Blooming Big Macintosh

Apple Bloom lay in her bed, tucked tightly beneath the cozy, comfortable warmth of her blanket, but her eyes were wide and awake. She gazed out her window, watching the apple trees in the orchard, weighed heavy with leaves, swaying ever so slightly in the breeze. They were silhouetted by the bright light of the moon, casting a peaceful white glow upon the dark landscape. She knew she needed to rest, but both her mind and body were still rushing with energy. She let out a small huff of both boredom and annoyance, and then rolled over onto her stomach. She forced her eyes to fall shut and buried her muzzle into the soft cushioning of her pillow.

Before she was even able to think about sleep, her ears pricked up to the oddest of sounds. They swiveled and scanned for the direction of the noise as she lifted her head from the pillow, blinking. Applejack was still out saving Equestria with her friends, or something of the sorts, and Granny Smith’s long, drawn out snores of heavy sleep could be heard coming from her bedroom. The only pony awake in the house was her older brother. Although at first, the noise sounded eerie and unusual, she quickly realized that it was in fact Big Macintosh’s voice making it. The only problem was that it seemed to be moaning.

Even more awake than before, she quickly pushed back her blanket and crawled out of her bed. She wondered if he was sick, in pain, or having a nightmare. No matter what the cause of the moans, she knew she must help. Besides, investigating the curious sound was a good way to pass the time. She noiselessly creeped across the floor of her room, her small body making such a feat seem easy. She then opened her door and crossed the hall to the opening of her brother’s bedroom.

As she did so, the young filly quickly realized that these moans were nothing close to those of pain or a fearful dream, but instead resonated happiness and pleasure. Although she knew her brother was safe and sound, even enjoying whatever it was that he was doing, she was still curious to see exactly what that was. She smirked, noticing that the door was cracked ever so slightly, the warm glow of a lamp pouring out. She paused before taking a step closer, feeling something stirring deep inside her. It was a feeling she had never before felt. It was a fluttering, a tingle, but not that of fear or from the rush of excitement, not from the possibility of getting caught, but something else. For the time being, she decided to ignore it, her curiosity getting the best of her. She cautiously and lightly stepped closer to the crack, and then peered inside.

As she did so, she almost gasped, but caught herself just before doing so. Big Mac sat atop his bed, his legs spread wide and one of his hooves wrapped around his stallionhood. That was not even the oddest part though. His stallionhood looked completely different than she had ever seen it before. It was tall, massive, and looked to be rigid and stiff. From what she could tell, it was not only much larger in length but in thickness as well. The feeling inside her was slowly growing.

She watched curiously and silently as he moved his hoof up and down the stallionhood’s surface. These motions that he made were what seemed to be causing his pleasure. He would moan and pant softly with the movements, sometimes even shudder. Her body was completely still besides a slight shivering as she watched with thorough concentration. She wondered exactly what it was that he was doing, and why he was doing it, besides the creation of pleasure, that is. She had never before seen anything like it. It was confusing and seemed to make little sense to her. She noticed that on occasion he would spit down onto his stallionhood or into his hoof. This seemed to make his movements smoother, easier, and cause even more pleasure.

As she continued to watch and observe, Apple Bloom began to realize how nice it was to see her brother so happy as he enjoyed himself. She wondered if this somehow related to the strange but faint feeling inside her. Was she sharing this happiness, or was it something else, something more? She was glad, very glad if the increasing sensation inside her was telling her right. There was something about the way he moaned and panted, the soft tint of pink on his cheeks, something that seemed to strengthen the sensation within her. She was not only sharing his happiness, but some of his pleasure as well.

As she continued to watch, she soon realized how much she wanted to help her brother out. She wanted to be the cause of his happiness and pleasure. She wanted to do the motions for him instead of him having to them himself. Big Mac was a great brother, and she wanted to show him her appreciation, and how much she cared for her family. At the same time, she doubted such a decision. In a way, it seemed to be as if Big Mac was keeping such a thing hidden. It was a secret of his. He not only waited until Applejack was gone, but until once he thought she and Granny Smith had fallen asleep. She began to wonder if she should even be watching at all. Was it wrong of her to do so? She figured it would be best if she went back to bed and pretended nothing ever happened that night. Whatever the sensation inside her was though, was not only growing stronger and stronger, but was telling her to go in.

Applejack had always told her that instinct and gut feelings were almost always right, and although the feeling inside her was somewhere much deeper than in her gut, it was still something instinctual, something primal. She had made her decision and barged in.

Big Macintosh jumped at the sudden appearance. He let out a stunned yelp as he quickly and shakily attempted to cover his crotch, at first with his hooves and then with his blanket. “Sh-shouldn’t ya b-be in bed, sis?” he asked, his voice shaking as much as his body. “W-what’re ya still doin’ up, huh?”

Apple Bloom’s face grew bright red as her sunset orange eyes turned down to the floor in both shame and embarrassment. She had never meant to surprise him as much as she had, and she now knew that she certainly was not supposed to have seen what she did. “Well, ah, uh, ah heard somethin’ comin’ from your room, and ah wanted to check up on ya and make sure everythin’ was okay,” she admitted. “Then, ah, well, ah saw what ya were doin’. You seemed to be enjoyin’ it and ah guess ah just wanted to be a good little sister and help out.”

Big Mac’s eyes were already wide with shock, but seemed to grow even wider at what she had said. “But… you’re my sister… mah little sister. You can’t be doin’ that.”

“…Why?” she asked, her eyes moving back up to his.

Her brother paused, struggling to find the words to explain such a thing. Watching her brow furrow, he realized that he simply could not explain such a thing easily. “Ah… welp… it’s just wrong,” he muttered.

“But why?” she asked again. He shook his head softly, wishing that what he was experiencing was just a dream. “Ah think it’s the right way to do things. How could havin’ a little fun with your brother and showin’ him how much you love him be a bad thing? Ah watched what you were doin’ for a while there,” she admitted with a sheepish smile. “Ah know what to do for the most part. Just lemme help ya. Please?”

“Nope.”

“But, Big Mac,”

“Eenope.”

“Mac please.”

“Nope, go back to bed, Apple Bloom.”

“Ah don’t wanna. A wanna stay up and make my brother happy.”

“Ah’ll be fine on my own. Go to bed.”

“Maaac!”

“NO.” Apple Bloom could sense her brother’s words growing fiercer by the second. She would have normally given in at this point, especially in fear of angering him, but whatever it was inside her was forcing her to continue. She desperately wanted to help him, to touch him, to make him moan like he had for himself.

“Big, Mac, just please, please, please… pretty please, lemme play with your stallionhood,” she begged with wide, pleading eyes and her lower lip pushed out in a pout. “You’d make your little sis so happy, and ah know ah could make you happy too… please?”

“Apple Bloom…” As the two continued to argue, thoughts of what could happen, how things would play out if he said yes began filling Big Macintosh’s mind, and clouding his judgement on the matter. With his sister’s persistent arguing which he could tell would not let up anytime soon, along with the taboo thoughts of his little sister filling his mind, he was finding it harder and harder to refuse.

“C’mon…. just please,” the filly begged once more.

“….O-okay, you win, sis.”

“What? Really?” Apple Bloom gasped with delight. “Ya mean it? You’re not jokin’ or anythin’?

“Nope, better get started before ah change my mind…” Apple Bloom gasped once more and excitedly hopped up onto the bed with her brother. He smiled nervously as he pushed himself up against the bed’s headboard and hesitantly spread his legs. Gazing down between them, she noticed that his stallionhood was not as hard as before and had shrunk slightly smaller.

“Um, why’s it not big and stuff anymore?” she asked curiously.

“Cause it gets that way when ya play with it.”

“Oh…. okay,” Apple Bloom said with a gulp. The realization that she may have gotten herself in over her head finally hit her. She barely knew anything about how stallionhoods worked, and what he had just said proved it. She began to worry if she could play with it correctly or not. She did not want to let her brother down after how persistent she had been. Big Mac watched his frozen sister curiously and compassionately.

“It’s okay. Ya don’t have to do it if ya don’t wanna. It wasn’t a good idea in the first place. Ah shouldn’t even be-”

“No, Mac,” she quickly interrupted. “Ah wanna make ya happy.” Her face grew red as she smiled, crawling between his legs and gazing down upon his stallionhood. Just the sight of it made her insides tingle. She gulped again, attempting to swallow any hesitation she had left. “Should ah spit on it like you did?” she asked, her eyes moving up and down his shaft.

“Eyup,” he said softly and weakly, giving his little sister a nod. She gathered a ball of saliva in her throat before spitting it out onto his cock. Big Mac moaned softly at the sensation of its warmth. The feel of someone else’s warm, wet saliva dripping down his member, especially the taboo of it being his sister’s was more than enough to harden him up again. Apple Bloom watched in amazement as his cock grew to its full length.

“Whoa… it’s so big…” she muttered. She shook her head and remembered what she was there to do. She slowly and hesitantly wrapped both of her hooves around his large stallionhood, his soft moans and grunts encouraging her to continue. With it in her grasp, she could feel it ever so slightly pulsating and pushing against her hooves. Slowly and hesitantly, she began moving her hooves up and down her brother’s shaft, mimicking what he had been doing earlier with one. Her tongue pushed out of her mouth in concentration as she tried her hardest to perfect her movements. She felt intently as the soles of her hooves moved across the soft skin of his stallionhood and pushed down just ever so slightly, feeling the incredible hardness beneath. “Am… am ah doin’ it right?” she managed to mutter, moving her wide, round eyes up to her brothers.

“Ee…eyup,” Big Mac responded with a slight gasp of pleasure. “You’re doin’ great, sis, but there’s not no reason to be so gentle. Ya can go a bit faster… and ya can squeeze a little more… just not too much.” He placed his hoof atop her head, the two being nearly the same size, and began to stroke it gently down her mane in a simple brotherly act of comfort. His cheeks grew redder than his fur as he began to blush, the act of what he was doing with his own innocent sister finally sinking in. He knew how wrong it was, and how he was abusing Apple Bloom’s young mind for his own pleasure, but something about the thought of it made him crave more. Besides, his sister wanted to show him her love by doing exactly so.

His thoughts turned to pleasure as Apple Bloom did as he asked. She first sent another wave of her warm saliva pouring down his shaft, feeling his skin beginning to tug slightly as her hooves rubbed against it. She then began to rub more vigorously, faster, and squeezer tighter against his hardness, just as he had asked. Big Mac’s hind legs twitched as the pleasure his sister gave him rushed through his body, and she could feel his cock rushing and pulsating against her hooves yet again. “Am ah doin’ good?”

“Uh...huh… eyup,” Big Mac moaned, his hoof pausing atop her head and pressing down on it slightly. “You’re doin’ just perfect, AB.”

“Good as you were doin’ to yourself?”

“Heh… eyup… even better,” he muttered between his heavying pants. The compliment gave Apple Bloom enough courage to begin to experiment and explore. She giggled softly when she moved her hooves up to his large, flat tip, and it flinched sensitively to her touch. Big Mac smiled and nodded, encouraging her to continue. He wanted her to be as comfortable as possible, even if he was still quite nervous about the whole situation. She then glided her hooves all the way down to his base, passing over his slightly sensitive ring and down his widening lower shaft. She watched curiously as his balls pulled up slightly in their sack. She moved a hoof down to them and prodded gently, feeling his scrotum tightening at her touch and the large, marble like objects inside. Big Mac let out a soft grunt as she continued to play, telling her that touching there felt good as well. As she continued to gently prod and play with his balls, she used her other hoof to start stroking up and down his shaft again.

His moans seemed to grow louder with the combination of two sensations. She watched in joy as his stomach began to move in and out, his breaths growing deeper and faster. She smiled awkwardly as her own stomach began to churn and flutter, but not in a bad way. Along with that, she could feel the strange sensation that had been inside her since she first heard his moans, growing stronger and deeper. It felt good, amazing even. It seemed as though the more pleasure she gave her brother, the greater and better the feeling grew.

She smirked playfully as she began to rub even faster, returning both of her hooves to his shaft. “How about this?” she asked, her smirk growing.

“S-sis…” Mac muttered barely able to speak through the soft, quiet moans exploding from his mouth. “…keep goin’. That’s even better.”

“Yay, ya like it,” she cooed softly, giving his cock another soaking of saliva so she could more easily glide her hooves all the way up to his tip and all the way down to his base in a much easier, and quicker motion. The pulsations beneath her hooves began to grow stronger and harder until suddenly a clear bead of something squeezed out of his tip. “Uh… what’s that?” she asked curiously, nodding down to it as she continued.

“Th-that…. well… that means I’m really likin’ what you’re doin’, sis.”

“Oh… well, good,” she said, her face growing red.

“If ya keep it up long enough, more’ll come out… a lot more.”

“How much? And that, uh, that means ya really really like it then?”

“A lot… and… a-and… eyup,” Big Mac moaned, his hoof once again stroking against her mane, this time more frantically and harshly. “You’re gettin’ real close to doin’ that for me. Try goin’ even faster.” Apple Bloom nodded her head, her face growing serious as she did as he asked. Big Mac’s head fell back against the wood behind it, his eyes falling shut before having a chance to see the rather silly sight of the straight face upon the young filly. Apple Bloom watched curiously as her brother’s entire body began to flinch and shudder with the occasional spasm of pleasure, and as his hips began to thrust his lower end ever so slightly away from the bed. His moans and gasps turned into helpless but loving grunts, and the small filly suddenly froze as his cock pulsated more fiercely than ever, and a thick, white stream erupted from its tip.

The hot, sticky liquid rained down upon Apple Bloom’s head and face. She quickly squinted as she felt some dripping down onto her eyelashes. The strange sensation inside her seemed to be brimming as she felt stream after stream of her brother’s steamy pleasure juices covering her face and slowly sliding down her fur. After feeling no more rain down upon her, she hesitantly opened her eyes. Before her, she saw her brother still breathing heavily, his eyes lightly shut, and a small amount of perspiration clinging to the fur of his forehead. Her mouth opened just slightly, and some of the strange substance slipped into her mouth. She smacked her lips at the odd, almost indescribable flavor and texture of the thick, still warm substance. It was somewhat salty and odd. In a way, it was off putting, but at the same time it was somewhat sweet and interesting. That, and it also affected the feeling inside her, as if when she swallowed it down, it made her feel even better.

After finishing up her taste test, she then wiped a hoof across her face and realized how covered she really was. The sticky white liquid now covered her hoof and began dripping down onto Big Mac’s crotch. “Wow, ah musta done really good or somethin’. That’s a lot of… whatever it is.”

“Ah haven’t cum that much in ah dunno how long, sis. That was amazin’.”

“…Come?” she asked curiously.

“….Uh… eyup…. that’s sorta a word for what it’s called when ya make me do that.”

“So… ah made you come… er… cum?”

“Eyup.”

Apple Bloom gave his brother a cheerful grin. “Ah sorta like how it tastes… and ah dunno why, but it made me feel really good inside, especially when you, um, cummed? Can ah make ya do it again? And is there anyway ah can make even more come out, make it feel even better for ya?”

“Ah… uh, welp… ah guess ah could let ya try again. This time ya can use your mouth.”

“My mouth?” the filly asked, her eyes growing wide, and one of her eyebrows raising. “That seems a bit weird don’t’cha think?”

“Nope, it’s pretty normal.”

“Oh… then what should ah do?”

“Don’t you fret,” Big Mac said with a soft smile, looking down into his worried sister’s eyes. “Ah’ll guide ya through it, and besides, ah’m sure you’ll do just as good as ya did this time.”

“O-okay… so what’s first?” she asked with a gulp.

“How about ya start by lickin’ it. Needs to be cleaned up anyways.”

The filly’s heart fluttered with excitement at the thought of licking the substance off of his stallionhood, but she froze for a moment, realizing how small it had shrunk, back to the size she had grown used to seeing it so many times before. “Why’s it so little again?”

“That happens after ah cum. Don’t fret. Ah’m sure you can get it hard again real easy with that tongue of yours.” Apple Bloom beamed with confidence before thrusting her tongue out of mouth and leaning down to his crotch. The smell upon his stallionhood was salty just like the taste of what came out of it, along with what she figured was something close to sweaty or musky. She could not quite put her hoof on it. Whatever it was, it was already making her salivate, even if it was such an odd smell, her tongue was dripping. She leaned down and drug her tongue slowly up her brother’s shaft, picking up any of the semen that had dribbled down it after his orgasm. She smiled happily as the strange taste filled her mouth and at the wonderful feeling it brought with it.

She placed her front hooves upon his inner thighs, giving herself better leverage as she began to lick more deeply. Crossing her eyes just slightly, she watched eagerly as his cock began to pulse back to life. It moved beneath her tongue and she watched with amazement as it slowly began to grow larger and larger. She began having to lean her entire body forward so that she could lick up his entire length. Big Mac’s moans began to return and his lower half moved softly with the rhythm of his sister’s licks. His cock was slowly being coated in Apple Bloom’s warm, sticky saliva, making the gliding of her taste buds against his skin incredibly smooth and quick. Although she could tell that he was enjoying her tongue play, she also felt as though it was not enough. She soon remembered that he mentioned her using her mouth as well. She pulled away, spit dripping down her lip and clinging to the fur of her chin. “Ya wanted me to use my mouth too, right?” she asked sweetly.

Big Mac blinked his eyes open softly and then smiled at the idea, nearly forgetting with all the pleasure he was receiving. “Eyup.”

“What should ah do?”

“Um…” He blinked again as he attempted to process how to put such an action into words. “First ya gotta hold up my stallionhood… straight up… and then ya put your mouth over and move it in and out.”

“Uh… okay… ah think ah get it. Ah’ll try,” she muttered lifting his stallionhood up at the tip, the middle, and finally discovering that the best way to go about holding it in position was from the base. She then leaned down and pressed her pursed lips against his tip, giggling softly as she gave it a kiss. She opened her mouth as wide as she could, pushing down to fit the wide tip inside of her cheeks. She paused for a moment, her mouth completely full and even stretched. He had told her to move her mouth up and down, but it was already filled. She attempted to do as he asked, and quickly bobbed her head, not moving up and down but an inch. She closed her eyes and tried to push it in further, not wanting to disappoint. Her eyes quickly shot open as his tip pushed against the back of her throat. She struggled to hold back her reflex to close her mouth. She did not want to bite down and hurt him. She pulled away quickly and began to cough, spit once again spilling from her mouth. “…. Don’t think I’m doin’ it right,” she said weakly after finishing up with her fit of coughing.

“Here, get up would ya? Ah’ll take over so you can see how it’s done. Big Mac rolled over onto his stomach and then stood up on all four hooves, towering over the small filly. She looked up at him questioningly, but was quickly answered. “Crawl underneath me so mah stallionhood’s hanging right over your mouth.” She nodded and obeyed her brother’s words, sliding beneath him and looking up directly at his thick, rock hard cock, its tip dangling just out of reach. “Now put your mouth around it again.” She pushed her back away from the bed and craned her neck so that her mouth could reach him. She then pushed forward, letting his tip pop into her mouth again. “Ah’m gonna start movin’ it. Don’t be afraid when it starts pushin’ back. Ya just gotta relax and loosen up your mouth and throat. Ah promise ya it won’t hurt then.”

Apple Bloom’s eyes grew wide as she swallowed down the saliva that had gathered around his member. Her heart began to pound with both fear and excitement as he slowly pushed his hips forwards, causing his thick shaft to slide past her cheeks and near her throat yet again. She squinted her eyes shut, as she felt it pushing against her uvula and did her best not to succumb to her reflexes. She trusted her brother and of course did not want to let him down. Big Mac moaned, feeling her throat tightening against his tip as it tried to repel it. “You’re doin’ good, just remember what ah told ya and everythin’ll be fine.” Her stomach heaved and her heart pounded even faster as his cock slid deeper and deeper into her throat, pushing at its edges before curving to fit the passage. “Now ah’m gonna start movin’ in and out.” His sister tried to hold back wet gags as his stallionhood slid in and out of her throat. She was just glad that he did not put its whole length inside her. She was absolutely sure she could not handle it. Instead, she used the rest of it for leverage, gripping her hooves tightly around the lower half of his cock, using it as a way to hold herself up as he continued.

Finally she began to relax, getting used to the sensation of his hard rod sliding, pushing, and rubbing against the insides of her throat. Instead of feeling pain or panic, she felt the strange feeling from deep within yet again. As his movements began to grow faster and harder, the feeling grew more powerful and pleasurable. She let herself go weak besides her hooves which still grasped around his base, and listened to the sloppy wet sounds his cock made inside her throat. The idea of him taking over, just using her as she lay there weakly, made the pleasure inside her grow even stronger. She felt as if she was running out of air, even if she could still breathe from her nostrils. She was not afraid though. Instead, she was anxious for him to continue, to make him cum yet again and be the good sister that she was.

His movements began to grow faster and held much more strength behind them, but they were also growing more sporadic, and Apple Bloom could feel his entire body beginning to shiver with pleasure. Remembering what happened when she used her hooves, she could tell he was getting close to releasing his wonderful juices yet again. Her cheeks tightened around her brother’s thick shaft, as if instinctually, and she began to suck. Big Mac moaned loudly, encouraging her to continue the milking. As her cheeks squeezed and pulled against his thick shaft, she tasted his pre upon her tongue. It was stickier and sweeter than his ejaculation, and she knew it was just a hint of what was to come. As he began to thrust even faster, she squeezed his cock more harshly between her cheeks.

“Mmmeeeyup… Apple Bloom… y-you’re makin’ me cum,” Big Mac sputtered out as his eyes rolled into the back of his head. His sister’s eyes instead shot open as one final, powerful thrust shoved his cock deeper inside her throat than it ever had been before. Her eyes then copied his, rolling backwards as his hot, thick seed exploded into her throat and poured down into her stomach. It not only warmed her insides like a hot glass of milk before bedtime, but also stirred the feeling inside her even further. Her stomach got fuller and fuller as his semen continued to shoot out of his tip, the thick ropes easily sliding down her throat. Her stomach stirred, almost sickeningly, the sensation not that of pleasure any longer.

The filly quickly pulled away from her brother’s cock with a sloppy pop, even though he had not finished. His cock pulled up against his stomach as white continued to explode out of it, covering Apple Bloom’s small body. She smiled blissfully as the warm fluid clung to her fur and soaked down into her skin. It was warm like a shower, but the sticky substance was even better. With a final grunt, Big Mac finished, the last of his seed dripping down onto his sister.

“Wow… th-that’s a lot…” she muttered weakly, opening her eyes and examining the damage. Her pale yellow fur was nearly completely white with the amount of cum covering it. But in amongst all of it, down near her crotch, was something else, something clear and glistening. She could feel it warm and wet against her marehood, and could feel it seeping out from between her slit. “B…Big Mac?” she muttered, an almost fearful look upon her confused face. “What’s happening?”

Big Macintosh chuckled guiltily at her innocence as he peered down to examine what had frightened her. His face then flushed as he shook his head gently to and fro. “Welp, ya know how stuff comes out of me when ah’m enjoying what’s goin’ on? Fillies can do the same. It’s just yer version of it.”

“Oh… so… ah… ah’m cummin’ too?”

“Heheh, nope,” Mac said with a smile. “You’re just gettin’ excited. “Ya can cum… sorta. Just have to get enough pleasure like ya did for me….” his smile widened into a mischievous grin as he pondered the situation. “… Ya do know what marehoods are for don’tcha? Why yer parts are different from colts?”

“For peein’ and foals… duh… and cause ah’m a filly and not a colt.”

“Enope… you’re right… but there’s more to it. We can share pleasure.”

“But weren’t we already? Ah was enjoyin’ it too.”

“Not as much as me.”

“No… but… okay, how?”

“Stallionhoods are supposed to go inside of marehoods. That’s how it works.”

“Oh! … But… ouch… how the hay is somethin’ as huge as your stallionhood gonna fit inside that tiny little thing? Or does it stay small or somethin’?”

“Nope… but your marehood’s plenty bigger than ya think. It can stretch.”

“Ah… ah dunno. Sounds like it’d hurt.”

“Don’tcha wanna feel good too?”

“Ah do but, ya know… do you wanna put your stallionhood inside me?”

“Eyup.”

“I-if ya say so Mac… ah just…”

“It’ll be fine. It’ll hurt a little at first, but it’ll feel good after that. Ah’ll even let you take the lead. You can stop or slow down when it hurts.”

“Okay, that sounds a little better. So how do we?” Big Mac rolled over onto back and patted his crotch.

“Ya gotta sit down on top of it, but first how about we get ya a little more used to it. C’mon, Just take a seat.” Apple Bloom hesitantly crawled into his lap and lowered herself down onto his crotch. She let out a soft moan as the surface of his shaft pressed against her tight slit, spreading it just slightly and letting the juices that had gathered inside it flow out. She blushed deeply and shuddered.

“That… felt really good.” Big Mac smiled and wrapped his front hooves around her tiny waste as he began to thrust his hips. The smooth skin of his shaft moved up and down her slit, causing her to moan more loudly and go weak in his grasp. “Mmmac… ah...” she muttered, drool spilling from the edges of her lips.

“Eeyup, told ya it feels good, and look how wet you’re gettin’, sis.” He nodded down to her crotch, where more of her own liquids were seeping out and covering his crotch.

“And it’s gonna feel even better when it’s actually in there? Is… is it ready for that?”

“Hmm… should be wet enough. Give it a try,” he said with a nod. Apple Bloom lifted her flank as her brother positioned his cock with his hooves. She had to stand up upon her hind hooves so that her marehood could reach his tip.

“O-okay, so ah just slip it in and go?”

“Nope,” Big Mac said softly. “Ya gotta go slow… else it’ll hurt. Just ease it in there.” Apple Bloom nodded as she gently lowered herself down, his thick tip pushing at her lips. She groaned loudly as her lips widened and stretched to accommodate the massive object. She grunted and groaned but realized that she was getting nowhere. She began to push more harshly, but still, his stallionhood would not enter. Instead it just caused her pain and frustration. The stubborn filly huffed and pushed even harder. Her eyes widened as it suddenly pushed inside her with a harsh pop, sending a rush of both relief and pleasure through her body. The biggest part was inside her, and sliding it in deeper seemed to be a bit easier going, although her insides seemed not to want to cooperate. They tightened around it and attempted to hold it in place rather than open up and allow entrance. She let out a deep sigh, attempting to relax herself as she had with her mouth. She bit down on her lip and groaned softly as she slowly slid more and more of the thick stallionhood inside her, feeling it slowly and almost painfully push at, stretch, and move her insides. It was incredibly uncomfortable, but she remembered what her brother had told her. It would start feeling good. She just had to get used to it, and let it stretch her out, loosen her up, then she would feel pleasure again. She gritted her teeth and pushed it in more quickly, wanting to get the painful part over a bit faster, but not so much that it hurt. She could feel it pushing deeper and deeper inside her as if in an attempt to reach what she had been feeling inside her all night. She yelped, shuddered, and then gulped, swallowing her pain. She tried to push it in further but only felt pain. She had reached her limit.

“Ya don’t have to go any further, sis. You’re doin’ great,” her brother assured her. “Now just start movin’ it in and out, like we did with your mouth.” Apple Bloom grimaced, readying herself for more pain as she began her movements. The muscles in her face and body began to loosen as she realized that there was no pain any longer. It did not quite feel good, but it was no longer uncomfortable. She continued her movements. Her insides were still nice and snug around his thick shaft, but she could feel them give way much more easily as it pushed inside her.

As she continued to move his stallionhood in and out of her tight, young, inexperienced marehood, the uncomfortable sensation it gave her slowly grew more and more pleasurable. She soon figured out exactly where her limit was. Just a slight push past the ring at the center of his cock was where it began to hurt. So her cue to move back up was when the ring slipped inside her. She began to realize that the ring was her most favorite part. Although the young, innocent filly did not know of the incredible sensitiveness of her clitoris, she could certainly feel it. The ring not only stretched her lips wide with its passing, but also rubbed and pushed against her swollen, wanting clit.

Apple Bloom changed her movements from long, deep thrusts to quick, short ones so that his ring would go in and out of her nearly every second. She moaned and gasped aloud with her brother, and was both warmed and excited by the fact that they were experiencing such wonderful pleasure together. More and more of her juices flowed out of her and onto her brother’s cock as the sensation within her grew stronger yet, allowing her movements to become even faster and more fluid. She was amazed, thinking the sensation had reached its peak, yet it continued to climb. Suddenly, her entire body began to shiver and shudder as the strange, but amazing sensation pulsed through her very being.

“M-mac…. ah… ah…” she muttered helplessly, stopping everything that she was doing as his ring pushed past her clit once more. “Ah… think ah’m cummin’!” She then gasped and Big Mac groaned as her insides tightened fiercely around his cock and then contracted as a small squirt expelled from her marehood and an intense orgasm rocked her body and mind. She moaned loudly and gurgled as she grasped needlessly at his stomach. The filly then finished with a weak sigh and collapsed upon her brother, his cock still inside her.

“Sis, ah’m gonna cum too.” Apple Bloom’s heart pounded at the statement as her excitement and energy returned. She was ready to be showered in the delicious substance again.

“Can ya put it all over me again?” she asked sweetly, giving her brother a loving gaze.

“Course ah can. If that’s what ya want,” he responded with a nod. Apple Bloom pulled her sensitive marehood away from his cock with another shudder and quickly grabbed it in her hooves. She stroked quickly and vigorously, her mouth wide and awaiting his orgasm. It only took a few seconds for Big Mac to reach his peak, and with a loud, loving groan, his thick cum once again exploded out of his cock. Apple Bloom’s eyes quickly squinted shut as the salty, oddly textured substance splattered into her mouth and upon her face. She quickly gulped it down as her body grew warm and her fur grew wet with stream after stream of her brother’s juice. Big Mac huffed heavily as he finished, knowing his sister had emptied him completely this time. He then smiled as Apple Bloom grinned up at him. Ropes of his cum lay stringed across her pale yellow fur and upon her red mane, and traces of his previous orgasms left her fur clumped and matted. He then looked down at her marehood, its pink insides still swollen and exposed from stimulation, and its wetness glistening in the lamplight.

“Ah’m glad ya convinced me to let ya help,” Big Mac muttered, his heart pounding. The lewdness of the nearly forbidden act was once again weighing on his guilt, but at the same time, that fact made the situation seem even better.

“Me too,” Apple Bloom sighed, rubbing her hooves gently against her brother’s stomach. “And thanks for returnin’ the favor. This has to be the best night of siblin’ bonding ah’ve ever had. Ah don’t think ah’ve ever had so much fun with ya, Mac.”

“Heh, me neither, sis,” her brother replied, chuckling softly.

“We’re gonna do this again, right?”

“Ah… um… eyup… but don’t tell nopony about it, okay?”

Apple Bloom understood that this release of pleasure was something to be hidden even if she did not know the reasoning behind it, or the fact that something of the sorts was considered wrong and immoral between those of the same kin. Along with that, there was no way she was ruining such bonding with her brother by letting a secret slip. She smiled and nodded her head. “Uhuh, of course. Ah won’t tell nopony, not even AJ or my friends or Granny Smith, nopony.”

“Good, then we gotta deal. Now, ah know it’s late, but ya need to take a bath. Can’t let anypony know what we’ve been up to and it’s pretty obvious lookin’ at ya.”

“Eyup,” she said with a giggle, mimicking her brother as she struggled to hop off of the bed, her legs still weak and shaking from the experience. “Night, Mac. Ah’ll see ya in the mornin’,” she cooed once she finally managed to get down. “Love you.”

“Night, AB. Love you too,” Big Mac muttered in embarrassment. With that, Apple Bloom snuck down the hall and into the bathroom, the loud snores of Granny Smith still billowing out of her room and flowing through the hallway. Apple Bloom smirked. It was easy to keep something hidden from Granny Smith, but it would be much more difficult with Applejack around.
