Chapter 1: A Bond Made with Blood

Chapter Text

A full moon loomed, larger than life amid the cloudless sky. God had hung it there as a reminder, as a trial. The beast slouched against the weight of its wounds. Its claws clutched at unraveling fur and came away black with blood. An oppressive cold seeped past the layers of the beast’s insulated coat. 

 

Hot breath hit the air in a cloudy vapor. The panting denoted stress and exhaustion. The beast needed water, needed to eat. Lights shone in the distance. Those yellow canine eyes could only just make it out. Their power was supernatural even in complete fatigue. The creature carved a path through the forest, dripping a trail of blood in its wake.

 

Massive claws scuffed across stone as the dirt path transformed into an intentional staircase. With each step, the beast seemed to become less and less. One heavy step after another resulted in shedding, in shrinking. Fur reduced itself to pale white skin. Giant claws receded to merely sharpened fingernails. That malicious maw seething with blood and rancor diminished into brutally sharp teeth hidden only by the pink of human lips. 

 

Yes, this beast gradually became man. His heart thudded slowly in his chest. Each second took its toll. Even under the weight of the full moon, he had lost the strength to maintain his beast form. He could see it, though. The silhouette of a house that sat atop the hill. He would make it. He had to.

 

Gravity pulled at him until he could struggle no longer. He collapsed and the stone welcomed him with a harsh blow. In a moment of clarity, the light of an open doorway cut through the haze. A figure stood over him, ominous and watchful. A mask concealed its identity. There was only a smile and the wolf felt very afraid. Then, the world went dark.

 


 

A dream pricked at the corners of the beast’s mind. One of carnage and blood lust. He did not rest throughout this night, not while the full moon pressed at his consciousness. 

 

“Poor puppy.” A voice crooned amid all the noise in his head. “You look absolutely parched. Here, drink this.”

 

Something warm dripped onto his lips. He licked and tasted blood. His body convulsed at the rancid taste. 

 

“Don’t be rude.” The voice was right at his wolf ears. They twitched in displeasure at the proximity. “My blood is full of vitality. It will serve you well.”

 

The wolf had a feeling the thing’s body was hovering right over him, but he felt no warmth, no peace. Still, he lapped at the blood reflexively as it continued to flow to him. The effects coursed through him like a panacea, alleviating the open wound that sliced across his bare midriff. 

 

He gasped under this forceful cure. “You- Vampire-” His hand came up to scrabble at the thin white fabric of the creature’s shirt. Any cohesive thought unraveled into a fit of coughing.

 

“My, my,” The monster teased, effortlessly batting away the werewolf’s hand. “Such a naughty lycanthrope. To be so bold after I saved your life.”

 

The wolf couldn’t hold himself upright. His body was taxed, though the pain was almost non-existent.

 

“Sleep well now.” There was that smile again, mischievous and self-satisfied. “You can kill me in the morning, dear.”

 

With that, he drifted off into another spell of slumber. This time, the sleep was restful.

 


 

The wolf came to immediately when the sun began to rise. He could feel the moon’s presence relinquishing its hold on him. He wrapped his naked body in the bedsheet before standing to his feet. Dizziness washed over him. He noticed the water on the nightstand and greedily gulped it down.

 

Bolstering his remaining energy, he shuffled out the room’s door and into what seemed to be a hallway. The design boasted of wood paneling and reddish tapestries. Candles were lit here and there, but they were largely unhelpful amongst the cavernous ceilings. He sniffed the air. A scent, acerbic and piercing, caught his attention. He felt at once calm, yet delirious. His feet moved against his will, driving him. He chased that feeling until he arrived at a large set of double doors.

 

A clawed hand wrenched open the door. He clutched the bed sheet close to him as he stared. The expansive master bedroom unfolded before him. This room was bathed in the light of many candles. The beacons of warmth scattered across desks and tables. They sat in sconces attached to the wall. Smoke hung in a haze above. The wolf immediately balked, his lungs aching. That scent from before cut through the overstimulation. The one thing that tethered him to this world.

 

“Now, how did you come to find me?”

 

He hadn’t noticed the figure sitting in a high-backed chair. It stood with a flourish, shucking off its cloak. Velvet pooled at the feet of that dastardly vampire. His savior so it seemed.

 

“I followed your scent.” His voice carried no inflection. He was scared that if he moved wrong, the creature would descend on him. 

 

The vampire no longer wore his mask. His blue hair was pushed back severely. It highlighted strong brows and a straight nose. His face was devoid of color. In its own way, this too was a mask, bloodless and sinister.

 

“Ah, I see. I’ve picked up such a smart stray.” Deep laughter bounced off the walls. The wolf’s ears twitched in annoyance. “Well, don’t just stand there. Come closer.”

 

Though every fiber of the wolf’s being pulled against the urge, something compelled him to move, to follow orders. He arrived at the vampire’s side, sweating from the exertion of resisting.

 

“Is something the matter?” The vampire feigned sympathy, “You look positively dreadful.”

 

“What have you done to me?” He snapped, trembling. “I can’t stop--shaking-”

 

“Yes, I see that.” His red eyes slid down the wolf’s bare collarbone. “If you’re that exhausted, you can sit.”

 

The suggestion alone wasn’t enough to warrant a reaction. He shivered and remained standing.

 

The vampire considered him with leering eyes. “Let me try something, then.” He motioned to chair. “Sit. I’m insisting.”

 

He landed in the chair, his full weight and momentum jolting the thing backward.

 

“Oh dear.” The thing didn’t sound very repentant, though his lip stuck out, pouting. “I seem to have turned you into my thrall. Oopsie.” 

 

The wolf growled, “You what ?”

 

“I forget that my blood has that effect on beings.” He shrugged. “Usually, it only impacts those with weak minds.”

 

He barked out a laugh, sardonic and dispairing. “I was at my weakest when it was given to me.” 

 

“If that makes you feel better.” The vampire started to blow out his candles, one by one. “I do hope you’re feeling better at least. You’d probably be fully recovered if you weren’t resisting things so adamantly.” 

 

Each light snuffed out like a life ending. He held his head in his hands. When he let go, when he stopped resisting, he could feel his sense of agency slipping away. He hated it, but he knew his fortitude was gradually dwindling. 

 

“Oh, it isn’t so bad.” The room was sinking into pleasant darkness. The wolf’s tension unraveled as it closed in. “I have no interest in the blood of a pathetic dog so you’re free to go at any time.”

 

The vampire’s words sparked a sudden burst of pain that shot through his being. 

 

No .” He hissed, still hunched over and clutching at his hair. 

 

There were only a handful of candles left. Dawn would be inescapable, soon, soon.

 

“Excuse me?” The vampire said, highly scandalized. Then, realization washed over his features. “Oh, you poor thing.” He made his way over to where the werewolf was sitting and stood, looking down at his trembling form. “It’s really all you want, isn’t it? To be useful?” 

 

He crouched to be at the wolf’s level, to gaze into his frightened eyes. 

 

“Shhhh,” Cold hands pushed his hair out of his face. “Tell me your name.”

 

“Tadashi.” He was surprised his foggy mind even remembered.

 

“Tadashi,” His voice whispered in hushed tones now as if speaking to a spooked animal, “You can call me Adam or Master if you’d like.”

 

The prospect sent a thrilling sensation down Tadashi’s spine. He didn’t want it, but he did, he did. A small whimper escaped his mouth and the vampire, Adam, chuckled.

 

“You’re so far gone, pet.” His fingers played around his jawline, the pad of his thumb brushing across his bottom lip. “Unfortunately, I don’t know how to reverse the effects. If I told you to go elsewhere, you would arrive at the destination and be so confused. Maybe it's a game we can play … Where you come crawling back each time  …” He brought Tadashi’s face up as the wolf endeavored to turn away. “Would you like that, Tadashi?”

 

“No.” Tadashi bit out.

 

“No, what?” Adam smiled.

 

The wolf couldn’t look away from those glittering eyes. “No, Master.” His voice came out with more certainty than he anticipated. 

 

“Good boy.” Adam released Tadashi and his head hung low. 

 

The vampire laughed. “Now, I’m just being mean. I’ll try to restrain myself. You’re just so fun to tease.”

 

With the admission of subservience, the wolf could already feel his body unwinding. He lolled against the arm of the chair, floating. 

 

“That’s no place to sleep, love. On your feet.” Adam pulled Tadashi upright and held him in place. “In any event, It’s past my bedtime. The sun is an absolute nightmare to deal with honestly.”

 

Even just being surrounded by his Master’s smell and presence eased the werewolf’s discomfort. They navigated over to the bed which was enveloped in thick, heavy curtains. Adam set Tadashi down on the bed, pulling the covers over his naked body. The vampire discarded his shoes before joining him. 

 

“Adam.” Tadashi rasped. He stared into the nothingness of the bed’s canopy.

 

A hand stroked at the wolf’s hair. “I’m here.” He said.

 

“Please, I want to-” He rolled over to gaze up at the vampire. A set of questioning red eyes looked back. Tadashi flinched and turned away. “I want to give you my blood.” He managed to say. 

 

“You honestly want that?” Adam didn’t sound harsh, just matter-of-fact.

 

“I don’t think-” Tadashi gained more confidence. “I don’t think I’ll be able to sleep without doing something to- to-”

 

“I understand.” Adam soothed. “It’s alright. Come here.”

 

Tadashi slinked over. The bedsheet tangled up in his legs. He boldly straddled the vampire, situating himself in his lap. He had started breathing heavily again. The mere thought of having his blood sucked sent him into a tizzy. His tail, which had been trapped by the blanket, began swishing around their legs.

 

“You look so inviting, dear.” A hand came up to rest lightly against Tadashi’s fluttering pulse. “You’re doing so well.”

 

“I just want to be useful, Master.” The words rushed out of him as if he had always felt this way.

 

“I know.” Adam’s hand applied more pressure to where he held him by the neck. “And you will be.” He affirmed. His mouth came up to kiss along the column of Tadashi’s throat. 

 

Tadashi moaned, uncaring. Shame didn’t factor into his world anymore. He was drifting into a delicious space where nothing mattered except his Master. His head tilted back to allow easy access as he felt teeth slot against his skin.

 

The wolf jumped when he realized that Adam had started stroking his cock. He didn’t know what he had done to deserve this, He hadn’t even realized he was hard. His needs had moved to the far recesses of his mind. Nevertheless, he met each thrust with a steady shake of his hips

 

“Hold. Still.” Adam gritted out and Tadashi whimpered. 

 

He did his best to calm down as the teeth returned to provide insistent pressure. He braced himself, waiting, waiting. In a flash of pain and pleasure, those fangs sunk deep into his throat. He could feel the blood leaving him, pulsing and hot. The moan that was ripped from him accompanied an orgasm so intense that he felt his vision go white.

 

The act endured as he came down from his high. The pumping pressure of being used and drained. He couldn’t get enough of it. His hands fisted into Adam’s shirt. He could cum again. In fact, he felt as if his orgasm never really stopped. Pleasure compounded pleasure in an intoxicating cycle.

 

Those teeth retracted once they were finished. Adam wiped at the blood that dripped from his lips.

 

“Let me, Let me.” Tadashi chanted before pressing his lips to Adam’s. He tasted himself within that kiss. Adam’s lips returned the sentiment fiercely. Their tongues met and the metallic taste permeated Tadashi’s being, his soul returned to him briefly.

 

Adam pulled away. “Thank you.” He said. The teasing from earlier had evaporated. 

 

Tadashi nodded, used and vulnerable.

 

“I’ll send for some food.” He laid Tadashi back on the bed as the wolf had slumped against his shoulder. “You’ll be able to sleep now?”

 

“Yes.” Tadashi smiled. “Thank you, Master.”

 

“Good. Rest now.” He stooped to kiss the wolf’s forehead. “Don’t worry, we’ll always be together from now on.”

 

Tadashi fell into a blissful sleep. His mind filled with the comforting touches of his Master. There wasn’t a single doubt in his mind that he would be with Adam forever.
