Be My Slave, Deku chapter 1 to 4 from Smutsuki_Bakuhoe on Archive of Our Own beta

This was it. The time had come.

Izuku's one chance to right the ultimate wrong.

He had to save Kacchan. Save him from himself.

He'd known the explosive blonde since they were toddlers. They'd been best friends until Izuku's Quirkless diagnosis, at which point they'd drifted apart and become little more than bully and victim.

But despite all that, Izuku had never stopped looking up to Kacchan. He was amazing after all. He was incredibly smart, had an amazing Quirk, and an unending drive to be the number one hero.

Then, Izuku met All Might, the Sludge Villain incident happened, and everything started to change.

Izuku got into UA using this newfound power, but it made Kacchan angry. The blonde got worse and worse, culminating in his being chained up during the Sports Festival victory ceremony, thrashing around like a wild animal and trying to explode his way out of the restraints.

That led to the summer training camp. The disastrous night when Kacchan had been taken by the League of Villains, kidnapped so that he would join them.

Izuku had been unable to do anything but laugh at the idea. The thought of Kacchan giving up on his dream of being the number one hero? Of becoming a villain? It was ridiculous.

Or so he'd thought.

The heroes made a valiant but ultimately unsuccessful attempt to rescue Kacchan, and then they were in the wind. They disappeared for months after that, no one knowing where they were or what they were doing to Kacchan.

It had been the most stressful months of Izuku's life up to that point.

And then the League reappeared, in the middle of a massive explosion that rocked part of downtown Tokyo. An explosion caused by none other than Katsuki Bakugou, sneering at the cameras and flipping off civilians as they begged for mercy.

The unthinkable had happened. Kacchan had joined the League of Villains, and seemingly of his own free will.

The following few years had been chaos. Izuku and Kacchan had met in battle multiple times, neither one coming out the clear victor. Izuku tried to reason with him every time, but it seemed to fall on deaf ears.

But that was all about to end. They'd managed to capture a few members of the League and had extracted intel about the location of their hideout. Now was the start of an operation that would hopefully capture the entire League, including Kacchan, in one fell swoop.

And once he was safely behind bars, they could start the long process of trying to bring him back to his senses.

First they had to succeed though.

"All teams, move in." Izuku heard over his earpiece.

He was tasked with making a solo infiltration to the heart of the compound and trying to subdue Kacchan as quickly as possible using the specialized Quirk-cancelling cuffs he'd been provided.

He heard the sounds of the assault teams attacking the main entryways of the compound and made his move, leaping down from the tall tree he'd been hiding in since morning and moving towards the side entrance to the underground compound they'd discovered during surveillance.

He let One For All flood over his limbs and smashed his way through the reinforced steel doors like they were paper. That was when things went sideways.

The moment he landed in the hallway, he felt something sharp prick into his neck and immediately started to feel woozy.

"Thought you got the drop on me, didn't you, stupid Deku?" He heard Kacchan's sneering voice and barely managed to turn himself to face the source.

He saw Kacchan standing there in his full villain costume, which was pretty much just his old hero costume, but with more spikes.

"K-Kacchan…" he was finding it increasingly difficult to keep on his feet, or even to keep his eyes open. Whatever he was stuck with was working fast through his system.

"Tch. Don't worry, Deku. We're gonna take really good care of you." Kacchan gave his confident little smirk (that Izuku had always been kind of attracted to) before turning and addressing someone off to the side. "Alright, collect him, gently. Don't wanna hurt the little nerd...yet. Then we gotta go before those stupid heroes realize we're onto them."

He felt arms grabbing at him to restrain him and tried to fight, but whatever sedative was working through his system was already doing its job. He had no strength to fight back and before he could process anything else, his vision faded completely to black.

When he came to, Izuku had no idea how much time had passed, or for that matter where he was.

The concrete room seemed mostly barren from what he could see. He was currently suspended by his wrists from the ceiling and had his legs chained to the floor as well, such that his body was splayed out in an 'X' shape. The bindings on his wrists seemed to include Quirk-cancelling abilities, since he found he was completely unable to call upon One For All.

All of his costume and equipment had been removed except for his green jumpsuit. Even his red sneakers he wore under his Iron Soles were gone, leaving him barefoot.

The room itself had only a cheap looking cot tucked into one corner and a toilet in the other. There was no door he could see, but he seemed to be suspended in the middle of the room and there were some things behind him but he couldn't turn his head well enough to make any of it out.

Suddenly there was the loud scraping of metal as a door somewhere behind him was pushed open. "Finally awake, huh Deku? Took you long enough."

"Kacchan? What's going on? Where did you take me?"

"Shut up, Deku. Doesn't matter where I took you, cause you're never leaving here again, Mr. Number One Hero." He said the last bit with obvious derision and a scoff, finally stepping around into view, no longer in his villain outfit, instead in comfortable black slacks and a fitted, red button down that showed off his well defined pecs and broad shoulders.

"Kacchan, please. You don't have to do this, this isn't you. We grew up together, we used to be friends, you wanted to be the Number One Hero!"

Kacchan simply laughed, short and dismissive. "What a joke that turned out to be. I'm much happier like this anyway. Besides, now it's gotten me the thing I really want most."

Izuku tilted his head in confusion. "What?"

Kacchan smiled a wide, evil grin. "You, Deku. You're mine now, and I'm gonna keep you all to myself." He emphasized his point by rubbing a hand sensually over Izuku's chest in his jumpsuit.

Izuku, despite himself, felt a blush rising in his cheeks. "W-what are you talking about Kacchan?"

The blonde sighed in annoyance. "Guess I have to spell it out for you, huh Deku? I've claimed you as my own. You're going to be my slave, to love me and serve me in any way I choose." He pushed forward, his body pressing against Izuku's and his hand reaching around to squeeze Izuku's supple, round ass. Izuku could feel Kacchan's firm erection pressing up against his leg.

He tried to squirm away, but was helpless to go anywhere with the firm chains binding him in place, suspended from the ceiling. "Kacchan, that's ridiculous! I'm not gonna be...y-your slave!"

The blonde chuckled and stepped around behind Izuku again. He could hear the sounds of Kacchan sorting through some things on a table, but he still couldn't get a good look.

"Yeah, I figured you wouldn't just agree immediately. That's ok. I've got a whole plan to train you and make you submit to me." He sensed movement and then suddenly Kacchan's mouth was right up against his ear as he spoke with a soft, dark, and sinful voice. "And you will submit to me, Deku. It's just a matter of time."

Izuku felt a shiver go down his spine and he couldn't stop himself from gulping anxiously. Kacchan let the moment hang in the air a few seconds before speaking again.

"Now, I don't really feel like hearing you complain during the first part of your training, so put this on, Deku." He reached his hands around and held up a small red ball gag in front of Izuku's mouth.

He held his jaw firmly shut tight. No way was he gonna let Kacchan put that in his mouth.

"You'll quickly find life is much easier when you simply listen to me, Deku." He let out a sigh when Izuku still refused to open his mouth. "Fine. Let's see if you're still as ticklish here as you used to be."

Kacchan moved one hand down to a particular spot on the side of his hips, where Izuku had always been extremely ticklish. Kacchan used to tickle him there when they were children, and he still knew exactly how to work that spot.

Izuku couldn't contain himself, he burst out in giggles and laughs, which unfortunately caused his mouth to open wide enough for Kacchan to quickly shove the ball gag in his mouth and secure it tightly behind his head. Izuku whimpered and whined in protest, but was helpless to do anything about it.

"There, that's better. Now we can start the real fun. Though, you won't be needing this anymore, I just wanted the pleasure of taking it off of you myself."

Kacchan reached his hands around and grabbed his jumpsuit in both hands, then let out small explosions with his Quirk, pulling and tearing the suit asunder until Izuku was wearing nothing but his underwear. Izuku whined in protest, and squirmed to try to cover himself, but it was pointless.

"Won't need this anymore either. In fact, you're never wearing clothes again, Deku. My slaves don't need clothes." Another grab, explosion, and tear and Izuku was now hanging from the ceiling naked as the day he was born.

"Beautiful." Kacchan sensually ran his hands over Izuku's newly exposed flesh. Caressing both globes of his ass, up his back, down his chest and stomach, and ever so gently cupping his cock and balls. "You know, I was always attracted to you, Deku. I always wanted you to be mine, but you wouldn't drop your stupid dream of being a hero, despite being a Quirkless loser. Now, though, we're going to fix all that. We're going to right this relationship, make it how it should've been in the first place." He leaned in close to his ear again, speaking in that sultry deep voice. "Are you ready to start?"

Another shiver ran down Izuku's spine and he shook his head no, but Kacchan totally ignored him. He walked around in front of Izuku again, holding in his hand two black clamps of some kind. "Let's begin with something simple. You have such amazing nipples, Deku, let's see how sensitive they are."

He brought the clamps up towards Izuku's chest. He tried to twist away, but he had very little room to maneuver. Kacchan forcefully grabbed his face with one hand to steady him and stared straight at him, burning red eyes locked with fearful green ones. "Hold. Still. Deku."

Much to his shock, Izuku's body obeyed. Not out of some mind control or Quirk or anything, but simply from the sheer force of will behind Kacchan's command.

The clamps were brought up to Izuku's nipples and secured into place. They squeezed uncomfortably at the buds, which were fully erect due to his exposed state in the slightly cold stone room.

The clamps had weight to them, more than you would think based on their size. There must be something inside the little black cylinders hanging from each one.

Kacchan stepped back and simply admired Izuku's squirming form for a moment before pulling a remote of some kind out of his back pocket. "Trust me Deku, you're gonna enjoy this." He smirked as he pressed a button on the remote and suddenly both clamps started to vibrate, sending all kinds of intense sensations coursing through his nipples to the rest of his body. The sensation was overwhelming at first, forcing him to screw his eyes shut, but eventually he couldn't stop little moans and whimpers from sneaking out around the gag.

As humiliating and awful as this was, the sensation didn't feel bad at all. In fact, it felt pretty good. He immediately regretted closing his eyes when Kacchan reached out and grabbed onto his cock, slowly stroking it with a lubed up hand.

"Mmmph!" Izuku moaned and whined, unable to stop the blood from rushing into his cock at the stimulation to both his nipples and his cock. It rose to its full length, such as it was, in seconds.

"You know, Deku, I must say I'm rather disappointed. The Number One Hero apparently doesn't have the Number One Cock. Number three cock maybe, for the number of inches it is." Kacchan chuckled to himself as he continued to stroke Izuku's unimpressive length with agonizing slowness. The greenette felt his cheeks flush with redness and embarrassment. He knew he didn't have a particularly large cock, but he'd never really been sexually active before so it had never come up.

"Oh well, not like you were gonna get much use out of it anyway, so it doesn't really matter how small and pathetic it is, right Deku?" Kacchan looked at Izuku expectantly, but Izuku merely stared back, trying not to let out any moans.

Kacchan's face suddenly screwed up in anger and he grabbed onto Izuku's balls and squeezed hard. "I said... right Deku? " Izuku cried out in pain around the gag, tears streaming down his face and he nodded in agreement just to get Kacchan to stop.

"Good boy." Kacchan said as he released his grip and returned to his slow, sensual stroking of Izuku's cock. He leaned forward and licked the tears from Izuku's cheeks. "Oh this is gonna be so much fun. Ready for the next step, Deku?"

Izuku looked into Kacchan's eyes, begging him with his gaze to stop this. Please, Kacchan. Remember how things used to be. You don't have to do this .

Kacchan merely smiled. "Good. Let's get to it." He stepped around behind Izuku, the nipple clamps still buzzing away and Izuku's cock still sticking out painfully hard and leaking precum.

Suddenly, his world went dark as he felt some kind of blindfold being secured around his eyes. Kacchan's sultry whisper was right in his ear again, the tingling sensation heightened by his inability to see. "It's even better when you can't see what's coming."

He heard the sound behind him of something slick being applied to someone or something, he couldn't tell. A moment later, he felt a warm hand squeezing at his round ass. "Mmm Deku. You're cock may not be very impressive, but this ass. This ass is going to be so much fun to play with. Let's see how well it adapts, huh?"

With no further warning, Izuku tensed and screamed around the gag as he felt a slick, lubed finger pressing insistently against his tight virgin asshole, trying to gain entry.

"Trying to fight me, huh? How many times do I have to tell you, this will be so much easier if you just relax and give in, Deku?" He heard the click of a button on Kacchan's remote and suddenly the intensity of the vibrations on his nipple clamps kicked into high gear, causing Izuku to moan loudly around the gag and forcing his body to relax, letting Kacchan's finger slip inside his hole.

He let out a sound caught somewhere between a moan and a cry of pain as the slicked digit slid deep into his ass. "That's better. Now just relax and this'll start to feel real good soon, Deku."

Kacchan steadily started working his finger in and out of Izuku's tight hole, and he seemed to be moving around inside, like he was searching for something. After a few moments, his finger pressed on his prostate and Izuku's eyes rolled into the back of his head as he moaned hard around the gag.

After a few moments, he heard Kacchan laughing. "Wow, you came already! Just from that? You're gonna be the perfect little slut for me, Deku, I can already tell."

Izuku was mortified. Did he really cum just from some vibrating niplle clamps and Kacchan fingering him? He could feel the last drops of cum leaking out of his cock and knew it was true.

It was so embarrassing. But at least it was over now.

"You think that's it? You came so I'm all done?" Kacchan asked, as if reading Izuku's mind. "We're not done, Deku. Not by a long shot."

He emphasized his point by pressing another button on his remote, causing the nipple clamp to vibrate even more intensely and by shoving a second finger inside of Izuku's hole. With his free hand, he reached around and started slowly jerking Izuku's now extremely sensitive cock.

Izuku thrashed and moaned and whined, trying to beg Kacchan to stop, but the gag was still firmly in place, drool leaking out around it and muffling all of his words into nonsense. He could feel fresh tears of overstimulation falling down his cheeks.

"That's right Deku. Feel it. Feel every moment of this pleasure. This is what I can do for you. This is how good I can make you feel if you choose to submit to me." He slipped in a third finger, really starting to stretch out Izuku's tight ass.

Surprising himself most of all, Izuku's cock slowly returned to its full hardness, all three inches of it, rock hard and twitching as Kacchan slowly pumped up and down, never for a second picking up speed, all the while his other hand was working three fingers into his ass, twisting and spreading them, occasionally pressing against his prostate in a way that made his entire body shudder.

He hated every second of this, but most of all he hated how good it felt. How his body betrayed him. Every corner of his mind was screaming for this to stop, that it was wrong. This was Kacchan, his childhood best friend, turned villainous nemesis. He shouldn't be enjoying this sexual torture.

But he was. Or his body was anyway. But it felt like only a matter of time until his body overrode what his mind wanted and demanded more.

"I think that's stretched enough. Or at least as stretched as I have the patience for. I've waited long enough for this prize, it's time I took it."

Izuku felt Kacchan's hand leave his cock and his fingers slide out of his asshole. He despised the way his body seemed to feel empty at their absence. He was thoroughly disgusted with himself, and couldn't imagine how it could get any worse.

At least he couldn't imagine it until he heard the tell tale sound of a belt being undone and a zipper being pulled down.

Sensing what was coming, Izuku started to wriggle and squirm, desperately trying to get free.

SMACK

He cried out around the ball gag as he felt Kacchan's hand sharply crack against his bare ass.

SMACK! SMACK!

Two more hits, punctuated by a low growling sound from the villain behind him who he'd once called friend.

"One day soon, Deku, you're gonna learn that obeying me and submitting to me is easier than fighting me. And if you think some ball squeezing and a few spankings is the worst I can do to you, think again fucker. Now sit still and accept what's coming."

Izuku slumped down, knowing that there was nothing he could do to stop it. Kacchan was going to fuck him.

He could only pray that the blonde was on the smaller side like he was, but he somehow knew that wasn't the case.

He didn't have to wonder long, as he heard the sound of lube slicking up Kacchan's now freed cock and felt his hand applying a fresh layer to Izuku's hole. A moment later, he felt the blonde's left hand gripping his hip tightly as the other guided his cock head right up against Izuku's tight hole.

He heard Kacchan let out a slow, rasping breath of anticipation. "Been waiting for this for a long time, Deku. Try to enjoy it, but either way, I'm gonna have my fun."

With that, he felt the cock head start to press against Izuku's slightly loosened asshole. Unfortunately, no amount of stretching and prepping would make it easy for him, a virgin, to take the clearly massive cock that was pushing its way into him now.

He'd practically screamed himself hoarse already from the prior sexual torture, so the sounds that eeked out around the ball gag were little more than pathetic whimpers of pain as Izuku felt his hole split open around Kacchan's apparently humongous cock.

"Mmmph."

"Yeah, that's it, Deku. Moan and whine for me. One inch down, only seven more to go."

Seven more? There was no way. Izuku already felt like there was half a foot of cock inside him, how was this only an inch? And it felt like an entire soda can worth of thickness. The pain was excruciating, but he continued to be helpless against any of it.

Kacchan continued to taunt him as he steadily pressed more and more of his cock inside Izuku's stretching hole. "Look at you, Deku. With your magically appearing Quirk suppressed by these cuffs, you're the same Quirkless loser you always were. A pathetic Deku, useful only for taking my cock."

Izuku could only whimper pathetically, but in the state he was in, he couldn't really disagree with anything Kacchan was saying. Right now, he was little better than that Quirkless loser he'd been as a kid. Honestly, he was even worse than that Quirkless loser, because at least that version of him hadn't ever been chained up and raped by their former best friend.

Kacchan slid another inch inside, causing the head of his massive cock to press firmly against Izuku's prostate. He desperately tried not to react. To will his body to ignore the sensation. But he couldn't.

The moan that slid out around the gag was sinful and his cock was painfully hard and twitching pathetically between his legs, begging for attention.

"That's it. That's a good Deku. See? It can feel so good when you let it. It's just a matter of time before you're my slave. If you embrace it sooner, then it can feel this good all the time. Better even." He pushed in again, harder this time, and Izuku could feel his hole stretch to its limit around the thick shaft, but he could also feel the incredible sensation of that same shaft sliding along his prostate, sending waves of pleasure through his body.

"You're almost there Deku. Just one more inch left." Izuku shook his head. Sure his body was feeling the pleasure, but his ass felt so full. There was no way he could handle any more of this. It would break him.

"Come now, Deku, don't be like that. You can do it. You just gotta go Plus…" he paused there as he shoved the last inch in, bottoming out in Deku's no longer virgin ass, "Ultra. Ah you feel so fucking good squeezing around my cock, Deku. You're making your Kacchan very happy."

Despite the pain and discomfort coursing through his body, he couldn't stop the wave of satisfaction at hearing those words, and that disgusted him more than anything. He'd always wanted to make Kacchan happy, to make Kacchan proud of him, but not like this. Not at all like this.

"You've done so well taking my cock like a good little slut, Deku. Time for a reward." Kacchan reached around in front of him and started to jerk Izuku's tiny cock once again, but this time he wasn't using the slow languid pace from before, he was really jerking it.

Izuku was overwhelmed by the stimulation. Kacchan was jerking his cock with abandon, the clamps were still vibrating away on his nipples, and Kacchan's huge cock was still pressing firm against his prostate. Izuku was helpless to do anything but moan and writhe, lost to the pleasure.

In no time at all, it peaked as he orgasmed yet again. This time he could feel it hit him full force and could feel the meager load shooting out of him and onto the floor.

"There you go, Deku. See how good slaves get rewarded? Now keep being a good boy for your Kacchan, while he wrecks your tight little hole."

Izuku's eyes widened behind his blindfold. Kacchan wasn't going to stop. He was going to keep going, even after Izuku had already cum twice now.

True to his word, Kacchan began to slide his length out and push it back in. He started slowly at first, but he quickly threw all caution aside and started pounding into Izuku's hole without mercy. Every thrust was slamming into his prostate and his body was completely overwhelmed with the sensation.

He began to lose all sense of reality and the passage of time. All he could focus on was staying conscious as Kacchan fucked into him with such force you'd think he was the one who had One For All, not Izuku.

It was hard to tell, since he was still blindfolded and it was so hard to focus on the various sensations all running through him, but he was pretty sure he orgasmed a third time during all that, though he doubted much cum came out. He really couldn't take anymore of this. He truly felt like this whole situation might kill him.

He suddenly felt Kacchan's mouth up near his ear again. "You want it to stop, Deku?" He was practically growling in Izuku's ear.

Izuku nodded his head pathetically, unable to answer out loud.

"Then you'll have to beg me for my cum. I could keep going for hours, Deku, but if you want me to stop, then you'll need to beg me for it. Beg for me to cum in that tight little ass of yours, Deku." He reached up and undid the strap on the ball gag, allowing Izuku to spit it from his mouth onto the ground.

His jaw ached from having been held open for so long and his throat was sore from all the moaning and screaming and whimpering he'd been doing.

"Come on, Deku. If you want it to stop, you know what to do." Kacchan leaned back and redoubled his efforts of pounding his cock into Izuku's fucked out hole.

Izuku had no choice. He really couldn't take any more. "P-please. Please, Kacchan." His voice was barely more than a whisper.

"Hah? What was that? I couldn't hear you, Deku. You'll have to talk louder than that."

"Please, Kacchan! Please! Make it stop!" He raised his voice as loud as he could.

"That's better, I can hear you at least. But that's not what I said. That's not what you need to say to end this…" Izuku was still blindfolded, but he knew the evil little smirk that was most definitely on the blonde's face right now.

"Please, Kacchan. Give me your cum. Cum inside me Kacchan." He said it as deadpan as he could. He'd play along, but he wasn't going to give the bastard the full satisfaction.

"Hmm. I think you can do better, but I suppose it'll have to do for now. I was gonna cum soon anyway." He laughed near-maniacally as he slammed his hips hard against Izuku's plump ass over and over until his laughs turned to grunts of animalistic pleasure.

He buried his cock as deep inside of Izuku as it would go, and Izuku could feel the warm fluid flooding his insides. Rope after rope of cum. It felt almost inhuman how much there was.

Eventually, the orgasm subsided and Kacchan slid his cock from Izuku's now wrecked hole. He could hear some of Kacchan's cum sliding out and hitting the floor.

"Tch. Gonna have to teach you not to waste my loads, Deku." He smacked Izuku hard on the ass and it sounded like he knelt down to...scoop the cum off the floor? Suddenly he got his answer as three finger shoved the cum back up inside of Izuku's ass.

"Ah! Kacchan, please, that's enough! I can't take anymore!"

"Shut up, stupid Deku! You'll take what I tell you to take. You're the one who can't keep my load inside like a good boy. Gonna have to teach you that eventually. For now, we'll just have to plug you up."

The fingers slid out of Izuku's hole, but were almost immediately replaced by a hard rubber object that seemed to get wider the further in it went. "Ah, Kacchan! Stop! Please, stop! It hurts!"

"You'll be fine Deku. Learn to keep my cum in you like a good slave and you won't need this plug." Eventually the thickness tapered off and now it seemed to be firmly secured inside his ass, pressing right up against his prostate.

"There. Now, you did alright for your first training exercise, but not great. I'd say a B- at best. Guess that means we go straight into the next step in your training."

"What? No, Kacchan! I can–mmph" the rest of his words were cut off as the ball gag was shoved back into his mouth and secured behind his head.

"You can and you will, Deku. This is just your reality now. Get used to it." Izuku heard a button press and the vibrating nipple clamps mercifully switched off, but Kacchan didn't remove them.

He flinched as he felt Kacchan's hands securing some kind of plastic object around the base of his cock. The hell was that?

"Alright, you're all set, Deku. Gonna just leave you like this for a while. Try to stay conscious if you can, you'll enjoy it more that way. But either way, this should start the process of breaking your body and eventually your mind down to my will."

He heard another button press on the remote and suddenly his whole world was spinning. All three devices, the thing attached to his cock, the nipple clamps, and the anal plug, all started to vibrate at overwhelming intensities. The plug was still pressed right up against his prostate, and when combined with the heavy vibrations against his cock, he had a fourth orgasm immediately. He could feel the pathetically small amount of cum leaking out from his dick, but still the vibrations didn't let up.

Katsuki chuckled as his voice moved away towards the door. "Have fun, Deku! I'll come check on you in a few hours or so."

And with a thud of metal on stone, the door closed and Kacchan was gone. Izuku was still chained and suspended from the ceiling. His Quirk was still suppressed. And these devices were still vibrating away against all his most sensitive spots.

He could feel his mind start swimming, delirious from the overstimulation. Despite that, he could already feel another orgasm coming on. This one came and went as quickly as the last, but there was no cum left in him to shoot. He was firing dry now, but on some level it still felt good. He was humiliated and disgusted with himself, but he was most disgusted by the fact that he didn't entirely hate it.

Izuku came to who knows how many hours later as the devices shut off. He must've passed out at some point, but he had no idea when.

"Shhh, it's okay Deku. It's over now. You did so good." He felt the blindfold finally being removed and blinked the brightness away to see Kacchan in front of him. He was freshly showered and changed into nothing but casual sweatpants and a black tank top. "Your Kacchan is so proud of you." He felt Kacchan gently caress his cheek and he was too delirious to stop himself from smiling at the praise and the gentle touch.

The chains were undone (though the wrist cuffs that cancelled his Quirk were left firmly in place) and Izuku collapsed into Kacchan, unable to hold up his own body weight.

"Hey hey hey. There ya go. It's okay, I've got you, Deku. Kacchan's got you. You did so good today, I bet you're exhausted. Let's get you in bed, huh?"

Izuku merely nodded. This was such a different Kacchan than the one who'd been abusing his body just a few hours earlier. It reminded Izuku of the Kacchan he always dreamed the blonde boy would grow up to become. The one he'd often fantasized marrying one day, when he was younger and more naive.

Kacchan gently carried him to the cot over in the corner and laid him down onto it. It wasn't the comfiest bed in the world by any means, but Izuku didn't really care. After how exhausted he was from the "training" it was practically heaven.

He struggled to keep his eyes open, but he felt the blonde use a wet washcloth to gently clean away the sweat and cum from Izuku's body. "One last thing, Deku." Kacchan's voice was so gentle and caring now. It made Izuku smile in a way he just couldn't help. "You still have a lot of training left to go, and I can't have you cumming without permission, so we're just gonna lock you up, okay?"

Izuku was barely conscious at this point, and Kacchan was being so kind and gentle right now. Izuku could hardly be blamed for just nodding along in absent-minded agreement. A moment later, a small green plastic cage was securely locked around his small cock, ensuring he wouldn't be able to touch it at all.

Kacchan gently wiped the hair away from Izuku's eyes and smiled down at him. "There ya go. Nice and secure. Now you just roll over, get comfy, and get some sleep. We'll start again in the morning."

Izuku nodded and rolled over, mumbling out a "Good night, Kacchan."

"Good night, Deku."

As Katsuki rose from the bed and headed towards Deku's cell door, he couldn't stop the evil smile that spread across his face. Deku was making this too easy, but he still couldn't help but be excited for what was yet to come.

When Izuku awoke, he was alone in his cell. He had no idea how much time had passed, since there were no windows and nothing to give away the passage of time.

All of the "equipment" Kacchan had been using had been cleared out, so the only thing left in the room was the cot he was sleeping on and the toilet in the corner. He shifted to stand which was when he finally remembered that he was naked.

The cot didn't have any sheets or blankets, but the room was kept at a comfortable temperature, so he wasn't very cold. He did stare down with a frown for a little while at the little plastic cage that was still firmly secured around his cock.

As much as he wished he could say that everything that had happened the day before was a blur in his head, the truth was he remembered every excruciating detail (save the chunk of time he'd passed out for). He remembered the shame and humiliation, the pain of being fingered and then fucked by Kacchan's massive dick. He remembered being forced to beg for Kacchan to cum inside him. And he remembered being left alone, hanging from the ceiling, with vibrating devices on the most sensitive parts of his body, forcing him to orgasm over and over again.

The shame and humiliation was honestly easy to remember, because he was feeling it now just thinking about it all. He felt sick to his stomach, compounded further by the fact that he could feel his cock straining inside the cage to get hard. Why the fuck was his body getting aroused by this? What was going on with him?

He needed to get out of here. But how?

Trying to willfully ignore his nudity, he got up and did a thorough sweep of his cell. The cot was bolted into the cement floor, not enough that he couldn't rip it out easily with One For All, but the Quirk-cancelling cuffs were still tightly around his wrists, and nothing he could do would remove them.

The only exit to the room was a thick locked metal door, set into a reinforced frame. Nothing shy of heavy explosive or a powerful Quirk was going to make that thing budge. It did have a little sliding door set at about head height and another at the base, but both were too thick to be considered weak points, and far too small for him to fit through even if he could open them.

His options were pretty limited. He had no Quirk and nothing he could use as a weapon, not even clothing, since they weren't providing him with any. He was extensively trained in various forms of close-quarters combat, so he didn't really need a Quirk or a weapon to take on most opponents.

However, his chances of success in brute forcing his way out of this room was dependent entirely on who it was that came through the door. He had trouble going head-to-head with Kacchan even with a Quirk, so fighting him without one would be near impossible. He'd have better luck if some goon or lackey came in, but even that would depend entirely on what sort of Quirk they had.

His best option may just be the patient one, waiting and enduring until an opportunity presented itself. He shuddered a bit at that thought, however. If what happened yesterday was a sign of what Kacchan yet had in store for him, he wasn't sure how long he could hold out.

He was still in shock that Kacchan would even do something like this in the first place, much less to him. As much as it pained Izuku to admit, Kacchan had done some awful things since turning to villainy, but as far as he knew he'd never done something so awful as to kidnap and sexually torture someone.

And why Izuku? They'd been close as kids and he'd always looked up to Kacchan, even through their darker middle school years, but the explosive blonde had never seemed particularly fond of Izuku all the way up until his abduction at the summer training camp.

Sure, Izuku had always been attracted to Kacchan, first through the eyes of youthful innocence, but as he'd gotten older and puberty had hit, he'd started to gain a physical attraction to the other boy as well. He blushed in the empty room as he realized that he'd in fact fantasize about Kacchan doing things like this to him in the past, albeit with a little less humiliation.

If you're gonna go through it anyway, maybe just try to enjoy it next time.

Izuku shook his head aggressively, his hair flopping about on top of his head as he tried to shake that tiny voice deep in his brain away. He couldn't just give up and let Kacchan do whatever he wanted. He was a Hero, the Number One Hero, and he had pride to maintain. He wasn't going to be a villain's plaything, even if the villain was his unfairly attractive childhood best friend.

As if waiting for these thoughts to start swirling in Izuku's head, the door made a loud *ka-chunk* sound of the lock disengaging and it pushed open to reveal Kacchan stepping into the room, back in his dark slacks and red button down shirt from their "session" the day before.

He really is unfairly handsome.

Izuku gulped, pushing those thoughts down as best he could.

"Good afternoon, Deku. Sleep well? You were out for almost 16 hours."

16 hours? He supposed he was exhausted after everything that happened, but he hadn't slept that long in a number of years.

"You ready for a new day of training, slave?" Kacchan grinned and stepped further into the room, but Izuku stood his ground, attempting to summon all the pride and courage he could, while standing naked with his cock trapped in a plastic green cage.

Kacchan scoffed. "Don't tell me you're gonna try to be defiant, Deku. After how good you were yesterday, I was hoping you might let yourself enjoy this."

He reached his hand out towards Izuku to grab onto him, but the greenette decided in a split second he wasn't going to give in and let this happen. Quick as a flash, he grabbed onto the blonde's arm and moved to twist it harshly around behind his back, attempting to force Kacchan to drop to the ground and subdue him.

Kacchan seemed ready for this maneuver, though, and simply rolled with the twist, landing in a crouch and bringing his hand up, throwing an explosion right into Izuku's face. The blast sent him stumbling back, blinking his eyes shut from the heat and force, leaving him wide open for Kacchan to bring his knee hard into his stomach.

Izuku fell to his knees completely winded and stunned for the moment.

"Damn it, Deku!" Kacchan grabbed him by the throat and slammed him down onto his back, pinning his arms down with his knees and keeping a firm grip around his windpipe, enough to make breathing a struggle, but not quite choking him. "I warned you not to fight me. That I could make things miserable for you if you tried. I was really hoping it wouldn't come to this, but clearly you're not ready to give in and be my slave."

He looked down at Izuku and let out a sigh. For just a moment it looked like he was looking at Izuku with...pity? "K-Kacchan?"

"I didn't want this for you, Izuku. I was hoping we could do it my way, but you're going to be my slave, whether it be the easy way or the hard way. Unfortunately, you've chosen the hard way. Oh well, at least it'll be fun to watch him break you down." Kacchan's mouth once again twitched up into that evil smirk as he glanced up towards the doorway and motioned someone in.

A moment later, two massive hulking goons, probably with some sort of Gorilla mutation Quirks given the excessive hairiness and insane musculature of their bodies, stepped into the room and stood Izuku up, each one having a firm grip on one of Izuku's arms. A black bag was slipped over his head and he was dragged out of his cell and down the hall.

In retrospect, he should've tried to memorize distance traveled and turns made, but in the moment he gave in to fear and panic, trying to squirm and fight his way free of the goons, but it was useless. Without his Quirk, they were exponentially stronger than him. His struggles had no effect on their hold on him.

After several minutes of travel through the halls of whatever hidden villain compound he was being kept at, he felt himself thrown down onto some kind of hard surface that was sticking up from the ground at a 45 degree angle. In the brief gap of time after he'd been tossed onto the surface, he attempted to scramble to get away, but was immediately met with a massive fist straight to his stomach, leaving him totally winded yet again, and helpless to stop the goons from bringing his hands up and securing his wrist cuffs such that his arms were held up above his head. His feet were also bound to the table below him, leaving him bound for a second time in as many days.

The bag was ripped from his head and the two goons left him alone in the room. The floor and ceiling of this room were cement, much like in his cell, but the walls were a much more roughly hewn stone. They almost looked like someone had carved this room out of a cave or something. Glancing around, he saw a number of tables set up around the table he was bound to. A few of the objects on them he recognized as dildos of varying shapes and sizes (he silently prayed that a few them would never be used on him, because they were huge ), and he saw what looked like a few different kinds of collars and restraints, but everything else was totally foreign to him. He saw various rods made of either glass or metal, different metal clamps and devices, a few things that looked like they were paddles of some kind, and several different objects that looked like long leather objects that had been cut into strips at the end.

The "table" he was bound to also looked strangely complex, at least as much of it as he could see. It had a large rectangular block in the middle, which was where his torso was lying, and long pieces that stuck out of the top and bottom, which was where his arms and legs currently rested and were secured.

The different pieces looked almost modular, like they could be moved around independently of each other, and he suspected the table itself had some kind of hydraulic system that would allow a person to adjust the height and angle of it.

Strangely, the thing that set him on edge the most was the lighting. There were strip lights set into the floor all along the edges of the room that were casting an intense red light up onto the walls, giving the entire room an ominous red glow. It was almost infernal, the way the light cast upon the jagged edges of the rough stone walls.

"Oh, hey Midoriya!" Izuku looked up and froze from shock at the person who stepped into the room. Dressed in his full hero costume, a great big goofy grin on his face like always, was Denki Kaminari, Pro Hero Chargebolt and someone he considered a good friend.

"K-Kaminari? What are you doing here? Quick, you've gotta get me down before Kacchan comes back!"

Kaminari made an exaggerated wince for show. "Ooo, sorry buddy. Afraid I can't do that! Also, I almost forgot, I'm not supposed to call you 'Midoriya' anymore. You're just gonna be Deku now! At least, that's how Kacchan wants it, so that's how it's gonna go!" He put back on his big smile, but this time Izuku noticed there was something off about it.

It was the eyes. Kaminari's face was as bright and carefree as ever, but his eyes...they glowed with a gleeful malice the greenette had never seen before on the electric blonde. They looked sinister with whatever dark intent was flowing through his mind.

Despite all this, Izuku was still too confused to piece it all together. "Wh-what? Kaminari, I don't...I don't understand. What's going on?"

"Aww, is poor little Deku confused?" He stepped closer and gave Izuku's cheek a patronizing pinch. "Let me spell it out for ya, buddy. I'm the traitor who's been giving away all your little secrets since we first started high school! It's because of me the League knew where the training camp was year one, and it's how my good buddy Kacchan was able to know about your raid the other day and use it to finally capture you!"

Izuku was stunned into complete silence. His mouth fell open, he couldn't believe what he was hearing.

"Man, he's been moaning about wanting to get his hands on you for a while! Guess you're being a little too willful right now for him to wanna bother with you, though, so it's up to me to break you down into something a little more manageable!"

"N-no. Kaminari, this can't be right. We're friends! Tell me this is just some weird, crazy joke and then let's get out of here! Please!"

"Man, I see what he means. You just like to run your mouth, huh? Well, unfortunately, little Deku, you've already made your first mistake." Suddenly, Kaminari's expression hardened and his voice lost all of its normal chipper quality. "You're a slave now, Deku. You don't get to address me by my name. From now on, you'll address me as Sir."

Izuku didn't respond, didn't even blink. He was too taken aback by the sudden change in attitude from the normally bright and goofy blonde.

"Normally, I'd have you call me Master, but in your case that honor is reserved for Ground Zero." He tilted his head to the side and stared off into the distance for just a moment. Then, as if the previous intensity had been a figment of his imagination, Kaminari's normal lively tone returned. "Though, I imagine in this case, he actually might prefer that you just keep calling him Kacchan!"

Kaminari stepped forward and began to lightly run his hands over Izuku's bare chest. "I gotta say, I'm actually a little glad you didn't give into Kacchan right away. I haven't been anywhere near as obsessed with you as he has been, but I've always wanted to have you at my mercy, ever since I saw you in the locker room for the first time. Let's get started, shall we?"

"Please, Kaminari, you—" Izuku started to speak, hoping to plead with the electric blonde not to do whatever it was he was about to do, but he was cut off when Kaminari used his Quirk to send a burst of electricity straight into his chest. He writhed and cried out, but it was an extremely low voltage, just enough to be uncomfortable and flirt with the edge of painful without doing any real damage.

He kept the shock up for a few seconds before dropping it and stepping back. "I told you, Deku, you'll address me as Sir." He unhooked his Sharpshooting Gear from his arm and set it on the table, before removing the jacket of his Hero costume and draping it over the gear. Lastly, he removed his visor from his face, leaving him in just the black pants and off-white v-neck shirt he wore as part of his outfit.

Izuku's breathing was still heavy from the shock he'd received and he just stared at Kaminari, waiting for whatever he was going to do next.

The blonde stepped back up to Izuku and started rubbing his hands all over Izuku's naked body, gentling caressing every bit of skin, every scar, every muscle. "You have such a great body, Deku. And we could have so much fun with it, together, if you just let yourself go and enjoy it. The more you fight the harder it'll be.

"For you, anyway. Honestly, it's fun for me either way. How about this, I'll start giving you some electro shocks, and after everyone I'll give you the option to ask me to stop. The only condition is you have to call me Sir when you do, got it? Good!"

He didn't give Izuku any actual time to respond before he grabbed onto Izuku's arm and let loose a jolt of electricity. He kept it up for a few seconds, a little more intense than the last one, then finally let go.

"There we go. So, would you like me to stop, Deku?"

"Yes! Please, Kaminari, don't do this!" Izuku responded instantly.

"Ah ah. Wrong answer!" Kaminari placed his hands on either side of Izuku's waist and let loose another shock, longer and more intense, straight into his midsection. Izuku could feel it coursing through every inch of his body, causing him to jolt and spasm.

When Kaminari finally stopped, likely no more than 10 or so seconds later, Izuku was panting and he could feel his limbs twitching in their restraints and his hairs standing on end.

"Alright, how about now? Do you wanna say the magic words to get me to stop now, Deku?" The grin on Kaminari's face was wicked and his eyes danced with pure sadistic pleasure.

"Kaminari, ple—" he was cut off almost instantly this time by Kaminari grabbing a firm hold of both of Izuku's nipples and sending out his biggest shock yet.

Izuku bucked and writhed and pulled against his restraints, but the blonde didn't for a moment let go of his nipples and didn't let up on the electric shocks even a little. The shame and humiliation was beginning to creep back in, because somewhere in the deep corners of his mind, he knew his body was enjoying this.

Just let go and ride the pleasure. It'll feel good if you just let it.

He grit his teeth hard, forcing himself to endure. He wouldn't give in, he wouldn't submit.

Finally the shocks stopped and even Kaminari was panting a little, though his seemed more out of elation and pleasure than anything. "Oh, you're so much fun to play with Deku! And don't act like you're not enjoying it! I can see your little dick straining against your cage."

He flicked at the plastic shell wrapped securely around his cock, that was painfully fighting to be free.

"Now, do you wanna give in and stop?"

Izuku looked up into the blonde's eyes and spit on him. Or at least he tried, the globule fell pathetically short, landing on Kaminari's shoe.

Without hesitation, he slapped Izuku hard across the face before letting out a long, exasperated sigh. "Deku, Deku, Deku. What are we gonna do with you?"

He stood for a moment in contemplation as Izuku's cheek radiated with the pain of the slap before snapping his fingers like he'd just had the world's greatest epiphany. "Ah, I think I know what we can do! I figured out your problem, little Deku. You think too much!"

Kaminari walked around behind the table, out of Izuku's sight. He leaned in close and spoke directly into Izuku's ear, the same way Kacchan had the day before. It sent shivers down his spine the same way.

"Why don't we help you fix that?" He felt the blonde's lithe fingers reach up and cup either side of his head for just a moment before what felt like massive jolts of electricity were sent directly into his brain.

The pain was excruciating, but it didn't feel life threatening, thank god. He had no idea how long it went on for, all awareness of reality seemed to slip away from him as the volt's of the blonde's Quirk coursed directly through his mind.

When it finally, mercifully stopped, he let his head drop, doing his best to catch his breath.

"So what do you think, Deku? Enjoy my little shock straight to your brain?" the lean blonde stepped back around into view as Izuku pondered the question.

It was so hard to think now. His brain felt fried. It was like there were so many thoughts just floating right near the surface, but none of them could muster the energy to actually come to the top. All he could do was give a light grunt, he couldn't think of anything to say.

The electric blonde merely laughed. "Yeah, that should do it. It's a lot like what happens to me when I go too hard on my Quirk. Should leave you nice and stupid for a bit. You'd like that, wouldn't you Deku?"

Deku couldn't think (Deku? That wasn't quite his name, but...sounded correct anyway). He was still aware and conscious, but it was like his brain still had electricity coursing through every neuron at once, overloading his brain entirely. Trying to think about anything for too long just hurt and so he chose not to think at all.

"Hm? I still need an answer from you, Deku. Do you wanna be a dumb good boy for me?" Kaminari lightly grabbed Deku's chin and made him make direct eye contact.

Yes, that's exactly what you want. You want to be a good boy. Just nod for Sir.

That voice from the depths of his mind was so much louder now, seemingly the only thing that could be heard in his mind over the crackling electricity.

Deku nodded. Something about that sounded nice. He wanted to be a good guy, right? That was a thought that was still there. He couldn't really think too hard about how he was supposed to do that, but maybe Kaminari would tell him.

Kaminari, for his part, just grinned wickedly. "Good. I'm glad. Now, let's see if we can't have a little fun." The blonde reached his hand back behind Deku's head and shoved their lips together, his tongue slipping in to explore the grenette's mouth.

It felt amazing, and Deku couldn't help the little moans that slipped in between their lewd making out. Kaminari was even using tiny little bursts of his Quirk to cause tiny little static zaps inside of his mouth. It was such an intense rush and Deku wanted more.

Kaminari pulled back with that wicked grin still plastered on his face. "You taste just as good as I always thought you would, Deku. Did you enjoy that? Do you want more?"

"Y-yes. Please. More." Deku stammered out.

Kaminari squeezed a nipple and gave a warning zap. The pain was just as intense as before, but he found he enjoyed it, letting out a little moan as Kaminari spoke. "Yes what ?"

"Yes Sir!" Deku cried out.

Kaminari let out a rattle sigh of pleasure, like just that one phrase alone was threatening to make him cum. "Good boy. Then let's get to the real fun, huh?"

He operated some controls on the side of the table Deku was strapped to and it leveled out, so that he was lying horizontal to the ground, about waist high to Kaminari. The blond fished a small key out of his pocket and quickly used it to remove the cock cage from Deku's pathetic member. Free from it's confines, it almost immediately rose to it's full, unimpressive height.

"Man, I knew you were small from sneaking peeks in the locker room, but I thought for sure maybe you were a grower or something. You really are laughably small, Deku." Kaminari chuckled as he gave the cock a few lazy pity strokes. "I'm glad Kacchan gave me permission to take that off though; opens up all kinds of fun possibilities for us. Isn't that right, Deku?"

Deku had no idea what the blonde was talking about, so he just default to a simple nod, a stupid smile playing on his face at the positive attention his body was receiving.

Kaminari reached into his back pocket and slid on a sleek pair of black latex gloves, snapping them firmly into place. He then grabbed a bottle of lube as well as a small glass rod off the table. He liberally coated the rod in the lube before using one hand to firmly grip Deku's erection and the other to hold the glass rod directly over his cock slit.

"This'll probably be a little uncomfortable at first, but it'll start to feel good soon, just trust in your Sir, okay Deku?"

Deku cocked his head in confusion but nodded all the same. He didn't really get it, but he didn't get much of anything right now.

Your Sir can be trusted. He'll take good care of you. Just say 'Yes Sir'.

That same voice from the depths of his mind again. It was so loud and clear compared to the rest of his thoughts, so he just went with it. "Yes Sir."

"Good boy." Kaminari replied with excitement as he slowly lowered the rod towards Deku's erection. It pressed against the slit and then slowly pushed its way inside. The feeling was indescribable. It was uncomfortable, but didn't hurt. In fact, it was quickly starting to feel good.

He let out a moan and started to squirm, but Kaminari let loose an immediate shock directly into his cock. "Be still, Deku. Don't wanna make me accidentally tear something down here, do you?" The gloves he was wearing lessened the shock somewhat, but they were too thin to be properly insulated.

Deku did his best to stay still as the rod pushed its way further and further into his shaft, letting out tiny little whimpers and moans as it went. It wasn't long at all until his entire cock was painfully hard and filled with the glass rod, that still stuck out several inches from the head.

"There we go, Deku. You're being such a good boy for me. You wanna keep going and let your Sir make you feel even better?"

Deku nodded his head as he held back for whimpers and cries. This was beginning to feel unbelievably good, and with his brain as shut down as it was, he just wanted to feel more. He wanted to chase these good sensations down whatever rabbit hole they took him.

"Come on, Deku. I know I made you stupid and all, but I think you know there's a proper way to ask me for something that you want."

Beg for it. You're a worthless Deku, so you have to beg your Sir to make you feel good.

Deku was quickly learning not to question that voice from deep in his subconscious that was getting louder and louder. "Please Sir! Please give me more! Make me feel good, Sir! Please!"

Kaminari didn't answer, he simply gave a wide grin and began to slide the rod in and out, fucking Deku's small cock with it. The original insertion was indescribable, but this was pure, unadulterated pleasure. It was overwhelming.

Deku screwed his eyes shut and let out unearthly moans, sounds his mouth had never had cause to make before. They were sinful, and Kaminari was eating them up, as was anyone else who may have been watching.

After just a few minutes, the pleasure began to build, along with a growing pressure in Deku's groin. His moans got louder and louder, he was going to cum.

And then suddenly, it was all gone. The rod was removed, his cock felt empty. He whimpered pathetically. "Sir, please. Don't stop…"

Kaminari caressed his face with the latex gloved hand. "Don't worry, Deku. We're nowhere near done yet. Just didn't want you to cum quite yet. Besides, I've got something new planned for you now, do you want that?"

Deku nodded, that voice in his mind screaming for more pleasure, but his normal thoughts were ever so slowly starting to creep back in.

"First, though, let's reset that big dumb brain of yours, huh? Think you can handle going even harder this time." Kaminari removed his gloves, grabbed Deku by either side of the head and shoved their mouths together, picking up a new makeout session. It was intoxicating, the feeling of the small little zaps as their tongues ran against each other.

Not letting up on the makeout, Kaminari squeezed his grip on the sides of Deku's head and let loose another massive bolt of electricity, straight to Deku's brain. This one was even more intense than the last, and when coupled with the pleasure of Kaminari's tongue wrestling with his own, it was all too overwhelming to keep track of. It was almost like he could feel his brain melting.

The electric blonde finally pulled away with a cry of his own intense pleasure. "Ah! You're so much fun to play with, just as much as I knew you'd be! Now, my dumb little Deku, do you want more of that pleasure that I can give you?"

With his brain as fried as it was, there were no more competing thoughts. No more filter between that voice in his head and his mouth. In this moment, there was no Izuku, no Number One Hero Deku, only Deku the Slave.

"Yes Sir!" He gasped. "Please Sir! More, give me more! I'll be good Sir, I promise, just give me more!"

Kaminari almost looked like he could cum right then and there from the way he shivered with pleasure. "Good slave. You should be rewarded for that." He slipped back on his sleek black gloves and grabbed another rod off the table. This one was made of metal and was slightly larger. He lubed it up thoroughly and then grabbed onto Deku's cock, which was harder than it had ever been in his entire life.

He let out a rasping gasp of pleasure, practically quivering in anticipation of what was to come. This time, as the metal rod slid down into his cock, there was no discomfort, only pleasure as his stupefied brain basked in it, sinful moans falling from his lips.

"Thank you Sir! Thank you Sir! It feels so good!"

Kaminari chuckled as he began to fuck Deku's cock with the rod. "Who knew you already had such a good little slave tucked deep inside you? Maybe you won't need as much training as I thought, huh Deku?"

"No Sir! Deku is a good boy! Just don't stop, Sir! Please!"

"Oh don't worry, slave. We're just getting started."

Kaminari kept his left hand sliding the rod in and out of Deku's slit, but moved his right hand, the glove still coated in lube and reached down between Deku's legs. He pressed a button on the table, and the pieces his legs were strapped to began to move, spreading his legs apart and exposing his hole, still a little sore from Kacchan's fucking the day before.

The blonde took his middle finger and began to gently rub it around the outside of Deku's hole, teasing it over and over with the promise of insertion, but not yet delving inside. "Do you want it, Deku? Do you want me to finger your hole open?"

"Yes Sir! Finger my hole! Use me Sir, please!"

"Then you have to earn it. Cum for me slave. Cum around the rod." He redoubled his efforts, teasing firmly around his hole, using just enough pressure to almost push in, but not quite, and fucking the rod into Deku's cock faster.

The command given, it took only seconds for Deku's moans to grow in intensity until he was blasting cum out around the rod that was still firmly planted inside his pathetic shaft.

The slave was lying on the table, panting and gasping through his orgrasm, trying to catch his breath, but Kaminari was not a kind master. Despite how good Deku was being, he wasn't going to give him a moment's rest. He immediately pushed his full finger inside the slave's hole, burying it as far in as it would go, and causing the slave to cry out in a mixture of pain and pleasure.

"Thank me for allowing you to cum, slave." Kaminari forcefully commanded as he began to fuck his finger in and out of Deku's hole.

"Thank you Sir." Deku managed to gasp out. "Thank you...for letting me...cum…"

"You're welcome, slave. Now let's continue. I'm about ready to have a little fun of my own." He quickly added two more fingers, stretching open his hole, preparing him for what was to come.

The rod stayed in place, even continuing to be slid in and out of him every so often, but even when it was still, the sensation of his cock being full of this foreign object was overwhelming. When coupled with the fingers in his hole and the orgasm he was still recovering from, the stimulation was at a level he'd never experienced before without falling unconscious like he had yesterday.

After another minute or so of prep, Kaminari removed his fingers, leaving Deku whining at the emptiness in his hole. "Shhhh. It's okay, Deku. You'll have something new in there in just a moment. Just have patience."

He stepped in between Deku's legs and undid his pants, fishing out his cock. It wasn't anywhere near as big as Katsuki's massive dick, but it still dwarfed Deku's all the same. "It's a shame I don't get to be the first one in this ass, but it just makes sense that that honor would go to your Kacchan. Oh well, it looks like your body does a good job of tightening up even after being stretched so wide, so this should be fun."

He lubed up his cock and wasted no time pressing the head inside Deku's hole. "You've already been fucked by one of the biggest cocks we have, so no need to be gentle with you." He slammed the whole thing fully inside the slave's tight ass, causing him to cry out and get pushed right to the edge of another orgasm.

Kaminari moaned as he felt the tight hole squeezing hard on his cock. "Fuck, you're such a good boy, you feel so good, Deku."

He glowed from the praise. "Thank you, Sir. Please...fuck me. Fuck me, Sir."

Kaminari let out a single chuckle. "Now how can I refuse a request like that?" He immediately pulled all the way out and then slammed back in, pounding into the slave with a rough force you wouldn't predict from the lithe blonde.

"Now...comes my favorite part…" Kaminari grunted out as he fucked into the slave. He used his teeth to remove one of his gloves and then gripped the end of the metal rod that was still firmly planted inside Deku's dick.

He let a wicked grin spread across his face as he activated his Quirk once again, sending electricity coursing down the road and straight to the inside of Deku's cock.

His mind went completely blank and his vision went white. The only thing he could feel was white hot pleasure coursing through every nerve ending in his body. When Kaminari turned off his Quirk and he came back to reality a few moments later, he had managed to cum again, coating the rod in white as Kaminari continued to fuck into him harder and harder.

The electric blonde's breathing grew faster and heavier and only a few moments later, he was burying his cock deep into the slave's hole, and Deku could feel his cum flooding his insides.

Kaminari collapsed forward onto Deku, catching his breath, careful not to hit the metal rod. Eventually, his cock softened enough to fall out of the slave's hole, so he stood and tucked it back away inside his pants, slipped his removed glove back on, and removed the rod from Deku's winking slit.

"Excellent work so far, slave, but we're just getting started. Here, let's keep you hydrated and then get back to work, shall we?"

Kaminari allowed him to drink down some water from a bottle tucked underneath one of the tables and gave them both only a moment to catch their breath before getting right back to it.

They went at it for what was probably the next several hours, but it was hard for Deku to keep track since Kaminari kept periodically short circuiting his brain to ensure he was in a properly stupid state to be a good submissive slave. Deku wasn't complaining though. As far as he was concerned, or at least the little voice within him which had grown to take over almost all of his mind was concerned, this was the best he'd ever felt in ages.

He came countless times and in various positions. Kaminari continued to use various sounding rods on his cock, shock him in every part of his body he could reach, fuck him with dildos of ever increasing size, and even make out with him every so often.

At one point, the blonde decided he wanted a break and so left Deku lying there strapped to the table, with some kind of machine fucking a huge black dildo in and out of his hole and the largest metal rod yet sticking out of his cock. "I'll be back in a little while, Deku. Don't cum while I'm gone and I'll give you a reward."

He had no idea how much time had passed before Kaminari returned, but he'd stayed a good boy. He hadn't cum, though he'd come close a few times. "Such a good boy," he heard him speak from the doorway, "I'm so proud of you. Now for your reward. You know those rods are made of a similar material to the discs from my shooter. Which means, I can target my electricity right to them." He held out his hand in a finger gun shape and suddenly electricity was arcing from his finger tip, flying across the room and straight into the end of the metal rod, coursing from there straight down into his cock and through the rest of his body.

For the second time that day, he felt that white hot pleasure blinding him to all else, and causing him to cum for what felt like the hundredth time in just two days. When reality finally came back to him somewhat, the rod was being removed and his face was being gently caressed by the other significant blonde in his life.

"Kacchan…" Deku breathed out with a happy little sigh, a weak smile playing across his face.

"You've been such a good boy today, Deku. I'm so proud of you. I knew you could do it." Kacchan's praises were like ambrosia from the heavens. He felt so warm having his master's approval.

Master? No, Kacchan's not my master...this isn't right…

His brain was starting to recover a bit, which meant Izuku was starting to come back. Something must've registered on his face, because Kacchan looked up towards Kaminari. "Alright, Pikachu, go ahead and give his brain another zap, and then I'll take him for the night."

"You're the boss! But this is my last one for the day, unless you want me to fry my own brain too. Been dancing on the edge of that for a while now." Kaminari said in the bubbly, chipper tone that Deku had always heard from him in their UA days.

The electric blonde gripped either side of Deku's head once more and sent one last full blast of electricity straight into his mind, frying out his thoughts and sending Izuku back down into the depths for a while.

Once that was done, Kacchan removed the restraints and gently lifted Deku into his arms, bridal style. The slave let his head fall into Kacchan's broad chest, closing his eyes to rest just a little.

When he awoke, he was fairly certain it was only a little while later. He was resting in a large bath, filled with hot water.

"Ah, you're awake again." Kacchan was sitting on the edge of the bath and looking down at him. "You did so well today, Deku. I was watching the whole thing, and you behaved so well for Pikachu." He gently ran his fingers through his curls, and Deku leaned into the touch. "You fell asleep for just a bit, so I went ahead and cleaned you up and put you in the bath. You stay here and relax, I'll have some food brought to us. I'm sure you're hungry."

His stomach grumbled in response, causing Kacchan to chuckle. "I'll take that as a yes. Stay here, I'll be back soon."

Kacchan stepped out of the room and Deku relaxed into the warm water, letting it soothe away the aches of the last two days. Looking himself over, he had a few marks along his wrists and ankles from the restraints, his cock was back in it's little green cage, and he actually had a small lichtenberg scar on the right side of his neck and shoulder from the repeated electrical shocks.

Kacchan returned a little while later to get Deku out of the bath and led him into a large, and well furnished bedroom. It was clearly still part of the same underground complex based on the concrete flooring and rough hewn walls, but it had several pieces of well made wooden furniture, all painted black with various orange accents. A large King-sized bed was the central piece and sitting atop it was a tray of delicious looking food, the most obvious of which was a steaming bowl of Katsudon.

Deku immediately started to step forward for the food before stopping for a moment to look back towards Kacchan, silently begging permission to eat.

Kacchan chuckled. "Go ahead, Deku. Eat."

He needed no further permission as he dove onto the bed, grabbed the provided chopsticks, and devoured the meal like it was the first thing he'd eaten in days. Which was because it was the first thing he'd eaten in days.

Kacchan smiled softly at the sight before sitting on the edge of the bed and just watched Deku eat.

Over the next few minutes, he ravenously devoured the entire meal, leaving not a scrap behind, before collapsing onto the bed, fully stuffed. Kacchan cleared the tray from the bed with a light scoff. "What, no gratitude?"

He immediately felt shame and embarrassment flood him as he dove into Kacchan's chest and wrapped his arms around the firm waist. "I'm sorry! Forgive me! Thank you, Master! Thank you for the bath and the food! It was very generous of you!"

Kacchan laid back into the pillows and rubbed his hands into Deku's hair. "It's fine, Deku. When you behave as well as you did today, you should be rewarded like this. And you don't have to call me Master unless there are other people around. I prefer it if you call me Kacchan when it's just us."

Deku smiled into the broad chest beneath him. "Okay Kacchan."

They cuddled like that for a little while before Deku felt himself get frisky and started to grope at Kacchan's huge cock through his slacks. The blonde had no objection and rolled over onto his slave, tearing off his own clothes.

They spent the next hour fucking in every position they could maneveur into on the bed, Deku moaning and begging for more as Kacchan fucked him into the mattress and filled him with cum.

Eventually, they both passed out naked in each other's arms, but not before Deku's plug had been securely placed in his ass to keep the cum from leaking out.

When Deku awoke, he could feel something warm underneath his head and wrapped around him.

Wait, did he just think of himself as 'Deku'? That wasn't right. No, his name was Izuku. Izuku damn it. He blinked his eyes open rapidly and discovered that he was still completely naked and was cuddled up into an equally naked Kacchan, who was currently fast asleep.

It took all of his willpower, but he managed not to panic and give any kind of outward reaction that might wake the blonde beneath him. With painstaking slowness, he carefully extracted himself from the cuddle position and climbed out of the bed. Kacchan stirred ever so slightly, causing Izuku to freeze in place for a moment, but he merely rolled over and slipped immediately back into his slumber.

Izuku let out the faintest of relaxing breaths and took a moment to evaluate his situation.

They were in some kind of bedroom, but it didn't have much furnishing beyond the large king sized bed. There was no dresser or closet where he might find clothes to cover up with, and the towels they had used the night before in the bath had been taken away from the attached bathroom. The only options he had to cover up with were the bed sheets and the clothes Kacchan had been wearing yesterday, currently scattered across the floor.

He didn't dare try to remove the sheets for fear of waking Kacchan and just a cursory inspection of the blonde's discarded clothing revealed it would be far too big for Izuku to wear. The bagginess would restrict his movement, and he needed to be unhindered if he was ever going to get out of here.

One thing he had managed to discover was that the small plastic cage that had been put around his cock was still removed, so at least there was that. Staring down at his cock, he felt a strange mix of anger, shame, humiliation, and (much to his dismay) arousal.

A lot of what had happened yesterday was a bit of a blur in his memory, but he remembered enough. He remembered the revelation of Kaminari's betrayal, the way the electric blonde had tortured him and short circuited his brain so badly that all he could focus on was the pleasure. He'd been fried so bad that it was almost like an entirely different person had taken over his consciousness, and that person had been exactly what Kacchan had been wanting: a slave desperate for more of this abuse.

Come on, wasn't it so much more fun to be Deku? Being Izuku is so boring, just let go and let Deku take over again.

Deku—no, Izuku; his name was Izuku—shook his head of those thoughts as best he could, gritting his teeth and letting the anger win out above everything else.

He needed to get the fuck out of here so he could get these cuffs off, get his Quirk back in action, and come back to take Kacchan and his organization down for good. Since he couldn't find any clothes that would be suitable, he'd just have to make his escape naked. He made his way over to the door, silently praying it wouldn't be locked in any way.

He breathed a sigh of relief as he turned the handle and the door opened without issue. He summoned every element of stealth training he'd ever had and peeked out the doorway. Seeing an empty hallway, he crept out and silently shut the door behind him. Unfortunately, he had no idea where he was, other than it was most likely some kind of underground facility, since he hadn't seen a single window.

Having no idea where to go, he picked a direction at random, and began to silently stalk his way through the halls. The whole place was like a giant maze, but he did his best to focus his mind on mapping out every turn he took to ensure he didn't start going in circles. He'd come across several patrolling goons, but so far no one who was moving solo.

His ideal plan was to find someone who was on their own, someone who he could get the drop on and force to show him the way out. He didn't have access to his Quirk, but he was still a well-trained fighter with a fair bit of muscle to work with, despite his smaller stature, so he could take most of these goons one-on-one without issue. Honestly, he could probably even take two-on-one, but he'd prefer not to risk that, especially with the factor of not knowing any of their Quirks mixed in.

After several minutes of maneuvering through the winding hallways of the villain's lair, hiding from patrols and searching for a way out, he finally found what he was looking for. There was a single individual standing in the hallway ahead of him, back turned towards him, and they appeared to be totally alone.

As Izuku crept forward, he realized he actually recognized the individual. It was the League of Villains' reptilian member Spinner. He was a formidable foe, but his Quirk didn't really help him in combat and he didn't appear to have any of his blades on him at the moment, he was just standing in the hallway, reading something on a clipboard.

Izuku crept up behind the unsuspecting villain and in a flash wrapped his arms tightly around Spinner's throat, squeezing hard enough to show he meant business, and harshly whispered into his ear. "Alright, Spinner. Don't struggle, or I'll have to hurt you. I've had a really tough few days, so I wouldn't test me. Show me the way out of here, and I'll let you go without issue. The other villains don't even have to know you told me, or that we even saw each other."

Spinner seemed to contemplate this for a moment before giving a small nod. "Fine. It's just this way, down the hall to the left."

"Good. You don't mind if I bring you along, just to make sure you aren't lying or that you won't pull the alarm, right? Excellent, let's go." Izuku kept a tight grip on Spinner, pushing him down the hallway, following the reptile's directions, before eventually laying his eyes on his prize: a side exit to the facility.

It was a clearly marked door, the only thing between him and it was some kind of metal archway that looked like a metal detector of some sort. He pushed the villain forward with increased urgency, eager to get outside and make a bolt for whatever form of civilization he could find. He didn't even care that he was completely naked. It would make for a crazy news story, but he didn't care. Freedom was almost his.

It wasn't to be, however.

As he and the villain pushed beneath the metal detector, there was a loud, angry beep and then suddenly a harsh jolt in both of the wrist cuffs that were blocking his Quirk. It was so intense that he released his grip on the villain and dropped to the ground, writhing in pain.

Spinner turned and gave a sharp kick to Izuku's side. "Stupid hero! Did you really think you could get away that easily? That we didn't have safeguards against escapees? Come on, let's see what your owner wants to do about this disobedience."

The villain gripped Deku—no, Izuku—firmly by the hair and began dragging him down the halls. He tried to struggle, but the lingering pain from the wrist shock was slowing him down and he could do little more than flail helplessly.

He was so tired of feeling helpless.

Then stop struggling. Accept your new place, and you won't feel helpless anymore.

Izuku growled in anger at the unwanted thoughts whispering from the corners of his mind.

Finally, they arrive back at the bedroom he'd escaped from, being unceremoniously tossed to the floor in front of a furious looking Kacchan, now fully awake and dressed in his full villain attire. It gave him a menacing aura that shot a shiver down Izuku's spine.

"Damn it, Deku. I thought you'd finally learned. Was I not good enough to you last night? Did I not bathe you, and feed you, and take care of you? You disappoint me. Maybe you don't have what it takes to be my slave, after all." He let out a sigh and Izuku felt a pang of shame that he quickly tried to force down.

"Guess not, Ground Zero. I suppose that means you'll just have to let me go." Izuku replied in the most spiteful voice he could muster, which unfortunately didn't have much weight behind it.

Kacchan grimaced at Izuku's use of his villain name, but it quickly morphed into a sneer. "That's not quite how it works, Deku. I showed you what it's like to be my slave, how you're rewarded when you do well. Now you get to see what happens to you if you refuse to cooperate. How it feels to be everyone's slave." He tilted his head towards the open doorway. "Saru! Get in here!"

Izuku turned his head and saw one of the massive goons with the Gorilla Quirk from the other day enter the room, needing to duck to fit through the doorway. "Yeah, boss?" he asked in the gruffest voice Izuku had probably ever heard.

"Take him away. Put him in the wall. Tell the others: nothing permanent," Kacchan locked eyes with Izuku, "but otherwise he's free game." Izuku felt another chill down his spine. He didn't know what any of that meant, but he knew he wasn't going to like it.

The Gorilla goon, Saru, grabbed Izuku with both hands, completely pinning his arms to his sides and walked off with him down the hallway. Izuku tried to put up a struggle, but he knew before he began that it was useless, just like everything else he'd done to escape his captivity in this place.

"Squirm all you like, pipsqueak, it just makes it more exciting." Saru said with an ominous tone.

After a few twists and turns that Izuku did his best to memorize, they entered a room that chilled him to the core. It was empty of any furnishings. The only distinguishing feature was a series of holes in the far wall, several of which currently had the lower half of naked people sticking out of them.

Their legs were secured to the wall, and their asses were presented out at waist height. There were both men and women, with cocks, asses, and pussies bare and exposed. Cum, both fresh and dried coated the majority of them, leaving zero doubt as to what went on in this room.

The most horrifying part was the pictures, though. Above each person, there was a picture hung on the wall of a different hero. They were all heroes who had gone missing while on assignment in the last several months, and the worst part was that he knew several of them. He saw pictures of Tsuburaba, Kendo, and Monoma from the old Class B and he felt a pang in his chest as he saw the picture of Aoyama above a plump, pale white ass. Aoyama in particular looked quite abused, his hole practically gaping from who knows how many villains that had used him.

They'd all gone missing in the last month or two, but he hadn't for a moment imagined that this was what was happening to them. All of them were coated in semen and had it dripping out of their holes. At the very least, he was able to breathe a little more easily as he saw all of them occasionally adjust and shift, indicating they were at least still alive. He assumed they were all wearing Quirk suppressing cuffs like he was inside the space behind the wall, otherwise they would've been able to easily break free.

Then his eyes fell upon one of the few empty holes in the wall, above which was hung his own picture. It was from a profile his agency had put up on their website. He remembered the day he'd been forced down to a studio to have it taken; he hated it.

He'd give anything to be back there now.

You did this to yourself by trying to escape. Just beg Kacchan's forgiveness. Promise to be a good Deku and then you can avoid this.

Izuku bit the inside of his cheek hard to try to silence those thoughts as Saru carried him towards the hole. "Boss said you're free game as long as nobody does any permanent damage to you." Izuku saw the lumbering ape of a man grin out of the corner of his eye. "But I'm gonna take first go at your sweet ass myself before I let them know the good news."

Saru manhandled him inside the hole, revealing the other side to be little more than a tiny cubicle with a padded surface for him to lay on, chains secured to the wall on either side of him, and a single metal door directly ahead of him that was presumably accessed from some other part of the compound.

Izuku tried to fight and kick free, but Saru was easily able to force his legs down and into the restraints, leaving his ass hanging out of the wall, his cock dangling loose between his slightly spread legs. The hole was positioned in such a way that even though his arms weren't currently restrained, he couldn't contort and angle himself enough to slide out of the wall.

He felt a rough hand squeezing his ass and heard a low growl of anticipation followed by the sound of a belt being undone. He felt something cold and slick being poured onto his hole and then there was a massive, bulbous head trying to push its way inside him.

After all the abuse his ass had taken over the last few days, he was pretty loosened up, but this cock felt truly gargantuan. The head finally pushed in with a small 'pop' and Izuku cried out from the intense stretching of his body around this massive cock.

"You know, a lot of the boys are gonna be pretty upset that I'm stretching you out so bad right off the bat, but fuck it. I never get to go first, and your ass is just too good to pass up." Saru grunted out as he slid his cock deeper and deeper into Izuku's guts.

"Fuck, fuck, fuck." Izuku gripped the chains on the walls for support. It was too much. Too fucking much. This was even bigger than Kacchan's cock. The thing had to be almost a foot long and he hadn't even bottomed out yet. "Please, stop. I can't take anymore."

"That's right. Beg and cry. Just makes this better for me. All the other fellas are gonna love it too, so just keep that up!"

Finally, he felt the Gorilla goon's massive hairy balls pressing against his ass cheeks. He'd taken the whole thing. He felt like he could feel it inside his stomach, and was afraid to look down and see if he was right.

He wasn't given much chance to adjust, though, as Saru slid his cock half way out and then slammed it all the way back in, starting to fuck Izuku's ass at a hard, steady pace. "Fuck, you've got the tightest ass I've ever fucked! Gonna have to thank the boss for letting the rest of us at you."

Deku couldn't help himself as he felt his ass be turned into a cocksleeve for this gargantuan man, he looked down towards his stomach and could see it ever-so-slightly bulging out with every thrust.

Fuck that's so hot.

Izuku shook away Deku's thoughts as best he could, though it was difficult to do so when Saru's cock was pressing hard against his prostate with every thrust.

Eventually, the pace began to quicken and there were loud huffing grunts that almost sounded like they were coming from an actual gorilla, before he heard a loud roar accompanied by a hot wetness flooding his now abused asshole. There was so much of it, he was already feeling bloated from just the one load.

He felt the cock vacate him, leaving his hole gaping and allowing a large amount of the cum that had just been shot inside of him to come gushing out of his ass and sliding down his legs onto the floor.

He was pretty spent, but he vaguely registered the sound of Saru buckling his pants up and leaving the room. He was left in silence for only a moment though, before the door in front of him slid open and Saru stepped inside. Izuku looked up at him with what must've been a pretty dazed and fucked out look.

Saru chuckled. "Don't get too excited little slut. I had my fun for now, I'm just here to finish securing you. Don't worry though, you should have guests real soon once I spread the word." He reached over and attached each of his wrist cuffs to the chains in the wall and ensured they were secure before turning and leaving without another word.

His prediction turned out to be correct, as not more than ten minutes later, he heard the door to the main room behind him open and the sound of several male voices filled the room.

"Fuck, the ape wasn't kidding. He's really here!"

"Shit, you're right. Can't believe the boss is really letting us have free reign over his little pussy boy."

"The only rule is no permanent marking or damage, right? Fuck, this is gonna be fun."

He felt a pair of hands caressing and squeezing his ass cheeks. "Such a nice fucking ass he's got too. Look at all the freckles! Can't wait to coat them in my cum."

Another hand reached down and played with his cock and balls. "Damn, look how fucking small he is! You'd think the big, bad Number One Hero would be hung as fuck or something, but he's barely got three inches to work with here."

"The fuck you playing with his cock for? Not like any of us are here for it anyway. Let's get to having our fun!"

"Yeah, shame the ape had first go. Punk's hole is way too stretched now." Izuku felt two fingers press inside his sloppy hole, easily slipping inside after the massive entry he'd suffered earlier.

"Doesn't fucking matter to me, long as I can feel it. Get out of the way, I'm goin' in." The two fingers were harshly removed as their owner was shoved aside and Izuku heard yet again the sound of pants being opened.

"Please...don't do this…" Izuku whimpered pathetically from his little cubby hole.

"Oh yeah." The sound of the stranger's voice was practically orgasmic, and he hadn't even done anything yet. "Japan's strongest hero, the Symbol of Hope, begging me not to fuck him like a cheap little whore. This might be the best day of my life boys."

He heard the other men chuckle, but barely had time to register it before a modestly sized dick shoved it's way inside his ass, burying all the way to the base in one hard motion.

Izuku cried out in surprise, but he'd be lying if he said it hurt. Not after what he'd just endured less than thirty minutes ago.

"The ape already got him about as loose as a person can get, so no need to be gentle right?" With no further words, the stranger began to ram his cock inside Izuku's hole over and over again.

It didn't take long at all before the man was grunting and panting heavily. "Let's give this freckled ass a nice coating of cum, really make him look like the whore he is!" The man cried out in orgasm as the cock was ripped free and warm blast after warm blast of cum was painting his ass.

But Izuku got no reprieve.

"Move over, it's my turn!"

The man was shoved out of the way, his cock being yanked out and almost immediately replaced by another, who was equally as unforgiving as the last.

Izuku didn't even bother to struggle. He knew there was no point. He was securely chained and had no Quirk. Struggling would just tire him out even faster, so he did the only thing he could do. He laid there and took it.

Over and over again. For hours. Men would come in and use his hole until they came deep inside him or all over his ass. Their loads coated his ass and the floor. Some of them would jerk off his cock too, making sure he came over and over as well.

He recognized the occasional voice of League of Villains members who he'd faced before using him, and he could tell when Spinner decided to take his turn. His scaly, reptilian cock was an intensely unique sensation that he would probably never forget. For the most part, though, they were all strangers. Villains and thugs who he'd never met, all lining up to use his body for their own pleasure.

He could hear some of his fellow captives being used as well in the nearby cubbies, but today he was by far the main attraction.

Through all of it, he just laid there in cold, indifferent acceptance. The voice in his head, the one he associated with 'Deku' kept trying to come out, to let him enjoy it, but Izuku refused to give in. There was nothing he could do to stop this, but he would do everything in his power to not let himself enjoy it. To not break the way they wanted him to.

Then came his first reprieve. Meal time. As he came to understand it, the "fuck holes", as the villains referred to them, weren't released from their confinement, but the main room was locked for a short time and food was brought and fed to them.

It wasn't until the bowl of slop was placed in front of him that he realized just how hungry he was. He looked up to the guard expectantly and jangled his chains as if to communicate his point.

"Huh? Oh right, you're new here. If you wanna eat, you better do it just like that. You've got a perfectly good mouth, you can put it to use." The guard said with a sly grin.

Izuku glared at him, but he was too hungry to protest. Besides, much like everything else in this hell, it was pointless to struggle anyway. Might as well go along with it.

Yes, that's right. You're finally starting to learn.

Izuku pointedly ignored that thought and buried his face into the bowl to start eating. The taste was pretty terrible, but he was hungry enough that he didn't care. He devoured the whole bowl greedily before the guard took it away and harshly wiped the excess away from his mouth and chin.

"You fucking whores. Never amazes me how much of a pig you can all be." The guard scoffed as he walked away, sealing the door behind him.

It wasn't long at all before Izuku started to notice something was wrong. He could feel his whole body heating up and his dick hardened as he began to writhe in place, his ass clenching and suddenly feeling insanely empty.

The realization hit him in the face like a hammer. They'd drugged the food. Some kind of aphrodisiac, and a highly potent one if the rapid onset of effects was anything to go by.

Izuku was barely holding back moans just from the way he was squirming around in pleasure by the time the doors to the main room reopened and a flood of villains came into the room.

Ah, here we go. Now that we've been drugged, you can really let go and enjoy yourself.

Deku was right. Why shouldn't he enjoy himself? If he was gonna be stuck here like this, he deserved to at least feel good, right?

"Oh fuck yeah, fuck me! Fuck my hole!" Clearly someone agreed with him. Monoma by the sound of the voice in the cubby next to him. He was starting to hear other moans of pleasure and begging for cock from the other captured heroes. They must've all been drugged, maybe it was a regular occurrence.

Izuku didn't have time to think about it, though, before a pair of firm hands was gripping his ass on either side and lining up their cock with his fuck hole.

Just let me out, Izuku. Let Deku take over and you can really enjoy yourself. You know you want to.

Izuku only contemplated it for a moment before he was speared by another hefty cock, and as it bottomed out inside him, he decided to let go.

"Fuck yes!" Fully free, Deku shouted out his joy at being fucked yet again. He longed to be with his master again, but he understood that this was his (or rather Izuku's) punishment, so he would experience it to the fullest.

And experience it he did. For the next several hours, different cocks fucked him over and over. Cumming inside him and all over him. He wished he could lick them clean, but that wasn't really part of the deal here. He did thank each villain for giving him their load, and he moaned and begged for more every time.

By the time the aphrodisiac finally wore off, the room was being shut down and locked up for the night and he was completely exhausted. A few of the guards, probably men who'd already fucked him, hosed him and the other captured heroes down and then unchained their wrists and legs and gave them some pillows to sleep with. They were pulled inside the cubbies, the holes having a sliding panel close them off so that they wouldn't be able to communicate with each other, not that he would've had the energy to try.

He quickly passed out and didn't wake again for hours.

This process repeated for several days. He'd lost count of just how many. Each morning he'd be woken up by the panel of his hole in the wall being opened and his lower body being dragged out and secured before a guard would come into his cubby and secure his wrists.

Occasionally, the guards would even take advantage of his throat while they were in there too.

The second day, when meal time came, he attempted to refuse eating any of the food, since it was likely drugged again.

All he got for his trouble was his head held in place while a guard force fed him.

Being fed this aphrodisiac every day was making it easier and easier for Deku to come out of the recesses of his brain and take over, begging for villain cock and cum, and he no longer felt any pain from being fucked, no matter how large the cock. Even Saru had taken a few more turns, without causing anything more than momentary discomfort.

But each morning, he'd wake up as Izuku again, desperate and miserable.

Just stop fighting. There's no need for you, anymore, Izuku. You're only hurting yourself. Let Deku take over for good and everything will be all better.

Thoughts like those were becoming more and more common, but Izuku just bit his cheek hard to ground himself. He refused to give in.

This morning, though, something became suddenly different.

The door slid open as always, but instead of a guard, it was Kacchan stepping inside.

Deku's excitement couldn't be contained. "Kacchan!" But he tamped it down as hard as he could. "What do you want?"

"Tch. Still fighting the inevitable. I was really hoping you'd have given in by now." Kacchan stared down at him with disappointment.

Izuku, despite the shame creeping at the edges of his mind, mustered up his deepest glare. "Never."

Kacchan's disappointment shifted into a smirk. "We'll see about that. I'm not quite done yet, Deku." He turned around and grabbed something from outside the room and returned with a pair of hair clippers in hand. With his other hand, he gently caressed through Izuku's curls, and he had to fight the urge to lean into the pleasant sensation.

"It's a shame that I have to do this, your curly hair is so beautiful, but you've left me no choice." He grabbed tighter onto the hair suddenly, yanking it to pull his head up and leaning in close to his face. "I'm going to strip away everything that makes you 'Izuku' so that only 'Deku' is left."

He dropped him harshly and then flicked on the clippers. "Don't squirm Deku, don't wanna cut you."

Izuku didn't heed his advice and began to try to pull away. Kacchan merely sighed and snapped his fingers. A moment later, Saru entered and the two of them pinned him down and attached his wrists to the wall chains, the gorilla goon grabbing Izuku's head and holding it firmly in place.

Kacchan got to work, buzzing off huge chunks of his hair. He watched in horror as clumps of green curls fell to the floor and shuddered to think what he must look like.

He didn't have to wonder long, as Kacchan made one last buzz across his scalp and then clicked the clippers off. He stepped back and admired his handiwork before pulling a small hand mirror out of his back pocket, holding it up to his face. "What do you think, Deku?"

Izuku glanced up into the mirror and felt nothing but defeat. His head was buzzed completely clean, only the barest hint of green stubble left on top. He felt defeated. Defeated and weak.

Just a weak, pathetic Deku.

He couldn't even deny the thought this time. He still held on, hoping against hope for a miracle to save him while there was still a "him" to save, but in this moment he was weak. He was pathetic. He looked up from the mirror into Kacchan's face, and didn't even want to know what expression was on his own.

Kacchan merely patted him gently on the cheek. "That's better. Now, just a few more things." He held out a hand to Saru who handed him a small syringe. "We've been getting into the drug market lately, and have been working in particular on aphrodisiacs. You and your fellow slaves have been helping with the testing process, as a matter of fact, but we've got a couple new variants that we want to try out."

He flicked the end of the needle a couple times, inspecting the syringe to ensure all was in order. "One of them isn't quite ready, but we're hoping to have a new test subject for it very soon. This one though, is ready for it's first big trial run. It's a lot like what you've been eating the last several days, but this one's a lot stronger."

Without warning, Kacchan stuck it into his neck and pushed down the plunger. Izuku felt a rush of warmth spread from his neck and all throughout his body. His cock reached full hardness in seconds, and he couldn't stop the moan that gushed from his lips.

(Important bits for those who skipped: Izuku got drugged and Kacchan is making aphrodisiacs)

Kacchan laughed. "Looks like it works. Now that's probably gonna be in your system for quite a bit, so let's take full advantage of it, what do you say Deku?"

The heat and pleasure coursing through him was almost too much to contain, and Deku was screaming for control. Izuku managed to maintain and said nothing, merely squirmed in his restraints.

"Enjoy those last bits of control, Deku. They'll be gone soon." Kacchan left the room for a moment and returned carrying some kind of VR headset, which he immediately forced over Izuku's head. The screens inside were currently black, but his mind was racing trying to figure out what was going to happen. Effectively blinded at the moment, he was startled when he heard Kacchan's sultry voice speaking right against his ear. "Have fun, Deku. See you soon."

He was then effectively deafened as noise cancelling earbuds were pushed into his ears, leaving him trapped in a dark and soundless void. His arms chained to the walls, his Quirk suppressed, his ass hanging out into a room to be used by whatever villains wanted a go, and an exceptionally strong aphrodisiac coursing through his veins.

Time was already getting a little fuzzy, so he wasn't sure if it was a few seconds or a few minutes before the screens of his headset flickered on and sound began to come out of the earbuds.

The image was some kind of strange swirling pattern of lights and colors and lines. It was actually quite pretty, but hard to focus on any one spot as it kept swirling and shifting and changing. The sound was some kind of odd buzzing that shifted in tone and pitch constantly. Something he was aware of but couldn't quite focus on.

Suddenly, the swirling pattern became translucent and behind it he could see images and video clips. They were all of him! It was photos and videos of what had been done to him here so far. His first night, strung up to the ceiling in his cell while Kacchan abused and fucked him. His day of torture with Kaminari. All the villains who had been using his hole the last several days. It was all there, in full vivid detail.

Accompanying the new images there was some kind of text flashing onto the screen every few seconds. It came and went so fast that he couldn't focus on it to read what it said, but he could tell it was just a word or two at a time and seemed to keep changing.

After just a few seconds of this, his earbuds began to emit a new sound in addition to the strange droning noise. It was a calm yet masculine voice, saying simple phrases in no particular order he could decipher. But it was the content of the phrases that sent a chill down his spine.

"You are Deku"

"You are a slave"

"There is no Izuku Midoriya"

"You are weak and open to being controlled"

"You must obey"

You are a good Deku"

"Izuku Midoriya does not exist"

"You become weaker every day"

"You will serve Kacchan, your master"

"You love to obey"

"You do not resist"

"You love being a toy for villains"

"Kacchan is your master"

"You love Kacchan"

Over and over. Again and again. The phrases repeated, the images and words flashed, the pattern swirled, the noises buzzed and droned, the drugs coursed through his system keeping him constantly aroused.

He was dimly aware that his body was once again being used and fucked by villains as he was stuck in the wall and that his mouth was moaning in overwhelming pleasure, but it quickly became extremely difficult to focus on any one sensory input at a time, since his brain was trying to focus on them all at once and failing.

Time ticked away, but he had no idea how much. It could've been minutes, hours, or even days. Deku had no idea. All he knew was the ecstasy he was experiencing from every angle, losing any desire to fight against it. He let go and let it carry him off into a sea of pleasure.

Katsuki stepped out of his meeting feeling a sense of satisfaction. Everything was coming together nicely for their little trap. They needed a test subject for the new strain of their aphrodisiac and he had just the person in mind.

Now to go check on Deku's progress. He'd been in there for a good nine hours or so, and he'd been assured this program would only need four to truly break him. Feeling an almost youthful sense of eagerness and excitement, he headed towards Deku's little cubby hole.

As he arrived outside, he commanded one of the guards to clear out whoever was using the slave wall for a little bit. He didn't want any distractions for this.

Stepping inside the small chamber, he was overcome with lust at the sight before him.

Deku's head was lying limply against the padding beneath him, as his body continued to squirm from the lingering effects of the aphrodisiac. His mouth was hanging open in a dumb grin, his tongue was hanging out to the side, and there was a puddle of drool leaking from his lips.

With a victorious grin, he switched off the program and slowly removed the headset and earbuds, setting them off to the side before gently stroking Deku's cheek. "Time to come back now Deku. You've been a very good boy."

Slowly, Deku's eyes seemed to refocus on the world around him, eventually falling on Katsuki. "Kacchan…" the buzzed greenette said fondly. This time, though, unlike this morning, there was no bold defiance in his eyes. No grimace on his face. Only love and adoration.

That sight alone was almost enough to bring Katsuki to an orgasm right then and there.

He needed to test a few things, though. "So, can you tell me who you are?"

"I'm Deku, of course." He spoke with a tone of disbelief at the question, as if the answer was the most obvious thing in the world. He really needed to push though, to make sure this worked.

"You aren't Izuku Midoriya?"

His head tilted to the side, like a confused puppy. "No. Who's that, Kacchan? Is he another slave of yours? I'm better than him! Kacchan doesn't need any slaves besides Deku!" He sounded almost desperate, the taste of jealousy dripping from his words at the thought of someone else getting his Kacchan's attention.

Katsuki laughed dismissively and rubbed on the soft green fuzz on top of Deku's head. "It's okay, Deku. He used to be my slave, but you're so much better. You're a good boy for Kacchan, right?"

"Yes Kacchan! I'll always be a good boy for you! I love you!"

Katsuki stared deep into Deku's eyes, but didn't see a hint of lies or defiance. It seemed he'd finally broken the nerd down. At long last. He gripped Deku's chin and pulled him into a lust-fuelled and tongue-filled kiss. He made out with his newly broken slave for a full minute before pulling away with a contented sigh, Deku whining at the loss of his Kacchan's touch.

"I love you too, Deku. Now come on, let's go to my chambers and we'll have some food and a bath, okay?"

"Okay Kacchan! That sounds great!" That radiant smile was still there on Deku's face, lasting all the way since their childhood.

"Just remember, Deku, when we're in front of others you will call me Master, alright?"

"Yes Master! I remember!"

"Good boy." He gave his fuzzy head another rub before removing his restraints and pulling him into his arms, bridal style, and began carrying him towards his room.

His time in captivity had caused some of the nerd's muscle definition to fade, but he would still need some time before he lost it all.

Katsuki was eager for that day. He didn't want the hero Deku that his friend had become, he wanted the weak Deku that he remembered from middle school. The small, lithe boy that he'd first become obsessed with.

He could be patient though. The hard part was done, Deku's mind seemed completely broken, so it was just a matter of time before he shaped his body into what he wanted as well.

Until then, Katsuki would be sure to have lots of fun with his new slave.

Eijirou deposited the unconscious body of the guard he'd just taken out into a nearby broom closet and then made his way through the villain compound, slinking from shadow to shadow. So far, the intel they'd received from their anonymous mole had been right on the money.

It was almost three months to the day since Izuku, aka Number One Hero Deku, had gone missing, seemingly captured during a failed mission to take out the League of Villains and capture their former-classmate-turned-villain Katsuki Bakugou, aka Ground Zero.

Eijirou had pretty much been a total wreck every day since he'd heard the news. Sure, the two of them had never gotten around to dating or anything, Eijirou hadn't even mustered up the courage to confess his feelings yet, but it didn't change the fact that he was pretty much head over heels for the green haired hero.

Two weeks after Izuku's disappearance, they started to receive anonymous intel from someone claiming to be a member of the League of Villains. They'd claimed to have finally seen enough of what they were doing and wanted to help put a stop to it by leaking information to the heroes to help take the League down.

It had started out small: info that led to the capture of a number of lower tier thugs, something to prove the person was on the level. Over time, however, it got bigger and bigger, leading to more mid-tier villains, people who'd done some bad things to good people. None of it had been huge, however, until two weeks ago, when their anonymous mole had given them intel that led to their biggest achievement to date: Tomura Shigaraki was now dead.

The intention hadn't been for him to die, of course. Kaminari had led the mission with the hope of taking him alive for interrogation, but when push came to shove, he'd been forced to choose between killing the villain or letting him kill a building full of innocent civilians. Eijirou didn't envy that choice, but he's sure he would've made the same call.

The League was slowly beginning to crumble, and now only Bakugou was left in charge, which meant that he was the one who had Izuku held captive now. Assuming, of course, that Izuku was still alive.

Eijirou shook those thoughts from his head. He couldn't let himself think that way. Izuku was alive. His former best friend may have turned into a ruthless villain, but Eijirou still wouldn't believe that the blonde would ever kill his childhood best friend.

And if their mole was to be believed, Eijirou was now making his way through the very compound where Izuku was being held. He'd been hoping to get this information as soon as their inside man's information had started checking out, but he hadn't dared to hope.

The moment it came in, though, he'd demanded to be the one sent on the mission. His superiors had been hesitant, wanting to send someone with a more stealthy Quirk, but thank the gods for his bro Kaminari. He'd really stepped up to bat and convinced them that there was no one better suited for this mission than the Sturdy Hero: Red Riot.

The mission had been going perfectly so far. He'd discovered the hidden side entrance deep in the forest, the access code provided had worked perfectly without setting off any alarms, and he'd managed to silently choke out the one guard stationed near the entrance.

He was currently following the map to Izuku's cell that he'd spent the last two days memorizing. He was never the best at study and memorization, but this was for Izuku, and for Izuku he would do anything.

He avoided the attention of a pair of patrolling guards and then finally made it to the steel reinforced door that should be where Izuku was being held. Taking a deep breath to calm himself and prepare himself for anything, he punched in the keycode to the access pad by the door. There was a soft beep accompanied by the hiss of the door sliding open.

The sight on the other side sent shivers down his spine.

It was unmistakably Izuku, but he looked so different. He was slumped against the far wall, his arms held above him by chains attached to what looked to be Quirk-cancelling cuffs. His head was almost completely shaved, only the thinnest layer of green fuzz still showing. He was also completely naked, a sight that normally would've made Eijirou blush if it weren't for the rage he was feeling at whoever had done this to Izuku.

Stepping into the room and examining further, he saw that Izuku was also much thinner than he had been before his capture. He was a fine specimen of a hero before, sporting almost as much muscle and definition as Eijirou himself, but now it was almost entirely gone. He'd seen a few pictures on social media of Izuku in his middle school days, small and scrawny with almost no muscles or definition at all, and it wasn't terribly far off from how he looked now. He wasn't malnourished, so they'd clearly been feeding him, but they obviously hadn't been giving him enough calories or physical activity to keep his muscles from shrinking away almost completely.

Most alarming, however, was the small green plastic cage that was affixed to Izuku's cock and the creamy looking white fluid that was laying on parts of his skin and pooling on the floor beneath him. Further, Izuku's eyes were open but didn't seem to be focused on anything. He didn't even seem to have registered that Eijirou was here or had entered the room.

It was immediately clear to him what the villains had been doing to Izuku all this time and he was suddenly more enraged than he'd ever been in his entire life. He squeezed his eyes shut for a moment and took a deep breath to try to calm down. He couldn't let his emotions take over right now, he had to keep a level head so that he could get Izuku out of this.

He reached up to grab the Quirk cancelling cuffs and activated his own Quirk in his hands to squeeze and shatter them to pieces, catching Izuku in his arms to keep him from falling. He pulled him in close and gently stroked his cheek to try to get his attention. "Izuku. Izuku, hey, it's me. It's Eijirou."

Izuku blinked several times in rapid succession before his eyes fell onto Eijirou's face. He squinted and his eyes tilted in confusion, like he was struggling to grasp the situation before finally something cleared a little in his emerald green eyes. "Ei-chan?"

Eijirou smiled wide at finally hearing Izuku's voice for the first time in months and hearing that sweet nickname too. He struggled to hold back tears of joy. "Yeah. Yeah, Izuku, it's me." There was a brief flash of...something whenever he said Izuku's name but he chose to ignore it for now. "I'm here to get you out of here."

"Red Riot. Come in. Status Report." The voice in his ear piece spoke.

"Hold on just a sec, Zuku." He pressed a finger to his earpiece to activate the transmit function. "Red Riot here. Package acquired. He's in rough shape, but he's alive. Moving to extraction now."

"Excellent news, Red Riot. Keep us updated of any developments, otherwise we'll see you both soon."

Izuku reached up and grabbed his arm with a sudden urgency. "Wait! We can't leave yet!"

Eijirou was confused and communicated such with his face as he looked down at Izuku. "Why?"

Izuku seemed to hesitate for just a moment, like he was struggling to remember something, before whatever it was finally clicked in his brain, and he spoke very fast, without taking a breath. "There are other heroes here, we have to save them too. I know where they're being held and I can take you to them!" If Eijirou didn't know any better, he'd think the line was almost rehearsed, but he wrote it off as just side effects of the hell Izuku had no doubt been through the last three months.

"Alright, Izuku," another flash of whatever it was when he said his name, "We'll save them. I promise." He held his finger to the transmit button again. "Come in, Control. Red Riot here. Change of plans. Package informs me there are other hero captives present in the facility. Redirecting to retrieve them before moving to extraction."

There was a brief pause before the response. "Copy that, Red Riot. Deviation approved, just be careful. We don't have intel on the entire facility from our mole, just the parts you've been navigating. If it seems like too much, just abort and get out of there with the package."

"Copy that, Control. Red Riot, out." He smiled down at Izuku again. "Alright, let's go rescue those heroes. Do you think you can use your Quirk if we need to?"

"I don't think so." He looked down at his own body, now thin and lithe. "I don't think I have the strength to support it now. I'm sorry, Ei-chan."

"That's ok, Zuku. It'll be alright. I'm gonna get you out of here, I promise." He helped move the two of them to their feet, and much to his surprise, Izuku was able to stand and walk on his own without any issue. "I'm sorry, I don't have anything for you to wear, but I can at least do this."

He reached down and gripped the bit of the plastic cage that was securing itself around Izuku's cock and activated his Quirk, destroying the plastic and letting the pieces fall to the floor. His cock was honestly quite small, but Eijirou already knew this from seeing him in the locker rooms at the agency.

It didn't matter to him, though. He liked Izuku for who he was as a person. Besides, in his darker fantasies, he'd always been more preoccupied with the greenette's plump and fat ass being wrapped around his cock, which was plenty big enough to satisfy the handful of partners he'd been with.

Izuku flinched and grimaced as the cage fell away, but Eijirou interpreted it as pain. "Oh, sorry! Did I hurt you?"

Izuku recovered quickly and waved his arms in front of himself. "N-no! Not at all! You just...caught me off guard, that's all!"

God did he miss this sweet awkward side of Izuku. So much so, that he was distracted and failed to notice that Izuku grimaced down in shame at his now uncaged cock when Eijirou turned around back towards the door. "Let's get moving, Izuku. Are the other heroes far?"

"N-no. Not far at all. Here, follow me."

Together they crept through the facility, surprisingly not running into any other guards as they went. Eijirou tried very hard not to be distracted by the gorgeous ass that was slightly bent over in front of him as they crouched low to stay out of sight, but he could feel his cock twitching from the dirty thoughts creeping at the edges of his mind.

Fortunately, it wasn't long before they arrived at another door, much like the one they'd just left. "Here. We're supposed to go in here," Izuku said as he punched in a code to the keypad, causing the door to slide open, revealing a pitch black room beyond.

"Supposed to go? What do you mean?" Eijirou asked, confused. "And how did you know the code to the door?"

"I-I saw one of the g-guards punch it in the other day," Izuku stammered, ignoring the first part of the question. "Come on, the heroes are in here."

Eijirou was concerned, but decided to trust his friend and crush anyways, stepping into the dark room behind Izuku. This turned out to be the wrong decision, however, as the door suddenly slammed shut behind them, leaving them in pitch blackness. "Izuku? What's going on?"

"I did as you asked, Master!" Izuku shouted into the darkness, but to who? What the fuck was going on? "Was I a good boy?"

Just as his eyes were beginning to adjust to the darkness, a brilliantly bright light flashed on, blinding him temporarily. He activated his Quirk on his entire body, going full Unbreakable out of survival instinct and assuming a combat stance as he rapidly blinked his eyes trying to get them to adjust.

He held his fingers to the transmit button on his earpiece. "Control! Come in, Control! We've been made, send in backup!" A long pause of silence and static before a voice spoke from in front of him. A painfully familiar voice.

"Poor Red Riot. Still sporting that shitty hairdo, I see. Well, that's fine. We'll do something about that soon enough. I'm afraid backup isn't coming. You see, you're all alone out here."

"Bakugou, you son of a bitch! What did you do with Izuku?!"

"That's not my NAME!" He heard Izuku scream before there was the sound and feeling of something clicking around his wrists and he felt his Quirk fall away. He tried to reactivate it, but it didn't respond to his command at all anymore.

He finally managed to blink away the temporary blindness from the light to see confirmation of what he'd feared: Quirk cancelling cuffs had been slapped onto his wrists, and it seemed like Izuku was the one who put them there.

"Izuku, what the hell? What are you doing?" Eijirou asked, feelings of betrayal beginning to creep into his heart.

"Stop CALLING ME THAT!" He screamed at Eijirou. "My name is DEKU! Not Izuku ." He said the name with disgust, like it physically pained him to say it or even hear it.

"Like what I've done with him? It took a long time, but he's finally become such a good boy, don't you think?" Katsuki's voice spoke over the speaker system in the completely empty concrete room. Izuku was standing several feet away from him and looking up towards the sourceless voice.

"Master! I did what you asked! I'm so sorry about my cage! The bad man broke it; I didn't want him to! Please forgive me!" His voice sounded so broken and desperate, like there was nothing more important in Izuku's entire world than pleasing Katsuki.

"It's okay, Deku. I saw the whole thing, I know it wasn't your fault." Katsuki's voice disgusted Eijirou. It was dripping with false empathy and understanding, designed purely to give Izuku what he wanted and put him further under Katsuki's thumb.

"You're sick, Katsuki! How could you do this to him? He was your best friend once!"

"You're damn right! He was mine, always was, so now I've claimed him. He's mine, and soon you will be too, best bud ."

"You'll never get away with this, Katsuki! The heroes know where this base is, and if I don't check in soon, they'll swarm this base with every hero they've got!"

Katsuki's voice chuckled. "Is that so?" There was a small sputter of static before suddenly he heard the familiar voice of the control room over the loudspeaker. "Copy that, Red Riot. Deviation approved, just be careful." The voice then laughed, but halfway through there was a blast of static and the laugh changed to Katsuki's unmistakable cackle.

"It was me, you fucking moron! I've been the voice in your ear this whole mission, and I've been your super secret mole!"

Eijirou was floored. There was no way. "No, that's impossible. We caught a bunch of your men, even high ranking ones! And the mole's intel got Shigaraki killed!"

He just laughed again, even harder this time. "Yeah, exactly! With Shigaraki gone, there's no one left to run the League but me . And all those goons you captured were the ones most likely to stay loyal to him. You were just taking out my trash!" He busted out into laughter, the kind that was drenched in the joy of another's suffering.

"You're sick. I can't believe I was ever friends with you."

The laughter petered out into a mildly annoyed sigh. "Alright, enough of this. Time to get down to business. Deku, you know what to do."

"Yes, Master!"

Suddenly, Izuku was coming towards him holding some kind of small canister that had been lying on the ground unnoticed by Eijirou until now. He put up his arms in a defensive stance, trying to activate his Quirk out of habit, even though he knew it was pointless with the cuffs in place.

"Don't do this, Izuku. Please, I don't wanna hurt you." His voice was almost breaking from the pain of the reality of the situation.

"I told you, my name is DEKU!" He shouted as he skidded to a stop still a few feet away and flung the canister directly at him.

Eijirou caught it out of the air, hoping it wasn't some kind of grenade, but before he could even begin to examine it, a blast of some kind of gas shot out of one end directly into his face.

He coughed and sputtered, dropping the canister to the ground and inadvertently inhaling large amounts of whatever it was.

"You really are a moron, ya know that?" Katsuki spoke as whatever was in that gas raced through Eijirou's system. He could already feel his body heating up. "Oh well, you'll still be the perfect test subject for the new strain."

Eijirou continued to cough, but managed to stammer out a reply. "T-test subject? For wh-what?"

"Our aphrodisiac of course," Katsuki said matter-of-factly, "The version we've had out on the market makes the user a mewling slut, desperate to get fucked. It's quite popular, we even use it ourselves to break in new slaves. I used it to help train Deku, in fact."

Eijirou felt himself growl in rage at the comment, shocking even himself a little.

"This new strain, though, is an attempt to approach things from the other side. If it works, it's supposed to increase aggression in the user and make them desperate to fuck anything that moves. You're the first human trial, though, so this should be interesting. Especially since you're already hard as a rock, no pun intended." He chuckled at his own joke.

Eijirou looked down and saw that his cock was indeed harder than it had been in a long time, practically tearing the lower part of his hero costume from the strain. He felt the heat building in his body, focused heavily around his cock and felt the overwhelming urge to free it from it's confines. He also felt his breathing getting heavier and his mind getting foggier.

"Hmm, looks like it's going into effect way faster than anticipated. May have to adjust the chemical makeup just a bit." Katsuki's voice muttered, seemingly more to himself than anything.

Eijirou was finding it harder and harder to focus. His cock felt like it was on fire and it was straining to be free, the tightness of his pants and underwear becoming painful. He couldn't take it anymore, he had to be free.

He cried out with a deep near-growl as he used his strength to rip the lower part of his costume away, letting his rock hard cock spring free into the cool air, bringing just a little relief, though only a little. It was still coursing with heat, and seemed...bigger than he remembered.

"Huh. Well, that's unexpected." Katsuki muttered as Eijirou's eyes went wide. His cock, which was a very respectable 6.5 inches before, was now growing before his very eyes, adding what looked like about 2 full inches in length and quite a bit in girth. Then there was a tightness and heat from the base of his cock, so intense that it was nearing excruciating.

Once he could finally focus enough, he looked down and saw that his cock had grown a large bulbous growth right at the base, almost like the knot of a canine cock.

"Damn, I knew it was risky to use that Wolf-Quirk blood. Oh well, this is what testing is for. Deku, go ahead and put the collar on him before he gets too aggressive."

"Yes, Master!" Izuku retrieved a collar from a hidden cubby hole in the wall and walked over to Eijirou, who was still breathing heavily and trying to focus his mind, which felt like it was swimming through a boiling lake of thick steam and fog.

There was a sudden click as a large metal and leather collar was secured around his neck, and in that moment Eijirou lost all sense of self-control.

His hand flew up to grab Izuku by the throat as he growled, his cock painfully hard and desperate for release.

"Fuck," Katsuki swore, though more out of frustration and annoyance than out of any real concern, "This strain is way too powerful. Gonna need the docs to tune it WAY down. Oh well, might as well see the test to the end. Deku, be a good boy and submit to Red Riot here, okay? I'll reward you after, if you're a very good boy."

Izuku managed to cough and choke out a "Yes Master" before Eijirou grinned and threw him to the ground.

"Eiji…" Katsuki spoke sternly, and Eijirou perked his ears up as he grinned hungrily down at the small green-haired man. "That collar has heavy sedatives in it as well as a shock function, so if you hurt Deku too bad, you'll be punished, got that?"

Eijirou growled towards the voice but nodded. A deep part of his rational brain was screaming at him to stop, that this was wrong, that he was about to force himself on the most amazing man he'd ever met, but whatever this drug was, it was too powerful. He had no control over his urges as he dove down onto Izuku's small, lithe frame biting and licking at every inch of flesh as he rutted his extremely hard dick against the other man's soft, scarred skin.

The small cubby hole opened again and a bottle of lube rolled out of it, coming to a stop against Eijirou's leg. He snatched it up and immediately coated his newly engorged cock in it, similarly lathering up Izuku's hole, which already seemed well-prepped.

"Hands and knees," Eijirou growled out, watching shivers run down Izuku's spine, whether out of fear, suspense, pleasure, he didn't know and didn't care. He only cared that Izuku moved into position, down on his hands and knees with his back arched and his fat, round ass pushed out towards Eijirou.

He wasted no time, grabbing Izuku's hips with both hands and pressing his cock against his hole, spearing him with almost his entire length in one go. Izuku cried out in pure pleasure as the thick cock slammed into his prostate, and Eijirou felt supremely satisfied to be buried in the tight warmth of the smaller man's ass.

The haze and fog around his mind grew thicker, all thoughts pushed out besides fucking the ever-loving shit out of the ass in front of him, and so that's what he did. He pulled nearly all the way out and then slammed his cock all the way back in, fucking him over and over with everything but the knot.

The pleasure was overwhelming, the greatest thing he'd ever experienced, and Izuku seemed to feel similarly, if his moans and screams were anything to go by. "Yes! Yes, Ei-chan! Fuck me! Fuck my ass! It feels so good, Ei-chan!"

That nickname seemed to cut through the fog for just a moment, giving the last rational part of Eijirou's brain a clear look at just what he was doing. It flooded him with guilt to be taking advantage of his close friend and crush like this, but he couldn't stop. It felt too good to stop, so he didn't. He let go and let the drug that was flooding his system carry him away as he slammed over and over into Izuku's wrecked hole.

He could hear the sound of Katsuki's voice making comments of some kind, but he couldn't focus on them, couldn't understand them.

He was so far gone in the drugs and the pleasure that he was starting to forget his own name, Izuku's name, or anything about his life. He felt like an animal and was acting like an animal. All there was was the pleasure of fucking the ass in front of him.

He felt his climax building and began pushing in hard, trying to force the knot deep inside Izuku's ass. The smaller man was screaming, though he wasn't sure if it was out of pain, pleasure, or both, but it didn't matter. He couldn't've stopped him.

After a few more hard thrusts, there was a loud pop as Izuku's hole stretched loud enough to take the entire knot, leaving Eijirou firmly locked in place inside the hole. He screamed out a primal roar of pleasure as he unloaded blast after blast of cum inside Izuku's ass.

After what was likely just a minute or two, but felt like an eternity, his orgasm finally subsided, but he didn't have time to process anything after that as he felt a sharp prick in his neck, and then blackness quickly overtook him.

Katsuki let out a sigh as he watched on the monitors as Eijirou fell to the ground, knocked out cold by the sedative in his collar. Deku, for his part, seemed to still be conscious, but was sprawled out on the ground, still tied to Eijirou by the knot that had formed on the red-head's cock.

"Take these notes back to the docs and have them work up a new formula. As interesting as this was, we can't exactly market it." He chuckled as he handed off his notes to one of his goons who nodded and rushed off with them.

"We can test a few more variations on Eiji," he muttered to himself, "but it's probably gonna break his brain before too long."

He chewed at his lower lip in thought before shrugging. "Oh well, not like he was important. Denki'd probably love to have a meathead like Eiji to play with when I'm done anyway."

Katsuki stood up from his chair and headed off to go retrieve Deku to get him cleaned up and rewarded for such a good job. He'd have to get him a new cage, since Eiji had so rudely destroyed the first one, but that was easy enough to do.

"Almost done now. Very soon, I'll have the last thing I need, and then no fucking heroes will ever be able to stop me."
