Disturbia (Yandere!Beel x reader)

No mistake

Beel had just finished a set of pull-ups. he dropped from the bar on his ceiling, and wiped sweat off his chest. 

he was furious. oh it was taking every trick that the human had taught him to stop his rage from boiling over. 

that cut on her chee was fresh. he had heard about a patient attacking their therapist earlier. but he never thought it would be her.

he scratched the back of his head. 

the patient had been taken to the medical ward because the guards had to sedate him. 

but Beel couldnt let it slid. no, he would never let anyone who hurt her be forgiven. 

he cracked his knuckles. the medical ward was easy to get into. and it was mostly nurses and patients with minimal guards. he would kill him easily. 

he shut his eyes, trying to dim his anger. 

was she scared? did she cry? how badly did it hurt? how badly did it bleed? 

he tugged on his hair. he could only imagine how upset she was. his Miss L/n. his Y/n. his beautiful little human. her smile made his heart race and his pants tighten, her smell drove him insane. it was so sweet, so lovely. he could smell her when she got in his hallway, it always drove him mad. 

his leg jumped up and down as he remembered their talk today. the look on her face when she saw the necklace he had made. it was pure joy. she looked like a puppy sometimes. so perky and excited whenever he did something right. he made mistakes just so she would praise him. so she would have that proud look in her eye. it made his knees weak. 

he shouldnt. he shouldnt think these things about her. he refused to tell her about those sexual thoughts because they always involved her. his sweet Y/n. tied up on his bed, tears running down her face. begging him. bloody bite marks all over her soft squishy thighs and tummy. he wondered if her blood tasted sweet to? she would be whining his name, moaning for him to take her. breed her. 

he covered his face with his hands. he hated himself for it. beel knew how rude it was to think of such a kind women like this. but she wore such short skirts and tight clothing, low cut tops that showed him peeks of her very ample chest. maybe... maybe that was her way of telling him. it had to be. the way she always touched him, she had to know what she did to him. how crazy she made him feel. 

beel shook his head. as if he could physically shake out the mental pictures of her in thigh highs and a short skirt. 

he had a job to do tonight. he couldnt make a mistake. 

he stood up, and went to the toilet in his room. he groaned audibly, as loud as he could and hit the wall.

he took a deep breath, and pushed two fingers into his mouth, making him wretch and gag loudly. 

from outside he could hear a guard knocking on the door to check on him. 

"Beelzebub? are you alright?"

he did it once more, groaning and hitting the wall. it wasnt pleasant, but hed do anything to get revenge for his human. 

the locks on the door clicked, and three guards came inside. 

"food poisoning." one of them muttered. 

Beel gagged again, before the three men hoisted him to his feet.

"come on, lets get you to the Medbay big dude." one said. 

the walk was short, and soon Beel was sitting on the edge of a bed, a bucked hugged to his chest while the old nurse checked his vitals and brought up some medicine. 

"with the amount you eat you were bound to be brought here at some point." the nurse muttered. 

he only groaned, wretching again. 

three beds down was the only other patient in the Medbay. 

he just needed the nurse to be gone long enough for him to kill that bastard. but what could he do?

he glanced around, a bottle of sanitizing solution without a lid, andsome of his medicines sat on a tray between him and the nurse.

he was close to it. but was he close enough. one good bump and it would all be knocked over, right onto the nurse. 

he lurched forward, acting as if a particular strong dry heave had overcome his body, and knocked right into the tray. it jerked back, the sanitizing solution, and medicine promplty falling, spilling all down the front of the nurses scrubs. 

"i-im so sorr-"

he dry heaved as the nurse cursed quietly. 

"just-just stay right here boy, damn residents leaving lids off o..."

her voice faded quickly as she went to go change and get his medicine. 

Beel put down the bucket, and got out of his bed, he moved the curtain back, and stalked over to the demons bed. he was barely councious but thats all beel needed. 

he looked around, finding a pair of scissors that he could use, and put them in one of the patients hands. carefully, and quietly, he aimed the wicked sharp blade at the demons forearm, and cleanly slice down, opening a large vein. he barely stirred as beel continued, carving deeply into his arm. blood quickly spread over the covers, barely missing Beel as he worked. 

releif, and excitement were filling him. but he reigned it all in quickly. he wiped off the hand, and then the scissors to make sure only the other demons prints were on them. he checked his body for any blood, and snuck back to his bed, wretching and groaning. 

he felt good. his anger had subsided. and he felt almost proud of himself. he had kept Y/n from having to meet with this monster again, he had kept her from possibly getting hurt tomorrow. it felt good. it felt right. 

when he got out he knew he had to stay close to her. he had to feel like this again. calm, proud. he had kept her safe, thank diavolo she was safe. he had to keep protecting her. by any means neccessary.
