Between orgasming and the present titters, my diaphragm ached. Supposedly the demonheart would enhance my stamina; if so, it certainly didn’t feel like it yet. I might have lost the beat of this orgy altogether, but for the painful and not yet fully sated fuck-hunger, and of course, the Fear Boner.

Every monsterfucker knows it, though they may never experience it in real life. A monster—let’s say for the sake of illustration, a chimera with a bear’s face, faint pink light emanating from beneath cream-colored fur, arms like tree trunks and a long scaly body in lieu of hind legs—picks you up off the ground. Paws the size of your head grip your sides. Ten black claws, each one a spearpoint, dig into you as you’re upended and your legs spread wide. You could be pulled apart like a wishbone, smashed, crushed, bled, chewed to pieces, or your head simply bitten off.

Instead, at the apex of human vulnerability, you’re reminded that for all its perverse whims, the universe likes you. You’ve been marked, not for destruction, but for pleasure. The great white bear smiles, pulls you close to its fuzzy wet snout, and begins to lick out your ass like a honeycomb. Out of reach below you, a bear penis like a seven-inch-long misshapen bicycle horn beckons. The limits, the expectations, the zeitgeist of human sexuality are out the window, and feral fantasies that’d make a pornstar blush are on the table.

“Give me something to suck,” I said aloud. Evidently the room heard me loud and clear, because no sooner had Kae lowered my mouth onto the head of their cock, than I had a half dozen alien looking penises or other extremities flopping around in front of me, and they all got their turn while the bear tonguefucked my tight little ring:

A shoggoth with a knotted, wolf-like penis grabbed my head and humped furiously, although the knot couldn’t get past my teeth and limited the depth of penetration.

An insectoid creature shoved her ovipositor into the back of my mouth; it was stiff and uncomfortable, and I gagged; but it dripped a lubricant that was strangely sweet, and seemed to ease the gag reflex. She shook with pleasure when I ran my tongue around the tip of it.

A demon of the more classic terrestrial design, with tough skin and curved horns, presented me an with insanely long and thin, but otherwise human-like dick. At last, familiar territory, I thought as I pressed back my tongue and let it slide into my throat. Then he started alternating between inserting his cock and the bulbous point of his devil tail, which was a small thing to take, but delighted in wriggling around like a struck bell, making me choke and drool.

I ran my mouth over the fat tip of an octopoid tentacle that was too thick and brightly colored to be Ana’s. It wrapped around my chin and neck as I sucked and slobbered, restricting bloodflow ever so slightly and pushing me deeper into subspace. No sooner had it released me from its grasp, than an enormous orange-and-white striated organ smacked against the side of my face. I knew immediately from the briny smell that it belonged to Prince Asthenar.

The demon prince sighed approvingly as I gave him a nibble and a long swipe of the tongue. “This is lovely,” I said, “but I’ll never get it to fit my holes.”

<You will find a way,> he said. Fortunately, before I could lose too much of my enthusiasm on pondering that, I was turned right-side-up and deposited on my feet on solid ground. My knees wobbled a moment before steadying. As I watched, the prince reared back, lifted Kaesalpinnix mostly off the ground, and inserted the tip of his 18-inch crab-stick into their reptilian cloaca.

I’d been wondering, somewhere in the back of my subspace addled mind, if that hole was usable for fucking. Guess so. Not only that, it was superbly accommodating.

I took a moment to admire the self-sustaining tableau around me. Far from grinding to a halt without someone actively giving it to me, I realized with a start that everyone who had touched me was now at the center of someone else’s attention. They were distributing sexual energies back and forth like a power grid.

Then the moment was up, and Ana, having morphed back into their Baphomet-esque body plan, seized me by the waist.

<ON YOUR KNEES... cutie.>

Shocked by their use of vernacular, I complied. The ground here, or was it floor? had a nice give to it. Still, there was no mistaking the feeling of my body weighing down on my knees as I looked up into their eyes, of which I presently counted five. The rooster’s head growing out of their right armpit had been replaced with the hissing face of a serval, all blunt snout and radar-dish ears. Below that, a large eye, with the distinctive wonky W-shaped pupil of a cuttlefish, blinked in the dead center of their chest, just below the breasts. And below that...

Ana had pushed aside the thick nest of pubes, giving me a clear look at their demon dick. It was a good approximation of an uncut human phallus, and was, as we earthmen say, a chode, built like a fucking coke can. The fear boner intensified.

“Damn, Ana—” but before I could finish my thought, Olkaya’s arms shoved me forward and off balance. Reflexively I reached out and grabbed Ana’s hips with both arms. My lips were right up against the ridged, veiny shaft.

<Yes, we thought you might like that. But listen. If you are to survive the Rite, you must use your gift and grow some body parts.>

These alien monstrosities did seem best suited to each other’s particular hardware. I supposed I could manifest something cavernous to accommodate Asthenar—something like that reptilian cloaca—but picturing myself with it would be tricky. Better to start with something more familiar.

“Alright.” As I kissed and nibbled at Ana’s foreskin, gently tugging it back with one hand, I shut my eyes and tried to picture my free arm as a long, slippery tentacle with a hand-sized club covered in suckers. It worked! Of course, my first instinct was to hold it up to my face, and since I’d been holding tightly onto Ana, this had the effect of yanking at the skin of their ass until the suckers disengaged with little pops.

“Oops, sorry!”

I was figuring out the opening and closing of the suckers when I felt Olkaya’s tendrils slide down my shaft and scrotum, one after the other, and up my ass. This time there was no colon exploration. They just sat there tugging faintly in opposite directions. It was as if...

<Deep breath, human,> she said.

I wrapped my suckers around Ana’s waist for support. A long, skinny, fleshy cock, seemingly the same terrestrial-looking demon as before, slid gently but inexorably up my ass, until it seemed I could fit no more. If I knew me, that was a solid 9 inches. Ana and Olkaya both tightened their grip on me.

The thought of those two restraining me, giving my body over to some anonymous hellion for his use, gave me shivers.

<I have no wish to escape,> I told them, <but I do appreciate the gesture.>

Willing the suckers to flatten themselves out, I bladed the “hand” of my tentacle and began to tease open Ana’s ass with it. This was tricker than they made it look—figuring out use of such an alien transformation is a bit like learning to use your limbs all over again, and I was doing it on the fly, while taking a deep anal dicking. One giant meaty hand grabbed my love handle, and another smacked my ass. It didn’t hurt so much as it shook my entire body.

But, I figured it out. The demonheart gave me a deep well of confidence, and I suppose some intuition about controlling my new parts. And the reward was sweet. I could faintly sense Ana’s surprise at being podded in the butt.

<Very nice, earthman. Now quit stalling and open your mouth.>

Their octopus arm wrapped around my head and over my right shoulder, and shoved hard. With a fat dick like this, I couldn’t avoid some scraping of teeth against flesh. But they paid it no mind. Considering the sort of mouths and mouthparts on display in this crowd, I shouldn’t have been surprised by that.

Ana was just the right size to fill my mouth completely, shoving aside my uvula and tongue and opening up the front of my throat, coming to rest just inside it as my nose pressed against their muscular abs.

<Take me,> I thought at them. <Use me for your pleasure.> My eyes were watery, but my second wind was just beginning, egged on by the Hunger of the black heart.

<Very well. We will indulge your human sentimentality, slut.>

So use me they did. Sometimes more roughly or gently, but for the next half-dozen or so or my orgasms, which I figure for half an hour local time, they never stopped. Seemingly everyone in the assemblage got a turn at my ass, and some of them even gave me a nice tentacular reacharound. I lost the exact count of how many orgasms I’d had after number four. But I do remember clearly the two powerful ones I gave to Ana.

The first snuck up on me, and since they were fully fucking my throat, I only tasted the few stray drops I didn’t swallow. But I felt an echo of its bittersweet pang, like the bite of chiles in xocolatl. The second time it built more slowly; I could feel it in the tension in those gorgeous abs, and the quickening of their pace. I dipped my chin and pulled back slightly, and gave the pod in Ana’s ass a twiddle to help things along.

Paydirt. Ana’s eyebrows just about hit the ceiling, and I heard a deep, almost subsonic rumbling, like the sound of a tiger growling at the far end of a long corridor, Onto my tongue spilled the demonseed, and trying to lap it up provoked even more of it. I realized how apt my analogy had been. It was sweet, salty, nutty, and hot like cayenne. Again, I should have expected something like this, knowing that their nipples tasted like fireball candies. But I was more than a bit subspace-addled.

<Do you have a plan to handle the Prince?>

That’s Ana for you. Businesslike, even while simultaneously getting fucked with an oversized bear penis and trying to wrest back control of my mouth so they could get in a few good post-orgasmic strokes against my tonsils.

In a short time, I’d already come to appreciate my newfound ability of thoughtspeech. Still fighting the urge to gag, I was able to reply: <Yes, but I need Kaesalpinnix! I need to get up close and personal with that cloaca..>

Since their reptilian sex parts were only accessible from the front, Kaesalpinnix opted to lie on their back, and with a well-practiced arching of their serpentine body, exposed themself at an angle suited to well-hung bipeds. A shallow trench of soft pink tissue led into a glistening wet hole, the cloaca proper. My legs were beginning to burn with lactic acid, so I dropped fully to my knees, although it meant entering at a slight angle. My dick slapped rudely against their outer parts.

<How's this?>

<Great,> they said. <You'll hit some resistance from that angle, but it is fine.>

With my two arms, one human, one still octopoid, I grabbed hold of their scaly hips and pushed myself forward. Their hole was smooth and accommodating, but extremely thick-walled, with a viscous lubricant that metered my pace. About six inches in, the space narrowed further, yet it received me readily and deeply, and from Kaesalpinnix I sensed a thrill of pleasure as I gradually buried myself.

<Not to be rude, but which hole is that?>

<The ass, of course. To reach the ovulatory tract you'd need fingers like hers>—here I was sure they meant Olkayabnothep with her tendrils.

I could see why these parts served them so well. Not only could they handle serious girth and depth, the inner muscular wall was reinforced by tough connective tissues that bound it to their spinal column and to their armor-like skin.

I closed my eyes and vividly formed the picture in my head. I could vaguely sense the shift—the yawning cavern that had opened, necessitating a slight rerouting of the large bowel and accompanied by tough plate-like growth at the base of my spine. Also, of course, I felt the Hunger this ambitious and inefficient transformation had incurred.

Ana, momentarily drained but still aroused, came around to inspect the work. Their arms caressed the small of my back, then the pod slipped in and up, feeling out my insides as it went. There was a vague thrill when it reached my asshole.

<Your sensorium is a bit dulled, yes? We thought as much. This will change as you get accustomed to the hardware.>

Without even bothering to retract the pod, they plunged their cum-slicked dick into me. It was strange but definitely pleasurable, and also distinctly gender-euphoric. Something about the subsumption of my front hole and my asshole into one glorious maw felt right. Not only that, I could build proprioception and comprehension much faster like this, with Ana thrusting into my cloaca and me thrusting into Kae’s, the three of us neatly in sync. I knew I’d have to recreate it on a smaller scale for anything less than monster demon dick, but I was getting the hang of that very quickly.

And presently there was, in fact, monster dick available, and the desperate hunger of the black heart turned my thoughts inexorably toward it.

<I'm ready for the main event.>
