Summary
     Mika was here, his family. Even if he was consumed by his demon side,
     he was still Mika and Yuu was going to be here to help him– even if
     he had to be stuck here for an eternity and leave the human world
     behind. He would do anything for his family.

When Yuu opened his eyes again it was to find the same dreamscape he’d been
having for the past few weeks. It’d all began when Mika turned into a full
demon and became his. For some reason, he couldn't contact Asuramaru anymore–
Yuu figured that Mika must have forcibly pushed him away when he became Yuu’s
new demon.
However, unlike Asuramaru, Mika didn't want him to leave.
There was no escape, just an endless scenery of white skies and imaginary
backgrounds, forever running through a vast space. And honestly, Yuu didn’t
want to leave even if he had the option to.
Mika was here, his family. Even if he was consumed by his demon side, he was
still Mika and Yuu was going to be here to help him– even if he had to be stuck
here for an eternity and leave the human world behind. He would do anything for
his family.
Soon, Yuu felt arms circling around his waist, pulling him against a familiar
body of a tall, blond male. “Yuu-chan…Yuu-chan…you're awake.” His low voice
whispered against Yuu’s ear, pleased and yearning. Mika pressed him impossibly
close to his chest like he was trying to combine their bodies together.
“Mika, how have you been doing?” Yuu asked softly, turning his head sideways
and bringing a hand back to caress Mika’s cheek. He didn’t resist as Mika only
nuzzled the crook of his neck and tightened his hold on him, mumbling his name
over and over again like a prayer against his skin.
Mika didn’t look much different from when he was a vampire— he still had blood
red eyes and fangs as sharp as knives behind his full, pink lips. The only new
addition were the pair of black horns sticking out of his blond curls,
signifying his changed nature. But despite all that, Yuu only ever saw Mika,
his Mika.
For some reason though, when Mika changed into a demon, he seemed to have
reverted to his twelve year old personality— all clingy and affectionate. He
wouldn’t stop touching Yuu every chance he got and surprisingly, Yuu didn’t
find it as bothersome as he normally would. Part of the reason was that he was
jut as clingy to Mika as well. There was a constant need inside him to check
out for Mika, to make sure he was still there, still alive. So he'd touch back,
hug back, kiss back even, and it wasn't at all strange or awkward for Yuu.
It would be different if Asuramaru were to suddenly be this clingy towards him
since Yuu knew the smaller demon only wanted to possess him. But with Mika,
there were no trickeries or lies. Even though he was a demon now, Yuu still
trusted him with his entire being. Mika would never intentionally hurt him.
“Yuu-chan, it was so lonely without you. So lonely….never leave me again.
Please.” Mika pleaded, the same plead he’d ask of him ever since he got here.
It ached something inside Yuu whenever he’d hear Mika’s weak tone so Yuu always
tried his best to reassure him, make him know that he was loved and that Yuu
would never leave him behind again. That was a mistake he never should have
made four years ago.
“I promise, Mika. I'm here, I'll always be with you, don't worry.” Yuu answered
back, turning around in Mika’s hold to press their foreheads’ together. He
raised his other hand to cup Mika’s cheek, breathing in the familiar scent that
Mika emitted when they were this close. Yuu didn't know how to describe it but
it felt just like home. (He tried not to wonder how his subconsciousness was
making him use all five senses like he was actually in the real world. But Yuu
wasn't complaining. He was glad he could feel Mika like this, and it made him
forget that this was all in his head.)
With a smile, Yuu opened his eyes to find red ones already staring back at him,
watching him with an intense singularity that only Mika could achieve. Then
before Yuu knew it, the blond had leaned in and gave Yuu a small peck, leaning
back a bit after as if Yuu might not like it. However, he didn't give Yuu much
time to get over his surprise before Mika was leaning in again, connecting
their lips far longer, sliding and caressing plush lips with a fervent need.
Yuu kissed back without thinking any longer, swept by the feeling of Mika in
his arms, of Mika’s lips against his, his tongue persistently delving inside
Yuu’s open mouth.
“I want you. I need to have you again.” Mika pleaded when he pulled back,
tugging Yuu’s uniform collar aside to lick on the exposed skin there. His
tongue burned a path up the curve of Yuu’s neck, sucking on the soft skin which
elicited a gasp from the human before he teased the area with a fanged tooth.
This was another habit that Mika developed as a demon, his need for constant
blood but with an added factor to it…
Yuu tilted his head back to give Mika further access, lacing his hands through
his hair as Mika dotted innocent bites around his neck before finally sinking
his fangs on a single spot. Yuu was so used to it now that he only shuddered as
the sting came and went before the rush of pleasure flooded through him. He
could hear Mika moaning beside his ear, his hands moving from Yuu’s waist to
cup the back of his head and the other traveling down to his ass. Yuu had to
stop himself from jerking forward when Mika groped him there, trying not to
accidentally dislodge the fangs inside him. But it was difficult to think when
his pants were ripped away and Mika was now touching him directly, palms slowly
kneading the flesh of his rear.
He barely even felt Mika sucking his blood, too distracted by the hand pushing
his lower area flush against Mika’s front, until the demon pulled back, licking
his red lips greedily. With eyes half-lidded, Yuu followed that tongue as it
swiped the blood away from those tempting lips before hiding back inside.
Seeming to have noticed Yuu’s lustful gaze, Mika hurriedly meshed their lips
together again, flicking his tongue against the roof of Yuu’s mouth which
earned him a moan.
“Mika, hurry. I want you too. So much.” Yuu whispered urgently between kisses.
They were so eager for more, tongues slid out to touch first before lips could
even close around each other. Tightening his grip on the back of Mika’s head,
Yuu kissed him harder feeling like his lips were about to break from the
continuous rough onslaught but he just wanted more– and from the way, Mika was
enthusiastically sucking his bottom lip, he wanted it too.
Fumbling one-handed on the buttons of his coat, Yuu was too focused on their
heated kiss to notice that Mika had changed the scenery around them, pushing
Yuu back until he was trapped against a wall. Moaning, Yuu tightened his grip
on Mika’s hair, arching up against him when their hips pressed tantalizingly
together. Even as a demon, Mika still wore his white vampire uniform (except
for the cape) that Yuu slightly hated because they were a layer too many to
reach to Mika’s body. The demon could have as easily vanished their clothes
with a simple thought but then, it seemed Mika liked being able to rip fabric
away from Yuu’s body when he could. And Yuu honestly had no complaints there.
Sue him, but Yuu loved it when Mika showed just how badly he needed him.
He snapped himself back to the present when Mika scraped a fang against his
collarbone this time, sucking on the jutted bone hungrily, forcing a moan out
of Yuu’s throat. “Mika…” Yuu whimpered, fighting through a wave of pleasure
that assaulted him as he bucked and rubbed his hips against the other’s thigh.
A growl reverberated from Mika’s throat as he watched Yuu’s skin flush a pretty
red, green eyes growing half-massed and dark with need. He dug his fingers
under the curve of Yuu’s ass and the raven haired man yelped when he was
suddenly lifted in the air, legs instinctively wrapping around Mika’s slim
waist.
“Need you...so much— Yuu-chan…” The way Mika said his name sent shivers down
Yuu’s back. It was so full of desire and need and love— Yuu felt an ache
building inside him. He wanted to give Mika everything he needed and if that
meant offering his body, so be it. Mika was his only priority right now.
“Then don’t hold back, Mika. Take me.” The blond demon didn’t need further
encouragement as he turned them around and threw Yuu on the bed that popped up
beside them. Yuu awaited the blond with open arms as Mika bent low and licked
the curve of his neck, laving it with his saliva before fangs sank into the
tempting flesh again. Yuu enjoyed the warm pleasure that followed after the
initial pain, oozing from the spot where he was bitten and flowing throughout
his body. It made him turn pliant and lax under the demon.
While straddling his thighs, Mika drank from him and traveled his hands in the
lovely space between Yuu’s legs. The human twitched but didn’t move any
further, anticipating the touch of those cold hands on him as they crossed the
valley of his cock and balls and moved to his most secret place.
Apparently, Mika preferred sucking Yuu’s blood while he was fucking him. Yuu
had been shocked the first time when Mika tore through his clothes and gave him
a handjob while feeding from him but Yuu quickly learned to adapt to it. To be
honest, it felt good for Yuu too and he didn’t object too much because having
Mika inside him, connecting their bodies in the most intimate ways felt like
paradise in Yuu's mind.
Yuu gasped, lolling his head on the sheets as he felt a finger prod gently
against his entrance, circling slowly around it. The slight pressure made Yuu
shiver and it kept on rubbing against his puckered hole again and again until
Yuu was close to begging Mika to just stick it inside him already. With his
other hand, Mika slid it under Yuu's white shirt to roll his thumb around a
small, pink nipple, tweaking it playfully. Stifling a pleased purr, Yuu arched
his back when the fingers teased him mercilessly, pinching his nips until they
were hard peaks while fingers pushed against his opening.
Craning his head to the side when Mika bit harder on his neck, Yuu cried out as
at the same time, Mika’s fingers finally plunged deep inside his tight passage,
wiggling against his walls and stretching his muscles loose.
Wrapping his arms around Mika’s neck, Yuu moaned against his ear and spread his
legs wider, trying to relax to allow more fingers in him. They moved in and out
in a leisurely pace, curling and scissoring inside him until they hit a spot
inside Yuu that had him gasping and throwing his head back in pleasure.
Mika pulled back from his neck and licked his ruby red lips, watching Yuu’s
reactions as he slowly pulled his fingers out. The human groaned and shook
under him, opening his eyes to give Mika a pleading look. “Come on, Mika…
please. I-I want you.”
"Yuu-chan..." The demon couldn’t resist as he positioned himself over him and
began pushing his cock against the pink, wet hole, leaning down over to cover
Yuu’s lips with his. Swallowing down his cute gasping sounds, Mika inched his
way further and further until he was sheathed completely inside Yuu’s tight
channel, groaning in delight when soft muscles clenched tight all around him.
“Yuu-chan, I’m all the way...in.” Mika gasped, mouthing against Yuu’s lips.
Though the other could only mumble broken words of “yes” and “more” to Mika
while he arched at the amazing feeling of having Mika finally inside him.
He started his pace slow, moving hips back and forth while he held Yuu’s hips
steady, mouth frantically moulding with Yuu’s. Their tongues peeked out and
licked at each other, tangling sensually and letting drops of saliva sliding
down the corner of their mouths.
“Mika...it’s okay.” Yuu threaded his hands through soft blond locks, tugging
Mika closer to him as he felt his shaft moving a bit faster inside, “I won't
break.”
His gentle words seemed to push the demon into action. Mika pushed the back of
Yuu's shapely thighs against his torso, his ass hanging in the air and the
demon grunted as he pounded his way into him. Yuu threw his head back and cried
out, trying to move his hips back as Mika quickened his thrusts.
“Ahh! Mmm...y-yes, Mika, more…”
Cupping the blond's face, Yuu leaned up to press a kiss on his lips, letting
himself be taken by this beautiful creature over and over again. And when the
tip of his dick hit something deep within Yuu, he shrieked and involuntarily
clenched down harder on Mika’s length. Scalding hot pleasure burned up Yuu’s
spine, sending him spasming on the bed and eyes rolling back as Mika slammed
into him again and again.
“Mika! Mika!” He moaned out loud. His arms weakly tried to bring them around
Mika’s neck, tears prickling in the corner of his eyes as he was rocked
frantically on the sheets. “Yes! Y-Yes—!” But then Mika suddenly pulled out and
Yuu whined at the emptiness inside him for half a second, before the demon
flipped him over and buried himself deep inside his raised ass again.
Yuu’s screams were muffled against the pillows, broken by Mika’s frantic
thrusts, as thighs slapped against ass and their moans echoed in the empty
room. The bed creaked with sounds of their coupling, hitting against the wall.
Though it wasn’t like they had anyone to annoy in their lovemaking because Yuu
could barely stop screaming—everything felt so good.
“Fuck, Yuu-chan, you feel so tight, so hot,” Mika moaned, hands slipping around
Yuu’s waist as his pace became more and more manic. He thrusts up, forcing out
another broken scream from Yuu.
“A-ahhh—! M-Mika… Mika...” Yuu’s voice sounded like nothing but sobs now,
barely audible compared to Mika’s heavy breaths and panting. “I... Please... I-
I need... I need to...”
He closed his eyes and urgently bucked his hips along to Mika’s thrusts, his
voice crescendoing into dirty, lewd moans. All he cared about was the heat
enveloping his entire body, the screaming in his brain telling him he needed to
cum, he needed to feel Mika cumming inside him, he needed it badly.
“Make... Make me cum!” he begged, meaning every word, every sound that escaped
pass his lips. “Please, Mika! I-I need you! a-ah!”
Then Mika wrapped a hand around his dick, gripping it slightly too tight and
stroking him at the same time as his thrusts. “Louder, Yuu-chan.” The demon
demanded. “Scream it louder.”
Yuu didn't need to be told twice. He arched his back and nodded, his mouth
falling open to scream brokenly, “P-PLEASE FUCK ME—! MIKA—AH—I-I WANT MORE--!”
Yuu’s voice cracked in two, but it didn't deter him from screaming. Behind him,
Mika swore under his breath, now pounding into Yuu’s prostate again and again
as if it were the only thing he could do. He moved in an animalistic pace, his
thrusts so fast that it was almost painful—but Yuu didn't want him to stop. He
couldn't stop.
“F-FUCK! RIGHT THERE, MIKA— AHH!– RIGHT T-THERE!” Yuu begged desperately,
trying to push his hips back as far as it would go to feel Mika deeper inside
him, wanting to feel him there even after they were finished. His voice was
hoarse and broken by the time Mika groaned and bit into his shoulder, ripping
out a pained cry of pleasure from Yuu. Burning pain spread throughout his body,
followed by wet kisses that sent his mind melting like a puddle as Mika
continued to stroke his dick at the same time.
“YES! Y-YES! MIKA—M-MIKA! IT F-FEELS SO GOOD—! YES, H-HARDER! P-PLEASE!”
Mika thrusts three more times, all hitting straight into Yuu’s prostate so hard
that Yuu was seeing stars and his screams turned into babbles, choking on his
own moans.
And just as Mika sucked hungrily from his shoulder, there was a burst like
fireworks exploding in the back of his eyes and Yuu screamed, clenching down
hard on the cock thrusting into him as his orgasm was ripped from his body.
“YES! YES! I-I’M G-GOING TO—A-AAH—!”
Yuu came into Mika’s hand, screaming out his name and convulsing against the
bed. He could only hold on desperately to the sheets as Mika fucked him through
his climax, heightening the experience even more as every pound against his
prostate spurted more cum out of his sensitive cock. The heat almost broke him,
blanking his mind for a short moment and rendering him useless.
After his high, he was twitching against the sheets as his orgasm washed over
him, too tired, too drained to do anything else but lie there and breathe. He's
vaguely aware of Mika crying out his name, slamming into him one last time
before he was cumming inside. There was pain that followed, his sensitive walls
stretched and swollen from Mika’s rough handling, no longer able to take much
more but the warming sensations spilling inside him strangely soothed it all.
The excess cum trickled down his thighs, but Yuu couldn't bring himself to
clean it up. He released a shuddering breath and found Mika’s arms circling
around his waist, pulling him close to his naked chest. Yuu didn’t know when
Mika had scraped all their clothes during the intercourse but Yuu was too tired
to think. He just rolled on his side and purred at the smatter of kisses Mika
rained down on his head and face, muttering sweet nothings in his ear. He
whispered back to Mika how much he loved him, winding his own arms around the
blond demon as well.
In this little moment with just the two of them together, Yuu could imagine
that they were still in the real world, resting in each other’s arms and
waiting for the next day to arrive. Yuu sighed tiredly, snuggling closer
towards his demon's chest as exhaustion soon fell over him. He wished that
morning would never come.
Though at the back of his mind, he knew there wasn’t going to be another
morning in their little world anymore.
