The dingy bathroom with its dim lights that kept swaying overhead were adding onto your paranoia. The smell was awful and your stall had graffiti all over it in various colorful tones and language while the lock was held together with hopes and dreams. But you were desperate. It’s not like you wanted to use a subway bathroom at night, but you had no choice. You just needed to hurry up and get out of here.
That’s when you hear something that causes your nose to crinkle in disgust.
“Hic, I could’ve totally drank more!”
Men?!
Your breath hitches as you hear two men walk into the bathroom in a drunken stupor.
“Where are da urinals?!”
“Must be the ladies’ bathroom.”
They start laughing and you start to feel your skin crawl as they continue to walk further in.
“You think there’s some…”
“What?”
“Ladies in here!”
God, I need to get out of here!
Their footsteps are getting closer. You instinctively stand onto the toilet seat and squat.
Stay hidden.
“Hey ladies!”
They snicker sickeningly before one of them stumbles into your stall door.
“A-”
You cut yourself off by slapping your hands onto your mouth.
“Did you hear that?”
You see their eyes peering in through the cracks in the sides of your stall door where the hinges connect. Their laughter becomes raucous as they try to coax you out.
“Pretty lady~ Come on out~”
Escape. Escape. How can I escape?!
Your eyes dart around but there’s nowhere to go. You can jump into the next stall, but you’d still be a sitting duck. Fighting was not an option, who knew what they possessed.
Your heart rate explodes when you feel the stall rattling. One of them is trying to kick the stall door open, while the other is still trying to get you to come out willingly. Their voices eventually become enraged and you try to keep the door closed with your legs pressed against it, refusing to put your whole body against the door, in fear they could drag you out by the ankles.
“Just get out of there, stupid bitch!”
They’re shouting and banging against the door as you try not to squeeze your eyes shut from the entire situation.
Go away! Go away!
You feel your eyes shut of their own accord and let out a scream from sheer panic, hoping that someone, someone that wasn’t a monster, could come and save you.
…
Seconds pass.
Minutes go by.
Silence.
You slowly open your eyes as you realize how quiet it’s become. There’s no trace of the men. The broken lock precariously hangs off the stall door before the hinges creak and the door slowly swings open. Your heart rate is still dangerously high and you’re too scared to move. Your stare slowly moves down to the floor and that’s when you see it. Dark trails of black liquid coat the floor where the men had been standing. You shakily stand and walk closer to the mess. It looks like whatever was responsible for this had dragged the men out of the bathroom and into the hallway.
This has to be fake. Yeah! A T.V. skit or a sick prank!
You can feel your knees buckling and attempting to make you fall over. Your hand clutches the stall pole like a lifeline.
I can’t. I just… need to get out of here!Each step feels like you’re one more minute closer to death.
I have to be brave… Screw it!
You reach the doorway of the bathroom and book it. You run to the left, another left, a right, and another left.
This is the way back to the train platform!But when you stop and look around. You’re panting, out of breath, and back in front of the bathroom. The black ooze seems to have spread to the walls and the rest of the floor.
No way.
You’re sure you went the right way. But…
You gasp in horror and step back when you see something coming out of the biggest spot of ooze on the floor.
Nope! Nope!
“W..a..it..”
You hear a gurgling noise.
Absolutely not!
You run again and decide to bolt in the opposite way from where you just came. A dark foreboding open area that leads you further into the subway tunnels where mainly only staff dare to approach, if at all.You crawl under holes in iron gates and kick open doors to jump down flights of stairs with no clue of where you’re going and if you’ll even remember the way back.
You finally stop to wheeze. Running until you were out of breath.
This is just a nightmare. You just need to survive long enough to wake up, right?!
You look around in distress and confusion. It was an abandoned underground rail station.
Are trains even supposed to come this far underground?
Apparently not, there were train tracks but they led to dead ends in both directions. Brick walls covered in mold and dirt surrounded you on all sides. You could only continue forward through the tunnel or back the way you came to that monster.
Drip.
You feel something land on your nose. Wet and heavy. You wipe it off. Black, sticky liquid clings to your fingertips. You slowly tilt your head up and see black puddles forming on the ceiling as the liquid drips onto you.
“Kyah!”
You accidentally fall onto your ass in abject terror and try to get up and run away, only to feel a harsh tug at your ankle. Whatever that liquid was had amassed into a tentacle and gripped onto your ankle, stopping you from sprinting away.
“W..a..it..”
You scream your head off until,
“MMFFF!”
A black tentacle is shoved into your mouth.
“Shhhh…”
You’re helpless but to watch a towering figure emerge out of the ooze. Globs of dark ink fall off its body before it jiggles into a solid being of mixed colors and human shape.
What the fuck is that?!
The creature smiles at you.
“Don’t be afraid. I don’t bite little ones.”
Its feet click against the floor as it approaches you. More tentacles rush out and bind your wrists together and your knees.
“Just to make sure. You’re a determined one.”
It sighs as you begin to struggle again. Your body writhing against its tentacles.
“I hope you do realize how futile that is.”
And that’s when its piercing green eyes meet yours. It’s analyzing you as it hums while you do the same but with muffled sounds. Jet-black hair, glowing green marks, black and purple clothing with ooze all over, some clumps are even floating in globs around him.
This is clearly some magical monster! I’m dead!
“What are you doing?”
It asks in a bored, baritone voice as it notices a few tears streaming down your face.
“I already said I do not eat little ones like you. Now, do not struggle.”
You feel its appendages slowly letting go of your limbs and placing you back onto your feet.
You sniffle as you rub at your eyes with your balled up hands. The adrenaline and stress finally become too much for you.
“Why do you still cry?”
It looks at you with its head tilted in apathetic confusion.
“I’m lost…”
Not a lie, but not exactly what you were crying over.
“Lost?”
The creature’s tail swishes behind it.
Oh God, it even had a tail.
“Where did you come from?”
You stumble over how you could describe it.
“Uhh…”
You end up pointing upwards.
It looks up at the ceiling.
“The lavatory where you were being attacked?”
“No, not-”
So IT was there when those two men had been attacking you!
“Above that. A world with blue skies and bright lights.”
It continues to stare at you as its tail swishes in thought. Well, you hope it’s thinking or… You’re still unnerved either way.
“D-do you have a name?”
It finally blinks.
“Malleus.”
You gulp nervously. You don’t want to give it your name but…
“Y/N.”
It’s only common courtesy. Yet that smile it gives you, like a conniving Cheshire cat, makes you think otherwise.
Did I mess up?
“It’s a pleasure to meet you, Y/N. May you enjoy your stay in this dimension.”
Dimension?!
It doesn’t expand on what it said nor does it bother to comment on your startled expression. It just turns its back to you and begins to walk away, leaving you no choice but to follow it.
“H-hey, wait!”
You speed up a bit to catch up with it.
“What do you mean by dimension?”
“A world of decay. Yours sounds far too bright and colorful.”
It says that with such disgust that you feel like defending your home but… It’s best not to upset whatever this person is since it seemed they were trying to help you.
You stay silent as you follow it down twisting corridors through numerous decayed and abandoned versions of places you have and haven’t been to. Pools, playgrounds, schools; this place feels endless and you’re starting to get overwhelmed again. If it weren’t for Malleus’ humming. If you got distracted and accidentally lost sight of Malleus, you could still follow its song and locate it. It was almost comforting.
“Hey Malleus,”
“Hmmm.”
“What are you humming?”
“Interested, are you?”
You nod as you continue to walk beside it through a vine ridden labyrinth. The ceilings are closed off and the only visible light is an off-putting green emanating off of Malleus’ very being.
It chuckles before answering you.
“It’s a song from long ago.”
“Long ago?”
“Yes, very far in the past and very far from its place of origin.”
So Malleus isn’t from here either.
“Malleus, where do you come from?”
“A dark forest with upturned roots and burnt thorns.”
It stops walking and turns slowly to stare at you.
“Because of the children of men.”
You look at it with confusion.
Once again, it doesn’t say anything else after it finishes staring at you and faces forward to continue leading the way.
Days must have passed by now, if not weeks. There’s no way they couldn’t have. Malleus has been your steadfast guide, but it feels like you’ve been walking in circles for ages and even more mysterious is that not once have you felt tired or sore.
Maybe it’s because I haven’t been running for my life like before?
You’ve gotten closer to Malleus, asking him questions when the silence was too much for you and the environment too fear-inducing. He was always up for a conversation, speaking for hours about any topic that you would introduce. It’s like he was waiting for you to initiate a conversation, bursting at the seams to divulge his knowledge and opinions with you. You two hadn’t seen anyone or anything else this entire time.
Was his presence perhaps keeping the other creatures away? Were there even any other creatures? Whatever. You just need to get back your reality.
“Malleus?”
“Yes, child of man?”
“How much further?”
“Depends.”
“On what?”
There were rare times where he would fall silent and unfortunately this was one of those times. He would grow quiet when he didn’t want to answer your questions and you wouldn’t push for one because you didn’t want to lose your only companion in this strange dimension.
“We’re close.”
You perk up as you hear him utter those words.
“Close to my home?”
“Something like that.”
“...”
It was definitely better than nothing.
He begins to speed up.
“Malleus?”
You quickly try to catch up to him. The thought to grab his tail occurs to you but you refrain. You see him turn a corner and run faster, only to end up sprinting into his back and grunting as his tail wraps around your waist to stop you from falling.
“Are you alright?”
“Yeah, I’m fine.”
“Seems like we missed its arrival.”
His tail slowly unravels from your waist as it returns you to an upright position. You manage to turn your head in time to glimpse at what he’s looking at and see a door fading into a wall right in front of your eyes.
“That…”
“That was your way to your world. What a pity. Back to traversing the terrain it is then.”
No! No! No!
“Malleus, no way! There has to be something else we can do!”
“Hmmm?”
“I’m exhausted.”
“One cannot feel the full limitations of their mortal form here.”
“No, I meant mentally!”
“I see…”
He stares at you as you wait for a response. You feel like you’re losing your mind.
“What do I need to do to get out of here…”
You slump down a nearby wall and onto your knees.
You hear a deep chuckle.
“Very well then, my dearest.”
You look up at him from your spot on the floor.
“There is another way if you’re willing.”
“I can trace the door to your dimension in a much more efficient manner if you were to give me a piece of you.”
You seize up before surrendering.
Whatever it takes to get out of here.
“Like my finger? Do I need to chop it off? I can’t do that… You can! Do it for me!”
You extend your hand to him. Your pointer finger almost touches his robes as you reach for him.
Malleus’ eyes blow wide in shock.
“Goodness, you would go to such lengths?”
You nod.
He shakes his head and gently takes your hand before kneeling in front of you.
“Nothing like that. I shall not harm a hair on your head, little beastie.”
“Are you sure this is the best method?”
“Do you doubt me?”
He gives you a mischievous smile as he fondles one of your breasts.
Yes, you’re doubting him! Having sex to find a door sounds absurd!
You’ve long been stripped of your clothes, with Malleus not wasting a second to savor you. You were hoping he would just fuck you and move along but no, he was intent on making love to you.
“Akin to fine art...”
And he was mumbling sweet praises to you while kissing your skin! You were really scared you could end up getting attached to him at this rate! You already were.
You let out a soft sigh as he holds your pliable body gently in his hands. His arms are wrapped around your waist firmly to keep you standing up as he continues to pepper kisses onto your skin.
“My dearest sweet.”
He nibbles slightly on your earlobe as his hands slowly begin to venture further down. You jolt and he presses his head into the crook of your neck.
“Are you enjoying yourself~”
You end up grumbling in frustration because of how flustered you are.
“Let's just get this over with.”
Out of the corner of your eye, you notice his smile quickly fade into a frown.
“Y/N, part your lips.”
Your body moves of its own accord, shocking you as your jaw slacks open. His tongue dives into your mouth as he tries to devour you whole.
“Mmm~”
He's swallowing your moans and his grip on you is forcing your back into an arch. Dipping you further and further until you're eventually backed into a wall and he's pressing you for everything you've got. His hand tangles into your hair like he’s not already shoving his tongue as far as he can down your throat.
“Mmmm!”
You let out a high-pitched whine and tap his arm as a cue to Malleus that you’re losing air.
His eyes seem to flash and slightly widen before he slowly releases your lips. He’s moving at a millimeter a second, relishing in your warmth and softness, not wanting to let go at all. Strings of spit connect your lips as hot breath mingles in the small space that had been created between you two. His nose constantly brushes against yours.
Why is he so desperate…
You clear your throat before deciding to ask,
“Malleus, do you have enough pieces of me?”
He shakes his head as he gives you an upset and pleading expression.
“No. Not enough.”
He’s diving back in with gluttony. His lips on yours again as his arms wrap around your shoulders to bring you closer into him. His tail latching onto your waist in an effort to force you to stay in his embrace.
He ends up growling a single word when you pull away to breath again.
“Stay.”
“Malleus?”
You ask nervously as you feel his strange tentacles shoot out from beneath the ground and curl around your limbs. Your wrists are bound above your head and your legs are pulled open. Two stray tentacles decide to swarm up to your chest and grope your breasts. They pinch and pull at your nipples while squeezing the soft flesh underneath before exploring the rest of your form.
”M-!”
His lips are back on yours.
What’s with this guy?!
You choke on his tongue when you feel his claws trail to your lower lips. His fingers split open your folds and his thumb begins to rub circles onto your sensitive bud.
“Please… please…”
Small pleas leave his lips when you scratch against the dark appendages to let you breath. You’re not sure if he even realizes he's mumbling to himself.
“Need you… Want you…”
His mouth ends up abandoning your lips in favor of your neck.
“Wish to hear you…”
He sucks bruise-making hickeys onto your soft skin as his fingers finally plunge into your heat.
“You’re so warm.”
His fingers are ice-cold inside of you and make you squirm. Your legs shake from the pressure of his long digits stretching and sliding in and out of you with minimal constraint. Your voice quivers as you say his name and you notice a hint of a smirk on his face, if he wasn’t so far gone already. Darkened cheeks, your spit covering his lips, and his forked tongue tracing circles onto your chest before flicking your nipples.
“Mmm!”
The ooze covering his body shifts and you feel him move to tower over you fully. He hooks one of your legs over his arm by forcing the tentacles to position your body higher as they wholly support your weight. You whine as he begins to kiss you again. Your lips are swollen and bitten red by now. He chuckles as he pulls away,
“Shall we move onto becoming one?”
You feel something stiff and veiny hit your clit and keen into Malleus. He drags it across your puffy folds before rubbing it against your entrance.
Is this his cock?! He is big so it makes sense! But-!
Your brain goes blank as it slowly inches into you and knocks the air out of you. Veins, bumps, ridges, you can’t identify what’s going on with his cock besides the sheer girth of it.
“M-Malleus!”
His hand is quickly intertwining with one of yours.
“I’m here.”
Tears start to dot your lash line and he laps them up with care as they fall down your cheeks.
“Am I harming you?”
You shake your head.
“So we may continue?”
You shake your head again making him sigh.
“I- It’s just too much!”
“Your body will conform to mine.”
“N-no, I!”
You choke on your own gasps as he pushes further into you.
There’s more?!
You’re full, obscenely full. A slight bulge pokes from your lower belly where you can only assume he’s sheathed inside of you. He cautiously touches the bulge and you arch your back in response.
“S-sensitive!”
Your nerves are burning. Your temperature is increasing. Everything feels so good. You can hear Malleus growling as his thrusts become more fervid and desperate. His fangs scrape against the shell of your ear as his raspy moans send a shiver down your spine.
“Hah~”
Moans and whimpers slip past your lips as he pushes your legs up over his shoulders. The tentacles on your body match the pace of their owner. They squeeze tighter around your limbs as he squishes you into the wall with such force that you swear you’re going to melt into him and actually become one at this rate. Your hand desperately reaches out and manages to grab onto one of his horns, yanking it with enough force to tell him off, just a bit. He hisses from your action and his eyes narrow when you two make eye contact.
“Careful, beastie.”
His movements are akin to a snake as he slithers back into the little distance you had created.
“My love is not all encompassing.”
Even though he’s balls deep inside of you, you’re about to snap back at him when he decides to shut you up. His mouth taking advantage of yours again and shoving his tongue down your throat. The kiss is anything but sweet. His sharp teeth clash against yours and you eventually taste faint hints of iron in your mouth. He pulls away, only to sink his teeth into the soft skin of your shoulder.
“Ah!”
Whatever pain you felt is quickly overwritten by pleasure as his tentacles seem to continuously multiply to cover nearly every expanse of your skin; squeezing and flicking your sore flesh as one even holds your hair back so Malleus can drink in every single one of your expressions. His cock and your combined fluids harshly slosh in and out of you as they drip onto Malleus’ legs and the inky floor.
Ah, it’s good. It’s really good…
A squeak interrupts your moans when you feel Malleus’ fangs slowly pull out of your flesh before he’s pushing his forehead against yours. Blood covers his lips and he’s staring intently into your eyes. His hand keeps pushing onto the bulge of your stomach and you start to feel weird. Squeamish, ticklish almost. Your toes curl and your nails dig further into his gooey back as he finally releases your wrists..
“I feel weird, Malleus!”
“Let go of your inhibitions. Stay in my arms forever.”
His honeyed words are whispered into your ear, but what makes your pussy throb is the tender kiss he gives your cheek. A stark contrast to how harshly he’s wrecking your body. You let out a scream as you writhe in his arms. Your eyes roll back and your thighs clench as you feel your pussy controlling all of you to buck into his hips.
“Ungh!”
He grunts as you squirt onto his lower half. Your drenched cavern tightens around his dick, making it impossible for him to move an inch. His hand reaches out to steady himself against the wall behind your head as he peppers small kisses on your cheeks, your neck, and forehead while brushing loose strands of your hair out of the way.
“Stay.”
You're dazed but still have enough sense to shake your head.
“Why not? Does this world not please you? I can shape it into the one you came from. I can give you anything and everything. Just stay.”
He's tenderly holding your cheek and forcing you to look at him. A pitiful expression paints his face and you feel yourself nearly compelled to obey. Both of you pant in between words, having exerted far too much in an immoral act.
“Sorry Malleus. I can’t…”
His expression becomes even more heartbreaking before he glowers.
“Fine.”
You feel your body being pulled into the dark ooze covering him.
“Sink into my embrace and awaken small one.”
You feel your throat close up. Panic envelops you for only a second as you descend into the murky slime before opening your eyes and seeing you’re in front of the door you saw earlier. Dark patches of Malleus’ “blot” covers the ceiling and drips onto you.
Did I come out of one of those?
You shake your head.
I just need to get out of here. Wait! My clothes!
You see your clothes next to you. They must’ve sunk through the hole with you. You rush to put your clothes on, afraid of what could happen to you now that Malleus is gone.
Your legs shake as your energy starts to build up again, yet you can’t help but glance around, hoping to catch a glimpse of your stalwart companion. The halls are empty and eerie, devoid of any sign of life except for your own.
Goodbye, Malleus.
You push the door open and rush into a blinding light.
“Hey! Get out of the way!”
Cars honk at you as you stand in the middle of the road and hold up traffic.
“You got cotton in your ears?!”
Another driver yells.
You wince and rub at your eyes before mumbling half-baked apologies and walking in a daze onto the sidewalk.
You’re back. This is your world. You’re sure of it. Nasty attitudes, strange smells, and forever judgemental looks. Yep. This is home. Yet you can’t help but miss Malleus.
Malleus…
Your face erupts into a blush as you think of your final moments with him. You feel yourself getting wet again, or well… You peer down at your legs and see that you’re covered in dark goo. His black ooze was still dripping out of you and it was getting everywhere. In fact, your entire body bore his marks. There were smaller splotches of darkness on your clothes, thankfully, but that was due to change at this rate.
Oh God, it’s turning my legs inky!
You quickly book it to the nearest bus stop, not wanting to deal with the subway again for a very long time after your ordeal. Much to your confusion and relief, no one seems to notice the black gunk that had collected on the floor as they step over it while getting onto the bus. Nor does anyone care of the ooze travelling down your calf and onto the floor of the bus, while the other half of it sticks to your seat.
There’s no fricking way Malleus gave me this much!
Despite most of it being cum, some of it was not, especially the chunk that had collected at the back of your collar. It had been specifically planted onto you, to stay attached to you until you reached your home where it would nestle onto the first mirror it spots. If you wouldn’t stay with him in his world, what choice could he have but to follow you into your own?
