You stayed still, sitting on the soft fabric that covered your bed, watching your boyfriend arranging candles on the empty and clean floor, all as he ranted about his family, just like he does every single time that he visits you.
How overbearing and his parents were, how suffocating his job, or how nagging his younger sister was. The same old songs, over and over.
Still, you cared about him, you two were together for years by now.
You still remember the moment he entered your life, you were alone, vulnerable and hollow. He came into the scene and filled your gaps, he was there, where you were at the lowest point of your life.
Yet, it seems that you can't do the same for him, no matter how much you try to help him in any form, he just shuns you away. The closer you get, the farther you end up. The only thing you could do was listen.
You would nod to any question that he asked you, since he in reality didn't look for an actual answer, he wanted you to agree with him.
The sound of fingers snapping broke you out of your thoughts, directing your attention to your boyfriend, who wasn't pleased with you ignoring him. He was crouching on the floor, candles in different points and salt that copied a pattern from a book next to him.
"Sorry, were you saying?"
"C'mon here".
You crouched next to him, he looked at you with those eyes that you adored and gave you a nostalgic smile, a smile that you thought had been left behind years ago, you returned the gesture.
He grabbed one of your hands with his. The warm feeling of his hands over yours, you missed and wanted to hold onto it for a little longer.
But reality hit you as you felt a cold and sharp metal slashing the palm of your hand, you hissed at the pain and freed you hand from his grip immediately, walking backwards, away from him, you covered your wounded hand with the other and watched how your aggressor dropped the blood drops from the knife into the floor drabbles.
"ARE YOU OUT OF YOUR MIND?! WHAT WAS THAT FOR?!".
You yelled at him, wanting an explanation, why did he do that? But your demands fell on deft ears, as he mumbled to himself, you could barely understand the words that he was saying, you caught up some phrases like, how he was going to be free, leaving everything behind and how the rest would be dragged to hell.
His eyes were beaming with madness, excited to meet the one that would make his dreams come true...
But nothing happened.
The seconds that passed, soon turned into minutes, and everything remained the same, except for the impatience that your boyfriend was feeling, it evolved into annoyance and later to anger.
You wanted to say something, but you knew well that he would just yell and curse at you, you had enough with your bleeding hand, you didn't need more trouble.
Your angered boyfriend grabbed his jacket and stormed out of your apartment, leaving you behind with a wound in your hand and a mess on your floor.
You first treated your hand in your bathroom, cleaned it and covered it up, and when you came back to the bedroom you groaned at the candle wax dripping in your floor and at the blood that stained it. You were thinking about ways to clean it and your felt chills roaming your body.
The room felt more cold than before, and a strong gust opened your window, you covered your face at the unexpected attack from the wind and closed your window, making sure that it wouldn't open once more.
The lights started to flicker and the room started to shake, making you lose balance and falling on your side on the floor. A dark cloud of smoke formed around the floor drawing that your boyfriend did, and from it a figure came out of it.
Soft and silky short hair, accompanied by a small golden head piece and dark horns. Black bodysuit that hung around his slender figure. A thin and long dark tail and a pair of dark bat wings that grew on his back.
He was beautiful, that you could have mistook him for an angel at first glance.
His sharp red eyes landed on you, his face had unpleased written all over it, clearly not feeling happy about being here.
"To be dragged out to the mortal world in a moment like this... I swear-".
You interrupted him by your scared yelp. "A, a demon!? Are you, are you going to take me?". You stuttered in response to your nervousness, and crawled backwards, creating distance between your two.
"Do I look like Hel to you?". The red-haired being answered your stupid comment with sarcasm. He sighed and cleared his throat afterwards. "I am Elm, an Incubi from the realm of the demons and lady Embla's right hand".
"I... I'm [name]". You introduced yourself to the devilish man.
"Tell me [name], what does a person like you want from someone like me?".
You were confused at his question. "Me? I... I'm not looking for anything".
Your reply fell on Elm like a boulder in the middle of a flight, surely you're jesting right? Be mindful, he's not fond of jokes. "You're kidding right? Then why waste both of our time by summoning me!?" His wings and tail were stiff, he resemblanced to a bat that was ready to launch at you.
"I didn't do it!". You covered your head with your arms and closed your eyes.
"Isn't this your blood!? Who else if not you!?". Annoyance was growing inside of his body.
"My... Boyfriend". You admitted. "I...heard him, he said that he will leave everyone and be free...". You stopped from running your mouth, you knew what he meant by that.
"Your boyf- agh!". He snapped. "For the love of- I need to request my lady to remove any ancient Emblain books from the mortal world". You didn't understand what was happening and he couldn't tell, based on the expression on your face. "You don't get it, don't you?". You denied with your head, he took a deep breath to attempt to calm himself. "First of all, he summoned the wrong type of demon, I'm an Incubi". With each word the anger increased. "Second of all, if your boyfriend wanted a demon to be bound to him, he needs to use his own blood, it's a sacrifice after all. If you use something with no value to you, or use someone else's, then it's not a sacrifice. What a fucking joke of a man". He sighed.
"Can't you go back to hell? or whatever your place is...?".
"Not hell". Why was that such a common misconception? Elm wondered. "I can only go back if we both fulfill our contract".
"And... What do I have to do?". You asked him.
The Incubi grinned, his fangs shimmering in the dark room, and in the blink of an eye, you went from the corner of your room, to laying on your bed, the bat-resembling demon pinned you down, your hands were trapped under his hands, his right knee separated your legs.
"Huh!?".
"Don't move too much, you may enjoy it if you stay still". The sensation of his hot breath in your neck, made your skin quiver, his fangs caressed your skin, and you closed your eyes.
Will you give in? Or...?
"No!". You opened your eyes and squirmed underneath Elm, freeing yourself and getting him off you. You sat in your bed. "I can't do it, I can't do this to... him". You couldn't dare to cheat. Love was built with trust, if you did that, you would be as bad as anyone who hurt you or him in the past.
It was not right.
Elm groaned at your stupidity, he just cut your hand and you still decided to remain faithful? Mortals were truly a bunch of morons, no wonder they have those cows called angels to guide them, they were useless with zero common sense.
Still, there was no point in trying to argue with you, if you weren't willing to do your part, he won't be free.
"I can't believe I'm stuck here because of that bum that you call your boyfriend". His wings raised him from the bed, keeping in the air. "At least you're pretty to look at, can't wait to see your expression at every misfortune that comes in your life". The tone of his voice was like he was craving for bad things to happen to you, almost mouthwatering.
And that was the beginning of your new life, with an Incubi living under the same roof as you.
At first, he detested having to stay with you, for he just wanted to go back to his home realm with his lady Embla. You didn't tell your boyfriend about the ritual actually succeeding nor about Elm, luckily, Elm was able to make himself invisible to anyone other than you, his contractor, though it was hard to not acknowledge him, anytime that he mocked your partner.
The Incubi liked teasing you, and eventually started to enjoy your company, you weren't the worst mortal he could have been bound to. But those feelings of enjoyment soon bloomed into something deeper.
He was falling for you.
For Embla's sake, now he loathed your boyfriend with a burning hatred.
If only he could have you in his arms, holding you, or maybe having you sit on his lap, as his tail rolls up to your tight. However, that boy toy of yours keeps getting in the way!
Oh, Elm wanted to kill him so badly.
How should he get rid of him?
Maybe torture him first?
So many options to pick...
But it wasn't enough, he wanted him to suffer, to be chained to endless misery. And he had the perfect idea...
You haven't seen your boyfriend for a while now, no call or messages have reached you, you talked and asked about him to his friends and family, but to no avail. You looked at his socials, but there wasn't any luck, you attempted to fill a report for a missing person and haven't heard from the station in a while.
You were heartbroken, did he really do it? Did he leave everyone behind? Including you? Was this the end of the rose colored dream? Has everything really ended?
Not only that, but Elm kept pestering you, mocking the disappearance and presumably death of your boyfriend, yet he also tried to get you to seek comfort in him.
And he got it. You wanted to be held with love and care for a while. Was that a bad thing?
You were desperate for affection that you gave in, you leaned closer to him and pressed your lips against his, he grabbed your hips and pulled you closer, the two of you melted in each other's bodies.
Your partner woke up groggy, he was confused by his surroundings, everything was dark, except for a giant red moon that illuminated the sky, when his mind went back in place, he tried to move, only to find out that his entire body was chained. Wherever he was, it was an inhuman place.The only thing he could do, was to stare at a dark cloud that projected images of familiar faces and places.
Specifically, he watched you in your room, melting on top of a strange looking man with bat wings that wrapped you both.
You begged for his touch, pleading for his attention and calling the red-haired man's name like a mantra, all while your boyfriend watched in horror.
The creature of the night marked your neck with his fangs, his devilish smirk didn't go unnoticed by your partner, and those red devil eyes stared back at him, as if he knew he was watching you both.
Your boyfriend was trapped in an unknown place for god knows how long, and the only thing he could do, was watch how this demon steals you from him.
