Menage a trois

It was a quiet, yet peaceful day in Equestria. The ponies were happily trotting around Ponyville, being the joyous equines that they are. In Canterlot, Princess Celestia was writing a letter to her faithful student. Twilight had wrote her a letter about this mysterious pony trotting around mysteriously in Ponyville, then to Canterlot. Her letter reads:

Dear Princess Celestia,

I've met a mysterious elder pony, with a dark robe telling me of this spell going to be cast on Canterlot. He never mentioned his name though. I asked him if was good, and he said "Yes, a VERY good spell. It'll make the most important ponies of Canterlot fall into a deep sense of love." I felt happy that this pony, mysterious-looking or not, trying to make Equestria a happier land. What do you think of this Princess?

Sincerely your student,
Twilight Sparkle

Princess Celestia smiled after reading Twilight's letter. She decided to write back, speaking as she wrote her reply.
"My faithful student Twilight Sparkle, I --"
Just then, the doors swung open. Two of the Royal Guardponies entered the Princess' room, showing their usual faces.

"Princess Celestia. Somepony has requested your presence."
She turned around and smiled. "Bring him in please."

A pony with a dark robe and cyan eyes slowly trotted inside. Was he the mysterious somepony Twilight mentioned?

"May I help you?" asked Celestia, looking down at him.

He was almost Big Macintosh's size, but he was an elder pony. He spoke in a wise, yet elder sounding voice.

"Princess Celestia. May I perform a powerful spell for you?" Celestia looked unsure as of what to think of this elder pony. But she showed respect to him nevertheless.

"Is this spell of your's powerful as you say it is? Is it good too?"

"But of course Princess!"

the elder spoke with a smile.

"Twilight Sparkle mentioned you in her letter to me. Are you this mysterious pony?" the goddess of the sun added, sitting down.
The elder pony chuckled with a smirk. "Mysterious pony. Haha. Most call me that. But yes, I am. My name is Makon."

The Princess smiled, always looking forward to meet a new pony's face, young or old.

"Pleased to meet you Makon." Celestia smiled warmly at him.

Makon stood up on his hooves. "May I ask a favor, Celestia?"

"Of course. What is it?"

Makon's horn starting glowing brightly. The guards were suspicious as to what he up to. They both unsheathed their swords with their magic. Makon quickly turned around.

"Sheathe your swords, for I am not threatening your fair Princess!"

Celestia gestured her guards with her hoof to disarm themselves.

"I'm sure Makon means no harm to me."

The guards did as their Princess commanded, sheathing their swords. His horn still glowing brightly, Makon offered his hoof to the Princess. Celestia held Makon's elderly hoof and Makon began humming, making his horn glow brighter for the duration of his humming. A short moment later, his magic from his horn emitted a bright white heart on the tip of his horn. Celestia stared surprised at his magic. Makon finally released his love-filled magic inside the goddess' heart. She felt a bit woozy from the spell's effect. But she quickly recovered, shaking her head.

"W-what was that Makon??"

"T'was my spell that has been handed down from my family for generations."

He smiled and released his hoof from her's.

"A powerful love spell that takes your truest desire from your heart to your mind. I assure you, it's nothing bad."

Celestia nodded in agreement.

"Okay Makon. I'm holding you to that." she smiled once again, with a short giggle in her voice, battering her eyes at him. It looks like the spell is taking it's effect! Makon could see it in her royal eyes.

"Thank you again for your time, Princess. May we meet again."

The powerful, happy elder smiled and trotted out of the royal bedroom. The guards had no idea what to think, except that he was weird.

"You're welcome Makon. You stud of an elder you..."

She gasped, realizing what she just said. She blushed lightly and headed back inside her room, feeling the powerful spell taking effect inside her body.

Hours have passed. It was now nighttime. Princess Celestia had been in her room for what seemed like ages. She was lying on her royal bed, her horn glowing brightly. An aurora of lust was clouding throughout her mind. She peered downwards towards her flank, seeing that she was getting rather moist there. She felt there, gasping loudly, that the effects of the lust-filled spell made her mare vagina so much more sensitive to the touch.

"Oh goodness...! I-I'm so... so sensitive to this... but why?".

But the royal, and now horny-as-hell Princess started to rub and masturbate herself, gasping for air as she hooved herself nice and deep inside her flank.

"Aaahhh... ahhhh..!! Oh yes! mmmmh!"

Her moans and pleasurable words echoed throughout the castle halls. The guards, pretending not to hear her, heard it anyway. She was leaking and squirting pre-cum like mad, beads of sweat trickled down her pleasured body. A white, sticky mess covered her bed covers, some of it dripping on the floor. She started to scream in euphoria. After trying to resist the spell's power over her, she couldn't, and Celestia screamed one final time, squirting her contained orgasm all over her bedroom floor!

"Ohhh.... Oh sweet pony feathers! That was... so wonderful!~"

She heavily sighed, tired, but satisfied of her climax. Thinking to herself, she spoke her thought quietly to herself. "What if I had somepony to share this lust with? Mmmm.. Perhaps my guards will." She shook her head. "No. Maybe not. Perhaps somepony else... or maybe...?? N-no! Not that." She got rid of the thought, resting her head nicely on her pillow. falling asleep deeply.

The very next morning, after raising the sun, Celestia was trotting down the hallways of her castle, remembering that one thought she had on her mind the other night.

"No, I don't want my guardsmen to know of my activities. But, they DO serve me well. Protecting Canterlot and I. But what Twilight said in her letter. "It'll make the most important ponies of Canterlot fall into a deep sense of love." Did Makon mean my sister Luna too? Or my niece Cadence?"

She trotted off to see her niece, wondering if she and Luna were enchanted with Makon's spell.

This is the end for Celestia's side of the story. Read more on Luna and Cadence's side of the story, of how Makon got to them.
