Twilight has a problem. It's her new dick.

While perusing through a book of spells Princess Celestia has sent her, Twilight thoughtlessly activates one of them and finds herself with a new appendage.

What is she going to do with it?

Trigger warning: Fuck you, you're going in blind.

In Which Twilight Grows A Cock

Twilight Sparkle sat at the desk in her study, wearing a red bra and matching panties. It was her home, she figured, so she should be able to be in her underwear in her own study. And it’s not like Spike wasn’t used to it, anyway, being her number one assistant for all of his twenty-two years of life. He had grown into a fine adult dragon, slightly taller than herself at this point in his life and rippling with muscles.

Must not think those thoughts about Spike. He’s like a brother to me.

Shaking her head at the intrusive thought, she flipped through the pages of a spell book she had recently received from Princess Celestia. It had come with a warning hand-written by Celestia herself that the spells in this book were not to be taken lightly. Twilight snorted at the thought of it.

As if I would be so careless.

She carefully perused each page, leaning back in her chair with her legs crossed, holding the book up in front of her with her aura. Most of the spells looked boring… but there was one that caught her interest. She set the book down on the desk in front of her and hunched over, mumbling the incantation aloud.

Interesting spell. I wonder what it does?

Her question was soon answered as, to her surprise, she felt a roiling in her loins as something expanded out of it, pushing her panties to the side and… throbbing with excitement. She felt her breath catch in her chest and looked down slowly.

In between her legs stood a large erect penis with a flat head.

She blinked, breathing heavily. She knew she should do something, but her thoughts seem to be slow in coming to her. She snapped her fingers as it hit her.

Measurements!

Twilight grabbed the measuring tape located on her desk for measuring emergencies and unrolled it over the length of her new dick.

Alright, twelve point four three inches long and… seven inches in girth.

Smiling, she rolled the measuring tape up and placed it back on the desk. She then went back to her reading, pleased with the progress she had made. Reading was becoming increasingly difficult, however, as the large penis between her legs throbbed and pulsed, annoying her with its presence. Still, she grit her teeth and trudged through the book.

After a while, though, the penis’s presence became too much to ignore, grunting as she slammed the book shut on the desk and stared at her new phallus.

Maybe I should do something about this.

She quickly licked her hand and stroked her member, shivering in the sudden pleasure which caused her to stroke more vigorously. On and on she stroked, the pleasure building up inside of her as she slowly approached her limit.

But it never came.

Frustrated, she rubbed it even harder, the ecstasy of orgasm still escaping her. Her eyes were tearing up from the overload of pleasure as she grabbed it with her other hand and furiously masturbated herself with both hands. To her… something—the word escaped her at the moment—she just could not ejaculate, despite how hard she pleasured herself.

Alright, time to apply some real pressure.

Twilight hesitantly removed her hands from the pulsating cock between her legs, created a sleeve of sorts with her magic, and slid it over her penis, shuddering as the warm energy tightly hugged her new phallus. The vise-like grip of her own magic was intoxicating as she slowly slid the sleeve of magic over her cock, building up the pace as tears streamed down her face from her failure to ejaculate.

She gripped her cock in her aura even tighter and violently jacked herself off as quickly as she could, electric bolts of pleasure shooting through her brain as she drooled from the sensory overload.

Why… why… just please!

Her begging was for naught. Her penis refused to orgasm no matter how much pressure or how vigorous the technique. But it was taunting her with the promise of sweet release if she just tried a little harder. So, with her face covered in tears and drool sliding down her chin and dripping onto her stomach, she continued to masturabate away.

Her concentration was broken by a loud rapping at her door.

“Twilight? It’s Apple Bloom. I was wondering if I could come in and borrow a few books on potion making.”

Twilight quickly dispelled the sleeve, held her mighty cock between her legs, and hid it as best she could under the desk.

“Eh heh heh, sure, Apple Bloom, come on in.”

The door creaked open and revealed Apple Bloom wearing a green tee that hugged her breasts and jeans that wrapped around her hips, as well as a cute smile across her face. She waved at Twilight, who waved back.

“You hot or something? Because you seem to be blushing something furious.”

Twilight giggled. “No, Apple Bloom, I’m fine. Just… come in and take what you need.”

“O… kay,” Apple Bloom said as she raised an eyebrow and walked over to the bookshelf, her firm posterior catching Twilight’s eyes for reasons unknown to her. Apple Bloom examined the book titles, leaning over and stretching out the material of her pants, much to Twilight’s confused delight as her erection pulsed teasingly under her legs.

This is odd. I’m not normally attracted to mares. Maybe this penis did something to my brain chemistry?

Apple Bloom sighed as she pulled out a text and opened it. “Ah, this should help.”

“W-what is it, Apple Bloom?”

“It’s the book I need. You see, I’ve been trying to penetrate to the core of this problem I’ve been having” —Twilight’s cock twitched— “and I’ve been thinking long and hard about it”—Twilight’s cock twitched again—”and I think with this book, I can finally grasp a firm understanding of the solution.”

Twilight’s cock pulsated again at the words which were inadvertently teasing her.

“That’s… that’s nice, Apple Bloom. What’s the problem?”

Apple Bloom giggled. “Animal husbandry.”

Twilight gripped the edges of her chair as her cock screamed for attention. “That sounds wonderful.”

“Not really. I mean, I’m just trying to increase bovine fertility so that I don’t have to jam my hand up a cow’s snatch anymore than I have to.”

“That’s… huh.” Twilight bit her lower lip.

A cow’s snatch doesn’t sound so bad right about now.

Apple Bloom arched an eyebrow at Twilight. “You sure you’re okay? You’re sweating awful fierce.”

“Y-yeah, A-Apple Bloom, I-I’m f-f-fine…”

“And you’re stuttering,” Apple Bloom said as she slowly crept towards Twilight, “you never stutter.” Apple Bloom leaned over Twilight and put the book on the desk, the scent enticing the new cock to beg for contact—anything to get Apple Bloom to touch Twilight. Apple Bloom then leaned back and crossed her arms. “Alright, what is it?”

“It’s n-nothing—”

“—cut the shit, you can’t pull one over on me. Now what’s going on?”

“It’s just… it’s just a little embarrassing.”

Apple Bloom snorted. “Like that matters. You were there when I was blubbering like a foal after Featherweight dumped me. That was embarrassing.”

Twilight pressed her eyes shut.

I guess I could tell her. She has been my student for… a while.

Sighing, Twilight pushed out the chair and stood up, releasing her new cock from its confines. She then slowly turned around, causing Apple Bloom’s eyes to bulge as her jaw dropped.

“This is my problem,” Twilight said with a hint of guilt in her voice.

“Holy Celestia, that’s a big dick,” Apple Bloom said.

Twilight chuckled. “I guess it is. But that’s not the problem I’ve been having.”

Apple Bloom blinked, her eyes locked on the phallus. “It seems swollen,” she said as she licked her lips.

“Yeah,” Twilight said, “it’s probably swollen because I was masturbating for a good while before you came in.”

“Then… why did you let me in?” Apple Bloom asked, her eyes locked on the giant penis twitching before her.

“Because I just couldn’t ejaculate. No matter what I did or how hard I did it, I literally could not ejaculate—but the promise of release was always taunting me, always teasing to reveal itself if I pushed just a little harder.”

“Huh,” Apple Bloom responded, “you think your dick is cursed?”

Twilight tapped her lips with a finger and hummed. “Hmm, maybe. I really haven’t been able to think straight since this appeared, either,” she said as she gestured at her cock.

“No, I’m pretty sure that’s a normal dick thing,” Apple Bloom said while giggling, “anytime any of my coltfriends got a hard-on, they would just get retarded.”

“Huh… alright,” Twilight said as she looked down at her dick.

“Maybe it just needs a little… outside attention?”

Twilight shook her head. “No… I don’t want to drag you into this. Besides, it seems like my new appendage is magically entrancing you.”

Apple Bloom chuckled. “Nah, that ain’t no magic. I’ve just never seen a dick so big before.” Apple Bloom shook her head. “Alright, let me help you out.”

“I, uh, don’t know if that’s such a good idea—”

“—cram it Twilight. You’ve helped me out so much with my potion-making and improving farm yields. I’m not sure Sweet Apple Acres would be as successful as it is today without what you’ve taught me. So please,” Apple Bloom said, tearing her eyes away from the phallus to look into Twilight’s, “let me help you out, just this once?”

“How old are—”

“I’m twenty-two years old. You went to my birthday party six months ago,” Apple Bloom said flatly.

Twilight blushed. “Ah, heh heh, must be the penis.”

“No, I’m pretty sure that’s just you,” Apple Bloom said as she closed the distance between her and Twilight. “Now, will you let me help you?”

“...alright. But only because you’re one of my favorite students.”

“And you’re my favorite teacher,” Apple Bloom said as she closed her hand around Twilight’s cock.

The effect was instantaneous as lightning shot up Twilight’s spine and directly into her brain. Her knees became weak as she ejaculated an impressive load of semen onto Apple Bloom’s shirt. She moaned and fell backwards, her shapely butt planting itself on the desk as her cock kept on spraying thick, sticky fluid all over Apple Bloom.

“Holy shit, you must have been—” Apple Bloom said before a gob of semen landed in her mouth, the warm, viscous liquid splashing onto her tongue. She was about to spit it out until a nagging in her mind told her not to, so she swallowed it, feeling the load slide down her throat and into her stomach.

She continued to watch Twilight—or more accurately, her cock—spray its payload onto the floor, amazed by the sheer volume of semen. Finally, it subsided, leaving Twilight with a blush and a dumb smile of satisfaction as she panted heavily.

“That was, that was… thank you, Apple Bloom.”

“No problem, Twilight,” Apple Bloom said as she peeled her shirt over her head and threw it onto the floor, revealing her smallish breasts encased by a blue bra. Twilight’s cock twitched again as more clothes slid of Apple Bloom's lean, muscular body, revealing her cutie mark of an apple-shaped beaker half-filled with a green liquid. She stepped out of the jeans, threw them onto her shirt, and looked up at Twilight, her eyebrow arching.

Twilight looked back at her. “What?”

“Usually, that’s,” Apple Bloom said as she pointed at the erect cock between Twilight’s legs that had semen dribbled over it, “supposed to go down after you jizz.”

“Hmm?” Twilight said as she looked down at her penis, which stared right back at her. “Oh. Heh heh. Didn’t know that.”

Apple Bloom glared at Twilight, then buried her face into her hand. “You’re shitting me.” Apple Bloom shook her head, then removed her face from her hand to glare at Twilight some more. “You’re shitting me, right?”

Twilight stared back at Apple Bloom’s bust. “What?”

“You mean to tell me, that in all of your thirty-three years of life, that you’ve never even seen a dick or even done any research on sex?”

Twilight giggled. “The topic never really… interested me. I mean, I accidentally walked in on my brother masturbating once, but I just slammed the door in embarrassment and we never talked about it again.”

“What?” Apple Bloom said as she went over to the door of the study and locked it. “Time to fix that.”

“What’s wrong with not being interested in sex?”

“Everything!” Apple Bloom said as she walked back over to Twilight and grabbed her cock, causing Twilight’s chest to tighten from the sensation. “You feel that?”

Twilight nodded dumbly in response.

“How does it feel?”

“R….really good.”

Apple Bloom grinned slyly. “That’s what you’re missing out on. Allow me to make it feel even better,” she said as she dropped to her knees and kissed the tip.

Twilight felt a wave of pleasure crawl through her from the sensation as she grabbed Apple Bloom’s head and looked into her eyes. “Are you sure this is a good idea? I don’t really want to take advantage of you.”

Apple Bloom sighed. “Please, you already jizzed all over my clothes and a little bit into my mouth—”

“—I did? I’m so sorry—”

“—nah, it’s alright. It actually tasted surprisingly good.”

“Huh, thanks.” Twilight pursed her lips. “Wait, how much semen have you—oh, Celestia!”

Twilight’s question was cut off as Apple Bloom pursed her lips around the head of her cock and flicked her tongue along the underside, sending a thrum of ecstasy through Twilight’s body as she bit her lower lip. Apple Bloom then slid her mouth down Twilight’s cock, the warm wetness sending shivers of excitement through her brain as she gripped Apple Bloom’s mane and closed her eyes, awash with the dirty sensation of sexuality.

“Oh, Celestia, I don’t care how you got so good at this, but keep doing what you’re doing!” said Twilight as her cockhead hit the back of Apple Bloom’s hot mouth. Apple Bloom pulled back, sucking hard and driving Twilight crazy along the way with the feeling of her smooth lips sliding across Twilight's cock. Twilight grabbed Apple Bloom's mane and guided her closer, pushing her cock back into Apple Bloom's mouth as far as it would go.

Apple Bloom soon developed a rhythm, sliding her mouth over Twilight’s penis until it hit the back of her throat, then pulling out until only that head was inside of her mouth and flicking her tongue around it. Twilight tightly shut her eyes, her mind focusing purely on the feeling and all the strange new sensations it brought.

Twilight look down at Apple Bloom. “I had no idea this felt so… good.”

Apple Bloom pulled her mouth off of Twilight’s cock and smiled. “Well, to be fair, you never had a dick—”

Twilight’s vision tinged green as she grasped Apple Bloom’s head in her magic and forced it back down on her cock. “I didn’t tell you to stop sucking.” Apple Bloom nodded as Twilight forced her head up and down her cock, treating her mouth like a sex toy.

Twilight was approaching her limit. She gritted her teeth and forced Apple Bloom’s mouth down her cock and penetrated her throat, Apple Bloom’s gagging finally pushing her over the edge. She grunted as her cock twitched in Apple Bloom’s tight esophagus, spraying jet after jet of hot, sticky semen straight into her stomach as she pulled Apple Bloom’s head down her cock until her lips kissed her crotch.

She held Apple Bloom’s head in place until her phallus was completely drained, then released her head. Apple Bloom quickly pulled her head off of Twilight’s cock and gagged while taking long, ragged breaths as she looked at the ground.

Apple Bloom was staring at the ground and coughing, utterly shocked that Twilight had made her deepthroat her dick. Sure, being treated roughly like that made her kind of wet, but you don’t just do that to a pony without saying something. She looked up at Twilight to say something and froze at what she saw.

Twilight’s corneas were a deep green and purples flames were licking from the corners of her eyes.

Oh shit, thought Apple Bloom as she stood up.

Twilight glared at Apple Bloom. “Did I give you permission to stand up?”

“What?” Apple Bloom blinked. “Twi, your eyes, they’re—”

“—pretty?” Twilight asked as she lifted herself off of the edge of the desk and approached Apple Bloom. “I always thought so myself.” She grabbed Apple Bloom’s face and examined it, her cock pressing into Apple Bloom’s stomach.

“What are you doing?” Apple Bloom asked. This was not Twilight.

“Examining your stock,” Twilight replied as she let go of Apple Bloom’s face. “Hmmm.”

“W-what?”

“Nothing. It’s just that you’re an earth pony. I’ll have to find a better partner.”

Apple Bloom snorted. “Well, thanks, bitch—”

“—don’t call me a bitch, peasant!” Twilight shouted as she grasped Apple Bloom’s neck in her aura and drew her close to her face. “You are standing in the presence of perfection right now.”

Apple Bloom gulped. Something’s really off with Twilight. Maybe I should check out the spell she used to get an idea of what’s going on.

“Hey, Twilight—”

“—Princess Twilight Sparkle, knave.”

Apple Bloom rolled her eyes. “Fine, Princess Twilight Sparkle, do you mind if this knave examines the spell you used on yourself to grow that dick?”

“Why?” Twilight asked as she stared into Apple Bloom’s eyes. “What use would you have for it?”

“Nothing, Princess Twilight Sparkle, I just thought that an examination of the spell under a different set of eyes would help you find your perfect partner.”

Twilight hummed. “An interesting theory, whelp. However, I don’t think—”

Her speech was cut off as Apple Bloom grabbed her cock and stared into her eyes seductively. “I’ll make it worth your while.”

Twilight nodded. “You make an interesting proposition,” she said as she dispelled the magic surrounding Apple Bloom’s neck. “Go and read it, if you can understand it.”

Apple Bloom grit her teeth as she let go of the phallus and walked over to the spell book.

Remember, this isn’t Twilight. Don’t do anything stupid. She sat down at the desk and started flipping through it. It was at this point that she realized she didn’t really have a clue of what the spell was or how to find it effectively.

Apple Bloom looked over her shoulder. “Hey, Twi—”

“—Princess Twilight Sparkle—”

“—yeah, whatever. Could you show me which spell you used on yourself?”

Twilight chuckled. “And I thought you knew how to read magic tomes. Leave it to an earth pony to try and climb above their—”

“—no, I mean to save time. Do you really want to delay finding your perfect partner while I’m reading every spell in this book?”

Twilight nodded as she picked up the book in her aura and flipped to the page with the spell. “You once again make an excellent point, for a mud pony,” she said as she lay the book down open in front of Apple Bloom.

Apple Bloom pinched the bridge of her muzzle. “Thanks, I guess,” she said as she examined the spell that Twilight used on herself. Bonehead.

Her eyes widened as she perused the spell in earnest, then looked back to Twilight’s pulsating cock and gulped.

I really hope I’m reading this right. Either way, this is gonna hurt, she thought as she closed the book, stood up, and turned to face Twilight.

“Princess Twilight, judging by what I read, it says I’m already your perfect partner because you’ve jizzed in my stomach.”

“Is that so?” Twilight said as she turned her head to face Apple Bloom, her green eyes sending a chill down her spine.

“Eeyup,” Apple Bloom said, “it’s kinda like when a dog marks their territory, y’know? So—” Apple Bloom gulped “—go ahead and fuck me.”

Twilight’s ensuing smile was as cold as ice. “You didn’t think I would just fuck you, did you?” Apple Bloom felt Twilight’s magic send her to her knees. “I want you to beg for it.”

Apple Bloom stared cock-eyed at Twilight. “What?”

“You heard me,” Twilight said as she walked over to Apple Bloom and bent over, staring into her eyes. “Either beg for my cock to ravage your innermost depths or I’ll go find some other mare to fornicate with,” she continued as she cradled Apple Bloom’s jaw.

Apple Bloom bit her lip. She weren’t no begging mare, but if this is what she had to do, so be it. She looked up into Twilight’s eyes.

“Please fuck me.”

Twilight snorted. “Try harder.”

“Please fuck me with your giant cock.”

“Better,” Twilight said as she stood up, “but I’m not feeling it.”

Apple Bloom pressed her eyes shut. “Please. I need to feel your monster cock fuck my pussy and turn me inside-out.”

Twilight smirked as her cock pulsed. “Alright, that’ll do.” Apple Bloom felt her body rise off of the ground and slam into the wall as her hooves were planted next to her head. Twilight’s wings extended to their full length as she quickly closed the distance between them, her hands gripping Apple Bloom’s hooves and her phallus teasingly sliding over her folds. Apple Bloom shivered at the familiar sensation.

“Well, aren’t you gonna fuck me?”

“In good time, wench, in good—” Apple Bloom sharply inhaled as she felt Twilight’s cockhead penetrate her pussy.

“Oh, Celestia—”

“—don’t use that whore’s name. If you want to exclaim something, use my name,” Twilight said as she slid another two inches of her pulsating cock into Apple Bloom, sending spasms of pleasure through her body as she wrapped her arms around Twilight’s back, moaned, and nodded demurely.

Twilight steadily rammed her cock in and out of Apple Bloom’s cunt, which gripped her like a warm, wet vise while she flapped her wings to keep afloat. Apple Bloom moaned as Twilight slid another inch inside of her and quickened her pace. Twilight stared into Apple Bloom’s eyes.

“You like?” she asked. Apple Bloom nodded, to which Twilight grabbed her face as she kept up her rhythm. “You will speak when spoken to. Are we clear on this?”

“Yes, Princess Twilight,” Apple Bloom moaned in response as she tightened her grip on Twilight as the cock slid in and out of her pussy.

“Let’s try this again, then,” Twilight said as she let go of Apple Bloom’s face and shoved two more inches in, Apple Bloom whimpering in reaction, “are you enjoying this?”

Apple Bloom nodded. “Yes, Princess Twilight.”

Twilight grinned coldly. “Good.” Her pace quickened as she pistoned in and out of Apple Bloom’s inviting pussy.

Apple Bloom closed her eyes and groaned at the intense pleasure she was experiencing. She weren’t no size queen, but this was amazing. And the hurt Twilight was inflicting on her pussy wasn’t exactly unwelcome. It was a good kind of hurt.

At least, until Twilight slammed her cock into her cervix.

Apple Bloom winced as Twilight picked up the pace and pummeled her cervix in earnest, seemingly trying to penetrate it. Or she was too lost in her own insanity to realize that her cervix was even there.

“Twi—”

“—Princess Twilight,” Twilight said between grunts.

“Whatever. Could you please stop slamming into my cervix?”

Twilight nodded. “As you wish,” she said as she ceased her pounding, which proved to be a big mistake.

Apple Bloom hadn’t accounted for the fact that Twilight’s cock was so wide as to cause intense pain when it wasn’t in motion. The searing pressure on her inner walls was unbearable as Apple Bloom teared up.

“Okay, Princess Twilight, you can keep fucking me.”

Twilight stared at her with those green eyes and cocked her head to the side. “I don’t understand, first you ask me to stop, then you ask me to continue. Why is that?”

“Because it hurts more when you stop then when you go.”

Apple Bloom realized she had made another huge mistake when she felt Twilight’s cock pulse inside of her.

Twilight let out a mirthless giggle. “Then I think I’ll stay right here, then.”

Apple Bloom’s face screwed up in agony as they stood there for a full minute, Twilight’s cock pulsating inside of her cunt and causing immense pain to Apple Bloom. Finally, Apple Bloom could take no more.

“Please, Princess Twilight.”

“Please Princess Twilight what?” Twilight growled, her eyes glinting with madness.

“Please...hammer your cock into my cervix.”

Twilight’s smile curved wickedly. “That’s a good filly. All you had to do was ask.” She then pounded into Apple Bloom’s pussy with supreme vigor, Apple Bloom wincing each time Twilight’s cockhead punched her cervix.

Apple Bloom’s brain was swimming in a mix of pleasure and pain as Twilight kept her rutting up, her head lolling to the side when she caught how far away the floor seemed.

“Uh, Princess Twilight—”

“—don’t you think you’ve said enough?”

“No, Princess Twilight, this is really serious—”

“—I said quiet, foal!” Twilight drew her body away from Apple Bloom and clenched her throat in her hand, cutting off Apple Bloom’s air supply.

Twilight smirked as her cock thrusted in and out of Apple Bloom as she tried to gasp for air. “That’s better. Now you can’t interrupt our glorious coitus with your incessant nagging.” She punctuated the last word with an extra hard thrust, pressing Apple Bloom’s throat more tightly into her clenched hand.

This is actually kind of hot. I wish more stallions had the balls to choke me, Apple Bloom thought as her brain screamed for oxygen, lost in the intense mix of pleasure and pain she was being subjected to at the whim of Twilight’s massive cock.

“Fu-ck—m-e,” Apple Bloom managed to squeak out through Twilight’s hand and the intensity of Twilight’s cock pistoning in and out of her cunt.

Twilight clenched Apple Bloom’s throat more tightly as she gave a vicious smirk while violating the mare. “What was that? I couldn’t hear you over the sound of me choking you.”

“I... sa-id... fu-ck—m-e—Prin-ce…” was the last thing she could muster before she slipped out of consciousness.

Twilight let go of Apple Bloom’s throat as she rutted her lifeless body for a few more seconds, only stopping because she was no fun when she was passed out like this. She looked down to see what Apple Bloom was whining about, only to see they were twelve feet off the floor.

Twilight hummed. As long as we’re up here…

Twilight encased both her and Apple Bloom in her aura as her horn shined brighter, turning her upside down. Her hooves rested on the ceiling as Apple Bloom’s body slid off of her cock, her pussy squelching in response to losing the cock as she crumpled onto the ceiling. Twilight surrounded Apple Bloom in her aura, propped her up onto her knees, and slammed her face into the ceiling.

“Ow!” Apple Bloom said as she jerked back to consciousness, “the fuck was that for!”

“You were asleep. I wanted to wake you up to see how you’d react to this,” Twilight said as she lined her massive member up.

Apple Bloom grunted. “A’course I passed out, you were choking—wait, no, that’s my aAAAAAAAAAAAAAAAAAAAAAAAAA!”

Apple Bloom’s bloodcurdling scream echoed throughout the room as Twilight fully sheathed her monstrous cock inside of her rectum in one swift action, Apple Bloom’s fingertips penetrating the ceiling as she tried to grip onto something, anything, for dear life. Twilight hammered her cock fiercely into Apple Bloom’s asshole, giving a toothy grin as she forced Apple Bloom’s head back by pulling on her mane with her hands.

“Perfect,” Twilight said, feeling the supreme tightness of Apple Bloom’s ass, Apple Bloom’s yelping music to her ears.

Twilight was in ecstasy as she furiously fucked the filly at her mercy, her cock pulsing as it flew in and out of Apple Bloom’s rectum.

Apple Bloom grunted each time Twilight bottomed out in her asshole, her fingers making larger holes in the ceiling as her grip tightened. She looked over her shoulder, Twilight’s heart leaping at the tears streaming down Apple Bloom’s face. “You really like this, dont’cha?” she asked weakly.

Twilight licked her lips as she kept pistoning her cock in and out of her ass. “You have no idea.”

“Well,” Apple Bloom said as she gritted her teeth, “fuck my ass harder.”

“And why would I do that?” Twilight asked as she kept up her pace.

“Because—” Apple Bloom gulped “—I can barely feel your tiny cock fucking me.”

“What?”Twilight roared as she fully impaled Apple Bloom’s asshole and yanked on her hair, causing Apple Bloom to whimper.

“Yeah, I’m a mud pony, remember? My body can take a lot more than this. So fuck my ass harder or I’ll find someone else who can… bonehead.”

The flames licking from Twilight’s eyes danced as she wrapped her aura around Apple Bloom’s waist and positively raped Apple Bloom’s asshole, Apple Bloom’s face freezing in at silent scream as Twilight’s incredibly thick cock ripped in and out of her asshole.

Twilight’s cock felt like lightning in a bottle, awash in ecstasy as she viciously pounded Apple Bloom, her ass gripping Twilight’s cock tightly.

“Do you feel it now?” Twilight roared.

Apple Bloom was unable to say anything due to her jaw being locked open, but shook her head in response. Twilight let go of her mane and slammed her head into the ceiling. “You lying bitch!”

Twilight was close to her limit. The furious pounding was taking a toll on her body as she grunted raggedly, her fucking becoming more erratic. She moved to slow down.

Then Apple Bloom squeezed her ass over her cock.

Twilight’s eyes rolled back into her head as she fell to her hands and knees and screamed, pumping load after load of semen into Apple Bloom’s asshole, the insanity of orgasm clouding her mind as she mindlessly rutted Apple Bloom.

Twilight breathed heavily as the flames shooting from her eyes died down and her penis slowly shriveled into nothing. Her vision became clear once again as she looked around in confusion, a pit of unknown guilt in her stomach.

“Why am I on the ceiling?” she asked.

“Because… you wanted to fuck me here…” Apple Bloom responded as she fell to her side and cradled her abdomen.

Twilight looked down to Apple Bloom, her eyes widening as what she saw. Apple Bloom’s body was slicked in sweat, her eyes pressed shut as her hands covered her abdomen. “Did I… did I do this to you?”

Apple Bloom nodded her head.

Twilight broke out in tears as she collapsed and hugged Apple Bloom. “I’m so sorry! What happened?”

“Well,” Apple Bloom said before giggling weakly, “ya done rutted me raw is what you did. Not sure I’ll ever be able to sit again, but whatever.”

Twilight hugged Apple Bloom even more tightly. “Why did you let me do that to you?”

“Because you went and got yourself possessed by an incubus like a retard and I had to fuck it out of you.”

Twilight arched an eyebrow. “What?”

Apple Bloom pinched her muzzle. “Don’t you read spells before you use them? The text of the spell clearly stated that you’d be possessed by an incubus that would be dispelled the third time you jizzed.”

“Heh heh, thoughtlessly activating spells is kind of how I became a princess,” said Twilight as her cheeks turned crimson.

Apple Bloom chortled. “Point taken,” she said as she nuzzled against Twilight’s body.
