The Cave of the Voiceless Wolf

“Is there a problem?” Izuku said, crossing his arms across his chest as he glared up at the other man. Tomura’s attention had been honed in on him since breakfast and Izuku had finally had enough of it. "You’ve been staring at me all morning. If you’ve got something to say to me, either say it or leave me alone."

Tomura leered down at Izuku through a half-lidded gaze, crimson eyes glinting in the soft orange lights of the hallway. Paying explicitly close attention to the way their silvery blue soul-cord looped around Izuku's pale throat over and over and over again, all nice, tight, and pretty. Right where Tomura wanted it. Right where it looked the best: wrapped around Izuku’s pale, freckled neck.

Right where it belongs, Tomura thought possessively, his cock twitching in agreement in his pants. The same it had been doing all morning long, causing him to have to constantly readjust his slacks.

The longer Tomura ogled him, the more Izuku’s frown deepened, and Tomura noticed the younger man’s glare taking on a heatedness that caused the green in his eyes to darken, contrasting beautifully against the silvery blue soul-cord wrapped around his neck.

Oh, yes. Tomura could definitely get used to this sight.

"Just admiring my handiwork," Tomura finally said, offering a wolfish grin with far too many teeth.

"Handiwork? What handiwork?" Izuku asked, brow furrowing with suspicion.

Tomura's only answer was a slight quirk of his lips.

Suddenly, Tomura thought of a wonderful idea, and his grin took on such a quality of wickedness that Izuku was immediately put on guard.

It was never a good sign when Tomura smiled like that. If that manic grin was directed at someone else, it meant someone was about to harassed, maimed, or something much worse. If it was directed at Izuku, it meant Tomura was up to something no good and Izuku, willingly or not, was about to find out exactly what that ‘something’ was.

Tomura backed away from Izuku, watching as the distance between them increased the floating length of their soul-cord. Tomura grasped the slack and gently looped it around his hand multiple times until it was almost completely pulled taut.

“What are you doing?” Izuku looked at Tomura like he’d lost his mind, what with his waving his hand around in the air like a lunatic. “Looks like you’ve finally gone completely insan—"

Without warning, Tomura roughly yanked their soul-cord towards himself, like he was yanking a dog backwards on a leash. Izuku found himself being jerked forward by an unseen force, tripping over his own two feet and nearly tumbling to the floor were it not for him crashing straight into Tomura's chest.

Izuku’s eyes widened in shock. Not only from what had just occurred but from the feeling of something warm, ticklish, and wispy stroking the length of his neck as Tomura made strange hand movements in the air.

Bewildered, Izuku ran his fingers over his Adam’s apple and around the back of his neck, where the warming sensations were the strongest. He grabbed at nothing, could feel nothing, only adding to his growing confusion at what the actual hell was going on. Did Shigaraki get a new Quirk?

Tomura hummed, seemingly delighted. He made another quick hand motion, fingers circling around nothing and making to grab at something in the air before pulling it closer.

Izuku felt it again, even stronger than before. A thick, deliciously warm pressure around his neck, not quite cutting off his air supply but toying the line of doing so. He couldn’t stop the flush from entering his cheeks at their sudden, close proximity, nor the shiver that ran down his spine at the feeling of something so snug and… protective closing in around such a vital part of his body.

Izuku bit his bottom lip, chewing at worryingly.

Tomura ate up the sight of Izuku’s nervous arousal with a quiet sort of hunger. With their soul-cord still looped around his hand, Tomura softly, ever so slightly, pulled it just a bit tighter.

Izuku gasped, pretty green eyes growing to such a comically large degree that Tomura could not help but let out a mean laugh at his expense, entertained by the younger man’s reactions.

“You!” Izuku hissed accusingly, snapping out of his stupor and narrowing his eyes into angry little slits, “What the hell did you do to me!?”

Tomura grin grew so wide and predatory it nearly split his face in half. “Maybe if you’re a good boy today and don’t get into any trouble, I’ll come by your room later tonight and tell you all about it.”

At Izuku’s utterly scandalized face, Tomura smirked. He swiftly untangled their soul-cord from his hand right as Izuku forcibly pushed against his chest, propelling himself away and out of Tomura’s grasp.

Izuku grunted from the force of his back thudding against the wall of the hallway. He splayed his hands against it and quickly but cautiously inched himself along the wall away from Tomura, mouth slightly parted as he stared at the other man with an expression that was so distrustful Tomura couldn’t help but let out a huff of amusement, his canines popping out past his cracked lips.

“D-don’t you ever do that to me again!” Izuku managed to stutter out, the words coming out way less confident and threatening than he wanted them to sound.

But god, this unhinged man-child was quite literally driving him up the wall and Izuku wanted no part of anything to do with Shigaraki Tomura.

Izuku took a couple of cautious steps backwards, regarding Tomura like he would a rabid wild animal he didn’t want to turn his back to lest it pounce on him.

Tomura just stared back, crimson eyes gazing at him with an intensity that frightened Izuku more than anything else that had just transpired between them.

Izuku noped out and made a break for it.

"Must be hard for people to say no to the elusive, all-powerful, all-mighty Avatar,” Zuko says playfully, wiggling his brows as he stares at the ceiling.  

“Whatever!” Aang waves it away with a laugh, then narrows his eyes amusedly. “Why, are you jealous?” 

“Aang.” He says flatly, somewhere between a clear joke and not a joke at all.  

“No, come on. Not like that!” Aang says, a wide smile turning into a mockingly serious face. “Jealous that you don’t have as much freedom. Or time. To... explore, I guess?”  

“You know I’m jealous of your freedom, asshole.” Zuko crumples up a scrap of parchment and throws it at him. “Rub it in, go ahead.” Zuko laughs as Aang winces at the paper smacking him on the temple.  

Shoulders still shaking with amusement, Aang adds, “Well you’ve got some time now. Have you ever been curious?” 

Zuko ponders for a moment before admitting, “A little,” with a shrug.  

“Well, then, lock the door and come over here,” Aang says, bright and friendly as he always was.  

“What?” Zuko half laughs half says, sitting up sharply, hands bracing the chair on either side of his thighs as he pins Aang with a questioning look.  

“What, what?” he says, cocking his head to the side, “When was the last time you had a full week of no obligations? Never try, never know.” He says like it’s as simple as 2+2. “Oh come on, Zuko, you’re acting like we haven’t shared a bed a thousand times or seen each other naked a thousand more than that.”  

Considering it all, Zuko’s knee bounces up and down, “Yeah, but don’t you think fucking is in a different category?”  

Aang shrugs, “I was raised a little differently when it comes to that. To me, it can be but it doesn’t necessarily have to be. If it is for you, it’s no big deal. No pressure.” He waves a hand rolling onto his back and throwing his hands behind his head.

Eyes dancing over Aang watchfully, Zuko chews his bottom lip and thinks. He has been curious, and Aang is right: he doesn’t have as much freedom or time, every detail of his life is planned out for him. When would he find time to go discover if he likes fucking men or not? And with Aang... Aang is his best friend, of course. They do everything together. They’ve done everything together- their professional lives, their personal lives, the lines are so blurred they are nearly nonexistent. They even usually took each other as plus ones to weddings and other official events. Even when they were still dating Katara and Mai. Neither of them ever minded, because it just made sense. They made sense. They always had. They had each other's backs as diplomats, they kept each other's secrets, and they shared nearly everything. After 8 years of that- what's a little fooling around really going to change?  

Plus, Zuko could admit, objectively, Aang was hot. Not the scrawny kid he met years ago, Zuko amicably admired how rigidly muscular and surprisingly tall Aang had become as an adult. He watched fondly as Aang had grown up alongside him into a thoughtful, charming, and whip-smart leader. He understood the appeal. And on top of that, Aang was experienced. And, as Aang’s best friend, Zuko knew, with a startling amount of detail, just how experienced he was. He knew Aang would be gentle with him, and like everything else they did together- he knew he’d at least enjoy himself. 

Bouncing knee coming to a halt, Zuko says, “Okay.”  

“Okay?” Aang face flashes brightly before he furrows his brow and says, “Wait, are you sure?”  

Standing, shoulders shaking with the strange comedy of it as he pads to the door, Zuko turns the lock then turns around and says, “Yes, I’m sure. Now come over here and fuck me before I change my mind.”  

Aang quirks an eyebrow over pink-tinged cheeks and says low and slow, “Yes, sir.”  As he walks toward the bed, he shirks his shoulder to let his sash slump off, bare chest already flushed a soft pink with the summer heat. “Although, for your first time, I wouldn’t suggest bottoming. Learned that the hard way.” He says with a wince before meeting Zuko at the edge of the bed, hands instinctively on his waist in a way that feels somewhere right between very weird and very comfortable. With their faces just a breath away from one another, Aang says, “You should probably fuck me this time.”  

“You’re planning on another time?” Zuko jests before throwing his arms over Aang’s shoulders.  

“I don’t know, depends on how good it is.” Aang retorts. 

Zuko rolls his eyes, then adds, “Okay, one rule.” 

“What is it?”  

“Don’t kiss me on the mouth,” Zuko says easily, almost laughing because fuck if this whole thing wasn’t hysterical. “I feel like that’s self-explanatory.”  

“Works for me,” he confirms like it’s any ordinary thing- like he’s ordering dumplings from a stall in the city. “Any other rules?”  

He pulls Aang close, bodies now brushing, and says, “Keep your expectations low?”  

"Unfortunately my expectations are already completely unattainable,” Aang teases, untying one knot after the next of Zuko’s tunic as he goes, “I’m expecting demigod Agni-incarnate levels of fucking. I’m expecting to not know up from down and left from right after you rearrange my insides with your Firelord-ly, rumored-to-be-prodigiously-large dick. I’m expecting that when this is over, I won’t remember my own name.”  

Rolling his eyes with a scoff, Zuko slides one hand into the place where the fabric of Aang’s trousers rests against the skin of his waist. He tugs hard, crashing Aang’s hips to his. “Will you shut up already?” Zuko says defiantly as he shoves a hand beneath Aang’s waistband.
