A hot night in sweet Apple acres

It was just about sunset as Twilight leafed through the ancient tome the archeologists had sent her. It was in old gryphonic, and she was one of the few scholars in equestria who could read it. It was the last book from a library in the ruins of an old gryphonic city. It was a spell book, which was odd since the gryphons had no innate magic.

She knew she should be getting ready for her date with Pinkie, but the book presented an interesting riddle. Why would the gryphons, a race with no magical abilities, write a book of spells. It just didn't make sense.

She sighed, setting the book aside. Time to get ready for her date. She was determined to be on time. Pinkie never admitted it, but Twilight knew that all the focus she put on her studies recently hurt her girlfriend. She wished there was something she could do to make it up.

Then she realized: why not plan something special for "desert?" She knew how much that girl loved her sex life. Maybe there was something she could do to spice things up. Then it hit her.

One of the spells might help. She quickly went through the book. At last, on a completely innocuous looking page, was the title: "A spell for a more interesting sex life."

"That should do." Twilight thought aloud. After looking over the page a few times, she read the incantation aloud. "Hoc liberum mali spiritus!"

The next moment, Twilight was shocked to discover... Nothing had happened.

Twilight sighed. "Oh well. I guess it was a dud. Better get ready for my date."

Meanwhile, at Sweet Apple Acres

Applejack looked out across the orchard and sighed with contentment. It was beautiful at this time of day. The varied colors of the sunset were gorgeous, reminding her of a certain girl's wild hair.

As she began to think about her crush, her thoughts becoming more and more dirty, she didn't notice the figure approach from behind.

Applejack was startled out of her fantasy by two hands: one over her mouth, another down her pants.

She heard a slutty voice from behind: "My my, you're wet. I wonder who you're thinking of."

She felt a body press up against her, one with a fair bust. The voice came again.

"I suppose I should introduce myself. Once I was Cleona Rashkae, the most powerful enchantress in all Gryphonia. Now I'm a demoness. I need your body, and I'm going to take it. But first,"

She pinched Applejack's clit, making her squeal.

"I think I'll have some fun."

She grabbed Applejack by her hair and dragged her towards the barn. Applejack then did perhaps the most reasonable and natural thing possible. She screamed at the top of her lungs

Cleona laughed."I placed a noise containment shield around me when your foolish alicorn friend freed me. Scream all you want, so long as you're within 10 feet of me, no one can hear."

She threw open the barn door, and chucked Applejack onto a hay bale.

That's when Applejack got her first glimpse of her captor. She was as tall as her brother, with crimson skin and a sizable bust, at least DD, and a forked tongue flicking out of her mouth. Looking down, AJ saw something that made her gasp: a penis.

Already nearly at full erection, it was a foot long and at least an inch and a half in girth. It was pointed, like a gryphon's and complete with scarlet balls, the size of tennis balls.

Then the smell hit her: the smell of pre cum. This time, however, it was different. It made her blood feel hot, and made her arousal even worse.

"Let's get those clothes off of you, my new bitch."

As she reached for AJ's pants, AJ decided to act. Puting her hands against the barn wall, she pulled both legs back and kicked with all her might, knocking her captor on her butt. She then made a run for the door.

Anyone normal would have broken ribs from such a kick. Even Big Mac would have been winded. But Cleona didn't go down so easily. She was up again, quick as lightning, and before AJ could even reach the door, she had her by the hair once more.

"I thought you would simply let me give you one last good fuck before I poses you. I guess not. Oh well. The hard way is just as fun."

She grabbed some rope, and used it to tie AJ up at her wrists and ankles.

"I think I should punish you properly for that foolish little outburst." She sat on a hay bale and bent AJ over her knees pulling her pants and panties down.

"Now repeat after me: bad bitches get spanked."

"Never!"

The sound of a slap echoed off the walls. AJ fought off tears as her ass stung from the blow.

"Let's try that again. Bad bitches get spanked."

"No!"

Another slap. AJ bit her lip.

"Bad bitches get spanked."

"No." AJ was quieter this time.

Another slap. AJ's ass cheek was turning red.

"Bad bitches get spanked."

AJ's voice could be heard, quiet and full of pain. "Bad bitches get spanked."

Another slap. "I can't hear you!"

AJ shouted. "BAD BITCHES GET SPANKED!"

Cleona smiled a wicked smile. "I don't think you mean it." She gave AJ's ass another slap.

AJ broke into tears. She began shouting hysterically: "Bad bitches get spanked!" as blow after blow landed. Finally, after what seemed like hours, Cleona said: "I think you've learned your lesson."

She got up, and threw AJ, still crying, face down on the hay bale, her ass in the air.

Cleona licked her middle finger and stuck it up AJ's asshole. She was stunned by the heat that finger gave off.

"Mmm, nice and tight. Might want some lube, though. And since I don't trust you to lube me,..."

AJ gasped as she felt Cleona stick her tongue up AJ's asshole. She worked it in circles, twisting and turning it. AJ found herself moaning at the sensations.

It was impossibly long, squirming so amazingly. She screamed as she orgasmed, femcum running down her legs

All too soon, she heard a very lewd slurping sound, and it was over. "Now for the fun part."

AJ mustered the little resistance she had left and clenched her asshole closed. She felt something push against it.

She felt a pair of hands grab her behind, their nails digging in to her still sensitive cheeks. "It's too late for that, BITCH!"

With that last word, she thrust with all her might. AJ screamed as the largest cock she had ever seen, far larger than any toy Rainbow had ever used on her, lodged itself halfway up her ass. She continued to clench, despite her sore anus.

Cleona began to pull out. "Good," AJ thought, " maybe she'll leave my ass alone."

Soon, only the last 1/2 inch was left in. But then, Cleona thrust again. This time, she got a little deeper. She began to pull out again.

This went on for some time. Finally, once the count reached 10 inches in, AJ felt a large lump push against her anus. After a moment, she realized it was Cleona's knott.

There was a pause, and Cleona's hands left her ass. For a second, AJ dared to hope that it was over.

Then she felt Cleona's breasts press against her back, and Cleona's hands pulling her up. She then grabbed AJ's shirt.With a quick tug, the buttons popped off, and the shirt hung limply. Her bra proved more resilient, but it, too, was no match for Cleona's superior strength. Cleona then put her hands on her breasts, playing with her nipples. "Ready for my favorite part, bitch?" She whispered in to AJ's ear.

AJ's eyes widened as the knott pushed against her already sore anus. Excruciatingly slowly, it began to enter. Once it reached halfway in, the rest shot in, pushed by her over stretched hole.

"Yeah! Suck me in, bitch!"

Cleona rocked back and forth, wiggling her hips. AJ moaned as the massive cock wiggled too. She had never liked anal before, but this felt different. The cock was radiating warmth, relaxing her muscles. Where it had at first felt like she was going to be ripped apart, she now felt only a wonderful fullness.

She suddenly felt Cleona's nails dig in to her breasts . "Get ready, Bitch! Here I CUM!"

As Cleona screamed that last word, AJ felt a torrent of hot jizz begin to fill her guts. It felt like a fire hose had been shoved up her ass and turned on. And yet, Cleona didn't seem to let up. And it felt so good, like it was warming her from the inside. AJ felt herself getting sleepy. She felt like she should resist, recalling some danger. Hadn't her captor said something about needing her body? Oh well. Certainly Cleona was just as tired as she was. It couldn't hurt to give in to the warmth and fullness, just for a minute or two. She wouldn't fall asleep, just rest her eyes. Yes, just for a few minutes...

Cleona smiled as AJ snored beneath her. It was too easy.

"Good night bitch. When you wake up, you won't be in control."

She pulled out of the sleeping girl with a lewd pop, this followed by a fountain of cum. Cleona's form shimmered for a second, and she put her hand on AJ's forehead.

"Who next? That cute tomboy you were fantasizing about?"

From outside the barn, she heard a masculine voice calling AJ's name.

"I know!" she grinned wickedly, "How about your big brother..."

Big Mac has a REALLY bad night

Big Mac knocked on the barn door. "Sis, are you in there?"

After a moment, there was a reply.

"Yeah."

"Well, I just wanted to remind you that you promised to make a pie for the crusaders, who are coming over later to celebrate Scootaloo's eighteenth birthday."

"Can't granny smith do it?"

"She's visiting aunt orange, remember?"

"Oh, alright! I'll be out in a minute!"

Big Mac sighed. Why did she have to get off in the barn! She had no problems getting fucked by her girlfriend anywhere, or anytime for that matter...

Cleona smiled. The fool fell for her impersonation of his sister, and he was alone! Great! That meant she had that boy all to herself. She loved breaking males. She licked her lips, pulling memories of him from the still unconscious AJ. With a little work, he'd make an excellent servant.

She felt her form waiver. She couldn't hold this body together much longer. She looked at AJ.

"You've got promise, bitch. Now let's fulfill it."

She put her hands on AJ's breasts first. They were good size already, roughly D cup. But that wasn't good enough for Cleona.

Her hand glowed, and AJ grew 2 sizes.

"G cup breasts, check."

She grabbed AJ'S tongue, stretching it to over a foot long.

"Demonic tongue, check."

She reached down to AJ's crotch, touching her clit. It began to grow and change in shape, turning into a 14 inch cock. Two testicles formed beneath it, growing to the size of apples (like the pun?).

"14 inch cock and 2 balls full of Futa cum, check. Well, looks like you complete my wish list."

She put a hand on AJ's forehead. Her form shimmered then vanished.

AJ sat straight up and smiled.

"Time to break a male!"

Farmhouse, 20 minutes later

Big mac sat on his bed and undid the towel around his waist.

"Nothin like a warm shower after a hard day's work!" he said to no one.

"Indeed. It's almost as good as a nice fuck after a hard day's work!"

He looked up to see his door open, and there, blocking his only escape, was his sister, a wild look in her eyes.

He noticed that her breasts were bigger, and he felt an erection coming on. He quickly covered himself in the towel.

She walked up to him. "Aw, come on, every colt has an incest fetish, especially one with two hot sisters. Now show me what kind of heat you're packing."

Frozen in shock, Big Mac watched as she ripped away the towel, revealing his growing erection. As much as he hated to admit it, she was right. He did have a lustful crush on her. He had dreamt of her many times.

"My my, looks like I was right!" she smiled naughtily. "How about we have some fun!"

Big Mac gasped as she grabbed his penis and began to rub it up and down.

"Sis, no! We can't!"

She looked him in the eyes. "Don't fight it, just give in."

He began to feel light headed. He tried to move his arm, to push her away, but the just felt so heavy. He moaned from the sensation of her rubbing him off.

"That's it, relax and enjoy yourself."

She knelt by the bed and unbuttoned her overburdened shirt. Out spilled her breasts (she wasn't wearing a bra), and he realized his earlier observation was right. She had grown.

She knelt, and he moaned as she held her breasts together, slowly descending on to his cock. They were full and soft, and it took all his restraint not to simply begin thrusting up wildly.

She moved up and down his shaft, from tip to base, as he began to moan constantly, his cock steadily leaking pre. It was too much to bear, he couldn't last much longer...

Cleona, judging by the look on his face, knew he was close. She put her mouth around his tip, and sure enough he cried out, her cheeks swelling with cum after a few moments, he stoped, and she swallowed, savoring the taste. He laid back on the bed.

"Ready for round two?"

Big Mac, by now under her spell, gave a classic "eeyup!"

She stood, and took off her pants. Big Mac gasped as her cock popped loose. It was 7 inches, and it was completely soft! He tried to get up, but she got on the bed, straddling his pelvis, his now half erect cock brushing against a pussy hidden by her balls.

"None of that, now, or I'll have to punish you."

He was unable to move as she sat down on his cock, moaning as his cock pushed inside her.

"Oh my, you're a big boy. And handsome, too. Only one change to make."

She began to raise and lower herself, riding his cock. As she did this, she placed her hands on his chest, and he felt a tingly sensation where they touched.

He looked down, and was shocked to see that he was growing breasts! He tried to struggle, but couldn't move!

She laughed. "Already, I control your body, and soon I will have your mind! But first, I decided that you might as well get to impregnate your sister! I can tell you, she's fantasized about it before!"

"Who are you?"

"Cleona Rashkae, the half breed Witch Queen! I shall take over this land, and those who shunned me SHALL PAY!!!"

Big Mac was terrified, and yet, he could feal the oncoming orgasm.

Cleona smiled. "How about I finish this one with a bang!"

She sat down, completely enveloping his cock, except for the last half inch. He felt his flare pressing against her cervix. It pressed harder and harder...

Suddenly, she slipped the last half inch, squealing as his flare hit the back of her womb. This was more than he could stand, and he let loose a torrent of cum into his sister's womb, filling it with his fertile seed.

He felt his mind slipping away into lust, and he tried to fight it. He had to, he couldn't give in. Twilight had to be warned. Maybe she could fix this. Certainly she could stop this monster from doing things to Applebloom. Horrible, perverted things...

Cleona watched as his mind fell to her spell. "You were easier to break than I expected. I didn't even get to use my new cock."

She looked at the clock. "Well, we still have about an hour before those crusaders get here. How about a little more fun?"

She got off of him, his cum leaking out of her pussy, and stood beside the bed.

"Roll over!"

He rolled onto his stomach. She grabbed his ankles and pulled him out to his waist, his dick hanging down limply.

She lifted him up, lining up his ass with her hips. She poked his anus with her cock, testing his tightness.

"Damn! You're too tight. I guess I'll have to figure some thing else out. Roll back over."

He rolled back over, his mouth open. This gave her an idea.

"Spin around so that your head is hanging off the bed."

He did so.

"Good. Now open wide!"

She stuck the flare in his mouth, moaning from the wet warmth.

"Oh my, yes! It's been so long since I throat fucked someone!"

She pushed deeper, watching his throat bulging out. She began thrusting harder, working his mouth like a cock sock.

"You like the taste of your queen's cock, don't you! No need to answer, I can tell by your erection that you do!"

She grabbed his growing dick and wrapped her tongue around it, savoring the taste. A wicked thought occured to her, and she withdrew her tongue, leaving just the tip on his flare. She moved to the opening of his urethra, probing at it. When this earned a moan from him (or it would have if his mouth wasn't being used as a sex toy) she pushed deeper, his cock stretching from the intrusion.

She began fucking his throat faster, enjoying his throat. It couldn't last long though...

She began cumming, filling his stomach with her futa cum.

She took her cock from his throat, and her tongue from his urethra. She began jerking his cock.

"Look up."

He obeyed, just in time to get a face full of his own cum.

"Now go get washed up. We want you to look good for the crusaders. Especially for that damn Unicorn..."

Meanwhile, at the Prench Cafe...

Twilight laughed at Pinkie's joke, happy to spend time with her girlfriend. Unfortunately for her, it wouldn't last long.

Spike ran into the restaurant, dodging angry diners and irate waiters.

"Twilight *gasp* Princess Celestia *gasp* sent this *gasp* for you."

She took the letter from the dragon and opened it.

Twilight, urgent! Do NOT cast a spell from the book you were given. If you have, and are still yourself, come to Canterlot IMMEDIATELY and bring the book! This is a matter of equestria's safety! Trust no one you haven't been with since you cast the spell. I will explain upon your arrival.

Twilight looked up at Pinkie. She had been with her the entire night .

"Up for a trip to Canterlot?"
