You don’t notice what you’ve done at first.
You’re still riding the reckless little high of having done something impulsive and a bit daring for a Wolf Thiren you’ve been getting frisky with for the last few weeks. Your ears are warm, your tail swaying in lazy, pleased arcs behind you as you toss your phone onto the bed and wait for a reply that you hope will be very enthusiastic.
A full minute passes. Then two.
You frown, roll onto your stomach, and grab your phone again.
Still nothing.
You open Knock Knock to double-check it actually sent—and that’s when your stomach drops so fast it feels like missing a stair in the dark.
The name at the top of the screen is not the one with the flirty nickname.
It’s Lighter.
Your roommate.
Your absurdly considerate, unfairly attractive, definitely-not-the-intended-recipient roommate, currently on duty somewhere in the city protecting an A-list celebrity as a bodyguard.
As you stare at the very risque photo you just dumped in Lighter’s Knock Knock thread, you feel your soul gently peel away from your body. Your ears slowly flatten against your hair as if trying to reduce your profile out of shame. How in the world did you tap the wrong thread?
You slam the unsend button so fast you nearly throw your phone. The message disappears, which would be great if Lighter hadn’t already seen it.
Because of course he did. He’s a professional bodyguard. He once gave you a five-minute lecture about always checking notifications immediately in case of emergencies. You literally sent it to the worst possible person if your goal was not being perceived.
Your hands start moving before your brain catches up.
Me: WRONG SEND. I AM SO SORRY.
You drop the phone onto the bed and let out a groan that vibrates through your skull.
You’ve lived together for three months. Three blissfully easy, drama-free months. Despite his rugged appearance, Lighter’s quiet, tidy, never complains about your late-night baking experiments. You cook extra portions when he works long shifts. He fixes things without being asked. The entire roommate situation has been suspiciously perfect.
And now you’ve detonated it because you were horny on a random Tuesday.
Moments later, your phone buzzes and you flinch so hard, you almost convince yourself to ignore it. But curiosity gets the better of you and you deign to take a peek.
Lighter: It’s okay. I figured it was an accident.
That somehow makes it worse.
You type immediately, trying to suppress the urge to bash your head into the wall.
Me: Please tell me you didn’t actually see it
The typing dots appear. Disappear. Appear again.
You imagine him somewhere glamorous and high-profile, surrounded by flashing lights, staring at his phone with the same quiet, unreadable expression he always wears behind his sunglasses.
Lighter: I only glanced.
Your tail curls around your waist like it’s trying to physically restrain you from spiraling into another dimension. Because that is not a denial.
That is the legal language of a man who absolutely saw everything.
You do not, as it turns out, evaporate on the spot.
Life continues with quiet cruelty, the hours slipping by whether or not you are psychologically prepared to brave the day or not. You shower. You change your sheets. You open Knock Knock, stare at the thread with the man the photo was supposed to go to, and then close the app without replying.
The thought of flirting again makes your stomach twist into knots. Whatever heat had been simmering in you has gone cold, replaced by the mortifying certainty that your very nice, very easy-to-live-with roommate has seen you in a way roommates are absolutely not supposed to.
You tell yourself you’ll explain later. Or tomorrow. Or never.
The next few days pass in a strange, fragile truce between you and your own thoughts. You move through the apartment carefully, hyper-aware of the way your clothes sit on you now that you know someone else has seen what’s underneath. You half-expect Lighter to act different, to make things awkward in some unbearable, irreversible way.
He doesn’t.
Lighter simply asks how your shifts went. He thanks you when you refill the water pitcher. He does not so much as blink in a way that might suggest he is replaying anything behind his eyes.
Which somehow makes everything worse.
By the time your next bakery shift rolls around, you are exhausted from pretending you’re not thinking about it. The early morning rush drains you physically, the scent of sugar and yeast clinging to your clothes as you lock up and step back into the late afternoon air. Your phone buzzes once in your pocket, and you ignore it without even looking.
You are not in the mood right now.
When you get home, the apartment smells like fried noodles and something spicy enough to make your eyes water pleasantly. The lights are on and your shoulders drop on instinct before you can stop yourself.
Lighter is there.
You realize belatedly that it’s his day off. He’s changed out of his usual gear and dressed down in sweats, his hair still damp like he’s just showered. Your roommate looks up from the counter when he hears the door and gives you an easy nod.
“Hey,” he greets. “You’re home late.”
“Yeah. Busy day,” you sigh.
“Figures.” Lighter nods solemnly before gesturing toward the bags on the counter. “I ordered takeout. Thought you might not feel like cooking.”
The words land gently, without expectation or any hint that this is him compensating for anything or trying to smooth over an unspoken disaster. He’s just… thoughtful. As usual.
“…You didn’t have to.”
He shrugs, a faint smile tugging at his mouth. “I wanted to. Oh, I also did the laundry this morning. It was my turn anyway, right?”
You stand there for a moment, tail flicking once behind you, unsure what to do with the gratitude swelling in your chest. “Yeah, thanks. Pretty productive day-off, huh?”
“You bet.”
Dinner unfolds quietly. You sit across from each other at the small table, trading anecdotes about how you both spent the day, your plans herewith, and nothing else in particular. Lighter listens like your words matter even when they’re mundane, and it makes the tension unspool from your shoulders.
You try to play it cool, and act like your eyes don’t catch the way he leans back in his chair, sleeves pushed up his sculpted biceps. You try to forget that you once sent him something that stripped you of all this carefully curated normalcy.
Later, when you’re alone in your room, curled on your bed with the lights off, you replay the evening in your head and feel the strange dissonance of it all. How gentle he was. How unchanged. How safe Lighter still made the apartment feel.
What you don’t know—what you couldn’t possibly know—is that your roommate is simply very good at keeping his own secrets.
Lighter is not a saint.
There are too many things stacked against that illusion—years as the head of a mercenary crew that paid for his negligence with their lives, time lost in the underground ring where survival meant learning how far a body could be pushed before it broke. Even now, with a place among the Sons of Calydon, he isn’t foolish enough to believe affiliation alone scrubs the blood from his hands.
Salvation is a generous word. At best, he has learned how to carry on knowing the others did not.
Living with you has complicated that discipline in ways Lighter did not anticipate. You were practical about it when you first offered to split rent. You made space. You trusted him with the keys to the apartment and the soft rhythm of daily life. There was no agenda in it or expectations beyond coexistence.
It was something he wouldn’t have taken for granted.
Except Lighter learned there are other kinds of sins left to him—smaller, quieter ones that leave no bruises but still manage to feel more dangerous than entering a Hollow without a Proxy.
Like doing the laundry.
Earlier today, he had decided to tackle the pile that’s been accumulating in the hamper over the last week. Lighter doesn’t mind; chores like this remind him that life can be as simple as sorting lights from darks, measuring detergent, and letting the machine hum away the hours.
He’s done this more times than he cares to count. Laundry duty rotated like everything else with the Sons of Calydon. The girls never batted an eye at handing over their delicates, and neither did he. Lighter doesn’t flush when he dumps the hamper’s contents onto the floor of the small laundry nook. He separates items methodically: Thiren-modified clothes that accommodate your tail comfortably, his own sweat-stained work clothes, a few bed linens that have seen better days.
But then there’s the something that catches his eye amid the jumble—a scrap of black lace, delicate and designed to be noticed before it’s removed. Lighter recognizes it immediately, and it hits like a delayed punch, pulling him back to that night.
He’d been on the job, while his charge was midway through her segment on a late-night talk show. Lighter had positioned himself backstage, out of the camera’s glare but close enough to intervene if needed. It was one of those idle stretches where he could let his guard drop just a fraction.
Sometime later, his phone had vibrated in his pocket. He fished it out without thinking, thumbing open the notification from you because that’s what he did, always.
The image took a while to load in the Knock Knock thread. Lighter had initially assumed this was just another baking experiment fail that you shared with him on occasion. He liked those—your whimsical messages always made his time on the clock less of a drag.
But the moment the photo showed up, his brain short-circuited.
It was you, unmistakably, captured in a mirror selfie. Your shirt was rucked up, baring the soft swell of your breasts where your pert nipples peaked in the cool air of what he now knew was your bedroom. One hand held the phone at an angle that framed everything just so, while the other tugged teasingly at the waistband of those black racy panties, pulling them low enough to hint at the curve of your hips, the shadow between your thighs.
Your ears were perked forward, tail a blurred arc in the background like it couldn’t contain your excitement, and your expression—that sly, inviting smile, eyes half-lidded with mischief—made it clear this was meant for someone who wasn’t him.
Lighter had only glanced, as he told you later. That wasn’t a lie, exactly. He’d swiped the app closed almost immediately the moment his brain processed what he was seeing. But that glance had seared itself into his memory, replaying in flashes during quiet moments: the way your skin looked under the warm light, the delicate filigree of the lace against your fingers, and the confidence in your pose that contrasted so sharply with the flustered apologies that followed.
Now, holding that same pair of panties in the laundry pile, he feels that image resurface with a vengeance.
His fingers brush the fabric, and it’s like a direct line to that mental snapshot. Heat coils low in his gut, a reminder that he’s not as detached as he’d like to pretend. He’s not embarrassed—that would imply shame, and there’s none of that here.
What he feels is worse: a sharp, aching want that he has no right to.
You’re his roommate, his friend in this fragile domestic setup. You’ve trusted him with your space, your routines, and now, unwittingly, with this glimpse of your intimacy. Seeing the crumpled lace now only amplifies the dissonance, and makes him aware of how it’s touched your skin in moments he wasn’t meant to witness.
Lighter exhales slowly, forcing his grip to loosen as he tosses the panties into the delicates bag with the rest. He tells himself it’s nothing, just fabric, just a chore. But as he starts the washer, the rhythmic churn of the machine does little to drown out the thoughts circling his mind.
He wonders if you wore them that day, if they’re carrying traces of your scent from the bakery—sugar and flour mingling with something warmer, headier. He shakes his head. This isn’t him; he doesn’t indulge in things like that. By the time you get home later, the laundry will be done. He’ll greet you, ask about your day, and keep the rest locked away where it belongs.
Lighter manages the restraint for all of five minutes after the washer kicks into its spin cycle. The delicates bag sits there on the counter, but his eyes keep drifting back to it like a magnet he can’t ignore. He tells himself to finish the chore—sort the dry load, fold everything neatly, leave your things on your bed as always. That’s the routine he’s clung to these past months.
But the tension in his body is a live wire, coiled tighter than it’s been in years. Not since the underground ring, where adrenaline and pain blurred into something primal. This is different, though—hotter, more insidious.
He fishes the black lace panties out of the bag before he can second-guess it, the fabric cool and soft against his callused fingers. It’s you invading his thoughts with that damned photo, and now this tangible reminder in his hands.
Lighter’s pulse hammers in his ears as he glances toward the apartment door down the hall, half-expecting you to burst in early from your shift. The place is silent, save for the continues whirr of the washing machine. No one’s here. No one will know.
He shouldn’t. God, he knows he shouldn’t. This is another sin to add to the ledger, smaller than blood but somehow dirtier. The Sons of Calydon preach loyalty, protection, and a code that keeps the chaos at bay. If Big Daddy or Caesar or any of them found out he was perving on his roommate like this, stealing her underwear to get off... fuck, they’d kick him out and strip him of the Champion title in a blink of an eye.
This was disgusting. Pathetic. A betrayal of the trust you’ve given him so freely.
But the ache in his cock is insistent, straining against his sweats, and the mental image of you—tits bared, fingers teasing that lace down your hips—won’t fucking leave him alone.
It’s been days of this torture, pretending normalcy while his brain replays it on loop. He needs to dispel it and purge the tension before it snaps him in half. Just this once. Then he can toss your panties in the next wash cycle, put them away, and bury this deeper than the ghosts of his past.
Lighter retreats to his room, the door clicking shut behind him with a finality that makes his stomach twist. The space is sparse but functional. Bed by the window, weights in the corner, manga volumes Caesar loaned so he “wouldn’t get bored in the city” stacked on the nightstand.
There wasn’t much room for indulgence here, usually. But as Lighter sinks onto the edge of the mattress, the panties clutched in one hand, today proves to be different from the rest. His free hand palms himself through his sweats, giving a rough squeeze that draws a low groan from his throat. He was already hard, leaking precum that darkens the fabric.
Shame burns hot in his chest, mingling with lust until it’s a toxic cocktail he can’t stop drinking. You’re so good to him—cooking extra portions for his late nights, sharing your silly baking stories, making this apartment feel like something close to home.
And here he is, defiling that with this filthy act.
He shoves his sweats down just enough to free his cock, thick and veined, throbbing in the cool air. The head is slick and flushed dark with need. Lighter wraps the lace around his shaft, the delicate fabric a stark contrast to his rough grip. It’s wrong, so fucking wrong. Yet the lace drags against his skin anyway, soft and teasing as he bites back a curse, hips bucking into his hand.
In his mind, it’s you. Not just the photo, but more—vivid, feverish fantasies he hasn’t allowed himself until now. You on your knees in this very room, vulpine ears twitching as you look up at him with that sly smile. He’d tangle his fingers in your hair, guide your mouth onto his cock, and watch those lips stretch around him.
“Fuck,” he mutters raggedly, pumping faster. The lace catches on the ridges as it sends sparks up his spine. He’d be gentle at first—always gentle with you—but then you’d moan, and he’d lose it, thrusting deeper, feeling your throat tighten around him.
Or he could have you bent over the kitchen counter, where you bake those late-night treats. He’d hike up your skirt, yank these same panties aside and bury himself inside you. Your tail would thrash, brushing his thighs as he pounds into you, one hand on your hip, the other reaching around to pinch those pert nipples until you cry out. Sugar and yeast would cling to your skin, mixing with your sweat, and he’d lick it off your neck before biting down just hard enough to mark.
It’s disgusting. He’s disgusting. A protector turned predator in his own head, and the shame of it makes his balls tighten, the orgasm building fast and relentless. His strokes turn sloppy, the lace abrading his skin just enough to hurt, a punishment he deserves. Lighter thinks of your face in that photo and twists it, imagines you whispering his name instead of whoever it was meant for.
Lighter... please...
That’s what breaks him. A guttural moan rips from his chest as he comes, hot spurts coating the lace, soaking through the delicate threads. His vision blurs and his body shudders with the cresting release. Finallly, the tension embedded in his bones uncoils in waves that leave him breathless and hollow.
For a long moment, Lighter sits there with his cock softening in his hand, the ruined panties a sticky mess. Reality crashes back in, prompted by the continuous ringing of the washer down the hall letting him know the cycle’s done. Shame floods him full throttle now.
What the fuck has he done?
He cleans up quickly rinses the lace in the sink, scrubs until there’s no trace left, then tosses it back into the delicates bag like nothing happened. By the time this next load finishes, he’ll fold it all, place your things on your bed, and greet you with that same nod when you get home.
But unlike laundry, this secret is a stain he can’t wash out.
You’ve been feeling off for a week now.
At first, you tell yourself it’s nothing. Just one of those days where you wake up irritated with no clear cause, your tail flicking against the mattress like it’s got a mind of its own, and your ears twitching at every small sound.
By midday, you can’t stay still for long. Standing feels wrong. Sitting feels worse. Even familiar routines itch under your skin.
The bakery has been busy lately—too many early mornings with the constant warmth of ovens pressing in from all sides. By the time you’re halfway through your shift, sweat beads along your spine despite the cool room, and there’s a faint, uncomfortable heat pooling low in your body.
It’s distracting. Enough that you fumble an order you’ve made a hundred times before.
“Hey,” your boss says gently, appearing at your side. She’s a Rabbit Thiren with long, fluffy ears and sharp eyes, and she’s been doing this long enough to notice things others miss. “You alright?”
You open your mouth to answer and sway instead.
“Whoa—easy.” Her nose twitches as she steadies you, eyes lingering on your form for a beat longer than necessary. The look on her face then shifts from concern to something more knowing.
“…Have you been feeling feverish?”
“Just tired, I think,” you admit. “My sleep quality’s shit lately.”
She hums softly. “When was the last time you tracked… you know. Your cycle.”
Your stomach sinks.
“Oh.”
Her ears twitch. “You might be coming into heat. I can smell the beginnings already.”
Thank god the afternoon rush has already come and gone because that explains too much, all at once. The restlessness. The heat under your skin. The way your thoughts keep circling the same empty spaces without landing anywhere solid. You do the math quickly in your head and grimace.
“It should be around now,” you mutter. “I just—forgot, I guess.”
Your boss winces in sympathy. “That’ll do it. Especially if you haven’t been using suppressants yet. Pre-heat sickness can be rough.”
You sigh, disgruntled more than embarrassed. Of all the times to lose track of it…
“Yeah. Guess that explains why I feel like garbage.”
“No shame in it,” she reassures, already waving you toward the back. “Go home early. Get what you need. You don’t want this sneaking up on you while you’re stuck on your feet all day.”
You hesitate, pride flaring briefly before the lightheadedness makes the decision for you.
“Thanks,” you murmur.
When you step outside, the air feels cooler but sharper, every sensation turned up just a notch too high. By the time you’ve bought the necessary supplies and make it home, you’re fully aware of your own body in a way you haven’t been in months.
That’s right. This was why you’d been trying to get with that Wolf Thiren a month ago. Why you’d felt confident enough to send something reckless to keep his attention just long enough to bridge the gap to your next heat. You’d always been good at planning ahead.
Except your plans hadn’t just fallen apart.
They’d detonated—right into your roommate’s inbox.
And now you were going to endure this heat miserable and alone, because seduction required a clarity of mind you no longer possessed. You’d been so distracted by the fallout of sending Lighter that photo that you’d forgotten the most basic contingency: surviving the season at all.
You get home and prepare like this is a siege.
Water bottles lined up within arm’s reach. Easy food that won’t turn your stomach. Cooling packs shoved into the freezer just in case. You were also stocked up heavily on lube and batteries for any… toys you’ll need to use. You inventory everything twice, because this is the one situation where overpreparing actually feels sane.
At least you won’t be caught off guard.
Lighter, mercifully, is away for a few days. His client’s press tour has dragged him out of the city, which means the apartment is yours alone for now. You don’t know if your heat will be finished by the time he returns, but you cling to the hope anyway. It’s easier to endure discomfort than the thought of navigating this with your roommate present, no matter how unflappable he is.
You change into the lightest clothes you own: a loose tank, cotton shorts that won’t trap heat. Your tail swishes irritably as you crawl into bed, curling on your side like some half-feral creature trying to ride out an illness. The room is dim, curtains drawn, the quiet punctuated only by the distant hum of city traffic.
Your phone buzzes.
You groan, half-expecting it to be another message you don’t have the energy to deal with—but when you check, it’s actually your roommate himself .
Lighter: Blazewood is exactly as thrilling as you’d expect.
Lighter: Which is to say, not at all.
You huff a small laugh despite yourself and type back.
Me: Aren’t you from Blazewood though?
Lighter: Exactly why I feel qualified to complain about it.
You smile at the screen. The conversation drifts easily after that—him complaining about how living in the city has made him unused to the desert heat, you responding with dry sympathy and a few jokes about him missing decent takeout.
You set the phone down eventually, still smiling faintly, and stare up at the ceiling. Whatever comes next, you’re oddly grateful for this small normalcy. For the quiet proof that you and Lighter have, somehow, moved past The Incident.
At least on the surface.
You roll onto your side and let yourself rest—hoping, perhaps foolishly, that when he comes home, this will all already be behind you.
Except it’s not as easy as you’d hoped.
You wake up tangled in your sheets, disoriented enough that for a moment you don’t know where you are or how long you’ve been there. The dim glow of your nightstand clock blinks accusingly—12:03 AM. Midnight.
Grogginess clouds your thoughts as you fumble for your phone, the screen’s light stabbing at your eyes. No missed alarms? You swear you’d set one for dinner time—to take the suppressant before things escalated. But the hours must have slipped away in that uneasy nap, your body betraying you by crashing hard after the pre-heat haze.
Now it’s too late; suppressants are preventive, not curative. Taking one mid-surge would only make the symptoms worse. You’re committed now, stuck riding this out the old-fashioned way.
A low whine escapes your throat as you shift, the movement sending a fresh gush of slick between your thighs. Your pussy throbs with an insistent, painful emptiness, clit swollen and hypersensitive even without touch.
It’s been years since you’ve gone through a heat solo and you’ve forgotten just how brutal it is. The restlessness from earlier has amplified into agony. Your tail lashes against the mattress, ears pinned flat against your head as sweat trickles down your neck. Every breath feels too hot, too shallow, your body screaming for relief that fingers alone won’t provide.
Shakily, you reach for the drawer of your nightstand to pull out a vibrator. One of the stronger ones, ridged and curved for that extra edge. You peel off your soiled shorts and underwear with a hiss, the cool air hitting your slick folds like a tease that only heightens the ache. Slick coats your inner thighs, proof of how far gone you are. You switch the toy on, the low buzz cutting through the silence, and press it directly to your clit.
The vibration hits like lightning, ripping a gasp from your lips as your hips buck involuntarily.
It’s intense, almost too much at first, but the pain of need overrides any overstimulation. You circle the tip around your clit, chasing that sweet spot, your free hand fisting the sheets as waves of pleasure-pain crash over you.
Your body arches as you grind against the toy. It’s mechanical, desperate; you come fast and hard in a shuddering release that floods you with temporary bliss, slick spilling anew as your walls clench around nothing.
But it’s not enough.
Heats like this demand more. Solo play is a bandage on a gaping wound, providing spurts of relief but no true satisfaction. As you catch your breath in the dark, your mind starts to wander, filling the void with hazy fantasies to push you toward the next orgasm.
At first, it’s generic—a faceless, broad-shouldered Thiren your biology craves. You’d imagine him pinning you down, his knot swelling to lock inside you, filling that aching emptiness until you’re mindless and sated. But the image shifts unbidden, the features sharpening into something familiar.
Dark teal hair, tousled from a long day. A lopsided smile that quirks just so, the one he gives when he’s teasing about your baking disasters or thanking you for dinner.
Lighter.
God, no—your brain stutters, but the thought sticks, heat flushing your cheeks even as your body responds. You press the vibrator harder against your clit, dipping the tip lower to tease your entrance, imagining it’s his fingers instead.
Broad, callused from years of fighting, sliding into you with that quiet confidence he carries everywhere. He’d be gentle but firm, stretching you open while his other hand strokes your tail, your ears, murmuring in that gravelly voice.
“Easy,” he’d say, like he does when he steadies you after a long shift. But then he’d see how wet you are, how desperately you need it, and that restraint would crack.
You whimper, thighs trembling as you fuck yourself with the toy now, thrusting it in shallowly while the vibrations buzz against your clit. In your mind, Lighter hovers over you with his sweat-damp hair falling into his eyes, that lopsided grin turning hungry as he sinks into you.
No knot, but fuck, he’d make up for it with stamina, pounding into you deep and relentless, one hand on your hip to hold you in place while the other teases your nipples. Your tail would wrap around his waist, pulling him closer, and he’d groan your name, burying his face in your neck to breathe you in.
A pang of guilt flickers at the edges of your thoughts, but it’s drowned out by your building release. It’s wrong—he’s your roommate, your friend—but that only makes it spurs you on. You come again with a cry, back arching off the bed, the toy buried deep as your walls flutter around it.
The room spins gently, a post-climax dizziness that leaves you boneless and temporarily sated. You slump back against the pillows, your vibrator discarded beside you on the damp sheets. It’s a fragile peace, one you know won’t last, but for now, you savor it as you reach for a water bottle.
The cool liquid slides down your throat, quenching a thirst you hadn’t fully registered. You drink greedily, half the bottle gone before you set it down and wipe your mouth with the back of your hand.
But as the hydration hits your system, your baser instincts begin to stir awake. The emptiness returns, manifesting as a deep, gnawing yearning not just for physical release, but for connection. For a mate’s presence, their scent wrapping around you, grounding you in the chaos of your cycle.
Logically, you know you don’t have one, but your body rebels against the thought, hormones flooding your veins with irrational insistence. You need it. Need him. Someone. Anyone.
No—not anyone.
Your tail flicks restlessly as you slide out of bed on unsteady legs, slick trickling down your thighs in a fresh wave that makes you whimper. You’re naked from the waist down, tank top clinging to your sweat-slicked skin, but modesty doesn’t register in this heat-addled state.
Disorientation clouds everything; the apartment feels too big, too empty. Sounds are muffled, like cotton in your ears, and your phone buzzes insistently on the nightstand.
The caller ID flashes with Lighter’s name across the screen.
But you don’t notice, too lost in the primal pull guiding you toward the hallway.
You trudge toward his room on autopilot, frowning when you try the knob and it twists all the way. Why would his door be unlocked? He must have forgotten in the rush of packing for the trip, or maybe it’s just habit—trusting you as much as you trust him. Either way, it’s ajar just enough for you to nudge it open with your shoulder, and the moment you cross the threshold, his scent hits you like a tidal wave.
Spicy and musky, like smoked cedar mingled with desert sand and a hint of leather from his gear. It’s the scent of safety, of quiet evenings sharing takeout and late-night fixes around the apartment.
Your legs buckle beneath you, knees weakening as a gush of slick floods your core. A needy whine escapes your lips, ears flattening as you stagger forward, inhaling deeply. It’s comforting, wrapping around your frayed nerves like a balm, but it only amplifies the ache, turning satisfaction into torment once more.
The room is dim, lit only by the faint glow of city lights filtering through the blinds, but your enhanced senses pick out details: the sparse furniture, weights in the corner, books on the nightstand. And there, on the neatly made bed is a stack of folded clothes.
You don’t think; you just act, crawling onto the mattress and curling into the pile. A soft shirt, sweats, maybe a hoodie. Whatever it is, you bury your face in them, breathing him in deeply.
Lighter’s scent envelops you like a security blanket, making you feel protected even in his absence. Your tail curls around the bundle, hugging it to your chest as you nuzzle deeper. A contented purr rumbles in your throat despite the lingering need. You’ve forgotten all about the toys back in your room, mind too fogged to care.
Your fingers find your slick folds easily, parting them with a gasp as you circle your clit, the touch electric in the haze of his aroma. It’s sloppy; dipping two fingers inside yourself, thrusting shallowly while your thumb rubs frantic circles above.
Slick coats your hand, the wet sounds obscene in the quiet room, but all you can focus on is Lighter: how safe he makes you feel, how even just the ghost of his presence chases away the isolation of your raging heat.
Your eyes are squeezed shut so tightly that white sparks dance behind your lids. The fantasy has solidified now: Lighter above you gazing at your poor form with eyes half-lidded, that deep voice murmuring your name as his hips roll in the same rhythm as your fingers. You can almost feel the weight of him pinning you to the mattress, the heat of his breath against your ear.
A broken sound escapes you when the pleasure starts to crest again. But then you hear it.
The sound of your name.
For one disoriented heartbeat you think it’s part of the fantasy, another cruel trick of your heat-drunk brain. But the voice comes again, laced with something that sounds dangerously close to shock.
“…hey.”
You freeze.
Your fingers are still buried inside you. Your tail is still wrapped tight around the bundle of his clothes. Your face is still pressed into the soft cotton of his shirt, nose buried in the collar where his scent is strongest.
And Lighter is standing in the open doorway of his own bedroom.
He hasn’t moved past the threshold. Leather jacket still zipped, duffel slung over one shoulder, sunglasses perched on his nose even in the middle of the night. The faint glow from the hallway spills around him, turning his silhouette into something almost unreal.
His eyes—visible now that he’s slowly, carefully pushing the sunglasses up into his hair—are wide. There is no disgust in there, but there was confusion. His gaze locks on you like he’s forgotten how blinking works.
You should scream. You should scramble off the bed, yank the sheets over yourself, stammer apologies until your voice gives out. But your body refuses to obey. The heat has you pinned in place, slick still leaking around your fingers, clit throbbing with the orgasm that was so close a second ago.
You can’t even pull your hand free. The humiliation is there—searing, and white-hot—but it’s tangled up with the scent of him, the reality of him, and your traitorous cunt clenches hard around your fingers at the sight.
“Lighter,” you bleat. “You’re… you’re supposed to be at work.”
He exhales through his nose, a short, unsteady sound.
“Client’s press junket got pushed up, so we wrapped up early. I texted. Even called you. Twice.” His voice comes out carefully, like he’s talking someone down from a ledge. “You didn’t answer.”
And now he is presented with the reason why.
Another wave of slick drips down your thigh. You whimper and his gaze flicks down, then back up to your face so fast it’s almost comical if the situation weren’t so mortifying.
The door clicks shut behind him, soft but final.
“You’re in heat,” Lighter says. Not a question. A statement. “Why didn’t you tell me?”
You nod jerkily. Tears prick at the corners of your eyes—not from sadness, but from the overwhelming collision of need and embarrassment. How could you ever begin to explain this?
“I forgot it was going to hit today…. I didn’t mean to—” Your voice cracks. “I just… needed… your scent. I’m sorry. I’m so sorry.”
He doesn’t answer right away.
Instead Lighter drops the duffel to the floor with a muted thud. Then, slowly, he shrugs out of the leather jacket and drapes it over the back of the desk chair. The movement is deliberate, almost gentle, like he’s trying not to spook you.
“You don’t need to apologize.” His voice is rougher now, frayed at the edges. “Not for this.”
You swallow hard. “I’m on your bed. With your clothes. Touching myself. That’s—”
“Instinct,” he cuts in quietly. “You’re not thinking straight. I’m pretty sure heats make you do that. We have a Cat Thiren back at HQ, you know.”
He takes another step closer. Close enough that you can see the way his throat works when he swallows. He’s trying to stay calm. You can smell it—his own arousal spiking beneath the careful control, sharp and smoky.
Your fingers twitch inside you, and a fresh whimper slips out.
Lighter’s jaw clenches.
“Tell me to leave,” he murmurs. “Say the word and I’ll go crash on the couch. Lock the door behind me. You won’t see me until morning.”
Your heart hammers so hard you’re sure he can hear it.
But the thought of him walking away—of losing his scent, his presence, the only thing that’s made the last hour bearable—feels worse than the heat itself.
You shake your head with a whine.
“Don’t,” you breathe. “Please don’t go.”
Something flickers across his face. Relief, maybe, or hunger, or both.
He crosses the last few steps to the edge of the bed in silence. He doesn’t touch you just yet. But he looks down at you with those steady eyes, taking in the mess you’ve made of yourself on his sheets.
Then, very slowly, he reaches out.
His knuckles brush your ankle, the leather a foreign yet sweet sensation against your skin. You shiver hard, thighs falling open another fraction without conscious thought.
“Tell me what you need,” he pleads, and his eyes are so earnest, you can’t help but answer.
“You. Just… you.”
Lighter exhales, long and ragged, like he’s been holding his breath for years.
Then he leans down, plants one knee on the mattress, and removes his gloves.
Moments later, his knuckles linger against your ankle for one more heartbeat—giving you every last second to pull back—then his hand slides higher, that warm palm smoothing up the trembling length of your calf. He moves like he’s handling something fragile and explosive all at once.
“Still with me?”
You nod frantically, ears twitching, tail lashing once against the sheets before curling tight around his wrist like it’s trying to anchor him there.
Lighter lets out another long breath before settling fully onto the edge of the bed. The mattress dips under his weight. He doesn’t crowd you—he kneels between your spread thighs instead, broad shoulders blocking out the faint hallway light, leaving you both in soft shadow.
His fingers—those big, scarred, calloused ones you’ve watched fix cabinet hinges and stir soup without thinking—hover just above your slick-soaked folds.
“Look at me,” he says quietly.
You do. His eyes are dark, pupils blown, but the expression behind them is steady. Kind. The same look he gives you when you burn toast at 2 a.m. and he wordlessly scrapes it into the trash for you.
“You don’t have to do anything you don’t want,” he tells you. “We stop the second you say. Even if it’s just ‘stop’. Even if it’s just a look. Okay?”
Your throat works. “Okay.”
He nods once. Then, finally, he touches you.
Two fingers glide through your folds, gathering slick without pressing inside. You jolt anyway, a sharp whine punching out of you before Lighter shushes you gently. His free hand settles on your thigh, thumb stroking soothing arcs over the sensitive skin.
“Easy, sweetheart. I’ve got you.”
The endearment hits like a spark. You’ve never heard him say anything like it before—not to you, not to anyone—and it makes your cunt clench hard around nothing. More slick spills out; he groans under his breath when he feels it.
“Fuck, you’re so wet,” he mutters. “That’s it. Let it happen. You’re doing so good already.”
He circles your clit with the pads of his fingers—light at first, then firmer when your hips buck up into his hand. You’re already so close from earlier that it doesn’t take long. Your thighs tremble, nails digging into the sheets.
“Lighter—please—”
“I know, baby. I know.” His voice stays calm, even as his breathing gets rougher. “Come for me. Let me feel it.”
You do. You shatter with a choked cry, walls fluttering around nothing while his fingers keep rubbing slow, steady circles through the aftershocks. He doesn’t stop until you’re whimpering from overstimulation, hips twitching away and then back again in confused need.
When the tremors of your body subside, he leans down and presses the softest kiss to the inside of your knee. “Good girl,” he whispers against your skin. “So fucking good.”
The praise sinks into you like warm honey. You’re still mortified that he walked in on you like this, dripping all over his bed and scent-marking his clothes like some desperate animal. But every time the shame tries to rise, he does something gentle—strokes your tail, murmurs reassurances, looks at you like you’re the only thing in the world that matters—and it melts away again.
He keeps touching you slowly and patiently. Two fingers sliding inside once more, curling just right, thumb brushing your clit in lazy figure-eights. You’re sensitive, overshot, but the heat won’t let you stop. You need more. Always more.
Lighter is more than aware.
“You want my fingers deeper?” he asks, voice dropping into something silkier. “Want me to fuck you open nice and slow until you can take three?”
You whimper, nodding as your hips rock down to meet his hand.
“Words, sweetheart.”
“Y-yes, please. Deeper—”
He obliges. Another finger slides in, stretching you carefully, scissoring just enough to make you see stars. His free hand pets your ears, scratches lightly behind them until you’re purring through the moans.
“That’s it,” he murmurs. “Look at you, taking me so well. Bet you’d look even prettier stretched around my cock, huh? All full and needy and dripping for me.”
The filthy words make your brain short-circuit. Your cunt clenches hard around his fingers, and he groans like his restraint is hanging on by a thread.
“Fuck, you like that. Don’t you?”
You’re beyond shame now. “Yes… Yes. Need it…”
“Need what?” he coaxes, thumb pressing harder on your clit. “Tell me exactly.”
Your voice cracks. “Your cock. Inside me. Please. I can’t… I need you—”
For the first time since he walked in, something flickers across his face—real conflict. His jaw ticks, eyes searching yours like he’s looking for any sign of hesitation, any sign that the heat is speaking for you instead of you speaking through it.
“You sure?” he asks quietly. “This isn’t just the heat talking?”
You don’t answer with words.
Instead you surge up, fingers tangling in the short hairs at the nape of his neck, and yank him down.
Your mouths crash together; messy, desperate. You taste salt and smoke and him, and it’s better than any fantasy. Lighter groans into your mouth as his restraint finally starts to fracture. His fingers slip out of you; you whine at the loss, but then his hands are everywhere—gripping your hips, sliding under your tank top to palm your breasts, thumbs brushing over hard nipples.
He kisses like he fights: controlled until he isn’t. Then it’s filthy—open-mouthed, licking into you, sucking on your tongue until you’re trembling again. You bite his bottom lip; he growls, hips jerking forward so you can feel how hard he is through his pants.
When you finally break apart, both of you are panting.
“Fuck,” he rasps, forehead pressed to yours. “Are you really sure?”
Even through the haze of arousal, his discretion makes your heart flutter. But instead of answering, you tug harder on his hair, dragging his mouth back to yours for one more bruising kiss before you whisper against his lips:
“Take your clothes off. Now.”
That’s what finally breaks him.
Lighter tosses his sunglasses onto the nightstand and pulls back just enough to yank his shirt over his head—muscles flexing, a collection of scars catching the dim light. He shoves his pants and boxers down in the same impatient sweep. His cock springs free moments later, thick and flushed and already leaking at the tip. You stare as your cunt throbs with fresh need.
Lighter settles back between your thighs, one hand braced beside your head, the other guiding himself to your entrance. He notches the fleshy tip against you and pauses.
“Last chance,” he chuckles, but there’s little mirth in it. “Tell me no and we stop.”
You wrap your legs around his waist and pull him closer.
“Don’t you dare stop,” you breathe.
He exhales a shaky laugh—half relief, half surrender.
Then he pushes in.
He sinks in agonizingly slow like he’s savoring every flutter of your walls as they stretch to take him. The head of his cock pops past the tight ring of muscle and then it’s just heat, pressure, fullness, until his hips finally press flush to yours and he’s buried to the hilt. The size of him overwhelming you so much that if not for your heat-laden slick, you would’ve struggled.
You choke on a sound that’s equal parts a sob and a moan. Your nails dig into his shoulders; your tail lashes wildly before coiling around his waist like it’s trying to keep him exactly where he is. He’s so deep you swear you can feel him in your guts.
Lighter stills, breathing hard through his nose, forehead pressed to yours. His hands bracket your head, thumbs stroking along the base of your twitching ears in slow, soothing circles.
“Still with me, sweetheart?” he rasps. His voice is wrecked, but the gentleness is still there.
You nod frantically, tears leaking from the corners of your eyes. Not from pain. From relief. From finally having something—someone—to fill the screaming void that’s been clawing at you for hours.
“Words,” he murmurs, brushing his lips over your damp cheek. “Need to hear you.”
“Y-yes,” you gasp. “Please—move. Please move, Lighter, I can’t—”
He kisses you then, a soft press of his lips that makes you purr. But then he takes it deeper. Hungrier. His tongue slides against yours in lazy strokes while his hips give the smallest experimental roll.
You keen into his mouth.
That’s all the permission he needs.
Lighter pulls out halfway then snaps back in with a wet, filthy sound that makes your whole body jolt. Every thrust dragging against every sensitive spot inside you until your vision whites out at the edges.
But he doesn’t stop there.
His hands are everywhere. One palms your breast, thumb flicking over your nipple in time with his hips. The other slides down your side, grips your hip, then slips under to cup the curve of your ass—lifting you just enough to change the angle so he hits deeper, harder. His calloused fingers knead the base of your tail until you’re arching, purring brokenly against his throat.
Lighter kisses your neck. Your jaw. The sensitive spot behind your ear that makes your toes curl. When he nips lightly at the shell of your ear you whine so loud it echoes off the walls.
“Fuck, listen to you,” he groans against your skin. “So pretty when you’re falling apart for me.”
He shifts—hooks one of your legs higher over his hip, opening you wider—and the next thrust punches a scream out of you. The headboard starts to knock against the wall in steady rhythm.
You’re drooling now; dazed with spit slicking the corner of your lips. Every thrust drives another helpless sound from your throat. Your nails rake down his back and he hisses witch each pass, but it only makes him fuck you harder.
“That’s it,” he pants, low and filthy-sweet. “Let it out, baby. Let me hear how good it feels. You’re taking me so fucking well—look at you, all messy and needy just for me.”
You try to answer but all that comes out is a garbled moan. Your cunt clenches hard around him; he curses under his breath, hips stuttering for a second before he finds the rhythm again. He moves like he’s trying to imprint himself inside you, and you’ll gladly let him leave his mark.
Lighter’s laces your fingers together, and pins it above your head. The other slides between your bodies, calloused thumb finding your clit and rubbing tight, relentless circles. The dual sensation—his cock splitting you open, his thumb working your swollen clit—snaps something inside you.
You come so hard your vision blacks out for a second. Walls spasming, gushing slick around him, soaking the sheets, his thighs, everything. Your whole body seizes and your back bows off the bed as a broken cry ripping from your throat.
Lighter doesn’t stop.
He fucks you through it—slows just enough to drag it out, to make every aftershock feel like another peak. His mouth finds yours again, swallowing your whimpers, kissing you sloppy and deep while he murmurs praise against your lips.
“Good girl. So fucking good. Coming so pretty around my cock—gonna make you do it again, yeah? Gonna keep fucking this sweet little cunt until you can’t think straight.”
You’re a drooling, trembling mess beneath him. Tears streak down your cheeks; he kisses them away without breaking rhythm.
“Again,” he growls softly. “Come on, sweetheart. Give me another one. I know you’ve got more in you.”
His hips snap harder, the wet slap of skin on skin obscene in the quiet room.
“Lighter. Lighter, please—too much. Don’t stop—don’t stop—”
“Never,” he promises, his breath hot against your throat.
Lighter angles his hips just right—hits that spot again—and you shatter a second time, harder than the first. Your scream muffles against his shoulder as you bite down, nails sinking into his back, cunt milking him in frantic pulses.
He breathes out a broken moan of his own and finally lets himself go.
His rhythm stutters. Hips slamming once, twice, then burying deep as he comes with a ragged curse, spilling hot and thick inside you. You feel every pulse and it drags your own orgasm out longer until you’re both shaking, panting, clinging to each other like the world might end if you let go.
Lighter doesn’t pull out right away.
Instead he stays buried, softening slowly as he presses lazy kisses to your damp forehead, your cheeks, the tip of your nose. His hands stroke down your sides soothingly before petting your ears and tail until your trembling eases into boneless exhaustion.
“You okay?” he whispers hoarsely.
You manage a tiny, wrecked nod. Then, barely audible:
“…stay inside. Please.”
He exhales a soft laugh against your hair.
“Wasn’t planning on going anywhere,” he murmurs.
He shifts carefully, rolling you both so you’re tucked against his chest, still connected, his arms wrapped around you like he’s shielding you from the rest of the world.
The heat still simmers under your skin.
But for the first time in hours, it doesn’t feel like torture.
It feels like coming home.
Sunlight filters through the half-closed blinds in thin, golden slats, painting stripes across the rumpled sheets and the two bodies still tangled in them.
You wake slowly—lucid for the first time in what feels like forever.
The heat is still there, but it’s no longer a screaming inferno. Your body feels heavy, pleasantly sore, every muscle singing with the memory of last night. You can breathe without wanting to claw something apart. You can think.
And the first coherent thought that hits you is: oh god.
Lighter is asleep beside you, face half-buried in the pillow, one arm slung possessively across your waist. His dark teal hair is a disaster and there are fresh marks blooming across his throat and shoulders: your bite marks, red-purple lovebites, long parallel scratches down his back where your claws had dug in when he’d fucked you through your third (fourth?) orgasm. You can feel the mirror image on your own body—his teeth on your neck, your collarbone, the faint imprint of his fingers bruised into your hips and thighs.
You stare at the ceiling for a long second, mortification rising like steam.
You need to get out of here before he wakes up. Before you have to look him in the eye and remember how you begged for his cock, how you sobbed his name. You start to inch toward the edge of the mattress, trying not to jostle him. One foot touches the floor—
A large hand shoots out, snags your wrist, and yanks.
You squeak as the world flips. One second you’re sitting up; the next you’re flat on your back again, Lighter looms over you, knees bracketing your hips, forearms braced on either side of your head. His eyes are still heavy-lidded with sleep, but they’re focused enough and there’s a tiny, crooked smile tugging at the corner of his mouth.
“Going somewhere?” he asks, voice rough from disuse.
Your ears flatten. Your face burns so hot you’re sure it’s visible from orbit.
“I—um. Bathroom. Water. Normal things.”
“Uh-huh.” He doesn’t budge an inch. “You’re cute when you’re panicking.”
“I’m not panicking,” you mutter, even as your tail curls nervously around his thigh. “I’m… strategically retreating.”
He huffs a soft, fond laugh and the sound does dangerous things to your already fragile composure.
Then he sobers.
“Hey,” Lighter says gently. “We should talk. Before the next wave hits.”
You swallow before nodding along.
He shifts his weight, settling more comfortably between your legs. Just close enough that you can feel his warmth, smell that familiar mix of smoked cedar and leather and now, unmistakably, you.
“So,” he starts. “The photo from back then.”
You wince. “Yeah. About that. It… wasn’t meant for you.”
“I think we both know that already.” He traces a thumb along the edge of one of the bites on your shoulder. “Who was it for? If you don’t mind me asking.”
You exhale through your nose. “Some Wolf Thiren I met a couple months back. Thought he’d be… convenient. For this.” You gesture vaguely at your own body. “I was trying to line up a heat partner. Got cocky. Sent it to the wrong thread. And then the heat hit early and I forgot every contingency plan I ever had because I was too busy being mortified that you saw my tits.”
He breathes out a quiet laugh.
“Understandable.”
You blink. “That’s it? No… judgment? No ‘what the hell were you thinking’?”
He shrugs. “You’re an adult. You were trying to take care of yourself. Heat’s rough enough without adding shame on top of it.” His thumb brushes over the bruise on your hip. “And in the end… you got a mate, right?”
Your brain short-circuits.
“M-mate?” you sputter. Your ears flick straight up, then pin back again. “I—I mean… technically? Maybe? But you don’t have to—”
He raises one brow. “You kept moaning it last night. ‘Mate.’ ‘My mate.’ ‘Please, Lighter, my mate—’”
You slap both hands over your face with a muffled scream.
“Oh my god. Kill me now.”
He smiles before peeling your hands away so he can look at you. His expression is soft in a way you’ve never seen before.
“I’m not complaining,” he says. “I liked hearing it.”
You peek at him through your fingers. “…You did?”
“Yeah.” Lighter leans down, presses a slow, deliberate kiss to the corner of your mouth. “A lot.”
Your heart does something ridiculous in your chest.
He pulls back just enough to meet your eyes again. “So. How long do I have to file for leave?”
You blink. “What?”
“Well obviously I can’t let you deal with this alone now.” He says it like it’s the most obvious thing in the world. “I’m your mate, right?”
You open your mouth. Close it. Open it again.
“Why do you keep saying that!!!”
“Because I’m your mate,” he deadpans.
You make a strangled noise and bury your face in his chest. He laughs again and wraps both arms around you, rolling so you’re tucked against him instead.
When your mortification finally eases enough to speak, your voice is small.
“…Thank you. For not making this weird. For… everything.”
He hums, fingers carding gently through your hair, scratching lightly behind your ears until you melt against him.
“No problem,” he murmurs. “But I want you to know—I don’t do this with just anyone.”
You lift your head, look at him.
“Neither do I,” you admit.
His expression softens even further—if that’s possible—as he presses another kiss to your forehead.
“Good. We’ll sit down and talk it through properly once your heat’s passed,” he adds. “Figure out what this means. No pressure. No rush.”
You nod, throat tight with an emotion you can’t quite name.
“But for now,” he continues, voice dropping into something warmer, “we should probably shower. Eat real food. You’ve been running on snacks and orgasms for twelve hours.”
You snort despite yourself. “Romantic.”
“I try.” He grins and rolls off you, offering a hand. “Come on, mate. Up.”
You take his hand.
And when he pulls you to your feet, steadying you when your legs wobble, you think maybe this unexpected heat might turn out to be the best thing that’s ever happened to you.
(And yeah. The shower is definitely not just a shower.)
(But that’s a story for after breakfast.)
