Katsuki was growling before he even made it all the way up to his room, the sound of his mother's voice still ringing in his ear. She was yelling at him for not coming home the night before, but he must have been doing that several times a week since last time she pitched a fit, so to be honest he was surprised that she hadn't noticed before. Normally her fits were spread out more and the duration of peace between each one was a bit longer, but apparently Katsuki has been particularly annoying to her for it to have only been a month.

Just as he closed his door he could hear her stomping up the steps, and with every loud thump that got closer, he could feel his chest tighten like someone was synching rope around his ribs. Apparently what he thought had been the end of the conversation was only a brief reprieve until the next wave of her desire to fight with him escalated.

When she barged in, he had to take a step back or risk letting the door hit him right in the face. He knew that she was coming, but damn it almost seemed like she was hoping it would hit him. His hands flew up to protect himself from a collision that otherwise would have been painful, "Geez could you fucking knock?"

"I want to know where you disappeared to," Her voice carried, and he was sure if he was on the other end of the house, he would still be able to hear her yelling at him. "If you don't tell me, Katsuki, so help me," She left the end of her sentence open, the threat existent despite not being articulated.

"I was at Kirishima's!" He hollered back, just as his father was coming up behind his wife.

"Katsuki, please refrain from yelling at your Mother, it's not nice," Masaru said, coming in and trying to mediate the situation. He was the only one not yelling, holding his hands up facing the floor in front of him as it that would somehow get the two blondes to chill out.

Spoiler alert: It didn't work.

"Fuck that, who fucking cares where I was, anyway? It's not even a school night so what reason do you have to be so goddamn nosey?" He hated that they were doing this in his room. His safe space. The only part of the house where he can find some peace.

Well, besides the bathroom, maybe.

"So if I call Kirishima right now, he'll tell me that you were at his place all night?" She asked with skepticism laced between all her words, venom dripping from her teeth despite the fact she was part of the human portion of society.

How ironic was it that her venom was more dangerous than Deku's?

"Yes! Now can you please get out and leave me alone?" Katsuki grabbed his door and motioned that he wanted to close it again, but Mitsuki was pulling out her phone. The conversation not over until she was ready for it to be over. Just like always. She paused as she scrolled through her contacts, looking up at him in suspicion.

"Give me yours right now. No funny business mister, I know how the buddy system works," she said holding out her hand as she held her own phone up to her ear.

He rolled his eyes, "You never gave it back after last time, Hag."

She stared at him for a second, a stupid look on her face before it reddened in embarrassment and she put her outreached hand back on her hip, "Bet you think you're real smart right about no- Oh, hello, Kirishima! I have a quick question, I hope you weren't busy."

Kirishima said something on the other line, and Katsuki just hoped that the younger teens brain cells weren't all burnt up from the last time he got his hair done.

"No problem, I just needed to ask you where my Katsuki was last night." Katsuki held his breath, but maintained his poker face. "Mhmm... All night, huh? Are you sure?"

Masaru was looking between the two blondes cautiously, his presence was a comfort in the sense that Katsuki could at least rest assured his mother wouldn't hit him, but the man was otherwise useless.

"I see, okay. Thank you, Kirishima. Have a good night." She glared at her son as she hung up without even waiting for a response from the redhead, seemingly disappointed that she was wrong and she had no real reason to fight.

His story had checked out, and Katsuki decided right then to do Kirishima's homework for a week.

She huffed and poked a finger into his chest, the touch as uncomfortable physically as it was emotionally, "If I ever find out you're going to some slut's house, I'll fucking end your whole life before you get a chance to start it, you hear?"

Katsuki wordlessly nodded because he just wanted her to leave. He didn't even care to argue, and he wouldn't dare consider telling her he had no interest in women, let alone pussy.

Bleh.

She turned and left, shoving passed Masaru as she did so.

Shoulders remaining tense, Katsuki looked over to his father after his mother left out of sight. The man looked like he didn't know what to do anymore, stuck there standing awkwardly in place with his hands to his sides. Masaru looked like he wanted to say something but failed to get his words out, and every time he opened his mouth and closed it again the blonde could feel his eyebrows knitting tighter and tighter together.

Katsuki sighed and pursed his lips, giving the fuck up.

Disappointed and wanting nothing more than to be alone right now, he looked at his father and spat, "Just get the fuck out."

Masaru gave him a pained look, but still said nothing. With a nod of his head, the man slipped out and left.

Finally, the teenager was able to shut his door loudly and click the lock.

Fuck!

He put his forehead on the door and released a breath, his chest still as tight as it was when Mitsuki barged in. He put a hand up over his heart, feeling stupid for being so afraid as it beat rapid and harsh against his palm. He was on the verge of one of his damn anxiety attacks but he was just grateful that she had finally left him alone.

Katsuki exhaled a shaky breath, trying to calm his heartbeat, squinting his eyes shut. He was suddenly dizzy, the back of his neck burned hotly, his cheeks felt numb, and the tingling of his toes was evidence of his body telling him he was in danger. He took a deep breath and willed his erratic heart and his wobbly knees to realize this was no longer the case. Sweat was dripping down his face and he knew if he looked in the mirror right now he wouldn't have as much color in his face as he normally does.

Fuck all this shit.

He thumped his head against the door, not loud enough to alert his parents who he could hear arguing with each other in their bedroom, but hard enough to cause a tiny bit of consequential pain to blossom in the spot. He opened his eyes slightly, deciding he didn't have the energy to stand anymore.

Katsuki pushed himself from the door to walk over and collapse dramatically onto his bed. His ears were ringing and his back felt cold but his body was too heavy for him to give much of a shit anyway.

A few minutes later, after not feeling any better and the uncomfortable tingling in his legs hadn't dissipated, he heard a light tapping on his window. It was light, barely there, and if his window wasn't directly adjacent to his bed, he was sure that he wouldn't have heard it at all.

Katsuki lifted his head off the pillow curiously and shuffled over to his window. He knew who it was before he even made it all the way over.

"Deku!" He whisper shouted, though secretly he was happy to see the vampire. He hadn't been planning on going over, figuring his Mother would probably check in on him now to make sure he didn't leave, so Deku coming over himself was a relief. "The fuck are you doing, shitty nerd?"

"Um... Repunzel, Repunzel, let down your hair?" Katsuki was not amused by his shitty attempt of a joke no matter how wide his lips spread, but he did unlatch his window with a roll of his eye.

"Seriously, Deku. I swear to fuck if you only came here because of the shitty fight I just had, you and I are throwing hands," Even as he was saying so, he grabbed the vampire's hand and helped pull him in quietly.

"Ahhhhuuuh," Deku said awkwardly, looking anywhere but at Katsuki.

"Deku," Annoyance and anger made his voice come out a suspicious growl.

"Oh, come on, Kacchan!" He exclaimed quietly, not even bothering to try and make up an excuse for himself, "Even if I did come here just because of the fight, what's the matter with that? I'm your friend, and that's what friends are supposed to do." The vampire defended with a shrug in his shoulders.

"It matters because I don't need you in here just to look down at me with those stupidly large eyes if yours pitying me like I'm some kind of abused child." Red eyes narrowed at dark green ones, said 'stupidly large eyes' only getting bigger as he spoke.

"I'm not pitying you!" Though, Deku kept it to himself that he was starting to feel like that's exactly what Katsuki was. The vampire had no idea what life was like for the blonde before the last three years, but evidence was blaring at him that it couldn't have been any better than it was now. "I promise! Kacchan, I would never look down on you. I couldn't; You're leagues above me."

Katsuki skeptically made a noise with his teeth, "Yeah, the fuck, right."

"It's true, Kacchan!" There he goes with those big dumb eyes. Those deep, green, shiny, beautiful eyes. "You're amazing! You work so hard. With school, and work, and home. Managing to find time to take care of yourself with exercise, and then to even tutor your friend on his homework as often as you do." Deku really needed to stop talking, "You're incredible. I've always thought so. Please believe me, I would never even think about pitying you, Kacchan."

Katsuki released a slow breath, his shoulders sagging involuntarily. He didn't get why he believed Deku so easily. If someone like Kirishima had said any of that stuff he would have immediately decked him in the face and kicked him out of his house.

This was Deku, though, and Deku was different, "So, what are you doing here then?"

"Well, Kacchan, just because I don't pity you doesn't mean I can't come over and keep you company." He didn't mention he specifically came over because Katsuki's heart rate had risen to a scary level, and he had been worried the blonde's anxiety attack could possibly get worse. Deku knew Katsuki pretty well, so he was willing to bet that the blonde would happily ride his attack out alone in his bedroom and then never mention it to anyone. As much as Deku would praise Katsuki all day if he could, the human had a stupid habit of not telling people when he was having a hard time. "Please, let me stay. I miss you anyway."

After a small pause, Katsuki decides to give his annoyance a rest. He refused to admit that his previous fear was almost nonexistent now that his friend was here, but he did admit that he was too tired to keep his mask of indifference up. What was the point? Deku knew he was upset, there was no hiding that. Not from him.

"Fine, but if the Hag leaves her bedroom then you have to dip, because she doesn't knock." Deku gave him a smile and a light seemed to glimmer in his eye as he nodded.

Stupid ass fucking nerd acting all happy and shit.

Katsuki sighs and turns towards his radio, deciding he would put on some tunes and leave Deku waiting while he did his bedtime routine. It was after 10, and while normally he waited to sleep until 11 with his new work schedule, he was exhausted. Knowing he would be too drained to do it later, he washed his face and brushed his teeth so he wouldn't have to worry about it before he finally decides to crash for the night.

Deku was on his bed when he came back, his calm grin lighting up his face as he took in Katsuki's room. Though the blonde didn't think there was much to look at; the whole place was neat and he had just gotten through doing his laundry when his Mother came home and called him downstairs for their 1 hour argument that eventually lead up to his bedroom. Everything was put away and the only posters he had were the small Hero Allmight ones that he had been able to get with birthday money over the years. The bookshelf was neat and alphabetical, and the only lamp in the room was plain black and white. Nothing special.

"Sorry, there's not much to do here but read and listen to music. I'm not in the mood to be super conversational either, so don't expect any cutsie gossip about boys or pillow fights in our pajamas." Opening up his dresser drawer, Katsuki pulled out a pair of sleep pants and a tank top. He could feel eyes on him as he lifted his shirt over his head and bent over to take off his jeans, but the blonde didn't mention it.

Let Deku get a load of his ass in his boxers, what the fuck ever.

And no, he did not undress slower than normal.

Not a damn bit.

Fully dressed, Katsuki joined Deku on his bed. The nerd was already laying down, resting his head up on a propped arm with a sweet smile on his face as the human got comfy.

"It's okay if you don't want to talk," Deku was saying as he moved, "I just like to be close."

"Stalker."

The vampire giggled, "Oh, Kacchan."

Shit, his pillow felt so good under his head, fuck.

Katsuki shut his eyes for a moment, taking a deep breath. Normally his attacks lasted 10-30 minutes and then he even had after effects to deal with. Like nausea, agitation, or just not feeling anything at all for the rest of the day only to wake up the next morning with a migraine.

Right now was a completely different story though, and it was stupid how much better he felt after a few short minutes. He no longer felt like the floor was caving in below him while a tight rope was the only thing keeping him from falling.

Maybe Deku's lure had something to do with it, as subtle as it was. Even if it was soft in his senses, Katsuki could still smell that gentle yet distinctly gravitational aroma. It soothed his nerves, just like a cup of hot coffee on a chilly morning or a hot bath after a long day of hard labor.

Katsuki was calm.

Still, it was difficult to relax. He hadn't gotten much time to himself outside of using the restroom and sleeping in a long time. Actually he could hardly remember the last time he had gotten much of any time to himself at all. He was always either at school, at work, at Deku's, helping Kirishima with his homework, or home spending obligatory time with his Mom or Dad.

Worse than that, it had become impossible to get off lately. The past few weeks were filled with ruined or unrealized orgasms and at this point he was losing his mind. Even literal aphrodisiac riddled venom had failed the blonde, leaving him pent up and strung with nerves and a hissy mood. Normally he's able to do it a couple times a week and even more now that he was feeding Deku, but lately his poor attempts were so disappointing that he started giving up altogether when he couldn't even get himself hard. He often felt fidgety, like he couldn't hold still, and his restless leg syndrome had been bothering him at night. Tension built up in his shoulders and he was starting to think he was going to have live with this headache until he died.

...

Katsuki must have passed out at some point. He didn't remember when, but he woke up startled. Eyes shooting opened as he realized he had fallen asleep.

He was being stared at.

Deku quickly looked away, embarrassed at being caught watching him sleep. The vampire buried his face in Katsuki's extra pillow with a deep blush of shame.

"The fuck are you looking at, Deku?"

"Sorry, Kacchan," he mumbled, his voice muffled by the pillow, "You're just really pretty."

Katsuki tries to hide his little blush by shielding himself behind his bangs, but he's not sure if he's successful and that annoys him a bit. Deku's flirting lately has become random and deliberate, always catching the human off guard and unable to hide in time. Cocky bastard.

The blonde would never tell him that he loved that shit though, he ate it up like it was his last goddamn meal, "Shut the fuck up, nerd. How long was I asleep?"

Deku smirks, but it was then that Katsuki noticed that his eyes were deeper, darkening with hunger. "About 10 minutes, I was going to get up and turn out the light but you woke up."

It abruptly occurred to Katsuki that it's been a few days since he'd fed the vampire. Katsuki threw his head back and cursed because, shit, he hadn't meant to neglect him. "I didn't come over," he stated almost dumbly.

Deku didn't understand what he meant at first, as his eyes lit up in amusement. To him it must have seemed like the blonde was tired and maybe deliriously stating the obvious in his sleepy state, "Yeah, Kacchan, that's why I did instead."

"Did you run out of O-v2, nerd?"

Deku's eyes snapped open in realization, the softness regrettably leaving his face as shame entered it. The air became a bit tense as Deku started overthinking so obviously that his thoughts could have been audible. He seemed embarrassed too, "Don't worry about that, Kacchan."

"You did, didn't you," Katsuki accused, annoyed beyond belief that he would have to have this conversation with the shitty nerd again. "Why didn't you tell me, stupid Deku? I haven't been over to your place in days!"

This was partly his fault, he knew Deku was still not to the point where he could just ask Katsuki to feed him. He didn't have enough self respect, not enough confidence, not enough comfort. Asking was something he thought was too much for their relationship to handle, like Katsuki would grow offended by it or something. As if being fed was a privilege that he needed to earn no matter how many times he had told him none of that shit is true.

And it was that look on Deku's face- that look of deep self-loathing and shame that bothered Katsuki the most. Because it always meant that he had failed once again to get the vampire to see himself differently than before. Deku needed time, Katsuki reminded himself. Deku couldn't just unwind the tight knot of anxiety and fear he had grown accustomed to using for self-protection all by himself, Katsuki needed to help him untangle it. Patiently.

"Deku, what's that look for?" He could guess the answer already, but making the nerd say it out loud would hopefully someday make him realize how stupid he sounded.

"I feel bad because now you're gonna feel worried and think that you need to help but it's really not your problem and you're already exhausted-."

Never mind.

"Don't," Katsuki cut him off, he was too tired to hear the rest tonight, "Don't talk like that, nerd. I don't do shit that I don't want to do."

Deku hummed, lifting his head up from the pillow to once again prop it up on his elbow. "Maybe not but you're also a good person in general and hate the fact that I have to go hungry sometimes. It's bad enough that I let you feed me on a normal basis at all, but now I'm starting to feel a bit spoiled because you taste so good and when you feed me I always feel so much better, but it feels like I'm taking advantage of your kindness if I let you do it just because you found out I was irresponsible with my supplement and-."

"Deku, you're muttering."

Deku shrinks under the knowing gaze and the soft way the blonde called him out. He stopped talking immediately, as if somehow he realized that there was no point in speaking anymore. His jaw snapped shut with an audible clock of his teeth and his green eyes looked away as he pouted cutely.

Katsuki smirked, but even his slight amusement couldn't help the growing frustration in hitting the same road block as before. He sighed, the blonde just had to keep being patient with the vampire. "You're too fucking timid. Just ask me next time, Deku."

When he spoke, the vampire became still and looked at the blonde again, watching Katsuki's eyes as his lips moved. The red irises held a fondness in them even though he voice spoke of pure annoyance, put together and this was what Katsuki looked like when he was concerned.

Sweet. Sincere. Hard to read, but once you do, it's clearer than fresh water on glass. The veil of harshness was paper thin over the clear care that he often tried to pretend didn't exist around others.

Deku hummed sheepishly, pursing his lips at the unneeded attention. Unneeded, but not unwanted.

"You're hungry, right?" Katsuki asked, but Deku's eyes were already slowly fading to red, so of course he was. The blonde wouldn't believe him if he tried to say that he wasn't, not after he just found out that he's been without nourishment for days now. Katsuki has been too tired and busy to come over in a couple days, instead just going home and collapsing on his bed after doing his part of the chores for the day.

Clearly that had affected Deku. Katsuki had hoped that he at least had the packages to feed him, but apparently the stupid idiot had ran out without telling him. If he would have just said something then he wouldn't be starving right now, but of course, Deku is as Deku will always be; someone who puts himself last.

The vampire nodded, his eyes turning glassy for some reason, like the admission would somehow get him in trouble. As if he was still worried that Katsuki would ever turn his back on him or reject him given the opportunity. The wetness in Deku's eyes didn't fall, but seeing it there tugged at his heart stronger than any lure he'd ever been subjected to.

Katsuki reached a hand up and put it on Deku's face, getting him to look at the blonde properly. His hands were tender and forgiving, incredibly different from his outward personality, "I know I've been kinda busy lately, but I'll always make time for you, Deku. I'm not saying I'm gonna always be at your beck and call, but I'm not going to get pissed off if you remind me that you haven't eaten. Just quit being so fucking humble and text me."

Deku nodded, but the blonde wasn't sure if he actually accepted that he was worth the time of Katsuki's day. Still, it was time to guide him a bit further, Deku was one who needed a bit of a push sometimes.

"Ask me, Deku."

Deku hadn't pulled away from his touch yet, and their eyes were still making contact, so Katsuki was able to see the uncertainty cross his face like a shadow. Was that going too far? Telling him to ask aloud? He could tell the idiots anxiety was something that he struggled with, especially when it came to topics about his species -or worse; feeding. He didn't think asking him to go out on a limb after everything-

"Please?" The whisper came out of nowhere, but Katsuki didn't move a muscle, "Kacchan, please, can I?"

A proud smile lifted the blonde's cheeks, and he brushed his thumb over a constellation of freckles on soft skin. "Yes, Deku."

The vampire was still unsure of himself, but that was okay. It wasn't like he expected Deku to be confident about all this overnight. Not after everything he's been through. Progress was made, exposure was starting to work, and Katsuki was happy. Pulling the younger a bit closer, Katsuki put his head back on his pillow and shut his eyes as he was way too tired to do this sitting up.

Deku gave him a grateful nuzzle on his chest before going up to his throat and kissing over his pulse. As Katsuki hugged around his shoulders and relaxed as the vampire routinely sniffed and licked for a few minutes before he finally bit down, quicker than normal. Poor thing must have been really hungry.

Katsuki released a deep and hot breath, the venom already making it hard to avoid getting a hard-on.

Holding Deku this closely, with his arms holding onto him around his shoulders, he could feel how the greenette's body had changed in the time that he's been feeding him. He's grown a lot bigger, his arms were thicker than before and his back muscles bulged under his hands, soft and firm. Katsuki could tell that the amount of weight he had put on had all gone to the right spots of his body and he was now lean and strong. Clearly Deku would look really good without a shirt on.

Fuck.

There goes any chances Katsuki had in not embarrassing himself. He was hard as a rock and the blonde could feel the moment that his dick lifted to life and all but jabbed Deku in the thigh. He could feel a wet tongue on his neck and gentle sucking that should have been painful but instead made his toes curl and his hips shift involuntarily.

His eyes rolled back and his mouth opened, but before he could make a sound Deku put a hand over his mouth to keep him quiet. That didn't stop the moans all together, in fact it only made him hotter, but it did muffle them as they caught in the vampire's palm.

Katsuki knew already that Deku never let him grind up against him when they did this, but that didn't stop his body from reflexively trying. His hips jolted, and his fingertips dug into Deku's back, but like always the stupid nerd avoided pressing their hips together. The blonde would curse him out if he didn't understand why the vampire did it.

Can't get addicted to this. Can't let it lead to sex when they aren't ready. Human's can't consent mid-feeding. It's considered assault yada yada.

Breathing hard didn't help Katsuki stay quiet, and he was glad that Deku knew what to do because he was sure that he would have alerted his parents by now and that would have been a no go. He massaged Deku's shoulders, purely just to feel the muscles there, his hot skin burning below the fabric of his shirt.

Everything was too hot. He had too many clothes on. Deku had too many clothes on. Katsuki wanted to let his hands wonder naked skin and touch him everywhere. He wanted to know if his nipples were as pretty as his lips, if his ass felt as good as it looked under those pants, if his freckles decorated anywhere else on his body.

Fuck, but most of all he wanted to be touched. Deku's hands felt so good on his body, and he was consciously aware of every movement they made. One was covering his mouth and the other was gently holding his left wrist to the bed, petting the inside of his palm with his thumb. He imagined them holding his hands roughly above his head, firmly holding his hips in place, gripping the back of his thighs as he held them up on either side of his head as that tongue-.

Two fingers prodded at his lips and Deku lifted from his neck mid feeding, his voice deep and husky like they were actually in the middle of sex, "Quiet."

Katsuki opened his lips obediently and immediately those fingers filled his mouth, long and warm and surprisingly thick. He hadn't realized that his noises were getting louder. Katsuki licked over them as they started pulling out and pushing in slow until drool started to escaped the corner of his lips. The wetness glistened in the light and put Katsuki deeper into his haze of lust, imagining the other things he vampire could do with those fingers.

Deku went back to feeding, licking up the trail of blood that had escaped in his absence. Nothing would go to waste.

The fingers kept his noises under better control. If he got too loud, then Deku would gently push further into his mouth to encourage silence. He kept the slow pace of fingering his lips, pushing in and pulling out. Katsuki's hands drifted down to the hem of Deku's shirt, playing with it between his fingers and he lost himself in the vampire's ministrations. His chin was wet with drool and spit but he hadn't made a sound too loud since Deku started doing it, and Katsuki didn't want to. He wanted to be good.

The moment Katsuki's fingers dipped under the hem and touched bare skin, Deku decided he had finished feeding and pulled back a bit to lick the wound closed. He picked his head up and watched the blonde for a moment, listening to the small whine that the human made at the loss.

Deku licked his own lips, shoving his fingers in Katsuki's mouth a little deeper with a smug look on his face before pulling them out completely. They were wet and shiny and the blonde's eyes were dark and hooded, breath hot and uneven as Deku put them in his own mouth and sucked. The look on the vampire's face made something hot twist in Katsuki's gut before fluttering up towards his chest like a flock of birds startled by a sudden noise. The feeling was so strong and so warm that his eyes became dizzy. Screw the nerd for being both unbelievably pretty and the sexiest being to ever fucking exist.

Katsuki all but stopped breathing as he watched Deku slowly pull his fingers out of his mouth, and he didn't know how the vampire expected him not to try and grind up helplessly into his hips. Of course, Deku shifted away from his attempt. This was actually torture. Fucking bastard just liked to tease him at this point.

A tiny relieved moan vibrated in his throat when 2 seconds later Deku was kissing him.

Katsuki's hands flew to green hair, gripping it, playing with it, raking his nails in it's softness while Deku's hands cradled his sides. The human was once again hit with the deep want to rip all of their clothes off. Skin on skin contact sounded so good right now as Katsuki once again shifted his hips upward to try and grind against the thick bulge in Deku's pants. Another failed attempt as Deku lifted a knee up to press on his thigh, holding him firmly in place. The action was so fucking hot but not at all helpful in getting the blonde off.

Then as if to further put Katsuki deeper into his misery, Deku grabbed his wrists from green hair and pressed them above his head in one solid fist, using the weight of his body to make it impossible to escape as the other one pinched his chin between two fingers.

Katsuki felt the full weight of the fact that Deku had to be doing this on purpose; there was no other explanation. Izuku had to know just how much this affected him. If not from the uncontrollable moans he made that were muffled by the damn tongue in his mouth then from past experiences when his only reaction to being dominated was to rut hopelessly into anything that his hips could reach.

Deku's tongue became too distracting to be mad though as he did something in Katsuki's mouth that had him completely forgetting about his dick for a second. Venom was still potent in his veins, so everything the vampire did made him hot and want to beg for more, but his mouth was too busy being devoured for him to plead. Dark spots of lust sparkled behind Katsuki's shut eyes as his tongue was sucked and played with, and oh how he wished that Deku would just let him do something to relieve the pressure building in his lower half. His dick was so hard it was honestly starting to hurt. He was so pent up. So needy. So full of heat. He wanted to touch himself so bad, but the grip on his wrists kept him from moving. He wanted to cum. Really, really, wanted to.

It was incredibly sad when the vampire pulled away from his lips with a wet smack, so sad that Katsuki leaned up to chase him, to reattach their lips together, but he had zero luck getting that to happen too.

"You haven't touched yourself in a while, Kacchan," Deku said just a breath away from his kiss swollen lips, the blonde could feel his breath fanning across his chin as he spoke as if reading his mind.

Given the opportunity to come to his senses a bit, Katsuki was able to look up at him clearly. The venom still affected him and made it hard to think past the desire to flip them over and have his way with the nerd, but he resisted the temptation.

Not that he would physically be able to do that.

No, Deku was a strong boy.

His dick twitched.

Yeah... If Deku wanted Katsuki under him, then under him is where Katsuki was going to be.

Which was not helping put his erection down.

The human huffed as he found a few brain cells and put them to good use to speak, "Tch. Don't act like you didn't hear how my last attempts have gone, you stalker." He hated how his voice came out; a whole octave higher than normal and sounding completely wrecked, giving away just how tightly wound and deprived he felt.

Deku hummed low in his throat, though he didn't give an immediate verbal response as he stared down at Katsuki with an unreadable look in his eyes. He was still held firmly in place by the vampire's hand above his head, but it was more affectionate now than it was before as he rubbed the pad of his thumb against the inside of the humans wrist, tracing the vein there. It was so distracting that his mind started to turn to mud, which was why when Deku did speak, Katsuki choked, "Can I do it?"

The human's eyes widened as every brain cell he had worked so hard to zap to life, abruptly fizzled completely out of existence. He stared at Deku blankly for a moment as he replayed his words over in his head, making sure there was no other meaning they could possibly hold. But there was only one thing Deku could be talking about, and the sudden clarity of the suggestion had him narrowing his eyes in doubt.

"Deku," he growled low and poisonous, "We already talked about this shit before, you don't have to do stuff like that just to repay me."

Deku was quick to amend himself, his voice quiet enough not to be heard outside the room but still defensively louder than before, "It's not to repay you!" He shook his head, eyes wide in return for the dubious glare Katsuki had at his request. "I just know how pent up you are, Kacchan. If you're willing to let me, I want to help. Come on, please?"

Katsuki kept his eyes narrowed but one brow lifted as he saw no reason to believe that Deku was lying. It wasn't as if the idea of Deku jerking him off was disgusting, quite the opposite actually as his dick twitched to attention at the idea of those hands wrapped around it. It was just strange that asking to touch cock was so much easier for him to do when he had such a hard time asking to be fed.

"Is this supposed to be some kind of friends with benefits proposal?" Katsuki asked. And, okay, maybe he might be interested.

The edges of Deku's lips curled upward as he rolled his eyes, "You don't have to say yes, Kacchan. I just wanted you know I'm willing if you'll let me."

"Aren't you worried your venom is inhibiting my ability to consent? You're always so firm about not letting me give in to dry humping you like an animal in heat." No matter how hard he tried, no matter how painful it got, Deku had never gone further than heavily making out with him. His hands were always above the belt and they never wondered to places that Katsuki's body begged him to go. It was both infuriating and relieving that he could trust Deku to take good care of him and still not step over any boundaries their relationship wasn't prepared to cross.

Deku frowned, "I would never touch you if I thought that was the case, Kacchan. Never." He shook his head, "I can smell how much venom is in your veins, and there's not much left. You're perfectly capable of saying no, or I would never have offered. You've got to know that."

Katsuki did know that, with unwavering confidence and not even a hint of doubt or qualm.

He trusted Deku, because Deku is good.

Deku released Katsuki's wrists, and the blonde brought them down to his sides. The vampire was still hovering halfway over him, but he was free to move if he wanted. He looked Izuku up and down, trying to understand, "You're not just doing it as some shitty form of payment?"

Shaking his head, Deku's voice dipped smoothly, "No, Kacchan."

"Then how come you wanna touch my cock so bad?"

Deku blushed at his vulgarity and bit his bottom lip, deep in thought. Then his gaze became hooded, the look on his face eager with desire and ardor, "I like the noises you make when you cum."

Katsuki blushes hard at how undaunted and flirtatious the statement was as his eyebrows rose. His dick twitched in his pants again and he wondered if his erection would become a permanent state of being.

"I wanna know what your face looks like," Deku's continued as his thumb came up to rub against his cheek, and the human knew how red and hot it must be under the vampire's touch. Deku's straightforwardness made the blonde's eyes widen comically large and for a good minute, Katsuki was too stunned to respond. He gulped loud.

When he did though, he was proud to say he kept his voice level, "You know, Deku, for someone who acts all withdrawn and diffident all the time, you sure are one dirty mother fucker."

The shrug he was given was as playful as it was sly, and the tiny grin lifting freckled cheeks made his expression impish. So different from normal but not at all unappealing, his face was so pretty to look at. What devil did this man strike a deal with to be both cute and hot at the same time?

It wasn't fair.

The hand on his face was suggestive and seductive, gently caressing his lips as Deku's face was only a few inches away. Asking him for permission to touch. There was no glint of uncertainty and no depressive darkness shadowing those emerald orbs, just the provocative shimmer of passion and yearning. As if Deku was so sure of what he wanted, and that was to touch him. To watch him come apart under his hands. To make him cum after so long of not being able to do it himself.

The thought of that hand being wrapped around his cock was so enticing, he could almost imagine what it might feel like. Deku's hands were a mix of being warm and soft but with the strong ability to be rough if he wanted. The visual of cumming all over those hands got a new wave of heat pooling in his lower tummy, making his cock throb and his toes curl.

He wanted Deku to touch him.

Fuck, he wanted that so bad.

He threw his head back and groaned, feeling defeated and desolate as he sighed.

"Not tonight, Deku. I can't risk you getting in the habit of thinking you have to do it just 'cause I fed you." He shut his eyes dejectedly, his tone remorseful with deep regret.

"But, I know I don't have to," Deku insisted with a pout.

"Shh," Katsuki murmured, pulling Deku down so they could go to sleep. "I'm not going to risk what little self-respect you have for yourself, Deku. I believe you when you say that's not why you wanna do it now, but I know for a fact that head of yours is going to start overthinking it in the future."

Deku made a small noise, and if Katsuki didn't know any better he might say it sounded disappointed. He paid it no mind as he turned on his side, thighs close together to hopefully forget about his dick.

Reaching up, he grabbed Deku's hand, lacing their fingers together again and holding them on the pillow between their heads. Deku breathed out and seemed to relax, the tiny grin returning to his face where it belonged. Katsuki studied his features and his sleepy green eyes, his black eyelashes darker than obsidian and bolder than sharpies. If he concentrated, he could remember how those lips had felt on his.

The vampire hummed quietly and shut his eyes, squeezing Katsuki's hand in his, "Your hearts still racing, Kacchan. What could you possibly be thinking about?"

Katsuki tore his eyes away from Deku's mouth and smirked, "Just wondering what you'd look like if I drew a mustache on your face with sharpie."

One eye peaked, petrified, "Kacchan, don't you dare."

The human actually had to cover his mouth or risk his laughter being heard by his parents. It tried to burst out of him at the look on Deku's face, like the younger couldn't tell if he was being serious or not and was afraid to go to sleep now. The sound of his laughter hit Izuku's ears and-

Oh.

The sound was like a siren beckoning him to hand over his soul for consumption, and at that moment it felt like that's exactly what Katsuki had done.

Reached inside him, took something important out, and swallowed it whole.

Deku didn't even think that it would be missed.

He didn't even try to fight it. It would have been a useless battle. There was no armor he could have put on, no wall he could have built, no tower high enough and no moat deep enough.

Nothing could have protected him from it. Nothing could have been done to prepare or prevent it.

In an instant, Katsuki had taken all his power.

In an instant, Deku was weak.

Eventually, he nervously laughed along with the blonde, his chest feeling light and warm as he watched the smile reach Katsuki's eyes, making them light up like ruby under starlight or fireworks going off for the first time. He hoped that Katsuki wouldn't be able to tell how much of himself he had just involuntarily given, because oh, dear... he had just given way too much. Even worse, he didn't even want any of it back.

When Katsuki's laughing fit turned into a tired yawn, he buried his face into the pillow. "Don't worry, nerd, your face will still be normal by morning. I'm going to sleep."

Deku grinned fondly, the smile packed with more than words could ever express, "Okay, Kacchan. Good night."

But Katsuki was asleep already.
