Unedited

Dark's POV

I stealthily ran from tree to tree, peeking my head to see my senpai.

Mark Edward Fischbach.

He was the most gorgeous man I've ever seen, with his raven black hair and his auburn eyes, blocked by his round-rim glasses. An irresistible smile and laugh, his voice were like butter, smooth and deep along with his kind and loving attitude, he was basically the person everyone would want to get their hands on, girls and guys alike.

But, only I can get my hands on him, and if anyone is smart enough to even try and look at him, I'll slit their throat off.

Only two person other than me can lay his eyes, talk or even touch Mark without my permission and that's Anti and Jack.

Two lovebirds, partners in crime and both of them are good friends of mine, and they're good killers too.

Jack was always the distraction cause he looks innocent, then Anti will be the one going for the kill, and sometimes, they would invite me too.

And considering Jack and Mark are best friends, it would make things way more easier.

I grinned as I looked at the both of them and gave them the signal, they nodded, and Anti ushered Jack out.

Jack stumbled a little, but managed to regain composure, sweeping any dirt off his uniform as he called out to Mark, who turn his head as he saw Jack, smiling brightly as he walked up to Jack as they began talking and chatting.

After a while of chatting, Jack took Mark by the shoulders and switched their places, Mark's back now facing us as Jack told Mark to wait as he ran off, Mark standing there, confuse even if I couldn't see his face.

I gave Anti the signal and he nodded, coming out of the bush and tapping Mark's shoulder, to which Mark turn around and his eyes widen, looking back to where Jack ran and then back to Anti.

Yeah...Mark doesn't know that Anti exist.

Anti offered him a drink and did his best Jack impression, which was perfecto, and Mark smiled, taking a big chunk of the drink before giving it back to Anti, who was trying not to smirk but gave Mark a smile.

I felt a presence behind me and I turned around, seeing Jack looking at me with a thumbs up and I gave him back the thumbs up and we look back at the scene.

Mark was soon wavering, struggling as he tried to stand straight. His eyes were fighting to open, and at last they close, and he fell, but Anti got him by the armpits, dragging him back to where Jack and I were.

"Good job, Anti." I grinned as I looked at mark unconscious form, then to Anti who mocked a bow, tipping his imaginary hat.

"No problemo, mi amigo"

I rolled my eyes, shaking my head but I smiled nethertheless, looking at Jack who was giggling quietly.

"C'mon, we have to hide Mark before other people sees him"

Le time skip-

Mark's POV

I groaned as I woke up, blinking as I adjusted to my surroundings, realizing that I was tied to a wooden chair.

I blinked a few more times before rising my head, and the first thing I noticed was a pile of green hay on someone's head.

Jack

He was looking at me, smiling.

"Oh hey, Merk. You're awake, took you long enough.." Jack smiled at me, but I didn't smiled back, still confused and a little afraid.

"J-jack?" He hummed, "W-where am I and w-why am I tied up to this chair and-" Jack shushed me, putting a finger to my lip before taking it away.

"Okay Mark. I know you have a lot of question but one at a time please..." He looked at me, gesturing me to ask and I did.

"Where am I?"

"Your in a basement..."

"Why am I tied up to a chair..?"

"Because you are....?"

"Your not answering my question, Jack."

His smile flattered and he sighed, pinching the bridge of his nose.

"Look, Merk. As much as I would love to tell you what's going on right now, I can't. I'm ordered to give limited information"

I looked at him then scrunched my eyebrows, realizing something.

"Why..are you here then?"

Jack raised his eyebrow as he grinned, looking at me.

"Oh nothing, just here to help a friend.."

You know, even if I'm tied to a chair and Jack is not helping me get out of here, I still can't help but joke around with him.

"But Jack why? I thought we were friends...?" I said dramatically and Jack snorted, rolling his eyes as he grinned.

"Top ten anime betrayals be like..." Jack trailed off as I let out a little giggle.

"Oh yeah, by the way, Jack...I have another question to ask you..."

He nodded, gesturing me to continue.

"Okay..so as far as I can remember we were talking and you suddenly lured me to my death trap by switching places and you ran away and a second later you appeared, like how?"

Jack raised his eyebrow before smiling, a tint of red on his face.

"oh that? Well uh...." Jack trailed off, looking off to the side as he puffed his cheek.

Now's my chance to make him a ball of embarrassment.

Cause that what friends do.

"ooo, what is it that your not telling your best friend, hm?" I taunted, smirking up at him.

He blushed, looking off to the side, his cheeks red and puffing.

We were like that for a while, with me constantly taunting Jack and making him a redder mess every single time.

And as I was taunting him and making him a blushing mess, the door opened and I stopped, raising an eyebrow and looking at the door.

A figure walked in, and I furrowed my eyebrow, looking at the figure.

Whut?

The figure looks exactly like Jack!

There were only slight differences though, like, his hair is a dark green instead of Jack's coffee brown hair, gauges, a slice through his neck and he somehow managed to survive, with dry blood dripping down.

He walked until he was beside Jack as he slung an arm around Jack, pulling him closer and Jack squeaked, face burning as the man kissed Jack's forehead.

My eyes widen as I looked at them, my mouth agape, puzzling all the pieces together in my head.

Jack looked at me and his smile flattered, looking almost scared as he avoid eye contact with me.

"I-I know t-this lo-oks we-ird to you...a-and it'-s alright i-if you d-don't wanna b-be my f-f-riend after th-is..." Jack stuttered and I looked at him, smiling.

"Jack. I don't care what you are, Gay, Trans, or whatever. I will always be there for you, no matter what. Plus..." I looked at the dude "....you guys looks absolutely adorable...."I smirked as I looked at Jack "...plus, when are you guys going to fuck?"

Jack look wide eyes at me as his face went red, slapping my arm in a playful waywhile the Jack look alike just smirked. "Merk! Oh my god, how can you say that!" Jack shouted and I chuckled, flinching from his hits.

After a while, we stopped, and the Jack look alike looked at me and smiled, Jack by his side.

"I'm happy that you support our relationship. Jack has been wanting to tell you for a while now but was always afraid. But I'm glad that's all over now."

I smiled at him "Hey, no problem.....?" I looked at him, forgetting that I didn't know his name.

"Anti. I'm Anti" He introduced and I nodded, smiling.

"I'm Mark, but you already know.."

I then looked at Anti questionly. "Were...you the one that took me down here?"

Anti shook his head, chuckling "No. It wasn't us. We were just helping"

"Who..?"

"A friend of ours, he was head over heels for you ever since he first landed his eyes on you. He wanted to admit his love but was always too afraid to admit it. So....we did the second most optional thing and that's kidnapping you...so..be nice to him, alright? He may look strong, but his very vulnerable when it comes to you. So...one wrong word and it may ruin his whole will to live."

Wow, okay.

I raised an eyebrow and slowly nodded, looking at Anti.

"....and...who is that...?" I asked slowly, watching as Anti grinned, shrugging.

"you'll find that out yourself." Anti smirked, slinging an arm around Jack's shoulder as they started walking away. Anti turned his head and looked at me, still smirking "..besides, it's not like you guys never met before.."

Whut?

I watched as the two lovebirds walked away, Jack closing the door behind him not after warning to be careful around him, I nodded and he smiled, winking at me not before saying

"I'm sure you guys will get along quite smoothly..." was all he said before the door shut completely, leaving me in square one all over again.

I was quite curious....who is this man that so in love with me? How does he look like? And, have I really seen him before.

Well, whoever he is I'm sure his a shy person if Anti and Jack had to kidnap me just for me to meet him.

Dark's POV

I looked at the trembling girl before me, smiling deviously as I licked the blood off the knife of another girl that I had killed previously and didn't even bother remembering her name.

I looked down at the trembling girl before me, my grin growing wider.

I know this girls name, because she was the one that always tries to take Mark away from me.

And the worst part about it? She knows, she know that I loved him and she still chase after Mark like the slut she is.

So, here she is now, trembling before me.

"You know.." I started, "...if you knew Mark was mine......then why did you still try and take him away from me..?" I said, fake hurting laced in my voice.

The girl, known as Susan, looked at me with an almost angered look, as if I wasn't about to kill her and we were having a normal conversation.

"So...Your doing this all for Mark?!" Her voice raised higher at each word, and literally shouting Mark's name.

I did not flinched, unfazed by it. I looked at her emotionlessly, and she slightly shrunk at my gaze.

"Do you wanna know why I did this? Susanne?" I asked, taunting her.

"It's Susan, and no! I don't wanna know why you did this!" She screamed, but I didn't flinch, continuing looking at her with an unamused face.

"Well, your going to know anyway.."

I trailed a the knife down her cheek, and I could feel her trembling madly.

"Well,if it isn't obvious enough, I love Mark, I love him with all my heart. And I would do anything for him" I leaned in close to ear, whispering lowly "and I mean anything...."

"So it's that why your doing this?! All because if your love for Mark?!"

I leaned away from her, looking at her fearful eyes.

"Yes. Because Mark is my senpai..." I chuckled a little, knowing that what I'm about to say is something Mark used to say.

"...And I love Senpai, yes I do, his for me...." I leaned in into her ear "...Not for you..." and with that I stab her in the stomach, watching as she gagged as she struggled against my hold.

I watched as the life left her eyes and her struggling got weaker, looking at me the entire time.

Sooner or later, she stopped struggling ad she stayed still, her now glazed eyes looking at me as her mouth was slightly agape.

I took my knife out of her and she fell limp to the ground, a trail of blood on the wall.

I grinned, licking the blood of my knife, humming at the taste.

I looked at the dead body that was in the room, signing after that.

Five bodies in total, blood everywhere...I have a job to do.

As I was thinking about how to get rid of these bodies, the door opened and I snapped my head to the side and smiled when I saw that it was Anti holding Jack close by the waist.

"Done?" Anti asked, a smirk on his face as he scanned the room.

"Done" I replied back, looking at them.

"His waiting for you, I'm sure his curious to know who you are. But change your clothes, down want a bad impression~" Anti sang, and I rolled my eyes, walking to the door.

As I was walking out, Anti took my shoulder as he whislered in my ear "don't be nervous, Dark. I'm sure you'll do great."

I just nodded as I walked out and Anti called back out to me "And we'll clean all this mess, so don't worry!"

I raised my hand and did a thumbs up, walking to my closet as I changed my clothes, looking at the mirror as I floofed my hair.

Here goes nothing.

Mark's POV
I started at the door, my curiosity getting the better of me at finding out who the hell that person is that I was literally begging to god for that person to come faster.

I sat there for a little while longer, just wondering who it was and my question was answered when the door opened, revealing a built figure, a figure even more built than me, so it was pretty obvious that it was a guy.

The figure walked in, and I could sense the nervousness in his steps, and when the figure walked close enough, my eyes widen.

D-Dark?!

Dark is in love with me?!

What?!

I-i thought it was suppose to be the other way around.......

I was frozen, looking at Dark with wide eyes, taking in his features.

His scarlet eyes that shone nervousness, the way his hair was messy but it looked cute in him, he was wearing black muscle shirt and black pants.

I was flabbergasted, Dark love me?!

I am out of words to say, like literally.

"D-Dark.....?" I finally said, my voice laced with obvious confusion and surprise.

Dark eyes widen as he looked at me, like he was surprised that I knew his name.

"Y-you know m-me?" Dark stuttered, and I haven't realized that the both of us were blushing, me blushing more than him.

I just nodded, still looking at him wide eyes.

"Y-you l-love m-me?" I slowly said, still stuttering and his blush darken, nodding as he looked down on the ground.

"I thought it was suppose the other way around......." I muttered softly but Dark heard it, looking at me with wide eyes

"Wh-what....?"

I keep an eye contact with him as hard as I can, decided that explaining to him will be the best.

"W-well...." I started "..I-I first saw you in one of our classes, you were sitting in the back seat, focusing in class, and.....And I fell in love with you?" I raised my pitch in the end, my nervousness getting the better of me.

Dark was looking at me speechless, his face unreadable before leaning down and kissing my forehead gently.

I squeaked, slightly jumping as my face was back to square one, red as a tomato.

Dark smiled, and my heart basically fluttered out of my chest.

He leaned down again, this time to undid the bonds and threw it to the side.

I stood up and my hands was around his waist, pulling him close to me as I buried my face in his chest, inhaling his scent.

He wrapped his arms around me, a hand went up to pet my hair, and I snuggled deeper into his chest.

"You know, if I knew you felt the same way, I wouldn't had to stalk you."

I giggled,looking up at him, booping his nose "yeah you wouldn't. You look really weird."

Dark grinned, pecking my forehead again and I blushed, biting my lips.

"Your so adorable, Mark. Sometimes, I just wanna get out of my hiding place just to pinch your cheeks"

I blushed harder, and Dark tilted my chin up with his finger, making me look at him.

His eyes went half lidded as his eyes flickered to my lips and back to me, leaning down as he tilted his head slightly, capturing his lips in mine.

My eyes went widen as I let out a muffled squeak, but eventually gave in, closing my eyes as I kissed back.

Dark pulled me closer, one hand was wrapped around my waist while the other was gently weaving through my hair.

We parted for air and we looked at each other, smiling at each other as our breathing was heard.

"Wanna take this upstairs?" Dark suggested and I nodded.

I squealed when Dark grabbed me by the waist as he lifted me up, my legs wrapped around his waist and my hand around his neck as he chuckled, leaning closer as we continued kissing.

We kissed until we reached his bedroom, only parting for a breath before going back to kissing again.

Dark opened the door and kicked it close once we were inside, slamming it shut.

We kissed until we reached Dark's bed, and he gently laid me on his bed.

"I never thought I'll come to this day....." Dark muttered, kissing down my neck slowly.

"M-me t..too" I stuttered, tilting my head to give Dark more access.

Dark slid both his hands under my shirt, roaming his hands up and down my sides, making me shiver as he took my shirt off, throwing it somewhere as we continue kissing.

I tugged on his shirt, and he chuckled, taking his shirt off as well and throwing it to the side, going down to my chest as he began sucking on my sensitive nipples.

"A-ah, D-dark!" I mewled out, slightly arching my back.

Dark chuckled, his breath hitting my nipple making me shiver.

"So little Marky is a kitty, huh?" He taunted and I huffed, sticking my tongue out at him.

He smiled and responded with licking my tongue and I squeaked, retreating my tongue back as my face was back to being a tomato.

"I've noticed you squeaking a lot recently, are you actually a squeak toy in disguise..?" He asked and I huffed, looking to the side as I puffed up my cheeks.

"Well, I think your more cute when your mad.." My eyes slightly widen as my cheeks became hot again, putting my hands to my face.

"Don't hide your face away from me, senpai"

I felt my hands being removed from my face as Dark pinned my hands up above me with a hand, another hand grabbing my chin as I looked up at Dark's mesmerising red eyes.

Before I knew it, we were back to kissing again, the kiss started out slow and loving before it went heated, including more tongue.

After a while of Dark roaming my mouth he went down to my neck, leaving love bites everywhere, determined to find that spot of mine.

A moan left my lips as he founded it. I tilted my head as he sucked and nibbled on my sweet spot, leaving a darker mark then the rest.

Dark then went down to my chest, leaving trail of kisses as he went down to my nipples, and like before, he went to sucking on one and playing with the other.

I slightly threw my head back, my mouth agape as I let out a soft moan, mouth agape as my eye were shut.

Dark hummed, trailing his mouth down to my tumtum after a little while of sucking my nips, leaving kisses.

I giggled softly, Dark's mouth tickling me as I looked at him with an eye closed. Dark looked up at me with an eyebrow raised, smiling as he leaned up and kissed my forehead, making me blush, before going back down to my tummy.

He reached down to my crotch as his breathing was hitting my clothed erection, making me shiver in the slightest.

"We don't need this now.....do we..?" He seductively mumbled, his voice lower as he looked up to me and grinned.

Before I could even blink, my pants were off me and thrown to the pile and I looked at Dark who just smirked.

I was only now left in my boxers while Dark still had his pants on and I whined, mentioning to his pants.

Dark got the idea and chuckled, looking at me.

"What an impatient little kitty you are, aren't you?" Dark smirked in the slightest, his eyes shone mischievousness. (I feel like Dark is being so ooc as a yandere oops)

I blushed and Dark chuckled, getting up as he got out the bed and he looked at me, smirking.

"Don't move.." He said before turning his back on me, walking to his set of drawers, humming.

He soon came back with a something in his hand, and I immediately recognized it as a lubricant, climbing back on top of me as he grinned, pulling me into a kiss.

I instantly kissed back, not noticing that Dark had popped open the lubricant and coating his fingers with it and taking off my boxers until I heard fabric tearing.

I looked at Dark and pouted "those were my favourite" I mumbled.

He chuckled softly and kissed me by the forehead "I'll just get you a new one, Senpai.."

Before I even had the chance to answer, Dark slipped one of his fingers into my hole, instantly shutting me up.

I slightly hissed in pain, and Dark comfort me, another hand went up to my hair as he slowly stroke it.

"shh, it's going to be alright.." Dark comforted, his voice soft and caring.

I nodded and he started pumping it in and out slowly, adding a second finger after a while.

He started stretching me out as he keep comforting me, continuing stroking my hair lovingly.

When I was stretched enough, he added the third finger, pumping in and out at a normal pace.

The pain was subsiding and so were my hisses, the hisses turning into a moan.

Dark smiled as he took his fingers out, getting out of bed to take off his pants and boxers, his erection springing out as I blushed madly.

That is the biggest thing I have seen on a human body, alright.....

Dark went back to the bed, squirting a generous amount of lubricant on his dick before taking my legs and hooking it to his waist.

"I-I can't f-fit that m-much.." I whimpered out, and Dark shushed me with a kiss to the forehead.

"It's alright, I'll stop if you can't, alright?"

I nodded and motioned to him that I was ready, and I could felt the tip in my hole.

He slowly slipped in, and I hissed, clenching my fist as my eyes were screwed tight.

He was soon inside me whole, without me realizing it and he was just waiting for me to make the signal.

The pain subsided, and I looked at Dark with an opened eye.

"G-go" 

Dark nodded as he slowly slipped out until only his tip is in before inserting in again.

He was gentle and slow, not rushing it as he sent me comforting words while pulling it out before inserting it again.

After a while, I got use to the pain and I was starting to moan, my back arched as I mewled pathetically.

Dark smiled as he speeded up his thrust to a normal pace, holding my legs as he did so.

I was a moaning, writhing mess. Moaning and mewling Dark's name like a porn star.

Dark was a hot mess, groaning softly as he pounded into me, his hair sticking to his glistening forehead because of his sweat.

A few thrust later, I felt a pool formed in my stomach and I knew I was close, Dark could felt it too because he went a little more faster.

"D-dark, I-I.."

"Come for me, Senpai.."he muttered lowly, and that was all it took for me, screaming his name as I came.

Dark came inside me with a low groan, filling my stomach with warmth.

He pulled his dick away from my hole as he cleaned us up, plopping beside me as we snuggled up.

"See, Jack? I told you they would fuck a hundred percent." A glitchy voice suddenly sounded, and the both of us sat up to see Anti and Jack in the hallway. My face instantly heated up.

"Anti! Jack! What the fuck are you doing here?!" Dark shouted and Anti smirked, wrapping an arm around Jack.

"We betted if you guys were gonna fuck.." Anti slyly said as he looked towards Jack, who was a blushing mess as Anti leaned into Jack's ear "...and looks like I won the bet.."

Jack huffed as he pushed Anti, pointing a finger at him.

"For clear clarification, they made love. They did not fuck.." Jack stated as a matter of fact

"It's still counts as fucking for me.." Anti shrugged and Jack shook his head.

"Okay, would you two loud assholes get out before I throw you guys into the fucking basement?!" Dark voice boomed and the both of them walked away, not before Anti pointing the middle finger to Dark before pushing Jack away as they ran, shutting the door.

Dark and I laid in bed again, with me snuggling up to him and him wrapping an arm around me.

"Are they always like that..?" I softly asked and Dark softly sighed, pulling me closer to him.

"Yes. But mostly Anti. He is the biggest asshole you'll ever know in this house.." Dark rolled his eyes but smiled, looking down at me "...but his a good friend.."

He kissed my forehead and I softly giggled, snuggling up to him.

"All I can say is...welcome to my crazy family.."

I lazily smiled as I wiggled a little to get comfortable, not before wishing Dark goodnight to which he replied back.

My eyes soon began to drooped, and the last thing I felt was dark kissing my forehead again before I felt asleep.

"Mine...till the end.."

Okay, so this took a while, wow.

I decided to take a different approach to this AU and I hope you guys liked it.

If not then IDK.

It's probably because that maths and history exams fucked me in the brain so hard that I need a new one.

Eh.
