Monster-tale

Commission for @blueberrycoffee19

Request: Tentacle Monster x Fem Reader x Best Friend: They move into a new house together (the Reader and the Friend) and they’ve been told that there is a monster/creature that lives in the house but they don’t believe the story. So they’ve been living in the house for a couple months and they have noticed that their things sometimes disappear and then will just reappear. So one night they decide to have a sleep over in the Readers room and basically that’s when they find out about the Tentacle Monster (and they become a (throuple)couple). Note: If it’s okay the reader and her friend have had feelings for each other.

You looked between the building and your girlfriend, not convinced at all about the new house you two bought together. “Are you sure this is the place? What about the monster?” You knew it was, but sometimes you needed some reassurance. The place looked run down to the point of haunted house. You weren’t sure you wanted to be there more than two seconds, but it was technically yours… Fuck.

She was as calm as ever, just looking at the house with her big hopeful eyes, making you want to hug her until she melted against you. “Yes, dude, chill. They said it was a bit run down, but we can fix it. The monster is just an old tale, don’t worry.” She pecked your lips and smiled like a madwoman, looking like sunshine just appeared in a cloudy day.

You weren’t so sure about it, but you told her either way: “Okay, I will trust you on this...” You would trust her with everything if you were truthful about it. She was the best. But sometimes… Sometimes you felt like something was missing.

As expected, the house felt haunted. It started with bits and pieces, just some stuff disappearing. “Hey, did you see my pink top?” Your girlfriend asked during one random breakfast.

“Nope, it wasn’t there when I folded laundry,” you said between bites. Not thinking too hard about it, she probably misplaced it.

She looked deep in thought. “Let me know if you find it…” Her voice was unsure and something at the back of your head tingled, the same way as if someone was staring at you. You turned around, but there was nothing there, just shadows. Weird.

“Will do.” But something at the back of your brain itched, like you were missing something, like there was a bit more to it than just a missing top.

The top appeared in the bathroom hamper three days later, no idea how it got there or why. You checked there when she asked and it wasn’t there, definitely wasn’t there. Weird.

You two started to be a bit more careful with your stuff, but things kept disappearing and re-appearing in other places. No meaning, no reason, just missing stuff and it appearing in the most weird places. You didn’t know if it was your girlfriend messing with you, or if you two were just really messy… But something didn’t make sense.

Weird.

And on top of that, you had the sensation of being watched at all times. Like there was a presence behind you at any given moment, and it was creepy, but at the same time… It filled you with some kind of anticipation, like something big was about to happen. Sometimes you thought you saw shadows in the corner of your eyes, crossing the hallway, behind you or in the ceiling. Something like tentacles moving but they were never there when you turned around. And that continued for a couple months before you had enough and brought the topic to your girlfriend.

“We need to talk about this house,” you started, sitting down in front of her trying to look as serious as possible. “I don’t understand what’s happening but there’s definitely something else here, maybe someone else,” you finally confessed your paranoia to her.

“What do you mean?” She asked, setting down the hat she was crocheting.

You explained how you felt things moving, and couldn’t find some stuff… And you felt constantly watched. You thought you were going crazy, but the understanding in her face made you feel better instantly. You two talked it out, and turned out she was experiencing the same stuff as you. She even saw the shadow tentacles in the corner of her eyes! Maybe the monster tale wasn’t really a tale...

You two were confused at best, but most of all, you were annoyed by whatever creature was haunting you. So you decided to have a sleepover to see if you could lure the ghost, or whatever the entity they were, out. You barely hit the mattress when you heard something crash behind you.

“Did you hear that?” You asked, a mix of fear and anticipation filling your every cell. Your girlfriend was looking behind you, eyes big as plates and breath erratic.

And then you heard him for the first time. “Do not fear me, humans.”

You turned around as fast as Lightning McQueen. There was a monster there, a thin tall monster with purple skin and… tentacles? You were shaking, and to your embarrassment, the first thing out of your mouth was: “You have tentacles!” You cursed yourself internally at the stupidity of your words.

He chuckled lightly as your girlfriend facepalmed beside you. “I do… But I won’t hurt you… You are my precious mates, after all.” You looked at him not understanding what he was saying, your mind completely taken aback by that… monster. He was handsome in a way you couldn’t fully comprehend, ethereal in a non-human way. And you liked it, it was like something inside of you ignited in his presence.

“You’re what?” Your girlfriend questioned, her face mirroring the morbid curiosity in yours.

“Mates,” he repeated, as if the word was self-explanatory.

“As in Australians?” Your girlfriend asked, making you turn to look at her. What?

“No, as in my forever partners. Lovers,” he sounded like he was biting his tongue not to laugh. Which valid, what the fuck of a question was that? You were still looking at her when she looked at you, questioning.

You two had a silent conversation, thinking about what he said and how you felt about it. You thanked the goddess for having such a connection with her. “I… We need more info on that, big dude,” you finally let out.

You two sat down on the bed as he curled his tentacles under him, making some kind of chair. He explained how he had been waiting for you since before you bought the house, and how since then, he had been trying to make contact with you two but didn’t know how. He took over the basement and had been staying there and helping around the house as much as he could, but sometimes… Sometimes he stole your stuff because your smell calmed him in the cold nights. You two swooned at him when he said that. He was so cute and so adorable… In a monstrous way.

After that, everything started to make more sense. He didn’t hide anymore, he was constantly around, helping in the house and being a perfect gentleman (gentle-monster?) to you two. At first it was really weird, but bit by bit he inserted himself in your lives, and you started to gain more and more affection to him… It helped that he was extra affectionate. A touch here and there, a little slap on the ass to tell you how good you looked in that skirt. He was always doing nice stuff for you two, and it was driving both of you insane.

Insanely hot and bothered.

He didn’t try to go further, going back to the basement every night and leaving you two alone to do whatever you wanted. But out of respect for him, and knowing he could hear everything happening at the house, you didn’t masturbate. Or had sex. Or anything… Both of you were a bit on edge. Pent up frustration and excitement filling your bodies and making it so you two would grind against the corned of a table if he didn’t act on it soon enough.

But he didn’t say anything about sexual stuff… And you had enough teasing.

“Do you want to fuck us?” You blurted one random day.

Your girlfriend cursed as he choked on the water he was drinking, coughing hard. “Wha- what?” He let out when the coughing stopped. You apologized softly, and hid your blushed face in your hands.

“You’ve been teasing us non-stop, and it’s driving us a bit insane. We are ready.” Your girlfriend told him, smiling at him in that tender way that made your panties melt. If his hooded eyes were any indication, that smile had a similar reaction on him.

“So fucking ready,” you added, sending him your best bedroom eyes (which probably looked ridiculous at that point). “If- If you want, that’s it,” you added, feeling self-conscious all of sudden.

“Are you sure?” He asked, looking equally hopeful and excited.

“Yes, please,” you both said at the same time. He chuckled at your synchronicity and you felt the tip of one of his tentacles ascending your leg. You saw another doing the same to your girlfriend. Anticipation filled you and you got wetter and wetter.

“Bedroom, now,” he ordered. Both of you ran to the bedroom. You saw your girlfriend throwing her clothes anywhere as she ran. Your mouth watered seeing her naked in front of you, her ass jiggling. You licked your lips and let out a yelp when you felt a tentacle spanking your ass lightly, you giggled and ran faster.

By the time he arrived to the bedroom, you two were already kissing over the mattress, groaning into each other’s mouth. He approached you two, and you broke apart, looking at him in his naked glory. His tentacles were moving all around him and he looked every bit of a monster he was. And that turned you on more than anything ever before.

You heard your girlfriend moaning next to you, and when you looked to your side you saw multiple tentacles curling around her body, suckers over her nipples. You groaned at the image, arousal growing increasingly. The chorus of screams and moans was like a filthy symphony of your love. Not two seconds later, more tentacles joined the party and curled around your legs, ascending until they were sucking hickeys over all your sensitive areas. The moment they made contact with your nipples, you cried out.

You felt his tentacles parting your legs, exploring your inner thighs as he teased your pussy. “I’m going to fuck you so well, you won’t be able to walk tomorrow,” he promised. His tentacles were probing your entrance, asking for permission. You groaned something like a yes, and he started pushing inside, but before you could react, he was manhandling your girlfriend so her pussy was right over your face. “Make her come before I make you come. Let’s see who is better.” Your competitive side rose to the occasion, grabbing your girlfriend’s hips and pushing her down to eat her out.

Your girlfriend riding your face as if you were a mechanic bull. The constant grind of his tentacles against your pussy and clit, accompanied by the feel of your girlfriend grinding down on your face was driving you insane. You were the sandwich of the most delicious creatures. He started to fuck you slowly, but soon he was fucking you like a machine, his tentacles all over you at the same time. You were in heaven.

You tried to make her cum faster, your lips over her clit as you finger fucked her tight pussy, but he was so good, so precise in every single one of his tentacle’s movements… Your orgasm took you by surprise, screaming around your girlfriend's flesh as you arched your back and came apart. Your ears were ringing and your surroundings were blurry as you felt him move you around. Before you realized, you were laying flat on your girlfriend and he was fucking both of you at the same time, holes aligned and filled to the brim.

He fucked you two non-stop, so many tentacles and sensations you didn’t know how many places he was touching at the same time. Your girlfriend was kissing you passionately as she groaned around your open mouth when he hit her G-spot perfectly. You cried out when he did the same to you. You came, and so did she. But he didn’t stop. He kept going, grunting and telling you how good your pussy was, how pretty you two looked together. It was intoxicating in the best way possible.

By the time he came, your body felt like a rag-doll and your girlfriend was a mess. Both of you were fucked out completely. He groaned as he filled you two with warm cum. You groaned as another orgasm rode your body, almost painful. You blacked out for a couple seconds and came back to him softly cleaning both of you abused pussies. Your girlfriend was fast asleep, and he was looking down at her with the most tender eyes.

“Stay,” you asked him softly as you saw him try to reach for the door. He turned around, his eyes hopeful. He nodded curtly and approached you. He laid behind you and held you against his chest, his tentacles surrounding both of you in the most comfy embrace.

Your eyes were closing when you heard him whisper: “Thank you for accepting me.”

You fell asleep with a smile on your lips and thinking how glad you were that the old monster tale wasn’t really a tale.
