     Christmas and gets one step closer to the hot dickings he so craves.
Notes
     This was written for catlock-catwings over on tumblr for the Hobbit
     Holiday Gift Exchange! Hope it was appreciated :D
                “Can’t imagine ma meant for this to happen when she paid for me
to visit you,” Kili laughed as he tumbled back onto Fili’s tiny little dorm
room bed. The blonde unzipped his sweater and shrugged it off, then crawled
onto the bed to sit astride Kili’s hips.
 
                “Shut up. I already feel guilty for this, whelp,” Fili stooped
down and kissed Kili before he could keep babbling and tugged up his hoodie. He
bypassed the t-shirt to slide his fingers up, pleased at the warmth of his
skin.
 
                “I’m just sayin’, she paid for me to visit my big brother for
Christmas, not for him to corrupt her little boy,” Kili said once his mouth was
free. He sat up and allowed Fili to pull his sweater off over his head. Fili
pushed his mussed up hair back out of his eyes and found the teen grinning at
him.
 
                Fili pinched his cheek. “Brat.” He pushed Kili down again and
kept up his pinching and poking. “Aw, what a good boy wittle baby Kee is.
Always so worried about what mama thinks. What if she caught you like this,
baby? What then?”
 
                Kili whimpered and batted at Fili’s hands, before he gripped at
Fili’s shoulders and ground up against him as best he could. “Fee-“
 
                “Oh, right. Nearly forgot how much it turns you on when I talk
about it. Sweet underage Kili begging for his trusted big brother to touch him
in his no-no zones and make him come,” Fili smirked, watching Kili bite his lip
and squirm underneath him.
 
                “Please, Fee,” he whined, fingers twisted in the front of
Fili’s t-shirt. “Please fuck me brother.”
 
                “Promise not to bring up ma again this whole visit and I will
fuck you into the mattress,” Fili replied. “Since there’s nearly nothing less
sexy than talking about ma when I’m thinking about how you arch your back and
cry my name when you come.”
 
                “Yes yes yes, I promise, Fee, please,” Kili’s fingers found
their way into Fili’s hair now and tugged. “Please please please please
please.”
 
                “Yes, alright, stop your nagging,” he sat back, settling onto
his perch over Kili’s groin. He leaned back and tugged his shirt off over his
head. Kili watched him and stroked a hand over his furry stomach, appreciative.
His hands settled on Fili’s belt and went about unbuckling it. Fili grinned
down at him. “I have a surprise for you.”
 
                “Are you finally going to fuck me proper?” Kili asked, and Fili
rolled his eyes. Their old argument again. Fili vowed not to actually fuck him
with his dick until he turned 18 and not a second earlier. Kili bitched about
it often since he was seventeen and one big ball of sexual frustration, but
Fili was relentless. Kili cornered him and begged to suck his cock the first
few times Fili refused, talking Kili down and stroking him off tenderly
instead.
 
                They’d worked up to sucking each other’s cocks and fingering
one another open – Kili liked to be penetrated a whole hell of a lot more than
Fili did and he often begged for Fili’s cock. Moving to college had been a
godsend for Fili because then he didn’t have to deny that whining and
whimpering and the way Kili begged with his whole body. He just had to listen
to Kili touch himself late at night, quietly so as not to wake ma or uncle,
stuffing his knuckles into his mouth so that he didn’t cry out too loudly as he
came.
 
                “No,” Fili replied. “You know the deal, Kee. Not until you’re
legal. But I’m sort of giving you what you want,” he said, and he smiled when
Kili looked up at him curiously. He climbed off Kili and fell to his knees,
crawling under the bed for a moment before he snagged a shoebox and dragged it
out with him. He dug out lube and tossed it onto the bed, then pulled out the
toy he’d bought from one of the sex shops downtown not a week before Kili’s
visit. It was thinner than Fili’s cock and curved at an odd angle, presumably
to stimulate the prostate, and Kili sat up and took it from Fili, nearly
drooling as he imagined how good it would feel inside him. It wasn’t Fili’s
cock, but it was the next best thing.
 
                “Wow, Fee,” he looked up from the toy with wide brown eyes and
stared at Fili. A smile slowly spread over his face. “You’re... you’re the
best.”
 
                “I’m just really bad at denying you anything,” Fili said,
really genuinely happy that Kili looked so pleased. “If you finger yourself
open for me I’ll fuck you with it. Sound good?”
 
                Kili nodded eagerly and fumbled to open the lube, nearly
dumping it all over himself in his hasty excitement. Fili watched as Kili
pushed a finger into himself and hissed. Before long Kili was up to three
fingers, curling them inside himself and begging Fili to hurry up and fuck him
already.
 
                As bad at denying Kili anything as always, a second later he
was pushing the toy into him and listening to him let out what could only be
described as a quiet howl, muffled by the pillow. Once the toy was properly
inside Kili, Fili paused and ground it experimentally into him. Any
reservations Fili had had about Kili needing a moment to adjust disappeared
when his brother pushed himself into a sitting-up position on the bed and
fucked himself on the toy. He let out positively whorish sounds as he gyrate
his hips and Fili had to clap his hand over Kili’s mouth.
 
                “Fuck, Kee, I’ve got a roommate, you know. I’m gonna have to
gag you if you don’t straighten up,” Fili warned.
 
                Kili gripped him by the wrist and tugged so he’d remove his
hand from where it covered his mouth. Once he was free to speak he panted; “Gag
me with your cock.”
 
                Fili licked his lips and asked. “Kili, are you sure?”
 
                “Please, oh please Fili, please shove your cock down my throat
and choke me on it,” Kili begged and Fili honestly couldn’t get his pants off
fast enough. Kili took up fucking himself with the dildo while Fili flung his
belt across the room, and after a too-loud whine and a death glare from Fili,
he bit at his knuckles to keep quiet.
 
                Soon (but not soon enough for Kili) Fili’s remaining clothes
were in a heap on the floor and he had climbed onto the bed. He swung a leg
over Kili’s body and sat astride his little brother’s chest. He didn’t need to
hold the base of his cock and guide it to Kili’s mouth because he was leaning
up for it and sucking it down as soon as he could reach it.
 
                Fili grit his teeth and hissed when Kili started bobbing his
head and cursed when he stopped. He looked down to see inquisitive brown eyes
gazing up at him and it wasn’t until Kili’s hand came up and brought his own
back to press the toy deeper into him that Fili remembered that he had a job to
do.
 
                He gripped the base of the dildo and ground his hips into
Kili’s mouth sinuously. Kili took up giving Fili probably the best blowjob he’d
ever gotten (and considering how often Kili ‘practiced,’ that was substantial)
while Fili fucked him with the synthetic cock to match the strokes of his hips.
 
Occasionally Kili gagged and coughed but when Fili began stammering apologies
and pulling back Kili gripped him hard by the hips and forced him down his
throat as deep as he could get and Fili was beyond complaining if that’s how he
wanted to do it.
 
Fili came like that, deep down Kili’s throat and this time when Kili choked and
sputtered Fili pulled back and let him breathe; gasping and coughing up come
and spit. Fili stroked his hair and told him he was so proud of him, how he was
such a good little brother, taking care of him like that. Kili whined and
squirmed and Fili absolutely hammered the toy into him.
 
Kili didn’t come until Fili was whispering filthy things in his ear though,
asking what if ma caught them at this, maybe she has already but was too
embarrassed to talk to them about it, what if she picked up the upstairs phone
receiver while they’re talking each other off? Kili whimpered ‘oh Fee, oh fuck
brother-‘ and then came all over himself.
 
When the toy had been tossed to the floor beside the bed and Fili had crawled
off Kili and pulled him in for cuddles, Kili giggled.
 
“Did I come on your ass?”
 
Fili went a little red high on his cheekbones. “Yeah. A little.”
 
“I wanna come all over you,” Kili decided. “Someday I’ll fuck you and I’ll just
cover you in my come. All around your hole and on your chest and stomach and on
your pretty pretty face.”
 
“’m not pretty,” Fili mumbled and Kili laughed.
 
“Sure thing, Goldilocks. You’re manly as fuck.”
 
“Language, young man. D’you want me to tell ma? She’ll wash your filthy mouth
out with soap.”
 
“I think I like your method of mouth-washing better,” Kili said cheekily and
Fili grumbled ‘oh, shut up’ before kissing him quiet.
