The door creaked open, the cold air from inside flowing outward, chilling Nightmare's oversized cock and balls.
"Prisoner," she called in a seductive voice "your Queen has arrived."
A weak voice came from the darkness: "You are not my Queen."
Nightmare smiled. "Even now, captured, alone, about to die, you still defy me. That will make this even more fun."
Her body echoed her thoughts, her futa cock slowly stiffening with anticipation.
She cast a spell, lighting the only lamp in the dim cell. There, on the other side of the room, was what was once her greatest foe.
Her long hair was tangled, her horn cut down to its base. She was totally naked, except for the chains that bound her to the floor, forcing her to remain on her knees.
She looked up. She tried to hide it, but Nightmare could see fear in her eyes. Fear, and no small amount of lust. Even from across the room, she could smell the arousal of her inmate, turned on by the massive cock her captor possessed.
"So, its not enough for you to see me hang, you've got to have your seed dripping between my thighs as it happens."
"Oh, you don't seem to understand." Nightmare said as she crossed the room, her growing erection bobbing as she walked. "You won't be hanged. This is your execution." She put the tip of her cock on Twilight's nose.
Twilight gave her a confused look.
"You'll see. But first, I need you properly sedated. You don't mind, do you?"
"Actually, I do."
Nightmare placed her hand on Twilight's cheek. "Such a strong spirit. What a shame that I must break you tonight so I can show off your head tomorrow. You would have been so much fun to break slowly, over several weeks. The paddles, the whips, the gags and dildos, oh how I love it. Maybe your friend Rainbow Dash will have as much fight. And Fluttershy, oh how I'd love to tear into that bimbo's sweet little ass. But your's will do for now." She gave Twilight's ass a hard swat, turning it red. The lewd sound echoed through the room.
Her horn glowed as she cast a spell, and a table, about waist high, appeared. She then lifted Twilight, unchaining her then binding her arms behind her back, and set her face up on the table. She spread Twilight's legs apart, leaving her already wet pussy exposed.
Nightmare walked up and, instead of immediately plunging in, knelt down and gave her prisoner's pussy a long slow lick, savoring both the taste and her victim's reaction: Twilight shivered, chills running up her spine.
"Yum. Now I know why the pink one likes you so much. You're delicious. If you weren't such a threat, I would turn you into my personal fuck-slave. Oh well. At least I get to enjoy you tonight"
She stood, and lined her cock up with Twilight's pussy. She pressed against her entrance once, but stoped just before she went in. She repeated this several times, enjoying feeling her fuck toy shiver. Finally, she lined up, and thrust hard.
Twilight's eyes went wide. She had never had a cock this massive inside her. She clenched, trying to force the monstrous intrusion out.
"OH YEAH BITCH! CLENCH THAT TIGHT PUSSY! MILK MY COCK!"
Nightmare loved the sensation of Twilight's tight pussy, especially now that it was massaging her cock. It sent tingles throughout her body. She reached down and gave Twilight's ass another firm swat, the sound echoing against the wall.
She began to thrust, slowly at first, but with ever greater intensity as time passed. Twilight repressed a moan.
"You might as well enjoy this, bitch. It's the last fuck you'll ever get!"
Twilight didn't respond.
"Alright, if you refuse to surrender to the pleasure like this, I guess I'm going to have too take a different angle. I think the shock treatment will do."
She pulled out, her cock making a vulgar slurping sound. She lifted Twilight up, hanging her on a ceiling hook by her wrist bindings. The table disappeared.
"What now?"
"You're about to see."
She lined up for Twilight's anus, and gave a good, hard thrust.
Twilight gasped, and her eyes went wide. This was by far the largest thing she had ever taken up that hole, and that was just the tip.
"Now for the shock."
Nightmare lifted her fuck toy, leaving just barely half an inch inside her (and unhooking her). Then she dropped her, impaling her ass. Twilight screamed in pain from the sudden intrusion. She felt the tingling of a levitation spell, and she braced herself for another brutal thrust.
She tried to keep count of them.
Two. Three.
She watched as the huge cock made her stomach bulge.
Four. Five.
The pain was lessening as it streched her guts out.
Six. Seven. Eight.
The pace was picking up now. It was actually starting to feal...good.
Nine. Ten. Eleven.
She let out a moan.
Twelve. Thirteen. Fourteen.
Some small voice in her head cried out: "fight it!," but it was drowned out by the waves of pleasure.
Fifteen. Sixteen. Seventeen.
The pace levelled out. She was moaning like a whore, not caring about defiance now: her world, her very being centered on that cock...
Nightmare felt her orgasm approaching. Without warning, she threw Twilight on to the floor, her rump stuck in the air, ass hole gaping. In a flash, she mounted the open target, using lightning quick thrusts, her balls making a wet slapping sound against Twilight's pussy. She had already broken her subject: this was for her own pleasure.
After a couple minutes of brutal ass rape, Nightmare could hold it in no longer. She slammed as deep as she could into Twilight's ass, her magical balls releasing gallons of cum into her guts. Her belly swelled, quickly making her look heavily pregnant. She coughed, and spat up about a cup of cum onto the floor. She lapped at it lazily, getting cum all over her cheeks.
Nightmare pulled out slowly, her exit being followed by a geyser of cum from Twilight's abused ass, her belly shrinking as it emptied. The sight was making Nightmare hard again.
"And now, your execution."
She lifted the broken girl up with magic, putting her feet on her cock tip.
"Now, just relax sweetie," cooed Nightmare in a soothing tone.
She pushed Twilight's feet into her urethra, moaning at the sensation. Her cock was enchanted so that, instead of feeling pain, she felt sexual pleasure.
"Now, let's take this slowly, so I can enjoy this. Oh, and keep your arms against your side."
Twilight tried to think of a witty remark, but her mind was slow. All she could do was moan at the warm sensation encompassing her up to her ankles.
Nightmare eased Twilight into her urethra. She took Twilight into a passionate kiss, their tongues twirling together.
She didn't break the kiss until Twilight, smiling happily, was in up to her waist.
Something about this was wrong, but Twilight's mind couldn't quite figure it out. She just wanted to melt into the warmth crawling up her skin. It was already up to her bellybutton...
Twilight looked down, and when she saw herself up to her bellybutton down Nightmare's urethra, she snapped out of her trance.
Her sudden struggles only served to please Nightmare more. "Yes, YES! Struggle for me, slave! You can't get free now!"
She placed her hands on Twilight's shoulders, and started pushing her deeper.
Twilight struggled, but to no avail. She slowly went deeper, until she was neck deep. Nightmare paused.
"Well, this was fun, but..." she pulled a knife from thin air, setting it against Twilight's throat. "I'm gonna have to cut this short. Any final words?"
"You will never defeat us. You may have corrupted Rarity and Applejack, and you might kill me, but so long as you rule by corrupting others, there will be those who will defy you."
"Brave words from a doomed girl."
In one swift motion, Nightmare sliced Twilight's throat, spraying blood everywhere...
Twilight screamed as she jumped awake, sitting straight up. She lit her horn, checking herself in the light. Hooves, check. Wings, check. She sighed.
"Thank Celestia, it was all a dream."
Knowing that she probably wouldn't be able to sleep, she got up, her hooves clicking against her bedroom floor. She headed for the kitchen for a much needed cup of warm tea...
Meanwhile, in another world...
Nightmare groaned as she got up. The one down side to the cock vore: her balls were massively swollen with hot, fertile cum. It was making her very horny.
"Damn, Twilight, for such a skinny girl, you make a lot of cum."
She looked down at Twilight's severed head.
"How about we put all that eager sperm to good use."
Of course, if she wanted a proper heir, she would need an alicorn. How lucky she was to already have one.
"How about we pay my dear sister a little visit..."
Author's Note
So, yeah. That just happened. There will be a chapter 2, but I have no clue about when.
Celestia knelt in the sunlight streaming through the window, ignoring her visitor. It was funny, really. It only took a few weeks after her return for Nightmare to realize that daylight was necessary.
She knew full well what the demon that had possessed her sister had come to do, or at least she thought she knew.
"Which of my orifices have you come to invade now? My pussy, my ass, or my mouth?" She asked, not even looking.
Nightmare smirked, ready to catch Celestia off guard.
"I came to bring you a gift."
She rolled Twilight's severed head towards her once sister.
As she looked down, she gasped, tears forming in her eyes.
"Where's the rest of her?" She asked.
Nightmare patted her swollen balls.
Celestia broke into full tears.
Nightmare, pleased by this, spoke. "To answer your earlier question, I've come for your pussy."
Celestia looked up. "You see, I'm so full of spunk," she leaned back, showing off her watermelon sized balls "and it seemed such a shame to waste it on masturbation. Then it struck me: Why not create an heir!"
Celestia blushed. "You want to impregnate me!"
"Yes. It's the only way to be sure my heir is an Alicorn."
Nightmare looked Tia over. Her large bust and wide hips spoke of fertility. Her pussy was already moist, showing that she was turned on by the thought of being forced into bearing her sister's baby, even though she would never admit it. Even Celestia's futa cock was slowly rising, a fact she was trying to hide.
Nightmare, feeling her own erection stiffening, approached her sister from behind, her own cock resting on Tia's back, and reached around. Grasping Celestia's rod with both hands, she began to jerk her sister off.
"Give in sister, you know you want me in you."
"Never!"
"Very well. If you will not give me what I seek, I will take it!"
She stepped backwards, allowing her dick to hang freely, and guided it in with her hands.
"Tight as ever, dear sister."
Celestia gave no answer, save to cross her arms.
As she began to fuck her sister, she resumed jerking her off. It took several minutes, but she finally got her sister at full mast.
She looked down at Twilight's head. "I think I know how to make this a little more interesting..."
She picked up the severed head and looked at it. "You don't mind, do you?"
She opened the mouth and slowly lowered it over Celestia's cock.
"Come on, didn't you ever want that little slut to suck you off? I've seen what she wore around here, and I can tell you: she was trying hard to seduce you. I wonder if she ever knew of your 'endowment'."
With that, she slammed the head down Celestia's shaft, smearing blood on her cock where it exited Twi's throat.
Celestia, despite her reservations, began to moan. She had often gotten off on thinking of jamming her cock down Twilight's throat. She had to admit, the warmth and tightness of her throat was even better than in her fantasies, even though she was dead.
"No, I must resist!" She thought. "If I let her pheromones intoxicate me, I won't be able to stop her from... "
Nightmare increased the intensity of her thrusts, slamming against her sister's cervix.
"Can't let her... Make me cum... Can't... Let... Her ... Break... Me!!!..."
Alas, her resistance was futile.
Celestia cried out, cumming from both her cock and pussy. She sprayed the floor with cum, slicking it.
Nightmare slipped, falling on her back. Celestia stood over her, a triumphant look in her eyes.
In stead of trying to get away, however, she slowly lowered herself on top of Nightmare's cock.
"Let's do this at my pace now. How does that sound."
Nightmare smiled. The corruption was taking hold.
Celestia lowered herself onto Nightmare's mighty girth moaning at the fullness. Sure, this was wrong. It was incest, after all. But it just felt so good, so right.
She picked up the pace, adding a slight rocking motion in her hips. Nightmare moaned. She never knew how good her sister was.
"Ready to fill me up!"
"Yeah!!!"
Celestia dropped down, impaling herself and leaving Nightmare's flare pressing against her cervix.
It was Nightmare's turn to cry out: "I'm cumming!!!"
Celestia let out a long, slow moan as a thick, powerful jet of cum hit the back of her uterus. Her womb began to swell, filling with Nightmare's fertile cum. Celestia's belly ballooned to almost cartoonish proportions. She dismounted and laid back, angling Nightmare's cock to shower her in cum as more flooded out of her vagina.
She passed out.
An hour later
Celestia awoke to a wonderful sensation on her cock.
"What the hay?"
She sat up, and saw Nightmare giving her a sloppy blowjob.
Nightmare savored the taste of blood and cum on her sister's dick. Taking a deep breath, she pushed down, taking it as deep as she could.
Celestia moaned "Yes, my Queen! Take me deep."
Nightmare held it as long as she could. Once she was about to pass out, she lifted back up. She left in just the tip.
She played around with it with her tongue for a few minutes, then she deepthroated again.
She repeated this process for a few minutes, drawing more than a few moans from Celestia.
Finally, she felt Celestia's cock spasm in her throat, and Tia, putting her hands on Nightmare's head, forced her full length down. Nightmare felt her stomach swell with Celestia's cum. Nightmare's lungs were screaming for air by the time Tia let her up. The last streams came up in her mouth, swelling her cheeks and sending cum through her nose.
Nightmare sat back, wiping the cum from under her nose, swallowing what was in her mouth.
Celestia smiled, watching Nightmare lick her fingers.
Nightmare got up. "That was fun."
Celestia nodded. "I don't know why I resisted. That felt good!"
Nightmare smiled. "Let's do this again some time."
Celestia put her hand on her still distended belly. "Do you think the sperm took."
Nightmare kissed her. "If it didn't, we get to do this all again."
Celestia giggled, "that doesn't sound too bad..."
Meanwhile, in a different equestria...
"It was just a dream, Twilight, nothing more." Celestia said, trying to reassure her former student.
"Well, okay."
Twilight looked up at the clock.
"Shoot, I'd better go. I promised to see my parents for lunch!"
"Then go!"
Twilight hurried out of the room. As soon as the door closed, Luna stepped out of the closet and sat next to her sister.
"Did you get a chance to scan her?" asked Celestia.
"Yes."
"And..."
Luna sighed. "I can't be completely certain, but... I think she did travel between worlds in her dreams last night."
"But that would mean that that awful world is... real! But how would this happen?"
"Maybe she's meant to help that world."
"Hopefully, dear sister..."
Author's Note
And so this ends. But I'm thinking about doing a sequel with the remainder of the mane 6. What do you think?
