Chapter Text
A cold wind trickled in through the open window. Sitting upright in his bed, Eiden stared at the empty space next to him, residue heat still radiating from the neatly arranged sheets.
He would have frowned in confusion if this hadn’t happened several times in a row over the last two weeks. Every time he would pull Yakumo into bed, have a roll around in the bedsheets with him, and after he fell asleep Yakumo would simply get up, dress himself and slip out of bed soundlessly. Sometimes he caught him in action, and those times Yakumo would murmur something in his ear and placate him until he groggily went to sleep again. Not this time, though. This time he’d waited for him to leave entirely before getting up.
His skin was still sticky from the sex they had a few hours ago. That was the bad thing about summer here; air conditioning didn’t exist in this world, and if he was hot he could rely on nothing to cool him down. Throwing the covers off his body, he gingerly placed a toe on the floor, feeling a numb ache run up from his inner thigh. Shy as he was, Yakumo absolutely did not pull any punches when it came to pummelling his ass with his cock.
Eiden grimaced as he pulled on his shirt and shoes.
The door clicked lightly as it unlatched. He took the means to keep quiet at first, but found it unnecessary when he loudly tripped over himself and still failed to alert Yakumo to his presence. He tailed him to the front doors of the inn, which Yakumo pushed slightly ajar to squeeze himself through. Eiden followed. He thought he saw the receptionist at the counter shoot him a dirty look. No doubt she thought he was going for a midnight rendezvous with his lover. People often had that assumption back at the mansion, what with Yakumo being responsible for grocery shopping and everyone at the market knowing about a certain master he cooked and cleaned for. Eiden was too lazy to correct them anyways, so the rumour stayed— that he was keeping the descendent of the Great Serpent as his wife.
They weren’t wrong, in a sense. He was technically keeping Yakumo hostage with Aster’s memory altering magic that sent the man off from the village he came from. Despite Yakumo never complaining about his current arrangements, he would still sometimes feel pangs of guilt keeping him around. It was probably the innocent air about Yakumo that inspired him to feel this way; it felt more like deceiving a child to stay than convincing, say, a distinguished member of the church or the royal knights to work for him.
Although he wasn’t so sure about Yakumo being completely innocent right now. There was definitely something Yakumo wanted to hide. The man had headed straight towards the deep of the forest, and Eiden wasn’t very sure about sneaking along behind him and risking getting lost in the woods. He could directly ask Yakumo tomorrow what he had been doing last night. Or ask Morvay and Aster to accompany him another night when Yakumo runs off again. He squinted through the darkness and evaluated his options. If he followed behind closely enough, technically he wouldn’t have any problem going back if he just trailed after Yakumo.
He slunk between the trees after him.
Yakumo, unbothered by the tangled undergrowth, weaved his way through the forest with set determination. He seemed to know where he was going with a fierce determination, and as Eiden struggled against slipping on the wet moss of the earth his curiosity about Yakumo grew. Breath ragged from exertion, he climbed over a large, twisted root of an ancient-looking oak tree, cursing the years of office work that had whittled down his muscle strength. By the time he managed to get on both feet, Yakumo was already lost from his field of vision.
Well. He whipped his head around, feet rooted to their position. He could hear nothing in the dark of night, only the wind that whistled shrilly between the branches of the trees. There was no telltale crunch of footsteps on dried leaves, nor crack and squelch of moist dirt that signified the presence of another living being. A numbing panic swelled momentarily in his chest before he took in a deep breath and tried to keep his voice steady:
“Yakumo?”
He imagined Yakumo halting in his tracks. He’d traversed for about twenty, no, thirty minutes or so, and there was no way he could return without help. He had to get Yakumo to turn back.
“Yakumo,” he called, still hesitant to move. If Yakumo could arrive at his destination and still return to the inn before dawn the nights before, it was highly likely that he came and went on the same path. Moving away from this spot would get him truly lost.
Minutes passed before an unusual cry echoed from a distance, followed with a frenzied round of barking. Wolves, Eiden thought, a thin sheen of cold sweat beginning to form on his skin. His soles began to slip on the soil as he readied himself to run. Though at the last moment he let out the uncomfortable breath he’d been holding. Yakumo. It might be him that was in trouble.
He knew it was a bad idea, but regardless slashed a gash into the bark of a nearby tree to mark his location and broke into a brisk walk towards the origin of the noise. He thought he could hear the sound of flesh tearing, but couldn’t be sure with his heartbeat pulsing in his ears. Swallowing a mouthful of sour spit, he made his way through the forest as silently as possible. His limbs were tense, fear and panic sending a dizzying rush of blood into his brain. As he drew towards his destination, the baying became more distinct and he could just about make out how many wolves there were.
A clearing was before him, and peering between a couple of trees he found himself staring at a pack of wolves. All of them came at least to his waist in height. They were circling something and whining to each other, and on the ground he saw two carcasses bleeding darkly into the soil. Whatever had killed them was apparently surrounded in the middle. Hackles raised, the wolves padded towards the centre of the clearing. Their claws, unsheathed, left scars in the dirt.
One of them pounced, and in the gap it left behind he saw the creature it was attacking.
The serpent’s fangs flashed in the dim moonlight. Its jaws opened at an inane angle, pale and glinting with blood. Nimbly, it dodged the wolf and within moments clamped down on its neck, snapping it with a sick crack. The wolf’s body spasmed violently as it was thrown to the ground. It was at least ten to twenty meters long, the diameter of its body comparable to that of a human’s. Another wolf tried to go for its body, and with impossible speed it turned towards it, pupils blown. With a flick of its tail it sent it caroming against a tree, and seconds later it had coiled a section of itself around the wolf’s body, effectively strangling it. It hissed at the other wolves while their brethren gasped for air, twitching in its hold. A pool of blood marred the ground beneath its jaw.
Just as it was about to snap at a wolf again it paused. Raising its head, it made an action as if sniffing the air, and with horrifying accuracy moved its head towards Eiden’s position. It couldn’t have possibly seen him, but he staggered back anyways, shaken. It couldn’t— it looked as if— it was definitely Yakumo, wasn’t it? His throat felt like parchment as he watched the serpent dart its pink tongue out of its mouth to taste the air.
It was hungry. That he knew. It eyed the predators in front of it like prey, cornering them with its twisting, patterned body. The white scales that lined its diamond-shaped head were flushed light pink from excitement, and when it shot down to bite it did so voraciously, as if growing impatient for its meal. From the bruising colour it left around each bite Eiden knew it was venomous. A wolf cried pitifully as it surrendered under its crushing grip and the forest went silent once more, save for the rasping of its scales against each other as it released the strangled cadaver from its knotted body.
He couldn’t tear his eyes away. The serpent began feeding on the bodies, though not in a way that was typical of snakes; it coiled around them and began flensing them with its jaw, as if it disliked the taste of fur on its food. One by one it did the same to, and with astonishing dexterity crushed the flesh before swallowing the carcasses whole. By the time it finished, Eiden’s shirt had become completely soaked with sweat. Looking almost pleased, it opened its jaws once again and popped them in succession to realign them. Then it blinked and turned its attention to Eiden’s direction.
His knees buckled for a split second. His heartbeat rate shot up and he instantly pivoted on his heel to run, but he’d missed the serpent tail that had crept up behind him unnoticed. He felt a ring of pressure squeeze around his ankle and nearly stumbled, but caught himself on a tree trunk at the last moment. Steadily, the tail curled up around his lower thigh, slowly but forcefully dragging him backwards. He cursed as he tugged his leg back, but no amount of force did any good. Exhaling, he looked at the tail’s owner sharply.
It didn’t look like it was going to attack him any time, which was good, but he would have had to be lying if he said he wasn’t going to have a panic attack any moment now. It towed him towards the clearing, where the entirety of its length laid in clear view. Its body filled half of the space, and along its belly Eiden could see the vaguest outlines of the carcasses it had just fed on. He strained against his bonds to no avail. It lowered its head towards him and flicked its tongue.
He’d heard from Yakumo that snakes used their tongues to assist olfaction, but seeing it in action— directed at him, no less— was still jarring. Up close, he saw that its irises were a bright scarlet, its slitted pupils quivering to adjust to the light. Its jaws smelled faintly of copper and blood.
Its head was dipped towards him, awaiting. Eiden swallowed. Licking his lips tentatively, he raised his hand and cautiously placed it on its snout. It nudged him further, encouraging him. Its scales felt warm beneath his hand. A sigh escaped from his throat as he tried to digest the absurdity of the situation.
“It is you, right? Yakumo.”
The serpent butted him with its head fondly. If it were a feline, Eiden thought it might have been purring now.
“I can’t say this form of yours is calming in any way.” He gave a dry laugh. “Particularly after seeing you… eat.”
Yakumo didn’t seem to respond and instead licked his palm. His tongue was warm and wet, and left a glistening stain on Eiden’s palm. His saliva gave off a certain aroma that Eiden couldn’t identify. It didn’t smell bad, to his surprise, though his skin began heating up a little while after. He might be allergic to certain compounds in it. That wasn’t good.
“Let’s get you back to the inn, shall we? If it’s a diet problem, Aster should be able to handle it… We’ll just have to make up a legitimate reason to purchase that much meat… huh?”
He felt Yakumo’s tail tighten around him. He hadn’t realised that the serpent had ventured up to his waist. He gripped Yakumo’s thick body that had wrapped itself around his torso, shoving at him futilely. The serpent flexed beneath his hands, sinewy and warm to touch. An unnerving thought began to form in the back of his mind.
“Are you listening to me?” He grasped the serpent’s head from below, cradling its jaw between his fingers. Undeterred, Yakumo moved deftly to run his forked tongue along Eiden’s cheek, down the ridge of his jaw, then took the hem of his shirt carefully between his teeth.
“No, no, you can’t do that.” His resistance was easily ignored. Yakumo continued pulling at his shirt as Eiden tried to heft his snout up and away from him. “As enthusiastic about sex as I am, I’m not sure if, if doing it while you’re like this is okay—“
His shirt tore as he finished his sentence. So much for reasoning with a snake. He wasn’t quite sure if Yakumo understood him. Anyhow, that was a lesser problem, because despite logic sounding ten different alarms in him he found himself getting aroused with Yakumo’s scales rubbing against his crotch. There was no way this could have happened naturally. Yakumo’s damned saliva was a— he gritted his teeth as his cock was given a light squeeze— an aphrodisiac.
His breathing became heavy as the tingling sensation on his skin spread to his groin. Every inch of skin touched by Yakumo’s tongue burned. Strength drained from his legs and he nearly collapsed, supported only by the shifting bundle of serpent muscle that was now wrapping itself around his wrists and ankles. The fabric of his clothes gave way easily under Yakumo’s jagged teeth. He inhaled, shivering, as the spit-coated skin of his abdomen met air. His nipples hardened, pink and perked up against his chest. Yakumo’s eyes nictitated briefly in interest. His forked tongue oscillated, gently flicking at Eiden’s chest. Eiden’s eyes widened as Yakumo licked a sloppy strip across his chest, paused to savour the taste of Eiden’s sweat, and curled his teat into his wet, rough tongue.
Eiden groaned. The texture of Yakumo’s tongue was strange yet in a way oddly arousing. It wasn’t rough like a human’s but almost completely smooth. Curled around his nipple, it mimicked the sucking action of a human mouth, swirling and rolling his nipple in rhythmic pumps. The forked ends grazed the tip of the nub and sent him arching instinctively into Yakumo’s mouth. Yakumo’s aphrodisiac saliva didn’t help at all; his left breast felt as if it was on fire, immolated by the tiniest stimulations brought by Yakumo’s ministrations. He could tell how Yakumo was getting frustrated at his lack of ability to mark him from how he was mouthing at his skin, fangs retracted. Though that, too, left a ring of bruises around his nipple. By the time Yakumo moved on to his other teat, his breast was already swollen, nipple puffy and abused. Snake spit pooled in his sternum, dripping down his stomach and leaving a glistening trail along his abdomen.
Shackled at his wrists and ankles, he was gently laid onto the grass on his back. He was bound like python prey, with Yakumo twining around his waist and completely restricting any sudden movements. His cock, still confined to his pants, twitched as Yakumo played with his nipples, precum soaking through his underwear. He rutted upwards, desperate for friction. A segment of Yakumo’s body looped itself around his cock, rubbing the shaft through his clothes. The tapered end of Yakumo’s tail slipped itself under Eiden’s pants. Eiden seized as the rough sensation of his tail ghosted over his glans, scales compressing and rolling over the leaking tip of his cock.
Precum dribbled down his cock, acting as lubricant to allow Yakumo to slide his body over his throbbing dick. Yakumo was milking him, each constriction around his cock sending an inexplicable impulse to cum through Eiden’s crotch. The tip of his tail circled around his urethral orifice, shallowly dipping into the slit and forcing an intense wave of arousal up Eiden’s spine as he was denied release. Eiden was moaning incomprehensibly now, pupils unfocused as saliva oozed down the corner of his mouth. Yakumo shifted behind him and he felt a bumpy, swollen structure trace its way from his thigh to where his spine dipped into his ass. His eyes widened.
“Ah— that,” he gasped as Yakumo’s cock prodded against his asscheeks, “won’t fit!”
To his terror, he felt another similar structure press against his thigh. A hot liquid trickled from it, smearing the milky expanse of his inner thigh. Yakumo’s tail retreated from his cock and began making its way to his back, teasing and circling the tight ring of muscle between his buttocks as it arrived. Eiden’s legs were brought close and the uneven texture of Yakumo’s cocks slowly pushed itself between his thighs, rubbing his perineum at an agonising pace. Obscenely, Yakumo mounted himself on him, humping his legs languidly and secreting thick, opaque seminal fluid between and over his thighs.
His mouth never stopped, either, still biting and tonguing at Eiden’s nipples. Occasionally he moved to lick at the shell of his ear, earning him an excited clench around his cocks. Carefully, he navigated his tail to Eiden’s anal sphincter and teased at the hole. It quivered as he slipped the tip inside. Eiden moaned below him, hips adjusting to allow him better access. Yakumo found his prostate quickly and thrust himself into it, brusquely massaging the bundle of nerves. Eiden made a choked sound from his throat. He had never been so stimulated before, his cock and prostate and nipples played with for so long—
He came without warning. He could barely see through his tears as orgasm ripped through him. Toes curled and back strung tight as a bow, he came all over himself, cum spurting in white ropes across the grass and onto Yakumo’s black-ochre scales. Everything within him felt hot and scalding. Desperate, he clawed at his restraints, hoping to find something to hold onto as Yakumo stroked his cock through his hypersensitivity. His thoughts reduced to a low buzz as a wave of satisfaction burgeoned through him. His limbs, slack with pleasure, suddenly seized as Yakumo blocked the head of his cock.
He clenched abruptly as Yakumo began vigorously fucking him with his tail. “No,” he managed through his post-orgasmic haze, “I, I can’t— if you do that, I’ll—ah—!”
The desire to release was infinitely similar. Holding it in was unthinkable at this point. He was sure Yakumo knew exactly what he was doing by ramming himself against his bladder, and Yakumo was going to succeed. The shame of it, the intense want to let go took the reins as he was spread apart, cock directed towards the ground.
A stream of piss surged from his cock. He cried through it, sobbing and moaning, cock hard and florid as urine gushed and soaked into the earth. There wasn’t anyone around to see, yet he wept anyway, the pleasure brought by micturition overpowering his control over his body. He wasn’t allowed to collapse. Yakumo held him steady, hissing softly into his ear. The tail in his rectum pulled out with a lewd pop.
Eiden panted heavily. Tears rolled down his cheeks as he blinked reflexively. He didn’t even notice Yakumo’s cock nudging at his ass until Yakumo was trying to push in, and even then he had no strength to resist. The only thing he could do was relax and allow him to enter.
Eiden groaned through gritted teeth. Yakumo was so thick, he didn’t think it could fully penetrate him. A wild thrill coursed through his veins as the girthy, irregular shape of Yakumo’s cock registered and he knew, viscerally, that he was copulating with an animal. Stretched to his limit, he sighed blissfully, waiting for his rectum to accommodate Yakumo’s size. Yakumo, patient as ever, gave him the time to adjust.
Gradually he shook his hips in want of friction. Yakumo complied enthusiastically, first carefully drawing himself out and pushing in, then thrusting deliberately to aim at Eiden’s prostate. He was so huge Eiden could see the bulge of his hemipenis through his abdomen, and apparently Yakumo was pleased at seeing him filled up too as he began compressing his own cock above Eiden’s belly. His other cock remained between Eiden’s thighs, fucking him beneath Eiden’s cock and rubbing it along the veins underneath the shaft. Eiden’s thighs were so wet with his and Yakumo’s fluids he could hardly discern his skin from beneath the milky glaze of their cum.
Eventually Yakumo quickened his pace, plunging in Eiden’s ass with fervour and twining his body around Eiden’s torso. It was instinct for him to do so, to lock him down and breed him, to coerce the female into bearing his offspring. Eiden responded with equal enthusiasm, arousal evicting all conscious processes from his mind and sending him gasping and shaking into Yakumo’s embrace. Pleasure mounted ferociously in him as he sobbed Yakumo’s name like a mantra, begging him to cum.
Jaws clamped around Eiden’s shoulder, Yakumo came. His cum didn’t come splurging but steadily poured from the tip, filling Eiden’s ass and creaming his insides. Eiden came at the same time, shivering and senselessly moaning through it all, cock straining and dribbling pathetically after spilling a copious amount of cum onto the ground. Fuzzy with contentment, he felt Yakumo’s cum filling his ass millilitre by millilitre, coating his insides with his dense, viscous semen. He tried keeping all of it in when Yakumo pulled out, but it leaked out of him anyways, dripping down his ass in spurts.
Eiden was utterly spent. Yakumo was not. He let him rest for a while, nipping and coiling around him affectionately. Before long his hemipenes were hard again, and he rubbed them against Eiden’s ass, aroused and demanding for another round of copulation, this time with his other cock. Eiden weakly resisted, though in vain. Yakumo, entangling him with his enormous body, hissed lovingly into his ear.
They continued to fuck all night, until morning. By the time the sun rose and shed its warm glow on their naked, knotted bodies, Eiden had all but nearly fainted from exhaustion. His abdomen, having bore multiple rounds of Yakumo’s ejaculations, rose from his flat torso with a slight swell. Bruised and pink from the aphrodisiac, he looked as if he had been through a fight. Yakumo, still wound around him, gently licked the sweat off the nape of his neck.
Eiden didn’t hear the sound of human footsteps approaching. Yakumo coiled around him tighter and raised his head cautiously.
Aster and Morvay led the group into the clearing. Olivine sucked in a sharp breath at the sight, while Edmond unsheathed his sword in a single practiced movement. Yakumo’s pupils constricted. Hissing, he bared his fangs at them, Eiden tucked away against his belly. Blearily, Eiden opened his eyes.
“Master Eiden is trapped by that beast—“
“…think that’s Yakumo.”
“…and let him be strangled?”
Eiden struggled to comprehend what the voices were saying. With difficulty, he inhaled a lungful of fresh air and called out:
“Don’t do anything yet—“
“You see the direness of this situation!”
“He’s alive, isn’t he? There must be another way.”
“Hmm… master would be upset if Yakumo died.”
Yakumo hissed at them threateningly. Through his blurred vision, he saw Aster approach, and almost instantly Yakumo lunged at him. Edmond’s sword clanged pristinely off Yakumo’s fangs and a sphere of blue essence gathered urgently between Aster’s fingers.
In a brilliant flash of light, Eiden went under.
Waking up again was an exhausting task. Despite being healed with magic, a deep, uncomfortable ache still had seeped itself into his bones. Wincing, he stared at the ceiling of the mansion, wondering how many days it had been since he’d passed out. A glass of water stood on his bedside table and he reached for it, throat parched from sleep.
His arms and fingers trembled as he drank. What had he been doing before he passed out? Something about an enormous snake. He leaned forward, ignoring the pain that pierced through his ass and thighs. Yakumo. They’d attacked him. Oh no.
Just as he was about to get out of bed, the handle of the door to his room clicked. Morvay ducked his head inside and raised his eyebrows at Eiden, grinning.
“Master, you’re awake!”
“How long was I out?”
“Five days.” Relief was written all over his expression. “We thought you were going to leave us back then.”
Eiden smiled apologetically. “Ah, well, I’m sorry about worrying you. But nevermind that for a second. Is Yakumo… alive?”
Morvay furrowed his brows. “About that.”
“Is he?”
“Yes, but he’s… um…”
Eiden pursed his lips. “Injured grievously.”
“No, he’s completely fine if we’re talking about physical health. He recovered pretty quickly after Aster knocked him out. As for what’s wrong with him, I think it might be better if you see for yourself.”
Eiden contemplated in silence as Morvay called Aster to inform him of Eiden’s health. Grimacing, he followed Morvay into the corridor and made his way towards Yakumo’s chambers.
He knocked before entering. The room he’d assigned for Yakumo was extremely spacious, and at the centre Yakumo was sitting quietly on his bed. Yakumo turned his head towards the door as Eiden opened the door.
Eiden sighed in relief. “I’m so glad you’re alright.”
Yakumo hesitated, then asked in confusion.
“I’m very sorry, but who would you be?”
