     aRE YOU HAPPY LANX
See the end of the work for more notes
Wendy was right, being a teenager was the absolute worse. Somehow he had
started feeling even more awkward and sweaty than before, and he didn’t even
think that was scientifically possible. Might explain why he was so damn
thirsty all the time. He knew things from tv, and apparently grunkle Stan had
told him all about the birds and the bees, what that confusing metaphor was
about but Dipper honestly couldn’t remember. Probably another one of the old
man’s memory lapses. He knew, and would scoff and roll his eyes about it but
never really thought he would ever actually be the type of person who would
nervously chew on his lip in the dead of night with the laptop perched closely
in his lap while he stared wide eyed at the search engine.
He was thankful that Mabel had decided to go over to Candy’s for a sleepover
leaving him to have their shared room all to himself for the night. His worried
gaze flickered over to the door and then back at the bright laptop screen and
back before he squeezed his eyes shut. Quickly typing out the first word for
what he was trying to look for as vaguely as he possibly could. He got the
first word down and hit the ‘r’ button before he slammed the computer shut far
louder than he was hoping for.
“I can’t do this!” He whined aloud to himself and shoved the now closed laptop
off of his lap and onto the bed before he curled up. He chewed on his lip and
ran his fingers through his bangs, the heel of his palm brushing against his
heated forehead.
He knew what he needed to do. Well, he didn’t needto but trying to just sleep
his hormones off was harder than it sounded. It all hit him like a kick to the
teeth. And when he did actually manage to sleep they weaseled their way into
his unconsciousness. Which always made him wake up with a pink dusting his
cheeks and caused him to roll over onto his side and bury his face into the
pillow or blanket. Even using his imagination got him embarrassed and
flustered, his paranoia spiking and fearing that someone somewhere could get
into his head and know what it was he was thinking of. Think of him as a huge
pervert…
He brought his knees up to his chest at some point and hugged his arms around
them to bury his face. He was getting desperate, and he wasn’t the only one who
knew that. Bill knew… He wasn’t much of a threat anymore, or at least not at
the moment. But he was still as annoying as ever, popping in and out just to
bug Dipper. He always told him it was because he was bored, or he pitied his
loneliness, it was usually some new excuse every time. Dipper wasn’t sure
though if Bill bothered the others or not, but preferred to believe that he
didn’t. He didn’t know why though.
“You’re crying again,” a voice cut through Dipper’s hazed thoughts and he
looked up and around the room to see no one, “In your head, kid.”
Dipper sighed, “I’m not crying. Just, what are you doing here.”
“Told you a billion and four times before but I suppose I’ll tell you again,”
Dipper heard footsteps echo in his head and pounded at his temples, God he
hated when Bill did that just to annoy him. Carefully the triangular form of
the demon appeared in front of him and caused him to instinctively lean away
from him. It gave Bill the perfect place to sit on his kneecap, “I’m a dream
demon. Keyword; dream. Meaning if you’re not asleep, I can’t do my job.
Although, I do gotta say. When you areasleep, your recent dreams have been
pretty messed up lately. I mean really, you need help.”
Dipper groaned, of course he would say something, “No shit Sherlock.”
“Hey! A kid your age shouldn’t be using such a foul language,” the demon
pointed his cane at him, Dipper leaning back and going cross-eyed as he stared
at the tip just an inch or so away from the tip of his nose. Bill sighed and
dropped the cane entirely and before it hit anything it disappeared into
nothing, “Seriously, kid, you should do something about it. I mean if you wanna
get off, get off. If you don’t your dreams are just gonna keep getting more and
more persistent,” he looked at his nonexistent fingernails nonchalantly, “I
mean, like I said I’m a dream demon, and I could fix all of your problems.”
“You can?” Dipper perked up, he shouldn’t have shown any interst in what the
demon was saying but he couldn’t help it.
“Of course I can! For a price,” Bill’s near cat-like pupil shifted to look at
the human. Dipper scowled, “Aw, don’t give me that look, you don’t even know
what I was gonna ask for!”
“I’m not making any deals with you-“
“Hey, I never said a deal! I said price, and that could mean anything!”
Dipper sighed and huffed, leaning back against the headboard and folded his
arms sternly over his chest, “Bill, just get lost.”
“How can I get lost when I know everything, including directions?” the demon
spoke cheekily, and the mortal of the two rolled his eyes at the comment, “And
besides, I don’t want to. I want you to do something about your gross dreams so
I can get back to screwing with your head.”
“When you put it like that I don’t want to.”
“Okay, but like I said, hear me out. The longer you wait the worse it’s gonna
get, you can ignore it all you want but hormones are monsters and will make
your life miserable!” He noticed how Dipper’s eyes narrowed in on him, and
before he could form the question on his tongue Bill raised his hands and
answered his unspoken words, “Yeesh, look, I know a thing or twelve about
humans and hormones, you know I do the whole possession thing with plenty of
people. Not to mention a few other things that have nothing to do with you.”
Dipper’s scowl slowly turned into a pout of frustration after a minute, he was
so exhausted and Bill was annoying but what could he truly do? He looked over
to the floor and felt the demon’s cane tap at his cheek to catch his attention,
“Hey, kid, no pouting. It’s gross.”
“Bill,” Dipper started but of course the demon had to butt in with some dumb
comment.
“Would you hear that, you said my name without any anger or annoyance, you
should do that more often. Sounds nice.”
He rolled his eyes and sighed for what had to be the several thousandth time in
the past hour, “Does it really get worse?”
“What? Hormones? Oh yeah! First you can’t sleep, and then when you’re around
people you feel uncomfortable, your mind wont stop thinking about all that
sweaty gross stuff humans do! And next thing you know you’re embarrassing
yourself in front of everyone all because you didn’t get off!”
“That’s awfully specific…” Dipper raised an eyebrow at him.
Bill crossed his legs and snapped his fingers together before pointing at the
other, “Hey! I just thought of something! Is the reason you wont get off is
because you don’t know how?”
“What kind of question is that?!”
“Your reaction is making me think that I’m right,” he sat back and folded his
arms, a smug look took to his features.
Dipper sighed, why the hell was he even talking to a triangle about this?! He
didn’t know… “I know how… I just, think it’s gross… Only weirdos and creeps do
that…”
“Says who? Everyone gets off! Guys, girls-“
“Girls..?”
“Oh yeah! If not more than guys! You humans have a weird conception of how
girls are complete prudes, but if you could just see what they dream of and
what they think of. I mean that redhead chick? Oh ma-“
“Bill! I don’t wanna hear it!” Dipper’s face flushed red at the words and
refused to even think about that.
”Okay, okay, okay, don’t have an aneurism at your age,” Bill rolled his eye,
“Look, Pine Tree, say what you will about creeps and weirdos. If you don’t
wanna do it, than how about someone else does?”
Dipper looked at the demon on his knee with wide eyes, he was confused and
worried, and dare he admit intrigued, “What… What do you mean?”
“Aw, where did that spark of annoyance go? You sound like a puppy,” if Bill had
a mouth, or rather if his mouth were visible in the moment it would be holding
a wicked smile as he eyed Dipper, “It’s cute, really. Anyway, what I mean is if
you don’t want to get off by yourself, then let someone else do it. That
someone else being me.”
Instead of yelling a no or some profanity Dipper simply swallowed and watched
the way the demon seemed to impatiently tap his foot in the air as he waited
for him to speak, “What… Why-“
“Am I being so blunt? Because I’m tired of not being able to play around in
your dreamscape, honestly those wet dreams annoy me and I’d rather not deal
with them. So you do this, we do this, and those dreams can buzz off until your
teenager horniness comes back and I have to either A.) wait for you to suck it
up and jerk it, or B.) I come back, pester you, we have some banter, and then I
do my thing and boom! You’re out like a baby and dream of sweet things like
ponies and rainbows until I get back into that head of yours and have some
chaotic fun. Besides! You’ll love it!”
Bill’s words seemed to go a mile a minute just for the sake so Dipper wouldn’t
be able to fully register them, it seemed like the kid was actually considering
it all. His voice tumbled out of his throat and over his tongue, “What.. What
do you want in return, the price?”
“Nothing! Ab-so-lute-ly nothing! What do you say? Wont even need to shake on
it, just tell me the okay, give me the green light, and I’ll make you feel as
wonderfully blissful as a human could ever feel!” Bill leaned forwards a bit,
his eye lidding and pupil narrowing, his voice even dropped almost threatening
to Dipper, “What do you say?”
Dipper stared at the demon in front of him, his own eyes wide and searching for
some sort of lie in that narrowed pupil. Perhaps he forgot the entire form the
being took was drenched in deceit because he couldn’t find what he was looking
for in his eye, lost like a glass of water in the middle of the ocean. He
swallowed thickly and felt his gut twist, but he wasn’t entirely sure with
what.
“O-okay.”
Bill’s eye flashed happily as he sat back with a laugh, “Perfect! Now just do
as I say, got it?”
The human didn’t say anything but dropped his legs when he the demon’s small
black hand smacked his knee and snapped his fingers before pointing downwards.
Bill didn’t bother floating as he stepped carefully up the other’s thighs with
his arms folded across his form. Dipper’s face flushed as he watched him nudge
the front of his pajamas with his foot.
“B-bill, do you even know what you’re doing..?”
“Of course I do!” Bill looked up at him with a near offended look, “If I didn’t
know what I was doing then why would I bother to help you out?”
Dipper sighed and gave a weak shrug.
Bill simply nodded and moved to sit down in his lap, lacing his fingers
together before cracking them and then shaking his wrists to get started.
Dipper was already more embarrassed then he ever was before in his entire life
he felt like. Instead of watching him he leaned back on his palms and stared
somewhere else, anywhere else. Bill didn’t mind nor care, simply resting both
his hands against the mortal’s crotch and kneading his hands in a manner that
reminded Dipper of a cat. Even though his hands were small, Bill’s movements
were still rather effective and noticeable. The way he would move from kneading
with his palm to moving his fingers in circles. Dipper’s fingers curled into
the bedsheets and he chewed his lip, bending his left leg and running the flat
of his foot against his right.
“Geez, kid, didn’t realize just how desperate you were,” Bill made the
nonchalant comment that Dipper didn’t have it in him to even retort to. But he
did look down with curiosity when he felt Bill move away and push up his shirt
as much as his short arms would allow him, “Take it off and lay completely
back,” just as Dipper opened his mouth Bill cut him off with a point of his
finger, “Not a word from you, just remember, do what I say.”
Dipper closed his mouth and ran his teeth over his bottom lip before he took
the bottom of his grey t-shirt and pulled it over his head, tossing it off to
the side once he was done. Scooting down just enough so he could lay down on
his back he covered his chest with his arms and stared worriedly up at the
ceiling. He didn’t hear or feel anything for a moment until he saw Bill
floating above him and staring at him with a blank and bordering annoyed
expression.
“I recall saying take your shirt off and to lay back, nothing about you
covering your chest,” Bill rolled his eye and placed his hands on his sides,
“Why are you even doing that, it’s not like you’re a female and have breasts or
something.”
“It’s embarrassing!” Dipper only tightened his hold around his chest more so.
“Kid, you go shirtless all the time, at the pool and sometimes just because its
hot or you’re too lazy to put on a shirt.”
“But-“
“But nothing! It’s not embarrassing because it’s just you, and me. At the pool
it’s a bunch of strangers, at home it’s your sister and grunkle, and
occasionally to your dismay Star’s weird friends.”
“It’s weird because you wont shut up and are making it weird!”
“I’m just pointing out the facts kid, besides I’ve seen you topless plenty of
times, not to mention naked.”
Dipper’s eyes widened and his face flushed, “What..!?”
“Don’t flatter yourself, you’re not the only and you’re not the first nor last
flesh suit I’ve seen naked,” Bill lowered himself until he was sitting just
below where the other’s arms were folded, he pushed and pried at them, “Now,
move them.”
“Why do you even-“
“What did I say, do as I say,” he heard Dipper groan a whine and reluctantly
move his arms to lay stiffly at his sides, Bill praised him and ran his hands
over his smooth chest, “There you go.”
Dipper was pouting, and Bill took note but didn’t say anything. Instead he
continued to run his hands over his chest before he crawled over and gave a
single flick to one of the boy’s nipples. Instantly Dipper lifted his head and
stared wide eyed at him.
“What the hell are you doing!?”
Bill didn’t even look at him as he continued to toy with the nub, more rubbing
than anything else, “Don’t think too much about it, human’s do this all the
time. It’s an erogenous zone.”
“A what?”
“Feels good.”
Dipper continued to sit up on his elbows and worrying his lip, looking at the
wall to his left rather than at the demon. Bill continued to rub his hand over
before roughly pinching and tugging at the nipple, getting Dipper to hiss
through his teeth and squeeze his eyes shut, his face a deep crimson and his
hands holding a death grip on the sheets.
“You act like you’ve never touched yourself here.”
“Because I haven’t! That’s weird! Who touches their nipples,” Dipper opened his
eyes and stared down at Bill, “Besides, dumb kids do that painful purple nurple
thing.”
“Tiddy Twister.”
“And seeing how I’ve had my fair share, excuse me for not wanting to play with
my chest,” his expression wasn’t so much of anger as it was embarrassment and
slight confusion.
But Bill had switched from the painful tugs and pinches to once again carefully
rubbing and kneading at his nipples instead, his gaze flickering from his hand-
work to the human, “Okay, alright, do you want me to stop then?”
“Kinda, yeah, stop.”
A surprise would’ve been an understatement to Dipper when Bill pulled his hands
back entirely and moved on. Bill hummed to himself in thought, there wasn’t
much he could do without a mouth, and sure he could conjure stuff but he wasn’t
up to that right now. No, for once he didn’t want to scare the boy. That left
him with only his hands. Hands that he wandered around Dipper’s chest and
stomach just to touch him. He spun around on his stomach and moved to the hem
of his pajamas, going back to kneading and palming the front of them.
“Alright, this is boring, take them off,” Bill flopped back onto Dipper’s
stomach, crossing his arms as he stared up at the ceiling in boredom before
looking up at the other. He raised a hand and snapped twice, “Hey, kid, listen.
Take them off.”
“No need to be so pushy,” Dipper whispered and pushed Bill off to the side so
he could sit up on his tailbone and shimmy out of his pajamas. Just as he was
about to lay back Bill piped up.
“Underwear too!”
Dipper was hesitant but did so. Once he was fully naked he laid back and before
he could cross his legs Bill crawled up and sat on his lower abdomen. He rubbed
his hands together before reaching a hand out and running his fingers along the
mortal’s arousal, hearing his breath hitch behind him. Moving to have both
hands on either side he moved his hands rhythmically up and all the way down to
the base. Dipper took to squeezing his eyes shut, eyebrows knitted as he
focused on the touches. The touches… Who was touching him… Bill. He whined
quietly in his throat and did his best to focus on his thoughts, imagine
something, someone else, and anyone else. He didn’t care.
Bill’s hands didn’t let up but he eyed the human with a narrowed pupil before
closing his eye and holding back a sigh. He squeezed his hands around the base
of the mortal’s dick before he roughly brought his hands upwards, getting a
quiet whined moan. He twisted his hand movements as he continued to move them
upwards and back. Enjoying every small noise that Dipper made behind him.
“Pine Tree, say my name.”
He wasn’t sure if Dipper heard him or just decided to ignore him, but he didn’t
press further. Instead he moved a hand away and rubbed circles along the base
of his shaft before pulling entirely away. Dipper opening his eyes tiredly and
giving a confused look.
“You said, you were gonna help me,” his voice came out small and quiet, not
like he would’ve wished but he honestly didn’t care at the moment.
Bill hummed and floated a little bit, “Relax, I am. Now hush.”
He moved higher to think, positive the human didn’t have what he needed. Not
like he actually needed it though so he shrugged and moved on. Dipper had laid
back again and waited, but he continued to watch the demon. Bill moved so he
was above Dipper’s arousal and reached down to position himself, moving so the
tip was along his underside.
“W-wait, Bill, what are you doing?” Dipper sat up again and looked at him.
“Relax, I said I was helping you,” Bill waved him off.
Dipper laid back, watching as he worried his lip. He thought Bill was just
gonna jack him off truthfully. But he swallowed and nodded, “Okay…”
Bill didn’t say anything while he lowered himself on the other, it didn’t take
long if any time at all before he was comfortably seated in his lap with his
entire length inside of him. Dipper mewled at the feeling around his dick, it
was warm and it sent tingles all the way up his spine. His blunt nails
scratched the fabric of the sheets in his hands when he felt Bill ‘pulse’
around him. The demon stared at him watching him before deciding he had waited
for the other to get used to the feeling before he pushed his hands against him
and lifted himself up. He watched every expression on Dipper’s face.
“O-oh God,” Dipper whispered at the feeling. It wasn’t anything he had felt
before, and was nothing like he had expected it to feel like. It felt great.
Every time Bill would lift himself up Dipper would whine, and when he dropped
back down he would moan quietly. The demon’s insides- did he even have insides?
Whatever it was felt as though it was coiling around him, like a tendril or
another hand even pumping along his length. It was warm and felt almost static
like, but nothing painful like pins and needles. The fact that he could
actually feel how it felt wet and slick made his face flush down his neck and
ears, but it made wonderful friction every downward grind Bill gave. Bill knew
this too. He watched the way the human’s jaw twitched and trembled, his throat
bobbing as he swallowed. Listening to the soft whines and mewls, gasps and
moans. His fingers dug into his flesh with determination to hear his name fall
with bliss from the boy’s lips.
“Hnn-fffua-ah,” Dipper wasn’t sure if he was even trying to say something as he
whined, feeling the demon tighten around him almost painfully before letting up
just enough to keep a pleasant pressure around his dick.
He felt his stomach knot and tighten, eyes widening in confusion and bringing a
hand up to hold at his abdomen, “I-is, is this, supposed to fe-el like thi-is?”
“Hm?” the demon stopped.
“My st-omche feels, tight,” he looked at Bill with knitted eyebrows and wide
worried eyes laced with confusion, “And we-weird…”
Bill hummed, “Its suppose to feel like that, means you’re going to cum. I’ll
let you, but…”
“But?”
“Only if.”
“If?” Dipper looked as though he was going to cry.
“Say my name?”
He looked at the triangle in his lap and then he blinked in thought before
looking at him again, “Bill..?”
Bill sighed almost contently… That’ll do. Carefully he lifted himself up again
and picked up his lost pace of dropping himself down on the human’s member.
Feeling his muscles tighten under his fingertips letting him know just how
close he really was. The tight coil around him twisted and pumped faster,
Dipper dropping his head back as he moan the demon’s name wantonly. It made
Bill’s eye flash before a prideful flutter settled in the pit of his form- he
wasn’t sure if he actually had a heart. Not anymore.
“Louder for me, Sapling,” Bill encouraged.
“B-bill..!”
“Good, but you can do better.”
“Biilll.”
“So close.”
Dipper squeezed his eyes shut and whined loud enough between the two of them,
“Bill, Bill ple-ease, it hurts, and, and it’s hot, and ple-ease, Bill please!”
Bill had a smug impression to him and pushed himself up on his hands and ground
down a handful of times before the young mortal came. A loud whined moan
falling from his lips.
“B-bill, oh God, Billl-aAahhnn,” Dipper’s head fell back as he mewled, the knot
in his stomach finally unwinding as a blissful wave of pleasure washed over
him.
Bill rubbed the boy’s lower abdomen as he stilled, sitting in his lap even
after he was finished. After some time had passed and he grew tired of watching
the other’s chest rise and fall he spoke up and broke the silence, “Geez, you
haven’t even watched porn and yet you sound just like the drugged up actresses
staring in them.”
Dipper didn’t say anything and swallowed. Bill watched and sighed, finally
climbing off of him and was left with a cold shudder. He floated in place as he
dusted himself off, as if he needed to. What he truly needed was a bath. He was
caught straightening his tie when he felt warm and clammy hands grab him
tightly and suddenly yanked him down close. Dipper smooshing his lips against
the demon’s side and wrapping his arms tightly around him.
“Heyheyheyhey-HEY!”
Dipper’s eyes fluttered at the loud yell and instantly unlatched his arms, he
pursed his lips and cleared his throat, “Forgot who you were for a second.”
That was bullshit and both knew it.
“Whatever, I believe a thank you is in order, you know, for helping you out,”
Bill waited for Dipper to speak up.
“Fine, thanks, I shouldn’t even be thanking you since I would’ve gotten off
eventually-“
“Eventually, exactly. Better now than later, because now I can get back to my
duty making you wake up crying and shaking in fear. So shut up, no more
talking, get the blankets over you and get snoozing,” Dipper rolled his eyes
and debated on getting dressed again, Bill sighed in annoyance and snapped his
fingers, the human once again clothed and covered in the layers of blankets.
Just as he was about to disappear to do true to his words, he leaned down and
titled his top hat, “And you’re welcome.”
