Behind Enemy Lines

Chapter Text

Izuku’s knees ached against the cold, hard floor. He had been forced to kneel in this same position for close to an hour with nothing to look at but the onyx colored throne before him. Part of him hoped that someone, anyone would return. The other part of him remembered that he was a captured prince on foreign soil and hoped that no one would ever return for him, allowing him to die from starvation so he wouldn’t have to live another second with the knowledge of his nation being defeated.

Izuku shifted around purposefully, desperate to find a way to dislodge the cursed necklace off his throat, but it was no use. The jewelry just wouldn’t budge. The magicked stone sat in the center of the fine silver choker, inlaid with emeralds, rubies and fire opals on either side. Under normal circumstances, he would have found the piece of jewelry appealing, beautiful even. But at the moment he only felt repulsion towards the necklace. If it weren’t for the ropes twisted tightly around him, restraining his every movement, he would have torn the jewelry apart and restored his own magic in a matter of seconds.

Izuku looked up as he heard approaching footsteps and disembodied voices in the distance. He was barely able to distinguish snippets of their conversation, while still unable to see them. He tilted his head towards the direction of the sound, straining to hear more.

“The captive is already in there? Has he been secured with binding ropes and the choker?”

“Yes, your Majesty. They were just enchanted this morning and placed upon him in the afternoon.” the other voice responded.

“Good. Tell no one to disturb me for the rest of the night. I have business to attend to.”

“Yes, my king.”

Finally, one of the voices’ owners came into view. No introductions were necessary, Izuku recognized the person standing before him in an instant. Katsuki Bakugou his mind supplied helpfully. The man was tall and lean, easily a good few inches taller and a few years older than Izuku. But what really stood out to the trapped prince were the blood red eyes burning wildly with traces of dragon fire in them. The rumors about Bakugou’s stunning good looks had not been exaggerated, Izuku thought to himself bitterly. Such beauty wasted on someone so wicked.

The foreign king was victory personified, fighting and conquering across the entire continent without a single defeat. His brutality and efficiency were infamous amongst the various nations. The Yagi Kingdom had resisted as long and as valiantly as they could, but with the failing health of Izuku’s father they ultimately succumbed to the dark tidal wave of the Bakugou nation. Izuku had started today like he had every day of his life prior - as prince of a beautiful and prosperous nation - and by nightfall he had become a captive.

The blonde looked him over hungrily, eventually opting to examine the prince’s body with his own hands. The king drank in his appearance and his pupils dilated with obvious arousal. Izuku glared at the king and scooted away as best as he could with all of his limbs bound.

“Typical fucking Midoriya. Stubborn even in the face of total defeat. Your people have been a real pain in the ass for years now.” Izuku said nothing so the blonde continued. “Your father was a thorn in my side for most of his unnatural life. When I heard that he was deathly ill, on death's very own doorstep, it was the greatest day of my life. Until today, of course.” The ruby eyed king smirked.

Izuku stayed calm, despite the anger bubbling inside him violently. He knew that his enemy was merely trying to force a reaction from him, even though he had never met the infamous creature before today. He had learned a lot in his royal strategy classes about the other rulers that surrounded their kingdom and he knew that the draconian king was a unique brand of cruel, preferring to play with his food before eating it. He wouldn’t allow Bakugou the satisfaction of breaking his morale in any way.

“Not feeling very talkative, huh?” Katsuki mused aloud, almost as if he were reading the green haired man’s mind. “That’s okay, your father wasn’t particularly conversational either. Come to think of it, neither was your mother. Maybe it runs in your pathetic family?”

That captured Izuku’s attention immediately. His father’s passing has been imminent, even before Bakugou’s forces had invaded their lands. He had made peace with his father’s upcoming death a long time ago. He was able to say his farewells and everything, in fact. But his mother?

Last he knew, his mother had been sent away in secret so that she might survive the ordeal. She certainly didn’t have any sort of medical condition limiting her possibility for a long life like his father had. Izuku had held out hope that they would one day be reunited, in spite of the tragedy that fate had dealt them. His mind raced through every possibility of what this foreign king might have done to his parent, silently praying that the ash blonde was merely bluffing.

“What did you do to her, you bastard?!”

“Oho, so the young prince does speak. I was beginning to worry that my new prize was defective.”

“I’m no prize of yours!” Izuku shouted. “Now tell me what has happened to my mother!”

“No prize of mine, huh? You’re sitting in my fucking throne room in chains, completely at my mercy to whatever I may will and you don’t believe yourself to be my prize? What are you then?”

“A prisoner of war.” Izuku hissed back.

“Perhaps. But I’m not sure if that is all you will be. I’m still debating what to do with your ass.”

Izuku frowned at the barbaric king’s choice of words. It was entirely possible that the blonde was speaking in general about his uncertainty on what to do next with Izuku. But the dangerous glint in Bakugou’s eyes sent an unconscious shiver of fear down the freckled prince’s spine. The action did not pass by unnoticed and a maniacal grin stretched across the king’s face.

“My mother.” Izuku repeated. “What did you do to her?”

“You really want to know, dontcha? Very well, what do you offer in trade for this information then?”

“T-trade?” Izuku parroted back, confusion coloring his face.

“Yeah, dumbass, trade . I give you something you want and in return you give me something I want. Didn’t your kingdom pride itself upon being a beacon of fairness and light against a sea of dark, unworthy creatures like my people? Seems like this lesson was lost upon the one who would have inherited it all. Maybe I actually did your people a favor.”

“What do you want?” Izuku asked, ignoring the other’s blatant jab at his character.

“Would you beg me to know what happened to her, hmmm? A beautiful, proud prince such as yourself lowering himself to do something so degrading? I bet you would. I bet you would beg so goddamn prettily.”

“I-Is that what you want?” Izuku wondered in a small  voice.

“Yes, but that’s not all I want. Your mother is alive, but I won’t allow you to see her until you give me what I want first.”

“How do I know this isn’t some sort of trick and that she isn’t already dead?” Izuku asked suspiciously.

“I thought you might say something like that.” Bakugou’s Cheshire grin widened. “I asked her to tell me a secret, something only you would know about or else I’d run my knife through you. What do you think she told me?”

“I-I don’t know.”

“I think you do.” Bakugou insisted. “Who else alive knows the truth about your borrowed power besides you, huh?”

Conflicting emotions cascaded over him. Fury washed over him in waves as he saw the blonde’s smug expression, knowing that the secret about One for All was no longer confined to his family. But ultimately, relief won the battle for his heart. His mother was alive somewhere and Bakugou knew where that somewhere was. The blonde had even hinted that Izuku would be allowed to see her, but at a price. Just what was this price? What could Izuku possibly have to offer to the man who seemingly had everything he wanted?

“Fine, I believe you. What do you want from me?”

“I don’t want anything from you. I want you , all of you. Your body, your heart - all of it belongs to me.”

“But, but I don’t understand.”

Bakugou’s barked laughter echoed around the expansive throne room. “What don’t you fucking understand?”

“Why you want me like. Like that .” Izuku murmured anxiously. “You hate my kind.”

“No, no, no; I don’t hate your kind! I just want to see you all in your proper place. Beneath me. Especially the pretty ones.” Bakugou explained with a smirk. “Though I highly doubt I’ll find another as gorgeous as you so you might just be all I need until the day I leave this world.”

Izuku recoiled in horror at the king’s proposal. The young prince had never seriously entertained the idea of mating with another, despite the frequent offers of courtship he declined. But he always imagined that when he did finally reach that time in his life he would find someone kind and strong… and that he would actually have a choice in the matter. The option being presented to him now offered neither of those things. He already knew what he had to do though.

“I agree to your terms.” Izuku said with an air of finality, knowing full well he was signing away his life to this wretched man in exchange for keeping his mother alive.

“I knew I could count on that famous goddamn martyr complex.” Bakugou said triumphantly, his red eyes glowed faintly like burning coals. “Let’s get started, shall we?”

Izuku knew it wasn’t a real question but he found himself nodding affirmatively anyway. That seemed to please the blonde and he leaned down into Izuku’s space. Their faces were mere centimeters apart, sharing the same air between them.

Izuku gasped as the blonde pressed their lips together roughly. Bakugou quickly slid his tongue into the other’s mouth, asserting dominance and taking exactly what he wanted from the smaller male. Izuku cringed inside.

All of Izuku’s training, years of combat practice all amounted to nothing without his magic at his beck and call. His hands itched to unleash black whips from his fingertips and wrap them around his enemy until the light left those blood red eyes.

“You seem pretty observant. You figure out how your  restraints work yet?” Bakugou asked casually.

“At first I thought they were just designed to keep me from moving at all. But then I realized they only move when you’re focused on them. I think you’re the one controlling them.”

“Not bad for a spoiled prince. What do you think of the enchantment?”

“It seems like the perfect spell for a sadistic barbarian like you.” Izuku snarled.

“Mmmm, you have no idea. But you will. Soon.” Bakugou promised darkly, gripping unruly dark green curls in his hand tightly.

Bakugou snapped his fingers and the ropes loosened around Izuku then  slunk to the floor. It felt almost strange once the bindings fell off him. They had been wound around his body for so long.

The greenette nearly jumped a foot into the air as he felt a rough hand slip under his shirt. Goosebumps exploded over his skin as the fabric covering his torso was being forcibly removed.

“Wh-what’re you doing?” Izuku stammered out as the blonde’s wayward hands kept moving, deftly removing his breeches next.

The explosive king didn’t stop until Izuku was fully naked before him, not bothering to answer the freckled male’s question. The prince couldn’t look away as Bakugou began to undress next. His brain screamed at him to avert his eyes, but he found himself unable to look away. The hard earned muscles and unmarred skin in front of him were truly a masterpiece.

“See something you like?” Katsuki’s voice broke him out of his reverie. Izuku turned his head away defiantly, refusing to acknowledge anything. The blonde chuckled quietly at him.

The blonde carefully positioned Izuku onto all fours. The greenette tried to look over his shoulder so he could watch Bakugou’s every movement but the king merely pushed his head back down. Izuku hated the feeling of being blind and powerless.

Izuku’s eyes widened to the size of saucers when he felt the unmistakable pressure of a finger pressed between his cheeks, rubbing over his hole. Bakugou’s other hand remained stationed on Izuku’s hip. The greenette hissed in pain as the finger worked its way inside him. It was little consolation to his never before touched entrance that the finger had been evidently slicked up with oil before entry. Izuku could feel the excess liquid falling from the finger onto his skin. The green haired man bit his lip in an effort to keep any undignified noise from escaping.  

Bakugou pumped his finger in and out meticulously before adding another a few minutes later. The blonde scissored his fingers purposefully. Deeming the smaller male sufficiently prepped a short while later, he removed his fingers completely. Izuku still couldn’t see what Bakugou was doing but he heard the wet sounds of liquid on skin and realized that the older male must be slathering more oil onto himself. The blonde lined up his length to Izuku’s hole and the freckled male tried to squirm away. Katsuki’s grip on the other’s hips increased, preventing his escape.

The blonde pressed in ever so slowly, mesmerized by the sight of his cock disappearing inside that tight, warm entrance. Bakugou groaned unashamedly as he eventually bottomed out. Izuku’s breathing was labored and ragged like the air had just been punched from his lungs the king noticed. He began rubbing soothing circles into the greenette’s lower back.

“H-hurts! It’s too, too big!” Izuku said in a low voice.

“Ssshhhhh.” The blonde purred into the shell of Izuku’s ear. “It’s okay. You’re doing so well. Such a good boy taking my cock like this. You feel so fucking good around me.”

Izuku took a few calming breaths. The blonde surprisingly didn’t move an inch while he waited for his captive to adjust. When the prince’s breath steadied, Bakugou pulled his length out of Izuku until only just the tip remained. He moved his hips forward gradually until their bodies were flush together then repeated the process over and over until Izuku unconsciously started rocking his hips back to meet each thrust.

The pace escalated after that to a dizzying, frantic rhythm. Bakugou pumped his throbbing member in and out roughly, the sounds of skin slapping against skin filling their ears. Green curls bounced chaotically as the former prince was jolted forward forcefully.

Izuku thought the violent king would chase after his own pleasure with no regards to Izuku’s, which suited the greenette just fine. The freckled prisoner didn’t want any part of his body to enjoy the assault being launched against him. But then the ash blonde suddenly angled his hips in such a way that his cock brushed against the sensitive spot deep inside Izuku. The smaller male cried out loudly as pleasure began mixing with the pain, adding insult to injury.

“You like that, you pampered piece of shit? Hah?!” Bakugou growled. Izuku’s eyes rolled to the back of his skull, he was too stunned to form a coherent thought.

“Fucking answer me!” Bakugou commanded; this time aiming a harsh slap at the prince’s round backside.

“N-no! I don’t! I don’t like it!” Izuku managed to say.

“You sure about that?” Bakugou taunted him. “The way you’re clenching around my cock and this,” Bakugou wrapped a large, calloused hand around Izuku’s aching erection, “make me think otherwise.”

Izuku attempted to hide behind his arms, but the blonde grabbed a wrist and ignited his magic, burning Izuku’s skin in the process. The prince let his arms fall to the side, his body becoming slack for the king to use as he wished. If it weren’t for Bakugou’s quick reflexes springing into action to catch the smaller male in his arms, Izuku would have fell to the ground.

The intimate nature of the King’s embrace made nausea boil in the pits of Izuku’s stomach, threatening to spill out of his mouth. Knowing such behavior would only irritate the blonde further, the greenette dutifully swallowed down the acidic mixture. He felt his trachea burn as the bile descended down his throat. This whole experience was a jumbled mess of mixed gestures from Bakugou. The king was uncharacteristically considerate and kind one moment then degrading and selfish the next.  

Izuku shrieked as his orgasm was ripped from his body by the clever fingers working his length and the dick pounding his prostate. Warm liquid shot out from his cock, drenching his chest and the floor. The walls squeezing around Bakugou’s member suddenly tightened, clenching around him like a vice.

“Fuck!” Bakugou yelled a second later as his orgasm hit.

The blonde came inside Izuku, pumping the other full of his seed, and bit down on the smaller male’s shoulder until he drew blood. Bakugou slumped against Izuku’s pliant form, causing them both to sink to the floor. They laid there chest to back as they both struggled to come down from their postcoital high. Izuku glanced over at the man who had just taken his virginity against his will. The blonde looked positively radiant with a peaceful, content expression on his face. A dark shadow fell over Bakugou’s face though when he opened his eyes and ruby met emerald. He shoved Izuku’s face into the ground without warning and spoke directly in his ear for the thousandth time.

“This is your fucking life now, got it? You ever try to leave me and I’ll slit your mother’s throat same as I did your father’s, while you watch. Understand?”

Izuku could barely hold himself up but found a way to nod in agreement numbly, still trembling all over his abused body. His muscles ached in protest from the small action. It seemed like every fiber of his being had been viciously disassembled and then reassembled to Bakugou’s liking.

“Good boy.” Katsuki repeated the same praise from earlier, gently kissing the younger male’s sweaty forehead. “Oh, and one last thing - I think a new name is in order since Izuku Midoriya is the name of a prince, don’t you? Not the name of my new mate.”

Not waiting for an answer, the king laughed madly as he carefully stood up, straightening his pants to their original position. “I’ll be back soon to clean you up, Deku .”

Izuku fell forward onto the ground as soon as the blonde walked away and was no longer visible. He registered pain blooming across his wrecked body from the impact, but all he could feel was the lingering touches of Bakugou’s hands across his skin, his fingers claiming Izuku’s most private areas, the cum still dripping from his hole. The one time prince shuddered as sobs suddenly wracked his body and he cried openly onto the stone floor, surrendering to the hopeless feeling of despair in his chest. He woke up a few hours later in a soft, warm bed and for a brief, shining moment he imagined that maybe it had all just been some horrible nightmare, but then he felt a body stir next to his own. Strong, confident arms wrapped around his body and pulled him closer.

“Finally, you’re awake. Ready for round two, Deku?” A gravelly voice whispered in Izuku’s ear, lips brushing against his skin.

Izuku wasn’t ready. He would never be ready. But he had no choice - this was his life now after all.
