Pinkie Pie's Pregnancy Problem

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...”
