brother's chest and straightened her legs as she lifted herself up. The slick sound of her wetness gliding up her brother's shaft drew a sharp 'oh' from Big Mac, which she reveled in – but she didn't stop until she was all the way up, practically standing overtop the full length of slippery cock at full attention underneath her.
Big Mac didn't open his eyes until he felt his sister's finger tap gently on his chest.
Applejack’s other hand moved between her legs faster than Mac could react to.
"Big Mac," she said, sliding herself just ever so slightly forward, "remember to be quiet."
Big Macintosh felt the tight ring of his sister's asshole for just an instant before she plunged downward again.
Against all logic to the contrary, both brother and sister kept silent but for a single gasp as Applejack lowered herself, sliding every inch of her brother's sizable cock inside her ass. They both felt the difference. Tighter. Softer. Sinfully better.
And yet neither of them spoke. An almost complete silence enveloped the room as AJ's back entrance enveloped twelve inches of her brother's hardness. She allowed herself a tiny 'mph' as she bottomed out, planting both hands on her brother's chest and arching her palms, digging her fingernails into Big Mac's skin.
Both of them took a moment to collect themselves, keeping their minds away from the gravity of their position. Applejack's taut cheeks were wrapped around her brother's cock. Big Mac's dick was fully inside his sister's ass.
Heavy breathing took over the sound of bedsprings for half a minute.
Applejack broke the silence.
"Big Mac..."
Mac managed to lift his head, running his right hand through his hair in an almost exasperated overload of pleasure. He couldn't bring himself to speak.
"...you ready to cum?" Applejack panted.
Both of them breathed in.
"...yeah."
Applejack pulled herself up two inches before she felt her brother's cock twitch inside her ass.
"Mac!"
"AJ!"
The two siblings’ moaned each others' names as their mouths met, leaning together and moving their hips in unison. Applejack slammed herself in one inch bursts against her brother's crotch, and Big Mac arched himself halfway off the bed as he met his sister's thrusts, burying himself in her deeper than seemed possible. Applejack clenched tight around the giant length of hot flesh inside her. Her pussy spasmed as she came, matching every other muscle in her body as she completely lost control, thrashing and jerking erratically as she fucked her brother with her ass over and over.
Mac came with a long groan, shooting what felt like a gallon of cum inside his sister. He could feel the splash of his own semen dripping over the velvet furnace of his sister's ass and back onto the head of his cock which met every spurt with another. His eyes clenched so hard his head felt like it might explode, and his hands scrabbled at the bed as his cock jerked, spraying more cum, coating every inch he couldn't see with white.
Applejack kept cumming. While her brother's orgasm was tangible and finite, hers came and didn't go away. Her clit felt like it was on fire, and her hands lost all sense of placement in relation to her body. She wanted to grab at her own tits, but couldn't find the presence of mind to move her hands. She wanted to rub herself into a stronger climax, but her body told her that wasn't possible. Eventually, her hands settled erratically on her brother's chest, which she grasped at like a victim overthrown from a lifeboat, clinging to the soft hairs protruding from the muscular mass underneath her touch.
"Ohhh...." she finally whispered, her volume understating to its fullest extent the ferocity of her climax. The feeling of her brother's cock softening in her ass made her shiver.
Big Mac and Applejack drank in the silence, parted only by the sound of their breathing as they descended from the height of their pleasure.
Eventually, Applejack stood up with some difficulty, her legs shaking against her instruction as she lifted off her brother's hips. He popped out of her with a profane 'plop', and a trickle of the mass of white liquid he had unleashed followed, leaking out from between Applejack's glistening perfect cheeks.
Applejack shivered and fell forward, landing with a soft thump against her brother's side. She managed to turn towards him, despite her body's insistence that every muscle was to shut down. Big Mac met her with a hand on her cheek and a soft peck on the lips. Applejack smiled at him as her eyes started to close.
"Sleep tight, AJ."
Applejack murmured softly.
"Love you...."
The last syllable escaped into silence, blanketing the room as Applejack fell to sleep in an instant.
Big Mac allowed himself a low, contented sigh before he wrapped his arm around his sister. The feeling of her hot, naked flesh under his hand precluded the need for a blanket, but he reached for the remaining cover regardless and threw it over his shoulders. He brought the fabric only up to Applejack's waist – she always complained of being too hot when covered up completely.
"Love you too 'sis," he whispered, planting a kiss on Applejack's forehead. The tendrils of sleep crept over him in short order, creeping from his sister's beckoning heart and drawing him close until the pair were both snoring softly, entwined and locked together like two pieces of a locket: perfectly matched halves of a single heart bathed in the moonlight.
The soft snoring carried faintly through the night, buoying in the air and through the soft silver rays until it crept between the cracks in the wooden structure of the wall into the room next door, announcing the peaceful slumber to the only person listening.
Panting, Applebloom drew her hand out from between her legs, soaking wet.
"I hope they didn't hear me," she whispered to herself.
