Summary

Truly, he doesn’t mind being stolen and hidden away. It’s flattering to have Katsuki fully invest in his instincts like this,
proving that their species difference is only a brief social impediment instead of any real barrier.

He just wishes Katsuki would stop p-pissing on him!

Izuku flexes his toes in the spring, grimacing at the state of his fur. There’s no soft, scented
soaps for him to use in this cave, nor fur-comb or fine-woven towel to dry him after his bath.
All that is available is a mercifully warm natural spring and a hungry, panting mate
somewhere nearby, waiting to pounce the instant Izuku gives him the chance.

He anticipated his first true mating with Katsuki would be a touch wilder than their usual
activities, but the reality is unbelievable. He’s lucky Katsuki got hungry and decided to go
hunt while Izuku was incapacitated from the brutal (incredible) knottings. He’ll probably be
punished for leaving the nest, especially for daring to wash Katsuki’s scent and “claims”
away, but good gods, he cannot spend another minute reeking like he does.

Izuku’s nose wrinkles. He refuses to acknowledge the twitch and ache between his legs, that
he actually likes smelling like Katsuki’s… well. There are natural, profound differences
between rabbit and wolf-folk, but pissing on one’s mate mid-fuck should be discussed before
engaging in the act. Katsuki—deep in his rut and impossible to deter—apparently didn’t find
it prudent to warn his beloved mate what all might occur in their marriage bed.

Not that this cave is their actual bed, since Katsuki grew feral and possessive and carted
Izuku off through the woods at the first stirrings of rut. The clan was understanding, some
even waved and called encouragement as they loped away through the trees. Well, Katsuki
loped—Izuku clung to his mate’s back, doing his best not to be sick at the hard, muscular
shoulder slamming into his belly with every stride.

Izuku sighs, pushing himself off the rim of the pool and into the water proper. Truly, he
doesn’t mind being stolen and hidden away. It’s flattering to have Katsuki fully invest in his
instincts like this, proving that their species difference is only a brief social impediment
instead of any real barrier. He just wishes Katsuki would stop p-pissing on him!

At least he hasn’t pissed inside Izuku—though as soon as the thought appears he loses his
footing in the pool and comes spluttering back to the surface, shivering at the mental image.
His big, burly mate with his narrow waist and long, terrifying claws, cock plunged in deep,
knot swelling—and the hot splash of piss and cum deep inside, stirring his womb with filth
and spill.

Fuck. It should disgust him, but instead Izuku braces a hand against the rocky edge and
furiously rubs the pads of his fingers on his swollen, aching clit. There’s a fang-mark through
its center, another surprise that Izuku initially squealed at and scrambled to escape but wound
up spread wide and begging for more. For all his complaints and denials, he hasn’t done
anything to prove he truly doesn’t wish to engage in all these wolf customs.

Izuku flushes as heat spreads through him; Kacchan isn’t the only one whose instincts are
coming to the surface now. He thought it might take another few days for him to fall into
heat, but that was an estimate made before he realized Katsuki planned to have him on his
cock almost every hour of the day.

A bit of slick and cum eases out of his cunt, pooling between Izuku’s lower lips before
dripping into the spring. Izuku rubs himself mindlessly, rocking his hips to ride the length of
his fingers. It’s nice, it’s something, rubbing his clitoris after days of being forbidden to touch
himself, but it’s not… ugh! Izuku growls and pinches his clit hard, digging his nails into the
glans until a yelp of pain and pleasure pours from his chest. Ah, there—he needed it to hurt,
needed it to feel like what Kacchan does to him. His teeth, his claws, his cock…

“Nnn… fuck,” Izuku groans, pulling the tip of his clit between his fingers, stroking it like a
tiny cock. He bites his lips as Kacchan’s teasing floats into his mind, degradation aimed at his
pathetic little nub, the useless button Katsuki insisted he saw no reason to play with or even
acknowledge. He does, he plays with Izuku there all the time, but sex-games are different.
Kacchan in rut, Kacchan as Izuku’s mate, is different.

He hasn’t been allowed to cum without Kacchan inside of him since they mated. He hasn’t
been allowed to touch his clit, to rub anything but his swollen nipples or the cum-filled curve
of his belly with Kacchan stirring him inside. He has been allowed, encouraged, to get
Kacchan to do those things, however. Kacchan has sucked, bitten, stroked, pinched, flicked,
and rubbed Izuku’s clit any way he likes when Izuku asks. He particularly likes r-riding his
mate’s face—though the last time he did that Kacchan had bitten his clit, abruptly ending that
experience. Even if he did cum from the pain and by instinctual pleasure of being so
thoroughly owned and dominated.
Izuku fingers the little holes in the shaft and glans of his clit, gnawing his lips at the sting of
hot water on the healing wounds. The holes go right through his flesh, tiny, near-invisible
little threads of silk carefully tied through them to keep the channels open. Kacchan promised
he’d put jewels on Izuku’s sex after their mating rite was finished. That he’d lace rubies and
emeralds through Izuku’s lips, above and around and inside his clit, adorning his mate how
he pleased. He even had a long, thin gem he planned to fit in the mouth of Izuku’s smallest
hole, to keep him full and aching whenever Katsuki decided his mate was forbidden from
emptying his bladder save for squirting during sex.

Izuku groans, hips jerking at the thought. Kacchan has played with him down there before,
once, and very carefully. He used a slender, smooth rod of gold with plenty of oil, holding a
mirror for Izuku to watch as it slid slowly, impossibly, into his urethra. Kacchan had fucked
him there, thrusting the little rod in and out until Izuku came, dripping around the sound,
begging to be allowed to empty himself. Kacchan had fucked him truly then, waiting until
Izuku was spasming on his knot to yank the rod free, a feral grin on his face as Izuku emptied
himself with a long, glistening gush.

Embarrassing… really, Kacchan’s interest in piss should have been obvious from that! But
Izuku assumed it was a single situation, not an entire aspect of his wolf-mate’s sexuality.

Izuku grumbles under his breath, avoiding his shifting reflection in the spring’s surface as he
presses the tip of his smallest finger to the mouth of his urethra. It feels hot and ticklish, a
strange sensation that he now understands as arousal, as interest. He used to think it just
meant he needed to go… but Kacchan has made everything sexual. He’s lucky Izuku loves
him so much, to be playing with his piss-hole and dreaming of being pierced and displayed
like a wanton, dripping beast!

A low growl echoes through the cave, immediately bringing Izuku’s explorations to an end.
Only one wolf would dare enter this place now; Kacchan has returned from his hunt… and
Izuku isn’t where he left him, spread and ready for mounting.

“Dekuuu,” a dark, hungry voice warbles through the torch-lit gloom. Izuku hunkers down in
the spring, feeling somewhat defiant after getting to play with himself—and get clean. Thus
far, Kacchan has had the upper hand in their interactions (and their intercourse). But now that
he’s so far gone into his wolf, he has a distinct distaste for baths.
It’s a little funny watching him storm into the grotto after a few minutes’ silence, claws
flexing at his sides, cock straining between his hips and his eyes practically glowing with
furious lust. Izuku hides a smile, watching Kacchan’s face puff with possessive anger out of
the corner of his eye.

“Come out,” Kacchan snarls when Izuku isn’t immediately forthcoming, crawling out onto
the stone to let himself be taken.

Izuku bends his knees further, sinking into the water until only his eyes show above the
surface. The heat feels amazing, easing aches and pains—and ringing a thorough reminder of
his own growing cycle. It makes sense, with a mate in rut doing their best to fuck and breed,
to reciprocate with a cycle of his own. However, if Kacchan was hoping that Izuku is the type
of omega that simply rolls over and whines for a knot in heat, he might be disappointed.
Izuku enjoys submissiveness, being dominated, being claimed. Sure, he eventually turns over
and pleads like any other person, but Izuku likes making his partner work for such
acceptance.

Kacchan has won him many times over in the past; it’s only fair to insist his mate prove he
can still command such submission now. Even though it’s probably suicidal to tempt and
deny Kacchan at this point, Izuku would be disappointed if he didn’t get chased at least once.

He pushes himself backward, tip-toeing across the smooth rock floor of the spring, drawing
further away from Kacchan. His angry mate seems to swell up, fur bristling, teeth bared by
peeled-back lips. A terrifying sight for anyone with prey in their blood, like Izuku. And it
does scare him but at this point Kacchan has skewed his “fear” sense so far into arousal all
the aggressive display does is make him even more hungry for sex.

“Out,” Kacchan rasps, bowing forward with an inhuman noise of pain and hunger. His body
shifts further, the bones of his face jutting forward into a true muzzle as his wolf swims to the
surface.

Rut-rage, Izuku knows, is a deadly state. He needs to move carefully here, minding the
tenuous gap between tease and torment—and the corresponding punishments earned for such
behaviours. To ease Kacchan’s temper, Izuku pulls himself slightly up against the rear edge
of the hot spring, bracing his paws on helpful ledges just beneath the water. This part of the
spring is cut off from the sides, requiring a swim to reach it. it’s the perfect place to force
Kacchan to come to him, to show him what awaits just out of reach.
Izuku cups himself, teasing a nipple with his thumb while his other hand dips between his
legs, spreading his swollen lips to show Kacchan the knot-gaped hole inside. Immediately,
Kacchan’s growl turns to a long, plaintive whine. The wolf-shape shivers, fur receding and
swelling as Kacchan’s body fights between states. Fury or fucking? Evidenced by the hard,
angrily red cock and the half-human hand wrapping around it to stave off orgasm, Kacchan
has decided fucking is a far better use of his energy.

Kacchan inhales raggedly, fists clenching before he crouches and shoves himself off the edge
of the pool and into the water. A visible shudder runs over him—Izuku stifles a laugh at
Kacchan’s deadly glare—before he straightens and begins wading through the spring. His
long cloak trails across the surface behind him, the red fabric turning almost black as it soaks
through.

Izuku licks his lips as Kacchan prowls closer, the heavy lupine brow lowered in
determination over his gleaming red eyes. A gentle tinkle of bead and bone draws his gaze to
Kacchan’s chest, another place he enjoys attending to both in and out of sex. His mate is
wonderfully strong, a prime specimen of an alpha anyone would dream of mating. Izuku cups
himself, gently dipping the tips of his fingers into the warm, stretched recess of his body.

“That’s mine,” Kacchan snarls, stirring the water around him as his pace quickens. “Do not
touch what belongs to me.”

Izuku raises a brow, flicking his long ears up to a dominant, challenging stance. Kacchan has
learnt enough of rabbit-folk to understand the gesture, lips peeling back to show his fangs in
his own unspoken challenge: Submit, or fight.

Izuku dives from the ledge behind him just as Kacchan leaps the last of the distance between
them. A harsh, ringing squeal leaves him as his mate catches him, hauling him up from the
water with a demanding growl. Kacchan’s muzzle smacks the side of Izuku’s head, knocking
him aside to bare his throat. Izuku scrabbles, kicking wildly in the water, instincts rising at
the smell of predator and lust billowing around him. Before he can work himself into too
great a fervour Kacchan buries his fangs into Izuku’s shoulder. Once, twice on one side
before switching to the other and giving it two bites as well.
Izuku flails, moaning in pain and lust as Kacchan twists him around, still holding him
entirely aloft. Kacchan’s strength has always turned him on. Now, in heat and engaged in a
dominance struggle, the display is nearly enough to make him cum untouched.

Kacchan pulls Izuku’s thighs around his waist, dipping him back and dropping his muzzle to
give another nip to Izuku’s chest. A rough tongue bathes the swollen nipple, teasing it to a
needy peak before releasing Izuku with a growl. “Yield,” Kacchan snaps, rutting his hips
forward to drag his cock along Izuku’s ass.

Izuku chitters, digging his short, blunted claws into Kacchan’s shoulders, still tempted to
fight… but he is so unbearably empty now it hardly seems worth it. His cunt-fur drips from
the spring, but it isn’t just water coursing down his thighs with Kacchan between them once
more. He groans a complaint for his continued emptiness, shaking his head with loud thwaps
of his ears before lifting his chin to Kacchan’s glaring gaze.

Submission.

“Mine,” Kacchan hisses, lifting Izuku’s body up and back enough to push into his cunt.

Izuku yelps at the sudden invasion, squeezing his eyes shut as his mate fucks him with harsh,
brutal thrusts. He can hear his cunt sucking Kacchan’s cock, spurting slick and old cum onto
his mate’s belly and thighs, soiling the spring with their spend. Kacchan walks through the
water, bouncing Izuku on his cock all the while. He ignores Izuku’s whines and yelps as he
clambers over the stones, panting in triumph when they reach dry land.

With no warning, he pulls Izuku from his cock and drops him a short distance to the stone on
his back. Izuku presses himself up on his elbows, intending to snap a demand for more, but
Kacchan apparently doesn’t need his feedback. The wolf crouches before Izuku, bending his
legs up toward his chest before pressing them further—past his head, bending him almost
entirely in half.

Izuku squeaks, breathing hard at the awkward position. He’s completely exposed here, upside
down with his cunt and ass in the air, Kacchan’s clawed hands gripping the backs of his
thighs to keep him in place. “Kacchan,” Izuku whines, flailing a hand between them.
“Relax, Deku. Gonna fuck you more,” Kacchan growls. Drool slips between his fangs, his
muzzle creased in a satisfied smirk.

Izuku attempts to cover his groin but Kacchan slaps his hand away, baring his teeth to enforce
the command. Izuku flushes, rage and embarrassment duelling for position at being forbidden
some—any—modesty. “That is not what I—”

“Need a cock in your cunt that bad, slut?”

Izuku gawks at his mate, legs shivering in Katsuki’s claws. He… he has no rebuttal to that.
Kacchan knows it, too, looking down his muzzle at Izuku’s dripping, gaped-open cunt.
Silvery cum and slick have begun dripping out and up the length of his groin, wetting his
cunt-fur and leaving his mound a sticky mess. His insides twitch, clenching around the
emptiness inside. Katsuki’s eyes narrow, examining Izuku with a cool, appraising glare. His
gaze stops at the top of Izuku’s sex, lingering on the bitten nub with obvious, arousing,
distaste.

“Tried to cum without me? Touched this without my permission?” He reaches out, flicking
Izuku’s clit hard with his long, black claws. Izuku yelps, whining submissively. He tries to
close his legs, to protect his sore, bitten clit from further punishment, but being bent in half
and having his mate’s strong hands holding his thighs in place—there’s no escape.

Kacchan growls, holding Izuku’s gaze as his hand rears back and up. Izuku pleads for mercy
even as he aches for the touch, no matter how painful. Kacchan has truly distorted his senses
if being slapped and spanked on his cunt is his idea of pleasure.

“This,” Katsuki snaps, raining pleasurable agony down on Izuku’s sex with a flat, heavy
palm, “is mine. I decide its use.” Kacchan changes angles; suddenly all the force of his hand
lands on Izuku’s clit, swelling the glans into a tortured little ruby as blood rushes to the site.
“I give you pleasure, I worship you, and I ask only for your submission in return. That you
allow me to have your body, to use as I see fit.”

Izuku thrashes, close to cumming as claws pinch into his clit. “Do not touch this again. You
don’t deserve it. Say it, Izuku. Apologize to your mate.”
Izuku sobs, pulling his ears to endure the punishment. He’s spasming inside, an orgasm of
pain he never thought possible. The words come out in blubbering gasps, sobbed out between
yelps as his alpha strikes his sex. “I… do not… des—AHH—deserve… my c-clit. My—I will
n-nooooh… not touch where my, my alpha decides I—I am not p-permitted!”

Katsuki’s brow quirks, hand raising once more before Izuku remembers what else he was
asked to say: “I’m sorry!! I’m sorry, I won’t—I’ll never, never touch it again, it’s yours—
yours,” he sobs. Katsuki gives him another strike despite his apology, meanly pinching
Izuku’s clit between his knuckles. Izuku whines, legs jerking until Katsuki releases him with
a last, hard tug on the terrible, tiny bit of flesh that earned his ire.

His mate growls, spitting onto Izuku’s ass and smearing the wet into the curve of his hole.
Izuku gasps at the feeling, dizzily craning his head to watch. Katsuki has dangerous claws, he
wouldn’t—and it’s clear his mate doesn’t intend to use them, either. Katsuki slides his fingers
through the folds of Izuku’s sex, wiping the mess there onto his cock before beginning to
insert himself into Izuku’s untouched back passage.

Shaking, Izuku holds his fingers up with a nervous chitter. “P-please, I can—”

Katsuki rumbles, deep in his chest. “What for?” He smirks at Izuku, watching his face as the
head of his cock slips in. “You clearly know how to open your hole without it,” he purrs.

Izuku grips his ears, shaking his head as Kacchan’s cock pushes in, in, in. Ohhh, it burns, it’s
too much—yet Izuku is dripping wet, providing plenty of lubrication to ease Katsuki’s way
into his ass. His face flames as Kacchan groans, drawing out and thrusting back inside with a
mortifying squelch.

“What a perfect hole,” Katsuki growls, licking his lips as he watches his cock vanish and
reappear. The knot at the base of his shaft is nearly full now, the swell of it pulling Izuku’s
rim wide with every thrust.

“Nnn, Kacchan!” Izuku shouts, bouncing the back of his head on the stone beneath him. He
can’t move anything else on his body—save the gaping, empty mess of his cunt—and the
myriad sensations overwhelming him now demand relief.
“Mmm… just relax,” Katsuki insists. “You’re made for this, made for my knot, to take it…
fuuck yes,” he laughs, pushing in to the hilt with a last yelp from Izuku. “Want the rest?”

Izuku squints at him, panting as heat begins filling his backside. He can feel Katsuki’s knot
throbbing, his mind and body struggling to reconcile the sensation of his mate’s orgasm in the
wrong hole. Or rather, it should be wrong but Izuku is such a mess, such a whore, that any
hole of his that Kacchan decides to fuck is right. Still, he doesn’t quite understand Kacchan’s
meaning. Perhaps he’s just knot-drunk, or it’s some wolf custom Izuku hasn’t quite
understood.

Katsuki barks a laugh at Izuku’s perplexed expression, squeezing his thighs as he adjusts his
stance. “This, more.” Katsuki’s face creases, slackening with obvious pleasure. Realization
dawns as the first bit of hot, golden fluid pours down Izuku’s groin, escaping his ass past the
stopper of Katsuki’s knot. His mate has pissed inside of him.

“Your ass is for my relief,” Kacchan purrs, a rakish, self-satisfied smirk on his face. “Your
cunt is for breeding. It’s best you learn your use now, Deku. A wolf’s holes belong to their
mate, to use as they please. You are my omega, my mate.” Pride radiates from Katsuki, an
aura of delight and hunger that Izuku can’t help being attracted to, despite his irritation and
utter shock at being so used.

“You belong to me now,” Kacchan continues, pressing a palm to the little bulge of Izuku’s
belly. His hips move faster, deeper, working Izuku’s ass on his cock with unfair skill. “I’ll use
your holes as I see fit.”

Izuku moans angrily, wishing his body wasn’t so visibly betraying him. That he didn’t love
being used by Kacchan, even if some part of him is still distantly revolted to be pissed in.
Does it infuriate him to be made into a set of fuckholes to be used and enjoyed as Kacchan
decides? Yes. Does it make him flush with heat and pride to know Kacchan wants to use his
body thusly? Also yes. He never knew becoming a mated omega would involve such intimate
duties, or that he could see himself growing to love being used as his alpha, his mate, decided
he was meant to be used.

Tears pour down his temples as Kacchan fucks his ass, knot popping on the swollen rim with
lewd, echoing sounds. Golden liquid pours over the curves of his belly, staining his skin. The
piss itself will wash away, but Izuku will never forget the feeling of it inside him. The heat
and gush in his backside, the sudden tightness in his gut, the urge that comes without relief as
Kacchan’s knot keeps him plugged full and tight. The mortifying, responding gush from his
own body when the pressure grows too great.

Kacchan purrs, laughing and groaning satisfaction above as he watches Izuku piss himself. It
almost feels like an orgasm as his mate begins teasing his clit, slicking the bruised, aching
glans with piss and slick. “We’ll make you a proper wolf yet,” he declares, pausing his thrusts
to relieve himself once more. Izuku utters a wordless, whining complaint, too destroyed with
pleasure and piss to do more than cry.

---

Kacchan grumbles under his breath as he works another snarl from Izuku’s fur, taking care
not to tug on the ruff beneath his neck. Izuku lounges in his mate’s lap, sore and stiff but
happy to be attended to so rigorously.

Katsuki said they needn’t engage in all wolf customs immediately upon their mating, but
Izuku was determined to fully immerse himself in his new alpha’s clan. If it meant returning
to them with the scent of their leader’s piss and cum on his person, so be it. Although he was
a little miffed to be so roughly given his ah… 'liquid' claims. And he did not know it would
be going inside him as well!

Kacchan gives apologies in an interesting fashion. Not one for many soft words, he’d brought
Izuku back into the spring shortly after another anal knotting, apparently satisfied with his
mate’s soiled state. He then spent the last hour detangling Izuku’s fur and hair, bathing and
rubbing every inch of his body.

Well, Kacchan did have one true apology to offer, which Izuku gladly took. An offer of a
mouth on one’s clit, tenderly licking and sucking all the sore, swollen places without any
cruel twist or nip of teeth or tongue is one Izuku was very glad to accept. Though of course it
wasn't without some small amount of pain—as Kacchan decided to lick at and tug the little
silk threads through the holes in Izuku’s clit until he all but shrieked through another orgasm.
Now they’re just relaxing together, truly enjoying the bath with Katsuki’s rut-rage eased and
his animal instincts no longer warding him away from water. Izuku sits in Katsuki’s lap with
his back to his alpha’s chest, legs draped over Katsuki’s. One of the wolf’s hands rests
between his legs, holding Izuku’s cunt, gently rubbing every so often. Izuku isn’t sure if it’s a
comfort thing or just a Kacchan thing, but he enjoys it regardless.

Katsuki huffs loudly, apparently finished with the last knots in Izuku’s short mane. Izuku
turns to kiss his mate, opening his mouth to let Katsuki’s tongue twine with his. His alpha’s
face has yet to return to its more human state, but Izuku rather likes getting to know this side
of him. It feels more natural, more honest; like his predator mate feels comfortable enough
with Izuku to show his more animalistic appearance.

Izuku rubs at one of Katsuki’s ears, purring his gratitude for the thorough grooming. Kacchan
utters a little grumble, obviously embarrassed to have his doting behaviours focused on. His
hand shifts on Izuku’s sex, combing claws through the fur above his cunt with obvious
interest. Izuku winces a little as Katsuki explores him more thoroughly, spreading his lips
apart and stroking the hole within—now nearly swollen-shut from their earlier efforts.

“This part of you is beautiful,” Katsuki growls finally, gently circling Izuku’s clit with his
thumb. The stimulation aches, but his mate’s doting is worth the discomfort. Katsuki’s voice
drops, his cock slowly stiffening beneath Izuku. “I would worship it…”

“And how do you intend to do that, alpha?” This talk and exploration of his sex draws
attention to his current empty state. Izuku shifts his hips, lifting a little to indicate his desire
for something within. Katsuki groans, quickly stroking himself to hardness to give Izuku his
rightful seat. It aches something terrible to stretch wide on a cock and knot once more, but
the soul-deep relief of intimate union is worth the small pain.

They both noise softly as Katsuki nestles against the gate of Izuku’s womb, settling back
against the wall of the spring with a sigh of relief. Warming his alpha’s cock is a role Izuku is
very pleased to take up as a newly mated omega. There can be no doubt of Katsuki’s
devotion with his cock an unflagging, throbbing spear in the depths of Izuku’s body.

“When my bites have healed, I intend to put jewels here,” Katsuki purrs, slowly running his
fingers over Izuku’s sex. “Your clit: a ruby ring through its head, a bar of gold through the
hood. Your lips…” He teases one with a little tug, nosing Izuku’s neck with a low, hungry
rumble. “Rings along their length to hang fine chains and gems from… or to lace you shut, to
keep your cunt safe for my use.”

Izuku whimpers, rocking slowly in Katsuki’s lap. He drags Katsuki’s hand to his clit before
leaning forward, bracing both palms on Katsuki’s knees as he begins to ride. He thought he
was through his heat and too sore for anymore sex, but Katsuki’s low voice telling him plans
for his body, elaborating on how he means to adorn Izuku… He needs his mate now.

“Please, please, Kacchan,” Izuku moans, rolling his head from side to side as his mate begins
tending his needs. “Ohhh… I need you, need you inside me—fuck, gods, I hope it takes, I
want to… to be full, to carry your jewels,” he adds, including Katsuki’s possessive fantasy.
“Your seed… your pup…”

“Fuck, Izuku,” Katsuki gasps, lifting his hips to meet each stroke of Izuku’s hips. “Little
demon.”

“Yes… yours,” Izuku groans, seizing in Katsuki’s lap.

The orgasm is slower and gentler than the others, but it goes on and on, forcing them to
huddle together as Izuku’s body holds them over an abyss of pleasure. Katsuki’s muzzle
droops onto Izuku’s shoulder, low, exhausted huffs puffing into his ear. He can feel his mate’s
heart against his back, rabbit-fast and endearing for its effort.

Izuku snuggles back against his mate, drawing their hands together to the curve of his belly.
Katsuki presses a kiss to Izuku’s shoulder, pride filling his scent at the proof of his claim.

---

“Kacchan,” Izuku mumbles, some hours later as they lay half-asleep in their bed.
It’s nearing dawn now, the night almost fully spent while they took their pleasure together.
Izuku should be sleeping—indeed he was asleep for some time after Katsuki carried him
back to their bed—but heats pay no attention to such constraints as sleeping and waking. His
body aches to be satisfied again, and no amount of rest will fill that need.

Katsuk grunts, leaving his face buried in their tattered pillows. His mate’s fist curls against
Izuku’s back, forefinger tapping slowly to show he’s listening. “You can use my ass like
before,” Izuku whispers, glad the slow-dying fire hides the expression on his face. “I liked it.
All of it.”

Katsuki stiffens, a muffled groan pouring from the depths of the bed before a single red eye
locks on Izuku through the gloom. “If you don’t wish to be fucked again…” he warns.

Izuku licks his lips, swallowing heavily as he drags a large, clawed hand to his groin beneath
their blankets. “I’m… I’m empty, Kacchan. It’s cold without you keeping me full.”

A dark, hungry growl fills the den as Katsuki Bakugou erupts, turning his mate to all fours
with a demanding bark. “You asked for this, slut,” Katsuki hisses, gripping the puff of Izuku’s
tail with one hand and guiding his cock into his omega’s swollen ass with the other.

Izuku moans, whining, pleading, and clawing at the bedding beneath them in a very
believable show of denial. Anyone who heard such cries or saw such thrashing, bucking
movements could scarcely be faulted for determining such a pairing was one of force. Yet
even with all the chances in the world to escape, to be anywhere else than on his chest with a
fist-thick knot splitting his ass, filling him with cum and piss as harsh words rain down from
above—Izuku is content to remain as he is.

Content—overjoyed, honestly—to be debauched and utterly worshipped by his demanding
