Big Macintosh shifted in his bed, having just woken from a rather intimate dream between his marefriend Cheerilee and himself, his sweat-soaked sheet tangled around him and between his stifles feeling especially 'heavy' as it always did after such a dream. Mac shifted rapidly, trying to squirm free of his sheet cocoon and succeeded moments later, the sheet quickly kicked across the room in his frustrations and slamming against a wall then falling to the floor.
Mac knew his marefriend wouldn't be getting back for another few weeks from her trip, also knowing that that was too long. He needed to take care of this problem before it got too out-of-hoof, especially with Applejack going into heat earlier today, her pheromones having set him on edge and the whole house smelling like a fertile mare - torture for any stallion that couldn't breed said mare but still caught in its radius. Mac could feel himself pulsing in need between his mattress and himself as he smelled Applejack in the next room, the scent of his fertile sister making his base urges go wild. He needed relief.
Deciding that his 'need' wouldn't decrease by itself with a mare-in-heat nearby, and that merely his own hoof wouldn't be able to get him off this time, given just how hard he'd tried to bring himself to orgasm the previous night, Mac decided to enact something he'd been wanting to try for a while but never really had the nerve to before, always afraid of getting caught. His body long in need of release and his naturally adventurous libido making his mind up for him, however, Mac decided now was the time.
He got up and went to his door, peeking out and making sure nopony was up. Upon seeing the rest of the house was dim, Mac quietly made his way downstairs and after gathering a few things went out the front door, heading to the location he was once hesitant to visit. Not tonight he wasn't hesitant. Not when he was THIS horny.
Mac arrived at his destination a few minutes later, an old dairy barn they had stopped using once the boarding and work contract with the cows that had lived there ended, with them having come to a disagreement with the cows working for them and yet to renew the contract on new terms. Mac went behind the barn and flipped the main fuse box before heading inside, tugging the pull-chain with his mouth. When he did, a single light above the barn's entrance, as well several within the main building and one inside each stall, came to life. Mac winced at the comparatively bright light, his eyes adjusted for the dark night - but when they adjusted, Mac quickly saw that the barn was empty just as expected.
Mac quickly went to one of the stalls, his semi-hard stallionhood swinging beneath him as he looked inside and saw his goal: a top-of-the-line milking machine, a shiny steel contraption designed to relieve a cow's udders of their milk. Mac only looked at the machine for a moment, then flicked the switch labeled 'Standby Power' on the machine, hearing it whirring to life and making a soft electrical buzzing as the lights and buttons on the control panel lit up.
Each of the pumps was controlled by a separate power switch and needed to be activated by flicking a switch on the main unit, and beneath that an optional timer for the duration of the milking session, and underneath that a couple other switches for some additional, for-now less important features.
He quickly took notice that this machine had larger cups than the standard models, remembering why he'd entered this stall in particular: the extra-large teat-cups for a particularly-endowed cow that had lived with them. Rosie was a large cow who had required bigger cups than the others who'd boarded with them, but the expense of the custom parts was easily absorbed by the profit they made from her more-than-average milk production. A happy boarder and employee, and money in the bank, Win-win.
Big Mac picked up and studied one of the milking cylinders, turning it over in his hooves. The inner shaft was nearly two and a half inches in diameter and just over ten inches deep - and hopefully big enough to fit his rather swollen and above-average stallionhood. As he felt his lust welling again, he resolved to satisfy what he'd been wanting to do since he'd first bought the machine, doing a quick test by setting his member beside the cup. It looked like he'd just fit in length-wise, and likely width-wise as well. Lucky him; it looked like he would fit, if only just.
After adequately lubing himself up with some teat-lubricant he'd brought from the house, Mac lay on his side and aligned his erection with the milker, slowly pushing all the way inside to make sure it was wide enough for him. With the machine firmly hugging his shaft within it, it was a bit tight all the way in there as expected, but deep enough to contain him all the way. He knew he'd need the extra room when he flared, but...
The inner lining of the cup was soft and squeezed against his entire hardening shaft moments later, the sensation of it gripping his whole length making him jerk his hips up slightly on instinct as it met his base. It felt vaguely like a mare's vagina but lacked the body heat and the internal ridges that a real mare had, indeed rather cold and smooth inside. Slightly disappointed, Mac flicked one of the switches marked 'Heating', and moments later felt as the cold rubber of the cylinder surrounding his member grew warmer, eventually ending up at a very comfortable, just-above-flesh temperature some seconds later. At the sensation of a warm, soft, and lubed hole encasing him and the pheromones from his sister's estrus still pumping through him, Mac started to softly undulate his hips in anticipation, testing it out. He was indeed finding he was feeling pleased by the sensations he was getting; finding it not near as good as the real thing, but it would have to do. Better than his hooves by miles, considering it was soft and fully encapsulated his member.
Mac couldn't help but moan lightly as he humped softly into the tube, holding it at an angle so it would feel like a mare was on top of him and riding him if he closed his eyes and imagined it. Knowing that this was nothing compared to what he thought he'd feel, Mac looked at the pump controls for a solution, quickly finding three knobs labeled from 'Low' to 'High' as well as a row of three switches right below for vibration controls labeled the same. Mac considered which to choose, the cup having slid off of him as he'd stood.
As he reached his hoof to flip the 'Low' labeled switch for vibration and turned the dial for suction to the second notch, Mac head a shuffling behind him right after they clicked on and the machine whirred to life. He instantly tensed, turning his head behind him to find the noise's source. As he looked back his eyes dilated, his whole body tensing as he saw he had a visitor, only the silhouette of a mare wearing a Stetson visible against the bright light behind her.
~ ~ ~
Having heard Mac get up in the middle of the night and curious where he was going at this hour, Applejack had gotten up and followed her brother outside, curious as to why the hay he'd be coming out here at such an hour. She followed at a long distance and stayed silent, hoping he wouldn't hear her or smell her heated scent and detect her, unsure what she'd say if he did. When he'd reached the old dairy barn and flicked the lights on, Applejack had hidden behind a hay-pile, not wanting to be seen in the now-lit area. She peeked around it and watched as Mac headed inside, only then moving up to the barn's opened main doors.
As she heard the quiet electrical buzzing coming from Rosie's old stall that told her the milking machine was starting up, Applejack found herself perplexed. Why in the hay would Mac be using a milking machine this late at night, and with no cows to milk? Her curiosity piqued, Applejack snuck up to the stall, careful to avoid making much noise. A few moments later, Applejack subtly looked in the stall - and what she saw made her eyes widen.
Applejack saw her brother lay in a corner of Rosie's old stall, watching as he put the milking cup over his stallionhood and started lightly humping up into it. Applejack couldn't help but feel her marehood burn more intensely as she watched her brother masturbating with a machine, then watched as the cup slid off and revealed all ten inches of his lightly-glistening pink-and-black stallionhood, slick with what she assumed was udder lubricant. Applejack stepped out into the open as she saw her brother fiddling with the control panel to get a better view of her brother's girthy cock, unintentionally leaving herself exposed as she watched on in surprise as well as lust - before Mac turned to look at her.
Neither said a word for what felt like forever, neither sure just what they were supposed to say, their eyes simply locked to each other's, blushes burning hot on their faces. Applejack could hear a light dripping behind her as she looked on at the rather arousing scene, her heated marehood letting its interest be known as her clit winked near-constantly behind her, the heat in her belly growing hotter as she sensed a virile stallion with a rock-hard breeding tool nearby. Finally, Applejack stepped forward, watching as Mac flinched back.
"Um...h-hi Applejack..." Applejack heard Mac squeak out, his quiet near-whisper barely audible over the buzzing of the machine, a light suction also heard from the milking cup now lightly vibrating on the ground. Applejack looked down to the source of the noise, seeing the cup lightly fidgeting against the ground, her mind once again imagining it on her brother's member.
"Ah wanna watch." Applejack suddenly stated with a lustful tone, taking another step towards her stunned brother.
"Ex...excuse me?" Big Mac asked, his heart dropping to his hooves. Did he just hear what he thought he'd heard?
"Ah said, Ah wanna watch." Applejack said again, a blush growing hot on her face, "Ah wanna see you get...milked."
Applejack had always found her brother attractive, and had, on a few occasions, barely restrained herself in the peaks of her heat from going to her brother and presenting herself to him, to be ravaged by him, with only the thought of them having a foal resulting from it ever preventing her from actually doing so. Tonight had been one such night, in which she'd rubbed herself to the secret thoughts of Big Mac mounting her, his ten-inch member sinking deep within her and quelling her heat.
Another awkward silence reigned with Big Mac staring in disbelief at his sister while she looked between the milking machine and his lightly-glistening cock, the cup on the floor still lightly buzzing with a vibrating hum, considering what his sister had said. Big Mac had always loved Applejack but hadn't really considered her in a sexual way in a long time past his involuntary thoughts during her heat, when he'd used his hooves to relieve some stress. Now, however, as she stood before him smelling like the mare in need she was, this set his mind ablaze with lust for her.
Mac couldn't help but see his sister in a new light, letting his eyes wander over Applejack's bare body; he looked over her gamboge-orange coat, seeing the faintly bulging musculature underneath that he had seen so many times before, earned from her many years of hard work on their farm. He then felt his eyes drawn down her slim barrel to her toned, apple-marked rear, seeing the curves so perfectly arranged – her hips and ass wide but not too wide, not too flat, utterly perfect. The perfect broodmare with perfect foal-bearing hips, just ripe for breeding.
Applejack almost considered saying 'forget it' and heading back to her room, seeing Mac unmoving and apparently deep in thought, considering the worst of it. After this encounter, she knew she'd have to get herself off again, thinking that maybe a few more orgasms to her dildo while thinking of him would finally exhaust her enough to finally fall aslee—
"Eeyup." Applejack heard, jumping slightly from the sudden voice before looking to the source. Looking to her brother.
Had she just heard him right? Had Big Mac just agreed? "Ahm sorry...wut?" Applejack asked, rubbing her ear with a forehoof and pretending she hadn't heard him.
"Ah said 'eeyup'." Big Mac said again in his deep bass voice, this time nodding to his sister as she looked to him. "Y'...y' can watch."
It was Applejack's turn to be stunned this time. She'd have never thought he'd say yes! When her temporary paralysis wore off a few moments later, she took a step towards her brother, then watched him go back to the corner he originally sat in, the milking cup still dancing around on the floor. She sat within a couple of feet of her brother, watching as he grabbed the cup between his hooves – then held it out to her. "Y' wanna put it on me?"
Applejack looked at the cup, then to her brother, then to his thickly-erect cock. She was tempted to smack herself to make sure she wasn't dreaming, but instead she simply reached over and took the cup in both hooves, then looking down to her brother's rock-hard member, the soft bobs it was giving undoubtedly encouraged by her being in heat and her gaze upon his hardness. She then found herself having second thoughts as she felt the very-real sensation of the vibrations rolling through her hooves, but as the scent of a stallion's musk setting her lustful mind up another notch, her body wanted her to sink him into herself instead of the cup, not leave! Then she thought of an alternative to him simply sitting on the floor...
"Hey Mac, how would ya like t'...mount me after Ah put this on ya?" Applejack asked, lightly playing with what she held in her hooves and looking over to her brother; "It'd feel a lot like yer matin' me fer you, but without a foal." she explained, thinking to herself just how she would get herself off in that event. She mentally shrugged, however, more concerned about her brother's pleasure than her own for the time being despite the burning between her legs and in her belly. She'd put him into his rut, and she was gonna help him out of it.
Suddenly, Big Mac felt a moderately-strong sucking sensation on his cock as Applejack slid the cup swiftly down on him, his ultra-sensitive flare pulled in first, before the suction helping to pull his well-lubed stallionhood deeper still. The sudden rush of sensations as his medial ring slid in, the second most sensitive part of his stallionhood starting to be stimulated now, made Mac's hips jerk up against the cup now, feeling the soft, warm inner walls of the machine starting to somewhat tightly squeeze and loosen against his stallionhood from base to tip every second; the same motions that would milk a cow's udders, and Mac finding it felt not unlike a mare's vaginal muscles as she was nearing her climax.
Mac soon got to his hooves as he watched Applejack approach him, his mind ablaze with pleasure now as he felt the sucking, squeezing sensation on his rock-hard phallus; watching as his sister turned around, presenting her hindquarters to him.
"Ahm gonna milk ya good, big brother..."
Mac watched as Applejack then lifted her tail to him, her soaked, virgin marehood and pert, untouched plothole revealed in full to her brother as her tail curled over her back, inviting him to mount her. The increased scent of her need as she raised her tail made Mac get to his hooves in an instant, the constant winking from her vulva only stimulating him that much more.
He needed to mount his mare.
Mac felt his loins on fire as he climbed over his sister and gripping her sides tightly as he mounted her, positioning the cup right between her legs and just under her slit, right between her teats and against her burning lower belly. Mac heard Applejack moan slightly as she felt the weight and grinding of a stallion's underbelly on her croup, the vibrations of the cup on her sensitive teats and within her belly as well, and finally the tight grip of his hooves on her barrel.
Applejack gripped the cup between her legs and tried to grind her marehood against his pelvis and the cup, though that didn't accomplish too much for her own pleasure, merely stoking the flames more instead at the teasing. Big Mac, however, moaned loudly as he started he to thrust harder; the thought of her wet, fertile marehood near his cock at all just adding to the warm, vibrating, slick and suckling sensation on his cock as he slid out of the milking extension, only to be sucked right back into the hilt.
Big Mac kept thrusting beneath his sister, his eyes sealed shut in his pleasure; it feeling like, for all intents and purposes, that he was rutting his fertile sister. He felt his member pulsing within the milker, his heavy, seed-ladened balls slapping against his sister's inner legs with each sharp thrust, getting a quiet moan from her in response each time they did. He buried his muzzle into her crest, smelling the scent of a hard day's work mixed with a heated mare's pheromones, both highlighting her own natural scent; the scent of his sister.
He kept his rough humps up for a while, keeping his grip on her tight, instinctively not wanting this fertile mare to get away until he'd climaxed within her and gave her his foal, his body not knowing he was lodged inside of a machine instead of the mare. Nonetheless, he moaned out near-contently in pleasure, his humps steadily growing more rapid and saccadic, as well as his throbs and rolling waves of pleasure.
Finally, a few minutes after he'd started thrusting, Mac was getting frustrated at not having reached his climax yet. Sometimes Earth-pony stamina was a curse, it would seem. He soon reached over to the machine and moved the knob up to medium, feeling the suckling on him growing stronger, then flicked the switch for medium vibration as well.
Both moaned as he flicked that switch, Applejack now getting more turned by the stronger vibration within her heat-filled belly, feeling the pace of his balls smacking into her legs was increasing as well as the vibrations affecting her vagina and clit from the outside; not to mention her sensitive teats more, with each rock of his hips already rubbing the vibrating cup in-between those small mounds. Mac meanwhile increased the undulations of his hips, feeling more intense pleasure now as he'd increased the stimulation, feeling the insides of the machine softly rolling over him a bit more rapidly.
Finally, a couple of minutes later, Mac finally felt his glans starting to flare up and his throbs grow more insistent, the machine growing tighter around his head, with him knowing well what that all meant. He flicked 'High'-labeled third suction switch and turned the vibration knob to max. Big Mac moaned very deeply as that huge spike in sensations finally set him over, humping as hard as he could now, his thrusts unsteady as he tried to bury himself on instinct as deeply into the 'fertile mare' as possible, feeling his balls hugging tightly up to his body and ready to spend their very virile load.
"Mmm, y' getting close bro? Ya gonna cum in me? Gonna get yer sister pregnant?"
Upon hearing those words from his own sister, Big Mac felt himself swelling huge within the machine as he moaned out again, more ferally. He could only think of and smell the procreant mare beneath him and the suckling on his cock as his body prepared to impregnate her, amazed his fully-flared head actually fit in the machine, with Applejack feeling his grip on her sides growing strong enough to nearly impede her breathing. She heard a muffled, victorious breeding whinny escape from his throat as he finally reached his climax and slammed his hips against hers, his stifles encasing hers and holding her there with her crest firmly held in his teeth as he pulsed even harder in the machine.
Seeing what her previous heated words were doing to her brother, Applejack continued."Yeah, cum in me bro! Gimme yer foal!"
"EEEEEEEEEYUP!"
Applejack felt as Mac tensed up, then watched the tubes connecting him to the machine go from clear to off-white, though it was very obvious that it wasn't milk being siphoned from her brother. She watched as his seed traveled through the tube to the machine and started to pour into the first of four containers on the machine and filled it half way, amazed at just how much her brother was producing. How much he was cumming because of her.
"W...wow big bro."
Big Mac continued to violently thrust and grit his teeth as he felt some of the most intense, extended pleasure he'd ever had, the constant milking and sucking and vibrating on his penis making his orgasm far surpass anything he'd ever felt before in intensity and duration; he was panting hard with his eyes sealed shut, his mind awash in bliss. He held on to Applejack for dear life, her body his only anchor in the whirlpool of pure, intense pleasure he was awash in, shivering lightly on her back as he was drained of more of his essence.
Mac tried to speak, to even breathe, but each harsh suck on him, each pulse of his seed that was stolen away from him, only made him breathless once more; only able to continue to experience his most powerful, prolonged orgasm to date.
~
Finally, nearly a minute later, Mac's humps had grown weaker, as did his spurts. After a minute and a half, he was finally, thoroughly drained of his first load, the machine having taken all of his foal-cream he'd given it and left him without a drop left. He finally recovered enough motor function and mustered the control over his hooves required to reach over and disable the machine – only for Applejack to knock his hoof out of the way when he tried.
"C'mon bro, Ah know y' got more than that in ya. Y' only filled up...what...not even half?" Applejack teased, with Mac noticing that, in fact, only half of one of the quart collection canisters attached to the machine were white with his contributions. Mac felt the harsh suckling on his now-sensitive cock and whimpered at the discomfort, with Applejack finally sighing and letting his hoof lower to the machine – before suddenly nudging it again and making it flip another switch.
Big Mac felt as a wave of electricity surged through his penis, making him grip Applejack's sides tighter again; the intense, unexpected sensation rolling through his whole member. It was apparent Applejack had made him activate the electro-stimulation portion of the machine, which helped the cows to completely empty their teats if they were having trouble getting all their milk out, with that saving them having to take a second trip back to the machine only hours later. The currents weren't harsh enough to cause major discomfort or any harm, but were enough to cause the muscles it was affecting to contract involuntarily.
"Mac, we need t' drain y' all th' way , er yer only gonna be out here again in a couple hours!" Applejack said in a comforting tone, the same thing she'd always said when a cow initially refused to stay on the milker until they were totally finished. Mac only moaned, before giving a stiff nod. He knew she was right, and that he wasn't done yet. He was never done with only his first orgasm and didn't know of any Earth Ponies who were.
Mac was completely silent save for one quiet whine as he felt another gentle surge of electric roll through his cock, making it flex involuntarily in time to the electrical pulses, and instantly regaining any hardness his first orgasm had made him lose. His humps started again after he fully regained his hardness, but Applejack had other ideas. She was beyond horny now herself, and the cup's vibrating against her belly and teats was only making the burning in her even worse.
"'Ey Mac, get offa me. Ah need somethin' too y'know..." Applejack said as calmly as she could, her heat at an all-time high, her need to be bred now growing very powerful; thoughts of pulling the milking cup off of him and him planting his ready cock hilted in her, of him rutting her until he came deep within her body and sired her a foal. Thoughts she barely overcame acting upon.
Mac hesitantly dismounted her, though his back continued to arch and his hips to hump forth rhythmically every two seconds with each jolt of electric surging through his whole crotch. Knowing what Applejack needed, and this not being his first time being sexual around a heated mare he loved, Mac quickly buried his muzzle into her soaked crotch after he climbed off and found it literally inches from his muzzle, pressing tightly into her marehood and licking deep, enjoying the flavor and scent of his sister.
Applejack gasped at his sudden aggressive lapping but was absolutely in no way displeased by it. In fact, she gave Mac a loud moan as he continued ravaging her entrance with his tongue, pushing back against him and easily able to tell he'd done this with Cheerilee at least a few times previous by all the right spots he was hitting inside of her!
"Oh by Celestia Mac, 'at tongue! Somepony was eager t' taste mah 'Apple pie'..." Applejack moaned out, her head tilted back as her hips started grinding against Mac's muzzle, her pussy winking near-constantly against it and only stimulating the still-horny stallion all that much more, her desires finally being tended to at last. Each jerk of Mac's hips every two seconds made him press deeper into Applejack's marehood for a moment, Applejack responding with another clench on his tongue and wink each time.
"Mmmmm-hm!" Mac wordlessly commented, letting Applejack know he rather liked the flavor of her thick juices; a flavor fairly sweet, slightly bitter, and with the faintest hint of a Jonagold apple, all superseded by the universal flavor of 'heated mare'. The vibrations that that phrase sent through Applejack's marehood made her tense for a moment, before letting out a ragged breath.
They kept on like this, Big Mac eating Applejack out as he himself was over-stimulated, the machine suckling and kneading his once-drained stallionhood and not relenting one bit. Finally, a couple of minutes after his first orgasm, Big Mac felt the familiar pressure in his pelvis forming again, his humps growing more rapid and demanding.
Determined to bring his needing sister with him into orgasmic bliss, with him able to tell she was getting close herself by her increasing, rhythmic squeezes on his tongue and now-constant winks, Mac did what he'd always done with Cheerilee when she was near; he pulled out of her marehood and started to rapidly lick at Applejack's clit's hood, and when she winked the next time he caught her hood on his upper lip, leaving the little heart-shaped nub defenseless to the quick licks he planted all over it with just the tip of his tongue.
Finally, he himself tipped over the point of no return, his threshold overstepped, the scent and flavor of his fertile sister, the pulling sensation of her inner muscles squeezing on his lower muzzle and the same from the machine on his cock, quickly bringing his climax. With one last involuntary contraction from a final shock, he started to rapidly hump again, his cockhead flaring up again in the machine and ensuring his second load could only go directly into the collection tube.
With a deep moan from Mac, that vibration directly onto her clit only adding to Applejack's stimulation and making her tense up more, Mac's hips jerked forward sharply one last time, his balls tightening up to his body and tail flagging before he once more released his flood.
Applejack watched as the tubes connecting Big Mac to the machine once more grew off-white, and the sight of that virile fluid being taken from her brother again finally tipped her over as well. Applejack cried out alongside her brother's moan, her hips rocking back on him. Her fluids started streaming out onto the muzzle so pleasing her, her clit winking constantly as it seemingly tried to escape the still-constant licks upon the now-pulsing nub, though only sending a whole new wave of pleasure rolling through her with each wink and lick.
Finally, after what felt like forever for both but was only a matter of twenty seconds for Applejack, she came off her high, glancing up at the collection cylinders. The canister was still filling up. "Holy hay you cum a lot bro..." Applejack moaned, still rocking her hips against her brother's muzzle as he managed to fill the first one almost completely.
"Mmhm..." Big Mac surprisingly, though weakly, acknowledged, his hips still jerking with each weaker pulse of his member, with both eventually slowing again. Applejack had cum a lot too it would seem, her brother's whole muzzle glistening with her mare-juice in the artificial light, a small puddle of what he'd missed of Applejack's extensive gushes having formed from her own intense orgasm. "Y-Y'too sis..."
After a while of both being suspended in post-orgasmic bliss, Applejack felt Big Mac stop licking on her and pull away, a small string of her fluids and his saliva connecting his lips and hers for a moment, before promptly collapsing to the ground. He was exhausted physically from all of the thrusting; still though he felt that need in his pelvis, knowing he wasn't done quite yet even if he was softening. Applejack saw it too.
"C'mon bro, y'ain't quittin' on me yet, are ya?" Applejack asked, reaching over to the switch and increasing the voltage and rate of the shocks, making Big Mac gasp, feeling himself growing hard once more as his hips involuntarily jerked harder into the air with each shock. Before Applejack knew what was going on, Big Mac had grabbed around her hips with his forehooves, pulling gently back on her.
As she looked back, Applejack realized that Big Mac had positioned himself so he was laying on his back and could hump into the air instead of having to support himself on his now-very-wobbly legs, his muzzle ending up perfectly beneath her crotch. He was exhausted, yet still hardening and throbbing in the machine, spurred on by Applejack's heated scent and the flavor of her thick, fertility-telling fluids, as well as the moderate-strength shocks now rolling through his hyper-sensitive member and the still-harsh suction. "Y' still got a canister to tot'ly fill...an' a mare to satisfy again."
"N-Nnnope, not done." Big Mac assured half-heartedly, still though giving another tug on her hips; "...an' you ain't neither."
At this point, Big Mac was feeling very drained and tired, but still the machine suckled and shocked him to full hardness again within thirty seconds of his second orgasm, working on siphoning more of his 'milk' out of him and making him totally dry as it was designed to. Applejack meanwhile took him up on his invitation, slowly bending her back legs, lowering her rear down and making her lower lips meet his muzzle as she partially sat on him. She let out a deep moan as she instantly felt his muzzle sink deeper than before and spread her wider, his wide tongue in kind starting to prod and lick deeper within her, trying to at least partially satisfy her deep, burning need.
So it went again; Big Mac lapping away at his sister's honeypot, and the machine trying to claim what could be another couple billion foals from him. "Holy hay bro, much as yer cummin' y' could get every mare in Equestria pregnant, then have some to spare...!" Applejack said, earning a quiet groan from Big Mac and an extra hard thrust of his hips into the air. That was...quite the thought indeed, wasn't it?!
~
A few minutes later of the intense stimulation and another couple orgasms from Applejack, her thick mare-juice now coating his whole face in her pleasure, Big Mac again felt that familiar pressure of orgasm building, along with the exhausted pain of overworking himself. He felt that pressure welling up, welling... and finally with one more shock, he tipped over once again. Big Mac moaned into his sister's pussy as he flared and another, much smaller and thinner load of his cum was drained from him, fatigued pain and some pleasure mixing together through him as he slowly started filling up the last of the canister he'd left empty; Applejack watching in pleasure as the last of her brother's essence was stored away, the cylinder finally topping out just a smidge short of its capacity limit.
After Mac finished twitching, his hips falling still, Applejack figured he'd had enough as he gave a desperate whimper, wordlessly begging her to stop the machine, with him not capable of much more. His member was beyond sensitive now, and the sensations on it were no longer pleasurable, instead becoming very uncomfortable. She reached up to the machine and flicked off the switches and dialed the knobs back to off, before switching the machine itself off, hearing the electric hum from it slowly fade until all that could be heard were the desperate pants of her and her brother's breathing.
Big Mac virtually collapsed once the suction stopped, all tension loosed from his muscles as his flaccid member quickly slipped free from the cup and slapped against his belly. Not a trace of his cum could be found on it, his penis completely dry save the teat lubricant; the machine had taken everything he had to give, and his well-emptied member was swiftly making its way to the sanctuary of his sheath.
Both simply recovered for a few minutes, Applejack resting while her lips were still satisfyingly parted by her brother's muzzle, and Big Mac simply laying there, drained of everything he had but utterly satisfied as well. He'd never been so totally and completely emptied of his seed like that, his breeding instincts feeling so relaxed now in ways that previous orgasms outside of a flesh-and-blood mare had never left him.
Applejack soon stood, approached the machine, and looked at the container that held her brother's stallion-milk, looking in awe at just how pent-up he'd been and realizing how much he'd needed this. "Wow, bro..." was all she could mutter out, before going up to the container with his thick load, sitting, and removing the collection tube and lid from it. She looked at the container she now held in both hooves; looked at the thick, virile fluid it contained. She felt drawn to bring it to her lips. She had to at least taste what her brother had worked so hard on making for her. It would be right rude not to.
Applejack wrapped her lips around the rim of the container, and Big Mac watched in awe as she first sipped it, swishing it around her mouth, before she started to drink his cum; gulp after gulp of his foal-cream leaving a nice, satisfyingly warming sensation down her throat and into her belly. Applejack found that his flavor wasn't as bad as the other few stallions she'd been with and given orally to; having a gentle, milk-like flavor with a hint of apple alongside a universal, pleasantly-musky taste she could only describe as 'stallion' instead of the highly bitter, or outright gross seed of the other stallions.
Before long, a quarter of the container's contents were gone, and only then did Applejack stop to gasp for breath. She felt herself getting horny again from the thick texture of Mac's seed sliding down her throat, her body once more wanting to be satisfied from the scent and flavor of a stallion's virility. Mac was one step ahead of her.
"Mmm Mac, yer 'milk' tastes pretty darn good..." Applejack said before Big Mac suddenly yanked his sister back onto his muzzle as she stood and started to roughly lick inside of her once more, earning a surprised squeak followed by a quiet moan.
"'s'ok Mac, y' don't have to... ooooh Celestia..." Applejack said with a moan, trying to pull away at first, but finding Big Mac held her firmly against his muzzle, Mac giving a muffled 'mm-mm' and earning a harder moan from her as he then targeted her now-winking clit. It would seem he wasn't done with her after all, and Applejack's body seemed to agree, her hips starting to grind against her brother's muzzle again, her clit getting into its instinctive pattern of winking as her pleasure started to very quickly rush towards another orgasm.
"M-Mac? Oh by the Sun...are ya even listenin' anymore...?"
Revenge of another on her was never so orgasmic for Applejack as it was that day.
Author's Note
Apple Bloom saw everything, and needed a serious talking to after. She shouldn't have explored those funny lights and sounds late at night...

Was this convoluted and exaggerated? Maybe.
Wrong? On so many levels.
Milk-ilicious? Oh fuck yeah.
