Twilight commanded that I tell her exactly what I wanted and I would do my level best.

My thoughts were fuzzy with lust but I raised my head, took a deep breath, and began as in the canticles…

“My love, my love, my bold one, oft but not oft enough have I known thee, and now I present myself to thee ripe for thy plucking and longing that thou claim my sweetness as thy treasure and prize and justly given due. Seize kindly that which is become yours alone and like dawn’s first light would I fain on the pinnacle thy lofty tower alight my tender secrets, encompassing thy girth, embracing thy length until like the heat and glory of the fully risen daystar shining full upon the blazing minaret reared proud above a dark and slumbering garden will I gently gild thy rigid enormity with the warm moisture of my longing which spills from me like tears of yearning making ready the portal for my lord. Thus when thine triumphant entry is fully gained shalt thou know in sooth my deepest parts, lingering there within my inner bower and departing again hence, nigh unto the very gates of my necessity that thou might enter again victorious in conquest and in this cycle thou wilt further inflame the furnace of my carnal desire and stoke my fierce heat that I shall melt for thee. Hither and thither, from surface to deeps shalt these ritual oscillations delight my sacred flower brimming with honey for thee only, and make way that I receive thy seed like pollen. Like gusts of the hurricane flattening a coastline will our breath be in our exertions, like a galaxy of diamonds shining on midnight velvet shall the sweat of our passion dew our coats before the close of our hidden hour. Let thy mighty thrusting propel the grandeur of thy inlaid scepter into the narrow embrace of my eager vault and so in throbbing apotheosis wilt thou empty the bounty of thy jewels and give forth rivers of pearls until they shall spill upon my loins in streams and fountains. Enter me now divine Twilight, i beg thee, possess my flesh as already thou possesseth my heart.”

I was panting to catch my breath after that speech. I tingled all over like intense magic and my ears were haunted with the echoes as if hundreds of voices had whispered with me, “…as already thou possesseth my heart.”

“Oh buck, that was hot,” Twilight sighed. She leaned forward to kiss my shoulders, the back of my neck, behind my ears. She nuzzled my mane. “I’m sorry for teasing you. That was sooooo sexy I almost came listening to you. I won’t make you wait any more darling, only don’t expect me to last very long my first time making love to my sexy stallion’s sexy pussy. And can you please repeat some of that while I’m actually doing it?”

I put my head back down to watch her entering as best I could. Mirrored floors would be nice…

And then… unlike Twilight’s teleportation skill, there was no popping sound. Only the light flickered and a musical shimmer passed through the air. Even in her wroth, Princess Celestia’s materialization in our chambers was stately.

“Twenty-four hours, said I?” our ruler spoke coldly.

Twilight froze, her fore-hooves on my back, the head of her rigid cock still swaying between my thighs, still so far from my need. I tore my gaze away from the view and raised my head to look at the angry Princess. That was a mistake, eye contact with an entity as powerful as Celestia is not easily broken.

“Clearly I was too generous. Sex magics are forbidden students of the School for Gifted Unicorns, which you technically still are. Get that obscenity out of sight.” She spoke to Twilight but she held my gaze: I could not look away.

Behind me, Twilight shifted on her hind-feet, then tensed.

“Yes—” long pause “—teacher.” The submissive tone in her voice was patently false.

There was a surge of motion behind me; I exhaled loudly, hoarsely, gaze still locked with Celestia’s.

“That is not what I meant.” Celestia, unamused.

Buried balls deep inside me, Twilight had indeed gotten her cock out of sight and I had no complaint about how she did so. And now I knew what it meant to be a mare. Part of my body that had never existed before was full.

“But, tech—” Twilight spoke as she began thrusting deep into me “—nically… it is… out… of… sight… unnnngh… mostly…”

“Have you no shame?”

“I have no shame, have you‽” Twilight pounded my shoulder with her forehoof to accent her shout, she didn’t notice me wince. “I have no shame when I am in my chambers with my chosen one, the somepony special I despaired that I, the so-called Princess of Friendship, would ever know!” Again she punctuated her words with a bruising thump on my shoulder. “The somepony special that I tried my you-damndest to drive away and whose love would not be daunted though I was cruel!” And again. “No, I have no shame at all now, banish us both if you must. Now if you don’t mind, I think something’s going to happen.”

Twilight’s tempo increased, whether from pleasure or anger. I braced my forelegs lest I topple from her rough thrusting. My shoulder hurt, I would definitely be feeling that later. In the mean time, what I was feeling now distracted me quite effectively.

No more words, only our panting breath and moans, the slap of Twilight’s body against my rump. And still Celestia cryptically held my gaze, daring me to blink.

“Celestia’s teats!” Twilight gasped.

“I’m standing right here you rutting foal!” Celestia hoofstomped. The castle shook. Probably the world shook. “Find something else to swear by!”

“How do you control this thing? Something’s… definitely… gonna… happen…” I could guess what was about to happen and I smiled. I wonder if Celestia saw triumph?

But still not a blink.

I could no longer hold myself back; my climax came even while Celestia stared into my naked soul.

The orgasm was unlike the searing flashes of fireworks and visual synesthesia that accompanied my best peaks as a male. This was a wave on a secret ocean, slow, mountainous, complex and powerful. Bigger than us. Bigger than the whole castle, bigger than worlds and deeper than the vasts between them. Rife with strength and mystery, oneness with something ineffable and primal. I could use this power, tap it, draw upon it.

Twilight’s cock grew harder still, throbbed as she moaned her climax only seconds after mine began.

“Nnnnnghhh, Tangent, nnnnnngghhh by Celestia I am yours forever!” she cried.

I wrapped my self, my pleasure, my power around Twilight’s brilliant soul, her orgasm shining like a laser, her love surrounding me like wings and protection, as tightly as my body held her ejaculating cock. Casting, weaving, binding, strands of troth and truth, a scarlet thread, a golden chain I was transcendental and hallucinatory in this moment outside of moments. Time and causality unrolled in both directions and the twin strands were bound up in my spell. Neither Princess sensed what was happening on the astrals but I saw without sight my magic forming, growing, connecting to Twilight’s oath where it hung brightly above us. Streamers of power ran into the dark invisible ocean, waves of fate spreading beyond my ken to unknowable effect. Shadows in the depths connected with my working, sent strange energies crackling into it. On the mundane plane my eyes were wide, my nostrils flared, breath gasping and rough. Still staring into a demigoddess’s eyes, I don’t know what it was I saw there behind the pride and anger. It could have been sorrow or even fear.

I spoke then my beloved’s name, made it a mighty spell.

“Twilight Sparkle, by Celestia my witness —” the holy sun pony flinched then, she began to suspect magic ahoof “ —I pledge myself to thee,” to my ear, my voice had again acquired an echo, as if I no longer spoke alone, “time, and reality, and death will part before us or be ground to dust.”

I still couldn't close my eyes but second sight was crowding in on my vision, the blinding flare of our love-making echoed in nonspace, extending beyond the castle walls.

Celestia’s expression grew sterner, grim even. But she was in control of herself, at least for the moment.

“All right, newlyweds, you may now gasp in shock as I rudely separate you for your own good. Human, we are sending you home now!”, she raised her voice and chanted a spell, in Tartarian or I’m a horned donkey.

The watching part of my mind made careful note: Celestia knows dark magics at least as well as I suspected she must. The first few words sounded like “Rofnar zothnar, razzlefrar….” but even at the best of times I am not enough of a linguist to record magic syllabulary of a tongue I do not speak; with Twilight’s cock exploding inside my pussy, I was distracted enough that I can’t swear if I heard Celestia audibly or if I was picking up aetheric leakage from below my secondary vantage point on the astral plane. Aforementioned mare was so focused on burying her cock in my pussy I misdoubt she noticed Celestia speak at all.

A portal opened black and tearing, an insult to the many fabrics of real, and directly beneath my hooves. For a split second I hung over the void like a cartoon character waiting for gravity to take note of their predicament. Then I slipped off the end of Twilight’s pulsating cock and fell.

“NNNNNNN—” her cry was cut short by the the portal closing with thunderous silence.

I fell into the unknown pit which rapidly resolved into the known and prosaic shadows of my own domicile unit. I tried to stand but I was disoriented and wobbly from the rough landing and interrupted orgasm. Subjective gravity took a sudden turn to the left; I stumbled and fell to the floor.

“Dark portal has side effects,” I noted as the spreading darkness closed towards discontinuity.

And I was a human again.
