Work Text:

At first, the entity’s nightly endeavors were purely curiosity. A longing to understand the machinations of the human body in all its parts and needs. A physical examination conducted in a scientific state of mind.

And Arthur Lester was the perfect subject. The man’s life had become more exhausting than he ever could have imagined in these past few weeks. The intense physical demands of this new lifestyle wore him out enough on their own, not to mention the intense strain on his mental state. His whole worldview had unraveled before his very eyes. Well. Their very eyes. It seemed like everyday Arthur was learning something that shouldn’t be knowable to any human. The cosmic horrors were taking a toll and the man was tired.

Of course, this worked out in the entity’s favor. Trapped in this unfamiliar body in an unfamiliar environment with no control. That is, except for two eyes and one arm up to the elbow. It was nice to be able to see, at least, but there was only so much to do when Arthur slept, eyes shut tight, blocking out one of the only luxuries afforded to that being inside of his head. So the being made do with what little he had left.

He was familiar with humans, but not intimately. During his time as The King, human lives were completely inconsequential to him. He cared for them no more than the average person may care for an ant. He, of course, knew their basic needs, how to make them tick, and how to dispose of them. But he had never spent much time studying a live specimen such as the one that was now so readily available to him.

With what little sleep Arthur was able to get, it was the perfect time for the entity to truly familiarize himself with the terrain. As his host drifted into a deep, impenetrable slumber, his left hand would ease its way under the covers and explore. First he’d place his hand over Arthur’s heart. Feel the rhythmic beating of it, sense the fragility of the life it was upholding. He also liked to feel the pulse in the neck. He’d lay a gentle finger down, feel the blood ebbing through the artery. How easy it would be to wrap that hand around and squeeze until the blood flowed no more. But the risk was too high. He had no idea what would happen to him if this body perished. So for now, the entity would restrain his urges.

Next the hand would slide its way up from the throat and feel the edge of the jaw and the rough stubble covering it, long overdue for a shave. He’d trace a finger along the mandible, even prod at the teeth through the skin to really get a feel for its mechanisms. He had a certain fascination with Arthur’s skeletal structure. The way his bones felt beneath the layers of muscle and fat and skin. How sturdy yet fragile they were. How much their construction and movement could affect Arthur’s abilities. Being a human seemed so frightening to this fragment of a god. It was so uncertain. The human body had far too many weaknesses.

Moving on from the face, he’d make his way back to the chest, lingering on the curves of Arthur’s ribs. The lack of food was taking a toll on his body, and even the entity could tell that Arthur was becoming unhealthily frail. He would have to work on that. Down past the ribs he would glide his hand over the stomach, guessing at where each organ should be located. The skin was softer here. More vulnerable. It was covered in a light scattering of hair that centered around the belly button and trailed down into a darker, thicker patch around the crotch. The hand followed this trail, slipping into the waistband of Arthur’s pants. He ventured a curious finger along the base of his cock, feeling the sensitive, soft flesh. Though this exploration was mostly conducted in the name of research, he couldn't deny that there may have been some curiosity about the sexual desires of the human body. He had never understood this disgusting need that humans have, but it was very useful leverage against them. Perhaps it could be explored as a method to further control Arthur during his waking hours. But for now, he would stick to these selfish delights.

 

As the weeks went by, in what felt like years, their relationship grew stronger. John even had his own name now. They had been through so much together that there was hardly anything too personal to share anymore. They had their routine: fight, ignore each other, make up, and go back to being the closest of friends. There wasn’t much else to do when they were literally trapped in one body together. A body that John had come to know very intimately, both inside and out.

As his relationship with Arthur grew more intimate, John could no longer deny that he had ulterior motives when conducting his nightly routine. With his consciousness already so consumed by Arthur’s spirit, he began to desire even more. Another level of connection that would be difficult to achieve with no body of his own. A hand and a voice would just have to be enough.

The pair finally had the luxury of their own bed in a room that felt safe enough to let their guard down for the night. Marie, though somewhat intrusive, seemed harmless enough. As Arthur made his way up the stairs from the little shop below, John excitedly pondered his plans for the night. He imagined scenarios in which Arthur had a more active role. What it would be like to tie his right hand to the bedpost… Make him beg underneath John’s grip… How nice it would feel to be the one in control for once.

When Arthur’s head finally hit the pillow, he was out almost instantly. John waited twenty minutes, just to be safe, and then pried his hand out from under the man’s weight. While John had become more needy for the feel of Arthur’s skin, he had also become more gentle. He cared deeply for his companion and felt a desire to take care of him. He would always start by caressing his face, pushing those brown locks out of his eyes. He would run a finger down his cheek in admiration for the warmth beneath. These little signs of life and humanity were of great comfort to John.

But with gentle affection came an equal amount of animalistic desire. He drew his hand down to the unconscious man’s neck, tracing the throat lightly with his sharp nails. How he desperately wished to leave a mark on that exposed skin, to show the world that Arthur belonged to him. If only he had his own body and mouth, he would cover him in deep bite marks and bruises. He would hold a tight grip around his throat, with two hands this time, and leave him gasping for air until the desperate detective begged to be taken. A low snarl escaped from John as he imagined the scene. Arthur twitched a little in his sleep.

He continued making his way down the man’s body, feeling the divot in his collar bones, the hair on his chest, the sensitive skin of his nipples. His biggest interest lied in the stomach. He felt a carnivorous urge to just rip him open, revealing the red viscera beneath. If he really tried he could dig his nails into the flesh and claw his way in. Slip those fingers into the slimy, moist cavern of Arthur’s abdomen. How warm those organs would feel, still pulsating in his hand. The thought sent him reeling, but of course this would always remain a mere fantasy. Despite his dark desires, John would never dream of genuinely hurting Arthur, let alone risking his life to do so.

He slid past Arthur’s stomach and crept his fingers beneath the waistband of his pants. He wanted to make Arthur hard for him. He knew it would be a risk, but he grabbed some lotion off the nightstand and began gently stroking Arthur’s cock. After a few seconds it started to grow as the blood came rushing downward. John worked his hand up and down at an increasing pace. He wished he could feel all the sensations of Arthur’s body. He wanted to know exactly how his touch would affect the man. What he didn’t expect, was to actually find out.

Arthur suddenly jolted awake. John felt the muscles of his body tense up beneath his hand.

“Fuck…” His hand froze in place, trying not to draw the man’s attention.

Arthur was quiet for a few seconds, taking in the unusual sensations. And then he felt the warmth circulating him under the covers.

“John….. What are you…?” His voice was weak with shock and came out in a quiet murmur.

“I… Arthur, I was just…” John had no idea what to say. In the early days, he had been concerned about the idea of being caught. But back then he wasn’t doing much more than satiating his curiosity, and besides, Arthur had always been such a heavy sleeper that he stopped worrying altogether. Now he regretted it.

Arthur lay silent and still for an excruciating few moments, as if in deep contemplation. Then his voice came back, stronger than before.

“Keep going.”

“I- Arthur, are you sure?”

“You heard me.”

And so he kept going. He slowly started working his hand back up and down the length of Arthur’s hard cock. Arthur made a low groaning sound and John picked up the pace.

“Do you do this often?” Arthur asked quietly as his left hand continued to service him under the blankets in the dark bedroom.

“More than I’d like to admit, my friend.”

“Every night?”

“Just about…”

“Oh you dirty bastard. You get off to violating me when I’m most vulnerable, huh?” Despite the gravity of the accusation, Arthur’s voice had a touch of amusement to it. “And here I thought you were just whiling away bored all night.” Another groan escaped him. “I think you’ve been enjoying my need for sleep much more than you’ve been letting on, John.”

John let out a sinister chuckle. “And I think you’re enjoying the idea much more than any sane man ought to.”

“We both know I am well past any chance of being a ‘sane man.’” Arthur shit his eyes in blissful content.

“Tell me how you feel, Arthur.”

“I feel… relieved. Relieved of an urge that I had almost forgotten I ever had. And I feel… ravenous.”

“Ravenous?” John suddenly froze.

“What.. Why’d you stop?”

“Arthur I have been trapped in your body for months now with nothing more than your sight and this hand. Now that I know I have at least some form of control over you, forgive me if I let it get to my head. I want you to feel just how powerless I’ve felt all this time. By the end of tonight you are going to be so ‘ravenous’ for release that you’ll be thinking twice next time you decide to ignore me. Now reach for the bag on the floor to your right.”

“...Why?”

“Just do what I say, Arthur.”

Arthur reached his hand down into the darkness until he felt the canvas bag on the floor. He pulled it up onto the bed where John could reach. John felt around inside and pulled something out before throwing the bag back down.

“Now Arthur, put your arm behind your head. And if you ask ‘why’ again you’re going to regret it.”

Arthur did as he was told and put his arm behind him, resting against the headboard. John maneuvered his own arm around and revealed the piece of rope that he had taken from the bag, which he then used to tie a knot around Arthur’s wrist and the bedpost.

“John, what the fuck are you do-”

“What did I just say about asking questions, Arthur?” His hand shot over to Arthur’s face and gripped his jaw tightly. “You’re going to do exactly as I say, got it?”

Arthur nodded weakly.

“Good…” John slid his hand down, putting a thumb firmly beneath Arthur’s chin and two fingers against his lips. “Now open up for me.”

Arthur let out a pathetic whimper as John forced his jaw open, slipping his index and middle finger through Arthur’s parted lips. He began to suck gently as the fingers pushed their way farther into his mouth.

“Yes… Arthur…” He purred. He slipped another finger in and reached toward the man’s throat, almost making him gag. Arthur’s restrained hand trembled against the bedframe. “God I wish I had my own cock so I could make you fucking choke on it,” John growled in his deep, guttural voice. Arthur moaned around his fingers, a jolt running down his spine at the thought of John taking him with a body of his own.

“Oh the things I would do to you, Arthur… Perhaps one day I will.” He chuckled menacingly.

As John began to pull his fingers out of Arthur’s mouth, the man bit down hard.

“Fuck!” John took a sharp (imitative) breath in.

Arthur dug his teeth into the skin of John’s fingers until a metallic taste infiltrated his mouth. He lapped at the blood with his tongue, letting it wash over his taste buds. John groaned at the sudden sharp pain. Arthur inched his head forward and bit into the more substantial meat of John’s arm just below the wrist. He tore ravenously into the flesh with his incisors, drawing as much blood out as he could.

“Christ, Arthur…” John made no attempt to draw his arm away. He simply allowed the man to dig into his skin and suck in as much blood as he could. Arthur finally let go, panting as he pulled his jaw away from the bloodied flesh.

“You’re such a fucking animal,” John said as he gently caressed the side of Arthur’s face, leaving a bright trail of blood across his light skin. Then he took hold of the man’s throat once again, squeezing just enough to leave Arthur gasping for air.

“I want everyone to know what a pathetic mess you are for me,” John growled. He let up his grip, only to begin digging his nails into the tender flesh of Arthur’s throat. He clawed his way into the skin, leaving red scratch marks in his wake. Arthur let out another whimper and John savored the reverberation of it through his hand over the man’s larynx. He ran his nails along Arthur’s chest and stomach, pausing to leave more rough indentations in the soft, vulnerable skin.

Finally he made his way back down to Arthur’s cock, tugging his pants down a bit for easier access. He began stroking it, more furiously this time. Arthur moaned under his touch.

“You’re being so good for me, Arthur.” He purred and started moving his hand even faster. Arthur’s hand pulled at the rope as his body tensed up, growing nearer to orgasm.

“Now Arthur, who owns this body?” Arthur gasped as the pressure continued to build.

“You own me, John.” His voice cracked as he spoke. He was almost over the edge now.

“That’s right, Arthur… And I’m not going to let you forget it. I’m going to use you over and over again until you’re nothing but a broken mess.”

A sharp moan escaped Arthur’s trembling lips as he came into John’s hand. He lay there panting while John basked in satisfaction.

“Go to sleep now, my friend. Lord knows you need your rest.”

Arthur closed his eyes and allowed himself to drift into a blissful slumber.

I may write more malevolent smut if I feel morbidly inspired to delve into deeper debauchery (particularly in the realms of cannibalism and wound fucking, hint hint)
