Hyper Gravid Gabby Griffon

 

“Princess! Princess Twilight! I've got it!” Gabby called out as soon as she stepped into the gigantic castle. Her footsteps were as loud as her voice as Gabby stomped through the halls. “Where are you? I brought the thing you wanted!”

 

A purple aura surrounded Gabby and pulled her into a nearby room. “Shhh! Nopony needs to hear you making such a racket!” Princess Twilight Sparkle groaned. “I told you, this is a secret operation and you can't scream things like that.”

 

“Oops, sorry!” Gabby blushed as she handed over the sheet. “I got it just like you asked. Nopony saw me at all.” The griffon gal smirked and puffed out her chest. “Only a few griffons near the display caught me but they just shrugged.”

 

“What? I said you shouldn't be seen by anypony!” Twilight groaned.

 

“I did. Only griffons saw me.”

 

Another groan from Twilight echoed through the room. “Well, since the whole army of Griffonstone isn't beating down my door, I guess it's fine. Did you bribe them or something?”

 

“Pretty much.” Gabby giggled as she pulled out her coin purse and shook it. “Took every coin I had just to get away but I'm sure it'll be fine.”

 

“Whatever. As long as we don't get caught, there wont be any trouble.” Twilight carefully unfolded the sheet and smiled as her prize was finally in reach. “Wow....it's incredible.”

 

Twilight's magic reached out and grabbed the massive bone lying on the table. She pulled it close and gasped at the sheer size of it. “Wow...is this the femur?”

 

“Nah, the humorous. That's the arm bone, right?” Gabby shrugged as she sat down.

 

“It comes up to my waist! No way this is the humorous!” Twilight shuddered as she inspected the petrified bone. “It really is....Just how TALL was Gnasher the Griffon?”

 

Another shrug from Gabby. “No one can really say. Legends say he was at least fifteen feet tall. Some sort of odd genetic mutation led to his massive size. Brawny fella for sure. He was destined to lead the armies of Griffonstone till his death.”

 

Twilight cackled as she continued to stare at the bone. “This will be a huge help in my studies on mutations. Thank you, Gabby.” Twilight levitated a huge bag of bits over to the reclining griffon.

 

“So, what are you even gonna do with it? I wanna see! Do you need any help?” Gabby seemed to overlook the gigantic bag of money as she leaned over the table. “Now you've got my curious about all this scheming and magic stuff.”

 

“Hmm. It might help to have a griffon DNA sample nearby to compare. Let's go!” Twilight pulled Gabby along as the perky princess skipped her way to her laboratory. “Sit still and if I need you, I'll let you know.”

 

“Can do!” Gabby smiled as she took a seat. It took all of three seconds before Gabby had jumped up from her chair and began to wander around the lab. So many burners, chemicals and funny equations on the wall just waiting for someone to mess with. Gabby was like a child in a candy store, touching, prodding and shaking up everything her claws could find.

 

Twilight focused her magic into her horn and closed her eyes. She reached out to the latent magic in the air and swirled it around her horn, amplifying her incredible powers. Twilight opened her eyes, revealing the powerful glow of magic brimming through her.

 

“Hey Twilight, what's this?” Gabby called out. Twilight averted her gaze for a moment, breaking her concentration as she noticed the nosy griffon holding up a few beakers and vials.

 

“No, Gabby! Don't!” Twilight screamed as her magic erupted from her horn. Chaotic beams surged through the room, zapping everything it could. Gabby flew back as a beam slammed her right into the chest, shoving her right into a wall.

 

Twilight cried out as she struggled to stop the wild magic. A final flare of power surged from her horn before the spell finally ended. “Wh...why?” Twilight moaned as she slumped to her knees. Her body felt like lead as the heavy toll of her magic began to make itself known. Twilight eased herself down to the floor before passing out.

 

While Twilight slept, her magic began to work. Gabby's body took the full brunt of the spell, changing her body little by little. Her bones creaked and groaned as they elongated inch by inch. Gabby's body softened as the magic forced chubby deposits of fat on her body. Her breasts, hips and rear plumped up, giving her the shape of a fertility goddess. The biggest change was her tummy as it slowly inflated like a balloon.

 

Gabby's stomach showed no sign of growing as it began to dominate her body. What was once a small, softball like bulge had quickly grown into the size of a watermelon. Gabby scratched her stomach in her sleep as she continued to swell out, giving her the appearance of a griffon that had swallowed an entire beach ball.

 

The oversized griffon groaned as her body continued to grow. Her growth spurt seemed to continue on for minutes on end, with short, massive periods of her body exploding upwards and outwards as her body slowly enlarged. Her clothing stood no chance against such an unrelenting growth, bursting off her body as her new height, weight and impossible stomach reduced her outfit to shreds.

 

 

 

 

 

 

 

“Uhhhhnnnngggg....Twilight?” Gabby groaned. She rubbed her head for a moment and sighed. “What...happened?” Gabby opened her eyes to see three things blocking her view. A set of full, ripe tits and a massive belly. “Oh.....this isn't good.” She muttered.

 

Gabby rolled over to her side and eased herself onto her feet. “What....did the room shrink? Gabby scratched her chin as she looked over the laboratory. “I'm SURE the door frame was wider than I was....and that I was wearing CLOTHING when I walked in.” Gabby blushed as she struggled to hide her nude body, but there was just so much of her to hide.

 

“Twilight? Twiiilight?” Gabby called out. The gigantic griffon tip toed around the various tables to find Twilight in a deep sleep. “Hey....Twilight....wake up!” Gabby moaned as she felt a stirring inside her belly. A loud, boisterous growl echoed from Gabby's stomach, forcing Twilight awake.

 

“Mmm...Spike, just go get some gems from Rarity...” Twilight mumbled. She slowly rolled over and opened her eyes to see a large, quivering belly looming over her. “AHHH! WHAT THE?” Twilight screamed as she scooted away from the massive orb hovering in the air.

 

“Twilight, thank goodness you're awake!” Gabby blushed as she tried to rub her stomach. “I'm HUNGRY! Can you get me a snack?” Another gurgle snapped Twilight out of her daze, forcing the alicorn to her feet.

 

“Wha...I mean....what happened? Nothing should have caused such a crazy reaction like this...Gabby, why did you distract me!” Twilight puffed out her cheeks. More upset growling caused Twilight to sigh in defeat. “I guess the first thing would be to feed you...and see if I have anything to cover you up...”

 

Gabby was content as could be as she dove into the pantry. The burning hunger in her stomach was quelled with anything she could get her hands on. Chips, cookies and all manner of snacks were shoveled into her mouth at quick as Gabby could manage. “Mmm, thanks Twilight!”

 

“No problem...I'll be back with something to cover you up.” Twilight blushed as Gabby innocently wiggled her bare behind. The princess rushed to her bedroom and looked upon her wardrobe. “Hmm...no...nope...definitely not.” Twilight groaned as she looked through everything. “I guess...would this be sufficient?”

 

By the time Twilight had returned, Gabby was already done with the pantry. Her impressive stomach seemed to have no limits as it drooped past her knees. “Oh man, that really hit the spot. Mind if I check the fridge?” Gabby giggled as she waddled over to the refrigerator.

 

“N..no problem!” Twilight clenched her teeth as she looked at the destruction of her pantry. “There was enough food in there to feed ten ponies for a week...”

 

“Here...I brought you something to cover up.” Twilight blushed as she held out a massive bedsheet.”

 

“Thanks. It's getting kind of chilly in here.” Gabby smiled as she pulled her belly and breasts from the fridge. She wrapped it around her massive body like a giant toga robe and continued her eating. “Mmm, this cake is really good!” Gabby moaned as she chomped it down in three bites.”

 

“That....I bought that for me!” Twilight whimpered as Gabby continued to demolish every crumb in front of her. “I gotta find out what happened!” Twilight rushed back to the lab, leaving Gabby to devour everything in her path.

 

“Okay...what happened?” Twilight sighed as she looked over her laboratory. “I stood here...Gabby was there...after I told her NOT to do anything.” Twilight huffed as she took her original position. She looked over her table and gasped as she found her her biggest clue.

 

“The bone is gone? My spell was to restore the bone to its natural state so I could extract marrow from it.” Twilight sat down and reviewed her notes. “The only reason this backfired...was Gabby. She got hit square in the chest with the magic. Did something happen?”

 

A deafening belch echoed through the castle, snapping Twilight from her thoughts. “Gabby! I need to examine her if she got hit with the spell.” Another belch made Twilight hurry her pace. “As long as she didn't find my hidden ice cream in the back...”

 

Twilight watched as Gabby scooped out the last bite of double mint chocolate chip from the gallon container of ice cream. “Oh man, that was just what I needed! Thanks, Twilight.” Gabby moaned as she struggled to rub her distended stomach. Gabby's belly dominated her features as the wide belly hung low and heavy.

 

“So...how do you feel now?” Twilight asked as she used her magic to gently probe Gabby's body.

 

“Better for sure! I felt like I hadn't eaten in my entire life. I wonder why?” Gabby asked as if her problems weren't completely obvious.

 

“Hmm...Nothing unusual on the outside. I'll have to probe deeper.” Twilight hummed along with her magic as her purple aura seeped into Gabby's skin.

 

“What? I'm sensing multiple magic sources inside you...that can't be right!” Twilight growled as she probed further. She focused her magic and pinpointed the source of the anomaly. “They seem to be coming from your belly. What in the world would cause that?”

 

Gabby giggled as she sat down and rubbed her stomach. “I think I know why. Put your hand right here.” Gabby demanded as she grabbed Twilight's wrist and forced it onto the massive swell of her stomach.

 

“Why here? What could I possibly find out that my magic can't find?” Twilight let her hand roam Gabby's tummy for a moment until she felt it. A small, outward bulge that seemed to react to Twilight's touch.

 

Twilight stared at Gabby as the simple minded griffon smiled back. “That spell of yours? You got me pregnant! Ready to be a father?”

 

“Uh...I....guh...” Twilight sat down on the floor with her hand still on Gabby's stomach. “But...how? The only compatible DNA in the room was from the fossilized bone...”

 

Gabby shrugged as she relaxed in her chair. “Huh...think that's why I'm taller, too? Maybe the spell did more than just knock me up.”

 

Twilight gasped, smiling wider and wider as she jumped to her feet. “So wait...I DID manipulate his DNA? WOO!” She hopped in joy for a moment or two before turning back to Gabby. “Forget the bits I gave you in the study. I'll quadruple your pay if you stay and let me study your new body.”

 

“Sure...but can it wait till after a nap. All this food is making me sleepy.” Gabby stretched out, making the chair groan under he massive weight.

 

“Of course. We don't need to start right away. Just let me know if you feel funny or if you need anything.” Twilight helped Gabby to her feet and aided the gravid griffon to a guest room. Even the bed frame creaked as the giantess griffon as she slammed herself into it.

 

“Ahh, this is better.” Gabby cooed as she pulled the sheets over her body. The sheer size of her belly made it impossible for the blankets to cover her legs at all. “G'night, Twilight.” Gabby barely whispered before passing out.

 

As soon as Gabby fell asleep, the magic still in her body kicked in. Twilight watched as the giant griffon continued to grow, her legs and torso elongating as the magic of Gnasher the Griffon forced Gabby bigger. “Oh my goodness...” Twilight gasped as there seemed to be no limit to how big Gabby would get.

 

“She was around five feet before the spell....at least fifteen afterwards. She must be twenty feet tall at this point and Gabby is still getting bigger!” Twilight recorded the strange magic for as long as she could until it stopped. “How fascinating.”

 

Gabby slept well into the next morning. Her body continued to grow in little spurts, making the bed grunt and groan as it struggled to contain the giantess. A titanic growl echoed through the castle, alerting all that Gabby was awake.

 

The gravid griffon bent herself down and pushed through the castle. Her belly bounced freely as her new size made it impossible for any sheet to cover her improved assets. “Hungry!” Gabby screamed as she squeezed her way into the kitchen.

 

“G-Gabby! Good morning!” Twilight blushed as Gabby's breasts were inches away from the top of her head. “You..um...hungry?”

 

“Oh gosh, YES! I NEED something to eat so badly!” She pushed past Twilight and opened the pantry to find the shelves bare.

 

“Gabby, you ate ALL my food yesterday. The only place that could even cater to your needs right now would be Sugarcube Corner.”

 

“Then that's where I go!” Gabby boasted as she forced her way past Twilight. A needy hunger burned deep within Gabby that needed to be satisfied and nothing would stop her.

 

“Gabby, wait! You aren't decent!” Twilight tried to stop her but even with her magic, Gabby couldn't be stopped. “Oh goodness...” All Twilight could do was follow Gabby as she slipped through the front doors.

 

Everypony was staring as Gabby stomped her way through Ponyville. Most were in shock. Others in awe. Some with the reddest blush you've ever seen. Gabby didn't seen to care as she made her way over to the best bakery in town.

 

“I need one of EVERYTHING!” Gabby screamed as she broke through the door frame. The ponies inside were stunned as Gabby used her belly to push and shove her way up to the counter. “I'm serious! You never see a pregnant griffon before?”

 

“Oh goodness me! You poor dearie.” Cup Cake reached out and grabbed Gabby's hands. “I understand completely. If you wait behind the store, we'll gladly ease those cravings of yours.”

 

“You will? Oh thank goodness! Mind if I take this for now?” Gabby groaned as she reached out and gobbled down a massive cake in seconds. Frosting was smeared all over her face as she devoured the cake, moaning in delight as that hungry itch was sated for a moment.

 

“Mister and Missus Cake! I'm so so SO sorry about this...” Twilight whimpered as she watched Gabby completely finish off the door frame. “I reminded her of this place without even thinking and..ugh...” Twilight pulled out a slip of paper and slammed it on the counter. “Whatever she orders...and whatever she damages...fill out this form and I'll reimburse you the costs.”

 

The Cakes sighed in relief as the gathered up what they had ready for Gabby. One by one, each delicious treat was crammed into the pregnant bird's mouth. “Oh yesh...this is what I needed!” Gabby moaned as her stomach resumed its growth.

 

“You know...it might be a bad idea if you keep eating like this.” Twilight mused as another whole cake was pushed into Gabby's sticky, stained mouth. “I think a feedback loop is draining all your strength to fuel your growth, which starves you of nutrients and forces you to eat like this.”

 

“So? I can't help it, Twilight!” Gabby whined as she struggled to caress her stomach. Her womb dominated her torso with her heaving chest sagging on either side of her belly. “I need to keep myself fed as well as provide for these little guys. Plus...it just...feels....so good!” Gabby moaned as her stomach rippled and swelled.

 

“Nnnggggffffff.” Gabby grunted as her swollen belly continued to grow. She reached for the tip of her stomach and struggled to rub it. A little pop filled the air as her navel forced itself as an outie. “Ahhhhh! That feels so much better!” Gabby couldn't help but sigh. Her stomach growled louder than before, forcing her to resume the fattening feast before her.

 

“I'm worried there wont be an upper limit to all this. If you keep growing, there might not be a way to separate your DNA from Gnasher and you'll be stuck at a size too big to contain.”

 

“Do you even want to do that while I'm pregnant though? I'm not saying that you're unskilled at magic, but what if something goes wrong again?” Gabby asked between swallowing cupcakes whole.

 

Twilight bit her lip. “You're right. I have to find an acceptable way to rid your body of his DNA without endangering you. I hope you don't mind waiting a few days as I...I...I...oh gosh...”

 

The alicorn blushed as Gabby heaved one of her own gigantic tits to her face and suckled herself. A thick, creamy trail of milk dribbled from the sides of her mouth, only serving to fill her belly even bigger. “I don't mind, as long as you keep the food coming. I could be a national hero for this! I bet the military would LOVE a whole army of Gnashers to strengthen the army!”

 

“Hehe...yea...great.” Twilight whimpered as everything seemed to be crashing down around her. “Let's just take this one step at a time, Gabby. We need to find a place to keep you while you grow so you don't disturb the town...and to keep you clean.” Twilight winced as Gabby smeared another cake all over her lips.

 

 

 

 

 

 

 

With the help of Twilight and her friends, Gabby waddled her way to the edge of the Everfree forest. Seclusion from Ponyville was guaranteed at such a dangerous location, away from the prying eyes of those eager to gaze at the titanic griffon.

 

“I know it's not life at the castle but at least I wont have to cover you up.” Twilight sighed as Gabby stepped into the nearby pond.

 

“Hey, this is pretty great, though. The water is so nice against my itchy skin and aching joints.” Gabby cooed as she sat down in the pond. “I think I'll be fine...as long as I get some food out here.”

 

Twilight gasped as another angry gurgle escaped from Gabby. “You're still hungry? I told you that the magical feedback loop was bad! Now you'll need more food, which will make you taller, which will make you want to eat again!”

 

“Well, it's not just me anymore.” Gabby blushed as she reached out and pat her stomach. “How many little guys am I even carrying?” The gravid griffon pouted as she let her arms fall to her sides. “I can't reach around my belly anymore...”

 

Curious herself, Twilight reached out with her magic. Her eyes widened as dozens of little lights began to glow within Gabby's womb. “Um...I...Let's see...” Twilight did her best to count the dozens of shifting lights squirming about inside Gabby,

 

“I count....fifty four...” Twilight bit her lip as she looked upon her friend. “Fifty four babies...all at once....”

 

“Wowie! That's huge! No wonder I feel so heavy.” Gabby giggled as her stomach growled again. “I hate to be a moody mommy, but could you hurry back with some food?”

 

“Yea...yea sure.” Twilight closed her eyes and teleported to the Ponyville market. “How in the world am I ever going to feed her? At the rate she is growing, can even Equestria feed her?” Twilight took a deep breath. “One day at a time. Keep her fed while you research this. You can do it.”

 

Twilight started the next few days in a blinding rush. Before the intense growl of Gabby's stomach shook the town was awake, she would teleport over to Gabby's temporary home and quickly took some measurements.

 

Then it was the not so easy task of quelling that endless hunger. Wagon after wagon of food was offered to the giant griffon, sating a never ending hunger. As soon as she took the first bite, the magic still in her body would ignite new growth. Her body never seemed to stop once the food began, leaving her beached upon her belly until her legs and arms could catch up to her frenzied eating.

 

Twilight did her best to do any sort of research that she could. Without her lab equipment nearby, it was taxing just to record basic measurements before Gabby would shatter her own records. Progress was made at a snail's pace as Twilight struggled to handle the responsibility of keeping Gabby sated enough to run any sort of tests on the growing griffon.

 

A week passed like the blink of an eye. Gabby continued to expand and grow until she was taller than the trees. Twilight was thankful for this degradation of the spontaneous growth, making better use of her time while Gabby sat in the lake. The top of her belly easily broke the tree line, revealing her immense gravidity for any pegasai flying around the forest.

 

Even with her unbelievable height, Gabby's womb still sagged low to the ground. The gigantic swell seemed to scrape the dirt even at full height, forcing the giantess to keep her back arched. Her breasts were as big as hot air balloons resting proudly upon her belly.

 

The lake had become too small for her, forcing Gabby to use the nearby waterfall to clean herself of the dirt, food and breastmilk staining her body. “Ahh...how relaxing...” Gabby cooed as the water tickled her body. Her womb was a flurry of vibrations and kicks as the army squirming inside demanded more food.

 

“Twilight should be here soon. I hope she has something good to eat when she comes by.” Gabby mused as she struggled to sit down. She cradled her belly and began humming to her brood, hoping to calm the storm inside of her.

 

Gabby smiled as she heard the telltale poof of Twilight's magic. “Are we ready to begin?” Gabby asked.

 

“Of course. I'll have breakfast teleported over soon. I wanted to get the usual measurements out of the way.” Twilight reached out with her magic to perform the usual wellness check. Her blood ran cold as a certain something seemed out of place.

 

“Gabby...I don't mean to alarm you...But it's gone.”

 

“What's gone? I'm not missing anything important, am I?”

 

“Not anything that was a part of you BEFORE the growth spurts happened.” Twilight checked and checked but her magic couldn't find it. “Any trace of Gnasher's DNA is gone...your body has finally fused with it.”

 

Gabby looked down at the tiny alicorn with a smile. “So? I wont ever be small again, is that right?”

 

Twilight nodded. “I can't fix you anymore, Gabby. You're now a completely different person than you were before I got you all mixed into this.”

 

The griffon giggled and reached down to Twilight. Her gigantic hug squished Twilight right into her gigantic breasts, making the tiny mare blush like crazy. “I'm not mad or anything. I kinda LIKE being this size. Plus, don't you have a proper sample of the genes you were looking to study with me like this?”

 

Twilight struggled to reply as the mountains of breast flesh had her trapped. “I...I guess...if you don't mind me doing research on you...”

 

Gabby shrugged as she released Twilight from her lewd grip. “It'll only cost you enough food to keep me fed for the day? Deal?” Gabby asked as she put her hands on her quaking stomach as it demanded more.
