The Milk Factory

Bright light hit the back of Almond’s eyelids right on schedule, stirring her fully out of her daze and into wakefulness.

“Rise and shine, Almond!” cried Scrub Buddy from next to the switch.

Blinking the crud out of her eyes, she raised her head off of the large foam cushion she’d bought to use as a pillow and craned her neck aside to face him. “Mmm, morning.”

“The usual?” he asked, already making for the stairwell.

“Yep,” Almond replied.

As the yellow and orange earth stallion made his way up to her, Almond observed the factory floor, her unchanging environment for the majority of the past year. Nopony else was here yet, as it was still early.

However, Almond herself had plenty of presence. Affixed to one of the second story milking stations, she wore nothing but her proudly earned cutie mark, a full milk bottle next to a smaller mountain for scale.

For her breasts had expanded to surpass all expectations. Hers were the largest teats known to science, beating even an Ursa Major’s. Far from dangling, they reached all the way to the floor, thousands of pounds of soft flesh ripe for fondling by passersby. Even then, there wasn’t enough room, as above, they pressed up into eachother and into the steel mesh from underneath. Both were twenty feet in diameter, tipped with huge pink nipples that jutted into air, each nub the size of a pony.

A part of Almond actually wished they hadn’t stopped growing, but this much would do. At this size, she actually made as much milk as all the rest of the factory's livestock combined!

Soon, Scrub Buddy, the maintenance pony who she worked with on weekdays, reached her. First, he pulled her cushion aside and tipped a bottle of mouthwash towards her open lips. After she swished a bunch, she spat out into a metal pan. Then, he held it underneath her backside so she could pee.

That out of the way, they could get to the nice part. Setting the pan aside, Scrub Buddy grabbed a sudsy washcloth from the supplies he’d carried up here and began to gently run it all along her coat.

Sighing in relaxation, Almond savored the pampering, letting her mind empty as he plied his own talent to her body, reaching into every nook and cranny to sweep the sweat away. He then shampooed her mane and tail with her preferred brand - lilac scented – before rinsing everything off and toweling her dry. Finally, with practiced ease, he brushed her, getting out any tangles in her hair and giving her an enticing luster.

“There,” he said, stepping back towards the stairs, his gait subtly different.

Almond needed only look at his undercarriage to spy the reason; he was sporting the beginnings of an erection.

“It’s still cute how much you enjoy this,” she quipped, smiling at him.

“What can I say; the only thing I like more than a hot filly with huge teats is a refreshed hot filly with huge teats,” he said, returning the smile.

Alas, he wasn’t going to fuck her just yet, regardless of her green nametag or how wet she already was. Scrub Buddy wasn’t even close to being finished cleaning her, as Almond’s head and torso were only a tiny fraction of her body. After going into the next room to put everything away, he quickly returned with a rolling mop bucket. The mop was the only way he could reach everywhere.

Almond watched him work, enjoying the accompanying sensations shooting through her boobs as he cleaned them off with sudsy water, then dried them. Other ponies were arriving now, both livestock mares and maintenance workers, but they paid the scene no special mind. This was a daily occurrence, after all. Following this, Almond would probably start chatting with them. She wondered if anyone new would be in today.

Presently, though, she had to bite back a squeak as Scrub Buddy reached her right nipple, the pair of them having been saved for last. Despite their size, they were awfully sensitive, and it took a supreme force of will on her part not to start leaking precious dairy all over him as he cleaned it, and then moved on to her left.

Just as Scrub Buddy finished putting the mop away, another maintenance stallion, Switchboard, trotted in from the production floor. “Okay, the pumps are live and ready,” he said. “Let’s get Almond started.”

“Right,” Scrub Buddy acknowledged, moving with him to the rack where they rested.

Naturally, given their enormous size, the glass cups for her nipples needed to be custom-made to match, and they fed into hoses twice as thick as a pony’s leg. It took an earth pony’s strength to lift one, and the two stallions each hefted one onto their back before walking them towards her. Almond could hear the rush of air flowing through them, a testament to their high-powered, sublime suction. She tensed in anticipation.

Without preamble, they pushed the cups against her areolae, backing away as they stuck fast. Gasping, Almond’s milk shot out instantly, white cream coating the glass and flying down the hoses like the output from twin fountains. This was what she’d been born to do: make lots and lots of milk for all of Equestria to imbibe. She loved this feeling, the tingling, bubbly release.

There was no chance she could keep up this rate for long without the nutrient solution, however, so Switchboard left to go let the others know to turn that on. Her humongous teats demanded large quantities of the stuff, and the dozens of extra feed tubes that snaked under the floor, implanted directly into the pair of them, certainly delivered.

Meanwhile, Scrub Buddy watched her. She couldn’t tell from this angle, but she was positive he had a full-on, raging boner at this point due to prior experience. His own job done for now, he was free to indulge, and quickly rushed back up to her.

While she waited, the rush of milk spraying out of her slowed down to a trickle as she was nearly drained. Of course, a trickle for her was still a faster rate than any other mare in the factory could boast, but she didn’t want to make a trickle, she wanted to make a deluge.

Thankfully, Almond soon felt the nutrient flow kicking in as her hunger and thirst faded away. Now with a substantial supply to work with, her immense teats audibly sloshed and gurgled as they began producing in earnest, many more gallons of unspent milk welling up inside her glands, begging to be shared. And share she did, moaning as her breasts really kicked things off, the flow of milk now bursting forth steadily increasing and showing no signs of stopping any time soon.

These first glorious moments of bliss never failed to make Almond terribly horny. And while her boobs felt incredible, the rhythmically fluctuating suction drawing out more and more and more, her pussy was terribly neglected.

Scrub Buddy approached as if on cue, his hoofsteps echoing behind her. No words needed to be exchanged; she just leveled a needy look over her shoulder at him and held her tail off to the side.

He wasted no time in mounting her, the familiar shape of his cock penetrating her slick walls. “Ah, I really needed this today,” he said.

“So did I,” Almond confirmed, basking in the sensations.

Beginning to thrust, Scrub Buddy moved at a methodical pace, lighting her nerves ablaze with his touch inside and out. This wasn’t lovemaking; this was two ponies addressing the primal desires of their bodies, modified though Almond’s was.

Still, it was Scrub Buddy’s nature to care. “You feeling good?” he asked, his husky voice right next to her ear. “I wanna see you cum like crazy, so let me know what you need. Should I bite your neck again?”

As he continued thrusting, his hot length scraping her pussy as his hips slammed into hers over and over, Almond’s tits kept on pumping out milk, a duet of ecstasy that buoyed her higher, her heart racing. He’d fucked he so many times by now that he knew exactly how to move to drive her wild.

But he was still holding back, taking it slow. That wouldn’t do! “N-Not yet. I’m used to this, you can go way harder. I can’t - oooh - cut loose until you do.”

“If you say so,” Scrub Buddy acknowledged. Then, he followed through, grunting as he slammed into her with his full strength.

Since she was locked down, all that delicious power went right through Almond’s core, and she cried out, her nipples making clear her approval with an extra large splash. “Yes! Don’t stop!”

Scrub Buddy obliged, losing himself in frenzied pistoning. Almond felt each inch of motion inside her and against her, his balls sending a shock up her spine whenever they bumped against her swollen clit. Each stroke reverberated along into her boobs as they continued to disgorge her rich milk at an accelerating pace.

“I-I’m getting close!” Almond exclaimed, egging Scrub Buddy on as she tensed beneath him. She craved this, badly, constantly. “Do it now; unleash your urges, fill me up!”

Groaning, her words having the intended effect, he hilted his length inside her, his flare widening as his dick stiffened even further. He gripped her sides tightly with his forehooves and bit her neck as promised. “Fuck, Almond, take my seed, then!”

As Scrub Buddy spasmed atop her, she could feel his cock heedlessly pulsing as the first wad of his cum coated her womb. Between that, the fire from the bite, and the ceaseless pull of the suction cups, almond crested her own peak, seeing stars.

The magnitude of Almond’s climax sent vibrations through the floor, utterly dwarfing her stud’s release. If her cunt was the switch, then her teats were what it activated. Almond’s mouth hung agape as a roiling pressure built and built before blooming into being at last. In that moment, she wasn’t a mare, but a glorious machine of flesh, with one simple purpose: erupt.

Head empty, beset by sensation, Almond’s teats roared and flooded the cups with milk, so much so that her nipples were completely obscured by white, the pumps struggling to manage it all. Her back arched as she spasmed and pulsed with life.

Scrub Buddy came down from his orgasm first, his dick softening as he sighed and pulled out on wobbly hooves. Barely coherent under the continued rush of purest bliss, too busy blasting out a watertower's worth of milk, Almond dimly registered Scrub Buddy slapping her flank. “Keep up the good work,” he encouraged.

After wiping himself off, Scrub Buddy returned to his post, leaving Almond to continue doing her own job: endlessly gushing milk. Almond's only reply was a moan.

Once her climax and afterglow had faded, Almond was able to resume business as usual. Not many ponies showed up for sex in the morning, so even though she was one of the more popular mares at the factory, Almond mostly just relaxed, lactating at a more sedate pace (relatively speaking). Meanwhile, her friends, including Candlewax, began to arrive to get hooked up for milking themselves. They talked about all sorts of things. Local gossip, celebrities, current events, and what they were up to themselves. Almond obviously didn't get out at all, so she lived vicariously through others. The physical pleasure was 100% a worthwhile tradeoff. Besides, she could still read a book or magazine somepony brought her if nothing else was going on.

However, a few hours later, something quite unexpected happened. Meg trotted in, leading a set of very familiar faces. "There she is! Kind of difficult to miss, actually."

"No way!" Almond exclaimed, grinning ear to ear. "Dad! Bros!"

Her family had actually come to visit! Her mother and Filbert were absent, but those two were almost always swamped with work, so that was understandable. As for the rest of her family, they were mostly staring at her, struck dumb and unable to find words as Meg retreated back to her desk.

After a few more seconds of this, Almond spoke up again, coy. "I know, I tend to make an impression. Take your time."

"It's just..." began little Peanut, her youngest sibling, orange eyes boggled. "They're so big."

"We all read your letters, and knew that livestock mares were already huge, but damn, sis," said Cashew, whistling once. His roguish antics caused no end of trouble. "Those are certainly knockers. You could probably knock down a house with those."

"That's our sister!" Walnut chided, his scraggly tail flicking. "We shouldn't be ogling her," he added, face red as he turned away.

"I imagine she doesn't care," said Macadamia, studying her body intently. "This is actually giving me ideas for my next painting, should've brought a canvas."

Pecan just sighed and waved up at her, ignoring the others. His coat and mane were the same color as Almond's, such that folks often mistook them for twins.

"Boys," went her dad, punctuating his statement with a clear of his throat. When all his earth pony sons present shut their mouths, he continued, making eye contact with Almond. "At any rate, hello, dear. It's great to see you! How've you been?"

"I've been great, Dad, thanks," Almond answered, her spirits already warm with nostalgia. "Not much has changed since the last update I sent. Still making enough milk to feed multiple cities, still helping colts feel good."

Walnut's ears clamped tight against his head. "Don't say that part aloud!" he insisted.

"Why not?" went Cashew, impishly studying his brother. "It's part of her job."

"I thought her job was making milk?" Peanut asked, head tilted sideways as he pointed at her super thick nipples. "Look at how much is coming out of her; she could probably fill a swimming pool in fifteen minutes!"

"You'd have to ask somepony in production for the exact numbers, but that's probably true," Almond confirmed. "But Cashew is also right."

Her dad took the reins of the conversation back. "Either way, we're very proud of you, Almond," he said, the faint lines on his face crinkling with his smile. "And we wanted to tell you as much in pony."

"Yeah, for real," said Pecan. "All I do is hit things properly," he said, indicating his hammer cutie mark.

The others all hummed in affirmation.

"Thank you guys, really," Almond said, fluttery with appreciation. "Seriously, you didn't have to do this, come all this way just for me," she added, just grateful to see them all again. "I feel like I need to pay you back somehow."

Dad shook his head. "Nonsense, you already send us the vast majority of your pay! That alone has been a huge help; we were even finally able to get the funds together to afford Macadamia's art school tuition, remember?"

"Thanks so much for that, again," Macadamia himself added happily, his green eyes sparkling.

"Getting to see my favorite sister is enough, really," said Walnut.

"Also, what more could you even do, trapped in place like this?" questioned Cashew, pacing around her rack slowly. Then, he cracked a sly smirk. "Well, other than letting us fuck you, that is."

Pecan instantly began sputtering with laugher. Their dad balked, to the point he forgot to scold Cashew's language like usual. Walnut nearly choked. Macadamia barely reacted at all. Peanut was stunned.

Almond, for her part, after she got over the suddenness of Cashew's suggestion, genuinely considered it. That was something she could do to show her gratitude. She'd never thought about having sex with any of her family members before, for obvious reasons, but the idea didn't disagree with her. She opened her cunt to random strangers; if anything her father and brothers were ponies she already knew well, and wouldn't try anything untoward. And her being here in the first place was testament to the benefits of Almond deciding to follow unexpected paths.

"You know what? Sure!" Almond said, her tail swishing back and forth. "I'd be a liar if I declined. I'm all green, which means I'm fair game."

"For real?" Cashew blinked up at her owlishly. "I was just joking!"

The rest of her family could only stare, unable to believe what they were hearing.

"You'd do that!?" Peanut exclaimed. "But isn't incest wrong!? My teacher told us that in sex ed class, it leads to, um, birth defects and stuff."

At this, Almond merely shrugged. "I've got an implant, so I can't get pregnant, and it'd genuinely be a nice treat, a good way to thank you guys."

After a beat, Dad gave his two cents, frozen. "I'm not sure how I feel about this. Even just knowing you would is..."

"Yeah, I dunno either," said Pecan, shifting back and forth indecisively. "The flesh is willing but the mind is concerned."

It seemed as if her family needed a better argument before they'd be convinced. Fortunately, Almond had one, the same she used whenever folks were hesitant. "Think of it this way, I'm not really an independent pony anymore, just livestock. Talking milk manufacturing equipment. It can't be incest if you're just relieving yourselves with a machine, right?" she posed. "So long as you don't break me, you'll even be helping me do my job at the same time, and I can always use more assistance!"

"A valid point. Shit, I say we take her up on it," said Cashew. "The sight of all these busty mares locked in place has me all riled up. But why should we go for you instead of somepony else?"

Here, Almond sent him her best lidded 'come hither' gaze. "Because I'm popular enough that I've been training my core muscles to really wring out every. last. drop. It's rude to keep a stallion waiting, after all."

"Well, I'm sold," said Cashew matter-of-factly. "How 'bout it bros?"

Walnut looked like he could barely contain himself. "Yes," he said without hesitation, surprising Almond. "I was hoping nobody would notice how hard I was getting from the sight of her. To tell you the truth, I've had a crush on Almond I couldn't act on for years, and that was before she grew boobs bigger than carriages. It's taking all my willpower not to just bury myself in your cleavage, sis."

Almond's brows rose. Walnut had always been a tad skittish around her growing up, but she'd never suspected a crush. It was actually a bit flattering. "Well, there's no need to hold back any longer, Walnut. Go for it."

That was all he needed. With a wordless, hungry cry, he galloped straight for her, leaping at the end to dive headfirst between her teats. Her laden bosom jostled around him as he wiggled deeper, most of his body already hidden in hers. She could feel his every enthusiastic little movement within her pillowy confines; it was nice, but probably way better for Walnut.

"And that's the ice broken," Almond said, chuckling. "Why don't the rest of you come on up here and get started? I can't tell from up here, but I imagine your cocks are all raring to go by now."

"Damn straight," said Cashew, who was already sauntering towards the elevator despite their dad's token protest of a raised hoof.

When Pecan silently followed, still watching Almond out of the corner of his eyes, Dad sighed in acceptance. "Alright, fine. I won't object," Dad said. "You do have your mother's best features. And what kind of father would I be if I didn't help my baby girl when she asked?" With that, he too joined Cashew.

Excluding Walnut, who was still sending ripples of arousing touch through her breasts from his position smooshed inside them, that just left Macadamia and Peanut. "I'm more into pegasi, to tell you the truth," said Macadamia as he peered around the milking floor. "I'm probably going to find another mare, if that's okay, Almond."

"Oh, that's fine with me," Almond said, waving her ear as if it was a hoof. She wasn't disappointed; the whole point was for them to enjoy themselves, after all. "Have fun, Maca!"

Peanut, meanwhile, was approaching her teats. With wonder and curiosity, he reached up to touch her far more delicately than Walnut was, slowly running his hoof across her mammary, moving carefully closer and closer to her areola. It was cute, and such a tease!

It was at this point that the others had reached the second floor, Cashew, Pecan, and Dad all approaching. Almond raised her tail as she turned her head. "Alright boys, who wants to go first? I'm ready for you; no need to be shy."

The three of them traded looks. Pecan stepped forwards. "I will," he said, slowly circling her body like a predator about to pounce, examining her from every angle. As he did, his cock fully unfurled from his sheath like a lewd flower blooming into view, ready to copulate.

Pecan bit his lip, closing the distance. He caressed her with a roving hoof, touching her chin, neck, stomach, hips, flanks, and butt, setting Almond's skin ablaze. "I love this, having a mare completely at my mercy. Unable to resist," he purred. "Normally my partners take some convincing, but you're just always like this."

"Yeah," Almond confirmed, her heart beginning to race in anticipation. "Feel free to take advantage of me!"

With Dad and Cashew watching, equally aroused, Pecan did just that, straddling her before thrusting his dick past her vulva and into her needy core. Both of them moaned in unison.

Not bothering to start slow, thinking only of his own gratification in a way that make Almond delighted to just be used, Pecan humped her feverishly out of the gate. Almond had been with so many takers at this point that she'd become an expert at feeling the differences in the shapes of their stallionhoods. Pecan's wasn't especially large, but his veins were pronounced, scraping at her sensitive pussy like a ribbed dildo with each pass.

To increase both their enjoyment, Almond did as promised and squeezed herself around her brother, the better to feel every last bit of his heat and shape. Pecan stiffened even more as she exhaled breathily. And Pecan wasn't the only sibling driving her arousal higher. Walnut and Peanut continued to enjoy themselves groping her bloated teats, which continued their unceasing, unparalleled release. Walnut seemed disappointed every time he needed to squirm out of her cleavage to breathe.

"Oh, wow," Pecan said, his thrusting not pausing at all. "You weren't kidding. This feels so good, Almond. I could cum any second now."

Almond wasn't all that close to orgasm herself, so she focused on flexing her torso into the best angle for him, aligning their bodies. "Then just do it, Pecan," she ordered, a sensual reverb in her voice. "Leave your mark inside me, your helpless fucktoy~"

Struck speechless, Pecan instantly forced himself as deeply inside her as he could and held her tight, his throbbing cock depositing Almond's first ever incestuous creampie into her accommodating womb. Combined with Scrub Buddy's load from this morning, Almond was delightfully full, but still had room for more.

Even after a minute passed, Pecan's arousal hadn't dimmed, and his dick was still as hot and hard in her pussy as before. So it was with great reluctance that he pulled out, taking his enjoyable weight off her back.

"Aww, why'd you stop?" Almond asked, shaking her mane back into shape. "My milk isn't about to run out any time soon, but I was thinking you'd want me to wring you dry!"

Pecan took a few more seconds to gather his breath. "I'm giving the others a turn with you first. Mom always taught us to share our toys, remember?"

"True," Almond echoed. It didn't hurt that being objectified drove her thirst higher, mixed fluids dripping out of her and trickling through the mesh floor. Between that and her other siblings' ministrations below, the mighty rivers of milk cascading free from her boobs were gradually widening with each passing second, an endless abundance of creamy sustenance. Teats existed for one purpose, after all, and Almond was far more teat than mare.

As Pecan retreated, sitting down across from her on her pillow cushion to stroke himself as he watched, Cashew took his place. "Get ready, sis. 'Cause I'm gonna take advantage of your newfound sluttiness and cut loose."

However, Cashew did the unexpected and approached her from the front. While the sight of him was admittedly enticing, musky pheromones simultaniously swirling through her nose, her ears still folded apologetically. "Ah, I'm sorry, you wanted to facefuck me?"

"Yeah?" Cashew questioned, still shuffling closer until his glans was poking against her muzzle, his body shadowing her head. "I thought I could do whatever I wanted with you?"

"You can," Almond confirmed, resisting the urge to start licking. "It's just that I'm not the best at oral stuff. I haven't been able to supress my gag reflex yet, so I might bite you if you go too deep, which is no fun for either of us."

"Damn," Cashew said with obvious disappointment, backing up. "I was really looking forward to getting my dick down your throat."

"If that's what you want, you can go fuck my friend Candlewax right over there; she's really good at blowjobs," Almond said. Once Cashew had retreated enough, she made eye contact with her. "Thanks for not interrupting our family reunion, by the way."

"No problem," Candlewax replied, Almond's busty comrade also continuing to lactate in place. "Figured it would've been rude. Also, Cashew, was it? Almond's right, if you wanna facefuck, I'm your mare. Almond's specialty is actually anal."

Hearing this, Dad's brows rose in interest. He looked at Almond in a new light. "Is it, now...?"

"Uh-huh!" Almond confirmed, peering back at him as Cashew turned to sweep his gaze over Candlewax. "I don't eat solid food anymore, so my ponut is always nice and clean. Best backdoor service in the building!" Almond proudly declared.

This got her dad's attention. "Is that so? I'll have to try a round or two of that myself. I've missed anal; your mother never lets me do it with her that way."

Almond shuddered a little there. "Okay, letting you fuck my ass like every other colt is one thing, but I do not need to know about my parents' sex lives, thanks," she said.

"Fair," he replied, chuckling under his breath.

As Cashew left to go stuff his meat down Candlewax's eager gullet, Dad trotted up to her, grabbing her tail and yanking it to the side with the perfect amount of force, exposing her goods to his newly lustful stare. "If you hadn't chosen to become livestock, I never would have thought about you in this way, Almond. But now that you are... We're going to have some real daddy-daughter bonding."

"I'm ready for you," she confirmed. In front of her, Pecan watched, ready to pick up his self-care as the show began. She winked at her brother before peering back over her shoulder, silently urging her daddy to just get fucking.

He obliged, lining up his cockhead with her asshole before breaching her other entrance with a single mighty motion. Almond gasped.

"Goodness, you do feel great," Dad declared before starting to slide back and forth, in and out, her tight ponut squeezing around his girth and being stretched in turn.

"T-Thanks," she replied, heart racing as her motor kicked back into gear, filling her with building electric bliss as her dad filled her guts. "That's the stuff."

He was silent for a bit, just reveling in her body - as he should - before speaking up again. "Such a beautiful mare you grew into. So healthy, too."

Her father's cock was scraping against erogenous zones which had yet to be touched so far today, and the unique, swirling sensations stoked her inner fire hotter and hotter. Almond moaned and arched her back, her titanic teats greedily sucking up liquid energy as they rumbled and shook, blasting out milk like storm clouds on monsoon day.

Both Pecan and Dad increased their pace. "My stars, I needed this," Dad uttered. "You know, I drink a lot of milk to support my aging bones. I wonder how much of it is yours?"

"A big portion, I'm sure," she confirmed. "Why don't you keep thrusting like that, help me make that fraction even larger? Because I'm - mmmph - approaching the edge, and then you'll see a flood."

Here, her daddy groaned, a sound she'd never heard him make, right beside her, inside her, reverberating through his body into hers. "If you goad me like that, Almond, I'm gonna—"

Stiffening, holding onto her body like a lifeline, he came, shooting rope after rope of jizz - the same jizz she'd been made with - into her thirsty cavern. That entrancing sensation of satisfaction set Almond rocketing high, lighting the fuse to the bomb that was her release. "Fuck, fuck, fuck, I'm about to e-explode!"

She lurched and bucked beneath her daddy's bulk as she came, her breasts kicking into overdrive again as the hoses were completely inundated with thick, rich milk. Almond dimly registered the pumps in the other room make a scraping sound from the other room as they struggled to deal with the ludicrous magnitude of her climax. And what a climax it was. Almond saw stars as her own overstimulated nerves struck her dumb with a barrage of sensory wonders, centered on the point where their bodies met. She screamed, uncaring who heard.

Almond recovered her composure just in time to see Pecan walk up on shaky legs to give her a facial, marking her coat with his essence, visibly claiming her. She managed to shut her eyes before she got cum in them, but gladly welcomed the painting everywhere else. Dad had already pulled out at this point, and once Pecan finished, he too retreated off to the side, panting.

"Who boy, that was good. Nice job, sweetie," Dad said, catching his own breath.

Almond just smiled, still breathing hard herself, and licked up some of Pecan's juice to taste. Glancing down at her teats, she saw some of her milk had actually leaked out of her areolae and all over the floor in wide puddles. A janitor had already put up a wet floor sign and was cleaning it up, but poor Peanut had been soaked from head to hoof, his mane and tail plastered to his body. He and Walnut, the latter having pried himself free from her teats at some point, were making their way upstairs.

"Never thought I'd get off to watching my dad bone my sister, but here I am," quipped Pecan.

Now settled back into her usual level of near-perpetual arousal, Almond threw in her own two bits. "We're all different ponies than we were a year ago. If you went back in time and told me then that I'd soon have teats the size of dragons and just as ferocious, I would have thought you were insane. But here I am."

"There you are, indeed," a husky voice intoned.

Almond twisted to look behind herself again. It was Walnut, she'd hardly recognized his tone, so laden with lust and love, no longer hidden. He looked at her in a way few of her partners ever had, and it sent her heart fluttering anew, the pulse of blood in her veins matching the rhythm of hew twin torrents. "I take it you're ready for the main event, now?"

"You bet, Almond," Walnut confirmed, trotting over. Her brother's studly pole bobbed beneath him as he moved.

Face flush with emotion, Walnut was about to violate her, but stopped, hesitant. "Oh, you've got semen dribbling out of you. Between that and the fact I already busted while I was buried in your teats - Tartarus, that was good - I'm having trouble keeping it up. But I saw you as attractive first, dammit, and I'm not missing this chance!"

His passionate words striking a chord with Almond, Walnut sighed nonetheless. "Can we get somepony to clean that up first?"

Scrub Buddy was already there, brandishing a fresh towel from his customary position in the background. "On it," he said. As he began to delicately get her ready for round four, Scrub Buddy added a brief explanation. "I've been on deck this whole time; my job is taking care of her."

Dad nodded to him in gratitude. The rest of Almond's brothers had converged, too, ready to watch. Macadamia and Cashew had both finished with their own livestock mares at this point, and wore blissful post-coital smiles. Besides Walnut, who eyed her with burning desire, only Peanut currently sported a hard-on, his cute penis already slick with her milk.

"Anyway, try to hold back a little bit, okay Almond?" Scrub Buddy chided as he wiped the remaining semen off of her muzzle. "We don't want you wasting milk, remember."

"That's fair," Almond said as her caretaker switched to wiping the excess off of her holes. "Sometimes I can't help it though; my girls are simply too good at what they do!"

Scrub Buddy rolled his eyes, then stepped away, finished. He tossed another towel to Peanut before gesturing from Walnut to Almond. "Alright, have at her. I can personally confirm you'll enjoy the ride."

Walnut audibly swallowed, reaching her rear end at last, where he began to tenderly caress her flanks. "After all these years of dreaming of you, I can... I can..."

"You can make love with me," Almond confirmed, raising her tail once more, an invitation.

Walnut pounced. "Almond!"

She cried out as her brother hilted himself on the first thrust. Goodness, his dick was so hard and so hot, his previous disfunction gone without a trace. Even without his confession earlier, Almond would have suspected Walnut was truly into her from that alone. At first, he didn't even move, just taking in the moment as her cunt coiled around him. But this didn't last long, and he abruptly transformed into a voracious beast, satiating himself as he jackhammered her ever thirsty pussy.

Almond's pleasure center meshed perfectly with his as he groped and grabbed at her every curve, their sibling bodies very compatible. In sync, they gasped simultaneously. His affections were conveyed freely, flowing through his movements just as readily as her milk flowed through the factory. Everything else faded away, the world reduced to just the two of them, and their lascivious coupling.

Walnut groaned in ecstasy as he relentlessly pounded her. "Mmm, I don't care if it'd be wrong, I really wish I could knock you up, breed you, make you mine."

"I've - ah - thought about it," Almond said, fire in her veins. "But I'm not exactly in a position to be raising foals, yours or otherwise."

"You could - oh yeah - put them up for adoption, or have the stallion take them," Walnut proposed, the sensations he was sending rippling through her core with each pass making it hard for Almond to focus on his words. "Besides, don't you want to find out how much more milk you could make with those hormones in your system, how much more massive you could grow? Celestia, I'm about to cum just picturing it."

Almond smirked beneath him, realizing just how to send him over the edge. "You like that thought?" she uttered, voice low. "My jugs, even more enormous than they are now? Twice or even three times as big? At that point, this factory - and every last creature in Equestria - might not be able to handle just how much milk I could really make. Why, maybe this whole factory would get drowned by my release."

That did it. Walnut screamed her name as he came, painting her womb with the third batch of thick seed her pussy had gotten today as he bottomed out inside her and spasmed. Almond could tell from how much her baby oven swelled that Walnut's load was especially copious, a product of his affections. And while she didn't climax along with him, her teats still reacted below them. It felt splendid, her milk fountaining forth from inside her with the force of fire hydrants, the nutrient solution fueling Almond's bliss. Not quite the picture she'd just boasted, but getting there. She could feel each labored breath Walnut took as his ejaculation soon tapered off, her brother lover moaning low in satisfaction as his strength gave out and he laid down atop her.

"I love you so much, sis," Walnut reaffirmed, nuzzling against her neck, cuddly. A chorus of (perhaps misplaced) 'awws' resounded from the others.

"I love you too, bro. Just... not in the same way," Almond said, apologetically.

"Good enough for me; I still got to have sex with you, after all."

"This is correct," Almond noted.

It was with great reluctance that Walnut eventually stood up and pulled his softening cock out of her after another minute or two of cuddling. This left only one colt left unsatisfied: Peanut. She turned her head to face him, expectant. At least until she beheld his conflicted expression. "What's the matter, Peanut? Do you not want to have sex with me, too?"

"Oh, no, sis, you're super attractive, and I'm very curious as to how it'll feel. It's just that... I'd be giving you my first time," he explained, bashful. "And I'm not sure if I want to save that for somepony else special."

Almond hummed and nodded in understanding. "I get that. Let me tell you something, Peanut. If you do decide to use me, you won't be the first pony to give me their virginity. The local schoolteachers actually bring their young mares and stallions here as part of their sex ed curriculum, so they have a chance to observe the process for themselves, and also try things out in a regulated environment if they want to."

His ears perked up at that. "Really? How many of them decided to have sex with you?"

"Out of the twenty-odd students in the class, two colts had me pop their cherries. Four more went for other livestock mares, I think. They didn't last very long, but I was happy to help them feel good," Almond answered, giving her brother a patient smile.

As Peanut's face scrunched up in thought, Dad chimed in. "There's no pressure, son. We won't care either way, promise."

"Yep! I'll continue to tease you regardless," said Cashew, giving Peanut a noogie, even as the colt flailed his hooves in protest.

Once he'd gotten Cashew to back off, Peanut resumed thinking. After a long moment, he faced Almond. "I think I'm going to pass."

"Okay," Almond acknowledged, only a tiny bit disappointed. "But if you ever change your mind, I'll always be here."

"She can be your rebound if things go badly with your first marefriend," Cashew noted. Calling his tone 'sagely' would be a stretch.

Peanut blinked at him, nonplussed. "If you say so."

After that, Almond and her family spent some time engaging in more normal conversation for a little while, now that they'd expended their horny energy. She asked what they'd been up to, and vise versa, typical family reunion stuff. But eventually, they needed to leave, if only to check into the inn they were staying at.

"Wait, before we go, I have an idea, assuming it's okay with Almond," Macadamia chimed in.

Almond giggled at that. "Given what I just allowed, it's probably fine."

Here, Macadamia pulled out a black permanent marker. "Could we sign your body? I'll be a nice memento."

"Oh, like those sluts in the magazines, with the tally marks!" Pecan exclaimed.

"Or like when I broke my leg a while back, and everypony wrote on my cast," Peanut countered. "That'd be more wholesome."

Wholesome or otherwise, she was down. "Sure! What a great idea; now that you mention it, I'm shocked nopony's suggested this until now," Almond said. "It can be a new tradition!"

"Perfect. Do you care what we write?" Walnut asked. "I'm thinking Property of Walnut." He was already reaching for the marker.

"Not really, that's fine," Almond confirmed, thinking as he approached her ass again. "Actually, hold on, if I'm letting all the stallions do this going forward we'll run out of room on my flanks fast. My teats have way more surface area, use those!"

Dad's eyes lit up. "Ah, instead of a guest book, guest boobs."

Everyone sighed at that. Dad jokes were universal, there was no escape, even for livestock. Still, they did as Almond bid and took the elevator back down, where they took turns writing on her immense, soft breast even as she continued to churn out milk for the pumps. She couldn't see what they were writing but could sort-of make it out by feel. If she really wanted to know, she could ask somepony later. Once they were all finished, Cashew, Peanut, Macadamia, Walnut, Pecan, and Dad waved goodbye.

"Thanks for coming, guys!" Almond exclaimed. Then, she shifted from loud to sultry. "So, same time tomorrow?"
