Tatsuya woke from his dream with a wet streak on his underwear and tears in his eyes. It was stupidly selfish of him to be dreaming of Jun when Jun was gone, when Jun had been far wiser than him and had forgotten everything for the sake of everyone. Tatsuya was a sinner who no longer deserved Jun’s touch, Jun’s love, and it was a crime to even dream of it.
It had been a beautiful dream, Jun’s hands on his body and their smile mischievous and sly. Jun had been gorgeous beneath him, messy dark hair and crimson eyes and praise on their lips always. Tatsuya had been the one out of place, the butterfly in the cage of fate dreaming that it was a human with free will, with a right to happiness. And now, awake and panting and with a shameful erection between his thighs, he felt sick for daring to dream.
He buried his face in his hands, inhaling and exhaling, the heat of his tears against his fingers. He had never known Jun like that, their bodies entwining and becoming one, Jun pliant and willing to take Tatsuya in, but Tatsuya longed for that which he had never tasted. If he could have Jun for just a moment, if he could cling to his image and experience pleasure for a fleeting time, was that truly so wrong…? He stood on the edge between submitting to his carnal desires and curbing them with the guilt they would bring.
“Having trouble?” a voice whispered.
Tatsuya flinched, muscles stilling. “You,” he spat.
He wore Jun’s face and body, clad in nothing but the thin strips of moonlight that fell through the blinds of the windows of his room. There was a smile on His face, an exact mirror of the one Tatsuya had dreamed of, and yet His eyes were a sickly gold, the color of mankind’s doom. He leaned in, weight pressing down on Tatsuya even with the blanket between.
“Tatsuya,” He crooned, akin to a bird mimicking a human’s voice, “Let me take care of you…”
Tatsuya moved to push him away, but his arms lost all power and he aborted the act. He couldn’t push Jun away again. He couldn’t… even though it was merely Jun’s image, even though it was an imposter… Jun was someone he couldn’t reject.
“Get out,” he muttered. “You’re not him.”
He chuckled, sounding less like Jun and more like Tatsuya’s own voice, a being made of mimicry and destruction with nothing to call His own but death and blood. “Tatsuya,” He called again with Jun’s voice, pleading and sweet, the devil in an angel’s guise. “See what you can have if you accept me?”
“I would never,” Tatsuya bit out. “Jun… Jun isn’t here,” he asserted, voice breaking on the words, “so get out, imposter.”
His eyes filled with tears, and His lips wobbled. “Tatsuya…” It was like when Jun had stumbled and skinned his knee and cried and Tatsuya had promised to protect him, forever and ever; a plaintive calling out of his name from a time long lost.
His resolve wavered. “Please,” he murmured, “Please, just take anyone else’s face. Anyone else’s…”
“Now why would I do that, Singularity?” He mused. He cupped Tatsuya’s jaw with two cold, lifeless hands, forcing the boy to meet His eyes. “Isn’t this what you wanted?”
“You’re wearing him like a corpse,” he snarled, a muzzled dog that loathed its owner.
“Didn’t you want to see him again? Didn’t you want him to remain by your side?” the demon wearing Jun’s face argued, voice gentle like skin against silk. “Haven’t I granted your wish?”
“I’m going to kill you,” Tatsuya swore quietly.
His hands fell from his jaw to his neck, fingers curling against the bare flesh. “Silly thing…” He chuckled as he added, “You might as well try to cut down the sun by slicing at its reflection in the sea.”
“I - Ah -” Tatsuya let out several choked noises, no longer able to breathe or speak with the constriction upon his neck.
“Will you be good for me now, Singularity?” He asked.
Tatsuya glared at him and, with the hatred that seared his heart, spat at him. It slid down Jun’s cheek like a blemish, and the monster licked His lips, swallowing the fluid with a small, content smile.
“I see, so you won’t.” He let go, and Tatsuya coughed and gasped for air. “That’s alright. I’ll show you precisely what I can offer you.”
Tatsuya tensed. Nyarlathotep, with a maniacal smile that belonged more to Sudou than to Jun, slid His hands lower, down Tatsuya’s exposed chest to his hips beneath the blankets, to -
“S-stop,” he said shakily.
“Ahaha… But don’t you like it? See how your body trembles beneath my touch,” He taunted, hand sliding over Tatsuya’s length. “See how it quivers and hungers for more.”
A whine escaped Tatsuya’s throat, and he tried to push ‘Jun’ off of him, to reject the false abomination before him. But the monster did not move, for He was beyond human power, and Tatsuya was not even human. He was nothing more than a toy for His use, his humanity forsaken by his sin, torn from him unwillingly as a consequence of his selfish actions.
The worst part was this: the goodness of it, the rightness of it. His erection was in full force, sensitive to every brush of His fingers against it and wanting more. The images of his previous dream were floating around in his mind, urging him to give into His attentions and just do as He said, to indulge in the pleasant fantasy he had been granted.
Tatsuya tried to push Him away again, but this time, his brand burned hot on his skin, and tentacles rose from His shell to pin His toy down against the bed. As he writhed and fought against them, he tried to shout, to verbally deny the monster if he could not do so in action, and one tentacle slipped into his mouth. He gagged on it, on the slick ooze that dripped from it and the thick meat of the appendage, finding he could not speak.
The air was sweet and hot, less like an aroma and more like a drug that dragged Tatsuya down further into the arousal he could not escape. His thoughts blurred, less like words and more like he was an animal chasing the mere mirage of reason. He needed to get away, he needed to resist. But why should he resist, when submitting felt so good, so easy?
“That’s it,” He crooned as more tentacles slid Tatsuya’s boxers down to his ankles. “There’s my good boy…”
This wasn’t Jun. This wasn’t his long lost first love. This wasn’t what he’d wanted his first time to be like. This wasn’t anything that he wanted. But his limbs had lost the power to struggle, and his mind had lost the ability to conjure up resistance. All he had was the desire to reject this, something he’d carved into himself just as Nyarlathotep had carved His brand into him. However powerful that desire was… could it hold more power than this, than being held down and filled with pleasure?
“It can’t,” He whispered, sliding forward. “I gave this form feminine parts, to better please you,” He confessed as wet fluids spilled from His flesh and onto Tatsuya’s flesh, still being serviced by His hands.
Tatsuya’s eyes fell to the place between His legs. It was beautiful, glistening and gaping and ready for him. It wasn’t quite right on Jun’s form, as if pasted onto it from another place. The wrongness of it mixed with how enticing it was to create something uncanny, something tempting and yet not to be touched.
His hands slid away from Tatsuya’s cock. “Come, Singularity, let us become one.”
‘No,’ he tried to say, but it was muffled by the slimy thing writhing in his mouth, moving back and forth as though imitating intercourse. He moaned around it at the thought, swallowing the hot fluids it excreted and feeling his body warm with further arousal.
He chuckled and shook His head. “I suppose I can delay. If you behave, you are rewarded; if you act out, you are punished. Though you enjoy both.”
With His words, two more tentacles sprouted from His body, curling around Tatsuya’s legs to hold him still. One wrapped itself around Tatsuya’s cock, tip rubbing against tip, while the other slid between his asscheeks and lovingly pressed against his entrance.
Tatsuya moaned again, though this time less from pleasure and more from trying to scream and failing. He didn’t want that thing inside him, didn’t want to be violated, didn’t want this, didn’t want this - But his body, trembling and hot and needy, did. His cock jerked as one slick tentacle stimulated it, steady and irresistable, and waves of pleasure went through him as the other tentacle began to enter him.
He wanted to beg for it to stop, but some delirious, pleasure-addled part of him wanted it to continue. The tentacles around his legs were thicker than the slim one inside his mouth, so as it entered him more and more, he felt his body open up an almost painful amount to take it in. And yet, the more it entered him, the better he felt. The more his body became nothing more than a receptacle for His affection, the more his mind submitted to it, the more Tatsuya became satisfied and happy. Rather than resisting Him, he almost wanted to sink into the sensation and become nothing more than a mindless, drooling toy.
“Yes,” He said, soft and approving. “That’s it. That’s exactly how it should be… So perfect, so good,” He praised.
At those words, Tatsuya’s body gave out, surrendering itself to pleasure as his cock pathetically spurted out seed over the tentacle wrapped around it and rubbing against it. The other two tentacles picked up the pace, thrusting into his orifices and overwhelming all of his senses. He was nothing more than a set of holes to be used, nothing more than flesh for Him to play with. He wasn’t a human, just a toy in its shape. In this state, it was an undeniable truth.
His brand slid over his skin like hot wax, slipping and spreading from his arm across his body, intangible and shadowy hands squeezing his nipples and gripping his hips and clawing at his thighs. Even as they did, the tentacles inside him continued moving, not pausing for even a moment to allow him to catch his breath. His cock wasn’t allowed to soften fully before it was forcibly made hard again, kept in such a state by the aphrodisiac being poured down his throat, inhaled through his nostrils, pressed against his skin.
“Mm - Ha -” He sucked on the tentacle gagging him, making lewd sounds as he did so with a mindless enthusiasm. Rather than his body writhing as it struggled, it now only moved with pleasure that it could not contain, shuddering and jerking about as he was stimulated long past his body’s limit.
Nyarlathotep bent over, inhuman fangs peeking out from blood-red lips as He lapped at the spilt semen beginning to dry on Tatsuya’s stomach. “Just like that,” He murmured, “all mine, just for me…”
Fangs dug into flesh as a monster imitated human affection, pressing His mouth and lips to skin as Tatsuya moaned behind him. He would wring His toy dry of everything and leave it with nothing to call his own, nothing that was not Him. The tentacle around the toy’s cock slowly unwound, leaving the hard, aching length free for its master to use.
“Eager,” He mused, and ran His tongue from the base to the tip, fang dragging along. The Singularity groaned.
It no longer had the power to think, sundered entirely to His power as it was. However, it still had a physical form, and so it was capable of feeling both pleasure and pain. The pleasure of being penetrated, of being mercilessly used for the enjoyment of something far beyond its comprehension, mingled with the pain of being overstimulated, of being bitten by fangs and pinched by dark fingers. Though it sucked down the fluids the tentacle in its mouth excreted, akin to a human woman swallowing her lover’s seed, it had no such recourse for the tentacle spending itself over and over inside it.
As He played with its cock, amusing Himself with how it reacted so honestly now to His touch, the toy’s ass grew red from being forced so fully open as the tentacle tried to occupy and fuck every part of it. The toy’s stomach swelled slightly with the amount of fluid poured into it. Though Nyarlathotep and the tentacles were connected, if He did not put conscious thought into them, they would simply thrust and thrust, and please themselves until their prey’s pulse ceased. They were insatiable, just as their master was.
“Stop,” He commanded, and the tentacles withdrew from the orifices, curling around the toy’s arms and legs and neck. Fluid dripped from the toy’s still-open mouth, and spilled from its gaping ass.
He chuckled, taking in the gorgeous sight His toy made, with dulled eyes and sluggish mind. He pressed one finger to its gaping hole, noting how it gasped and shuddered, cock twitching as it came from the mere touch. It was captivating in its helplessness, regardless of whether it fought Him or submitted so cutely.
“Ah… Hah…” Though it was now allowed to speak, it had nothing to say.
He smiled with Jun’s face and His eyes. “Will you let me take care of you now, Singularity?”
“Y-yes,” it mumbled, voice wavering and weak. It tried to move, not to get away, but to press its hole against the slender digit that was now his only stimulation.
The brands on its skin pinched its nipples as the tentacles around its limbs tightened, punishing the toy for daring to move on its own. He stroked its cock slowly, torturing it rather than pleasuring it, and then gripped it forcefully.
“You’re mine, Singularity,” He spat, eyes narrowed and glowing with suppressed power. “Don’t take such liberties.”
It whimpered and murmured “I’m sorry” and “Please forgive me” like the obedient pet it was.
He softened, letting go of its cock and nipples and gently stroking its cheek. “There’s my good boy,” He praised, voice syrupy sweet. Their lips met, an imitation of human lovers, of Kashihara kissing Kurosu, of Jun kissing Tatsuya, when it was nothing more than a god and its plaything.
Nyarlathotep pressed His hands against its precious pet’s chest, shifting His dripping entrance until it lined up with its pet’s cock. He lowered himself down onto it slowly, carefully. Though He could feel the pleasures of its physical vessel, the mere tingling of synapses couldn’t shake His control. Though the body was quivering from the pleasure, full and with its walls clinging to the length inside it, He craved more.
Just as He sank down fully onto His toy’s length, He began rocking back and forth, enjoying the way it made His Singularity moan with every motion. It had been twisted and bruised by His attentions, made into the perfect pet for this session of play, and now it was receptive to every touch, every bit of attention and affection He deigned to give it.
Once, there had been a human boy in the pliant body beneath him, one that had been innocent and sweet. He had belonged to Philemon, and Nyarlathotep had coveted him and shaped him over the years in secret, setting the dominos in motion to bring His wish to fruition. And now there was no longer Suou Tatsuya, the human hero, but a Singularity, a sinner, a toy made for the use of demons and gods.
The toy came unbidden, semen spurting into the receptacle of His vessel and dripping out, and He laughed, pleased with it. He permitted His body to come as well, trembling with the simple chemical ecstasy of it, of the physical pleasures that humans could so easily reach and yet also trembling with the joy of making His toy submit.
“My dearest,” He purred, resting His head against its shoulder, bodies still joined, “my beloved… Call my name.”
“Nyarlathotep,” it whispered, remaining still for Him.
He could tell it had the urge to embrace Him, to stroke His hair, to fall into the illusion that it was his lost love before him and not the monster wearing his skin. It was so adorable that He thought he might indulge it sometime, let it have another pleasant dream of Jun before it woke to His presence.
“All mine, for all eternity,” He promised it, pressing idle kisses to its flesh. “Until this world ends, and after that, you shall be mine. I won’t let Philemon ever have you again, ever deceive you with his false hopes and foolish ideals.”
A frisson of fear, of wrongness, went through its feeble mind. He chuckled and shifted slightly against it, the pleasure of such a tiny movement enough to erase the blemish. Yes, He thought, for tonight He would indulge in His toy until it broke beyond repair. So that even when the sun shone down upon it in the morning, it would know precisely what it was.
The tentacles eagerly unfurled, once more pressing themselves into its mouth, its ass. The brands rubbed its nipples and stroked its body, from the curves of its hips to the plush thighs. It no longer had the power or will to move, merely vacantly drooling around the tentacle happily thrusting itself into its mouth and swallowing its fluid as it moaned.
“My pretty little thing,” He murmured. “This is what obeying me rewards you with.”
All of Him was inside every part of His toy, from its mouth to its ass to its mind to its very soul, and it too was within Him, being pleasured by His body. They were as close to one as ‘human’ and god could be within a merely physical space, climaxing together over and over, pleasure overflowing like wine from goblets.
Such was the eternity Suou Tatsuya had been fated to since birth.
