While Twilight dozed after our heavy conversation, I slipped from bed and crept to the spare room where I discretely kept my personal collection of magical tomes.

It was time to test a spell that had failed me many times. My most recent attempt, that failure had felt different. That time I had grabbed threads of deeper power and pushed. I failed, but moments later, on the very edge of too late, Twilight had appeared.

Taking a deep breath, I faced the wall and spread my arms. There was a glimmer of magic and I could see the interior of my hidden workroom in Ponyville Castle.

Ah-ha!

There was nothing wrong with my magic all along – Princess Celestia’s barrier had blocked me, just as it once blocked Twilight. Now that Twilight had broached the barrier with her incredible ability, I, too, was no longer hindered. And I had confirmed my theory that the portal between universes to Equestria was fundamentally different than the same-universe magic I used to reach Gallop: I was not subject to the inexplicable three day cooldown that would have stopped me from re-opening the Gallop portal so soon.

Without delay I pushed abook laden cart through the portal. I had loaded it with my most esoteric volumes, copies of lore from the earliest days of human and prehuman magic. A very specialized collection, indeed, utterly unique. Over the years, I had abused library access to transcribe my own complete set of the most arcane volumes known to man. Hand copying the ancient texts like a mad medieval monk in a monastery I had reproduced every word onto sheets of nigh indestructible cellulose. My tubular metal pens held immalleable ink able to permanently record dark lore on such eternal pages. Protective metal covers latched tight and ensured that my distinctive printing would remain legible for unknowable hundreds of centuries. They would wait for me in Equestria where nopony could find them.

As the portal closed I chuckled. All these years, pounding my head on this spell, blaming myself without realizing that I had been trying in vain to overpower Celestia’s own magic. It was no wonder I had failed where Twilight had needed to exert her full strength to succeed.

Quietly I returned to bed, seeking my drowsy husband’s cock.

—

When I slid between the sheets I found that Twilight had rolled onto her back – perfect for my next move. Stealthily I straddled her legs below the knees and lowered my face to her cock. Without waking my princess, I slurped her limp dick into my mouth and began sucking as it grew. Whether fellatio or irrumatio, taking a hard member in the mouth is hot. But taking it soft, and feeling it swell to its full glory inside my mouth, was another level of satisfaction. I didn’t just find her all hard and erect, I got her hard. As her cock sprang to full wakefulness, so did she emerge from her slumber.

“Tanna, what are you doing?”

I wasn’t going to let go of her dick to answer – surely she’d figure out on her own soon.

“What time is it?”

This time I paused from assaulting her dick head with the back of my throat to come up for air, and to answer.

“It is time to fuck my mouth, my beloved, mouthfucking, Princess.”

I returned my mouth to her cock as if it were my salvation. Really it might be. I needed to get off this planet, and if my theory were correct—

Fuck me and fuck my theory, lust swept over me and her cock in my mouth was the universe, was the driving purpose of creation and I needed her come, the fire of her sex. I didn’t need to breath, I seemed to steal oxygen directly from her bloodstream as she panted for both of us. I missed any warning her body tried to give me and suddenly my mouth was awash with the luxurious heat of her orgasm. Refusing to relinquish my hold, I swallowed every drop without ceasing to lavish my attention on her twitching member. I had a vague memory that the head would be super sensitive after climax, but I would not be displaced as she writhed beneath me. Only as her cock returned to the soft state where I had found it did I raise my head and draw a gasping breath before collapsing.

The fire down below had beckoned throughout the act, but I never found the attention to spare to pleasure myself. Now I lay aquiver at her side, needing but too worn to do anything about it.

At least there was certain sense of accomplishment, having taken her full cycle from limp, to climax, and back again, almost uninterrupted in fellation.

“What was that about?” she asked, bemused and limp.

“I could be wrong, so this is just a suggestion, but last time you were on Terra, it seemed to help replenish your magic every time we had sex. I just want to try to get home to Equestria as soon as we can.”

“Hmmm.” Twilight’s attention faded as she introspected her internal magic energy level. “You could be right.”

“So I’ll just do that any time you can get it up until we can get out of here.”

“Don’t be crazy– I don’t want you to do it like that all the time. You could hurt yourself, taking me that deep in your throat so vigorously.”

“I’m sorry princess. I just want you to fuck me, to use me, until you have the power to take us home.”

“What about you?”

“Hmm?”

“What about your pleasure?”

“Optional. At least until we reach Equestria.”

“Nope, I am not going to allow myself to get into the habit of treating you like a sex object. I’m fine with your suggestion. Let’s make love often, let’s rut like overstimulated weasels, lets even make like real humans and fuck. It’s even okay if it’s one sided, one way or the other, sometimes. But I need your pleasure as much as my own. Besides, maybe it’s not my orgasm that boosts my power, maybe it’s yours. So we should have lots of those, too! Alright, sweetie?”

“Well,” I said, rocking my hips to present myself to her, “if you insist.”

Her dick might be limp as a noodle after the the oral attentions it had received, but I knew her fingers and tongue were very capable.

—

I was dozing again, worn out first from the stress of telling Twilight about my sins of the blade, and further from casting, and yet further from our following interactions. Even half asleep, I felt her move before she put her hand on my shoulder.

“Wake up, Tanna,” she said. “I need to talk to you.”

“What is it, dear? What do you want to talk about?”

This was obviously not going to be a restful night.

“Foals,” she said. She seemed to have reached some decision while I slept.

“Oh, I already told your mother that I draw the line at eight, though in I suppose I could entertain your arguments for more. Do you want me to bear them, or will you? Are you going to put another baby in me, my Prince?”

I patted my belly, and gazed longingly at Twilight.

“You met my mother? When? No, that doesn’t matter. You aren’t fertile right now are you?”

“No,” I said, confused.

She had sounded alarmed. Why?

“But I could be in short order. I have enough Terrestrienne magic for that.”

“I’m sure mom loved your answer, but there’s something I’ve never told her.”

I sat up now, blinking the sleep from my eyes.

“I visited a seer, a few years ago. Not Fluttershy manifesting the goddess this time, this was a forbidden consultation.I traveled weeks and weeks to see it.” Twilight shuddered at some memory. “I can’t repeat most of what it told me. But one thing I have to tell you: my second foal will destroy Equestria. Which is why we must stop at only one.”

“Oh, Twi!” I threw my arms around her and wept.

“When I asked who the father would be, it laughed like a mad thing. Are you terribly disappointed?”

“I wanted to have a big family with you, our very own herd of foals. But not at the expense of everything you and I stand for.”

“That's a good girl.” She was patting my back. “Equestria over all. At least if I only get to have one, Gloam is an incredible filly.”

“Yes! I knew you would love her. And I promise you,” I said eagerly through my tears, “she’s such a hoofful of trouble that you’ll feel like we have a whole castle full of foals. Chaos ninja cookie-assassin foals!”

“I’m not sure if that is supposed to reassure me?”

“Maybe?” I closed my eyes, focused inward for the space of three breaths. “There. So long as I am the female member of Team Us, I won’t ovulate. How come you asked Gloam if she wanted to be a big sister?”

“I should not have said that, I was wrong to do so. In my defense, I had just had a bit of a surprise and I was not at my most rational. I’m really glad she didn’t leap at the idea.”

So was I. I had spent years hoping to bear more of Twilight’s foals. The loss of that possibility was an ache in my womb. But any threat to Equestria was anathema before which my maternal yearnings could not stand.

“Comfort me.”

I still hadn’t released Twilight from my embrace when I made the demand.

“Er, how?”

The movement of my hips answered her question.

Twilight started to release me. Presumably to move her hands to my breasts or groin, but, “Nuh– uh,” I mumbled. “Hold me.”

We were still side by side in bed, awkwardly twisted to embrace.

I flopped onto my back, pulling her after to sprawl across me. With a wiggle she was lined up with me; we lay diagonally across the bed without any concern for the linens.

Still holding her tight, I demanded her kiss before she could ask me what next. Her body figured out what next on its own. Her cock was still recovering from an epic blowjob, but I could feel it stiffening despite its recent success. When I thought she was hard enough to penetrate me, I rotated my pelvis, inviting her to do so. Her first attempt was too low and I pulled away as best I could from beneath her. Anal was not what I wanted this time. A second attempt, she missed my pussy and plowed her dick between my labia, almost ramming my clit. After avoiding what could have been a deal breaking party foul, she worked her way back down my slit, gentle penile feints searching for an opening. Too high. Too high. Just right.

Nope; a little to the side.

Twilight rocked her body to adjust the angle of her dangle and pushed again.

Any concern I harbored that demanding action without foreplay might have been a tactical blunder was obviated as she slid inside me. This was my purpose in the universe, to be a receptacle for Twilight Sparkle’s throbbing erection. As smooth as watered silk it pushed all the way home and I sighed, open mouthed, into her kiss.

Lip to lip, arms wrapt around each other, we continued our wordless fucking. Thought contracted down to the thrusts of her hips and the heat of our union.

Nine times nine strokes, the far eastern sex guide advises. I wasn’t in any condition to count, but it had to be at least a hundred and then I was coming again. Through the entire length of my orgasm, Twilight thrust remorselessly, no change to her rhythm. At some point my hands had migrated down her body – she was going to have a fine set of fingertip sized bruises on her ass cheeks and I was still pulling her into me with each thrust, wondering if she was close yet. It was like she was going to fuck me forever, and I found myself starting to arouse again. There was no way I’d be ready to come again so soon, but I was gasping as I drew towards another impossible peak.

Still surrounding me with her embrace, Twilight’s pace grew faster in response to my fevered breath. Harder, better, faster, stronger she pounded me and even though I knew I was not going to climax in time before she’d be done, I was okay with that, eager only for my princess, my husband, to reach his own pinnacle of pleasure. I could swear I felt her dick swell inside me and I knew she was on the verge of ejaculation.

I gave my lewdest moan and felt her entire body react.

Just when she was going to fill my hungry lust with the sperm I yearned for, she pulled slightly too far back on the out-stroke and her cock popped out of my pussy. Past the point of inevitability, there was no recovery and she thrust onward, grinding herself against me. Her twitching erection schlicked up and down my steaming cleft and the unexpected clitoral stimulation of her cock shaft rubbing across pushed me to climax just as her hot liquid love leapt forth.

Harder and harder still I pulled on her ass, holding our bodies together, sandwiching sweet seed between us.

I must have blacked out from pleasure. After some interval of discontinuity I returned to something like awareness. I was still beneath my lover, surrounded by her arms as she lay upon me.

“Oh, buck, that was hot, Tanna.”

Twilight seemed to’ve noticed that I wasn’t out any more.

“Thank you for fucking me, my lord Princess. I am somewhat comforted.”

“Should we, uh, go get cleaned up?”

“No, we should stay like this ‘till it dries between us like glue.”
