First story in a while! This is pretty lengthy, and I have a part two with more smut to it (yay!) coming right up. I hope you enjoy, since most of this is fine until the very end. Spoilers from episode 38 and on, I believe.

"Damn it, Akaba! I'm not playing this game with you!"

The young CEO quietly pushed his glasses up his nose as he sat and endured the shouting from the man before him, biting his tongue and waiting until the other was finished ranting and raving at him. Shun Kurosaki slammed his hands on the desk in rage, lips twisted in a snarl; "I'm not going to sit around and wait for your orders to rescue my comrades. You're taking too damn long to do anything, and my comrades are falling one by one against Academia's forces."

"Are you done?" Reiji asked sternly, Shun's mouth clamping shut. After a few seconds of silence, Reiji sat back in his chair, lacing his fingers together and crossing his legs. "You are not the only one who has been losing people to Academia. However, the statements I gave to you the night we met were the terms you agreed to, and there is no room for negotiation… unless your comrades really mean little to nothing to you."

Shun shook in anger, hands balling into fists. "Shut up! What the hell do you know!?"

Reiji shot him a glare. "Enough to know you are powerless against my father and that you're dependent on my captivity to ensure the return of your comrades."

The other man remained standing there, mouth open but no words coming out of them. What a pain this was to the both of them. They could hardly stand each other (and it amazes them both that they could even be in the same room together). Shun closed his jaws and stared long and hard at the other, unsure of what to do or say next.

"If you think I'm about to let you outside after what happened," the CEO replied first, "you're sadly mistaken, Kurosaki."

Shun narrowed his eyes, retracting his hands and standing straight with a smirk. "You're the one mistaken if you think you can keep me locked up in here all the time."

"Is that so?"

"Obviously," the Xyz duelist scoffed. "Your idiot security guards couldn't even stop that Academia kid from leaving the ward that night, nor could they capture Yuto when he escaped. What makes you think they'll contain me?"

Reiji tapped his cheek with a finger, studying Shun's face. "… I don't think it. I know you can take them out. But antagonize me enough, and I won't tell you what happened to Yuto."

Shun's face fell (much to Reiji's delight) and anger once again took over. "So you do know! Why do you hide it from me!? Yuto is my last comrade, and I'd be damned if I let anything happen to him!"

"It's in everybody's best interest that you don't find out just yet. Let's leave it at that for now."

Now that was a line Shun was just waiting for Reiji to cross. And he finally did. Shun stormed behind the desk Reiji sat at and grabbed ahold of his shoulders. Reiji had enough time to flinch but not enough to fight back against the other, who pushed the chair away from the desk and threw the CEO onto the floor. The gray haired boy landed hard on his shoulder, groaning in pain and trying to recover quickly enough to react to anything else Shun does. He lifted himself up onto his elbows and leered up at the man towering him, teeth clenched tightly. He hadn't felt such a huge rush of adrenaline in what felt like years, and he didn't know what to do with it. Lucky for him, Shun wasn't actively attacking him.

"There's nothing stopping me from turning you into a card, Akaba," Shun seethed, walking over to him and pressing a foot to the other's abdomen. "Sure I challenged you to a duel, but I'm getting tired of looking at your face. Maybe I should just get this over and done with."

Reiji bit his tongue until he chose his words carefully, continuing to speak. "If I were to tell you what happened that night, chances are, things between you and I and you and Academia would be much different, and not in a good way."

Shun paused, relieving some pressure from his foot on Reiji's chest and bending over a bit. "… Explain."

"I can't do that, Kurosaki. You just have to take my word for it."

"Don't give me that crap!" Shun swung his hand and slapped Reiji square in the cheek, the cracking sound echoing across the room and Reiji's glasses flying off his face. The lens cracked as they landed, and Reiji brought a hand to the flushed cheek, eyeing his spectacles before looking back up at an infuriated Shun. "Is Yuto alright? Did he die? Was he taken prisoner by Academia or that Synchro bastard? Answer me!"

At this point Reiji was fed up with Shun's defiant and unruly behavior, but at the same time, he felt empathetic for him. There was a tone of desperation in Shun's voice and Reiji assumed that it was because he knew. He knew Yuto was in trouble, and he knew he was probably the last stronghold against Academia's forces. But still, there was a difference in feelings between knowing it before and after verification. For Shun's sake (and Reiji's too), it was best he didn't hear those words.

The silence irritated the Xyz duelist and he growled, returning the force he took away from his foot against the CEO. "Give me one good reason why I shouldn't card you right now, Akaba."

Reiji glanced down at Shun's foot and shoved it away with his arm, causing the other to lose balance for a short time. That was more than enough for Reiji to lunge at him and grab his coat, dragging him down on top of him. Shun yelped in surprise, dropping onto his knees and barely catching himself before he slammed into the boy below him. "I can't do that either," Reiji spoke calmly, releasing Shun's coat and using that freed hand to tilt the other's head up to look him in the eye. They were merely inches apart, but that didn't seem to bother either of them. "I can assure you, though, that you are not fighting Academia alone. You may have antagonized me thanks to your attacking those of my corporation, but I am a firm believer in "the enemy of my enemy is my friend." I am just as eager at taking Leo Akaba down as you are."

"Doesn't seem like it," Shun grumbled, averting his gaze when realization hits him.

Reiji smiled slightly, hand still in contact with Shun's skin. He took his jaw in his hand and steered him closer, pulling him into a kiss. He ignored the sound of surprise and disgust from the other boy, but did notice the other's lack of will to pull away… so he did so himself after a few seconds, smirking at the wide eyes and red face Shun had. "I must say, though. You're extremely irresistible when you're angry."

"Wha…! Y-you-!" Shun was unable to formulate clear sentences, sputtering and finding something appropriate to say to the boy who kissed him. Damn this idiot! Damn the stupid smirk on his face, damn that knowing look in his gorgeous purple eyes, damn his… fuck! Now he wasn't thinking clearly. His face burned with embarrassment and anger, and he swore under his breath as Reiji laughed in amusement.

"How cute," The CEO commented as he tightened his grip on Shun's jaw and pulled him in to press his lips against the corner of his mouth. "Come now. I can't imagine the dark and rebellious Kurosaki to be so submissive and shy when it comes to something like this."

Shun growled a bit, trying not to blush as hard as he was. "Shut up. And stop kissing me. That's disgusting."

"Then how about you calm down and get yourself together before you do something you regret?" Reiji asked, arching a brow.

"Like let you kiss me? Yeah, I regret that already."

Reiji chuckled softly. "Are you sure? You're not pulling away from me."

Shun paused for another moment, a sound suggesting annoyance reverberating in his throat. He did want to pull away, he definitely did. But his body refused to obey him. And curse it- Reiji grabbed him by the back of the head and kissed him more, nibbling on his lower lip and tangling his fingers in his hair. And oh hell, did that feel good. Sure he was kissing awkwardly because he refused to return them, but the feeling of his hair being tussled and pulled around... Something about that just sent shivers down his spine and excited him.

Reiji lifted himself up some more and used the tips of his fingers to gently push Shun off of him and guide him onto the floor, surprised to see the other complying. "Your breathing is becoming rigid. Tell me, Kurosaki… are you enjoying this?"

"Like hell I am," Shun responded flatly. It was a wonder how calm and collected he sounded, when he knew goosebumps were lining his skin.

"Then why aren't you trying to stop me?"

Shun didn't know. He didn't know at all. He bit on the inside of his cheek and averted his gaze, not wanting to see the grin he knew made its way onto Reiji's lips. "… Just do what you want. I want to get it over with."

"Are you sure?" The CEO asked, patiently watching and waiting for the Xyz boy's answer. "There's no going back if you say yes."

"… Yeah."

Reiji hummed softly, leaning in for another kiss. Shun still didn't respond to it, so Reiji grabbed onto his face with his hand and pressed his fingers into the boy's cheeks to separate his jaws. Shun made a little noise of protest and instantly froze as Reiji slipped his tongue past his lips, squirming and finally reacting to the kiss (negatively, of course). Reiji was surprisingly strong and didn't release his grip, no matter how hard Shun struggled. His tongue wrapped itself around Shun's, gliding along its rough surface and taking in the taste of his mouth. He immersed himself into the reluctant boy's soft noises, finding them both adorable and arousing. The Xyz duelist quickly ran out of breath and panted noisily whenever their lips began to part, and Reiji found himself breathing harder as well. He finally released him when he ran out of breath, Shun gasping audibly as he shoved him away.

"What the hell was that, Akaba?" He growled, chest heaving and hand lifting to his mouth.

Reiji arched a brow. "Inexperienced, are we? How sad. Someone with looks like yours should have at least had an opportunity or two to explore these sorts of things."

What did that mean? Shun wiped his mouth on his hand, leering at the other. "You mean to tell me you've done this before?"

"Perhaps, perhaps not." Reiji crawled over the other and pressed him onto the floor with his hand. "Now remove your scarf."

Shun blinked, body tensing. "What? Why?"

"Don't question it, Kurosaki. Just do it."

So now this idiot son of Leo thought he was in charge? The level but demanding tone in his voice was more than enough to tell Shun Reiji wanted to assume control. How infuriating. But part of him wanted to see how far the other could go, wondering how he would act when he felt dominant. And as much as Shun loathed the thought of playing the submissive role to this bastard, it was worth tapping into...

Damn. When did he start thinking this way, and why?

Shun complied with the orders, unraveling the red cloth around his neck and tossing it down to the floor. He leaned his head back a bit, sighing softly but nervously as the usually covered skin was exposed to the cold air. Reiji could hear the shuddering in his breath, leaning in and pressing his lips to the other's neck. "Good boy. Now just relax. You'll find yourself enjoying this, I assure you."

For now he'll take his word for it. Shun dug his fingernails into the carpet, the light feathery kisses making him shiver and his eyelids flutter closed. Reiji's mouth opened wider to suck on the skin at the base of his neck, soliciting a gasp and small whine from him. Why did it feel this way? It was strange, but nice, and he wanted to feel more of it… until:

"Augh! H-hey, Akaba!" Shun growled, grabbing a fistful of the CEO's hair and yanking his head back. "What the hell was that!? That hurt!"

Reiji flinched a little as he was forced back but remained patient with the other, calmly licking up the excess saliva off his lips. "I'm marking what's mine. You'll have to get used to it, there will be plenty more across your body once I'm done with you."

Shun opened his mouth to protest, but snapped it shut as Reiji got back to sucking. He forced himself to sit through it, finding it not as unpleasant as it first seemed. There was the occasional discomfort, but other than that, it actually felt really good. The next thing he knew, his torso felt cold, causing him to glance down and slightly gasp at his undone jacket and lifted shirt. When did Reiji do that, and how did Shun not notice before? The CEO went back to sucking and leaving bruises along his body, Shun feeling them the most along his collarbone, shoulders, and abdomen. Especially the stomach; the rebel squirmed and held onto Reiji's hair, teeth clenched and voice sounding strangled, "Akaba…! S-stop, that hurts!"

Reiji glanced up at him, licking the sensitive spot. "Hm? Don't tell me this is all the pain you can handle. Your threshold is disappointing for someone who's been in war."

"Shut up," Shun growled, tightening his grip on a fistful of the other's hair. Reiji just grinned and waited to be released, resuming caressing the skin with his tongue.

"Relax. They'll feel much better after this, I assure you."

Shun didn't trust him, but sighed and laid back anyway. He wonder how his body looked, sprinkled with red and purple marks all over it. If the chance came to turn the tables on him, he sure as hell was going to give back what he received, but ten times more. But for now, he'll let Reiji have his fun… He glanced down to see his shirt slipping down on some occasions, motioning for the other to stop so he could remove it and cast it aside. Once he did, he laid back down on the floor, letting out a small sigh.

Reiji waited for him to relax again before sliding himself up the XYZ rebel's body, settling at his chest. When he regained the other's attention, he opened his mouth again to begin sucking on his right nipple. Shun's breath hitched in his throat and he fought hard to stifle a moan, surprised at how amazing it felt. He wouldn't dare give Reiji the satisfaction of having him submit so easily (but boy, was he losing it and fast). The CEO teased the puckered skin with the tip of his tongue, coating it in saliva and gently nipping it with his teeth. Shun did all that he could not to make a sound, but his body definitely betrayed him, squirming and arching itself as the teasing ensued. It obviously didn't go unnoticed either, as Reiji slipped an arm under the arch to pull him in even closer, his other hand lifting to play with his other nipple.

Damn, that was too much. He couldn't help himself anymore. Shun kicked his legs a bit and sighed audibly, whimpering at the pleasing feeling that radiated from his core to the rest of his body (and down below).

Reiji didn't stop there, deciding to pull away from the pert skin and press his lips on the area above it, deciding to mark him there as well. Shun's fingernails dug into the CEO's scalp as he cried out, realizing the mistake he made and clamping his mouth shut. Reiji chuckled, lifting his head back up. "Enjoying yourself, Kurosaki?"

The XYZ duelist knew his face was a bright red, and though he wanted to bark out a loud "no," he knew it was a lie. He was giving in, and Reiji knew it too. There was only so much more of this teasing he could take. All he could do was bite on his lip in response, averting his gaze.

The CEO pushed himself back up to sit on his legs, wiping his mouth on his sleeve. "I'll take that as a yes," he responded calmly with a smile, not taking his eyes off of him. He wasted no time with removing Shun's trousers, discarding the belt and slipping his pants and underwear down to his ankles. Shun covered his mouth as he glanced down, face burning in shame upon realizing how hard he had become. Now there really was no denying his pleasure.

"Mm, Kurosaki," Reiji murmured softly, with a new but seducing tone in his voice that Shun found himself instantly melting for. "You're quite hard already. Let's see how long it will take for you to orgasm."

"… W-wait, what are you going to- Ah!" Shun gasped and tossed his head back, the tip of his member encompassed by the familiar moist warmth of Reiji's mouth. He could feel the tongue flick and dance along his skin, and Shun moaned at the touch, arching his back in response and covering his face in the crook of his wrist. "Oh fuck, I… that feels so good…"

The CEO opened his mouth wider and took more of the other boy's member in, sucking ever so gently but coating the skin in his saliva. His tongue wrapped around the length and slowly slid back and forth, eliciting a few more small sounds from the rebel. Oh how glorious it was to have someone melting for him, losing control and reliant on him for pleasure. He hummed softly, the reverberation in his throat and mouth sending vibrations coursing up Shun's body.

Shun gasped and groaned again, head rolling back and eyes half lidded. "Fuuuck, more… faster, please…!" He couldn't care less that he was on the brink of begging. It was practically sinful to feel this amazing, and there was no way in hell he wanted him to stop now. The gray haired boy delivered, and Shun's breathing became even more rigid, mouth hanging open and toes curling. "Mmh, yes, like that! Oh, Reiji…"

The boy sucking on him stopped, pulling his mouth away and letting the cool air hit the wet skin (leaving Shun to whine in discontent). "Kurosaki. Did I hear correctly, just now?"

It took a while for the rebel leader to compose his thoughts, blushing madly at how submissive he must have looked to the other. "W-what?"

"You called me by my first name."

Shun blinked, legs slowly closing. "I… did? I don't remember…"

Reiji shoved a hand inside Shun's thighs to separate his legs, making sure they don't touch. "Hm. I suppose I'll just have to make you do it again." And with that he lowered himself back down, kissing along the thighs back down to his core, where he took Shun into his mouth again and resumed sucking.

Holy fuck, he couldn't bear it anymore. Shun's hips buckled around Reiji's head, preventing him from bobbing up and down along his length (only for the CEO to force his legs apart again to continue). The only sounds that filled the room were the sounds of Reiji sucking and Shun's moans and cries, both growing louder and louder. "Ahh… fuck, Reiji…! Faster, faster… I- ngh!" He was cut off momentarily thanks to a small raking sensation of Reiji's teeth on his skin, but that didn't stop him altogether. "Reiji, I can't take it anymore…!"

Reiji pulled his mouth away again, licking along the tip of the other's member. "Then don't. Go ahead and release, and moan my name when you do." He waited for a nod in acknowledgement as he took him back in, picking up the pace of his sucking and forcing all of Shun into his mouth, though he almost choked when he did so.

It was too much. Shun practically threw his head back as he screamed, back arched and mouth hung wide open as he finally climaxed. "Oh God, Reiji…! Reiji, augh!" His hearing temporarily faded and the coil in his stomach snapped, eyes rolling back and a groan escaping his lips as an overwhelming wave of pleasure overtook him. He couldn't think, couldn't do anything, but let himself enjoy the feeling that swept over him. As he slowly descended from his high, his body went lax and he laid on the floor, panting heavily and gathering his scattered thoughts. Dear Lord, he was drenched in sweat, his hair clung to his face and neck, and... was that drool leaking from his mouth?

Reiji sat up and swallowed the seed Shun released from his orgasm, wiping his own saliva-covered mouth dry. "How do you feel, Kurosaki?" He received an aversion of Shun's gaze and a red face in reply, making him chuckle. "At least you enjoyed yourself."

"… I'm a mess now, though," he commented, voice a little hoarse from his constant shouts and cries. "… You don't mind if I shower, do you?"

"Not at all." Reiji stood up and admired the view of the other from above, smirking. "Now go, before Nakajima comes in and sees you like this."

Shun blushed harder and sat up on his elbows, gazing tiredly at the clothes thrown beside him. "… Yeah… thanks, Akaba."

"What, no more calling me by my first name?"

Shun glared as the CEO laughed, but couldn't respond. Hell no. Definitely not now, now that Reiji's first name would forever be laced to the ideas and fact that he would say it so much more during this activity. He knew this was just the very beginning of whatever the CEO, his assumed master, had in store for him.
