It seems par the course for their ‘relationship’ that the first time Rei sees her lover’s apartment, Kaina’s bleeding all over Rei’s vigilante suit. 

They stagger over the threshold and Rei kicks the door closed with her heel, panting with the effort of propping Kaina up. There’s a frightening amount of blood spilling down the side of Kaina’s tactical suit. It looks black, like the rain drenching both of them and now puddling on the floor, but Rei can feel how warm and sticky it is.

The stench of blood fills her sensitive nose. Kaina’s snow leopard ears and tail, and Rei’s own wolf ears and tail, are matted with rain and drooping from pain and exhaustion.

Kaina disentangles herself from Rei and slumps against the door. She wrings water out of her tail and quips, “another successful mission.”

Her flippancy sends a wave of frustration and helplessness washing over Rei. “What the hell did you think you were doing? I didn’t ask for your help!”

Kaina musters up an affronted glare. “Like I was just supposed to stand there and watch you get shot?”

“I was doing fine on my own! You think I wanted you to get hurt?" 

“You’re so damn stubborn, you-” Kaina’s sentence devolves into a growl of frustration with bared teeth. She shoves Rei up against the door and kisses her, a sloppy kiss that tastes like rain, sweat and blood. The association is all it takes to get Rei drooling for the taste of Kaina’s pussy, make her cock harden in her tights. 

With a strangled groan of pain, Kaina pulls away. She leans her forehead against the door and Rei holds her up.

The fact that Kaina’s too wounded to fuck Rei’s brains out against the door is making her seriously worried. “Where's your first aid kit?"

“First aid kit…? Bathroom. Bedroom, bathroom,” Kaina grunts reluctantly.

Rei fumbles around on the wall and finds lights to flick on. The apartment looks just like Rei had imagined it. A dimly lit basement. One room is a home gym, another has an arsenal's worth of weapons and gear. There's a spartan living room and kitchenette. 

Not a single picture, not of family, not of friends, certainly not of Rei. 

With Kaina leaning heavily on Rei, they hobble to the bedroom. Kaina crumples on the bed as Rei searches frantically for the first aid kit.

"If you'd invited me back here before I'd know where it is," Rei grouses. 

"Don't start," Kaina warns.

It's unfair of Rei, but her hurt is real. It's been almost a year of stolen kisses on rooftops, achingly romantic snatched half-dates and quickies in alleys, all with the looming fear of discovery. 

Rei finally finds the kit. Kaina's already got her black vest off and Rei grimaces at the ugly gash in her side. 

She cleans and stitches it as best she can. The puckered row of stitches is an accusation. If only Rei had been faster, if only she had the right support items and training, maybe Kaina wouldn't have had to take that bullet.

Maybe Kaina wouldn't have had to put a bullet through the villain's skull, leaving the rain to wash the blood away from their lifeless body.

Rei’s pavlovian response to Kaina’s blood doesn’t help. It’s an association developed by all the times they’ve fucked after near death scenarios, all those times she’s tasted blood on Kaina’s lips and kissed her way down her scarred, muscular body. 

Kneeling in front of her to treat her wound, between her legs no less, makes her ache to finish as fast as possible, pull Kaina’s pants down and put her heart and soul into eating her out. 

It’s not like being injured has ever stopped them from fucking before, but it’s glaringly obvious that Kaina doesn’t want her here. Rei shifts uncomfortably, hoping she hasn’t noticed the bulge in her tights, and focuses on her job.

When Rei finishes dressing the wound, she cups Kaina's face and kisses her worryingly grey lips. "Thank you. For saving me."

"Always," Kaina says with a wan smile, then sighs exhaustedly. "Now you better get out of here."

"Out of here?" Rei asks in hurt disbelief, "but you're hurt."

"I'll be fine," Kaina says gruffly. "It'll be bad for both of us if anyone finds you here."

"I know that! But I can't just leave you like this."

"Don't argue with me. I won't be able to live with myself if you get caught, and I can't be seen with a vigilan-"

“Save the speech,” Rei snaps. She knew the spiel by heart. Their ‘relationship’ is a fast way for both of them to end up in Tartarus, or worse. That fact hadn't stopped Kaina from sucking Rei off or letting her eat her out in back alleys… but it was her excuse keeping her from getting any closer. 

"You want me to leave so badly? I'm leaving. Have fun taking care of those stitches yourself."

She starts to storm off, but Kaina's hand closes around her wrist. 

“Rei… I didn’t mean it that way.”

"What other way can you mean it? It's my first time in your den and all you want is for me to leave."

“I… look, it’s nearly morning. Just wait till nightfall. Please. You’ll be safer.” 

“Fine. If you can stand to have me around for that long.”

Kaina abruptly looks just as exhausted as she ought to be for someone who’s just gotten stitches, rubbing her temples, and Rei feels guilty for snapping. What the hell is she doing? She can't seem to stop herself. 

Kaina gestures blearily at Rei’s vigilante outfit. "You should get out of those, they're covered in blood. And please promise me you'll try to rest."

"Yes, mommy ," Rei grumbles half-mutinously, half-totally seriously, trying to make up for her atrocious behaviour. 

It just makes things more confusing. Just saying that makes Rei drool for Kaina's pussy and makes her hard. Kaina gets all flustered and stammers, "sh-shut up," but at least it puts some colour back in her cheeks in the form of a blush.

Kaina hobbles to her wardrobe and rummages through clothing. Past her body, Rei catches a glimpse of a surprisingly packed row of dresses. 

Kaina comes back with an All Might sleeping shirt (faded, but not enough to obscure his golden retriever features), sweatpants, and boxers. 

Rei takes the clothes, hoping her agony at the rejection isn’t showing on her face. She wants to cuddle Kaina through the night, but it's clear from her dismissal that that’s not going to happen. 

Kaina gasps in pain and wobbles, and Rei instinctively moves to support her. She's holding Kaina up for sure, but it's more like an embrace. Her scent enfolds her, a scent Rei now always associates with safety. 

But there’s more to it this time. It’s subtle and delicate, and Rei would never have noticed it if she wasn’t part wolf, or even if they’d met where they normally did - on the rooftops, where a million other smells vie for her attention. 

Kaina is in heat. 

Rei drops the clothes on the floor, cups her cheeks and draws her down for a kiss. That intoxicating hint of scent just isn’t enough. She needs to make Kaina drenched in sweat, needs to feast on her come. She settles for deepening the kiss, dipping her tongue into Kaina’s mouth. They play their tongues along each other’s, heat building, breath turning ragged. 

Kaina rests a hand on Rei’s chest and she gasps in anticipation. 

The anticipation turns to pure agony as Kaina pushes her away, back over the threshold of her bedroom doorway. Her ears are tucked, her tail between her legs, shaking like there's a war going on inside her.

Even if Kaina’s body language didn’t tell the whole story, her scent does. She’s afraid. 

She has to be, to have such iron control over her heat. Any other omega, around an unmated alpha such as Rei, would’ve been practically climbing onto her cock. Rei can’t even imagine the willpower Kaina must have to be keeping it together the way she is. To push Rei away.

She really doesn't want me, Rei thinks, her heart breaking.

Kaina stoops with a grunt of pain, gathering the clothes up and handing them back to Rei. “There’s, uh… there's another bathroom down the hall.”

“I’ll take the couch,” Rei says miserably, and heads to the other bathroom with her tail and ears hanging limply.

The clothes are a comfort at least. They smell of Kaina and the holes in the back of the bottoms make Rei think fondly of her long, graceful snow leopard tail, with its dark blue and pink spots.

When she comes out of the bathroom, she finds Kaina’s bedroom door closed and a pillow and blanket on the couch. The closed door feels more like a brick wall, but the pillows and blanket smell blissfully of her - she's obviously been sleeping with them. Rei would consider it yet another set of mixed messages if she hadn't just been so soundly rejected.

Rei throws the blanket, pillow and couch cushions onto the floor and rucks them up to make a nest. She curls up, listening to the rain drum against the high, narrow windows and hammer on the street outside. 

The whole place is suffused with Kaina’s scent. Now they’re not in some life or death battle, Rei can bask in it fully, burying her nose in the pillow and taking the deepest breaths she has all night. She longs to be in Kaina’s bed, nuzzling at her neck and breathing this heavenly scent from her skin. 

Tears sting as she runs Kaina's refusal through her mind over and over again. What did I do wrong? Have I just been getting my wires crossed this whole time? Does she not feel the same way I do? 

Is she not in love with me, like I am with her? 

If it were that simple, why would Kaina be so afraid?

Rei remembers the first time they had sex with particular clarity. They'd been hiding from a mob of villains too powerful for them to take on even together, pressed together in a tight, dark space. It had been raining then, too. 

Kaina had reached up, as if in a trance, for Rei's face. She had frozen, knowing that if she struggled, the sound would alert the villains to their presence and they'd both die. Knowing that her life as she knew it was over, she had allowed Kaina to gently remove her mask. 

The mist of their breaths mingled in the chill air. Kaina's eyes widened in recognition of Rei, the unmated last scion of the Himura clan. Despised by many as the death knell of her lineage, and of her clan's monstrously powerful quirk.

At long last, Kaina had seen the yearning in her eyes. 

And suddenly they'd been kissing hungrily, desperately, years of snatched glimpses, sparring, tentative cooperation finally coming to a head. Rei could finally, finally kiss those gorgeous lips she'd fantasised about for so long. 

They had gone quickly from kissing to dry humping. Rei had stuck her hand down the front of Kaina's pants, gasping with delight when she found slick furs and drenched folds. 

Kaina began a rumbling purr, moving sensually into Rei's palm as she fingered her and pressed her palm against her clit. As she spilled sticky heat into Rei's palm, drenching her finger, she had started to keen. Rei had clapped a hand over her mouth to stifle the sound. 

When she had looked up, expecting to see satisfaction, she had found Kaina's head bowed. With her eyes fully in shadow and the torrential rainfall plastering strands of pink and purple hair to her face, Rei hadn't been able to get a full read on her expression. Confusion, and yes, satisfaction. Fear and distress that Rei had attributed, at the time, to their precarious situation. 

Kaina had fallen to her knees, pulling down Rei's tights and sucking her off. She'd had to gag herself with her own mask to stifle her sounds of pleasure. She'd never forget the feel of that hot, wet mouth wrapped around the length of her cock, the lapping tongue, the obscene wet moans as she sucked. Kaina had been purring, too, the vibrations adding another layer of pleasure, making her shoot more come than she'd thought her balls could possibly hold. 

Kaina had looked up at her with adoration, come dribbling over her pretty lips and down her chin. Rei had hauled her up and kissed her, and Kaina's tail had reached around to intertwine with hers.

Thus began an almost year-long affair, conducted in stolen kisses, quickies in alleys and tentative rooftop half-dates that always ended with their tails entangled, one way or another. 

Soon after realising she had fallen in love, Rei had begun to lose hope that they could ever have something more. Kaina was always so cagey and avoidant. How long could they keep this up?

Kaina liked to give much more than she liked to receive. Rei was constantly starving for that gorgeous pussy but Kaina'd often pushed her away when she tried to initiate, turning the tables on her.

She refused to talk about it, but Rei could piece together a guess. Hitched breath that sounded more of distress than arousal, the smell of fear, the way her ears would fold back and her tail would tuck and tremble.

The thought of anyone hurting Kaina in that way made her rabid with fury. She fantasised about finding whoever had done it and ripping their throat out with her ridiculously inadequate, blunt human teeth. Or exploring her quirk’s potential for pain and lethality as if she were a villain.

It would be easy enough, especially with Kaina weak and wounded, to kick down that door and take her in the heart of her own den. How would she ever recover from that? Just the thought makes bile rise at the back of Rei’s throat. 

"You should've stopped," Rei sobs into Kaina's pillow, "you should've stopped, Rei, you damn fool."

*

Boxing her so-sensitive snow leopard ears, relishing in her sweet yelps of pain. Holding her down, yanking her tail roughly. 

"Mommy, it hurts," Kaina cries, "mommy, it hurts, stop-"

Kaina calling Rei mommy has only ever made her hard, only ever made Kaina wet. Growling, snarling, she forces her cock into that tight, wet cunt and starts to plough her into the floor. Forces her to come through her cries of “no” and “stop.”

Tears spill down Kaina's cheeks even as she spills come over Rei's cock. "Why?" She pleads, looking over her shoulder with huge, sad eyes.

Rei wakes up coming, sticking Kaina's boxers and pants to her cock. 

"Fuck, Rei, how could you?" Rei snarls, even though she knows it was just a dream. She sticks her hand down her pants and finishes herself off.

As she spills her last, she realises she's in deep trouble. Her cock won't go down, her knot is swollen and pulsing, and her clothes and makeshift nest are drenched in cold sweat. 

All the signs of a sympathetic heat.

She was right. I should've left, Rei curses herself as she takes a long, ice cold shower that finally forces her cock to limpness. She's in heat and she won't let you help her. Won't let you sleep in her bed. Doesn't even want you in her den. You need to get your head checked. She obviously doesn't want you.

She hastily dons last night's clothes, intending to sneak out without a goodbye.

She can’t make it past the doorway.

Did Kaina feel so little for Rei? Had it all been just sex to her? Rei wracks her brains, trying to figure out what she's done wrong, or if she's done something to make Kaina so afraid of her. 

Rei slams her fist into the door. If Kaina would only talk to her - tell her what she's done, what she can do. Or just tell her to leave once and for all and get it over with. Then she can get together with someone else and Rei can die of jealousy.

I'll make her talk to me, Rei thinks feverishly, whirling around and storming towards the bedroom. I'll make her tell me how she really feels. 

And if she really doesn’t feel the same way, Rei will kill the part of her heart that loves her, and leave her alone for good. 

Rei’s got tears in her eyes when she hammers on Kaina’s bedroom door. “Kaina, we have to talk!” she shouts, and barges in.

She runs right into Kaina, and the sight of her wipes every concern, every negative thought, from her mind - and makes her cock throb to hardness once again.

Rei has only ever seen Kaina in her badass tactical gear, but now she’s wearing the prettiest dress she’s ever seen, and it’s blowing her mind. It matches Kaina’s colouration perfectly, white with a dark blue and pink flower print. It only comes to mid-thigh, and she’s not wearing a bra, so Rei can just see the shapes of her puffy nipples through the fabric. A light sheen of heat-sweat shows off her immaculate musculature.

The thought of Kaina puttering around in this little apartment in her cute dresses fills Rei with such affection and possessiveness she thinks her heart’s going to burst. She wants to see Kaina in every dress she owns. Wants to know every last detail about her.

“I… was just coming to check on you,” Kaina stutters, clasping her hands coyly behind her back. Her tail twitches back and forth nervously. 

“You were?” Rei says with embarrassing hopefulness. Her tail starts to wag so hard it makes her butt wag too, and she bursts out, “Kaina, that dress! You look so pretty!” 

“Yeah?” Kaina beams, her tail lashing energetically and her ears perking up. 

“I’m losing my fucking mind over how gorgeous you are. You’re so…” she locks eyes with Kaina, her voice dropping to a husky lower register with how emotional she is right now, “you’re so beautiful. ”

Kaina’s eyes darken and rake over Rei’s body, coming to rest on the very visible bulge of her hard cock. “So are you.”

Heat, the smell of heat, the smell of come. Rei knows what she’ll find if she pushes the hem of that dress up - drenched panties, sticky heat. A puffy, ready cunt begging to be filled. Kaina must have known that this almost-slutty dress would provoke Rei, when she would have been able to smell even through the door that she’d gone into heat herself.

Rei steps fully into the bedroom, shutting the door harder than she intends behind her. She advances on Kaina and kisses her.

She can immediately tell something’s wrong. Kaina’s kissing Rei back but she’s also shutting down, like she sometimes does when they’ve kissed before. The fear scent roars back into full strength, invading Rei’s nostrils and overpowering the sweet scent of their heats. 

Rei tears herself away. The sight and smell of Kaina in such pain and fear is agony. She can’t bear to be the one causing it.

Kaina stands there, reeking of dread, with her ears flattened to her skull and that pretty tail tucked stiffly between her legs. “Rei, I’m sorry, I don’t… I don’t think I can -”

She needs to say something, anything, to help Kaina feel safe, but damned if she knows what that is. 

She takes Kaina’s hands in hers and says the first thing that comes to mind. 

“You don’t have to think. You don’t have to worry. Just shut up, be a good girl and bend over when I tell you to… mommy.”

Just saying it makes Rei’s cock throb. Kaina’s eyes widen and her breath hitches gratifyingly, her cheeks going that same pleasing pink as before. Her tail goes still, trembling, before starting to lash energetically. 

“O-okay,” Kaina manages to choke out at last. 

“God, mommy, you look so fucking pretty in this dress…” Rei puts her hands on Kaina’s waist, drawing a shiver out of her. It’s absurd just how gorgeous she is, so tall, so broad, but with that trim waist… and with that cute tail sticking out the back, practically begging to be grabbed… 

Kaina drops her gaze self-consciously. “You…you really like it?”

“I can’t take my eyes off you. I can’t believe how gorgeous you are.” Rei runs her hands up Kaina’s front, tracing her majestic collarbones and shoulders. “I’m so lucky I get to see you in this. Thank you for wearing it for me… I know you didn’t have to. I know you wanted me to see you in it.

“And I’m so lucky I get to smell you. Be around you while you’re in heat.” Rei rests the tip of her nose in the hollow of Kaina's throat and breathes in deep. The scent of her skin, lingering sweat, and the sweet, slightly musky scent of her heat. And she can smell how wet Kaina is already, just from a little touch, just from Rei’s presence. “Oh, fuck, you smell so good…”

“I’ve been trying to-”

“Shh, mommy, remember? Just do what I tell you.” 

“So what… what do I do?” 

“Just stand there and keep your pretty mouth shut.” 

She does, obediently. She’s so cute, so god damn mother fucking cute in that dress with that submissive expression. 

Rei kisses across the exposed skin at the top of her breasts, pinching her nipples through the fabric until they’re stiff and poking through. She flicks them with her thumbnail, pinches them, twists them until Kaina’s squirming and panting. 

She suckles them, getting the dress wet with her spit. The hard buds feel so good through the flimsy fabric. As she sucks them she feels Kaina up under her skirt, groping her ass, playing with the hem and waistband of her panties. They feel lacy and revealing, and Rei can’t wait to see them. She strokes her hard muscled thighs, squeezing the chubby, sexy bit of fat where they meet her hips. 

When she’s done there are soaked, translucent circles over Kaina’s dark, pert nipples. Kaina’s panting and humping thin air with her tail held out stiff and trembling lewdly.

She had been intending to tease Kaina more, but it’s too much. She grabs Kaina’s ass and pulls her forward. She squeaks in surprise, then moans as their bodies press flush together along their lengths. They’re at the perfect height for Rei’s throbbing dick-print to press up against Kaina’s pussy through her dress.

“Oh, Rei! Fuck!” Kaina gasps as she grinds on Rei’s cock, hiking her dress up. Rei’s head spins and her mouth waters at the touch of soaked panty-clad pussy. She can feel the stickiness on her cock even through her tights. Kaina drapes herself all over Rei and tilts her hips just right, so she can rub her clit against the shaft. She moans wantonly as she rocks against her.

Rei’s panting too now, grinding right back into Kaina’s motions. She grips handfuls of Kaina’s ass, urging her on. “That’s right, mommy, just like that. Can you come like this?” 

Kaina nuzzles at Rei's hair, kneading her shoulders with her hands as if they’re big cat paws. Her tail slinks around Rei's waist and squeezes her tight. “I don't know. S-so close…”

Rei latches onto Kaina’s nipple again, worrying it with her teeth while she flicks it with the tip of her tongue. "Come for me, mommy," she orders. 

Kaina gasps, goes stiff for an instant before grinding furiously on Rei's cock. Her mewls are so sweet, a spill of slick sticking Rei’s tights to her cock and making her frantic motions sound slippery and obscene.

She thinks she might be able to come, too - not just from Kaina rubbing her exquisite pussy on her cock, but also from her frantic panting, her clutching, the adorable way she kneads Rei's shoulders in time with her grinding.

A warm glow of pride fills Rei. She's finally able to take care of her Omega when she's in heat - as she's craved to do for so, so long.

Rei holds Kaina up as she goes limp, trembling and occasionally urging her hot, sticky pussy against Rei with an aftershock. 

Rei noses at Kaina's smooth, unmarked neck. She smells like sweat, sex and the addictive scent of her heat. She'd look so pretty with Rei's mating bite.

She tears her mouth away from the tempting skin. It would be so wrong… she didn't even want me here in the first place. Maybe she still doesn't. Maybe it's just her heat.

Rei will take what she can get, and she's too deep in the throes of her sympathetic heat to feel pathetic about it. Besides, Kaina needs her right now. “I can’t believe you came from that… came all over me. You’re such a slut, mommy…”

“S-stop,” Kaina says, though from her scandalized tone it’s clear she wants Rei to do anything but. She’s already grinding again, too. 

“You want more?”

“Yes! Oh, fuck yes, I want-”

“Turn around and bend over for me, mommy.”

Kaina puts her hands on the bed, kneading, and arches her back in a long, fluid motion that ends with her tail. It unfurls sinuously before swaying temptingly back and forth before Rei’s eyes. 

There’s no hole in the back of the dress - the tail just sticks out from under the hem - so its motion lifts the dress up, totally baring her stunning ass, her purple, lacy panties. They’re completely soaked, clinging to the lips of her cunt and leaving nothing to the imagination. Strands of come have spilled down her inner thigh.

Rei’s paralyzed by the glorious sight, her cock pulsing so hard in her tights it’s starting to hurt where it’s restrained by the fabric.

And then the fear returns. Kaina’s kneading motions turn jerky and fretful. Her ears flatten against her skull and her tail slinks between her legs, blocking Rei’s view. The dress falls back down, too.

Gently, so gently, Rei moves Kaina’s tail aside to bare her pussy again. It shakes and strains in her hand, trying to get back between her legs. There’s a patch of come on the furs from where it came to rest on her panties. 

“Am I… am I doing it right?” Kaina asks shakily, her voice breaking slightly on the words, “I-I wanna be good…”

“You’re doing so good, just like that, my good girl. Now lift up your dress.”

Kaina takes one hand off the bed to pull her dress back up around her hips. “L-like this?” Kaina’s cheeks are burning and she looks both embarrassed and thrilled. 

Rei’s so consumed with lust she can’t respond. Kaina jumps and squeaks in surprise as Rei presses her nose and mouth to Kaina’s soaked cunt, taking a deep breath that ends on an appreciative groan. She licks Kaina’s slit, her tongue pushing the sticky fabric between her pussy lips, and tongues at her hole. 

“Fuck, that feels so good, oh…” Kaina moans, humping her slit against Rei’s tongue. 

Rei laps it, getting it thoroughly soaked in her spit, and teases at the exposed outer labia on either side of the panties, complete with tantalising pink and blue fur. “These panties are so sexy… but aren’t they a little small for you? Or does mommy just have a fat pussy?”

“Rei! That’s so… th-that’s so lewd…”

“Not that I’m complaining. Look how they slip into you so easily…” Rei tugs the panties so they slip between Kaina’s chubby pussy lips, working them back and forth over her cute clit. They get wetter before her eyes, and soon Kaina’s panting, wiggling her hips with Rei’s motions. 

Rei spanks her suddenly, making Kaina yelp. “Now get these panties off,” she orders, “I wanna see mommy's pussy.” 

It’s awkward in her compromised position, but Kaina shimmies her ruined panties down her legs before nudging them aside with her toe. There’s a hole in the back of her panties for her tail, and it’s so cute helping her slide it off.

Rei has to swallow an excess of drool. Kaina’s pussy is swollen and puffy, come slicking the tight blue and purple furs. "Fuck, mommy, you've got the prettiest pussy." 

Kaina squirms with delight. "Rei!"

Rei shoves at Kaina's ass, getting her on her hands and knees on the bed and kneeling behind her. 

Rei deliberately winds Kaina’s tail around her forearm and the tip comes to rest, twitching with arousal, at the crook of her neck. Rei presses a little kiss to the tip of Kaina’s tail, smiling at the touch of the plush fur on her lips. A gratifying flush suffuses Kaina's ears.

She wraps her fist around the base of Kaina’s tail and tugs upwards, gently but insistently. Kaina arches her back, raises her ass up and presents herself fully to Rei. Her pussy lips pout open adorably, shiny with come. 

The smell of her cunt drifts up between them, making Rei’s cock painfully hard.

Rei gropes her inner thighs, stroking her thumbs over the pink and purple hairs on her outer lips. Kaina pants and trembles. She gets even wetter before Rei’s eyes, come trickling and gathering on the ridge of her clit before dripping to the bed with a sticky tap. 

“God, you’re so wet for me, mommy…”

“Just for you… Rei, you’re my good girl.”

Rei’s tail perks up and starts to wag furiously. “This good girl's gonna fuck your brains out, mommy.”

Unprompted, Kaina shoves her face into the pillow. She's gloriously face down ass up. “Oh, Rei, fuck, I can’t take it anymore! Please, please fuck me! I need your cock, mommy needs your cock, please- ”

She had only been planning to finger Kaina. It's so stupid, so utterly stupid to do this unprotected. She's sure the last thing Kaina would want is for Rei to knock her up. 

But just the thought of Kaina bearing her litter fills Rei with adoration and yearning. It's so easy to picture Kaina pregnant. Breastfeeding the cutest pups Rei's ever seen. Maybe Rei can get a taste, too… 

Rei feverishly tugs down her tights and her cock springs to its full length. The knot at its base is already plump and shiny, begging to be sheathed, and drops of precome are rolling down her shaft. 

The touch of Rei’s cock against Kaina’s dripping hole makes her jerk and gasp, shaking as if she doesn’t know whether to pull away or back up onto Rei’s cock. 

“You’re so pretty, mommy,” Rei murmurs soothingly, stroking Kaina’s back and tail, as she pushes into her in short, gentle strokes, “you’ll look even prettier on my cock. That’s my good little kitten, taking me so well…”

Even with how wet she is, Kaina’s so tight. Rei uses Kaina’s tail like a handle to pull her back onto her cock in time with each thrust. Kaina whimpers and rocks back into her, her walls clamping down on Rei’s cock. 

“Fuck, mommy, you’re so tight… so wet ,” Rei pants as she bottoms out, vision white from the pleasure of being buried to the hilt in the woman she loves, “you feel so good.”

“Ah, Rei, ah, s-so… you’re so big, I’m so full… fuck…” Kaina whines and whimpers, hitching her hips and trembling. 

Knot her, she's mine, take her knot her fill her breed her, a voice screams in Rei's head. Mine mine mine mine mine-

“Gonna knot you, mommy, gonna fill you full of my come,” Rei rants. She had wanted to be gentle, but now, with Kaina’s hot, wet walls fluttering and squeezing her length as if trying to suck her in deeper, she can’t control herself, starting to pound into her in earnest. 

“Yes yes yes oh Rei, mommy wants your knot so badly, but I… ah, I don’t think I can take it!”

Rei's heart leaps at Kaina asking for her knot… and her saying she might not be able to take it awakens something feral and base in her. 

“You don’t have a choice,” Rei growls. “You’re gonna take my knot, mommy, like it or not.” She grabs a fistful of Kaina’s glorious hair and wraps it around her wrist. She hauls back on her tail and her hair and bears down with all her weight. With a final snap of her hips and an obscene squelch, she forces her knot into Kaina. Come drips out down her cock and balls.

“Yes! Oh, Rei, yes, your knot feels so fucking good, you’re filling me so full, fuck ,” Kaina cries out, working her hips frantically. Rei ruts into her, pounding her into the mattress so hard it shakes. She’s never knotted anyone before, let alone an omega as magnificent as Kaina, and it’s ecstasy to feel it throbbing against Kaina’s walls. Every time Kaina clenches down on it she moans and bucks harder. 

“Mine! you’re all mine, mommy,” Rei growls as she floods her cunt with come. The feeling of come rushing out of her to fill Kaina up is pure bliss. She can feel it coating her walls and her own head and shaft. 

She bears down, grunts and thrusts so hard her whole body burns with the effort, fucking her come in deeper. She swears she can feel her come spilling through Kaina's cervix, and the squeaks of pain and discomfort she makes as Rei thrusts against it only make her drive in harder. 

In the haze of her orgasm she reaches underneath her to stroke Kaina's clit in time with the come spurting out of her. 

“Rei, Rei, Rei!” Kaina cries as she comes, her cunt clenching furiously on Kaina’s cock. Come spatters the sheets. 

Even after she’s come for the second time Kaina doesn’t stop pushing back into Rei. “Don’t stop, just a bit more, I need I need to come again oh Rei mommy needs it needs it needs it-" 

Rei speeds up, working her knot against that sweet spot inside Kaina as best she can and rubbing circles into her slippery clit. 

When she comes again it must be agony for Kaina, the way she writhes and keens. She’s drenched in sweat, her pretty dress plastered to her body with it, showing off every curve, every muscle. Rei’s dripping with it too, sweat flying off her with her frantic rutting. 

She’s squeezing so hard around Rei’s length, bucking and writhing so prettily on the mattress. "Oh, fuck!” Rei gasps in shock as Kaina milks another orgasm out of her. She pulses and shoots, the sounds of her thrusts getting even wetter. “Oh mommy, you're working my cock so good, oh fuck oh fuck oh fuck-

“Oh mommy, you’re taking my cock so well, you took my knot so well. You made me feel so good…” Rei's ears and tail droop even as she thrusts and pumps into Kaina. "I know how scared you are, I could smell it. I can still smell it. I know you didn't want me here… " 

"I'm sorry! I didn't mean to push you away, I didn't mean to hurt you." Kaina keeps cutting herself off with moans each time Rei pumps a last bit of come into her, and it’s so cute and endearing and sexy she thinks her heart might burst. "I care about you so much, Rei, the thought of anything happening to you is so scary."

"I just want to understand,” Rei says urgently, “I want you so bad, mommy… Kaina." 

“I love you. I love you so much, Rei!" Kaina bursts out suddenly. “I’ve loved you for so long. I’ve just been too scared to admit it.” 

Too overwhelmed with emotion to reply, Rei strokes Kaina’s back soothingly. “Kaina…” 

Finally, finally Rei's sated, and her dick starts to soften. Kaina’s tail shivers as it unwinds to droop limply next to her.

They need to have this conversation face to face, and so Rei surreptitiously tries to free herself, but she can't get her knot out. She tugs harder, but it still won't budge.

Kaina goes rigid, then starts to shake violently. She grips fistfuls of the sheets, ears flattening and tail slinking back between her legs as she tries to bolt, but she’s still stuck on Rei’s knot. 

She looks back over her shoulder with an utterly humiliated expression. She’s so vulnerable in her compromised position, face down ass up and knotted, Rei holding her by the base of her tail. There’s an agonising storm of emotions on her face: shame, exhaustion, fear, arousal, desperate hope… "I'm sorry! Damn it, I'm so stupid, I-"

“Give a girl a chance to reply, mommy… you might like what you hear.” Rei gives the base of her tail a firm tug, snugging her ass back against her hips. Kaina gives a tiny, adorable squeak, then a heated moan as Rei resettles her fully onto her knot. 

Cock still sheathed in her, she uses her grip on the base of Kaina’s tail and rolls her onto her back. She guides her tail up between them so it snugs between her breasts, and Kaina instinctively curls it tenderly around her neck. 

They’re face to face now. Kaina's vulnerable and compromised in a different way with her legs spread wide open and Rei buried inside her. She can’t avoid Rei’s eyes.

Rei nuzzles her cheek against the velvety fur of Kaina's tail, pressing another kiss to the tip.

And Kaina melts. The tentative wonder at receiving such a loving gesture is obvious from her wide, hopeful eyes and the loud purr that rumbles to life from her chest. 

It's nothing short of magical that this, of all things, should fluster her so much when she's so full of Rei's come her belly's starting to bulge. She wants to shower Kaina in such tender gestures.

Rei pets Kaina’s ears luxuriously, relishing the softness of the furs. “Because I love you, too. Probably for just as long as… as you’ve loved me.” 

Kaina's eyes widen in disbelief, then pure unadulterated joy. "You… you do?"

The fear dissolving into trust on Kaina's face is like an aphrodisiac, making Rei even hornier than she already was. She’d do anything, give everything to make Kaina happy.

"How could I not love you?" She switches her grip, tangling her fist in the hair between Kaina’s ears, making her gasp. She starts to move again, eager to show Kaina just how much she loves her, and desperate to relieve the throbbing sympathetic heat wracking her body. “Do you have any idea how long I’ve dreamed of this? Getting to make love to you in a real bed, not just eating you out in a back alley. Putting a ring on you. What our pups might look like…” 

Kaina’s face goes redder than Rei thought possible. “P-pups?” 

“Or would they be kits? Wolf kits, leopard pups, they’d be so cute, so pretty. We’d take such good care of them. You’d be such a good mom, I know it. Oh, fuck, Kaina, my cute little kitten, you’re just begging to be bred, aren’t you?”

“Yes, yes, yes , I've thought about it too, I want that so bad, god I want you to breed me-"

“Gonna breed you, wanna breed you, fuck, I…” 

She starts pumping harder, faster, desperate to give Kaina what she wants. She’s lost in a haze, unable to do anything but rut mindlessly into Kaina’s warm, wet cunt. It's already so full of her come that every thrust makes a lewd, beautiful squelch. “Wanna breed you, wanna knock you up, can I, please? Please can I breed you, my sweet little kitten?” 

Kaina blinks rapidly at Rei's hard turn into such extreme submissiveness, but goes with it, grabbing a handful of her hair and tugging in time with her thrusts. “Breed me, mommy, knock me up mommy, fuck - that's my good girl! You're fucking me so good.” 

“I’m your good girl? Really? Really?”

“My good girl, mommy, you’re my good girl! My big strong wolf, my Rei…”

Rei’s tail wags so hard it makes her hips wag too, which makes the knot wiggle inside Kaina, and they both moan. Her cunt streams around Rei's cock and her cock feels like it's bigger and harder than it’s ever been.

She fucks Kaina, works her clit, makes her come on her cock over and over and over until she's wrecked, urging Rei on and praising her, split open and panting like a dog. Rei comes till it hurts and she's totally empty.

They're a mess of come and sweat when they finally collapse, too overstimulated and exhausted to continue. Kaina’s so full of it her belly’s bulging and it's even leaking out from the tight seal of Rei’s knot. 

When she’s managed to catch her breath a little, Rei starts to pull out, worried that Kaina will be oversensitive or even hurt from how hard she was fucking her.

"No! Not yet, mommy. Wanna feel you inside me. Need your come inside me longer." Kaina clutches Rei, keeping her in their sweat drenched embrace. 

She stays gladly, and they share tender kisses.

Everything's out in the open, at long last. And Rei thinks, finally, finally, that it's time she have a pack of her very own. 

She leans down and sinks a mating bite into Kaina's neck. Kaina’s teeth in hers are just a split second behind.
