Work Text:
Isagi was in a relationship with his teaching assistant.
Well, he wasn't just his TA—Bunny was his clanmate. His childhood friend. His fellow rabbit hybrid.
They've known each other forever.
Bunny came from a different rabbit subspecies—taller, broader, with snow-white fur and striking blood-red eyes. He'd belonged to a now-dispersed mountain clan of hybrid rabbits, once proud and private, until something happened and the group fractured. He arrived alone, not a single trace of family left, and found shelter in Isagi's village instead.
At first, the rabbit hybrids were wary. His size, his stare, the scar… it made the smaller clan members uneasy with their different upbringings. But Isagi's parents welcomed him without hesitation. Offering food, bedding, everything a young hybrid needed to feel safe. And Isagi, still small and curious back then, followed their lead, playing with Bunny and helping him get back on his feet.
Trust came quickly after that.
Years passed, and when the time came, they both left the burrowed safety of their clan behind, heading to the city for school to merge with other hybrids and build their own paths.
Now?
They're keeping their relationship lowkey for now. Not exactly a secret, just… private. It's still new, still soft around the edges. But even if no one knows, everyone could probably guess—Isagi and Bunny have lived together since forever.
That's just what rabbits do. You stick close to your person.
But in a world full of hybrids, scent was a big thing. Pheromones, smells. Everyone had their own natural scent, and everyone could smell anything, especially when someone was agitated with emotions and flustered.
And for Isagi? That's always been a bit of a problem.
Apparently, something about him draws attention. Maybe it's his smaller rabbit subspecies, or the way his soap and lotions blend with his natural scent, or maybe predator hybrids were just freaks. Either way, they sniff him out like it's instinct. Even though rabbits don't go into heat, he's heard one too many gross comments like: 'you just smell real sweet, like a mate, y'know?' from wolves, foxes, and the like.
Thankfully, Isagi's gotten good at managing himself. Mostly.
But Bunny hates it. Hates them . He growls whenever someone gets too close. His rounded white tail would thump. His ears flatten. And so he started scenting Isagi on purpose, casual at first, rubbing against his neck, his jawline, then his thighs as their relationship grew further.
And to be fair? It works.
Bunny's scent covers Isagi's completely now. Gone is that light, sweet mix of blueberry and vanilla—now replaced with something colder. Subtle linen, crisp snow, and that unmistakable edge of Bunny.
But more than that... Isagi smells mated .
And that's what really keeps the hybrid predators away. Wolves, foxes, all of them—they wrinkle their noses and keep their distance from the scent. They hate the scent of a prey animal who's already been claimed.
But there was more Bunny could do to keep his scent lasting longer on Isagi.
At first, it wasn't intentional. Bunny was actually a little embarrassed about it.
Isagi had blurted out one day that he had forgotten to clean when they had sex and that he went the whole day with…his seed inside him. But much to his surprise, not a single hybrid so much as looked at him weird that day.
No one approached him. No one flirted. No one sniffed too close.
After that? Well… it kind of became a thing.
Isagi started asking for it before class—
"Just a little, nii-yan, so they back off…"
And Bunny who was a little flustered at first, started obliging.
Then, every morning, he'd check. Make sure Isagi was still full. Still marked. Still his.
And now?
Now it's routine.
Bunny fills Isagi's pussy every day before class—slow, deep, heavy. Leaves him dripping with his cum. And just… goes. Like he's putting on his mate's cologne, but inside him.
…
Isagi swears they're normal!
And this morning?
Same thing.
Bunny wakes Isagi up with lazy grinding under the covers, presses sleepy kisses to the nape of his neck, and slowly pushes his cock inside—fucking him full all over again. Once, then again. Layering new loads over what was left from last night.
By the time Bunny's zipping up his pants and kisses him goodbye before heading out, Isagi's a dazed, trembling mess.
And he's left there. Dripping.
He decides at that exact moment that it's a problem.
He doesn't want to walk into class like that again. Not with the way Bunny's cum leaks and stains his underwear gradually through the day.
So, naturally, he gets an idea.
A stupid idea.
A carrot.
Thick. Firm. Just the shape had him thinking that it could plug him throughout the day.
Bunny won't notice it's missing from their dorm— den's —kitchen. Isagi lubes it up and slides it inside, hoping it'll at least keep the liquid in until the day's over.
But what he doesn't account for?
The shape.
The girth.
The slightly rough texture caught on the walls of his pussy just right and made his hips twitch.
Now that it had settled, and he had adapted with something inside of him, the way the shape slotted just near his sweet spot was a little too much. Never mind the thick girth that was only second to Bunny and had him yearning to be filled out in a different way.
So now here he was, sitting in the back of his last class, after enduring a day's worth of undeniable pleasure. His thighs were pressed tight, furred ears twitching, face pink, trying not to moan every time he shifts.
Because the fat carrot stuffed inside his overstimulated, cum-filled pussy was doing way more than just plugging the leak.
It felt so good.
Too good.
Unable to resist the pleasure, he lets out a soft gasp, then slaps a hand over his mouth as he remembers he was still in his lecture, waiting for the prof to arrive.
"Isagi?"
He jumps. Bachira is looking at him. Then his two other friends, Hiori and Chigiri, sit at their usual seats, slightly worried. Bachira and Chigiri were cat hybrids while Hiori was a sheep hybrid, distinct by the furry cat ears and rounded horns respectively.
"You okay?" Bachira asks in a teasing tone.
Hiori tilts his head, "You look like you're… sweating. And fidgeting."
"...Are you about to diarrhea!?" exclaims Bachira, happily.
At that a few people giggle in the background, as they sit down for their lecture as Bachira laughs loudly.
"I—I'm not—I'm fine! Bachira's just joking!"
Chigiri turns from his desk. "I've been thinking…you smell a lot of Bunny lately? I mean I know you two are roommates but…?"
"I mean, yeah, we're close you know—it's normal for rabbit hybrids!" Isagi lies quickly.
Hiori raises an eyebrow. "...How close?…I'm pretty sure Bunny's just into you."
Isagi goes red.
"I don't…I just—had a weird breakfast, okay?!"
Isagi tries to focus on the board, but the carrot inside him shifts with every little movement, the faintest intake of air. He's full. Too full. It's pushing Bunny's cum deeper, rubbing against that sensitive spot, and he feels another wave of slickness starting to spill around it.
And then it gets worse.
Because the door opens. And Bunny walks in with their professor.
Isagi's head snaps up.
Bunny, his TA for this class, calm, tall, perfect in his button-up shirt, the distinct scar and ruby eyes, glances over the class with disinterest. Until his eyes land on Isagi.
And then he pauses.
His gaze lingers for a second too long. Sharp. Red. Curious. Then he continues walking like nothing happened.
Isagi swears his heart stops . Did he notice? Did he smell something?
The rest of class is a nightmare. Isagi bites his lip as he tries to stay still while his fingers dig into his thighs to focus on anything else. His friends stop asking questions, but he can feel their glances. He doesn't answer anything the professor says. Doesn't even register Bunny discussing their assignments.
When the dismissal bell rings, Isagi's out of his seat instantly .
"Isagi?" Hiori calls, confused.
"Can't talk—gotta go…uhh...diarrhea—!" Isagi blurts, grabbing his bag and bolting out of class.
"I knew it!" he hears Bachira exclaim at the last moment.
He sprints down the hallway, thighs shaking, pussy clenching hard around the stupid carrot with every step. The thing shifts inside him with every stride, heavy, snug in his cunt.
He barely makes it to their den tucked at the edge of their building before slamming the door shut and collapsing onto the floor.
And then—
He tries to move. Just slightly. Just enough to maybe pull the damn thing out.
But the motion drags it along the inside of his walls just so perfectly against his sweet spot, and the panic tips over into full-body pleasure. His back arches. His hips jerk. And with a humiliating, shuddering cry.
He cums.
Hard.
Right there on the floor.
Panting. Shaking. Still fully clothed. Still stuffed.
"…I'm going to die," he mumbles weakly, staring at the ceiling as his pussy flutters around the carrot still snugly in place.
The school halls still carry the usual scent of musk and dirt, but the minute Bunny crosses into the housing wing, something hits him hard.
A scent. Familiar. Sweet. Too sweet.
Isagi.
He stops in his tracks. His nose twitches, ears going sharp, posture tensing. Isagi's scent was strong today—stronger than usual. Despite the usual cover, today it was thick, ripe, with something new lingering beneath it.
He drops his work bag to the side and mutters, "What's going on…"
He finds Isagi right where he always is after class: curled up in their bedding, shirt too big for him—his shirt, to be exact—along with no pants, flushed and twitching.
"Nii-yan! " Isagi squeaks, ears perked up as he sits up quickly. A little too quickly.
Bunny frowns.
His eyes fall straight to Isagi's bare thighs—glistening, parted slightly. There's a glint of moisture there that has nothing to do with sweat.
He stalks forward.
Isagi stiffens. "Wh-What's wrong?"
"Your scent," Bunny says flatly, towering over him. "It's too strong. Who were you with?"
"I—just class, you saw me…" Isagi says fast, panicking. "I wasn't with anyone!"
Bunny raises a brow at the suspicious behaviour, clearly not convinced.
Then he leans down, hand on Isagi's chest, pushing him onto his back.
"You can tell me that," Bunny says, voice low and edged, "but your pussy won't lie."
Isagi gasps. "B-Bun-nii-yan—wait—!"
Just as Bunny pushes his legs apart, something bumps against his wrist and rolls free.
Orange. Thick. Slightly shiny.
"…Is that a carrot? " Bunny blinks.
Isagi goes crimson . "I—! Wait, don't look! It's not what you think—!"
"What the hell were you doing with—?"
"I had to!" Isagi blurts, covering his face with both hands. "I was leaking! I didn't want to embarrass myself during class, so I thought—I thought I could use it as a plug!"
Bunny stares at him in stunned silence.
"And it worked! " Isagi insists, as his ears were perked high in defiance. "At first. But then it felt… too good… and I couldn't get it back out without...making it worse!"
Bunny blinks again. "…So you stuffed yourself with a carrot."
"It was that or cum down my legs in biology!" Isagi groans, defeated as he hears himself say such degenerate things. "I wasn't doing anything with anyone! Don't look at me like that!"
Bunny lets out a long sigh, his long white ears twitching.
"…I'm sorry, Isagi."
Isagi blinks, a little breathless still, head spinning from everything.
"For getting jealous and misunderstanding you," Bunny murmurs, brushing his fingers along Isagi's reddened cheek. "And for… well, walking in on you with a—"
At that, Isagi flushes hard again.
"I forgive you!" he blurts, face burning. "But can we not talk about how you just saw me masturbating with a carrot—?!"
Bunny's eyes flicker—something dark flashing through them. Something hungry.
"…You were serious?"
"Don't ask anymore questions!" Isagi snaps loudly. He fists a hand in Bunny's shirt and tugs him down. "Just— do something , okay? Please…"
Bunny growls low in his throat.
He slides his arms under Isagi's knees, lifting and folding him open without hesitation. Then he lowers himself, eyes locked on the slick between Isagi's glistening thighs.
His nose dips lower, hot breath fanning across flushed skin. The scent of Isagi—sweet, soaked, ruined—is overwhelming.
"Still leaking from this morning," Bunny murmurs.
Isagi bites his lip. " Y-You filled me up…"
"Can I still check?" Bunny murmurs.
Isagi nods quickly, parting his legs further.
Bunny's thick fingers spread him open. Isagi whimpers, fingers gripping the bed sheets.
"Bun-nii-yan—wait—it's embarrassing…"
"I'd happily die in your pussy."
Isagi huffs, trying to kick the other man. " Pervert , just go—!"
Chuckling, he presses his thumb in between Isagi's folds, gliding through the translucent slick, opening him up till the familiar white oozes out. At the sight of his cum, Bunny exhales.
"If someone had touched you, I'd smell it here. Feel it here."
Isagi gasps as Bunny then proceeds to slide in a finger easily, curling the digit just enough to hit a sensitive spot.
"Mngm— ahh …!"
"You're so soft inside," Bunny murmurs, voice thick. "This pussy was made for me, wasn't it?"
Isagi mewls, squirming on his back, trying to grind down on Bunny's hand.
"You get wetter every time I say that," Bunny says with a grin. "You like when I check you?"
"Y-Yes…nii-yan—more, please—don't stop," Isagi whines.
Bunny adds a second finger, stretching him slowly, rhythm steady. The scent in the room gets thicker . Intoxicating.
"You're going back to class tomorrow full of me," Bunny says, pressing deeper. "If anyone looks at you, they'll smell me first."
"I want them to know," Isagi moans. "I want them to know you bred me…"
"You want them jealous?" Bunny's tongue flicks over his clit, slow and taunting. "You wanna walk in dripping so they see what a claimed rabbit looks like?"
"Nii-yan—I'm—" Isagi cries out, legs twitching, back arching.
Bunny doesn't stop, fingers thrusting into the tight, sloppy heat as he sucks onto the reddened bud, until Isagi's coming hard, twitchy, soaking his hand with a fresh gush of slickness.
When he finally pulls back, his lips and fingers are wet.
"…Your carrot could never do that, right?" he teases.
Dazed by his orgasm, Isagi doesn't answer, and with the heated way Bunny was looking at him and the large tent in his pants, his cunt only clenched and ached in need of more.
Bunny shifts above him, eyes dark.
Then, he unbuckles his belt.
"One more fill," he mutters, voice thick. "Just to make sure."
Isagi's breath catches.
"Hold open your legs."
He obeys without hesitation—hands on the backs of his knees, spreading himself wide for Bunny. Slick and leftover cum begins to drip from between his folds in long, opaque strands, soaking his tiny tail also.
The sight makes Bunny's nose twitch as his cock throbs inside his pants.
"I'm going to make sure you're stuffed again," Bunny growls.
He kneels between Isagi's thighs, belt falling loose, pulling his cock free—flushed, veiny, and leaking at the tip. He strokes it once, then lines it up, rubbing the head along the puffy lips of Isagi's twitching entrance.
Isagi shivers, hips jerking up.
"Nii-yan," he moans, his furred ears drooped in desperation. "Hurry, I want it—I want you again…"
Bunny groans. "You're so needy for me. Always this wet for me. Always begging. You know what that makes you?"
Isagi's voice trembles. "Yours…"
"Say it louder."
"Yours, " Isagi cries out, squirming. "I'm yours—I'm your mate !"
That has Bunny growling, he drives in hard , one long, slow push until he bottoms out. Isagi chokes on a moan as he's stretched open again, the thick shaft filling him completely.
"Fuck, you're so wet and perfect…" Bunny grits out, "You're clamping me… Easy, I'm not going anywhere…"
He starts moving, slow and deliberate at first, savouring the way Isagi's walls flutter and squeeze around him, like his body is pulling him deeper on instinct. The heat, the wetness, the sound—it's all too much.
Isagi's arms wrap around his neck. His legs lock tight around Bunny's waist.
"More, nii-yan...ahh … please—harder," he begs. "Breed me again—make me yours again!"
Bunny loses it. He snaps his hips forward, pounding into him with brutal, wet slaps. Each thrust pushes their bed frame hard into the wall, every collision loud and raw. The room fills with sound—slick, fast, filthy.
"You're so good," Bunny pants into his ear. "Such a good mate. All mine."
"Only you," Isagi gasps, "Only Bun-nii-yan…"
Bunny thrusts faster, thicker hips slapping against Isagi's perky ass. His hand slips between them, fingers teasing Isagi's clit with practiced ease.
Isagi is trembling beneath him, nearly boneless as the constant pleasure overwhelms him. "Nii-yan— ahh …it's too much—feels too good… I'm gonna—!"
"Cum for me," Bunny growls. "Cum from my cock."
And Isagi does—body tenses once before shuddering, pussy clenching tight as his orgasm crashes through him like a wave, squirting around Bunny's cock. He cries out breathlessly while he grabs at Bunny's shoulders, trying to anchor himself through the feelings.
"Isagi—"
Bunny fucks him through it, chasing his own high. Thrusting a few more times, before he slams deep, burying himself to the hilt and groaning low as he releases inside, cock throbbing, thick seed spilling rightfully into Isagi's filled cunt.
He stays there for a long moment, not pulling out.
Neither of them speaks—just panting, tangled together, trading slow, heated kisses between shallow breaths.
Bunny's cock remains nestled inside, thick and warm, cradled by the heat he's so thoroughly claimed. Eventually, he pulls back just slightly, lips brushing against the smaller hybrid's cheek in a softer gesture while Isagi softly slides his fingers over Bunny's scar.
"…Still leaking."
Isagi blinks up at him, dazed with pleasure and exhaustion.
"But it'll hold now," Bunny adds, a satisfied smirk on his face. "I bred you good."
"You always do," Isagi breathes, feeling oddly safe in Bunny's arms and larger body.
His body is lax beneath him, ears drooped, and his tiny tail flickering from being pinned down. His pussy is twitching, oversensitive, and full. Bunny finally slowly pulls out, and a thick spill of cum leaks out with a wet drip.
But Bunny's already reaching for the carrot again, eyes sparkling.
"Let’s keep it all in this time, yeah?"
Isagi bites his lower lip, a shiver running down his spine at the sound of it. That low, possessive tone always gets to him.
He swallows, cheeks flushed. "Just… warm it up a little first."
