Author's Note

Yep, this is happening. I literally woke up one morning with a few hours left before work, thought of Monster Musume, and this happened.

I really really want to write this, and any and all suggestions, ideas and story info would be much appreciated.

LEGEND BELOW

"I love you." = Normal speech.

''He can't hold back forever...'' = Thoughts.

"Well… Now I really wish I went with them…" A soft male voice muttered, staring listlessly at the ceiling above. The young man glanced around the large empty room he found himself in, devoid of life except for him. The same could be said for the rest of his house.

It was his parents house specifically, as well as his. He lived with his family only because it was easier to, and more then that, his parents were never home. As proud business men, and women, they almost never had the free time to actually return home.

So you could say, in the end, it was actually just his house. Kurusu Kimihito, the sole occupant to the largest house on the entire block, and son to a well set family.

"Oh well… That's not going to change I guess…" The young man yawned out, pulling himself out of bed. His lightly tanned skin and fair complexion contrasted wonderfully with his sharp jawline and handsome face.

He yawned again, exposing his set of sharpened fangs and glowing dark crimson, almost brown eyes, marked by black sclera. He scratched lightly at his head of wild yet tamed head of black hair, being careful to avoid the two large horns that framed his head.

As he stood up from his bed, dressed in nothing more then his underwear, he stretched long and hard. His wings unfurled behind him, large and bat-like in design. A long thin black tail wagged slightly behind him, the man careful of hitting the unbelievably sensitive heart shaped tip against anything.

He blinked slowly, trying to wake himself up. As a male succubus, something he got from his mother's side, he struggled to get out of bed every morning. His long pointed ears twitched at the sound of his neighbors car leaving their driveway.

"I-It's so cold…" He muttered, shaking as he left his room, quickly making his way through the hall and into the large open living room. This early in the morning was freezing, and his father must have set the damn AC on cold just to play with him.

"D-Damn him.." Kimihito muttered, cranking the dial on the thermostat up high. It would take a couple hours before the heat really filled the house, but he'd live.

It was still early in the morning, and he had plenty of time left before he needed to get started on his online class. Today was his day off too, so besides class, he had little to do…

An hour later saw the succubus sitting on the couch, wrapped up in a warm morning robe. He was casually flashing through the local channels, passing by the news and half the random entertainment channels before he paused on the music channel.

"-orld's first idol band consisting of nothing but Asian subspecies are topping the charts! Ever since the cultural species exchange bill got passed, they've been rising to the t-"

He tuned it all out, having left the couch and robe behind in favor of making himself breakfast. He threw an apron over himself. With the house having finally warmed up, he found no reason to dress in anything but the bare minimum, underwear and an apron.

He found it way more comforting that way. Tail wagging behind him and wings stretched out wide behind him, he smiled lightly as he sang along with the music playing around him.

Yes, it was just another normal morning for the supposedly unreal half human monster boy.

Oh, perhaps I didn't mention it previously.

In his world, up until a few years ago, the world governments had hidden away the very existence of monsters. Specifically, the existence of all the different species of monster girls. All monsters were almost inherently female, with rare exceptions. But Succubi were inherently female, no working around that fact.

There were beasts, but that was a whole separate ball game.

But roughly a few years ago a new bill was passed, a bill that allowed the separate kinds to interact with one another.

It was still in the early stages, and there were many laws regarding them. But despite that, monster girls had truly begun to integrate into normal human society fairly well, all things considered.

Now, with the whole thing about them being distinctly female, you might have a question.

Or two. Two's fine.

Why was Kimihito a succubus? And the most important question, why was he male and a succubus?

He had a perfectly reasonable answer to that question.

He didn't know. He'd never even seen a monster girl in real life up until a few years ago.

Was something like this supposed to be possible? No, no it was not. But that didn't change the fact that he was in fact, quite real.

His succubus dna had posed quite the challenge in life. The whole reason he had done schooling online was his difficultly when dealing with practically anyone. He wasn't overly shy, but he struggled with controlling his dna when it decided to freak out in public situations.

Accidentally seducing normal humans, yep.

Turning normal people into horny crazed messes with a simple touch, despite gender? Every time.

Having normal people profess their love for him, and offering to have his babies? Yeah, maybe not as often, but that had definitely happened enough times to become a problem.

But he didn't want any of that. He didn't want to use his powers to abuse people for his benefit, and it was so hard, because after some point in his life he started questioning if the people he associated with were friends because they liked him. Or if they too were cast under his spell.

Sometimes he was awake for hours at night, thinking about that potential reality.

But he'd learned to deal with his abilities as he grew older, and they weren't as out of control as they were when he was a child.

Furthermore, being half human allowed for him to hide his monster heritage, albeit not permanently. That was why he was able to go about his day in the real world, and no one knew a thing about his succubus nature. His mother always told him to hide his heritage as best he could, knowing what life he could live if people found out.

And if he could manage, he'd like to keep it that way for as long as possible. He really didn't want that kind of…

Attention…

"There we go." He smiled to himself, the full plate of pancakes he'd cooked up looking as delicious as the last time he made them.

He sauntered over to his kitchen table, taking a seat at the far end. Not for the first time he wished that this massive house he called home wasn't so empty…

He took one single bite, before he was interrupted.

(Knock Knock Knock)

He nearly choked on his food, slamming his hands onto the table. He took a huge gasp of air, glancing at his front door? "Who in the world?"

With his food left behind, he got up from the table, quickly moving towards the front door. He pressed his face against the peephole, spotting an unrecognizable face.

She was a tall woman, probably of asian descent. Long black hair, a tight and very sharp business suit. More then that, she was hot.

He cleared his throat, and focused hard. His horns regressed into his head, as well as his wings. His tail stayed, instead wrapped around his waist like a belt. His eyes lost the glow and the black sclera, and his fangs and ears returned to a normal look. His claws also reverted to normal human fingernails. He cleared his throat, before opening the door slightly, peeking his head out.

"Uh… Can I help you?" He asked slowly, nervously staring the woman down.

The grin previously on the woman's face widened as she pushed her glasses up.

"Good morning mister Kimihiki, I have brought Miia with me. I hope you took all that time preparing a room for her." The business women spoke up, motioning to the girl beside her.

Although calling her a girl wouldn't be doing her justice. She was gorgeous, probably only eighteen or nineteen years old, and similarly of asian descent. The entire lower half of her body was that of a red snake, easily being seven times the length of her body, covered in silky smooth red scales. Her ears were long and pointed, and red as well, much like her long red locks of hair. The upper half of her body that was mostly human was covered in a cute dress that did little to hide her huge chest.

And her eyes, sharp golden in color and slitted like a snake's, were nervously glancing at and away from him.

This girl, Miia, was a Lamia. A monster girl subspecies that was part snake in body.

"I-Umm. Good morning, s-sir! I hope that we can live together happily!" Miia spoke up, offering him a quick bow out of respect.

"Wh-huh. Uh-" Kimihito managed, mouth opening and closing in shock.

"You did talk that time to read ahead on all the laws you'll need to obey, right?" The lady asked, smirking at him. "After all, I don't think you'd want to accidentally break them and send this poor girl back to her homeland…"

"W-Wait-" He tried jumping in.

"You'd end up in jail too. So yeah, no sex. Not even foreplay." She stated as if it were obvious.

"Hold on-"

"Yeah sorry, no bending those rules. Don't even ask." She cut him off again.

"B-But.. That's not wh-"

"Oh! Also! I almost forgot, silly me!" She jumped, pulling an important looking document from somewhere. Before he knew it he was holding it and signing it, almost on autopilot.

"Perfect! That makes you liable in case anything happens to her. Trust me boy, you'd better not go behind my back and seal the deal with her!" She wiggled her eyebrows suggestively.

"Wait please! Hold on a second…"

"Sorry, but I'm on a tight schedule. You take great care of Miia now! And trust me, if you don't!" She pulled down her shades, looking suddenly very menacing. "I'll know about it."

Without saying anything else, the woman quickly hopped back into her black car and sped off.

Kimihito stared nervously at the space where she just was, before slowing turning to the shy yet happy looking Lamia. Miia didn't have much with her besides a single suitcase and the clothes on her body, and she quickly lugged it inside.

The half succubus found himself stepping out of the way as the girl eagerly entered, eyes wide as she took in her new place of residence.

"Wow, mister Kimihiki! Your house is really big!" Miia exclaimed in joy, eyes sparkling.

"Uh.. It's Kimihito.." He corrected lightly. The girl blinked, before smiling.

The Lamia turned back to him with an exasperated expression. "I'm sorry about miss Smith, she can't seem to even get names right! She's a bit of a hassle, but she's nice once you get to know her." She assured with an easy smile.

"Uh-huh…" He muttered in a daze, blinking slowly. He glanced down, eyeing the large thick red tail that followed the girl as she slithered into his house, his cheeks turning red. She vanished into his kitchen, setting her stuff by the table.

''What the hell is happening?!'' He questioned mentally, eyes twitching. He took a second to do a few long breathing exercises, trying to calm his racing heart down.

He could hear Miia shuffling around in his kitchen, probably unpacking her things. He glanced down to the papers in his hands, slowly taking it all in.

It was the form for the cultural exchange program, listing him as a new host for the Lamia in the other room. It had a couple random blurbs of senseless conjecture, and nothing really useful.

Now, of course, if he had even an inkling as to what the hell just happened, he might have been a little calmer. That being said, he didn't remember ever signing up to be a host for the exchange program…

"Kimihito sir! Are you sure you should be dressed up like that?" He jumped at the sound, spotting Miia staring at him from the corner of his eye. He glanced down, taking in his current state of dress.

"It's very cold outside." The girl muttered, her cheeks turning a very healthy shade of red as she eyed him with a gaze he had never seen before. "O-Of course, you don't have to change if you don't want to…" She muttered.

He felt as if he was being eaten by her eyes, and quickly muttered an excuse before vanishing upstairs to his room. He was in dressed in his casuals so fast you couldn't have been sure he wasn't always wearing them.

He collapsed against his bedroom door, rubbing his temples to sooth the oncoming headache.

"What just happened…?" He asked out loud, staring at the far side of his room. He was tricked! He never signed up for this! Damn that woman…

Perhaps miss Smith just got the wrong house? Yeah, that's probably what happened. He just needed to go downstairs and tell Miia that she had the wrong guy!

But wait… didn't he sign something saying he'd take her in..?

He needed to think about this.

"Okay.. Okay…" He sucked in a deep breath through his nose, before slowly letting it out. He opened the door, making his way back downstairs. He stopped just short of the kitchen, the sound of Miia nervously shuffling back and forth catching his ears.

"O-Oh… I hopped this wouldn't happen again… They never like Lamia's… How could they…?" He could hear Miia muttering quietly to herself, sounding almost as if she was about to cry. He stopped moving, listening instead.

"Miss Smith said that he was the last chance… No one else will take me…" She whispered, rubbing at her face. "Mother will be so disappointed in me…"

She sounded so sad, so defeated…

He sighed…

Well, there went that option. Who was he if he left this girl behind in the dust if he could help it?

He was so weak when it came to women, and the sound of her on the verge of tears lit a fire on his plans to call this Miss Smith and have her take Miia away. Did the fact that he had never once before seen this girl in his life affect his choice?

No. No, no it did not…

He stepped back into the room, gently catching the snake girl's attention once more.

"H-Hey uh… Miia?" He spoke up. The girl jumped, wiping away her tears.

"O-Oh! Kimihito sir! I-I didn't hear you come back down…"

"Hey, I'm sorry if I left you with the wrong impression." He apologized genuinely, rubbing the back of his neck. "I didn't mean to scare you like that, I was just a little bit… overwhelmed." He sighed, head lowered.

Miia sniffed. "Overwhelmed? But I thought you knew I was coming…?" She questioned quietly.

"Yeah. I uh, there seems to have been a mistake." He started. Miia was visibly shivering, and he had a feeling it wasn't from this conversation. "Here, you look like you're freezing!" He worried, quickly tracking down a large blanket. It wasn't big enough to cover her entire lower half, nothing probably was, but it was something.

Miia's eyes started almost tearing up, a genuine smile breaking out on her face.

"Thank you Kimihito." She expressed genuinely, smiling. The young man stood back, rubbing the back of his head nervously.

"So, I never signed up for the exchange program…" He stated truthfully. "There must have been a mix up… I'm sorry I didn't say that when Miss Smith was here…" Her eyes widened, and tears started to fall. His composure faultered, as he waved his hands frantically.

"B-But! That doesn't mean I'm not up for it! If you still want to stay, even knowing I'm probably not the guy you were really looking forward to… you are completely welcome here." He hastily jumped in, the sight of her crying setting a fire in his heart. "If that's okay with you, this can be your place too." He stated seriously, eyes locked with hers.

She stopped, a small hiccup escaping her. She eyed him suddenly in a different light, relief filling her body. "R-Really? You mean it?" She almost didn't believe it. He smiled at her, his handsome features finally registering in her mind.

He didn't know her, never met her before. He didn't sign up for this, and her just being here probably ruined any plans he had for the future, but he would accept her if it meant she was happy. For a man she just met only half an hour ago, he had to have been the nicest man in her entire world.

"Yes." He suddenly found himself pinned to the ground underneath her powerful snake body. "Woah woah!? M-Miia?!"

The snake girl started smothering him with her bosom, cooing happily. He grunted, trying to gently escape. But his attempts were futile, as her thick snake body proved much too powerful for him.

"Oh thank you thank you thank you!" She chanted, totally overjoyed. "Kimihito sir! You won't regret this!" She promised, eyes sparkling. His eyes softened, an easygoing grin marking his handsome face.

"It's uh.. you can just call me Kimihito… or anything else you want really…" He said, trailing off. Her eyes gained a glint, a beaming smile lighting up her face.

"Okay then… Darling." She purred, rubbing her face against his own. She couldn't have been more pleased. He was prime husband material! His expression fell, not that she could see..

''Darling, huh?'' He thought with a sigh. ''Oh well, it's not bad actually…'' He dropped his head back down, staring up at the ceiling. As he lay there, being practically hugged to death by this beautiful Lamia girl he literally just met ten minutes ago, he couldn't help but feel how strange his day had gone.

Three hours ago he thought it was going to be horribly boring without anyone else in the house. He supposed that the worry of his was blown away by the girl that mounted him…

Was it worrying that his first response to this was the desire to go back to bed and sleep…?

He yawned, apparently surprising the Lamia above him. He honestly hadn't gotten any good sleep last night, and it was really coming back to bite him. "Hey Miia?"

"Yes Darling?" She responded happily.

"I know you're probably excited to be moving in, and that's great and all but…" A yawn suddenly broke his train of thought. "I'm kinda feeling tired, and I should probably give this stuff a read over, otherwise I might go to jail…" He muttered with a tired laugh, waving the forms he signed earlier in his hand.

She stared at him in surprise, before smiling. After probably ten minutes of bouncy snuggling, she finally let him free. Although, "You're very warm, Darling. As a Lamia, I struggle to stay warm…" She cooed softly, hugging him. He was abnormally warm, and she found that out very quickly.

Kimihito stood to his feet with a yawn, smiling at the beautiful girl before him. "Since this is a sorta… surprise visit, you'll have to excuse the lack of preparations I've made. I don't have a room set up for you, but there is a guest room down the hall." Following his explanation he pointed to a door off to the side, down the main hall.

"Oh, thank you Darling!" Miia exclaimed, already moving to truly get set in. He smiled, and seeing as she had busied herself with that, he turned and casually made his way back upstairs.

However, in his lack of attentiveness due to his lack of sleep, he failed to keep his tail wrapped around his waist. The long black appendage was lightly wagging behind him as he sauntered upstairs, and that was what Miia just so happened to see as he disappeared into his bedroom.

The Lamia's brain slowed to a crawl, golden eyes blinking rapidly as she stared his rear end down with a calculating eye.

Did she just see what she thought she did?

No. Obviously she didn't. Because that wouldn't make sense.

Why would her host have a heart tipped tail extending from his backside? Surely she was seeing things…

She shook her head, trying to clear the image from her mind as she instead focused on setting up in her new room. After all, this was her first true big day in Japan under her handsome new host.

She slithered away, deciding to take the time to explore her new home...

The door to Kimihito's room shut with a light click, the half human collapsing onto his computer desk's chair. His mind was still reeling, but he had practically excepted it by now.

One thing did stand out to him however. Miia seemed totally unaffected by his powers, seeing as they had complete physical contact and she didn't react whatsoever.

"Thank god… it doesn't effect other monster girls…" That was a huge relief off his shoulders. He'd never gotten the chance to test it out on a monster girl, most likely due to the fact that they only started popping up in the country a few years ago. Personally, he was afraid to. But it seemed like his worries were finally put to rest.

That being said. "What the heck was Smith thinking…? Shouldn't this stuff be covered more?" He honestly had no idea how she could just practically throw Miia at him like that. What if he was a crazy person? How was Smith supposed to assure Miia's safety if they had the wrong guy?

The idea of the cute girl downstairs accidentally being thrust into a sketchy situation with strangers upset him more then he thought it would.

"Gah… I'm done thinking about it…" He muttered, rubbing his sore temples.

Honestly, this strange turn of events could actually turn out great. He was already preparing to live a boring life alone with his parents gone, but with Miia here, he was sure things would be picking up from here on out.

Just one problem…

"I-I… can't…" He grunted underneath his breath, and unable to hold it any longer, his human form broke. He managed to get his shirt off before his wings sprung from his back, his horns similarly appearing, crowning the sides of his head. His fingernails grew into claws and the sclera of his eyes turned black, his crimson orbs glowing in the dim light of his room. He ran his long pointed tongue over his suddenly sharpened fangs, mind drawing a blank.

"Ah… huh… Well then." He sighed. He could usually hold that form for hours on end, but either his lack of sleep or close contact with another monster girl threw his control off. He honestly didn't know.

"There's no way I can hide this from Miia…" He sighed, moving to pick up his shirt. "But I can't have people finding out… That'll make things way too difficult…"

"Darling? Are you okay in there?" He nearly jumped out of his skin at the sound of Miia's voice, forcing his human form back on. The Lamia entered the room, finding her host at his computer desk calmly reading over the forms Smith gave him.

"O-Oh, hi Miia. Did you need something?" He asked, somehow managing to keep his composure. He glanced at the snake girl from the side of his eyes, refusing to look at her fully. In his haste, he was unable to fully revert, his eyes still succubus in nature.

The Lamia glanced at him in concern, giving him a once over before shaking her head. "Oh, it's nothing Darling. I just thought I should check in with you. You look tired, perhaps you need a massage?" She offered happily, slithering into the room.

He started sweating, staring blankly ahead. "N-No, thank you though. I'm fin-" He managed, before going silent as the snake girl pressed into him from behind, her chest pressed tightly against his back.

"Trust me Darling, you really look like you need it." She cooed calmingly, having already begun rubbing her hands into his neck and shoulders. He nearly melted at her touch, going slack in his chair.

He wasn't a pervert, but he was sure that her rubbing her breasts against his back probably wasn't part of the massage… He bit his lip hard enough to draw blood, his fangs exposed. He could feel his wings and horns wanting out, but managed to hold back.

He glanced down at the form in front of him, spotting the top of the page where a couple warnings were listed.

(Signs that a Lamia is seducing you.)

(Page#1)

-Offering massages seemingly at random-

-Getting grabby-

-Wandering hands and intense direct contact-

-Pressing herself into you from behind-

-Breathing hotly onto your ears-

-The massage offered previously turns into something more sensual in nature-

-Ear biting-

Kimihito felt his blood run cold, the girl behind him having at some point begun lightly nibbling on his ears, her hot breath sending violent shivers down his spine. He hadn't noticed that at some point Miia's hands had strayed away from his neck and had moved to his chest, feeling and rubbing him through his shirt.

''Shit shit shit!'' He mentally ranted.

Miss Smith's warning replayed in his head, her menacing glare striking him cold. "You'd end up in jail too. So yeah, no sex. Not even foreplay." Smith stated as if it were obvious.

Kimihito suddenly stood up, surprising the Lamia. "I-I just remembered! I've got to do some s-shopping if you're going to live here!" He exclaimed, shuffling away from her grasp. He grabbed his wallet and shoes, before practically running out the door.

"My phone number is on the desk if you need me!" He vanished downstairs, grabbing his bike and blitzing down his street.

Miia watched her host hastily escape her lusting grasp, her lips upturned in a pout. She couldn't help but watch his cute butt run, and for the second time was confused by the sight of what looked like a tail wagging behind him, a tail from a species she swore looked familiar.

Was he a weeb that wore costumes at home? Darling sure didn't seem like the type. Unless, of course, he wasn't just a human.

But that shouldn't have been possible. From her whole life up to this point, she was taught that monster girls were female only.

She shook her head. Whatever the answer was, she was finding out the second he got back home.

"Hmph, I guess I tried too soon…" She pouted, crossing her arms. She slithered away, returning to her room. "Oh well, Darling will be back soon, I'm sure of it…" She muttered to herself, shrugging her shoulders.

"In the meantime, however…" She grinned, making her way through his house. "I wonder if he has a bath…"

A couple hours later Kimihito returned to his house, sneaking in as if he didn't even live there. His arms were full of bags of food, yes he did his research. He wasn't lying when he said he needed to go shopping for food.

He'd done some quick on the go research on what Lamia's need to eat to stay healthy, and had picked up the necessary things.

Of course, as he arrived back home, it was eerily quiet. He had honestly expected for Miia to jump out at him the second he entered the building.

He tiptoed inside, slipping his shoes off and sneaking into the kitchen. Miia wasn't here either. "Okay, okay… Maybe she calmed down…" He breathed, taking care to quickly put everything away. He was really hoping that she wasn't still horny…

With his head in the fridge, he didn't hear said snake girl sneaking up on him until it was too late. He would learn something here in a moment, and that was something he really should've thought about sooner.

"Hello Darling." Miia greeted happily from somewhere behind him. The half monster boy jumped, hitting his head on the fridge shelf. He tried to run, but stopped suddenly with a loud gasp, body completely and utterly frozen.

He shakily turned his head around, spotting with horror Miia, and worse, his tail clenched in the palm of her hand. He could feel his body stunned, completely at the woman's mercy. "H-H-Hey Miia?" He shakily got out.

The snake girl raise an eyebrow, eyeing him judgingly. "Darling… What's this?" She asked, shaking the silky black appendage around, not at all ignorant to the strained face he made. He bit his lips to stop from gasping out in pleasure.

"U-Uh…" His brain faltered, eyes twitching. "A costume piece?" He offered hopefully.

"A costume piece?"

"Yep!"

"That you wear casually?"

"Exactly!"

"So this isn't a part of your body?"

"Psh…" He coughed. "…no."

Miia narrowed her eyes, and Kimihito suddenly gained a horrible feeling. She tugged on it lightly, getting a quiet peep from her host. She raised the strangely twitching heart shaped tip to her lips, breathing hotly on it. It twitched, pulling away from her mouth.

Kimihito looked like a fish out of water, eyes wide and trembling. "N-Now… C-Can you just forget this ever happened and let go?" He asked hopefully. His hopes were dashed when a dangerous gleam entered her eyes.

"No." She didn't hesitate, taking the tip of the tail into her hot mouth, suckling on it, nibbling lightly with her dull fangs. She closed her eyes, running her twin tipped tongue over it, biting it.

"Guhwhah!" Kimihito hit the ground, a trembling mess. His face was twitching, face hot red, and breathing heavily. There was a poof and a tearing sound as her host's shirt was torn to pieces as a pair of bat like wings sprouted. Similarly two long horns grew from his head, his ears grew longer and pointed, and his eyes changed.

Miia slowly pulled the tip out of her mouth with a pop, sending a violent shiver down his spine. "I knew I felt something different about you Darling!" Miia cooed in joy, eyes sparkling.

Kimihito was muttering something unintelligible on the ground, face one of absolute embarrassment, and pleasure.

"So… does this make you a monster too? Ohh! This is so exciting! I never knew that monster boy's were real too! Mother said that was just a myth!"

…

"Darling?" She asked worriedly. Kimihito made a noise of recognition, but didn't seem capable of much more. His face was twitching in pleasure, mind running blank.

"O-Oh dear…" She whipped out her phone, quickly dialing Miss Smith's number.

"Miss Smith? Yeah it's-? No? No No No, mister Kimihito hasn't done anything to me. Yeah I uh… It was kinda my fault…"

"Huhwhah…." Kimihito muttered from his dazed position on the ground.

"E-Err… We'll it was actually my fault entirely. Yeah? You'll be here soon? Oh great! Darling, Miss Smith will be here real soon!"

"Mhnnnn." He groaned, hoping not for the first time today that he had decided to just stay in bed…
