You, a very tall, human dressed in a fancy suit of plate mail armour were kneeled before Princess Celestia, who sat upon her golden throne within the castle of Canterlot.

You stood 8 feet tall, which made you twice the height of an average pony. Your armour was an alabaster white in colour just like Celestia’s coat. Its most defining feature was the sun representing Celestia’s cutie mark situated in the centre of the breastplate. Along with a round, templar helmet over your head. The armour was perfectly fitted around your massive muscles, showcasing them in breathtaking detail.

Princess Celestia herself was a huge alicorn. A mighty shire horse sized steed, if not even greater. However, you knew full well that Celestia was actually much larger. This was only her lesser form.

“What is thy bidding, my fat big sexy love?” you asked in a deep Darth Vader-like voice.

“There is a great disturbance in the Friendship.” came Princess Celestia’s soft, angelic voice.

“I have felt it.”

“The bearers of the Elements of Harmony have a new enemy. Their virginity.”

“.... wait… what?” you asked in confusion with your normal voice.

“Yes. They need a strong, handsome gentlestallion like you to rid them of their virginity once and for all. For too long, I have waited for them to find love. You must make sweet love to each and every one of them with your massive penis. The size and power of your mighty penis will vastly increase the power of the alicornation process. Their bodies and rumps will grow much larger than normal by you making love to them.”

“How do you know they have not lost their virginity?”

“Because they are not alicorns. Anyone who wielded the Elements of Harmony will become an alicorn if they lose their virginity. This has not happened yet, thus they are still virgins.”

You nodded. “Understood. I may need to ask you some questions. I do have some concerns about this quest.”

“Ask away.”

“Will they be able to handle my cock? You have magically enhanced me far beyond a normal human. You specifically made my penis very large and strong so it can pound your ass hard to kingdom come just the way you like it. I fear even if I'm gentle with these ponies that my penis will destroy them.”

“Don’t worry, your penis automatically casts powerful healing spells. However, I'd still advise you to be gentle with them.”

“Yes, of course. Any advice on how to seduce them?”

“Your mission is simple. Luna has informed me they dream about you in a romantic way. So all you really need to do is flex your massive muscles and whip out your massive cock basically.”

“Good. An easy mission.”

“Good luck, my faithful knight. Be chivalrous to them. Treat them with love and respect.” she said while her horn glowing with blinding light.

With her magic, she opened a golden oval-shaped portal behind you. You stood up and pounded your chest in a salute. Then without a word, you turned to walk into the portal.

You came out the other side to find yourself standing before Twilight Sparkle, Applejack, Rainbow Dash, Rarity, Fluttershy, and Pinkie Pie all conveniently sat at the foot of a huge, pink love heart shaped bed. The room was dimly lit with scented candles. Upon the walls of said room there were many pictures of yourself doing manly poses.

“Yay! Anony is finally here!” shouted Pinkie, immediately lunging at you. With lightning-like reflexes you grabbed the over excited mare, and took her into a gentle hug.

You lay your right, armoured hand upon Pinkie’s plump rump upon her cutie mark. Your cold, steel fingers dug deeply into the soft fat of her thick backside. You placed your other hand upon her lower back.

Pinkie affectionately nuzzled your armoured shoulders, humming happily.

Twilight stepped forward and gave you a sheepish smile. “Sorry about that. Pinkie Pie is just really happy to see you.” The shadow of your massive body loomed over the small mare as she stood at your feet. It’s the other way around when you are with Celestia.

“It’s fine, ma'am. I feel like quickly escalating things myself." you pulled your right hand away from Pinkie’s rump. Your hand upon her back held her safely in place.

With your hand now free, you proceeded to snap your fingers with a loud click. Once you had snapped your fingers you immediately placed your hand back upon Pinkie’s rump.

Your armour vanished to reveal your masculine body. You were nothing short of being literally a reincarnation of He-Man. Your body was shaped as if it was a stone sculpture.

Between your legs lay your currently flaccid cock, which stood about 20 inches long at least and about 6 inches thick. Your balls were heavy and meaty, about the size of soccer balls.

The mares stared at you in awe, a strong musk filled the room at the mares from all around you began to leak fluid out of their marehoods in excitement. Pinkie Pie was quivering in your arms, her body shaking uncontrollably. Your hand became damp with her leaking vagina.

Twilight plopped down on to her rump before you. She began to grind her hoof between her legs, and moaned in bliss, all the while she looked up at your masculine body.

You stepped over Twilight, and made your way over the bed and sat yourself down at the foot of the bed.

Rarity and Fluttershy flanked your right, while Rainbow Dash and Applejack lay on your left. Twilight made her way over to sit down between your muscular legs. Pinkie Pie held in your arms began to affectionately nuzzle your neck.

Your cock slowly began to rise to attention, gaining inch after inch by each passing second, and expanding in girth at the same time. The mares simply looked on in awe as your penis grew larger and larger before them.

Eventually it reached its apex height and thickness. Your cock was so long it came to bump against Pinkie’s rump above. Your hard shaft depressed her soft flesh deeply as it pushed into her plush rear. In terms of thickness, it was like you had grown a third leg basically, somewhat like a traffic cone.

You stood primed and ready to make sweet love to these ponies with your ridiculously large cock.
