Quiver

The human got up onto the bed, sitting up on her knees, and Twilight joined her, standing up on her hooves, so that their faces were level. She kissed her concubine deeply and passionately, using one of her wings to massage her familiar neck and her back, especially that one spot that had been bothering her off and on for years now ever since she reracked a weight wrong while doing squats in her friend’s garage gym. Shows her to not use a proper squat rack even one time, huh? Anyway. That spot, which felt very nice, both for the relief it brought and the softness of Twilight’s wingfeathers against it.

She kept her other wing open, but draped to block the sight of her body from her friends as she gently laid the human on her back in the bed, then used her aura to gently lift up the hem of her dress across her upper thighs, all the way up past her waist, glad that the human had adopted the ponies’ cultural practice of not wearing anything underneath dresses.

She used a wing to massage her now-exposed hips on the spots where the human’s cutie marks would have been if she had been a pony. Though there was a mark of sorts now, permanently drawn onto her skin with magic, identical on each side: A circle of brilliant gold, topped with a pink, six-pointed star.

Twilight smiled warmly at her concubine as she looked into her eyes. She removed the wing from in front of her body, to the gasps of her friends.

Sloping up gently from between Twilight’s thighs was the Gift of the Alicorn. A lovely curve of smooth, luscious flesh, of a deep violet considerably darker than that of her coat. On instinct, the human’s mouth watered at the sight of it. An excited frisson worked its way up her spine as the alicorn approached her body with her own, until they met at the crotch.

The base of Twilight’s marecock was now against her concubine’s lower lips, softly, oh so softly, pressing against her clit. Using her still-shoed, steel-shoed hooves, she pinned her concubine’s arms down to the bed, the metal biting gently into the human’s soft biceps, and yes, they were soft, because she’d become lazy about going to the gym even though it wasn’t like she was busy with anything else these days, but anyway. The Alicorn Princess craned her long neck forward to plant a deep kiss on the human’s mouth, driving the back of her head into the mattress. Keeping up this pressure, she began to rock her hips back and forth, sensually dragging the smooth surface of her marecock up and down and across her like a bow gliding across a set of violin strings. With each stroke, she took care to make sure that the swell of her median ring would nudge against her concubine’s clit, and took pleasure in the resulting soft whimpers.

After a bit of slow buildup, Twilight broke this kiss, and her concubine gasped sharply as she began to softly pant and take in air. Still rocking lovingly against her, Twilight gave her the warmest of smiles as her concubine felt her cheeks burning red. She stared into the alicorn’s eyes, falling in love with their brilliant violet for the millionth Celestia-damned time. Time itself seemed to slow as they held each other’s gaze, all dazed smiles. Twilight dragged her next backstroke out until time itself seemed to slow down to a crawl, and while still staring lovingly into her concubine’s eyes, entered her.

Twilight’s concubine lost herself in the sensation of being filled with the flesh of her Sovereign. The crowned head of the crowned head of Equestria, probing deep into her. Then out. Then in. Then out. Then in.

She rocked her hips slightly in time with each stroke, but had to be careful not to rock her hips too much, lest she overstimulate herself. She tried to focus on the tightness of her body against Twilight, tried to imagine how her contours felt to her. She could see that familiar crimson begin to build up on Twilight’s face as the alicorn continued to stroke.

They looked into each other’s eyes with mutual understanding. Though they could not see the faces of their friends, they could imagine their wide eyes, their shocked expressions, their delightful curiosity. And both Twilight and her concubine intended to deliver, both working now to summon what they needed to from within Twilight’s core. The pace of Twilight’s strokes quickened, along with the pace of her breathing, her eyes closing into lovely ovals to better feel the sensations of her concubine’s body. Her concubine then said those words that Twilight loved to hear.

Well, the first part wasn’t the part that Twilight loved to hear, but the rest was.

“Princess Twilight Sparkle-za de Step-on-Me,” the human said between her gasps and pants, packing as much reverence and worship into her airy whisper, which did not require any acting. “Please, use my body as is the divine right of a Sovereign over Her concubine. Till my unfamiliar and hardy soil, just like the adoption of the steel plow allowed for efficient tillage of the tough prairie of the Equestrian Midwest, starting an explosive growth in agricultural yield which allowed the government of the mid-Celestian era to expand its state capacity at a critical juncture in its economic development out of the mercantilist system—”

Twilight had heard enough. With a lustful groan, she pushed in one last plunge before tensing up her body tight and shuddering. Her concubine squeezed her inside of her, feeling the sensation of each throb, the delight of those ropes of warm liquid filling up her insides, coating her walls. Another shiver ran up her, but she kept holding on tight until the last of Twilight’s pumps had exhausted itself.

Unclenching, Twilight’s concubine felt that hard-to-describe but amazing sensation of her Sovereign sliding out of her, coated in a mixture of both their juices, which ran outside of her and onto the bed. Twilight, for her part, collapsed gently onto the soft body of her concubine, nestling the top of her head underneath her chin, her muzzle resting comfortably on her right breast. As she cooed and shuddered, her concubine began to run her fingers through her mane with a smile, unshoeing and squeezing her hoof firmly with her other hand.

At last, the human could look up to see the look on their friends’ faces, gauging their reaction to all they had just learned and seen. As expected, a mixture of surprise and confusion and fascination and lust, in differing proportions. She smiled.

For her part, the alicorn’s eyes were still closed. But Twilight gave one last, satisfied coo, imparting it with the air of finality. An extremely satisfied grin was plastered on her face as if permanently imprinted on it by magic. The magic of friendship. And orgasms.

“You see, girls? This is the kind of thing I’ve been doing up here. The experience that is just so hard to explain, I really couldn’t find a way without showing you! And as you can see”—Twilight let out a satisfied sigh as a late wave of pleasure conveniently washed through her—”all the stress I had up until a few minutes ago is just gone now! And I’m not just trying to demonstrate something here. I wanted to give you all the opportunity to enjoy it yourselves.”

Her friends all looked at each other in confusion. Rainbow Dash spoke up.

“What do you mean, Twilight? Watching you was really hot, sure, but I thought we already agreed to have sex with her?”

At that, Twilight opened her eyes to look at her friends. “Oh, but I’m offering more than just that! I wanted to give you the chance to specifically do what I just did! But you don’t have to do the exact same thing, of course. There are so many ways to use her body! And doing a variety of things would be better anyway for keeping things interesting.”

“Um Twi?“ Applejack diplomatically pointed a hoof at the mess of Twilight’s now-softened cock, still coated and dripping with her own cum. “It’s not like all of us here have one of those things.”

“Applejack!” Twilight laughed. “Who do you think I am? Not only did I spend a decade of my finite and limited young adulthood glued to books studying magic at the postgraduate level, but as the Alicorn Sovereign of Equestria, I am the most powerful magic user on the planet! Of course I could very easily cast a spell to make sure all five of you have what I have. Though it will only be temporary, unless one of you manages to make my concubine come so hard that you ascend into alicornhood!”

Twilight laughed her adorable, nasal little laugh at her own joke

“But, you know, only if you want to, of course.” Twilight chuckled, and lovingly patted her concubine with a wing. “And don’t worry about how she feels. She is really, really into the idea.”

“Yeah, I really, really am,” she admitted. “It’s absolutely crazy, how much I think about this. Like, to the point where I think I have a brain problem about it.”

Twilight beamed. “So, what do you say, girls?”

From them, she received a mixture of silent and voiced assents, curious and excited smiles. She smiled.

Twilight’s horn glowed, and the air crackled as she sent out a powerful magical zap from it. Then, another. Then, another. Then, another. Twilight and her concubine shared a grinning giggle with each other at the sight of her friends looking down at their transformed bodies in awe. The alicorn whispered some very encouraging words in the human’s ear that caused her to blush and tremble. Then, she spoke to her friends.

“So, who wants to go first?”

“Ooh, me!” Pinkie shouted, enthusiastically waving her hoof in the air. “Pick me!”
