Kili pulled Fili into the seclusion of the bathroom. He quietly slid the lock as to not disturb the people sleeping in the house. Nori and Bofur were asleep on the sofa, piled ontop of eachother like exhausted puppies. Oin was fast asleep, his snoring could be still heard even through the closed door. Only a few minutes ago Thorin and Bilbo settled for the night leaving Fili and Kili with some free time with little personal space.

"You sure?" Fili asked. "You're leg and the place."

"I almost died a couple of times," Kili put down the lid of the toilet and put a bottle of oil on it. "I'm not chancing another slow dance with death without…" He frowned trying to figure out the right words. "'being fucked', is not what I want to say but 'making love' isn't right either."

"Charming way of putting it, but I get it."

Fili turned on the shower as well as the sink, creating as much noise as possible in hopes to mask what they'll be doing. He shucked off his shirt, quickly removing his trousers and pants as well. The naked skin of Kili pressed up against his back, hands snaking around his chest and abs. One hand went up, covering his mouth as the other went down, passing over his cock to cradle his balls. Kili's mouth clamped over Fili's neck, giving a lovely suck making him moan. His tongue flicked out between the brunette's fingers pleased when Kili let him suck a few fingers into his mouth.

He turned around fingers dropping from his mouth. He took hold of Kili hips, rutting up against his boyfriend. Kili started to moan, Fili quickly claimed his mouth muffling the sound with lips and tongue. He moved back, sitting on the edge of the bathtub, he turned Kili around pulling him down onto his lap, careful of Kili's injured leg.

"Wish we were doing this on a bed." Fili murmured against Kili's back. His hands roaming over every space of skin he could touch. The little shivers that Kili gave lit his body on fire. He could imagine the way Kili bit his lips in desperation to not make loud sounds.

He kissed and licked up Kili's back, stopping to give sucks and bites. He smirked as Kili began to quiver, he wanted nothing but to tease more but in a house full of people their time was limited. He reached forward, bending his lover forward as he grabbed the oil. He murmured a "thank you" against skin as Kili unscrewed the top of the oil and poured some onto Fili's hand. To spread the oil over his fingers, as one arm was firmly wrapped around Kili's waist, he took hold of Kili's growing erection. He slid his hand up in a long pull, squeezing a little encouraging the oil to spill over his fingers. Kili put a hand over his mouth as a whimper escaped him. The tiny tremors of pleasure seemed to bite at his skin, rippling with such a wonderful infection that heated his body. His head fell back onto Fili's broad shoulder as his balls were cupped, a finger slipping across the sensitive span of skin just behind his sack. The feeling of tongue and teeth, the prickle of whiskers and the brush of Fili's soft, fluffy, hair only added to the elixir of decadence that he willingly drank.

"Pour oil on your cock." Fili whispered into Kili's ear, his voice heavy with lust. The way Kili shivered in his lap, the sounds he made as he tried so hard to be quiet. His smell, his taste, it all fuelled his desires, making his cock rock hard.

The oil was cold, quickly heating up with the fast pumps he gave. Kili's free hand gripped the side of the tub, his hips bucking into Fili's hand causing Fili's cock to rub against his entrance. Fili bit Kili's shoulder panting around his mouthful, drool slipping down making Kili's tingle even more. Then he was being moved up, fingers at his entrance, one pushed in, probing with no troubles, the second stinging slightly soon after. He took a few deep breaths forcing himself to relax as Fili scissored his fingers for a good while before risking a third.

Kili made a sound of distress that caused Fili to pause, letting him have time to adjust as he kissed Kili's back and whispered words of love and encouragement. Before he knew it Kili was thudding down onto him, giving his hips a little, experimental, swirl. Fili's arm around Kili moved up, moving the brunette's hand from his mouth to clamp his own hand over lips. He started to prod, trying to find that spot. The muffled scream and the sudden thud down onto his fingers made him grin.

"Fuck, that was a beautiful sound." Fili groaned, his cock twitched with need. Never before had he wanted to get inside of someone so badly before in his life and by god he wasn't going to lose control. Though, when one of Kili's hands gripped his wrist and he made a pleading sound he really, really wanted to just plunge right in and fuck his boyfriend until he couldn't walk.

He barely had enough mind to pull out his fingers and hold out his hand. "More oil."

Kili's hands shook as he poured a messy amount of oil onto Fili's palm. Fili quickly coated himself, the rest he smoothed over Kili's butt cheeks as well as around his lovely stretched pucker.

Slowly, carefully, he pushed the blunt head of his cock into Kili, hissing as he took great care to move as slowly as he could before his boyfriend was settled on his lap. Now Kili was fully shivering. Fili moved as best as he could, hooking Kili's legs around his own as he spread them apart, a small mirror across the bathroom caught his eye. Kili's eyes were closed, holding on Fili's wrist and arm for support as he was kept quiet with a hand. His legs were spread beautifully wide, his cock standing with leaking pride. It was breath taking and it only made him buck up at a time he felt was too soon. Yet the sound from Kili only encouraged him to move again, picking up a rhythm akin to the bobbing he remembered having to do in horseback riding.

It felt so good and seeing Kili's expressions in the mirror was so enticing. He kept one hand over Kili's mouth as the other started to pump Kili's cock. Oh, god, those sounds. High and wanting. Kili clawing at his arms, tears of pleasure spilling down his cheeks.

They both came too soon, but it did not make it any less of a wonderful thing. When Fili pulled out he slid back with a hard thump into the show, the water cold.

He had to take a moment, holding Kili close, placing kisses on his head before he could move properly. Kili was quicker to recover, getting a sponge and soap. He carefully cleaned Fili and himself, his body still shaking, now though, mostly from the cold water than the aftermath of their sexual encounter.

"Next time, we're definitely doing that in a bed." Kili smiled, then he bit his lower lip, still smiling that devilish smile. "Soon."
