Work Text:
The first time Akutagawa noticed the ears, it was because one of them twitched.
Not that he’d been staring (He had). Not that his fingers itched to touch the soft-looking fur (They did). And certainly not that his stomach did something embarrassingly warm whenever Atsushi’s tail flicked absently behind him, like a lazy pendulum (It was treasonous).
They were in one of the Agencyʼs secondary safe houses, a small, sunlit room with a worn couch and the smell of old books. Atsushi had stopped by to deliver a report, and for reasons neither of them had questioned, heʼd stayed.
His abilities were active; sometimes, after particularly draining missions, his body defaulted to this half-shifted state, ears and tail persisting even when the rest of him had returned to normal.
Right now, he was sitting cross-legged on the floor, paging through a file, and his tail curled and uncurled behind him in slow, hypnotic motions. The late afternoon light caught the white fur, turning it luminous.
Akutagawa sat rigid on the couch. He was absolutely not watching the way Atsushiʼs left ear swiveled toward the window when a bird sang outside. He was not noticing how the fur at the tips was slightly longer, feather-soft and pale. He was a trained mafioso, a ruthless ability user, a man who had faced death without flinching, and he was being undone by fluff.
His throat felt dry. He swallowed.
“Atsushi.” The word came out rougher than intended, and Akutagawa winced internally. So much for composure.
Atsushiʼs head lifted, those purple-gold eyes finding him with open curiosity. One ear rotated toward him, a silent, devastating acknowledgement that every small sound had his attention.
“What is it?”
Akutagawaʼs mouth opened. Closed. He felt heat climbing his neck, which was absurd, because Akutagawa did not blush. He glared at the floor as though it had personally offended him.
“Your—” He stopped. Tried again. “The ears.” The words were clipped, strained.
“They look... soft.”
The avowal hung in the air like a murder confession, except worse, because murder was something he could handle with dignity. This was just... pathetic. He could feel his pulse hammering against his throat, and he refused, refused, to meet Atsushiʼs gaze.
For a long moment, silence stretched between them. Then, soft, so soft Akutagawa almost missed it, came a quiet exhale of surprise. He risked a glance upward and found Atsushi staring at him with an expression caught somewhere between confusion and cautious hope, head tilted slightly to the side.
The movement made his ears flop forward just a fraction, and Akutagawaʼs fingers twitched against his thigh.
“Do you...” Atsushi began, and then his expression shifted, warmer, almost teasing. A small smile tugged at the corner of his mouth.
“Do you want to touch them?”
Akutagawaʼs composure shattered into a thousand irreparable pieces.
“I— No.” The denial came too fast, too defensive, and they both knew it. He could feel the heat spreading to his cheekbones now, traitorous and obvious against his pale skin.
“It was merely an observation. The tactile quality of your transformed state is irrelevant to—” He was babbling. He, Ryuunosuke Akutagawa, was babbling. About fur. He wanted to dissolve into liquid and disappear forever.
Atsushiʼs smile only widened, and there was something insufferably knowing in it. He shifted where he sat, turning to face Akutagawa more fully, and his tail swished behind him in a slow, lazy arc.
“Itʼs okay,” he said, and his voice held none of the sharpness their exchanges usually carried.
“I donʼt mind. If you wanted to... you know.” He tilted his head again, and one ear flopped artlessly to the side.
“Theyʼre pretty sensitive, but I trust you.”
The last three words landed somewhere in Akutagawaʼs chest and detonated. He stared at Atsushi, at the genuine openness in those dual-colored eyes, at the way heʼd said it so simply, as though trust were something freely given rather than earned in blood, and something in him cracked cleanly in two.
His hands curled into fists on his knees. His jaw tightened. He was a man of discipline and control, and he would not allow himself to behave like a child presented with a beloved pet. He would not.
“...Fine.” The word escaped through his teeth, barely audible. Atsushiʼs ear twitched again, tracking the sound, and Akutagawaʼs resolve crumbled entirely.
“May I—” He stopped. Swallowed. Forced the words out through sheer force of will, his pride dying a quiet death in the corner.
“May I touch them?”
Atsushiʼs expression softened into something impossibly fond. He shifted closer, rising onto his knees to bring himself within armʼs reach of the couch, and the movement made his tail curl upward in a graceful, relaxed arch.
“Go ahead,” he murmured, and the invitation was so simple, so earnest, that Akutagawa forgot how to breathe for a moment.
He stared at the ears, really stared, taking in the way the white fur caught the light, the delicate pink skin visible beneath the thinner hair at the base, the way they swiveled slightly toward him, tracking his every micro-expression.
His hand rose with all the hesitant caution of a man approaching a live wire.
The first brush of his fingertips against the fur stole the air from his lungs. It was soft, impossibly, ridiculously soft, like touching a cloud made tangible, like something dreamed rather than real.
Akutagawaʼs breath caught audibly, and his eyes went wide. The fur was thick and plush beneath his touch, warm from Atsushiʼs body heat, and when his fingers curled slightly to stroke from base to tip, the ear twitched and leaned into his palm.
A quiet, involuntary sound escaped Akutagawaʼs throat, something dangerously close to a whine, and he felt his entire face go hot with mortification.
And then Atsushi purred.
The sound was low and rumbling, a continuous vibration that seemed to emanate from somewhere deep in Atsushiʼs chest. It filled the quiet room like a gentle tide, and Akutagawa's hand froze mid-stroke, his grey eyes going wide with something dangerously close to wonder.
The purring intensified when his fingers remained in place, and Atsushiʼs eyes drifted half-closed, his whole body leaning imperceptibly into the contact. His tail had gone lax and heavy, swaying in slow, contented arcs behind him.
“Sorry,” Atsushi murmured, his voice thick and hazy, “that happens sometimes. Canʼt really control it.” He didnʼt sound sorry at all. He sounded pleased, and the realization made Akutagawaʼs chest constrict painfully.
Akutagawaʼs other hand rose without his permission, trembling slightly as it found the second ear, and then he was cradling both, stroking, exploring, mapping the silken texture with growing boldness.
The purring deepened into something resonant and warm, and Atsushiʼs head tilted into his palms like he couldnʼt help himself, chasing the touch.
Akutagawa felt his own expression shifting, felt the rigid control heʼd maintained for years splintering at the edges, but he couldnʼt bring himself to care. This was soft. This was warm. This was Atsushi, trusting and open and making sounds of contentment because of him, and without his consent, without his awareness, his lips curved into a genuine smile.
It was small and trembling, fragile, nothing like the cruel smirks he wielded as weapons. His eyes had gone soft, his features unguarded in a way they hadnʼt been since forever, and he looked, happy. Genuinely, uncomplicatedly happy.
The realization hit him a heartbeat too late, and then Atsushiʼs eyes fluttered open, hazy and warm, and landed directly on Akutagawaʼs face. His expression flickered with surprise before melting into something impossibly tender.
“Akutagawa,” he breathed, and the use of his given name sent a jolt through Akutagawa's chest, “youʼre smiling.”
The words struck like a lightning bolt. Akutagawaʼs smile vanished so abruptly it might never have existed, his expression locking down into rigid denial even as his face burned crimson from jaw to hairline.
“I am not,” he hissed, yanking his hands back as though Atsushiʼs ears had burned him. His voice cracked on the denial, pitching higher than heʼd have liked, and he scrambled backward against the couch cushions as though he could somehow escape the evidence of his own betrayal.
“You are delusional, jinko. I have never smiled in my life. I do not smile. Smiling is—” He floundered, grasping for a suitable condemnation. “—for fools and weaklings, and I am neither.”
Atsushiʼs expression cycled through surprise, amusement, and finally settling on a warmth so devastating that Akutagawa almost looked away.
The weretigerʼs ears drooped slightly from the loss of contact, and Akutagawaʼs hands twitched violently against his thighs with the urge to reach out again.
“Akutagawa,” Atsushi said gently, unbothered by the outburst, “your face is completely red.” He shifted forward again, closing the distance Akutagawa had tried to create, and his tail curled slowly around his own waist as he moved.
“Itʼs okay. I thought it was... nice.” The admission came soft and unguarded, and Akutagawa felt his pulse stagger in response.
“You should smile more often. It suits you.”
Something in Akutagawaʼs chest seized painfully at the words, and he opened his mouth to deliver a scathing retort, but his throat closed around it. Atsushi was watching him with open affection, and the afternoon light turned his white hair luminous at the edges, and his ears were right there, still slightly tilted forward as though hoping for more attention, and Akutagawa discovered heʼd lost all ability to form coherent sentences.
Without conscious decision, his rigid posture began to unwind. He exhaled slowly, a shaky, surrendering sound, and glared at the ceiling as though it had personally orchestrated his humiliation.
“...You are insufferable,” he muttered, but the venom was gone from his voice, replaced by quiet resignation.
Atsushiʼs smile widened, and his tail swished behind him, and Akutagawa knew with sinking certainty that heʼd already lost this war.
Atsushi seemed to sense the surrender in Akutagawaʼs posture, because he moved without hesitation, rising from the floor and settling onto the couch beside him in one fluid motion. He didnʼt stop there. Before Akutagawa could protest, the weretiger had twisted and lowered himself until his head rested in Akutagawaʼs lap, white hair fanning across the dark fabric of his trousers.
The position was utterly casual, utterly trusting, and Akutagawa froze with his hands hovering uselessly in the air, unsure where to put them.
Atsushi gazed up at him with half-lidded eyes, a lazy contentment written across his features, and his tail curled over the edge of the couch, swaying in slow, rhythmic arcs.
“You can keep going,” he murmured, and the invitation was warm with expectation.
“If you want.”
Akutagawaʼs hands trembled as they lowered, one settling uncertainly on Atsushiʼs shoulder while the other found his chin with agonizing slowness.
The angle was different now, more intimate, and when his fingers began to stroke along the soft underside of Atsushiʼs jaw, the purring resumed instantly, louder and more resonant than before.
The sound vibrated through Akutagawaʼs thighs, and he found his rigid posture melting by degrees, his shoulders dropping as tension he hadnʼt realized heʼd been carrying bled away. Atsushiʼs eyes drifted fully closed, his expression one of unguarded bliss, and his ears twitched contentedly against Akutagawaʼs knee.
The safe house had grown quieter somehow, the world outside the window fading to insignificance, and Akutagawa realized with distant horror that he didnʼt want to move. Didnʼt want this to end. His thumb traced a slow path along Atsushiʼs cheekbone, and the weretiger leaned into the touch with a quiet, pleased sound that made Akutagawaʼs chest seize.
“This doesnʼt leave this room,” Akutagawa said finally, his voice rough and lacking any real threat.
His grey eyes had gone soft again despite his best efforts, and he knew, knew, that Atsushi could see the warmth he was failing to suppress. Atsushiʼs lips curved into a drowsy smile, and one eye cracked open to peer up at him with impossibly gentle amusement.
“Mmm,” he agreed, the sound more purr than word, and his tail gave a happy flick.
“Whatever you say, Ryuu.” The name landed softly, intimately, and Akutagawaʼs hand stilled for just a heartbeat before resuming its gentle rhythm.
His face burned, but he didnʼt stop. Didnʼt pull away.
Outside, the afternoon light had begun its slow descent toward evening, casting the room in shades of amber and shadow, and Akutagawa supposed, with grudging acceptance, that there were worse fates than being trapped beneath a purring weretiger who looked at him like he was something worth being gentle with.
