Twilight lays an egg

When Twilight's new experiment doesn't go as planned, Pinkie is quick to assist her.
All characters are futa and anthro!
Just a warning to anyone reading this- this fic is pretty fetishy when it comes to egg laying. If that's not your cup of tea, please move on!
I mostly started writing this fic for myself, but decided I wanted to share it as well! So please enjoy!

Something New

Twilight ran back to her castle, clutching the box of cookies to her chest. She weaved through the crowd of ponies in front of her as she ran, but most of the ponies in Ponyville didn't mind as they were used to this kind of thing by now. Once Twilight reached her castle, she went straight to her library. She dropped the box of cookies on the floor before frantically looking through books. The running seemed to push whatever this weight was further down Twilight, rubbing against her prostate just right. Twilight's knees buckled as she audibly moaned, looking through book after book.

Twilight's had sudden boners in public before, it's happened to everypony at least once. But this was an entirely new sensation. Something rubbing and pushing against Twilight's insides in all the right places. Twilight was worried that this might be a medical problem. Constipation, maybe?

Twilight felt the weight become heavier, bigger, even. She fell backwards in a loud huff, her cock still twitching in delight.
Twilight layed on her back on the cool, Crystal, floors of her castle. Her legs had instinctively spread, a very obvious bulge in her pants on full display. Twilight groaned, "Why? Why now? Why infront of Pinkie?!" Twilight yelled to nobody in particular. The alicorn could feel her entire body heating up as the weighted sensations never subsided. "Oh fuck it. Might as well enjoy this."

Twilight positioned herself to where she was leaning up against her bookshelf. She didn't want to risk waddling to her room as she wasn't sure if Spike was still in the castle.
Twilight's breathing became heavier as she unbuttoned her jeans, sliding them off of her figure. She tossed her garments away without another thought, looking down at the large bulge in her boxers. She palmed herself a bit, closing her eyes at the sensation, before finally lowering the boxers down. Once she pulled them off, her cock sprung up, absolutely dripping with precum.

Twilight started stroking herself in a painfully slow motion as the weight in her abdomen started pushing harder. Twilight groaned loudly at the feeling. Without a second thought, Twilight spread her legs wider, lifting her hips slightly off the ground. "Oh sweet Celestia.." Twilight cussed. She started moving her hand faster, instinctively pushing against the weight in her abdomen. The weight she was pushing against seemed to move downward. Down, down, down.. then something seemed to prod at her asshole. Twilight gasped loudly, "Wait.. am I.. is this-" Twilight interrupted herself with a throaty groan as whatever was inside of her started stretching out her asshole. Twilight began to panic, worrying that she might just be shitting on the castle floors. That wouldn't be very fun to clean up. But all of her worries seemed to melt away as her body heated up again. Twilight didn't care anymore- she was too far into this. Twilight continued to touch herself, using her thumb to rub against the head of her cock.

Twilight bit her lip as she instinctively started pushing again. Whatever was coming out of her, it was big. Twilight gasped loudly as, whatever it was, was pushing harder against her asshole. This sensation sent pleasured tingles up her spine. Twilight jerked herself faster, "Oh yes, oh yes, oh- HNNGH-"

Twilight pushed as hard as she could, grunting, as the object popped out of her body. And as it pushed itself through and out of her ass, Twilight came. The alicorn arched her back, moaning loudly, riding her high. Once she finally calmed down and had a chance to breathe, she looked down to see what had been inside of her all that time.
She was shocked to see, before her, was a large, spotted, egg.

Pinkie's Assistance

"HUH?!" Twilight practically screamed. She stumbled backward, not that far as she was already against her bookcase. Twilight gawked at the object in front of her. An.. egg? A dragon egg, for that matter? But, it couldn't be! It sure looked like a dragon egg, was the size of one and had all the right markings. But Twilight couldn't recall ever having sex with a dragon.
"Wow."

Twilight yelped as there was a second voice in the room, her head whipping to the entrance of the library.
Standing in the doorway was Pinkie Pie, frozen in her tracks. Twilight wasn't sure if she's ever even seen Pinkie that still before. In her hands was a large bowl with a covering on top of it.

The two held eye contact far longer than either of them were comfortable with. Pinkie cleared her throat, "I uh.. brought you soup because you were.. jeez, Twilight, since when could you lay eggs?"

Twilight felt her face heat up from embarrassment. She put both of her hands on her face and groaned loudly, "Pinkie.. I don't-"

"I mean, look at the size of that beauty! I'm surprised you could squeeze it out of your butthole! It sure was enjoyable to watch, though!"

Twilight moved her hands from her face to see Pinkie Pie crouched over the egg, sliding her finger across it, licking her finger.

"Pinkie! What are you doing? That thing came OUT of me!"

Pinke smacked her lips and smiled,
"I know that, silly, I saw the whole thing! But.. not up close."

Pinkie crawled over to Twilight, her nose very close to Twilight's entrance.
"Pinkie…"

Twilight's breath hitched as Pinkie nosed closer between Twilight's legs. Twilight could feel herself getting hard again. Pinkie looked up at the alicorn with bright, blue, eyes, "Is this alright, Twilight?"
Twilight nodded, her dick twitching back to life as Pinkie got closer. Pinkie gently grabbed Twilight's naked thighs, pushing her nose against Twilight's hole and inhaling, "Y' think you got anymore in you, Twi? Think you could lay some more eggs for me?"

Twilight's breathing was ragged now. She licked her lips, overwhelmed,
"W-Well.. it feels like there might be more.. my stomach is still heavy."

Pinkie mumbled something that sounded like 'good' before pressing her lips against Twilight's asshole. Twilight gasped, throwing a hand over her mouth. Pinkie's tongue left her lips as she started licking Twilight's asshole. Her hole was soaked with precum and other fluids from pushing that egg out of her, and Pinkie didn't want to miss licking up a single drop.

"Pinkie…" Twilight moaned against her hand as Pinkie Pie ate her out. Twilight shivered as she felt Pinkie's tongue press against her asshole. Pinkie pulled Twilight's legs apart further to get a better entry, before sticking her tongue inside of the princess.

"Huah-!~" Twilight moaned as she felt Pinkie's tongue explore her insides. Pinkie Pie lapped her tongue, pushing her nose against Twilight to try and taste more of her.

That's when Twilight felt it. A push from deep inside of her. Twilight flinched, "Oh- oh! Pinkie! I'm- another egg! I'm gonna lay another egg!"

Filled with determination, Pinkie pressed her face against Twilight harder, her tongue entering deeper.
"Th-this isn't funny, Pinkie! Didn't you h-hear me?"

Pinkie squeezed Twilight's thighs, her tongue making its journey inside the princess, licking everywhere it could.
Twilight felt the pushing sensation again. The object moving down, down, down..
"Ah-ahh! Pinkie! The egg!"

The egg reached its resting point inside Twilight, making her feel heavy, making her push against it.
"I-I'm laying another egg! Nghh.. Pinkie.. you.."

The sensation of Pinkie eating Twilight out mixed with pushing the egg out of herself was almost too much for Twilight. Twilight pushed against the egg as hard as she could. She wanted to grab onto something, so she grabbed onto what was closest to her- Pinkie's mane. Twilight tightly gripped onto Pinkie's mane as she yelled, pushing the egg out of her body.
Pinkie Pie felt the object pressing against her tongue. Twilight's insides clenched, pushing the egg out of her body. Pinkie licked whatever else she could and removed her tongue. She couldn't move herself that far as Twilight was gripping onto her mane, not that she minded. Pinkie watched as the object stretched Twilight's asshole.
"Hnnghh-!!" Twilight grunted, squeezing her eyes shut as she pushed the egg out of her. Pinkie watched with wide, erotic, eyes as the egg emerged. Twilight's asshole stretched around it as it was pushed further and further and-
"Huaah~!" Twilight moaned as the egg left her body.

Pinkie whistled as Twilight attempted to catch her breath, letting go of the baker's mane.
Pinkie held the egg in her hands. It was a little bigger than the last egg, fitting almost the size of a bowling ball in the palms of her hands. She wondered that, if Twilight still had more eggs, they'd be even bigger than the last.

Pinkie felt her own cock twitching at the thought. She gave the egg a quick lick and a kiss before carefully setting it aside, "Y'know, Twilight, birthing these eggs can't be easy.."

"H-Huh?" Twilight responded, dazed.

"Looks like you sure could use some help."

"W-Wait… Pinkie.." Twilight tried asking Pinkie to take it slow, but Pinkie was already behind the princess,
"Don't worry, my dear patient, Doctor Pinkie Pie will take good care of you."

Laid to Rest

"Pinkie.." Twilight breathlessly pleaded. Her mind was foggy with arousal after laying that last egg. Pinkie perched herself behind the princess, being able to feel up and down her body, as well as watch.
Pinkie hummed,

"Hmm.. tell me, Ms. Sparkle, what're your symptoms?" Pinkie nipped at Twilight's neck, ghosting her hands across the alicorn's chest, but never quite touching her cleavage.

Twilight was rock hard, mind bogglingly turned on by the current situation, especially by the way Pinkie was breathlessly speaking to her.

Twilight's legs twitched, begging for some sort of physical contact,
"I… I feel hot…"

Pinkie kissed Twilight's throat, lifting up the princess's shirt,
"And?"

Twilight sighed in delight,
"I'm.. hard."

Twilight felt her face heat up in embarrassment, not that it wasn't heated already.
"I can see that," Pinkie giggled. Pinkie managed to get Twilight's shirt off of her figure, pinching her nipples through her bra,
"But why are you hard, sweetheart? Is it the way I'm speaking to you? The way I'm touching you? Or is it…"
Pinkie snaked her hand down Twilight's body before pressing against her abdomen,
"Something else?"

Twilight wanted to answer with 'all of the above', before she felt a familiar sensation.
"Hua!~ Pinkie! Another.."

Twilight choked back a moan as she felt a new, much bigger, egg weighing against her abdomen.
"Oh? You gonna lay another one for me, love?" Pinkie purred into Twilight's ear. Pinkie pressed her palm down on Twilight's abdomen gently and Twilight grunted in response,
"P..Pinkie.."

"Hey. Twilight?"
With tear-filled eyes, Twilight glanced over at Pinkie. Instead of the erotic expression she was wearing earlier, Pinkie had a look of concern,
"Just tell me if anything is too much for you or if you want me to stop, ok?"

Twilight gulped and nodded. She might have been overwhelmed, sure, but she was positive that this is what she wanted. This is what she needed,
"Ok, Pinkie. You… you can keep going."

With Twilight's consent, Pinkie continued to touch the princess. Pinkie pressed her palm further on Twilight's abdomen, almost moving the egg herself. Twilight felt the sudden weight shift, her breath hitching at the sensation. As the egg made its way through Twilight's body, Pinkie was able to push it more and more,
"Wow, Ms. Sparkle, this one feels like it's bigger than the last two, hm?"

Pinkie kept whispering in Twilight's ear as she squirmed and moaned,
"It's gonna stretch you out nice and good. I'm going to enjoy watching you pushing against it to try and get it out of your body.."

"Huah~! Pinkie!"

Twilight moaned loudly as she suddenly felt the egg prod at her entrance. Pinkie snaked a hand down the princess, grabbing her thigh and lifting one of her legs high in the air. Pinkie licked her lips,
"I wanna see it again, Twilight. The way your asshole opens and closes around your eggs. The way it stretches you open, bobbing in and out of your gorgeous body as you push.."

Pinkie used her other hand to press down on Twilight's abdomen. Twilight shuttered, a broken moan leaving her throat.
"Push," Pinkie emphasized, pressing down again.

Twilight sputtered as the egg began to peak out of her asshole. Twilight pushed down on the egg to try and get it out. Her asshole puckered as the egg was pushed further and further and-
"HUHA~??"

Twilight choked a confused moan as Pinkie suddenly pushed the egg back inside of the princess. Twilight threw her head back as her chest heaved. Pinkie forcing the egg back up her asshole was mind blowingly pleasurable but also a tad painful.
Once Twilight caught her breath she turned to the earth pony,
"Pinkie, wh-"

Twilight was interrupted by a pair of lips suddenly on her own. Pinkie tasted exactly as she'd expect, a beautiful blend of cotton candy and chocolate. Twilight was able to get even more of a taste when Pinkie opened her mouth, licking at Twilight's teeth. Twilight sighed into the kiss, opening her mouth, making out with the pink pony.
Twilight began bucking her hips into the air, becoming hornier as Pinkie danced her tongue with her own.
Eventually, the two parted, gasping for air. Pinkie's eyes were clouded with lust, her dick throbbing under her pants,
"I can't take it anymore."

Pinkie began undressing, removing her shirt, bra, pants, then underwear.
Pinkie's cock was standing high and mighty, she wasn't as big as Twilight, but she was still impressive.
Pinkie passionately kissed the princess again, swiftly taking off her bra as well. Pinkie carefully layed Twilight down on her back, the pink pony grinding her cock against Twilight's ass.

Twilight heaved,
"W-wait, Pinkie, the egg.. it's still in me."

Pinkie ground roughly against the princess, making her groan,
"I know, Twi, I'll try and be gentle. But I really really wanna fuck that egg into ya."

Twilight's cock throbbed at that. But she was still nervous,
"What about lubrication? I'm not sure I'm-"

"Twilight. You've been laying eggs. I think you're loose enough."

"Yeah but-"

"Twilight. Do you trust me?"

Twilight looked into Pinkie's bright, blue, eyes. Behind that cloud of lust, there was genuine love in her gaze. Twilight sighed,
"Yeah. Go for it."

Without hesitation, Pinkie slipped her cock inside of the princess. Both of them moaned at the sensation.
"Growing up on a rock farm, I never coulda dreamed I'd be dicked down in a princess," Pinkie commented.
Pinkie waited a few moments to make sure Twilight was adjusted enough. When the princess began grinding her hips down on Pinkie, she got the hint that she was ready. Pinkie pulled out about half way before snapping her hips forward. Twilight made a high pitched noise that sounded very pleased, so Pinkie kept going. She dug her nails into Twilight's cutie mark as her hips kept meeting Twilight's, the two grunting and moaning with each thrust. Before long, Twilight made a surprised grunt. Pinkie slowed down, worried she might've hurt her friend, before Twilight was bucking her hips again, "Ugh.. the egg..!"

Upon stopping, Pinkie felt something poke the end of her dick. She grinned, "That lil' eggy sure wants to come out, huh?"
Twilight nodded, face scrunched in pleasure, still bucking her hips against Pinkie's cock.

"Well…" Pinkie pulled her hips back and thrusted roughly against the egg. Twilight's back arched in bliss, "HUAAH~!"
Pinkie licked her lips and leaned down, nose practically touching Twi's, "You're gonna have to work for that egg to come out."

Pinkie resumed her thrusting, a little rougher than before. Twilight was a sweating and moaning mess, tongue lolling out of her mouth as drool dripped down her chin. The egg being pushed back up into her added an entirely new sensation of pleasure she hadn't thought to be possible.
Pinkie's breathing became heavier as she squinted her eyes shut, her thrusts becoming sloppier as she felt herself slipping away, "Twi.. I'm.."

Twilight was close too, but the egg seemed to be closer. Twilight could feel the weight of the egg moving downward, even against the pushes of Pinkie's cock. Twilight could feel herself giving way, "Ah, ah, aH, AH, PINKIE~!"
Twilight leaned up and grabbed Pinkie by the shoulder, pulling her into a messy open-mouth kiss. Pinkie gladly returned the kiss, this sending the both of them over the edge. Twilight came ribbons against herself and Pinkie, while Pinkie sloppily came inside Twilight.

The two sighed and relished the moment, allowing the heat of the moment to cool down. After a moment, Twilight felt a dull ache in her abdomen. Her eyes widened, "Oh, Pinkie! Egg, egg! Let me-!"
Pinkie gasped, quickly but carefully pulling out of the princess. Upon doing so, the earth pony's cum spurted from Twilight's entrance, making a large puddle on the floor. Pinkie winced, going to grab her shirt to clean it up, but Twilight interrupted her, "Oh Celestia, oh sweet sweet CELESTIA..!"

Twilight leaned herself back on her elbows and spread her legs as far as she could, giving Pinkie an up-front and personal view of the scene. She watched as the head of a purple spotted egg began to crown at Twilight's entrance before being sucked back in. Twilight's eyes were screwed shut as she concentrated, making loud grunting noises, "Ugh.. ngh.."
Another sudden spurt of both Pinkie's cum and Twilight's own juices came from the princess's asshole, slicking it up enough for the egg to emerge. The egg crowned again as it stretched Twilight's hole even further. Twilight panted loudly, making a long groaning noise as she pushed against the egg. Twilight's asshole stretched further than Pinkie could imagine, and she was right, this one was bigger than the last.

Even more cum dripped from the sides of the egg and spurt from Twilight as she pushed. Twilight lifted her legs off the ground before moaning loudly, "Ohh~!"

Suddenly the egg sucked itself all the way back in. It was barely even half way out before doing so. The sudden event surprised Twilight, making her gasp, "N-no! I need- it needs to come out!"

Pinkie put her hand on Twilight's cheek as she panted in fear,
"Shhh.. we'll get it out, I'm here. Maybe we just need a new position?" Pinkie looked around before grabbing her shirt again, finding a clean spot on the castle grounds to lay it out, "I'm not sure how dragons lay eggs, but chickens do it sitting or standing, right?" Twilight watched as Pinkie grabbed a crystal table and pulled it near her shirt before approaching the princess. She held out a hand to Twilight and lead her to where she had set everything up. Pinkie patted the table, "Grab onto here. I'll help hold you up."

Twilight nodded before squatting over Pinkie's shirt, putting the rest of her weight onto the table. The princess sighed, "This is humiliating…"

Pinkie hushed Twilight, holding onto her hip, "I'm not judging you. I just want you to feel better," Pinkie kissed Twilight's cheek, making Twilight feel all warm inside.

Then there was the prodding. Twilight leaned over the table and groaned, "I can feel it…"

Pinkie rubbed Twilight's lower back,
"Push against it. Standing will help it slip out easier."

"But what if I-" Twilight's face flushed, suddenly stopping her sentence. Pinkie smiled, "I won't judge you. Do what you need to do. Relax."

Pinkie rubbed Twilight's back in circles, "Now push."

Twilight sighed, not wanting to make eye contact with her friend. She closed her eyes and took a deep breath before pushing. Her knees bent slightly as she grunted, her eyes squinting as she did so. The egg crowned again, slick and cum rushing out of the princess's hole, splashing onto Pinkie's shirt. Twilight became embarrassed by this, tensing up again, the egg stopping its movement.
Pinkie pecked Twilight's cheek again,
"Push."

Twilight calmed down, pushing again, more slick and cum rushing from her body. Then the egg moved. It stretched Twilight's asshole further, to the point she had to spread her legs more to make room for it. The feeling was extremely pleasurable, Twilight grunted and moaned while she pushed. As the egg reached the halfway point, Twilight squat further down, enough for her ass to almost be touching the floor. She grunted as the egg slowly emerged, "Nghh.. ugh.. hggh.."
The egg was more than halfway now, a large wave of cum squirting out of Twilight's hole, making a loud squelching sound. Twilight moaned loudly, "Oh- oh! Here it comes! It's coming out!! Ngh.. NGHHG~! I CAN FEEL IT~!"

The egg finally plopped out of Twilight's body, sitting on Pinkie's shirt. The egg leaving released all of Pinkie's cum and Twilight's slick from her asshole, making a huge mess that went past Pinkie's garment. The liquids made a very loud squelching sound, splattering over Twilight's butt, the egg, and pretty much eveywhere else. Twilight moaned loudly as her ass finally released, small spurts of cum even releasing from her own cock. Her asshole puckered at the sudden loss of the object. Twilight slumped, but Pinkie held her up. She gently lowered Twilight to the ground and layed her on her back. Once Twilight finally seemed to come to, Pinkie spoke, "Y' think that's all of 'em?"
Twilight went silent for a moment, trying to see if she could feel anymore eggs inside of her. She sighed, "I think that was the last."

Pinkie clicked her tongue, "Well that's too bad. That was really hot."

Twilight snickered, lightly punching Pinkie in the arm, making her giggle. Pinkie sat up, "You need anything? Water, a snack, wet towl?"

Twilight rubbed her abdomen and sighed, "Later. For now, I just wanna lie next to you."

Pinkie smiled, lying back down neck to princess, closer even. Pinkie traced circles on Twilight's stomach, "So why did you lay eggs anyways? Don't tell me you and Ember have been hitting it off."

Twilight giggled, "No, no, nothing like that. Ember actually needed my help. Dragons were laying less eggs than usual, so she wanted me to figure out how fertilize more eggs into dragons." Twilight looked over at the large egg soaking in her and Pinkie's fluids,
"Guess I figured it out."

"That's why you're the Princess of Friendship," Pinkie added, "Or maybe you can now be the Princess of Egg Laying!"
Twilight frowned, "Well that doesn't have a very nice ring to it."

Pinkie laughed, holding Twilight's hand in hers, kissing her on the neck. Twilight felt warm, smiling and closing her eyes. She not only figured out how to save the dragon species, but she might've gotten herself a new girlfriend as well.

Helping Hoof

Twilight chewed her pen for so long, her teeth were beginning to ache. She grumbled, tossing the pen somewhere out of sight as she approached her work. The incubator holding the dragon egg was hooked up to lots of other wires and machinery, those wires connecting to tubes, those tubes connecting to chemicals, and so on. The princess walked to the other side of her library, picking out a book and flipping through it. Twilight read everything she could on egg laying, dragon reproduction, and even the birth of ponies. But nothing she read would be able to help her current situation, and no spell she could find would even come close to the results she needed.

So Twilight resorted to potion making. Her way of potions was far more different than Zecora's. Tech, machinery, precise measuring, and so on was what Twilight learned when she attended the school of magic, after all. And besides, Twilight doubted Zecora would have any remedy to Ember's current situation.
A timer suddenly went off, Twilight's ears perking up immediately. She quickly, but carefully, put the book she was reading back in its rightful place. Trotting to her machinery, she crouched beside a beaker resting on an end table. All of the tubes connecting from various chemicals, as well as the incubator, lead to an eye dropper, dropping the precise measurements of the potion into the beaker. But something was off. The timer that went off should have indicated that the beaker was full, but the beaker barely had a quarter of the purple potion inside of it.

"That's not right," Twilight told herself. She carefully set the beaker off to the side and studied the end of the machine. She squoze the eye dropper herself, but nothing seemed to come out. Twilight then screwed it off to see if something had clogged the insides. But upon unscrewing it, the tube connecting the eyedropper started spraying dark purple liquid everywhere. Twilight sputtered as the potion sprayed all over her face, some even getting in her mouth. Luckily she had been wearing safety goggles, so her eyes were left undamaged. Twilight quickly screwed the piece back onto the machine and it seemed to be functioning normally again. Twilight groaned, moving the beaker back under the eye dropper to continue her experiment. That's when Twilight got a good look at herself- her white lab coat was now coated a dark purple, as were her hands, and most likely half of her face.

"Well that's just great," Twilight complained, removing her once-white lab coat from her body and slinging it over her shoulder, "Guess it's bath time." Twilight left the library to clean herself. “I might as well get cleaned up,” Twilight told herself, “I'm supposed to be visiting Pinkie Pie in a few hours to pick up my order of cookies."

Cookie Order

After taking a few hours to clean herself up and get into comfortable clothing, Twilight made her way to Sugar Cube Corner. Twilight went for days eating nothing but instant noodles because of her experiments, so Spike had suggested Twilight treat herself to something sweet as a break. Plus, a small trip to Sugar Cube Corner was always a good excuse to see Pinkie Pie.
Twilight entered the bakery, the bell connecting to the door ringing as she arrived. Twilight was hit with the sweet smell of cupcakes and cookies upon entering. She couldn't help but lift her nose into the air and inhale the delicious scent.
"Hiya Twi!"

A bubbly voice snapped Twilight out of her thoughts, making her jump, "Oh-! Hi Pinkie Pie!"
Pinkie stood at the other side of the counter, shaking her hips a bit out of excitement of seeing her friend. Twilight couldn't help but feel her face flush at the sight.

"So! I'm assuming you're here to pick up your cookie order? Or is it just to see little ol' me?" Pinkie poked both of her cheeks, making large, puppy, eyes when saying this.

Twilight giggled, "It's always great to see you, Pinkie! But I am here for my cookie order. I've been busy in the library with some experiments."

Pinkie gasped, "Experiments?! Like, magic experiments?! Ooo how fun! Is that where you've been all week?" While saying this, Pinke grabbed a light blue box from under the counter, plopping it in front of Twilight.
Twilight sheepishly rubbed the back of her neck, "Eheh.. yeah.. it's been a frustrating subject to tackle. See, Ember came by the other day-"

Twilight was cut off by a sudden sensation. There was a sudden weight in the alicorn's lower abdomen. As if she had swallowed an entire watermelon whole and it just hit the bottom. Twilight fell forward, catching herself on the edge of the counter, holding her stomach. This alerted Pinkie,
"Twilight? Are you alright? What's wrong?"

Twilight heaved a heavy breath, sweat beading on her forehead,
"I'm.. I'm not sure. Suddenly I feel like-"

Twilight was interrupted again by the weight in her abdomen. But this time, the weight shifted and pressed against a certain spot inside of her. Twilight choked back a moan as, whatever this weight was, became heavier. And the heavier it got, the more it pushed against her sweet spot. Twilight could feel her dick suddenly twitching inside her pants. Pre-cum already beading at the tip. Twilight gasped suddenly, "S-sorry Pinkie! I'm-I'm suddenly not feeling too well. Well uh- thanks for the cookies! I'll see you.. sometime!"

Twilight hurriedly grabbed the box of cookies and booked it for the door.

"Wait! Twilight!" Pinkie attempted to call out, but it was no use. Twilight was long gone..
