Rainbow Dash's Fun Talent [Request]

Rainbow Dash slammed her thick, throbbing cock into Twilight's pussy as hard as she could, over and over, as the former princess stared blankly at the wall in front of her. Twilight's body was used to Rarity's cock, which, while certainly massive, was feeble in comparison to Rainbow's girthy shaft. If she could still feel, she would experience a cocktail of pain, fear, and pleasure, as her holes were expanded to match the size of the new object being inserted.

Dash stayed here for hours, fucking Twilight again and again. For some reason, tearing down a high and mighty alicorn that had always eluded her monster cock was the most satisfying thing she had done all day - and many things were in contention for that. But as she blew her final load of semen into the purple princess, she could think of one thing that might just top it.

Rarity hummed to herself, content with her dresswork for the night. The pouring rain outside, paired with Sweetie Belle's lack of bothering her due to her music box toy, had lent themselves to a rather peaceful and methodical night. The chaotic thunder and lightning were certainly frightening to some ponies, but to Rarity, it was like a beautiful symphony of emotions all clustered together in a few moments of nature's glory.

"Hello Rarity," spoke Applejack's voice.

Rarity jumped in surprise, her cock erecting, at Applejack's voice, which had seemingly come from nowhere. She blinked, and looked around in silence for a moment, the rain and thunder the only audible sounds. Did...she really just hear that?

"Hello Rarity," spoke Pinkie's voice. Thunder, Lightning.

"Sweetie BELLE!" cried out Rarity. "Is this some kind of joke?"

Suddenly, four closets in the room opened their doors to reveal Applejack, Fluttershy, Pinkie, and Twilight, all in the room at once, surrounding Rarity. Her cock continued to tense up.

"It's no joke," spoke Fluttershy.

"This is for real," spoke Twilight.

"RARITY!!! HELP!!!!!!!!!" shrieked Sweetie Belle from the other room. Rarity, in sensory overload and panic, cried out, trying to shove past Applejack, who was solid as a rock.

In her room, Sweetie Belle was having her mind taken over by Rainbow Dash. She sobbed and pleaded, her poor mind unable to even fathom this idea of mind control.

"RAINBOW DASH, NO!" she squeaked, her voice breaking, before finally slopping over to the ground. Rainbow Dash laughed maniacally as Applebloom and a newly converted Scootaloo emerged from the shadows to greet their friend.

"You guys fetch me Celestia," joked Rainbow Dash. "I'll have cookies when you get back."

"Okay, Rainbow Dash," the three of them said in unison.

Dash made her way down the stairs casually to Rarity's room, where she was still surrounded by the husks of their former friends.

"Rainbow DASH! What have you done with my sister?" she cried.

"Same as I did with all of them. Warped their minds a bit....now the only thing they do is what I tell 'em."

Rarity, speechless, began to tear up.

"And I suppose that is what shall happen to me, too?" she spoke quietly. Dash chuckled.

"Not necessarily," she said. "You see, Rarity, I've always hated you."

"Y...You have?" blubbered Rarity. She legitimately had no idea.

"Uh, DUH? YES? You were the only other futa-mare besides me! It was like you were always hogging MY attention!"

"D...Dashie, I swear, I-"

"And you would always talk DOWN about me to other ponies!"

That part WAS true, Rarity lamented. Dash was just so...immature, and ungreatful of her massive cock, and...

"I wanna see you suffer," spoke Rainbow Dash coldly, cutting off Rarity's thought process.

"D...Do you mean to torture me....?" sobbed Rarity.

"Yes...but probably not how you're thinking," chuckled Rainbow Dash. "You see, I know how important your reputation is..."

Rarity now began to cry outright. She knew where this was going.

Just a few minutes later, under Rainbow Dash's direction, with the threat of total mind antihalation looming over her head, Rarity had started a "magic livestream" - a screen was being broadcast above Canterlot, high in the sky for all to see, of her room at this very moment. Rarity was now dressed in a ridiculous costume - a skirt far too short to even cover her ass, a flower around her face, and a binky in her mouth. Crying, she made her way in front of the viewport.

"I am Rarity," she blubbered through tears, "and I am a big, big baby...and I...have stupid, smelly penis, and..."

"No!" whispered Dash, from offscreen, totally killing the dramatic atmosphere. "It's stupid, UGLY, smelly penis!"

"R..Right," spoke Rarity, correcting herself. "Stupid...ugly...smelly...penis....and I do not deserve it. Rainbow Dash is..."

Rarity squinted through her tears, trying to decipher the nonsense that Dash had written on the massive cue cards in front of her. It was poorly written in both terms of handwriting and terms of prose. This would be quite comical if her freedom of life wasn't on the line.

"Rainbow Dash is...the extra most bestest pony, and has a way bigger dick, and also f...fucked your mom last night, and your dog, at the same time."

Her tone began to drift into a more baritone apathy as she continued, Rainbow Dash laughing her ass off offscreen.

"She fucked them at the same time, 'cause she fucked them every night for the last...seven years, that now, their holes are so big, that one cock can fit in both of them, even Rainbow Dash's...big, uh, p..p...p...penis...."

The stress of it all finally caught up to poor Rarity. She suddenly bawled on camera, stomping in protest in her embarrassing, ridiculous outfit.

"Rainbow Dash, please, please let me go!!!!" she sobbed. "PLEASE! I can't STAND to be humiliated like this, I, I...."

Dash sighed. She had had enough. She blinked at Rarity, who suddenly shrieked in utter horror as she realized her mind was being taken over.

"NO!!!! NO, NO, PLEASE!!!! ANYTHING BUT THIS!!!!" she sobbed, stumbling around in her ridiculous outfit. Hundreds of ponies in Canterlot bore witness to the sad display of Rarity completely embarrassing herself and then having her mind taken over. Dash laughed as Rarity shrieked her last before glazing over and staring at her new master, awaiting direction.

Dash now made her appearance on the stream, confidently addressing the viewers.

"Hey Everypony! You know me. I mean, of course you do, haha. You've all written me so many letters! And man, it sure feels great to get all that attention."

Applejack, Fluttershy, Pinkie and Twilight slowly joined Rarity and Dash on the stream.

"But you know...it just got...so boring!" continued Dash. "So when I found out that I had gained the power to control ponies with my mind....welll...I started with my friends! But now I realize..."

Her cock throbbed.

"...I just think its fuckin' hot to do to anypony!"

In Canterlot, waves of ponies cried out in terror, starting to flee for their lives.

"So, yeah, you're all next. Eventually. For now, just watch me have sex with my friends, I guess. Nothing you can do to stop me," sighed Rainbow Dash. Her friends closed in on her, and she embraced the pleasure.

She rammed her cock up Rarity's ass, finally getting to fuck the annoying, prissy bitch and get revenge for all that attention that was rightfully hers. Fluttershy and Pinkie, with the biggest asses, rubbed their hindquarters all over Dash and up and down her hooves, giving her all kinds of sensations. Applejack, the ugliest and most useless of the bunch in Dash's opinion, tended to Rarity's cock, lest it remain serviced. Twilight herself did the honors of kissing and massaging Dash during the sex, in full view of the stream - anypony left watching was treated to watching the beloved Princess of Friendship mindlessly suck and kiss away at the ruthless now-leader of the pony race.

They fucked for hours on that stream, only stopping because of the exceptionally long day Dash had been through. Busy work, mind controlling and enslaving all your friends.
