It was perfect. You had fake blood all over your room, staining your once blue sheets, but the costume was perfect. 

For Halloween, your friends had decided to host a party at one of the dorms. You and your best friend, Jeongin, had decided it would be the best idea to dress up as Sidney Prescott and Ghostface. Your costume was quite easy - you already had an old denim jacket you could cover in blood, and a basic lilac top to go underneath it. When put together with a simple black pair of jeans, you felt completely ready. Your costumes were going to be the best.

The Instagram pictures would be amazing, too, you decided while walking to the party. You didn’t have a long way to walk, and it was quite amusing listening to the kids screaming for candy outside people’s doors - but all you could hope was that one of the members of 3Racha had actually cleaned the dorm this time, and not left it all on Hyunjin.

Music was already booming when you arrived, reverberating around your sober brain and making you wince. Would you regret coming here?

You realised you really did regret it, when the front door swung open and you were met with fox-like eyes in a… a fucking Pokemon trainer costume. Felix emerged from behind him, sharp yellow ears perched on his head and his cheeks covered in red. 

“Listen,” Jeongin began, gloved hand reaching out to you. You sighed, shutting your eyes. “It was Felix’s idea. Look at him. He’s really convincing, and I’m sorry I didn’t text, but Chan’s put this stupid no phone ban on and-”

“Look!” Felix chirped, and when you finally saw him… well, you understood what Jeongin meant. He was in yellow dungarees, tail wrapped on a string around his waist and little ears bobbing with his glee. When he looked at you, his face fell. “Oh. Oh, I’m so sorry. Did you guys have something planned, or-”

“No, not at all, Lixie,” You murmured, pulling him in for a hug. He really was so cute. No one could resist him. “I’ll find my Ghostface somewhere.”

Felix nuzzled into the hug, wrapping his arms around you, before he was squealing. “Seungmin’s dressed up as Ghostface! Oh, Innie, did you plan this?”

You blinked, turning to Jeongin. Seungmin was your arch nemesis, but only purely on the basis that you both had some heavily unresolved sexual tension.  Jeongin wouldn’t do this to you - or so you thought, because when you looked at his face, he was looking extremely guilty. “I know you have some… issues, but it needs to end now. It’s making things awkward, and, and… you can take pictures together, y’know? Then be friends,” He was mumbling, scratching the back of his neck awkwardly. His Pokemon hat obscured most of his face, but you could still see the pout on his lips. Fuck this. You had the two sweetest men in front of you apologising, expecting you to be angry at them, but even you weren’t that mean.

You sighed, finally pushing past the two figures to enter the party. You were immediately attacked by a black plastic streamer dangling from the ceiling, and you swatted it away with a grunt. “It’s fine. Let’s do the pictures, then.”

It had always been the plan - to take pictures all together before the party really got into full swing. You had a feeling you’d been a little late because there were already quite a few people there. Still, you diligently walked into the kitchen behind Felix and Jeongin anyway, where everyone was standing around, conversing.

There he was. Ghostface mask pulled halfway off of his head to reveal dark, menacing features and a black cloak draped over his slender figure. Chunky black boots made an echoing noise as he tapped his foot impatiently on the tile, sipping out of a glass with one gloved hand and the other holding - a knife. It glinted in the light as he spun it around with his fingers, playing way too comfortably with the blade. Oh. Oh, no. Someone was playing a practical joke on you. 

“Is that knife real?” You squeaked, and Seungmin turned to you with a glare. “Like, it’s not a prop…? Why do you have a real knife?”

Seungmin raised an eyebrow, then his lips were curling upwards with a smile. “To finally kill you with.”

“Haha, that’s so funny,” You deadpanned, but half of you was considering if he was being genuine about it. It wouldn’t surprise you - he was a sadistic fuck, always had been since you met him. It was why you wanted him so bad. “Let’s take these pictures. I’m already over it.”

Felix fiddled with his camera, flicking off the lens cap and trying to get it in the perfect position on the counter. You scurried in front of Seungmin as he walked over after placing his cup aside. Once Felix had set the timer, he ran in front of the lens and clutched onto Jeongin. Oh, yeah. What was Seungmin supposed to do, given that you were matching?

You had your answer quickly. With one gloved hand, he pulled his mask down and pulled you into him by the waist, and then he was positioning the knife at your exposed collarbone. It nipped teasingly, the blade threatening to draw blood. You looked down in shock, only to see Seungmin’s hand confidently holding the handle - god, was he skilled with this? He hadn’t killed people, hopefully, but… what if he was into something like this?

Wetness pooled in your panties at the thought. It’s a kink straight out of your deepest, darkest desires. The idea of being too scared to move in case the knife bites at your skin, dripping crimson liquid down your body only to be lapped up by the blade again… yeah. It was hot, and for some reason, with your fake-enemy pressed against you, it was even hotter. You didn’t even blink when the flash went off, too focused on trying to keep your breaths even. 

Seungmin dropped his hand once the picture was taken, and then he yanked the mask back again. He was staring at you with a bewildered expression, but he looked somewhat impressed. Pulling you to one side by your arm, he gripped your waist again, trapping you against the wall so he could whisper into your ear. “Did you get turned on when I held that knife to your neck?”

“No, what’s wrong with you-“

“I heard you holding your fucking breath,” Seungmin hissed. “That’s fucking insane, you know? Dressing up as Sidney and then getting all… like that. It’s like you wanted me to do it.”

You huffed, crossing your arms over your chest. Seungmin’s eyes flitted around your face. “I was actually meant to match with Jeongin, so maybe I wanted him to.”

“Oh, c’mon,” Seungmin scoffed, rolling his eyes. He pinched his temples, and then he sighed. “I know you want to fuck me. God, I want to fuck you too, so bad. I’m sick of playing this stupid push and pull when I could be upstairs fucking you with this knife to your neck right now.”

Your eyes widened. You let out a puff of air, trying to find the words to say, but you only noticed that fuck, Seungmin was awfully close all of a sudden. His breath was heavy on your burning cheeks. When you looked around the room, you could see that no one had noticed the two of you - Felix was too busy still jumping around and Changbin and Jisung had dressed as Peter Pan and Tinkerbell. You wanted to coo at Changbin, his bulging arms so adorable in the little green dress and wings, but you were definitely more engrossed in what Seungmin had to say.

“The party. We can’t leave, you know?” You finally spoke, and Seungmin pulled back. You wanted to cry. He looked around the room, nodding, before he was pulling the mask back onto his face and obscuring his annoyingly perfect features. 

“Half an hour. Jisung’s room, upstairs. Is that alright with you?” His voice was muffled, and you had to crane your head a bit to hear him. You nodded nonetheless, and he gave you a quick wave before disappearing into the crowd of dressed up men. 

You sighed heavily. This was about to be the longest half an hour of your life.

˚ʚ♡ɞ˚

Jisung’s room was chaotic. You had literally no idea why Seungmin had decided on his room out of everyone’s - surely Hyunjin’s would be better, or even Chan’s with the mood lighting? You opened the door anyway, entering the small room and stepping over piles of clothes to lay back on the bed. At least the bedsheets were cleaned. Jisung’s lamp was the only source of light, leaving the room basked in a creepy orange Halloween atmosphere. It definitely fitted the setting.

It had been exactly half an hour. Seungmin was late. Was he ever late? In your whole pseudo-friendship, you were sure he’d never been late, and-

The door burst open and a masked figure emerged. You jolted, sitting upright on your hands and blinking at the man in costume. It briefly crossed your mind that you couldn’t even be sure it was Seungmin, and then he was tearing the mask off, throwing it aside. 

“It’s still me,” He said, tone soft. Was he a mind reader as well as a borderline psychopath? You nodded, wiggling forward on the bed when he sat across from you. “Are you sure you want to do this?”

“Did you bring the knife?” You responded. Seungmin burst out laughing, and then he was bringing it out from his jean pocket, beneath the cloak. 

“You are very fucked up. Has anyone ever told you that?” He murmured. You stared at his gloved palms as he threw the knife aside, moving on the bed to pin you down against the mattress. You wiggled impatiently, spreading your legs to allow him between them. Your chest heaved, staring up at him with doe eyes as he blinked down at you.

“‘M not fucked up,” You mumbled, pouting. Seungmin chuckled.

“What was it Billy said in the movie again? ‘It certainly fucked you up, it made you have sex with a psychopath’? Is that not what’s happening right now, baby?” His breath was hitting your face again, and you just couldn’t help it this time. With one hand on the back of his neck, you pulled him down, pressing your lips against his in the filthiest kiss you’d ever shared. Seungmin groaned, hands meeting your waist and delving into your mouth with his tongue. You let him nibble into your bottom lip, let him nearly draw blood with his teeth until you were whining, bucking your hips up for more. 

You whined, chasing his lips for more kisses. You heard fabric rustling, and then Seungmin was pressing an ice cold blade to your neck. You shifted immediately, laying back against the pillow and looking up at Seungmin obediently. He just smiled, appearing borderline menacing in the dim lighting of the room. You were so fucking wet.

“You do get off on this,” Seungmin mused. He leaned back on his ankles, letting the knife drag down your body. With a clean swipe, it was cutting through the fabric of your tank top and leaving you in just your bra. “Should I make you bleed, hm?”

“You can- you can do anything you want, Seungmin,” You sighed, arching your back to get more of the feeling of the blade against you. Seungmin bit his lip, dragging the blade down to your jeans. He wouldn’t be able to cut through that fabric - it’s too thick, he’d need something sharper. You could practically see the cogs turning in his head and then he was shaking his head, unbuttoning your jeans and yanking them down your legs. They balanced precariously on one ankle, and you kicked them off before eyeing Seungmin up and down. “Are you… gonna get naked, or?”

“I have different plans for tonight,” Seungmin replied quickly. He gripped the knife firmer this time, until he was dragging it down to your underwear. You knew you were wet, and you shut your eyes and moaned loudly when he pressed the blade into the wet spot forming in the fabric. You thanked every god that the music was still just as loud as earlier. “I’m going to finger you and play around with this knife. I don’t think you could handle more tonight.”

He was right. Another thing that irritated you beyond belief was the fact that Seungmin seemed to read your mind. First with your silly knife play kink, and now with the fact that you definitely couldn’t handle full blown sex tonight. You would’ve tried, and gotten yourself all fuzzy over it - but he knew better. 

“Okay,” You agreed. He hummed once more, and then he hooked the blade into the lace of your underwear, cutting them off of your body. He was a bit heavy handed though, and your legs thrashed when the blade nicked your skin just a little, causing a small crimson red cut to bloom on your hip bone.

“Oh, would you look at that?” He ogled the cut, running his thumb over it. It made you whine in pain, yet he ignored you and thrust his thumb into your mouth. The taste was tangy, a bit too metallic for your liking but the whole thing was so fucking hot you couldn’t deny him anything. “Did you like that, too? Okay. We’ll explore that another time.”

Seungmin threw the knife aside once more, and then two long fingers were pressing into your folds. You laid there with legs spread, letting him explore every dip and crevice in your pussy and examine how wet you were. You knew you were dripping, and he did too - it was just a waiting game. 

You squirmed, bucking your hips up. “I’m wet enough. I promise that I am, just-“

You gasped when he pressed the knife against your throat again. You hadn’t even seen him grab it. “Stay fucking still,” He warned. “I decide when you’re ready.”

Well, you could definitely get on board with that. Seungmin sunk his middle finger into you nonetheless, meeting no resistance. Your hole was dripping around him, leaking down to his knuckle and making him sigh in approval at the sight. He still had his gloves on, the faux leather buttery and smooth inside of your hole. “This pussy’s tight, huh?”

“I’d clench it for you,” You breathed out, letting one of your hands grab your tits over your bra. The knife was still pressed tightly against the column of your throat, but you managed to pull your tits out of the lace, making Seungmin’s eyes instantly flit down to your pebbled nipples. He started to thrust his finger inside of you, the material of his gloves dragging on your rim. “I’d- I’d clench around your cock, Seungie. Make it so tight for you.”

“Yeah?” Seungmin breathed. On his next thrust in, he pushed another finger in, and then he was curling two directly at that lovely spongy spot inside of you. “I’ll look forward to it, baby. Do my fingers feel good?”

“So good,” You gushed, tweaking your nipples with your fingers. “It’s so good, and- the knife, oh god-“

“Is it like you imagined, yeah?” He moved up to your side, easing his pressure on the blade so you could turn your head and kiss him. It was just as filthy, and he moaned in approval when your walls fluttered around his digits. When he pulled away, a string of saliva connected you both. “Maybe next time, I’ll fuck you with the handle of the knife.”

You keened, starting to bounce your hips against his hand. He obliged with your movements, pressing his palm up against your clit and letting you grind the sensitive bud into his calloused hand. It was just the right amount of soft and rough, making your toes curl in your socks and your orgasm build steadily, a white hot pleasure in your pussy. 

“It’s- I need it-“

“God, do you even know what you need?” Seungmin chuckled, kissing your cheek. “I think you need to cum for me, don’t you?”

You nodded erratically, letting your head fall onto his shoulder. Seungmin dropped the knife to his opposite side once more, replacing it with a firm grip to your throat with his spare hand. The sight of his gloved digits around your throat and restricting your airflow had you wailing once more, gripping his wrist and grinding with renewed fervour. 

“I think- oh, I’m gonna cum,” Your lips parted, letting out muted moans and whines at the feeling of his fingers inside of you. “Oh, yeah, I’m gonna cum!”

“Cum for me then, no need to make a noise,” Seungmin was still amused, and you gasped before you were cumming. “That’s it, there you go.”

You felt your hole gush around his fingers, soaking the material of his gloves with white cum and your clit throbbing through your orgasm. It felt good, not only to cum but to also finally have some tension resolved with such a prominent person in your life. 

When you finally came to, you were still gasping, breath heavy and burning your lungs with every exhale. You heard Seungmin coo at you, laying back and dragging you onto his chest. 

“Good?” He questioned, and you nodded.

Then, something hit you. “Seungmin?” He hummed in response. “You cut my shirt open. What do I wear for the rest of the party?”

Seungmin stopped breathing, and then he burst out laughing, full body laughs wreaking havoc on his body. 

“It’s not funny!” You whined, but you were giggling too, slapping his chest playfully.

“You can wear the cloak, baby,” He kissed your nose. “I have clothes on underneath.”

You hummed, nodding. “You still have to wear the mask though.”

“Fuckin’ freak,” He mumbled, but he was still grinning.

“You like it.”

Seungmin kissed you again, chaste and sweet. “Unfortunately, yes.”

lullaby

"What is it?" Seungmin asks when you stand in the doorway, fiddling with your oversized cardigan. He was trying to finish a project and your figure was just standing there in the corner of his eyes for a couple minutes now.

"Can you sing for me?" you ask meekly.

These days, sleep doesn't come as easily for you. You keep tossing and turning at night, unable to shut down the chattering in your brain. So when Seungmin asked if he could borrow your work room for a change of scenery, you quickly approved with another agenda in mind.

"Why should I?" he joked. You didn't expect him to agree so quickly though, and you already prepared a counter for his witty remarks. But standing here, now, you just don't even want to try. He turned to look at you, feeling a knot in his chest from the way you just looked so... empty. "Can you wait 5 minutes? I'll send this email first."

You nodded before walking back to your room and lying down in your dimly lit bedroom.

Seungmin came not long after, standing at the foot of the bed, looking confused. What was he supposed to do? Just sit there and sing? should he pat your feet? or head?

"Do you want to cuddle?" he asks, surprising the both of you. He lowers his head, cursing silently. "I mean, I heard it helps you fall asleep faster?"

"Are you okay with that?" you ask. He nods before getting on the bed, rubbing his hands on his jeans before pulling you closer.

"Has it been going for long?" he asks when you're trying to find the comfortable spot.

"On and off," you hesitate, trying not to make it sound bad. Seungmin only nods, parts of him wondering what calmed you down before and what pushed you to ask him to sing just now. But he didn't ask, not now, he thinks.

When you're safely nestled into his chest, he starts singing the lullaby, humming on random parts because he forgot the lyrics. The moment he feels you relaxed, he pulls away a bit only to cause you to come back to consciousness.

"Sorry," he whispered, then proceeded to sing again from the first line. The atmosphere is starting to affect Seungmin and he tries his best to fight it off.

"Everything's gonna be okay," he murmurs, well aware that you have fallen asleep minutes ago. He slowly drifts off, following you to the dreamland.

"I'll guard you." He promised genuinely before letting his eyes close completely.
