“...Hiyori-kun.”

“Mm?” Hiyori turns her head with a smile, nose bumping against Nagisa’s jaw.

“...Your heat is soon, isn’t it.”

A small blush covers her face, but she laughs. “Yes, it is! What, were you planning something special?”

“...In a sense.” Nagisa gives a serene smile, arm around her tightening. “...Hiyori-kun, do you have any fantasies?”

“Eh?” This finally manages to catch her off guard, her face showing surprise for just a second before returning to normal. “Well, of course! So you are planning something… Are you just asking if I have them, or are you asking to hear them?”

“You know I’d like to hear them.” Nagisa puts a hand over Hiyori’s. “Give me one of your favorites.”

“My favorites, mm…” Hiyori hums thoughtfully.

Nagisa strokes his thumb over her hand, drawing a purr from the older. She presses her face against his neck, taking a deep breath of his scent.

“...Well, I have one I’ve hoped to try…”

Just a slight, faint smell of roses.

Nagisa smells it from the kitchen, and it’s enough to make him drop the dishes he’s washing.

As they clatter against the sink, he turns his head slowly, looking at the door to their enclosed loft. Hiyori had been quick to claim it as her nest, and Nagisa had no objections. It’s a comfortable place to pacify her during her heats.

This time, though… The smell coming from the room, though it’s no stronger than ever…

Something immediately stirs in him.

He can feel himself flush, his heart beats faster. He grips the counter with his hands and sighs.

It’s begun.

He makes a mental note of how strong the scent is. It smells desperate, but not unimaginably so.

So he dries his hands. Moves to the living room. Grabs a book, and lies on the sofa.

…He’s hard.

…It’s going to be a long wait.

The smell is absolutely getting to Nagisa now.

It’s grown from roses, to sugary pears, to an all-encompassing honey-musk.

Just moving his leg, he shivers.

Everything feels hot. He’s panting, despite being sedentary. He’s flushed, sweaty, and there’s a burning ache in his abdomen and groin.

It’s… probably time.

Shakily, he closes his book, the words of which had gone in one eye and out the other, for… he doesn’t know how many hours.

Only the best for his Hiyori-kun.

It’s hard to walk with his pants fitting as they do. He sheds them. And makes his way across the room, up the stairs, to the entrance to the loft.

His instinct is to knock. But…

The door creaks as he opens it with little warning.

The smell, proverbially, knocks him on his ass.

It saturates the pillow-strewn room, like the most pleasurable of toxic fumes. It would be suffocating, were he not in the later beginnings of rut. And it only gets stronger as he opens the door further.

And inside, there she is.

The source of the smell is curled around a pillow, aching hips grinding endlessly. She’s sweating, flushed all over. She’s shaking, whining, crying.

She’s ethereal.

Hiyori looks up.

“N—Nagis—a—” she hiccups out.

The sound goes directly to Nagisa’s cock. He gulps.

“Nagi—sa—..?”

Tears pricking at the corners of her eyes, her breathing has become ever more shallow. Hackles raised, all hairs standing on end. She adjusts, sitting reclined and foggily attentive, in and out of clarity.

“...Hiyori.” Nagisa steps inside fully. A violent shiver goes through Hiyori’s body.

He closes the door.

Instinctively, Hiyori backs up just a bit, but Nagisa closes the distance quickly. She gasps, and he’s on top of her.

“You— mmh—! ”

Hiyori is quickly silenced with a kiss, moaning helplessly as she grabs at Nagisa’s shoulders. He breaks away and is immediately at her neck, biting at her, not hard enough yet to mark.

“...Flip over.”

Hiyori’s eyes go wide, panting heavily, and she doesn’t obey.

“... Hiyori .” Nagisa’s voice contains a thunder Hiyori isn’t used to, drawing a little ‘eep!’ from her throat. “ It was not a request .”

Of course it’s a request. He would do absolutely anything for Hiyori.

But there are wonders to be found in the world of acting.

He grabs her hips. She jolts, and suddenly she’s on her knees, chest to the floor, whimpering. “N—Nagisa, Nagisa—!!”

“What? Say what it is you want to say,” he growls deeply, nose by her neck’s scent glands as he drowns in that intoxicating aroma. “You want this. I know you do. Your body yearns. You wouldn’t care no matter what I do to you.”

Hiyori opens her mouth to respond, until teeth are on her neck, and she’s moaning outwardly, almost a shout, shivering so heavily Nagisa almost worries. “A—AAaahhh, wait—Wait—”

…No safeword comes from her mouth. Nagisa internally sighs relief.

“You’re made for this .” To punctuate the statement, Nagisa shoves two fingers into her cunt without warning.

A half-second shriek escapes Hiyori’s throat.

Her hips strain away from the overstimulation, but Nagisa’s other hand holds them steady. “ You can take it. I know you can .”

After a few seconds of wriggling and moaning, her hips begin to cant back into the touch, and she muffles a long wail into the pillows below her—until a strong hand is in her hair, tugging her head back up.

“ Don’t hide yourself from me ,” Nagisa snarls.

“I—I won’t… I won’t…!” Hiyori pleads. “A—Aahhhhh hhh , oh God, oh God, please—”

Hiyori yelps as the fingers inside her pound faster, and the hand in her hair grips harder.

Nagisa bites her neck a bit harder, before drawing back and giving almost apologetic, kittenish licks—he can’t help breaking character just a bit, but quickly snaps back into it. “You think you have a say in this? You’re an omega. You’re in heat. I’m an alpha. I’m in rut.” He takes a deep breath, before sighing his preparation. “...You’re made to be used. You’re made to be my bitch .”

“N—” Hiyori is cut off by a guttural noise as a third finger invades.

It’s unclear if it was intended to be Nagisa’s name, or a protest.

…But it’s not the safeword.

So he continues.

He removes his fingers, each completely soaked, and pulls down his underwear—he has to let go of Hiyori’s hair to do so, and her head falls to the blanket-covered floor, panting and giving high-pitched groans. “N—Nagi—sa…”

“This is what you’re intended for,” Nagisa whispers, stroking his own cock languidly. “You’re a common whore. Mine to violate.”

He gives Hiyori a moment to process the word, assessing her reaction.

Her back arches . She keens loudly, gripping the sheets and pillows. Wiggles her ass invitingly.

…So he is doing something right.

So he plunges into her without remorse.

She’s wet enough that he can get almost all the way inside in one go, and Hiyori shrieks. Nagisa’s hand grips her hair once again, this time pressing the side of her head to the ground as he finds a comfortable spot, breathing heavily.

“N–aaaaaaahhhhhh hhhh — gisa —” Tears flow freely down Hiyori’s face now. Nagisa leans forward and kisses the corner of her eye.

“Shhh, little one. You don’t need to think. Let go.” He gives an experimental piston of his hips. She yelps loudly .

…Just in case, he taps her shoulder twice. When she looks at him, he brings three fingers to his lips briefly.

Hazy as her eyes are, shaking and panting, she does the same.

The final confirmation Nagisa needs.

Pressing her head down with his full weight, he begins fucking into her without mercy, sheathing himself all the way down to the knot with every thrust, and Hiyori is seeing stars . She wails with a ragged edge, noises punctuated by minute stops and starts with each thrust.

“ Good girl ,” Nagisa growls.

Hiyori would tighten, but she’s stretched to her absolute limit.

“Brainless slut,” he continues. “All you want is cock. There’s nothing else on your mind, ever. You’re always thinking about when you can next get fucked, bent over and railed.”

“ Y—Yes ,” Hiyori breathes. “A— AAh!!!”

She gives a noise of overstimulated shock as Nagisa picks up the pace, sniffing and licking her neck. Nothing he does is without guilt, of course.

But he really would stop at nothing to make Hiyori happy.

So he balances out his filthy words with sweet actions, kissing the few bite marks that currently reside at the side of her nape.

The pleasure is becoming a lot for him—he’d ignored it somewhat in his attempts to please Hiyori, but his cock throbs , and he can’t ignore it anymore.

“Y—You feel amazing,” Nagisa breathes, just loud enough for Hiyori to hear over her own noises. “M—Maybe I’ll keep you as my personal cocksleeve… It’d be the best use of your body.”

He speeds up, and Hiyori’s noises take a turn. They’re almost inhuman, perhaps a bit far from even being attractive, but to Nagisa, they’re everything .

“N—Nuuhhhh—Nah—Gi–Sa—” Hiyori stutters out his name like it’s the only word she knows. “ HaaaAAhh— ”

Nagisa gives a deep growl, panting and resting his forehead against the nape of Hiyori’s neck. Both hands have moved to her hips, locking them in place while he takes what he wants from her. She’s unable to squirm away, no respite from his knot. She’s slick and when she’s stretched around him she feels so tight and he feels that feeling building in his abdomen, itching and pleasurable. And he can feel her in the same state, walls quivering and pulsing.

He gives her earlobe a probably-too-sharp bite, and she makes another delicious noise. “You’re close. You love this. What a pretty little cumdump…” She whines high and loud at the name, not bothering to quiet herself in the slightest. “I’m going to breed you. Don’t you want my pups? I’m going to fuck you over and over until you take, and everyone will know you’re mine .”

“ Nagisa!! ” she shrieks, whole body shaking violently. She can’t find the words, but she’s so, so close, and every word Nagisa says pushes her further. And Nagisa doesn’t miss this.

He changes his thrusts to be shorter, but deep .

“That’s all you are… A breed mare. Nothing more.”

Hiyori convulses, and her body squirms, locking up in little intervals as she screams , grinding back against Nagisa’s cock as hard as possible as she releases all over his lap. The trembles she has make it look like she might even pass out… But she wails and wails and wails , sobbing and babbling incoherent sentiments and pleas. At least from Nagisa’s perspective… she’s having the most unbelievably intense orgasm he’s ever seen from her, even in any heat. He can’t help but growl as he grabs at her plush rump, pounding into her with fervor.

“T—There you go,” he coos.

And the moment she starts to calm, he gives one last deep thrust in and out and bites down hard on her neck.

The mating bite, and the sudden fullness of all of Nagisa spilling inside her, more than she ever thought she could handle… Hiyori’s world goes blank. Her mouth is open in a silent scream, with an occasional ragged gasp, as Nagisa groans and whispers endearments as he rides out his own peak. Hiyori can’t hear him, can’t see anything, can only feel the burning feeling through her core, spreading her whole body. Her second orgasm hits so much harder than the first, she genuinely thinks she might drop dead right there. Nagisa, in his feverish peak, can sense every little thought of Hiyori’s, or lack thereof. They’re connected in a way that no one else is. That they aren’t with anyone else. That they haven’t been with each other before.

Nagisa cums, and cums, and cums , shocks going through his body as he loudly and almost tearfully groans, until he’s emptied himself completely inside her. He feels the heaviness of his knot stretching her, and fights collapse. Notices his teeth still buried beside her neck, and releases her. Breathes hard as the world spins around him.

“N…agisa…”

The small utterance of his name wakes Nagisa, and without bothering to ask, he shifts their position so that they are both lying down, Nagisa spooning Hiyori. She gives a shaking, purring sigh.

“...Hiyori,” Nagisa whispers. He peppers kisses on her neck, lapping apologetically at the deep mating bite. “...My sun…”

“H…haha…” Hiyori breathes out a laugh, throat raw from screams. “N—Nagisa is such a good actor…”

Nagisa smiles widely, taking the hint that the scene is over. “...I could only do what I did because you’re so irresistible.”

“Ha! True…” Hiyori closes her eyes and shimmies back closer to Nagisa, the two of them locked together by Nagisa’s enormous knot. “Mm… This might be the only clear-headed moment I get for a while, so I want to say… Thank you.”

“I want to make you happy,” Nagisa replies simply, kissing the shell of her ear. “I’ll do anything for that. Whatever you ask of me.”

“Hehe…” Hiyori relaxes more, bottom half still a bit twitchy. “Then… will you make love to me for the rest of my heat? I do adore my power eclipsed… but I want you now.”

Ah, there’s the word. Nagisa’s grin grows wider—he adores when she trusts him enough to safeword. Especially in such a floaty, wonderful context.

“Of course,” he purrs. “Anything for you.”
