"I'm not sure I like this idea..."
Dipper mumbles looking at his feet. Having a relationship with a demon is
pretty hard in itself, but when the obvious craving for contact, intimate and
physical, shows up... Let's say one has to be creative.
"I'm listening, but I'm not hearing any other ideas coming out that pretty
mouth of yours!"
Bill was cupping his tiny hand on a nonexistent ear, and the human couldn't
help but shoot him an annoyed look, but ultimately lying down on the copier
none the less: even if he hates to admit it, the demon is right, it's the least
disturbing option anyway. It's almost intimate, pushing that button, but in a
moment it's already over and the machine is violently printing. For a second
there Dipper hopes it won't work, it's scary in its own weird way to do stuff
with a body exactly like his own given he has a twin sister and all... But as
long as he doesn't think about it too much, everything is cool. Plus, he's
doing this for Bill, and he's so excited about this, so excited in fact that he
leaves no time for explanations to "Tyrone"... He just forces his way in and is
now stretching his arms with a certain curiosity over the possibly familiar-
but-not-quite sensation. He must've found some loophole around the fact that
it's technically not a human, or so Dipper likes to think, but seeing that
toothy grin makes him feel better about the whole thing.
"Whoah I forgot how short you are!"
Shut up, you are literally a triangle, he would've replied if only Tyrone...
Bill... Bipper... Whatever would stop trying to climb up the copier and
possibly manage to hurt himself in the process, and the first reaction to this
view is of the fight or flight kind.
"Hey hey hey hands off! At least let me get dow-"
Too late, Bill caught the neckline of his shirt and tugged him close already,
plastering on his lips a kiss made of teeth and grins. It doesn't take long to
melt in that gesture, and it's great having a mouth to kiss, a body to cling
to, and it looks like the demon thinks so too, judging by the frenzy of his
hands on him. Slowly, carefully, Dipper guides himself off the machine, lest it
breaks, to be at his same level. To kiss him better, to touch him better, to
feel... Feel that strange idea coming true and not in an entirely unpleasant
way.
The jacket is the first victim, falling to the floor with only a whisper, and
then with the shirt the cap gets caught in the neckline and flies off along.
Normally he'd feel explosed, but not this time. It IS awfully embarrassing, but
he understand how Bill is completely swept off his feet from the sensory
overload of "his" "new" body. In between kisses, the human is smiling along. As
long as he doesn't think too much that he's touching himself, it works. It's
Bill. He can touch him, and kiss him, and feel his breath and sometimes that is
enough. Still, when his-not-his fingers come to play along the rim of his
pants, he takes a step back.
"Wait... here?"
"Would you rather go upstairs with Shooting Star to let her watch?"
Fine. Seems like Bill didn't lose his sass even in the heat of the moment. He
lets the demon drag him down on the floor of the dusty back room, the only
thing separating them from getting a kneeful of splinters being the sheet that
had been covering the copier, and Bill is right over him, yellow eyes full of
curiosity as he showers the human in kisses... And more kisses... Strange,
Dipper had often imagined this moment, and he always pictured him going right
for it without hesitation, he even feared they would end up taking things too
hastily and... Something feels off.
"Is everything okay?"
He whispers between those lips that are and aren't his own.
"Just peachy!"
Dipper masks a smile with an unconvincing grimace.
"Say... when was the last time you did... well... this?"
Bill's head falls heavily atop the boy's bare chest. For a second there, he has
trouble understanding the implications.
"Uh-Oh."
Dipper whispers circling the other's waist, nuzzling the crane of his neck. It
looks like he'll need to overcome shyness for this one and take the matters in
his own hands... okay, deep breath, it's not that hard. It's not that hard.
It's an awkward position for this kind of situation, but he doesn't want to
embarrass Bill further or make him feel like he's not in control so he settles
to make it work somehow. There was a playful rivalry between them, sure, but
teasing him on that would be taking it too far. His legs splay apart as he
arches his lower back towards the other's groin, rubbing against him, and
places chaste kisses on his neck, trailing his hands on the other's back to
reveal some skin. The demon seems to respond to that, pressing back and moving
with him, soon recognizing what causes pleasure. In a way it was unreal, having
seen Bill so vulnerable, and yet there he is, face buried in his shoulder,
slowly starting to take control again. His hands roam onto his body, settling
on the zipper of his pants to open them despite the clumsiness of disuse, and
opens up his own to match.
Things are starting to get heated, and Dipper feels a little less
uncomfortable, a bit less intimidated about touching a being of pure energy
incapsulated in a semi-human vessel. Instead, Bill seem to be the more
sensitive of the two this time, possibly overwhelmed by the experience of an
actual human body and its completely different sensibility if compared to the
mindscape shape he had kept for... who knows how long...
"Dipper..."
His voice is low and husky, whispered into his ear as he explores the secrets
and crevices of Dipper’s body, and the human lets him, showing no fear of
sighing and moaning and breathing out encouragements to assure him that yes,
everything was going great. Slowly, Bill is starting to unwind as well, palming
the clothed lenght and exploring the outer shape before reaching for the
elastic band and uncovering the secret. For this time, he seems uninterested in
his own pleasure, and the boy doesn't press the matter, preferring to let him
do and whisper his name as the best shivers he ever experienced since he came
to gravity falls make their way down his back. Biting his lip he dares a glance
towards the demon, but soon enough his eyes roll back in bliss and his voice
raises, completely inebriated by the movements of his lover's hands and those
kisses that fall on his skin like confetti, rolling on his chest and clavicles
and navel... covering every inch of his boiling skin.
Each pump of his hand sends his whole system crazy, and he starts to rock his
hips in time, gasping and clutching at his double's shirt in a vague attempt to
steady his unresting limbs into place. His whole body arches up needingly,
shoulders and feet leveraging against the floor to press up and ask for more,
his hands digging in the other's neck and cheeks driving his face closer to
lock lips, breathing out in between kisses. He is almost feeling his thoughts
bid farewell to his mind, leaving only lust and need in their place, and he
doesn't fight it, unwilling to hold back. The boy clenches his jaw, clutching
Bill close as he spasms and comes and his hand shakily reach down.
"S-Stop... ah-"
His voice hitches at another, slower, pump from his partner. Not entirely
unpleasant, but he's too sensitive right now to go on and thankfully Bill seems
to understand, maybe remember, as his eyes widen. He eases his grip, and Dipper
slumps down onto the floor, a layer of sweat beading on his forehead that the
demon kisses before settling to his side. Dipper wouldn't have imagined, not
even in his wildest dreams, that he would end up like this. Still, that is
somehow too part of Gravity Falls... Part of them. He lazily spies the other
with half lidded eyes, and for a second there he swore he saw him hide a smile.
 
End Notes
     I had a completely different idea at first, but still.
     If I get the occasion I would love to write some Tyrone/Dipper, who
     wants some selfcest?
     By the by, feel free to prompt me!
