Maybe a Ghost Did It?

Summary:

So Izuku's house was haunted and they even named the ghost Kacchan. Everything that couldn't be explained rationally, it was Kacchan's doing.

"You think I'm getting beat up in my sleep by a ghost?" Izuku questions

"That or you are getting your back blown out"

Izuku squawks "M-MY BACK BLOWN OUT? BY A GHOS?!"

"How else do you explain the lower back pain? Are you sore?"

Notes:

Does fucking a ghost count as monster fucking?

N e ways! Happy reading!

Work Text:

Izuku's alarm screams loudly at him, he groans. Izuku feels like death, he had gone to bed early and yet he feels like he hasn't gotten any sleep.

 

Could he be getting sick? That was possible, the weather kept drastically changing, it's enough to make anyone sick.

 

Pressing a hand to his forehead, he sighs.

 

No fever. Not sick.

 

Wincing as he got up and padded to his bathroom, Izuku felt a sharp pain in his lower back. Looking in the mirror he had bruises there.

 

"What the hell" he says to himself

 

Izuku is clumsy, it is a well known fact. He is embarrassingly clumsy and has had bruises in the most randomest places from fighting the floor, getting jumped by both the coffee table and wall in the dead of night.

 

He usually can place when and where he got a bruise but lately Izuku was having the hardest time pin pointing the ones in his back, hips and thighs. Shaking his head, Izuku started his routine to get ready for the day.

 

Work is tiring and doesn't help his back that he has to do heavy lifting when new orders come in at the store. His lunch break couldn't have come fast enough, he sits in the break room with his coworker and friend Ochako.

 

"Man" she starts pointing her fork at him "You look like shit"

 

Izuku sighs "I feel like it"

 

"I keep telling you to get a better sleep schedule"

 

"I HAVE! I swear! I just- I don't know. I've been waking up with back pains and bruises that I don't remember getting"

 

"You are clumsy"

 

"Yeah but like what can I possibly be? Bumping into and hitting to get bruises in my hips and thighs?"

 

Ochako pauses before shrugging "maybe the ghost did it?"

 

It was a running joke that Izuku's apartment was haunted. A lot of unexplainable things had happened in his house, cabinets opening. Lights being turned on, footsteps being heard in the night when no one was around.

 

So Izuku's house was haunted and they even named the ghost Kacchan. Everything that couldn't be explained rationally, it was Kacchan's doing.

 

"You think I'm getting beat up in my sleep by a ghost?" Izuku questions

 

"That or you are getting your back blown out"

 

Izuku squawks "M-MY BACK BLOWN OUT? BY A GHOS?!"

 

"How else do you explain the lower back pain? Are you sore?"

 

Izuku wasn't sure if he was, the pain in his back overpowering anything else he might feel. But it was ludicrous to think that a ghost? I mean Izuku wasn't even sure if his house was haunted.

 

How could a ghost even?

 

Oh gods. Izuku can feel a headache coming just trying to comprehend it. So he doesn't try, he leaves the thought alone.

 

When Izuku arrived home and walked into his kitchen, three cabinets were open. Izuku squints staring at them, unsure if he had left them like that in a rush to make it to work on time in the morning.

 

He shrugs closing them and calls "Kacchan please close the cabinets when you are done"

 

He didnt get a response of course he didnt, he is talking to a ghost. A ghost that may or may not really be there. After that though, Izuku got this unsettling feeling was being watched.

 

Especially as he showered.

 

Izuku scrubs soap into every dip and curve of his body, massaging his aching muscles and groaning at the feeling as his muscles begin to relax. From the corner of his eye, through his shower door, he swears he sees a shadow standing in the doorway of his bathroom.

 

So he opens it, to find no one is there.

 

Izuku shrugs and hums to himself finishing his shower. He wraps a towel around his waist and heads to his bedroom to get ready for bed.

 

When Izuku's bruises and back pain had finally gone away and surprisingly he hadn't found any more random bruises. Izuku was happy, he had gotten proper sleep too.

 

Today was Izuku's day off, so he spends time cleaning up his apartment and running errands. After he was done, Izuku laid bored in his bed. Idly running his hand up and down his exposed stomach.

 

Up and down.

 

Izuku runs his fingers along the band of his underwear. He isn't feeling particularly horny but it's one of those boredom things, where you have nothing better to do then jerk off. So Izuku grabs his lube and his favorite dildo.

 

Shimming out of his boxers, squirting a little bit of lube in his fingers, warming it up before circling his entrance. Izuku slowly works his finger into the knuckle, it has been a while but he is surprised to find little to no resistance.

 

Almost as if he had done this recently.

 

For a moment he thinks maybe Ochako is right but then the thought leaves when he enters a second finger. Izuku begins to thrust his fingers until they aren't enough. Lubing up the dildo, Izuku slowly pushes it in and can't help the high keen whine that escapes.

 

Maybe he should get on one of those hook up apps. He /needs/ to get laid.

 

Izuku flips on his stomach and thrusts the dildo in just at the right angle.

 

"Fuck" he curses and hits the spot over and over again.

 

Izuku does his best to wrap his hand around his cock moving his hands in time with how he thrust the dildo into his ass.

 

While Izuku indulges in his play time. He doesn't notice the shadow that stands in the corner of his room. Biting their  bottom lip and enjoying the show.

 

That night Izuku dreams of an adonis of a man, sharp fiery red eyes and ash blonde hair and sexy grin.

 

"Yeah just like that Izuku" The man says, thrusting his hips "You take me so well, you were made for this weren't you?"

 

Izuku whines in his dreams. It feels all too real. That monster cock he can practically feel it in his throat, but Izuku whines for more.

"More, give me more" Izuku breathes

 

Then Izuku is bent in half and fucked into with pure abandon. 

 

Izuku wakes up, the next day sore and with bruises. Oh and horny as hell, just who the fuck is that god like man?

 

This happens for the next few nights, and Kacchan has been more active around the house. That feeling of being watched never leaves Izuku unless he is out of the house.

 

"I dont know whats happening" Izuku whines to Ochako over the phone

 

"Im seriously thinking your house is haunted. And you really are being fucked by ghost" She says

 

"Ochako! Not this again" Izuku hides his face in his pillow "how would i even find that out?"

 

"I don't know? Pretend to be asleep and see what happens"

 

"And if nothing happens?"

 

"Then your house isnt haunted and you arent being fucked by a ghost? You are just clumsy and keep forgetting that you are doing things in your house?"

 

Izuku hums, the idea doesn't sound too bad, but it does sound a bit wild.

 

"Im not doing that" Izuku says

 

"Okay"

 

With that they hang up. Izuku ponders the idea again, it would be nice to get to the bottom of things.

 

He is just thinking about it... he isnt gonna do it.

 

Izuku had decided he was gonna do it. Its not like he was really being fucked by ghost. I mean come on, do you hear how crazy that sounds? What is this? A Movie? Is this scary movie two? Haunted house?

 

No this is real life and Izuku is not being fucked by a ghost.

 

When bed time comes, Izuku does his nighttime routine and if he decided to give the "ghost" a little show before bed that his business and no one else's, those dreams of the ash blonde were perfect spank bank material forgive him okay?

 

Then Izuku waits... and waits and waits. It's nearly three am when Izuku is about to give up and just actually sleep, when he hears a floorboard just outside his room creak. Soft patter of feet hitting the rug of his room but he knows no one is there because the door didn't even open.

 

There's a cold caress to his face and Izuku does his best not to move or flinch even.

 

"You are such a tease ya know?" The voice says to Izuku's surprise it sounds /exactly/ as the man from Izuku's dreams.

 

Could... could those dreams? Not have been dreams?

 

Izuku's covers are yanked off him and he tries not to flinch, he is supposed to be asleep after all. The cold caress is back, it's definitely hands touching him, slowly touching him, his ankles. Izuku is flipped effortlessly on his back, his bed creaks and he feels it dip with weight.

 

"Fucking yourself on that fake dick like that" The man because that raspy deep tone cant be anything other than a man.

 

The hands travel slowly, from his ankles to caress his thighs.

 

"You are so fucking hot. You drive me insane" fingers find their way under Izuku's shorts "Walking around in these little ass shorts that barely contain your fat ass"

 

Izuku so badly wants to pop an eye open to see who or what is there but it's too soon. The cold hands creep from under his shorts to the hem of them and yank, exposing him to the cold air of his room.

 

Izuku feels like he should feel some kind of shame because he has a semi. Only because of the voice, it matches perfectly to the one in his sex dreams.

 

"So pretty" the voice murmurs, running cold fingers up Izuku's shaft to the tip and then back down.

 

Izuku shudders, he didn't mean to but the touch was familiar and foreign all at once. Though the owner of the voice didn't seem to notice that or he ignored it all together.

 

Soon Izuku's legs were spread wide and he could feel the heated stare of the other. Then Izuku felt it, a cold wet swipe in his pink little hole, it was one swipe rather than two.

 

He couldn't help his whimper. 

"So responsive tonight" The voice says "i wanna hear all your little noises baby"

 

Izuku's cheeks spread and he, gets ate out like he is a last meal. He can't help the moans that escape him, it feels so good especially when the wet cold tongue circles his rim before plunging it.

 

"You like that don't you? Of course you do" The voice says before licking his hole to his balls, shaft then the tip of his dick.

 

Izuku's hips buck up, seeking more. A dark chuckle fills the room before Izuku cock is swallowed down. The mouth, even though it feels cold, feels so good, Izuku had to fight the urge to grip his bed sheets.

 

Izuku gasps when a finger slides into him and his eyes shoot open when that single finger presses against his prostate. He looks down and there his eyes meet red, the same red from his dreams.

 

The person? Can Izuku even call him that? He is almost see-through, almost.  The ghost? Comes off Izuku with a lewd pop

 

"I knew you were awake little shit" He says

 

Izuku tilts his head, Kacchan is real.

 

Kacchan. Is. Real.

 

Holy shit.

 

And Ochako was right. Izuku has been getting fucked by ghost.

 

What. The. Fuck.

 

"Kacchan?" Izuku questions

 

"Yeah yeah, here ya go with that stupid childish nickname" The ghost sits up, his finger still seated in Izuku's ass "it's me. Kacchan"

 

Izuku's eyes go wide and his mouth opens and closes like a fish. Izuku isn't sure what to do or say.

 

"Why" Izuku finally asks after a few minutes of silence and staring.

 

"Why what?"

 

"WHY ARE YOU FUCKING ME IN MY SLEEP?"

 

Kacchan stares before shrugs "why not?"

 

Izuku sputters "Why not? Why not? BECAUSE YOU ARE VIOLATING ME!?"

 

Kacchan thrusts another finger into Izuku and he moans "Really? 'Cause you don't seem mind"

 

"T-thats not fair"

 

Kacchan smirks and leans over Izuku so their noses brush "Yeah? You think I dont know you fucked yourself on that dildo for me hah? You think that was fair"

 

"I- i was horny"

 

"Yeah well so am i" Kacchan leans back and his cock is out and laying against Izuku's.

 

It's bigger than Izuku's. How is that even possible? He isn't even alive.

 

"So how about we help each other out huh? Scratch my back? I scratch yours? I know ill feel better than the little fake cock of yours"

 

Izuku stares and stares. Kacchan already has his fingers in his ass, which now that Izuku thinks about it.

 

How the fuck?

 

But anyways, they are already like... half way there... might as well... ya know?

 

A nut for a nut.

 

"Fine" Izuku says "But after this you /cant/ do it again"

 

"Sure" Kacchan rolls his eyes and thrusts his fingers again.

 

"How is this even possible?" Izuku moans when Kacchan enters a third finger

 

"Its the witching hour. That's how."

 

Izuku glances at the clock that read 3:10 am

 

Ah, he can guess that makes sense.

Kacchan's fingers curl and hit all the right places. Izuku is panting and his body feels hot even though something so cold is pressed against him and in him.

 

"Please" Izuku begs

 

"Begging already? Jeez you really want my cock don't you?"

 

"Ive been dreaming about it" Izuku murmurs blush coating his cheeks

 

Kacchan lines himself up and slowly pushes himself inside. "Aint dreams Deku"

 

Twin groans fill the room and then and only then does Izuku realize.

 

No he hasn't been dreaming. It all has been real.

 

His dreams. Weren't dreams at all.

 

Kacchan slowly thrust in and out, Izuku sucking him with a vice-like grip.

 

"Shit. How are you still so tight?"

 

"Move faster"

 

Kacchan smirks down at izuku "Need it faster?"

 

"Yes... please"

 

Kacchan adjusts Izuku's legs over his arms and starts to thrust rough and hard. Izuku moans loudly, how can something.... how can someone who is barely physically there feel so good?

 

Make him feel so full.

 

"Oh fuck oh fuck" Izuku curses hand behind him pressed against the head board to keep from hitting it.

 

"Feel good don't you? I can always make ya feel good"

 

"Yes yes please. More more"

 

And more Kacchan gives, wrapping Izuku's legs around his waist. Dropping his weight to his forearms, pulling Izuku in for a heated- er cold kiss?

 

Their tongues dance together, Izuku moans and Kacchan eats up all of his moans. Izuku takes the opportunity as he sucks on Kacchan's tongue to flip them. He pulls away, throwing his head back as Kacchan hits a different, better angle this way.

 

"How can I feel so hot and yet you are so cold?"

 

"Cause im dead dumbass"

 

Izuku hums and his nails dig into Kacchan's chest as he bounces.

 

"Fuuuu" Kacchan groans, his hands finding Izuku's hips and squeezing

 

Well that makes sense how he has bruises there.

 

Kacchan's heels dig into the mattress as he thrust up at the same time Izuku comes down. Izuku's eyes cross and his tongue is lolling out his mouth. Kacchan pinches and pulls at his nipples making Izuku let out a high, keen moan.

 

"I dont think im gonna last" Kacchan says

 

"Cum in me please please fill me out"

 

"Gods you are such a slut when you are awake" Kacchan says as he flips them again.

 

Kacchan bends Izuku in half and drills into him. Izuku's nails dig into his biceps and he is screaming

 

"Kacchan kacchan" over and over again

 

Kacchan wraps his hand around Izuku's dick and starts pumping "cum with me"

 

With a few more pumps and thrust of Kacchan's hips. They come together, Kacchan collapses on Izuku but he doesn't feel all that heavy. Heavy breathing fills the room.

 

"Im so glad i was awake" Izuku says breathlessly

 

"Yeah? Me too. Should be awake for next time"

 

"Kacchan. I said not to do it again"

 

"Its Katsuki"

 

"What?"

 

"My name is Katsuki" Kac- Katsuki peers up at Izuku from his spot on the greenette's chest

 

"Hi Katsuki. Im Izuku"

 

"Yeah i know" Katsuki closes his eyes

 

"Im serious" Izuku says

 

"Yeah yeah. Dont fuck you while you sleep."

 

"Please don't leave cabinets open either"

 

"THAT AINT ME! THATS YOU. IM THE ONE THAT CLOSES ALL YOUR SHIT AND CLEANS UP AFTER YOU"

 

Izuku blushes "Ah really? Thankyou"

 

" 'S nothing" Katsuki mutters "You look tired whenever you come home... its the least i can do... since ya know... you aint ask me to leave or nothing"

 

"You aren't really a bother" Izuku says "A pleasant ghost roommate... minus the ya know in my sleep which seriously stop, doing it in my sleep. That's not okay"

 

"You didn't seem mind"

 

"BECAUSE I WAS ASLEEP?"

 

"What if you are awake then?"

 

"Huh?"

 

Katsuki sits up with a smirk "you said not to when you are asleep... What if you are awake? Can i fuck you then?"

 

Izuku stares at the ghost and actually ponders the idea. This was really /great/ sex, what could possibly go wrong?

 

"Okay. Only if im awake"

 

"Deal".

 

And so Katsuki got what he wanted and Izuku found out what was going on with him plus crazy sex.

 

"Hey izuku. Did you ever find out you were getting those bruises?" Ochako questions a month later when she is over Izuku's house.


Izuku nods and his eyes dart to the corner of the room, where Katsuki stands with a smirk. "Yeah... Im just clumsy"
