[tentacle] The monster under the bed

Summary: Your aunt's house is not as empty as you thought.

A/N: For kinktober 2023, I have a new town full of monsters. Here is the masterlist.

The change in the air is thick and heavy after you leave the Welcome to Grimbrook sign behind you. You feel it in your core. It's cold and silent. For a second, everything goes quiet, and the time seems to stop. The rumbling of your car gets muffled, and the colors of the lush, green forest at your sides fade into a milky fog flowing above the ground. You can't see the tall mountains and their sharp edges in the distance anymore. The clear blue sky turns gray, and you can't find the sun anymore, either. Just a few dim rays shine down on the road in front of you, showing your way to the village next to the sea.

As you get closer, you can smell the salty scent of the water even through the closed windows of your car. It's heavy in your nostrils. The sound of the waves gets louder too. From the top of the uphill, you can see the village with its old stone buildings and the sea behind everything. It seems colorless, merging into the dark sky at the horizon. It is beautiful and terrifying at the same time. There is something in Grimbrook that you can't pinpoint but freezes your insides. The only light you can see comes from a lighthouse at the edge of a cliff. It emits a soft, rhythmic beam of yellow light that cuts through the heavy fog, casting eerie shadows over the still village. Seagulls glide through the mist above the white seafoam, waving across the dark surface.

"Okay," you hum, forcing your eyes to go back to the GPS on your phone. The blue line clearly shows your way to the house you have to reach before night falls. It leads you out of the center of the villages until you reach a small suburb with Victorian houses standing in a long row with grand iron gates and gardens.

The monotone voice of the GPS informs you when you reach the right house, and after sitting in your car for a few more minutes, you have no other option but to get out and make your way up to the porch. The wooden planks creak under your steps as you look around a bit better. The house is old, with tall walls, characterful windows, and a dark green door with a golden knocker in the middle. It's cold in your hold as you knock it against the door.

You don't get an answer, though.

The door opens, and you find yourself facing a narrow foyer with stairs on the right side. Pictures and paintings hang on the walls in dark wood and golden frames. You can see the entrance of the kitchen at the end. And on your left side, there is an arch that leads you to the living room.

"Hello?" You break the silence. Your voice is hoarse and quiet. You have to force your legs to move and not turn back to your car and leave this place immediately. "Somebody?" Your gaze lands on a small table in the corner next to the entrance door. There is a letter with your name on it.

Dear Cat, I'm sorry I can't be here when you arrive. Make yourself at home, and we will talk tomorrow. Delilah

"Great," you sigh, letting the paper fall back onto the surface of the small table.

For a second, you think about searching for a hotel or something similar to spend the night, but to be honest, it doesn't sound much better either. You know you should leave the town to feel better, but it's not an option. So you close the door behind you and wander further into the house.

You got a call a few weeks ago about your aunt you met long years ago. She died, and now you have a house. You can keep it. You can sell it. Whatever you want.

The house is old, with a lot of wood, dark colors, and golden details. There are still newspapers from months ago on the coffee table in the living room. The rug under you is faded and thin. The floor creaks every now and again. There are two rooms and a bathroom upstairs. The bigger room is still occupied with your aunt's belongings. The scent of her perfume still lingers in the air. You remember her when you were a kid. She came to your grandmother's funeral, and you never saw her again. Nobody really talked about her in the family. The only things you know are that she was kind but preferred her own company above everything else. She lost her husband in her late twenties but stayed in Grimbrook, barely leaving the town.

The guestroom is much more bare than the other parts of the house. A bed in the middle with two nightstands and a lamp. There is a drawer in front of it and a mirror on the wall. The window is slightly open, letting in the cold autumn breeze. You have a view of the street from here. It's calm and empty. The only reasons you know you are not the only person in the town are because you can see a few cars here and there and a dog barking in the distance. The fog is thick and heavy. You can't see the end of the street through it.

After wandering around the house some more, you decide to call your friend until you have no other option but to change and try to get some sleep.

Climbing up on the bed in the guest room, you settle under the thick covers. The scent of the linen is faded and mixed with dust and the night air coming through the window. It's dark outside, not counting a few lamps on the street. Their orange lights filter into the room. And everything is quiet. So quiet that your ears almost start to ring. You are not used to it. You live in the city with constant noises.

When sleep takes you, it's restless and everything but relaxing. You fidget and turn, trying to find a comfortable position as you balance between the darkness and the real world. Your head feels just as foggy as Grimbrook, and at some point, you can't decide if you are dreaming or not.

You are on your back, one arm on your stomach, and the other is next to your body. The autumn breeze caresses your skin, moving up from your feet to your ankles and calves. Shiver runs through your spine at the feeling. You want to reach out for the blanket, but even though your arms move, they do not obey your command. Something pets the thin skin of your wrist. It's soft and barely noticeable. You feel your muscles stretch as you reach up to the headrest of the bed, but you don't even know why. The cold moves up further on your legs. It curls around your flesh, spreading you in the middle of the bed. Your heels dig into the mattress. Your body tenses when your limbs don't do as you want. A frown deepens between your brows.

"What?" A hoarse grunt leaves your lips. When you open your eyes, you meet darkness, and you are not sure if you are really awake or not. Your eyelids are heavy, and not even a second later, you fall back asleep again.

The bottom of your pajama slips down on your legs. The waist stretches around your parted legs. Something slides up on your stomach under your t-shirt. It is slick and soft. A gasp echoes in your room when it flicks your nipple. The thing curls around the flesh of your tits, groping and caressing. Your nipples harden under the strange touch. Saliva? A tongue?

Where are you?

And there is something else between your legs. The muscles of your thighs tense, and the hold around you tightens.

"What?" You groan again into the silence. As you look down on your body, you see your t-shirt around your neck. Your breasts are bare. Something dark and purple curls around them, squeezing and licking. The teasing on your nipples is almost painful. At the back of your mind, you want more. Your head falls back onto the pillows, and you are asleep again.

The tentacles between your legs move up and down on your pussy. Your panties are ruined between your wet center and the slick touch of theirs. One of them flicks your clit. Your back arches at the feeling. The cold night air hits your aching pussy when the thin fabric is pulled aside. One of them stays around your clit, flicking and rubbing the hard bud. The other one goes straight to your hole.

You want to move. To get closer or farther away, you can't decide. The tendrils don't let you go anyway.

You break the silence with a sudden moan. The limb enters you slowly. It slips into you easily, stretching your walls until you can't take another inch. It fills you up.

"Fuck," you groan.

Your breasts are soaked. The slickness on your skin shines under the dim streetlights. The tentacles play with your flesh, rubbing and pinching your nipples. The pain takes your breath away every now and again until you feel dizzy.

The others between your legs move without pausing even for a second. Your clit throbs, and your walls flutter. Pleasure flares inside your veins, rushing through your body with such force you never felt before. Your lungs burn for air, and your muscles ache as you lay taut, panting.

When you open your eyes, you see the ceiling and the old lamp hanging above you. You want to force your mind to think, to panic, to do something, but your senses are full of pleasure. The only thing you can do is moan and grind against the tentacle inside your pussy. It pounds into you, reaching every spongy spot inside that makes you see stars and beg for more. The sheet under you is soaked with your mixed juices. You can feel it dripping out of your hole.

Fuck, you want to shout, but you can't find your voice. You just shake and tremble in the hold of the limbs keeping you in place on the bed. Every nerve in your body is on edge, and when it snaps in your lower stomach, you can't remember how to breathe. Your climax forces you down and stops you from moving. A thin layer of sweat shines on your bare skin. Heat burns you from the inside, and your pussy flutters and sucks on the tendril inside you. It still moves in and out. It twitches and rubs against your walls. And doesn't stop even when the darkness envelopes you again.

When you wake up the next morning, you need a few minutes to remember where you are. The sun shines through the window, casting an orange hue over the old rug in the middle of the room. As you sit up, your t-shirt falls back over your torso, but your pants are still around your knees.

"What?" You grunt out. The question is barely louder than a whisper. Your hand shakes as you reach down between your legs. Your pussy is wet, sensitive, and swollen. A moan escapes you when your fingertip slides over your slit.

Your dream is still vivid in your mind. You can feel the tentacle in your pussy, using your hole and rubbing your clit. Your center starts to throb with need at the memory. And your breasts. Your other hand grabs one of your tits. Your nipples are still hard peaks through the thin fabric of your shirt.

"Hello? Cat?" The sudden noise snaps your head up to the door of your room. The voice comes from the entrance of the house. "It's Delilah." "Hey!" You croak out. You are not even sure if she can hear you. "I will be down in a minute." "Great!" She shouts back. "I will make some coffee, and we can talk about your plans with the house." Your fingers sink into your hole. You are still stretched out. You move in and out of your pussy easily.

Yeah, you think, you need a few nights if you want to decide about your plans.
