Light is filtering from under Kili's bedroom door. He doesn't remember lighting a candle before he went out hunting, and surely it shouldn't be able to burn for so long. He is so very tired and as the first snows are starting to fall on Erebor, his hunting trip was cold, long. And all Kili wants right now is his bed and maybe to take a bite out of the rations he carried with him on his trip in lieu of a proper dinner. It didn't take much time for him to let himself in, only to find Fili coming out of his bathroom (when he has his own!), freshly cleaned up, his hair dripping on the tiled floor. Yet Kili's exasperation upon seeing the blond using his quarters as his own suite doesn't last long, as a smile creeps up his face and he goes to hug his brother.
"You came back from your trip to the Iron Hills!" Kili exclaims, releasing a bit of his embrace around Fili's back, he adds "Why didn't you send me a letter when you left! I thought that all this boring diplomatic talk killed you!" Fili's booming laugh warms Kili's body in a way he didn't know he'd missed, his brother's hands coming to squish his face.
"That nearly killed me! That's for sure! I missed Erebor so much, you have no idea!" Fili cries, and finally releases his little brother's face. He goes to lay on Kili's day bed, decorated with various cushions and soft furs, overlooked by a huge silver mirror. "You should get changed, you smell like a wet dog!" Fili laughs, "Did you hunt anything good?". He was making himself at home more than he already was, taking a book from the table adjacent to the bed and burying himself under what looks like a wolf's pelt.
"Pfft! I'm sure you smelled just as bad when you came back from your trip! Like a wet pony I bet!" Kili says as he throws his cape on a chair. He keeps on undressing as he continues "And no I didn't catch anything good." Kili adds, his face probably turning sour. He usually isn't as bothered by it when he's hunting with members of Company or other friends. But at the end of autumn, every hunt counts, and winters aren't easy in the Lonely Mountain. "Did you have dinner yet?"
Fili looks at him with a puzzled expression, then goes back to reading "I'll go grab something in the kitchens while you bathe!" he says without looking away from his book.

Kili is drawn out of his bath by the sound of the door closing, followed by the delicious smell of what he recognizes as Bombur's goat stew. Fili has set the tray on a small table near the day bed, handing a bowl filled to the brim to his brother as soon as he sits down. "I bet you missed that", Kili says with a smile, his brother answers by shoveling another big spoonful of goat meat in his mouth, then chasing it down with a swing of ale he brought back from the kitchen alongside their dinner. "Stop staring at me and eat!" Fili pushes him a bit with his shoulder. They're sitting side by side on the day bed, huddled under a fur pelt, from their knees up to their shoulders they're touching.
Kili huffs and pushes his brother back, then starts eating. By the end of their meal, Fili is almost laying on top of him. All warm and cuddly like he always gets when they're separated for too long. Yet today, Kili doesn't seem able to relax. "Is it the hunting thing that is stressing you out?" Fili asks while his brother slowly combs his hair with his hands. Of course he noticed, he always does! Kili sighs as an answer. "We'll go together, tomorrow." Fili smiles, looking up at his baby brother. "Do you want a massage? You look all stiff".
Kili all but frowns, a bit taken aback by his brother's proposition. They're extremely close, sure, but a massage? Not very in Fili's fashion if you ask him. His confusion must've been clear on his face because his brother raises to a sitting position, throwing the blanket aside and cracking his knuckles. "Okay this might seem weird to you but I did learn a few things back in the Iron Hills". "Massages, are you serious?" Kili barks a laugh. "Is that what you learn as a crown prince on a diplomatic mission?".
Fili holds up his hands in front of him in a pacifying motion "Wait wait, it's not the only thing I did, but I did learn some pretty cool stuff. People there are very fancy about a lot of weird customs" With who? When? How? those are the questions that are burning Kili's tongue, but as close as he is with his brother, he doesn't feel at liberty to ask. "Mmh I guess it couldn't hurt..." Kili is still frowning when his brother jumps to his feet and goes to his bathroom, telling him something about how he saw some oils that would do the trick earlier, and how good Kili will feel after.
When Fili comes back, a small vial of beard oil in his hand, his brother is already laying down on his day bed, his night shirt thrown carelessly on the ground on a cushion that fell during their meal. Fili wastes no time and straddles Kili's thighs, unplugging the vial and pouring a bit of oil on his hands, warming it up. Kili huffs under the weight of his brother on him, even for them the position feels weird, he looks up over his shoulder to see what his brother is doing only for Fili to push him down by the shoulders, his warm hands already starting to work the knots on Kili's back. "Don't mind me, just relax."
Kili does just as he's told, resting his head back in his arms and letting his brother work his magic. There's none of the delicateness one would expect of a massage, Fili's hands are rough and his technique is not that good, but Kili finds himself soothed by the motions the more he focuses on them. He hears Fili's jewelry clinking softly, the sound of their clothes lightly brushing together and the huffs his brother sometimes makes. The massage rocks Kili into a near sleeping state, now he feels Fili's hands on the middle of his back, pressing on his ribs and lower back, then his hands slide back on his shoulders. Kili feels his brother shift on him slightly, the oil is getting warm from all the friction of Fili's hands. He massages the back of his neck and kneads his shoulders, then gives longs strokes over Kili's sides and ribs and lower to his waist and hips. Then back up and down again.
But focusing on all of this touching does not serve Kili well, he squirms a bit under Fili, his breeches just a tad uncomfortable. "Shush!" Fili chastises him with a laugh, pressing harder on his little brother's shoulder muscles and pushing him down. With his voice so close to him, the pressing of his hands and Fili's weight on him, this is not helping Kili's situation. He feels trapped but in the best way. Everything around him is warm and soft and the presence of Fili is so very reassuring… But if his brother sees his hard on when the massage ends, when Kili stands up to wash off the oil, he will never let him live it down!
Kili shifts a bit, burying his head in his arms again, digging into the soft pillows with his face to try to muffle the embarrassment already ringing in his ears. Why does it have to react right now! Normal bodily functions and all that, but still! There is nothing calling for it right now. Fili has started to go from the top of his brother's shoulders to the bottom of his back in long, strong strokes. Up and down, up and down, he goes a few times until Kili notices. Fili (surely inadvertently, Kili is sure of it!) is rubbing his hips against him. A few more strokes and Kili is sure of it, he can feel it, Fili's hard length pressing against his ass.
In an instant Kili has made up his mind, he has to move or things will get very weird pretty fast. He starts to straighten up, "Uh I don't feel so good Fi, let me take a little break?" but he's pushed back down by Fili, both hands on his back, pinning him to the mattress. "Stay here for a bit okay?" Kili hears him closer than he was before, Fili's body draped over his back. The blond is holding him with one arm around his torso and one hand resting on his hip. Kili's body, relaxed by the massage, feels boneless in Fili's arms, and he finds himself pressing against his brother. He hears Fili taking a sharp breath, grinding slowly. All the Gods be damned, his mind telling him to stop be damned. Kili clutches at the sheets under him, his own grinding becoming more obvious as he feels Fili's clothed erection pressing on his ass.
Kili's body feels like it's going to explode, he feels his own hands undoing the front lace of his breaches before his mind can even catch up on what's happening. Fili's hand finds his length a few seconds later, jerking him in rhythm with his own grinding. Slowly their moans fill the room, they're breathing the same air, staying close together. Fili's blond hair is falling around Kili's face as his brother buries his face in his neck, moaning and pressing kisses where he rests. Kili wouldn't have even dared to dream of feeling Fili's hands on him, but his whole body is flushed with it and he needs more. With one swift move, Kili finds himself on top of his older brother. Out of breath, they both stare at each other, Kili's hard dick out while he's straddling Fili's hips where Fili's clothed hard-on left a wet stain on his linen pants. They search each other's faces for something, a wish to stop, a wish to keep going. And after a few beats looking at each other, they lunge into a kiss like Kili has never known before, like he never knew he needed. It's all tongue and teeth and gasps. Bent down on Fili, still straddling his hips, Kili presses down with his ass onto Fili's dick, grinding on it and getting a few gasped moans from the blond's throat. His brother's hands are all over him, his tongue on his neck, his breath so close to his skin and his moans are filling Kili's brain. The brunette ravishes Fili with the exact same energy. For a few minutes they kiss, exploring each other and touching every part of the other's body.
As Kili urges him to take his shirt off, Fili throws his brother back down on the mattress, undoing Kili's pants all the way and discarding them, he trails down his torso with kisses. His blond hairs are so soft against his hand, and Kili can't help but trailing his hands down against Fili's chest hair. This is everything he didn't know he missed. Fili takes his time circling Kili's nipples with his tongue, squeezing his chest with his other hand and letting his teeth nip at the hardened bud just enough to get a small gasp from Kili. Never in his life he could've predicted or even dared to want the view currently in front of him. Fili, the crown prince of Erebor, his lifeline, his blood, his own brother, currently peppering his chest and belly with kisses and now giving open mouth kisses to his pubic hair and the base of his dick. After a last heated look at his lover, Fili hooks one of Kili's leg over his shoulder, pressing on the other thigh to open up his legs.
He starts with licks and kisses. Then wrapping the one hand that is not holding Kili's thigh open around the base of the brunette's dick. Fili takes the tip in his mouth and, for this moment until when his cock hits the back of his brother's throat, Kili thinks he sees the light. He's tugging at Fili's hair, moaning and gasping as his warm mouth surrounds him. It goes until Fili has to hold down his hips to restrain him from forcibly fucking into his throat, which turns Kili on more than he could've ever imagined.
He doesn't even hear the noise of the oil vial opening or feel Fili putting some on his fingers. But he feels as his brother slightly pushes against his entrance, big questioning eyes now on him, as his cock is released from Fili's mouth for an instant.
"Please. Yes" is the first real words that come out of Kili's mouth except for all of the moans and gasps since this all started. He tried to not appear too desperate but given how dark and lustful Fili's eyes have turned, he did not succeed.
Next thing he knows, Fili's mouth is back on him and a finger slides in. Kili can't help the gasp that escape him, this is the first time he's been receiving with a male dwarf and this doesn't escape his brother's ever watchful eyes. After the burn fades a second is added, Fili massaging him deep and slow, then a third. Prepping Kili for some longs minutes, Fili's mouth has turned back to some licks and teasing and Kili feels like he's going to explode. His dick is leaking, red and angry and his brother is diligently licking all the pre come he can get his mouth on.
Kili's body feels so warm and his head feels like filled with cotton. He can hear his voice, hoarse from the moaning as he begs his brother for more. Only a little push and Fili is off of him, carefully taking his fingers out. And in an instant Kili is on his knees, shamelessly bent over, and if it was any other time he would be dying with embarrassment but all he wants right now he can and will get. A look over his shoulder gets him a glimpse of Fili looking at him with a lust he never ever seen on his brother's face. Suddenly Fili's tongue presses into his hole until Kili feels his entrance open up around him. He gasps at the feeling of the wet, slick muscle licking deeper in. The shape of it, dragging against his walls. His thighs shake, and he tries to move but is held in place by Fili holding his hips still and licking deeper into him. This can't be happening right now! Oh the groans that come from Fili tell him all he needs to know about how much the other enjoys it. He tries to not clench, and to not grind against the face eating him out, but he can't help himself. Fili answers with a chuckle. The vibrations of it has the heat pooling in his lower stomach. Kili's cock is hard, non-stop leaking on the furs of the day bed. When Fili hears the moans and when the bucking reach an all-time high, he stops, takes Kili's cock in hand and squeezes at the base of it.
"Not yet" he says in Kili's ear, blanketing him with his body and lining himself up. Slowly plunging into his brother's body, Fili is holding him by the waist and pressing the other hand on his stomach. The stretch makes Kili hiss but he focuses on the kisses Fili gives to his neck and his face, whispering to him when to stop to let him adjust and when to keep going. The oiled-up cock sits so deep once Fili has bottomed out, the burn fading as he starts to move after leaving some time for Kili to adjust.
Kili grabs a pillow to burry his face into, holding it in his arms and drowning his moans in the soft fabric. If he were to be without it, his voice would have been loud enough to wake up the birds sleeping at the very top of the Lonely Mountain, he's sure of it. Somehow Kili still can't believe this is happening. The wet noises of their bodies and of their skin slapping against each other is obscene and Fili's dick feels so good, leaking into him and slowly filling his belly up. He squeezes a little at the idea of being filled up by his brother, making Fili moan and speed up his pace at bit, changing position to grab both sides of Kili's hips, driving himself harder into him.
The sounds that come from his Fili's mouth are a mix of groans, moans and Kili's name. He's fucking him deep and slow, sometimes thrusting a little harder than he probably intended, shuddering, trying to keep control and stop himself from coming right then and there. Kili feels so full, grabbing and pulling at Fili's hair when he's a little too close, his brother squeezing his dick while whispering "Not yet, not yet" in his ear.
Both of them are not more than an incoherent mess after a few minutes, Kili starts to push back his hips, matching Fili's thrusts, pushing his brother to go deeper and faster with each pass. Moaning and calling each other's names, Kili comes to his release with a cry, feeling his brother inching impossibly deep inside his belly. He lets himself be used until Fili comes and fills him up, a warm wave of pleasure coursing in his veins thanks to the desperate gasps of his brother and the feeling of the copious amounts of cum Fili gives him.
Fili's softening cock slips out of him as he lays down with a grunt on the furs of the daybed besides Kili. Basking in his afterglow, Fili feels the weight of his brother slip, then his warm arms coming to encircle his chest, the younger nestling his face in Fili's neck as his turns a bit to the side to take him in his arms as well.
They lay here for some time, so warm in the low lights of the candles, Kili's hair smells so good. Fili guides Kili's head up by sneaking a hand along his jaw and kisses him, sweet and slow.
"I think we need to take another bath, if we let that set our skin will be all dry tomorrow" Fili's voice is rough from the sex. Kili smiles lazily and nuzzles into his chest "Mmh, we certainly can't let that happen, can we?".
