     desperately wants to help.
Notes

When he first met Tsukishima, looking down his nose at the bullies with a
sneered, “Pathetic,” he was too overcome with awe and gratitude to register
anything off about him. All he knew was that the tall boy seemed so brave and
cool, and that he desperately wanted to be like that too. But after a few weeks
of tailing the blonde boy, determined to become his friend though sheer
persistence, Yamaguchi couldn’t help but notice things.

First, Tsukishima didn’t want to be touched. That he established early on, when
Yamaguchi accidentally brushed up against him while they were walking to school
together in the early morning. Tsukishima had flinched violently, hissing his
displeasure at the brief contact.

“Don’t ever touch me,” he had said, with deadly seriousness in his tone.
Yamaguchi’s eyes had widened, and his already customary “Sorry Tsukki” was
barely audible in his shock. He made sure to walk with space between them after
that, tending to hang just behind because the boy’s longer legs already made it
difficult to keep up.

The second oddity took Yamaguchi longer to notice, as he just passed it off as
some genetic quirk in Tsukishima’s mixed heritage. But the more he spent time
with Tsukishima at school, around other students, the more he saw the contrast
in their skin tones, how deathly pale Tsukishima seemed, especially under the
school’s harsh lights. He had thought to himself that Tsukishima needed to get
out in the sun more, and that was when he realized the third strange thing. He
had never seen the other boy in direct sunlight.

His relentless determination to spend as much time with his new friend as
possible had caused him to start tailing the boy home after school. Tsukishima
never left the building before the sun began going down, not that Yamaguchi
noticed at first. They would spend the time after the end of classes in the
library, where Tsukishima would block out the world with his headphones as they
worked on homework. The first time he followed Tsukishima home, it was mostly
out of curiosity, but once he realized they lived nearby each other, they
started walking together every evening. This led to morning walks as well, and
while Yamaguchi had to wake up much earlier than he would otherwise, he didn’t
mind.

Beside the early start and the late departure, he realized that even during
their breaks between classes, Tsukishima either stayed inside, or under the
shade of trees or buildings. Often he would read or listen to music, ignoring
the other students and usually Yamaguchi too. Still, Yamaguchi stuck by his
side. He felt so much safer with Tsukishima, and because he spent all his time
with the taller boy, he was no longer bullied or picked on (aside from when
Tsukishima himself threw scathing comments his way).

When Tsukishima joined the volleyball team, muttering angrily that his parents
thought he needed exercise, Yamaguchi didn’t hesitate to sign up as well.
Tsukishima quickly exhibited a particular interest in blocking. Initially, the
team was so short that they could only practice blocking while standing on
boxes, but Tsukishima seemed to take pleasure in shutting down his teammates’
hitting attempts. Yamaguchi didn’t seem to have talent for anything specific,
but he was determined to contribute to the team like Tsukishima.

It wasn’t until the end of junior high that a new strange thing about
Tsukishima began to emerge. Yamaguchi started to notice dark bags appearing
under Tsukishima’s eyes, a stark contrast to his pale skin. He had gotten
crabbier than usual too, snapping at Yamaguchi to shut up whenever the freckled
boy opened his mouth to ask him if he had gotten enough sleep, or if he wanted
some extra food from his lunch. The latter question seemed to make him
particularly edgy, but Yamaguchi couldn’t help but ask. They had both gone
through growth spurts, but Tsukishima had gotten especially tall, and looked
thinner than ever because of it. But despite Yamaguchi’s best efforts, his
friend would accept none of his extra food.
 
 
 
It was during exam period that Yamaguchi asked if he could come over to
Tsukishima’s house to study with him, as they had several classes together. He
didn’t expect Tsukishima to agree, as any attempts to visit had been shut down
in the past. But this time, after a moment, Tsukishima sighed tiredly and
nodded his head.

“My parents aren’t home tonight, so sure. Why not.” His voice was flat, but
Yamaguchi barely noticed because excitement swelled inside him.

“Awesome!” he exclaimed, and Tsukishima rolled his eyes as he began to put his
books in his bag. The sun was setting, so naturally it was time to head home.
Yamaguchi was nearly skipping behind his friend as they made their way toward
Tsukishima’s house. He had seen it before, but generally he met Tsukishima a
couple blocks away. He looked up at it now and thought to himself that it
seemed normal enough, though the curtains were drawn in every window.

They entered after Tsukishima unlocked the door, and Yamaguchi stared around in
fascination. This time, Tsukishima’s disparaging look was warranted, as the
inside was about as normal as the outside. But to Yamaguchi, this was Tsukki’s
house, and that meant it was special.

They made their way to Tsukishima’s room, which was sparely furnished and neat.
A wide smile stretched across Yamaguchi’s face when he saw dinosaur figures
displayed prominently on Tsukishima’s shelves.

“Tsukki, I didn’t know you liked dinosaurs! Which one is your favorite?”

“Shut up, Yamaguchi,” Tsukishima said tiredly, sitting at the low table in the
center of the room and pulling out his books.

“Sorry, Tsukki,” Yamaguchi replied, feeling a little disappointment at his
failure to engage Tsukishima in a topic he clearly cared about. He sat across
from the blonde boy, and pulled out his books as well. After a few minutes of
silent studying, however, Yamaguchi couldn’t hold in his worry anymore.

“Tsukki, please tell me what’s wrong…you’ve been so tired lately, and you
haven’t been eating, and I’m worried about you! Can I help at all?”
Tsukishima’s eyes flicked up in annoyance.

“I’m fine. There’s nothing you can do to help.” He looked back down at his
books pointedly, but Yamaguchi wasn’t giving up this time.

“Please Tsukki! I’ll do anything! Just tell me, so I can help you!”

Tsukishima paused, and a moment passed before he looked up, fixing Yamaguchi
was an intense gaze. He seemed to be considering something, and Yamaguchi held
still, his face earnest and hopeful. Then Tsukishima seemed to make a decision
and he moved, more quickly than Yamaguchi could process, suddenly appearing
right in front of him.

“Anything?” Tsukishima asked quietly, eyes not leaving Yamaguchi’s. Unease
tugged at Yamaguchi’s stomach, but his dedication to his friend was much
stronger and he nodded firmly.

“Fine.” Tsukishima said. “If you want to help…you can’t tell anyone about what
I’m about to do, okay? If you do, I can’t be responsible for what happens to
you.”

“I won’t tell anyone.” Yamaguchi promised quickly. “You can trust me.”
Tsukishima nodded slowly, and something that seemed like vulnerability crept
into his eyes.

“Then…don’t move.”

Tsukishima reached out slowly with one hand, and Yamaguchi had to summon all
his willpower not to flinch because Tsukishima had never touched him before.
This wasn’t okay, was it? But he stayed still. Tsukishima had told him not to
move, so he wouldn’t.

Tsukishima’s fingers brushed against Yamaguchi’s cheek and Yamaguchi inhaled
sharply. Tsukishima was cold, deathly so, and Yamaguchi’s worry about his
friend increased dramatically. What was wrong with him? He desperately wanted
to help, to do whatever he could, so he still didn’t move, didn’t shy away from
the icy touch. Tsukishima was obviously doing something he was unsure about,
revealing something special to Yamaguchi, and he wanted Tsukishima to feel
comfortable with him, to trust him.

Tsukishima moved closer, until his knees were almost touching Yamaguchi’s. Then
he leaned in and suddenly, Yamaguchi felt cold lips on his own. His eyes
widened in surprise, but when Tsukishima pulled back a little, he couldn’t help
but smile. He never dreamed something like this would happen. He had never been
kissed before, but he knew in that moment that he liked it, because it was
Tsukishima.

There was still vulnerability in Tsukishima’s eyes, but his mouth quirked into
a slight smirk at Yamaguchi’s apparent happiness.

“You okay?” he said softly, and Yamaguchi nodded quickly. So Tsukishima leaned
in again, kissing Yamaguchi more firmly this time. The coldness of his friend’s
lips was strange, Yamaguchi couldn’t help but think, but the lips themselves
were thin and soft. He closed his eyes this time, leaning into the kiss. They
stayed like that for a moment before Tsukishima’s mouth began to move slowly
against Yamaguchi’s and he did his best to follow the blonde boy’s lead. It was
unhurried and intimate, and Yamaguchi relished every second of it.

When they finally broke apart, Yamaguchi couldn’t help but sigh, in happiness
and disappointment at the loss of contact. He blinked a few time, focusing on
Tsukishima’s face with a dreamy smile. His smile faltered, however, he was
noticed they was still nervousness in the other boy’s face.

“Is this okay?” he asked worriedly, and Tsukishima raised his eyebrows in
surprise, before snorting.

“I should be asking you that, right?” he said, glancing at the floor, then back
at Yamaguchi. Then he sighed. “There’s something else I want to do with you.
It’s going to hurt, okay? But I promise it’ll help me, more than you know.”

Yamaguchi stared at him, then shook his head vehemently. “I don’t care, I’ll do
it. I want to help you.”

Tsukishima smiled, which caught Yamaguchi off-guard. His friend never smiled,
not as wide as he was doing now. And as close as they were, Yamaguchi couldn’t
help but notice how long Tsukishima’s canine teeth seemed to be. He began to
open his mouth to say something, but Tsukishima was already moving, with a
sense of determination. Then his mouth was on Yamaguchi’s neck, who gasped at
the sudden cold contact with his skin. Tsukishima sucked at the spot, pulling
blood toward the surface of the skin, then before Yamaguchi could respond with
more than a small noise of pleasure, he opened his mouth wider and bit hard.

Tsukishima’s teeth sunk deep into Yamaguchi’s neck, and a cry of pain tore from
Yamaguchi’s mouth before he could stop it. His head fell back, exposing his
neck even more, and though his eyes stared at the ceiling, he didn’t see it.
His brain was clouded over by pain and he felt tears begin to form at the
corners of his eyes. Then Tsukishima began to suck, hard and with a deep
thirst. Yamaguchi slumped, but Tsukishima’s arms were there, wrapping around
him, drawing him close to Tsukishima’s body so he couldn’t fall. Yamaguchi
could feel the blood behind pulled from his veins as Tsukishima drank and
suddenly it didn’t hurt as sharply as it had before. Blood rose in him quickly,
flushing his face as it was drawn from his body and his hand went out to clutch
Tsukishima shirt in an attempt to ground himself, to keep his brain from
slipping away completely.

His ears, which had seemed blocked up, began registering the wet sounds of
Tsukishima drinking from his neck, and another noise. A keen of pleasure and
relief was coming from Tsukishima, who was grasping at Yamaguchi’s body with a
frantic sense of urgency. Yamaguchi did his best to relax into him, with what
little lucidity he still possessed. In that moment, he felt almost peaceful,
the pulling sensation in his neck almost pleasurable.

Then the moment passed, and Yamaguchi began feeling distinctly light-headed.
Tsukishima was drinking too fast, and Yamaguchi could barely manage to beat
weakly against Tsukishima’s chest a few times before he felt himself losing
consciousness. He felt like he was falling, away from Tsukishima, away from the
world, and he could only manage a low whimper before the blackness overtook
him.
 
 
When Yamaguchi came to, he couldn’t tell where he was at first. The light of
the room was harsh and hurt his eyes, but when he tried to shield himself with
his hand, he found he couldn’t move. His breathing was shallow and weak, his
head was spinning, and there was a sharp pain in his neck. This pain, distinct
and throbbing, triggered something in his memory, and suddenly he remembered
what had caused him to pass out. At the same time, Tsukishima came into view,
looking down at him and blocking out the light, for which Yamaguchi breathed a
light sigh of relief.

With some effort, he focused on Tsukishima’s face. He thought he saw concern in
it for an instant, before the features settled into the gaze of indifference he
was familiar with. But the expression seemed somehow tighter than usual, and
Yamaguchi felt the need to ask what was wrong, if he could help.

“What..?” he croaked weakly, but Tsukishima silenced him quickly with a cold
finger on his lips.

“I’m sorry,” he whispered, his tone at odds with his emotionless face. Then he
reached outside of Yamaguchi’s field of vision and the freckled boy felt
something press against his lips. He opened them on instinct and then there was
some kind of cookie in his mouth. He managed to bite down, and chew the piece
slowly before swallowing. Tsukishima pressed the cookie to his lips again, and
Yamaguchi took another bite and the process repeated until the whole thing was
gone. By then, Yamaguchi’s head had stopped spinning and he felt some strength
returning to his limbs.

“Will you…help me sit up?” he asked shyly, embarrassed by his own weakness.
Tsukishima responded instantly, however, slipping an arm underneath him and
lifting him up until he could lean against the dresser beside them.

“What happened?” Yamaguchi asked slowly, looking up at Tsukishima who was now
kneeling next to him. With surprise, Yamaguchi realized that Tsukishima looked
healthier than he had in months. His looked less gaunt, and while his skin was
no less pale, his eyes shone with energy.

Tsukishima swallowed before answering, glancing at Yamaguchi’s neck, which the
freckled boy realized was still throbbing painfully.

“I’m…a vampire,” he confessed reluctantly, and while Yamaguchi should have been
surprised, he only felt a sense of deep relief. Everything made so much more
sense now, he realized. The pale, cold skin, the aversion to light, and most
prominently, the whole blood-sucking thing. He nodded, wincing slightly at the
pain that shot to his neck.
Tsukishima grimaced in response before continuing.

“I was born this way, it runs in the family. I don’t know what you may have
heard about our kind, but don’t worry, my bite won’t turn you into one. Growing
up, I was able to survive on stored bags of blood, but when I hit puberty
recently, it wasn’t enough anymore. And you were there, saying you’d do
anything to help…I’m sorry, I got carried away. You tasted so good…”

He breathed the last part with a vehemence that surprised Yamaguchi.

“I’m sorry,” he repeated, looking down. “I could have killed you.”
 
Yamaguchi summoned his strength and reached out to touch Tsukishima’s cheek, no
longer fazed by the chill of his skin. Tsukishima flinched at the unexpected
contact, but his eyes met Yamaguchi’s and the freckled boy could see real
regret within them.

“It’s okay,” he said as earnestly as he could, and he really meant it. Despite
confusion and questions swirling in his head, Yamaguchi felt most strongly a
sense of happiness at being able to help his friend. Were they more than that
now? He didn’t know.

“I said I’d do anything, and I meant it. I want to do this for you.” Tsukishima
blinked in surprise.

“Really? Are you sure?” Yamaguchi nodded as best as he could.

“I mean, I’ll need some time to recover, and we probably should work out some
sort of system, but I want to be with you. To help.”

He smiled, and saw the lurking uncertainty begin to leave Tsukishima’s eyes.
Then a thought made him pause.
“Wait, if all you needed was my blood, why did you kiss me?” he asked,
confused. Tsukishima blinked, then looked away, mumbling something under his
breath. When asked to repeat himself, he sighed, then said, “I heard that it
makes it taste better...I’ve never fed from a human before, so I guess I still
don’t know for sure, but you tasted a lot better than the bags I usually
drink.” He shrugged.

“Well, I don’t mind,” Yamaguchi said earnestly. “I-I…liked it.” Tsukishima just
looked at him, so he kept talking hurriedly. “Would you have just kept using
the bags, if I wasn’t here?”

Tsukishima nodded, a look of distaste crossing his features. “They’re not very
good, but they do the job, I guess. Right now, since I’m growing and stuff,
they don’t really provide enough nutrients. It wouldn’t kill me or anything,
but you saw how I’ve been. Tired all the time, sick-looking…my parents were
talking about finding me some human to use, but this’ll be a lot easier.”

Yamaguchi listened with interest. “Okay, one last question.” Tsukishima rolled
his eyes, but didn’t say anything, so Yamaguchi continued. “Do you still eat
real food? I mean, I guess I’ve seen you do it, but…how does that work exactly?
Why did you have a cookie all ready to go?”

“We still eat, but our bodies crave things only blood can provide. It’s more
supplementary, I suppose, but it affects us badly if we can’t get it. As for
the cookie, well, my dad is human. My parents have been together a long time,
so they know how to handle things like blood loss. It was likely I would be
born like my father, but not guaranteed. My brother’s human, but I wasn’t so
lucky.” He said the last part with a grimace.

Yamaguchi frowned, then said with an intensity that surprised Tsukishima,
“Well, I’m here now, so things’ll get a lot better. Okay?”

Tsukishima couldn’t help but make a face and look away, though he nodded. That
was enough to satisfy Yamaguchi.
 
 
After they finished talking, Tsukishima told Yamaguchi to call his parents and
tell them he was spending the night, because he couldn’t possibly go home in
his current state. Despite severe blood loss, Yamaguchi still managed a light
blush, but Tsukishima quickly added that his condition also meant that they
wouldn’t be anything more, the tone of his voice implying that he knew exactly
where Yamaguchi’s mind had gone.

Yamaguchi’s parents signed off on the sleepover without too much trouble, and
Tsukishima set about making sure that the smaller boy ate at least two more
cookies before he would let him stand. When Yamaguchi finally was allowed up,
he quickly escaped to the bathroom, while Tsukishima went to the kitchen to
make more food. He immediately went to the mirror, and a sharp hiss of breath
escaped when he saw the deep bite mark. The red was vibrant against his skin,
but he noticed with interest that it already seemed to be healing. Attributing
that to Tsukishima and his special teeth, Yamaguchi went to the bathroom, then
made his way to the kitchen. Tsukishima was making rice, chicken, and broccoli,
and a glass of orange juice was waiting on the table. As he sat down at the
table, Tsukishima spoke without turning.

“Drink the whole thing, and I’ll pour you another one. You’ve lost a lot of
blood, and that’ll help.”

Yamaguchi made a noise of acquiescence and began sipping on the juice, watching
Tsukishima’s back. The blonde boy moved quickly, with more energy than
Yamaguchi had seen in him since…ever, probably. He couldn’t help feeling a
little pleased at how Tsukishima was fussing over him.

When he had finished the glass, and a second, the food was done, and Tsukishima
gave him a huge serving with a look that dared him to argue. Yamaguchi did his
best, but there was still a considerable amount left in his bowl when he pushed
it away. Tsukishima glared at him, but he just shook his head.

“I’m so full, Tsukki, I really can’t eat another bite. Besides, I’m feeling
much better!”

Tsukishima stuck out his hand, not believing a word of it.

“Squeeze,” he commanded. Yamaguchi did as he said, taking his cold hand and
squeezing with all his strength. Tsukishima made a face, but evidently his grip
was satisfactory, because the tall boy took Yamaguchi’s bowl and covered it
with plastic, putting it in the fridge.

“I expect you to finish it by the end of tonight, but I guess you can take a
break for now,” he said gruffly, sitting. Yamaguchi nodded happily, and
Tsukishima leaned into peer at his neck.

“It seems to be healing well,” he commented. “Next time…” and he paused,
prompting Yamaguchi to nod again, encouragingly. “Next time, it shouldn’t hurt
as bad, now that the initial bite is there.”

Yamaguchi breathed a little sigh of relief. He was prepared to endure the pain
again, as he had promised, but he was glad to know it wouldn’t hurt so severely
every time.

“How often do you think you’ll need to…?” Yamaguchi trailed off, uncertainly.
Tsukishima shrugged a little.

“Well, I don’t know for sure. This is pretty new for me too. Probably once a
day for a little while, until the cravings get less intense. I’ve never had
blood this rich before. But after my body calms down, we can either do small
sessions every other day or so, or one big one once a week.”

Yamaguchi nodded slowly, considering.

“This is the last week of school, so in the break before high school starts we
can probably do the every other day thing. But once classes kick in, once a
week would probably be best.”

Tsukishima shot him a look tinged with what Yamaguchi thought was concern.

“Are you sure you can handle it?” Yamaguchi nodded confidently.

“You said you went a little overboard this time, right? As long as we take it a
little slower, and I made sure to eat a lot beforehand, I’ll be fine!”

Tsukishima just made a noise of grudging agreement before looking at the bite
mark again.

“The collars on Karasuno’s uniform shirts should cover that up, but you should
still probably wear a bandage over it,” he remarked blandly, and Yamaguchi
blushed. He’d heard some of the other boys in his class gossiping about a
hickey they’d seen on a girl’s neck, and he couldn’t imagine what they’d say if
they saw the bite.

He was thankful that they’d be attending the same high school. They could have
made it work even if that hadn’t been the case, he supposed, but this would be
a lot easier. He leaned back, closing his eyes and rubbing his full belly with
a satisfied hum.

Tsukishima’s eyes softened a little, when he knew Yamaguchi couldn’t see. He
felt a deep sense of gratitude toward the boy, for his selflessness and
devotion. It was a feeling he knew he wouldn’t be able to express, but mentally
promised that he would take care of Yamaguchi, as best he could.
 
 
The next day, the two took the test that they had completely neglected to study
for, somehow scraping by despite being woefully unprepared. Tsukishima made
sure that Yamaguchi ate a big lunch before taking him into an empty classroom
and drinking from him again. He was right that it hurt less, but Yamaguchi
still had to cling to Tsukishima tightly to get through the initial pain of
Tsukishima’s fangs reopening the bite. Once he started to suck, however,
Yamaguchi again felt a strange pleasure that left him moaning to the ceiling.
When the light-headed feeling began to creep in, he thumped his fist against
Tsukishima’s chest until he released his neck with a gasp. Yamaguchi leaned
into the taller boy for support and they both breathed heavily.

“Damn,” Tsukishima whispered, before licking the bite mark roughly, causing
Yamaguchi to inhale sharply. “You taste so good.”

Yamaguchi smiled into Tsukishima’s shoulder, his chest buzzing with happiness.
 
 
They continued this way until exams were over and they were released from
junior high forever. As break went on, Tsukishima’s cravings got less intense,
as he had predicted, and they began limiting feeding to every other day.
Yamaguchi was almost sorry. It was necessary, so his body could recover, but he
had started to really enjoy the intimacy of the sessions. Tsukishima was not
particularly inclined to be affectionate toward him otherwise, and especially
not in public. He knew it was just the boy’s nature, but it made him treasure
the intensity and passion that flowed from Tsukishima when he drank from
Yamaguchi’s neck.

When high school began, Tsukishima begrudgingly agreed to join the volleyball
team again, as his parents still insisted he needed exercise and volleyball was
one of the few sports he could play entirely indoors. They were informed
immediately that they’d be playing a practice match against the other new
freshman, and Yamaguchi was quietly surprised by how the pair, Kageyama and
Hinata, were able to get under Tsukishima’s skin. After his growth spurt,
Tsukishima’s skill at blocking had increased dramatically, which he
demonstrated immediately against Hinata’s raw hits. He kept his face bored and
nonchalant, but Yamaguchi could tell how irritated their passion for volleyball
made him.

They ended up losing, and as they made their way home in the dark of the
evening, Yamaguchi felt his heart racing. Tsukishima walked ahead of him,
silently stewing, and while Yamaguchi wanted to reach out to him and provide
some kind of comfort, Tsukishima’s no-touching rule was still firmly in place
after they had gotten together. If Tsukishima hadn’t initiated anything,
Yamaguchi was to keep his hands to himself. So Yamaguchi was quiet and
respectful, and gave him his space.
 
 
As practice went on, things settled down a bit. Tsukishima was still disgusted
by the intense team spirt that seemed to ooze from everyone on the team, but he
seemed to accept that this was his life now and he couldn’t do anything about
it but tease Kageyama and Hinata relentlessly, when given the slightest
opportunity.

It didn’t help his irritability that the start of high school and volleyball
practice meant that he was only getting to feed on the weekends. Yamaguchi
secretly looked forward to each session though, because all of Tsukishima’s
annoyance and hunger got channeled into aggressive focus on his partner and, to
Yamaguchi’s excitement, lust.

Tsukishima had discovered, soon after the feedings became fewer that Yamaguchi
also had pent up feelings that were released during those weekends. The
freckled boy was starving too, but for affection, and when Tsukishima gave it
to him, his blood flowed faster and ran sweeter. He always made sure Yamaguchi
ate a big meal before they began, but after that was out of the way, he would
pounce, slamming Yamaguchi against a wall or pinning him to the floor, and
kissing him breathless.

When he did, he could see the delicious flush of blood rising into Yamaguchi’s
cheeks, which only served to fuel his actions. He began to learn what parts of
the boy’s body was the most sensitive, finding that kissing and sucking lightly
around the bite mark got Yamaguchi particularly excited, moaning into his ear
in anticipation.

The mark had been reopened so many times, that Yamaguchi could tell it would
never go away, a thought that strangely delighted him. Though they’d never
acknowledged it explicitly, he could tell that their relationship had deepened
beyond friends or food supply. He knew he belonged to Tsukishima, a fact that
the blonde boy would make apparent whenever he felt Yamaguchi was acting too
close to someone else. Yamaguchi suspected that was part of the reason
Tsukishima was so mean to Hinata, as he and the redhead had become good friends
over the last few months.
 

It was after a particular Friday practice where Yamaguchi had spent what
Tsukishima considered an unnecessary amount of time with Hinata that things
were laid bare.

Yamaguchi came home with Tsukishima like he did every weekend, something both
sets of parents were used to by now. Tsukishima’s parents spent very little
time at home, it seemed, so the boys were free to do whatever they wanted on
the weekends. When they arrived, and the door was locked behind them,
Tsukishima immediately shoved Yamaguchi against the wall, roughly pinning his
hands above his head and kissing him so hard Yamaguchi thought his lip might be
bruised. He cried out at the show of aggression, then whimpered when Tsukishima
bit at his lower lip, being less than careful with his sharp teeth. Tsukishima
ground his hips into Yamaguchi’s, gripping his wrists painfully, and finally
Yamaguchi had to cry out.
“Tsukki, stop! Please!”

The blonde boy froze, eyes unfocused and staring down at the floor. He slowly
released Yamaguchi’s wrists and his arms dropped to his side. His body shook
with heavy breathing.

Yamaguchi had never seen him undone in such a manner before and wasn’t quite
sure what to do. He tentatively reach out and pulled Tsukishima toward him,
wrapping him in a tender embrace that his accepted with a surprising lack of
resistance. Yamaguchi hugged him close, reaching up to pet the back of his neck
gently, and felt Tsukishima’s hands knot in his jacket. He was shaking.

“What’s wrong?” Yamaguchi murmured into Tsukishima’s ear, continuing to pet him
soothingly. “Please, talk to me.”

Tsukishima took an unsteady breath, then leaned his forehead into Yamaguchi’s
shoulder.

“I’m sorry,” he said quietly, in a way Yamaguchi hadn’t heard since he had
almost killed him during that first feeding. “I was…jealous.”

Tsukishima spat the word out like it disgusted him. But after he said it, he
seemed to shrink a little in Yamaguchi’s arms, withdrawing into himself as much
as his tall frame would allow. Yamaguchi pulled back, forcing Tsukishima to
look into his eyes.

“Tsukki,” he said firmly, “you need to understand that I have other friends
now. No, listen.” Tsukishima had flinched and looked away. “I’m happy on this
team, and I really like my teammates. Don’t you want me to be happy?”
Tsukishima muttered something under his breath and Yamaguchi grabbed his chin,
forcing eye contact with more confidence than he felt.

“I want you to be happy with me,” Tsukishima ground out, nostrils flaring in
distaste at the words coming out of his mouth.

Yamaguchi couldn’t suppress a little chuckle then, causing Tsukishima to
stiffen in his arms.

“I am happy with you, Tsukishima. I’m yours, you know that. It’s your mark
that’s on my neck. I can have other friends and still be yours. I don’t want
any of them like I want you. You’re special.”

Tsukishima’s jaw tightened as he looked down into Yamaguchi’s earnest face.
Yamaguchi went up on his tiptoes and kissed the tall boy’s tight lips until
they softened, allowing themselves to be drawn into a deep, intimate kiss. When
they finally broke apart, Tsukishima didn’t look quite so angry, and Yamaguchi
smiled.

“I know you’re cranky and hungry, so let’s go upstairs, okay? I’ll grab some
food and juice and meet you up there.”
Tsukishima looked like he wanted to argue, but his hunger won out, and he
reluctantly let Yamaguchi pull away from him and disappear into the kitchen.
The freckled boy quickly snagged an energy bar from the cabinet where he knew
they were kept and wolfed it down, followed by a glass of orange juice. Wiping
his mouth, he made his way upstairs to find Tsukishima lying on the bed, eyes
closed, listening to music. Yamaguchi crossed the room and climbed up beside
him, swinging a leg over Tsukishima’s hips. The tall boy’s vulnerability had
made him more confident.

Tsukishima’s eyes blinked open as Yamaguchi gently removed his headphones,
looking up at him with a strange expression that Yamaguchi couldn’t quite read.
He looked uncertain, Yamaguchi thought to himself, something he rarely saw in
Tsukishima’s face.

“Let me show you how much I want only you,” Yamaguchi murmured, leaning in
close and meeting Tsukishima’s lips with his own. Tsukishima’s hands went up to
grip Yamaguchi’s hips as the freckled boy deepened the kiss, coaxing
Tsukishima’s mouth open. He reveled in the wetness of it, the taste of
Tsukishima that he knew must be nothing compared to how deeply the other boy
had tasted him. He broke the kiss and moved to Tsukishima’s neck, eliciting a
quiet inhale of surprise. Yamaguchi had never taken charge in this way before.
He kissed and sucked at the cold skin, and when he pulled away he noted with
interested that no blood had risen to the surface.

He glanced at Tsukishima, who stared back from behind his glasses with an
expression of desire that sent chills through Yamaguchi. He made a decision
then, and began to move down Tsukishima’s body, hands dipping under his shirt,
pushing it up so he could begin to kiss the hard stomach underneath. He felt
Tsukishima shudder underneath him and he paused for a moment, right above the
tall boy’s waistband.

“Is this okay?” he asked quietly, looking up. Tsukishima swallowed, and nodded.
They had never gone this far before. To be honest, Yamaguchi wasn’t quite sure
what he was going to find when he pulled down Tsukishima’s shorts, but thought
excited him.

He slipped his fingers under the elastic of the waistband and began to work it
down, over Tsukishima’s sharp hips. He nudged Tsukishima’s sides and the boy
lifted his hips slightly so Yamaguchi could pull the shorts and boxers all the
way down. He paused then, to take in what was underneath.

He was pleased to see that Tsukishima’s dick looked relatively normal, albeit
just as pale as the rest of his body. It was proportional to his tall stature
too, he noted, impressed. What surprised him, was that Tsukishima’s dick was
rock hard, straining against his stomach. Yamaguchi reached out and stroked it
once, eliciting a low moan from Tsukishima, and realized that it was even
colder than rest of him, and that seemed to be what was making it so hard. He
reasoned to himself that since vampirism ran in families, they had to be able
to reproduce somehow. Tsukishima could probably come like anyone else. This
didn’t help too much, because he’d never given a blowjob before, but he hoped
his experience with himself would be enough of a base to get started.

He tried not to think about it too much, and instead took the head in his
mouth. It was like sucking on a popsicle, he concluded. The flavor was strange,
but not unpleasant, and he began to swirl his tongue around the slit.
Tsukishima’s hands tangled themselves in his hair, and his breathing became
more and more labored. Yamaguchi popped off of the head and busied himself
licking up and down the long shaft, pausing to give attention to the head each
time he passed it. After he was satisfied everything was good and wet, he took
Tsukishima’s dick into his mouth as deep as he could manage, using his hands on
the parts he couldn’t reach. Tsukishima’s hips bucked up as his hands pressed
his head down, and Yamaguchi choked for a moment before Tsukishima released him
with a hissed apology. Yamaguchi resumed his movement, falling into a rhythm,
his head bobbing up and down.

Finally, as Tsukishima’s breathing began rising in pitch, the blonde boy pushed
Yamaguchi off, hands on both his shoulders. Yamaguchi looked up in confusion,
but when he met Tsukishima’s eyes, they were dark with lust.

“I want to fuck you,” he said flatly, and pushed Yamaguchi onto his back.
Yamaguchi was startled, but allowed himself to be manhandled as Tsukishima
quickly removed his shirt and shorts, pausing at his boxers before pulling
those off too. Yamaguchi felt vulnerable, naked under Tsukishima piercing gaze,
but he looked up at Tsukishima with a shy, trusting smile. Tsukishima’s eyes
raked all over his body, taking in every inch, and then his mouth dropped to
Yamaguchi’s bite mark. He kissed it tenderly as he ran his hands up and down
Yamaguchi’s sides. One hand grasped Yamaguchi’s dick, stroking it and eliciting
a high whine from its owner.

Then Yamaguchi sat up a little, stopping him. Before Tsukishima could say
anything, he reached beside the bed and rummaged in his backpack, pulling out a
small bottle of lube. He pushed it into Tsukishima’s hands, blushing furiously
in a way that made Tsukishima’s mouth water. Tsukishima took the bottle with
raised eyebrow, but poured some of the slick liquid onto his fingers, moving
them to Yamaguchi’s entrance.
Yamaguchi gasped as he felt the cold touch and he opened his legs to give
Tsukishima plenty of access.
Tsukishima’s finger pressed against his hole and his other hand rubbed
Yamaguchi’s side gently, urging him to relax. Yamaguchi closed his eyes with a
sigh as the finger entered him. It was a strange feeling, but not a wholly
unfamiliar one. He had fingered himself before, imagining this very moment,
dreaming of when they’d take things to the next level.

Tsukishima’s finger moved slowly, in and out, going deeper each time until it
was buried all the way inside him. After giving Yamaguchi a second to get used
to the feeling, Tsukishima pulled it out a bit so that he could start working a
second inside, doing his best to be gentle. He leaned down to resume kissing
Yamaguchi’s neck, feeling the muscles squeeze around his fingers. Once the
second finger was inside, he began scissoring them back and forth, stretching
Yamaguchi out. The noises slipping out of Yamaguchi’s mouth became a steady
stream of gasps and moans, and when Tsukishima was satisfied, a loud keen
erupted from Yamaguchi as a third finger entered him.

Tsukishima’s hand work diligently, stretching Yamaguchi open so that he would
hurt him as little as possible. Finally, Yamaguchi panted, “I’m ready! Please,
Tsukki!” and he removed his fingers with a low chuckle. Moving between
Yamaguchi’s legs, he squeeze more lube onto his dick before lining it up. He
bent forward over Yamaguchi, capturing the boy’s lips with his own as he
pressed the head of his dick against the wet hole. Yamaguchi gasped into his
mouth as he entered him, clutching at Tsukishima’s shoulders desperately,
spreading his legs wider. His breath was coming fast, and Tsukishima moved to
whisper soothingly into his ear as his dick pressed deeper inside him.

“Shhh, it’s okay….you’re doing so well Tadashi,” he murmured, and Yamaguchi
gasped at the use of his given name. Tsukishima moved his hips, working his
dick deeper inch by inch until he was buried all the way inside the smaller
boy. He paused to give Yamaguchi time to adjust. The boy had never felt
anything like it before. It was cold, but that felt nice because his whole body
was on fire. He felt so full, so completely claimed by Tsukishima and he loved
it.

He nodded into Tsukishima’s shoulder and felt him begin to move, thrusting
slowly at first, then building up speed until they were both panting into each
other’s necks. Tsukishima’s hand dropped down to stroke the smaller boy’s dick,
eliciting a sharp inhale. Yamaguchi could feel his orgasm rising quickly and he
began to babble Tsukishima’s name over and over.

“Tsukki Tsukki Tsukki, I’m so close, Tsukki!” he called out, his voice
squeaking, but he couldn’t find it in him to care. Then Tsukishima’s mouth was
over his bite mark and he was opening his mouth wide. Sharp teeth sank deep
into his neck and Yamaguchi screamed, muscles clamping tight around
Tsukishima’s dick inside him.

The pain lasted only an instant before Tsukishima sucked hard, and Yamaguchi
came with a cry of pleasure, grasping at the fabric of Tsukishima’s shirt.
Tsukishima groaned deep in his throat as Yamaguchi’s muscles pulsed around him
and came too, continuing to drink deeply from Yamaguchi’s neck. His thrusts
slowed and then stopped, and he held Yamaguchi tight to his body, swallowing
mouthful after mouthful of delicious blood. Yamaguchi’s legs and arms were
wrapped around him like a vice, face buried in his shoulder, riding the waves
of his orgasm and the continuing pleasure of Tsukishima draining him dry.

Finally, his breathing began to slow and his grip started to loosen. He felt
faint, and weakly hit at Tsukishima’s chest with his fist. Tsukishima took one
last long pull at his neck before swallowing and releasing him. He slid out of
him slow and gentle and collapsed beside him on the bed. Yamaguchi immediately
rolled over to snuggle into Tsukishima’s side, ignoring the cum on his stomach
and thankful that the sore bite was on the side of his neck not pressed into
Tsukishima’s skin. Tsukishima’s cold body was very welcome, as Yamaguchi’s skin
was hot all over. He could feel Tsukishima’s cum dripping out of him in a way
that felt gross, but also strangely erotic. He smiled as Tsukishima pressed a
kiss onto the top of his head.

“That felt so good,” he murmured, half-asleep already. Tsukishima made a sound
of agreement, then shook himself, reaching into the drawer by his bed to pull
out another energy bar. He pressed it against Yamaguchi’s lips, who made a
noise of annoyance.

“You can’t sleep until you eat this,” Tsukishima said firmly, and begrudgingly,
without opening his eyes, Yamaguchi took bite after bite until the whole thing
was gone. Then he licked Tsukishima’s fingers sensually before the taller boy
pulled his hand away with a cluck of his tongue, wiping his fingers on the
sheets. Still, he was satisfied, and pulled the blanket over them both, hugging
Yamaguchi close. Distractedly, Yamaguchi thought to himself that they should
invest in an electric blanket, but that was something he’d worry about later.

“I love you, Tsukki,” Yamaguchi murmured against Tsukishima’s skin.

“Shut up, Yamaguchi,” Tsukishima murmured back.

“Sorry, Tsukki.”

“….I love you too.”
 
 
After that weekend, everyone on the team could sense that something had
changed. Tsukishima was not as vicious to those Yamaguchi talked to, and in
fact less vicious to Yamaguchi himself. They would catch Tsukishima staring at
the freckled boy when he thought no one was looking at him, and they whispered
to each other that Tsukishima looked almost happy for once, what had that boy
done to him. No one dared mention anything to the couple in question, for fear
of getting on Tsukishima’s bad side, but they all agreed that whatever had
happened was definitely good.

Now, when Friday comes and practice is over for the night, Tsukishima and
Yamaguchi still walk off into the night towards Tsukishima’s house. But once
they’re out of sight of their teammates, Tsukishima takes Yamaguchi’s hand and
Yamaguchi leans into Tsukishima and they walk together, instead of one trailing
after the other.

Sometimes, Yamaguchi’s classmates would ask him why he hung around with a guy
who treated him like crap, who always told him to shut up and didn’t seem to
care about him. But Yamaguchi would reply that Tsukishima was actually really
nice once you got to know him, and smile such a happy, earnest smile that
whoever had asked would walk away shaking their head, thinking there must be
something Yamaguchi knew that they didn’t.

And there was, of course, a great many things that were secrets between them.
But the knowledge that Yamaguchi cherished most what that when Tsukishima said
“Shut up, Yamaguchi,” he really meant “I love you.” And when Yamaguchi said,
“Sorry, Tsukki,” in return, he really meant, “I love you too.”
