Natasha invites her human friend over for dinner. It turns out she wants to ask him something very important to her.

Natasha Flank is a Half Earthpony half Wolf. She lives in her town of Mac Tíre-bhaile, or Mactíre as most of the residence of the town call it. It's a little town just out side the boards of Equestria. Natasha was known in the town as Mare le asal mór, or, Mare with a big rump. Fitting name for her considering her normal phasic. Of course, her name also comes from her power, an ability to cause herself to grow bigger, and that's what her human colt friend is about to find out about.

Furry Growth

Ladgo walks up to the wooden door of the small house on the outskirts of town. He had been invited for dinner at his mare friend's house. The two had been dating for around four months at this point. The two hit it off very quickly after the first time he had arrived in Mactire. Ladgo was an adventure and had wandered a bit too close to the town. The residents, who were wolf ponies, had never seen a human before. So they locked him up in the local jail for the night.

Natasha had seen him being dragged into town and saw how the others reacted and treated him. After a lot of talking, she convinced the jailkeeper to let him free into her custody. The two hit it off well as friends and eventually fell in love, That leaves us here, wear Ladgo stands outside her house as he rings her doorbell.

"Come in!" The sweet but slightly gravely voice of Natasha yells out from inside the house. Ladgo opens the door and enters the house before closing the door behind him. He looks into the dining room to see plates set up for the two of them. One across from the other. He walks into the dining room as Natasha walks in from the kitchen with a waitress dish on her back full of Spaghetti, garlic bread, and steak.

Natasha is a wolf pony like the rest of her village. Her yellow eyes contrast brightly against her black fur. Coming out of her mouth are little white fangs. Her body was small but built strong with her front hooves being replaced with paws. Her rump seemed to be almost the right size for her body and yet still very enticing to look at. That is thanks to her ability to control the size of her body. Her cutie mark demonstrates this perfectly with a silhouette of a pony shrinking.

"That's an intrusting combination of foods," Ladgo thinks to himself as he watches Natasha walk over to the dining table. The two make eye contact before they both crack a smile at each other. She slides the waitress dish onto the table before turning and walking over to Ladgo as he steps into the dining room. She stands up on her hind legs, barely even making it to his chest. She leans against him while wrapping her arms around his body. Ladgo wraps his arms around her and then gently squeezes each other in a warm hug. Ladgo smiles as he gently places his head on top of hers.

"Nice to see you remembered the date," Natasha says sweetly, nuzzling into his chest.

"I would never forget a date with you my love," Ladgo responds as they partially separate to look into each other's eyes. Ladgo smiles down at her as she smiles up at him. The two slowly leaned close to each other's faces without a second thought. Their lips connect as they slowly close their eyes. Ladgo's hand finds it's way up to the back of her spiky mane. He runs his fingers threw her hair as they presently kiss.

Natasha separates first, landing back on the ground on all fours before turning around and walking toward the dining table. Ladgo smiles as he follows her to the table. She makes her way to her side of the table as Ladgo sits down on his side. Natasha sits down as Ladgo helps himself to the food.

Natasha grabs the steak and literally chows down on it as Ladgo eats the bowl of spaghetti with his fork. Ladgo watches her eat as he mindlessly puts food into his mouth. The steak juices run down her chin as she grabs her cup and chugs the milk down her throat. She then goes back to violently eating the steak with her mouth and claws.

"Why do I find this hot?" Ladgo asks himself as he chuckles, eating another fork of spaghetti. Natasha is caught off guard by his little laugh as she was dangling a piece of steak over her mouth with her claw. She swallows it down before asking,

"What's so funny?" While tilting her head to the side.

"Oh, nothing," Ladgo says, looking up at the cute display of a mare that sits in front of him.

"Ookk.." Natasha says suspiciously. She then grabs her empty plate and cup and walks to the kitchen. Ladgo watches her as she was her hips a bit. Her nice curves are accentuated by the motion of her swaying hips. She walks around the corner of the door as Ladgo gets up. He grabs his plate and downs the cup of milk he was given. He then walks to the kitchen where he finds Natasha washing her dishes. He walks up behind her and places the dishes in the sink, making an impromptu hug.

She jumps from the sudden warmth of his body as he speaks softly into her ear. "I don't know why, but you brought me here to tell me something, didn't you?" Natasha shuts off the water and steps away. Ladgo straitens back up as Natasha brings herself the courage to say something.

"let's go into the living room," She says timidly. Ladgo raises a concerned eyebrow as he watches her walk into the dining room and towards the living room. Ladgo follows and the two sit down on the one couch in the room.

"So?"

Natasha looks down at the couch, not able to look at him before asking, "Do you know what claiming is?"

This took Ladgo by a slight surprise. "She's not one to follow tradition, unless this one means something to her," "Ya, I've read about it, but I don't think any wolf pony still does it,"

This makes Natasha a little more worried as she scratches the couch. "Well, I want to ask you if you would like to be my claim?"

"Fuck ya," Ladgo says without thinking. Not that he had to think much about spending the rest of his life with her. "So what does it all entail?"

"First I have to bite you, but just enough to drain blood and turn you into a wolf..." Natasha starts happily but starts to trail off. "If it works," She mumbles to herself before continuing. "Then we fuck each other senseless until we both fall asleep,"

Ladog thinks over the information he has been presented. "The second part sounds fun, but the first sounds dangerous," He inquires.

"Don't worry, it's not that bad," Natasha replies, scooting closer to him. "Just hug me and I'll do the rest." She says, extending her arms out waiting for a hug. Ladgo does as instructed and hugs her. She places her head into the crock of his neck and bits down on his shoulder. He grits his teeth as her fangs dig into his shoulder. Blood drips out as she pulls out. She licks his blood off his shoulder and smiles before hugging him back. "Your blood tests like O-positive,"

"How.." Ladgo starts but decided against that question with another. "So how long till it starts?"

"About a minute if it works on you," Natasha says, pulling away from him before jumping off the couch. "While we wait, let's make our way to my bedroom. We are going to need the padding." She says as she walks away. Her hips still swaying back and forth with every step. Ladgo follows, his eyes transfixed on her nice soft rump.

The two make their way past the dining room and down a hallway toward her bead room. Ladgo starts to feel a tingle in his pants but dismisses it. The two step into the bedroom, which was a mess of books and papers covering the area around the desk sitting in the corner. Natasha makes her way to the bed with her eyes closed. Ladgo watches as her rump grows a little bigger before she opens her eyes and leans against the bed. Her rump sticking off the end. Ladgo had only seen her rump grow a few other times, mostly on accident when she gets too aroused.

She looks back at Ladgo with a smile and lust in her eyes. Before either could do anything, Ladog grunts in pain and collapses to the ground holding his stomick. Natasha quickly rushes to his side as he grunts in pain.

"It must be working, but oh dear I don't think he would be in this much pain." She thinks as she worryingly holds him to try and comfort the pain.

"Ahh! Fuck!" Ladgo grunts before uncurling and convulsing on the ground. Natasha steps back and watches as her worry turns into panic.

"Shit, I might have just killed him. Fuck Fuck Fuck.." Natasha keeps thinking as she paces back and forth in panic. Ladgo finally stops convulsing and just lays there. Natasha looks to see his body had gone through changes. The hair on his head was long and slightly crazier, but that could be from the seizure he just had. His skin had gained a lighter tone to it. His hands wear replaced with furry paws, the hair dissipating the further up his arm it went. Blood slightly covered the paws, probably due to the rapid change. While Natasha couldn't get a good look, it definitely looked like his dick had gotten a change too. There was now a pretty big bulge in his pants.

Ladgo slowly opens his eyes before covering them with his hand.. paw. He slowly sits up and holds his stomick as Natasha gasps in joy before hugging him. Ladgo is too busy looking at his new paw to notice Natasha.

"I thought I killed you for a second!" Natasha says, tears now running down her cheek. "I'm so sorry." She feels an arm wrap around her as Ladgo hugs her back.

"It's ok, I'm still here." The two separate and look into each others eyes. Natasha looks at Ladgo questioningly before wiping her eyes of the tears. She gasped and a big smile formed on her face.

"You have my eyes!" She yells going and grabbing a hand mirror. She holds it up to Ladog's face to see his reflection. His eyes had indeed been changed to the bright yellow ones she had. He smiled and the reflection smiled back.

"I'm going to guess that means it worked," Ladgo says as Natash puts the mirror away.

"Yep, that also means you get a special ability similar to mine because you had to be turned into a wolf.. human?" She says with a little question at the end.

"We called them werewolves," Ladgo says, standing up. Natasha does the same as Ladgo pulls on the back of his paints uncomfortably. "What the fuck?" Ladgo says before unbuttoning and dropping his pants and boxers. Natasha gasps as Ladgo's dick stands straight out. It was about a foot in length and 5 inches in thickness. It was still a standard human dick though, which caused her to look at it funny as her face turns bright red.

Ladgo was more interested in his new tail coming out at the end of his spine. It was a wolf's tail, big and fluffy. It is black with gray strips going down the middle. He attempts to move his tail but just ends up moving his hips, causing his dick to slap Natasha in the face. Literally smacks her out of her staring trance.

She shakes her head before heading over to the bed again and presenting herself to Ladgo like before. She coughs into her paw, getting his attention. "You can work on figuring out your tail later. I have a hunch you now have about 6 hours worth of wolf hormones pumping through you and need some help reliving it." She says in a seductive tone as she wiggles her rump slowly from side to side. Brushing her tail out of the way to show Ladgo her slit that was just dripping and ready to be trusted into.

Ladgo looks over at her rump and instantly his heart skyrocketed. His breath catches in his throat as he stares at her rump. The temptation to fuck her as hard and fast as he could overwhelmed his mind. It clouds his judgment as he walks over to her. He gently grabs her plump rump and squishes it in his new paws, causing Natasha to moan in surprise. His fingers dig deep into her rump before he removes a hand and lines up his dick with her slit.

Ladgo thrust hard and fast into her. The walls of her insides clamp down on his dick as Natasha's moan is caught in her throat. her rump being pushed into her body, the skin acting like jello as it jiggles. Her face turns bright red as Ladgo pulls out. He then thrust into her as the two moan in unison. Ladgo shakes in pleasure from her cunt pulling around his big dick. The most pleasant feeling shoots up his body when he thrust into her.

Natasha moans and grunts as Ladgo falls into a rhythm of thrusts. Her mind starting the become hazy from his dick filling up her tight slit. His dick sliding in and out of her and his power full thrusts plus his new wonderful paws massaging her rump causes her to lose control.

Her rump tingles as it starts to grow. She buries her face into the bed as she lets out a loud high-pitched moan. Her eyes rolling into the back of her head. Ladgo massages her slowly growing rump as he keeps thrusting. Her rump making a nice padding for his hard thrusts. It jiggles with every hip thrust into her.

Ladgo grunts as a familiar build-up starts to happen in his dick. He speeds up his thrust which gets a surprised squeak from Natash before sighing. Her rump starts to grow faster, it's now the size of a beach ball with the consistency of jello. Each thrust brings the two closer to a climax as her rump grows with each pull-out.

"I'm going to cum," Ladgo says before thrusting into her rump as far as he could go. Natasha flings her head back as she lets out a moan. His cum spilled into her, filling her up with his seed. He thrust a couple more times as his climax settles. He sighs as his mind clears up. He pulls out as their cum spills out of her filled slit. Her rump stopped growing as Natasha lays there trying to recover.

Ladgo looks at her as a small smile creeps across his face. His dick hardens again as he grabs her now beachball-sized ass and lifts it up. She squeaks as he pushes her body onto the bed. He places her rump so it's in the air before he claims on the bed. He lines up his dick with her slit again. Before she can ask, he thrusts hard into her. She shivers and moans. Her rump barely stayed up from the sudden weight.

Ladgo leans over her rump with his paws pushing on her back for stability. He thrusts in a way that causes him to just bounce off her big rump. This bouncing just escalates Natash's pleaser. His dick filled her up and the great feeling of every thrust as he bounces off of her before coming back down. Her rump jiggles like jello as it starts to grow again. Ledgo thrusts faster as Natasha's moans keep getting louder with each thrust.

Ladgo goes and lightly bites her ear, causing her to shiver. Her body starts to grow with her rump now. Her rump is so big Ladog can no longer touch the ground and has to rely on his moment he already had to keep thrusting into her big, soft, plush rump.

"Ladgo, keep going." Natasha chokes out. "I'm about to cli. ahh.." Natasha is cut off by her moans as her hips thrust up into Ladog as she cums. This makes it easier for Ladgo to thrust, and before long he starts to cum inside her again. He rests against her back. She was now the size of a big stallion and her rump now the size of two beachballs with the softness of a stuffed animal and the consistency of jello.

Ladgo recovers first as he slides off of her. His mind still slightly a haze as he walks around to her face. She looks up at her tiredly as he lifts her head up gently up to his. He plants a kiss on her lips. She lets out a happy sigh as she pushes into his kiss. He rubs her cheek with his hand as he separates from her, leaving a strain of saliva between them. The two look into each other's eyes before Ladog stands up straight and holds her head.

She looks at his dick that is now in front of her face. She smiles, knowing what he wants, and opens her mouth. He slides his dick into her mouth. He starts out slowly thrusting into her mouth, the warm interior of her mouth feeling nice against his skin. She starts licking the underside of his dick, causing him to let out a moan as he speeds up his thrust into her face. His dick pushed down into her throat, causing her to cough a few times before getting the hang of it.

Ladgo grunts as he feels her thick tongue slide against and around his dick as he pumps his dick in and out of her mouth. She grunts as her rump grows a little each time he thrusts. Her moans of pleasure are split between her massive rump and the dick thrusting into her mouth.

This time it didn't take much time for his climax to rise. Her wraps his arms around her head and thrust into her mouth. The two moan as he cums down her throat. He pulls out after he stopped coming and slumps down onto the bed face up. He takes deep breaths as he tries to calm down his heart.

Natasha recovers from the face fuck before closing her eyes. She starts to shrink back down and stops at her normal size with a little chub left on her rump then normal. She crawls over to Ladgo and rests her head against his chest. He mindlessly wraps his new tail around her body as his arm does the same. The two sit there, enjoying each other just being there.

Natasha looks up as Ladgo brushes the back of her head with his new paw. She looks at him to see a thinking look plastered to his face. She looks concerningly at him before asking, "Are you rethinking this?"

"Not for a second," Ladgo responds almost instantly. He looks over at her and rubs her cheek with his paw. She nuzzels into it happely. "Sorry about the rough sex." He chuckles, "I don't want to hurt you."

"Don't worry, I have a lot of padding," She says, pushing her rump up in the air and wiggling it. The two chuckle before the two lay there in quiet. "What were you thinking about?"

Ladgo takes a deep breath in before speaking. "I'm worried how others will treat you after they know you claimed a human. They didn't like us before, what happens now."

Natasha thinks for a second before nuzzling her head into his neck. "One problem at a time." She says as Ladgo's dick starts to harden again. He chuckles at the remark as she watches his dick throb.

"I think I need a round two," Ladgo says, combing his paw through her mane. She shakes her head from the gesture before looking over at his erect dick.

"I'll handle it this time, you just lay there and enjoy the show," Natasha says, grabbing his body and surprisingly dragging his enter body up onto the bed. Ladgo smiles before shifting into a more comfortable position with his head on a pillow. Natasha claims on top of Ladgos chest with her rump against his dick. She shivers from the huge throbbing dick pushing against her butt. Ladgo grunts and thrusts upwards in response to her rump being pushed against his dick.

"Damit, don't tease me or you might get the pounding again," He says, feeling the haze start to fill his mind with thoughts of rutting her as hard as he could. Natasha cracks a smile and leans down to his ear. Her butt in the air and her chest against his.

"What if that's my goal," She whispers before closing her eyes. She starts slowly rubbing her rump against his dick. In response, Ladgo's hips thrust up into her stomick trying to get the nice feeling of her big rump back. She lets out a moan as her rump starts to grow bigger. Ladgo watches as her rump slowly surrounds his dick with the wonderfully soft feeling of her fur. He wraps his arms around her body as she speeds up her thrusts. Her rump jiggles like crazy with every thrust as it keeps growing. It now stands at the size of a beach ball, and it keeps going.

"Fuck!" Ladgo yells, thrusting up faster while tightening his grip on Natasha. She lets out a high-pitched moan. Her hips slow down and buck back into his dick as she cums onto him. She sighs as Ladgo grunts in disapproval.

"Hold on big boy, just give me a second," Natasha says, pushing herself off of him and staring over him. She smiles manically before pushing hard against his dick and thrusting her rump up and down his shaft fast. Ladgo gasps in pleasure as Natash's rump grows to now the size of two beach balls as her body starts to grow with her rump.

Ladgo grabs her rump and thrusts up as he moans. His cum shooting out and landing on her back. He stops coming and the two rest for a second, staring into each others eyes with love and lust. Smiles crept over the two's faces slowly. Without a word, Natasha stands up and turns around. She lays down on his chest with her huge double beach ball-sized rump in Ladgo's face, with her cradling his dick with her arms.

Ladgo slowly slides his hands up her rump, lightly pushing into it. She lets out a light moan as she starts rubbing Ladgo's dick with her paw. His hands sink into her nice and soft rump. He pushes his palms into her cutie mark while licking her dripping wet slit. She lets out a moan as she licks up the side of Ladgo's dick. He shivers as he basically french kisses her pussy.

Natasha takes in his dick into her mouth as she moans. The vibrations and her warm mouth cause Ladgo to moan into her rump and thrust up into her mouth. He speeds up his massaging as her rump starts to grow again. It getting bigger and squishier. It starts conforming around his head as Natasha starts bobbing up and down on his dick.

Natasha's hips start bucking back into Ladgo's face as her rump starts to get to big for his hands to massage the enter thing. His hands sink deeper into her fur as her rump keeps growing. Ladgo gurns as he cums into Natasha's mouth. Natasha smiles and chuckles at how fast he cam. She pull off and looks back at him.

"Is that all you got?" She asks. This makes Ladgo angry, causing him to speed up his efforts. Surprising Natasha, causing her body to spasm and her to moan as his hands work at the base of her tail. Ladgo chuckles at the mare spasming on top of him just because he touches one spot. He keeps working at massaging the base of her tail while sliding his young along the inside of her tight slit.

It wasn't long before she went over the edge and came onto his face. He pulls away and spits out the bitter mare cum. The two lay there as they recover from the sex. Natasha shrinks back to normal before turning around and cuddling up to Ladgo. Placing her head under his chin.

"Good night Ladgo Flank,"

"So I'm taking on your last name?" Ladgo asks tiredly.

"We'll talk in the morning after morning sex." She says, closing her eyes and nuzzling into his body. He hugs her tighter and the two drift off to sleep.

Author's Note

Did anyone make it to the end? Because if you did, congratulations, you just read one of the worst stories I think I've ever made. This thing has been finished for well over a year and now I've just decided to post it.
