Author's Note

This is supposed to be the beginning of a series of one-shot sequels to a fic I may not write for quite some time.

Rarity Does Twilight

Rarity stepped off the train back to Ponyville with determination. She had slept soundly for the whole train ride to recover from the past couple days. However, she had an important mission to which she needed to attend. Spike followed her, helpfully carrying her stuff as he usually did. Rarity's first stop was her boutique to relieve Spike of his self-imposed butler duties. Next, she would go with Spike to the library to talk to Twilight. Her plans were short-circuited when she saw Twilight on the way.

"How was Canterlot?" asked Twilight.

"Simply divine! I got just what I needed," responded Rarity, prompting a subdued snort from Spike.

"What did you buy?"

"I'll explain soon enough. Spike, go on to the library: Twilight and I can easily levitate my things to the boutique."

"As you wish, Miss Rarity!" Spike enthusiastically proclaimed.

"Um, I guess I can go to the boutique with you, I'm not busy now," said a bewildered Twilight.

"Marvellous," responded Rarity as she lifted some of her bags and continued to her house, "Sweetie Bell is with our parents for the week, so I can talk to you. Want to know what I got?" Asked Rarity.

"Yes. I'd also like to know why we're visiting on such short notice. Usually you at least stop by my house for tea first," Twilight, puzzled, responded.

"If you pay attention, they're interlinked. You're a hard-working mare, Twilight, as am I. Sometimes that means you ignore your needs. It's not because you're being self-sacrificing. You simply forget. Put it off too long and things happen."

"What do you mean? You're not making sense."

"I haven't seen you with a stallion or alone with a mare in as long as I can remember. The last time I know you got yourself into that was when you were with Fluttershy. You need somepony, even if just for a night."

Twilight's face turned the colour of Pinkie Pie as the ponies entered Rarity's house.

"I'm not a stallion, why are you taking me to your sex dungeon?" a bewildered Twilight asked as she put down some bags.

"I do not have a sex dungeon," Rarity indignantly replied, "the basement is only good for storing gemstones and I have better things to spend my its on than getting it finished. Come on upstairs, it's a cool evening and I can open the windows."

"You want to mate with me‽? I'm not a stallion!"

"Yes, Twi, you're a mare. I want a relationship with a stallion. Right now, I want relations with you."

Twilight wanted to pretend she was not interested, but her wings gave her body's needs away.

"Now, Twi, you seem to be comfortable with tasting another mare and enjoy horn play. Do you want to penetrate of have my horn in you?"

"I've never had a horn in me before."

"Perfect! I've never put my horn into anypony, so I'll put my horn in you. I'll start by tasting you to get your juices flowing so I know just how much to look forward to whatever dribs down my head, then you can enjoy me to learn the taste of our friendship. Then," Rarity paused for dramatic effect, "we rut!"

Twilight followed Rarity to the upstairs bedroom, warm from the trapped heat of the day, but with a cooling breeze flowing through. Remembering her time with Luna, Twilight sat and spread her legs over the side of the bed. Rarity pounced Twilight and pushed her onto the centre of bed, then gently planted her hooves on Twilight's outstretched wings. Twilight shivered in anticipation as Rarity made her way down, then stopped to give the teats some attention. Twilight wasn't a big fan, and Rarity sensed that and hit the—"Ah!"

Had she known that Luna went down on Twilight, Rarity would now know just what kept Luna there. Instead, Rarity gave the whole area a good, slow lick with her tongue before lying on the bed next to Twilight and motioning for her friend to take her former position. Seeing that Twilight was immobilised with oestrus, Rarity stood up and turned around and planted her muzzle back into Twilight's tasty marehood, prompting Twilight to grab Rarity's rump and bury her face in Rarity's privates.

Twilight got an oddly familiar sensation as she drew close ant even more so on the first lick. They took turns giving slow licks, then Rarity licked her extra good, so Twilight pointed her tongue to get extra deep before lingering on the clit. Her tongue in, she knew where the familiarity was from.

"Ah!" exclaimed Twilight after she lit her head go back on the bed, "you taste almost like Luna!" Twilight was immediately shocked at the sudden over-share.

"So that's what I taste like," Rarity said in attempt to calm Twilight, "now that we're both worked up enough that bad things will happen if we don't finish, stand on the bed and be my horn cozy!"

"You don't think anypony will see us?"

"Nonsense, the lights are off up here and the angle is bad. Let's get to rutting!"

Twilight laid on Rarity's bed, haunches in the air. Rarity's horn glowed with excitement as she got closer and felt the radiant warmth of Twilight's body and the humidity by her plot was enough that even her horn could feel it. Twilight felt a drop of excitement leave her as she shuddered when Rarity's magic aura made contact with her marehood. Soon enough, Rarity's horn parted Twilight's inner labia, beginning to rub into her opening. Twilight was too enamoured to make much noise, but leaned back to take in Rarity's horn faster. Rarity noted that Twilight was lubricated enough for fast action and rammed her head into Twilight's plot, smelling the oddly familiar aroma. The magic aura was like a magnet between Rarity's horn and Twilight's vagina, making sure they didn't disconnect completely until they had finished copulation.

Rarity was shocked at how good having her horn inside another mare felt. She felt all that Twilight felt, but transmitted through her magic instead of her mare parts. Twilight marvelled as every moment was heightened by the flow of magic, this time even stronger since both ponies were unicorns. Both ponies let their magic pool together and flow seamlessly through each other's bodies, stimulating them in ways impossible to describe to a non-unicorn.

Rarity could feel Twilight's fully-extended wings brushing the air while Twilight felt double the sensation of Rarity's horn. Both ponies immensely enjoyed the spiral groove on Rarity's horn, rotating the stimulus as it moved in and out of Twilight's opening. Rarity began to feel as if her own magic was leaking in physical form and dripping off her horn to fill the room with the wonderful scent of a mare in heat. She felt her whole body fill with magic as she came closer to orgasm. Twilight, too felt the build up, her inner lower lips turning into a generator to translate the rotating groove into magic and excitement. Rarity began to feel the magic build pressure now she was full of excitement, her whole body given into casting the strong love spell.

"Twilight dear, if I keep this up, I'm afraid I will lose control of my magic and blow you to smithereens," said Rarity, now worried she would hit a critical bursting point and have a most destructive orgasm in a few seconds.

"That shouldn't happen, especially since I'm an ali—ah!—corn, not just a very powerful un-I-corn now. If it does, oh!, I will have enjoyed my end," stammered Twilight between gasps of pleasure.

Rarity thought it was time to stop thinking and gave a deliberate pull out, losing past of her consciousness as she screwed out of Twilight, then was instinctively shoved back in as her entire being shuddered with relief as all her tension shot out her horn. This blast was enough to overwhelm even Twilight and all the magic in her took the emergency relief valve and shot out her horn and she rewarded Rarity with a blast of mare juices.

Rarity blinked several times to clear her eyes, then saw the scorch mark on the ceiling from Twilight but was too overpowered by the scent now radiating from her face and she slowly withdrew from Twilight to cuddle in somepony's wings on the couch. Laundry could wait until morning.
