Crime And Punishment

The day had been long, and Big Macintosh was enjoying well-deserved rest, or trying to. He had no sooner tucked Applebloom in and crawled into bed himself than he heard bedroom door creak open.

There were only two ponies that might sneak into his room at night, for very different reasons. He knew who this was when they made sure to lock his bedroom door before approaching the bed. That wasn’t someone that was coming over to complain about having a nightmare. It was a good thing she’d gotten into the habit of locking the door; it had been very awkward for Applejack to hide under the sheets the last time they were interrupted by Applebloom.

Mac rolled toward the door to see Applejack creeping onto his bed with her best bedroom eyes, that expression that said ‘I’m not thinking with my brain.’ Typical mare; always horny.

“A bit tired tonight, sis,” Mac muttered, “Ya know how-”

Applejack put a hoof on his muzzle to quiet him, then slowly crawled beneath his covers. He couldn’t help but take a deep breath of her scent when he realized she’d gone into heat. That settled it; he wouldn’t be able to pry her out of his bed even if he wanted to.

“You kin be as tired as ya want,” Applejack slid close, her toned body feeling warm against his, hooves gently coaxing him onto his back, “Ya ain’t gotta do nothin’ but lay back and enjoy.”

She climbed atop him, having to practically do a split to get her hind legs around his larger frame, but he wanted to at least getting a taste of her heat before that started. He grasped her hot plot in his front hooves, tugging her toward his face. She got the idea and chuckled, leaning forward to balance against the headboard as she sat on his face instead with practiced ease.

Either she tasted better than ever, or he was hornier than he thought, because he rolled his eyes back from the first delicious drop on his tongue. He squeezed her rump as he pushed his muzzle against her, prying her labia apart with his tongue as he ground his nose against her clit. She shivered and bit her lip so as to not moan too loudly.

Needless to say, his body responded as well, thick sheath filling out rapidly before his tip escaped. Applejack swiveled, turning herself about on his head before leaning down to his crotch. He felt warm lips slip over his tip and that wonderful tongue work over him as he was tongue-scooping out thick mare honey. She let his shaft expand, swallowing it as it reached her throat, barely gagging as her neck expanded with his size. Celestia he loved that throat.

It had taken her a long time to be able to do that, given that he was the largest of any stallion he knew. He’d actually had interested mares change their mind when they saw him at full staff, afraid that it’d hurt. In fact, Applejack was one of only two mares that had ever taken him ‘belly-deep,’ and the other may have only let him because she was only capable of answering ‘mmhmm’ when asked if she was okay.

Soon, he wasn’t satisfied with just her throat, as talented as it was, so he took one more lap, gargled her apple juice playfully, then coaxed her back downward. She was happy to turn around to face him and sit her sopping wet slit against his saliva-covered shaft.

At this point she paused, blushing hotly, something she hadn’t done in a long time.

“Uh, Mac,” Applejack whispered, “Ah haven’t taken mah foal control...” That would explain why she tasted better than usual.

“Enope?” Mac breathed heavily, barely able to stand the heat of her perfect pussy against his shaft.

“No, ah didn’t ferget,” Applejack blushed more, “Ah was actually hopin’… we could not use that… this heat.”

Mac blinked. It wasn’t the first time she had indicated she wanted to make a foal, as ridiculously taboo as that was, but it was the first time she’d gone through with not taking a prevention potion beforehoof. His muzzle hung open without responding, though she generally knew what he was thinking with minimal communication.

“Ah was thankin’,” Applejack muttered, looking disturbingly adorable when flushed head to hoof, “Ah could just say that it’s a stallion from town and that ah had… agreed not to let anypony know who. Wouldn’t be a lie, right? Yer in this town and ya don’t want me to let anypony know.”

It was like her to spring this question on him while he still had her taste on his tongue. He definitely should say no.

“Eyup,” Now Mac was blushing, not that it was apparent with his red coat. He’d always wanted this as much as she; the problem was what other ponies would think, much less her family should they find out. Still, there was no reason for them to suspect them, since they had been careful not to display their feelings publicly.

Applejack rolled her hips smoothly, the only sound in the room the moist slide of her lips against his pulsating length. Her juice was making a puddle on his belly. He slid his hooves to her hips, feeling her muscles tense with her movements before tugging her to place his tip snugly at her entrance.

Mac’s blood flooded with chemical emotion as he felt the familiar slickness sliding down upon him, gliding over each bump, ridge, and vein. She fit flawlessly. Their society said this was wrong, but neither of them understood why. It felt so perfect, as if this cock and cunt were molded specifically for each other.

“I love you,” Applejack whispered, leaning forward and kissing him, her body encompassing him. Her belly finally pressed firmly against his, her soft rump sitting gently against his balls.

“I love you,” panted Mac in return. That was something he never abbreviated to ‘yep’. His beautiful sister deserved no less.

She rolled her hips against him again, pulling up and down, slick lips flexing out as she pulled him outward and pushing inward when she pushed him back inside. As tired as he was, he couldn’t keep his hips from moving in response, breathing heavily and enjoying a deep kiss with her, tongues playing together eagerly as they stared into each other's eyes. They didn’t break the kiss; it helped muffle their moans.

For now, there was nothing but one another, the lewd sound of their increasingly moist bellies smacking together, the slurping suction of Applejack’s lips being tugged up and down with the slick friction, so loud that it was a wonder that that alone didn’t wake up Applebloom in the next room.

The only reason that Mac could hold his load for more than 30 seconds was how much practice he had with Applejack. Applejack was lucky to be a mare though, as she didn’t have to hold hers in, nor could she in her current hormonal state. He was barely inside before her wet flesh was convulsing around him, milking him, her body desperate to wring out all the fertile seed it could get from those heavy balls.

Mac couldn’t tell if she was having a lot of orgasms or if she hadn’t been able to stop the first one and was just riding it through the whole act. The lack of foal control seemed to be making her all the more spastic, body shaking with the effort to not squeal in delight. She had never actually had sex during a heat while not repressed with infertility potions, and clearly her brain was having a hard time handling it.

Applejack looked to be enjoying it to the point she was barely sentient. She was a mare though, so using her bits and brain at the same time was hard enough even in lesser circumstances. Again, not as if Mac minded, and he was barely keeping coherent thoughts in his head himself.

He hammered his hips up at this point, bouncing her against him, and slid his hooves from her hips to her breasts, swollen due to her hormonal state, so he pushed against her and slid his hooves in circles around her nipples, enjoying how the spongy flesh gave at his touch, then rubbing into her nipples themselves, making her squeak, her eyes actually tearing up from the intensity of the pleasure. He couldn’t stop thinking about how this beautiful flesh would feed their foal, and he himself was looking forward to getting some mare milk from the tap once she was nice and milky.

He started to get dizzy from the pleasure furnace that he was lost in, just letting his body move on instinct while he enjoyed. Their muzzles were still pressed together, though it was impossible to play their tongues together since both of them had clenched their teeth in an effort to not scream like a cart of filly guides careening down a hill. Their kissing at the moment consisted mostly of their teeth crashing together with each buck.

Mac arched his back, every muscle tensing, pouring sweat so much that he was leaving an imprint in the sheet beneath him. Applejack was sweating just as much, to the point that it was visibly dripping from her matted chest to his. His thrusts became uncontrolled and out of sync, just trying to keep up with the rapid slamming of his sister atop him.

“That’s it brother,” Applejack moaned quietly, easily able to tell that he was about to give her insides a coat of white paint, “Time ta buck yer little sis fulla foal… oh Mac ah’ve dreamed about this ever since ah kin remember.”

This voice of his sister encouraging him to knock her up was easily the hottest thing he had ever heard, and he went over the edge harder than he ever had. Balls tensed up as he fired off a hot geyser of fertile seed into her. She clenched down on him hard, determined to not let a single drop escape. He shook uncontrollably, but she didn’t stop slamming her body against him, pumping every drop, her whimpers seeming to go up an octave with each new blast. Her belly began to swell, more than it already was from his girth at least, as he flooded her ready womb, not leaving a single fleshy corner not drenched in his sperm.

Oh Celestia, he was really doing it; he was finally impregnating his ridiculously hot sister! The first stallion to get the privilege of making a life with her. He couldn’t wait to meet their foal, and to put another inside her if this went well enough.

Her hips slowly ceased once he had emptied himself, and she lay against him still for a moment, giving him another kiss as they cradled each others head. Pulling herself belly to belly with him, they let their perfectly fitted parts throb against one another as they pulled close.

Their incestuous lust stated, they enjoyed a moment of looking into each other's eyes, nothing but pure love shining through for one another. Mac so wished she wasn’t his sister right now. He’d love to be able to kiss her in public or even plow her in public in places where it was allowed like the park. She lay her head on his chest and sighed, clearly wanting to sleep with him still tightly fitted inside her, but they couldn’t; it’d be too hard to explain why she was coming out of his bedroom the next morning.

So they shared one more kiss before she pulled off of him with a long, lewd slurp and headed to her own room, body shaking and his foal batter still drooling down her thighs.

<-------------------------------------------------------------------------------->

It was ten months into her pregnancy, and she couldn’t be happier about it, even if she couldn’t properly show it.

Everypony bought her not wanting to tell whose it was; having a foal out of wedlock was acceptable in a society where fewer ponies bothered to marry than didn’t.

Applejack tried to get around more, since previously she had done so less than the average mare, wanting to support the idea that it some stallion’s in town. She probably should have started that before Mac planted it.

She’d encouraged Mac to be more open to mares jumping him, to provide distraction from any idea that Applejack’s might be his. He had done so, though Applejack had to admit it made her jealous, especially when she realized her best friends were having goes at him. Starlight recently complained to Applejack about racket Twilight and Mac made the night before. Applejack wondered if she maybe shouldn’t have encouraged him so much, but didn’t want to seem possessive.

Applejack felt the need to ensure that he remembered whose he was, even if it was late in her pregnancy to be doing this. She went into the orchard where he was working, as she was sure Applebloom was off with her friends, and Granny never walked out this far into the orchard.

He perked his ears when she approached, making her chuckle. No doubt he was worried about her walking so far in her condition.

“Ah’m okay,” Applejack said, “Just felt tha need to mark mah territory is all.”

Mac shifted a hoof a bit at her honesty, perhaps feeling awkward at the realization that she might be envious. Knowing him, he felt worse than he should.

“Don’t be that way, ya know it’s alright,” Applejack encouraged. “Anyway, be gentle, but ah want mah brother’s hot dick in me all the same.”

Applejack wobbled about to face her plot toward him, flagging her tail up to reveal both a moist slit and swollen teats, packed tightly behind that firm round belly where their foal currently resided.

He didn’t mount up immediately, instead stepping up and taking a deep breath before sliding his head down. She expected him to take give her slit a good licking, but he went lower instead, pushing his lips against one of her nipples, slurping rather loudly and mm-ing a bit at the taste. Applejack smirked, wondering how long he’d wanted to do that.

She spread her legs, letting him get his feel, and it definitely didn’t feel bad, though at the same time Applejack was in a randy mood, so politely grasped his neck in her tail and coaxed him upward. He chuckled at her eagerness, though instead of mounting her outright, he sat on his haunches and pulled her back to do the same, letting his sweaty chest sit against her back and licking at one of her ears.

She pushed her rump back as she felt his solid shaft against her, not wasting any time before sliding it down to snug against her slit, pulling her down immediately. She needed this, already as slick as if they had already had a half-hours foreplay, and encompassed that thick girth within her, feeling the stretch that she could only get from him.

She moaned, arching her body against him as he entered, not thinking her clearest as she tried to push back as deeply as she could. Mac had chosen the position it seemed to make it easier for him to not go in too deeply though, to his credit being very careful that her eagerness didn’t become a problem. All the same, he groaned, rolling his eyes back as he lay his muzzle against her shoulder.

Applejack slid her front hooves back as he held her, stroking over whatever part of his incredibly hot body she could reach. His hooves slid down to her breasts, rubbing into them, so plump and ready for their foal that they leaked from the slightest pressure. He bathed one hoof in her milk before raising it to her lips and letting her lick it off. It was sweeter than she expected, though unsurprisingly tasted like apples.

Soon their bodies were rolling together. Though the sound of the moist penetration wasn’t as loud outdoors, their moans were. It was rare that they didn’t have to stifle their moans; maybe they should do this out here more often. For once she let herself squeal in a pitch very unlike her, and Mac continued to lick at the back of her head, his own groan practically vibrating through her head.

They took it nice and slow, Big Mac backing off every time he felt her pussy tense up as if making her stave off her orgasm as long as he could, but she didn’t mind. It would only feel better if he denied her for a while. For a while she just enjoyed him inside her, every familiar curve of his shaft stoking her flames. She knew that cock better than any other mare could, she’d felt it grow from respectable when he was a teenager, to the massive stallion tool that it was now.

She wrapped her tail about his hips, both to grasp his tail and to feel the wonderful movement, loving how his powerful muscles tensed as they made love.

His shaft throbbed hard; she could feel that he was nearing his peak, about to blast his incestuous load inside her as he had hundreds of times before. He sped up his thrusts, and she let herself go as well, clenching her teeth and eyes, but screaming a moan at the same time. Mac groaned as well as his shaft blasted into her convulsing honey hole, letting it run down both their thighs as it overflowed.

“Nggh, that’s mah slutty brother,” Applejack moaned, “Pump mah pussy full while yer foal kicks its cute little legs… so close now.”

Suddenly Big Mac stopped. Not the slow stopping they usually did, but instantly. Applejack looked behind her at him, realizing that he was looking off to the side into the bushes nearby. Following his line of sight, her heart sank as she saw Applebloom, peaking out from behind a nearby tree with wider eyes than Applejack had ever seen on her.

“Applebloom!” Applejack gasped, “This ain’t… well it is what it looks like but let me explain.”

Of all the ponies to catch them, why did it have to be her little sister?

“Applebloom please,” panted Applejack, “Kin we just agree not ta tell?”

“That foal is…!” Applebloom looked more sick from thinking about it, putting a hoof on her muzzle, “Applejack! Yer askin’ me ta lie!”

“No!” Applejack rationalized, “Just… don’t say anythang is all.”

“You told me that was lyin’ by omission!” Applebloom shot back, and she was right. “This is gross! I’m tellin’ Twilight!”

Choosing Twilight meant that Applebloom didn’t simply think it gross, but also realized it was illegal. Her sister was about to turn them in to ‘the authorities,’ and Applejack was ashamed that that was her best friend.

“Wait!” Applejack sighed, “At least let us go with you and explain.”

“I don’t even want to be around you!” screamed Applebloom before running toward Ponyville.
