The average human body has about five liters of blood.

Those with mutant-type quirks and atypical bodies can have drastically more or less, but for someone like Katsuki, the standard amount applies.

It’s something he’s made vividly aware of as the needle and tubing in his arm begin to reduce that number. 

He’s made aware of this because the person that’s taking it won’t fucking shut up about it.

“I’m just having a tiny taste for now, Katsuki-kun,” Toga purrs, stroking her fingers along the red line of plastic. “I can only take about a liter and a half before you’ll go into shock. It’s really not fair, you know. Five whole liters in here, and you only want to give me one? Stingy.”

“Sucks for you,” Katsuki says. He isn’t particularly interested in pleasant small talk, what with being shackled to a fucked up medical chair in some dingy basement cell. Three bare walls have no windows—not even one in the door—and the fourth is covered by a thick curtain.

A bead of sweat rolls down the side of his face.

This is… bad. He’s been in almost this same stupid situation before, captured by the League and chained to a chair with his quirk locked away with his hands in thick metal casings. And he got out of that, didn’t he?

Except, he didn’t. He was rescued—by All Might and a bunch of other heroes.

Plus Deku and his other stupid friends.

Katsuki isn’t so sure he’ll be as lucky this time.

Toga giggles, capping the vial of blood and closing the line. She waggles it in Katsuki’s face; the dark red liquid gleams as it catches the light from the naked bulb above them. “Don’t be rude to me when I’m being so nice. I could just take all of it. I bet mommy and daddy would love a visit from their brat of a son that never visits.”

The image of his parents welcoming Katsuki into their home, only to wind up slaughtered by his own hands, is impossible to avoid.

“Ahh?” Katsuki barks, clenching his fists inside their prisons. “Be my guest. Old hag will probably smack the shit out of you.”

Pouting, Toga places the vial onto a tray next to Katsuki. “Well, that’s no fun.”

Katsuki tries to not look too visibly relieved; goading her is a gamble, but begging her to leave his parents alone won’t save them either.

“Oh, but you know what would be fun?” she asks—rhetorically, surely—while clapping her hands. “Let’s play a game!” Before Katsuki can express his disinterest, Toga reaches into a pocket and pulls out another vial. It looks much the same as the first, but the color of the stopper is white instead of black.

She grins, and the light reflects off of her glistening canines.

“Whose blood is this?”

Whose—

“…What?” Katsuki rasps.

“Whose blood is this?” Toga repeats, pushing the warm glass into Katsuki’s cheek. “If you guess right, I’ll let you both go! But, ah! Don’t be hasty, you only get one chance. If you get it wrong…” she hums and her eyes darken, saying, “I’ll go take all five liters.”

The average human body only has about five liters of blood.

So they’re probably human without a mutant quirk—which doesn’t really narrow it down.

“Gonna give me a hint?” Katsuki asks.

“Nope!” Toga says cheerfully. “If you don’t want to guess, I can take another serving of your blood instead.”

Fuck. Katsuki has no idea who it is with any certainty—he has a hunch, but it’s not worth risking the other person’s life if Toga is really serious about killing them on a wrong answer. She might still kill them both anyway.

“Fine, take it,” Katsuki mutters.

Toga claps her hands again, practically squealing with delight as she pulls out yet another vial and taps Katsuki’s line with it. The way she watches the glass fill with red liquid is borderline obscene: her eyes are lidded, her face is flushed a rosy hue and her breathing is far too heavy. It’s fucking disgusting, but Katsuki would rather she act like that about his blood and not the rest of him. He’s seen how she acts around Deku.

If he’s—

“All done!” Toga chirps. The vial is disconnected and sealed, tucked away in her sweater just like the others. “I’m gonna go pay our sweet little friend a visit, and see what he thinks!”

He. Again, doesn’t really narrow it down.

Nor does it rule out the hunch.

She flounces out of the room, leaving Katsuki to stew in his seat.

He tests his bonds again, pulling at his wrists until they feel like they’ll dislocate if he yanks any harder. If he can’t free himself, he’s probably fucked. Two vials of blood taken isn’t going to affect him much, but he imagines it’s not going to stop with just that. She certainly doesn’t seem like the type to follow the recommended limits.

Fuck. How could he have been so careless? Katsuki couldn’t even say he was brought down in battle, after a long and brutal struggle. Beaten down over time and against overwhelming odds, where he held out longer than most would have. Only succumbing after a top villain—no, an army of villains—wrestled Katsuki into forced and valiantly resisted submission.

No, Katsuki got hoodwinked by some extra on the street asking for directions.

He doesn’t remember anything else.

And now it isn’t even just Katsuki. At least one other person that he presumably knows is allegedly in this mess with him, which makes it seem like an even more egregious failure. Katsuki wasn’t with anyone; he was just going to the fucking pharmacy to restock on bandages and painkillers. Mundane, boring. So who else got nabbed with him?

“You know, I’m not surprised he picked the same option, he’s just selfless like that,” Toga says with a sigh as she waltzes into Katsuki’s cell. She’s back sooner than he thought she’d be, and the words on her thin lips only increase the likelihood of his hunch. “I love him, you know? Do you love him, too?”

Katsuki feels his heart thump loudly in his veins. He can’t blame it on blood loss.

Or the fact that she’s entirely naked.

Is it a trap? Is she setting him up to make him say the wrong guess, and condemn this other person to death by exsanguination?

“I just, ah… couldn’t help myself,” she says, running her hands down her face as it melts into someone else’s under a waterfall of gray sludge. Slender limbs thicken and straw-like hair darkens and curls. Her fangs disappear but the rapturous smile left behind is completely out of place under round, freckled cheeks and bright green eyes.

“Deku,” Katsuki breathes.

She’s even wearing his clothes. How does she get that from blood?

The stolen face grins. “Correct.”

Katsuki swallows. “So that’s it? You let us go?”

“Aw, Kacchan,” Toga says, in a startlingly perfect imitation of Deku’s voice. It sends a shiver down Katsuki’s spine. “You already had your chance to guess. You gave it up to save my life! Now we play a different game.”

The shout catches and chokes in Katsuki’s throat as Deku’s body straddles his lap, pressing their crotches together. Katsuki tries to shift away but he’s stuck, and it’s immediately and distressingly apparent that Toga’s transformation is top to bottom: there’s a hard erection pressing against Katsuki’s soft dick.

“Kacchan,” Deku’s voice whispers, moans, in Katsuki’s ear. “Do you like me better like this? Would Izuku-kun like me better like you?” She licks along Katsuki’s jaw, thrusting her hips forward deliberately. 

“Get the fuck off me,” Katsuki snaps, twisting his head away from that fucking face that looks just like Deku but is stretched so grotesquely that no sane person could ever confuse the two. He can’t move his lower half at all, can’t escape from the humping he’s being subjected to. Katsuki’s own cock remains stubbornly dormant because fuck you.

“You’re really a lot less fun than Izuku-kun,” Toga pouts. It’s a ridiculous expression on Deku’s face with his lips pushed forward like a petulant child, batting his eyelashes like a woman. Deku would never. “But that’s okay. Here’s your second choice: I’ll put the blood back, if you give me twice as much.” Her fingers trail down Katsuki’s chest until they begin to make playful circles around his nipples.

Katsuki sucks in air through his teeth. Toga’s definition of play has turned overtly sexual since she transformed into Deku, but it still doesn’t really seem like she’s that serious about it. She’s just fucking with him, not actually going to fuck him.

It’s still fucking annoying.

“How you gonna put it back when you’ve already drank it?” Katsuki asks, part to distract himself from what’s sitting in his lap and part just because it’s a logical question to pose.

Toga grins and it still looks so out of place on Deku’s face. “I’ll give him your blood, silly!”

Katsuki feels faint. They have… incompatible blood types in that direction; Deku can donate to Katsuki, but Katsuki’s type A blood can’t go in reverse. “No,” he says, his voice thick. “I choose no.”

Deku’s fingers run through Katuski’s hair like they belong there, scratching across his scalp in practiced rows. Katsuki hates it but mostly hates that he yearns for it, that he has to resist and fight against the sensation when his mind knows it’s just a fake.

“But, Kacchan, I’ve already lost so much blood, surely some is better than none?”

The muscles in Katsuki’s abdomen contract. He’s not sure if it’s a sickness he feels or some purely physical response to Toga continually grinding against him. Fuck! Think, damnit! “You want him to die?” he hisses. He’s no doctor but getting the wrong blood type has to be worse than losing blood, assuming Deku hasn’t been bled past the liter and a half mark yet.

She groans and humps forward again, and Katsuki flinches at the responding tingle between his legs. Fuck. He’s only human, getting enough stimulation is going to cause some kind of reaction eventually even if he’s not into it. It doesn’t help that it’s literally Deku’s body sitting in his lap. He needs to get her to back the fuck off, now.

“You’re the blood expert, ainchta?” Katsuki snarls. “You’re smarter than this. Should know he can’t take my type.”

“Ohh, Kacchan, you know just what to say to me,” Toga purrs, grabbing her dick through Deku’s shorts with one hand and squeezing Deku’s—her—chest with the other one.

Katsuki wrinkles his nose in disgust. It’s not Deku, it’s not. But, shit, it’s still Deku’s body gyrating on top of him, something he never could have imagined in his wildest dreams. No, Deku is shy and sweet even if he’s full of fire, and maybe in some distant and unattainable future Katsuki could have laid with him in white linens and their bodies would have come together in a crash of tears and ecstasy. Not like this. Maybe not anything like that, but certainly nothing like this.

“Mmn, okay, Kacchan.” Stop saying that. Stop saying that. “I have another proposal. I’m going to take your blood. I can either play with it before I give it to him, or use the blood to play with him. As you.”

Play with it??

If by play with him Toga means doing to Deku what she’s currently doing to Katsuki… well, fuck, Katsuki doesn’t want that either, but it’s better than sending him into some kind of shock because he’s been injected with the wrong blood type, or blood that’s been contaminated. “I said what I said, don’t give him my blood,” Katsuki says. He tries to twist away from Toga’s pawing, but there’s nowhere for him to go. He bites back a gasp as she bites at his neck, sinking teeth that he expects to be fangs into the soft skin under his jawline.

She giggles and pushes off of Katsuki’s lap with a hop. It’s disconcerting, eerie, to see Deku glaring down at him and sporting an obvious boner in his sport shorts. Katsuki tries not to look at it. “Goodie, I was hoping you’d pick that.” 

She reaches across him and picks up the black-capped vial of Katsuki’s own blood. She unstoppers it and knocks it back, letting the blood dribble across her lips and down Deku’s chin. It’s wasteful, but Katsui supposes she isn’t too concerned when the source is sitting right in front of her.

Even if he only has about a liter left to give.

Deku’s skin sloughs off of his bones, followed by the bones themselves, until they’re replaced by a higher cut of cheekbone and a fairer complexion of skin. It’s just like looking into a mirror. Katsuki watches himself stand upright, several inches taller now, and smirk. His hands traverse his body, feeling up larger muscles and a broader frame. Toga palms at her cock and moans appreciatively, giving Katsuki a knowing look that he refuses to meet, dropping his eyes to the floor.

“Fuck, now this is a cock,” Toga growls in his deep timbre, and it’s like listening to a recording of himself. “Can’t wait to stick it in Izuku-kun.”

Wh—

Katsuki jolts against his binds, lurching forward and forcing the chair to rattle in its bolts. “You—” he starts, unsure of exactly what to say. “You can’t!” he lands on. What the fuck!?

“Aw, sure I can, nerd,” Toga says with a cackle, with Katsuki’s voice, running her tongue across borrowed canines. “Don’t worry. I’ll tell you all about it.” She lets her eyes flutter shut, squeezing herself through Katsuki’s sweats. “Izuku-kun will finally want me,” she sighs. Her eyes snap open, pinning Katsuki with his own glare. “Because I know how much he wants you.”    

Stunned, Katsuki’s mouth hangs on nothing as Toga taps his line. She begins to draw more blood out of him to replace what she just imbibed. “You know, something you might not know about me, but I can change someone’s blood type after I’ve drawn it.”

Katsuki blinks. “What?”

Toga giggles, a disconcerting sound that Katsuki has never heard come out of his own mouth. It sounds like he’s dying.

“You think blood type is going to be a limiting factor for me? Who do you take me for, Stainy?”

She’s really fucking with him now. “Then give him my blood, if you can convert it!”

“Nooo, you already made your choice, no take-backs! But, I’ll give you a present for free,” Toga says as she finishes taking two vials of blood and pockets them. How much blood in each vial? How much has Katsuki lost already? He doesn’t think it’s more than what’s taken during routine testing, but he also doesn’t think she intends to stop here.

With a flourish, Toga yanks open the curtains across from Katsuki’s seat. The shower of dust reveals not quite a window but instead a pane of glass that looks into another cell much like the one they’re in. He’d assume it was a literal mirror if not for the difference of who’s strapped to the other medical chair.

It’s Deku.

He’s awake and looking forward, but he makes no movement or gives any sign of recognition. It doesn’t seem like he can see Katsuki at all. A two-way mirror, then?  

“You can watch! Boop!” Toga chirps as she pokes Katsuki’s nose with a bloody finger.

She’s halfway to the door before Katsuki jolts, the realization of what’s about to happen crashing down on him. “Don’t you dare!” he shouts. “Fucking—What do you want?! More blood?”

“Eventually,” she says brightly, before closing the door behind her.

It’s just a few moments of awful silence before she reappears on the other side of the glass in Katsuki’s body.

“Kacchan?”

Katsuki’s heart squeezes. Deku’s voice sounds tinny, like it’s coming in over a speaker. Katsuki shouts, screams in response, but Deku remains looking at the copycat. The rooms, even the glass, must be sound-proofed somehow; this was all planned to go exactly like this.

These sick fucks.

“Yeah, I’m getting you out of here, hang tight,” Toga says as she rushes over to Deku, making a show of checking over the restraints before maneuvering behind him. She looks directly through the glass to make eye contact with Katsuki and grins.

“It’s not just me, Kacchan, they have someone else down here. Is the villain still a threat?”

Is the villain still—Does Deku not know it’s Toga?

“No, I took care of him. And I was the other person, they had me locked up. But they did a shitty job, and I got free and knocked them out.”

Deku visibly relaxes, completely unaware of what really looms behind him. “Ah, thank goodness. Kacchan’s amazing. I haven’t been able to break—”

Toga puts a hand in Deku’s hair, leaning down to inhale directly against his scalp. Her eyes roll back in an ecstasy that looks gross on Katsuki’s face.

“Um. Kacchan?”

“Just had to reach this,” Toga says as the chair suddenly reclines, tipping Deku back until he’s almost horizontal. “It’s dumb but it’s the only way to disengage the cuffs.” She comes around to stand by Deku’s feet, shooting Katsuki another look through the mirror. He yanks at his own restraints in response.

“O-oh, uh, um,” Deku stammers as Toga flips another setting on the chair that raises and spreads his legs apart. She smoothly steps between them until Deku is almost entirely blocked from view by Katsuki’s body.

“No, that won’t do,” Toga mutters after checking the mirror over her shoulder. Another button press rotates the entire chair forty-five degrees and gives Katsuki a much worse view where he can see everything. “There we go!”

“K-Kacchan, what are you…” Deku trails off, his face paling as Toga thrusts her hips forward in much the same fashion as she was doing to Katsuki before, grinding her visible erection into the space between Deku’s spread legs.

Katsuki can’t watch this. It’s so much worse than Toga doing it to him, where he knew it was her from the start. That this is happening to Deku when he thinks it’s actually Katsuki? He squeezes his eyes shut for a moment before forcing them back open. No. He has to watch, as fucked up as it is, as much as they want him to. All Katsuki has right now, the only tool in his arsenal, is observation.

“Kacchan, s-stop! What’s going on, did they drug you? Is it a quirk?” Deku twists and squirms but he’s as stuck as Katsuki was.

It’s only a small comfort that Deku thinks this is out of character.

“Yeah, something like that,” Toga growls. Her hands feel up his chest  as she continues to grind against him.

“O-okay, Kacchan, you need to listen to me, this isn’t you,” Deku babbles, his words rushed and slightly panicked. Well, he’s not wrong. “Y-you don’t want to do this, okay? Kacchan!”

A huff belies Toga’s frustration. “Come on, Izuku-kun, don’t you want to tell me how amazing I am?”

Deku’s eyes widen, and well, at least Toga didn’t work very hard to keep up the charade.

“Toga,” he breathes.

She stills for a moment. “Oops! Well, guess the gig’s up. Hey, didn’t I tell you to call me Himiko-chan? But, you can call me Kacchan right now, I don’t mind,” she purrs, using Katsuki’s body to sandwich Deku against the chair.

“What did you do to him? He’s here, isn’t he?” Deku growls, seemingly unconcerned with the threat in his lap when someone else might be in trouble. This fucker.

“Oh, yes. I keep taking his blood. It’s too spicy though, not sweet like yours, yum,” she says as she nuzzles against Deku’s neck. It’s Katsuki’s face doing it, and it makes him feel sick to watch. “But I won’t take more than I need if you let me fuck you.”

Katsuki’s entire body tenses. Say no, Deku! Say no! Katsuki can still stand to lose more blood, she didn’t even specify how much, don’t let her—

“F-f—I, um,” Deku stumbles over his words, looking stricken as Katsuki—Toga—humps against him. “I d-don’t want you to hurt him,” he says. Katsuki can see it tearing him apart; had she just asked to break his bones, Deku would have agreed in a heartbeat. But getting fucked by Toga as Katsuki? Of course even Deku, self-sacrificial idiot that he is, would hesitate if the other side of the offer wasn’t that bad. “But, could you, um. Turn back into yourself? I’d r-rather do it with you, T—Himiko-chan,” Deku mumbles.

Katsuki’s stomach tightens and his hands burn.

What the fuck??

Why would he—Why would Deku choose—

“Oooh, Izuku-kun, you do like me!” Toga squeals, in Katsuki’s voice, and it sends a horrible shiver down to the base of his spine. “But maybe in a few rounds, okay? I already promised Kacchan I’d fuck you as him.”

Katsuki’s stomach drops out entirely.

“Don’t listen to her!” he roars, bucking against the metal that cuts into his skin. “That’s not—It’s not what that sounds like!!”

“I could have given you a blood transfusion,” Toga explains, her tone patient as she picks a scalpel up from the nearby tray. She makes quick work of cutting away Deku’s shorts and boxers as she says, “But he chose this for you, and now I get to fuck you with his cock. Isn’t that fun?”

Though he tries not to, Katsuki can’t help but flick his gaze down to Deku’s exposed privates. It’s not that it’s something he’s never seen before, having shared locker rooms and bathing areas together their whole lives. But never in this context.

It still doesn’t feel real, what’s about to happen.

“Wait,” Deku protests, his face a picture of horror as he struggles ineffectively in his restraints. “Please, no, not… not with him, please!”

Something ugly flares in Katsuki’s chest, like he’s just been offended. Why?! Why would he want Deku to want it to be him? This is not equivalent to them actually having sex.

“Izuku-kun, you’re making me so excited, look!” Toga croons, pulling her hard cock out of Katsuki’s sweatpants. “Wow, look how big your Kacchan is! How big I am!”

Tears leak out the corners of his eyes as Deku squeezes them shut. “You’re not him, you’re not,” he says.

“Mmm, close enough, though, Deku,” Toga hums, in a damn near-perfect imitation of Katsuki’s voice, and Deku sobs.

Katsuki’s hands try to detonate on nothing.

“We’re lucky that lubricant is part of this kit,” Toga says as she swaps the scalpel for a tube that looks like toothpaste. “Because I would have had to waste blood otherwise, and I really don’t want to. Have to save it all for the next game.”

Deku grimaces as Toga shoves two lubed fingers roughly inside his asshole, quickly pumping in and out in a sloppy show of preparing him for Katsuki’s dick. Katsuki can admit he’s well-endowed, and for the first time in his life he wishes he wasn’t.

All too soon she removes her fingers and replaces them with the tip of her cock, gripping Deku’s right hip with her free hand. “Ready, Izuku-kun?”

“No,” Deku whimpers, shaking his head. “Please don’t do this. Please. I’ll do anything else, just don’t do this, pl— augh!” he cries out, throwing his head back as she thrusts forward, impaling him on her cock in one brutal motion.

“So tight, Izuku-kun,” Toga crows, dragging back out only to shove back in. “So cute! So tight! I love you, Izuku-kun! Don’t you love me too, now that I look just like your precious Kacchan?”

“Stop!” Katsuki howls, thrashing in his chair. “Leave him alone!!” His heart feels cracked and his stomach is a hollow pit. This isn’t happening. It can’t be happening.

“Look in the mirror, Izuku-kun!” Toga grabs Deku’s tear-stained cheeks and turns him toward the pane, to face Katsuki directly. “Look into the mirror and show Kacchan what you look like when he fucks you.”

Deku’s eyes widen in horror.

Katsuki shakes his head as if it matters.

The green of Deku’s eyes vanish as he closes himself off, groaning out an anguished noise. He stays like that throughout the brutal fucking he gets, with a pained—almost defiant—look on his face. 

“Doesn’t it feel good?” Toga starts stroking his dick in time with her thrusts, and although he clearly isn’t enjoying himself, it grows hard under her ministrations.

He shakes his head as a bright flush blooms on his cheeks. She doesn’t stop.

This continues for what feels like ages. The chair squeaks, Katsuki’s grunts, and the little noises that Deku tries to suppress as he’s rocked into are repeatedly seared into Katsuki’s brain. He pointedly ignores the tightness in his own groin, refusing to acknowledge that any of this could be arousing. What the fuck is wrong with him?

Eventually, Toga pants, “I’m so close, let’s come together, Izuku-kun!”

Groaning, her pistoning hips stutter to a stop, staying seated inside of Deku as she rapidly jacks off his dick with Katsuki’s hand.

“I’m sorry, Kacchan,” Deku wails, with a voice that’s cracked and miserable.

Salt finds its way into the corner of Katsuki’s mouth. He tries not to look at the wet splatter on Deku’s shirt. Why would the nerd apologize to Katsuki? Katsuki is the one that condemned him to get raped.

No, I’m sorry, Izuku.  

Toga pulls out, a sticky trail following her softening cock. “That was amazing,” she sighs, leaning down to kiss Deku. He twists away but she chases his lips, continuing to stroke him as she invades his mouth with Katsuki’s tongue.

It’s a small mercy but it doesn’t last long. She stands upright and rotates the chair back to its original position, so that when she steps away, Katsuki has a perfect view of the cum leaking out of Deku’s abused hole.

“I’m gonna go ask Kacchan what he wants to see next, okay?” Toga says with an overly affectionate ruffle of Deku’s curls before she skips out of the room. Another motion that looks absolutely absurd with Katsuki’s body.

Though they glisten with tears under the harsh light above him, Deku keeps his eyes lowered. His expression is a crumpled picture of anguish, and Katsuki can tell he’s fighting to keep it together. 

Deku tries to close his knees but the chair keeps them spread apart.

“Don’t look,” he whispers.

Katsuki turns away.

The door to his cell opens and Toga strides in, wearing her own face and looking pleased as a cat that just ate the canary as she pulls her clothes back on.

“You demon,” Katsuki hisses. “The fuck did you do that for?”

“Why, Katsuki-kun, you told me to,” Toga says, feigning ignorance. “Don’t be ungrateful, when I gave you such a gift. I hope you liked the show.”

Resisting the urge to look at Deku, Katsuki keeps his glare fixed on the girl in front of him. “What the hell is wrong with you?”

“Many things!” Toga exclaims, full of glee. 

“Tch,” Katsuki spits. He hasn’t even begun to process the fact he just watched his own body rape his oldest friend. There isn’t time. They’re both still in danger.

“So what game is it now?” 

“Well! I really want to take your blood, but I promised Izuku-kun I wouldn’t take more than I need. So, how much do I need?” 

Katsuki narrows his eyes at her. “For what?”

She grins. “To fill Izuku-kun up with!”

He can’t help a quick glance through the glass. Deku is still there, still on display with his eyes closed. 

How are they going to get out of this?

“Converted blood?” Katsuki ventures. He got tricked last time, but he’ll be damned if he accidentally makes it worse by assuming Toga isn’t going to change shit on the fly.

“Of course! I take your blood, make it type O, and put it in Izuku-kun. Simple. How much do I need?”

Katsuki shifts in his seat, feeling sweat roll down his back. This is a riddle of some kind and he has to be smart about it. If he says none, sure he doesn’t get his blood taken, but what’s the catch?

Would she just fill Deku with something else?

Fuck. She’d probably fuck him again, to fill him with cum.

Or—worse—inject him with some foreign substance that would kill him.

Okay, so Katsuki needs to guess the exact amount of blood he has left to give, right? Assuming he can only spare a liter, and he’s given four vials, that leaves him with… how much? How much was each vial, like ten milliliters? Which would mean… he still has nine hundred and sixty left to give? Fuck, that seems wrong… that’s so much!? What if the vials were bigger than that?

But… a liter and a half is actually the maximum. And she definitely didn’t take a half liter yet, so taking a full liter should still be safe.

“A liter,” Katsuki says.

Toga smiles, baring her fangs. “Oh, Katsuki-kun, you’ll give me all of that?”

Katsuki swallows. He really doesn’t want to; he’ll be left with less than half a liter buffer between being lightheaded and needing a hospital. And what comes after that?

But another stolen peek at Deku has Katsuki nodding yes. He isn’t going to let that happen again.

“Okay, this is going to take longer than the samples, let me get a bag,” Toga says as if she’s explaining something mundane, like why dinner is going to be late.

She leaves Katsuki alone again.

Alone with Deku.

The audio feed is still coming through, piping Deku’s occasional gasps and whimpers right into Katsuki’s skull. Katsuki wishes it could go the other way so he could fucking say something.  

But what would he even say? I’m sorry? I didn’t mean to, I would never have picked that option if I had just been smarter about it and asked a few more questions?

“Kacchan.”

Katsuki looks up automatically.

“If you can hear me… I don’t believe her. So d-don’t… don’t worry about that.”

Christ. Of course Deku is concerned about how Katsuki is feeling, instead of thinking about himself.

“And… I didn’t want it to be y-you b-because… because—”

“Ready for your donation, Katsuki-kun!”

Whatever Deku says is cut off by Toga’s screeching as she prances back into Katsuki’s cell, an empty plastic blood bag held aloft.

Katsuki supposes it’s for the best. He doesn’t really deserve to know, anyway.

It doesn’t take long to attach the bag to his line, and Katsuki watches with a detached kind of horror as each beat of his heart fills the bag up more and more. He knows he needs this blood and is going to start to feel woozy pretty fucking fast, with a liter being about twice as much as a standard blood donation—another factoid that Toga gleefully shares with him. But it’s worth it to prevent Deku from getting fucked or fucked up. It should actually help, since Toga said Deku had already lost so much—

Though she didn’t actually… specify…

“How much blood has Deku lost?” Katsuki asks.

“Hm? Oh, not much. Just the two samples.”

Katsuki jerks against the chair. “What?”

“Yeah. I love Izuku-kun and I love blood, so what if he had even more blood? It’s not quite the same since it’s yours, but close enough.”

Red continues to pour into the bag, aided by the rapidly rising rate of Katsuki’s heart.

Tears prick at his eyes. Had he fucked up again? 

“Don’t do that,” he says, his voice hoarse. “He doesn’t need a blood transfusion.”

“Hm, maybe not yet, but this way I can take twice as much from him all at once! Isn’t that lovely? Oh, just look at him. Look how cute he is.” She turns to the window with a dreamy sigh, resting her cheek in one hand like a lovesick teenager. “This is gonna take like another fifteen minutes, so I’m gonna go play with him.”

“Wait!”

Katsuki grinds his teeth together, feeling the blood pulsing in his ears as it races to exit his body. He doesn’t want to do this, of fucking course, but he can’t… he can’t just sit here and let her do it to Deku again. “Wouldn’t you rather, uh. Play with me instead?” The words are awkward and stiff on his tongue, and he can’t do much in terms of suggestive body language. But the way Toga’s face lights up shows that she gets his meaning.

“Ohh, Kacchan,” she breathes, running a hand along his thigh. He tries not to flinch. “That is a very, very interesting counter-offer…” Chewing on her lip, Toga looks back at Deku with puppy-dog eyes. “But… Izuku-kun…”

“I’m way better than that nerd,” Katsuki insists. God, what the fuck is he doing?! This is the worst competition for him to win, but if he loses then Deku is going to suffer again. He’s already going to—Katsuki is pretty sure getting pumped with extra blood isn’t something the human body is equipped for.

Toga’s nose scrunches up. “Mmn, maybe for some people. But you’re just not my type, Katsuki-kun. I like cute little things that I can crush.”

“Wh—I’m cute! You fucker, I’m cute!” Katsuki shouts, desperate, as Toga sashays out the door.

Are you fucking kidding?? 

No, no—

“Izuku-kun, I’m back! Did you miss me?”

Deku’s eyes snap open and his entire body tenses. “Where’s Kacchan?” he asks, his gaze flicking to the mirror. His demeanor has shifted: back into fight mode already. Incredible.

“Right where I left him!” Toga chirps, pointing right through the pane at Katsuki. “He really loved watching me fuck you, and now he’s giving you a special gift! But it’s going to take a while, okay? So this is like… a bonus round.”

“What gift?” Deku asks, trying to shrink back against the chair as Toga climbs up on top of him, her knees digging into the minimal padding on either side of his waist. “What are you doing to him?”

“Gosh, you really care about him, huh? How about you care about me instead, like you said you wanted before?” She reaches down between her legs to grab at Deku’s dick and balls with both hands, pawing at them, forcing his cock to thicken and rise. At this angle, the view is mostly just Toga’s back—but leaning forward like she is, Katsuki can see that she isn’t wearing anything under her skirt.

Fuck!

He looks at the ceiling. He doesn’t want to watch this, either. The last time, he told himself he was watching for strategic purposes, but what did it gain him? Anything? No, he’s just a sick pervert, watching his oldest and closest friend getting raped.

“Ah!”

Katsuki looks. Fuck him, but he looks. He can’t see Deku’s face this time, which is both a blessing and a curse, because all he can look at is his dick disappearing into Toga’s cunt. 

“Is this better? Izuku-kun? Do I feel good?”

A whimper. Deku’s feet flex in their restraints.

“I wish I could… do both at the same time, ah,” Toga hums, lifting up on her knees just to slap back down until her ass is flush with Deku’s hips. One hand reaches back to brush fingers against Deku’s balls, his hole. “Maybe that can be, mm, next round? Get your Kacchan to take you from behind, while you fuck me? Would you like that better, if it’s actually him?”

“No!” Deku sobs, his brief resurgence of bravery already cracking. “Please, no, leave him out of th-this, augh—!”

Katuski sniffs, the air in his lungs feeling cold and tight. His entire body feels like a live wire, caught somewhere between appropriate grounded states. What did either of them do to deserve this torture? They’ve faced off against Toga a handful of times before, and she’d always had an acute fixation on Deku, but… this is so extreme. It’s so fucked up.

And Katsuki can’t even do anything to stop it.

He tried. He did. He did. Right?

Not hard enough.

Look. Look. Don’t look away, this is what you condemned him to.

“I’m sorry,” Katsuki whispers, his voice choked by the tears streaming down his face. This isn’t fair. He didn’t want this. He didn’t do this. It’s not his fault— it’s all his fault.

He feels genuinely sick, and after a beat remembers the bag of blood that’s been slowly filling up off to his left. Toga hasn’t given him any food to help with his depleted blood sugar—and depleted blood—so it’s no surprise it’s starting to affect him this much. On top of watching a repeat of Deku getting raped right in front of him.

Katsuki’s jaw trembles. Keep it together, keep it together. You’re not the one being hurt. You need to be strong.

You’re a hero.

Do something!

Katsuki renews his struggles, pulling on all of his limbs and bucking in the chair. He snaps his teeth at the line of red plastic tubing that steadily drains his life away, flecks of spittle lighting up briefly under the bulb before vanishing.

It’s no use. He can’t reach it.

Katsuki throws back his head and howls.

“Ah, ah, yes, Izuku-kun, give it to me!” Toga moans. “If you come inside, I can have your babies!”

“Fucking hell,” Katsuki swears, concurrently with another wailed protest from Deku. Just when it seemed like it couldn’t get worse, of course it did.

“No!” Deku cries. “D-don’t! Please! Anything else!”

“Hehe, anything?” Toga giggles, still riding Deku’s dick with practiced ease. “You have to let Kacchan and I fuck you at the same time, however I like it. Deal?”

“The fuck?!” Katsuki spits, still struggling futilely, his skin blistering where it touches metal. “I didn’t agree to that!”

Deku whimpers. He doesn’t respond immediately, and Katsuki hates how his own dick hardens in his pants as he waits, the combination of watching Toga ride Deku with the prospect of Katsuki fucking him on the table—fuck! What the fuck is wrong with him!? He doesn’t want that! You sick fuck!

“If—If you p-promise not to have either of us c-c—ejaculate inside you,” Deku says miserably, and Katsuki can’t blame him for having chosen the lesser of two evils. As much as he must not want to involve Katsuki in this situation, creating a whole new living being is definitely worse.  

They’re both in this together. Katsuki has skated by unscathed thus far, it’s only right he suffers too.

“Ohhh, Izuku-kun,” Toga cries out, her body vibrating as she comes on Deku’s dick. She sits down, rubbing at herself with her head thrown back so far that Katsuki can see the disgusting expression on her face.

“Get off, please,” Deku says, and Toga does—she practically vaults off of him, jumping to the floor and going back down on Deku in one smooth motion. “Hnng!”

Katsuki watches as Toga’s pigtails bob up and down, trying not to think of the sharp fangs surrounding Deku’s cock as she coaxes it to orgasm against his will. He can see Deku’s face now, can see the tear tracks cut down along reddened cheeks. 

He feels lightheaded.

“No, no, no, ah—!”

Deku’s hips buck up, and Toga slurps it all down.

“Yum, delicious,” she says, hopping up to her feet. “I think Katsuki-kun is probably ready for us now. I’m so excited! This is going to be even better than I had planned.”

When the door closes behind her, Deku immediately begins struggling; he yanks at the shackles around his wrists and ankles, fighting against them until it looks like his joints are going to pop. Eventually he collapses back into the chair with a frustrated sigh.

“Kacchan, I don’t know what to do,” he mutters.

Katsuki huffs. “That makes two of us.”

“Ding-dong, blood bag collection time!” Toga singsongs. “Ooh, you’re so full, Katsuki-kun!”

Wrinkling his nose, Katsuki ignores the comment. “What’s it going to take to get us out of here, hah?”

Toga stomps her foot. “No! That’s no fun. I want to have fun.” She disconnects the bag and nuzzles her cheek against it. Gross. “This will be fun. We can fill Izuku-kun up together.”

Katsuki feels cold. “You’re gonna… give him the transfusion while we… do that shit?”

“If you can still get it up without this,” she says with a smirk, cuddling the blood bag.

He doesn’t respond to that.

“This is gonna take a bit to set up, so just… keep sitting there, okay? Not like you can do anything else!”

It’s true. All Katsuki can do is watch as Toga hangs his blood bag next to Deku, connecting it to his arm and presumably reversing the direction.

“What is that?” Deku asks, his voice wary. Right. He has no idea about this part.

“It’s Katsuki-kun’s blood,” Toga says reverently. “But don’t worry, I made sure it’s just your type.”

Deku jerks. “That’s—That’s a lot of blood,” he says, panic spiking through the words. “Is Kacchan okay? Can I see him?”

“Excited for our threesome, huh?”

Green eyes flick to the mirror, then back down to Deku’s bare lap. He’s still half naked and spread open.

“Don’t worry, Izuku-kun, I just need to… hm. You know what? This is going to be a little tricky, now that I look at it.” She tilts her head back and forth, examining the chair, bending down to peer too closely at Deku’s genitals.

He squirms.

“That’s okay, I have another room we can use.”

Katsuki inhales sharply. What? She’s going to move him? Katsuki won’t be able to see… he’ll have no idea what fucked up shit she’s doing. Watching is awful, but not knowing is worse.

“Now, I’m going to transfer you, but if you try to escape, it’s going to go very badly for your Kacchan. Even if you get away, you won’t be able to get into his room and Katsuki-kun will bleed out, okay? So be a good boy and let me move you.”

“What?!” Deku yelps. “Is he—Is he still losing blood? Right now!?”

Katsuki looks down at the tubing in his arm, half expecting it to be pouring out onto the floor. It’s not. Of course it’s not. She just says whatever the fuck she wants, and they both keep believing her.

“Yes, so we’d better be quick about this, hm?”

When Katsuki lifts his head, Toga already has Deku unhooked from the chair, pulling him out of it onto unsteady legs. He looks so vulnerable, with his nude bottom half and an uncertain expression on his face. He keeps glancing at the mirror, at Katsuki.

Run. Fight. I’ll be fine.

If only they really had some kind of psychic connection, fuck!

Deku’s hands are still encased in the same quirk-suppressing blocks of metal that keep Katsuki’s locked up, now attached to each other instead of the chair. How convenient that they’re so portable! Toga leads him out of the room by his bound hands, and Deku goes along willingingly, the bag of blood rolling after him.

Katsuki sags in his chair.

He feels sick. Waves of nausea begin to roll through him, like his equilibrium has been messed with. What’s going to happen to them? Is he going to die from blood loss after all? And Deku, was he just similarly taken to his death?

They could only be so lucky. Katsuki doesn’t know how long it takes for Toga to come for him, but it’s both an agonizing wait and far too soon. In her hands is some kind of metal contraption that Katsuki wants nothing to do with.

“Okay, Katsuki-kun, we’re ready for you! I’m gonna put this muzzle on you first though, okay? I don’t trust you as much as I trust Izuku-kun.”

Katsuki bares his teeth at her. She giggles.

“Yeah, exactly. Open wide!”

She presses the horrifying mask over Katsuki’s face, and although he tries to resist, it doesn’t take much to force the metal bar between his teeth, pinching the skin of his lips on the way in. A few seconds more and the entire thing is secured tightly behind his skull and around his neck, with a thick chain dangling from it like a leash.

Katsuki shouts, growling around the gag, and—

Nothing. He hears nothing at all.

“Custom made for noisy ones like you,” Toga explains, holding the mask between her hands and kissing it over Katsuki’s nose. “I don’t want to hear you at all.”

Shaking his head doesn’t dislodge the awful thing, but that doesn’t stop Katsuki from trying. What the fuck!?

“And a final touch. I was joking about you not getting it up,” she says, pulling out a hypodermic needle and immediately driving it into Katsuki’s arm. It pinches, but that’s the least of his worries. What the fuck is she— “This will help you stay hard. I don’t want to disappoint Izuku-kun if you get cold feet, hm?”

What the fuck. What the fuck?!

“Now, just like I told Izuku-kun, I’m going to move you. You’re going to have a little more freedom than him, but… I wouldn’t try anything, if I were you. I’m not the only one down here, y’know? I’m just the only thing stopping everyone else from fucking him. Well, and you, too, though I don’t know who would pick you over him. The noumu, maybe,” she says, tilting her head. “But even then. Izuku-kun is right there.”

What’s left of Katsuki’s blood is boiling, his heart going haywire in his chest. She’s lying. She’s lying. She’s been doing this the whole time! You just saw her lie to Deku to keep him compliant. She’s doing it again. She is! There’s no way… no way getting fucked by noumu is a real threat.

Right?

Toga unlocks the chair’s restraints.

This is his chance. Fight.

She secures his hands together behind his back.

Run.

Katsuki lets her lead him out of the room.

They walk down a long hallway, past the room that Deku was in and many other rooms like it. Katsuki floats along feeling sick and hot. Eventually they come to an open door; Toga pulls him inside by the chain, and he freezes a few steps from the entrance.

Deku is there in the center of the room, on a raised platform. He’s on his elbows and knees and chained down by them. His clothes are gone; he’s entirely naked except for the blindfold covering his eyes.

The bag of blood stands next to him, dripping into his veins.

This is a nightmare. There’s just no way this can possibly be real.

“Yay, Kacchan is here!” Toga says cheerfully, tugging at Katsuki’s lead to bring him closer. “Now we can both fuck you together!”

“Kacchan?”

Deku’s voice is small. Scared.

Katsuki rattles his chains in response.

“Ooh, Kacchan can’t say anything, I’m afraid.” The words are laced with fake concern. “But I promise he’s here!” She yanks Katsuki over to stand directly behind Deku until their hips are level, and attaches the chain to a bolt in the platform. 

“He’s not, is he?”

Toga’s hands still, paused at the hem of Katsuki’s sweats.

“Was he ever here? Did you just get his blood from somewhere?”

A slow grin begins to spread across Toga’s face.

“Or did you kill him?”

“So many choices,” Toga hums. She pulls out Katsuki’s cock and begins to languidly stroke it. “I guess you can believe whichever you want, Izuku-kun. Whichever makes you happiest!”

Katsuki thrashes, trying to protest and resist, but a sharp squeeze of his balls and the cold press of metal against his stomach brings him to heel. It’s the scalpel or her usual knife; Katsuki can’t see it around the mask on his face, but it doesn’t really matter which one it is. Either option can spill his intestines on the floor in seconds.

“Maybe it’s your Kacchan I have here,” Toga says, “Or maybe I’ve got a pet noumu instead. Dumb. Mute. Big! Would you like that, Izuku-kun? A nice fat noumu cock to rearrange your guts?”

Deku is shivering, shaking. But he says nothing.

Though he begs his body to refuse, whatever drugs are swimming in his depleted blood have Katsuki rapidly growing harder than he’s ever been in his life. He wants to touch himself, wants to jack off and make it go away. Wants to fuck something.

“Mm, right this way, Kacchan,” Toga purrs, guiding Katsuki’s cock to bump against the rim of Deku’s hole. No, no, not this, not like this—

She grabs his hips and shoves him forward.

No one can hear Katsuki groaning as his cock is buried in Deku’s tight heat, with his voice locked away behind the contraption on his face. So the only sound is Deku’s cry of shock that lances right through Katsuki’s heart. Tears well up in his eyes, hot and blurry. 

“Come on, you stupid animal, fuck him. Don’t make me do it for you, or I’ll cut off your useless dick.”

“Just listen to her, Kacchan,” Deku grinds out through his teeth. 

Katsuki’s heart feels heavy and off-beat. His head feels fuzzy and his cock feels amazing. He slides it back out and snaps his hips forward, eliciting another delicious noise from the body under him.

“Oh! Is that the option you’re going with? Good choice, though I would have picked noumu. Mm, I really love watching you get fucked… I’ll have to get some more friends to join us later.” Toga prowls around like a cat, pawing at them both as she pleases. Tweaking Deku’s cock, his nipples. Katsuki’s nipples, his ass. The sick sounds of skin slapping against flesh fills the space. Katsuki can’t block it out.

Eventually she slips under Deku’s body, hooking her legs around his back and one of Katsuki’s hips. Deku whimpers, and Katsuki can tell that she’s gotten him inside of her.

“Izuku-kun, did you miss me?” She squeals, peppering his neck with kisses. “Isn’t this what you wanted? Both of us, together?”

“No,” Deku sobs, rocking back and forth as Katsuki pounds into him. 

Katsuki can’t think about what is happening. He can’t. It’s not happening. This is just some messed up sex dream that he’ll feel weird about for a half hour and then forget about by lunch.

“Hmph!”

Toga rolls back out, popping up onto the balls of her feet. She shimmies out of her clothing and kicks it across the floor, out of the way of the gray sludge that envelops her body as she transforms back into… Deku.

“Fine. If you don’t like when I fuck you as me, or as Kacchan, maybe you’ll like getting fucked by yourself.”

Katsuki just stares, wide-eyed and dizzy, as Toga-as-Deku shoves her cock into Deku’s mouth.

“You keep saying no when you should be saying yes, yes,” Toga moans, in Deku’s voice, her scarred fingers in his hair. “Fuck me, Kacchan, fuck me.”

The orgasm hits him before Katsuki realizes it was building, snapping like a string through his abdomen as he buries his shaft as deep as he can force it, unloading into Deku’s ass like a water hose. He should pull out but he can’t, too dazed and drunk and horny to do anything but just let it happen. 

Deku moans around the intrusion in his mouth, gurgling as he’s facefucked by his own dick.

Katsuki slips out, falling to his knees with a hard thump. His head is full of static. He feels like he’s dying.

He looks up to see Deku’s body completely limp. Toga is holding him up by the hair as she humps his face, but he’d be completely collapsed if she wasn’t. Did he pass out from getting fucked? Did she suffocate him?!

Warning bells go off in the back of Katsuki’s mind, something he’s forgotten about—

Deku is convulsing.

His skin is pale and covered in sweat, his ankles are swollen—

Katsuki lurches forward with all the slack his chain will allow, landing on the line of blood and tearing it out of Deku’s arm. It pulls the stand to the floor, and the bag explodes in a dramatic shower of red splattered across the floor.

“What are you doing!?” Toga shrieks, melting back to her own body. “Bad dog! Bad!” She grabs Katsuki by the facemask, shaking him. It feels like his brain is rattling in his skull; he’d vomit, but his mouth is occupied—until the clasp gives way, and the whole thing comes off in her hands, dropping Katsuki to the floor in a pool of his own blood.

“You’re gonna kill him,” he rasps. His head is pounding and he can hardly think. It doesn’t matter. It doesn’t matter what happens to him. Deku is dying, and Katsuki can’t save him. He answered every riddle wrong. It’s all his fault. The only person that can save Deku is the one that put them here in the first place. “He needs a fucking hospital. If he dies, you can’t play with him anymore.”

Toga opens her mouth like she wants to protest, but her eyes land on Deku and it turns into a pout. “But more blood made him more beautiful.”

“Then enjoy it, because it’s a one-time use. He dies, you need to find a new toy.”

Screwing up her face for a moment, Toga finally relents with a sigh. “Fiiiiine. You two were boring me anyway, being completely at my mercy. I miss the chase.” She scoops up her clothes and saunters to the door, hitting the button on an intercom on the way out. “I’m done here, I need cleanup.”

“Hospital!” Katsuki shouts, desperation cracking the edges of his voice. He probably needs one too, but fuck it, he’ll stay here and bleed out if that’s what it comes to.

“Yeah, yeah, drop them at a hospital, sheesh.” She adjusts her bundle of clothing in her arms, looking back at Katsuki over her shoulder, saying, “You know, I was pretty jealous of you, Katsuki-kun, but I have to admit. I like seeing you covered in blood.”

She grins, and Katsuki shivers.

“See you later, lovers!”

Katsuki slumps against the pedestal when she’s finally gone, all of the tension and adrenaline draining out of his body. His feet and fingers feel cold.

His cock is still half hard and outside of his pants.

“Kacchan…?”

“I’m here,” Katsuki says quickly, trying to twist around to get closer, though it’s difficult with his arms bound behind him. He knows he shouldn’t rest, should get up and try to escape… can he actually trust that Toga hasn’t just left them to die?

But he’s so dizzy. He can barely sit up.

“Is it r-really… you?”

“Yeah,” Katsuki breathes. “Sorry. I… I’m so fucking sorry, Izuku. She did all that shit to you and… so did I.”

Deku nudges the blindfold up with his shoulder, peeking out at Katsuki with red-rimmed eyes.

“Kacchan,” he chokes out. “I’m s-so glad you’re alive.”

A wry smile tugs at the corner of Katsuki’s mouth. “Kind of hard to kill. Missing a lot of blood though.”

“Mm. Don’t feel good, Kacchan,” Deku whispers, a shudder running through his body. “Dizzy. Chest feels weird.”

Katsuki’s does too, as worry and anxiety take up residence alongside the blood loss and nebulous drugs. Is help actually coming?

“Help is coming,” Katsuki says.

“Yeah?”

He’s so tired. Katsuki rests his head against Deku’s arm, letting his eyes slip closed.

“Yeah.”

Deku sighs, and his body shifts its weight into Katsuki a little bit. They’re so close, Katsuki can hear the hitch in his voice when he whispers, “S-someone’s gonna see me like this.”

Katsuki tries to swallow past the lump in his throat. He wishes he could deny it or could do anything about it. But with his hands locked behind his back and chained to the dais, he’s ill-equipped to change their predicament. “If it makes you feel any better, my dick’s still hanging out, too.”

“Are you… okay?”

The muscles of Katsuki’s jaw clench. He’s fine. He’s lost some blood and has some kind of boner pill in what’s left, but he’s alive. Frankly, it barely registers on the scale of worst injuries. He’s fine.

“Yeah.”

When Deku says “I’m glad,” like of course he would, something in Katsuki’s stomach sours. When it’s followed by a mumbled “Glad you’re here,” something snaps.

“Why?” Katsuki nearly spits. He pulls his head up, suddenly appalled by the close contact. “After I just—I just fucking… I fucked you. I just fucked you.”

“I know,” Deku says quietly, his voice choked and almost unintelligible. “But she made you. Not your fault.”

“Bullshit,” Katsuki seethes. He tries to blink the tears out of his eyes but everything blurs and stings. It’s not fair to do this right now, but he can’t stop the words from spilling out, saying, “You specifically didn’t want it to be me. And then she fucked you as me. And then I fucked you.”

“Kacchan, p-please stop saying that!” 

Katsuki bites his lip hard enough to taste blood. It’s incredibly wasteful when he has precious little left to lose.

“L-look, I’m still… this is a lot for m-me right now, okay? I can’t…” Deku shifts, his posture bending as he tries to find any kind of relief from the awkward position he’s been locked into. “Yes, I didn’t want Toga to b-be you. But not because I don’t like you, or wouldn’t—wouldn’t want—I just—it hurts more, okay? I can’t explain it. I just care about you too much.”

Oh.

“And when it was actually you, I thought you were dead. So I don’t really care about the rest. I’m just—” Deku cuts off mid-sentence, slumping back onto his heels. “...We have to get out of here, Kacchan. This can wait.”

Katsuki nods, shaking his head until his vision clears. Deku’s right. They can’t just sit here and wait to die.

With a grunt, Katsuki rolls onto his back. It takes some wriggling and strained joints, but he manages to pull his arms under his ass and up his legs, slipping his feet out and getting his bound hands situated in front of him. Okay. Step one.

Step two is a little harder. Katsuki is light headed and woozy from blood loss, and standing upright is a challenge. But not one he’s going to shy away from. With an internal Plus Ultra, he shifts onto his knees and then lurches up to standing.

He sways dangerously.

But remains on his feet.

Okay. Okay. Step three.

“I’m gonna try to break this against the shit you’re on, brace yourself,” Katsuki says as warning before smashing the shackle into the corner of the platform. The impact reverberates through his bones and fucking hurts both of his hands, but it puts a dent in the metal.

“Try to aim for the latch, it might release,” Deku suggests. Katsuki inspects the contraption for whatever that means and finds the lock situated in the middle. It’s a much harder spot to get any leverage on, but he can probably swing it between his legs like an old lady chucking a bowling ball.

Crack.

His aim is true, and the shackle pops open, freeing Katsuki’s hands for the first time in what feels like years. He feels his quirk come rushing back to him in a dizzying rush, which brings him crashing down to his knees.

“Kacchan?!?”

“I’m fine,” Katsuki rasps, leaning against the edge of the platform. He tucks his dick back into his pants and makes quick work of releasing Deku’s knees; thankfully they aren’t locked with much more than a straightforward latch. His forearms are another matter, encased in the same quirk-canceling manacles as Katsuki’s had been. But after some poking, jiggling, and slamming Katsuki’s discarded set into them, they finally spring open.

It’s automatic, what happens next; Katsuki pulls Deku off of the platform and into his arms, onto his lap on the floor. Deku is small but Kasuki wishes the difference were even greater, so he could more fully cover that vulnerable, exposed body with his own. A second later, his brain catches up to him, saying, Hey asshole, maybe he doesn’t want to be held by his fucking rapist??

But Deku’s arms wrap around Katsuki in turn, clinging to him. He’s shaking and shivering but he’s warm and alive. Katsuki puts a hand in his hair, anger flaring back up when his fingers touch fabric. He pulls the blindfold entirely off and tosses it across the room.

Fuck this place.

“Why hasn’t anyone shown up?” Deku whispers.

Good question. If Toga only stopped torturing them because Deku needed medical attention, where is it? 

Or was that not it at all, and she really was just bored with them?

And left them to die?

“Dunno,” Katsuki says, shifting Deku off of him. “But she’s been lying through her pointy teeth since we first woke up here, we can’t trust anything she says. Gotta get out of this on our own.”

“Right, okay.” Deku pushes himself up onto wobbly feet, and Katsuki follows.

They’re both a mess, despite having had relatively little done to them: sick, dizzy, and weak, smeared with body fluids with just one pair of clothes between them. Katsuki strips off his sweatpants and hands them over. They’re soaked in blood but it’s better than walking around completely naked, and Katsuki can make do in his underwear.

“Think you can fight?” Katsuki asks.

He knows Deku will anyway if they have to, even if he can’t. Who else is down here? Is there really a hive of villains they’ll have to fight through? Noumu? At least Deku’s been looking a little less like death since the transfusion got disconnected, so maybe he’s not in as much danger anymore.

Deku grimaces, but nods, his face pinched with a combination of pain and determination.

Yeah. He’ll fight.

And the average human body has about five liters of blood, which means Katsuki still has four left.

That’s plenty.
