Chapter Text
"You know you don't have to do this. My energy isn't going to deplete that quickly and no doubt my brother and Mao-kun won't have a shortage of it once they get going," Rei was lounging on the bed, shirt half-unbuttoned. He was watching Kaoru with interest, trying to gauge just how invested in this the young man truly was.
"Yeah," Kaoru shrugged, leaning against the doorframe and shoving his hands into the pockets of his shorts. "But they shouldn't have to keep you alive, y'know?"
"Well, neither should you," Rei pointed out, stretching his legs out and giving Kaoru an appraising glance. "You're not obligated to me, Kaoru-kun."
"You always treat me like I can't make my own decisions," Kaoru grumbled, running a hand through his long hair and messing it up. "I'm not a child."
"Oh, trust me, I know that," Rei bared his fangs. "But compared to me you're just a pup," he gave a throaty chuckle and Kaoru blushed, staring down at the carpet.
"Is that how this is gonna go, then?" Kaoru asked softly. "Because I just want to get off."
"No, you don't," Rei sat up, leaning back against the headboard and pulling his shirt open a little more. "If you just wanted to 'get off,' you'd find a girl. You're here for a reason, and the sooner you can admit it to yourself, the more enjoyable this will be for both of us."
"It's not what you're thinking, anyway," Kaoru took a couple of steps into the room before pausing again. "I'm not attracted to you, it's your weird vampire shit that's doing it," he mumbled and Rei couldn't stop himself from letting out a tiny chuckle. "What?"
"There's no 'weird vampire shit,' as you so succinctly put it," Rei tilted his head to the side. "Admittedly, it does seem like people are...attracted to the idea of vampires. There's always something very sexually charged about our portrayal in the media, but it's not as if Ritsu or I have any special pheromones that incite arousal."
Kaoru let out a slow breath at that, looking conflicted, and Rei wondered if he'd actually convinced himself that it was something supernatural that was making him consider this at all.
"Okay. So why would you want to do it with me?" he looked up then, meeting Rei's eyes and almost seeming like he was challenging him somehow. "Why not Koga or Adonis?"
"I don't doubt either of them would," Rei admitted with a half-smile. "But Adonis-kun would likely see it as merely fulfilling a commitment, and Koga..." he chuckled.
"He fucking worships you," Kaoru grunted.
"And that's the problem. He's put me on some sort of pedestal, and I have no desire to be looked up to in that way. What I want is a partner," he sat up again, trailing his fingers along the sheets. "Isn't that what you told me you wanted, Kaoru-kun? For us to be equals?"
"Yeah, I meant as idols, but..." Kaoru trailed off. "Sakuma-san, I..."
"Call me by my name," Rei interrupted him. "At least for this."
"Then drop the -kun," Kaoru replied. "Makes me sound like a child."
"Kaoru," Rei lowered his voice intentionally, holding out his hand. "Come here."
Kaoru bit his lip, still looking unsure before he walked slowly toward the bed. "Rei..."he said the name as if it tasted strange on his tongue. "You're still not a man."
"You can tell yourself whatever you want," Rei shrugged. "But you do need to get over the idea that there's something strange or wrong about two men being intimate with each other. And I believe you know that, much as you try to cover it up," he added, drawing his hand back when it became obvious that Kaoru wasn't going to take it.
"I mean, it's just a fuck, right?" Kaoru shrugged. "I come, you get your fill of energy, we don't talk about it again."
"If that's what you want, yes," Rei sighed heavily, since Kaoru was far more in denial than he had thought. He was using brashness to cover up his nerves, undoubtedly, but there was obviously some belief within him that what he was saying was true. "But to be quite honest that's never been the sort of thing I've been partial to. I believe that sex should be about pleasure, though that may be simply because I gain the most benefits that way."
"But that won't happen with me, right?" Kaoru frowned. "That whole...feeling the same as I do thing. We're not bonded," he pointed out and Rei nodded.
"True, but we do have a connection, and I should at least be able to feel an echo of what you are," he smiled sadly. "But as I've said all along, it's entirely up to you what we do or don't do."
"Ah, fuck it, I've never been afraid of sex and I'm not starting now," Kaoru had a determined glint in his eyes and he stopped to strip off his shirt, tossing it to the side before moving onto the bed. Rei grinned, holding out his hand once more and pulling Kaoru forward as soon as he grasped it.
"So," he leaned back again, sliding his open shirt down his arms a bit. "What do you feel like doing?"
"You've probably got more ideas than I do," Kaoru settled himself on the bed, still keeping his distance enough that they weren't touching. "I mean, you've got a thousand years of experience, right?"
"Close to it, yes," Rei agreed absently. "Although as of late I haven't been doing much in the way of carnal activities."
"So I'm just another notch in your extremely crowded bedpost," Kaoru tried to smirk but the bitterness behind his words was all too noticeable.
"Kaoru," Rei moved forward, reaching cautiously to touch Kaoru's cheek. "I thought this was just about getting off?" he questioned, trying to keep his tone light.
"You know me better than that, no matter how much I try to cover up what I'm feeling," Kaoru reached for Rei's hand and held it tightly. "And I can't...you died. You were dead. And I was holding you, and I couldn't do a damn thing about it, and that's going to haunt me forever," he admitted.
"I know. I'm sorry you had to see me like that, but the truth is that...well, you won't be the first, but you might be the last," he smiled sadly. "Regardless of how much energy my brother or Mao-kun or any of you can give me, I'm still on borrowed time. By all rights I should be dead," he pointed out.
"You're not helping," Kaoru moved back again. "You make it sound like I'll be fucking a corpse."
"Well, technically..."
"Don't say it," Kaoru sighed, staring down at the bed. "Why is this so hard?"
"Because you're overthinking it," Rei murmured, his shirt slipping down to his elbows when he sat up. "When you're with a girl, is it that hard?"
"I haven't actually been with that many girls, you know," Kaoru grimaced. "And no, but I know what I'm doing with them."
"So?" Rei leaned forward, setting his hands around Kaoru's waist. "This should be easier. We have the same anatomy," he pointed out, rubbing his thumbs just above Kaoru's hipbones. "And you don't have to worry about getting me off."
"Hey, I pride myself on being a good lover," Kaoru let his hands rest on Rei's chest, fingers spreading out, just touching. "I don't want to make you do all the work."
"Oh, I won't be," Rei grinned, shifting himself a little closer again. "Do you want to fuck me, Kaoru?" he whispered, and the veritable wave of lust that came from Kaoru at the words only made his smile widen. "Is that a yes?"
"How do you..." Kaoru swallowed heavily.
"I can taste your arousal," Rei murmured. "Hmm, it's been a long time since I could feed on it like this," he breathed in slowly, savouring it.
"That's kind of creepy, man," Kaoru laughed, sounding nervous. "But, uh, you'd let me?"
"Yes," Rei tried to control himself and keep his mind clear of the lust-fuelled fog that was already starting to come over him. "It's rather easy, all things considered, since I don't require any preparation. My body is essentially intangible, made up of shadows and darkness, and this human-appearing vessel is easy enough to manipulate when needed."
"Huh," Kaoru blinked, frowning a little. "You...you're really not human, are you?"
"I thought we'd established that?" Rei tilted his head to the side.
"I mean, yeah, but it's so..." Kaoru's hand was still on his chest and he curled his fingers in. "What are you?"
"A monster," Rei shrugged. "I don't know where I came from, or how I was created, but I was never human."
"I think you are," Kaoru was looking at him seriously. "I mean, maybe it doesn't matter if you are, because I think of you as one," he sighed and Rei laughed softly.
"Being with you all makes me seem more alive," Rei nodded, his fingers sliding through Kaoru's long hair.
"But you...you feel things, right?" Kaoru blinked.
"This is getting very deep for just wanting to get off, Kaoru," Rei moved a little closer, leaning in. "Can I kiss you?"
"Okay," Kaoru breathed out slowly. "Can you answer my question first?"
"I think you know the answer already," Rei was breathing against his lips now. "Tell me."
Kaoru let out a shaky breath and touched his lips to Rei's almost hesitantly, his hands moving to grip Rei's shirt where it was hanging from his arms. "Rei, I..."
"Yes?" Rei whispered, barely loud enough to hear.
Kaoru kissed him instead of replying, pressing his body closer. Rei let his fingers tangle in Kaoru's hair, tilting his head and letting the kiss deepen. The boy knew what he was doing, Rei had to give him that, but he could also tell that Kaoru was nervous and it was endearing in its own way.
Kaoru pushed the shirt down his arms, sliding it off and tossing it aside, and he pressed Rei back against the headboard and swung his leg over Rei's hips to straddle him.
"Mm, you don't have to move that quickly," Rei broke the kiss long enough to speak. "We have time, Kaoru."
"I know," Kaoru nodded, bracing his hands on Rei's chest before leaning in again. The kiss was less frantic this time and Rei tried to project as much calmness and comfort as he could. Kaoru gasped a little, breaking away and looking at Rei with wide eyes. "What did you..."
"Could you feel that?" Rei slid his hands up Kaoru's back. "I wasn't sure if it would work, to be honest."
"Is that...a bond thing?" Kaoru tilted his head to the side.
"Mm, it's supposed to be," Rei blinked slowly, thinking. "But then, I haven't really been involved with anybody that I wasn't bonded to, so I can't say if it's unusual that this is happening."
"It's weird," Kaoru wrinkled his nose.
"I won't do it again," Rei sighed, and he was beginning to think that he'd read Kaoru wrong all along. "Should we get on with it, then?"
"Uh..." Kaoru sat up. "I'm not...I don't...like getting close to people," he crossed his arms. "And what you just did..."
"I apologize, then, if it felt intrusive," Rei removed his hands from Kaoru. "If you want this to be truly impersonal, I'll do my best to accommodate you."
"No, that's..." Kaoru let out an annoyed-sounding huff. "When I do this with girls, it's never been with somebody I know, y'know? So I try to be respectful and romantic and a perfect lover and not let them see anything other than that. I'm not used to somebody seeing me," he admitted. "With you, it's like I'm stripped bare, and it's uncomfortable."
"I see," Rei touched him again, wrapping his arms around Kaoru's waist. "I promise I'm not judging you, Kaoru. My attraction to you is based on what I've seen of you over the years. I know you have a kind heart and that you care a lot, and there's nothing shameful about that."
"I’m not used to people seeing right through me the way you do," Kaoru laughed softly. "But I guess it's okay."
"It is. Be honest with yourself and enjoy this for what it is," Rei leaned in, pressing his lips to Kaoru’s shoulder. "But I'll still try to separate my reactions from yours, if you'd prefer it."
"No," Kaoru sighed and placed his own arms around Rei's body, sinking into the embrace a little. "I want this, Rei. I wouldn't have come here if I didn't. I mean, I like knowing that I can help you, but I'm not that selfless."
"Well, I'd guessed that," Rei chuckled, kissing up Kaoru's neck to his mouth again. He could feel that Kaoru was indeed more relaxed this time, his body pliant in Rei's arms. "But I still want you to know that you don't have to do this tonight. Or keep doing it," he added, even though he had no idea if that was even on Kaoru's mind.
"We'll see," Kaoru smirked against his lips, the corners of his mouth turned up enough that Rei could feel it when they kissed again. "You should take your pants off," he murmured.
"Mm?" Rei pulled away, sliding his hands down Kaoru's body and slipping them into the back pockets on his shorts. "I should, should I?" he purred.
"Yeah," Kaoru pushed back against his touch.
"You could do it for me, since you're sitting on me anyway," Rei lifted his hips a bit and Kaoru rolled his eyes, reaching down to undo the button and zipper and shoving the pants down as much as he could.
He moved back onto his knees so that Rei could shift enough to get them down his legs. "Can you get hard?" he hesitantly touched his fingers to the front of Rei's underwear and the vampire shrugged.
"Yes. If you are."
"Oh," he hooked his fingers in the waistband of Rei's boxers, pulling them down and leaving both them and Rei's pants tangled around his ankles. "Can I touch you?"
"Yes," Rei had to smile at that. His breath hitched a little when Kaoru's fingers brushed over his cock for the first time, his hips canting upward unconsciously.
Kaoru's face was unreadable, his eyes narrowed a little. "Does it feel good?"
"Objectively, yes," Rei nodded. "But nothing's going to happen, so there's really no point.” He was used to it after so long, but sometimes he did wonder what if felt like to have an actual orgasm and not just to feel the echoes of it happening to somebody else.
"Okay," Kaoru breathed out slowly, looking like he was steeling himself for something. He scrambled off of Rei long enough to shove his own shorts and underwear down, tossing them aside and standing there naked.
"You know," Rei smirked, rolling onto his side and propping his head up on his hand, "when I said my attraction to you was based on what's inside, that didn't mean I thought the outside was unattractive."
"I know," Kaoru grinned cheekily. "I mean, look at me."
"Look at you indeed," Rei said, his voice low and throaty. "Come here," he beckoned Kaoru closer and this time he came without any hesitation, laying his body on top of Rei's. "Still anxious?"
"Mm, it's better now," Kaoru shrugged, and Rei could feel the other man's cock nudging against his hip as it started to harden. "You're, uh, really good-looking too. You know. For a vampire," he tried to sound casual.
Rei kissed him in response, his hands gripping Kaoru's ass and pulling him in more. Kaoru groaned into his mouth, returning the kiss eagerly and rubbing his cock against Rei's hip. "There's lube in the drawer," Rei gestured vaguely before his hands were back on Kaoru's skin, not feeling any desire to stop touching him anytime soon.
"I thought I didn't need it?" Kaoru gasped, his tongue tangling with Rei's as the kiss turned sloppy and open-mouthed.
"I don't," Rei could feel himself getting hard now, his body mirroring Kaoru's, and the scent and taste of arousal on his tongue was nearly enough to drive him wild with need. "But it'll be easier for you..."
"Okay," Kaoru tore himself away reluctantly, opening the drawer and feeling around until he came back with the bottle. "Do I just..."
"Mm-hmm," Rei moved back to kissing his neck now, dragging his tongue along Kaoru's skin and feeling the rapidly fluttering pulse underneath.
"Protection...do we need..."
"No," Rei scraped his teeth along Kaoru's throat and the other man let out the most delicious moan at the action. "Vampires are immune to human diseases and there's nothing that I can really pass to you, either," he promised. "Like I said, I'm just darkness."
"You're not," Kaoru's voice was trembling a little. Rei reached between them to grip his cock, stroking slowly and smearing his fingers through the wetness collecting at the tip. "Fuck...you're..."
"Because of you," Rei hummed, and he could feel how warm his skin was in that moment, how hard his own cock was. "Fuck me, Kaoru. Please."
Kaoru made a sound of pure need, nodding furiously. "How..."
"Let me ride you," Rei flipped them over, reaching for the lube and uncapping the bottle. He ran his slicked hand over Kaoru's erection, lingering a little and watching the other man's eyes slide closed while his mouth dropped open in pleasure. "Okay?"
"Yeah. Please," Kaoru shifted so he was leaning against the headboard, his hands shaking a little when he settled them on Rei's hips.
"This is going to feel weird," Rei warned him, letting his body dissolve and then re-form around Kaoru's cock, and he could hear the other man gasp when he was solid again.
"Holy fuck, you weren't kidding," Kaoru laughed, sounding on the edge between incredulity and hysteria. "Rei..."
Rei cupped his cheeks, leaning in to kiss him gently. "Is it good?" he asked, rocking back a bit. In all honestly, he couldn't feel much besides a dull sort of pressure, but he knew the sensations would be much stronger for Kaoru.
"You're so tight," Kaoru hissed, grabbing at him and pulling him in. "And hot..."
"That's all you," Rei reminded him, whispering against his lips. "You're the one making me human right now."
Kaoru took a shaky breath, starting to move his hips slowly. Rei braced his hands on the young man's chest and rocked back against him, trying to match his timing.
Maybe it was strange, that Kaoru was falling apart beneath him and yet he was perfectly composed. It felt nice, certainly, but that was all it would ever be.
"Hey," Kaoru shivered, reaching for him. "You don't look like you're enjoying this."
"I'm enjoying it as much as I can," Rei nodded, though he knew Kaoru was likely feeling guilty about it regardless. "But..."
"But what?" Kaoru's hands were sweaty, sliding on his hips now. "Tell me."
"Will you let me bite you?" Rei stopped moving, looking at Kaoru seriously. "I'll be more...connected to you. And it'll be better for you," he added softly.
"I thought you didn't like blood?" Kaoru looked confused. Rei reached to brush his hair aside from where it was sticking to his forehead, hand moving to cup his cheek.
"I don't, particularly, but in this case..." he bared his fangs. “I want to drink," his voice came out as a growl, and Rei knew that it really had been too long since he'd formed any sort of bond with a human if he was craving blood.
"Okay," Kaoru held him tighter. "I trust you."
"Thank you," Rei smiled kindly, leaning forward and resting his fangs against Kaoru's neck. He started to move his hips again, letting the natural rhythm of his body push him forward enough that his teeth broke the skin.
The first gush of sweet lifeblood into his mouth made him moan with need, and he heard Kaoru let out a tiny whimper. He latched his mouth onto Kaoru's skin, holding his head in place and being sure to keep his body moving.
"Rei...oh, fuck..." Kaoru's voice sounded wrecked, raspy and broken, and he was clutching at Rei in desperation.
Rei couldn't really respond but he snapped his hips down harder, sinking fully onto Kaoru's cock before lifting himself off again. He knew he couldn't drink much more but the pull was intoxicating, the energy flowing into his body and leaving him feeling more alive than he had been in years.
"Rei...Rei, please," Kaoru's hands were scrabbling at his back, his hips pumping frantically. "Please, I need..."
Rei growled, tearing himself away from Kaoru's neck with far too much reluctance. He licked over the puncture wounds to close them, tangling his fingers in Kaoru's hair and crashing their mouths together almost violently.
Kaoru whined, his entire body shaking now. "Rei, I need to..." he gasped when Rei circled his hips slowly, clenching around his cock and trying to bring him over the edge.
"Come for me, Kaoru," he murmured, baring his stained teeth. "Make me feel it."
Kaoru's only response was a noise that sounded somewhere between a gasp and a sob, nails digging into Rei's back and his hips driving up one last time as he came.
Rei kissed him through it, holding him tightly and feeling him inside, and he decided to let himself get lost in it. His own cock pulsed, nothing coming of it, but he could feel Kaoru's orgasm and the intensity of it, even without being bonded, still took his breath away.
Kaoru slumped back against the headboard, his breath coming fast and shallow. "Easy," Rei stroked his sweaty hair back, kissing his forehead and trying to project calmness again even though, honestly, he wasn't that calm himself. "Easy, Kaoru, you're okay."
"Woah," Kaoru let out an incredulous bark of laughter. "Shit, Rei..."
"That was good?" Rei asked softly, pressing more kisses against Kaoru's closed eyelids and over his cheeks.
"I've never come that hard before," Kaoru's voice was slurring and his head lolled to the side. "Thank you."
"No need to thank me. I rather enjoyed that as well," he assured the young man.
"Yeah? Good," Kaoru hugged him and Rei snuggled against Kaoru's shoulder, letting him take whatever time he needed to recover.
He'd never admit it, of course, but he needed a bit of a break, too.
000
"So...can we do that again sometime?"
"Mm?" Rei yawned, his cheek resting on Kaoru’s shoulder and his arm thrown haphazardly across the blond's chest. Kaoru smelled clean now, freshly showered and drinking a sports drink at Rei's insistence – he had taken a fair bit of blood, after all.
"Uh, I mean, if you want to," he blushed and cleared his throat, looking away.
"Kaoru," Rei laughed softly. "Of course we can. I was hoping you'd want to."
"Good," Kaoru was stroking his back, fingers skimming up to pet his hair and then working their way down again. "Because that was amazing."
"Ah, I see, you only want me for the good orgasms," Rei teased, kissing Kaoru's shoulder and playfully tracing two fingers over Kaoru's chest. He absently rubbed his thumb over a flat nipple, feeling it harden under his touch as Kaoru groaned quietly.
"No fair," he complained, sounding like he was pouting. "And it's not that. It's...you. Everything. I...want you like I've never wanted anybody else."
"I wish I would have known all it took to make you honest was coming really hard," Rei slowed his hand down, letting it just rest on Kaoru's chest.
"I'm serious. I know we're not bonded or whatever, but there's still...something there, right?" he sounded almost afraid to ask that.
"There is. We have a connection, certainly," Rei promised. "And that's more than enough for me."
"Oh. Good," Kaoru cleared his throat, reaching to take a sip of his drink. "I mean..."
"I know," Rei knew he probably couldn’t outright say his feelings yet, but Rei could sense them regardless. He sat up enough to kiss Kaoru, slow and languid. "What do you say to 'sometime' being 'now?'" he murmured, feeling Kaoru's cock already starting to take interest again,
"Uh. Are you..."
"As long as you are, my body will follow," he reminded Kaoru. "And it would be a shame to not take advantage of your youthful stamina, Kaoru-kun," he said it teasingly that time.
"Koga’s right, you know? You are a bastard sometimes," Kaoru pressed their mouths together again, wrapping Rei in his arms.
"I know," Rei whispered, smiling into the kiss and letting Kaoru draw him back down onto the bed.
He knew, then, as he'd known for far longer than he would ever care to admit, that Kaoru would be his last.
But that was fine.
In fact, it was more than fine, and if he could get this much pleasure from his twilight years, he would have no regrets at all when his time finally came.
"Hey. You looked way too serious there for a minute," Kaoru cupped his cheek, gazing at him with concern. Rei shook his head, curling his body against Kaoru's.
"Leave an old man to his musings sometimes, hmm?" he let Kaoru roll him onto his back, laughing rather freely and getting a grin in response.
Yes, Kaoru was definitely going to keep him feeling younger, and he was going to enjoy every single moment of it.
