by NyanBerri
Summary

     happen when it makes Mahiru it's target!? We all know where this is
     going... Bad places. Very, very bad places.
     --
     May make more chapters featuring other characters.
Notes
     Soooo... I'm not afraid to admit that tentacles are my number one
     fetish. I've imagined for a long time what it'd be like for plenty of
     Servamp characters to get got by them good ol' tentacles~ I've even
     drawn it too! I'm very proud of that art. I really could've used
     anybody, but I feel like the safest option is Mahiru so he gets to be
     the lucky one! Yay~ ヾ(´∀｀)ﾉ ...I mean, oh no! (´･_･`)
See the end of the work for more notes
Mahiru wasn't sure how he ended up in his current predicament. He just stood in
his room, frozen from shock. In front of him was… something. He wasn't sure how
to describe it. It was like a slimy mass of gray inhuman flesh just laying on
his floor. It kept undulating almost like it was breathing. There were so many
tentacle-like appendages coming out from under it. Mahiru couldn't keep
tracking of all of them since they kept squirming all around. The sound was
practically deafening thanks to the silence of Mahiru’s room. It was a wet,
slippery sound that grossed him out just from hearing it. He wasn't sure how it
got there in his room, but his window was cracked open a bit so the simplest
explanation was that it slithered its way inside from the window. It seemed
obvious to assume that the mass had no bones so slipping through a gap that
small wouldn't be a problem.
Mahiru had to do something about it. It was so gross and he was sure it was
currently making some kind of stain on his bedroom floor. What it was didn't
matter to him, so long as he got rid of it and never had to see it again.
Still, he was too wary of the mass to get close to it. He especially didn't
want to touch it with his hands. He needed something with a long reach,
something like a broom. Mahiru decided he'd have to leave his room to get the
broom. He wasn't sure about leaving the thing alone in his room, but it was
either leave or use his hands, and hands was not an option.
Mahiru slowly backed away towards his door. Taking his eyes off the mass was
certainly a bad idea, so walking backwards was a good precaution. He didn't
know what the mass was capable of doing, if anything at all, so turning his
back to it might be a quick way to get himself killed.
As Mahiru got closer to the door, the mass seemed to have a reaction. It was
like it was violently pulsating and before Mahiru had a chance to react, one of
the tentacles shot out at him. It wrapped around his ankle and felt so cold and
wet against his skin. The slimy feeling made Mahiru absolutely disgusted. He
wanted it off and he wanted it off now.
“Aaah!! Gross, gross, gross, gross, grooooss! Get! Off! Of! Meeee!!” Mahiru
frantically shouted.
He lifted his foot up and shook it around like crazy, hoping the slimy tentacle
would slip off of his ankle. Unfortunately, Mahiru lost his balance and fell to
the ground on his back. It hurt enough that he needed a moment to lay there,
but the creature took it as an opportunity to wrap another tentacle around
Mahiru’s other ankle. Upon feeling even more cold and slipperiness, Mahiru
tried to sit up. He saw that both his legs were restrained and started becoming
scared. The thing had him by both legs. Escape would be almost impossible now.
Still, Mahiru wasn't going down without a fight. He kicked his legs in hopes of
freeing his ankles and flipped himself over so he could crawl away. He managed
to drag himself forward a few inches, but the creature tugged on his ankles and
easily pulled him closer.
“A-aaah!!” Mahiru screamed in surprise.
It flipped him back over and Mahiru began kicking again. He hit the creature
right in the body with his foot and it immediately stopped all movement. Mahiru
wasn't sure what happened to it. Did he kill it that easily? If that was the
case then his legs would have been released. It seemed to rumble a bit and
Mahiru became afraid of what it was about it do. Two of the tentacles suddenly
reached out and wrapped around Mahiru’s wrists. His hands were moved above his
head and pinned down to the floor. His whole body was restrained. He could
squirm all he wanted, but there was no chance of freedom unless the creature
wanted to let him go.
Mahiru was held down without anything else happening for a few moments. He
wiggled his body as much as he could, but wasn't getting anywhere. The moment
Mahiru gave up, another tentacle slowly crept towards him. It slithered over
his pants leg and up to his stomach. The second it went under his shirt and
Mahiru felt the cold and slimy touch, his body reacted causing him to jerk
upward. It tickled in an uncomfortable way and terrified Mahiru about what it
would do to him.
“Ah! Please, no! G-get off me!” Mahiru begged, hoping the creature was capable
of understanding him.
The tentacle continued to slide up Mahiru’s body. It left a thin trail of slime
over his body as it wriggled across his chest. It was so cold and felt
disgusting. It poked out of the collar of his shirt and suddenly Mahiru found
the tip of the tentacle looming right above his face. The wetness made it look
so shiny thanks to the light coming in from his window. Mahiru felt his body
shaking from fear. He couldn't fight back and no one was home so calling for
help would be useless. He could only helplessly watch as the tentacle seemed to
stare at him, wiggling ever so slightly as it slid closer to his face.
“Ahh…” Mahiru quietly whimpered.
All of a sudden, the tentacle lunged at him and forced itself into his mouth.
Mahiru tried to scream, but the tentacle made it impossible for any sound to
come out. The invading appendage was so thick that it filled up Mahiru’s mouth.
He was forced to deal with it sliding across his tongue and he had to taste
what felt like a smooth and wet fish. It went down his throat and he started
choking. He wanted to cough so bad, but the tentacle just wouldn't leave. It
started rapidly shaking in his mouth and throat. It was so violent that the
rest of the tentacle still across his body managed to pop off the buttons of
his shirt, leaving his upper body exposed. The tentacle started to thrust in
and out of his throat but didn't leave his mouth.
Mahiru was beginning to struggle with breathing. He could barely last another
minute before he would risk passing out. His lungs hurt like they were stinging
and he got a tight feeling in his chest. In hopes that it would do something,
anything, Mahiru bit down on the tentacle in his mouth. It violently thrashed
in his mouth and throat before fleeing and returning to the creature’s body.
Mahiru immediately took a big breath of air and coughed over and over again.
There was a lingering taste of the slime in his mouth and it almost made him
want to throw up. His jaw was sore as well from being kept open.
Tears started to well up in Mahiru’s eyes. He just wanted to be let go. His
body was still shaking and he felt so violated. He couldn't muster up the
willpower to fight back.
Another tentacle started to make its way towards him. It looped around his leg
and stopped at his hip. Mahiru shook as much as he could. After what the first
one had done to him, he was scared of what this other one would do. A second
tentacle approached him as well and did the same. It looped around other his
leg and stopped at his hip. The tip of both tentacles snuck into his pants and
Mahiru tensed up, continuing to shake in the hopes that it would do something
to get rid of them. The tentacles around his ankles let go and he felt a wave
of relief rush over himself. It wasn't all of them, but at least two had come
off. Mahiru wasn't prepared for the tentacles in his pants to swiftly pull off
his pants and underwear then wrap themselves around his ankles to re-restrain
him. The tentacles slightly raised his feet up and parted his legs. Mahiru
looked down and his eyes widened. He was fully exposed and on display to the
creature.
“N-no! Please! Don't look! Let me gooo!! P-please!” Mahiru begged.
He tried kicking his legs again, but the tentacles’ grip on his ankles only
tightened and held him more in place. At the very least he wanted to cover
himself. It was just so embarrassing to look at himself like that. To be in
such a compromising position with a slimy creature between his legs. Mahiru
didn't want to accept that he knew what was going to happen to him.
Yet another tentacle emerged from underneath the creature’s body, but this time
it was different looking from the others. It was thin and smaller than the
rest. It reached out and slid across his inner thigh. It was cold and slimy
just like the others. The contact from it made Mahiru shudder. It was slow as
it traveled up his thigh and grazed the underside of his balls. Mahiru
whimpered. The tentacle continued to slide side to side against his balls then
wrapped around them with just a bit of pressure. Mahiru gasped and tried to
keep his mouth shut so he wouldn't moan. He felt himself getting slightly hard
from the slimy touch and it disgusted him.
The tentacle began to slither up higher and around the base of his member. The
cold contact made Mahiru involuntarily thrust his hips. He clenched his jaw to
keep himself quiet. The tentacle coiled around up to the head and pressed its
own tip against Mahiru’s. It was cold and slippery, but Mahiru continued to get
hard in its grasp. The tentacle rubbed against Mahiru’s tip and covered the
head of his member in its sticky slime. He could hear such gross, wet noises
that were even louder thanks to the quietness of his room. It kept pressing
itself against Mahiru, almost like it was playing with him. Mahiru couldn’t
stop himself from feeling turned on. It may have been so icky and disgusting,
but it felt so good too.
Mahiru was getting close, he could feel it. If the tentacle didn't stop soon
then he'd end up coming. He didn't want to come from a disgusting tentacle
touching him. He shut his eyes tight and fought back the need to come best he
could.
Unbeknownst to Mahiru, again another tentacle crept out from under its body. It
was about as thin as a needle. It approached Mahiru and stopped in front of the
tip of his member. The tentacle that was already wrapped around him retreated
so it was just around the base. The smaller tentacle tightly coiled around the
head and nudged up against his tip. A whimper escaped from Mahiru in reaction.
Mahiru’s hips involuntarily thrust upward and he threw his head back as the
tentacle forced itself into his urethra.
“A-a-aaaaah~!! T-take it out! M-make it s-stooop! P-please!” Mahiru pleaded.
It was a feeling that Mahiru didn't know how to describe. He'd never felt
anything like it before and it scared him. He wasn't entirely sure if it hurt
or not, he just knew he wanted it to stop. It was so sudden too that it made
him ready to come, but he couldn't due to the tentacle blocking it. The
tentacle wiggled around and made Mahiru jerk around in response. It created
such a disturbing feeling in his lower gut. He couldn't stop whimpering and
moaning.
The tentacles around his ankles positioned his feet high up near his head and
spread his legs. More of the small tentacles came from the creature’s body. One
of them immediately pressed right up against his entrance. Mahiru felt a chill
run up his spine from how cold it was. It didn't enter, but simply rubbed
against him and yet he let out a loud moan. It felt the tentacle was tickling
him or perhaps testing what his reaction would be. The tentacle then quickly
shoved its way inside Mahiru and squirmed as far in as it could go.
“Aaaa~ahhhh!!” Mahiru screamed.
He felt frozen. He couldn't move as he felt it wriggling all the way inside him
with such force. The movement of both tentacles made his head spin. All of it
was so cold and slippery and just plain gross. He couldn't take it anymore so
he just gave up. Mahiru let out every sound that came from his throat without
any inhibitions and let his hips thrust in any way they wanted to move.
A second tentacle joined the one already inside him. The first one just
slithered around while the second one thrust in and out of him as fast as it
could. A third one soon entered as well, but stayed close to the entrance and
moved very slowly. It pressed itself against the walls of his insides like it
was trying to find another exit. The slimy sounds from all the tentacles in his
body became deafening to Mahiru. All he could hear or think about was the wet
slapping of every tentacle that made its own different movement inside him. The
feeling of pure ecstasy with a hint of unbearable pain was driving Mahiru mad.
Every second that it lasted longer made him want to come more and more, but he
still wasn't allowed to.
The three tentacles suddenly pulled out and Mahiru was brought back to his
senses. He looked down to see the creature’s body slowly lift up. Seeing the
underneath of its body immediately made Mahiru terrified all over again. He
wasn't sure how to explain what he was looking at. The underside had so many
writhing, slimy appendages moving about and collectively it all gave the
illusion of looking insectoid. Mahiru couldn't look away, but the longer he
looked the sicker he felt.
One end of something detached itself from the underside and slid out to loom
over Mahiru. It was so big and very phallic like. It was covered in bumps and
had the same slimy liquid leaking out of the tip. The three small tentacles
went back inside Mahiru just a bit and stretched him open. The larger tentacle
needed assistance to make it inside him after all. He realized the smaller
three were just meant to be the preparation. It crept closer to Mahiru and he
began trying to struggle again. He didn't want that thing to violate him.
“N-nooo!! P-please! D-don't stick it in! It's too big! I don't want it!
Please!!” Mahiru frantically begged.
The tears came back and as he felt it's cold, wet touch against his entrance
the tears started falling down his face. Mahiru whined as the head slowly
entered inside him. The extra help from the smaller tentacles didn't do much,
but he could only imagine how much worse it would hurt if they weren't helping.
He could feel every little bump on the large tentacle rub against his insides
as it slid in. It was like it wasn't stopping. It just kept slowly creeping
further up inside him at a snail’s pace. It was so painfully slow.
It finally came to a stop and Mahiru used the moment to catch his breath. He
felt so stiff from it being inside him. Even the tiniest movement felt like the
worst pain of his life. It only became worse when the tentacle quickly pulled
itself out so barely the head was still inside and forced itself back in all
the way at the same speed.
“Aaaaaaahhhhh!! Out! Out, please! I-I can't… I… don't want… it!! P-p-
pleeeasee!! A-a-ah…” Mahiru loudly cried out.
The tears streamed down his face as he cried and begged for mercy. The creature
either couldn't hear him, or didn't care. It only continued to thrust in and
out of him at a practically violent speed. The three smaller tentacles joined
in and shoved their way back inside Mahiru, acting of their own free will as
they squirmed around with the larger tentacle. Mahiru let out another scream of
pain. In response, another tentacle quickly shot out and wrapped around his
head to cover his mouth and silence Mahiru. Every sound he made was muffled so
he gave up screaming and only let out whimpers and moans as he cried.
It continued on for so long. Mahiru had no idea how long he'd been pinned down
and assaulted for so far. The only saving grace was that the slime coming from
the tentacles made it less painful for them to move around inside him. Mahiru
was still. He didn't move and stopped making any sounds at all. He stared up at
his room’s ceiling and let his mind go blank. He didn't care about the pain
anymore, no matter how much it hurt. He just wanted to get it over with as soon
as possible. Although, he wasn't sure when that would be.
All of a sudden, all the tentacles stopped moving. Mahiru felt relieved. It was
still painful with all of them inside him, but at least it wasn't nearly as bad
with them not moving. He immediately regretted that feeling when it felt like
the larger tentacle rumbled and it suddenly filled him up with such a copious
amount of slime. It kept ejaculating to the point that the slime was seeping
out of Mahiru and falling in every direction. It was practically freezing and
felt like gel as it pooled onto his stomach and the floor around him. The
tiniest tentacle that was still in his urethra finally pulled out. It was like
unclogging a running faucet as Mahiru moaned louder than ever before against
the tentacle covering his mouth and came all over his own chest.
The smaller tentacles then pulled out as well, easing the pain he was feeling.
The largest one stayed for a moment longer before slowly sliding out followed
by much of the slime. It retreated back underneath the creature’s body before
all the rest of them released Mahiru and went back as well. He put his legs
back down and let himself lay flat on the floor, panting as he tried to calm
down his rapidly beating heart. He was glad the major pain was finally gone,
but his entire body was sore, cold, and sticky.
He glanced back down to the creature. It was trying to get away by climbing up
to the window. Mahiru couldn't bring himself to move. Everything hurt too much.
He just looked away and tried to block out the disgusting sounds of it moving.
As it left, Mahiru wondered if that was all it wanted. Just to completely and
utterly violate him then leave. Had it done something more to him that he
didn't know about? He had no way of knowing. It was too difficult to focus on
any one particular thought at the moment.
It started setting in for him exactly what just happened to him. Mahiru let out
a few choked sobs before covering his face with his arms and completely
breaking down as he uncontrollably cried on his bedroom floor.
End Notes
     I would loooove to write more of these if it's something people would
     want. I don't want them to be repetitive though. I'd like any others
     I write to be with characters that could really add personality to
     the fic. I think a different tentacle monster in each one would be
     fun too so it doesn't become boring with the same monster doing the
     same stuff every time. I already have an idea for a really cute one
     that would be good with a certain character that I won't name! (　^ω^)
     I know the monster here was pretty scary I guess, so having a cute
     one instead would be a nice change. Plus they're my favorite kind
     when they're just so small and cute~ (///▽///)
