Enjoy.
It was truly breathtaking, Akutagawa thought, to witness the weretiger in action.
To see him tear through abilities and people like shredding paper. To feel the raw power coursing through him as he moves about the battlefield. To feel those powerful, deadly hands press him down against the soft sheets of his bed, to feel him tear both their clothes off like a starved animal.
It is not the first time he has fallen into bed with the weretiger— Atsushi, as he begged to be called during these moments— nor is it the first time he has allowed the weretiger to ravage him, to make him submit not as a display of weakness, but as an act of trust.
This is the first time Atsushi has chosen to do so not ten minutes after a fight.
It's obvious that Atsushi is still running on adrenaline, pupils dilated like a cat's and chest heaving. He backs Akutagawa up against the wall of a mildly collapsed building, clawed hands curling into the concrete by his head.
He grinds his hips against the crook of Akutagawa's thigh, mouth and tongue and teeth pressing veverishly hot against his neck as he fumbles with the buttons of his pants.
"Please," Atsushi murmurs deliriously, shallow thrusts speeding up as he finally works his hand into Akutagawa's pants. He clumsily paws at Akutagawa's cock while he gasps and whines before finally pulling his half-hard dick out of his slacks. "Ryuu, let me make you feel good, please???"
Atsushi continues to beg, hand trailing up and down his length until Akutagawa can feel tears brimming in the corners of his eyes. "Fu— Weretiger, if you don't get inside me within the next two minutes I will castrate you—"
He barely gets through the demand before Atsushi is pushing him up, forcing his legs up and away so he can tear clean through Akutagawa's pants and push his rumpled white shirt up his chest. It's a wonder Atsushi hasn't torn it off yet. His shout of anger quickly becomes a cry of shock as Atsushi drops to his knees, mouth pressing against his hole with a desperate moan.
"Thank you thank you thankyouthankyou—" Atsushi rushes out, lips brushing against where he needs him most before that ache inside him is being filled by Atsushi's warm tongue and prodding fingers.
He chokes on a sob as Atsushi rushes through prepping him, moans and praise falling from the weretiger's lips whenever he separates from Akutagawa long enough to speak. Atsushi is an impatient man, but he is also a deranged lunatic who enjoys watching Akutagawa fall apart before he's even inside.
Eventually, Atsushi's need to be inside him overpowers his desire to make Akutagawa come apart— not a moment too soon, he thinks bitterly as the edge recedes as Atsushi pulls back. Atsushi stands quickly, pushing Akutagawa up against the wall and freeing his monstrous cock in one movement.
"Can— please, Ryuu, inside??" Atsushi begs, lavishing kisses and bites against his pale neck generously. He doesn't need to ask for permission, Akutagawa shifting to rub his aching heat against Atsushi's throbbing cock.
"Of course, my weretiger," He purrs, hand coming up to tug at the short air at the base of Atsushi's head.
Atsushi responds with a snarl, hips snapping up to sheath himself inside Akutagawa in one fluid thrust.
Akutagawa can't stop the scream that tears from his throat as Atsushi slides home, cockhead pressing deliciously against his prostate. Atsushi stalls for a moment, taking deep, shaky breaths as he adjusts. It's only when Akutagawa starts to whine that he moves, pulling out and slamming back in not a second later, like he can't bear to be outside of Akutagawa's tight heat for even a moment.
"Ff— Fuck, Ryuu, look—" Atsushi sounds pained, eyes locked on Akutagawa's stomach. Akutagawa barely glances downwards before he's throwing his head back with a high-pitched keen, hand coming to rest against the visible bulge of Atsushi's cock.
Holy shit.
Atsushi's pace picks up with renewed vigor, teeth planting firmly onto his collar bone. "Tha's all me, yeah? Just me— only one who makes ya' feel this good—" Atsushi babbles, tears trailing down his cheeks— a shocking contrast to the brutal pounding he was offering Akutagawa's sensitive guts. "The only one, right? Just the two of us?" He asks quickly, pulling out to just the tip. Tease.
"Do we need— ah, anyone else?" He responds in kind, hooking his ankles behind Atsushi's back with a small groan. Atsushi huffs in amusement, hips snapping back into place. He buries his face in Akutagawa's shoulder once more, resuming his mission to leave him covered in marks.
Akutagawa hisses as his orgasm fast approaches, muscles clenching. "Ah— Atsushii—" He moans, head falling back against the wall with a frown. "Can't— close, 'm so close, I—"
"With me, Ryuu," Atsushi sighs, grinding deep inside. He takes Akutagawa's cock in hand, languidly stroking in time with his thrusts, driving Akutagawa mad with dual pleasure. "That's it— good, so— ngh— fucking perfect, all for me—" He stills, hips jerking as he unleashes his load deep inside Akutagawa's body.
Akutagawa jolts in shock, caught between moaning at the sensation of being filled and scowling at the uncomfortable feeling of cum filling him further than it should. "Weretiger," He hisses, "You insolent—!"
"Shut up, Ryuu," Atsushi sighs, resuming his strokes. He remains still inside Akutagawa, thumbing at the head of his cock with a thoughtful hum. "That's it, falling apart so perfectly for me," He smiles, kissing the tears from Akutagawa's cheeks.
Atsushi works him through his orgasm, holding him up as the pleasure fades into the comfortable ache of exhaustion and overstimulation. He scowls as Atsushi sets him down, staring at the tattered remains of his pants while he stands on shaky legs.
"C'mon," Atsushi wraps an arm around his waist cheerfully. "Let's head home and get you a bath."
Akutagawa doesn't comment on Atsushi calling his apartment "Home."
It was only a matter of time, anyway.
