Summary
     At the end of the battle that day, Dipper has a very happy master to
     satisfy and Bill's ready to reward his sweet little Queen of the
     chessboard.
Notes
     So, a bit of background, since this does belong to an AU I’m working
     on (with a long fic aahaahhaha): Dipper’s a witch. He pledged himself
     to Bill. They’re in an established BDSM relationship (master/pet).
     They fight against other people.
     I don’t know exactly where in the timeline this takes place, so
     Dipper’s between fourteen and sixteen.
     The rest would be spoilers~
See the end of the work for more notes
They’re back in his room, and Dipper’s feeling impatient, earlier promises
echoing through his minde (if we win, I’ll fuck you through the mattress until
you pass out, my little sapling). Bill’s not even done with closing and locking
the door before Dipper’s on him, making small needy sounds and tiptoeing to get
to Bill’s jaw and pepper it with kisses. Bill grunts with the small impact and
laughs openly, turning them around until Dipper’s back hit the wall.
Then Bill’s mouth smashes into Dipper’s, teeth clattering like broken glass.
Dipper moans, answers just as passionately, letting the demon’s tongue enter
his mouth, lick his lips and caress the inside of his cheeks. He can’t breathe
- this is too much, too soon. The battle still sings inside him, magic wild and
bristling, ready to fire as soon as he spots an enemy.
Bill takes advantage of his restlessness, and chuckles, his voice a low sound
that sends shivers running along Dipper’s back.
 
“Oh, Pine Tree, Pine Tree…”
 
Dipper doesn’t answer to the murmur against his skin, simply bare his throat to
let Bill do what he wants - what theywant. “The desire of your god is yours
too” repeats inside his head, a mantra that makes him wants to moan again as
Bill bites hard, licks the blood running freely on the white skin.
 
“Bill…” He whispers. He’s not sure he wants to ask to stop or for more. His
mind is buzzing like a hive full of insects crawling inside his brain. He tries
to put his hands on Bill’s, to stop him (help him?) from opening his shirt’s
first button, but Bill takes his wrists in one hand, and firmly slams them
above his head.
 
“Now, Pine Tree, you have to be nice. I’m only trying to make you feel good
after this difficult battle.”
“Bill don”t -”
“Hush kid.”
 
He’s kissed again, lips claiming his own roughly, teeth biting, tongue
invading. He feels dizzy, wants to stop and breathe, but his magic purrs
against his skin as Bill (finally) puts his hand (warm, so, so warm) on the
bare skin of his chest.
 
“Do you know what I want to do to you, my sweet Pine Tree?” Bill whispers
against his lips, barely touching but still very much present, dominating
everything. Dipper feels small, cowering from the presence of his god, of the
demon he pledged himself to. He needs - he’s not sure, something anything.
He tries to speak - to say what? He doesn’t know - but Bill cuts him off before
he gets more than the beginning of his name, bites his throat again and
somehow, this feels good, fire warming up inside his belly.
 
When Bill looks at him again, there’s - oh god, is that flesh? - something on
his mouth. It should feel gross, it should make Dipper scared - more scared -
but it doesn’t and he whines until Bill laughs openly and kisses him again,
sharing whatever he bit off from Dipper’s neck. It tastes wrong, better than
it’s supposed to, iron and something else, (sugar, death and magic).
 
“You were so good outside, on the field. You were glowing, the queen of the
chessboard. Oh my dear. I wanted to take you away from them, to get you on your
knees, serving me as you should - do you want that my sweet?” Dipper can’t
answer, has stopped breathing because yeah, yeah he would love that and he
can’t help nodding, eyes wide and full of unshed tears. Bill’s eyes glow red
for a second, victory in his voice as he continues, laving the side of Dipper’s
neck. “I’m going to ravage you, fuck you until you can’t walk anymore, and
tomorrow, tomorrow when you’ll have to talk to Llama and General, you’ll be so,
so ashamed, because everywhere on your body, there’ll be proofs that you.
Belong. To. Me. And you’re going to love it aren’t you?”
 
Dipper exhales, feels a tear slide down his cheek before Bill licks it, and
finds his voice again. It cracks, small and hesitant but it’s there.
 
“Yes master.”
 
He feels more than he hears Bill’s breath catch. Then his back leaves the wall,
and he’s thrown on the bed. Bill watches him like a predator watches its prey.
His eyes are completely red by now, and glow so strongly in the dark that they
illuminate his face. Dipper can’t help but stare, the blood on the side of a
dark lip, the eyeliner a bit smudged on the corner of the eyes, the brown skin
disappearing behind the bowtie and the white shirt.
 
“I like when you call me that, my sweet queen.” He pecks Dipper’s lips, a
cheeky smile stretching his pretty mouth. Dipper’s eyes widen and he flushes at
the pet name. Bill has never called him that before - it’s, it’s weird. And it
feels good somehow. “You like that name?”
 
He shakes his head, trying to avoid the knowing stare. A hand grazes his
clothed cock and he whimpers, shakes his head again. Bill’s chuckles is now the
sound he hates the most he decides (he loves it, loves when the hot breath
brush his skin).
 
“Don’t lie pet.” The hand is now a fist and it hurts, so much, but it’s good as
the same time and his back arches in the touch, a keen escaping his lips. “Or
you’ll be punished.” Bill’s voice is still pleasant as ever, a bit breathless
perhaps, but there’s a warning he can hear, loud and clear. “But maybe you want
that, my queen?” The fist tightens again, then moves, slowly. “Maybe you want
me to spank you, like a naughty child? To give you a cockring and to come
inside you while you cry desperately for release?”
 
Dipper can’t keep his eyes open now, filled by the mix of pain and pleasure he
discovers under the touch of his god. He shakes his head, mouth open, saliva
dripping and small moans escaping him now and then as Bill continues to
pleasure him over his pants. Then...
Then he simply stops.
 
“What - Bill -”
“Oh, pet, and you were doing so well.” Bill’s smile is wide, full of sharp
teeth still red from Dipper’s blood. He tuts, giving Dipper a slow wink as he
tugs at Dipper’s pants. “Now come on, give me a show kid or I’ll really punish
you.”
 
Dippers bites his lips, tastes blood, faintly. Then he gets on his knees on the
bed. His shirt is still on his shoulders, opened and wet with blood so he
starts by that. He imagines a song - anything slow enough to makes Bill wants
him, but catchy too, so he’s not boring - and swings his hips. Once, twice. He
sighs, closes his eyes to avoid the hungry stare.
 
His shirt falls from his shoulder, kept on him only by his bent arms. He makes
a show out of it, brushes his chest slowly. He’s not a fan of toying with his
nipples but grazes them anyway, feels a spike of something when the shirt
finally falls on the bed. He opens his eyes and - oh. Bill is stroking himself,
slowly, excruciatingly slow, his eyes looking like they’re devouring Dipper. He
shivers, shifts and feels his erection against his pants. It’s painful but - he
doesn’t care because this is for his master, an order he has to follow,
happily. He smiles, small and nervous and undoes the button of his dark pants,
can’t take his eyes off of his god’s hand, going up and down on the dark cock.
 
“Come on pet.” Bill breathes, a smirk on his face. “You want me to take you, so
get on with it.”
 
Dipper laughs, feels like teasing a little and plays with the button before
sliding everything off, pants and briefs. He’s naked and on his knees and feels
so exposed (oh god, god, what’s he doing, he’s in bed with Bill Cipher, a
demon,hisdemon, he’s going to hell). Bill lets out a breath - a moan - and
crooks a finger at him, mouths come here.
 
Dipper crawls, because he’s not sure he can stand and Bill moans again at the
sight. Dipper feels his cock hang between his legs, a reminder of his desire
and, as he reaches Bill’s legs, nuzzles the knees of his god. A hand grasps his
hair, tightly - he can’t help whining at the pain, mouth hanging open against
the jeans.
 
“You look so good like this, on your knees at my feet.” Bill muses, petting
Dipper’s hair. It feels good, if a little too rough. “I should keep you like
this. Naked, with a collar and a leash. How would you followers feel, seeing
you like this, I wonder.”
 
Dipper’s eyes snap open and he tries to get away, because no - no way. He’s not
doing that, he can’t,he can’t, but Bill’s fist is like iron and the more he
tries, the more it hurt, not the good kind, the kind that makes him want to cry
out and hide. Bill shushes him, but the panic is too strong and he begs:
 
“Master - master please no. They - they believe in me, please.”
 
Bill smiles down at him, probably pleased by the pleading, then frowns as
Dipper doesn’t calm down. He probably angered him, oh god, he can’t deal with
this, not now. They were supposed to have a good time and he ruinedit.
 
“Pine Tree that’s enough.”
 
The hand releases him and he staggers back, tears falling down his face.
Apologies stumble out of his mouth like broken pleas. Bill - oh god, he can’t
look at Bill, with his disappointed frown, like when Dipper failed.
 
So he runs.
 
He runs and tries to open the door (nevermind that he’s naked, and where would
he go anyway this is his room) but it won’t bulge. He curses, because of course
it won’t, Bill spelled him locked so they wouldn’t be interrupted.
 
“Dipper.”
 
He freezes on the spot at the sound of his name - his actual name. The name
he’s given himself, the one he gave to Bill and everyone. The one that holds
power over him.
Something grazes him, slimy and cold and he jumps (what?). He tries to turn
around, but something (on the corner of his eyes, he catches something red and
white, like muscle out in the open) presses him against the door. He tries to
say something, anything (sorry, I’m so sorry) before another thing goes inside
his mouth, gagging him.
 
Bill what are you doing?!
 
“Oh my dearest queen.” He can’t see - his eyes are covered now, and he shivers,
feels cold. “If you’re wondering, they’re mine. My tentacles. Oh, how they love
you. I’m sure they’ll enjoy fucking you against this very door too.”
 
What?
 
He tries to speak through the - the tentacle - but nothing comes through except
a muffled moan. Then he tries to move, to get away from the door despite not
seeing anything but as soon as he steps back there’s Bill’s warm body waiting
for him and he’s slammed back against the wood. Tentacles wraps around his
limbs, turns him around, like the strings of a puppet.
He struggles, moans again pitifully, and shakes his arms but to no avail. Bill
sighs and Dipper feels a kiss just below his lips, strangely sweet for the
demon.
 
“Do you trust me Dipper?”
 
He stops moving.
 
“I know your limits. You talked about your family - how you don’t want me
bringing them into this. But you also said you might enjoy humiliation. We’re
talking about simple talk here.” A hand caress his chin, thumb pressing against
his open mouth. “Dirty talk. It turns you on.” The other presses against his
cock and oh. Oh. He got softer in his panic but now, now that Bill’s voice
resonates against his ear, warm and reassuring he thinks that yeah, yeah he can
go with that. He can trust his master. “Never worry Dipper. I know your
limits.” He repeats again, voice firmer this time. “I’m not going to do
something you don’t like. I take care of what’s mine. And you?”
 
Dipper wants to kiss him so badly. He can feel the grin against his throat, as
Bill mouths his skin, probably looking for a new spot to bite.
 
“You, you’re very much mine.”
 
Bill does bite him, but softly, only to remind him he’s here. Dipper whines,
disappointed. He wants to start over, to continue, god he doesn’t know, but if
he could, oh he would beg. The warmth of Bill’s body disappears and he turns
his head. He’s scared, just a little, because he can’t see or know what Bill’s
up to. The tentacles move a bit, spread his legs. He blushes, feels so utterly
exposed he wonders if using his magic to disappear would be the better choice.
 
“Now, what to do with you my pet.” Bill’s voice sounds far away, but not too
much. Dipper wonders if he’s back on the bed, stroking himself again as he
watches Dipper being helpless. It excites him somehow. He almost wants to laugh
(dear god I’m fucked up aren’t I?). “I could suck you off, make you come in my
mouth and then make you taste yourself…”
 
Dipper swallows a lump in his throat, feeling both impatient and afraid.
 
“Or I could let my tentacles fuck you, until you’re so tired you can’t stand.
Then I’ll eat you out - make you writhe and moan against my mouth because you
can’t take it anymore. But I can do as I please, hm? I’m your master after
all.”
 
He nods, desperate.
 
“Alright then. Let’s have fun.”
 
The first tentacle easing into him is small, smaller than the ones binding him.
It oozes something (Slime maybe?) and it feels… Weird, to have it inside him,
feel it pulse, spitting liquid inside his hole to lube him. He tries to shift,
to move away from the tip thrusting shallowly inside him, but the other
tentacles won’t bulge, and all he manages to do is make the limb grow bigger,
wider.
 
He would have gasped, if not for the gag still in his mouth. He can feel saliva
running down his mouth, hears the little keen sounds he makes and the low
groans that Bill makes, from across the room. He feels full already, and
wonders - how large can the limb grow, how far can it go inside of him. It
thrusts once, then twice and he moans around the tentacle inside his mouth,
feels slime (or maybe it’s his spit). It’s weirdly arousing, to feel the sugary
stuff run down his throat.
 
And then, he’s moving, the tentacles throwing him on the bed, back into Bill’s
arms. His gag is lifted, leaves him coughing a little as Bill ravages his mouth
again. He feels Bill’s erection against his back, and even without seeing
anything, he knows Bill’s grinning, as Dipper’s legs are held wide open, ready
for the tentacles’ taking.
 
“My perfect little queen.” Bill whispers, blowing hot air inside Dipper’s ear,
licking and biting the shell. Dipper cries out as something else enters him
with the tentacle still inside. It stretches his hole so, so much and it feels
so damn good. It shouldn’t because he can’t have been prepared enough but the
taste of the slime is still inside his mouth and he burns.
 
“Please, oh please, master, please…” He sobs, arching his back to get Bill to
touch him more, the feeling of the fingers caressing and nails scratching so
fucking good he can’t help but letting tears slide down again.
 
Bill licks them with a pleased sound, his hand finally, finally, touching
Dipper’s neglected cock and oh god, my god, please,tugs once, then twice. The
two tentacles are thrusting, slowly, painfully slowly, as if Bill knew how to
make Dipper begs for more - of course he knows, he’s inside your head, he’s
your god and master and knows everything and somehow, that makes it even
better.
 
“Now my sweet little Pine Tree, you’re going to come for me, aren’t you?”
 
The tentacles finally speed up, and oh, maybe it wasn’t such a good idea after
all, because now he can feel one repeatedly massaging his prostate - stopping
every now and then to avoid overstimulation, only to come back - while the
other focus on the movement, warm and slick inside of him, still growing and
stretching and ooooh god.
 
Bill’s hand doesn’t move through it all, still on Dipper’s cock, the skin hot,
the nails threatening to tear off part of his skin. Dipper’s not sure if he
wants him to do it or not, moans a bit and wiggles his hips. But Bill laughs
and tighten his grip, still unmoving. Dipper can feel
 
“I gave you an order didn’t I Pine Tree?”
 
“I - ah - I’m oh god sorry -” He’s cut off by an angry kiss, his surprised
sound muffled by Bill’s tongue and - is it forked? It wasn’t before and now,
now it’s invading his mouth, going too far and making Dipper almost gag, but
the pleasure of feeling that wet muscle is - it’s way too hot for a human.
 
Bills cuts off the kiss and murmurs something in a language Dipper can’t
understand but the feeling of it - the deep rumble, a low purr of rattled
sounds and high whistles - coupled with the tentacles pushing deep, oh so deep
and yes - yes he’s coming hard, and the tentacle on his eyes disappears just in
time for him to see Bill’s hand covered in Dipper’s semen.
 
The same hand leaves his cock and comes close to his lips, smearing them just a
bit, as Dipper pants, feels empty and satisfied. Still, he lets his mouth falls
open and his tongue goes out to lick the drying come. It’s almost sweet tasting
and he savours it, eyes falling closed. He feels tired, now that the tension is
wearing off. But Bill’s tentacles tighten their grip on his ankles and arms and
move him again, this time so he’s sitting against the wall at the head of the
bed. Dipper groans at the movement, opens his eyes again to see Bill’s cock
hanging near him.
 
“Now, now, my sweet, I’m not done with you.” Bill’s grin is so wide it looks
inhuman, fangs deforming the flesh of his cheeks, dark skin beginning to have
scales, while his ribcage is beginning to show. “Ah, yes, I did tell you
earlier that this would happen. My true form is showing.”
 
Dipper feels boneless, exhausted by the mental and physical activities. The
aftermath of the battle is finally taking its due, leaving him with a slacked
mouth and an uneven breath. So he lets Bill fucks his mouth, licks the skin and
scratches it just how Bill likes it. He lays back against the cold wall, feels
white and red tentacles caress his skin, the pain of the bitings on his throat
and the bitter and ashy taste of Bill’s cock.
 
“Aaah, you’re doing so good, Pine Tree, just taking it after a good fucking. I
should do that to you more often - but I think I would miss being inside of
you.”
 
Slime is oozing out of his hole - it feels dirty, and good, just like the low
tone of Bill’s voice as he grunts and mutters more about what he’ll do to
Dipper, to his pet and witch. Dipper smiles and hollows his cheeks, sucking
hard. Bill curses (?) in that same language from before and comes, a dark
glistening liquid shooting inside of Dipper’s throat. He can’t swallow it all,
but Bill’s already there, licking it from Dipper’s chin and kissing him, almost
tenderly this time.
 
“Come now, pet, let’s clean you up.”

But Dipper’s already asleep.
