Work Text:
Reigen was considering his options while staring listlessly into the empty work fridge. This never happened to him. He got his rations delivered to his door and then budgeted. He planned, and he made sure not to drink more than he should. He made it last. How had this happened? Oh. That exorcism job last week with the possessed rich girl-- that ghost had really given him a good thrashing before Mob had managed to get rid of it. When he’d gotten home late at night, almost early morning really (close call), he’d chugged three packets of blood without thinking about it on automatic, bruises, torn skin, sprains, and even some breaks screaming at him to eat and fix this. He hadn’t even bothered heating it up first, drinking it cold like a desperate, starving vampire would from a days old corpse back in the old days.
He really should have planned around those three missing packets. But, well, he’d been exhausted. And unusually swamped with work after that. And he’s just an idiot, okay? Reigen still doesn’t know how he’s allowed to adult. Anyways.
He could call the blood bank and explain. You’ve already gotten your allotted blood for the month, they’d say. But I was injured, he’d say, but much more suavely than that. Oh? they’d say. How were you injured? they’d go on. Well this ghost body slammed me-- he’d say, and then they’d slam the door in his face, refusing to invite him back him until he was ready to spew something besides ridiculous stories about things that obviously don’t exist.
Vampires and werewolves? An obvious fact of life. Ghosts and espers? Get out.
Reigen hadn’t really ever appreciated the non-logic of that until he was actually on the other side of that argument, which he supposed was just the way of life.
He could lie to the blood bank about how he got injured. And desperately hope that he wasn’t caught. He was a born liar, he could do that! He’d just have to make sure not panic under the pressure of knowing what happened to vampires who tried to scam the blood banks for more blood than they needed. Ha. Haha. He could do that, he’d performed under great pressure before--
“Reigen-san, are you okay? You’ve been staring into the fridge for a while now.”
He startled, but thankfully managed to restrain any revealing noises. He took a deep breath, closed the fridge, and turned towards Serizawa with a dazzling grin. “I’m perfectly alright, Serizawa-kun! I just got distracted thinking about the last job.”
“You mean the lady who though her cat was being haunted?”
“Yes, that’s the one.” He nodded assertively and stood up from his crouch (his legs protested, proving that he really had been zoning out for too long there), walking back to his desk. “I was just working out a theory that, uh, certain breeds are haunted more often than others! Statistics and such.”
“Oh…” Serizawa said, and was then promptly interrupted by Reigen’s stomach embarrassingly loud rumbling. He cleared his throat uncomfortably and didn’t look at Serizawa as he sat down.
“Do you want me to heat you up a cup of blood, Reigen-san?” he asked with a small smile.
“Oh, that’s fine--” But Serizawa had already opened the fridge, which only contained a container of Mob’s milk and a lunch he could heat up when he arrived, which wouldn’t be for a few hours still. He made a mental note to buy more of those lunches tomorrow. He’d heard there’d be a sale on the other side of town, too…
“Um… I think you forgot to bring your lunch today, Reigen-san?” Serizawa said uncertainly. Good old Serizawa. He’d make your excuses for you. Which wasn’t so great in general (example: Touichirou), but Reigen was a responsible adult who tried not to take advantage of it too often, unless he had to. Like now.
“Yes, that must be what happened,” he agreed.
His stomach grumbled loudly again.
“Do you want to go home and grab--”
“No, that would be terribly unprofessional,” Reigen interrupted. He paused and thought for a moment. “Because I’m the owner and boss of this company. If you ever get hungry and there isn’t any food in the mini fridge, you are of course obliged to go and get yourself something so long as you let me know first.”
“Okay,” he said weakly. Reigen may have come on a little strongly there. He felt a twinge of guilt.
“Right,” he said, just to fill the silence, and then opened his laptop to look busy. He wished he could smoke. Maybe it’d help him feel less hungry. But he’d stopped smoking at his work place after he’d hired Mob, and so all of his cigarettes were at home. And he’d just made a whole thing about him not walking out in the middle of the work day to get himself shit. Would it be unprofessional to make Serizawa go and buy him some cigarettes? The answer was yes. Obviously.
Reigen resisted the self defeating urge to Google pictures of blood.
He didn’t know how much time he’d wasted on surfing the internet, but it was some time before he heard a soft, “Um.”
Reigen looked up. “Yes, Serizawa-kun?”
“You seem… pretty hungry.” He said. He wasn’t turned around in his desk to look at him while he was talking. Reigen knew that he wasn’t trying to be rude, he just needed a little distance sometimes when talking to people. He couldn’t see the whole of his face, so he wasn’t sure, but was that a blush?
“Yes, but let’s not talk about it. Dwelling on how hungry you are will only serve to make you feel hungrier.”
“Ah, yes, sorry, Reigen-san! But I was thinking, since you don’t want to leave to go and eat before the end of the work day, and the day just started, and you seem so hungry …” he trailed off into mumbling too quiet for Reigen to decipher.
“I’m sorry, could you repeat that?” he asked. “I didn’t quite hear you.”
Yep, that was definitely a blush. Oh, and now he was hunching his shoulders too. He wondered if he should try and push Serizawa to say what he wanted to say, or let him off the hook. Which one would be for the best?
“... could drink some of my blood,” he mumbled, and after a moment of incomprehension Reigen choked on his spit.
“I--” definitely hadn’t misheard that. Should he say it anyways, give him a chance to back out? Or would he be forcing him to back out? There was no doubt in his mind that Serizawa had had to muster an enormous amount of courage to say it the first time, who knew if he’d be able to manage it a second? But wasn’t it for the best if he made Serizawa act like he hadn’t said what he said, for his own sake? He shouldn’t use him. Well, much. Not to his detriment, anyways. And this was bad, wasn’t it?
“You could drink some of my blood,” Serizawa repeated without coaxing, face flaming, his voice a little louder, as if he thought Reigen hadn’t properly heard him once again.
Well, there went that plan. But that was fine, right? Serizawa was an adult, he could make his own decisions. Except no, not really, he wasn’t used to it at all, he had trouble--
Serizawa stood up with awkward suddenness and started undoing his tie.
On the other hand, Reigen was so, so hungry. He forced himself to stop arguing himself out of a good thing that had been offered to him.
Serizawa took off his jacket and unbuttoned perhaps a few more buttons than was strictly necessary.
“Good… initiative,” he said distractedly, just barely stopping himself from saying ‘good chest’. Damn, but he was hairy. And apparently Reigen was into that? No, bad Reigen, stop it. The situation was morally gray enough as it was.
Serizawa smiled reflexively at the praise, jacket and tie tossed on his desk, shirt half undone. Jeeesus. If Reigen didn’t at least get his mouth on that neck he was going to die .
His office was small, and it only took a few steps to close the distance between them. Hands on his shoulders. Clearing his throat. Oh no, eye contact.
“Thanks… for this,” he said. “You really didn’t have to. You don’t have to. If you, you know--”
Serizawa shook his head resolutely and looked down. “It’s fine, Reigen-san. I want to.”
He wanted to. It was fine, it was totally fine. Stop freaking out.
Feeling too hot and overdressed in his suit (but why should he take off his jacket and tie, what excuse did he have to start undoing buttons), Reigen gently placed his mouth on Serizawa’s throat. Not biting straight away. He just felt Serizawa’s rabbit fast pulse with his lips, a silent and dry kiss to his throat, trying not to feel bad or turned on. Just hungry.
He opened his lips and licked a mouth sized swath over Serizawa’s skin, trying to wet it with as much numbing saliva as he could. Serizawa’s breath stuttered, his grip on Reigen’s hips tightening (when had those gotten there).
When Reigen’s teeth finally sunk in, slowly, indulgently, his unnaturally sharp canines pressing the skin down for a few moments before finally breaching the skin with an almost-pop (too dull, he had to take better care of them), he could feel his eyes roll back behind his closed eyelids. Serizawa gasped, shuddered, and his hands were gripping him so tightly that Reigen knew he’d have some bruises that he’d enjoy far too much tomorrow on his hips. Christ, but his hands were huge.
The first long pull was heavenly. Warm and filling thick blood, that delicious coppery taste. Was it just Serizawa that was unusually tasty, or was Reigen just that hungry? This was the first time he was drinking straight from a human and not a plastic bag or a microwaved cup. Maybe it was that. Yeah. Probably just that.
A second long pull. Reigen would have to be careful not to drink too much. How much was too much, now again? It was hard to remember at the moment. Dangerous.
Serizawa released a breath, much like a long sigh, and his warm breath ruffled Reigen’s hair.
A third pull. Less was safer, right? He didn’t need that much to survive. The day when he'd be resupplied was close, he could maybe make it on just this. Maybe.
He took three more long, sucking mouthfuls of blood before he was able to bring himself to stop. He concentrated on making his saliva heal Serizawa’s two small puncture wounds, keeping his lips sealed to make sure that no blood trickles spilled over and stained his shirt in the meantime. Definitely just because of that, no ulterior motives here.
Finally, reluctantly, he parted from Serizawa and his wonderful neck. Serizawa blinked dazedly and swayed, and Reigen steadied him with alarm. Okay, maybe six pulls had been too much. The next time he’d only try half so many. The next time. Reigen caught the thought and scolded himself. He’d be more careful from now on so he wouldn’t end up using his subordinate like this again. He was a responsible adult, damn it.
Serizawa slumped against him, and Reigen had to turn his face away so his lips wouldn’t end up pressed up against the spot where he’d just been happily sucking Serizawa’s blood away only moments ago. The blood lay heavy and warm in the pit of his stomach, and the feeling faintly reminded him of something else that made him blush fiercely.
Well, in theory he was a responsible adult, damn it.
“I,” Reigen said, and he was too recently sated for his mouth to feel dry but it felt like it should be, “am going to follow you home. I’m really sorry about this, Serizawa. You should’ve told me if you felt like I was taking too much.”
“I don’t feel like that at all,” Serizawa said, weak kneed and pale. “I feel great.”
His smile was way too bright to look at directly.
“Right, well, shows what you know,” Reigen said after a little coughing to buy himself time to compose himself.
“The next time you forget your lunch--”
“There won’t be a next time,” Reigen interrupted firmly. “I’ll be more careful from now on.”
“Right,” Serizawa said, sounding oddly disappointed. He brightened abruptly with the childish hopefulness of someone tipsy on blood loss. Reigen bet Serizawa was a happy drunk. “But if there is,” he said, a slight slur to his words. “I’d be happy to help, Reigen-san.” He somehow contrived to blush strongly despite the blood loss. "Very happy.”
“... Right,” Reigen said, and cleared his throat again.
Well, in his dangerous line of work, who was to say he wouldn’t end up losing a few bags of blood again thanks to ghost-related injuries? But only if he absolutely had to. And he wouldn’t take as much blood next time. Not that he was planning for a next time!
But, well. If there was.
If there was.
Reigen took Serizawa home.
