This story is dedicated to MommaSuga  early birthday present tho.

That moment when you two first made eye contact was when the living hell began. Just like a wolf in sheep's clothing, he was a devil disguised as an angel. A very beautiful angel. An angel that would sin and fall from heaven just to experience the ecstasy from feeling your skin against his skin.

The first day made you tense up since you felt something, unsettling. Some sort of strange aura was emanating from behind. Finally mustering up the courage to look, you made eye contact. Only three seconds of that contact and you felt like a target. Those eyes bored deep into your head. You could've sworn you saw an inferno ignite within those glowing orbs. An inferno of a sudden sinful desire to lust after you.

Trying to not think much about it, you resumed your daily school activities. Only having a quick glance of that inferno seemed to have distracted you from your thoughts. Finding yourself zoning out more often, it became apparent that you may have an attraction to him as well.

The night of the first day was quite a sinful one for Sugawara. He laid in bed staring at his ceiling trying to control the sudden urge down below. All he could imagine is what you would look like right below him covered in bite marks. Lips flush from the rough kisses, and- no he stopped himself there in fear he might let the devil out too soon.

The second day was like a game of hide and seek. Standing in the library sifting through stacks of books for a class project, you could've sworn you spotted him staring at you. When you spun your head around, he wasn't there. Tension was building up inside your spine as you began to hunch over even more. You tried to make yourself look as invisible as possible.

"Is this the book you're looking for?" his sweet voice startled you from behind.

In his grasp was the exact book you were searching for. The grip on it seemed rather tight since his knuckles were ghost white. He was also holding it rather closely to his body. Avoiding any awkward contact, you grabbed the corner of the book. Being careful not to touch his body, you slipped it out from his hands without a struggle.

Steering away from him immediately, you briskly walked out of the library. Your heart was pounding at your ribcage and so was Sugawara's.

The third day was a rather strange one. You were staying after school to work on your project when your teacher came up to you. She had something in her hands that looked like some sort of paperwork.

"Could you deliver this to Sugawara in the gym please? I'm in a hurry to get home, and I'm not sure I'll be able to get this to him on time."

You gulped and shakily took the paperwork from her. She hurried off almost bumping into another teacher. Your throat was dry now. How could you face him when you always got flustered around him? Your sweaty palms were already leaving handprints on the paperwork. Worryingly rushing off the gym, your heart was pounding against the ribcage. Each beat sent a vibrating shock through your ever terrified form. You were about to reach for the door that leads outside to the gym, but it opened. It was Sugawara.

"Oh..." he whispered softly letting the door clang shut behind him.

There was an eery and awkward silence between you two.

"T-this paperwork, it's for y-you," you stammered not looking him in the eye.

Good thing the sweaty handprint marks were gone. The shaking in your hands was clearly visible for him to see. In the split seconds that he was reaching out, dark fantasies were clouding his mind. Imagining how beautiful you would look with your wrists tied behind your back, his hand moved right over your right wrist.

"Sorry!" he piped up snapping back to his fake angelic self.

"N-no you're fine!" you bowed and scampered off back to your classroom. Your heart almost leapt from your throat then.

Sugawara let his mind darken once more. The faint smoothness of your skin was still lingering on his hand. Glancing behind him, he moved his hand towards his mouth. He let his tongue dance all over his palm leaving a slick trail. Tasting all that he could, he enveloped his fingers suckling on them. A lewd moan strained from his mouth as a result. He sulked back to the gym since he was only taking a "break" just to see you.

The morning of the fourth day started out surprising for Sugawara. Waking up from a rather suggestive dream involving up, he noticed that something was stirring down below. Trying to recollect himself, he arrived at school an hour later than usual. Of course when he briskly walked through the doors, it was passing period. Desperate to see you, he wandered the hallways instead of heading straight to class. After confirming that you were "safe" in your classroom, he sprinted back to his class in the nick of time. Half of the day Sugawara spent attempting to forget the suggestive dream of you.

The paperwork you handed him yesterday was for college, so he stayed in his small corner during lunch to fill it out. He was too occupied last night staring at his hand that he "accidentally" touched you with. Still watching you carefully out of the corner of his eye, he was angered on the inside of the sight of you having a conversation with Daichi. From his point of view, it seemed like you were flirting with Daichi. In reality, you two were conversing about volleyball.

"Get away from her."

That sinister voice muttered inside of his head. Devil horns were already beginning to break through his forehead. The halo was melting off his head. His angel wings were wilting with black feathers replacing the white ones. Innocence was chipped away by the darker desires in his heart. The devil inside was gnawing and scratching at its cage loosening the rusty lock. Something was holding him back, the light that keeps him from rotting away into nothing.

The rest of the day involved you being more closely observed by Sugawara.

"Mine. Mine. Mine."

Days five and six took place over the weekend. This meant that Sugawara wouldn't be able to see you at all. He did know where you lived, but this devil was too smart to start stalking you now. Locking himself in his room most of the time, he kept whispering to the walls around him. Dragging his fingers in intricate patterns along the wall as if you were there, the familiar stirring down below occurred again. The sudden disturbance made him dig his fingernails into the wall peeling off some paint.

They weren't some random claw marks, he etched out "MINE" in the drywall.

"All mine."

The night of the sixth day was a major change for Sugawara. Now intoxicated by his own pleasure, the lock caging the devil finally loosened enough. Mind clouded by the thought that you were his and only his, he vowed to himself that you would belong to him. Whatever means he would have to use, you would be his in the end.

Carefully planning out what he was going to do tomorrow, he stayed up all night. The stress from staying up combined with the devil inching out of its cage brought forth a new him. The angel was non-existent. Devils horns now replaced the melted halo above his head. Black angel wings represented his true nature. A devil crow that will soar through the night in search of you.

The sun rose on the seventh day. As the light peaked through the curtains, Sugawara cracked a mad smile across his paled face. He was fully insane with the strong intent to make you his. All night long, he planned out how he was going to execute his sinister plan. Only problem he encountered was to lure you in alone.

The entirety of the last day went as planned, normal. The devil was still wearing the discarded remains of the angel. With each passing minute, this crude disguise was rotting away. Soon the time would come for him to tear the friendly mask off in disgust. Impatiently fidgeting in his desk the whole day, he worried he would draw unwanted attention. Who was there to even stop him? Daichi was touring a local college, so he timed this correctly.

Now becoming more and more impatient, the last few minutes of the school day rocked by on the clock. You were scheduled to help organize the library catalogue today. The catalogue was tucked away in a small office in the far corner of the library. Perfect for cornering and trapping you. Of course he only found this out after sneaking some of your school files.

Carefully pacing himself to not appear suspicious, he snuck into the library that was locked to help you organize. Stealing a set of master-keys in advance, he gently unlocked the door. Not making a sound, the door softly clicked shut. Frustrated sighs were faintly heard from the back office. Now locking the door behind him, he snuck around for a light switch. A devil always works best in the darkness after all.

"What the hell..." you grumbled with the disappearance of light.

It was probably Nishinoya or Tanaka playing a prank on you once again. Sliding your fingers along the cramped office walls, you found the light switch. To no avail, the lightbulb was burnt out. Of course it would be burnt out, no one works in this office.

"Okay very funny, but you aren't supposed to be in the library..." you trailed off realizing that the doors are always locked. They could never get their hands on the keys.

It couldn't have been the janitor, they don't clean the library until after you leave. Someone else was in here, and it's not staff from the school. Wandering back to the small office to grab your phone, you almost tripped over a few books. There were just books, randomly lying out in the middle of the floor. Straining your back to bend over, the faint light from outside illuminated the covers. All books had the word "devil" on them.

Something squeaked from the office and you raised your alert instantly. Ignoring the books on the floor, you began inching backwards towards the door. When your back hit a warm body, you were about to scream. Hands flung around your eyes and mouth. Erratic movements dragged you somewhere. Your frightened cries were muffled by the iron grip of the hands on you. Practically being tossed into the small office, the door slammed shut engulfing everything in darkness. Darkness perfectly suited for a devil to see.

"S-Sugawara..." instantly recognizing the softness of his skin from when his hand brushed over yours before, you meshed your body against the wall.

A hand somehow traced the features of your cheek down to your jawline. Cautiously leaning into his gentle touch, your hand reached up and pressed his hand firmer to your skin.

"I'm surprised you aren't screaming your lungs out by now," he put emphasis on "screamed" as you felt his body cage yours in.

It appeared from when he blinded you with his hands, something triggered you to not resist at all. Could it be that Sugawara's plan was working out as planned?

"All mine," he muttered tracing the pad of his thumb over your lips.

On the outside you were terrified and ready to thrash away from him, but on the inside, you were intoxicated by, something else. Intoxicated by his longing touch to be exact.

"Yes," you whispered softly into his ear, "I'm all yours."

He had you wrapped around his finger now.

"I still have to punish you for being so close to," he paused huffing out a frustrated sigh, "Daichi," disgustingly growling his voice out, one hand cupped your left cheek while the other wrapped around your right hip.

"Suga..." sighing out his nickname, he hushed you.

"It's Koushi."

Letting his first name leave your lips, there was an instant warmth around them. His lips were wrapped tightly around yours. Easing out his frustration, he tilted his head to the right. The hold on your hip stiffened as he deepened the kiss. Not even asking for permission, his tongue forced itself through your slightly parted lips. This new sensation sent a shiver down your spine. Your arms were limply around his neck with hands beginning to slide through his hair. Needing air desperately, you gradually pulled away. His lips were back on yours immediately afterwards.

"Koushi..." his name came from the back of your throat as more of a groan than a sigh. This gave him the sign to start exploring.

Fingers clenching into his hair even more now, you lavished the hot, wet kisses he left down your jaw onto your neck. Nipping ever so carefully at your sensitive spots, you began to squirm underneath him. Hands started to roam your body; the hand on your hip inched towards your backside, and the one on your cheek dragged your shirt over your shoulder. Scrapping his teeth over the exposed skin, he sank into your skin. The sudden sting made you audibly gasp from pain and confused pleasure as your grip on his hair bound tighter. Massaging the bite wound with his tongue, the sudden squeeze of his hand on your backside made you squirm more. Desperate for his mouth, you jerked his head back up to yours by his hair. Your sudden roughness awakened the devil's urge. Slamming his lips back onto yours, both hands were on your backside kneading it roughly. Now beginning to roll his hips against yours, several moans bubbled out of your mouth.

"More," craning your neck, he attacked it hungrily leaving bite marks and hickies in his wake.

"(Name), you're so fucking beautiful. I can't hold myself back anymore," his soft tone was replaced by some strained animalistic one.

Before you could react, he spun you around so your back was to him and not the wall anymore. It's not like it mattered, all you saw was darkness anyways. Hands still roaming your body, he effectively ground his hips roughly into yours. The wall groaned with each snap of his hips. Sugawara was holding back for some unknown reason. He obviously had your consent since you weren't protesting, so he could just take whatever he wanted. Something inside himself was holding him back. It was the last feather of an angel wing. The last of the light that Sugawara had left. Without it, he would've already had turned you into a begging mess beneath him.

"More," those words rang more in his head, so he happily complied by slipping his hands under your shirt in the front.

When the tips of his fingers ghosted around the warm metal of the bra's underwire, he seized his actions completely. Left in a haze of confused pleasure, you didn't utter a word. It seemed like he was contemplating with his decisions. Gently spinning you back around, he left a lingering kiss to your forehead. Without another word, he left the office. Trying to process the situation, you only watched as he vanished through the back exit of the library. Something flew out of his pocket as the door shut. Staggering out into the dark library, you leaned down to see what it was. Carefully plucking up the object from the floor, it felt soft in your fingertips.

It was a crow feather.
