He glanced over his shoulder at me with his exposed eye, crinkled up in what was probably a wide smile. 

"I can't do that, sensei. We need to make it back to Konoha by nightfall. You can't walk, let alone run. I realize you must feel put off by this, but it's necessary, so please bear with it for just a while."

I swallowed thickly and held his shoulders tighter as he jumped from branch to branch with incredible ease, despite my weight on his back. The movement of his body, those muscles, every shift and flex of them underneath me had my breath coming out in pants. He has no idea what I'm feeling right now, and if he doesn't put me down soon, he's going to get quite the surprise. I shifted my waist as far away from him as I could, but my problem is still there, and it's getting bigger. And gods, but he smells so good.

A dull heat bloomed from a single thread in my neck, moving down, lower and lower.

I shivered.

My growing length twitched. 

"No. You don't understand... put me down. Now!" 

I slammed forward into his back as he stopped instantly without warning. And then I was fully pressed against him, rubbing. My mouth opened in a moan before I could do anything to stop it. A moment later my stomach lurched as he dropped to the forest floor. 

It didn't matter though, I was too busy grinding into his back. Over and over. The heat coursing through my veins spiked. It felt as if it was taking over. 

Something was very, very wrong. 

"Kakashi, Kakashi.... I can't. Something's wrong with me. I need... I need..." You. I choked the last word back, but only barely. 

I couldn't stop moving against him, grinding into him. An intense hunger I've never felt before was overtaking my senses and I was clawing at his vest desperately. 

Why does he smell so good? 

Why does his body feel like bliss?

Why can't I stop?

I rocked against him forcefully, just as he was bending down to his knees, to set me down. And suddenly I was on my knees, and he was bent over before me. He was on his knees too, one hand flat against the ground, the other still hooked around my thigh, presumably to keep me steady. So very kind. My hands moved on their own. His hips were under my palms and I was rutting against him, into him. Into the space between the tight round globes of his ass. So good, but not enough. I need in. 

I need to be inside. 

I can't breathe, I feel like I'm choking. The heat is smothering me. I can't stop myself. I can't control my hands, my body. I can hear myself panting, moaning and pleading. 

I'm begging him now. 

"Please. Let me. I need to... I can't stop. Please, please, please..."

His hand released my thigh carefully, and withdrew ever so slowly. He drew it under him, to join the other one on the ground beneath him, and then he did something I never imagined would turn my world on its head. 

He leaned down, still slowly, laying his face into his arms on the earth beneath him. His ass stayed raised, and I let loose a loud keening moan. My mouth watered. Such a submissive display. So perfect. Head down, back curled invitingly, ass up.

Waiting to be mounted... waiting for me. 

I licked my lips and ripped his pants and underwear down, gasping as his beautiful backside came into my view. My hands were off of him only long enough to push my own annoying garments down and away... But the second his alabaster skin came back into my line of sight, everything else was secondary. Nothing else mattered. I spread the flesh of his glutes wide and shuffled backwards slightly, so I could lean down and taste him. Because I needed to, more than anything. I licked the ring at the center and groaned, fascinated at the way it twitched. I need him. I need to be inside. He needs to take me in. I need him. 

I dove in again, licking and swirling with vigor, stabbing my tongue into the tight pink ring.

Yes. 

This. 

This is what I need. 

I thrust my tongue in again and again, until suddenly, the muscles softened, relaxed, and pale hips twitched towards me. 

Yes. 

Mine. 

This is mine. 

Kakashi is mine. 

Pulling back a bit, I sucked a finger into my mouth, laving it generously, before bringing it to his now soft hole. So pretty. 

It slid in easily. 

"Fuck. Yes....  be mine... So good. You're so good. My mate. Be good for me, okay? Yeah... Just let me in. Let me in... I need you."

The words are pouring out of my mouth now. I'm not even sure of everything I'm saying. He's so hot inside. So hot, so tight. Ready for more. I pulled my hand back, licked another two fingers and slid all three in. His muscles tensed again, so I used my free hand to rub his thighs, his back, anywhere I could reach. I wanted to soothe him. 

It would be alright though. I knew my mate would feel better soon. I'll definitely make him feel good. 

Wait...

My mate?

What the fuck?

His body shuddered, and tensed again... But I simply kept caressing him, and leaned forward to swirl my tongue around my fingers, knowing he'd adjust soon enough.

He's not wet enough, though.

Don't want to hurt him. 

Need him to want it. 

Need to be good for him.

The sound of a zipper startled me, and then a tube was being pressed into the hand I had on his back. 

I sat back to curiously examine it. Some sort of liquid. 

Oh. 

I growled posessively and ripped the cap off with my teeth, emptying half of the contents into the fingers I still had moving into and out of his body. 

So wet. 

So much better. 

Such an intelligent mate.

So good. 

Mine.

He tensed again, but this time it didn't seem to be in pain. He let out a sharp breath and rocked back, ever so slightly, moving my fingers down a little... and then he shuddered just the tiniest bit. I moved my fingers that way once again, and again he shuddered. 

But he made no noise. 

Did he not want me to know what pleases him?

Was he too shy to whine for me?

That would not do. 

I curled my fingers slightly inside him, and shoved them forward confidently, deeply. A grunt, and a shudder. Yes. He likes it there. I attacked that spot ruthlessly, inwardly pleased at the knowledge that he was finally feeling pleasure. The heat in my veins expanded again, and again I couldn't breathe. 

I emptied the rest of the tube onto my cock, and hissed as the cold liquid came in contact. Thick with blood, and heavy, it was almost too painful to wait. But his pleasure is more important than mine. Had to make sure first. Had to do it right. The tube was gone, tossed over my shoulder a moment later, and I was slicking myself up, thrusting into my own palm. My mate was going to feel so much better than that, though. Licking my lips, I watched as his hole twitched around my fingers, sucking them in. So pretty. But it was enough. It's time. I pulled them out slowly and lined up with his hips. 

And then I pushed forward. 

I wasn't prepared for the glorious agony of his body sealing around my pulsing cock. My whole body tingled and throbbed. Slowly, oh so slowly, I sank into him. And when I was finally, finally fully sheathed within his soothing warmth, I roared in pleasure. My hands caressed him gently as I kept my hips still, waiting for him to soften for me, to open completely. I need this to be good for him. To show him he's loved. To show him I'm a good mate, too. I need him to want it. 

And when he finally relaxed once more, the foggy haze and the heat lifted slightly... I could think again, but still my hands moved to his hips, as I drew my own back and thrust in, aiming for that spot that had made him tense earlier.

My hands... They weren't pulling away from him like I wanted them to. 

I can't stop. 

I'm trying, but my limbs aren't listening. 

This is wrong. 

So very wrong. 

Why can't I stop?

What the fuck is happening?

"I'm sorry. I can't sto-ooh... I don't know what's... Ahhhh... Ahhnn! I need you... I'm so sorry! Please?!"

Tears of fear and frustration began streaking down my face, my vision blurred, but still I couldn't stop. So I kept apologizing, begging him, telling him that I can't. 

I need to come. 

I need to stop, but my body won't listen. And I can't come. I can't stop until I, but it's not, not enough...

"Iruka... it's a-alright. It's alright. Just, unnh, just breathe. I under-... I get it. You, you can't stop. It's okay, y-you don't have to..."

I swallowed thickly, blinking back the wetness, trying to catch his exposed eye as he gazed over his shoulder at me, even as my hips worked him open, pushed in deeper. So good... And then, he was shifting, leaning up onto his hands, on all fours, rocking back into me... responding to me. 

And then he moaned. 

Fuck yes. 

I need that. 

That's what's missing. 

I slammed into him, adjusting the angle again, looking for that sound again. Needing to hear it, like it was my only saving grace. 

"I'm sorry..."

I said it again, because my voice was the only thing I seemed to be able to control. And I was sorry, but it still felt so good, and I was moaning again. But this time his moans and whines joined mine, intertwined with them, and I thrilled at the way we sounded together. 

"It's o-oh-okay... I won't break. C-come on, Iru-uh-ka... take me. Do it... Make mhmm-me feel you... fuck me, ha-harder... I want it... Make me, mnnn.... make me take it..."

My blood was on fire. 

"Yes."

I roared again and leaned over him, one hand hooking onto his shoulder, the other firmly planted on his hip, and when I pushed in the whole world shrank down to Kakashi. To his body, his breath, his movements, his skin. His body, the place where we were connected, started giving over to me, taking me in, and trying to keep me there. I felt him pulse and flex around my thickness, and he cried out, pushing back against me, moving with me. 

"Come ooh o-on, I-Iruka. Ye-yeah... so good. S-strong mmate... Want you, nnnm... need it... want y-your pups..."

I didn't have any idea how he knew what to say right then to get me to lose it, to lose myself completely in him. All I knew were his noises and pants and heavy breaths, the sound of our skin colliding, the amazing way he smelled, and that he was getting close. I fucked him harder, faster, reached the hand on his hip down to grasp his leaking length, and fucked him down into my waiting palm. So good. Soft, yielding, wet, yet hard and firm.

A fine mate.

My lips were drawn to the back of his neck, my tongue lapping at the small bit of it that was exposed, he shivered and pushed back onto me, then shoved into my hand and back onto my cock again. Our rhythm was frantic now, barely held stable, but I kept licking that small bit of flesh ever so carefully, let my teeth graze it gently... and I'm whining, begging, but I don't really understand what for, or why.

Everything was perfect, I just need a little bit more. It's almost enough. 

"D-do it... Fu-uuuh-ck... M-mark me. Y-yours... Make, nnn make me yours..."

Mine. 

My mate. 

He wants me. 

He chose me. 

Yes.

I reared back, growling in pleasure, giving him everything I had, my hand, my cock, my voice, my breath, my pleasure... everything. 

And right as he began to pulse in my hand, and his seed began to spill, I bent down to his raised neck and sunk my teeth into his soft flesh until I tasted blood. He loosed a keening howl, and I was lost.

Flashes of light overtook my vision, all the haze and the heat poured out of my body, flowed out, and crashed into him. I trembled and whined as I lapped at his neck, cleaning him, nuzzling him, and milked our pleasure for as long as I could. 

When the orgasm finally subsided, and my senses returned, my limbs finally started to obey me. I tried to move away slowly,  afraid to even speak... but a hand cupping the back of my neck held me gently in place. 

"Not, fuck, not yet. Just give me a moment, sensei. I, I need to catch my breath. Gods above..." He trailed off, still panting, and I felt him trembling slightly. 

Pain stabbed through my heart, and my stomach rolled. I hurt him... shit, I can't believe I hurt him.

"I'm sorry... so sorry. Are you alright? I don't understand... I don't know why I couldn't stop, why my body wouldn't listen... I'm so very sorry."

The thumb on the hand still grasping my neck began to move in small soothing circles, and he was hushing me softly. 

"Shh, sensei. It's fine. I wanted it, didn't I? Didn't you hear me ask for it? Demand it? It's alright. It's not your fault, and I'm more than okay. Don't worry... everything is fine."

But how can everything be fine?

I don't know what happened... well I know what happened, but not why. And I'm still buried inside of him, slowly softening, and his come is dripping from my right hand. His touch is soft, soothing, his fingers spreading into the loose hairs at the back of my neck. 

"How is this not my fault? What the fuck happened?"

He hissed out a breath as I finally grew too soft and slipped out of him. He shivered and slowly began to shift under me, he rolled to the left and fell with his back to the ground, still panting lightly. He stretched his back and lifted his hips, pulling his pants and underwear back up. I rose up onto my knees and did the same, and wiped my hand on my covered thigh, before dropping my hands back to my sides, at a total loss. A pale gloved hand lifted up toward me, and beckoned me to him. 

I went, falling against him, and into his comforting embrace. 

"It's my fault. I took us this way because it was faster... I knew it was the wrong season to travel through this area, but I figured it'd be alright. I honestly didn't think you'd be affected, and I've learned how to avoid getting caught in it."

I frowned and buried my bright red face into his vest, curling an arm around him. 

He held me a little bit tighter and hushed me once again. 

"It's dog demon mating season. If they're too deep in rut, and they're strong enough, they can possess someone and take the edge off by simulating mating that way. It helps them calm down so that they're free to continue their own search." I buried deeper into his vest, feeling sick. The explanation wasn't helping at all.

He just chuckled, and warm fingers slid into my ponytail. 

"You know what else, Iruka? They don't just make a person mate with anyone... it only works if the person their host desires is nearby..." My face and neck were scalding, I was so embarrassed. I groaned into his chest and he hummed lazily. 

"It's alright... I told you, didn't I? I wanted it..."

I reared up and gazed down at him in shame and hot embarrassment, finally meeting his singular relaxed gaze. 

"I fucking bit you, Kakashi! I took you, forced myself on you, into you, and your come is drying on my pants! I didn't even... I didn't even get to take you to dinner properly, or to just tell you how I've been-... I just attacked you like, like some sort of beast! How is any of that okay?!"

He laughed then, a light, breathy sound... and it was so very lovely. Strong arms pulled me back down against him and kissed my temple through his mask. 

"You didn't just take me like a beast. You waited for my signals. You didn't do anything until I gave you the go ahead. I bent for you first, presented myself submissively, and then you rightfully proceeded. You prepared me very, very carefully, and waited until I pushed back to go any further, every time. You didn't even want me until you were sure I was feeling it too. And you honestly weren't going to bite me, either. You asked by licking. If I'd dropped my neck down and away, you would've just kept licking instead. I raised my neck and told you to do it. Really, sensei... You asked for everything, every step of the way. It just wasn't in a way that a human might ask."

I let out a frustrated puff of breath. 

"Why did you let me, then? Why allow any of it?"

He laughed again, his chest rumbling pleasantly beneath me. Big warm hands pulled me tightly against his side, hugging me close. 

"I've already told you several times, I wanted it. I still want it. I want everything you're willing to give me. Have for a while now. For such a fine sensei, you can be a bit slow on the uptake... You need to get a clue."

I blinked in shock but he just slipped a hand up under my shirt and vest, resting his fingers onto the skin of my hip. 

"Hey Kakashi?"

A beat and then he shifted to try and catch my eye with his. 

"Yes?"

I smiled as my cheeks flamed once again.

"Can I take you out sometime? For dinner?"

He laughed again, sounding amused and relaxed and perhaps a little tired. 

"I'd like that, sensei. Very much."

All too soon he was shifting and then pulling away to stand. 

He turned before me and crouched down, silently asking me to climb onto his back once more. 

"We're losing daylight and we need to get back so we can get that sprain treated. We have to move."

I obeyed, and crawled back into place... mere moments later, we were off and running once again. 

Hours afterwards, just as the sun began to set in vivid orange and pinks... the village gates came into view. I caught sight of the mark on the back of his neck, and it called me forward. I let my nose drag delicately along the skin just beside it and took a deep breath, pulling his scent into my lungs once more. My own neck felt weirdly empty. 

"Hey, Kakashi... next time, how about you be the dog demon?"

His steps suddenly faltered, and I was jarred slightly, but he corrected himself in an instant. That settled, he slowed his stride so that he could look at me over his shoulder. I locked my eyes onto his, and very deliberately leaned forward to lick along my own teeth marks that had been left buried in his skin.

"I want to be yours, too..."

We came to a sudden stop, and I registered that though he'd not been breathing heavily at all during this last leg of the run, not since back in the forest... He was certainly panting now.

His pupil dilated as we watched each other, and my heart thumped heavily against my ribs. A moment later, the hands he'd had curled around my thighs to support me squeezed just once, suggestively. 

"Well, it is mating season, after all."

I didn't stop laughing until we crossed the threshold of the gates and walked into the village.
