Yes.
Katsuki is a cheeky brat who doesn't like to be told what to do. That included shitty nerds who told him that he should "Go home and patch up" right after he was attacked by a stupid vampire on the street. Yeah, he'll go to his house for a cut on his arm and allow his Mother to throw an unreasonable tantrum and never let him go outside the house again. As if.
While it may be acceptable and even expected for a Mother to be worried over their child's safety, and it would be reasonable for his old hag to throw a fit if she finds out he was attacked by a vampire of all things, he remembered all the times that he had gotten injured in the past. One time in particular where he scrapped his knees and elbow while playing outside with some friends; she found out and forbid him from even having friends because "he couldn't handle the responsibility."
That was one lonely summer.
Even more lonely was the time she actually took him to the park! He was so excited as a little kid who finally convinced her to take him somewhere he could run and play and swing around and just be a little kid. One fucker punched him for not wanting to get off the big slide and that was it, his Mother refused to take him anywhere ever again. He was allowed to play inside, but she had to meet his friend's parents and have lunch with them a few times to get to know them and feel out their way of parenting and maybe she would think about letting one approved friend over at a time for 30 minutes to play under supervision in their living room where she could watch.
He stopped bothering to even make friends at that point, her habits too annoying to explain to people that dared try to make friends. It was easier to just be an unlikable person, because at least then nobody got tempted to make him wish for anything else. At least then being a social pariah was his choice. He was perfectly fine sitting in his room reading books and Allmight comics when he was done with the downstairs studying sessions his mother always monitored at home.
Kirishima was different. That fucker had to be some kind of masochist to still be friends with him even after all this time of dealing with Katsuki's distasteful personality. He liked Kirishima, for sure, but he would never admit that to the redhead. And though the guy knew something about what life was like living with his Mom, he didn't fully understand.
Past that, Deku was even more different. Deku was his escape. Deku was everything his mother hated. Deku made him feel safe despite the fact that his species spelled danger. He felt free. His friendship made him feel like he was flying, like nothing was tethering him down to Earth and yet he could land safely at any time that he wanted. Deku intimately knew what it was like for Katsuki at home. He listened, he analyzed without being told anything, and he understood. That wasn't something that Katsuki had ever been familiar with before, which made the vampire particularly and ironically special to him.
Katsuki didn't go home despite being told to, because no way was he going to be able to explain why his arm had blood dripping down it if his parents walked in on him cleaning up. At least this way, he thought as he entered the Midoriya home through the back door, he could clean up and start wearing long sleeves until the cut healed and he could blame the scar on a bus accident or something.
He entered Deku's kitchen and went straight to the medicine cabinet, grabbing bandages and the peroxide. He was on his way over to the dining table to clean his wound when Deku appeared out of nowhere at the entrance from the hallway.
Katsuki hated the way that he jumped, startled by the fact that he hadn't heard the vampire approach and he hadn't been there a second ago. He was quiet like any other predator should be.
"You're very strange." Deku said.
"What do you mean." Katsuki humored the vampire humorlessly as he sat his happy ass down and grabbed some wipes to clean the blood. The sting of the peroxide burned, but he was not willing to risk getting a shitty infection too. He could see it happening to him with his luck, no way would he be able to get antibiotics without his Mother finding out for sure.
"You are fully aware that I could break at any moment and attack you. It would be instantatious, deadly, and you probably wouldn't even know what happened until the life was already leaving your eyes." The way he talked about it so casually made Katsuki shiver, but he was sure that it wasn't fear that he felt as Deku spoke, "Yet you tempt me by coming here smelling so heavily of blood that it's saturated all over my walls now."
Katsuki just looked at him and shrugged, wiping away the last of the dried mess on his arm. He seems to have finally stopped bleeding and now that he could see the wound he sighed in relief that he wouldn't need stitches. "I'm confident in your ability to control yourself."
"Sure, but my confidence in myself is wearing very thin, Kacchan."
"I just think if you were able to keep from breaking the moment that asshole spilled my blood across that ally, then I can for sure trust you any other time." He covered the cut in a small piece of gauze before covering it with two large bandaids, the sticky beige patches clinging to his flesh comfortably.
"You can call it trust, but I think you have a danger kink."
Katsuki gave Deku a long look. The nerd's eyes hadn't changed from the deep red his hunger pains gave him and he was honestly getting tired of it. The vampire looked so needy and hopelessly pathetic that Katsuki was at the end of his rope in frustration.
"What that fucker said about the way I smell. Is my scent that different than others?" He asked curiously. Trying to ignore that cliché about killing the Kat.
His friend's silence and the sheer deprival in his red eyes was all the answer that Katsuki needed. "Kacchan, please don't torment me by making me talk about how good you smell and how hard you are to resist compared to others."
That was it.
Katsuki snapped.
He was done with this shit.
The blonde walked right up to Deku and grabbed his hand. "Follow me."
Deku doesn't fight him nor does he resist as he is led upstairs to his bedroom, but he does stammer out questions of Katsuki's intentions as the blonde shut the door to his bedroom with a click of the lock.
Katsuki walks over to his friend's bed and sits down, taking off his shirt.
"What are you doing?" The vampire asks, standing by his now locked bedroom door awkwardly as smooth muscles were exposed. He had never seen Katsuki shirtless before, had only ever heard the workout routine from the next house over.
Oh.
"Come here," Katsuki reaches a hand out and Deku slowly walks forward to take it. He is then pulled closer into Katsuki's lap.
"What-" Straddling the human's legs, it registers to the vampire that he's never been this close to anyone other than his Mom before in his life. But this was different than the hugs his Mother gives him or the distant memories of his Father playing with him as a child. This type of proximity made him swallow thickly as he had nowhere else to put his hands but on the blonde's bare shoulders.
"Shut up," Katsuki interrupted his stutter. "I know you're hungry, so fucking feed already."
"What?!" The vampire exclaimed, but Katsuki was no longer willing to respect his wishes to keep starving himself. "Kacchan, I'm not sure this is a good-"
"Hush," he stopped Deku's protesting with a hand over his mouth, and the vampire's brain short circuited because physical contact made him weak. He didn't know what to do. His brain wasn't articulating complete thoughts and his arguments were coming out broken. Katsuki's touch was like lip balm soothing his parched skin and he didn't know what to do anymore, not with warm flesh under his fingers as he clutched at strong shoulders. Shoulders he didn't want to let go of or he might fall and never be able to get up again. God, his skin was so soft.
"I'm your friend okay, shitty nerd?" The human continues, not removing his hand from Deku's lips to give him any opportunity to protest anymore. "We've known each other for months now, and have I ever been a rat to you? Have I ever lied even once?"
Deku sniffled, and the crybaby part of him started to show. His eyes were glassy and the shake of his head was small. Too overwhelmed to have much conviction in his desire to protest.
"What's the matter, Deku?" He asked, releasing his mouth so he could speak.
Deku dropped his gaze, shielding his tears behind his bangs to try and hide. "I'm scared, Kacchan. Humans have always been so mean and racist to me. They've always done everything they could to be cruel and make my life miserable. I could never be able to live with it if you did something to get me in trouble."
Katsuki hated that it could have been a very real possibility if he was any other human. The fear and insecurities that humans have given this harmless vampire was not anything light. He also was willing to bet that Deku's Mother must have questioned his judgment about being friends with a human, if how awkward and tense he got about the subject was anything to go by. It really must have been quite the disaster of a talk he'd had with his Mom about Katsuki. It must have put even more doubt in Deku's head; his mother's skeptical questioning and the suffocating air whenever he crossed paths with Inko Midoriya.
It wasn't as if the woman was mean to Katsuki though, and though she didn't seem to trust him and probably forbid Izuku from trusting him like that, she was otherwise very kind to him.
But still she had that power over Deku's thoughts, and had probably made his insecurities worse, even as unintentionally and as good heartedly as it was. She should have trusted his judgment instead of making him question himself. Because Katsuki couldn't think of a time where he even insinuated that he would ever do anything behind their family's back, and deep down, Deku had to realize that.
"Hey," He called gently to the now freely crying vampire in his lap, he grabbed his chin between his finger and encouraged him to look up, "come on, look at me."
Deku did, eyes big and soft, broken and begging.
Katsuki shattered.
"I won't hurt you," Funny how it should be Deku saying that to him in these circumstances, but the fact that it was Katsuki telling him only solidified the suspicion that Deku has never been shown kindness and he was starved in more ways than one. The blonde felt a genuine need to correct it on behalf of his race, making it his life's mission to show Deku basic human decency. "I've always trusted you not to hurt me, now I want you to trust me the same way. I would never even think about betraying you. You're gonna end up starving to death and I just want to help."
"Ka-Kacchan, I'm fine, you don't have to feel obligated-."
"It's not an obligation. I don't want to eat breakfast, lunch, and dinner every day with those stupid substitute bags in your hands. If nobody else in the world will keep you from going hungry then let me feed you." His grip on his chin tightened and he could feel the fingers over his shoulders shaking.
Feeling bold, Katsuki put his free hand in Deku's hair and gently pulled him in until his freckled face was in his throat, there was minimal resistance but Katsuki could feel the vampire's resolve slipping.
"Please, Deku, just feed."
He feels as the greenette took a slow and long, deep breath. It was at that moment the air shifted and he knew, he knew, that Deku finally broke. His hands both went down from green hair to the hips hovering over his legs, firm and too thin under his fingertips.
"I promise it won't hurt, okay?" Deku said defeatedly, "And I won't take too much."
"I know, I trust you."
Deku licked a long stripe up the side of Katsuki's jugular and the older's hands instinctively tightened, the feel of that wet tongue was unexpected and strange. He didn't think Deku needed to do that, but he did anyway, and now Katsuki was hoping that those hips wouldn't settle down completely on his groin or it would be too easy to tell how much that had affected him.
He was forgetting that this was Deku, and the vampire could very well hear how his pulse sped up and felt as his body became warm under his tongue, his blood rushing faster in his veins. The scent of his arousal present before he had even infected him with his venom. He smirked against Katsuki's flesh, finding the perfect spot with his tongue. The spot where the human spasmed the most under his grip.
The moment Izuku peirces the skin just on the side of the pulse thrumming excitedly in his throat, Katsuki inhaled a sharp but barely audible breath and his eyes rolled back.
Deku knew he would never be able to resist Katsuki for so long again. With just one lick of his tongue, he'd had a taste now, and he would never be able to go back to only feeding on the stupid omega substitute. Or any substitute for that matter. Ever. Because Katsuki tasted like the best parts of Hell and the dirtiest parts of Heaven all in just one little lap of his tongue against the tiny bite.
He sinks in deeper, no more beating around the bush. Deku wanted more.
"Shit," The moan Katsuki let out just then was completely involuntary and pathetically aroused, but in his defense he's never been able to keep quiet when feeling good. Masterbating has always been something he only did well into the night because he was never able to keep the noises he made in check, no matter how hard he bit his lip or covered his mouth.
This arousal wasn't even the same as when he touched himself, because even with no hand on his cock, it was no easier to keep his mouth shut as Deku hummed into his neck. A gentle suckling made his vision blurry, "oh... oh fuck..."
He wasn't prepared for how powerful the aphrodisiac would be. It burned pleasantly through him and circled in his lower half and he immediately considered if maybe letting Deku straddle his lap was... the best... idea.
He's hard. He's hot. He's sweating. He's panting for breath and he's so fucking hard and he doesn't know what to do other than grip Deku's hips harder and pull him closer. Plant him directly on his groin and press.
Deku let out a growl, low and deep. Animalistic. And fuck, if the vampire did that again then this was going to get embarrassing for Katsuki fast.
Izuku's hand came up to blonde hair to grip at the strands and pull it to the side to expose more of his throat. Not too hard, but just firm enough to cause the human to whine and roll his hips up. Katsuki felt trapped, but not in a bad way. He was a willing participant and it was a deliciously inescapable hold that the vampire had on him. Deku moved his hips away, and the action physically hurt as he had nothing to rut against anymore.
Katsuki couldn't deny it anymore, couldn't try to hide from it; this made him burn so hot. He liked that Deku had so much power over him, so much damn control. Even if the blonde changed his mind and wanted to stop this, he wouldn't be able to. And if Deku suddenly decided that he wanted to be cruel and rough, he could. If he decided he wanted to drink every last drop, Katsuki would not be able to get away or do anything to stop him. Katsuki would have to just sit there and give Deku everything he chose to take. He put his life in the vampires hands, and it was so fucking hot that he could chose to end it at any moment.
And Katsuki would not be able to escape.
Despite all of that, he's never felt so sure of his safety in his life.
He trusts Izuku.
Izuku is good.
"Fuck, Deku, please," he begged, not above grinding up into Deku like a slut. He didn't know the aphrodisiac would be this strong, but he understood now why people got so addicted to it, why they paid so much for it, why they would do anything for it; because it was so fucking good and Katsuki felt like he was drowning. Sinking down into oblivion never to be seen coherent again. "Oh... mmmh. Yesyesyes, please."
Katsuki was pushed down on his back, a thrill shooting down his spine at the firm shove even as teeth never left his throat. Deku seemed to be giving in to his cravings and Katsuki couldn't be happier at the fact, a strangled whimper leaving his lips before a much louder cry of pleasure broke free as a knee snuck between his legs and pressed down into him.
The human gasped, wanting this to last forever, but then Deku stopped.
Katsuki was left panting for breath as that sinful tongue licked the wound clean and sealed it up for him. Leaving behind no evidence of what he'd done.
What a weird feeling, Katsuki thought, feeling the skin on his neck knit back together.
It didn't stop the heavy tingle of lust still running through his body, and neither did the hand running gently through his platinum blonde hair. All he wanted to do was move closer to the warmth of the vampire over him, closer to the smell that lured him in, taste the prettiness of his skin.
Fuck, he was slipping.
They were quiet for a few minutes, allowing the venom to dissipate, and for the air to fill the human's lungs at a normal level. After a moment Katsuki started to relax, and his heart rate started to go back to a normal rhythm. Only then did the blond swallow thickly and speak.
"You're eyes are green." He commented almost dreamily, staring up at the emerald color inches from his face. The soft gaze watching Katsuki for any signs of distress or illness, but Deku wouldn't find any because the human has never felt so warm, so safe, so excited. "Fucking beautiful."
Freckled cheeks blushed deeply, but his expression didn't change otherwise.
"Feel better?" Katsuki asked.
Deku nodded, "I don't think I've ever felt this good." And he hadn't, the vampire had never been given the opportunity to feed to his heart content, let alone on something so healthy for him. Silly how the government expected him not to go rogue when they made it so hard to live on the blood substitutes. That shit should be given for way cheaper than it is.
"Well, get used to it. 'Cause I'm going to come by and feed you every day now." Though a lot of the venom had cleared already, a great deal still lingered and Katsuki couldn't fight the temptation to touch Deku's face, so he did.
The touch on his chin startled the vampire, but he didn't pull away. "Kacchan, you really don't have to do that. I can't ask you to-."
"I know you can't ask. Not yet anyway, but we'll work on that. I just can't sleep at night anymore knowing how hungry you are."
Deku gave him a long look, his thoughts going unvoiced and yet Katsuki felt like the nerd was analyzing him so meticulously that it felt like if he twitched the wrong way, then Deku would be able to tell what he ate for dinner at this exact time 5 years ago. It was odd, knowing someone was reading him so hard, not many people bothered in the past.
"Would you ever befriend and feed another vampire? Are you just that type of person, Kacchan?"
Shit. He really could just see right fucking through him, couldn't he?
"No. I'm not," Katsuki said carefully, because he wasn't that type of person. The idea of being a blood source for any random vampire, friend or not, didn't sound like something he would volunteer to do. He couldn't imagine making such an offer for anyone else. "Just you, Deku."
"Why?" The word was broken halfway through on a crack in Deku's throat, and while he hated seeing the nerd sad, the way his green eyes glistened was so fucking pretty he felt himself soften. The reality of what he was doing for Deku hitting him hard. He knew how much this must mean to the nerd.
"I'm not too sure, honestly." Katsuki said as he stared at eyes he had never seen before. He didn't think they could look anymore like jewels but the glittering of his tears made them even shinier. He watched as a tear fell, leaving a trail over a freckled cheek down towards his pink lips. Pretty. Soft. Pink. Wet.
They tasted like caramel.
A deep shudder rocked through his body, and while he didn't know if it was him or Deku that had moved, he had zero intention of backing away. Katsuki kisses him, hands coming up to cup Deku's cheeks before raking backwards over his ears till green hair was between his fingers. Soft, just like the lip he sucked into his mouth and licked.
Deku was shivering over him, his body stiff and his hands pressing into the bed on either side of Katsuki's shoulders, unsure what to do. Until a light nip on his bottom lip made him melt, and he opened up for the blonde and hummed in approval when a wet tongue licked the roof of his mouth. It tickled, the flesh there sensitive. Every brush and swipe made him tremble as he slowly dropped his weight onto the human below him. He pressed in closer, fully between Katsuki's legs now and he licked the underside of the tongue in his mouth.
Dazed and confused, Izuku swallowed down every moan the human couldn't hold back, the sensations overwhelming and stimulated by the venom in his veins.
This was Deku. The way Deku smelt. The weird way Deku tasted like caramel even though he just fed. The sheer strength of Deku as he pressed Katsuki down into the mattress and kissed him back. The boldness of Deku's features from the darkness of his lashes to the cuteness of his freckles and the gorgeous green that showed through when his eyes cracked open to look at him before shutting again to kiss Katsuki deeper.
It was Deku.
DekuDekuDeku.
Katsuki felt like he was falling and floating and hitting the ground over and over all at once and he never wanted to move from this spot. He was breathless, he was excited, he was sleepy, he was happy, his heart was pounding and it felt like his blood was boiling to the point he thought it was supposed to hurt but it didn't and instead was so pleasant.
It was blissful. Never ending.
Katsuki felt skyhigh yet grounded and it was the most profound feeling that he has ever had and he was suddenly scared. So scared. Because he didn't want to ever know how painful it will be if this went away. He had no idea he could be this vulnerable, but now that he knew, the idea terrified him because as much as he tried and tried and tried to be strong...
He was weak.
He was bare.
Open.
Deku pulled back, smirking a bit as Katsuki tried to follow his lips. He stopped the blonde by hooking his thumb on the corner of his mouth. The human whined at the loss of his lips but started sucking the vampires thumb.
"Calm down, Kacchan, my venom is strong." Heated green eyes thoroughly watched red ones. The beautiful crimson marked with small specks of black here and there, pretty like a rose and darkened with the need for sex.
Drool dripped down Katsuki's chin and if he pushed his hips up just a little, he could feel how hard the vampire was. It was intoxicating, but enough venom had cleared for him to know it was time to calm down. Fuck that shit was intense though! The kiss had helped quell the urge to hump, and rut, and grind as a means to an end, but his pants were still too tight with the evidence that it wasn't nearly enough to satisfy him completely. It would have even been considered painful if the pain wasn't so damn sweet.
Shit.
It took a few minutes for him to calm down a bit more, his heart working to pump fresh blood that wasn't infected with venom. When he could finally look at kiss swollen lips and resist the temptation to try and catch them with his, he breathed and gathered his thoughts. He needed to focus, and remember the point he was trying to make.
Right! The situation at hand.
Crap. What was that again?
Oh yeah.
"Tell me when you need to feed. Okay, Deku? I'll feed you. I don't want you to have to be in so much pain anymore." He said, trying to sound as serious as he could with a damn hard on that refused to go down.
"I can find a way to pay you back, Kacchan."
"I don't want your money."
There was a heavy pause, a quiet one.
"Then..." the vampire gulped, "If you do want, I can... um." His hand tentatively trailed down Katsuki's bare chest towards the lump in his pants until he started playing with the button on his jeans, about to undo them. "I can take care of you this time and then next time I'll let you... you know. Do what you want?"
Sex.
Deku just offered to let Katsuki fuck him for blood.
Katsuki stopped the vampire's hand with a grip on his wrist, pulling his hand back up to interlock their fingers together. Deku's hand was so much bigger than his and as much as he fucking craved his touch down there, Katsuki just...
He couldn't let him do it, "No."
They will want s-sex. I-I-I can't agree to have sex with someone when I'm not in love with them.
"You don't have to do that either." Katsuki grabbed his other hand and laced their fingers together. Both hands now in his grasp on either side of his head, supporting the vampires weight which was still above him. It was nice; the closeness. "I don't need you to repay me like that either, Deku."
"Then... What is it you want, Kacchan?"
"Just keep letting me hang out with your nerdy ass. I like being able to come over whenever the fuck I want."
"Kacchan! That sounds so lame compared to what you just let me do." The vampire frowned, and this was one of the cute ones that made Katsuki want to tease him over.
"Trust me Deku, I get a lot more out of it than you think."
Deku smirked seductively then, and the action was so random that Katsuki almost didn't know what to do so instead he just allowed his legs to tremble. "Get a lot out of what? hanging out with me, or from me feeding off you?"
"I-" Katsuki had never been one to stutter, especially not from embarrassment. Fear maybe, but never just from a pretty face looking at him like that.
Suddenly it hit him what they had just gotten through doing, he had just made out with Deku while trying to grind against him like a slutty dog. The thing about that was Deku was unaffected by his own venom, he was not being driven out of his mind by lust. Katsuki had just attacked his lips with sex crazed desire and Deku let him.
They were... friends...
Katsuki's deep blush could have cooked an egg if the vampire cracked one on his face.
Deku leaned down until he was an inch away from his ear, hot breath fanning at it and causeing goosebumps to rise in the area that the vampire had been latched onto just a few minutes before. Katsuki felt his pants tighten up again just from that, and he was distinctly aware of what he got himself into by letting the vampire hover over him with their hands laced together, holding him down. Did he subconsciously do this to himself? Maybe.
Suddenly it occurred to him that Deku was still between his legs and if he shifted just a little bit upward-
Still thinking with his dick, huh? Got it.
"Kacchan, my venom is nearly completely faded from your system but you're still hard as a rock against my knee." Said knee pressed a little harder into Katsuki, the pressure on his poor neglect cock forcing a gasp out of the human's mouth. "You really get off on being beneath me, don't you? I bet you think a lot about how I could rip your throat open if I really wanted, huh?"
Fuck.
Deku's voice was like a purr close to his ear and Katsuki involuntarily tipped his head back, giving in, because again, he was weak to this. Izuku was expressing obvious interest now, and though it hadn't been the first time, this was the first time that Katsuki couldn't brush it off his shoulder as playful teasing. He couldn't play this off as his own hopeless imagination.
Deku was not being subtle anymore and the change was almost scary.
"You're like putty in my hands right now, Kacchan," A wet tongue licked hotly along the curve of his ear and Katsuki shivered, "Is it because you believe with your whole heart that I would never hurt you?" That tongue went down to his neck, licking a trail from his ear to the sensitive parts on his throat where he sucked lightly with his lips, kissing over his pulse. "Is it because you feel safe?"
"Yes," the human breathed, his voice coming out hoarse and unable to be held back as fangs raked against the large vein in his neck without breaking the skin. So close, they could rip into him at any time and Katsuki could do nothing about it. Red eyes flickered closed as he started happily losing himself in the vampires touch all over again.
"Good." Deku smirked as hips tried to shift upward for some kind of friction against the straining dick in his jeans, he shifted away in turn, not allowing the human to find the contact that he craved. The sound he made at the denial was as pitiful as it was hot and Deku pursed his lips at the blonde in amazement. The poor baby must be so pent up.
"I need to feed you," Deku said, "And you need to take some iron to recover what I took. So I'm gonna go make you a sandwhich and you're going to stay right here on my bed like a good boy and take care of that." He nodded his head down towards Katsuki's lower half, eye demanding and leaving no room for disobedience. "Lubes in the drawer."
Fire licked down Katsuki's neck and then down his spine straight to his dick, and he knew that once Deku was gone, he wouldn't be able to last long even if he tried. This was going to be over before the vampire even made it to the stairs. Katsuki shut his eyes, his impending humiliation inevitable as Deku got up.
The human stayed put, not even bothering to move as Deku headed towards his door.
"Oh, and Kacchan?" He looked over his shoulder to the blonde who already looked wrecked despite the fact he hadn't even touched himself yet. His voice salacious. "Please remember for me that I can hear everything."
...
Wow wee wow.
Well. Tell me what you think
Tell me how you feel
