Nai’s twin brother went missing when they were kids. He always felt responsible. He was the big brother. He was supposed to protect Vash. The one day Nai was sick and his brother had to walk home from school by himself, Vash disappeared. They didn’t live far but it was already so dark when school let out that time of year. No one knows what happened.
Nai never stopped looking for him. For the first few months, everyone was on high alert looking for Vash. It was all over the news and practically the whole city knew. Over the next few years, it started to die out. People were losing faith that he would ever come home. Eventually, Nai was the only one left.
It’s been fifteen years and Nai hasn’t given up. No one will say it to his face, but everyone else is certain that he’s dead. Kids who are gone for fifteen years don’t suddenly reappear. Nai refuses to believe it. He’s going to find his little brother again.
Of course, even his efforts have slowed over the years. There haven’t been any new developments in over a decade. It’s pointless to put up missing child posters now that his brother is an adult somewhere. Nai has no idea what he looks like. Sometimes he stares at himself in the mirror and wonders what might have changed. Will they still look the same?
Nai never left July. He has a feeling his brother is still here. He can sense it. It’s like he can feel Vash’s heart beating in time with his somewhere in this big cold city. He just has to find him.
Nai’s obsession with his brother pushed everyone else away. Vash is all he has left. Their mother had died a few months before Vash had gone missing. She was the only real family they had left. Nai always had trouble making friends. With his brother gone, he has no hope.
So that’s how he finds himself wandering the city alone on a Friday night. It’s not unusual. He spends a lot of Friday nights this way. He’s not really expecting to find any signs or hints of his brother anymore but it’s a habit.
That’s why it’s such a surprise when he sees him.
It’s Vash. It has to be Vash. Nai would know his brother anywhere. He’s searched for a decade and a half and he’s finally found him. He looks the same as the day he disappeared. Of course, that’s the problem.
This boy still looks ten.
It can’t be a coincidence. This boy is a carbon copy of his brother. He doesn’t understand how Vash could still look ten after he’s been missing for fifteen years, but there’s got to be a connection. Nai can’t let him get away.
“Vash,” Nai calls out across the street.
The boy stops and looks up at him. His face suddenly floods with fear. He turns around and scurries away.
“Vash, wait!” Nai cries. He pushes past people on the street to chase after his brother.
Nai almost loses him several times, but he’s determined. He chases his brother through dark alleys until they finally reach an old abandoned house. Nai is a little way behind his brother, so Vash must think he’s gotten away safely when he slips into the old house.
Nai pushes open the door. It creaks as it swings open. The whole house is dark. It’s unnerving. His instincts are telling him it’s dangerous but he has to find his brother. He has to. It doesn’t matter the cost.
“Hello?” Nai says. “Vash?”
“How did you find me?” comes a voice from the dark.
It’s Vash’s voice. Nai would recognize it anywhere. He doesn’t know how but this is his brother. This has to be Vash.
“I never stopped looking for you,” Nai tells him. “Not since the day I lost you.”
“You should have,” Vash says. “I think it’s best if you just leave.”
“Please,” Nai begs. “Talk to me. What happened? It’s been fifteen years and you haven’t aged a day.”
A light flicks on and Nai can see him clearly. It’s Vash. He’s got the same small frame, same pale hair, same mole that mirrors Nai’s own. He’s wearing modern clothes, not what he disappeared in, and he’s got large orange glasses that make it difficult to see his eyes.
“Vash,” Nai says softly.
“You shouldn’t be here,” Vash says. His voice is still high and light. It’s nothing like Nai’s low and gravely one.
“Can you please just tell me what happened?” Nai asks. Vash seems to consider him.
“It’s dangerous,” Vash says. “If you’re smart, you’ll just leave.”
“And if I’m not?” Nai asks. “If I love you more than I fear death?”
There’s something sad in Vash’s eyes. He’s clearly trying to protect Nai from something. Yet there’s some hesitation. Maybe Vash has missed him Knives just as much as Knives has missed him.
“Alright,” Vash says. “But you can’t say I didn’t warn you.”
He leads Nai into what appears to be the living room. The house is sparse but there are some signs of life. Someone must live here. Is this where Vash has been the whole time?
“You should probably sit down,” Vash says, perching on a large armchair. “This may take a while.”
Nai walks over and sinks into the couch. Everything in the house looks old, like it’s been abandoned for decades. How did Vash come to live here?
“What happened?” Nai asks. “How did you end up here?”
“I guess I should start at the beginning,” Vash says.
“You disappeared,” Nai says. “Fifteen years ago.”
“Yes,” Vash says. “I was coming home from school. It was already dark. There was an accident.”
“What kind of accident?” Nai asks.
“A car accident,” Vash says. “They hit me and just kept driving, leaving me in the road to die.”
“And why didn’t you?” Nai asks.
“Roberto found me,” Vash tells him.
“Who’s Roberto?” Nai asks.
“A kind man,” Vash says. “He saved me. The only way he could was to turn me.”
“Turn you?” Nai asks.
“Change me,” Vash says.
“Into what?” Nai asks, nervously. He has a bad feeling about this.
Vash takes off his glasses to reveal bright red eyes. They shine in the low light. He opens his mouth wide to reveal long and pointed canines.
“A monster,” Vash growls, baring his teeth.
Nai doesn’t know what to say. His little brother is a vampire. It’s hard to believe. It seems like he’s fallen into some strange dream.
“It was a kind gesture,” Vash tells him. “Though one I sometimes regret.”
“So you’ve been living here?” Nai asks. “With Roberto?”
“And his other children, Meryl and Wolfwood,” Vash explains. “We live together and hunt together.”
“Hunt?” Nai asks. “You kill people?”
“No,” Vash says, but something dark passes over his face. “Others like us do, but our family refuses to kill humans.”
“So what do you hunt?” Nai asks.
“Animals,” Vash says. “We hunt in the night where no one can find us.”
“You can live off of animals?” Nai asks.
“It’s not pleasant,” Vash admits. “But their blood keeps us alive.”
“So why did you never come home?” Nai asks.
“Isn’t it obvious?” Vash asks. “It would have put you in danger. I wanted to keep you safe.”
“You could have told me,” Nai insists. “I spent fifteen years looking for you. Everyone else thought you were dead.”
“In a way, I am,” Vash tells him. “And if I told you, you would have tried to follow me. You would follow me to the ends of the Earth.”
It’s true. Nai can’t deny that he would follow his brother anywhere. If he had known where Vash was, he would have tracked him down immediately, no matter the danger.
“That’s why I think you should leave now,” Vash finishes.
“What?” Nai asks. “No way. I can’t leave now. I just found you again.”
“You should leave,” Vash says. “And soon. I don’t know when my family will be back.”
“Please,” Nai begs. “Don’t make me leave. Not yet.”
“You’re in danger,” Vash tells him. “Every second you’re with me. I can’t do that to you.”
Nai stares at his brother for a moment. Vash looks sad. He must not want Nai to leave either. There has to be another way, a reason Vash will accept to let Nai stay with him.
“What if you turn me?” Nai asks.
“Of course not,” Vash says. “You don’t understand. You don’t want a life like this.”
“I want a life with you,” Nai tells him. “That’s what I want more than anything else in the world.”
Vash gets up and walks over to him. It’s surprising how intimidating he can be when he still looks like a child. He walks with purpose. Nai feels his heart racing.
“You’ll never see your friends or family again,” Vash warns him.
“I don’t really have that anymore,” Nai admits.
“You’ll never see the sun,” Vash says firmly. “You’ll be a monster that lurks in shadows in the dead of night.”
“If it’s with you,” Nai says. “I’ll do anything.”
“Alright,” Vash says. “Get down and show me your neck.”
Nai slides down off of the couch to his knees. He unbuttons the top button of his shirt and bares his neck to his little brother. Vash walks closer and kneels before him.
“This is going to hurt,” Vash tells him. Nai nods. That’s fine. Whatever it takes to stay with Vash. Then Vash sinks his teeth into him.
The bite hurts, but it’s bearable. He groans as his brother’s teeth dig into his neck. He can feel blood dripping down his chest. It’s soaking his white shirt. It seems to take some effort on Vash’s part but he pulls off of him. His brother stares back at him, panting, his mouth covered in Nai’s blood.
“Get ready,” Vash says. Nai doesn’t understand what he’s supposed to be getting ready for when suddenly every cell in his body is on fire. He drops to the floor and screams. It’s agony.
“What’s happening?” Nai cries.
“It’s the venom,” Vash tells him. “If you want to be turned and not just die here, you’re going to have to drink some of my blood.”
Nai looks up. Vash is standing again. Nai watches as he bites his own wrist until crimson pours down his forearm.
“Sit up,” Vash tells him.
Nai forces himself to sit up, despite the pain. He opens his mouth as Vash holds his dripping arm above him. Some of his brother’s blood falls to his mouth and hits his tongue. He swallows. Slowly, the burning inside him fades. He blinks up at Vash, feeling strange.
Everything seems suddenly sensitive. The traffic from the street outside is deafening in his ears and the low light of the lamp practically blinds him. He sinks back into the sofa, trying to adjust to it all.
“I know it’s hard,” Vash says. “Just relax.”
Nai blinks up at the ceiling. He’s not sure how long it takes, but eventually his senses calm down enough to meet his brother’s eyes again.
“How do you feel?” Vash asks.
“I’m not sure,” Nai says, still a little disoriented. Vash laughs.
“That’s normal,” Vash says smiling.
“Thank you,” Nai says. “For turning me. For letting me stay.”
“Of course,” Vash says. “You’re my brother. I love you.”
Nai stares up at him. Vash kneels down in front of him.
“I suppose you’re my son now,” Vash says. “Aren’t you?”
That has Nai’s heart pounding. He can feel his blood pulsing in his ears. It’s his brother’s blood now, too. He has his brother’s blood in his veins.
“You’re so beautiful,” Vash breathes. He leans forward to kiss him.
It’s a little surprising. He’s always loved his brother. He knew it was more intense than most people felt towards their siblings. Even before Vash disappeared, he knew his love for Vash wasn’t quite normal. He has always hid that part of himself away.
It’s freeing. He and Vash have left their humanity behind. It makes sense that they could leave their shame behind too. He eagerly kisses his brother back.
Vash is so much smaller than him. They’re still twins, Nai can feel that they still had the same soul, but he’s much larger than Vash now. Vash’s lips are so soft and delicate against his. Vash crawls onto his lap and Nai can barely feel his weight.
Vash might look and sound like a child, but he certainly doesn’t kiss like a child. He must have had some kind of experience. Nai briefly burns with jealousy that someone had gotten to his brother before he had but it’s pointless to worry about. For now, Vash is his.
“I’ve missed you,” Vash tells him. “Every day that I’ve been gone. It’s driven me crazy being apart. I felt a little obsessive, knowing I needed to stay away but desperately hoping to see some sign of you.”
“Really?” Nai asks.
“We’re meant to be together,” Vash says. “It’s agony being apart. I tried to keep up with you, watching you but staying just out of sight. I knew it was dangerous but I had to know you were alright.”
Nai doesn’t know what to say to that. The knowledge that his brother was just as desperate as he was makes his heart pound.
“It was hard to fight my thirst for blood when I was first turned,” Vash tells him. “But it was harder still to fight my thirst for you. I was overcome with guilt. I felt that I really was a monster. But now I have you and I don’t care anymore.”
“I’m glad I found you then,” Nai says.
“I am too,” his brother says, smiling at him.
Vash kisses him again. He reaches down and unbuckles Nai’s belt. Nai groans as Vash pulls his cock out. His brother’s touch is feather light on his sensitive skin. Vash’s tiny hands are stroking him and he’s so hard he’s going to go crazy.
“I want you to fuck me,” Vash breathes. Nai kneels in front of his brother, panting. “Can you do that?”
Nai nods eagerly. Vash smiles. He gets up and slowly slides out of his pants. Nai watches breathlessly. Once Vash is undressed from the waist down, he crawls back onto his brother’s lap.
“Are you ready?” Vash asks, taking Nai’s cock in his small hand. Nai nods again. “Good.”
Vash gently eases himself down onto Nai’s cock. Nai groans. His hips instinctively try to buck up into his brother. Vash is so small. Nai is worried he’s going to hurt him. He knows logically that Vash is a powerful vampire, stronger even than Nai, but the thought is still there in the back of his mind.
“You feel so good,” Vash tells him.
Nai can’t imagine Vash feeling better than he does. Vash’s cunt is so hot and tight. Nai isn’t unreasonably endowed, but he still feels like his cock is too big for Vash’s small frame. Vash doesn’t seem bothered though. He’s so wet, dripping back down onto his brother.
Vash kisses him again. The blood on their mouths mix together until Nai can no longer tell whose is whose. The metallic taste fills Nai’s mouth. He’s never liked the taste of blood before but now it fills his stomach with a heat he can’t put into words. His fingers dig into Vash’s hips as his brother rides him.
Vash pulls off his mouth and leans forward to whisper in his ear.
“Is it good?” Vash asks. “My son?”
“Yes, mother,” Nai groans.
Vash takes one of Nai’s hands. It’s so much bigger than his own. He brings it between his own legs.
“Touch me,” Vash tells him.
Nai eagerly does as he’s told. He rubs at Vash’s clit and his brother moans. Nai can feel Vash tighten around him.
“I love you, Vash,” Nai whines. “I’m so glad I found you again.”
“I’m glad you found me, too,” Vash tells him.
He’s still riding Nai. For such a small boy, he’s moving very forcefully. Nai is barely hanging on. His fingers dig even deeper into his brother's delicate hips.
“I’m close,” Vash pants. “Keep going.”
Nai tries desperately to hold on. His hips are thrusting desperately up into his brother’s pussy. He tries to focus enough to rub at Vash’s clit. Suddenly Vash bites down into his brother’s neck as cums. Nai gasps as his brother’s teeth sink into his neck at the same time as his pussy spasms around his cock.
Even after Vash has come down from his orgasm he keeps riding Knives with his teeth still deep in his neck. Nai can’t hold on any longer. He grabs onto Vash’s hips and holds his little brother down in his lap.
“Ah, Vash,” Nai gasps as he fills his brother’s tiny cunt with cum.
Vash gives Nai a moment to breathe before climbing up off of him. Nai is still panting as Vash grabs his pants and pulls them back on. His little brother looks so composed again already. It takes a little longer for Nai to put himself back together.
“Are you ready?” Vash asks as Nai tucks himself back into his pants. “The rest of the family will be home soon.”
“I think so,” Nai breathes.
His life is about to change in a huge way. Maybe he hadn’t thought it all the way through but he couldn’t lose his brother again. Nothing was worth that. If he has Vash by his side then he can do anything.
“Alright then,” Vash says, smiling. “Let’s go.”
