The vibrating horn

Trixie was browsing the library in Twilight Sparkle’s castle, when Starlight Glimmer walked in.

“Hey Trixie,” she said. “What are you looking for?”

“Oh, hello, Starlight,” replied Trixie. “I was just looking for some spell books.”

“Oh! So great that you want to learn some new spells! What type of spells were you looking for?”

“Some... Interesting spells, I guess.”

Just then, Trixie noticed a book that was actually called “Some Interesting Spells”.

“Aha!” exclaimed Trixie, taking the book from the shelf. “Perfect!”

““Some Interesting Spells”?” queried Starlight Glimmer. “Oh, I’ve read that. It’s pretty badly written.”

“We shall see.”

Trixie flipped through the book looking for a spell to practice.

“This one looks good,” she said, pointing at one of the spells listed in the book. “A cleaning spell!”

She looked at Starlight Glimmer.

“Starlight,” she said to her. “Be a dear and stand perfectly still.”

“Wait!” called Starlight. “Trixie, no!”

But Trixie had already started casting the spell, and to her surprise, a fountain of water spurt from her horn. Starlight Glimmer was now wet and grumpy. Trixie stared at her, wide-eyed.

“Oops,” she said sheepishly. “I didn’t realise that’s what it did.”

“What I was trying to tell you is that the spells aren’t really well described,” said Starlight. “I tried what was described as a “baking spell” from that book and ended up setting a meal on fire!”

“Well, with a name like “Some Interesting Spells”, there’s got to be some good ones in there.”

“Actually, the name should be an indication of how vague the author of it is.”

Trixie ignored Starlight Glimmer and continued browsing through the book.

“This one doesn’t sound like it could do any harm,” she said pointing at another spell. “It’s called a “pleasure spell”.”

“Let me see,” said Starlight, reading the spell. “Hmm, I suppose so, but just to be safe, I’ll try it out first.”

“Alright,” said Trixie.

Starlight Glimmer cast the spell, and to both ponies surprise, all it did was make her horn vibrate.

“What in Equestria is this?!” she exclaimed before stopping the spell. “What good is a spell like this?”

“Perhaps the great and powerful Trixie should try!” said Trixie, casting the spell. But still, all it did was make her horn vibrate.

“Hmm, perhaps I need to concentrate more,” she said, casting the spell again. But this only made her horn vibrate even more.

“I knew the author of the book was bad,” said Starlight. “But I didn’t think they’d have the nerve to put a spell that doesn’t even work in their book!”

Starlight Glimmer put the book back on the shelf.

“Come on, Trixie,” she said to her. “I’ll teach you some spells myself.”

Starlight walked out of the library, but Trixie stared up at her horn, still vibrating. Suddenly, an idea came into her head, and she stopped her horn vibrating.

“Starlight!” she called to her, running out of the library. “I’ve worked out what the “pleasure spell” is for!”

“Is that so?” asked Starlight Glimmer.

“Indeed! Let’s go to the bedroom and I’ll show you.”

“Um, okay,” said Starlight, confused.

Starlight Glimmer followed Trixie into the bedroom. She had no idea what Trixie thought the spell was for. Trixie closed the door behind her.

“Now,” she said to Starlight. “Lie on your tummy on the bed.”

“Um, alright,” said Starlight doing so, still confused.

“You see,” said Trixie. “I figured out that while the spell is designed to give another pony pleasure, it doesn’t do so directly, but rather gives the caster of the spell the ability to do so.”

“I still don’t follow.”

“I’ll demonstrate on you.”

Trixie cast the pleasure spell making her horn vibrate, then gently touched Starlight Glimmer’s back with it, massaging it.

“Oh, I see,” said Starlight. “That actually does feel good!”

“You’re welcome,” said Trixie.

“I’m actually a little tense lower down my back. Could you work a little lower?”

“Certainly!” said Trixie, moving her horn down Starlight Glimmer’s back until she felt a particularly tense spot.

“Oh yes!” moaned Starlight. “That’s it!”

Trixie continued massaging Starlight Glimmer’s back until she was completely relaxed.

“That will do,” said Starlight.

Trixie stopped vibrating her horn.
“You know,” said Starlight. “It’s interesting that the spell is called a “pleasure spell”. I know the author of the book is extremely vague, but you’d think it would at least be called a “relaxation spell”.”

“Actually, I don’t think that’s its primary use,” said Trixie. “I believe the spell is actually intended to... stimulate mares in a certain way.”

Starlight Glimmer stared at Trixie, shocked.

“You mean...” she started. Trixie nodded confirming what she was about to say.

“Alright,” said Starlight, laying on her back, spreading her legs. “You can try it on me again.”

Trixie blushed.

“I... I didn’t ask!” she exclaimed.

“But you said you wanted to show me what the spell was for!”

“Only how it gives the caster the ability to give another pony pleasure!”

Starlight Glimmer paused for a moment.

“But I want this,” she said.

“If you insist,” said Trixie.

Trixie then climbed onto the bed, casting the spell again and placing her horn gently on Starlight Glimmer’s vulva. Starlight moaned softly. Trixie then slid her horn slowly up and down against Starlight’s vulva, before then penetrating her pussy with it. Starlight moaned louder as Trixie penetrated her pussy in and out with her horn. Trixie then took her horn out of Stalright’s pussy and placed the tip of it onto her clit. Starlight gasped then moaned loudly. The sensation was incredible.

“Shall I experiment with different speeds?” asked Trixie.

“S-sure!” replied Starlight.

Trixie concentrated hard and increased the strength of the pleasure spell making her horn vibrate faster. Starlight moaned even louder. Trixie then concentrated even harder and made her horn vibrate even faster, making Starlight moan even louder.

“Oh, you’re good!” she moaned.

“The great and powerful Trixie isn’t even done yet!” grunted Trixie, as she made her horn vibrate violently fast, making Starlight pant between moans. Trixie then stopped the spell and collapsed on the bed.

“That was amazing!” said Starlight Glimmer. “You sure learn fast.”

“That I do,” said Trixie. “No need to thank me.”

“I think I should! Perhaps I could try that spell on you some time!”

Trixie grinned. “That would be very nice.”
