This story was written as Day 15 of Kinktober 2019 for Greycait. Today's theme was Tentacles, and the story contains rough sex between consenting adult males, one of whom may or may not be inhabited by a tentacle-laden symbiont. :3

The Lust Within

Damascus looked at his arm, flexing his fingers and testing the responsiveness of his various joints, beaming as everything reacted that much more swiftly and seamlessly thanks to the new wiring he'd installed. Pushing himself back from the desk at which he'd been working for most of the day, the lion leaned back in his swivel chair, stretched with a groan of satisfaction, and glanced over to where both his shirt and the synthetic cover which made his cybernetic limb seem almost indistinguishable from the rest of his black fur. Before he could roll himself over and slip on that covering though, never mind his shirt too, the door to his workshop burst open as a panting, trembling figure lurched through it. The lion's eyes widened, and for just a moment he tensed his limb, ready to unleash the hidden blade lodged within it to defend himself. As soon as he recognised the man still stumbling towards him though, he let down his guard.

"Skal? Uh, everything okay, buddy?"

Even as Damascus addressed his friend though, he knew what was happening. He could see it etched across every last bit of the deer's strained, desperate face, and of course in the substantial tent in the stag's trousers, his shirt rippling and stretching too as though something was writhing and fighting to break free through the fabric. Sure enough, just seconds later Skal fell to his knees, and even as he began to crawl towards Damascus, he let loose a bellowing cry as his clothes were torn apart by what lay beneath them, now revealing themselves in all their glory.

"I... oohh god, Damascus, I... I tried to hold back. To stay at home a-and deal with it myself this time. But... they wouldn't let me. Tina, t-they... oh god. They needed someone, Damascus. They m-made me need... o-oh god, I'm so fucking horny. I need you. I need your ass. Your body. I... ah! Aahhhhhgodfuck! Please!"

Two thick, glistening tentacles erupted through the sides of Skal's shirt, while another pair erupted from another just as large and forcefully ripped hole in the seat of the deer's trousers. A glazed, frenzied intensity crossed the deer's eyes in that moment, and his expression twisted from one of conflict and embarrassment to one of pure lust as the symbiont dwelling within him took hold, and he scrambled his way the rest of the way across the workshop floor before lunging at the chair upon which the shirtless, blushing lion was still seated.

With another bellowing cry from the stag and a mewling exclamation from Damascus, the two men tumbled to the floor in a heap as the lion was dragged from his chair. Damascus tried to tell Skal that it was okay, that he understood and that he was willing to help; to let both the deer and his symbiotic companion know that he didn't need to take what the lion would give freely, but it was too late. Before he could even begin to speak those thoughts aloud Damascus watched as another hole was ripped forcibly open in the fabric of Skal's trousers, and from within not a tentacle but a huge, weaving prehensile cock burst out. A second later Skal's hands were on the back of the lion's head with the tentacles emerging from his sides wrapping around Damascus' arms to hold them in place and remove any chance of interference, and the deer moaned in desperate elation as he stuffed his symbiont-granted, mobile and seemingly self-aware erection into his friend's waiting muzzle, and started to hump Damascus' face without restraint.

The lion's eyes bulged as he felt the deer's substantial erection start ploughing into his muzzle, hitting the back of his throat with every stroke right from the word go and making Damascus glad that he was as experienced with Skal and his unique anatomy as he was. He didn't choke, he didn't fight it. He just lay there with his friend straddling his chest and began to slurp and suckle at the cock face-fucking him as best he could, blushing as he felt Skal's balls slapping against his chin and shuddering as he felt the symbiont's prehensile cock twitching and curving inside his muzzle at a perfect angle to let itself sink to the very hilt inside his maw, and ensuring that suddenly he was deep-throating Skal with every stroke of the deer's newest and most savage humping.

Eyes rolling back in his head as he heard Skal crying out louder and ever more obscenely in the mindless lust which the symbiont was driving him to experience, Damascus felt his own cock swelling as he was used so deliciously by his friend. Skal, or rather the stag's symbiont seemed to recognise this too, for while the tentacles holding his arms down and the enhanced cock stuffing his maw remained fixated on their current duties, the two tentacles emerging from Skal's backside began to worm their way under the waistline of Damascus' trousers and proceed to roughly, mercilessly tear away the fabric of his entire crotch with what felt like almost no effort at all. They tugged and ripped at his trousers and the underwear beneath them until his throbbing, rapidly stiffening cock was fully exposed, and Damascus gave a helpless cry of pleasure around Skal's still furiously pumping cock as one of those thick, slick and oozy tentacles wrapped itself around his burgeoning hard-on while the other slipped down past his balls and between the crevice of his buttocks.

"Mnhnhhh!! Mnnghhddnnhhfgh..."

The lion began to gurgle, to cry out through the thrusts of the deer's unyielding, unceasing cock as bliss began to surge through his own body, one of Skal's tentacles starting to squeeze and masturbate him like a boa-constrictor encircling and squeezing its pray while the other probed into his ass and began to pump him full of lubricating fluid while exploring deeper and deeper, soon quivering and wriggling deliciously against Damascus' prostate. He tried to keep up, to continue sucking upon Skal's cock while not letting the force and speed of his friend's muzzle-fucking overwhelm him, but soon it was all too much, and for the first time in quite a while Damascus lurched as he gagged upon the cock humping deep into his throat while he tried to cry out yet again in his own rapidly building ecstasy.

Immediately, to Skal and his symbiont's credit, the deer withdrew as Damascus coughed and fought to catch his breath, but the lion could see the effort it was clearly taking Skal to restrain himself and the entity controlling his tentacles with every passing second. Both the tentacles on his arms withdrew and instead wrapped themselves around Skal's cock, forming a makeshift fleshlight of sorts to milk the deer's shaft as he humped at the air with a strained, pleading bellow, but as Damascus regained a little control of his breathing and cleared his throat one last time, he could feel how frustrated and desperate even this brief denial was making Skal's other half. The tentacle around his cock was squeezing tighter and tighter as though trying to glean pleasure for itself from Damascus' own erection, and the one in his ass was pressing deeper, harder, faster, rendering him almost as breathless as he had been while choking on the deer's own cock. He knew what Skal needed. He knew what both his friend and the symbiont itself needed in order to let them both rest for at least a little while, and in that moment, both as a loyal friend, a lover and of course someone being driven wild with pleasure by two tentacles assailing his own nether regions, Damascus knew that he was ready to give Skal precisely what he needed.

"Fuck me, Skal!"

The lion begged as the tentacle in his ass rubbed fiercely against his prostate once again, and a thick spurt of pre-cum erupted from his cock as it was pumped and squeezed harder and harder by the stag's other actively working tentacle. He opened his muzzle and drew in a ragged breath to cry out again, but a second plea proved utterly unnecessary. Instead a cry of shock and delight escaped his lips as both the deer's free tentacles and Skal's arms reached out and grabbed at him, roughly flipping him over from his back to his belly as the stag scrambled off of him, and without warning hurriedly pulled his slick, well lubricated tentacle all the way out of Damascus' ass. The lion blushed and moaned as tentacles encircled and wrapped around his limbs to pull them into their desired configuration while Skal's arms reached under his stomach and pulled him up until he was resting on all fours. Barely a second later he felt Skal mount him, looming over his back and hunching around him. He gurgled in blissful anticipation as one of the deer's tentacles stuffed itself back into his muzzle and began to spurt thick streams of a rather pleasantly sweet, sticky fluid down his throat, while another wrapped around his cock once again. The remaining two encircled his midsection as though locking him together with the deer, and just a moment after that through a combination of Skal's desperate, mindless humping and the stag's prehensile cock's more active attempts to seek it out, the lion roared as his friend found his mark, and began to sink his hot, lengthy and symbiotically imbued cock deep into his ass.

From that point onward, Damascus was every bit as lost to the lust of what was happening as Skal himself. The combination of the deer's instantly rough, mercilessly swift fucking with tentacles added to the mix to hold them close and drag them back together after each time the stag withdrew, and the constant squeezing and rubbing of the lion's own erection in tandem ensured that no matter how intense Skal's fucking might have been, the combined stimulation of Damascus' cock alongside his aching, overwhelmed prostate was more blissful still. The deer's cock knew exactly what it was doing, and with every thrust it twitched and twisted its prehensile form to ensure that it was granting maximum stimulation to the ass in which it was being repeatedly and passionately buried.

Deep, guttural snarls and bellowing cries of pleasure rang out ceaselessly around Damascus' workshop, the lion's roars admittedly muffled somewhat by the tentacle being eagerly suckled upon as it too fucked his muzzle, though not quite as deep into the lion's throat as Skal's cock had reached. His hands scrabbled and clawed at the floor below, the claws of his flesh and blood limb doing little more than leaving tiny scratches in the woodwork, but his cybernetic limb leaving much deeper gouges in the ground as close by the floor was painted with spurt after copious spurt of Damascus' pre-cum. Already the lion could feel his orgasm building, rushing rapidly, helplessly towards him like a bus whose brakes had been cut. He had no way of knowing how close Skal might have been, the deer's cries having been at the same extreme, wild and desperate end of the spectrum right from the start. Just as the euphoria of his own orgasm was threatening to overwhelm and consume him though, Damascus felt the writhing prehensile shaft inside of him suddenly stiffen and straighten, as though losing control of its own shape-altering abilities for a brief while. He felt Skal's fucking grow somehow faster than the already brutally intense ploughing the stag was already delivering, and the lion swore that even as he felt the other man's heavy balls slap roughly, deliciously against his own in the throes of their unhinged and unrestrained fucking, he could feel something swelling and writhing around within them, preparing to be unleashed deep inside his own helplessly bliss-stricken body.

Whether intentional or not, whether trying to ensure he was helpless to resist or not, it was only a second after Damascus' own orgasm began to crash over the lion that Skal too began to cum. An earth-shattering roar echoed around the workshop as Damascus' cum began to paint the already pre-cum glistening floor beneath his trembling body in hot, thick ribbons, the tentacle wrapped around his shaft continuing to squeeze and masturbate him with the same urgent, tightly clutching caresses all the while. The tentacle in his muzzle withdrew to let Damascus roar and howl freely in his ecstasy, a final hot, thick spray of its own sweet juices painting the lion's flushed, blissfully contorted face. After that though, Damascus really wasn't aware of anything that happened to his own body. He could feel the pleasure. In truth he could feel nothing but the pleasure of his orgasm crashing through him. But beyond that, all his focus from that instant onward was directed not at himself. Not at his own body's quivering and writhing and uncontrollably cumming self, but at Skal. At the stag who with a bellowing, ear-splitting cry of his very own buried his rock hard and throbbing cock to the hilt inside of the lion one last time, and locked himself against Damascus with his free tentacles as he began not simply to cum inside the lion, but to pour forth something far more copious, thicker, hotter, and more distinctly mobile than just cum deep, deep into the lion's defenceless, pleasure-stricken body.

" Yes!"

Damascus roared, not caring in the slightest what it meant for him, for his future and his own autonomy as after five or six hot ropes of cum were unleashed deep into his ass he felt that wriggling, writhing form spurt forth from Skal's cock and begin to wriggle and swim its way through his cum-filled innards.

"Y-yessssss, d-don't stop!"

The lion wailed as Skal just kept on grunting, shuddering and cumming far harder, longer, and far more in terms of sheer volume than he or any man regardless of size or testicular capacity should have been able to cum, his own orgasm matching the deer's in duration, cock still twitching, prostate still throbbing with ecstasy even though his own balls were long since emptied of every last drop.

"Please... o-ohhh god, Tina... please!"

Damascus' eyes widened as he cried out a name other than Skal's own, but not in shame, not in embarrassment. Simply in realisation as he acknowledged who it was he was begging for more in that moment. Not the stag shuddering and moaning above him, but the one who had driven him to these extremes of passion. The symbiont themselves, to whom suddenly and intensely Damascus felt far more intimately connected.

The lion growled, moaned, and finally howled in rapture as without warning or reason he felt something settle and latch on deep inside of himself, and all of a sudden his cock began to cum, to gush with renewed volume and abundance of seed once again.

"Skal! Tina!! O-ohh god. Ohhh god, yes!"

He roared, his head sinking down in overwhelmed ecstasy, and his glazed eyes watching in wonder as he saw not thick white ribbons of cum pouring forth from himself, but more transparent, glistening strands of fluid like those that had been gushing down his throat and more recently over his face.

Perhaps he should have been scared by that sight. Nervous at the idea of something happening to him like he knew had happened to Skal. Maybe, had it not been for the young symbiont now affixed deep inside of him and all the pleasure crashing in impossible, purposeful abundance through his body, he would have been. But as true as all of that was, Damascus wasn't scared. He wasn't upset or frustrated or nervous about what was happening to him.

As he knelt there with Skal still panting, grunting and cumming ceaselessly within his ass, and felt his cock spasming and lashing the floor below with yet more and more blissful strands of seed regardless of its source, the lion had no time for worry. No time for fear.

He just wanted himself and Skal to keep on cumming, and cumming, and cumming for as long as their internalised companions would allow them to. And then, as soon as they were spent... to do whatever he could to help Skal and Tina recover with all due haste, so that together they could do it all again.
