Sharing is Caring!

“Pinkie? Why does it look like you’re pregnant?” Fluttershy asked in disbelief as her pink friend bounced around her. She dropped the bag of bird seed in shock, then grabbed her by the shoulders. “What happened to you?” she asked, doing her best to keep her in place.

“I went into Twilight’s super secret naughty library and found these!” Pinkie stopped bouncing, reached into her mane, and pulled out her new favorite pair of panties. She sat down and held them up, stretched out between her two front hooves. “See? Aren’t they super duper awesome?”

“Um... these panties made you pregnant?” Fluttershy cocked her head to the side.

“Yeppers! I touched a book Twilight told me not to touch unless I wanted a good rutting, saw a bright light, and then these appeared on my booty!” She shoved them into Fluttershy’s face. “I couldn’t take them off at first, but when they appeared, I didn’t want to, and when they made me squirt like a bajillion times, when I took them off, they were all clean!”

“Y-Yes, I can see that, but... who are they?” Fluttershy asked, hesitantly grabbing the panties from Pinkie’s hooves.

“Tentacles!” Pinkie chirped with a wide grin on her face.

“Tentacles?”

“Tentacles! And they laid their eggs inside my womb and pumped me full of cum! It was easily the best rutting I’ve ever had in my life!”

“So... what, you just put them on and tentacles appear inside them?” Fluttershy asked, her tail hiking up just a little at the thought.

“I think so! I’d put them on myself first, but well... I’m already preggers! And they make you feel soooo good! Who wouldn’t want a belly full of tentacle eggs?” Pinkie gasped, her eyes going wide. “What if I give birth to them and they hatch and then they rut me giving me more eggs to give birth to and then I can give eggs to each of my friends and maybe Princess Celestia, Cadence, and Luna?!” She took a deep breath. “And then they can make us all feel all awesome and tingly inside!”

Fluttershy felt herself blush as a small trickle of arousal slipped down her inner right thigh. She sat down in a hurry, hoping to hide the fact that she was getting turned on. “Is it really that good?”

“You have noooo idea! So you wanna try them on? And can I watch??” Pinkie asked, pressing her head up against Fluttershy’s forehead. “And maybe I can give birth to my babies when you’re getting rutted!”

Fluttershy furtively gazed around, clenching the panties tightly in her hoof. “I think we should go inside,” she squeaked out, unable to look her friend in the eyes as her cheeks turned a rosy pink.

“So that’s a yes? That’s the spirit!” Pinkie exclaimed, dragging her towards the cottage. Once they were inside, she kicked the door shut and dragged Fluttershy up to her bedroom. “You want me to put the panties on for you?”

“S-Sure,” Fluttershy murmured. She lifted her right hind leg and let Pinkie thread the panties up, then lifted her other leg to step into the other hole. Her friend tugged the panties up with her teeth, then tugged them right up against her sopping wet slit with her hooves.

Pinkie couldn’t help but stare at the panties’ crotch, for Fluttershy’s labia were perfectly encased in the soft fabric. “Already feeling frisky? I know I would!” Pinkie sat down on the floor, feeling no small amount of wetness beneath her. She stood up, peered between her legs, and noticed a thick wet stain on Fluttershy’s carpet. “Oh hey, I’m just as wet as you are!”

“Pinkie, could we, um... tone things down a little bit?” Fluttershy asked sheepishly.

“Hey now, you’re the one who agreed to put on a pair of panties that contain a portal to tentacles that’ll lay eggs inside of you,” Pinkie said with a smirk as she flopped down on Fluttershy's bed, tugging her up beside her. “Besides, we fuck like every other day anyways; you know how I can get!” she said with a giggle and a snort.

Fluttershy rolled her eyes, unable to keep a grin from sliding on her face. She hiked her tail up and looked down at her crotch, her eyes furrowing in confusion. “Hey, Pinkie? Weren’t the panties purple when you pulled them up?”

“Yeah, why?”

“Well, they’re not purple anymore and your cutie mark appeared on the front.”

“Huh?” Pinkie lifted her head from the pillows and looked between Fluttershy’s hind legs. Instead of seeing a dark purple pair of bikini panties, she saw that they were light green with a silky white lace trim around the leg holes. “That’s weird... Maybe they change to your favorite color? Purple is my favorite color, but that changes almost every day because I like all the colors!”

“Well, green is my favorite color, so I guess that makes sense. But why your cutie mark?”

“Well, when I played with the tentacles, Twilight’s cutie mark was on the front! Maybe it shows the pony who played with them last?” She gasped. “Do you think that Twilight laid eggs already? Why didn’t she tell me? I’d love a tentacle creature of my own!”

“From the look of things, you just very well might! So...” Fluttershy wiggled her butt, trying to coax the tentacles out. “When do they, um... come out?” she asked.

“I dunno! When I touched Twilight’s book, I got super duper dizzy, so I flopped down on some pillows so I could feel better, and when I got up, they suddenly slithered inside! So... maybe a few minutes?” she asked, cocking her head to the side as she shrugged.

“Do I have to do anything special?” Fluttershy rolled over onto her back, giving Pinkie an uninhibited view of her crotch.

“Nah, just stay wet! I don’t think they’d come out if you weren’t aroused. I know I wouldn’t!”

Fluttershy’s eyes went wide as her labia tingled, feeling little bolts of electricity dance across her lips. Suddenly, something wondrously warm and wet slithered its way into her panties, pressing firmly against her pussy, running up and down between her labia. Pushing past her thick, swollen lips, the tentacle teased her entrance, making her nethers tingle as it wiggled against her moments before it slipped inside of her. It squirmed around her tight, velvety passage, going agonizingly slow as it excreted a warm liquid. It grazed against her G-spot, eliciting soft moans from her as it began to massage her favorite spot. “They’re here...” she whispered, her eyelids fluttering.

“Awesome!” Pinkie spread her hind legs wide and rubbed her clitoris with a hoof, little soft moans slipping past her lips as it grew wet with her arousal. “Hey, I think I felt one of my babies move inside me!” she said with a gasp.

“Were the eggs big or small?” Fluttershy asked curiously. She panted softly as another tentacle appeared, running between her butt cheeks as she felt it spray a warm, sweet-smelling liquid against her sphincter. It squirmed against her hole, pushing its slim tip inside of her a few inches, then started sliding back and forth as it pumped more of its lube inside of her ass.

“About as big as my hoovsies!” Pinkie said with a giggle. “They felt awesome going in, and I bet they’re going to feel even better coming out! It’s probably gonna feel like those big anal beads you like to use on me!” Before she could say anything else, a river of white cum slipped from her folds. “Hehe, I think they’re coming!”

“Y-Yeah?” Fluttershy took a few deep breaths as another tentacle emerged and pressed against her lower lips, easily three times as thick as the other two. The one in her ass slithered most of the way out, stretching her hole as it swelled up to four times its size. She felt some of the liquid in her butt trickle out, only to be replaced with fresh loads. The thin tentacle in her pussy slithered away, returning into the portal, leaving her feeling rather empty.

The thick tentacle squirmed against her tight entrance but did not push further, almost as if it was waiting for something. Fluttershy felt a small tingle grow in her core, and with each passing second it grew stronger and stronger until it felt like she was in the worst of her estrus cycle. Unable to wait any longer, she swished her tail from side to side and bucked her hips upwards, hoping that the tentacle would slither its way inside of her and fuck her until she was nothing more than a quivering puddle of cum. “Come on! You can’t just keep teasing me!” she said, nearly whimpering as her arousal mixed with the tentacle’s aphrodisiac soaked through her panties. She felt it pool around her butt, soaking into the sheets she’d just finished washing that morning.

She groaned like a true mare as it finally pushed against her entrance, slowly stretching her labia apart. When it felt like she could take no more, her lips accepted her new lover, letting it slide a few inches inside of her. Her lips formed a tight ‘O’ as she clenched down on it, feeling her passage ripple along its length as it twisted back and forth inside her. The tentacle wormed its way further into her pussy, stopping only when it brushed against the entrance to her womb. It lay still, letting her get used to its enormous size as is gently secreted more of its liquid inside of her.

“P-Pinkie?” she gasped out, barely able to form a coherent sentence. She rolled over onto her side, laying her head between her forelegs as she gazed at Pinkie’s dripping and puffy slit. “Oh my gosh!” she said, her eyes going wide as the front of an egg easily as thick as her hoof started to emerge from Pinkie’s pussy. It was light purple, almost mimicking the shade of the panties she wore.

“C-Can you see it?” Pinkie grunted as she bore down, pushing the egg out with all of her strength.

“Yeah...” Fluttershy blushed furiously as the egg spread Pinkie’s labia apart, momentarily pausing as it reached its widest part.

Pinkie clenched her eyes shut and grit her teeth as her pussy was stretched to its absolute limit. “Nnng... come on, you!” she yelled, sweat forming on her brow. She took a couple of deep breaths, relaxing momentarily. The egg slipped back inside of her a little bit, but still rested at her entrance. “Now... for the final push!” She bore down once more, grimacing as another egg slipped into her pussy, pressing up against the first one. The first egg finally slipped out of her with a wet plop, laying on top of her cum-soaked tail. She wanted nothing more than to relax, but a quick glance at her bulging tummy made her think otherwise.

“How many do you think there are?” Fluttershy asked in awe, her eyes still locked on Pinkie’s gaping pussy. She saw the tip of another egg a few inches inside of her, Pinkie’s pussy rippling across it as she pushed it out.

“I dunno!” Pinkie grunted out. She rolled over onto her side and curled up into the fetal position, the pressure that the eggs exerted on her sore tummy diminishing slightly. “That’s a little better...” she muttered as she wrapped her two front hoovsies around a pillow. She clenched it tightly against her breast as she closed her eyes, her core positively aflame with lust. A whimper of need slipped past her lips as another egg slipped from her folds, falling down next to the first one. “Oh gosh, I gotta start thinking of names for my new babies!” she said, her eyebrows furrowing in thought, though that idea was quickly shoved aside as a thicker egg pressed up against the inside of her entrance. She bit down on her bottom lip, pushing as hard as she could, and when she felt like she was about to run out of energy, it popped free of her folds. “Oh... my... gosh...” she moaned, her vision going blurry.

“I don’t know if I can handle giving birth to so many eggs...” Fluttershy whispered, the scent of tentacle cum that oozed from Pinkie’s slit driving her wild. She wiggled her hips and clenched down on the thick tentacle a couple of times. “You can start, Mr. Tentacle. I think I’m ready,” she said, a sly grin sliding on her face. The tip of the thick tentacle moved up and down as if it was nodding, then slid almost all the way out. Before she could utter another word, it wiggled its way back inside of her stretched-out pussy until it bottomed out again. It pulled back, then slowly built up a slow, rhythmic fucking, its tip pushing against her G-spot with each and every thrust.

“Oh...” Pinkie groaned as more cum slipped from her folds, the bulge in her belly diminishing greatly. She massaged her belly with a hoof, exerting a little pressure on it to help the process along. More tentacle cum poured out of her folds, followed by several smaller eggs half the size of the first two ones. Her eyes clenched shut as each egg grazed against her G-spot, and as she neared her peak, she lowered a hoof to her clitoris and humped it, furiously rubbing her favorite spot all the while. With a cute squeak, she squirted, her hoof catching most of her cum as she rubbed herself all through her orgasm, and as it faded away, she flopped down, her chest heaving. “I... I think that’s it...” she murmured, feeling the last little bit of tentacle cum drip from her folds.

Then something brushed against her cheek.

Her eyes shot open as she lifted her head from the pillow, noticing a tentacle hovering just in front of her lips. She looked at her butt and saw the other end still inside of her. A smaller tendril slipped from her folds and wove its way up, wrapping itself around her clitoris. Her mouth popped open as she moaned, giving the other end of the tentacle its opportunity. It forcefully pushed itself inside her mouth, forming a tight seal around her lips as it squirted its aphrodisiac all the while. With her cheeks bulging, Pinkie had no other option than to swallow it all, for the seal around her lips simply wouldn’t let her spit it out. She took a couple of big gulps, the overly-sweet liquid painting the inside of her throat white, and on the second gulp, the tentacle slithered into her throat. Her eyes drifted shut, her hind legs twitching as the small tentacle on her clitoris wiggled to and fro. The one in her throat steadily pumped away, eliciting no small amount of arousal from her gaping slit.

Fluttershy winced slightly as the tentacle in her pussy stretched wide, as if it was pushing something inside of her. “Th-The eggs...” she whispered to herself, a sly grin forming on her face as she watched Pinkie get throat-fucked, silently hoping that she’d get the same treatment later on. Suddenly, something warm and wet latched onto her clitoris, sucking at it with wild abandon. Her hind legs clamped shut on instinct but the sensation only grew in intensity. Her eyes rolled into the back of her head as her wings trembled from the sheer pleasure, and the heat in her core grew to a raging inferno that she had no intention of putting out anytime soon. Alas, as she fought to keep herself from cumming, the tentacle blew its load deep inside of her. She felt its tip blossom wide inside of her. Her belly slowly expanded as egg after egg, combined with a warm and heavy load of cum, was pushed inside her deepest recesses. Yes! Yes! she thought, bucking her hips. “Make me a mommy!” she groaned, feeling little lightning bolts of pleasure soar throughout her body, making even the tips of her hooves tingle.

Pinkie whimpered around the tentacle lodged deep in her throat, feeling herself teeter on the edge once more. A simple squeeze and a slither across her clitoris was all it took, sending her into yet another blissful orgasm. She squirted harder than before, her juices splattering across Fluttershy’s panties, hind legs, and tail until she had no more. The tentacle around her clitoris gently slithered away, leaving her cute little love button alone. It throbbed, covered in the juices the tentacle left behind. Suddenly, she felt several big bulges travel through the other end of the tentacle still lodged deep in her pussy. Her eyes went wide as her breathing quickened, watching as each thick bulge traveled up its length, only to press firmly against her lips. She spread them as wide as she possibly could and was richly rewarded. Her stomach warmed with its cum, making her feel slightly bloated, as if she’d just chugged a gallon of water. It slipped out of her mouth and nuzzled her cheek, leaving behind a thin trail of cum that it spread down her neck, back, and finally onto her butt as it slowly retreated back inside of her. After a couple seconds, it disappeared entirely, leaving her feeling dreadfully empty.

“Pinkie?” Fluttershy asked in a hoarse voice, her eyes locked on the eggs that Pinkie had just pushed out of her.

“Y-Yeah?” She rolled over, her eyes going wide once more as she noticed that Fluttershy’s belly was easily twice as large as hers had just been minutes ago. The eggs near her hind legs starting vibrating, then cracked open, revealing several dark green tentacles. Before she could utter another word, they all spit out a light pink mist up into the air that settled down upon the two of them.

Fluttershy’s mind turned fuzzy as the mist soaked into her fur. The heat in her core returned with a vengeance, and she felt the thick tentacle slip back into the portal, leaving her feeling needier than ever. Even though she’d just had a mind-blowing orgasm, she still felt really pent-up. “I... I think we need to share them with the rest of our friends...” she said, looking into Pinkie’s eyes with a sly grin.

“Definitely! But let’s hang here for a while longer; I think I’m good for another few rounds!”
