****** Pleasured Possession ******
by SpadeQueenSumi
Summary
     After making a deal with Yoichi after a battle with Lacus, Gekkoin
     has full control over Yoichi's body just as long as he doesn't start
     any trouble.
Notes
     Happy birthday, Celeste! I hope you like this! It took me a while to
     finish, and there was no beta reader so please overlook the mistakes
     ;;
     *Also, while Gekkoin is in possession of Yoichi's body, I referred to
     him as Gekkoin instead of Yoichi, in case anyone was confused.
See the end of the work for more notes
Yoichi looked around the old room once again before his eyes landed on the
demon taking the form of his older sister. “Tomoe…” He'd accidentally left
leave his lips, even though he knew the person—the demon in front of him was
not her.
Even still, the demon looked over to him and smiled. “Hello again, Yoichi.”
Yoichi took a deep breath before sitting in the bed, extremely tired. “You
seemed worn out.”
“Gekkoin, why am I here? And why can't I seem to wake up?”
“You lost control.” Gekkoin said with a shrug. “I took over but one of your
teammates knocked me out.” Suddenly, Yoichi remembered snapbits of seeing
Lacus, his squadmates surrounding him with worried expressions, the feelings of
rage and sadness, shaking Gekkoin’s hand and then… nothing.
Yoichi nodded. “I see…” He looked up at Gekkoin. “So do I have control again?”
“As soon as you wake up, sure… but…”
“But?”
“ I have a proposition.”
===============================================================================
 
Yuu walked into what was left of the kitchen area. It had been a few hours
since they've stayed in an old house, what with them just narrowly escaping
that large battle that sparked when Yoichi attacked Lacus.
“Hasn't it… been too long?” Yuu asked, sitting at the almost deteriorated table
with the rest of the squad, excluding one brunet and one blond. He slid one of
the cans of beans over to Shihou.
“We can't really say for sure.” Shihou said, mixing the beans together before
eating some. “Remember when we first made our contracts with our demons? Yoichi
was the last to wake up.”
“Well, this is Yoichi we're talking about.” Mitsuba said. “He did learn to
manifest his demon the quickest. Not to mention he talks to his demon in his
sleep.”
“Yeah, and from what I understand Yoichi hasn't had much problems with his
demon like everyone else.” Narumi added. “Especially with everything that's
happened…”
Everyone was quiet for a moment.
“... Has it really been too long?” Mitsuba mumbled, playing with her fingers
Everyone looked over to Shinoa, seeing her slowly nod.
“It's only been a few hours, but even this is a bit worrisome.” Shinoa started.
“The only reason I could see Yoichi not waking up is if he had some problem
with his demon, but that is a bit… farfetched. Even in our academy days,
Yoichi's had amazing control over his demon and even Sayuri said he was
incredibly stable when handling demons. Nothing like this has ever happened
before with Yoichi, but I didn't think it would be too much of a problem
considering it seemed like Yoichi and his demon had a bit of an understanding,
but still, it's a bit worrying that he hasn't come back yet...”
Back in the battle when Yoichi had lost control of his demon and was possessed,
their only option was knocking Yoichi out before things got too out of hand.
They were only able to get away with the unexpected arrival of the Demon
Imperial Army. Once they were safe and sure that they weren't being followed,
they'd found an old house that wasn't completely ransacked of all its
resources, so they decided it would be best to rest there and wait for Yoichi
to wake up before decided what to do. The only problem was Yoichi wasn't waking
up.
“So, I guess we'll just have to wait it out then, huh?” Narumi said, taking the
can of beans from Shihou and eating a spoonful. They all sat in silence before
Mika walked into the room, the look on his face was a mixture of annoyed and
flustered. “What's wrong with you?”
“I think you guys need to see this.” Mika said before turning back where he
came from. “And you might want to hurry.”
“What? Did the vampires find us already?” Yuu said, standing up quickly and
giving everyone else a start.
“Or the army?” Mitsuba said, quickly standing with everyone else. Mika turned
back to them with a grimace, letting them know that neither was the case. “Then
what could be so bad that we all need to go to it quickly?”
“It's about Yoichi.” That got everyone following Mika to the living room
quickly. They all prepared themselves for the unknown. Maybe Yoichi had started
spitting up blood? Maybe he's gotten a fever? They weren’t sure, but they
weren’t taking any chances and prepared themselves for anything. They were,
however, still shocked to see Yoichi sitting up, sporting purple markings on
his face, catlike eyes and two horns sitting upon his head.
“Y-Yoichi?!”
He looked over at them, smiling widely and giving them a wave. “Yo, the name’s
Gekkoin.”
===============================================================================
 
“You want to give me a break?” Yoichi asked, bouncing on the bed a little bit
before looking at Gekkoin.
“Yeah.” Gekkoin said, leaning against the desk. “Let me take control of your
body and you rest here. I could even change the scenery if you want.”
“Gekkoin, you expect me to give you full control of my body until you feel like
giving it back.”
“Well, why wouldn't you?”
“Last time you had control, you tried to kill my friends.” Gekkoin tched.
“That was before. I'm doing better now. You of all people should know that.”
“Why do you want control? Aren't you having fun here?” Gekkoin frowned
prompting Yoichi to laugh. “I'm kidding.”
“And I hate it when you ‘kid’ with me.”
“Learn to have a sense of humor, Gekkoin.” Yoichi joked. “But I still don't
know why you want my body.” Silence. “Gekkoin?”
“Look, kid, like I said, I'm just trying to give you a break. You’re tired and
worn out and I can really tell that you need some rest.” Yoichi's eyes widened.
“Plus, like I said, I'm bored, so honestly, it's a win-win situation.”
Yoichi was quiet for a moment. “What would you do with my body?” Gekkoin
shrugged.
“I don't know? Look at the scenery, kill a few monsters? Who knows.”
“Fine.”
“Wait, really?”
“Yes, but under one condition.” Gekkoin rolled an eyebrow. “You aren't allowed
to kill any of my friends. If you so much as hurt anyone, there will be
consequences.” Gekkoin looked a bit shocked before chuckling and holding a hand
to Yoichi.
“Well, if it's just that, I guess we can make a deal.”
===============================================================================
 
It was the fifth night of Yoichi being possessed by his demon and there was
still no sign of Gekkoin giving Yoichi back control of his body. Luckily for
the squad, the demon seemed to have no need to cause havoc or murder
anyone—something about a promise to Yoichi—so they didn't have to worry much
about letting him loose.
Narumi sat down on the bed of the room he'd claimed after changing into clothes
that were almost his size, the pants legs were just a little short, but as long
as he didn't have to sleep in his uniform he was alright. He'd just gotten back
to his room after making sure everyone else was sleeping alright and
comfortably. He'd hate to say it out loud but he'd taken on some type of
responsibility for the squad, maybe a bit overprotective, but he felt he had
good reasons to be.   
‘Sure ,’ he thought, leaning back on the bed with his arms folded behind his
head. ‘ It's been five days but there was no reason to trust a demon that
possessed someone.’
He breathed out his nose before taking his hair down and running a hand through
it. He closed his eyes, wondering just how long it would be before the ‘tamed’
demon decided to stop playing around and strike.
He jolted when the door of the room creaked open, closing not long after so the
room was dark when Narumi sat up to see who'd walk in. He squinted when he felt
the bed dip not too far from him and prepared to summon his weapon when the
intruder suddenly moved to straddle his hips and whispered in a soft voice his
name.
“Narumi…” His eyes widened in the darkness.
“Y-Yoichi?” Narumi asked. He was a bit shocked. Had Yoichi returned back to
normal from the time he'd just seen him and now? He knew it could have happened
but them getting that lucky… Then again, would Yoichi honestly find Narumi in
the middle of them night and straddle him like he was? Narumi quickly reached
over lightly a match and candle, letting the light brighten the dark room
before looking at Yoichi, seeing he still had his horns, sharp teeth and
sinister smile, but his face markings were missing. “Demon…”
He laughed, placing a hand on Narumi's chest slowly, almost teasingly. “Aww,
were you expecting something different?” Narumi snarled, resisting the urge to
summon Genbushin and attacked the demon now, knowing it wouldn't do anything
but hurt Yoichi.
“Your marking disappeared.” Narumi said, avoiding Gekkoin's question. The demon
tilted his head, silently questioning why Narumi decided to bring it up. Narumi
smirked. “Does that mean you're losing control or something?” It was moreso a
demand than a question, Gekkoin almost seen it as a jab if he's being honest.
Despite the jab, Gekkoin laughed.
“Oh no, it's nothing like that. Yoichi's still very much asleep.” Gekkoin said,
the hand on Narumi’s chest running up to his shoulder, then down to his wrist,
bringing Narumi’s hand up to caress his face. Narumi blushed at the feel of
Yoichi's soft cheeks against his hand. “I did this for you, actually.”
“For me?”
“Yes, of course. You never looked at me face to face when I had the markings.
And how do you think Yoichi would feel if one of his favorite humans wouldn't
even look at his face.”
Narumi's eyes widened, “F-favorite...—?”
Gekkoin nodded. Narumi tried to push down the thought of how cute and Yoichi-
like he looked. Gekkoin's other hand moved up to caress the back of Narumi's
hand on his cheek, rubbing the skin before moving down to his wrist. “Yep,
favorite. You hurt even my feelings when you avert your eyes like that.”
Gekkoin leaned forward, pressing his lips against the shell of Narumi's ear.
“How cruel, Narumi.” he shivered as Gekkoin began pressing kisses on his neck,
his unoccupied hand running through his hair as he pressed his body weight
against him, making him lie down.
“A-ah…” Narumi sounded as Gekkoin's sharper than normal teeth started to tease
at his skin. His hands shot to Gekkoin's hips as he started to feel them
moving, rotating against his own. Narumi was almost ashamed to say he was
getting a bit turned on by the demon's advances, but what could he say? The
voice in his ear, the body on top of his, the tongue on his neck… they all
belonged to Yoichi. How was he supposed to push him away?
Narumi, against his better judgment, closed his eyes, leaning his head back and
rolling his hips up against Gekkoin's. Gekkoin pulled away from Narumi's neck,
kissing up his jaw before pulling away to look at him. Narumi's face was red
and slightly sweaty, but Gekkoin thought the way his eyebrows furrowed and he
bit his bottom lip was adorable, and he didn't hesitate to tell Narumi this.
Narumi glared up at him, but closed them soon after, letting out a moan as
Gekkoin's erection matched up with his. Gekkoin kissed down his chin, giving a
suck at the area just under his Adam's apple. “ Nah-ah … Yoichi.”
Gekkoin liked the way his master's name glades off Narumi's lips and wonders
briefly if he was used to moaning out Yoichi's name like that. Was it something
Yoichi wasn't telling him? Or did Yoichi not know either?
Gekkoin shook his head and decided to focus on the task at hand, making sure to
roll his hips slowly, loving how Narumi tried to desperately rolled his hips to
get friction against his erection. Narumi leaned his head back against the
pillows, allowing Gekkoin to lean forward and begin placing kisses on his neck
and leave occasional hickeys. Narumi tightened his hands against Gekkoin's
hips, listening as both their breaths began to quicken, both of them getting
closer to release. Narumi looked up, looking at Gekkoin and studying him
through his aroused haze.
He did certainly look like Yoichi. Especially since the markings were gone, and
his eyes were closed as he moved his hips back and forth. Only the horns were
an indication that Yoichi's demon had taken over him, but everything was so
Yoichi-like that it through Narumi for a loop. His eyes shut tightly, his small
pink lips fell apart, his thighs quivering against Narumi’s hips, his cheeks
were beginning to flush a pretty red as he continued to build him and Narumi up
to their orgasm.  
For a moment, Narumi could pretend that it was actually Yoichi on top and that
thought alone was what brought him over the edge far quicker than he usually
did. With a muffled moan and a quick whisper of Yoichi's name, Narumi came
inside his pants like a prepubescent boy, a wet spot growing on his crotch,
making Gekkoin shiver before coming himself.
They both stayed still, catching their breath before Gekkoin finally looked
over to Narumi, his catlike eyes filled with mischief and a smirk adorning his
face. Narumi’s eyes widened, slowly coming into terms with what happened,
before blushing in embarrassment as he suddenly felt the wetness in his
pants—although, he was slightly happy to know he's not the only one, but with
the boastful look on Gekkoin's face, he hardly counted the fact a victory.
Once Gekkoin had left, Narumi laid in bed (after changing, of course),
wondering just what the hell had happened.
===============================================================================
 
“So, you're trying to tell us that Yoichi's demon just up and seduced you?”
Mitsuba said, crossing her arms as she leaned back against the couch. Narumi
nodded. “Why would he do that?”
“I don't know.” Narumi said. Looking around at the squad’s faces of disbelief.
“You have to believe me though, it  happened. ” Shihou, Yuu and Mika stayed
quiet off to the side, but Shinoa and Mitsuba looked at each other before
looking back to Narumi.
“Are you sure you didn't just… dream it?” Shinoa sampled and Narumi groaned to
the sky before finally unbuttoning the top of his uniform coat, holding down
the collar to show the array of hickeys Gekkoin had given him the night before.
“Alright, so you weren't making it up.”
“Why would I lie?”
“So what are we supposed to do now?” Yuu asked, looking at everyone before
looking at the squad leader. Shinoa shrugged.
“Well, it's not as if we know what he wants, and we also can't  do  anything
without possibly hurting Yoichi… but it also isn't like he's doing anything to
hurt us perse…”
“So we just gonna stand by and let him do what he wants?” Shihou questioned.
“We aren't just going to stand by.” Shinoa said, putting her thinking face on.
“We just need to keep an eye out on him, see what his next move is.”
“So, our plan is to watch him.” Mika asked, looking over blankly as Shinoa
nodded.
“It'll be just like with Yuu-san. We'll take turns and see what information we
can gather, alright?” Everyone agreed, and they made a schedule of who would
watch Gekkoin and moved away from the group, going back to their regular
activities like everything was perfectly normal.
===============================================================================
 
“Are you my babysitter today?” Gekkoin asked as Yuu walked into his room,
holding his uniform jacket. Gekkoin huffed in boredom, knowing the squad had
gone on a mission, leaving one behind to watch him. Yuu smiled at him. “I've
been here for about a week now, when will you humans understand I've no reason
to fight you?”
“We're all just wondering when you'll decide to bring Yoichi back.” Yuu
sampled, crossing his legs despite sitting in a chair, his jacket sitting on
the back of it. Gekkoin rolled his eyes.
“I'll bring him back when I feel like it.” Yuu rolled his eyes but nonetheless
said nothing. They sat in silence for a moment before Gekkoin rolled over to
look at Yuu. “Aren't you supposed to stand guard outside? What do you want from
me?”
“I was gonna ask you to bring Yoichi back, but for whatever reason you seem
really sure on keeping him.”
“It's because I really like having this body—”
“I think you and I both know that's not true.” Gekkoin frowned. “Ya’ know,
Yoichi talks very well of you. He really thinks of you as a friend.”
“Of course I know that. I know a lot of things regarding Yoichi.”  
“Oh?”
“Yeah. I know he's very fond of you.”
“I'm fond of him also.” Gekkoin looked shocked, but his shocked look was soon
replaced with a smug one. Yuu's face hadn't changed except the small blush that
was growing on his cheeks.
“Oh? So does that mean I have a chance?” Yuu opened his mouth but closed it
again before he blushed. He'd figured he wouldn't lie to the demon, hoping to
establish some kind of truce so he'd bring back Yoichi, but he wasn't expecting
his kind of outcome. “What? Cat got your tongue now?” Gekkoin sat up then,
moving so his legs hung off the bed, sitting right between Yuu and the bed.
Yuu closed his eyes and took a deep breath before opening his eyes. “Bring
Yoichi back.”
“Don't wanna.” Gekkoin said, reaching forward to play with Yuu's collar,
fingers traveling to Yuu's neck, lightly caressing his Adam's apple before
going down as far as Yuu's shirt would allow before Yuu shivered and his hand
shot up to grab Gekkoin's.
“Stop that.” Gekkoin's smirked at Yuu's flustered face.
“Why? Your neck sensitive or something?” Yuu gulped, shaking his head as he
pushed Gekkoin's hand away. “Aren't you fond of me?” He toyed.
“I'm fond of Yoichi, not you.”
“But I am Yoichi.” Gekkoin smirked and shuffled closer to Yuu, his knees
hitting Yuu's before he moved. Gekkoin pouted at Yuu's reluctance but put both
his hands on Yuu's thighs, leaning forward to whisper. “There's no need to keep
resisting, I can make it worth it.”
“What do you mean by that?” Gekkoin looked Yuu in the face and smirked.
“I'm sure we both know what I mean.” His hands on Yuu's thighs moved up. Yuu
let out a heavy breath when Gekkoin kissed his neck, his shoulders relaxing as
he leaned back against the chair. Yuu flinched a little when Gekkoin bit his
neck, but shivered in pleasure, much to Gekkoin's amusement. Gekkoin cupped
Yuu's slowly rising hard on, before giving it a soft squeeze, making Yuu suck
in a hard breath, hands holding tightly at the chair like he was trying to
restrain himself. Gekkoin smiled sinisterly at the action for giving Yuu
another squeeze, slightly firmer this time. “Come on, Yuu. Where's the fun in
that?” Yuu took another breath as Gekkoin continued to tease him.
It had only taken one more bite on the neck for Yuu to finally react. Just as
Gekkoin pulled away from his neck, little drops of blood leaving the holes
Gekkoin's teeth created, Yuu grabbed the demon by his hair, pulling him away
from his neck and into a hasty kiss filled with nothing but lust and desire.
“Keep moving your hands.” Yuu ordered before leaning over and biting Gekkoin's
neck repeatedly, living bite marks in his wake. Gekkoin pushed down the growl
that crawled up his throat at being told what to do.
Nonetheless, he began to move his hands, rubbing against the growing bulge,
cupping his hands around the size. Gekkoin doesn't even try to hold back
moaning at Yuu's size and makes it known that he's very satisfied with how it
feels in his hand. After a moment of this, Gekkoin unzips Yuu's pants, pulling
his dick out and jerking it teasingly, making Yuu hiss. Gekkoin began kissing
down Yuu's body, moving out of his lap and onto the floor as his kisses got
lower and lower until…
“Haah…” Yuu moaned as Gekkoin grabs his dick with one hand and kisses the tip,
sticking his tongue out just a bit to lick the slit, tasting the salty precum
that started to slowly bead out. Gekkoin peaked up as he took Yuu's dick into
his mouth, feeling triumphant when Yuu leaned his head back, letting out a
shaky moan and thrusting his hips a little. Gekkoin opens his mouth wider,
hoping to get more of Yuu into his mouth, but Yoichi's mouth isn't trained for
this. He could feel his jaws beginning to ache at the stretch and his eyes
begin to water despite not having all of Yuu in his mouth yet.
“Oi, don't try to take it all at once like that.” Yuu scolds, suddenly reaching
up to grab onto Gekkoin's hair, grabbing the locks and tugging him back gently.
Gekkoin tries not to shiver as Yuu's fingers brush against his horns, but the
sensation is nicer than he thought it would be and he can't help that it makes
him feel a lot of pleasure. Gekkoin groans against the skin of Yuu's dick and
Yuu shudders and groan in response. “Hey… what's that about?” Yuu demands,
eyeing Gekkoin's as he runs his hands through his brown hair before his thumbs
hook on the base of the demon's horns and he moans loudly.
Yuu eyes widened as Gekkoin looked up at him with a lewd expression. Yuu has to
stop himself from smirking as Gekkoin tries to blink the obvious arousal he
feels and just when Gekkoin thinks he has his expression under control and
moves to put Yuu back into his mouth, Yuu strokes his horns slowly, and he
let's out a moan, body shaking as the sensitive feeling danced up his spine.
Gekkoin laid his head against Yuu's knee, trying to collect himself, but Yuu
continued to stroke his horns, twisting his wrist every which way and watching
as Gekkoin became undone just by this. “Hm, who would have thought you'd have
such a cute side.” Yuu mumbled, one hand going into Gekkoin's hair, pulling
back so he could see his turned on expression. Yuu studied Gekkoin's red,
sweaty cheeks, his dazy, dewy eyes and his tongue poking out his lips. “How
lewd,  Yoichi .” Gekkoin shivered, but didn’t get a word out as Yuu guided his
mouth towards his dick, making Gekkoin take a mouth full of him.
Gekkoin started sucking Yuu's dick, rubbing his tongue up and down the skin
whenever he could, trying not to be too distracted by Yuu playing with his
horns, which proved to be quite difficult since Yuu only put his hands on his
horns. Yuu stroked Gekkoin's horns at the same pace Gekkoin blew him.
Yuu knew he was close to coming, especially since he couldn't keep himself
quiet, moaning with each twist of Gekkoin's tongue. Yuu peeked down at Gekkoin,
watching as his brown hair swayed slightly with each bob of his head, letting
out pleasured noises as he squirmed in his place between Yuu's thighs; Yuu
would have completely forgotten that Yoichi had been possessed had he not had
his hands wrapped around the demons horns, guiding him through the blow job.
Yuu didn't want to admit it, but the thought of ‘if it was really Yoichi’
crosses his mind right before he felt his release coming.
“Hmm! Ah!” Yuu moaned as he grabbed Gekkoin's hair, pulling him closer before
coming inside his mouth, excess slipping through the sides of his mouth. Once
Yuu's grip in his hair went slack, Gekkoin pulled back, trying to swallow all
of Yuu’s cum, all of what wasn't swallowed dripped down his lips along with his
saliva as he panted. Yuu leans back against his chair, arms going limp against
his sides as he tried to catch his breath. Yuu looked down at Gekkoin, noticing
his eyes were shut as he laid against Yuu's knee. “Hey, don't you need to—”
“No, don't touch that—” Yuu’s eyes widened when he touched the crotch of
Gekkoin's bottoms, noticing the wet spot. Gekkoin shuddered and moan, hips
moving to shy away from Yuu's touches. Yuu smirked, quickly fixing up his pants
for bringing Gekkoin forward, cradling him in his arms as he kissed and nipped
at his neck some more.
“Let's get you cleaned up, yes?” Gekkoin groaned in response.
===============================================================================
 
Gekkoin grimaced as he spooned more beans and ate it. It had been a while since
he's been in a living, breathing body, but he was at least smart enough to know
that in order to last in one, he'd need some type of nutrients and if it had to
come from an old can of beans, he guess that'd have to work. He started to
wonder how Yoichi could live like this.
“So, was your intention just to come here and have sex with all of Yoichi's
teammates?” Gekkoin looked up in surprise, seeing Shinoa sitting on the table
in front of him and he cursed. He prided himself on his awareness to the world
around him, how could he have let a child slip into his personal space without
him knowing?
“What makes you say that?”
She shrugged. “Well, you've already managed to seduce Narumi and Yuu-san, and I
seen you eyeing up Kimizuki just a few hours ago…”
Gekkoin smirked. “Damn, and here I thought I was being discreet about it. What
are you going to do now that you know.”
Shinoa shrugged, picking up a butter knife off the table and playing with it.
“Just wanted to know how long until you give Yoichi his body back.” Gekkoin
sighed, the smirk falling from his face.
“Well, you already know what my goal is. I'm not leaving until I get what I
want.”  
“What about me?” he had the nerve to look bashful.
“Well, I hadn't really thought about it  too  much, but if you want—”
“No.” He blew out some air.
“Fair enough. I take it the other one’s off limits as well.” she looked at him
questionably. “The blond girl.”
“Micchan? What makes you say that?” Gekkoin gave her a pointed look. “Yeah,
she's off limits too.”
“Is this because I got Yuu before you did.” she shrugged, but Gekkoin could see
the small blush against her cheeks. He laughed, “The least you could do is be
honest with me.”
“And the least you could do is give Yoichi his body back, but I can see you
aren't doing that.” Gekkoin shrugged at her sass, eating and grimacing another
spoonful of beans into his mouth.
===============================================================================
 
As it turns out, Shinoa didn't even have to warn Gekkoin to stay away from
Mitsuba, because the second he showed a sign of seduction towards her, she
summoned Tenjiryū and threatened to slice him in half, Yoichi be damned.
He wasn't sure if she was serious or not—especially since he'd noticed she's
been taking care of him for Yoichi's sake—but he decided not to take any
chances.
===============================================================================
 
Shihou was a lot easier to seduce than Gekkoin had thought. Well, Gekkoin
wouldn't say he  seduced  Shihou per se, but he did get him pliant enough to
have sex with him—er, he couldn't say that either. He'd come onto Shihou in the
middle of the night, and all the boy said was, “What? So it's my turn now?”,
before Gekkoin could even get a word out. He asked if he would bring Yoichi
back after he's had his fill of everyone and if he was just another person to
cross off the list. Gekkoin had said yes and Shihou just gave in.
From the start, Gekkoin was a bit confused, put off to say the least. That had
to he the reason he lost control, he reasoned with himself. That had to be the
reason why he was laying on his back in Shihou's adopted room, naked with
Shihou's slicked fingers playing at his entrance. Gekkoin shivered despite
himself as Shihou worked him open, lips mouthing the side of his throat as he
whispered dirty nothings into his ear.
Gekkoin threw his head back as Shihou started to suck and nibble on his chest.
“W-why is this  necessary …?” he moaned out. He cursed Yoichi for having such
sensitive skin.
“I take it this hand marks on your hips are from Narumi, right?” he asked,
leaning forward and sucking another hickey on his chest. “And the marks on your
neck are probably from Yuu.”
“Y-yeah? And?”
“You haven't healed them yet, so I wanna leave some.” Gekkoin groaned at his
foolish reasoning, but closed his eyes and let out another moan as Shihou left
more marks, adding another finger inside him and moving them around slowly.
With the time Shihou had put into prepping him, Gekkoin was shivering and
gripping the bed spread under him and Shihou just looks so  smug  that it
nearly pisses Gekkoin off—
“Nnnah! Shit—!” Shihou chuckled as he drags his fingers against Gekkoin's
walls, pushing against them and scissoring his fingers.
“That's not a very Yoichi word to use.” Gekkoin glares at him through his lust
filled eyes before reaching up and pushing against Shihou's shoulder weakly.
“E-enough with your teasing.” Gekkoin cursed himself for stuttering, for
sounding so wretched and desperate. “Lay down.” He ordered, letting out a small
moan as Shihou removed his fingers from him and obeyed his orders, although
doing so smugly. Gekkoin took a deep breath to calm himself, tries to get his
breathing in order as he moves to straddle Shihou, much like he did when he
first made his entrance, both knees pressed into the bed, on the sides of
Shihou's hips.
Gekkoin shivered heavily as he reached back and angled Shihou's penis to his
entrance and felt the head of Shihou's penis brush him before trying to slide
down on it; he cursed once more. Why was he so…  big.  He was only sixteen for
goodness sakes; why was he so well endowed. It wasn't fair to poor Yoichi,
whose body is a lot smaller than his and it wasn't fair to Gekkoin. Gekkoin
suspected his thoughts were readable on his face because Shihou looked a bit
smug—or maybe it was just in Gekkoin's imagination?
Shihou watched as Gekkoin struggled to stay quiet as he slide down his dick and
his hands move to Gekkoin's hips, slowing the pace at which he was descending
upon him. “Hey, if it's too much, slow down.” He said firmly.
“Don't patronize me, boy.” Gekkoin whispered, only for Shihou to roll his eyes.
“I'm not. You'll end up hurting Yoichi if you rush and don't get used to it.
Why do you think that I took so long prepping you?”
‘Because you're an ass?’  Gekkoin bites back the response, but takes it slower,
although it does nothing to keep Gekkoin from feeling so vulnerable. As much as
Gekkoin hated thinking about it, Shihou was big, so he pressed against his
walls and stretched his hole more than his fingers did. It hurt, yes, but with
the lube he'd found somewhere in the house and the delicious friction he felt
inside of him, it made his toes curl. Gekkoin let out a deep breath once his
hips connected with Shihou's, his arms shaking a bit from where they pressed
against Shihou's chest and his thighs clutched against Shihou's hips.
Shihou rubbed his hands up and down Gekkoin's thighs as the demon struggled to
catch his breath, only for Gekkoin to smack them away in irritation. Shihou bit
down a laugh, knowing it'd do nothing but further irritate him, and decided it
would be best for him to stay quiet until Gekkoin decided to move.
Once Gekkoin felt he'd adjusted enough to Shihou's size, he rolled his hips,
biting down a moan at the sensation and doing it again. Shihou took a deep
breath through his nose as he watched Gekkoin slowly rise his hips and just ask
slowly sitting down on Shihou's dick. He did this a few more times, rolling his
hips each time he was fully seated in Shihou, keeping his pace consistent,
throwing his head back as the head of Shihou's penis brushed against his
prostate. Gekkoin cursed mentally, feeling overwhelmed as he moved his hands to
Shihou's knees, attempting to speed up his pace, but deciding against it when
Shihou thrust his hips up, hitting his prostate dead on, causing him to moan
out.
“This is nice, but who do you plan on satisfying with this pace?” Gekkoin's
eyes snapped open before he glared at Shihou. Shihou smug expression continued
to piss him off as the boy sat up, wrapping his arms around Gekkoin and
planting a firm hand on his lower back and hip, pulling him chest to chest with
him. “Hold onto me.” Gekkoin begrudgingly did what he said, laying his chin
against Shihou's shoulder as he waited for whatever it was Shihou was trying to
do. Needless to say he was very shocked when Shihou trusted up into him and
grinded himself inside before rolling his hips, rubbing against his prostate.
“A-ah!” Gekkoin yelled, tightening his arms around Shihou's shoulders, burying
his face into his arms as he heard his master's voice cry out in pleasure. This
wasn't how things were supposed to happen. He was supposed to have  others
crying out in pleasure, make them moan Yoichi's name yet it was the other way
around?
Gekkoin mumbled out Shihou's name as he began to claw at his back, breathing
heavily against his neck to try not to moan too loudly, but wasn't coming up
successful. Shihou let out a small moan of his own, “Haah… you sound  just
like him…” before placing an open mouth kiss against his neck.
Shihou buried his hands into Gekkoin's hair, gripping his hair tightly as he
pulled him closer, raving over the pants and moans he was letting out with each
thrust. He noted how much Gekkoin was clenching around his dick and groaned,
feeling that he was close. He moved one hand from Gekkoin's lower back to his
penis, and the other from his hair to the back of his neck. Shihou heard
Gekkoin whimper as he stroked him along with the pace of his thrusts. Shihou
hissed in pain as Gekkoin gripped at his shoulders, digging his nails into the
skin.
“Kimi...zuki-kun…!” Shihou groaned, vaguely aware of how much just  that  undid
him. Shihou gasped when Gekkoin bit into his shoulder, his orgasm shaking him
to the bone and his semen coating Shihou's fingers. Shihou didn't last long
after, thrusting only two more times before coming as well.
They stayed as they were for a second before Shihou leaned back against the
bed, pulling Gekkoin down with him. They both regulated their breath before
either moved.
“You were supposed to lay back and let me do everything.” Gekkoin scolded,
sitting up against Shihou but making no move to pull out. Shihou raised his
eyebrows at this but didn't comment on it.
“I didn't feel like waiting on you.” Gekkoin glared at Shihou, briefly
remembering Yoichi telling him how patient and gently Shihou actually was
because of the influence of Yuu.
Gekkoin quickly called bullshit.
===============================================================================
 
“I may have… miscalculated my plans just a little bit.”
Yoichi looked up sleepily at the demon from his place on his bed. Gekkoin had
once again taken the form of his deceased sister. Yoichi yawned, rubbing his
eye as he began to sit up.
“Should I take over again?” Gekkoin frowned.
“I'm not through playing yet.” Yoichi hummed before laying back down on the bed
and looking at his demon. 
“So, why'd you decide to tell me this?” 
“I thought you'd want to stay updated, but I guess not.” Gekkoin said, making
his way over to Yoichi, taking the folded blanket at the end of the bed and
putting it over Yoichi, making sure he was cozy. Yoichi resisted the urge to
roll his eyes.
===============================================================================
 
Mika sat down in the old car, grimacing as he climbed in. The front seats were
pushed all the way and torn and the back seats were a mess with dust caked on
top. It'd have to do, however, it he wanted somewhere close enough to the house
to go in if something happened but far enough away that no one would disturb
him.
“You're up really late, aren't you, Mika?” Mika looked over to the passenger
seat where Gekkoin had entered, face once again clear of any markings (Narumi
warned them about that, he was trying to look more like Yoichi.) Mika frowned
before looking up at the missing roof as Gekkoin sat down. “Oh come on, there's
no need to ignore me!” He laughed. “You wouldn't ignore Yoichi.” Mika remained
silent and that prompted Gekkoin to pout. “You know, they say you should always
save the best for last and that's why I decided to come to you last, so there's
no need to be jealous—”
“When are you going to bring him back.” Mika said, suddenly turning to Gekkoin,
shocking him enough to stop him from talking. “Don't you think it's been too
long.”
Gekkoin sighed. “You know, I completely understand that Yoichi is the one you
want, but don't you think you're being a bit cruel to me?” Mika scoffed.
“I've been having to deal with you demons since I left Sanguinum, and just when
I thought the worst was over, you showed up.” Gekkoin rolled his eyes,
maneuvering so he could climb over to Mika's lap, who, surprisingly, didn't
move to stop him. He ignored the hard on he felt pressing against his belly as
Gekkoin scooted closer to him, pressing his chest against his.
“I thought we've already established that I'm not like the demon that you've
had to handle with Yuu. We're two different kinds of demons.”
“Right. Because you're  tamed .”
“No. Well, yes, but that's not what I meant. Oh well, it's not like I expected
you to understand.” Gekkoin shook his head like he was disappointed in Mika's
lack of knowledge, promoting him to growl. “Easy there, tiger, it's not like I
came here to rail you up. Well, not in that sense.” Mika rolled his eyes.
“Yes, of course, I know. You've gotten quite the reputation.” Gekkoin actually
looked proud. “But what makes you think I'll have sex with you?” It wasn't much
of a question and more so Mika teasing Gekkoin the same way he did.
“Well, you like Yoichi don't you? Ah, well, more than Kimizuki.”
“In all fairness, I like everyone more than Kimizuki.”
“But you'd still fuck him wouldn't you.” Mika blushed, both at the accusation
and the fact that the work ‘fuck’ had come out of Yoichi's mouth with Yoichi's
voice. The demon was really pulling out the stops of ‘acting like Yoichi’,
wasn't he?
“What's any of that got to do with this.”
“Nothing really, I just wanted to see you blush.” Mika glared at the smirk
Gekkoin sent him. “But this can all end here, Mika.”
“What do you mean?”
“Like I said, you're the last one. After this, I'll be gone, and you’ll all
have your precious Yoichi back, safe and sound.” Mika squinted at Gekkoin in
disbelief. “I swear to you.”
“And what makes you think I'll trust you?” Gekkoin shrugged.
“Whether you believe me or not has nothing to do with me telling the truth, but
it's all completely up to you. You could either have sex with me and I bring
Yoichi back, or you could be the reason you guys are stuck with me.”
“So basically it's a lose-lose situation for me.” Gekkoin chuckled, closing his
eyes before opening them, causing Mika to gasp sharpy. His iris were no longer
catlike, but instead as round as Yoichi's.
“You act as if it won't feel good for you,  Mika-kun. ” Mika growled and for
the first time since Gekkoin's taken control over Yoichi's body, he felt like
he was about to be attacked.
“Get in the back seat.” Mika snarled out, shaking Gekkoin out of his shock
before making him crawl over the seats into the back. Mika stepped out of the
car, moving to the back seat and Gekkoin suddenly began feeling like prey.
“Well?”
“Well what?”
“Strip yourself.” Gekkoin's eyes widened. There was no way this kid was
serious.
“Isn't that your job?” Mika raised an eyebrow, showing that he meant business
and Gekkoin scowled. He was already turned on, and Mika was making no move to
react to the fact, so it would seem Gekkoin had to play by Mika's rules if he
were to get what he wanted.
Gekkoin began the irritating process of taking off JIDA’s stupid uniform when
he realized Mika hadn't moved to take off any of his clothes. He started to
shake in irritation, feeling as if the vampire was somehow looking down on him,
but he pushed the feeling aside as he got his pants and underwear off, reaching
up to start unbuttoning the white, undershirt when Mika learned forward and
kissed him.
Through his irritation and shock, Gekkoin let him, releasing the buttons and
wrapping his arms around Mika's neck. Gekkoin leaned back slowly as Mika began
the onslaught against his lips, spreading his legs as he pushed Gekkoin on his
back. Mika rubbed the inside of Gekkoin's thighs before tracing his hole, only
to find it surprisingly wet and loose. “You prepped yourself?” Mika asked,
already pushing two fingers inside him, causing Gekkoin to choke on his words.
“I-I didn't want you teasing me… like K-Kimizuki did.” He stated as his head
lolled back, Mika's almost impatient pacing making him feel overwhelmed. He
felt like he was being built up too quickly. Mika hummed, but otherwise stayed
very silent as he continued to play with Gekkoin, pressing against his walls as
if he was stretching him. “I said I'd already—mmh…”
“I want to make sure you did a thorough job.” He replied smartly, adding a
third finger. “Wouldn't want Yoichi hurting when he comes back.” Gekkoin glared
at him through his lashes. What was up with these kids? It felt as if all of
them had found a way to sass or patronize him in some way. He was a powerful
demon, dammit. He deserved to be feared and respected. “Alright, that sound be
enough.” Mika mumbled, quickly slipping his fingers out, making Gekkoin groan
at the friction and the lost.
Gekkoin watched numbly as Mika took off his clothes, moving closer in between
Gekkoin's legs while lining his dick up to his hole. Mika took a deep breath.
“I'm not going to go slow, so just a heads up.”
“W-wait—” Gekkoin cut himself off with a gasp as Mika thrusted into him, only
giving him a moment to adjust before pulling back and thrusting into him again.
Gekkoin gripped at the tattered seats, trying to get some kind of grounding as
Mika continued to thrust into him, his pace increasing slowly. Gekkoin wasn't
sure if it was because of Mika's vampirism, but he couldn't help but feel as
though Mika was thrusting into him too fast, hitting all the right spots with
too much intensity. Once again, Gekkoin felt overwhelmed. Gekkoin wondered why
these boys seemed to know his master's body well enough to render him into a
useless pile of oversensitivity. Mika adjusted his footing in the car, placing
one foot on the floor before pulling Gekkoin closer and grinding into his
prostate. Gekkoin's hands shot to Mika's shoulders, practically arching his
hips away from Mika. “Nnah! M-Mika! Mika, wait—”
“Say it like  he  would.” Mika interrupted, leaning forward and licking up
Gekkoin's sweaty neck. Gekkoin bit his bottom lip hard enough to make it bleed,
but he didn't have to worry about it because Mika was quick to lap up the
trickles of blood, sucking his bottom lip into his mouth before pulling away
with a loud ‘pop’. Mika pecked Gekkoin on the lips quickly before speaking
again. “Say my name like Yoichi would.” Gekkoin nails dug into Mika's flesh as
Mika continued to roll his hips against his, probing his prostate as he did.
“M-Mika-kun! Mika-kun—AH!” Gekkoin was shocked that Mika had actually leaning
over and bit into his neck, arousal soon overcoming the shock, leaving him
jolting in Mika's grasp as the vampire continued to thrust into him as well as
take his blood—which shouldn't be as pleasurable as it was. Arousal ran through
his body so quickly that his mind blanked for a moment and all he saw was pure
white. Gekkoin came quickly afterwards. This was the second time he'd come
untouched, but he couldn't dwell on it for too long. Not when Mika was still
thrusting in him in such a way, leaving him speechless.
Mika stopped thrusting, pulling away from Gekkoin's neck and giving it a lick,
getting up any remaining blood he’d missed. “Hold on to me, I'm not finished
yet.” Gekkoin gasped, wrapping his arms around Mika's neck before he continued.
He continued to use Gekkoin's oversensitive body, making him yell out until all
his moans quieted to a whimper and his body was numb with pleasure. Mika came
with a loud moan against the mark he'd put on Gekkoin's neck, taking a few
minutes before pulling away and looking at Gekkoin.
Mika smirked as the demon could hardly keep his eyes opened, probably blissed
out from being used after coming like that. “So, you'll bring Yoichi hack like
you said?” Mika asked, caressing the side of his sweaty face. Gekkoin nodded,
fluttering his eyes to try to stay awake as he leaned into Mika's soft touch.
“Good.”
===============================================================================
 
“Y-Yoichi!” Everyone yelled, running to the boy when he somewhat limped into
the kitchen the next day, eyes normal, hornless with no face markings. Yoichi,
although clearly disorientated, looked at everyone before smiling.
“Hey, everyone. I'm back.” he laughed to everyone as they surrounded him,
telling them how much they missed him. “I'm glad to be back everyone, although…
I do have a question…” everyone quieted, watching as unbuttoned his uniform
shirt. “Why are there so many marks and bruises on my body?”
Needless to say, Narumi, Shihou, Yuu and Mika cursed Gekkoin simultaneously.
End Notes
     I ended with MikaYoi car sex because that's what I had planned before
     this huehuehue
     (Also, I've implied multiple tikes that this wasn't Yoichi's first
     time having sex with his teammates because, as Celeste put it, Yoichi
     has always been a hoe)
