A Darkness Within

A Darkness within.

Sunset Simmer laughed maniacally as she held Twilight and her wretched friends beneath her fiery heel. She had regained her full power and demonic form. Her red skin glowing in the perpetual sunset she created using her magic. Her dark draconic wings outstretched in delight, She had won. She watched as her teenage army came marching back in victory, dragging behind them in chains; Celestia. The real Princess Celestia from Equestria and not this worlds pathetic copy. The mirrors magic had done it’s job and turned Celestia human. A perfect beautiful human woman. Unlike Principal Celestia, Princess Celestia hair still flowed without wind. Her breasts were much fuller and she was draped in a stunning, pure white silk dress, Unlike Principle Celestia who wore a tacky brown jacket and purple pants. The teenage zombies threw the former mentor at Sunsets feet. She rose clumsily to her knees unused to two legs.

“Ah, Princess Celestia, you’re looking radiant today.” Sunset gloated, she snapped her fingers and in a dark flash of energy an apple appeared in her hand. She offered it to Celestia. ”Here an apple for teacher.”

To her credit Celestia didn’t say anything, She only looked up at Sunset shimmer with a  disappointed glare. Sunset rolled her eyes and sneered evilly, dropping the apple in front of celestia. She placed her hand under Celestia’s chin and gently lifted forcing her to look her in the eyes. With her free hand she undid the clasp on her fire-print skirt.

“If you don’t want the apple then I’ll be forced to feed you ...THIS!” The demonic Sunset said with a dark and sultry tone. The skirt dropped to reveal a grotesquely huge and terrifying horsecock. Sunset cooed as her dick was exposed to the air causing it to swell a little. The cocks lack of testicals reveled Sunsets glistening pussy beneath the monstrous member. Sunset laughed as Celestias face changed from a look of shock to a look of horrid realization. The sight of the princess on her knees in front her made Sunset feel strong .Powerful. Aroused. Her demonic member began to swell to it’s full size. its flared head was broad and flat with soft spiky bumps along its perimeter, it grew to just over eighteen inches in length and three inches thick. The most intimidating thing however, wasn’t its general size, but the large animalistic knot just above the ring. The knot swelled to an astonishing five inches across and four inches thick.

Sunset Shimmer began to rub her cock over celestia’s stern face. Her pre smeared Celestia’s face and hair. Using her magic she tried to force Celestia to open her mouth, only for Celestia’s mouth to remain valiantly and stubbornly shut.

“Such a strong will you have Princess,”Sunset chuckled teasingly. a surge of black energy swirled around her hands, her eyes turned pitch black. As celestia’s mouth crept open Sunset continued teasing. ”But you know what? It’s not strong enough...”

“No, Sunset! Please don’t do this to her. Take me instead!” Twilight screamed. Interrupting Sunsets revenge, she considered blasting the purple twerp to ashes, but Twilight’s little show did spark an interesting idea. Sunset stepped back from Celestia and turned towards Twilight.

“Excellent idea Twilight,  then she can watch her two favorite students make love, I’m sure she’s dreamed of a moment like this.” Sunset sneered and pointed her cock down in front of Twilights tear stained face.

“ Now suck.” Sunset commanded.

Fresh tears welled up Twilights lavender eyes as she pleaded. “Sunset, I thought we were friends….”

...Friends…

...frie…

Sunset bolted straight up in bed. She clasped her chest, her heart raced and she began breathing heavily. Her purple pajamas were slightly damp from a cold sweat. Staring out the curtainless window she expected to see the town in ruins. Instead she saw the calm, bright, moonlit night.

“Okay, not an eternal sunset. Good. Okay. Everything’s normal.“ Sunset thought as she checked to make sure the world was truly alright.  With that established, she turned her thoughts towards her dream. ”Okay, I’m still me. So, why the hell did I only wake up then, why not when I saw myself as that she-demon or the fact that I had a giant monster cock?”

When the memory of the dream replayed in Sunsets mind; she felt something twitch under her blanket. Looking downwards, the sheet was standing up straight, right between her legs. She threw off the sheet to see what it was and why it felt so good. Sunset gasped when she lifted the sheets it was the same monster cock from her nightmare. Right where her clit should be.

“I must be still dreaming.” She told herself in her mind.

Carefully she reached out to touch her new attachment An electrical pleasure that shot through it as she brushed it with her fingers. With every curious and startled poke as she inspected her new acquisition, caused pre-cum start to form around it’s flared tip. Groaning, Sunset wrapped one hand around as best she could. With her free hand she started playing gently with her pussy lips at the base of her beastly cock. As it crept closer to her mouth, she stroked her cock and brought it closer for inspection.  Her warm, panting breath sent shivers down her length; meeting at her dripping lips. Seeing the glistening pre; she wondered how it would taste.Sunset opened her mouth involuntarily, her tongue lolling out.  Both her pussy and cock ached as her fingers flitted over both organs. She needed to cum..and soon. Drooling, her tongue made it’s way closer to the flared and spiky rimmed head.

Some small part of her screamed that this wasn’t right; that she needed to get help. She paused just before her tongue reached flesh. The voice grew louder and soon it was joined by others. Familiar, caring voices. Regretfully, Sunset pulled herself from the cloudy pleasure.

“I need to...to..” Sunset panted.  She looked back  down at her aching cock pre gushing out, She was so close. It wouldn’t hurt to finish. Another scream from inside forced her to shake her head, clearing it a bit more.

”I need to find Twilight!” Sunset voiced to the empty room.  The air in the room seemed to shudder in response and the darkness seemed to rush in on her.

“ No, we won’t have her interfering with our plans again.” said a voice that filled the small room. The same dark voice that haunted her nightmares. It was her own.

Sunset panicked and tried to jump out of the bed but something held her down. Blue-tinged black energy snapped and crackled around her wrists and legs. Struggling, she watched while a red glow formed itself in the darkness. Sparking with black electricity, the glow formed itself into her old evil form.  Sunset stared in horror at her dark mirror image, right down to the purple jammies, but she also wondered why it wasn’t as well equipped as she was.

“You? But you’re …” Sunset cried.

“Dead?” Her demon-self snapped.” No my dear, I was only put to sleep. Buried deep within the darkest corners of your mind.”

“Ok this is bad, VERY BAD,  but if there is one thing I used to do when I was evil... it was gloat. I have to play along and find out what she’s up to….and how to get out of this mess and get help” Sunset thought to herself before asking.

  “But how?”

“You woke me,” Sunsets evil half started to coo and crawled onto the bed and straddled her waist. Gently she placed a claw over Sunsets lips before she could ask anymore questions. “When you faced the Dazzlings with your little friends. You finally stopped feeling sorry for yourself and unlocked your magic.”

“And….Mmmm, all that power! What a rush!” Her evil self moaned from the memory, stroking Sunsets cheeks as she did. The sultry sound sent Sunset blushing and her cock bumping between the demoness’s shoulder blades. Grinning the doppelganger reached backwards with both hands and started to fondle it, giving Sunset a reverse hand job.  To Sunset it felt as if her other-self’s hands were on fire. The heat burning pleasure into her body with each rise and fall. Every so often sunset would feel a claw scrape down her length, not enough to hurt her, but just enough to let her know who was in control. The pleasure made Sunset quiver and whine and her blush deepened.

“Oh,I see you like thelittle gift I made for us.” The demoness purred.

“What do you want with me and why in the heck did you give me a cock?” Sunset demanded between gasps of growing pleasure. Glaring harshly at the demoness stroking her cock she used every ounce of her will  to pull herself from the brink of orgasm. Even with another girl holding her down and stroking her cock; The determined look on Sunsets face made it seem like she was in control now.

Sneering and rolling her eyes the demon Sunset simply doubled her effort.  Grinning as a squeak escaped her goody-two-shoes plaything, the demon started to grind her hips.  Sunset felt her pajamas moisten where the demon was gyrating, the heavy scent of her arousal threatened to turn her mind blank. Worse, Sunset felt like she was starting to enjoy it. Everytime she was close to cumming the other Sunset would stop her strokes or squeeze her cock harshly. All while staring Sunset down with those piercing blue eyes set in ebony orbs.

“My precious Sunset, I just want us to be one again! With your power and this,” The Demoness squeezed Sunsets cock roughly before continuing. “.. beautiful hunk of meat will help us get revenge ones who humiliated us.”

“No! I won’t let you hurt my friends.”Sunset shouted, struggling against the magical bonds. It was no use, She was held firmly in place.

“Oh honey, when I’m done with you, you’ll be begging me to let you plow all your friends.” The demon Sunset chuckled as she let go of the aching and throbbing cock. She brought her precum soaked hands into view and began licking them; Never breaking eye contact she playfully licked each digit. She even used her fiery tail to tickle Sunsets soaking slit.

“I’ll bet Fluttershy is a real screamer’”Mused Sunsets evil side as she kneaded Sunsets breasts flicking her nipples with a sharp claw.

“I won’t let you get away with this! My friends will stop you.” Sunset gasped.

“Well it’s too damn bad they’re not here. You’re all alone! We don’t need them, we only need each other. Friends are just another crutch, they’ve made you weaker. Without them around you are nothing!” The demoness screamed, her voice dripped with venom and she pinched sunset’s nipples painfully.

 The pain made Sunset scream and jump against her bonds, to her surprise she could stretch out a little farther. There was a murmur in her mind, the same encouraging voices from earlier. Now they were much clearer, she could pick out the voices of her friends and even her own. They were telling her not to give up and that they believe in her. With another surge of strength Sunset fought against her bonds once again. The magical energy struggled against her and with a thunderous crack, the spell was broken. Sunset was free. The demoness watched in shock as Sunset break free. and before she could cast her spell again Sunset was on top of her. Holding her down.

“You’re wrong,” Sunset grinned triumphantly, Her voice rippling with her tormented lust and anger. ”I’m not alone. My friends are with me every step of the way. Even when they’re not here I know they love me like I love them. They haven't made me weaker, they’ve helped me become stronger! I have a home and friends to protect now.”

“W-What are you going to me?” The demoness stammered.

Sunsets grin widened as she slammed her massive cock down between her doppelgangers breasts.The pre soaked tip smearing a white trail against the red skin Sunset shoved her cock deep into her tormentors throat.

“First I’ll shut you the hell up.” Sunset screamed as she shoved her cock deep into her tormentors throat.The demons red tits rubbed the knot while it gagged on the rest of sunsets member. As the rubbery spikes scraped her darksides throat it sent electrical shivers up her spine. Sunset was back on the edge of cumming and with her in control no one was going to stop her this time.

As Sunset came her tormentor tried to moan, but the muffled sound only made Sunset cum harder. With a powerful pulse the first gush of cum barreled down into the demons stomach. watching the evil girls belly start to bulge made Sunset cum even harder. The excess spurting out the sides of her mouth, soaking the blankets in cum.

Satisfied with skullfucking her monsterous side Sunset pulled her cock out slowly. The demons throat was so tight that it didn't seem to want to let her dick go. Sunset sighed as the last inch was freed. Her demon half was in a half choked daze, cum drooling out and dribbling down onto her pajama top.

“Now I’m going to fuck you so hard, you’ll never think about hurting my friends ever again” Sunset sneered and ripped off her opponents pajama bottoms. Placing them down around her ankles. The Demons Pussy was dripping with anticipation.

Sunset rammed her cock in a she hard as she could, only getting to the top of her knot. Even with three fourths of her cock inside, Sunset could see her cock take shape in the demon’s belly. Each rubbery spine found a new ripple or fold inside her doppelgangers pussy making Sunset squeal with delight.The only thing sunset heard from her evil half  was a gargling moan of ecstasy.

 Everytime the knot hit her pussy the demoness had another orgasm every inch of her tight warm pussy was nearly stretched to its limits. Her walls squeezing sunsets cock beautifully trying to milk out Sunsets seed. With one mighty push Sunset shoved the rest of her cock inside. The demon Sunset screamed as multiple orgasms hit her. The feeling of being stretched so much slipped into pure pleasure. Sunset herself came as well as she plunged herself to the hilt. Her previous times cumming were nothing compared to the one  she was having now. every inch of her cock pleasured and her pussy was grinding into the other girls at the same time. Each time her cock pulsed, the  demon Sunsets womb expanded. The knot refusing anything to get out.

Satisfied Sunset fell down on top of her other self panting. to her surprise she heard a soft sobbing beneath her.

“I only wanted us to be together again….”The Demoness sniffled, Tears streaming down her cum plastered face. ”I was lonely.”

Sunset found herself hugging the cum covered monster. she felt sorry for her dark side.

“Maybe we can be one again. I will share my memories with my friends you will learn the magic of friendship. Then my friends will be our friends and I know we’ll never be lonely again” Sunset smiled at her former enemy.

“I-I’d like that” The demoness said and embraced Sunset in a sloppy cum flavored kiss. The two seemed to fade into each other. Making the newly joined Sunset feel whole. The experience left her drained and she drifted off to sleep.

The next morning

Sunset woke up with the warm afternoon sun bathing her in light. She sat up stretching and yawning. She couldn’t wait to see what her and her friends were doing to do today. She felt better than she had ever felt before except she felt an uncomfortable stiffness in her crotch she shuddered as she looked down, recalling the events of last night. There in place of her clit was her huge cock, but instead of evil and tortuous like it was last night. It seemed to take on a gentler look. The Spikes around the tip turned into soft nubs and the knot had a more oblong shape than before. It was still unbelievably large but it seem now to be about giving pleasure than pleasuring itself. Sunset stared in disbelief for a moment before she reached for her magic journal.

She began to write:

Dear Princess Twilight

I need your help, I had an encounter with my evil half last night, I’ll explain more once you get here….But it all started with a very bad dream
