Demonic Tension

Fumikage Tokoyami walked through the front door of his house. His specially made shoes came off, revealing scaled yellow like feet with small sharp claws on the end. The raven boy sighed in relief as he took them off, stepping through the small entrance way to the hallway. Tokoyami ran a clawed hand through his spiky, jet-black "hair" feathers as he relished in the end of the school day. Even the best grew weary of all the training they had to do to become heroes. Heading up the stairs, Tokoyami entered his bedroom and sat at his computer desk. Taking his bag and pulling out his work, he began his studious needs.

Time ticked by as his pencil scrawled along the papers. He used his computer to help him as needed, though he did try to learn from textbook and memory before going to that. It was with a heavy sigh he put his work to the side and leaned back in his chair. When he closed his eyes for a moment, his hands went up to the tie of his shirt and took it off. Tokoyami debated undressing further but decided against it for the time being as he stood to go downstairs and make dinner.

The young bird decided on making a simple meal of curry. As he began preparations, he decided to call upon his quirk, Dark Shadow. It was as it seemed, a shadow made of purple and black in a shifting state. It's prominent features was a beaked face with yellow eyes, head similar to Tokoyami's, and two arms with claws at the end of the fingers. They were physically linked as the shadow came out of Tokoyami's back.

"You called for me?"

"Would you mind starting on the vegetables for me? I'll share some curry with you when it's finished."

Tokoyami could feel the excitement of Dark Shadow as he went over and started right on chopping the vegetables. It was strange, how Dark Shadow was a part of him yet felt like a completely separate person at times. The young bird grinned to himself as he continued cooking, taking time to thank Dark Shadow as well. Soon the plate was set and leftovers were in the fridge. The two dug in, Dark Shadow only partaking in a small portion to allow Tokoyami to consume it for energy. When the plate was emptied, the young bird went about cleaning the kitchen up. Dark Shadow mostly just watched, hovering over Tokoyami's shoulder.

When all was said and done, Dark Shadow spoke up. "You seem tense tonight."

The bird sighed as he nodded, rubbing at his eye. "Very. It's time for a bath I think."

"Perhaps you should find a way to alleviate tension?"

That drew a pause from Tokoyami, his cheeks reddening a little. Being of adolescent age drew a lewd idea to mind that he shook out. He couldn't help but agree though. "Perhaps you're right. Maybe I'll look up some things to help after the bath."

The trek to the bathroom was quick. Sighing as he shut the door, Tokoyami began to undress himself. With his shirt off, the young bird looked at his torso, lightly running a hand over his athletic form. He needed to be fit for this sort of job. Though letting a finger run over his pink nipple was a tad much as he let out a sigh. Unbuckling his pants, they flopped to the floor. Standing in naught but his boxer briefs, Tokoyami started up the bath water. Once the water was filled, the bird shuffled out of his underwear and slipped into the bath. He sighed as he sank into the warm waters, leaning back along the rim.

Soaking in the water, he had a strange idea. Calling forth Dark Shadow, he spoke. "Dark Shadow, do you think you can help me with my tension tonight?"

"Of course, Tokoyami."

Dark Shadow's claws began to knead at Tokoyami's shoulders, making the young bird sigh in relief. It felt good to relax, let his mind wonder. It first turned to school and his classmates. While he tried to be friends with them, they were still rivals. And the classes were intense to say the least, even without the villain incidents. The claws lowered down to stroke over his chest and Tokoyami sighed out more. Thoughts drifted to his absent parents. His mother was away on a business trip while his father had to contend with family. Left home alone, the house was strangely quiet. Next came himself, how he was still skinnier than some of the others because he used Dark Shadow more than he should. His mind came back to the present as he felt the claws rake through his gray pubic feathers before he tensed with wide eyes from the grope to his genitals.

A gasp came as Dark Shadow started to rub vigorously at his sensitive parts, blood rushing to his face and groin. As his cock rose to the occasion, Tokoyami felt the coldness of the shadow claws graze over his nipple before circling it. A groan came from the young bird before his gaze came back to his arousal, the cold hand grabbing at his shaft and pulling down the black skin surrounding his bulbous pink cock head. The claw tugged back up before sliding down again. Another few times and a groan, Tokoyami felt heated with Dark Shadow hovering next to him. It was with the thought of his quirk that brought the bird back.

"S-stop!"

Instantly, Dark Shadow released his hold on his master. Tokoyami tried to cover himself as he breathed harder. The need seemed real enough but he still tried to berate the quirk. "What do you think you're doing?!"

"As you asked. You always are relaxed after doing that."

The bird grumbled lightly as he thought about it. He never truly had privacy in anything. Not that it wasn't something he'd thought of asking of Dark Shadow before but he wouldn't say it outright regardless. It was wrong. Sighing, he decided that while he was aroused he'd at least clean his dick. "That's more of a private thing Dark Shadow."

"..."

Dark Shadow retreated after that, allowing Tokoyami to finish his bath in peace. A flush remained anyways as he tried to not let the feeling of another on his body run rampant. Dark Shadow was technically his own person but it was a part of the bird. It was confusing to say the least. Standing, Tokoyami unplugged the bath and proceeded to dry himself as the water was sucked down the drain. He wrapped the towel about his waist as he got out, leaving to head towards his room. At this point, darkness was the only visible thing. The bird swallowed a lump in his throat. In the light, Dark Shadow was more meek and docile. In the darkness, however, he became unruly like the demonic entity he seemed. Shaking himself, Tokoyami pushed forward into the darkness to his bedroom not far away.

It was completely dark in the hallway and Tokoyami could feel a strange sensation as Dark Shadow came out, speaking in low murmurs to let him take control. Shivering, the bird tried to keep calm as he went into the bedroom. Strong moonlight shone in from the window. About to flick on the lights, Tokoyami let out an oof as he was pushed from behind, landing on his hands and knees. Dark intentions crawled at the edges of his mind as he turned about, on his back now. His gaze was captured by Dark Shadows, the beast before him holding the towel in a hand and the bird realizing he was naked now. Fear started to spread into Tokoyami's frame, making him tense up.

A wicked grin grew over Dark Shadow's beaked visage. A shadowy hand trailed along the beak before lowering to something that caught Tokoyami's attention. Dark Shadow had a body, fully. As far as the young bird knew, the quirk had never had one. Regardless, the claw circled a light patch on the torso. A low rumble came as the demon's eyes lidded, a dark hunger in them. To Tokoyami, it seemed like Dark Shadow had an adult version of himself, but his mind was still on alert to the dangerous creature above him. When Dark Shadow came down, the bird thought it was going to take over, but instead gasped out as something slimy and warm ran along his neck. A shiver ran down the Tokoyami's spine as he realized a tongue had run over the feathers.

"D-Dark Shadow! What are you doing?!" His voice was shaking.

"As master asked of me."

Dark Shadow let a claw slid over the pink nub of the bird's nipple as Tokoyami let out a soft groan of want. It was weird, this demonic quirk of his could easily overtake him right now but was instead following an order from earlier? It seemed like he had a long way to go before understanding Dark Shadow better. His mind was distracted when the free claw of his quirk moved to fondle at his black balls, the cool touch strange on his heating body. Tokoyami grew aroused, his cock stiffening up under his quirk's new-found body. The tongue worked up to his beak, the bird breathing harder before Dark Shadow shoved the appendage down the bird's throat. Tokoyami choked on it, eyes wide as tears sprang to his eyes while the tongue explored deep. When it came out, the bird turned his head to cough and heave for air, spittle dripping out.

At that moment, Dark Shadow struck. The clawed hands pinned Tokoyami to the floor by the arms, a sadistic grin plastered on the demon's beak. The bird tensed up, gasping as he felt something long and hard brush along his arousal. Looking down, Tokoyami's breath hitched at the sight of Dark Shadow's genitals. The cock was similar to his own, though bigger in girth and length with a massive patch of lighter color crowned the base of the shaft to resemble Tokoyami's own pubes. A drop of pure blackness formed on the cock tip, leaking down and dripping onto the bird's feathers.

"I know what you watch when you use the privacy part of your browser."

A shiver ran down the bird's spine as Dark Shadow started up a slow pace back and forth along his shaft. Of course Dark Shadow was privy to all of Tokoyami's interests. A groan came from Tokoyami, the foreskin bunching up and being pulled back by the stronger demon above him. What he looked up was other males doing naughty things, for when he desired help with his fun. The bird hissed as the cool pre of Dark Shadow contacted his skin, heating up as it aided to lessen the friction. Tokoyami was ashamed to admit that he had thought of different guys he thought were attractive, even sometimes imagining asking for Dark Shadow's help.

A loss of contact made the bird open his shut eyes, pondering why he felt Dark Shadow's cock grazing over his balls. They went wide again as it slid between his rump cheeks to press again his virgin tailhole. Dark Shadow's smile was one of horror to Tokoyami.

"I know you want this. You have practiced."

The bird had used one or two fingers back there, sure, but this was a whole other level. He struggled against his quirk's grip, already knowing it was futile. He was to be ravaged this night by his own inner demon. Tokoyami didn't have time to dwell on it as he felt pressure against his entrance. He could not deny the demon invading him, even with how tense he was. A cry came from the yellow beak when Dark Shadow slid into his ass. Strong feelings of pain emanated from the forced entry, feeling like he was being split in two, yet Dark Shadow paused. A strange feeling of numbness started to spread from the point of entry. Tokoyami was unsure of what to make of this but felt as Dark Shadow pushed further and further in. The pain was there, just dulled, and now he felt filled. The cool feeling of the quirk's balls against his rump signaled Dark Shadow's hilting. Again, the demon paused as the tongue wound around the bird's neck, slurping loudly.

"Now the fun begins."

Dark Shadow pulled from hilt to tip in a fluid motion. The sudden change from full to empty was startling to Tokoyami. The feeling was short lived as the thrust back in elicited a cry from the bird. The jolt of pleasure was new and unusual, repeated as Dark Shadow continued to pump in and out. The flagging arousal Tokoyami had started to come back, heightened by the beak nipping and licking along the bird's neck. Gasps of air came from Tokoyami as Dark Shadow used him.

It only took a little while before Dark Shadow shifted a bit and drove in harder and faster, seeming to want more. Or maybe Tokoyami was impressing his own thoughts onto the demon. The bird wasn't sure now as he understood how good it felt with balls slapping his ass, breath on his neck and a body above him, thick meat wrapped snuggly in his tight confines. It was strange how colder Dark Shadow was, but that was something he was getting use to and enjoying considering he was always warm due to his feathers. Every thrust jolted Tokoyami, who was clawing at the floors with his claws as he heaved for breath.

Again, Dark Shadow adjusted his angle of entry, only this time when he shoved back in, Tokoyami let out a loud cry. His body tingled with electricity and pre leaked from his tip. The bird wasn't much of a pre-maker, so this was something interesting. Cool air brushed along his neck, coming faster than before. It seemed like Dark Shadow was nearing his limit like Tokoyami was. A handsfree orgasm was something the bird never thought he'd actually experience but it seemed to be approaching if his bunching balls were any indication. Tokoyami didn't think Dark Shadow could sweat, but he definitely was by how heated it had become in the room as slurps and smacks echoed. Dark Shadow's thrusts grew erratic, going wild on the bird's rump as they reached the end.

Dark Shadow hilted and let out a guttural roaring cry. Tokoyami felt every inch of the demon's shaft throb in his rump before jets of cool seed flooded him. It was too much for the bird, who cried out and arched as he blew his own load. Stars filled his vision as his mind blanked out for a moment, teeth clenched. Coming down slightly from cloud nine, the bird looked over his body to see a swelling in his belly some as well as growing conscious of the seed splattered on his beak and hair. Dark Shadow gazed sleepily down at Tokoyami before pulling out. The bird gasped and felt a back flow rush from his abused rump. The inner demon, it's deed done, withdrew back into Tokoyami to rest from the experience. A small voice in his head spoke.

"Your relaxed now."

A shiver ran through Tokoyami. All of this because he asked his quirk to help with his tension. Reaching down, the bird smeared his hand in the seed from his ass and brought it up to see. It was black as night. Curious, he licked some from his fingers. It was cool, as expected, and tasted gross. Yet he felt like he wanted more. Sighing though, the tired bird stood and grabbed the towel that was discarded. The mess made needed cleaning and Dark Shadow was already slumbering for the time being. Himself and parts of the floor were wiped up and the towel discarded in a corner. Tokoyami was too tired to think of taking it to the rest room.

Pulling the chain to his lamp, the bird flopped onto his bed. His mind started to ponder things. He had to wonder if this actually counted as sex or just an extreme form of masturbation. While Dark Shadow was an intelligent being, he was still Tokoyami's quirk and therefore a part of him. It didn't really matter he supposed, since he'd likely ask for Dark Shadow's help again, whether it be this strange new bodily form or the usual. Closing his eyes, Tokoyami let sleep overtake him, feeling himself relax even more.
