A/n Y'all really wanted the demon D 👀 But you ask and I shall deliver! I'm not used to writing lemons- in fact I don't even read much of them myself- so I apologize if it is subpar... enjoy~

~ x x x x x ~

You've been living with a demon inside your boyfriend Yuuma for about a year now. At first it was absolutely terrifying and, don't get me wrong, he still has his moments but he's not that bad.

He hasn't killed anyone else since that night which thank goodness because you don't think your heart could handle something like that again. You had convinced the demon to let the two of you continue going to school so "no one will become suspicious".

He reluctantly agreed.

Actually, the only reason you wanted to go back to school was because there was a girl there who knew a great deal about witchcraft.

You were hoping that maybe you could ask her to help you cast the demon out of Yuuma but you didn't count on her having MAJOR trust issues.

It took literally a year to get her to let you borrow one single book! You guessed she thought because you used to be such a sceptic and now knew everything was real was actually some ploy to find her secrets and make fun of her for it.

Yuuma was quietly waiting for you after school when the bell ring. You had just gotten the book, shoving it in your back, and walking out to greet him. The two of you walked hand in hand on the way.

After being possessed this Yuuma was a lot different from your Yuuma. There were of course at first physical appearances that were different such as in certain lighting his eyes were red. There was also his tongue which he demonstrated how long it was by... how you say... French kissing the back of your throat.

He doesn't really get mad but instead gets more demanding and threatening. Although he hasn't done it he's threatened to fuck you until you couldn't run away from him. You feared however that he was getting tired of waiting.

You suddenly stopped walking. This was where the two of you would split ways only if Yuuma couldn't come over which in his mind was almost never. If your mom said no he'd say "have your window unlocked then!" But this time he couldn't come because you had a book to read.

"Why did you stop?" Yuuma asked curiously.

You glanced at him. "Erm... uh you can't come over tonight." You said.

He narrowed his eyes. "Why..."

You took a deep breath. Here goes nothing. You gave him a cute smile. "Because I'm preparing a surprise for you and I can't have you spoiling it!"

His eyes widened for a moment but he looked slightly suspicious. "A... surprise?" He leaned close to your face and narrowed his eyes. "You're not just trying to get rid of me are you?"

'God have mercy' you thought. "If I did would I really do something like this?" You wrapped your arms around his neck and leaned in on your tippy toes kissing his lips passionately.

You felt Yuuma immediately tense up for a moment but slowly he closed his eyes and wrapped his arms around your waist to pull you closer. You pushed your tongue between his lips and teased his tongue with your own for a moment before pulling back with a string of saliva connecting the two of you.

Yuuma gave you a half lidded look, taking a hand off your waist and gently cupping your cheek. "You're such a good kisser when you want to be (Y/n)." He said with a smirk on his lips. "Fine. I'll let you play out your surprise but you better hope it's enough to satisfy me." He purred.

You quickly pulled away and turned away to hide your face. "Y-Yes well... I think you'll like it." You said as you slowly began to walk back home feeling his eyes follow you until he couldn't see you anymore.

You quickly made your way home and went up to your room not even bothering to greet your family. You look outside at the tree where he would climb up and go through your window at. You didn't have any blinds yet but you still closed your window so he at least wouldn't be able to hear or see you that well if he came.

You sat at your desk and opened the big dusty book. "Hope this helps." You mumbled flipping through the pages. There were so many things about summoning demons. Demon rituals, demon castings, different types of demons, etc.

You shivered. This book was downright dangerous! If your boyfriend wasn't living breathing proof you'd think this stuff was mad. Now you were surely paying the price for ever doubting the existence of Hell's inhabitants.

~ x x x x x ~

Yuuma was so bored without you! There was nothing for him to do. He didn't care about anything this world had to offer except you. What where you even doing that he couldn't be there for?

And that kiss.

That sloppy juice wet kiss was just enough to make him want to take you right then and there. You've never kissed him without him having to threaten you before! It was so nice... that's it!!

He sat up.

He couldn't take this anymore he was going to see you right now.

~ x x x x x ~

After what seemed like hours you finally found a spell that would cast this demon out of your boyfriends body! You glared at the words. The incantation was all in Latin. You struggled with pronouncing half the worlds in your own language so how were you supposed to memorize this??

You didn't notice Yuuma sitting in the tree watching you with curious eyes. What were you doing? You looked so focused on what you were reading. Was it for school? No... you've never really cared that much about homework.

"A...abi in- ....in mala...malam cur...crucem? No that's not right-!" You muttered.

Yuumas eyes widened as he felt a spitting headache. He clutched his head in pain and let out a light groan. That was some weak attempt at an exorcism spell!!! It was read so poorly though so it just gave the male a headache!

Slowly the male recovered from the pain and glared daggers at you. "You traitor..." he growled. He was going to make you pay... he was going to hurt you!! He was going to-

"Don't hurt her..."

The demons eyes widened for a moment. Yuuma- the real one- hadn't spoken directly took him like that for a while now. "But she needs to be taught a lesson! She's trying to send me back." He hissed.

"I know... what I mean is don't be violent with her."

A smirk formed on his lips. "Oh... then shall we finally collect the thing we've wanted this whole time as a punishment?"

There was a light pause. "Punish her." Was all he said.

The demon still in Yuumas body snapped his fingers making the window fly open.

You let out a yelp and toppled back in your chair. You knew immediately who it was so you quickly grabbed the book and shoved it in your drawer.

You turned to Yuuma who was just now climbing in your window. Your heart was pounding. "O-Oh Yuuma! ....didn't I tell you to stay home?" You mumbled.

Yuuma slowly closed the window and looked at you with an emotionless face. "You look like you're done with your surprise." He pouted. "Are you avoiding me?"

Your eyes widened. "No of course not!"

He narrowed his eyes and leaned close to your face. "Are you trying to cast me away then...? Like you would in an exorcism." He hissed.

Your blood ran cold. "I-I- What? N-no! What... what makes you say that?"

He glared at you for a moment before suddenly grabbing your wrists and pinning you down on the bed. You let out a yelp in surprise. You stared up and noticed his eyes glowing a red color in the lighting of only your dim lamp.

He stared down at you, slowly smirking. "Yuuma told me to do this to you." He muttered.

You stared up in confusion. "D...do what?"

He let go of one of your wrists and held it over his eyes for a moment. "I was going to beat you into submission but he suggested I use other means." He pulled his hands away and his eyes were a light shade of blue... just like normal.

"Y-Yuuma..." you whispered.

"...so if you're going to hate anyone for this... then hate him." He closed his eyes and leaned in, taking your lips with his own.

You shut your eyes tightly but didn't struggle much against his gentle grasp on your wrists. He bit your bottom lip, singling you to open your mouth but you shook your head and refused. He growled and pulled both your wrists so he could hold them in one hand. He used his other to take ahold of your face and force his thumb in your mouth. You snapped your eyes open and started struggling and thrashing around knowing what he was going to do.

He pushed his lips firmly against your own with his nails digging into the side of your mouth. His tongue slowly entered, caressing against your own. He moved it back further and further into your mouth slowly moving towards the back of your throat.

You struggled not to gag at the sensation. No way!!! You managed to rip one of your hands from his grasp and swiftly karate chopped him in the throat. His shot up and quickly he pulled back and began loudly coughing, letting go of your wrists but still sitting on top of you. He held his throat and glared down at you.

"That's it!!!" He growled, taking his belt off.

You gasped. "Y-Yuuma what are you-!?"

He flipped you over onto your stomach without warning, grabbing both your wrists and twisting them painfully behind your back. You let out a cry in pain as you began struggling and writhing under him.

"Y-Yuuma stop!! If you don't let go I'll scream and then my parents will come!!!" You threatened.

He tugged at the binding making sure it was tight enough. "If you call them we'll just have to deal with a lot more blood in this secession."

You felt your heart stop. He didn't mean he would... he... he'd kill your parents?

~Lemon~

Yuuma flipped you back around and tilted his head, seeing your shocked and horrified face. He leaned in and whispered in your ear "(Y/n)... just remember who's body you're being fucked by~." He cooed.

You felt a blush quickly creep up on your face. You quickly shook your head. No! You wouldn't let yourself submit.

Yuuma pulled his face away and gently kissed your lips in a soft manner. He pulled your shirt up past your bra and grabbed your bare sides with his cold hands. He moved away from your lips and went down to your stomach. Your eyes followed his movements with a pounding heart.

He stared down at your stomach and gently started giving you light butterfly kisses. You felt your blush creep back on your face. It was a strange thing to feel his soft plump lips press so delicately against your (s/t) tummy.

He moved his hands up and slid your bra up revealing your chest. He sat up and smirked as you gasped.

"Y-Yuuma wait-!"

He moved one of his hands and gently grabbed on of your breasts. You couldn't help but arch your back and bite your lip at that movement.

"You can't be too loud okay (Y/n)? Everyone's asleep and they don't deserve to hear your pretty noises." He teased, moving his lips down to your left breast and taking the nipple in his mouth.

You quickly pressed your lips together to hold in a soft moan that almost escaped your lips. He poked his tongue out sucked gently using his other to stroke your breast. He noticed you were struggling to hold back a moan so he took your nipple in his hand and gently squeezed and rocked it between his fingers.

Your mouth opened up and released a gentle moan that slipped out of your lips. Your faced turned a darker shade of red but you couldn't stop from making noise and wiggling underneath his touch.

He pulled his lips away from your nipple leaving a string of saliva. You panted in anticipation.

He chuckled. "Should I gag you? I haven't done much and you're already getting loud..." he moved between your legs and slowly slipped your shorts off, tossing them over somewhere else.

You tensed up. "W-Wait! Wait... d-don't!" You quickly said with worry in your eyes.

Yuuma tilted his head. "You mean... you don't want me to do this?" He moved his hand down between your legs and pressed his fingers against your clothed entrance. A jolt of electricity seemed to course through your body as it very slightly pushed forward making you let out a gentle whimper. "Because it looks like you do~."

He gently started rubbing circles and pressing in more just enough for you to barely bite back a moan. The tease was absolutely killing you...

He moved his fingers to the side of your undergarments and slid them down past your ankles and off, throwing them over to where your shorts where.

"Look me in the eyes (Y/n)..." he said.

You hesitantly shifted your eyes to look down at him and stare into his blue eyes. It was so erotic to see him between slowly lowering himself between your legs. He smiled at you. "You'll like what my tongue can do to you." He muttered, looking away from your eyes and slowly enveloping your womanhood with his mouth.

"Mm- a-ah~!" You couldn't help but moan out softly, your hips bucking forward. Yuuma took his hands and pushed your legs open more. His tongue poked out and trailed circles around the edges of your clit. Your breathing became more intense as you tugged against the bindings of the belt on your wrists, shuddering at the unfamiliar feeling.

He kissed and caressed you pressing his tongue slightly in before taking it back out again. It was enough to make you groan and arch your back further against his lips.

He kept teasing you but poking his tongue in only to take it out. It never went in far enough.

"Y-Yuuma please~!" You couldn't help but beg. Hearing his name seemed to turn him on more. He let out a chuckle making his lips vibrate against you. You clenched your teeth.

He opened his mouth wide and pressed it up against your now dripping wet womanhood. He pushed his tongue further and further your caverns. You bucked your hips coward and opened your eyes, panting at the sight of him.

He swirled his tongue around and stuck it in and out and deeper and deeper. He sucked up your juices as they seeped out. You moaned uncontrollably. His tongue teased a spot that was just right. You threw your head back against the pillow, moving your back higher.

"Y-yes! There!!" You moaned. He obliged to your plea and stroked his tongue against that spot. A knot that felt as if it were tied in your stomach suddenly released making you jolt in absolute pleasure as you came into Yuumas mouth.

He lapped it up and raised back up with drool and you assumed other substances dripping from the side of his mouth. He stuck his tongue to the corner of his lips and licked it up. "You're becoming too loud (Y/n)... you might wake someone up if you keep that up."

You couldn't help but blush madly at this but at the same time you didn't care. It just felt so damn good...

He moved you over back into your stomach and gently massaged your sides. He took his shirt off and moved it up to your mouth. "Bite down on this so you're not so loud~." He purred.

You obliged and took the shirt in your mouth. You felt his hands rub around your hips and down to your thighs. He slowly took his own clothes off, you could hear him panting.

"I've been waiting so long for this~." He purred. He pulled your hips up so you were on your knees with your face pressed down into the mattress, the scent of his shirt filling your nose.

You felt him poke your entrance. "Don't tease me Yuuma!" You muttered in with your voice muffled from between your teeth.

He let out a light giggle. "Oh (Y/n)..." his hand trailed dangerously near your entrance making you jolt. "I'll be sure to go rough on you." He grabbed your hips and slowly pushed himself in.

You let out a gasp in pain. "T-That hurts!!" You cried.

He pulled out then slowly pushed back in. "You'll get used to the pain..." he whispered. He couldn't help but shiver at the feeling of being inside you. He continued at a slow past to thrust in and out of you. You felt the pain slowly turn into pure ecstasy as erotic noises escaped your lips but muffled with the sheets.

Yuuma gripped your hips tightly and thrusted right into your sweet spot. "(Y-Y/n)~." He moaned your name. You managed to bob your hips with his pace as he got faster and rougher with you. Your nails dug into your palms, your teeth digging into his shirt.

"H-Harder~!!" You moaned. With that he started grinding against your harder with a visible sound. You could hear him grunting and letting a moan out here and there... it was so hot.

You felt yourself have another orgasm and as soon as you did you felt Yuumas hot seed release inside of you with a husky sounding moan.

He slowly pulled out while panting. He flipped you back over on your back and stared down at your blushing red face. He took his shirt from you mouth and swooped down to your lips, pushing his tongue in with a messy heated kiss. He pulled back and smirked.

"I hope you're ready (Y/n)... because I'm not done with you yet."

You gave him a confused and exhausted look. "What do you-?"

~ x x x x x ~

You angrily held ice to private parts with a mildly pissed off look on your face. Oh he fucked you... he fucked you real good. But god damn it hurt. Your limbs where incredibly sour, your voice was horse, and you couldn't stand up. All you wore was some shorts and a loose shirt with no underwear. It hurt too much!

You had bitemarks and hickeys in several places. Not very many were on places you'd expect like your neck... but they were rather much lower.

Yuuma was lying next to you gently cooing in your ear in a passive aggressive way. "If I ever find you trying to cast me away again..." he narrowed his eyes. "I'll fucking break every single bone in your entire body~."

You shivered. You honestly didn't think you had the heart to send him away after something like that.
