Chapter 1

“Nooooooooooo!!”

A loud scream of denial and sorrow sounded through the hospital after a certain pink pony got the results back from her fertility test.

“I’m sorry, miss, but it’s true,” said Nurse Redheart, trying to comfort her patient.

Pinkie started crying at the news, her mane drooping down, “So I won’t be able to have a foal, ever?”

“No, you won’t,” replied the nurse, looking sympathetic towards the pink mare.

Pinkie was laying down and sobbing at this point, and looked like she was trying to melt into the floor along with her white tank top and light blue skirt. Redheart then realized that was exactly what was happening and interrupted it before it went too far. “Um, miss?”

The party mare sprang back up into solid form and launched nearly into the ceiling before she landed on the floor, looking wide-eyes at the nurse. “I have an idea.”

“You do?” Redheart asked, cocking her head to the side in confusion.

“Yes I do,” Came Pinkie’s reply before she turned around and exited the hospital room calmly.

Pinkie Pie was walking down the path to Zecora’s hut in the Everfree Forest, glancing around her at the trees, looking rather spooky given the dim lighting of twilight washing over them. Normally, something like this would’ve made her run away screaming out of terror, but she resisted the urge to do that now, as she knew this was the only way for her to have a proper foal.

When she finally arrived at the hut and opened the door, she was met with an enthusiastic greeting by the owner.

“Ah, hello, Pinkie Pie! How are you doing at this time?” Zecora begun before she saw the sadness on Pinkie’s face. “Are you alright? You’re usually full of delight.”

“No,” The pink mare responded with a bit of sorrow, “I just found out I’m sterile.”

The zebra immediately knew why her friend was so sad, remembering that she was very eager for a foal and all of the...activities she would get up to to try and fulfill that wish. “And I suppose that is why you came to me, to help you get a foal, or perhaps three?”

Pinkie nodded, “Yes, do you have something for that?”

Zecora smiled, “Yes, I do,” She said before going over to one of her shelves and grabbing a potion. “This potion will help you.”

The pink pony became eager and looked at the potion in awe and excitement as the zebra brought it over to her. It was decently sized glass vial, containing maybe around 100 millilitres of bright orange liquid. “This shall be drunk to make you fertile, but you must be careful. It is to be used in moderation, with 10 ml before each recreation, or else you will suffer immobilization.”

Pinkie took the potion from Zecora and carefully put it in her mane before eagerly hugging her and saying, “Thank you, Zecora! You have no idea how much this means to me!”

“I believe I do, Pinkie. But you should not be so carefree; to you that potion means a lot, does it not?”

“Oh, don’t worry, nothing’s ever broken in my mane before!” The pink mare said before pulling away and walked to and out the door, ending their conversation enthusiastically with “See ya, Zecora!”

Pinkie closed the door to her room at Sugarcube Corner and pulled out the potion from her mane. She eyed it eagerly as she sat down on her bed, thinking about what to do next. “Okay, so who should I get for this special occasion?” She thought while looking up and putting a hand on her chin in a thoughtful pose. “Soarin’? No. Thunderlane? No...” She squinted her eyes, trying to think of who would be best for this. “Maybe Big Mac? Mmmm no...” She asked herself before she returned her gaze to the orange vial in her hand.

“...A taste couldn’t hurt, right?” The pink pony questioned. “Eh, why not?” She shrugged and uncorked the vial and held it up to her muzzle, sniffing to find the potion smelled rather sweetly of flowers. She then opened her mouth a bit and tilted the vial slightly into it to take a taste of the liquid. Her eyes opened wide as she tasted the incredible sweetness of it, tilting the potion to drink more of it, completely enthralled by the taste, only stopping when she felt the absence of the liquid on her tongue.

She pulled the vial away from her muzzle to realize she accidentally drunk the entire potion in one sitting. “Oh... oops!” She said to herself before remembering Zecora’s words on drinking more than she was supposed to and became slightly worried. However, she was far more worried with getting someone to screw her before the potion ran out. “Oh no! I gotta get somepony now! I gotta-” She stood up, but was interrupted by a warm feeling in her chest. “Oh, is that the potion? I really have to hurry now!”

Pinkie started towards the door as the warmness in her chest expanded quickly to encompass her breasts. She put her hand on the door handle and felt the warm sensation tingle the surface of her breasts, making her feel very aroused. She turned the handle as she moaned, the pleasure coming from the potion disrupting her thought process.

The party mare put her other hand on the door frame to keep her balance as she realized she couldn’t go out like this. She rested her forehead on the door, trying to form a coherent thought. “What is happening?! And why does it feel so goooood~” She moaned and felt her tits brush against the door.

She felt the pleasure rise as she leaned her chest into the door, squishing her breasts and rubbing her nipples on it through her shirt and bra. She took her hand off the handle and put it on the frame opposite her other hand, and begun shoving her boobs into the door and rubbed them up and down, causing her to moan louder.

“Mmf... so sensitive...” Pinkie said as she started panting from the pleasure. She then pulled away from the door, taking her hands off of it and placing them on her breasts, creating a sudden burst of euphoria and forcing her head to crane upward. She massaged her tits, pressing her hands into them, rolling them around, and squishing her middle and index fingers into her nipples. She became more forceful with her breasts, making her moans louder and higher pitched as her knees started to buckle.

The fabric in front of her boobs quickly became too resisting for the party pony, so she slipped her hands down onto the hem of her shirt and pulled it up to her bra and grabbed that as well before pulling both up and onto her sizable breasts. She then started groping them with renewed vigor, only pausing momentarily when the pleasure became too much for her legs and she fell onto her back.

She closed her eyes to fully take in the feeling of her breasts being so roughly handled before she slid one of her hands down her belly and beneath her skirt to start massaging her sex as well, her arm pressing into the front of the mammary she just released. She moved her panties to the side and felt her pussy frothing with juices before she stuck her middle two fingers into it, once again causing a spike in pleasure.

Pinkie then started moving her fingers out of and into her cunt while her elbow rubbed into her nipple, eliciting even louder moans from her. She moved her hand with more force and speed, slapping her labia with the fingers outside of her pussy, the amount of which decreased as she attempted to maximize the pleasure she was feeling.

The pink mare next took her nipple between the fingers that were pressing on it and squeezed them together, forcing a small stream of milk from it. She felt the milk and lifted her breast up to her mouth as she lowered her muzzle down to meet it, stuffing the nipple in her mouth and starting to suckle on it. She tasted the sweet milk as she moaned into her tit causing it to vibrate, heightening her pleasure even further.

Her moaning was reaching a fever pitch as she was slamming four fingers into and out of her sex, rubbing against her G-spot and slapping her clit with her palm. Her pussy then began to clench on her fingers as she came, releasing a copious amount of juice onto her hand and squirting even more milk into her mouth while she let out a muffled squeal of pleasure.

Pinkie pressed her hand into her cunt and feverishly rubbed her G-spot and clit, trying to lengthen the orgasm as she squeezed the breast in her mouth with her other hand to force all the milk she could out of it. She swallowed the milk as fast as it came, further muffling her sounds of delight. Her other breast was also squirting milk at this point, and coated the back of her arm while it twitched in pleasure.

Her orgasm begun to die down, spraying less liquid out of her pussy and tits and moaning not quite as loud, which quickly turned into panting as she pulled her mouth off her mammary. She eventually stopped cumming and lactating, putting her arms to her side to relax. She then basked in the afterglow of her most powerful orgasm to date for a few minutes before noticing the weight on her chest was heavier than usual. The pink mare looked down at her breasts and gasped when she saw the reason why.

“Oh my goodness! My boobies got bigger!” The pink mare shouted enthusiastically as she moved her hands to touch them.
“Oh!” She moaned, “And still so tender~”

She sat up and then got to her hooves to continue to revel in her larger boobs, now nearly a G cup, jumping around and letting them smack against her belly while verbally celebrating loud enough to not hear the door opening and the light gasp thereafter.

“P-Pinkie?” The pony at the door said, causing the party mare to spin around to face them, revealing the pony to be a very flustered-looking Fluttershy, wearing a conservative green sweater and long maroon skirt.

“Oh hi, Flutters!” Pinkie said as she ran over to her friend and hugged her tightly, pressing their busts together, the pink one slightly larger. “What are you doing here?”

The yellow pegasus inhaled deeply in an attempt to calm herself before replying, “I-I came to check on you, actually. Rarity said she saw you acting kind of strange earlier today...”

“Oh!” Pinkie pulled back just enough to look at her friend’s face, “Yeah, I went to the hospital to check if I was fertile and I found I wasn’t, so then I went to Zecora to get something that would fix that, but I kind of drank too much of it and now my boobies are really big!”

“Umm... I-I noticed that last part...” Fluttershy responded, looking down at the pink pony. “But, are- are you still sterile?”

“I don’t know!” The other mare said, slightly squinting her eyes in thought, then gasping, “But, you know what I do know?” She added with a slightly sultry tone.

“W-what?” The pegasus asked, partially scared and partially aroused, before getting a fuchsia-colored nipple shoved into her mouth.

“They taste really good!” Pinkie answered with enthusiasm to which Fluttershy looked at her in slight confusion. “The milk does anyway. Not to say that don’t taste good to begin with, but- oooooohh~” She moaned as the mare on her mammary suckled slightly from it as a test, finding it to actually produce very good-tasting milk, and started to fully suckle to get more milk.

The party pony put her hand on the breast that wasn’t being milked, and begun caressing and kneading it, pinching her nipple to squirt more milk from it before she shoved it in her own mouth. She then reached her other hand down past her skirt and rubbed her clit in circles with her middle two fingers through her panties, make her moans louder and more frequent.

Fluttershy got even more aroused listening to her friend’s moaning, starting to rub her thighs together while suckling harder on the teat in her mouth while squeezing it with both hands, trying to force as much milk out as possible. Pinkie’s pleasure spiked at that as she slid her panties to the side of her sex and plunged her four main fingers into it. She slapped her palm against her labia repeatedly and forcefully rubbed her G-spot, her juices flowing down her inner thighs.

The pegasus took one of her hands off of the pink breast she was nursing from and slid it to her pussy to rub it through her skirt, stopping after a few seconds to lift it up and pull her panties down her thighs a little to get better access to her sex. She slowly pushed her middle finger into it, savouring the pressure and letting out a long moan. She then started sliding her finger into and out of her cunt, slowly picking up speed as she continued to drink the milk flowing into her mouth.

Both mares kept guzzling the sweet-tasting liquid coming out of Pinkie Pie’s breasts while other liquids kept streaming out of their pussies, the yellow one getting more fingers inserted into it as time went on. The milk production of the pink mammaries shot up as their owner came, beginning to squeal and her pussy gushing fluids onto the floor. The increase in milk flooding into and overflowing Fluttershy’s mouth spiked her arousal, making her cum as well.

For nearly a minute they were in that position, squealing out of pleasure while sucking the milk out of Pinkie’s boobs and spraying their sex juices on the floor, before they came down from their sexual high and fell onto their backs, panting.

“So, how was that?” The pink pony asked.

Fluttershy took a few seconds before she responded, “That was... amazing...”

“I know, right?” Pinkie said, sitting up and looking up at her friend. “I think it was these babies that made it so much better!” She continued, caressing her breasts, “And you too; I mean, you’re so hot with those huge tits and with how shy you are about them just makes it so much hotter and mmmmmm~” She moaned, now kneading her boobs and pinching her nipples.

“Uhm... Pinkie?” The yellow mare said as she sat up, getting the mentioned pony’s attention.

“Yes?” She asked huskily, still lightly pleasuring herself.

“Umm...” Fluttershy started, having to audibly gulp before continuing, “I-I think your breasts may have gotten bigger...”

“Well, duh! Obviously they weren’t this size earlier today,” Pinkie said, looking down at her tits and gasped. “Oh my gosh, you’re right! They’re even bigger now!” She shouted excitedly, jumping over to tightly hug her friend. “Thank you, Flutters!”

The pegasus lightly returned the hug, replying, “F-for what?”

The other pony pulled back, looking at her. “For making my boobies bigger, silly!” She answered, adding, “Well, again, at least...” She took her hands off of her friend and lifted her breasts with them and asked, “but do you want to make them bigger again again?”

Fluttershy gasped in realization of what she was implying and pulled her hands away, quietly responding, “Um, no, I have to go feed my animals...”

“Aww... can’t they wait?” Pinkie asked, her mane slightly drooping.

The yellow mare stood up, looking down at her friend with her new, huge bust. “Umm... n-no...” She said, backing towards the door.

“You sure?” The other mare replied, getting to her hooves and cocked her head slightly while looking at Fluttershy.

The pegasus bumped into the door, grabbing the handle and turning slowly, quietly answering, “Y-yes...” before she threw open the door, quickly ran through it, and slammed it close.

Pinkie stared at the door for a few seconds, listening to her friend leave, then said to herself, “Oh well! Guess that means I have to make my boobies bigger again again by myself...”

Chapter 2

Twilight Sparkle was sound asleep in her bed at Golden Oaks Library, the dim light of dawn peeking through her windows and lightly illuminating her body, tucked under her dark blue covers spotted with white specks representing stars. She slept with quiet breaths as a knocking sound came from the main room, but not loud enough to stir her. It did, however, stir a purple and green dragon who was asleep on a small mattress next to the larger bed.

Spike sat up and shook his head to clear his mind from the sleep as he heard the knocking again. He looked over to the window to see the very early sunrise and wondered who or why somepony would be here that early before standing up and moving over to the edge of Twilight’s bed, putting one of his claws on her shoulder and shaking her lightly.

“Hey, Twilight,” He said quietly, trying to slowly rouse the mare, “Wake up.”

“Mmm, five more minutes...” the unicorn sleepily replied, shifting her position a little.

“Hey, no, you gotta wake up, somepony is at the door,” Spike responded, lightly shaking her again.

Twilight finally awoke and looked at her assistant, sleep still clouding her mind as she groggily asked, “Wha?”

“Somepony is at the door,” The dragon repeated as he let go of his friend.

The lilac mare gasped as her pupils turned into pinpricks before she kicked off her covers to reveal her purple pajamas dotted with yellow stars as she hopped off the bed and began to run over to the bedroom door, but was stopped when a scaly purple hand grabbed her own.

“Hey, relax!” Spike said with light worry. “I just wanted you to be awake, you don’t need to run downstairs like this,” He indicated her frazzled mane and unprofessional clothing, “I’m sure whoever woke you up at this time can afford to wait a couple minutes.”

“Yeah, but if they’re here now, it’s gotta be really important!” Twilight hastily reasoned, pulling her hand away from her assistant’s and opening the door, rushing through to go to the door of the main room.

“Dammit...” The dragon sighed, rubbing the bridge of his muzzle in irritation.

The unicorn, meanwhile, reached the floor of the main room and crossed it at speed, nearly slamming into the main set of double door as she took hold of one of the handles and swung the door open to see a very big-breasted Pinkie Pie waiting impatiently on the other side.

“Hey, Twi!” The party pony said as she jumped on the other mare, hugging her tightly, pressing her nearly I-cup boobs into her friend through her heavily strained and revealing tank top.

“H-hi Pinkie...” Twilight responded, blushing heavily as she looked down to see the massive tits pressing into her much smaller chest. The pink mare pulled away from her friend, allowing her to see the huge pink pillows nearly bursting out of her top. “Um...” The librarian started while continuing to stare at her friend’s chest.

Just then, Spike emerged from the bedroom wearing a black t-shirt and blue jeans, walking tiredly over to the stairs and stopping at the top step as he looked to Pinkie and saw her gigantic tits. He stared in utter shock and arousal at them, his mouth somewhat agape and a large boner tenting his pants.

“Hey Spikey!” Pinkie said enthusiastically while waving to the dragon, who was completely unable to respond because of the sight of her massive breasts.

Twilight closed the door behind her friend with her magic, her cheeks still flushed from arousal as she looked back at her friend’s face and shyly asked, “Um, what brings you by?”

“I wanted to talk to you about something, actually!” The party mare responded energetically, her focus returning to the unicorn.

“Uhm, about...” The purple pony pointed to Pinkie’s oversized chest, “That?”

“Kind of! Can I?”

Twilight squinted her eyes in confusion as she looked at her friend. “Um, sure. I mean-” She was cut off when her friend grabbed her hand and dragged her up the stairs and into the bedroom, passing by Spike, who tried to follow their movement and managed to catch another glimpse at Pinkie’s massive mammaries before the door to the bedroom was slammed shut, leaving him to stare at it with complete awe and arousal.

Pinkie threw herself onto Twilight’s bed, her huge tits resting on her front as she looked over at her friend standing awkwardly by the door.

“Come on, Twi! The bed’s warm!” The energetic pony invited, spreading her arms out as if awaiting a hug.

“Um, I thought you were here to talk, not have sex...” The unicorn responded while she turned her head to the side in embarrassment.

“Oh, don’t worry, we’re not going to have sex,” Pinkie replied calmly, but added in a sultry tone, “Yet.”

The other mare’s blush became brighter at that before she started to slowly walk over to her friend, her hands clasped together right above her crotch. She then sat down on the edge of the bed, looking over at the party pony and trying not to focus on her tits.

“Um, so what did you want to talk about exactly?” Twilight asked while attempting to remain calm.

“Well, I went to the hospital and found out I’m sterile,” The pink mare said nonchalantly, making her friend slightly confused. “But then I went to Zecora to get something to fix that, and it did this to me!” She continued, picking in her breasts up raising them a bit as if to present them.

“I don’t think fertility potions are supposed to do that...” The unicorn responded, her blush fading a little from the confusion.

“Yeah, well I drunk maybe a liiiiiittle too much...” Pinkie replied and took her hands off her chest, having one of them portray a short distance between two fingers.

The other pony furrowed her brow at this. “How much?” She asked flatly.

“Umm...” The party mare looked at the ceiling for a few seconds while she did the math in her head. “Ten times?” She said, putting on an innocent smile.

Twilight opened her eyes wide in shock at the statement before pouncing on her friend, shaking her vigourously by her shoulders, frustratedly screaming, “Dammit, Pinkie! What have you done!?” The shaking sent the other pony into a giggling fit and made her boobs bounce all over the place, forcing them out of her top which allowed them to occasionally scrape against the purple mare’s chest.

The unicorn eventually stopped shaking Pinkie and stared at her intently, although somewhat distracted by her friend’s jiggling tits and how discombobulated she got from it. The pink pony’s giggling died down, allowing her to disorientedly say “But it tasted so gooooood!” as she fell forward onto her friend, pressing their busts together.

“Pinkie?” Twilight asked in slight concern. The other mare responded by pressing her tits into her a little harder. “Pinkie?” She asked again, though now with confusion and arousal, to which her friend pressed her breasts even harder into her. She then felt a light trickle of liquid come out of the nipples that were completely squished against her chest, making her shout, “Pinkie!”

“Hmm?” The pink mare asked and looked up at her with slight lust in her eyes.

“Are your breasts producing milk?” The unicorn asked, slightly bewildered by the liquid she felt seeping into her top.

“Oh, yeah!” Pinkie responded, pulling back from her friend and raising one of her massive mammaries with her hands to show the milk oozing from its nipple. “Want some?”

“I, uh...” Twilight started, but was cut off by the leaky nipple getting shoved into her mouth along with an exuberant “Here you go!” from its owner. She then tasted the milk and found it to be really sweet, but not overly so. It was so good, she had to have more. She suckled from the breast, pulling more milk from it and having it flow across her tongue to get another taste of it, which only empowered her sucking further.

“Heehee!” The milky mare giggled. “You like my milk, Twi?” She asked mirthfully, to which she received a subtle nod from the milk-enthralled unicorn. “Well, I do too!” She said as she lifted her other breast up to her own mouth and began to suckle from its nipple, drinking some of her own milk.

Pinkie then started to moan as her friend grabbed the boob in her mouth with both of her hands and started to suckle harder, drawing more milk from it. The busty pony then did the same, leaving both mares to nurse heartily from the pink mammaries trapped between them for multiple minutes.

Twilight eventually broke off though, panting for air and rubbing her belly, which had expanded somewhat from how much milk she drank. The other pony then did the same, but giggled gleefully when she felt her belly.

“Look, Twi! My belly’s so big now!” Pinkie ecstatically exclaimed, patting her milk-filled belly as if to show what she was talking about.

“Y-yeah...” The unicorn panted, “But these are still so big...” She finished while grabbing the still huge breasts before her with both hands.

The other mare moaned at the touch, arousing Twilight and causing her to stare at them for several seconds before a surprised gasp came from the pink pony as she felt something press into her sex, making her stare at her friend with shock for a moment before saying, “I didn’t know you had a dick!”

The purple mare’s cheeks flushed brightly while she pulled her hands back and looked shyly to her side at that. “Y-yeah,” She responded, “I was just doing some experiments and I couldn’t reverse this...”

“Did you mean to give yourself a dick?” Pinkie asked, confused as to what type of experiments she was doing.

“Um, yeah,” Twilight said as she looked back at her friend, “I just wanted to make something that could overcome your low fertility...” She received a confused look from the other mare and elaborated, “Most ponies aren’t completely sterile, so I thought you just had low fertility...”

The pink pony gasped at that, and a moment later pounced on her friend, hugging her tightly. “Aww, thank you, Twi!” She elated while not noticing her breasts pressing into the unicorn made her even more aroused. “Thank you for trying to help me get a foal!”

Twilight took a couple seconds to adjust to her current situation before huskily responding, “Um, Pinkie?”

Her friend pulled back just enough to look the lilac mare in the eyes and tilted her head a bit. “Hmm?” She then felt the stallionhood press slightly harder into her nethers and realized what her friend was talking about. “Oh, you need some help with that?” She asked while she started to rub her sex back and forth.

“Guhhh...” The lavender unicorn groaned from the pleasure, her hands grasping at the covers of the bed.

“Oh, you do!?” Pinkie replied jovially. “Well, just let Auntie Pinkie take care of it!” She said while taking hold of her friend’s shoulders and pushing her backwards to lay down. She then slowly slid her hands down the lavender mare’s chest and belly, reaching the hem of her pants and moving her fingers under it and sensually added, “Let’s see just how big this monster of yours is!”

The energetic pony then pulled the pants down quickly to unveil Twilight’s stallionhood, getting slapped in the face by it as it sprung up. It then stood nearly perpendicular to its owner’s body, the other mare resting her face against it as she stared at it, taking in its nearly half-meter length and around 7 centimeter diameter. She grabbed the violet-coloured shaft and pressed it slightly harder into her cheek, beginning to drool while she slowly rubbed her hands up and down it.

“P-Pinkie...” The purple unicorn moaned, eyes fixed to the huge-breasted pony rubbing her shaft as she panted with arousal.

“Hm?” Pinkie asked, breaking from her stupor and looking back at her friend’s face.

“M-more...” Twilight panted out. “U-use your boobs...”

“Oh, my boobies?” The party pony responded, grabbing her massive mammaries and holding them up as if to present them. “Sure!” She added eagerly and plopped her breasts on either side of her friend’s cock and pressed them together and ended up covering most of its length. She then moved her boobs slowly up to cover the top part of the stallionhood before pushing them back down to their original position.

Pinkie next stuck her tongue out of her mouth as she moved her muzzle closer to the flare of her friend’s shaft, starting to lick down the bottom-side of it when her tongue made contact. She didn’t get very far though, as her breasts sliding up and down the cock kept blocking her, so she moved back up to the tip and enveloped it with her mouth. She popped the flare out after a moment when she licked across the tip and tasted precum, then started to move her mammaries across the shaft quicker to make it produce more.

“Pretty tasty, Twilight!” The pink pony giggled as she looked back up at her lust-enthralled friend, who merely nodded lightly in acknowledgement. She wrapped her mouth around the stallionhood again, though this time for longer as she licked the tip repeatedly to taste more of that sweet precum before eventually beginning to press her muzzle down onto the shaft, forcing more of it into her maw.

Pinkie pulled her hands off her breasts as she moved her mouth down to make contact with the top of her tits, pressing her hands onto Twilight’s thighs to steady herself as she started to bob her muzzle up and down the top part of her friend’s shaft, making the unicorn’s pants turn into moans. When she found a steady rhythm, she moved her hands slowly up the other pony’s thighs and coming to a stop at her huge balls.

She cradled her friend’s dark purple balls, both a bit bigger than a peach and brimming with voluminous amounts of seed, lightly caressing them as she continued to thrust her muzzle up and down the cock shoved into her maw, now slightly faster. She then squeezed her friend’s plump balls, making the lavender mare’s mind go blank and let out a loud moan from the pleasure.

The enthusiastic pony sped up once again, nearly becoming a blur as she loudly slurped along the huge cock in her mouth and kneaded the balls below it to maximize the pleasure her friend felt. She continued tasting the precum coming from the stallionhood and it flowed freely into her mouth, reveling in its sweet taste for a while until she felt the well-endowed unicorn tense up, signalling she was about to cum.

Pinkie then quickly put her hands back on her friend’s thighs and pulled her head off the shaft, which made a lewd popping sound when the flare exited her mouth. She frantically blurted “Wait!” as she hopped on top of her friend and stuck a hand below her skirt to pull her thoroughly soaked panties to the side of her frothing sex, then pressed said sex to the tip of her friend’s shaft. She pushed her pussy downwards, not taking much force to pass the flare because of the excessive lubrication, both mares moaning loudly as she kept going until she hit the medial ring.

The ponies’ moans turned into screams as they came, the purple one injecting her seed into her friend’s cunt, which sprayed its juices all over and around her cock and balls. The cum splattered into Pinkie’s womb, its sheer volume slowly beginning to visibly distend her belly after several seconds. Her belly kept expanding as the mares kept cumming, taking more than a minute for their orgasms to start to die down, and even longer for them to stop completely, at which point the party pony fell over onto her friend’s chest.

They both then laid there with only their heavy panting breaking the silence for multiple minutes before Pinkie spoke up. “So now, I should be pregnant?” She asked tentatively.

“Uh,” Twilight started as she looked at her friend. “No, I haven’t figured out how to make the sperm fertile yet...” She admitted in a slightly defeated tone.

“Awwww... but I wanted to have your foals!” The other mare replied, somewhat saddened as she wrapped her arms around the unicorn and hugged her.

The lilac pony returned the hug tiredly, responding, “I know, I just need some more time to figure it out...”

“And then when you do, we can have sex again and I’ll have your foals!?” Pinkie asked hopefully as a smile came to her face.

The unicorn lightly chuckled at her friend’s enthusiasm, then replied, “Yeah... I guess...”

“Yay!” The pink mare shouted as she jumped off her friend. “Okay, I’ll see you then!” She said, bouncing over to the door and opening it.

“Wait, Pinkie!” Twilight yelled towards the other mare while quickly sitting up, but the pink pony had already hopped through the door and closed it, completely naive to her clearly-just-had-sex appearance and smell. “Dammit...”

Chapter 3

Rarity was hard at work in her Boutique, working on a dress for her new summer line of clothes. Shallow light scattered through the windows of the second level of her shop onto the desk she was working at, illuminating her white, short sleeve blouse and dark orchid skirt with the maroon and mauve of the early morning sun. She adjusted her bright red glasses as she continued working, the room silent but for the thrumming of the sewing machine and the muted cacophony of sounds emanating from outside. At least that was until a quick few knocks came from the main entrance.

She quickly turned off the sewing machine and made her way to the main room, knowing that one of her friends or clients must be at the door, being how the shop wasn’t open at this time. She exited her work room and trotted down the stairs and called out “Coming, dear!” before approaching the main door and opening it to reveal... Pinkie Pie. Though something seemed a bit different about her, not her oversized grin nor her extremely vibrant pinkness, neither her poofy mane or tail, no, it was... her tits.

Rarity found herself quickly enthralled by their size, their plumpness and light sag implying the monumental amount of milk inside of them. The nipples that sat upon them stood firmly erect, at a heavy contrast to the immense softness and give the rest of the breasts would have. She stared at their splendor for an unknown duration, so powerful was her reverie that her sense of time escaped her, but was eventually brought back to reality by the ministrations of her friend.

“Rarity?” Pinkie said, getting the other mare’s attention.

The unicorn shook her head to clear her thoughts before responding, “Ah, sorry darling. I just wasn’t expecting... that.” She looked back up at her friend’s face and backed away from the doorway before adding, “Please, come in.”

The pink pony bounced inside, her breasts following suit, yet in a much wilder manner. Rarity found herself staring at them once again, entranced by their movements and the sounds produced thereby, having to practically tear herself away from their sight before closing the door and looking at her busty and bombastic friend’s face, actively keeping her eyes from drifting elsewhere.

“So, what brings you here, Pinkie?” She asked, the forced calmness in her voice being betrayed by the massive crimson blush covering her face.

“I need some new clothes! My other shirts don’t fit anymore,” Pinkie replied, energetic as usual.

“Ah, because of those?” The white mare responded, glancing at the other pony’s breasts to imply what she meant, to which said pony nodded vigourously. “Well, I shall need to get some new measurements. Follow me!” The unicorn said, turning around and walking to the main work room of her boutique, her friend hastily following her.

When the pair reached the work room, Rarity levitated over a tape measure, clipboard, and quill while she said, “Now then, if you would, stand still.” Her request was obliged, allowing her to pull the tape measure taught with her magic across her friend’s shoulders and record their distance apart, quickly followed by shoulder-to-hip and midriff circumference measurements. She inhaled deeply to calm her arousal before wrapping the tape measure around the other mare’s chest, then had it circle one breast in a plane parallel to the rest of her body before putting the tape away and staring at the clipboard, clearly trying to pull her thoughts away from that enormous pink bust.

“Um, so, darling,” The unicorn began, “Do you mind telling me exactly why your, ah, assets are so large?”

“Oh! Of course!” Pinkie replied before explaining, “Well, you know how I always wanted a foal, right? Well, I went to the hospital to check if I was able to have them or not, and it turns out I can’t! So I went to Zecora to get a potion to help with that, but kind of drank too much, and it made my boobies grow really big, but not this big, that only happened after Fluttershy came into my room because she told me you saw me acting really weird, so we had some hot sex, then I masturbated a bunch after she left,” She paused to take a large inhale, “But wait, there’s more; because then I went to Twilight to see if she knew why my boobies became so big, but then she showed me she gave herself a huge dick that cums gallons so she could try to get me pregnant because she thought I was only low fertility, not none, but we still had some hot sex with it and she drank a lot of my milk- Oh, I forgot to mention, my boobies can cum milk now!” She finished with an exuberant smile, grabbing her boobs and squeezing her nipples which made some milk trickle out of them.

Rarity stood in place while she listened, her blush managing to grow ever deeper as the story continued, leaving her speechless for multiple seconds afterwards, before she calmly said, “Darling?”

“Yeah, what’s up?” The other pony replied, taking her hands off her chest while leaning forward and looking at her friend with eager, wide eyes.

“Do you mind catching me? I’m about to faint,” The white mare stated before her eyes started to roll up into her head and she fell backwards, but was caught by Pinkie, who held her from the back with her chest pushed up against her friend’s back and her arms grabbing her by the waist.

Rarity woke up a few hours later, and noticed she was laying on something soft and warm, and didn’t have a headache, meaning her friend managed to prevent her from smacking her head against the floor.

“Thank you, Pinkie dear,” She thought as she opened her eyes, her vision taking a few seconds to come back into focus before she sat up, coming face-to-face with a madly grinning pink pony.

“AHH!” The snow-coloured unicorn shouted, flinging her head back into the pillow she just got up from. She took a moment to regain her bearings before sitting up again, this time staring at her friend the whole time. “Pinkie!” She yelled, making the other mare’s mane and expression droop slightly, “Don’t do that!”

“Sorry, I was just really worried about you!” Pinkie replied, seeming rather concerned while she backed away from her friend slightly. “I was just explaining how my boobies got really big and then you just fell over- but don’t worry, I caught you- then I brought you to your bed and I just sat here, waiting for you to wake up. But why did you fall over when I talked about my boobies? Does that just happen when somepony talks about their boobies to you? Or is it because you don’t like my boobies?” She finished with a look that was somehow both crestfallen and excited.

“Your breasts are fine, darling,” Rarity responded, lightly blushing from the topic. “I just fainted because that’s not all you were talking about,” She added calmly.

The bombastic earth pony paused for several seconds while she thought, before gasping loudly and exclaiming, “Oh yeah! I was talking about the-”

“Shush, dear. I get it,” The other mare said after pressing a finger across her friend’s lips to silence her. “Regardless, I suppose you can leave now that I have your measurements. Well, unless there’s something else you want to talk about...?” She added, placing her hand back at her side.

“Yes, actually!” Pinkie responded energetically while she grabbed her boobs with her hands again. “Do you want some milk?”

Several seconds passed in an awkward silence before the unicorn finally said in a rather nonplussed tone, “Pardon?”

“I told you that my boobies can make milk!” The other pony replied while squeezing her nipples and letting some milk trickle out as if to show what she meant. “Do you want some of it?”

Rarity gasped in realization before heavily blushing and looking away from her friend in embarrassment. “I... I suppose I am a little intrigued...” She said timidly after a few seconds.

“Great!” Pinkie responded and waited until the other mare looked back at her before shoving one of her leaky nipples into her white lips.

“Mmph!?” The fashionista yelled, although muffled by the nipple stuffing her mouth, while she took hold of the breast it was attached to and tried to pull it away. Her protests quickly died however when she tasted the milk, finding the flavour lovely despite (or perhaps because of) how sweet it was, now using her grasp on the mammary to knead and force more milk from it.

Her efforts proved fruitful, as the flow of milk did somewhat increase and quiet moans of pleasure began to emanate from the mare whom it came from. However, all sense of anything outside faded away as her mind became awash in the pleasurably addling taste of the milk. She became only able to taste and feel it sloshing around in her mouth before quickly swallowing, as well as feel the bulbous and soft nipple sitting on the round and plump breast it came from on her lips and between her hands.

“Mmmmm~” Rarity moaned as she continued drinking that intoxicating milk, her eyes going closed to further focus on her other senses. She kept in that position as time lost its meaning for her, her mind only able to focus on the milk flowing into her mouth as the minutes flew by. More moans escaped her lips as she basked in the lovely sensations, the vibrations they incited only increasing the flow of milk further.

It did come to an end though, as the lack of air eventually got to her, making her audibly pop the nipple out of her mouth and start panting heavily, trying to regain her breath while her senses came back to her. She leaned back against the bed, using an arm to prop herself before looking back at her gleeful friend.

“Like that, did ya?” The pink pony she was nursing from asked mirthfully, her words followed by giggles.

“Umm,” Rarity started before swallowing, “Yes, I very much did.” She started to feel a somewhat uncomfortable sensation in her belly, making her look down at it and notice its now rather pronounced shape, which made her look multiple months pregnant. “Oh no! Pinkie!” She exclaimed at the sight.

“Is everything alright?” Pinkie replied, sounding slightly concerned at her friend’s hysteria.

“No! Don’t you see!?” The other mare responded, putting a hand on her pudge and slowly rubbing it while she sat up. “This is unacceptable! This will ruin my fashion career! If anypony sees me like this, they’ll laugh at me for being obese and... and-”

“Hey! Stop thinking like that!” The bombastic earth pony cut her off. “Nopony is going to make fun of you!” She said while putting her hands on her friend’s shoulders and looking in her eyes to try to keep her calm. “And if anypony does have a problem with it, they can stuff it! What you look like is your own choice and they have no say in it!”

Rarity looked back into the other mare’s cool blue eyes, somehow finding calm in them despite the pony’s eccentric nature. “Yes, I suppose you’re right...” She responded quietly before drawing her gaze back to her large belly. She rubbed absentmindedly with her free hand, occasionally wincing, but eventually added, “Erm, I do still find this rather uncomfortable...”

Pinkie looked at her friend for a few seconds before gaining an ecstatic grin and asking, “Want a belly rub?”

Many awkward seconds passed while neither pony moved apart from the light intakes and exhales of breath between them. The heliotrope-maned unicorn eventually looked back up at the idiosyncratic mare before her with a blank expression and blinked.

“What?” The fashionista said flatly, utterly vexed by the offer.

“I can rub your belly, and it’ll make it more comfortable!” Pinkie explained.

Rarity cocked her head and showed a rather prominent blush that said she wasn’t entirely comfortable with the prospect of somepony touching her in such an intimate manner. “Um, well...” She started, glancing down at her pudge, “I-I suppose it couldn’t hurt...” She finished as she looked back up at her friend’s grin, which became even wider at the acceptance.

The pink pony then took her hands off the unicorn’s shoulders, but quickly moved them to the sides of her torso, lightly pressing into the thin white fabric surrounding it. Her eyes became focused on the big distension visible through the blouse as she slid her hands across it, meeting in the middle on its zenith. She next moved her hands downward to the hem of the shirt, lightly gripping it and looked up to her friend’s face for approval.

The white mare lightly nodded, allowing the unusually calm earth pony to slide her fingers up to one of the buttons of the shirt, then deftly undo it. She stuck her tongue out while she focused her gaze on the buttons, swiftly undoing them one-by-one up to the one right below the bosom, when an alabaster hand grip the pink pony’s, making her stop immediately and look up at the unicorn’s face.

“Now, now, deary. This is supposed to be a belly rub, not a breast groping,” Rarity reminded her friend, making her look up apologetically at her before lowering her hands down her belly, lightly pressing into it after gliding down to the navel. Her fingers produced slight indents into the pudge, the incompressibility of the fluid making it bulge out elsewhere and also caused its owner to tense up a little.

Pinkie then returned her gaze to the ballooned belly as she rubbed it, moving her hands up and down slowly with moderate pressure, enough to move and massage, but not enough to hurt. Pleasant sighs were released from the big belly’s owner as she closed her eyes to bask in the feeling while sliding her hands along the bed, keeping them far apart to allow her to fully relax.

The earth pony next started to rub in circles, covering most of the white pudge with her slow, rhythmic ministrations, inciting low moans of approval from its owner. The pink hands then started to desync in their movements, taking a few seconds to become opposite in polarity, her right hand arriving just below the other mare’s chest while the other hand grazed the top of her hip.

Rarity then started to slowly tilt backwards, her back lowering down onto the soft bed, forcing the pony working on her belly to lean over her friend while she continued massaging. Multiple more minutes passed while the unicorn relaxed, basking in the pleasant sensation on her belly, similar to that of a normal massage, yet oddly arousing in a way. Perhaps it was the milk inside her belly that made it that way, or maybe it was from the location they were in- a private bedroom, where sexual things tend to happen- or it may have also been how slow and serene her friend was being, the heavy contrast from her usual bombastic nature making her actions all the more sensual. Or maybe, just maybe, it was the fact that her friend seemed to be right in front of her crotch, given the light breaths she felt on it.

Wait, what?

The alabaster mare abruptly opened her eyes and craned her head up to see where her friend was, only to see a pink, poofy mane sticking out of her skirt.

“Pinkie!” Rarity yelled, getting the pink pony’s attention, who quickly shot her head up while stopping her massage, showing that she was holding her friend’s panties in her mouth, despite clearly not having moved very far from her current position.

“Hmm?” Pinkie asked, muffled by the undergarments in her teeth.

The unicorn cocked her head slightly at the sight before closing her eyes and exhaling, then looked back at the other mare and asked flatly, “What are you doing?”

The overly-excitable pony spat out the panties and replied, “I just wanted to relax you!” A confused look was given from her friend, so she elaborated, “I know you wanted to get relaxed, and know that belly rubs are really good for relaxing, but I also know that a really really good way to relax is to have hot sex with you, because you feel really really good in the moment, and then everything after that is really really fuzzy and feels really really nice, so that way you feel really really relaxed and you can have a really really good sleep after making some really really good and sexy memories!”

Rarity looked at her friend with a blank expression for multiple seconds before she blinked and furrowed her brow, then closed her eyes to think about the offer. A rosy blush lit up her cheeks while she pondered it, and while she did debate the ethics and consequences of having sex with somepony you’re not romantically involved with, the aroused and relaxed part of her demanded that she shan’t be left in such a position unfulfilled.

“Ah, well, I suppose that makes sense,” She responded, trying to hide her very passionate interest in getting off, “So I shall allow you to go ahead.” The other mare then quickly darted back down beneath the purple skirt, but stopped when the owner of that skirt interjected, “But! I shall have you know I don’t want this to mean anything to our preexisting relationship, as this is to be merely sex, and thus has no romantic implications. Are we clear?”

“Got it, Ma’am!” Pinkie said with a salute, before once again diving back into her friend’s crotch, this time actually connecting with it.

“Oh fuck! Pinkie!” Rarity yelled from the abrupt pleasure, not able to care about the crude language she had just used, as her friend smashed her face into her labia while grabbing her thighs, quickly slithering her freakishly long tongue into her pussy. She snaked her tongue in in a sinusoidal pattern, pressing against the inside of her friend’s vagina and rubbing it as it slid further inward.

When the eccentric pony finally managed to shove her entire tongue into her friend, nearly reaching her cervix, she started wiggling it up and down in a manner that imitated what she was doing previously, but just not going further in. The unicorn was moaning unabashedly, her head thrown back and tongue hanging out in pure pleasure, while her hips thrusted up and down in an uncontrolled manner.

The pleasure the white mare felt became greatly amplified by what her friend did next; moving her tongue in a corkscrew pattern, now allowing her to lick all around the other pony’s vagina instead of just the top and bottom. The moans drowned out every other sound, filling the bedroom and likely the rest of the building with the sounds of immense pleasure as their owner’s climax quickly neared.

Pinkie slid her hands up from her friend’s thighs and down to her flanks, surrounding her hands in plushness with a bed on one side and a lovely pair of butt cheeks that she groped. The other mare’s moaning somehow became even louder from that, practically turning into lust-filled screams. She then started to massage her friend’s ass in a similar manner to how she did her belly previously, making the unicorn’s moaning waver slightly in pitch and volume, deafening though it remained.

The cunnilingus-performing mare next moved her top jaw in such a way as to graze her teeth to the now-exposed clit of her friend’s pussy. The effect was immediate; Rarity came, the juices flowing out of her pussy quickly started spraying out, her moans died in her throat as she no longer had the capacity to verbalize something so loud, and her hips stopped writhing all over the place and started vibrating on the spot. The pure ecstasy she felt pushed to greater sexual heights than she had ever dreamed of before, her mind being unable to comprehend anything for time indiscernible.

She eventually managed to come back to her senses however, her vision and hearing beyond blurry, her feeling completely numb, but they all quickly sharpened to see her friend grinning ecstatically before her while she laid down on her bed, her limbs splayed out randomly while her body was covered in sweat.

“Did ya like that?” Pinkie asked enthusiastically, her muzzle soiled in pussy juice.

The exhausted unicorn took a few moments to pant before slowly replying, “So... very... much...”

Chapter 4

“Okay, next patient... Pinkie Pie? I just had her last week...”

Nurse Redheart looked at her portfolio for the day and sighed. “Mare’s just probably in denial; she seemed very sad when I told her the news...” She let out a sharp inhale of realization, “But she also said something about ‘having an idea’... perhaps she’s coming again to test it.”

She sighed again as she sat down on her office chair, closing the folder and tossing it on her desk. “Doesn’t matter too much I suppose, there’s not much I can do for her beyond tell her if she’s sterile or not...” She leaned back in her chair and stared at the ceiling in an attempt to relax for a short while before the door to the room was opened and somepony was heard quickly walking inside.

“So, Pinkie Piiieeeee...” The nurse trailed off as she looked ahead of her at the energetic earth pony that just entered the room, though all facets of the mare seemed unnoticeable in light of the one major change she had between her visits; her breast size. The alabaster mare’s eyes became wide with her mouth hanging open and lightly drooling as she gazed upon the humongous mounds, the thin, off-white material holding them leaving the mare’s midriff uncovered with a large section of cleavage shown.

Redheart, while she was loathe to admit it, had a bit of a fetish for big breasts, and the very ones before her were ticking all of her boxes. Huge? Check. Slightly sagging? Check. Plump and soft? Check and check.

They were perfect, at least to her eyes. Their visage quickly addled her mind, making her wish only to take them in via all of her senses; to feel them, smell them, taste them...

“Reddy? Reddy!” Pinkie called, breaking the other earth pony out of her lustful reverie.

“O-oh, wha?” Redheart sputtered out as she shook her head, then looked forward to find herself very close to her patient, and even closer to her huge tits. “S-sorry... I... wasn’t expecting that...” She responded while deliberately looking away from those stupefying pink breasts to prevent herself from being lost in her mind once more.

“Oh! Yes, these!” The eccentric mare said as she looked down at her chest and placed her hands on their sides, slowly rubbing along their sides. “I got these babies from a potion from Zecora after I went here the first time!” She explained, leaving the nurse confused as to how they relate to her being here now. “Uh, only thing was, they were suppose to make me fertile for a little bit of time, but kind of accidentally drunk way too much of it at once, and it did this! But I’m not sure if I’m still sterile, so I was hoping you would check, Reddy!”

The nurse took a few moments to process that with what small part of her mind that wasn’t consumed with reveling in her buxom patient’s chest, then nodded as she replied, “R-right... well... a-as you understand, w-we will need your, um... fluids.”

“Don’t worry, I already got them!” Pinkie exclaimed as she pulled a small plastic jar filled with a translucent yellow liquid out of her mane.

Redheart looked at it for a while, first with bewilderment as to its existence, next with deadpan as she realized why, then thought as she got an idea, and finally only slightly subdued devilish lust as she fleshed it out. “I’m... not sure if that would work, Pinkie. Stale urine tends to atrophy- er, break down- the DNA with time, so we’d likely get wrong results if we were to test it,” She said, barely managing to curb the lust in her voice.

The pink pony gasped exasperatedly and she responded, “It goes stale that fast!? I just took it a couple minutes ago!” She quickly became crestfallen, dropping the jar onto the floor with her entire body beginning to sag as she added, “And I don’t have anymore in me...”

The nurse blinked as she processed that, then shook her head. “Er, no...” She started, earning an excited gasp from her patient, “I just didn’t think that you would’ve done it that recently...” She added to which the other earth pony started jumping around hysterically. “But,” She quickly interjected, making pause in the middle of the air and look at her quizzically, “While urine would normally work for a fertility test, the circumstances surrounding your current state are decidedly abnormal; so we’ll have to do this a bit differently.”

Pinkie landed on the floor and fully faced her to give her full attention. “We’ll need some of your other fluids to make this work,” The white mare continued, and getting no reaction, she elaborated, “Those being your, ah, sexual juices or your milk.” She got a reaction this time, specifically of her patient blushing somewhat, though she still looked rather confused. “Because they better relate to pregnancy,” She added, making the other mare’s confusion to subside, but not her embarrassment.

“Oh, well... my boobies have been producing a lot of milk recently, so can we do that?” The normally eccentric pony asked in a very timid manner.

“Of course,” Redheart replied, managing to restrain her lust enough to keep her voice clear of it, but an excited grin crept up onto her face nonetheless. She stood up and walked over to a cabinet on the far end of the room, and pulled a small jar out of it, quickly uncapping it and heading back over to her patient. “So, if you would,” She said, gesturing to the cloth covering the other mare’s massive mammaries.

“Right!” Pinkie exclaimed as she quickly grabbed the hem of her shirt and pulled it up over her breasts. The nurse was swiftly thrown into a reverie at their sight, the lovely pink colour and plump, weighty visage filling her mind once more. She eventually blinked, pulling her somewhat from her stupor, then closed her eyes and bit her lip while she let out a quivery breath replete with lust.

The alabaster pony began to breathe harder while tentatively reaching her right hand towards one of those captivating fuchsia orbs, eventually making contact with its upper half, a sharp inhale coming from its owner as a result. She lightly pressed her palm into the giving flesh, feeling its softness as she slid her hand down to the erect, even pinker nipple sitting atop it.

The nurse let out another shaky breath as she took the nipple between her index finger and thumb while bringing the small jar in its firing line, before squeezing it. Milk came quickly squirting out of the nipple as a light sigh of relief came from its owner, and was quickly accompanied by the sound of milk splashing in the jar, not at all helped by the lustful shaking of the mare holding it.

All of a sudden, Redheart dropped the jar and lunged for the breast, shoving it in her mouth and violently suckling on it, its owner releasing a sharp moan of pleasure that trailed into a slower one of relief. The milk blasted immediately into her mouth, and it tasted amazing. Far better than she could have imagined, but she couldn’t be bothered to think about what she thought it tasted like before as now she had it flooding into her mouth straight from the tap, completely flooding her mind with utter bliss.

Pinkie was also enjoying a level of bliss, though hers was of how lovely and arousing the powerful sucking on her nipple felt along with how happy the other mare looked. She gained a euphoric grin as she put her hands on the nurse’s shoulders and slowly slid them around her neck, pressing her slightly further into the milky mammary. She felt very relieved to get all of this milk out of her, the stress in them from having not drained them today was making them very tender, the light pain from inside combined with the pleasure from her shirt rubbing against it made her feel like she was about to explode, and probably would’ve if the other mare hadn’t taken initiative to drain them right then.

The white pony kept gulping down the luscious milk, squeezing and kneading the breast it came from to force more of into her faster, her senses null but for the delectable taste flooding her mouth and the warm, supple flesh of the breasts from whence it came. Not the passing of time nor the growing stress in her belly managed to rupture her reverie for minutes on end, only changing when the flow of milk began to ebb from how much she had already drained from its source, subconsciously allowing her to feel the pressure of her belly and take her left hand off the huge teat stuffed in her mouth and guide it to her bulging stomach. She rubbed her bloated belly absent-mindedly to help soothe the stress, but it, along with the pressure on her lungs from the lack of air, managed to eventually force her away from her patient’s nipple, taking deep breaths as she fell to lay her back onto the floor, letting her feel the outside world once again.

“Oooohhhgg...” Redheart moaned as she pulled her light grey shirt over her beyond-fully-pregnant-looking belly and begun to rub it with both of her hands, feeling very sick from all of that milk she drank.

“Oh, wow...” Pinkie commented, devoid of her usual eccentricity as she lightly panted from the pleasure and exhaustion. “You’re so big, Reddy,” She said while kneeling before the nurse’s huge tummy and adding her hands to the fray, helping soothe the intense pressure on it.

The alabaster mare kept moaning in an odd mix of discomfort and pleasure while her belly was rubbed, the latter beginning to overpower the former after a few minutes, the telltale scent of arousal soon beginning to make itself known to the two earth ponies. The baker took initiative and started to rub lower on the nurse’s belly, going from its zenith, slowly crossing the navel with a few tickles inside that gave a few quiet giggles from its owner, sliding along the main sag with enough force to lightly indent it, and finally arriving at the main groove between it and the hips below. She slid a hand along that groove, slowly from side to side, making the other pony’s breath become ragged with lust, her mind now beginning to be clouded by a different type of bliss.

The pink pony made a few more rubs along that groove before pulling her hand back out and running it even lower on the nurse’s body, beginning to slide along her legs through her sleek, black skirt and quickly coming to its trim. She maneuvered her hands under it while keeping them touching the smooth, pale legs, and started to slide them up their insides, increasing the rate and volume of their owner’s moans.

She eventually made contact with Redheart’s panties, spiking the other mare’s pleasure for a moment before letting those surprisingly deft pink fingers slide under her skirt to the hem of her panties and work their way around to grasp it, then slowly, sensually pull them off. The normally eccentric mare kept only a huge grin as the sign of her excitement while she pulled a very wet and lacy red thong out from the other earth pony’s skirt and slithered it down her legs, inciting plenty of moans and whimpers from her along the way.

After Pinkie finally pulled the panties off of the nurse’s legs, she slowly reached them up to her muzzle and pressed them into it, then inhaled deeply from her nose, getting a massive whiff of musk that made her eyes roll up in her head a bit from the intensity. She then tossed the panties behind her and focused back on the mare it came from, putting her hands back on those slender, white legs and sliding up from the shins to the thighs, ending at the trim of the skirt and grabbing hold of it carefully. She pulled it up slightly while moving her head down near it, allowing her to peer under and see the cute, pink sex that seemed utterly frothing with arousal.

The pink pony licked her lips before diving in, shoving her muzzle into the nurse’s pussy and stuffing her tongue inside it, forcing a very loud, lewd moan from its owner. Her tongue went deeper and deeper as it wriggled around, moving in an very erratic manner, further increasing the pleasure the other earth pony found herself lost in. She put her hands back on the white pony’s legs and swiftly slid them around to her ass, passionately groping and kneading it while she plunged the depths of that soaking sex, moving her mouth up enough to place her upper teeth on the exposed clit and graze it.

All of those actions broke Redheart’s mind, quickly shoving her into the throughs of orgasm, her loud moans turned into euphoric screams with her previously soaking cunt beginning to spew her fluids out, the other mare quickly closing her lips around it, and begun to gulp down the copious amount of juices. Many mouthfuls of cum erupted from the pearl pussy in rather steady rhythm that lasted a few minutes before it finally began to slow, the other mare pulling away to leave her in her afterglow.

Laboured breathing was heard from both ponies for a couple minutes before the nurse finally managed to mutter, “Oh, wow...”

Pinkie giggled lightly at the exasperation in that as she stood up and pulled her shirt back over her breasts, then responded, “You really liked that, huh Reddy?”

“Mm-hm,” The alabaster earth pony replied with a exhausted, yet happy tone. “I’ve... I’ve never came that hard before...” She added as she looked up at the pink pony.

“Mmm... so it was my big boobies that you love so much, huh?” The baker asked sensually while she began to grope her boobs through her shirt, getting the other mare to look at her.

“Yeah,” Redheart responded, a blush growing on her face from the lewd act she was witnessing. “A-and also the milk, of course,” She added while patting her bloated belly for emphasis.

Pinkie grinned gleefully and groped herself for a few more seconds before she gasped loudly and yelled, “Wait! You still haven’t tested my foal-making abilities!”

The nurse gained a sheepish smile and responded, “Yeah, I guess I didn’t...” She attempted to sit up, but her massive belly and orgasmic exhaustion made her unable to mover much at all, so she laid back down and added, “I-I think we’ll have to do that another day, though...”

“Oh...” The pink pony looked somewhat crestfallen. “So, tomorrow maybe?” She asked, looking hopeful.

Redheart nodded and replied, “As long as nothing else comes up.”

Pinkie then broke back into her manic demeanor and whooped, “Yay! Thank you, Reddy!” She gave a quick pat on the other earth pony’s belly and said, “I’ll see you later then!” She hopped over to the door and flashed an ecstatic smile back before sprinting down the hall, leaving the nurse to smile and hug her huge tummy lovingly, blissfully ignorant of the consequences her little session will have.
