****** Dirty Shorts and a Guitar ******
by quagsirechannel
Summary
     A collection of NSFW requests I've done for Robbie/Dipper. It's
     called Dirty Shorts because Dipper doesn't bathe and wears shorts and
     these are all short porn stories, get it?
***** Lonely Nights *****
Chapter Notes
     In Chapter One we have Dipper jacking off to the thought of Robbie
     while his poor sister sleeps next to him. Also he's like 12. Because
     I'm classy.
     Request was from ladlekind@tumblr.
     "REQUESTS U SAY„,dipper bein all jealous of robbie cuz hes older and
     *~*~*manlier**~*~ and thinking I BET HE HAS BODY HAIR AND STUFF
     UNLIKE ME SIG H S but then he thinks about it some more and whoop
     surprise boner tHE REST IS UP 2 U"
You know there’s more to being a man that just being physically strong. You
know that being mentally strong, that standing up for what you believe in and
keeping your ground, is just as manly being able to bench press heavy things
and having a strong grip.
Even though you know all that, it still hurts lying in your bed, thinking about
how you’re stuck in this scrawny, barely pubescent body.
Stan and Mabel said that you were your own man, but they still had made fun of
you for being weak. You don’t want to be weak. You want to be strong, tall, you
want to have more than one chest hair and you want to be treated like you can
handle yourself. Not like you need to be taken care of.
If you were physically manlier, maybe Wendy woud be with you and not Robbie.
Well, it would help if you were older too, but the manliness has to be a big
factor, girl’s like manly dudes. You don’t like to think that Wendy is the type
of girl to only care about appearances, but with such a rancid personality,
she’s gotta see something in Robbie, so you’re betting that it’s his manliness.
Your mind starts to travel, and suddenly you’re thinking about Robbie taking
off his shirt, showing off in front of you and rubbing in just how much better
he is than you. You imagine he has dark chest hair, not so much that it’s gross
but just enough to be attractive, and that his abs are nicely defined, a 6 pack
probably. His arm’s are most likely toned too, from lugging band equipment back
and forth between gigs. With all that muscle, he has to feel firm, strong, you
wonder what it would be like to touch him…
Whoa, okay, you’re getting side tracked. This isn’t the time to be comparing
yourself to Robbie. You’re getting yourself too worked up, and your stomach is
swirling uncomfortably with jealousy and something else.
Something else? Uh oh…
With a sigh, you reach down between your legs, and sure enough your crotch
tingles and you can feel the hardness. Great. You don’t know why this keeps
happening every time you think about these things, every time you start getting
jealous of Robbie. Maybe because you’re also sorta thinking about Wendy? That’s
gotta be it, you guess.
You roll over onto your side and curl yourself up into fetal position. You
should just go to sleep, you don’t want to deal with this right now. Your mood
is too sucky, and you don’t want to think about this anymore. Still, if you
don’t take care of it, you’ll wind up with a stomach ache, and that will make
you ever more miserable.
You groan and roll over onto your stomach, grabbing one of your spare pillows
and wedging to between your legs, then shimmy your pajama pants down below your
butt. You brace one arm under the pillow, holding it tight against your groin,
and bring your other arm up to your face, covering your mouth with your hand so
you have something to keep you quiet—you’d rather not risk waking up Mabel.
Once you’re all set up, you rock your hips down, grinding against the pillow.
Heat courses through you, rushing from your crotch all the way to the tips of
your fingers and toes, then settling in the pit of your stomach. You have to
bite down on your hand, it already feels so good and if you don’t you’re going
to get loud.
Deciding that you don’t want to drag this out too long, you buck your hips as
fast as you can without making the bed creak. Your breath is coming out hard
through your nose and you feel yourself starting to sweat a bit, the cool
Oregon air hitting your skin and making you shiver a little, but inside you
feel so hot. Your body feels like it’s on fire, every nerve tingling and making
you twitch. You’re already close.
You roll over onto your back, the hand that was under the pillow now wrapping
around your erection and gripping it tight. You whimper, sinking your teeth
harder into your knuckles, and start pumping yourself fast. Lightning shoots
through you, and you squeeze your eyes shut, trying to think about Wendy doing
this to you. You picture her with her shirt off, breasts small and perky but oh
so cute, smiling at you while she works her hand on you.
But just like every time you think about Wendy lately, your mind switches gears
and you’re suddenly thinking about Robbie again, even though you don’t want to.
Try as you might, you can’t get the image of him out, his rough hands jerking
you, his strong body hovering over you, his lips touching yours…
You hit your peak with a way-too-loud keen as soon as you think of him kissing
you. Every muscle in your body goes tight, then relaxes. The process repeats
rapid fire as a wave of relief washes over you, ejaculate spurting onto your
hand and stomach. You stroke yourself a few more times, riding it out until you
start shaking too much from oversensitivity, then you let go of yourself and
breathe deep while you go soft.
After a moment of just lying back and catching your breath, you push yourself
up, limbs feeling wobbly. You reach under your bed and grab the box of tissues
you keep under there, then wipe yourself off and pull your pants up so you can
head to the bathroom. In there, you wash your face with cool water and pee,
then you trudge back into the room you share with your sister.
You flop back down onto your bed, staring at your ceiling and trying your
hardest to not think about what all this means. Just like you do every night.
***** Lap Dance *****
Chapter Notes
     I don't like this one a lot because I think it's jumpy but oh well.
     It's also not as explicit as the first one so there's that too.
     The requests were both from my friend ladlekind@tumblr:
     "dipper in robbies lap hhsjshd"
     "dipper bein all kiddy and cute and nice to robbie and hugging him
     and sitting on his knee all innocent in front of wendy since she
     thinks theyre friends now bUT HES JUST TRYIN TO MAKE ROBBIE HORNY OH
     NO"
The whole “hating each other in silence” pact you made with Robbie actually
worked out pretty well. The two of you hung out together with Wendy, joked
around with each other, had fun, and now you guys are actually pretty good
friends. Even after Wendy broke up with Robbie, the three of you still stayed
close, which was nice. The surprising thing is that even though Wendy is
single, you don’t really think you like her like that anymore, and haven’t
tried to put any moves on her.
Actually, you think you might like Robbie now instead, and you kinda want to
put the moves on him.
This would be weird, you think, realizing that you have a crush on a guy that
most would assume only likes girls. Luckily for you though, it’s not weird,
mostly because you think he might like you back. He’s really touchy with you,
always putting his arm around you when you sit next to each other on the couch,
playing with your hair and tucking it behind your ears, stuff like that. That’s
the kind of stuff people do when they like someone, right?
You decide to find out the best way you know how—logically thinking up a plan
and writing out a list of steps.
The first step is to see how he responds to affection. Robbie comes over to
your place after you and Wendy are done working at the Shack, and when he
arrives you give him a big, unannounced hug to greet him. You throw your arms
around his middle, squeezing him and burying your face into his sweatshirt
which actually smells pretty nice, like a mix of Axe and cigarette smoke.
“Whoa, hey there little man, happy to see me?” he asks as he wraps an arm
around you, ruffling your hair with his other hand. You look up at him and he’s
smiling, not seeming to mind at all that you just randomly hugged him.
“Yeah, I guess I kinda missed you.” You take his hand and drag him into your
living room. Once again, he doesn’t mind the contact, and actually gives your
hand a squeeze. That’s a very good sign, you think.
Wendy looks up from her magazine, then gets up off the couch to greet Robbie
herself. She gives him a “Hey man, how’s it hanging?” and fist bumps him, then
sits back down. He doesn’t hug her, just nods and answers her question, then
follows her to the couch, planting himself in the middle.
Now it’s your turn to sit, and you could take your usual spot on the other side
of Robbie, but you think now would be a good time to start on Step Two of your
plan: seeing if you can get him to pay more attention to you than to Wendy. You
do this by seating yourself squarely in Robbie’s lap.
Wendy doesn’t react, she doesn’t really find anything weird. Robbie, on the
other hand, looks down at you questioningly with one eyebrow raised. He doesn’t
seem mad though, so you smile up at him innocently and shrug, leaning back
against his chest. He shrugs too, and snakes his arms around you, holding onto
you as Wendy starts telling a story.
“Oh dudes, I wanna tell you, me and Tambry went to this show last night, right?
It was kinda lame, but there was this guy there, and…”
You don’t pay too much attention to her, just nodding along whenever you think
it’s appropriate. Instead, you focus on getting Robbie’s attention, placing
your hands on top of his and stroking the backs of them with your thumbs. This
gets him to start moving his own thumbs, rubbing little circles on your
stomach. That could just be an involuntary response though, so you decide to up
the ante.
You squirm around in his lap a little, under the guise of trying to get more
comfortable, and you hear his breath hitch behind you. You feel him shift to
look down at you, but you don’t look back up at him, not yet anyway. You don’t
want to give away your plan.
You switch your positioning, turning in his lap so that you can face Wendy and
lean against him, placing one hand on his chest. You don’t stop moving your
hips, gyrating them as unnoticeably as possible, which you think you’re pulling
off because Wendy keeps telling her story.
“So the guy’s like, ‘I bet I could eat five pies in a row,’ and me and Tambry
are like, ‘No way dude, you’ll explode!’ But he goes and buys the pies anyway…”
Robbie is starting to get antsy, you can feel him starting to squirm, his dick
starting to get hard under your butt. He looks down at you a few times, and one
time you actually do decide to look back at him. His face is red, mouth parted
slightly and panting softly. Your own shorts are starting to feel a little
tight, so it’s time to implement Step Three: find out if you can get worked up
enough to run off with you.
Wendy is still going on about that guy and the pies, talking animatedly and not
really looking at either of you, so you’re pretty sure you can get away with
this. You lid your eyes as you look up at him, grinning softly and licking your
lips as you grind down particularly hard into his lap. His eyes fall shut and
he lets out a breathy groan, which causes Wendy to pause.
“Uh, Rob? You okay there man?”
His eyes snap to her and you feel him tense up nervously, but he clears his
throat and manages to keep his voice steady when he answers her.
“Yeah dude, I’m fine. Just uh…hey, hold that thought for a second. I gotta run
to the john real quick.” Robbie lifts you up out of his lap and sets you down
next to him, then adjusts the obvious bulge in his jeans and disappears down
the hall. Now’s your chance to go after him, so you hop off the couch and
excuse yourself, too.
“I think I gotta go too, so I’m gonna go use the other bathroom! Sorry for
interrupting your story, Wendy.”
“Uh huh,” she says, giving you a knowing look. ”Go get ‘em, tiger.”
You blink, not getting what she means at first, but then it hits you that she
must have known what was going on the whole time. Of course she did. Wendy may
act passive, but she’s not stupid.
You blush, looking down at your hands, then laugh awkwardly. ”Hah, um, thanks…”
She smiles at you and wishes you good luck, and you scurry out of her sight and
after Robbie.
You deem your plan a success when you see him standing outside the bathroom,
grabbing you and pulling you close for a hard kiss.
***** It's Not Pee *****
Chapter Notes
     THIS ONE IS REALLY PORNOGRAPHIC AND VERY SHOTA!!!!! YOU HAVE BEEN
     WARNED!!!!!
     Dipper gets a blowjob and thinks he's gonna piss himself.
     Request was, again, from ladlekind@tumblr.
     "'spookyshaming said: when shotas are about to come they think they
     have to pee'. this w/ dipperobbie"
His mouth is wrapped tight around your penis, sucking it hard and making it
throb. You can feel his tongue against you, sliding up and down the underside
every time he bobs his head. He moans when you do, and you swear the vibrations
of his voice go through your whole body. You’re so hot, but it’s a good kind of
hot that you never want to stop feeling. You’ve never felt so good in your
life.
But then something changes, and suddenly you feel like you have to pee. Like,
right now.
“Rob,” you whimper. ”Robbie, p-please, I think you need to stop, I need to go
to the b-bathroom!”
He does stop, but he replaces his mouth with his hand, stroking it fast as he
climbs on top of you.
“Don’t worry, Dips, you’re not gonna piss. Trust me. Just relax and come for
me, babe…”
Before you can ask what that means, he kisses you, tongue slipping into your
mouth and curling with your own. You can taste yourself on him, which you
thought would be kinda gross, but it’s not. It’s actually making you hotter,
your tummy and balls suddenly getting really tight.
Crap, you are seriously about to pee yourself. You push his shoulder and break
the kiss to warn him.
“Robbie seriously, I’m gonna—ahhhhh!”
You start shaking all over and your hips buck into his hand. You feel
absolutely amazing, your whole body lighting up and pulsing with pleasure.
It quickly fades though when you feel the wetness dripping down the sides of
your erection.
“Oh… Oh no, Robbie, I’m so sorry, I told you I was—!” You cut yourself off with
an embarrassed groan, covering your bright red face with your hands. You’ve
gone from feeling incredible to feeling like you want to curl up and die in
seconds flat.
Robbie moves your hands away from your face, and you wonder if he’s going to
get mad at you for peeing on him, but he’s smiling.
“Babe, relax. It’s not pee.”
You give him a confused look. ”But…if it’s not, then what—”
“It’s cum. It comes out when you orgasm, which is what just happened. Here,
look.”
He brings his hand up to show you, and he’s right, that doesn’t look like pee
at all. It’s thick, kinda white and translucid. Huh.
He starts licking one of his fingers, and you must make a scandalized face,
because he laughs and runs his clean hand through your hair. ”It’s fine,” he
says. ”It tastes good.”
You don’t really believe him, so you grab his wrist and lick the rest of his
hand clean to try it. It doesn’t taste good, but the look on Robbie’s face
means that you must have done something good.
“Okay, that was really hot, Dips.” You blush, biting your lip. You like when he
calls you hot.
He takes your hand and brings it between his legs, placing it on the hard lump
in his jeans. ”I think it needs to be my turn now.”
You are more than happy to oblige.
