Tears brimmed and threatened to slip from your eyeline. You were finally standing in front of it. It being the gigantic three-story Victorian style home you had been dreaming about for almost a whole year. After spotting it in a listing while surfing for homes, you instantly fell in love with it. It was old but said to be in good condition. Though it had gone through several owners in the span of five years, you paid it no mind.
It's siding was a calming sage green. The trim a deep black that followed the rails and fencing on the spacious porch that wrapped around to the side. The darker color followed to the spindles and the narrow windows on the asymmetrical façade. You gasped at the splendid tower that perched on the roof. Your eyes tried to take it in all at once, like a shot of something. It hit you quick and stayed with you for a moment.
You gazed at the third floor windows once more. The black panels held a thick crisp glass. An eerie sensation washed over you. A chill flushed down the back of your neck and your eyes darted away from the third floor.
“Hey—”
You nearly jumped out your skin, “oh—shit—Eren you scared me!” You turned to one of your best friends. He held a box of your stuff. His long hair was pulled back in a man bun and he sported a black flannel. It brought out the green in his eyes.
“Sorry! But I was getting tired of watching you lovestruck over architecture,” he shrugged and marched towards the door of the house.
“Wait! I want to be the first inside!” you raced to the door. He took quick strides to beat you, all with a heavy box of kitchen supplies in his hands. “ren no fair! You have longer legs than me!” you pushed him out the way.
He laughed, “I wasn’t getting in there, you had the key princess,” he leaned close while you tried to put the key in the hole, “though I appreciate the compliment.”
That earned him an eye roll. You pushed the black painted door open. It squeaked with a heavy groan. Fading sunlight creeped through the windows, providing you enough natural light to roam around.
“Damn you keep the curtains open, you’ll never have to pay a light bill,” Eren followed your gaze to the wallpapered foyer. It had a grand entrance that then led to stairs and several other dark brown oak doors. The kitchen remained open, with just door trim guiding the walkway. The living room had a door to it. You walked into the kitchen which was closest. Eren the box on the island. The cabinets had the same dark wood as the doors, which added to the old feeling of the home. The wallpaper was the same as the foyer. A light cream color with watercolor green roses. Specks of brown flowed through the paper from the traces of loose rose branches.
All your furniture was in the kitchen already, thanks to the moving company. It wasn’t much but all your furniture had been transferred out of your apartment. So, you had been sleeping in Eren’s spare bedroom, only vacant because his roommate, Jean, had pissed him off. You were excited to sleep in your own bed once again.
You both moved onto the living room. Upon opening that door your eyes widened. Your furniture was straightened out and put together. Only thing untouched was your knick knacks and photos.
“Did the movers clean too? I haven’t seen even one speck of dust and it’s been almost a week since they brought all this stuff,” Eren ran a finger over your glass coffee table.
You slapped his hand off it, “well now it has a greasy fingerprint on it,” you pursed your lips at his boyish grin, “and I don’t know. I’ll have to leave a stellar review! They positioned my furniture for me!”
Eren scratched his arm, “eh—well how’d they know you’d want it that way?” You kept walking to the other side where the downstairs bathroom was. It connected to the main foyer as well, in jack and jill manner.
“Hmm, not sure, I did leave some floor plans with an outline of potential arrangements in one of the boxes, they might’ve found it and been extra nice.” The two of you went around the house, eventually getting upstairs to the bedrooms. It was a four-bedroom home, the main bedroom being yours and you hoped that friends and family could fill the others one day.
Everyone was against you buying such a large house, but it was too beautiful to turn down. You had been saving up for a house for a while, and when this one popped up with such a low payment, you couldn’t resist. It called to you like a siren in the sea. For months you obsessed over it, getting everything in order to be able to get it.
The two of you got up the wooden stairs, they creaked with almost each step. Just another sign of the house’s age. The long hallway had doors on each side of the wall. A brown door was at the very end of the hall. “That’s the door to the third floor, or what the reviews called the attic.” You pointed to it, “it’s one of the reasons why the deal was so good, no one can get the door open.”
“pfft, it’s not steel, just kick it down, or better yet, unscrew the hinges.” He faked kicking a door in.
You rolled your eyes at him once more, but a small smile formed, “it’s basically an attic, not much up there besides dust and cobwebs.” You started towards your room which was one of the first doors to the left, “though if I need extra storage I’ll try.”
“Wonder if there’s a dead body up there,” Eren snickered.
“Eren!” you pushed him, “why would you say that!?”
He fell against the wall, laughing, “c’mon it’s just a joke.” You shot him a glare with your arms crossed, “not a very funny one. Why don’t you go explore or something.”
With a shrug, he went down the opposite side of the hall. The one that housed the study, and washroom along with the hall bathroom. You went into your bedroom. Your furniture was set up in there as well. Your bed, shelves, and dresser were all in the room. Your bed wasn’t made, but you didn’t mind. You glanced in the bathroom, still wanting to explore more later.
Your curiosity nagged at you. It tugged at the sleeves of your brain to try the door at the end of the hallway. With soft steps, as to not alert Eren, you made way to the brown door. It had slightly different paneling. While the rest of the doors were six panel, this one was only four with them being long rectangles. The knob was gold, but it was tarnished with age. You tugged on it, but no budge. You huffed and took a step back. You pushed on the door to no avail. It felt like something was blocking it from the other side. Or someone. Your heart raced. You pressed your ear to the wood, praying you wouldn’t hear anything. Your eyes shot open in. Your face flushed of color. The unmistakable sound. A single breath.
“Boo!”
You screamed louder than you’ve ever scream before. It hurt, your words were lost in the back of your scratchy throat. You mustered a wimpy slap against Eren’s chest. Your other hand clutched your rapid heart. “you fuckin’ asshole.” You croaked. Eren doubled over, clutching his chest with a howl.
“I’m gonna kill you,” you pushed past him.
Eren grabbed your arm, still laughing, barely able to catch your sweater sleeve. “Oh c’mon, you gotta admit I got you good!”
You shook your head, shrugging him off, “you’re such a jerk. Scaring me in my own damn house!” Tears started to brim, and your chest got tight. The slight wobble of your bottom lip was a dead give away.
“Hey,” Eren said softly, “hey I’m sorry, I didn’t know it would freak you out like that.”
You wiped away the stray tear that fell, “I’m just—it’s just a lot. I don’t know why I got such a big house for just me. I guess—I’m just kind of scared.”
“If it makes you feel better, I did promise to stay the night with you. This is your dream house, don’t let anyone take that from you.”
You sniffed with a nod, “can you make me hot chocolate?”
He rolled his eyes with a chuckle, “sure, but I get to pick the movie we watch.”
Your lips quirk, “deal, but nothing too scary, I still have to live here after you leave.”
The night went smoothly and the next morning Eren left. You were truly alone. The emptiness of the house dawned on you quickly. It helped that you were gone most of the day at your job. It sucked that it got dark soon after you’d get home. For the first week, you turned every light in the house on and left them on until you went to bed. Yes, you knew how much that killed your electricity bill. It gave you a sense of comfort. Then soon you had a routine.
If all lights were on, you’d start from the ground up. Living room, kitchen, foyer. You rarely set foot in the den, so you didn’t have to worry about going into that corner of the downstairs. Then you headed upstairs, which was the easiest. You didn’t use the spare rooms or the study, so it was just the hall light. It was tricky though; there were two switches to turn the hall light on. One was near the steps, and the other was closer to the end of the hall, near the 4-panel door. Your room was near the middle. You only used the one near the steps, but the electricity was faulty. Sometimes the light wouldn’t turn on or off. When that happened, the hall light stayed on. The door at the end of the hall froze your arm hairs in place, and sent cool shivers down your spine. You could barely stand looking at it.
“Yes mom, I know,” you tucked your phone under your chin and shoulder while you fumbled with your keys. Finally you opened your door with your hands full of Chinese take out and files from from work. “Yes,” you mumbled. Your eyes couldn’t go back far enough from the lecture you were getting.
“I’m just sayin’ sweetie, it’s not good for a gal to be alone—and in the woods nonetheless.”
You sat your take out on the stove, “it’s not the woods mom, there’s a house less than half a mile away. Sheesh you act like I’m in pure wilderness, it’s only a thirty minute drive to the city,” you put her on speaker, tossing your phone on the counter. Your brows furrowed. The coffee stain from the morning had disappeared.
“Sweetie, are you there?” Your mom questioned.
“Uhh—yeah mom umm let me call you back actually. Love you! Bye!” you hung up. You remembered dropping a splash of coffee on the counter before you left for work. Were you imagining things? You shook your head. You had to be, you could’ve cleaned it during your morning rush out the door. Yeah, that was it, you cleaned it before you left. Right? You sighed and pulled the styrofoam container out of the bag with a smiley face and THANK YOU written three times on the side.
EERRK. Your head snapped up to the ceiling. The creak was heavy, in tandem with a boot. Your heart pounded against your chest. Your mouth suddenly dry and tasting of stale coffee. You waited, ears perched and body unmoving. It didn’t come again. You let out a breath that you didn’t realize you were holding. “It’s just the house settling,” you took a bottle of wine out the fridge, “nothing to be worried about,” you took a long swig. The cheap liquor burned, “yeah, that’s it, I’m fine!” you chuckled. You gathered your food and the wine and trudged to the living room. You got wine drunk fast. Preemptively falling asleep on your couch.
You woke up with the sudden urge to pee. You threw your blanket off. Wait, where’d the blanket come from? You had to pee too bad to care. Oh that’s right, you had a blanket slumped over the couch. When you’re drunk you barely remember what you’re doing in the moment. You went back to sleep on the couch. You told yourself it was from laziness, but in the back of your mind you were terrified the house wasn’t shifting.
The rest of the week was the same, come home, drink, pass out on the couch. You only went upstairs to take a shower and dress. You came home early on your Friday. It was still light outside, the sun went down slower and left an orange glow. It had been raining all day, so the appearance of the sun made you happy. You spent time in your reading nook upstairs. You drank some tea, even put on some soft music and started on laundry. By time you did all that it was dark. It had also started to storm again.
You planned on sleeping in your bed for the night. Your back was in need of a rest from the couch. You started your routine the same, living room, kitchen—then blitz of lightening blazed in the kitchen window, followed by the roar of heated thunder—killed the power in your home.
Your hands flew to your phone faster than the lightening outside. You pulled up your flashlight, checking your surroundings. You were grateful for the cheap candles you had gotten for a gift one year. You found your lighter in the junk drawer. You lit the candle and left it in the kitchen. That would be your home base while you tried to find your fuse box.
You called Eren, hoping he’d answer, “Hello,” he answered groggily.
“Eren, I’m scared, my lights went off a—and it’s so dark in here”
“Woah, calm down—the storm probably knocked the power out,” there was a long silence, “listen, go to sleep, by time you wake up it’ll be morning and you won’t have to deal with it, okay?”
Your heart dropped, “Eren I’m really scared. The house has been making strange noises and weird shit has been happening. Can you please come over?”
You heard the ruffle of bedsheets, “I’m kind of tied up right now, I’ll be there in the morning I promise. I gotta go,”
“Eren!” you fumed, “you asshole!” you hung up. You could do it for the night. All you had to do was make it through the night.
You crept up the stairs, holding yourself close to the railing. Your eyes immediately darted to the door at the end of the hallway. Sweat made the grip on your phone unsteady. You trembled. The door was open. The dim phone light barely met to the end of the hall, yet you could faintly make out what looked to be clothes. A blood curdling scream ripped from your throat. It came closer and you stepped back once. You kept screaming. You had half the nerve to throw you phone at it, but opted to race down the stairs.
A tragic misstep on the final step sent you faceplanting to the ground. You groaned and turned over on your back.
There was a disapproving grunt and then a man’s voice, “damn brat,”
You passed out. From what? You’re not sure, probably the man in your house during a blackout, but you came to in a large room. You grabbed your surroundings, only to find plush sheets. The lights were dim. It had the same wallpaper as the rest of your home. You squinted, “oww.” You grabbed your head and sat up.
“I wouldn’t do that, you could have a concussion,” the man’s voice from the darkness forced a flinch from you.
Your heart started pounding again, “who are you?” Fear etched you voice with a lace of curiosity. You didn’t feel like you were in immediate danger. There was a sense of relief and calamity. Almost like this was normal.
He stepped into the light, but only a slight shadow was cast from his clothes. Then a picture frame landed in your lap. Hesitantly you picked it up. It was a photograph of a man in what seemed to be his early 30s. He was unsmiling, but with handsome features. Sharp eyebrows that added to his cool gray glare. With short black hair that had an undercut to it.
You traced a finger down his pictured cheek, “you’re beautiful.” There was a short pause before you spoke again, “what happened to you?” your voice was small as if you’d whispered a forbidden secret.
“Tch, you’re a nosy one aren’t ya,” he grumbled.
You sank back into the bed—his bed—that he’d been sleeping on—in your house. “You’re in my house! I think I have a right to ask some questions.”
“Ugh nosy and noisy. Fine, I can’t tell you what or why, only that one day almost five years ago I woke up and was like this.”
“So you aren’t a ghost?” you interrupted.
“Then I—no, I’m just invisible.”
“Was that sarcasm?”
“Did it sound like sarcasm?” You saw his sleeves cross, understanding he was refolding his arms.
You shrugged, “coming from you it did.” All the fear had seemingly drained from your body, “are you always this grumpy?”
His arms tightened and his body turned away from you, “I’m not—grumpy.” His monotone voice carried a sense of annoyance, “besides it’s my house, I sold it, then watched those disgusting pigs fill it with trash. I don’t tolerate filthy behavior, you’re the first not to run away. Are you an idiot or something?”
You chose to ignore his insult, “It was you—you cleaned my spill,” you got off the bed, “did you rearrange my furniture too?”
He scoffed, “couldn’t have you or that dumbass you brought with you scraping the floors.”
You nodded with an agreed shrug. “Does that mean you also put the blanket on me?” It was a dumb question, you knew the answer, but you wanted to hear him say it. You’d taken a liking to his short tone.
“You could catch a cold,” he sat down in the chair in the corner. His legs crossed based on his pants legs folding over the other. He leaned his head on his hands. It was odd. You felt like you could see him. “Don’t make it a habit, I’m not here to babysit a drunk.”
You rolled your eyes, “why are you here then? I mean if you sold the house, why not leave?” Silence filled the spacious room. You took time to look around more. He had his own bathroom, refrigerator, and stove. His own little apartment. Everyone said this floor was just attic space, but the tall triangular ceiling held more.
He remained silent until you crossed the room. “It must’ve been very lonely,” you eyed his antique tea cups on the shelf by his chair.
“You get used to it,” he mumbled. “All my friends are—gone, the house—it’s all I have.”
You stood in front of him and then kneeled down, “you don’t have to be alone anymore,” you smiled and took what you assumed to be his hand, “I can be your friend.”
You were either a complete idiot or lonely yourself to allow a strange invisible man stay in your home with you. You could’ve been pent up from thinking there was a ghost in your house the whole time. Or perhaps you were naive enough to think you wouldn’t fall for him. Though, you found yourself in that exact situation. You gave it a month. You honestly didn’t expect it to happen so soon, but Levi, as you learned, opened up faster than you thought. Just enough for you to find his rough tone to be cute, his teasing remarks were hot when they caught you on a good day, other days you found them to be amusing. He could be amusing even though his quiet demeanor and reserved personality made it hard to connect sometimes.
You think he’d taken a liking to you as well. Keeping the house clean while you’re at work, even reading with you in your reading nook. He spent more time out of the attic, watching movies with you and making you tea. It was nice to have another person in the house.
Eren never came the day after the power outage, not that you needed him to, but he did come over that week. Every time he came over something creepy would happen, something only out of a horror movie, something only Eren would see, but strangely enough you never cared.
“There’s a damn ghost in this house <3 I swear!” Eren hid behind you as you opened your front door. He was damn near on the back of your heel. “Do you not see that shit?”
You hid the smirk that wanted to spread, “the house is fine Eren, stop trying to scare me.”
“Scare you?! Girl! I saw a candle floating at the top of your stairs!” He licked his lips, nervously looking around, “and how the fuck do you explain your microwave turning on when we’re both in the living room?”
You shrugged, “it’s an old house, it does weird things,” you sat your stuff on the hallway table in the foyer.
Eren shook his head, “there’s a damn spirit in here, you need to leave, please, I want you to be safe,” he held your arm.
You smiled at him, grateful that he did care enough to be concerned. You kind of felt bad. You didn’t realize how much Levi disliked Eren, but you found it hilarious that he played with him like that.
You found out just how much he hated him when Eren was begging you to leave the house. It’s like some sort of possession occurred and Levi turned into something akin to an angry spirit.
He followed you into your room after seeing Eren out, “are you seriously going to entertain that?”
You stifled a laugh, “Eren just wants what’s best for me—am I sensing fear?”
“What the hell do I fear?” he huffed.
You crept to him with a smirk, “oh I don’t know, not having me here,” you poked what you thought was his nose.
“That was my eye,” Levi groaned, “and I don’t fear that, because you’re not leaving.”
Your smirk widened, the gap closed, “yeah? Why’s that?”
Levi had a way with his actions more than he did his words. Another thing you learned quickly from the invisible man. Being tossed on your bed out of nowhere had you dripping. It didn’t take long for your clothes to be torn off and him in between your soft legs.
“He’s a fuckin’ dumbass,” he muttered as he slipped a finger into your soaking heat, “can’t even tell the difference between a candle and a candelabra.”
You moaned, head falling back, “h—he means well.”
“Calling me a damn ghost, a ghost couldn’t touch you like this,” he kissed the inside of your thigh. It was odd feeling his lips against your skin. You couldn’t see him, couldn’t see his pale pink lips ghosting over your soaked core, or see his two fingers dipping into you, “stop defending him,” he smacked your thigh.
You could only imagine his gray eyes raking over your body, how his face scrunched in irritation. It was frustrating, not being able to see his beauty, “focus on me, on my touch,” his voice cut through your thoughts. Like he was in your head, he latched his mouth to your folds. You cried out, fisting your pillow, “o-ooh,”
His mouth was skilled, his tongue took the place of his fingers, lapping your juices into his mouth. You didn’t expect him to be so messy, but he went deep, his nose bumped your clit. Little whimpers fell from your lips as your climax built. He pulled back slightly, just to spit on your cunt, “’s good,” then he was back to his feast.
He grabbed your hand and placed it on top of his head. His hair was soft between your fingers, and you tugged hard on the invisible strands, “oh shh—shit p-please,” you chanted. He groaned against your pussy, swinging his face back and forth over it. You came with a harsh tug to his hair and a chant of his name.
“You’re so perfect cumming on my face,” he detached his face from you. Slick covered his see-through skin. You could almost make out lips and his nose. He wiped his face with the back of his hand. He sat on his knees, unbuttoning his shirt one button at a time. “Can you give me another?”
You nodded breathlessly, “yes,” you pinched your nipple between your fingers. You watched as he undressed himself until you couldn’t see him anymore. His clothes defined him, they told you where he was, his height, his physique. Everything you knew that he didn’t tell you, came from his clothes. Now he was naked and suddenly you were too.
The bed dipped, “hey, I’m right here,” his voice in your ear made you jump, “here, feel me,” he grabbed your hand and placed it on his chest. You felt his heartbeat and relaxed. He grabbed your other hand and placed it on his face.
“Kiss me,” you whispered, brushing your thumb over his lip, fumbling a bit to find it. He kissed your thumb and suddenly he was pressing his lips to yours. You wrapped your arm around his neck, deepening the kiss. You gasped when you felt his dick brush against your thigh. You could only feel where he was going next. He left open mouth kisses along your neck down to your collarbone.
Two fingers dipped into you again, pulling more slick from you. “Wait!” your cheeks heated up.
Levi stopped, “what’s wrong?” he caressed your face.
You turned away, “I—how big is your dick?” you covered your face.
There was a long pause and then a rare chuckle, “you want to know if it’ll fit?” You gave a timid nod. Levi grazed the head of his cock against your puffy folds. Slowly he sank in just the tip. It was jaw dropping girthy. “Guess,” he whispered. Inch by inch he stuffed you until you were at the base.
Your mind went into a haze, eyes lazer focused on the way you gaped around him. You bet if you were in front of a mirror you could see just how deep he penetrated you. “s—six?” you shook your head, it was more than that. The stretch was unfathomable. “No it’s—oh fuck—seven.”
You couldn’t guess properly, not with the way he snapped into you like he wanted you to feel him for days. Your breast jiggled by the sheer force of his thrust. They were sloppy, pent up, and dangerous.
“Shit, feel ‘s good,” he groaned. Your cream built up around the base of him. Squelch squelch squelch filled the room. You were a sight. Spread open, tongue out like a dog in heat, with seemingly nothing between your legs.
The pleasure possessed you with the way your eyes rolled and your back arched from your bed sheets. “L—Levi!” you reached your hand out; you found his cheek with surprising ease. He kissed your palm, slowing his pace just a bit.
“so perfect--you’re beautiful,” he slightly pulled out, breathless, shiny slick outlined his dick, “want to be yours,” he snapped his hips back into you.
You whined, scrambling to hold onto him again. He pounded into you faster, not caring about the plap of your skin clashing or the way your cream splashed on his lower abdomen. “yes—fuck yes!”
“Fuck—pussy feels like heaven,” He pushed your legs up higher.
“ngh! Uh—uhh—hmmm I’m gonna cum! Levi!” you cried.
His thumb rubbed furiously over your clit. Your cunt clenched wildly around him, sucking him deep in you wet spongy walls. Your eyes rolled back, and you clawed at his invisible back. You wouldn’t have the pleasure of seeing the marks you made on him.
He groaned with vicious thrust, “gonna make you mine, make you take this shit, fuck—take it—take it like a good girl,” he groaned. His hips jerked violently, spilling inside you with a rough moan. He stayed there a moment, and you watched your cum coat his cock, seeing some of your pussy twitching around him.
“I’m going to pull out,” Levi announced. You nodded, hissing as you lost the stretch of him. “Let me get you cleaned up.” He left and came back. You gasped when he picked you up.
“Oh a bath?” you shivered when your feet touched the cold tiles.
“Yes, we’re filthy, now get in the tub,” you felt a hand on the top of your head.
You both washed up, eventually finding your way back to the spare room with clean sheets. You laid on his chest, while he stroked your back. “Yes,” you whispered.
“Hmm?”
“Yes, I’ll be yours,” you chuckled.
“Good, I thought so,” he cleared his throat.
You rolled your eyes, “oh shut up, I bet you’re blushing right now,” you waited for his come back, “aha! I knew it, you’re just a softy!”
He pulled you up for a kiss, “shut up,” he mumbled against your lips.
