Creepy high school #1: Slenderman X reader

5 (lemon)

Eren had invited me out to the movies and I readily agreed. I hum softly to myself as I sort through my closet for an outfit, getting dressed and adding makeup once I decide on what to wear. I pause in the mirror but my mind doesn't go to Eren. Instead, it's on Slender, my mind wandering as I wonder how I'd feel going out with him instead. It wasn't that I disliked or didn't want Eren, but Slender made me feel things no one else ever has. I've known him for a long time and I didn't want to lose him. I could only hope Eren would forgive me someday, but that would only be if he ever found out. 

I rush down the stairs when there's a knock on the door, smiling at Eren as I go to slip on my shoes. He takes me out to his car and we both climb inside, Eren giving me full access when it comes to the music. I gladly connect my phone and put on my usual playlist, singing and dancing along to most of the songs. Normally I wouldn't do this in front of anyone except my friends but I didn't want awkward silence either. Plus the more time I was left alone inside my head the more they'd go to someone else. Eren deserved my full attention when we were together, so whatever filled my brain of him the better off we'd be. I got to exit the car when we arrived but Eren insists, my cheeks blushing slightly as I giggle.

"What a gentleman," I tease as I get out of the car, accepting his hand when he offers it to me. We head into the theater, Eren checking in at the front desk as he had already reserved tickets. Once we're given the go-ahead we get concession which Eren beats me to paying. 

 "Hey! You already bought the tickets!" I protest as the transaction goes through. 

 "Gentlemen pay for their lady,"He declares as he collects the snacks while I grab the drinks.  

Neither of us see the group of four Slender brothers enter the theater but they sure see us. Slender's hands clench into fists when he sees me happy and laughing with Eren, growling when his brothers distract him. Get their food and tickets before going into the same theater as me and Eren. The two of us continue to chat quietly as we wait for the movie to start, the two of us lost in our own little world. He had picked a horror movie after I insisted I could handle it but all my friends knew I was a baby when it came to these kinds of things. It doesn't take me long to panic and hide in Eren's chest who resists the urge to burst into laughter.

"Do we need to leave early?" He teases me, my cheeks puffing into a pout as I glare at him.

 "I'm no baby," I declare, settling back down and turning my attention to the screen. It doesn't take me long to hide in Eren's chest again as he gently strokes my hair to soothe me. I'm jumpy when the movie finally ends, expecting the killer to come jumping out of the shadows. I yelp and karate chop the air when one of the attendants turns on the vacuum, my face bright red as I punch a laughing Eren's arm. "Sorry. I couldn't resist," He snickers, the two of us going back to his car. "Want me to stay the night?" 

"I am more than capable of taking care of myself. Nothing I can't handle," I tell him. 

 "If you get scared I'm only a phone call away," He chuckles, guiding my face so he can give me a kiss before I get out of the car.

I wave goodbye to Eren once I'm at the door and go inside, making sure everywhere was locked up for the night. I do open up my bedroom window while I work on homework for school, pausing when I hear something outside my window. Panic sets in and I scramble off the bed, grabbing the baseball bat I kept in my closet. 

 "Whoever is there I'm not afraid of you!" I tell, swinging my bat around the open window before I peak my head down on the garden bed below. 

 I huff when I don't see anyone or anything, returning to my school work. I scream when a handful of pebbles suddenly scatter across my floor, diving under my bed. I grab a bottle of perfume before holding my breath when someone enters the window. I follow their steps with my perfume at the ready, yelping when I'm grabbed by the ankle and drug out from under my bed. I tell and spray the perpetrator in the face with my perfume when I'm held up, my eyes widening when a groaning Slender comes into view as he wipes off his face. 

 "The hell?!" He growls in displeasure, grabbing one of my discarded shirts and using it to get the perfume out of his face.

"Don't creep around like that! You scared the shit out of me!" I snap, picking myself up off the ground. 

 "The movie wasn't even that scary!" He huffs in annoyance. 

 "Were you following me?!" I demand in disbelief. 

 "We happened to see the same movie and you two were so busy making out to notice," He huffs in annoyance. 

 "O-Oh. I guess so," I mumble in embarrassment. "So, why are you here?"

"Am I not allowed to see my secret girlfriend?" He asks with a chuckle. 

 "Never said that," I tease him with a giggle. 

 "Good," He purrs, giving me a kiss. I wrap my arms around his neck and pull him closer to me, his tongue prying its way into my mouth. I let out a soft moan as his hands press against my back, my heart beginning to race. He presses kisses down into my neck, a gasp leaving me. He presses me back and I stumble onto my bed, his body coming on top of mine. 

"Sl-Slender," I gasp out, my back arching when his hands cup my breasts.

He growls back in soft response, his hands kneading my breasts as he grinds his hips against mine. I can feel his hard-on through his pants and I knew I was a soaked mess down there myself. Our hand's fumble as we work to take off each other's clothes, my cheeks bright red as I read my hands against Slender's pecs. He gives me the chance to slowly explore his body as he gazes at mine. He's gentle when he pins my hands above my head, gently pressing his length against me. He uses my natural juices to lubricate himself before he eases inside of me. I gasp out from pain as he stretches me, my nails digging into the bare skin of his back.  

He gently rocks his hips once he's inside of me, giving me time to adjust to his size. When I give him the okay he pulls his hips back and thrusts into me once again, taking it slowly at first. As the pain gives way to pleasure I further encourage him to move faster inside of me. We come together in a passionate kiss as he moves inside of me. I cry out when he finds the special bundle of nerves inside of me, Slender focusing on that one spot. I tremble and gasp out as pleasure overwhelms me and ecstasy filled my head. Our bodies rock together until he stills, the knot in my stomach snapping as I reach my climax. Slender pants hard as he finishes as well, my insides feeling hot as his seed fills me. We both press against each other with hard pants as we hold onto the other, basking in our afterglow.
