Terror in the Pleasure Dome

I had chosen the largest room in the palace for my bedchamber, mainly because it had the most room for bookcases. It was a strange room, dominated by a massive bath, or possibly an indoor swimming pool, with its own multi-pony restroom, and a two-story closet as large as Fluttershy’s house. But I shouldn’t be bragging about my bedroom. I should be bragging about what was in my bedroom. In my bed, actually — a prince from another universe! A very guilty-looking prince, mind you. After hacking the human world mirror to allow free access, travel to other universes became a possibility. The circumstances that led my friends and I to discover Dusk Shine’s universe were quite an adventure, but once we knew where it was, back-and-forth travel was trivial to set up, as was a journal for quick written communication.

“Twilight, we can’t do this. This is so wrong,” said Dusk Shine, hunched up on my massive four-poster bed in a pudgy little ball of woe. I’m not good with feelings, and even I could tell he was having second thoughts about our little project. Which was frustrating.

I rolled my eyes and flicked my tail. “We’re consenting adults. You expressed an interest in this experiment in our personal correspondence. It took us months to find an opportunity to get you over here! Now’s hardly the time to start coming up with moral objections to some perfectly natural and highly scientifically interesting activities!”

I’d be lying if I said I hadn’t expected some problems along these lines. Equestria α and Equestria β (and by the way Dusk’s habit of reversing this notation is highly irritating — we contacted them first, so we get to be α and that’s that) both have very liberal sexual mores, but in spite of the rather improbable parallels in my and Dusk’s life stories, there were still certain differences in our personalities. I’ve done magical scans of my own brain, and found, to my complete lack of surprise, high function in the reasoning portion of brain and minimal functioning in the empathic area of brain — I just don’t understand other ponies’ emotions, so I’ve had to reverse engineer empathy through scientific study, which has proven to be an extremely fruitful line of inquiry. Dusk, however, seems to have a normal empathic capacity. Instead, he has severe social anxiety. Where I had been able to learn the signals I needed to send to get my needs met at an early age, Dusk was simply too skittish to even think about it. Consequently, I was far more sexually experienced than he was. I knew this was going to be a problem going in,[1] but I hadn’t anticipated that he’d try to pull out entirely at the last moment.[2]

Dusk was trembling. “But we’re probably nearly genetically identical. This could be considered incest!”

Oh. That. “Listen, Dusk. There are two reasons I can think of why the incest taboo exists. One is that the unequal power relationships in families can blur the lines of consent. That’s obviously not a problem with us; we’re not related in the conventional sense. The other is that any offspring we had would be at risk for dangerous or disadvantaging recessive genes, which wouldn’t be fair to them, but I’m on so many contraceptive spells that I haven’t gone into heat since I was fourteen. So we’re safe from that, too.[3] So. Any other objections, Doctor?”

He blushed. “Um, no. Not that I can think of.”

“Then kiss me, you overeducated fool.”

He leaned forward awkwardly, eyes closed, mouth open, tongue lolling, and lips sort of rolled out. I sighed. I was going to have to do most of the work here, wasn’t I? I put my hooves on his chest and pressed my lips over his. I took the top one between my teeth and pulled it down, then did the same with the bottom one. Better. Then I ran my tongue across his. Tingling sparks shot through my nerve endings. He let out one of those husky male moans that make my knees weak. His nose kept squashing against mine, though! I sighed, grabbed his head, and tilted his head about fifteen degrees to the side.

“Like that,” I growled.

“Sorry,” he mumbled, “I didn’t know. If you’re not having a good time we can…”

I thumped him in the chest. “Less talking. More kissing.”

His tongue pushed into my mouth, hot and clumsy and seeking. I nipped it slightly, and he shuddered. I pushed his tongue back into his mouth and rubbed my tongue against his big, smooth teeth. He took the hint, biting my tongue in return.

“That’s interesting,” I gasped through the spit strings linking our mouths. “We like some of the same things.”

“That felt really good! I’ve never done it before. Bite my tongue again!” He stuck his tongue out. I laughed, and licked it, wiggling at the texture of his taste buds against mine. Then I bit him as hard as I dared. He yelped.

“Owth! Thath hurt!” he said, rubbing his tongue with a hoof.

I laughed. “We’re silly ponies.”

He laughed, too. “We are. Also we need to kiss more.”

Even in two alicorns of exceptional intelligence and education, mentally and spiritually elevated above the masses of ponykind, the forces of nature can take control. From kissing, we moved to licking and biting one another’s necks. I could see his tumescence bobbing under his bearish belly, and smell the musky scent of his arousal. I could feel myself winking open in readiness, and I saw no reason to delay things. I turned away from him and went down on my front knees, haunches in the air, tail up and to the side, jaw on the mattress. Dusk pressed his nose up against the plush lips of my vulva and inhaled, shuddering at my scent. I expected him to just climb on and start hammering away, but Dusk was a gentlecolt. I felt his magic pressing inside of me, gently exploring and probing. His tongue pressed against my clitoris, and my body shuddered in response. His technique was crude, but his enthusiasm made up for it. I pressed my cheek against the bed and pushed up on my tippy-hooves with my hind legs to give him a better angle.

“Oh… Dusk… Dusk… that feels so good!”

“Am I doing okay?”

“WHY DID YOU STOP LICKING?”

“I’m sorry, I…”

And I grabbed him by the mane with my magic and shoved his nose against my vulva. “Keep licking until I come or I’m sending you home.”

It didn’t take him long. The tension built between my legs, every lick pushing me closer and closer to the point of release. I could hear spit and mare goo dripping on my sheets. I twisted my neck around and opened my eyes a hair so I could see Dusk’s sturdy chest, plump belly, and the long, elegant arch of his cock twitching, drooling, ready, and all because of me! Beautiful, beautiful Princess Twilight, the most important and special princess in all of…

“Oh Faust!” I screamed, a flare of purple light flashing from my horn as my nerve endings sang with pleasure.

“Did I do okay?” asked Dusk.

“Get on top of me!”

“Did you really come? I can do more if you didn’t but I… AHHH!”

I wrapped my magic around his penis and pulled him — maybe a little too roughly — towards me. “Penis! Inside me! Right now!”

He needed to be asked twice, but not more than that. He wrapped his forelegs around my flanks and yanked himself up over my haunches. I let him bounce the flat flare of his glans off my rump cheeks a few times, savoring the thought that I was corrupting such an inexperienced young stallion, then guided him into me. He was a perfect fit. A literally perfect fit, actually. It was like nothing I’d ever felt. He filled my aroused vaginal canal exactly, with none of the pain or discomfort that often accompanies accommodating a large male partner. It was… let me choose my words carefully here… it was delicious.

In implication, as well as activity — how many ponies had this opportunity? How many would take it, if they had it? Fornication with oneself was a violation of all of nature’s laws, both moral and physical, and I relished it.

The bed squeaked and wobbled under us. He moved back and forth inside of me, drawing out past his medial ring, then ramming forward until he almost but not quite brushed my cervix, hitting every nerve ending on the way. His forelegs gripped my haunches, squeezing my rump against his belly. He was shaking. Gasping. I felt wetness on my back near the withers. Was he drooling?

“Oh!” I groaned. “It feels so good! Don’t stop! Please, don’t come yet!”

That was a mistake. I should know from previous experience that “don’t come yet” is the most counterproductive phrase in the Equestrian language. He yelped with pleasure. I considered pinching his vas deferens closed, but I decided to be merciful and let him come. I felt him twitch and pulse inside of me, cum filling my vaginal cavity to overflowing in seconds. I was disappointed he finished so quickly, but it was flattering to think I was such a great lay he couldn’t hold back, and anyhow, I had plenty of experience with overeager stallions, and had prepared for this eventuality.

“Oh! Oh, you’re amazing!” said Dusk.

“I know,” I said, wriggling out from under him and twisting around to kiss him on the cheek. “You were, too!”

He blushed furiously. “I’m sorry I came so soon.”

I floated over one of the half-dozen stamina potions I’d brewed ahead of time from the rack by my bed. “Oh, you’re not half done, bucko. Drink this and get your notebook. We’ve got some empirical data to collect.”

Six hours later, we were thoroughly, utterly spent. My fur was matted and sticky, both in the expected places, and more inconvenient and un-princess-like places, like my face, and all over the underside of my left wing. It had seemed like such a good idea, three potions in, to try alary intercourse, and now I was going to have to send Spike out to find Rainbow Dash in the morning so I could ask her the best way to get semen out of flight feathers (which I was somehow certain she’d know). Almost as bad: after him begging me and begging me for anal sex, I’d finally let him do something human-world Applejack had described to me as “hot dogging”, which she denied having ever done at suspicious length. It was just something she’d heard of. Uh huh. Anyhow, I’d let Dusk slide around behind me and pump between my very deep cheeks to his heart’s content, while I’d clopped away, enjoying the sensation of his cock against me and fantasizing about human AJ’s muscular, freckled ass pearled with cum. It had been great, until he’d emptied a copious load of stallion cum right onto my dock! It’s a huge pain to get cum out of your tail, even with magic!

Anyway, now he was lying on his back on my tangled sheets, hind legs splayed. I was licking his testicles, trying to coax another erection out of him. His balls were the emptiest I’d ever seen — even with all the potions he’d choked down. Still, I couldn’t stop licking them — their dark purple skin was just so silky smooth! Dusk was tugging on his semi-erect penis, which was glistening with animal birthing agent, but he was getting nowhere.

“This isn’t going to work, Twilight. I think… I think I’m done.”

I groaned. “No! It’ll take me hours to make more potions!”

Dusk let his penis flop across the curve of his belly and lifted his notebook with his magic. “Let’s see. I’ve ejaculated sixteen times, and you’ve reported at least twenty-two distinct orgasm events. My penis is, at full arousal, three point six two hooves long and one point zero eight hooves in diameter. Your vaginal canal is more difficult to measure, given the high elasticity of the tissues there, but seems to have approximately the same dimensions. The one time we managed to get most of my… um… stuff into a sample jar, it measured an astonishing four fluid ounces, which you then drank which is the most… uh… scientifically interesting thing I’ve ever seen. Twilight, I think we’re done for the day.”

I sighed. ”I guess Bullddhartha Cowtama was right when he taught that the longings created by indulgence in sensual pleasures could never truly be fulfilled.”

Dusk rolled over on his belly, turned around, and scooted over to rub his soft nose against mine. “I know, right? But it all felt so good! I wish we could have sex just one more time.”

And then I had an idea. One of those ideas. I felt one of my too-wide smiles creep across my face. “You know… as alicorns, and as geniuses, we’re hardly limited by the constraints of our bodies.”

Dusk narrowed his eyes at me. “What are you suggesting?”

“Dusk Shine, how are you at reading minds?”

He looked back and forth, as though there might be someone in the room we hadn’t noticed. “Um… I have never tried, because that would be highly unethical and also illegal.” He was almost at bad as lying as Applejack.

“But if you did know how, and if I knew how too, we might be able to link our minds. We could do literally anything we can imagine, for as long as we wanted to. I mean, we’d have to set a timer on it, so we remember to disconnect before my friends come looking for us and we have some very embarrassing explaining to do that would probably involve Celestia and Solaris lecturing us on proper inter-dimensional diplomatic decorum. But even if we just went ’til dawn, we’d have days of subjective time to play!” It was foolproof. Nothing could go wrong.

Dusk frowned. “I don’t know, Twilight. I’m getting that feeling I sometimes get. You know the one where you think things that are difficult and dangerous for other ponies will be trivial for you, and that you’re so smart that nothing you try could ever possibly go wrong?”

“Yes. That one. Hubris. I get that all the time.”

“Yeah,” he said, “I’m definitely feeling hubris right now. We shouldn’t do this, huh?”

“Nope.” I said.

“But we’re going to anyway, aren’t we?”

“Yup. So should we just touch horns, or what?”

“Yeah, let’s touch horns.”

So we did. And the bottom fell out of reality.
