[Murderer!Dark x Student!Mark]

Unedited
Mark's POV
I was sitting on the couch, my arms folded while sulking.

Recently, my parents hired a babysitter because they were going on a buisness trip and won't be back for a while.....and because there was a murderer on the loose.

I just came back from school and my parents told me the news, they said the babysitter would be here any minute now.

Way to ruin my day.

So here I am, sitting on the couch being a salty and sulking bitch.

"Now, now, darling, no sulking. You'll love your babysitter, I just know it!" My mom excitedly said, a bright smile on her face.

I continue sulking "But mom, I'm sixteen! I can take care of myself!" I protested.

"But can you take care of yourself when there's a murderer on the loose? Ten bodies in just one week! That murderer is dangerous, sweetie, you could be next!"

"But mom-" I dragged, but my mom beat me to it.

"No buts, honey. You are hanging out with your babysitter and that's last, Mark"

I huffed, going back to my slouching position, being twice the salty and sulking bitch I am.

After a while, there was a ring on our doorbell and my mom smiled, looking at me "oh, here he is, Mark!"

My mom went to opened the door, and my babysitter came in. I didn't see my babysitter's face because he was behimd the couch and because I didn't want too.

I groaned, slowly standing up and dragged my salty ass to the door, leaning over it with a frown on my face.

"Now, honey. Be good and do whatever your babysitter tells you to, alright?"

I grumbled but nodded, and my mom kissed my forehead and I hugged my dad. I watched as they got in the yellow taxi as it drove off, leaving me with my babysitter in the house.

Well, if I'm gonna stay here with my babysitter might as well know what he looks like.

I turned my head to look at him and my eyes widen.

He was the most gorgeous man I've ever seen in my entire life.

He had fluffy raven hair, a built figure, red eyes that somehow seem mesmerising, and greyish-tan skin. He was wearing a plain black t-shirt, black pants. Everything black.

He must have caught me staring because he grinned slightly, approaching me. Soon, he was just a few feet away from me.

"Hey there! I supposed your not really keen in having a babysitter, are you?"He said, his voice deep and buttery.

Oh my god, his voice makes my knees weak.

I nodded, not really looking at him.

He chuckled, holding a hand out to me to shake.

God, his laugh is infectious.

"The name's dark and you can just act me as a friend that's having a sleepober with you until your parents return, alright?"

I nodded, sheepishly returning the hand shake "m-my name is Mark..."

Did I just stuttered?

He smiled and led us to the couch, plopping down on it as he looked at me.

"Okay so let's get to know about each other. I'll start first, no matter how personal."

"How old are you?"

"Oh, right to the point, huh? Well I'm twenty-five"

"Are you new here? I've never seen you around here before..."

He chuckled, and my heart fluttered. "Well, I've actually live here for a few months now, I actually seldom went out you know, I like to keep to myself mostly..."

"What do you like to do? You know, as a hobby..."

His eyes seem to lit up at that "well, I like to play the gituar, video games....."

I beamed brightly "video games?! I love video games!" I exclaimed happily, grabbing his wrist as I dragged him up to my room, and dragging out my consoles and what not.

"Care for a round?" I smiled as I looked at him, tossing him the controller. He smiled as he caught it, smirking in the slightest.

"Oh, your on"

Time skip~

We have been playing video games for hours and eating pizza we've ordered along the way.

Looks like Dark and I were tie.

But, unfortunately, it was time for me to sleep. I wanted to stall time, hoping Dark won't notice, but he saw right through me.

So, in the end, I went to bed, wrapping myself up in a burrito as I drifted off to sleep, thinking about Dark.

1 week later~
Dark and I had been fairly close over this one week, and I have fallen more and more in love with him, and the murderer is still out there.

So far, the murderer had kill another seven people, and I'm surprised that I'm still alive, and even Dark.

And speaking of Dark, I had a slight suspicion of him. I've realized that every night after I sleep, he would go out to one of his night walks, and every time a person dies.

But, Dark couldn't be the murderer, right? He's so sweet and kind, his like a big teddy bear.

Maybe is just my imagination....maybe I'm just overthinking, yeah.

Dark would never be the murderer.

1 day later~
I was waiting for Dark to fetch me from school, when I suddenly heard clicking from a pair of heels.

And I know that pair of heels anywhere.

Britney Buffington. (Lol idk)

Britney is basically a bitch, she's tan, puts 50 pounds of makeup, has big fake jigglytits, black hair, and brown eyes and she always wear over revealing attires.

"Mark!" She squealed, using high ass annoying pitch voice as her heels clicked faster.

I groaned, rolling my eyes as I put on a fake smile.

"Hey there Britney..." I said, my voice itself clearly show that I'm not interested in her bullshit.

But, apparently she couldn't see that.

"So, Mark. Why are you still here? Aren't you supposed to be home by now?" She said, literally shoving her fake tits to my face.

I lightly groaned, taking a step away from her but she noticed it, taking a step towards me, her fake tits back to shoving my face.

"So...I was wondering....we haven't really hang out much this year.."

Honestly, I would rather take a thousand kick to the balls than spent another 1 more nanosecond with you.

"Yeah...I don't really have time for anything"

"Well, if you change your mind..." she said, taking out a pen and a piece of paper, writing down her address and phone number, before handing it to me "you know where to find me"

I wanted to rip it in front of her. But I am a kind fucker, so I took the paper and slip it in my pocket, flashing her a grin that's clearly fake.

She gave me a sweet smile and I grimaced, looking off to my side and my eyes widen.

Standing there was Dark, with an angered look on his face and I swear the word murder was written all over his face and his eyes.

Especially his eyes, his red eyes was burning with fire, like he could create hell from just a snap of his fingers.

Britney followed my gaze and sneered while scoffing, flicking her hair.

"And who are you suppose to be, his boyfriend?"

I merely blushed at that word, looking to the side.

Dark stormed up to me and grabbed me by the shoulder, spinning us around so I was behind him.

"Actually..." Dark started, his voice surprisingly calm despite his expression just now "I'm his caregiver and I would like to take him home"

Britney rolled her eyes and looked to the side, twirling a strand of her hair "ugh, like Mark needs a caregiver like you when he could have me..."

I quickly exchanged my position with Dark and looked at Britney, wanting to get out of this as possible "yeah, um, his taking me home so, yeah"

"Oh c'mon, Marki....." she battered her eyelashes "I could take you home"

"That would be lovely but no, Dark is here to pick me so I'll just have to go home with him"

She huffed and folded her arms "I don't know why you even care about that scum but alright, if you need me, you have my number"

I scowled but nodded, quickly pushing dark as we stepped in into his car.

Once in, Dark was grabbing the steering wheel so hard, he looks like he's about to break it.

I put my hand over his and he instantly relaxed, smiling at me which I returned the smile at him.

"You don't have to worry about her, she's a bitch, okay?"

Dark chuckled at that "I kinda knew that when I saw her"

I giggled, and I took his arm, hugging it as we drove back to my house.

Dark's POV
My heart fluttered when Mark did that, making me smile the entire time on the ride home.

When we reached home, I cooked him a meal and we played video games until he had to sleep.

He changed into his pajamas when he showered, so his attire was in the basket, waiting to be washed.

Perfect for me.

I took the slip from his pocket into my hands, staring at it with a smirk on my face before shoving it in my pocket, before continuing washing his clothes.

Just you wait, Britney bitch.

Just. You. Wait

We will meet very soon.

Very. Soon.

Next day
It was around midnight when I woke up, and my heart fluttered. He looks so peaceful, like nothing could bother him at all.

I smiled softly as I brushed some strand of hair from his face and he smiled softly, snuggling into the blankets more. I can't help but softly 'awe' at the adorable sight.

But my smile was short lived as I remember my task at hand, my smile going into a smirk.

I took my phone and added Britney's contact in my contactlist, sending her a message.

M-Hey Britney ;)

B-who's this?

M-It's me! Mark, remember?

B-Oh, I knew you would text me, Markimoo ;)

I merely growled at that text, keeping my calm as I continue with the conversation.

M-Yeah. Anyway. So would you like to come to my house tomorrow?

B-What about your babysitter?

M-Oh don't worry about him. His only my babysitter, not my boyfriend.

B-alright then, Marki. I'll be there tomorrow, Marki ;)

I smirked as I shut down my phone, looking at Mark as I smiled, going under the covers as I basically spooned him from behind, nuzzling my face from behind the crook of his neck, breathing in his scent.

This have became our daily routine and I'm happy that I get to do this to him. Mark said that he was scared of the dark so I promised him I'll stay with him till he sleep but ended up cuddling with him and he was fine with it.

I snapped out of my trance as I felt him snuggled closer to me, and I smiled, slowly drifting off to a peaceful dream.

Next day~
After fetching Mark to school, I quickly went home to prepare everything. Mark had a basement to store stuff and it was barely full so that was quite easy for me.

I took a wooden chair and table, placing the chair in the middle of the basment and the table a few feet away from it, placing all my tools on it.

I took Mark baseball bat and waited for the door to open, an insane grin on my face.

This might be the best murder I've had in a while.

After a while I heard the door opened and the click of heels and my grin widen as I walked up the stairs, and open the basment door to reveal Britney in an over-exposing shirt, her back facing me.......I don't even know if you could call it a shirt.

She was wearing an extra short and tight black pants, showing off her plastic ass, her shirt was practically only covering her fake tits and they were tight too.

"Ah, there you are Mark-" she paused as she turned around, seeing me as her grin drop, replaced by a frown.

"Ugh, I should suppose it was you. Your just ruining my date with Mark"

My eyes furrowed, but I stayed silent.

"Hey! I know you can talk, so start talking. Amd maybe if your good by the time Mark comes back, maybe you can see us fuck"

That was it.

I took my bat and swung it straight for her forehead, she stumbled back and collapsed to the ground, hitting her back of her head with a thud.

I grabbed her hair and dragged her down to the basement stairs, and tying her to the chair, tightly.

About 15 minutes later she woke up and I watch her from the darkness.

Her eyes widen as she struggled as she shouted for help. But, unfortunately for her, the basement is soundproof for some reason, so nobody can hear her accept for me.

I chuckled as she instantly stopped, trying to find me as I stepped out of the shadows, hand clasped behind my back.

Her head snapped towards my direction and she growled, glaring daggers at me.

"Let me go this instant! Do you know who I am? I'm Britney fucking Buffington!"

"I don't care who you are. Now, do you know why your here?"

"I'm here because you want to ruin my fuck date with Mark!"

I growled as I grabbed the knife from the table and slashed her cheek, blood pouring from the cut as she whimpered, looking at me with fear in her eyes.

"No. Mark is mine, he belongs to me and me alone. And if you want to interfere, I'll kill you."

"Your not even close to being his boyfriend!"

I smirked "and that's why your here to witness it live, I will mark him as mine right here in this place. You will hear him scream for my name....."

"He doesn't like a fag like you"

"At least I don't need fake tits or ass to win a guys heart"

Before she can protest, I taped her mouth and slammed the door shut and went up to fetch Mark from school.

The ride home was sweet, with Mark hugging my arm and grinning with his eyes closed like a kitten begging for affection from their master, which he was.

I smiled sweetly at him. This was another thing that became a daily routine for us, and I loved it, very much.

As we arrived home, Mark instantly threw himself to the couch, face planting on it, and I could hear a muffled sigh from him.

"Home sweet home....."

I chuckled, sitting at the end of the couch, softly patting his head and he leaned into the touch, lightly purring.

"Anything good happening today?"

"It was all normal, just the fact that Britney wasn't at school to bitch me around"

I inwardly smirked at that, knowing that Britney heard that.

The basment was soundproof on the inside but not on the outside.

I stood up and went to the kicthen, decided to prepare Mark a meal before the great reveal on his basement.

"What would you like to eat, Marki?"

"Anything..."

I decided to cook him something simple, and putting it on a plate after I'm done.

Mark ate and we played video games for a while, until I realized it's time to give Mark the big reveal.

I turn to Mark "hey Mark, hang on, I gotta grab something."

Mark nodded, not even looking at me as he continued playing the game.

I quickly went down to the basement and smirked at Britney "your in for a fun, honey"

Her eyes widen as she shook her head, screaming random things but I don't understand anything because of the binds so I'll just act like she's excited.

"Mark! Could you come down to the basement and help me with something?"

"Yeah, coming!"

I heard rush footsteps getting closer and closer, until it was right outside the door.

"So, dark what did you want?"

"Come down here and see for yourself"

Mark came down and when he was at the last step, he froze and I took the tape of Britney.

This is either go two ways. And I was hoping it was the one I want.

"Mark! Oh, thank god you came! This fucking psycho kidnapped me here and tie me up in this basement and now he even cut my cheek and tol-"

Britney stopped her babbling and I saw the hope drain from her eyes. I looked over to see Mark with a red face, holding his stomach as he tried to contain his giggles, but burst out laughing instead.

Sweet, kind, adorable Mark was laughing crazily like a madman, holding his knee in one hand and his stomach in the other as he struggled to breathe.

"Oh my god, this might be the best thing I've ever seen!"

(HA! PLOT TWIST BITCHES)
I looked confused, and so does Britney.

"Wh-what do you mean, Mark?" Britney stammered and Mark glared at her, snarling.

"Shut up you whore, I wasn't talking to you"

That caught me by surprise but my heart fluttered knowing Mark liked it.

Mark turned to me and gave me the sweetest smile,, walking up to me as he pecked me on the cheek, making me slightly blushed.

"Darki, you did this for me?" He said, battling his eyelashes innocently.

My smile widen as I ruffle his hair to which he giggled, smiling adorably.

"Oh, anything for you, Marki"

We were having a lovely time, until some bitch had to interfere. Which, she in fact was.

"Are you serious, Mark?! You betrayed me for this low life whore who's not even worth half than me?!"

That was it.

Mark took the knife from me gently, before stomping to Britney as he slashed her across the other cheek.

"Shut up you whore! Your not even worth the half!" Mark snaps at her and she whimpered, staying silent.

"Now that there's done...." Mark said, carelessly dropping the knife which ended up on her foot as she screams in pain.

"Whoops..... the knife slipped" Mark grinned, bending down as he harshly took the knife out again, followed by her screams.

Marm stood up and gave me back the knife, and while I was distracted with it, Mark smashed his lips against mine.

I was surprised at first, but then I relaxed, closing my eyes as I kissed back, wrapping my arms around him.

Mark hummed as he wrapped his arms around my neck, pulling me closer. I looked to the corner of my eye, seeing Britney with a hopeful look on her eyes. I smirked as I broke the kiss, looking at Mark with a smile, which he returned back.

"She still wants you. It's obvious in her eyes" I told him and we looked at Britney, who blushed as she looked down to the ropes.

"She do, huh?" Mark smirked, looking at me as he whispered to me "then that just gives me another reason why you should fuck me"

I chuckled at that respons and squeezed his ass, to which he yelped as he glared at me, but smiled anyway.

"Oh, I have been waiting for you to say that, kitten..."

I lifted him up and he immediately wrapped his legs around my waist, his arms around my neck as we kissed, all the way to his bedroom.

I kicked the door open and close, pushing the both of us to his bed as we broke the kiss, looking at each other as we breath slightly heavier, looking into each other's eyes.

"God, I love you...." I whispered and he blushed, giggling.

We went back to kissing, the kiss more heated as I licked his mouth, asking for entrence, to which he obliged, parting his mouth open as I shove my tongue in, practicallt mouth fucking him.

My lips made it's way to his neck, sucking and biting, leaving dark hickeys all over his neck.

I went down lower, sucking and biting where the neck met his shoulder and he let out a moan, making me smirk.

Bingo.

I continue sucking and biting on that place, making him moan and my dick getting more erect.

I sank my teeth and he let out a high pitched moan, arching his back a little.

By now, our tops were off, only left with pants. I was now on his nipples, sucking and licking one while playing with the other one

He was a moaning mess and we haven't even started the real fun yet! But I know the reason to this.

As in reading my mind, Mark whined "Dark, you know that I have really sensitive nips"

I chuckled as I looked up, meeting chocalate brown that I have loved these days. "Really? Never knew...."

Mark pouted, making him looking like a child. "Fuck you"

"Sure, in a second babe" I said seductively, making him blush as he turned his head to the side, still pouting.

I chuckled at his action, going back to do what I was doing before. I kissed down his body, earning giggles from him which encourages me to do more.

"D-Dark, st-stop! It ti-tickles!" Mark said through giggles, and I kissed all over his cute lil tum tum.

Mark giggled more, and my heart fluttered.

How could one be so fucking adorable?!

I finally stopped and gave him a littke breather, before slowly sliding down his pants, smirking at the bulge and looking at a flustered Markimoo.

"Just....." Mark said, his face all flustered.

My smirked widen, but I decided to keep quiet, taking his pants off completely, throwing it off to the side.

I took mine off too, throwing it on our heap of clothes as I climbed back on top of him, leaning down to capture his lips.

Our kiss this time were slow and lovely, love radiating through the both of us.

I broke the kiss and look down at Mark, smiling concernly.

"Mark, are you sure you really want this? I mean, it's your first time, I want to make sure it's what you want. It's your viginity after all."

Mark nodded, smiling sweetly "I'm sure, dark. I wouldn't let anyone but you take my virginity away.'

"Are you sure? Your virginity is a very important thing"

"Dark, I am sure, 100 percent sure. I'm ready"

"Are you su-"

"Yes, now stop asking and stick your dick in my glourious virginity hole"

I chuckled, pulling down his boxers, and like the rest of the fabric. I threw it at the pile, sticking up three fingers and pressing it lightly to his mouth.

"Suck" I softly commanded, and he parted his lips, sucking my fingers and I coukd feel his tongue circling my fingers. His face only wanna make me fuck him even more.

"I don't want to fuck you, Mark. I want to make love to you."

Mark grinned adorably, gently gripping my arms. "And that's why I love you"

I smile back, probably looking like a goof but I didn't care. I wad the happiest man alive.

I gently spread his legs and looked at him "this will feel strange, but it will feel good after a little while, alright?"

He nodded, and I inserted a finger, his face scrunched up so I went slowly, pumping my fingers in and out. Went he was used to it, I added another finger, doing scissoring motion, stretching his hole.

I wanted him to feel the pleasure, not pain. I want his first to be pleasurable, not painful.

When he was ready, I added the third finger, pumping in and out.

Slowly, went he was used to it, I went slightly deeper, wanting to search for that one spot. My curled my fingers and Mark let out a high-pitched moan, arching his back.

"D-Dark!" Mark moaned out, his hands gripping the bedsheets.

I took out my fingers and pulled down my boxers, my erection springing out.

Mark eyes widen as he blushed, his face flustered.

I spit on my hands rub them on my dick, making it slick up and wets it at the same time.

"Now, Mark. If it's too painful tell me,okay?"

Mark nodded, and I slowly inserted my tip in, letting Mark getting use to it, before pushing in more.

I felt Mark tensed and I stopped, looking at him as a signal to go. After a while, he nodded and I started, very slow and gently.

When Mark got use to it, he was moaning in pleasure, his head was lifted up and his mouth agape, eyes closed.

As I see Mark is okay and begging me to go faster, I pick up my speed to a normal pace, grabbing his hips.

Mark moans louder, his back arching as he grabbed the bedsheets tighter, his sounds of pleasure filling the entire room.

"Dark, pl-please, faster!" Mark practically moans out, bucking his hips.

"I am making love to you, not fucking you like a rabbit, love" I cooed, and he whined.

As I thrust into a certain spot, Mark moans loudly, his back arching more.

"Dark! Right there!" Mark screamed out and I obliged, hitting the same spot every time.

Marks' moans grew louder, and I knew he was close. I was too, and I grunted, slightly picking up speed.

Mark screamed my name as he came, and I came into him after a few thrust, lowly moaning out his name.

I pulled out off him and later and plopped down to his bed, our breathing heavy.

"That was the best first" Mark grinned, rolling his body until it was flushed against me, snuggling his face into my chest.

I lazily chuckled, wrapping an arm on his back as I pulled him closer, inhaling his scent.

There was a slight pause before Mark spoke up "what about Britney?"

"What about her?"

"What are we gonna do to her?"

I smirked and pulled him closer, snuggling my face in his floof.

"Let's not think about her now. We'll deal with her tomorrow"

So we ended up torturing her, killing her and dumped her in the furnace that Mark had in his basement and forgot about her.

So that's how we lived, two gay murdering couples, living together happily for the rest of our lives.

Whoo!

This took a while! But I'm done.
