Pipp's Growth Spurt

Pipp flies through the air with the wind in her mane and the sky below her as she spins on her way to the Zeypher Hights museum. Her mother wanted an old book about flying to help teach the pegasus how to fly. Pipp glides down to the ground and lands in front of one of the biggest buildings in the city. Standing almost the same size as the royal castle, the museum stands as the oldest building that holds the oldest relics of their past.

Pipp walks in with a skip into the big open area of the reception. In the middle sits around desk, and in the center is a red mare with a slightly spiked pack mane. Her hair is red with dark blue strands sticking through like lightning. She looks up at Pipp with a warm smile. Her eyes light blue with youth, but her wrinkling skin says otherwise.

"Good morning Princess Pipp! How are you today?" The mare asks, putting down the book she was reading.

"Good morning Mrs. Artifact!" Pipp says happily, walking up to her.

"Please, call me Acid. No need to be formal to me. Now, what are you here for?" Artifact asks.

"Mom sent me to get a few old books on flying to see if we can teach the other pegasus to fly," Pipp explains.

"Door 4 on the second hallway on your left, sweetie," Artifact says, pointing down a hallway. Pipp nods and flies down the hallway. She turns the corner and opens the door into a room lined with books and artifacts standing in the center with glass coverings. Posters of the wonder bolts, Twilight, a unicorn named Acid Flask, and other students of Celestia plus other figureheads posted around the room. She walks to the bookshelves, only glancing at the set of goggles lying in the glass pedestal. She reads over the book covers and starts grabbing a few before something catches her eye.

One of the pedestals didn't have a glass covering. Sitting on the top was a black collar with a blue crystal dial-looking thing and blue computer-like lines coming out from the stone. She retches out and grabs it and looks at it.

"That's a cool collar, I bet Zipp would like it." Pipp looks to the door and around the room before stuffing the collar in her saddlebag before walking out to go check the books out.

Pipp drops off the books with her mom and takes her new collar with her to her room. Zipp wasn't home yet, so she decided to wear it. She puts it on and looks in the mirror.

"Not my style.. yet I don't feel like taking it off." Pipp thinks, her hoof inches away from taking it off.

"Breakfast is ready!" Her mom yells, cutting off her thoughts. "Pipp, do you know where your sister is at?!"

"I think she's with Hitch and Sunny this morning!" Pipp yells back as she walks out of her room.

"Do you think you could call her?!"

"Her phone might be turned off, but I can try," Pipp says, walking into the dining room where her mother sits, already eating the pancakes prepared by their staff.

"Just make it fast, food is getting cold," Her mother says as Pipp texts Zipp. She stops before she hits send. Her entire body feels like she is shocked by lightning, but instead of pain, it is pleaser. She drops her phone as she stares at the ground as her body feels consumed by the pleaser. her vision and body are consumed by blue as magic wraps around her body. The magic and feeling only last for a second before fading away. Pipp stands there staring at her phone on the ground.

"You ok Pipp?" Her mother asks kindly. Pipp blinks a few times then picks up her phone.

"Ya, just dropped my phone," Pipp says with an awkward smile. She walks over to her seat and sits down. She shifts a bit as she feels a bit different. She shrugs it off and hits send on her text to Zipp. She places the phone next to her plate and starts eating.

"I have a lot of stuff to do today," Her mother says. "I need to do it fast for the party in a week,"

"Oh ya! Zipps air show she's been working on..." Pipp's breath catches in her through as the same blue magic consume her body but for only a second. Her body shivers in plasear as she feels herself getting taller, or was her butt getting bigger. The magic stops and she turns away from her mother to hid her blush. She looks down to see that, in fact, her rump had grown slightly.

"What the hay!? It must be the collar," Pipp thinks before returning to eating. She quickly finishes up, and grabs her phone before heading towards the door. Her mother's voice stops her in her tracks.

"Pipp, were are you going so fast?" Pipp turns around to face her mother with a smile.

"I need to find a dress I'm going to wear to the air show. It is her first after all, we need to look our best..." Pipp slightly drifts off as the sensation of the magic starts to return. Pipp quickly ducks through the door, accidentally pumping into Zipp on her way out.

"Hay Pipp, I was thinking that..."

"No time to talk now!" Pipp yells to her sister as she bolts down the hallway and into her room. Unknowingly leaving Zipp, Hitch, and Sunny all standing there confused.

"That doesn't sound like her," Hitch says, breaking the silence.

"You two go into the dining room, mom probably has breakfast for you if you ask," Zipp says, walking down the hallway. "I'll cheek on Pipp," Hitch and Sunny look and each other and shrug before walking into the dinning room.

Pipp crumples to the floor right when she closes the door to her room. She lets out a happy little moan as the blue magic causes her rump to grow again. Her slit dripping with pre cum from the pleaser of the growth. She stands up after the magic has stopped and looked at her self in the mirror. She had in fact grown a few inches, and her plot had become more plump then it normally was.

before she can do anything els, Zipp knocks at Pipp's door. "Hey Pipp! You ok in there?!"

"Ya! jut trying on dresses for your air show in a week!" Pipp replies back.

"Ok, just making sure you weren't in heat yet." Zipp says back. Pipp rolls her eyes at Zipp even though she couldn't see it. "Sunny and Hitch are here, I was thinking we could show them around the city later if you hurry fast enough,"

"Sounds good, just give me a few minutes and I'll.. be.. out..." Pipp's words start to falter as the growth magic gains control again.

"What keeps triggering this?" Pipp thinks as she watches in the mirror. Her plot grows up and out as her body slightly grows to accommodate the new size rump. The magic stops as Pipp placs a hoof on her new hindqurders. Her hoof slightly squashes into her plot, causing a nice pleasurable sensation to shoot through her body. Not as good as the growth, but it still felt nice. Her cum sliding down her leg caused her to shiver.

"Ok what to wear?" Pipp says, slightly louder than normal to see if anyone was listening. She waits till she hears Zipp's hoof steps walking away from her door. She sighs before thinking about what keeps triggering the spell.

"The only word everypony has said that is the same is fast," Pipp says smiling. She stands there and waits as the magic again grips her. She lets out a happy moan as her plot grows again, with even more pleaser. Her butt feels like it's being inflated from the inside out. Her rump is now two times the size of her normal rump. She was also almost 6 inches taller than normal to accommodate for the new rump. The magic stops as she admires herself in the mirror.

She sits down, and to her slight shock, her butt gives very little like a bowl of jelly. She lets out a slight moan when she sits down too. The cold floor touching her warm body plus the new plush rump caused her to be shot with pleaser.

"I could get used to this," Pipp thinks as she shifts her bodyweight around, causing her butt to squish. She stands up as she gets an idea. She pulls out from under the bed a toy horse cock and a somewhat sexual picture of Hitch from one of his calendar shoots. She suction cubs the dick to the wall while pacing the picture on the ground. Pipp turns around so her butt was now facing the dick.

She smiles and waves her butt around, watching it giggle as she says, "Do you like what you see Hitch?" She imagines the Sherif staring at her new assets, with his dick sliding out of its sheath in excitement. She imagines him mounting her as she slides the horse cock into herself. The dick pushed apart her slit and butt cheeks, causing her to moan. "You have such a big dick Hitch," She chuckles at the accidental rym. "Good for a big rumped mare like me. Now show me what you got and fast," Pipp says, thrust back into the cock. Her butt hitting the wall, causing a slapping sound and for her butt to giggle. She moan as the dick slides into her, expanding her inside as the sensation of the magic returns to her.

She pulls out and thrust again as her butt starts to grow again. Her ass giggles and grows with every thrust she puts into the wall. She looks down at the picture, just imagining the station rutting her as she grows. "Faster," Pipp says as she picks up the pace. Her butt now four times the size it was. The wall craking from her rumps thrusts into it. She also now stands at a foot taller then normal. She moans and shakes as her climax starts to build up inside of her.

"Yes, faster sheriff," Pipp squeaks as she thrust faster. Her butt growing with every thrust, causing her to moan as the paint on the wall chips off from the force. She thrust one last time into the wall and lets out a loud moan as her cum spills out onto the wall. She takes a breather as her cum spurts out.

She is unable to enjoy the after glow when a knock at the door and a surten somepony's sweet deep voice comes right after it, "Pipp, you still in there?" It was Hitch. Pipp quickly slides off the dick and grabs it off the wall with a pop she hopes he didn't hear. She slids the picter and socked dick under the bed and quickly grabbed a towel as she yells, "Ya, just give me a second!"

"Zipp was wondering what is taking you so long. She sent me while Sunny and Zipp get a head start," Pipp places the towl in the landery bin as she gets and idea from the new knowledge that they are alone. She grabs her ear rings and slides them under the desk.

"Hitch, could you come in. I need help finding my ear rings," Pipp says, walking over to the door and opening it. Pipp smiles at the yellow earth pony standing at her door.

"Sure, but we should go soon so we can catch up with the others," Hitch says, walking into the room. Pipp closes the door and locks it with out him know. She notices she is slightly taller then him now. The two look around the room for her ear rings. Pipp bends over, keeping her butt in the air as she looks under the mini-fridge in the corner. Hitch looks over at her rump, causing him to blush and turn away. His dick slitly slids out at the sight of her. Pipp stands up and turns around to see Hitch looking under the couch. Pipp smiles to see his dick out, but not hard yet.

"Got ya," Pipp thinks before walking over to the desk. She beds over the same way as she grabs the earrings and yells, "I found them!" She stays down for a few seconds as Hitch turns to her.

"Good now we.. can..." Hitch trails off as his dick becomes hard at the sight of her rump up in the air for him to see. Her slit barely visible from behind her tail. Pipp stands up with the blue ear rings now in her ears. She turns to see Hitch's face bright red and staring at her butt. His dick now completely hard. She smiles and wiggles her butt from side to side to snap him for his trans. He shakes his head and looks up at Pipp.

"Maybe we should take care of something else first," Pipp says seductively. Pipp starts walking forward towards him while swaying her rump back and forth slowly. Hitch in surprise tries and fails to step back, causing him to fall onto his butt. His dick now fully visible and sticking straight up.

"W-what about Sunny and Zipp, we need to meet up with them?!" Hitch squeaks out in embarrassment.

"They can waaiiitt..!" Pipp slips and falls face-first into the ground with her rump in the air. Pipp shakes her head as hitch stars at her rump.

"Fuck it," Hitch wipers and stands up. He walks paster her. She thinks he is leaving but he walks behind her. "You sure about this?" Hitch asks, placing his front hoof on her rump. They compress in, causing Pipp to shiver in pleaser.

"Please, be fast with it. You and I both need it so hurry up," Pipp says as the magic causes her to grow again. Hitch goes oblivious to it as he slides his dick into her. She gaps then moans as his hug dick slides into her, feeling like nothing she has ever felt before. Hitch is now barrier hip dep into her with her plot surrounding his hips. He leans forward and places his hoofs on her shoulders as her wings pump out.

"Ready Pipp?" Hitch asks. Pipp nods yes right before Hitch starts thrusting hard into her. They both grunt and moan as the pleaser shoot through there bodies. Hitch's dick slides against Pipp's tight walls and his hips hit her rump with every thrust. Pipp is in heaven, Hitch's dick is nothing like she has ever felt before. His dick pushes against her walls hard with every thrust. His hoof dig into her shoulders causing pleaser to her wings, and his hips giggling her and her butt.

The two stay like that, both in a heaven of pleaser. Hitch starts to come over the edge, as he grits his death her yells, "Pipp, I'm going to climax!" Pipp is unable to hear as she climaxes first. Her cum causing his dick to become more slippery against her walls. Hitch grunts and thrust into her as he releases his cum into her the two lay there as they enjoy there after glow. Only one question crossing Pipp's mind. "Did you just say climax?"

Hitch think for a moment and relies how stupid that sounded. The two lagh as Pipp's mother lisens from out side the door.

"Good to know she finally found sompony to be with," She think to self before walking away from the door so they can have some real privet time.
