Work Text:
"I'll pass tonight!"
You waved off to your coworkers who were inviting you out to drink again. But tomorrow you needed to get up early to run some errands since you had zero time during the week.
Sighing as you began your trek back home and looked down the road toward the setting sun. You had taken five steps when suddenly the concrete under your feet began to glow in an eerie circle, enveloping the entirety of your body and your surroundings disappeared from view.
—--------------------------------------------------------------
"Why the fuck am I here!?"
"Well uhh…the local priests are worried about your lineage-"
A book was thrown at the green haired assistant.
"HAH!? Then is -that- what I fucking think it is!?" he pointed to the large rune circle in the middle of the room.
The assistant laughed nervously, "Yes?"
Bakugo stomped over to him as he spoke, "I. ZU. KU. !!!!!"
"Kaachan! I had nothing to do with it! It's- "
The two both turned their heads as a bright flash illuminated the area and crackling in the air sounded as something or someone began to appear.
"Fuck! Now I have to send whatever it is back."
"Uhh…about that. They somehow got your blood and..already contracted it to you.."
Izuku could see the veins popping out of the blonde's face, ready to burst from his anger.
Bakugo grit his teeth, "Tell those fucking priests I'll have their heads. I'll take care of this."
Izuku bowed before running off.
—--------------------------------------------------------------
You kept your eyes closed for what felt like forever until the blinding light dimmed. Your hands reached up to rub your face, blinking a few times before your vision cleared and were able to see.
Except, you were definitely not on a sidewalk heading home. You peered around the room you were in, noticing it looked more like a mansion. The floor looked like marble with matching white walls and gold trim. Directly in front sat a blonde man…man? You squinted a bit, his ears looked slightly pointed, but that couldn't be right. Maybe you really did drink tonight and just forgot.
Bakugo stared down, looking annoyed at what had just appeared before him and muttered under his breath, "A human?...”
"Sorry, could you tell me where I am? I must've had too much to drink and-"
"Shut the fuck up trash."
You flinched, "Excuse me!? I don't know who you think you are but-"
"Are you fucking deaf? I said shut your fucking mouth!" He stood and walked toward you until he was face to face.
The man was tall, blonde and had fiery, slitted red eyes. His facial features were pretty handsome as well, and was wearing a fitted black tank top with golden hems, black pants and high laced combat boots. So far your impression of him was poor and would only become worse as he roughly grabbed your arm as his other lifted your pencil skirt.
"H-hey! What're you doing!?"
"Tch!" he saw the marking on your outer thigh, a symbol showing a contract and who it belonged to. He let go of you and dusted off his hands as if he touched dirt.
You stared at your leg in complete shock that you somehow now had some strange tattoo that you definitely don't remember getting.
Izuku walked back in and caught sight of you, his mouth opened in surprise. "A human!? That's…that's not possible!"
"Can she be sent the fuck back?"
"Blood contracts are special…so…not that I know of..."
He growled in frustration, "I'm not dealing with a damn human! I have better things to do." he stomped out without a second glance.
"Umm, why did you say 'human'?" You noticed that this person also had pointed ears and claws…
Izuku rubbed the back of his head, "Oh right. I'm Izuku the assistant to whom you just saw, Bakugo Katsuki. The Demon Lord."
You stared blankly, "The..what?"
"The Demon Lord. You're in the Demon Realm." he smiled.
You couldn't believe your ears and your legs began to run through the doors, trying to find a way out until you came to one that led outside.
"Wait! You can't go there!" Izuku ran after you.
But as soon as you went through the doors, you gasped. The trees outside were enormous, like mountains and also saw what looked to be large winged creatures flying in the sky. There were guards posted by the doors you went through, as well as down the path directly in front. Everything was illuminated by two suns.
One of the guards looked over when he heard someone barge through and was surprised at what he saw.
"Woah, isn't that..a human!?."
You turned to look at who spoke and your eyes went wide. He had red hair but also horns, wings and a tail. Your legs gave out and you sagged to the floor, tears welling up and mumbled, "I'm dead, I'm dead…"
Izuku carefully approached you, crouching down to speak. "We're not going to kill you. You're our special guest. Okay?"
You slowly looked up and saw him smiling gently, with no malice hidden behind it. You rubbed your eyes, "Okay…"
He helped you up and then gestured for the guard to come over. "This is Kirishima, he's a shapeshifter and takes the form of a dragon. He'll walk you to your room while I let Kaachan know where you'll be."
"Huh, What's Bakugo have to do with….Wait!! Is she the-" Izuku covered Kirishima's mouth before he said anymore, telling him to shush. He then sighed and waved as he walked off to give their Lord the information.
You just stood, nervously waiting and Kirishima noticed, so he tried to lighten the mood a little. "So a human huh! I heard they have the best meat!....Uh not human meat! Like, other meat! We wouldn't eat humans!"
Then you began to laugh and he breathed some relief, "Thank you."
"Of course! Here, follow me. I'll show you around before we get to your room."
—-------------------------------------------------------------
Kirishima had walked you to the large garden with some interesting looking plants, the dining room and the tea room. You told him about the first place you were in and he said that area is the throne room, which you kind of guessed with the large fancy chair.
After some short exploration, the guard began leading you to where you'll reside and was walking in front of you. Your curiosity was getting the better of you as you watched his tail sway back and forth and reached your hand out to touch it.
Kirishima froze.
"Wow, your scales are really soft!" you started petting it gently when you heard a groan come from the redhead and looked at him. He was covering his mouth with his arm, trying to hold back any noise and his ears looked quite red.
The timing couldn't be any worse as the so called demon lord appeared around the corner of the hallway you were in and his gaze immediately went to your hands on the guard's tail.
"What…the fuck are you doing?"
Kirishima quickly swiped his tail out of your hands and stood at attention, trying to avoid the blonde's eyes. "Sorry my lord! I was caught off guard and-" Bakugo slammed his hand over Kirishima's mouth, crushing his head against the wall.
"You let a human pet your tail? My human?" his last words spoken low enough only Kirishima could hear.
You ran over and tried to pull Bakugo's hand off, "Leave him alone! What's the big deal!!"
The blonde turned his head, teeth bared and glared down at you, his eyes were glowing and fierce. You were a bit unsettled but didn't back down, staring right back.
"Tch!" He moved his hand away and stormed off.
Kirishima knocked his head back against the wall, "Fuck, I'm an idiot…"
You tilted your head wondering what was wrong, but he just motioned for you to follow him. Your room was just a little ways more and he opened the door for you. "Kirishima?"
"You're human so you don't know but uhhh…how do I put this. A demon's tail is pretty sensitive and petting or touching it is uhh.." he turned to look away, "usually something only mates do.."
You stared confused for a second until it dawned on you and your face flushed, "Oh….ooooh my god! I'm sorry!"
"It's fine! I should've noticed you were close… he's gonna kill me…"
"What!?"
"Don't worry! Not literally…I hope. But this is your place, make yourself at home!"
He waved before he shut the door.
You were stuck here for now, so you might as well see what's in here. The bed was pretty large, with posts and a canopy, lined with silken fabric. There was a separate room that looked to be the bathroom and then a rather large wardrobe. You took a look at it just to see and it was filled with clothes, women's clothes.
That was odd, it was like this room was already prepared for someone to be here.
You looked in the bathroom and there were a lot of perfumes, candles and scented bath oils as well. This was definitely set up for a woman to be here, but with how everyone reacted so far, it wasn't for you.
"That's fine… I wanna get out of here anyway."
—--------------------------------------------------------------
"Are you gonna find a way to send her back?"
"Fucking hell shitty hair… she's contracted to me!"
"Wait wait, a human can't be summoned…."
"I fucking know that! Those damned priests got a hold of my blood and changed the rune somehow!"
Izuku came running into the room with a book in hand, "Kaachan! I found it!"
He put the old book on the desk in front of Bakugo and opened it, showing him a circle that none of them recognized. They all read the description.
'Mated Rune Summon'
'Blood of the contractor must be used for completion. The summoned entity will be contracted and bound for eternity to that of which summoned them. However, the contract is not complete until copulation. If the contract is not fully formed by the time the mark fades, the contracted will return and a new summoning will be required.'
'Let it be known, if the contracted shows signs of affection to the contractor and it is not reciprocated, the mark on the contracted will emit poison, effectively killing the contracted over time.'
"Perfect. I'm not wasting my time on this."
"Don't you wanna atleast try to talk to her?” Kirishima asked
"Hah!? I highly doubt a human would want anything to do with me in the first place."
"She seems pretty nice!" Izuku said cheerfully
"Tch, maybe too nice for someone." he glared at Kirishima.
"That was!!..."
Izuku stood there confused until Bakugo told him what happened.
"EHHH!?"
Kirishima crouched and hid his head in shame while Bakugo knocked him over the head with his fist.
"My top guard must need more training if he doesn't notice a small creature sneak up and touch his fucking tail."
"Yes my lord…"
—---------------------------------------------------------------
You looked out the windows, noticing the suns were setting and sighed to yourself. You weren't sure how time worked here but when you entered the room, the suns were close to high in the sky which meant you've been in here for at least 6 hours. No one else has come by except what looked to be a maid to drop off some food.
You tried to get yourself to relax but couldn't help feeling just the slightest bit hurt that Mr. Important Demon Lord couldn't take time to check on you even once.
"Stupid jerk.."
Since it was turning dark, it was time to bathe and hopefully get some sleep. But when you took off your clothes you saw the weird tattoo again and tried to see what it said but it was no use. You even tried to see if it would rub off but no dice.
You turned on the water for the bath and smelled some of the oils, picking one you liked and added it to the water. It was there so you might as well.
The water had washed out the sound of anything else and didn't hear the door to the room open.
Bakugo wanted to check on you, not because he cared but because he wanted to make sure you were behaving. But when he turned to look around he caught sight of the bare skin of your backside in the bathroom doorway.
He sucked in a breath, his eyes raking in radiant skin laced over a slender back and rounded ass, down to the mark that branded your outer thigh.
Bakugo snapped out of it, moving his foot back to leave but he bumped into a table making noise.
"Hm? What was….AH!!" you quickly slammed the door shut. "Wh-what the hell are you doing here!"
He really wasn't used to someone giving him an attitude. "This is MY fucking home!"
Oh right, he had a point but why was he in this room?
"We don't have humans here, I need to make sure you're behaving!"
"I'm trying to take a bath 'Mr. Demon Lord'!! Don't they teach you any manners!"
He was getting annoyed now and broke open the door.
"Eep! What the fuck!" You were lucky you grabbed a towel, albeit it was small and barely covered your chest and inner thighs.
In his moment of anger, he had already forgotten you weren't clothed and the closer he was, the better you smelled until he did something even he wasn't expecting.
You felt lips crush against yours and a hot tongue slipped into your mouth. Your heart was racing as his hot hands ghosted along your waist. You could feel fangs on your skin as he massaged and teased your tongue. Your senses becoming blurred as you breathed him in. He smelled of dark woods and rain drops and tasted of melted warm caramel. He pressed his body into yours, pinning you against the sink before lifting you up to sit above it. Your hands wrapped around his neck, pulling him closer. One of his hands slid down from your waist to your thigh, stroking the mark.
Heat bloomed from his touch and you moaned loudly. His ruby eyes watched as you panted, your body flushed and then he realized what he'd done.
He let you go like he was burned and quickly turned around, leaving your room entirely and slamming the door.
There you sat, alone and confused at what the hell that was. He tasted amazing, smelled amazing, felt amazing….And what was with your leg? You rubbed the mark with your hand but didn't feel anything close to when his hand was there.
You've never experienced anything like that before, and it was just a kiss!
You slipped into the warm bath, sinking all the way down until only part of your head was out of water.
On the other side of the room, Bakugo was leaning against the wall in disbelief. He had better control than that! What the fuck was wrong with him!? Maybe it was because of the contract…he would need to avoid you until the time it fades so he can rid himself of these sudden urges.
Because there was no way he just fell for a human. Even if you were the most beautiful creature he's seen or that you smelled absolutely delicious….
"Fuck!" He ruffled his hair and began walking to his private chambers.
—---------------------------------------------------------------
The next day Kirishima knocked on the door and informed you that he could accompany you around the grounds so long as you stay away from Bakugo's main office, his chambers and the training area.
"Oh..Am I going to see him at all?"
Kirishima rubbed the back of his neck, remembering that Bakugo told him to make sure you do not see him whatsoever or he'd throw the redhead into the suns.
"He's uh, going to be pretty occupied with demon lord work so probably not."
You slumped your shoulders but with the way he left, you kind of expected this. Of course you were still upset and a bit hurt but you were just a human after all.
Kirishima wasn't expecting to see such a depressed reaction from you, considering how much you both argued yesterday. "Did something happen?"
It would sound ridiculous to say that the blonde barged into your room while you were naked and then shoved his tongue down your throat before just doing a complete 180 and left.
"Ah, nothing! How about some breakfast?"
—-------------------------------------------------------------
The next day was the same and then the next, until you had marked down that two weeks had passed and you still hadn't seen even a shadow of the guy. You had come to terms that whatever that kiss was, but it was nothing now which made it sting more.
Today was another day, except you started to feel a little strange and also noticed in the mirror that the mark on your leg was becoming lighter and also looking more like a bruise. You touched it to check, "Ow! Fuck that hurts…"
It felt like a sharp knife cut deep into your bone. You hoped it wasn't a sign of something worse to come.
But as the day went on, it was getting harder and harder to walk. You tried to hide it from Kirishima, just passing it off as a lack of sleep and asked if you could go sit in the garden.
When you arrived, you asked him if he could get you some tea, so he left to go prepare a cart. A minute passed when you heard what sounded like some women chattering and laughing. You peered over the floral bush and your eyes went wide when you saw Bakugo talking with what looked like a couple of horned, devil girls. They were wearing very tight shorts and cropped shirts, both with pretty faces.
You clenched your hand to your chest. You were jealous. But you knew you weren't even supposed to be here and he's expressed his disdain for humans.
Your eyes began to water, whispering how stupid you were and turned away from the sight of them. You couldn't stay here, didn't want to stay here, and so you swiftly left the garden and made your way to one of the rear exits of the entire property.
Kirishima had come back and called out for you. Bakugo was still there, hearing his guard yell for your name.
"Didn't I tell you to make sure she doesn't see me!"
"You weren't there when I led her here! And what are you doing with them anyway?"
"I'm getting sent mate proposals….I have to deal with them."
"Alright well, did you see her here?"
"Why the fuck would I see her?"
An attendant came running up to the two in a panic, "My Lord!"
"I don't want to deal with anymore fucking proposals today! Tell them to leave!"
"It's not that!" He took a deep breath, "The human! Someone said they saw her leave through the back gates!!"
"WHAT!?"
"Why would she leave!? She was fine when I…wait..a couple weeks ago it looked liked something happened between you two…" Kirishima glared at the blonde
Bakugo flinched and looked away.
"Bakugo. What the hell did you do?"
He grit his teeth, "I kissed her!"
Kirishima stood in disbelief, "You kissed her? And then… you told me to keep her away from you? Fuck bro! Even for a demon that's pretty fucking low!"
"Shut the fuck up shitty hair! She's gonna return to her world anyway!"
Kirishima was angry now and threw a punch at the blonde, knocking him to the ground.
"You stupid fucking-"
"She RAN AWAY Bakugo!! After she saw you talking to those succubi!! You don't think that maybe she might have feelings for you!!"
"It's just a contract."
"She doesn't even know that and why'd you kiss her then?"
Bakugo dug his fingers into the earth, asking himself what the reason for his actions was that night.
When you appeared in that rune earlier, he couldn't believe that it had summoned someone so alluring. But the stigma that humans had with demons had put him on his guard, thinking that you would be disgusted with him. Instead, you warmed up to being in this world quite fast.
And the kiss. You felt perfect against his body. It was incredible luck that even brought you here. Soon you would disappear and he would never see you again….
His heart ached.
He got to his feet and threw off his shirt to sprout his dark, black wings. "I'll find her." With a strong gust, he took to the sky.
Kirishima smirked, happy he knocked some sense into his friend.
—---------------------------------------------------------------
You had managed to sneak aboard a carriage that was heading into the mountain range. You weren't gone long yet but this would get you farther than just trying to walk with a bad leg.
You didn't know how long you were riding, but when it finally stopped you quickly got out and hid in the trees before anyone saw you. Taking a look around, it seemed to be a small village but it was pretty rundown.
You were about to start walking when large clawed hands grabbed you from behind.
"Hey look! I caught something here!"
Your screams were muffled with the hand over your mouth and it dragged you over to the rest of its group. Your eyes went wide and your heart raced. These did not look like demons that were in Bakugo's mansion.
Orcs, wolfmen and devils.
"What the? Is that a human!?"
"Hooo! We'll get a pretty penny for her!"
You struggled trying to get out of the grip on you, but they were way too strong. The wolfman came close and began lifting up your skirt when you kicked him in the nose.
"Gah! You little wench!"
"Hey! Don't damage the goods!"
"Hold her legs then!"
One of the devils grasped your ankles as the wolfman tried again and then saw the marking on your leg.
"She's contracted! And looks like her owner didn't want her!" The wolfman pressed his pawed hand on your leg and excruciating pain shot through your entire body, making you scream.
Bakugo wasn't terribly far and heard the noise, sucking in a breath. He flew in the direction of your voice, hoping he wasn't too late.
The Orc holding you let go and you collapsed onto the ground. Your leg was throbbing now and as you tried to move it, it only caused more pain.
"Hurry up and get her to the market!"
"That can wait. I've never had human before so let's have some fun first!"
They couldn't mean what you think they mean. But when their hands began to pull at your clothes you screamed the only thing you could think of.
"BAKUGO!!!!"
Suddenly something fell to the earth, shattering the ground around it and a gust of wind blasted at the demons.
Large ebony wings stretched out through the dust and as it settled, revealed ashy blonde with obsidian horns pointing to the sky. Blazing crimson eyes stared down at his prey as he readied his sharpened claws.
He looked to you and spoke gently, "Close your eyes and cover your ears."
You did as he told.
The demons realized who this was and paled.
"It's! It's!-"
"How dare you touch what's mine"
They all screamed and began running away, but they were too slow.
Bakugo flew out full force, easily slicing through the necks of each demon, spraying a trail of blood in his wake. None stood a chance against his rage.
He was done in a matter of seconds and landed back on the ground. He found some water in the carriage to wash off the blood before returning to your side, carefully placing his hand on yours.
You flinched and he quickly retracted but when you opened your eyes, you reached out for him and wrapped your arms around his neck as tears began to fall.
He was surprised at your touch, "Aren't you afraid of me?"
You shook your head.
He hummed, bringing his arms around you and closing his wings to cover you both. They blocked out the light and you lifted your head to see the most beautiful sight. In the darkness, his eyes shone like gemstones. He cupped your cheek with his warm hand, "Are you sure?"
Your heart was pounding, but not from fear. You were sure that somehow, through this out of world occurrence, you found the one being that was meant for you.
"Yes"
"Good"
His lips pressed against yours, a moan escaping you as he slid his tongue inside. You felt him swirl and lick, making you lose your breath. His teeth grazed your lower lip as he travelled down your neck and nipped at your soft flesh.
"Nnnghh!"
He groaned, enjoying the sounds you were making for him. But he needed to get you back home before he got carried away. He slowly let go, opening his wings and tried helping you stand, when you lost balance. You shakily held onto him for support, "I can't..stand up..my leg.."
He sat you down and lifted your skirt to inspect the mark, only to growl at what was happening. The mark was faded but it looked like it was poisoning your body, purple veins had spread up to your hip and down to your knee.
"I'm going to push on it okay."
You were worried but you wanted to trust him and nodded. He gently pressed his hand on the mark and it felt incredibly warm. He felt your body relax, "I'm sorry. For what I did before. I thought it'd be easier to let you return. This…" he massaged your thigh and watched as the purple lines began to retract, "Only happens when there's feelings of abandonment…and when there's affection.."
He looked into your eyes as he spoke the last words, searching for confirmation but added one last thing, "Demons take one mate to be bonded for eternity. If you choose me, you can never return home."
You may miss home but what did you have there? A boring job, a small apartment that you lived in alone and all your family had already passed away. If you went back, you'd never see him again and you couldn't imagine being without him, it hurt too much.
"I..want to stay. I want you."
He quickly picked you up, causing you to yelp. "Hang on."
You wound your arms tightly around his neck and then with a flap of his wings, you were in the air. It was breathtaking. But it wasn't the view you loved, your eyes only watched Bakugo.
—---------------------------------------------------------------
A few minutes later you were back at his mansion and he landed on the veranda to his chambers, to which he always kept the doors open in case he ever needed to take flight.
He laid you onto his bed and you watched as his wings folded in and vanished, his horns also dissipating.
But now your gaze was on his very muscular form and just how gorgeous he really was. You unconsciously licked your lip and he smirked, arching his brow.
"Something you like?~" he spoke low
Your eyes shot up to his, feeling the blood rush to your face. He walked over to you and whispered in your ear, "Take it off."
He stood back up, crossed his arms, waiting for you to move.
You blushed furiously as you slowly sat up and grabbed the hem of your shirt, lifting it over your head and dropping it on the floor. Then you moved your hands to slip your skirt down your legs.
"More"
You whined, feeling embarrassed by stripping in front of him. You avoided his gaze as you unclasped your bra, sliding it down your arms and onto the floor.
His eyes were carefully watching every movement, his hands squeezing his arms to control himself from just taking over.
You slid off the last piece of cloth, now only covering yourself with your hands. He huffed in disapproval, "Stand and let me see"
Your body was burning up as you slowly moved your hands to your sides as you stood completely bare in front of his hungry gaze.
He took in every curve, every inch of your radiant flesh. But he loved just how shy and glowing you were and needed to tease you more.
He gently grabbed your hand and placed it on the buckle of his pants.
"Now help me"
You looked at him, your eyes pleading but he just smirked. He really was a demon.
Your hands nervously opened and unzipped his waistband, noticing he wasn't wearing anything underneath and gasped as you let the fabric fall to the floor.
He grabbed your waist, pulling you flush against his body, feeling his hard heat throb against your stomach.
Mmm, looks like a tight fit~
Bakugo walked you slowly back to the bed until your legs hit the edge and sat on the sheets. Then took your hand and led you toward the head of the bed where he sat up against the pillows. He wanted to admire and feel your body move before he spoiled you.
He grabbed your waist and lifted you up to straddle him, placing your hands on his shoulders for balance. You could feel him line up at your entrance before letting you take over. Ever so slowly, you let your hips sink down and felt him begin to spread you open. You dug your fingers into his skin, moaning as he moved deeper and deeper.
Bakugo watched as he began to disappear inside you, groaning at the sight. "Haah~ That's it, keep going~"
"Nngh~"
You adjusted your legs a little more and pushed your body all the way down onto him. You whined as he throbbed pleasantly in your core. A hand moved to your back, pushing you closer to him until you felt his mouth around your pebbled flesh. His other hand on your hip, motioning you to move.
You whimpered as you watched him taste your skin and the second you began rocking your hips, you heard him groan, the sound sending shivers down your spine. He made sure to give both your soft mounds plenty of attention, pinching and sucking at each one. His mouth mapping every inch he could reach with playful bites, leaving wonderful red and purple marks in his wake.
You tried lifting up and back down, feeling his hand move to knead your ass. "Fuck, just like that"
You tried again, rougher and until you found your pace. His eyes watching you use his body for your pleasure, heat blooming in your core as you moved your hips to make him hit you just right.
He felt your body begin to twitch, your toes curling and nails clenched into his shoulders. "You like fucking the demon lord?"
You whined, "Y-yes~"
He growled, "Cum for me"
His command went straight to your core, pounding him harder until you felt your body burst with sparks, moaning loudly as you grinded on his cock as tingling waves passed through your skin.
Bakugo wasn't going to let you rest and held you as he flipped you both over. He slowly slid out, making you whine and turned you onto your belly, situating you to be on your hands and knees.
He rubbed his heat against your swollen lips, teasing you as you tried to back your hips onto him but received a smack to your ass.
"Mmm, it's my turn"
His hand squeezed your marked thigh and you moaned his name loudly, bucking your hips back again. Another smack, making you mewl.
"If you want it, beg"
The way he spoke was incredibly sexy and your body needed him desperately.
"P-please!"
'smack' "Nngh!"
"You can do better than that"
"Please fuck me…my lord"
He gripped your hips and pushed his heat roughly into your soaking entrance making you cry out. Your hands were braced in front of you, clenching the sheets as he began to move.
Bakugo slid out and teasingly back, feeling how your walls quivered and sucked him in. His cock stuffing you to the brim as he began bucking his hips faster. His pace became brutal and hungry, searching for that spot to make you melt.
"Ka-Katsuki!!"
He groaned, loving the sound of his name from your lips but he never allowed that, not yet. He pushed your upper body down so your ass was angled higher and fucked you deep. He spoke between heavy breaths, "Who said you could say my name, hm?~"
You cried out as he hit your tender bundle of nerves, tension coiling quickly with every thrust. "Haah~ You like my cock that much?~"
"Y-yes my lord~"
He mercilessly pounded into you until you screamed out, your walls contracting around him tightly. Then he pulled out and flipped you onto your back and threw your legs over his shoulders before he thrust deeply back in. You held onto his arms while he continued his brutal pace, your toes curling as you felt your body build up heat again. He leaned down and whispered into your ear, "Now say my name so everyone can hear it~"
His hand moved to your thigh, squeezing the mark causing immense pleasure to pulse out and forced your core into a burst of electricity. You screamed out, "Katsuki!!!!!"
You writhed under him, your body too sensitive, making you mewl with every thrust. He felt his own end close, tension brimming over. With one last thrust he bit roughly down into your neck, groaning as he came undone. His horns and wings sprouting and stretching out, feeling the immense shocks rip through him, spilling himself deep inside you.
He milked his cock into your core, not wanting to waste a single drop.
You watched as his demon form dissipated again and he slowly got up, making you whine at the loss.
"You're quite the greedy human~"
You blushed furiously at how many times he made you come. You couldn't help it! He felt incredible.
He smirked and then moved your leg to inspect the mark. It had changed shape into a black flower with some writing that you couldn't understand.
"What does it say?- AHH!!!~" he pressed the mark and the pleasure was even stronger now.
"Hmm, I'll have fun with this if you misbehave."
"Katsuki!"
"And the mark says my name" he smiled.
He stood up to slip his pants back on and remembered one other thing, "You don't know this but that bite on your neck is also permanent, it's my mark as your mate."
You touched your neck, noticing it didn't hurt but felt quite deep. You admired his back as he ran his hand through his hair, never imagining that you would find yourself with an otherworldly being. A demon lord at that.
You felt your heart swell, already mad in love.
He grabbed a robe for you, but was rather translucent and looked at him questioningly. "What? You're not leaving this room until I've had my fill, this is just so you're comfortable."
You felt your skin heat up, "You really are a demon."
He laughed softly and lifted your chin with this finger, "A demon who loves his human very much"
He pressed his lips to yours, a sweet kiss from your beloved.
