Derpy goes to Barnyard Bargains with her family. She shares her milk with an employee, then later makes a pretty public spectacle of herself.
A little larger than in the previous stories, Derpy is still happy to share her milk with interested parties and grow, especially in so inspiring a location as the dairy aisle.
Unfortunately her target turns out to be so new in town that they don't fully accept how amazing Derpy's breasts are, even after experiencing them for herself.
A public demonstration of her awesome abundance is obviously in order.
Warning: Lactation, breast expansion, masturbation, very public lewd behavior.

Derpy always enjoyed having breakfast on the back porch, because it encouraged Berry and her to sit on the bench for a little longer once their daughters had finished eating and went to play in the yard. Doing the dishes could wait, then. In the privacy of their own home, Berry Punch was quite affectionate, so she enjoyed Derpy leaning against her. The bigger mare had her arm over Derpy's shoulders.
Even Derpy's breasts, each now slightly larger than her own head, didn't interrupt these moments of togetherness by demanding attention. The feeling of constant production was a pleasant background thrum, subtle but reassuring. Besides, a nice glass of her milk was part of every breakfast. She idly rubbed the side of her rack for a moment. "I'm happy, Berry." It might be a trite thing to say, but she liked to be explicit about how much she enjoyed the life they had built. Now that she was working as a mailmare, most mornings were spent in something of a hurry.
"Yeah," Berry nodded. "Feel like a winner every day." The big mare had a few customers for the products of her still, but otherwise stayed at home to look after the kids. Before settling down in Ponyville, Berry hadn't had a welcoming home or a supportive family at any point, so she was savoring things many ponies took for granted. "If I got stabbed today I'd say things ended on real high note."
Derpy rolled her eyes, pinching the top of her muzzle. "Couldn't you say something mushy like 'I wanna grow old with you'?"
"That would work," Berry agreed amicably. She grabbed a pitcher from the table, brought it to the nearer of Derpy's fat nipples and gently gave it a tug.
The flow of milk was nice and controlled. Derpy had let off steam in the shower earlier, and besides, actually giving milk for a meal was enjoyably satisfying, but didn't make her normal arousal spike any higher than the usual low simmer. Intellectually, she knew that they might pour out the pitcher's remaining contents later since her family probably didn't consume particularly more milk than others, but the demonstrable truth that her supply far outstripped her family's modest demands only made the situation sweeter.
Berry gave her boob a fond pat. "I'll grow old with you, sure. D'ya think your jugs will let you get all saggy and dried up?" She smirked. "Always more mouths to feed in the world. Grandchildren, maybe?"
Derpy grinned. Soothing warmth radiated from her great glands, as though they approved of the idea of existing forever to supply milk to the hungry. "Where'd that come from? Run out of ideas for teasing me about wanting to be huge, so now I'm gonna be the immortal princess of boobs?"
Slowly pouring herself a glass of milk, Berry took her time to answer. "Nah, the size stuff is still fun, it's not like it stops working on you. But you'd need a lot of time to get really huge. I've been browsing the fiction stuff at the library to help me come up with stuff."
"Stuff?"
"Well." Berry took a sip. "I already doubt the princess would be happy with a pair of tits the size of mountains within sight of Canterlot. Maybe you could relocate to the frozen wastes or the badlands, since you'd be more useful there anyway, but that's really just kicking the problem down the road for a while, and supposedly the princess wouldn't be so shortsighted." She shrugged. "Anyway, nobody wants to see you flatten cities or displace so much water it floods the coastlines so once you're too big for a cloud platform we'd have to get weird."
"Well, yeah. I obviously wouldn't expect to get that absurdly huge within my lifetime." And yet ... even imagining herself bigger than the mountains, so huge that even from outside Equestria she'd eventually encroach on it, that didn't feel too big. Derpy's mouth went dry as she asked herself if it felt big enough, a final goal to dream about achieving.
No.
"Weird, huh?"
"Y'know." Berry gestured vaguely. "Send you to space and and build the first off-world colony on your knockers, maybe find some alternate world or timeline nobody uses anymore, that kinda stuff. Get the world out of the way of your rack, yeah?"
"Yeah." Derpy swallowed thickly. While logistical problems were easily ignored in lewd fantasies and she generally got a kick out of being inconvenient for others, Derpy didn't want to hurt anyone or cause too much destruction, which had put something of a cap on how vast she could envision herself and enjoy it. She took a deep, deliberate breath and massaged the sides of her amazing breasts slowly to remain calm. Fortunately, it had barely been an hour since her morning shower and its associated milk release and awesome boobgasm, which helped in maintaining control.
She was usefully distracted by a shriek of delight as their daughters started roughhousing in the grass. The girls were surprisingly physically inclined for a pair of unicorns, but perhaps Derpy was harboring a stereotype. It probably mattered more that Berry was an imposing, physically powerful mare, and that she'd started first tickle-fighting and then play-wrestling with the girls as soon as they could walk with a degree of confidence.
Derpy got up to start cleaning up the remains of breakfast, enjoying the increasingly weighty bounce and wobble of her breasts. Maybe one day she'd be much too large for mundane tasks like that, but right now she simply enjoyed the way her rack already demanded slight adjustments to the way she moved while doing household chores. She bit her lip. First the rest of the world had to adjust around her boobs, and perhaps in the far future, the world would get out of the way, as Berry had put it. That was only right.
"I'll just put the dishes in the sink," she called out to Berry. Cleaning them could wait. Once their daughters had exhausted themselves, it would be time to cuddle. The girls already understood that Derpy wasn't quite like other ponies, but they mostly enjoyed how soft and comfortable her body could be. They were going to have to go grocery shopping as well, but since Derpy's appreciation for crowds grew along with her boobs, she wasn't in any particular hurry to do it outside of any sort of peak hour.
Getting the girls ready for a shopping trip wasn't much of a hassle considering the good weather they'd been having. By the time it got colder, the two of them would probably have the hang of dressing themselves without assistance.
"Get dressed, mommy!" Dinky and Ruby Pinch both giggled. Currently they were finding it very amusing to remind Derpy not to go topless outside their home. Perhaps they had a childish awareness of the fact that Derpy liked being looked at, which made it funny?
"I'll need some help with that," Derpy replied warmly. "Berry, you about ready?"
"Yeah." The bigger mare approached from the kitchen. "Packed some juice in case the kids get thirsty." Berry sometimes claimed to be particularly meticulous about details like that because she lacked any natural inclination towards care-giving.
Derpy was finding that notion increasingly questionable as the years went on. "Good thinking." She held out the top she'd selected for the day, then put it on until the fabric was bunched up on top of her boobs "I'll need some help with that."
Berry just rolled her eyes. She was obviously well aware that Derpy's rack wasn't nearly big enough to keep her from dressing herself. The problem was that the cow print tank top was the last doomed survivor of a generation of garments which had long grown incapable of containing Derpy and been subsequently discarded in tatters. It wouldn't be the first time that she had to leverage her considerable strength to help Derpy squash her tits into some poor, abused garment. Having her boobs treated so roughly by her lover was normally enough to get Derpy horny, which then might have been enough for her milk tanks to grow tight and engorged, sabotaging their efforts.
Derpy assumed that her breasts simply didn’t want to be left out of the fun whenever that happened. While the milk she disgorged during a proper boobgasm was far beyond anything another mare could dream of, it was a pittance next to Derpy’s actual capabilities, so there could hardly be any point to it but pleasure.
Fortunately, the knowledge that her family certainly did not need a demonstration of what Derpy’s rack was capable of and that the bigger mare was nearly impossible to fluster through lewd displays alone had made it easier than usual for Derpy to keep her cool. Besides, Derpy intended to grow larger. Her boobs would get in the way a lot more in coming years. It was obviously a practical necessity that their daughters grew up regarding it as normal to touch Derpy's breasts for purely pragmatic reasons. That wouldn't work if they assumed that any touch would drive Derpy wild. It would be far too awkward and uncomfortable.
Berry stepped up and with a few deft, practiced motions stuffed Derpy's tits into the top. Her large nipples required particular effort, to Derpy's delight. Berry snorted in pretended exasperation. "Y'know, this is just another one of your jugs' nonsense powers, yeah?"
"Hm?" Just because the presence of her family made it easier to keep her cool while being roughly handled didn't make it precisely trivial. She felt the heat mounting. Fortunately, as her breasts had grown to provide ever more pleasure, Derpy had become more accustomed to functioning normally at higher levels of arousal. The heights were higher, but the way there could be enjoyed covertly, for the most part.
"That it didn't hurt or make you uncomfortable." Berry gestured at Derpy's rack and the top barely containing it.
She was bulging out obscenely at the top, bottom and even the sides by her arms. The garment entirely failed to hide her plump nipples and her broad, pebbly aureola. Derpy experienced a giddy kind of anticipation at the thought of bursting out of its feeble grasp eventually. Her plenitude could only be held back as long as she allowed it. Of course they didn't hurt. Her breasts were something beyond normal pony understanding, miracles of fertility which preceded her wherever she went. It would take a lot more than an undersized top to make them hurt. She gave them a little bounce. Seams creaked in warning, to her distinct pleasure.
Derpy made a deliberate effort not to think further along those lines. "Pain really isn't the pressing problem when you treat 'em like that." She smiled. "Anyway, let's go, everyone."
Derpy had initially been a little disappointed by the local Barnyard Bargains. The aisles were spaced very generously and she would have to grow much, much larger breasts to start seriously inconveniencing other shoppers.
It was going to have to be a life goals thing. She wasn’t going to raise her kids forever, it was good to have dreams.
She didn’t otherwise mind the store. Some of the locals had made noises that the produce wasn’t as good as when it was bought on the market, which might have been true, but it was also a pretty typical complaint for sheltered heartlanders. Derpy and Berry had been adventurous enough in their younger years to simply appreciate that food was available in abundance. You couldn’t take that for granted just anywhere.
Of course, abundance had become one of Derpy’s defining traits as well. Or possibly the defining trait of her two defining traits. Although most of it had just been Derpy messing with people, she had most of Ponyville convinced that she simply couldn’t help uncontrollably erupting with milk every now and then, such was the fecundity of her great glands.
It wasn’t true, really. Derpy was usually in full control, or at least knew how to get her boobs calmed back down. If anything was out of control, it might have been her growing tendency towards exhibitionism. It was simply too delightful to have her size and productivity on display. That was, after all, why she was wearing the undersized tank top she had selected.
This was meant to be a family shopping trip however, so Derpy was on her best behavior. Or in any case, moderately good behavior. Sufficiently prudish ponies might think that the best behavior for someone as stacked as Derpy would be to stay out of the public eye.
That wouldn’t do, of course. It’d be a crime to hide her boobs away, especially now that they were large enough to be truly memorable. Every furtively stolen glance seemed to brush across her skin like feathers, sending a shiver of delight from her nipples to her loins, as though Derpy was experiencing a forbidden thrill by proxy.
Of course there was nothing actually forbidden about it. Those ponies who knew Derpy even a little took their time to admire her size before going on with their day. She responded with indulgent smiles and a deep sense of satisfaction. Her boobs did deserve more than a cursory glance, after all. One day she’d be big enough to leave jaws dropped in awe in her wake wherever she went. She still pretended to be surprised that the walk to the store had already escalated her persistent lust to dangerously fun heights.
Still, their daughters walked confidently now, so they tended to grab from the shelves whatever sparked their interest, so Derpy couldn’t just spend the whole trip suggestively stretching her back or fussing with the straps of her top to make her boobs shift ponderously for the audience.
“Put that back, Pinchy, we got plenty of candy at home.”
“Please?”
Berry, leaning on the shopping cart, cut in sternly. “Listen to mom, kid. We’ll have some chocolate at home if you behave.”
Derpy had been distracted keeping an eye on Dinky when Berry clapped a hand on her shoulder.
“That girl’s new in town,” the earth pony whispered, minutely inclining her head towards the dairy section.
That wasn’t one hundred percent certain to be true, but Derpy judged it pretty likely. As a mailmare she knew a lot of people, and ever since Pinkie Pie had moved in with the Cakes, newcomers tended to be greeted very publicly.
Derpy just turned and looked. Subtlety was for other people. The mare in question looked like a much skinnier, pegasus version of Carrot Top, wearing the store’s uniform and standing by something like a cocktail table full of bits of cheese on toothpicks. Occasionally one of her wings twitched in the draft of the store’s ventilation. Wearing a plastic smile, she offered samples to passing customers. Derpy guessed that the job wasn’t very close to the mare’s special talent.
“Why don’t I finish shopping and you see if she’s open to some fun, yeah?” Unsaid went, of course, that Berry would have to wrangle both kids on her own in that case.
“You sure? She’ll probably be here all day, no special hurry.”
“I’m sure. Maybe she’ll teach you something new about dairy. And the longer you wait, the higher the chance someone will tell her about you.” Berry smirked. “Town’s not got much else going for it but that one mailmare with the fantastic … uh … assets,” she finished lamely with a quick glance towards their daughters.
Derpy bit her lip. The lure of untapped potential was great. Out of the corner of her eye she saw refrigerated shelves full of cheese. “Alright. I’ll make it up to you later.”
“You always do,” Berry nodded agreeably before turning her attention to the task of explaining to their girls that Derpy had to talk to another grown-up and would stay behind.
Berry Punch was an able and willing sexual partner, but the mare would be just as happy, if not more so, with family snuggling time instead of anything carnal. Although there were parties who saw the earth pony as little more than a brass knuckle in a shirt, Derpy was sure that the emotional intimacy of their relationship was what Berry valued most.
Derpy valued that as well. Her amazing breasts were meant to be shared, but Derpy herself belonged to Berry even as she allowed others to worship at the altar of her rack to aid in her growth. That the emergence of her peculiar powers had done nearly nothing to change their long relationship was constant cause for gratitude in Derpy’s heart.
And even so the silly earth pony probably mentally celebrated being left alone with their daughters as some notable sign of trust, as though she wasn’t the most reliable pony Derpy knew. As though Derpy wasted any thoughts deliberating, doubting. She’d sooner doubt her own wings. Derpy could hardly allow herself to go around seducing, teasing and generally making a nuisance of herself if she didn’t have someone so rock solid in her corner.
Sadly, while her breasts had the most amusing effects on many ponies, they did nothing to help Derpy make her best friend see herself in the same light as the pegasus and their daughters did.
Those were thoughts for another time, however. Derpy turned and meandered past the unknown mare and her table a few times, making an act of inspecting the inventory while allowing some of her milk to seep out and begin forming obvious wet spots on her top.
“Excuse me? Maybe a sample would help you make a choice?” There was no real enthusiasm to the offer, the mare had probably figured that she should take pity on a particularly indecisive customer.
Derpy turned quickly as if startled, straightening a little to thrust out her chest as it wobbled from the turn’s momentum as much as the top would permit. The pop of a tortured seam sounded loudly in the sudden silence of the other mare’s awkward stare.
Pretending to bashfully adjust her top while succeeding only in making herself bulge out of it elsewhere more notably, Derpy nodded. “Woo, you startled me! But sure, I’ll take you up on that.”
The samples of cheese were arranged on a round tray which the other mare wordlessly pushed slightly towards Derpy before averting her eyes. Eventually, she spoke up again. “It’s, uh, a sour milk cheese. Very low fat, high protein.”
Had a strong smell and powerful flavor as well. Derpy chewed thoughtfully, suspecting that it was a divisive taste. “It’s good!” She lightly pushed the tray away from herself, crossed her arms under her breasts and heaved her bosom onto the table as though it was some great feat of strength.
“Uh…”
“I’m sorry, I’ve just got to take a load off for a few minutes.” Derpy smiled warmly, using one hand to pat the side of a breast fondly. “Don’t worry, everypony knows me. I won’t scare anyone off.”
Although she was acutely aware of their considerable weight, Derpy didn’t find her breasts particularly burdensome, another detail Berry had noted with a sort of amused exasperation. Everything came up tits in Derpy’s life.
“Sure,” the other mare replied uncertainly, trying hard not to look at Derpy’s boobs while vaguely gesturing towards the wet spots over her prominent nipples. “Are you … are you having some kind of emergency?”
Derpy reached for her stiffening nubs, acting like she didn’t know exactly what was going on. She released a little more milk, allowing the stains to spread as she pulled her hands back and tried to titter coyly. “Oh, that. It’s nothing to worry about, happens all the time.” Mostly, of course, because Derpy enjoyed the reactions to it.
“Okay?” The response sounded dubious. “Can’t you just, you know, drain them before …” The mare trailed off, blushing. Perhaps she was regretting the impulse to discuss another mare’s lactation in the current setting.
“Oh no,” Derpy responded in a tone of fond amusement. “Paying that kind of attention just makes everything worse.” She shook her head. “They haven’t invented the pump that can keep up with these two once once I let them off the leash.”
Her great glands gurgled noisily, communicating their agreement. Derpy patted one of them soothingly while the other pony seemed startled. A passing customer quickened his step seemingly at random.
“I don’t know how to respond to that,” the other mare eventually stated, appearing concerned for reasons beyond Derpy’s grasp.
“That’s okay! Why don’t you tell me about cheese instead?” It was not yet time to more fully introduce the other pony to the gorgeous mysteries that were Derpy’s breasts. “How hard is it to make your own cheese, anyway?”
“Easier than most ponies think,” the mare stated. “City ponies, anyway. I expect a lot of folks around here have some notion of it or know somepony who does.” She did not mention that most pegasi wouldn’t know what to do with a cow, either. Sticking out her hand, she introduced herself. “I’m Gale Delight. My family makes and sells cheese. Mr. Rich is adding more of our product to his selection.”
Derpy shook her hand. “Derpy Hooves. I’m not looking to go pro or anything, I’m just wondering if it’s something suitable to do with my kids. Not in school yet.”
“Small batches at home? Absolutely.” The other pegasus smiled. “The results get better with experimentation and experience, that’s a good lesson to learn, too.”
She went on to talk about bacterial starter cultures, whether to buy them or to start one from spoiled milk, useful equipment and other details with enough enthusiasm to suggest that her special talent was probably closely related.
Derpy listened patiently, always delighted to see another pony take joy in a topic dear to them. She only interjected with minor questions and sometimes shifted her position to allow a passing customer to swipe a sample of cheese.
She could not help her amused smile when Miss Delight explained how important it was to know about the animals sourcing the milk and what they were being fed when aiming for particular flavors of cheese. Any Ponyville native would have made the correct assumptions by now.
It was almost regrettable that certain trains of thought were difficult to stop at that point. Although Derpy did not expect that making her own cheese would induce the same sense of wholesome contentment as actually nursing a pony did, being able to replace cow’s milk in more applications at home than just for drinking and baking promised considerable satisfaction. It was an additional way to share her wealth with other ponies.
Her breasts throbbed enthusiastically as Derpy considering selling home-made cheese on market days. As her eyes wandered over the offerings on the shelves, she adjusted her ambitions accordingly. Who needed cows? Sooner or later Derpy would produce enough milk to supply every dairy product stocked here, then enough to supply every Barnyard Bargains across the nation.
Encouraged by such fantasies, her milk factories seemed to respond by shifting into a higher gear. Her constant, unceasing production formed the background noise to Derpy’s life, she felt it when she drifted off to sleep and was greeted by it every morning. The frantic churning sensation now commencing at the core of her breasts made Derpy stifle a whimper.
Indescribable pleasure inexorably spread from her erect nipples like an encroaching tide. A less experienced mare might already have collapsed in helpless climax. Derpy endured, for now, although she knew that her time was limited as she felt her breasts grow tight and engorged, struggling against her torturously tight top, internal pressure aiming to firm them up into proud globes.
There was a groan, Derpy wasn’t sure if it had been her own or some noise of determination produced by her eager tits.
“Are … are you alright?”
Derpy, flushed with arousal, stood up straighter. “I’m sorry about this. Thoughts ran away with me.” Her tank top could no longer constrain a pair of breasts unwilling to be squished and deformed by outside forces. Seams snapped, great tears opened up in the fabric, allowing flesh to press through and exposing her throbbing nipples to the air. Derpy could imagine them reaching out desperately to the other mare’s waiting mouth.
Being too big for the garment further compounded Derpy’s arousal. It was just a taste of the future. One day she would be entirely beyond containment, unchecked by a world in silent awe of her vastness and productivity. She turned away from the other mare, since pointing her boobs away from her uniform and the innocent cheese on the table had the positive consequence of exposing her proud breasts and the mortally wounded top clinging to them to a wider audience.
Thin streams of milk squirted from her, as though individual ducts were managing to slip from her control for brief moments. While Derpy remained broadly aware of herself, the only ways to stop being constantly bombarded with ecstasy and restore normal functioning would be a mindblowing orgasm including a spectacular eruption of milk, or, less messily, breastfeeding a willing pony. Always sufficiently soothing to prevent Mt. Derpy from erupting.
Really, it was only fair. If Derpy was going to get her breasts this fired up, it was only right that she appease them either by making a ridiculously memorable spectacle of them or by putting them to the use they were intended for.
Derpy was still imagining her tits as twin volcanoes, rumblingly threatening unfortunate local civilizations with a milky apocalypse when the other mare deftly grabbed her by the shoulders and frogmarched her away and into the employee break room. The sudden loss of audience pained her, but Derpy resolved to be a patient volcano goddess. Perhaps Gale Delight could win back her favor before the local culture was washed away in a deluge of cream.
“Do you need medical attention?” The note of concern in her voice was touching, if a little confusing.
“N-no,” Derpy replied, leaning against a row of lockers. Milk ran freely from her fat nipples, forming brief rivulets before running into the ruins of her top. Not enough to prevent the oncoming disaster, but sufficient to serve as a warning.
“You’re clearly in some distress.” The other mare gestured helplessly towards Derpy’s chest. “That looks painful, you’re sweating and not breathing regularly.”
“I am hornier than you can possibly imagine,” Derpy stated slowly and clearly. The room wasn’t nearly as well ventilated as the store itself, the smell of milk was quite obvious and getting more pervasive. With slow deliberation, she raised one hand to her breast. She tensed her fingers, failing utterly to grab a handful of her unyielding flesh. Frustrating. Only Berry had the grip strength to work her tits properly in this state, and only Berry actually trusted that Derpy’s mighty bosom could take it. Other ponies Derpy had seduced had tended to chicken out. “Two ways out of this.”
“Two?”
“Two.” Derpy really should have planned better than to get this worked up before she’d even gotten the girl interested. There was no way for her jugs to get any more firm and round, instead they seemed to get heavier, as the milk being prepared for release was being packed more and more densely. Despite the tightness of her skin, they still sagged slightly more than before, as though to pull her forward. If Derpy tripped and fell onto her tits, she’d be a lost cause immediately. She moaned sloppily, her other hand darting to her nipples to start tweaking them, desperate to increase the steady, insufficient flow of her payload. Her moan turned into a groan of frustration. Now, now her boobs were being stubborn. No additional relief until the main event. “I stop holding back.” She took a steadying breath. “Trust me. Clean-up would be nightmarish.”
Derpy was reduced to writhing against the wall by a particularly intense spike of pleasure caused by the truth of her statement. The shocks of bliss she was experiencing were stirring up her incomprehensible resources, the normally calm and reassuring ocean of milk at the edge of Derpy’s awareness turning into a devastating tidal wave of pleasure seeking release. “F-fuck.”
“The second option?” Almost desperate hope tinged the question. Clearly the mare didn’t want to be responsible for a gigantic milky mess.
“Come here. Drink from me. Willingly.” Derpy smiled. “It’s harmless. Never hurt anyone nursing from me.”
A doubtful look. “Really? That’s it?”
“Got a doctor’s note.” The events of that delightful day had been memorable, but those memories weren’t suited to improving Derpy’s composure.
“Ugh, fine. Better than the clean-up,” the mare eventually shrugged.
Derpy held up her hand. “Has to be willing, for you.”
“I can’t just be okay with sucking on your tit on command!”
Reasonable, if inconvenient. Some negotiation was not unprecedented, although usually Derpy had things together at that point in the proceedings. “Why were you….hff...unhappy at your job?”
“Is this really the time?”
“Humor me.” Derpy managed a smirk, slowly sitting down on a low bench. In this state, even sitting made her dream about the day when her rack would finally overflow her lap in every direction. “Can put the kids to bed in this state. Berry … Berry has to do the lullabies, then.”
“I got a degree in business administration, and I really care about cheese, yet my family expects me to hand out samples! It’s a done deal that Dairy Delights gets handed to my siblings once my parents retire.”
Maybe Derpy’s seeming vulnerability in this moment made it easier for Gale to let her complaints spill forth. “Go on. I’m listening.” Some effort was required to sound patient.
“I’m a lot younger than the others,” Gale explained. “I’m the only one who isn’t an earth pony. Apparently that wasn’t good for my parents’ marriage.”
Some people still got like that, unwilling to believe that it was unlikely that their family had remained entirely pure in all that time since the unification.
“I’m the only one without a dairy name. Probably expected me to run off and join a weather team or something.” Gale threw up her hands, pacing. “And don’t get me started on that cloud city full of insufferable jocks! I do cheese caves. Humidity and temperature has to be just right for the best cave aged cheese, okay?! It’s not a joke, it’s an ancient craft!”
“Preach it. Never fit in Cloudsdale either.” Derpy suspected that some would be more incredulous about a fellow pegasus having any talent revolving around caves, rather than the dairy thing specifically. “Unicorn daughter. Love her to bits.” She wanted very badly to give the other mare a comforting hug and then gently nurse her. Unfortunately, the promise of it did nothing to calm her wildly firing nerves still keeping her mind fuzzy with pleasure. In her imagination, she’d already relinquished control and flooded the room with her twin geysirs.
“My parents are never gonna be proud of me,” Gale concluded morosely. “The best I’ll get is my brothers and sisters humoring me. Maybe they’ll give me a real stake once our parents are dead.” She did not point out that elderly earth ponies sometimes hung on for a long time.
Her breasts pulsed impatiently, but there were more important things than giving in to animal pleasure. “Gotta be honest with you. If was going to try making cheese from my own milk. Fantasizing about feeding people ...it sets me off.”
The sequence of expressions on the other pony’s face went from a brief moment of revulsion over resignation to sudden defiance. “Ew. But you know what? That’s still a better use of my time and skills than standing there handing out samples. I’m doing an entirely menial job just so I can say I’m working for the family business. I have no pride. Fuck!”
Derpy indicated a spot next to her. “Sit.”
Gale moved to obey with a sigh. “I’m also really jealous of your looks despite your, uh, your thing with the milk. I think growing up around all those earth pony body types gave me body issues or something.”
Although it seemed callous, that was at least some kind of leverage. “Could help with that. Some people drinking from me … they get small gifts. Always something they’re happy with.” She paused. Both ponies in the room regarded Derpy’s boobs meaningfully. “Always harmless so far. Nothing like mine.”
“Huh. You raid some ancient temple and make off with a cursed, or possibly blessed, fertility idol?” The mare’s resistance to the idea was clearly evaporating rapidly.
“Would explain things. There is no explanation so far.” Derpy grinned broadly and tweaked her nipples some more, still flying high on waves of euphoria. If she didn’t expect her legs to just spasmodically collapse from under her, she’d be tempted to just keep skirting the edge and see how long she could ride this out as she went about her day. Flying seemed right out in this state of mind. She’d probably plow through a wall and then have a screaming orgasm about it. She was already sopping wet. “Fertility doesn’t fit. Have enough kids personally. I’m a volcano goddess. You gonna sacrifice yourself to … to prevent the twin peaks from erupting? Would make up for taking me away from my native attendants outside.”
Gale seemed amused. “Do you really want to have your breasts associated with natural disasters?” She’d probably meant it to poke fun, at that.
“Celestia, YES,” Derpy moaned an affirmation. That awful, beautiful, churning at the core of her awesome tits redoubled. There were other sensations, she was unable to tell if they were sounds or particularly intrusive physical perceptions. “I want to be huge and inconvenient,” she declared, grabbing her chest and giving it a slow jostle. She was rewarded with sloshing, promising a great and terrible flood. “Something other ponies have to just put up with, adjust their lives around or flee as far as they can.” Her drum-tight skin groaned, just another meaningless token protest, just as unable as any others to stop her imagined transformation into an Equestrian landmark. “I wanna make the national news,” she gasped. “‘Mailmare paints town White,’ or maybe ‘Badlands turned wetlands, scientists observe new biome’.” Her glands gurgled, eager to warp entire ecologies at Derpy’s command. “‘Everfree washed away, disaster or blessing in disguise?’”
Distantly, Derpy noted the growing concern with which her audience of one had listened to her. Or to her breasts? Seemed unimportant. She was feeling uncomfortably enclosed by the locker room. Derpy struggled to remember why she allowed fragile pony structures to pretend at containing her. With a bit of effort she could probably generate enough pressure to cut through the roof of this petty shack.
She was eager to put that theory to the test when Derpy felt a set of warm lips hesitantly seal around one of her leaking nipples. The let-down reflex was immediate, but gentle. Even while fantasizing about her future as divine cause of ecological upheaval on a massive, ideally even global, scale, she’d never harm any who came to her looking for nourishment.
Gale knelt awkwardly in front of her, looking up at Derpy, eyes full of uncertainty. It caused her a pang of shame. Not so much for losing control, that was ultimately harmless. She should never even have wondered why she only indulged herself in moderation. The most important ponies in the world relied on her for so much more than mere food. She was a mother and a lover. Growing into a giant headache for the town or even the country could wait until the kids were out of the house.
Derpy gently rubbed her breasts, now beginning to feel more pliable again. “I like to see how long I can stay lucid before defusing the situation. Need to reinforce that I’m in charge before these ladies are bigger than the rest of me.” She clucked her tongue. “It’s fun to make a splash, and catching ponies unawares if great, but fantasizing about it to get myself off is kinda self-defeating.” Maybe it was some kind of strange safety feature that the activity which actually made her beautiful breasts grow larger and more productive was soothing rather than arousing. Made it easy to trust in the ultimate benevolence of her boobs.
Gale’s inexplicable confusion regarding Derpy’s self-evidently sensible explanation was suddenly replaced with wide-eyes surprise as she began suckling more and more urgently.
“It’s starting, I can feel it, too.” There was a strange connection Derpy felt with those who drank from her. They didn’t seem particularly more likely to like her, but Derpy looked at such ponies and felt certain that they were hers. Maybe her boobs had an internal list of customers served, useful since Derpy only benefited from the first time she fed any one pony. Since other ponies consistently failed to experience any kind of epiphany at those times, that explanation seemed most applicable.
She cradled Gale’s head as the other mare began moaning into her breasts between gulps. The other pegasus struggled to maintain her position as she twitched, so Derpy slid off the bench to sit on the floor, where Gale could stretch out and lay her head in Derpy’s lab. With the great breasts no longer so terribly firm, it was a workable arrangement.
Dreams of expansion forgotten for the moment, Derpy allowed the soothing feeling of providing for another pony to wash over her. Her own changes were waiting in the wings, although they often seemed to lay in wait until the other pony was fit to watch it happen.
Gale was arching her back from the pleasure of the change. Her hips widened, straining the uniform, her formerly modest breasts were starting to test the limits of her shirt. Her final orgasmic cry was muffled by Derpy’s breastflesh as the other pegasus grabbed her uniform and tore it off herself with previously unseen strength. Finally letting go of Derpy’s nipple, Gale panted. “Celestia, that was delicious.”
Derpy watched the other mare stand, unguardedly appreciating her new body. Gale seemed just over six feet tall, she probably weighed something like 200 pounds now, very well spread and proportioned. Her tits were well beyond bras off the rack, although nowhere near the size of Derpy’s. Still, outside of Ponyville, the mare would certainly provide other ponies the kind of encounters they would tell their friends about. ‘Mate, I saw this pegasus with jugs out to here!’. They seemed to defy gravity to maintain a pleasant shape without support much in the way Derpy’s did and generally contributed to an attractive hourglass shape supported by a fantastic ass. Her stomach wasn’t quite flat, and her hips and thighs looked like they could squeeze a pony in two with only moderate effort.
“Are you okay, Gale? That’s the most anyone’s ever changed, and … I like tall mares, not sure if that’s my fault. Or that ass.” Almost as good as Berry’s, she didn’t say.
“Absolutely, this is excellent.” She cupped her own breasts and jiggled them playfully. “No milk. No offense, but I don’t think I’ll personally experimenting with pony cheese.”
“That’s fine. Now please watch me.” Derpy’s breasts probably didn’t really grow all that much. It tended to vary slightly and in any case the growth was always added to an increasingly larger total. Nonetheless, the tattered rags still clinging to Derpy finally let go, some falling forlornly off her body while other bits, soaked with milk, continued to cling to her. Her boobs felt pleasantly warm, now appeased and eager to serve, rather than engorged and demanding.
Much to her surprise, she felt her hips widen considerably, although not matching Gale’s. The new sensation was not painful but certainly unexpected, she'd almost given up hope that she'd ever grow that way, despite a feeling she'd been having the first time she shared her milk with Berry. Her rear grew to match as she stood, her low-effort sweatpants beginning to look enticingly tight on her lower half. “I’d been thinking that a bit of counterweight might look nice, as long as I stay top heavy.” She smirked at Gale. “Might not blow my socks off like it did for you, but it adds to the total every time.”
Someone cleared their throat. “One of the unused lockers should have a stallion-sized uniform that should fit, Miss Delight,” Mr. Rich stated mildly.
“Oh shit, I’m sorry, Mr. Rich!” Gale whirled to face the guy without apparent shame regarding her nudity.
“Nothing to be sorry for,” he claimed, very studiously not looking at any naked breasts in the room. “Miss Hooves is by now a known quantity and by all accounts your quick action prevented a more public mess in my store. Your family will only hear praise from me.”
He turned roughly in Derpy’s direction, gazing intently at a spot on the wall somewhere above her head. “Miss Hooves.” It somehow managed to be more sigh than address. “I consider your eccentricity to be a charming bit of local color. However, I have no doubt that word of this, however distorted, will eventually reach my wife, and she will renew her demands to ban you from my stores.”
Spoiled Rich was an awful shrew entirely undeserving of anyone’s loyalty. Derpy shrugged. “No hard feelings, sir, but the lady really doesn’t give you enough credit. I wouldn’t even need my whole hand to count the stallions still trying not to stare.” She encouraged it, but it didn’t mean that she couldn’t give credit for good efforts.
Mr. Rich huffed, somehow not unkindly. “Not everyone recognizes the nobility in a doomed struggle,” he commented dryly. “A good day to you both.”
“Wow, they really know you around here,” Gale observed as she put on a new uniform. “Didn’t even offer to let you cover up with something from the store.”
“Out the back door and upwards, it’s not public nudity if you’re high enough above street level.” Derpy collected the sad remnants of her top. “This one lasted way longer than any others of that size, I’m tempted to frame it and put it up in the bedroom.”
Gale gestured at their new forms. “I dunno, this seems souvenir enough.”
“Yeah, but that’s the new you from now on.” Derpy grinned, pointing her thumbs at her own boobs. “These ladies have never been this big, but they’ll never be this small again. I need something more tangible for a keepsake.” She shook her head. “Anyway, take care.”
“Wait, you’re just going to leave?” Gale sounded surprised, perhaps a little upset.
“Sure? We both came out ahead today, I think.” Derpy was experiencing an entirely more placid emotional high than just minutes ago. Her new flesh always seemed particularly alive with sensation after new growth, as though the added mass of glands was dutifully signaling that it was eager to add to her endless bounty.
Derpy did a little twirl in the middle of the room, snapping out her wings to keep her balance as she felt the familiar bounce and jiggle of her bosom, but also, wondrously, something similar from her enlarged butt. Additionally, her wider hips, probably still modest in a town full of earth ponies, felt huge to the once lithe pegasus. She sighed in satisfaction, as no doubt Berry would do her the favor of exploring Derpy’s new dimensions. With a shrug, she made for the back door.
Gale followed her out and immediately made a grab for Derpy, firmly redirecting her in a direction that would lead around the building to the much more public space in front of the store. “I don’t think we’re done yet. Sure, I look amazing now, but that’s just a side-effect to what you wanted. You were just messing with me out in the store, and I think I deserve a little payback.”
Derpy had no problem with their direction, or being seen topless in public. Quite the opposite. And with the remains of her old garment in hand, she carried proof that she hadn’t intended to be indecent, a medical emergency had put her in that position. Obviously. Frankly, most of Ponyville took her in stride by now. “If you wanted sex you could have just said so.”
“I want to see some evidence,” Gale declared.
The calm contentment Derpy had been enjoying was blown out like a candle. She stopped in place. “What?” Warning tingles made themselves known deep within her endowments.
Gale faced her with a hungry smile. “You talked a good game in there, and you certainly looked pent up, but all I saw was a little squirting, a little dripping.” She leaned closer. “I made my choice, but did you trick me into it?”
A reasonable request, Derpy agreed intellectually. Certainly the mare didn’t need that new bit of doubt in her life. She would have been glad to demonstrate somewhere secluded. Unfortunately, all her tits heard was that someone who’d already been blessed by them still doubted their capabilities. Derpy’s nipples twitched, milk started running down the slopes of her boobs to drip to the ground or soak into her pants. “And this needs to happen in public?” She tried not to sound eager.
Gale scoffed. “What if Mr. Rich and everyone else is just humoring your wild fantasies? Just the crazy tit lady. They’re probably glad you know how to put on pants.”
No. No! Derpy’s neighbors did humor and indulge her, but they never doubted her capabilities. Her boobs slowly grew firmer once more, apparently of the opinion that a reminder wouldn’t hurt. Besides, Gale was likely just trying to rile her up, as though Derpy couldn’t do better herself.
And do better she would. Derpy raised her hands to the sides of her boobs and fiercely grabbed a handful of flesh each, not without effort. She’d equated her astounding tits with natural disasters which might be averted by appeasing the relevant goddess. But Derpy had been merciful and patient, struggling to control herself even before it was certain that she would receive her due.
The pleasure of her own rough handling drew a moan from Derpy and she leaned against the wall. “Ladies,” she tightened her grip, shivering. She’d need something extraordinary, out of proportion even with Derpy’s size. Something that would mark witnesses forever. Every moment not given to conscious thought should bring her mind wandering back to Derpy’s breasts and their milk.
“Are you about to start masturbating? Is this happening?” Gale’s earlier fierceness seemed brittle.
Derpy’s proud breasts were eager, so eager to put this girl in her place. Already the current, pitiful flow of milk turned into forceful spurts, arcing all the way across the narrow alley behind the store.
If only ponies could know what Derpy saw in her future. They looked at the mailmare, the huge, brazen tits she flaunted, and assumed she’d peak sooner rather than later. Perhaps they thought she was some unlikely aberration, more cow than mare. They thought so small. Even Gale, who’d been gifted a beautiful transformation, wouldn’t allow herself to believe fully. Why couldn't they be like Berry, who apparently just assumed that Derpy would never stop growing, would be immortal just to have more time to grow?
On lazy afternoons when their daughters were napping, curled up against Derpy while she leaned against a lightly dozing Berry, Derpy would listen to the industrious hum of her glands, audible only to herself. In quiet moments like these, she knew the truth of it: That there would always be more of her, more, beyond her current ability to grasp. That there would never be a time when her family had to face a world with less of her love, her breasts and her milk in it. Perhaps Berry had it right and Derpy simply had never thought of it.
She tried to imagine herself ten years down the line. Her breasts each three, maybe four feet across, her upper body, probably her hips, entirely obscured by the largest milk factories in the world. Every time she landed on her mail route, her uniform would struggle to contain the ponderous bounce and jiggle of her vastness. Her nipples might be as big as her fists or more, capable of dispensing truly absurd amounts of milk every second.
Maybe one day the mere presence of her obscene glands, their sheer, monstrous fecundity, would change the world around her, young mares having six, eight, even ten foals at a time, all would grow strong from Derpy’s milk, a population explosion sustained by her tremendous tits, each generation more fruitful than the last, spreading across the world as heralds of her expansion and the promise that one day, no creature on this world would ever go hungry again.
She’d barely stuck her hand down her pants to finger her sopping slit before she came with a moan, her wings snapping out before they joined in on stimulating her bosom with the tips of her feathers.
They were beautiful fantasies of a future yet out of reach, but today, as small and limited as she still was, Derpy wanted to achieve something Ponyville would remember years from now, no matter her growth in that time. Her nipples were achingly hard, her breasts impossibly firm.
For once, Derpy was not playfully struggling to hold back the release of her milk until a moment of her choosing, she was demanding the best her breasts could provide, the most her body could withstand. She started sweating profusely as her rack grew uncomfortable warm.
The previous churning returned, louder, more forcefully, almost growling. Derpy was dimly aware that the other mare took a step away. Her broad areolas seemed to bulge outward slightly, while her skin creaked and groaned, tasked with containing a catastrophic deluge. Her overburdened jugs started to pulse bigger, however briefly, before returning to their previous size. A dull ache made itself known within her breasts and Derpy got the most peculiar feeling that they were pressing down on themselves, struggling to prepare ever more milk for dispersal in the same space. They grew perceptibly heavier.
“Always holding back,” she mumbled, breathing heavily. “Raising the kids ...is more important. But today …hfff... today’s gonna be good enough ...nng… for a creation myth.”
“What does that even mean??”
People need a glimpse of the future.
Despite the mounting discomfort, Derpy came again as before her eyes, her breasts bulged larger, not the usual smooth growth, but in fits and starts. There was none of the wholesome sense of rightness she’d come to associate with the growth of her flesh and the glands within that came as a reward for feeding ponies, just overwhelming pressure as her body was forced to expand from within, more and more of the milk she normally called on from parts unknown being forced into her physical form. What little release provided by the fluid leaking and spurting from her currently was meaningless in the face of it.
“It’s time,” Derpy declared, stumbling forward even as her great rack continued to creep larger against the protests of her strained body. The world seemed to recede from her, all that mattered was the aching need for release, and the knowledge that she'd never output enough to keep pace with her production.
Emerging onto the square in front of the Barnyard Bargains caused the eyes of every passing pony to zero in on her glorious, naked breasts, the effect rippling outward like a wave. The immense pleasure of having so large an audience caused her another climax, she missed a step, staggered, kept walking.
“Are you alright, dear?”
Derpy had been just about to open the floodgates for good, but the blue cupcake mare was kind, she gave her stallion proper credit for not openly staring at the mailmare’s astounding rack and forgave him when he faltered without resenting Derpy. She deserved consideration.
She sort of vaguely gestured behind her. “There’s … an unbeliever,” she explained, aggrieved.
The other mare looked Derpy’s current company over, brow furrowed in confusion for several moments before she understood. “You’ll just have to make Ponyville proud, then.” Her expression fell immediately, maybe she hadn’t wanted to admit that their hometown had little to distinguish it except for anxiety about Everfree monsters and Derpy’s intimidating boobs, unless one happened to be obsessed with apples. The blue mare strode off briskly towards the store. Derpy chose to allow this.
Ponies were staring, some more openly than others, but they weren’t yet gawping in helpless awe. Derpy finally allowed herself release, the thin, irregular squirts of her milk uniting into two mighty torrents. She was rocked by another climax before frowning briefly. Her range was too short, the unnatural weight of her breasts forcing her fat nipples to point downwards. Her milk frothed and churned in an expanding puddle a few feet in front of her. She doubted any other creature in the region could gush so forcefully, but she resolved to do better, using both of her arms to hold up her bosom, her output arcing away into the distance.
It was a tiring pose, and the twin pleasures of sweet release and a large audience flooded her mind with unparalleled bliss. Derpy laughed, was interrupted by her own sloppy moans, laughed again. She allowed her breasts to fall, they were still too taut to properly slap down against her stomach, instead nearly toppling her forward.
Ponies whispered and talked, indistinct, irrelevant. Delirious with sheer ecstasy, Derpy wandered this way and that, mashing her tits together, tweaking her nipples, demanding more of her breasts. Her output escalated, and Derpy felt she should compensate by leaning forward as though walking into a headwind.
She fell forward, braced herself on arms numb and uncoordinated from the sensations washing the edges and distinctions off her thoughts, then landed on her tits, still so damnably tight. It should have hurt, it might at some unimportant future point, but everything was pleasure now. She felt herself continue to grow and came again, crying out from the awesome feeling of her grotesque output redoubling again and again and again.
She spent a few moments at the center of a growing white puddle before struggling to get up. She slapped her palms against her expanding jugs, still gushing without end, pausing only to spend a few seconds to think fondly of Berry, who knew her breasts so well. She experienced a pang of regret on noticing that the ponies around her were keeping their distance. She tried to grab handfuls of her terrifyingly productive titflesh, but it barely yielded under her fingers. The sensation of weight was tremendous, but the main reason Derpy had to use her wings to assist in dragging herself to her feet was how huge and bloated her rack was, she couldn't squeeze them together between her arms to support herself on them.
I'm built to have huge tits.
Derpy was certain that her current size, the girth of her tits nearly twice what it had been that morning, would be temporary, an escalation of fullness and engorgement. Additionally, Berry Punch preferred the normal feel of her breasts when they weren't so stuffed and eager for release. She couldn't quite see how those two facts connected, but they were important.
Just as Derpy was about get solid footing to wander off again, she heard it. Barely capable of coherent thought in her current state, she couldn’t make out what the ponies around her were saying. But there were the first strains of reverence in the murmurs, the first notes of dawning understanding.
Derpy collapsed into a heap, splashing back down into a growing lake of milk and rolled onto her back, moaning lewdly. She kneaded her boobs fiercely as they sprayed, milk raining back down on her. "I'm still full!" She called out in a moment of lucidity, giggling at the absurdity of the situation. "Do you get it? T-tonight ... hff ... I'll have more milk than this morning!" Her back arched as she came again. In that moment, she wanted Berry to be right. She wanted to live forever, to make her endless milk available to everypony's children and grandchildren. To experience pleasure like this whenever she cared to. She wanted whole generations to grow up taking her milk entirely for granted.
The last vestiges of her awareness were washed away in white pleasure exploding from her abused nipples and arcing through her body like lightning as Derpy realized that her current audience understood. Ponyville needed never to fear hunger again. Droughts, ruined harvests, harsh winters all rendered irrelevant by her limitless resources.
-------------
Derpy’s next clear impression was the sound of Berry Punch’s voice and a large, yet gentle hand on her shoulder. She found herself sitting on the rim of the basin below the statue of a rearing earth pony, facing inward and milking herself into the water in great, irregular spurts as she tugged lazily at her nipples. She’d been staring into her own cleavage, now again roughly the size she’d earned in the back room of Barnyard Bargains, and contemplated her superlative abundance. Derpy did tend to lose track of time, doing that.
“Time to get you home, Derps,” Berry suggested kindly. “I think your latest conquest left, probably didn’t wanna get drafted to clean up milk above earth pony reach.” She carried a large towel slung over her other arm, which she used to gesture at a nearby building, marked by some streaks of white. "Or maybe didn't want people asking what she said to you," the mare added thoughtfully.
Derpy hadn’t exactly flooded the town, but she liked the think that she sheer force of her lactation, and the fact that the volume she’d spread about was far more than a mare of even her size should ever be able to create or store was finally burned into the minds of her neighbors.
“The kids?” Always her first thought after pulling herself together. Derpy believed in having fun for herself regularly as self-maintenance, but it was still in service of her family. Her back and wings were damp, so apparently she really had just lain there and milked herself until she'd been at the center of a lake of her own making. Some brave fool must have approached and helped her up to guide her to her current location at some point.
“Tops is watching them. Them and dinner. Put on a pot of lentil and potato stew.” Berry smiled. “You really gave them something to think about today, yeah?”
Derpy winced as she stepped onto dry ground. “I think my nips are gonna hurt all week, Berry.” She accepted the towel and covered herself. “Was a bit uncomfortable, in general.”
“You don’t gotta top yourself anytime soon,” her partner suggested. “Let the townsfolk be happy every time you don’t put in an effort, yeah?” Berry never seemed particularly invested in Derpy’s growth, but knew what to say, more often than not. “Even when you get bigger, they can wonder what’d happen if you tried this hard again.”
Later, in the darkness of their bedroom, Derpy enjoyed Berry's closeness and warmth. "Should I be worried?"
Berry lightly touched her hand under the covers. "Hm. Could you be?"
Derpy couldn't help but giggle. "About boring things, sure. About me? I don't think so. Everything is so amazing, Berry. I wish you could just spend one day in my body."
"Tell me about it." It was a familiar game. Talking about Derpy's boobs openly somehow made them even more enjoyable, and Berry readily went along with it.
She could hear Berry adjust her position to face her. Derpy sighed happily. "They're so heavy. And they got even bigger and heavier today. But it only feels good. Great, even." Even now she felt their weighty presence on her chest. She took a deep breath. "Like I'm built to carry huge boobs. Gigantic ones. And my hips got wider! I've always been a bit jealous of you on that front."
"Mmh." Berry's touch brushed across the side of Derpy's breast.
"And the milk!" Derpy's large nipples grew erect, waiting only for her command to start gushing once more. Fortunately, after the day's entertainment, they waited patiently, for now. They were still sore, which was quite extraordinary. Her beautiful breasts hadn't provided anything but pleasure in recent years. Still, it was oddly comforting to know that her flesh found limits before her productivity did. "Today was incredible." She rubbed her thighs together. "It w-was a drop in the bucket!" Even the memory of that euphoria was beautiful.
"I just wonder why," she muttered dreamily.
"Why?" Berry sounded genuinely curious, because Derpy hadn't been in the habit of questioning her gifts.
"Why, why do I still feel all that milk I'm not using?" Just thinking about it, Derpy felt as though an enormous liquid weight was pressing down on her thoughts for just a moment. "I tried so hard today but ... I can't share my milk faster than I'm producing it. I'm never gonna be able to use that reserve. And there's always m-more." She moaned the last word, her arousal spiking with the acknowledgement of the impossibility.
"Huh." Berry shifted her weight, then went back to gently rubbing at Derpy's breast. The tender ministrations served to soothe rather than inflame Derpy's lust, and both mares enjoyed the act. "I guess you'll just have to be immortal so all that milk doesn't explode into being and flood the country once you kick the bucket."
Flood the world.
Derpy rolled her eyes. "You're always such a pessimist." Warmth pulsed from her breasts reassuringly, as though to tell her that Berry's scenario was impossible.
"Maybe," Berry allowed. "But whether it's real or just a trick of your boob-obsessed brain, you can just take it as a constant reminder of what your jugs already did. What they'll keep doing."
Forever.
"They are pretty impressive," Derpy agreed, taking a moment to enjoy the slow waves of pleasure flowing between her crotch and her boobs without urgency. "I feel so ... so full of life. So fertile." It was a pleasant feeling, although she had no intention of getting knocked up again. While having huge tits and being surrounded by countless ponies who enjoyed her milk was a nice fantasy, she'd prefer if all those ponies were the responsibility of someone else.
"Heh. You want more kids?"
"Hm." Derpy's breasts throbbed eagerly. "Boobs are telling me I could feed ...any number. But honestly, I'm okay with never changing a diaper again."
"I'd just as soon never be pregnant again myself," Berry stated. "I'm just gonna forge ahead. We could adopt?"
Berry had always been very poor at establishing emotional connections with other ponies and their daughters hadn't been exceptions to that rule. It had taken time for Berry to grow to love them, so the suggestion was quite unexpected to Derpy.
"I'm listening."
"We make a pretty good team, yeah? I think we could take care of an older kid. Someone who needs emotional support not, y'know, babying." Berry chuckled. "You were the first pony who made me feel you wanted me around. Me, not the big goon who knows how to shank people. I think giving that to a teen would be a win all around. Except, y'know, for the baggage, but you handled me alright."
Derpy cuddled up to Berry, squishing her breasts against her lover. "I'm not against it. Let's talk more later." She was pretty sure if she hadn't had the opportunity to be emotionally nurturing to the other mare and their two daughters, Derpy would be a very different mare right now. Although having Dinky might have been what triggered her awesome boob powers, so maybe that thought was moot. If she weren't doing right by the ponies closest to her, it'd be a different sort of mare living in her skin.
She enjoyed the idea of providing a home, a sense of belonging to another pony, tho she was curious how a young teen might react to Derpy's proclivities. Her growing notoriety might not appeal to a prospective adoptee, and Derpy assumed that older children would have the final say whether a permanent arrangement suited them. A period of fostering would answer those questions, she supposed. If she was honest with herself, more ponies who'd see her as a person and not just a huge pair of tits would also be welcome once Derpy reached ever greater sizes. Both perspectives were necessary at different times and from different people.
Life was good and getting better. "Good night, Berry."
