Summary
     It starts in the middle of the night when Dipper finds a X Rated
     video on TV, and Stan catches him watching him. Like any good
     parental figure, Stan punishes him for watching things he shouldn't
     be watching, right?
     Yeah, things don't go so clean cut as that.

It started on a night when Dipper was bored.

Mabel was over at one of her friend’s house, Wendy and Soos had gone home for
the night and Dipper was left to his own devices while Stan was off doing who
knows what.  He was spread out on the carpet, lying on his stomach with his
legs in the air and his chin in his palm, watching television.  It was nothing
very entertaining, but it was better than nothing.  There was probably an hour
into what was becoming a process of completely numbing his brain when Grunkle
Stan shuffled into the room.

“Sheesh kid, you look dead.”
 
Dipper didn’t even look away from the screen but simply moved his legs closer
to the middle of his back so they would be out of the older man’s way as he
walked to his chair.  There was the sound of the seat sagging and Stan letting
out a sigh of contentment from behind Dipper but he still never took his eyes
off the TV.

“Bored.”  Was all Dipper said in response to Stan.  The man grunted in return
and the two watched the TV mindlessly for a while as Dipper’s head slowly
slipped from his hand to resting on top of his arms.

Dipper must have fallen asleep because the next thing he knew, the show he was
watching was long over and he could hear Stan softly snoring behind him. 
Shifting onto his side and turning his head, Dipper was able to confirm that
Stan was indeed asleep in his chair.  The old man’s was resting on his shoulder
in a way that Dipper was sure that he was going to have a crick in it the next
day.

Sighing to himself, Dipper reached for the remote which was lying on top of
where he had thrown his vest and hat earlier and fumbles a bit with just barely
touching it before he finally just moves a bit and actually grabs it.  As he’s
settling back into his position, Dipper’s fingers slip and hit some random
numbers.  The TV screen turned to fuzzy static for a moment like old TVs do
before settling onto a new channel.

Smooth jazz filtered out of the speakers, making the preteen quickly smash the
lower button on the remote before quickly looking to see if it had woken the
older man.  Stan grumbled a bit but went right back to snoring, making Dipper
sigh with relief and turning back to the TV to see what was on.

What was on the TV was definitely not something he should be watching, was what
Dipper quickly realized as he saw a woman pull off her shirt and expertly
unclasp her bra.  Her large breast sprung free and a man who was waiting
immediately started forward and took one nipple into his mouth and cupped the
other breast with his hand and squeezed.

Dipper felt his whole body stiffen with the realization that this was
considered wrong for him to watch.  But, he didn’t dare change the channel and
instead watched with wide eyed fascination along with other feelings he didn’t
know.  Watching as the man on the TV took his dick out of his pants and began
rubbing it, Dipper’s own hand followed by example and slowly slid under himself
and against the carpet until he was rubbing himself through his pants
experimentally.  A shutter of pleasure shot through Dipper, making his head
spin briefly.
Licking his suddenly very dry lips, Dipper is mesmerized as the topless woman
makes a show of running her hands up and down the man’s length, before settling
down on her knees and moving her head closer.  She gives him a rather coy grin
before taking slow, deliberate licks on the head and then actually taking his
dick into her mouth.  The woman starts only with the tip, but slowly starts
bringing more into her mouth until it seems she has it all in and the young boy
can only gape with wonder and press harder against his pants. 

A warm jolting feeling is coming alive inside him that he’s never felt and it
almost feels like butterflies and lighting striking at once below his stomach
and it’s making his head rush even more.  Pawing at his pants and becoming so
focused on watching the television and his new found pleasure, Dipper didn’t
realize that he didn’t hear Stan’s snoring anymore.  His eyes are starting to
flutter shut from his touching and a small moan slipped out, surprising
himself.  Starting to gnaw on his lip, Dipper is thinking that actually
touching himself, not just rubbing himself through his shorts when there is a
noise from behind him.

“Dipper, what the hell are you watching?”

The young boy lets out a shriek and immediately pulls his hands away from
himself and attempted to change the channel.  But, in his hurry to pull his
hands away from himself, Dipper had accidently flung the remote half way across
the room.  He knows there is no way he can just turn off the TV now.  Lowering
his face until he is just face first in the carpet, Dipper wants to throw
himself into the bottomless pit.

“Dipper, look at me.”

Slowly, the brown haired boy rose onto his knees and turned to face Stan with
cheeks blazing and can barely meet his eyes.  Stan is staring at him with a
stern and angry look and Dipper bites his lip.  The old man doesn’t say
anything though when Dipper expects him to, so he chances a look up.
Stan was looking between the television screen to looking at Dipper…well, it
didn’t seem like he was looking at him directly.  In fact, it looked like Stan
was looking lower.  Dipper looked down and flushed even hotter.  His pants were
tented and it was incredibly obvious about why.  Shoving his shirt down over
his pants as much as possible, Dipper had to bite back a moan.  Just the simple
movement of shifting his shirt over himself was sending his already sensitive
body into an electrical frenzy of newfound pleasure.

The old man was staring at him intently now and for a second as Dipper is
trying to keep his breathing steady, he thinks he sees Stan take a deep gulp.

“Come here.”  When Stan speaks, his voice seems gruffer than usual, like there
is something stuck in his throat.  The man points to the floor in front of him
and not wanting to get into anymore trouble then he is probably in, Dipper
awkwardly shuffles across the floor on his knees to where Stan wanted him. 
Dipper stares at Stan timidly, unsure what Stan is going to say.

“You know you shouldn’t have been watching that.”

Dipper can only nod; speaking is too much at the moment.

“You knew and you still watched anyway.” 

The kid looked down at the ground shamed faced, embarrassment and the still
lustful feelings making his head swim and his eyes water.

“I’m gonna have to punish you kid; I’m going to have to teach you why you
shouldn’t watch things like that.  Sit up straight and look at me.”  Stan’s
voice was commanding and Dipper immediately sat up and he looked at his Grunkle
with dread.

Stan was still staring at him with that intense look that Dipper had no chance
of deciphering.  The man reached out and Dipper could barely hold back a flinch
as he was sure he was going to be hit him or something, but instead, he put a
hand on Dipper’s shoulder and pulled him forward and making Dipper shuffle up
further so he was directly in between Stan’s spread open legs.  Stan’s much
larger hand rested on Dipper’s shoulder, rubbing it in a much gentler fashion
then Dipper thought his Grunkle would at a time like this.

He wondered what Stan was going to do, how he was going to punish him.  When he
stared at Stan, the man seemed to be locked in a mental debate with himself. 
Sighing and closing his eyes for a brief moment, when Stan opened them again
his gaze seemed even intense than before.  His other hand that wasn’t currently
rubbing his shoulder lowered from the arm chair and onto his leg.  That hand
made its way to the top of his boxers and Stan dipped his thumb inside and
quickly pulled it down and maneuvered around his half hard penis so that it was
out in the open.

Dipper just stared in shock and confusion, and to add even more confusion to
that, his hormones sent a jolt of arousal to his crotch again.

“I-I don’t understand…” Dipper looked away from his Grunkle’s exposed penis and
looked at the man’s face in shyness instead.

“Well, you watched the TV didn’t you?” Stan gestured towards the screen which
was still showing the porno.  “If you watch shit like that, you’ve got to
commit to it.  So, get to it.”

Swallowing a bit, Dipper looked away from Stan’s eyes and slowly turned his
eyes on the dick in front of him and just took it in.  It was much bigger than
his and Dipper wondered if his would get to be this size.  Hesitant to touch,
Dipper first touched Stan with only the bare tips of his fingers; just gently
touching running them up and down the length.  Stan gave a small shiver, but
never said anything so Dipper took that as an okay to keep going.

He put his hands around Stan’s dick and began to move up and down like he had
seen on the TV.  Dipper watched wide eyed as it seemed to grow even larger the
longer he did it.  He continued the jerking motion for a bit, honestly just
taking in the curious sensations and learning new things because of it.  Stan
let out a deep sigh and leaned back into his chair, pushing his waist forward
and making Dipper fumble as Stan’s dick got closer to his face.

Dipper knew very well that what was going on was considered very wrong.  He had
sat through all the elementary school plays and live enactments about what to
do if someone touches you or forces you to do something you don’t want to.  He
had learned about good and bad touches and he was about ninety nine point nine
percent sure that this was most likely the kind of bad situations that grownups
had warned him about.  Along with the fact that this was his Grunkle Stan, this
entire situation really did scare him.

But…

But at the same time, while he was scared, his blood was pumping furiously into
his groin like it had never done before.  His head just continued to be a fog
of newly experienced lust and all the excitement and thrill from watching that
video earlier was still inside him, begging for an outlet.  So Dipper moved his
head forward.

Hesitantly, he followed what he had seen on the TV as a guide and stuck his
tongue out and licked the tip a little, just to try it.  Dipper scrunched his
nose up a little bit at the strange taste.  It wasn’t horrible, per say, but it
was different.  With his hands still around Stan’s dick and giving half pumps,
Dipper began to lick slow swipes against the skin on the sides and under.  It
was interesting to him the different reactions he heard from Stan with the
different areas he tried along with the different pressure he used with his
tongue.  Taking a chance as he licked across the tip again, Dipper looked up at
Stan.  To his surprise and the flaming of his cheeks, he found that Stan was
staring right at him.  Embarrassed, Dipper turned his eyes downward and focused
on the task at hand.
Having enough of just trying to lick, Dipper took a deep breath before wrapping
his lips around the length and attempting to take in as much as possible.  Even
before he was halfway down, the tip was hitting the back of Dipper’s throat and
making him gag and his teeth press against Stan’s dick.  Stan hissed and pushed
Dipper’s head back by his forehead, his palm resting on his birthmark.

“Be careful,” The old man gasped.  “Don’t try to shove it all in at once, go
slow if you have to. And watch your teeth.”

Dipper nods just as he would if he was in school and this was a teacher telling
him something.  In a way, this was a learning experience.  He starts to bring
Stan’s dick back into his mouth again, this time, much slower.  As Dipper takes
at least half in again, he can easily tell when he can’t take anymore, so he
focuses on what he has.
He tries to do everything he saw from the TV and while he’s never done anything
of the like before, but Dipper has always been a quick learner and eager.  He
puts both of those things into use as he tries different lengths and pressures
of strokes and licks and sucks in different ways. 
Dipper figures he’s doing a good enough job, even though Stan isn’t making
noises like the guy on the TV was, when Stan’s hand goes to the back of his
head and grips him and pushes himself further into Dipper’s mouth.  The boy
nearly chokes again, but by the chance of taking a deep breath, he manages to
take it before Stan starts to pull back, before pushing back in.
With one hand on the back of Dipper’s head, holding him still, and the other
now hold Dipper’s upper left arm.  Dipper stayed still as possible, breathing
when possible and eyes tearing up when not.  Finally, before Dipper even knew
it, something hot and thick was going down his throat, making him choke and
pull away from Stan and cough loudly.  After a little bit of coughing, Dipper
blinked back the tears that had begun to well up in eyes and looked up at Stan.

Stan was leaning back in his chair, breathing heavily with his eyes closed. 
Dipper watched as he breathed before a sound behind him caught his attention. 
Sitting on his legs, the boy turned his attention back to the TV and blinked
with surprise as the man and woman were still going at it.  Dipper wondered
briefly if the fact they were still going at it was considered normal and if
that meant that Stan finishing so much earlier compared to them was bad or
maybe the video was exaggerated.  Honestly, Dipper didn’t think too hard on it
as the pressure in his pants was still very much present and needing more
attention than that.

“Dipper.”

Turning again to his Grunkle Stan, the old man looked tired but motioned Dipper
to stand up and come closer.  Standing in front of him, Dipper was unsure what
Stan wanted and just stood there.  He felt so shy during this entire process,
so out of character for himself but he just couldn’t help himself.  This
situation was just so new to him.  Dipper was finally going to say something
when Stan leaned forward and wrapped his arm around the kid’s waist and pulled
him onto his lap.  Unsure of what Stan was doing, but opting to trust him,
Dipper relaxed and leaned against his Grunkle.

Stan’s hand rested on his hip, pushing up his shirt just a bit and rubbing his
skin with a tender touch and making a shiver rip through Dipper.  The two of
them just sat there for a bit like that; Dipper leaning against Stan and Stan
just holding him with a single arm.  It was hard to get comfortable for Dipper
though, with the pressure in his pants and Stan seemed to realize that as
quickly as the kid.

“Need some help?” Stan’s question sent even more shivers through Dipper and
without a word, he put his face in the nape of Stan’s neck and nodded, his face
burning.  He could feel Stan chuckle a bit before the shocking sensations of
Stan pulling his pants down and touching him made Dipper shake.

Pulling away from Stan, Dipper turned to watch and gasp as his Grunkle jerked
him off with his left hand.  Clutching his Grunkle’s wife beater, Dipper moaned
and twisted with pleasure.  This felt so much better then when he was rubbing
himself through his pants and he wanted more.  He jerked his hips forwards and
would have continued to do so if Stan’s right hand on his hip hadn’t held him
firmly in place.

“Patience kid; you’re not gonna last long anyway.”  Stan spoke softly.

Stan was right, he didn’t.  Dipper let out a long gibbering nonsense as his
guts seemed to light themselves on fire from the pleasure of his first orgasm
that left him momentarily brain dead.  When he came too, he was still against
Stan’s chest, clutching at him.  Stan must have tucked both himself and Dipper
back into their pants for them, and Dipper appreciate that.  He barely felt
like he had any energy to move, much less try to put his dick back into his
pants.

Dipper was sure he could just fall asleep there in Stan’s lap when said man
suddenly nudged him.  Groaning, Dipper tried to find a place to rest against
Stan but the man only nudged him more incessantly.

“Come on Dipper, you can’t sleep here.  Go upstairs to your bed.”

Weakly opening his eyes, Dipper groaned.

“Oh, but Stan-”

“No buts!” Stan barked out, taking Dipper by surprise by how harsh he suddenly
was and making him jump up and out of Stan’s lap.  “No buts except yours going
upstairs and straight to bed.  Now go!”

Gulping down the hurt he felt, Dipper slowly made his way out of the room.  He
only stopped to pick up his hat and vest which had been left on the ground much
earlier in the evening.  Before he completely left the room, he took one last
look at his Grunkle Stan. 

Stan wasn’t looking at him but instead held his glasses in one hand and held
his other over his face as if he was in pain.  Dipper didn’t stop to think what
this meant, he ran up stairs and into the attic where he slammed the door and
jumped into bed.  Bringing the covers up and around himself, Dipper tried to
push the entire evening out of his mind, along with the hurt he felt for being
yelled at after all that. 

He had no way of knowing that downstairs that Stan was feeling much the same
way.

     I am absolute trash and this entire account is going to be nothing
     but smut and trash and I am so sorry (yet at the same time I'm not).
     But yeah, this is the start of this trash heap. It's only gonna get
     worse from here on out. I think most of these chapters are gonna be
     connected, but in some cases there will be what-ifs or w/e but I'll
     make a note on the chapter titles or beginning notes or whatever.
     Dunno when I'll update but probably not anytime soon. I have other
     stuff to work on and I SHOULD have been working on that but this took
     over my life.
     Well, goodbye until then!
