How Sis Get Pregente

Berry Brew was many things. She was intelligent, beautiful, possibly one of the greatest ponies to ever live, but these were just the base facts. She was also an alchemist with a perverted streak wider than Ghastly Gorge. Many of her potions were geared towards catering to any sexual desire a pony or other creature would have. And, naturally, Berry tested these on herself first to make sure they worked.

Also to get her rocks off.

Oh, but she was an exceptionally diligent alchemist. After all, you couldn’t just put a futa fertility potion on the market without rigorous testing. What if some lesbian tried to fuck babies into her girlfirend and it didn’t work? So, naturally, Berry had personally tested it out on one or two dozen mares. They wanted babies anyway, so it was fine.

Berry was actually currently engrossed in the due alchemic diligence that was expected of her. Only a few weeks ago, she had discovered that through combining a futa potion with an elasticity potion, she could not only shove things down her dick, but she could digest them into cum. She had been practicing with ever increasingly large things and had also moved her operations to her basement. Because the basement had a drain in the floor and, naturally, her cumshots were getting exponentially bigger.

Today she was up to watermelons. Several watermelons, in fact.

“F-f-f-four!” Berry stuttered out, her hooves shaking so much it was a minor miracle she was able to make the mark in her notebook straight. Her stutters and shakes weren’t from pain, however. Quite the opposite.

Berry felt every centimeter of the watermelon’s journey down her cock, like the three before it. The pleasure of it was almost enough to make her cum. She managed to stave off her orgasm through sheer force of will, the lie about it being for the sake of properly measuring something or another sustaining her.

She was sitting in a chair near one of the walls, a small table for her notebook to her right. Her cock throbbed and bobbed in front of her, long enough she could kiss the flared head of it without leaning down, and her oversized balls were now sagging onto the cool stone floor with the weight of three, soon four, watermelons inside them.

The final one finally dropped into the blue mare’s balls with a fleshy thump, followed by a squirt of precum from her cock. The volume of it was enough to put most stallion’s proper cumshots to shame, but Berry didn’t bother making note of that anymore. She hugged her cock against her body, wrapping all four legs around it. Her balls clenched and churned, breaking down the fruit in her loins faster than a stomach could. Her nuts swelled to the size of a pony as the bounty of four watermelons stretched her pliable skin.

Berry jerked her cock with her legs, her technique having been honed over many, many, many tests. She had it down to nearly a science, knowing just how and where to touch herself to make her blow a load better than any volcano.

She angled her cock away from herself as MT Berry Brew erupted with the force of a cannon, her cum arcing the length of the room. Normally, she wouldn’t have minded the cum bath, but past experiences had taught her that jizz stuck the pages of books together just as good as glue and her notebook was well within the splash zone.

As Berry pumped several gallons of cum through her dick, she was able to gather data on another of her little experiments. She couldn’t say where she got the idea to put taste buds on the inside of her dick from, only that it was piss-easy to do. A little powdered squid pony tentacle and some changeling slime and poof, tastebuds inside her dick. The watermelons hadn’t been anything spectacular going down, but coming back up? Watermelon flavored cum was something Berry never knew she wanted until she was shooting it all over her basement floor.

She should have bought a bucket or barrel down here with her. She was almost certain that, with a little food dye so it was red, she could have bottled the spooge and sold it as some sort of protein shake or something. Ah, maybe next time.

Berry let out a deep, satisfied, rattling sigh as her orgasm winded down, her geysers of cum petering down to relatively small spurts and finally just dribbled down her shaft and balls. The drain in the floor gurgled as the viscous fluid drained down it. Berry knew she needed to dump some water down it too, lest her jizz clog the pipes. But, she was too drained at the moment from her orgasm. She slumped back in her chair, cock wetly slapping against her chest.

Still, even as her whole body felt sluggish, a smile stretched the red-maned mare’s lips. Because, it just so happened that the average pony had roughly the same mass and weight as four good-sized watermelons. Now, Berry wasn’t sure she could cock-swallow a pony and turn them into foal batter. But, well, it would be downright neglectful of her as an alchemist to not see if she could.

She heard the bell attached to her door jingle faintly, signaling she had a customer. With a sigh and a groan, Berry got up and quickly set about making herself presentable...

Honey Heart was a pretty unassuming sort of mare. And that was both ways. She didn’t assume much about any other creature and they in turn assumed very little of her.

She was a bit taller than most mares, her legs long and slender, giving her an almost gangly look. Her coat was snow white with some pink coloring at the tips of her hooves and ears, some adorable heart shaped freckles on her cheeks and flanks, and of course her cutie mark, which was a pair of wide hearts that covered the back half of her flanks. Her mane and tail were a paler tint of pink and her eyes a darker, more vibrant shade. Overall, she was a rather cute pony if she did say so herself, and plenty of other creatures liked to tell her she was cute too.

Honey Heart trotted down the streets of Canterlot, near the river that ran through the city. The water bubbled and babbled as it washed through the canal, sometimes splashing up onto the walkways around it and making the ponies near it wet. Honey didn’t mind it too much. It was a rather warm day, so a little cool water on her coat was welcomed. Her brother would have enjoyed it much more, naturally.

Sweet Heart, that was his name, wasn’t with Honey at the moment. He was busy tending to their candy shop while she ran off to fetch ingredients. That’s what she had told him when she left, anyway. Sweet liked to worry and Honey hated to give him more reason to worry.

The quiet mare turned off the main road and down a small side street. The bright, shining aesthetic of Canterlot gave way to something older and perhaps a bit uglier. The city liked to present itself as all yellow gold and white silk, but the old Canterlot still existed in certain places. This was one such place, all gray stone and brown wood, wet and mossy from the river. It was a little seedy, a little grimey, but the creatures here were just as friendly as anywhere else.

They just offered certain services that were a bit… less polite.

Honey trotted down the small stone staircase to Berry’s Brews, a small potion shop with a certain reputation. The proprietor could make just about any sort of potion you wanted and would keep quiet about it too, so long as you could afford her services. Honey lingered for a moment in front of the shop, checking to see if anyone else was inside. She felt embarrassed enough about having to talk to one pony about her issue, let alone allow for another to potentially overhear.

Thankfully, the shop looked to be empty, and Honey trotted inside. The interior was a little cramped, several rows of tables jam packed with all manner of potion ingredients and bottles of every size and shape filled with liquids of every color of the rainbow. Some even seemed to change color at random. The space available to move between the tables was rather limited, even for a mare as slender as Honey. She crept along slowly, trying to take care not to bump anything as she looked around for Berry Brew.

But, as the alchemist was nowhere to be found, Honey found her eyes drawn to the mare wares on display. The potions were all labeled with what looked like hoof-written scraps of paper, denoting what they did in rather plain terms with a little arrow pointing to the back where one could read the ingredients and associated warnings.

Honey found herself drawn to a potion the same color as the pink on her coat that claimed to be a love potion.

‘Make Yourself Irresistible!’ the label said with an excited flair. ‘Better than a Want-It-Need-It Spell Guaranteed!’ On the inside of the label, it listed the ingredients, none of which Honey recognized, with a helpful warning. ‘Effects of this potion are temporary and not guaranteed. Do not exceed the recommended dose. Brewer is not responsible for any injuries caused in conjunction with the use of this potion. Included but not limited to: rug burn, soreness of muscles, joints, or genitals, dehydration from loss of one’s liquids, loss of any body part after said body part was put in any orifice, accidental cannibalism, intentional cannibalism, pregnancies of any variety, or dry mouth’

“Looking to make yourself the center of attention?”

Honey nearly jumped out of her fur and skin by the sudden voice behind her, the bottle flying from her hooves. A pair of dark blue hoove quickly reached out and caught the bottle, saving it from smashing onto the floor,

“Sorry,” the red-maned mare said, setting the bottle aside, “I didn’t mean to startle you.”

“It’s alright,” Honey insisted, her smile apologetic. “I startle rather easily. Uh, my name is Honey Heart.”

“Berry Brew. And I have something for that too,” Berry said with a grin, setting the potion aside. “But, I get the feeling you came here with something else in mind.”

Honey nodded, her smile becoming a more nervous one. “I… I have an issue that I was hoping a mare like you would have a solution for.”

“Not trying to suck my own dick or anything…” Berry said with a self-sure grin, trotting up behind her counter and propping her forehooves on it. “But if you have a problem, one of my brews will fix it. So, what seems to be the problem?”

Honey averted her eyes. “It’s… it’s a little embarrassing.”

Berry snorted. “Honey, just two days ago I gave a stallion a potion to shrink his dick so his boyfriend could better humiliate him in the bedroom. And last week I gave a mare a potion to make her clit big enough to fuck her girlfirend with. And yesterday I gave some frilly little cheerleader something for her zits.” Berry cricked her neck and leaned down further on the counter. “It’s not my business what or why you want the potion. Just that I can make sure you get the right one.”

Honey bit her lip, blushing with embarrassment at how casually Berry Brew mentioned such salacious things.

“W-well, that’s comforting. B-but this isn’t for sex!” she added, speaking a bit louder than she meant to. “It’s, um… Well I guess it’s sort of related to sex…”

“Come on, Honey. Tell Doctor Brew what ails you,” Berry said, smirking as she watched the mare squirm. “Not too dry, are you?”

“No, nothing like that,” Honey said, approaching the counter and the mare behind it. “I… I’m having difficulties conceiving.”

Berry raised an eyebrow. “Like, your work or…?”

Honey smirked, amused by the alchemist’s coyness. “I mean conceiving a foal, Miss Brew.”

Berry clucked her tongue. “Ah, that. Well, I have plenty of things to assist with that. Tell me, what seems to be the problem, specifically?

Honey swallowed thickly. “W-well, I’m not sure.”

“Haven’t you spoken to a doctor or something about this?” Berry asked, tilting her head.

Honey shook hers. “No. A doctor would ask questions. Questions with answers they wouldn’t like.”

Berry raised an eyebrow. “Not planning on date-raping someone and trapping them with a foal, are we?” she said slowly, watching Honey’s face. “Because the potions to accomplish such things most certainly aren’t in the back room under lock and key, purely for academic study of course. And I also wouldn’t sell you that key for-”

Honey’s eyes widened with fear and Berry stopped short, smirking.

“Good, that was a test,” Berry lied through her teeth. “Just need to make sure you aren’t going to use any of my potions for… nefarious purposes.”

“O-oh,” Honey said, releasing a breath she hadn’t realized she’d been holding. “No, me and my, ah, partner both want this.”

“So what’s the hang up?”

Honey looked left and right, almost like she was scared someone was waiting in the shadows to pop out and arrest her. “You promise that anything I tell you stays between us?”

Berry held up her right hoof. “Cross my heart, hope to fly, stick a cupcake in my eye.” She mimed the motion of that last part. “And I’ll make sure it’s peanut butter so I just die from allergic shock. Now come on, spit it out.”

Honey nodded. “Right. So… the pony I’m trying to have this foal with… he’s my brother.”

Berry waited a few seconds, but nothing more came. “That’s it?”

Honey looked a little shocked that Berry had taken the revelation so well, but nodded. “Yes. I know it’s not illegal, but I’m certain I’ll get quite the lecture about it from any doctor I go to. And… I’m worried they might try to magically suppress my ability to conceive even more.”

Berry nodded understandingly. “Unicorns. They fuckin’ would, let me tell you.”

“My thoughts exactly,” Honey nodded again. “I know it must be difficult to work without knowing exactly what the problem is, but I was hoping you could give me one for each and that will hopefully sort out the problem.”

“Hmmm, maybe…” Berry said, giving Honey Heart another look over. She was an attractive mare, the sort Berry wouldn’t mind testing a few impregnation methods out on. In fact… “Tell me about this brother of yours.”

“Oh, Sweet Heart is… well, he’s a real sweetheart,” Honey said with a blush and a grin. “We’re twins, so we’ve always been close. We run a little candy shop in the market. Well, I just manage the books and whatnot. Sweet is the one who handles the cooking.”

“Mmm, sounds lovely,” Berry said, nodding. “He’s your twin you say?”

“Mm-hm, identical twin, in fact.”

Berry’s eyes widened and her cock, taped against her barrel where it was mostly out of sight, twitched.

“Oh really?” Berry said, licking her lips. “Well, I’m more than happy to help. But…”

Honey trotted a bit closer to Berry, ears and nose twitching nervously, her prize so close and yet suddenly in danger of being snatched away.

“W-what’s the matter?”

“Well…” Berry said, stalling for a few moments while she tried to think up a viable excuse. “You see, since we’re going to be using a bunch of my fertility potions… Uh, they’ve never been mixed together like this, you see. It’s still perfectly safe, of course,” Berry added quickly. “But, I’ll need to be there to observe the effects. For posterity.”

“O-oh!” Honey said, blushing as she realized the implications of what Berry was saying. “That’s, um, hm…”

“It won’t be invasive or anything. I’ll just ask you a few questions before and after. And I’ll leave the two of you alone for the more intimate part,” Berry said gently. “And I’m happy to give you a discount too,”

Honey held a hoof to her chin, seeming to consider it. “What sort of discount?”

Berry grinned. “Well, I think since you’ll be providing me with very useful data, I think a fifty percent discount would be in order.”

Honey’s eyes widened. “Really? Oh Celestia, that would be wonderful!” She nodded excitedly. “I’ll have to talk to Sweet about this, but I’m sure I can convince him.”

“Good, good. You two should also come here for it. Just in case anything happens, I’ll have everything right here to help,” Berry said. She saw uncertainty creep back into Honey’s face, so she quickly added, “I have a guest room that I keep very tidy, I assure you. Just like a hotel. Nice view of the river too.”

“Oh, that sounds really nice. Thank you,” Honey said, her smile wobbling a little as she looked Berry in the eye. “Miss Brew, these potions… they’ll help me get pregnant, yes? I know what you’re going to say, but- Please understand I want this more than anything.”

Berry put on a confident smirk, her eyes glittering with predatory intent.

“I promise you, Honey Heart. By the time we’re through, you’re going to be too pregnant to stand.”

A full day and change had passed since Honey Heart had come into Berry’s shop. The mare had agreed to come there tonight and bring her brother/baby daddy along with her. Berry had hardly slept, more than a little giddy at the prospect of what she was about to do. So, she instead took the time to make any and all preparations needed, preparing her basement for the lovely couple.

Sunset came much too slowly for Berry’s liking, but at least it came. She made sure to close up her shop a little early and shoo out any lingering perverts that seemed to show up at her doorstep near dusk. If that Sol fellow wanted to make his dick squirt vanilla frosting he’d have to wait until tomorrow for the necessary potion.

She turned the sign in the window over to ‘closed’ and did some last minute tidying up. She couldn’t, and more importantly didn’t, clean up the whole shop. She would probably need a full wrecking and construction crew for that. But she did spruce up one corner, sweeping the floor, bringing over a small table, and throwing up a few curtains and lighting a scented candle. Supposedly the aroma made ponies horny, but Berry was too worked up already to be sure if it worked. Smelled nice, though. Like honeysuckle.

She wasn’t sure if the couple of candy-makers were going to be dressed up, but Berry decided making herself look nice would help the atmosphere. She had an old casual tuxedo of sorts she last wore to one of those posh fru-fru restaurants with a dress code. It was a little tight in the withers, but otherwise fit nicely and certainly classed up her appearance.

There was a knock at the door just as Berry finished lighting the candle. She blew out and tossed the match in a metal bucket as she made her way to the front of the shop. As expected, the sister and brother were there. If it weren’t for their difference of clothes, Berry was certain she would have been seeing double.

Honey Heart had put on a simple pink dress and fluffed up her make-up. Nothing too extreme, but she had more color in her cheeks, some soft pink eyeshadow, and clear gloss on her lips. It was all well and good, but Berry was more interested in the brother; Sweet Heart.

Berry trusted Honey’s assurance that Sweet was a stallion, but he looked to Berry more like a mare who had borrowed her boyfriend’s clothes. The ruffled white suit jacket and matching shirt seemed just a bit too big and hung off his frame. He was remarkably similar to his sister as well, from his mane, coat, body type. Heck, he even wore a similar nervous expression.

Berry could have just eaten him up right then and there.

She pushed open the door to her shop and welcomed the pair inside.

“Good evening,” Berry said with an exaggerated bow. “I’ve been expecting you.”

“Ah, you must be Berry Brew,” the stallion said, offering his hoof. His voice was high and soft, but still discernible as male. “My sister has had nothing but good things to say about you.”

“Aw, how sweet,” Berry said, shaking his hoof and smirking at Honey. “Forgive me for prying, but what good things?”

“Just how you were kind enough to offer your services at a discount and be more than accommodating,” Honey said, nodding. “I may, uh, have neglected to mention just what services those were though,” she added with a wink.

“Oh? Well, I hope you like surprises, Sweet,” Berry said, ushering the couple into the shop.

“Depends on the surprise,” Sweet said with a nervous smile as he took in Berry’s place of business, seeming to marvel at all the bottles of colorful liquids scattered around.

“Trust me, you’re gonna love it,” Honey said, pecking her brother on the cheek.

“I took the liberty of setting things up for you,” Berry said, leading the candymakers over to the little table in the corner. At her bidding, they both sat down on either side of the table and then turned their attention to her. “Now, if you’ll wait just a moment, I’ll go get your surprise.”

Berry bustled off, leaving the siblings alone for the moment. She had stashed away all the necessary potions nearby in a small crate. She carefully balanced it on her back and returned to the happy couple. She had scarcely been gone a minute, but when she returned Honey and Sweet were already giggling and smooching. They quickly broke apart when they saw the alchemist, blushing and averting their eyes.

Stupid adorable incest ponies.

“Here you are,” Berry said, putting the crate down and then dolling out the potions to the appropriate ponies. “Now, I think Honey should be the one to tell you what these are for.”

Sweet looked down at the two glass phials in front of him. One was filled with a milky liquid, chalky blue in color. The other was filled with something that looked like reddish-brown mud. And the last held an opaque, slightly viscous liquid. Across from him, Honey was given three potions to drink. One glowed neon pink, another was a pearly white, and the last was the same thick stuff he had. He looked from the potions to Berry and then to his sister, raising his eyebrow.

“Honey…” he said slowly, not quite sure what was going on.

“Sweet, you know how we’ve been… trying to have a foal of our own?” Honey said, gently laying her hoof over Sweet’s.

Swett nodded, his brow furrowing in concern. “Yes…”

Honey smirked and chuckled, the sound more nervous than anything else. “Well, Miss Berry Brew is an extremely talented alchemist. I’ve heard nothing but good things about her. And, when I told her our problem, she agreed to help.” Honey nodded at the potions on the table. “Since we’re not quite sure what the problem is, Miss Brew was kind enough to make potions to address whatever concern it might be. And she even did so with that discount I told you about.”

Berry nodded. “The only catch is, I want to see what happens. I’ve never had ponies on all of these at once. It’s perfectly safe, of course,” she added quickly. “Still, I think the way the potions will interact will be… interesting at the very least.”

“So, you want to observe for research?” Sweet asked.

“Indeed,” Berry replied. “And because I’m a huge perv.”

That seemed to ease the tension in the room, both siblings laughing at Berry’s joke.

“Thank you, Miss Brew, truely,” Sweet said with a big smile and a nod. He returned his attention to the potions. “Now, what do these do?”

“The pink is for mare fertility,” Berry said, tapping the pink potion “then the white is increased vaginal wetness and sensitivity. The blue one is for increased sperm count, the red stuff is going to make your jizz really good and strong. And the last two are going to make you two horny as rabbits on coming out of hibernation.”

Both siblings blushed, but nodded their understanding.

“I’ve also prepared a nice little place for you to get busy downstairs. So, drink up so we can get to foal making,” Berry said with a predatory grin.

Sweet and Honey exchanged looks and then both took up their first potion. Blue for him, pink for her. They drained the bottles easily, fertility potions always did taste sweet, as Berry knew. The second ones would be harder. The red stuff was thick and, based on what Berry knew, tasted like brownies that had fallen in dirt. Sweet made a face, but dutifully swallowed every last drop. The pearly stuff was easier, slicker than oil so it went down easy, even if it did taste like sea water.

Then there was the last potion.

Berry had lied about that one. The other potions would make them plenty horny. The slightly thick and sticky stuff was what Berry liked to call a popper. It loosened ponies up, made them giddy and dopey, easily pliable.

Berry had to bite back a grin as the siblings drank the popper, smacking their lips.

“Mmm, tastes like…” Sweet said, reaching for something he couldn’t quite grasp.

“Sugar water!” Honey finished for him, suddenly overcome by giggles.

“Yeah!” Sweet replied, nodding rapidly. “Man, I haven’t had sugar water in forever. It’s such a bad idea.”

“Well, I’ve got a good idea,” Berry said, allowing herself a smile now as she nudged the ponies up from the table. “Let’s go down to the ‘honeymoon suite’.”

She led the increasingly giggling pair of ponies to the back of the shop and then down the old stairs to the basement. She went slower than she wanted to, a necessity to keep either one from losing their balance and falling. Berry made a mental note to only give ponies a popper after they had gotten to wherever she wanted them.

Thankfully, they reached the base of the stairs without incident, although both ponies were swaying on their hooves.

“I’m feeling kinda weird…” Honey said, moving unsteadily on her hooves, her words beginning to slur together.

“Aw,” Berry said in a sickly sweet tone. “Let’s get you up somewhere more comfortable.”

Berry left Sweet Heart to wobble unsteadily near the stairs and she moved to Honey, putting a hoof on the mare’s shoulders and steering her towards the far wall. There was a mattress there, brand new and already covered in some sort-of-nice blankets. Berry pushed Honey onto it, letting the mare collapse on her front, her ass ending up sticking straight up in the air.

With the sister more or less where she should be, Berry quickly moved back to the brother. She grabbed Sweet and pulled him over to his sister, nudging him until he nearly ran muzzle first into his sister’s rear. Berry giggled as the pair made cute little oomph noises and she worked herself out of her clothes. She tossed them aside and pulled up a chair to relax in while she watched.

“Heh, s-see something you like, bro?” Honey said with a blush, wiggling her rump and flagging her tail over Sweet’s face.

“Fuck yeah, sis,” Sweet replied, sounding for all the world like a schoolboy trying out his first swear. “B-but, uh, turn around.”

Honey looked over her shoulder, bemused. “Huh?”

“I-if we’re gonna do this, I want t-to look into your eyes,” he said, blushing hotly and averting his eyes.

Berry chortled, but put her hoof over her mouth to stifle the noise. Sweet Celestia, these two were too damn cute.

“Aw, Sweet,” Honey said, drawing out the name as she laid herself down on the mattress and then rolled onto her back. “Like this?”

Sweet nodded excitedly. “Yeah, just like that.”

The light may have been low, but Berry saw Sweet’s dick slide out of his sheath, hard and ready for fucking. It was just as pink as the twin’s cutie marks and while not huge, it wasn’t small by any stretch either. Sweet crouched low over Honey, his hips thrusting jerkily and missing her cunt a few times. His dick twitched and throbbed, and Honey giggled.

“Hehe, having a little trouble, Sweet?” she said, sounding like she was giving her brother some good natured ribbing.

“A little,” he replied, blushing with as much embarrassment as arousal. “Your fault for being so wet.”

“Is that so?” she replied, grabbing his sides with her forehooves and holding him still. “Well, why don’t I help you then.”

Sweet nodded, shivering with anticipation as Honey’s hooves slid down his barrel and between his legs. Delicately, she took his cock and guided it to her wet folds. They both let out a pair of cute little gasps as his flared head kissed her entrance, followed by deeper moans as he jerked his hips and properly penetrated her.

Berry licked her lips and slouched in her chair, reaching her hoof down to stroke her cock to life. Her own dick was currently no bigger than Sweet Heart’s own, but she had a way of fixing that. She held off for the moment, though, eyes glued to the siblings.

Honey wrapped her legs around Sweet’s barrel as he thrusted into her, spearing her fully on his dick in one go. The mare moaned and the stallion groaned, the voices mixing together into a complimentary melody of pleasure. True to his word, Sweet leaned in close over his sister, staring deeply into her eyes as he worked his hips. The low angle of the mare on the mattress made things a little awkward, but Sweet soldiered on, the steady plap of his hips against hers filling the basement.

Berry wondered if the twins ever masturbated to their reflections in the mirror, considering how closely the two resembled each other. Berry herself had done it a few times, but then again she was a damn sexy pony. As she idly stroked her cock to the incest happing before her, she wondered if she should track down a changeling and see what fucking herself really was like.

Honey grabbed Sweet’s head and pulled him down into a kiss, her other hoof snaking down and giving the stallion’s plump rump a sharp slap. Even muffled by his sister’s mouth, Berry heard Sweet squeal. He didn’t break the kiss, though. And he started fucking his sister even harder.

Juices dripped down from the mare’s groin, soaking the mattress under her ass and even beginning to pool on the stone floor. The puddle of mare-honey slowly began sliding towards the drain in the floor and Berry’s eyes were pulled away from the twins just long enough to acknowledge it. Damn, the mare was really wet. Berry made another note about investigating that further. Everyone always thinks about a stallion cumming a bathtub’s worth of jizz, but Berry was willing to bet there were those out there who wanted the risk of drowning when a mare squirts.

Speaking of squirting, Honey Heart did that with a sharp squeal, pulling Sweet harder against her lips as a spray of her juices splattered against his groin. He didn’t so much as pause, however, dutifully fucking her with the same fast and hard rhythm. His balls slapped wetly against her ass as Honey finally broke the kiss, falling back on the mattress and moaning as she was fucked into it.

Berry spoke for the first time in minutes, managing to make the pair of incestous ponies jump.

“Don’t cum in her, Sweet.”

“Wha...?” Sweet said, slowing but not stopping the motion of his hips as he glanced over his shoulder at the blue mare. “But I thought-”

“The potions haven’t quite taken effect yet,” Berry said, lying as easily as she breathed. “And you don’t want to fill your sister up with lesser jizz, now do you.”

“Y-yeah,” Sweet nodded, seeming to accept her reasoning. “Sorry about this, Honey.”

Honey, who was just a little too blissed out to notice the conversation happening right over her, blinked in confusion. “S-sorry about what?”

Sweet broke free of Honey’s back leg grip, pulling his dick out of her cunt and clamoring over her body. Before the mare could piece together what was happening, her brother’s dick was in her face, slick with her juices and throbbing. Sweet reached down and grabbed his dick, stroking it rapidly. He had already been close, so it didn’t take long.

Honey let out a surprised squeak when the first spurt of cum splattered over her face. She then smirked and giggled, shooting her brother a sideways look as she took over cock-jerking duties with her equally soft hooves. She worked another two healthy spurts of spooge out of him, getting a nice facial of foal batter. The last bit dribbled down her neck and chest, sticking in her fur. She didn’t care, the musky-sweet smell and warmth not just familiar but exhilarating. She and Sweet had been trying to get her pregnant for so long, she couldn’t quite remember when she had last taken a load to the face.

“Oh fuck…” Sweet groaned, his legs shaking before he collapsed on the mattress beside Honey. “Th-that felt even better than, unf, usual.”

“The wonder of my brews,” Berry said, chuckling as she watched the pair of prospective pony parents catch their breath.

“I think you came more too,” Honey said, wiping some jizz off her face. “I don’t suppose you could help me clean up?”

Sweet grinned. “Of course.”

He turned himself on his side and dragged his sister close, nuzzling against her neck before planting a kiss on her glazed cheek. She giggled as he began to lick her clean, quick swipes of his tongue lapping up salty-sweet jizz. In no time at all, he had licked her face and chest clean, her fur now matted with saliva instead of spooge.

“Kinky,” Berry said with a smirk. “Now, why don’t you give your sis a rest and come over here, sweetie?”

Sweet chuckled and gave Honey one last peck on the cheek before getting to his hooves, his legs wobbling a little. He trotted over to Berry, slowing a little when he caught sight of her still hard dick. He began to sway unsteadily as well, blinking slowly as the potions he had been fed earlier continued to work through his system. Berry just grinned and hopped out of her chair, pulling Sweet close once he was in reach.

“You okay there, Sweet?” Berry asked, still smiling like a cat with a cornered mouse.

“I’m feeling a little woozy…” Sweet said, glancing down between Berry’s legs and then back at her face. “Uh… do you have a dick?”

“Sure do,” Berry said with a laugh. “Don’t worry though, cutie. I’m not gonna shove this up your butt or anything. Even if you’d enjoy that.”

Sweet blushed and averted his eyes while Berry just snickered. She dragged the sluggish and unbalanced stallion into the center of the room, pushing him down onto the floor. She had scrubbed it earlier that day, but the stone floor was uncovered and uncushioned and the pony grunted as he landed heavily on it.

“Sorry for the poppers, loves. But I couldn’t have you too getting cold hooves about this. Or fighting back,” Berry added with a laugh. “Mmm, it’s downright criminal how yummy you two look. It’s like you’re begging to get snatched up. Better me than someone else though, right?”

“Bwuh?” Sweet said, looking at her with unfocused eyes.

“Don’t worry, lover boy. You’re gonna enjoy this next part.” Berry said as she trotted over to the cabinet on the wall. She retrieved one of the potions she had stashed there earlier and chugged it.

Earlier she had taken a shrinking potion so she could actually fit her massive cock and balls into her pants. A necessary evil for when a pony didn’t want to bother with all that unreliable illusion magic bullshit to hide their naughy bits. This was the antidote of sorts and it worked perfectly, as expected of any Berry brew. In less than a minute, Berry’s meat and two veg went from smol to LARGE, her nuts swelling up to the size of particularly big oranges and her cock lengthening and thickening until the head extended just past her chest and it was as thick as one of her legs.

“Mmmnnnfff,” Berry groaned, the pleasure centers of her brain dancing as her cock grew out. “Fuck, that feels nice. Heh, it’s not gonna compare to what’s coming up next, though.”

“What happens next?” Sweet asked, looking at Berry’s dick instead of her face.

“It’s simple. I’m gonna get your sister pregnant. And you’re going to help me.”

Sweet’s eyes widened as Berry advanced on him, her dick leaking precum as it bobbed under her barrel.

“See, either your little swimmers are too wimpy to knock her up, her cunt is just way too hostile for them to survive. Heck, maybe it’s both,” Berry leaned down close in Sweet’s face and took his chin in her hoof. “But I gave her just about every fertility potion I had and I can personally tell you I’m shooting ten out of ten when it comes to knocking mares up. The only hitch is making sure you’re part of the process.”

“Uh…” Sweet said dumbly as the flared head of Berry’s cock booped him on the nose. The scent of her was overpowering, musky and masculine, with sweet, fruity undertones. It made his dick twitch with excitement. “H-how’s that work, exactly?”

“Even simpler,” Berry said with a smirk. “I’m gonna feed you to my cock, churn your cute ass up into cum, and pump it right into your sister’s womb.”

Even though he had enough exotic plant extracts flowing through him to body a college frat, that seemed to sober Sweet Heart up real quick.

“Wha-?” was all he managed to say before Berry bucked her hips and forced his muzzle into her cumslit.

Berry bit her lip and groaned deeply, back legs trembling as she got her first taste of a pony in her dick. Literally. The tastebuds she had given herself in her cock were still working and she could taste the girly stallion’s face, the subtle hints of sweat and cum lingering in his fur. Sweet himself was having difficulties processing what was happening. A life of making sweets and fucking your sister didn’t exectly prepare you for suddenly being up to your eyeballs in some mare’s cock. It was warm and slick, precum slathered over his muzzle and dribbled into his mouth as Berry’s body responded with excitement to the pony being fed to it.

If given enough time to gather his thoughts, Sweet might have thought to pull his muzzle back out. It was pretty lubricated, all things considered. Luckily, Berry didn’t spend too long savoring the first ‘bite’ and quickly put her hoof on the back of Sweet’s head. She shoved him down in time with another thrust, sucking his head completely into her cock. Her hips bucked involuntarily as another wave of pleasure rolled through her.

Berry panted as she quickly fed more of the tasty pony into her dick. Her cock stretched easily to claim his shoulder and slurp down his chest. His rather slender build worked in her favor, Berry having to hardly do anything as her cock reflexively sucked Sweet down past his barrel and belly. She could really taste him properly now, and while she wasn’t sure if it was the shampoo he used or just something natural, but Sweet Heart really did taste sweet. A succulent, meaty flavor Berry couldn’t quite say she had ever tasted before. Did all ponies taste this good? She certainly hoped so.

Sweet was wiggling, but he really started thrashing and kicking his legs when his head moved from Berry’s cock to her balls. He gasped as the cloying, smothering weight and heat of Berry’s cock gave way to a more open space. The smell of her cum was choking him now, so thick in the air it felt like he was already submerged in the stuff. He could hardly believe this was happening. In fact, it couldn’t be happening, right? No way in tartarus this was actually happening right now. The potions she had given him, they must be reacting badly, making him hallucinate.

Berry plopped herself down on her nice ass, spreading her legs wide to allow for her stretching balls as she gripped her pony-stuffed cock with both hooves. Sweet’s slim, shapely hips slipped past her cock-head, his dick twitching back to life as it slipped into the tight, slick heat of Berry’s significantly bigger member. Why exactly Sweet was popping a boner Berry couldn’t rightly say nor did she care. She leaned back, closing her eyes and moaning openly as Sweet’s legs slipped into her dick.

She could feel his little hard-on pressing against the inside of her cock, taste it too. It felt good. Too damn good. Berry trembled as more of Sweet was stuffed into her balls, as his fetlocks tickled her flare as they slipped past. She didn’t want to cum, waste all the work she had done to get to this point. She tried to think unsexy thoughts. Paying her taxes, using ethical alchemic practices, that bitch Rym Waggles. It worked, more or less, as Sweet’s cute little hooves got slurped into Berry’s dick, sucked down to join the rest of him as he swelled Berry’s nutsack.

Sweet found himself squeezed down and forced to curl up in Berry’s surprisingly stretchy balls. Well, if her cock could stretch to swallow him up, why not her balls too? Cum stuck to his fur like glue, thick and hot, more seeming to appear by the second. His dick, hard in spite of the general uncomfortableness, was pressed up against one of the walls of his fleshy prison. He still couldn’t believe this was really happening, reasoning he was probably passed out and having a particularly vivid nightmare. Well, nightmare or not, he humped against the warm flesh pressed against his cock as best he could with such limited space. It wasn’t Honey’s pussy, but it wasn’t all that bad either...

Berry’s tongue lolled out of her mouth as her balls clenched and churned around the newest occupant. She felt his cock against the inside of her balls, felt the stallion trying to fuck her nuts from the inside. She snickered, slurping her tongue back into her mouth as she put her hoof right down on that particular bulge. She rubbed against, fast and hard, until she felt Sweet give a particularly hard jerk along with a sudden blossoming of warmth.

That warmth was quickly swallowed up by the sheer amount of heat her balls were producing, just as Sweet was swallowed up by the rising cum filling what little space remained in Berry’s balls. Berry bit her lip again as her balls went into overdrive, sludging the stallion in under a minute.

The lumpy shape of her balls soon smoothed out as they swelled with a full pony’s worth of cum. The alchemist had to take a moment to run her hooves over the swollen flesh, marveling at the weight, the way her nuts jiggled when she prodded at them. It felt different than the watermelons. Heavier, somehow. More satisfying. Another low moan came from Berry’s throat, her hooves going to stroke her dick almost of their own accord.

She managed to stop herself before she wasted her load. She owed at least some of it to the mare laying on the mattress not twenty feet away with a dopey smile on her face.

Carefully, Berry got to her hooves, her nuts sloshing as she moved, the sheer size of them forcing her to walk bowlegged as she trotted over to the cabinet to retrieve another potion. Holding the bottle carefully in her teeth, Berry approached Honey Heart.

“Oh, hey there, Miss Brew,” Honey said with a giggle. “Have you seen Sweet? He kinda wandered off…”

“Oh, he’s closer than you think,” Berry said around the bottle before she put it on the floor beside the mattress. “Ready to get pregnant?”

“Oh, yeah!” Honey said, her eyes lighting up as she rolled onto her front and started to sit up. “Is Sweet ready to go again? I hope you gave him some stamina potions too.”

“Heh, he’s ready to go, alright,” Berry said, licking her lips as she looked Honey’s body over. She wasn’t the sexiest mare Berry had ever seen, or even the sexiest she had fucked a foal into, but she was still nice to look at. “Ah, but you should drink this first.” Berry nudged the potion towards Honey.

The mare picked up the bottle and peered at it and then Berry, skeptical in spite of the potions already zipping through her body.

“What for?”

“Stretching,” Berry said, in a rare moment of honesty. “I mean, unless you think you can take this monster and not die.”

Berry punctuated the sentence by thrusting her hips and drawing Honey’s eye to the mare-breaker of a cock the alchemist sported.

Honey’s eyes widened and her jaw dropped. “Woah, that’s a big dick.”

Berry snickered and nodded. “Yeah, it kinda- ooh!”

Honey had leaned forward and ran her tongue over Berry’s flare, stopping the futa mare mid sentence. Honey herself let out a low groan as she lapped up the sweet-tasting precum Berry’s cock was drooling. If she could taste any of her brother in it, she didn’t bring it up.

“Mmm, yummy,” Honey said, giving Berry a dopey smile. “You taste almost as good as Sweet.”

“I-I’ll take that as a compliment,” Berry replied, a shiver running from the tips of her hooves all the way up her spine. “You should drink the potion before I get impatient and take my chances on you popping like a water balloon.”

“Fiiiiiiine…” Honey said, bringing the potion bottle to her lips. She stopped once more, brow furrowing as she seemed to remember something. “Wait, I want to have Sweet’s foal, not yours. I mean, no offense.”

Berry clenched her teeth, but forced on a smile. “Sorry, I forgot to mention. He, uh, helped make this big load of cum I got here,” Berry said, patting her swollen nuts. “So, it’s basically gonna be him getting you pregnant, see?”

Honey looked skeptical for a moment then nodded. “Okay!” She downed the potion without another comment, swallowing it and then shuddering and smacking her lips. “Ugh, tastes like rubber bands.”

“Yeah, it does,” Berry said, inching closer while her cock throbbed and twitched. “Here, I got something to get that flavor out of your mouth.”

“What’s tha- mmph!” Honey said as Berry’s impatience boiled over and she grabbed the other mare’s head, holding her in place while she forced the head of her cock past those pretty lips. “Fooda guss’d,” Honey mumbled into the thick sausage stretching her jaw.

“Ah, that’s nice…” Berry said with a happy sigh, lightly moving her hips, working the first few inches of her dick into Honey’s mouth, teasing the back of her throat with the big flare. Any other day, Berry might have taken the time to proper throat fuck the mare, but she didn’t want to risk blowing her load down Honey’s throat by accident. She had a job to do, after all.

Berry indulged herself a little, though, just enough to squeeze a bit of sweet pre-cum onto Honey’s tongue. She pulled free of the mare’s maw with a wet pop, letting her guest savor and swallow her treat.

Honey gulped and smacked her lips. “Mmm, that’s better,” she licked her chops, and held a hoof to her chin. “Hmm, that’s really good, actually. Maybe you should come by the shop some time. We could make some really fun candy with this.”

“Pretty sure that’d be some kind of food and drug violation, but that’s never stopped me before,” Berry said with a smirk, lightly pushing Honey onto her back and clamoring over her. “Maybe we can try it while you’re on maternity leave.”

Berry crouched low over Honey, sandwiching her cock between their bodies. Honey laughed breathily, eyes glued to Berry’s cock as the alchemist worked it between them, more pre-cum leaking out onto Honey’s already sticky chest. Berry grinned and shuffled back, dragging her dick along Honey’s body until she was able to line it up with the mare’s already wet cunt. It looked like Berry was lining up a full sized pickle with an ordinary straw, but that wasn’t exactly going to deter her.

Berry tried thrusting in a few times, her fat flare slipping over Honey’s petite pusy lips, but she got it eventually. Honey moaned as the first couple of inches of Berry’s dick sunk into her, stretching her love tunnel more than Sweet ever had. Oh, she never had any complaints about Sweet’s size, especially considering how well he fucked her, but there was just something about feeling her flesh being pushed and pulled to accommodate a truly massive cock. Honey’s heart hammered in her chest as she felt her hips shifting to allow the monster in, the stretching potion surely the reason she was able to take even this small amount of dick without something tearing or breaking.

Berry bit her lip and moaned. She only then realized she had yet to actually test her big ol’ stretchy dick out on a pony. She’d fucked ponies with her futa cock before, but it was never this big. The sensation was amazing. Hot, wet tightness she had known before, but this was even better. She could feel Honey Heart’s flesh stretching and hugging her tightly, like a pair of socks a few sizes too small. Sweet Celestia, she wasn’t even halfway in yet.

Berry grabbed Honey’s back leg and pulled her closer and up, dragging the mare’s ass with her as she rose up to two legs. Honey was quick to realize what Berry wanted and hooked her other leg around the alchemist’s barrel, helping to hold herself in place while Berry steadied herself with a hoof on the basement wall. Honey was on her back, ass and back legs in the air, Berry standing over her, already stuffing more oversized mare-cock into the slender mare’s cunt.

Berry held onto Honey’s other leg with her spare hoof and began fucking the mare in earnest. Every thrust of her hips rammed her cock farther and farther into the cute mare. Honey moaned and bit her fetlock as her belly bulged with a clear outline of Berry’s cock. She could feel every inch of it as it plunged deeper into her, deeper than Sweet or any toy had ever gone. She wasn’t some size-princess, but good fucking Celestia she could understand why some mares were.

Berry panted, sweat matting her sides as she battered the head of her dick against Honey’s cervix. Her fat balls bounced against the floor and Honey’s ass, churning and clenching as they begged to release their heavy load of cum converted Sweet Heart right into his sister. Berry knew she couldn’t last much longer, but she didn’t want to stop, trying to carefully edge herself to milk every second of pleasure she could. She was almost annoyed that, in spite of the mare’s clear enthusiasm, Honey hadn’t cum yet. Not that Berry cared, beyond some sense of pride.

That was swiftly put out of Berry’s mind along with just about every other thought as she felt pressure building in her groin. The point of no return sped past as she broke through the barrier of Honey’s cervix and used it like a cock ring while fucking the mare’s womb properly. Berry could hear Honey’s moans, but they were distant and unimportant. The alchemist’s cock bloated further as her urethra bulged, the first hot load of spooge coming up her dick like a cannonball.

Cumming felt like a cannon going off too. Berry could swear her dick pushed back with the force of her first cumshot. Honey’s belly bulged out as the high-pressure shot of foal batter filled her womb to near bursting in an instant. More cum came, shooting back out Honey’s pussy from the sheer pressure. Berry pulled out of the mare’s thoroughly creamed cunt, her cock never pausing in its steady rhythm of shooting one belly bursting load after another.

Berry dropped Honey’s legs, letting the mare lay flat on her back. But she didn’t leave her alone, poncing on the mare once more. They were belly to belly, Berry spooge-spewing cock sandwiched between them. Berry forced the side of the flared head against Honey’s lips, muffling the mare’s moans. She came at it from the other side, kissing the mare around her own cock as it drenched the both of them in Sweet Heart flavored jizz. Although Honey got the Alicorn’s share of it, naturally.

Berry pulled away from the obscene kiss, her hips humping against Honey almost automatically. She pressed a hoof against her cock, forcing the head into Honey's mouth, forcing her to swallow one mouthful of her brother after another. Honey swallowed hard and fast, perhaps understanding that if she faltered she could very well drown. She might have if Berry’s orgasm hadn’t then tapered off, her balls shrinking down to merely the size of grape fruits as she milked the last of her load onto Honey Heart’s tongue and face.

Berry let out a rattling sigh, stumbling back as her cock went soft, drooping under its own weight, dripping jizz onto the stone floor. Honey swallowed thickly as gasped, sucking down her first lungful of air in nearly a minute. She was an absolute mess, her middle swollen, womb and belly filled to the leaky brim with cum. More of it was splattered over her entire body, painting her entirely white. The mattress beneath her was in just as poor a state, soaked completely through, squelching whenever Honey shifted her weight even a little.

Berry panted and smacked her lips. Even with a few mouthfuls of her own cum in her belly, she still felt absolutely famished. And thirsty. She felt like she could drink the river outside dry. Still, she needed to tend to something else first.

Honey Heart and the mattress were both a mess, but Berry was too worn to care and she suspected Honey was much the same. The alchemist did at least pull the candymaker up onto the mattress proper, putting a pillow under her head. She then picked up the shackles connected by chains to the wall behind the mattress, pulling them over to Honey. Berry clasped the manacles around the mare’s back legs. They were padded so she didn’t hurt herself, but snug so she couldn’t get them off either.

Confident that her new and mostly willing test subject wouldn’t go wandering off any time soon, Berry stumbled towards the stairs on shaky legs. She was going to go hose herself off and then go absolutely annihilate her pantry cupboard. She had a few jugs of that sweetwater they imported in from Vanhoover she had been saving for a special occasion...
