The last thing you could have expected when you'd gotten in a relationship with the Agency's notoriously nervous weretiger was the very idea of some kind of breeding kink in that feral brain of his. You'd never realized it, but that tiger instinct deep inside becomes stronger and stronger the more that he becomes bonded to it, until Byakko (and yes, Byakko is a she, and she will always be a separate entity to Atsushi in this house. You will love it.) eventually learns to tap into that primal part of his brain.
Now, you and Atsushi have discussed it, and you've agreed to hold off on the idea of kids at this time—whether biological or adopted. I mean, have you seen the state of his job right now? How is he really supposed to raise a kid on sparse paychecks? Or what happens if his job takes him away from home for a few weeks or months, or—worse yet—if he should be killed in action? He wouldn’t do that to a kid, and certainly not to you. He wants to raise a child infinitely better than how he’d been treated, and, so, children are a no-go right now.
But, you don’t necessarily have to want children to indulge in a little bit of a breeding. So, don’t worry about whether you can’t by certain biology or by genetic factors/infertility, or if you choose to settle for contraceptives, Atsushi would never shame you for that. And if none of this applies, he'll be responsible and respectful and slip a condom on it. (He may be a beast, but he's not a monster.) That said, it just means he’ll try his absolute hardest all the same. Don't expect to feel your hips or thighs anytime afterwards.
If you aren't limping, then he clearly didn't do his job.
And you've learned quickly that he will fix that.
The idea of you rounded with his cubs kids gets that little primal feline part of his brain absolutely pumping—as well as blood pumping to some other places I might mention, but I digress. Some part of him is practically clawing the walls in desperation. He needs it so bad. Byakko isn't helping in the slightest as she purrs away in his mind, seducing him with imagery or wild fantasies of you knocked up and glowing—again, despite whether you can be or not.
Honestly, he’d rather join Dazai on a suicide pact and go tumbling over the nearest bridge than ever admit that to you, but damn if it doesn’t drive him nuts.
Please just let him pump one load into you—just the one! That's all he needs! Just one!
Or two…
Or three.
Actually, you know, just let him fill you so full that you’ll be dripping with him for days. After that, he’ll pump some more into you until all you can feel is him in just about every part of your body.
He’ll apologize for it later, he swears. Just, please, one more.
You can do it; You can take one more. For him. For you. For the cubs feral beast prowling around in his head that’s just roaring to fill fill fill—
He’s sorry…mostly.
And, one night--of course--as his hips slammed against you so hard that you're surprised the bed hadn't broken under all of the pressure.

"A-Atsushi.” You’d lost track of the amount of times his name had tumbled from your lips at this point—too deep into this feverish exchange of heat, sweat, and sex to even be able to clearly anymore. It was a miracle you could still think at all as his cock hammered in and out of your slick hole, dragging almost deliciously against your trembling walls. “You have to slow down."
Heavy breaths and moans were forced from your lungs with each sharp thrust against your hips, the hands around them digging so deep into the skin that there wasn't a single doubt in your mind that there would be dark marks later. Marks that he would certainly be frantically apologizing for once this haze cleared from his head.
Right now, though? Marks were all he wanted to leave. It was obvious in the way he grappled you closer against his body, a mess of teeth and tongue laving over the skin of your shoulders and neck with a bruising intensity. You could practically hear the straining of his jaw as he fought off the need to sink his fangs in and lay claim.
Instead, the harsh nips turned to soft whimpers and gasps crashing against your eardrum. Atsushi's body crowded yours against the mattress even more, pressing you further into submission under his ruthless pounding. The silver strands of his side lock tickled along the back of your neck, nearly drawing a laugh if all your attention wasn’t already drawn to the repetitive, audible 'squelch' from between your legs. Cum was pushed deeper inside while also oozing out around his throbbing cock and trailing along your inner thighs to collect in a little depraved puddle on the bedsheets—judging by its size, you were starting to question just how many rounds had you gone through already.
" ‘M sorry," he practically sobbed, hips stuttering against yours for just a moment as he desperately fought to keep his mind above the rising water of his needs. "I'm sorry, sweetheart. Just a little more, please. J-Just one more. Just one, and then I'll be done. That’s all I n-need, promise. You can take it, right? I know you can—you always can." The lustful assurance (more so for him at this point) sprang off his dry tongue as a needy, wanton plea—hands pulling up against the plushness of your hips to shift them impossibly closer against his thrusts. “D-Doing so good for me. Always so good for me.”
The babbled praise—along with the way you could practically feel him in your very lungs—had your mind blanking as stars exploded across your vision. You could barely register the sound of your own warbling moan as you crested, body tensing and tightening down around him. A low groan vibrated against the skin of your shoulder. Atsushi could barely think straight as he felt your walls flutter and squeeze his cock oh so nicely, coaxing him to spill everything he had left into you—and he was nothing if not dangerously determined.
“Y-Yes! So good—Shit!” He panted, pressing your body up against his so that his chest was flush to the sweat-soaked skin of your back. The murmured praises continued against your shoulder. “Thank you, thank you, sweetheart. I-I promise you it’ll all be worth it. Just a bit longer. Just a little bit more.” He crooned, thrusts growing uneven while still keeping their bruising force.
All you could think about, though, was his words rattling around in your head. He said one more, but if you had a nickel for every-time you heard that, you’d be on a damn yacht by now and enjoying the sea breeze—not being humped and pumped by a feral Weretiger.
So, naturally, you doubted he really meant 'just one more' at this point in time.
Heavy, wet kisses along the back of your flushed neck instantly pulled you from your thoughts. Above you, you could feel that Atsushi was losing himself more and more as he whimpered and shuddered, fangs poking past his upper lip to tease at your sweat-soaked skin. His tongue darted out and you felt his entire body tremble. A rumble built up deep in his chest as his nipping turned more incessant, hips driving further and drawing out muffled moans against the pillow under you.
He wanted so badly to simply dig in—to claim you wholly as his own.
To mark you. To mate you. To breed you.
To show you he was worthy of everything you had to offer. His jaw ached and burned with the urge to sink into the flushed skin of your shoulder; His whole body burned as he fought against the rising instincts.
And while you knew he wouldn’t do it just yet, out of his deep-seated fear of ever causing you harm, you understood that the need wouldn’t simply dissipate out of him.
And you were right. His movements began to make up for the frustration, hips slamming at an inhuman pace against your ass. His balls caught against your cum-soaked skin with every plunge of his weeping cock, sticking for just a moment before falling back as he pulled back rhythmically. It was lewd — depraved even, how you were beginning to want him to fill you just as desperately as he wished to do so.
Without warning, Atsushi's hands shifted from your hips. They sunk—instead—into the plushness of the mattress on either side of your body, as if to cage you in. A growl built deep in his chest, crowding you further down against the sheets. You could hear as his claws extended into the plushness beneath you both. The cloth gave way easily under the sharpness, filling your ears with a soft but clear hiss of ripping cloth—he was getting close.
"Atsushi," You once again moaned, voice growing weary and hoarse with over-use. You needed a break—or at least for him to settle down for a good hour while your brain tried to remember how to function like the major organ it was supposed to be. Forget adding 2+2 at this point—all you knew was him + a few more hours was going to equal a fucking coma at this pace.
His only answer to you was a heavy chuff before he dug his claws in further against the blanket, nose burying into the back of your neck. There was the sound of a shaky, deep inhale, and he was finally spilling into you for the umpteenth time tonight. The gifted-user’s body weighed heavy against yours, pushing you further down into the sheets as he teethed at the skin on the nape of your neck—no doubt wanting to grab on with his fangs and never let go.
When the sensation of his sharp canines finally disappeared from your skin—replaced now by soothing kisses and affirming words—he seemed to find his voice.
“A-Are you alright? Nothing hurts, does it?” His voice may have been raspy, but his words still help that ever present concern you’d come to love from the Tiger-boy. Always seeking to ensure your comfort before tending to his own—it was sweet. At least, you’d have said as much, if your mind was a bit more useful at the moment. Instead, you simply shook your head wordlessly. You didn’t trust your voice to carry any words right now.
He didn’t seem to mind this, though. Instead, he busied himself with showering every mark and bite in gentle touches and soothing presses of his lips. “I’m sorry I was so rough…I’ll make it up to you with some crepes after this, I promise. A-As many as you want. Unless you want something else! Ice cream, Dango, Tayaki—anything you want, just say the word.”
A breathy laugh tumbled from your lips before you could stop it. He was so sweet, that you’re positive you could feel cavities forming at the very sound of him rambling. “Crepes sound great, Atsushi.” Reaching a hand up, you slid it in along the sweat soaked hairs on the back of his neck and scratched. Instantly, he leaned into the gesture—and further down into you—with a soft, blissful sigh. You could imagine his eyes fluttering shut as he melted into the feeling. It was almost enough to make you want to lay there for the rest of the night.
But, you were honestly so ready to just dive into a bath right now. You could already feel his fluids cooling against your thighs, and you tried not to think about what it might be like when it dried and caked against your skin.
You…really tried not to think about it.
So, believing that he might’ve actually kept his word at just that ‘one last round’, you began to shift your hands under you and shakily push yourself up from the bed. You could already imagine the warmth around your shoulders at the thought of sinking into the water—blissfully relaxing as the heat soothed each ache and pain and bruise.
And you were so close to that being a reality.
Until a hand between your shoulder blades stilled you. Behind that, a deep growl that seemed to rattle your very bones.
“Where are you going?”
The question had been mostly rhetorical in a sense, aiming to make you think twice about even moving—you should’ve known better than to move with him buried so deep into you. His instincts would have never let his mate simply wander away after such a session.
Especially not when he still had to be sure that you would be bred filled properly. No. That just wouldn’t do.
Then, suddenly—as if remembering just what was going on and who he was—Atsushi murmured apologetically. His already flushed face grew crimson with shame. “I-I mean…please don’t move. You need to stay right here. Trust me, it’s for both our sakes.” His white lashes fluttered, sunset eyes turning to you; his pupils nearly swallowed the brilliant colors with a deep void of black. You knew exactly what that look meant, damnit it all.
‘ ‘For both our sakes’, my ass’ You thought bitterly, settling back down.
“Just one more..?”
His voice was tender, gaze pleading as his hips shifted just slightly, dick twitching and jolting inside of you. It hadn’t even been five minutes and he was already ready to go again. You’re not sure you could even stay awake for much longer. This was beginning to look like some endless loop with him.
After a moment, you finally relented with a reluctant ‘fine.’ A pleased chuff rumbled out past his nose and into a gentle chirp. His nose pressed against the underside of your jaw with a deep inhale, nudging along the skin with a mix of appreciation and quiet reverence.
“T-Thank you, sweetheart. Thank you so much,” he was barely pulling out halfway before he was whimpering and spearing forward, hands finding purchase right back on your hips again and squeezing. “Y-You’re too kind to me. I promise it’ll be good—I’ll be good. I’ll take good care of you, I promise. I promise, I promise, I promise—“
He was going to be the death of you.
