Hot Swap

“Didn’t work huh?”

Applebloom sighed and sank into the plush sofa of Garden Delights outdoor seat. She was enjoying a light brunch with Scootaloo and Sweetie Belle on their off day from school. Tomorrow they’d be on and would all have to pile in to class. For now, the trio could kick back and relax. Or at least two of them could.

“Nope, nothin’ doing Scoots,” said Applebloom, adjusting the sun hat Sweetie had lent her. “Are y’all really not feeling this heat? I’m dyin’ out here!”

Sweetie Belle rolled her eyes. “This is one of the most outright pleasant days we’ve had the past two weeks. It’s sunny but not hot, breezy but not cold. I don’t understand why you’re complaining so much.”

“Are ya sick?” Scootaloo asked, pouring another glass of ice water to share.

“Can’t be. I swear it’s just me bein’ out here,” complained Applebloom, graciously accepting the tall glass and downing half of it.

Scootaloo sat up in her seat and crossed her long legs. At a lofty six-foot two she was growing into a sight to see with her athletic physique and pert breasts. The black sports bra she wore contrasted nicely with her low cut white crop top , which showed off her hard-earned six-pack abs. They flowed right down into her matching black spats which so perfectly hugged her muscular ass they might as well have been painted on.

“If you’re sick just go to the doctor,” suggested Scootaloo, eying her friend with concern..

“Ahm. Not. Sick,” said Applebloom tersely. “Jus’ hot under the collar is all.”

Sweetie Belle giggled, her full bosom bouncing in the confines of her lilac sundress. “Is hot under the collar what you were doing yesterday with Rumble?”

Applebloom eyed Sweetie suspiciously. “How’d y’all know about that?”

“Your sister,” said Sweetie, sipping her lemonade. “Said you two may or may not have been fooling around in the old clubhouse?”

“Ugh,” Applebloom pointed an accusatory finger at Sweetie. “YOUR SISTER is a bad influence. Now she’s got mah sister gossipin’ too!”

“So… were you fooling around?” pressed Scootaloo, folding her arms.

“Nooo, Ah ain’t movin’ on your boy,” Applebloom replied.

Sweetie Belle laughed again and Scootaloo blushed. “Okay good.”

“You know he’s not your boy until he asks YOU out,” reminded Sweetie Belle.

Scootaloo shrugged. “He will. Rumble totally wants me.”

“Well,” Sweetie Belle put her teacup down. “I know Terramar wanted me because the last time I met with him… he told me.”

The other two girls bolted up in their seats.

“Really!?” they said in unison.

Sweetie Belle blushed and nodded.

“Awesome!” they congratulated Sweetie Belle and settled back down. “Anything else happen?” asked Scootaloo.

Sweetie Belle blushed madly but didn’t say anything.

“Did y’all kiss him?” asked Applebloom, feeling a creeping warmness starting to bubble up inside her.

Silence.

Scootaloo whistled long and low. “You HAVE to tell us! Tell us everything!”

“Okay, it all started when Terramar came to visit last weekend and I told you girls I was having Sunday along to myself. I had written him a letter earlier in the month to invite him. So he gets here and oh my gosh girls he got so tall,”

“How big is he?” asked Scootaloo.

Sweetie Belle tapped her chin. “Oh gosh he had to be like over seven feet tall or something like that. Absolutely bigger than your brother, Applebloom. Where he lives they ALL get that tall.”

Applebloom gasped.

“Not as beefy though. But he was still strong. Anyway, so he comes over and we’re just hanging out and enjoying each others company talking about stuff and we were really hitting it off! I haven’t seen him in a few years and of course I was talking a bit about him! His height, how he looked… You don’t just ignore a friend of yours changing like THAT after all,” she blushed, giggling softly. “So he started complimenting meee and we decided to take a dip in the lake because it was hot out.”

A rakish grin crossed Scootaloo’s face. “You totally wanted him at that point. Don’t lie!”

Sweetie Belle looked away sheepishly. “I put one of Rarity’s bikinis instead of mine. The purple diamond pattern ones that I wore that one time at Diamonds pool party.”

Applebloom gulped and nodded. The image of her in that suit resurfaced in Applebloom’s mind and was promptly burned into the forefront. That bikini was two sizes smaller than what Sweetie’s curvy body needed. It was a last minute mistake Sweetie had made and strapped over her plump assets was borderline obscene. The fabric didn’t even fully cover her pink areola and the bottoms were nearly threadbare. Every boy at the party was practically glued to Sweetie that day.

“Okay you know you wanted him,” affirmed Scootaloo, leaning in closer. “Then what?”

“Well,” Sweetie was almost beet red at this point, and began fanning herself with the drinks menu. “He had on his trunks and we took a dip together. I think he caught on as soon as he saw my suit but I wasn’t being exactly subtle. So we’re swimming along together and chatting and being like, play frisky. I decide I want to jump off that flat rock near the northern part of the pond but we were already splashing and the surface was slick. I fell.”

“And?” Applebloom felt a tingling in her loins.

“He caught me in his arms as I hit the water,” Sweetie said dreamily, twisting a lock of her curly hair. “He asked if I was okay and I said yes and I could feel that one of my breasts fell out of my top but we didn’t say anything…we were looking at each others eyes and then we leaned up and kissed hard.”

“Awesome!” said Scootaloo. Applebloom said nothing, but her mouth felt very dry all of a sudden and her groin ached.

“We kissed for a few minutes and he was such a good kisser! Like, actually taking my breath away girls! I was kissing him hard and then we changed around our position where he was holding me up by like, under my thighs, and I could feel my breasts squished up against his chest. It was so romantic and sexy. And slippery! We were all over each other for like five minutes! And then-”

As Sweetie Belle prattled on Applebloom became more and more aroused than she already was. It felt like her whole body was tightening up like a spring in anticipation. Just how lewd did Sweetie Belle get with Terramar? Was he really that into her? Sweetie Belle’s body was sexy sure but that sexy? Applebloom never got her hands on Sweetie’s tits but maybe she should to-

Applebloom shook her head. A sharp pain flashed in her skull for a moment and then vanished.

“-then I could feel… it. Poking me a little in the back while he was standing behind me in the water.”

“Holy Celestia keep going!” Scootaloo buzzed her wings. “This is so hot!”

“Yea, it sure is,” grunted Applebloom, leaning forwards and adjusting her clothes. Why were they so tight on her all of a sudden? Her sleeves were rolling up and her shorts felt weird. Like they didn’t fit right.

“So I ask him how big it is and he goes ‘would you like to find out’ and I say yes, so he picks me up under the arms and then he slides his… cock in between my legs while he’s holding me, so I’m sort of sitting on his penis but not with my full weight,” continued Sweetie.

Scootaloo’s jaw dropped.

“It had to be two feet long and thick at the base like a cola can,” Sweetie whispered, "it was even thicker at the base between my legs. So, I start touching it and stroking it and I keep guessing how long it is but I kept guessing wrong. And it’s so warm and hard and throbbing between my legs, and he’s dripping stuff into the pool from the tip. Then Terramar asks if I want to feel how big he is.”

Applebloom felt like she was snorting steam at this point. Her head was swimming and her heart pounding and she wanted to rip her damn forsaken ill fitting clothes off. She could smell how aroused Sweetie, and especially Scootaloo was. The smell was delicious and it was making her drool. Appleblooms groin was twitching madly and it took every ounce of willpower to not reach down there in public.

“So I slide off him and I pull myself up on the flat rock and lay down on it, and stick my booty in the air and swish my tail at him. He comes over and pulls the bikini bottom to the side and he puts just the tip inside of me and girls it was so BIG right off the bat. To just have the big tip in me and I was squealing.”

Applebloom exhaled and reached over to grab a napkin to dab at her forehead and paused to look at her arm. Was she always this buff? She looked like she had Scootaloo’s physique. Applebloom checked her other arm and noted the same, seeing that her sleeves had rolled up almost to the armpit. And her shirt was ridden up too…

“Then Terramar leans back and pushes almost the WHOLE THING inside of me and I lose my mind girls,” Sweetie fluttered her eyes shut and leaned back in her chair with a dopey smile on her face. “He’s pushing into me real nice and slow and squeezing my butt, rubbing my back and playing with my breasts. Celestia it was amazing! I had to stuff my hair in my mouth so I wouldn’t scream so loud. He was SO BIG. His penis filled me like, really. I could feel every vein on that shaft of his.”

Applebloom slid a hand down her front. Abs? When did she get abs? And what was that in her pants? Did she have a baton in her pants or something from earli-

Applebloom froze in her seat. She had a penis in her pants.. That was HER penis.

“-and then after my second orgasm he held me tight and he came inside of me and then I came again-”

The shorts Applebloom had on ended about mid thigh and thanks to her height increase and new muscle they had become uncomfortably tight. Her growing cock slipped out of her panties and the tip was snaking out along the inside of her thigh. This was really bad. She had to jet before the girls noticed.

“Did he get you pregnant from that!?” whispered Scootaloo, on the edge of her seat.

Sweetie Belle shook her head. “Noo, I wasn’t in heat. But could you imagine ME pregnant? I would look terrible in this dress!”

Applebloom did imagine Sweetie Belle pregnant: Plumped up tits resting on a rounded white belly, widened hips and ass, donned in an amazing outfit designed by her sister that showed off her motherly body.

The lurid thought sent a short wave of growth pulse through Applebloom’s hardening body. Her new cock stiffened and grew in length and girth; warm, wet sticky liquid oozed from the tip. In another minute her clothes were going to rip right off and then she’d be exposed.

Being at the edge of the booth was Applebloom’s only saving grace. “Scuse me,” she grunted out before sprinting to the bathroom in a hectic trot.

“What’s up with her?” asked Sweetie Belle, peering at Applebloom disappearing into the mares room.

“Dunno. Probably because she ate too much brunch,” Scootaloo glanced disapprovingly at the pile of dishes. “She’s lucky that french toast was all you can eat today. Anyway, did you go down on him too?”

Soon as Applebloom slipped into the ladies room she latched the door behind her with a loud CLACK. Lucky her it was a single pony restroom and not a row of stalls. Applebloom awkwardly waddled over to the sink and stood up straight to survey the damage. She winced at the sight of herself.

Where a slim young mare once stood was now replaced by a taller, beefier stallion. Muscular pecs stood in place of her once small undefined breasts and were comically stretching out her now totally useless bra. The hem of her shirt fell right above her bellybutton and new row of abs, leading down to her… it wasn’t even worth calling a bulge at this point. Her fat baseball sized nuts were packed and clearly outlined by her tight shorts and worthless panties, unceremoniously shoved aside by the growth of her ridiculously big penis.

Her cock was pulsing urgently against her inner thigh and drooling precum onto the floor. It was as long as her new, muscled forearm and almost as thick. A few light splotches decorated the dark shaft and was criss-crossed with big noticeable veins.

“Consarnit!” Applebloom said. She gasped and put a hand over her mouth. That voice wasn’t hers. It was deeper! She sounded like a boy! Like a manly stallion.

“Lousy potion was botched beyond belief,” groaned Applebloom, wincing at her new, deeper voice. She carefully slipped her bra off without taking off the shirt (mostly because she felt it would be impossible to slip back on) and proceeded to remove her more elastic spats. Applebloom paused for a second, then removed her signature bow. Right now she didn’t want to be recognized. Tossing her female undergarments aside Applebloom marveled at the size of her erect cock in the mirror. It had to be almost a foot long.

“The hay am ah gonna do…” she groaned, one hand still clutching her shorts. They had to go back on, but not while her massive new cock was at full mast. If it were soft she could stuff her junk into the spats and make a break for it before her friends could realize what was going on. The new muscles in her calves and thighs promised speed and power. But first the erection had to go.

Oh!” Applebloom facepalmed. It hit her! All she needed to do was cum. In Sex Ed Applebloom remembered that after mating the male organ would soften after orgasm. Knowing that this could get messy Applebloom walked over to the toilet, her heavy hooffalls clicking against the tile, and raised the lids.

Having heard more than one secondhand lewd story Applebloom wasn’t unaware to stallion parts or how to please them. She gripped her shaft tenderly, feeling the welcome sensation of her fingers against the warm, fleshy skin. With a slow motion she glided her palm up the length to the tip and down to the medial ring. It felt so good already! Applebloom moaned deep, repeating the motion a few more times.

The tip of her cock was leaking even more precum now and helped lubricate her shaft. Applebloom could feel an orgasm building fast. Much faster than as a mare and Applebloom almost doubled over at the powerful sensation in her loins. It was happening that quickly! Which was fine by her. The faster she blew her load the faster she could get out of here. It felt like she was almost there. Applebloom changed her position to point her throbbing cock at the toilet. Just a little more tugging

Knock Knock Knock

“Applebloom? Are you okay in there?,” Sweetie Belle said through the wooden door, “If you want I’ll come in and like, hold your mane back or something?”

At the sound of Sweetie Belle’s sonorous voice Applebloom flashed back to the image of her in that tiny bikini, and the still fresh in her mind story of being fucked by Terramar. Her balls tightened and her shaft surged.

“Uuuhhhhnnnn,” she groaned low and loud, her cock lurching and firing jet after jet of hot cum straight into the bowl. Each long strand of cum was punctuated by a noticeable GLEWP GLEWP from the force of her orgasm.

“Oh my! Uhh, I guess you weren’t throwing up!” Sweetie Belle said, her voice filled with disgust. “Feel better in there! Uhh, see you later!”

Applebloom’s orgasm continued, but instead of petering out it got more forceful. She forced her eyes open just as the first long tear ripped straight down her expanding back.

“Ohh! Oh FfFfFfuuuuck,” she grunted, her body surging with growth. Her muscles thickened and swelled, her limbs lengthening, chest swelling, balls swelling. Every spurt of her jerking cock expelled more and more cum into the bowl. That too was growing. Every second it was getting thicker and longer and spreading her fingers wider apart.

R-R-R-R-R-IIIP

Applebloom unconsciously flexed her body and her shirt completely tore in two long pieces at the front, followed by her chest and sides when she reached back to feel her bare exposed coat.

Finally, her cock lurched a final time and the deluge of jizz ended. A semi-clear droplet formed at the tip and dripped to the floor.

“....fuck.” Applebloom said morosely. The toilet bowl was filled with her cum. Not to the point of overflowing, but definitely to the point of not flushing down. If this were an outhouse she’d be perfectly fine. The wall behind the toilet was blasted with twin ropes of jizz right when she’d flinched at her shirt ripping. Otherwise all of her cum made it to the bowl. She looked at the now much beefier cock in her hand. It looked like it doubled in size. Her fat nuts had swelled to the size of softballs and felt much weighter dangling between her oaken thighs.

Applebloom gulped and walked to the mirror.

She had to step back a bit to see herself now. It looked like that orgasm shot her body up another several inches. The muscular physique she sported now more than matched her brothers. Perhaps even better, Applebloom noted, watching the melon sized bicep pop up under her coat. There didn’t seem to be an ounce of fat on her now. Her face had changed too, becoming more masculine and defined. Applebloom ripped her tattered collar off her thicker neck and threw it to the side to admire this new body completely bare.

“If only this were for the right one,” Applebloom muttered. Sounded like her voice dropped another octave too. She grabbed her spats and gingerly put them back on. Thanks to the miracle of spandex she managed to stretch the bottoms back on. It was worse than before of course, considering how obscenely her flaccid cock and balls bulged out from her groin. The top of her flaccid cock was even visible as there wasn’t enough fabric to cover everything. It only served to prevent her package from bouncing around all over the place as she ran.

Applebloom grabbed her clothes. Counted to three in her head and bolted out of the bathroom stall towards Sweet Apple Acres.
