Summary
     Arthur tells his best friend dirty stories at night.
Notes
     The incest in this story is a son fantasizing about his father.
Arthur can't remember when it started. Maybe when they were too young to know
that it was wrong, too young to know what they were doing. But now he's old
enough to know better, and he's still here, sleeping over at Merlin's, and
they're jerking eachother off under the covers.
And Merlin's panting softly, making these nasty little sounds that made
Arthur's arse clench as he pumps his dick into Merlin's grasping fingers.
"Tell me," Merlin says, whispering. It's a secret. It always has to be a
secret.
When Merlin squeezes, tugging on Arthur's dick like a demanding little brat,
Arthur gasps and something switches on inside of him and he finds his words.
"I was in the shower," he says. "Last night. Washing."
"Uh huh." Merlin nudges a broken, open kiss against Arthur's cheek. He urges
him like this, punctuating Arthur's thoughts with soft moans of encouragement.
It makes Arthur feel electric, like he's plugging Merlin in too, firing him up
with the silky hot thoughts that make his dick hard when he fucks his hand at
night.
They're both twisting now, writhing and careful to keep it slow, to last as
long as they can, at least until the story ends. "I put the water on massage
and sprayed it on my arse and I washed myself inside. With my fingers. And
he... he came in and opened the shower door."
Ah, uh huh.
"And he asked, 'Are you clean now, son?'"
Merlin whines.
"'Show me how clean you are,' he said. So I... I turned and put my hands on the
tile for his inspection. And cause... cause it was the shower he didn't use his
gloves like usual, he just got the soap and made his fingers slick and put them
in me. First he washed me more and he put them in me deep. Mmm -- Merlin,
fuck."
"Don't stop," Merlin says, teeth scraping at Arthur's face, mouth open and wet
with senseless kisses.
Arthur catches his mouth, steals a sloppy kiss, and goes on. "He asked me if I
let anyone fuck me, and I said, 'No, sir.' And he told me I was a good boy and
had to be good for him, only for him."
"But he fucks you," Merlin interrupts, hips stuttering. He's never been any
good at waiting.
"He finished washing me inside and washed my balls some too and then told me to
turn around. He caught me getting hard from being washed and I told him I was
sorry, and he told me what a little slut I was, getting hard for his daddy."
"Yeah," Merlin says. "Yeah."
"And I got out and he dried me off and asked me how I should be punished for
getting hard." Arthur stills Merlin's hand. He's too close now. All he can do
is rock, lost in it. He knows that once he comes, it'll wash this all away and
he'll just be making up dirty stories. But right now, right now it's so
perfect, it's so hot, and he never wants it to stop.
"Arthur!" Merlin wriggles until Arthur keeps stroking him, tugging on his
skinny long dick under his pyjamas.
"And I said, 'Please, I won't do it again,' but he didn't listen. He said I had
to learn to be better, and he told me to get down on the floor and made me get
myself wet. I got him wet too."
"With your mouth? Did you suck him?"
"I licked him. He won't let me suck him. He let me lick him until he was all
wet and dripping and then he moved behind me and puts his big dick in me."
"Does it hurt?"
"It feels big."
"Arthur -- I wanna--"
"He did it for a long time and came in me and said I had his jizz in me so I
had to wash again and remember to be good this time. I have to be a good boy
and a clean boy."
Merlin's hand reaches over Arthur's hip in a spastic, jerking motion like he
can't help but try to feel, and Arthur's so close, and it feels so good, that
instead of slapping it away Arthur holds his breath and turns over and bites on
his hand to stay quiet when Merlin's hot, sweaty hand shoves into the back of
his pyjamas and his fingers snake between Arthur's cheeks.
"Arthur, lemme, lemme, lemme," Merlin babbles, pushing up against Arthur's
back, his mouth a moist thing on Arthur's shoulder and neck. His fingers pry
and reach and find Arthur's hole and he freezes like that. "Oh God."
"Don't stop," Arthur says, scraping his teeth at his palm while he holds onto
his dick, his thumb pressed against the slit like that'll stop him, like it'll
bottle it all in. He scoots his leg and props his knee up so Merlin can reach
him better, so he can touch him more, there.
When Merlin pulls his hand away, Arthur swallows back a low moan, a chill of
disappointment running through him. But a moment later, he hears a brief,
snuffling, licking sound and then Merlin's hand is back and it isn't just
sweaty now, it's all wet and slippery and when his fingers return he pushes his
fingertip in, just a little, whispering, "You sure? Fuck, yeah? Lemme? Lemme,
Arthur. Lemme feel."
Merlin has long fingers. The press goes on and on and on, burning and stinging,
feeling fucking strange, like a hot little worm crawling into his body. He
doesn't like it, and tries to squirm away, but Merlin follows him, humping and
screwing his finger into Arthur and then --
"Feels good," Arthur says, moving, trying to get his pyjamas off so Merlin can
do it properly. God, he needs, he needs. He needs. It's so much. It makes him
explode. It makes him shake.
"Oh shit," Merlin whispers, as Arthur comes. "Should I stay still? You're...
grabbing me. Oh God."
Arthur turns back over without thinking, and the movement nudges Merlin's
finger out of him with a brief burn and a weird feeling of relief. He's so
dizzy. He just came so hard he can hardly breathe, and Merlin's looking at him
crazily, his eyes wide and dark.
"It's hot," Merlin whispers. "Inside you."
"Did you come?" Arthur asks. His heart pounds. Hard and fast, like someone
banging on a door.
Merlin shakes his head. His eyes go even wider, his lips parting too, when
Arthur slides down the bed and puts his mouth on Merlin's dick over his
pyjamas, smelling and tasting where he's only ever touched.
"Arthur," Merlin says, pushing on the back of Arthur's head with both hands. He
makes a sound like he's in pain and one of his knees juts out and catches
Arthur's side. "Arthur!"
"Shh," Arthur says, pooling spit on his tongue and using it to get the cotton
all wet. It sticks to Merlin's dick. He can feel everything like that.
"Come on, please," Merlin says. It sounds like he's going to cry. "Please.
Please, Arthur."
Arthur takes the band of Merlin's pyjamas and tugs, slipping them down to
Merlin's thighs as Merlin lifts his hips to make it easier. Merlin's dick
springs up and brushes against Arthur's cheek and he grabs it and guides it
into his mouth, feeling his way because he's never done this and it seems scary
now. Except it's Merlin, and Merlin isn't scary.
He doesn't have to do it for long. Merlin jerks and flails and comes as soon as
Arthur starts to figure out how to suck.
It fills his mouth, hot and slippery and tangy. Mystified, Arthur spits it back
out, watching the way his spit is thick and white as it rolls down Merlin's
pink, hard dick and over Arthur's knuckles.
Arthur wipes his hand clean on his thigh and pulls Merlin's pyjamas up. He can
feel Merlin breathing hard and shaking, so he pulls the covers up too, up over
both of them like a tent that's hot and smells weird inside, but it makes them
alone and warm and it's always made Merlin sleepy.
It works. Merlin wraps his arms around Arthur's neck and moves until he's using
Arthur like a giant body pillow. He falls asleep still trembling.
Everything starts to go far away as Arthur gets sleepy. The dirty stories fade,
but the heat at his backside remains, the warm sting where his body remembers
that Merlin touched inside of him.
