****** Sam's Mouth Is Filth ******
by callmeb
Summary
     John hates his little boy’s mouth, hates it with a passion. He wishes
     he could tape those lips shut, sew them shut, clip his vocal chords
     so the kid can never speak again. Because that kid’s mouth is sin.
     Because every word that comes out of Sam’s mouth is filth. Dirty,
     obscene, filth.
     Warning: Sam is 12
Notes
     Once again, I wrote something new instead of working on longer
     stories that are piling up.
     Dub-con on John's side, not Sam's.
     Callmeb is the author of this story.

John hates his little boy’s mouth, hates it with a passion. He wishes he could
tape those lips shut, sew them shut, clip his vocal chords so the kid can never
speak again. Because that kid’s mouth is sin. Because every word that comes out
of Sam’s mouth is filth. Dirty, obscene, filth.
The things he says, 12 year olds aren’t even supposed to know about. John has
no idea where he learned them from, or when. All he knows is that he can’t be
held accountable for what happens when his sweet little Sammy says the things
he says.
“Daddy, can I touch you? Will you touch me? My cock is hard and I need help,
Daddy. Rub your hand against my cock. Rub your cock against mine. Yours is
leaking, Daddy. Gotta clean it up. With my tongue, not your hand, silly. Put it
in my mouth, I wanna taste your cock; it looks so good. It gets my mouth all
sticky. Mine leaks too, but not as much as yours. I like yours better; can I
make it even bigger? Can mine get bigger, too? Wanna feel good. Make me feel
good, Daddy.”
And John tries to say no, tries to tell his son to stop. John is so appalled
the first time that he can’t even think fast enough to stop the boy from
rubbing off against his hip. And when he tries to pull Sam away, the kid gives
him that face: lips pouting, lower one quivering; cheeks red with
embarrassment; eyebrows high on his forehead; and his eyes – wide open, half
the color pushed away and replaced with black, what color is left is always
changing. And John spends so much time mentally cataloging the different hues
and the way those eyes reflect the light so beautifully that he doesn’t even
know what’s happening until Sam’s got his cock all the way down his tiny
throat.
Sam takes it all, every single inch, like a pro. He pushes his own face down
until his nose is hidden by dark curls, and the kid seems to love that. He rubs
his face in John’s pubic hair, giggles when it tickles his nose, and lets out
happy sighs around the flesh in his mouth as he tries to burrow deeper. Sam
even likes to play with his balls. He slides his fingers around John’s sac and
just twirls the hair there, making the man gasp when those small digits prickle
goose bumps from the most heated part of his body.
And then when Sammy moans, Jesus, its sounds only a child can make. And that
makes it all the worse when John spills pre-come as his little boy, his son,
whines so pathetically around his cock; as a fragile, hairless body rubs
against his leg; as a little, wet cock rubs into the coarse hairs along his
calf. But it makes Sam whimper more, high pitched, cut-off noises that John can
feel vibrate along his skin.
When his boy pulls of his cock and starts climbing up John’s body, he tries to
say no. He wraps his hands around Sam’s thin arms to hold him back, but that
kid is talking again. That mouth is running lewdly, hot breath hitting his face
until Sam can reach up to John’s ear and whisper.
“Daddy, it’s so big, I want to feel more of it. I want to feel it inside me. I
put my fingers inside earlier, Daddy. Thought about your cock while I touched
my insides. I can squeeze my fingers really hard, Daddy. I bet you’d like it. I
already opened myself up so you can slide right in, so your cock will fit
inside me. Stay still, Daddy, and I’ll sit on it. I know it can fit. I’ll make
it fit, Daddy; I need it to fit.”
What’s a man supposed to do when a tight hole is suddenly pressing against the
tip of his cock?
Say no, obviously. But John clearly can’t think straight because those words
are running through his mind. His little boy stretched his own ass open just so
he could sit on John’s cock. That pressure against him is his little boy trying
to fit his fat cock in his small body. The only thing John is capable of doing
is stay still like Sammy asked so that he doesn’t thrust up into his son and
hurt the boy.
His cock never fits at first; Sam just gasps and lets out little cut-off whines
as he pushes down on John’s cock. The wet tip nudges at furled skin, prods at
the opening as Sam moves up and down John’s body repeatedly. He takes a few
centimeters at first, works half the tip in after a few tries, and then the boy
is impatiently pushing harder with every downward stroke of his body until the
head finally pops all the way past the ring of muscle.
John feels his boy put that sinuous mouth against his neck, feels teeth scrape
at his rapid pulse and wet lips entrap a circle of heat. He feels hot air
rushing out of his boy’s nose until the heat brings sweat bubbling out of his
skin. John keeps his entire body stock still, hands still gripped at his boy’s
arms, neither pushing nor pulling. He can’t even form words besides
occasionally breathing out ‘Sammy’ – in halt or pleasure, John is never sure.
Sam’s small body rocks against him; his frame is half the width of John’s, and
the man feels soft nipples against his ribs. He feels little fingertips digging
into one shoulder, another hand flat at the side of his pec. He feels a hard
prick poking just below his navel. With every move, John feels his cock sink
just a little bit deeper, more heat pulling and squeezing along his length with
a whine at his throat to punctuate each inch his boy takes. Until Sammy is
pulling away from him, sitting up straight in John’s lap, and that’s when he
feels the meat of his son’s ass pressed flat against his upper thighs, and
knows his little boy has the entire length of his cock inside him. And he sees
those lips moving again, shining in the darkness of the room. That voice that’s
a few octaves too high makes even the most vulgar things sound just a little
bit sweet.
“I told you it would fit, Daddy. I took it all. It’s so big, though. I don’t
think I stretched myself enough, I’ll put more fingers next time so it won’t
take so long. Wow! I feel it in my tummy. Put your hand here, Daddy; can you
feel your cock inside me when I move? I can. God, I feel like it’s gonna poke
right through me! It feels so good, though; way better than my fingers. My
fingers can’t reach as deep, aren’t as fat as your cock. I’m gonna ride it,
okay, Daddy? Gonna bounce on your cock and it’s gonna feel so good.”
And he does, and it definitely does. Sam’s legs clutch at the outside of his
thighs and his hands splay right across John’s nipples as the boy moves. His
son pushes against him as he lifts his body and lets his ass slam down so hard,
the man is worried that he’ll hurt himself. But his face only shows pleasure,
his cries morph into moans, and he repeats the action without pause.
He does it over and over. San’s thighs shake with the effort to move steady and
rapid. His hands squeeze and release John’s skin without rhythm. His chest
heaves with every suck of breath, shakes with every sudden cry of pleasure. His
little boy works himself up and down John’s cock, forces groans and moans and
spills of pre-come.
He keeps his palm on Sam’s flat belly. Sam was right: John can feel his cock
stuffing his boy full whenever he drops down onto it. And John feels his son’s
skin, both hot and cold at the same time. Sweat prickles out of the boy’s body,
turns cold from the air and makes Sam shiver. His mop of brown hair lifts and
falls against his head with every bounce. Some stays still, messy strands stuck
to his glistening forehead. John’s body turns to fire; his skin burns with the
wrongness of everything, especially when he can’t force himself to close his
eyes, has to watch his little boy bounce on his cock.
And when John watches his boy’s face again, he has to dig fingernails into his
own thigh to stop himself from coming. That filthy mouth is open. Sam’s lips
are dry because the boy is too busy chanting ‘Daddy, Daddy, yes, Daddy, so
good, Daddy’ to have time for licking the plump skin. His cheeks are flushed
red; John almost chokes when he sees a wet drop of pre-come, presumably from
the blow job, sticking a strand of wiry pubic hair to his son’s face – a
reminder that his little boy had his mouth down there; that his tongue probably
tastes like John’s cock. And Sam’s eyes are always open, watching John as he
moves. And once he meets those multicolored orbs, so wide in feign innocence,
John can’t look away.
That’s how his little boys comes. Their eyes lock together and Sam’s body loses
its pace, he starts shaking, and he can only rut down hard in John’s lap. Sam
won’t look away, won’t close his eyes. He just pulls his lips further apart;
open mouthed moans poison the air, and his hole starts convulsing. His body
grips John’s cock harder than the man’s ever felt anywhere else, and Sammy
cries out ‘Daddy’ as he takes John greedily and he comes on the man’s stomach.
And his little body hasn’t made seed yet, so when his son orgasms, when that
young cock spurts a small pool of hot juice out the tip and onto John’s body,
it’s clear fluid, thinner than what his own load will be.
And knowing his little boy is coming because John’s cock is inside him, fucking
his tight asshole, brings him right to the edge. And his little boy’s ass still
moving up and down, clutching and tugging, pushes him right off the edge and
into the deep end of pleasure. He explodes inside Sam, loud and gut-wrenching
and hard. And the kid doesn’t stop moving until John is whimpering with
overstimulation.
He pulls off John’s cock with a wet pop, and sits right back down on top of the
heated flesh. The tip of John’s cock pushes past his boy’s ball sac, still
leaking white seed, some of it mixing with his son’s clear come. And of course,
the kid speaks again, more corrupt words that John knows he will never be able
to erase from his mind.
“I made a mess, Daddy, but I’ll clean it up. I’ll lick it all up and swallow it
so you don’t stay sticky. It tastes funny, doesn’t taste the same as your cock.
Daddy, how come yours is a different color? How come yours feels thicker on my
tongue? Where is the rest of yours, Daddy? Is it inside me? Yeah, it is, isn’t
it? I can feel it, makes me feel so full. But I want it in my mouth, Daddy.
Pull it out of me with your fingers so I can eat it. Please, Daddy? I like the
way it tastes.”
John really doesn’t have a choice when Sam takes his hand and shoves two
fingers inside him, makes John pull out as much seed as he can. It’s not his
fault that Sam brings those wet fingers up to his mouth and makes John feed him
come. He can’t help it if his cock twitches enough for the boy to insist taking
it back in his mouth – to clean it, Sam claims.
And if letting his 12 year old son suck and ride his cock isn’t enough to
guarantee John a spot chained to the Devil’s bed for all eternity, then he’s
sure letting his 16 year old son watch every single moment while he jerks off
is the cherry on top.
But really, it’s all Sam’s fault, with that mouth. That mouth that should not
be allowed to exist.
