"What a pleasure to have you here again, Shining Armor." Celestia said, a warm smile on her lips.

The stallion bowed, glad to be in Canterlot again, even if temporarily.

"The pleasure is all mine, Princess." He said, a hint of pride in his voice.

"Oh please Shining, drop the formalities." Celestia waved a hoof, giving the stallion a quick nuzzle. "We both know you're above these dusty traditions."

"It's just a matter of respect Princess." Shining giggled awkwardly. It was the first time Shining had seen Celestia without her usual regalia, he was indeed quite surprised; it's funny how a crown and some golden horseshoes can make such a big difference.

"It's just a casual talk, dear." She chuckled, trying to shake his uneasiness away. "Just old friends chatting. Can you picture that?" She asked, walking past him and whipping his face with her tail playfully. That candy colored galaxy covering his sight for a second.

"Yeah, I guess so." The stallion said, climbing into a fluffy couch and pulling a pillow. He had never been in that room of the castle before, it was near the top of Celestia's tower; ornate windows covered a large part of the walls so the sun could reflect brightly inside, the place was brighter than any other chamber he had seen, but nonetheless it was comfortable and warm. "Cadance said you wanted to have a conversation about... immortality."

"And some other things, yes." Celestia noted, pouring herself some sort of liquor, acting as if that was the most trivial topic in the world "Here." She said, levitating a glass of the beverage towards the stallion. "It is Neightalian Aged Cider. You'll love it - I haven't met anypony in a thousand years who didn't."

Shining accepted, taking a sip from the beautiful chalice. A clean, slightly cutting taste of green apples washed his tongue. It seemed to float as he swallowed. A very peculiar taste indeed.

"Wow. That was..."

"Unexpected?" Celestia chuckled, joining him at the fluffy couch.

"I'd say fantastic, but unexpected fits too." He said, smiling. "What's the big secret behind it?"

"Time." The princess said, as she emptied her glass. "A few hundred years actually. You see Shining, time is capable of turning even the cheapest cider into this. It sharpens the taste, gives the golden color this splendorous brightness; it's almost ethereal."

Shinning just nodded, mesmerized by the cider.

"It is sad to think that the ponies who bottled it never lived long enough to bask in this unique pleasure." She mused about the idea. "It doesn't always needs to be this way."

"What do you mean?" Shining asked, observing the reflection of the chalice on the floor.

"Life, that's it. Ponies got used to the idea of living short lives; it's not like there's something wrong with this, no... But once in the past there were mages, kings and queens who outlived their own kingdoms."

"How come?" Shining cocked his head like a curious dog. "I thought immortality was something one was born with."

Celestia's eyes were lost on a sun-bathed tapestry hanging on the wall. At times she seemed to observe invisible scenes, reminiscences that only her mind has access.

"There's no such thing as 'true' immortality. Although there are many ways that may lead to this seemingly ageless state of being. Most of the techniques have been lost, or are way too difficult to recreate in the present days; hence the rare nature of ageless beings."

"Well, that is surprising, to say at least. I thought you and Princess Luna were the only ones.... Discord aside."

"Oh, no dear. I had the chance to know a few ponies in this planet who have obtained similar effects, some are still around - but they are not very enthusiastic about revealing this nature." Celestia said.

"Why wouldn't they?"

"Let's just say that some techniques used in the past to reach this stage are not widely regarded as ethical. Although none of the ponies I know have subjected themselves to the dark arts, many rulers of the past were associated with vampirism, mainly in the western societies." Celestia cringed at the thought of ancient blood-baths.

"T-that's... Creepy." Shining coyly said.

"It is. Fortunately, that's not performed anymore. At least not that I'm aware of. There are cleanest ways to maintain an ageless spell. That's why you are here, Shining."

"W-what?" He stuttered, caught by surprise.

"After your daughter was born, Cadance has shown interest in learning about these modern spells."

"She wants to become an immortal too?" He asked, taken aback by the news. "She never mentioned this before."

"Not immortal. As far as I know, she's only interested in having a longer lifespan, and this would include you, of course." Celestia reassured him, seeing uncertainty stamped in the stallion's eyes. "This sort of spell, or practice, is more efficient when done by two ponies who share a strong bond. I believe you'd be the best choice for her, wouldn't you?"

"Yeah- I mean.. Of course. I just wasn't expecting this." Shining sighed.

"There's nothing to be afraid of. If you're willing, I'd like to make a demonstration of the spell Cadance will be practicing, naturally, it will work way better between the two of you." An odd grin had formed on Celestia's lips.

"A-alright then, princess. What part of this spell am I responsible for?" He asked.

"None. You are a very powerful unicorn, this is enough to make the spell work. You see, there must be always a receiver and a giver. Both are benefited in the end, but the more powerful the giver is, the stronger the spell. This is something that crystallizes with time, so the process must be repeated once in a while."

Shining looked hesitatingly at the princess.

"You're not going to drink my blood, are you?" He joked, forcing a giggle.

"No... Blood is related to pain, therefore it is not a good magical conductor. That's why the vampires of the past had to kill so many ponies to maintain the same effects. Their thirst eventually reached a non-return point, and most of them died or collapsed. Until a certain princess discovered that pleasure-related fluids were nearly one hundred times more conductive than blood."

The stallion seemed greatly intrigued at that revelation.

"Pleasure-related fluids?" He raised an eyebrow.

"Yes Shining, I'm sure you have fed Cadance with some of it before." She chuckled mischievously. "She already told me about. I wouldn't have called you here for a training session if she hadn't suggested."

It couldn't be what he was thinking. It simply couldn't.

"Training... Alright... At least it's good to know you're not intending to suck my neck, right?" Shining glanced awkwardly at his hooves.

"No silly, just your cock."

Before the stallion could express a shock reaction, Celestia struck him with a spell. There was a flash and an electrifying bang, followed by a lightheaded sensation.

"Woah, what d-did you-" The dazzling light of the room seemed to drip into his eyes. It was the weirdest trip he had experienced since high school. It didn't lasted very long though.

Shining shook his head, looking around for the princess, only to find an oddly recognizable pink-haired mare on her place.

"What in Tartarus is going on?" He asked, finally noticing the cutie mark of the pony. "P-princess Celestia?"

"Call it time travel if you wish." She giggled. "And if you call me 'Princess' again, I swear I'll cut your tongue out." Celestia planted her fore-hooves on his chest, pushing Shining until he was on his back.

Although she was still an alicorn, much had changed in her appearance. The most noticeable abnormality was her mane - it wasn't flowing, sparkling, or emanating any sort of magic - It was just a plain light pink mane.

"You like it?" She asked, looking back at him with a sardonic smile.

"That's so fucking wrong, you know that?" Shining replied, trying to stand, but being instantly pushed down by her hooves again.

"You can complain with your wife later; she's the one who asked me to do this." She stated.

"I don't believe you."

"You don't have to. Just relax." With that, Celestia backed away from him, pushing the stallion against a pillow with her magic, he felt like a rag-doll under the care of a psychopathic filly. "I'm not that bad, am I?"

Aside from her mane, Celestia definitely looked younger; certainly smaller than Luna. She could easily pass as one of Cadance's cousins, if it wasn't for the cutie mark.

"Why the changes?" He struggled to move, but found that his upper body was locked on place.

"Most of ponies see in me a 'motherly' figure." She giggled, shaking her head. "I'm sure you wouldn't feel very comfortable having your dick sucked by your mom."

He opened his mouth to reply but had his current of thought interrupted when Celestia nuzzled his balls.

"F-fuck." He muttered, shocked to see that he already had a half-boner between his legs. For how long was he laying like that?

"Yeah..." She gave him a luscious look, as if expecting a candy bar to grow in front of her. "It works better this way."

A shiver ran up his spine, as Celestia crawled onto the couch again, lying on her belly, her pristine fur almost merging with the textured fabric. She pushed his hind legs apart, exposing his boner.

"Cadance wasn't lying..." She muttered, letting out a chuckle. A hoof moving up to stroke the base of his erect cock. Shining suppressed a grunt, closing his eyes as his cheeks flushed to the color of a red gala apple.

He wriggled in place, feeling the sleek touch of her tongue as it slowly spiraled around the tip of his dick.

"O-over a thousand years of- unf" He gasped, noticing he was again free to move. "...practice, I presume."

"You've seen nothing yet." She giggled, each short breath reflecting on his sensitive skin.

Following a trail of precum that had started to drip, Celestia wrapped her lips around his throbbing member, eliciting a powerful response with every lick she planted. Shining grunted, pushing his front hoofs against the pillows; Cadance was good - she was the princess of love after all - but she was nothing compared to pink-haired Celestia.

Grabbing the base of his shaft with both hooves, the princess turned her head to the side, tasting the fleshy cock as it grew even harder inside her mouth. Now that it was coated in saliva it was easy for her to take more; she looked up at Shining as the tip of his mast prodded against the back of her tongue.

"Yeah... Go- Teach m-me how to be immortal." He said, fighting against the urge to fuck that tight mouth.

Celestia bobbed her head up and down, feeling the ring of his cock bumping against her lips and allowing it to slid swiftly into her mouth. She leaned against shining, holding him tightly, as the bulging head of his cock was pushed into her throat. The princess swallowed, moaning deeply as she suppressed her gag reflex.

That stallion was massive.

She pulled it out to breath, a juicy string of saliva and precum dripping down her chin. Shining placed a hoof on her head, sinking his cock into her mouth again.

"You're not my princess anymore, remember?" He joked, hearing as response only the wet splattering noises of his balls pounding against her muzzle.

His tongue rolled out of his mouth, as waves of pleasure crept up through his entire body. Her muffled moans reverberating on his dick, a drenched spot forming on the fluffy couch underneath their bodies.

"Let's make this magic happen." The stallion said, unaware that his words would become true.

Celestia's horn glowed like a piece of the sun itself, an immobilizing power freezing his limbs in place again. Celestia planted a small kiss on the tip of his cock, he grunted, feeling another spell entering his body through his stallionhood. His back ached as the strange warmth permeated his insides.

"As you wish." She grinned, nuzzling his length tenderly.

Shining gritted his teeth, feeling each electrifying touch multiplied by a hundred, whatever monstrosity Celestia had done to him, it was making his mind implode, his arousal levels reaching a summit he never thought was possible.

Her horn continued to glow as she licked his cock like a lollipop, the glaring sight leaving marks on the back of his eyes.

"Nghhhhh!" He grunted, trying to hold back as his balls involuntarily contracted, jolt after jolt of sexual energy building up on his crotch until a gush of his seed erupted from the tip of his cock.

Celestia engulfed his member again, sucking every drip of cum that leaked out from it. Shining couldn't bear that any longer, that spell was forcing its way out, and he couldn't fight it.

A burning jet of cum exploded from his cock, Celestia was the most pleased with that, as the swallowed the gushing seed of immortality, she pressed her muzzle further until his member was buried deep in her throat. Shining could feel the pressure building up again, as he came another time.

"W-what the fuck-" His breath was erratic as he contorted on the couch, the princess drinking from his cock as if it was a straw, and Shining being a cum milkshake.

She swallowed every shot of his seed, until her mouth couldn't handle anymore and it started to pour down her lips and chin.

Celestia backed away after a sudden spurt of cum landed on her face. She sat on her haunches, contemplating with awe as her milking spell drained the last droplets of Shining's liquor.

Shining himself couldn't do much besides moaning and grunting while his body inevitably shut down from sensory overload.

The world was nothing but a blur when he woke up.

"Oh good, you're alive." Celestia giggled.

Shining blinked, rubbing his eyes with a hoof.

"What?"

The stallion gaped as he looked down to his body and the surroundings. He was drenched, the couch was drenched, even his mind felt drenched.

He stared at Celestia, now back to her normal form. She was as clean and immaculate as ever.

"Well, you asked for the magic to happen." She grinned. "Now... Of course that I may have exaggerated a little bit."

"A little bit?" He jumped from the sticky couch, his legs feeling like jelly. It could as well be described as feeling what a gummy bear feels when it's accidentally dropped on the ground.

"Come on Shining." She chuckled. "You know I wouldn't kill you."

"Not on purpose" He added, frowning.

Celestia rolled her eyes, casting a cleaning spell on his body.

"Cheer up, now you're one hoof closer to achieving agelessness for you and your wife." The princess said. "Besides... It's your turn now."

Shining halted.

"My what?" His pupils shrunk to tiny black dots.

"Well, one must learn how to be both a receiver and a giver... It's only fair." Celestia deserved a medal for that. "Guards! Bring Flash Sentry - Shining is ready for his training."

And that's the story of how Shining Armor never returned to Canterlot for the rest of his immortality.
