Summary
     Bill wants to find out how resilient to being sliced open his new
     body is. Dipper is very much not about this idea.
Notes
See the end of the work for notes
“This body is so resilient! How much blood do you think it can lose before it
quits on me?” Bill looked up at the ghost of Dipper, the spitting image of the
poor kid, considering he’d taken his body just a few hours ago. His grin
widened almost inhumanly as he pulled a knife out of his pocket, no doubt
pilfered from the kitchen while Dipper wasn’t looking. “What if I just cut it
open? Think it’d last very long?”
Dipper’s eyes grew wide as he watched the demon press the blade of the knife
against his wrist, his wrist! It didn’t take more than a second for him to
shake his head vigorously and attempt to grab his own body’s hands to stop them
before Bill did something stupid that wound up with his body too dead to be
habitable any more. Of course he phased through the demon, there was nothing he
could do other than float helplessly in front of him. He’d never felt more
useless in all his life and now he was going to die because of it. In one last
attempt at appealing to Bill, Dipper let himself drift down closer to him,
crossing his arms and subconsciously chewing on his bottom lip. “If you do that
then I’m literally going to die. If my body dies then you won’t be able to run
around in it anymore, right? That’s how that works, isn’t it?”
There was a small flash in Bill’s eyes, accentuating the way that they widened
just barely at the thought. He did like having a human body to screw around in.
The knife was slowly tilted to the side, the flat edge pressing against
Dipper’s wrist as the demon inhabiting his body contemplated his options.
Finally he brought his gaze back up to Dipper, grin still stretched wide across
his face as he suddenly pointed at the kid’s ghost with the tip of the blade.
“One cut. None of those major blood pumping things of yours though, promise.
I’ve just got to find out what it’s like, I’m so past the bruising and bone
breaking phase, I’m a demon, kid, let me see a little blood!”
Dipper stiffened when the knife was aimed at him, despite the fact that he
couldn’t actually be injured in this state, and by the time he’d found it in
him to relax, he was made to tense up all over again at Bill’s suggestion. Of
course he didn’t want any cuts on his body, but it seemed Bill was intent on
doing it whether he consented or not, might as well have it be on his terms if
the demon was really going through with it. Dipper narrowed his eyes before
sighing in defeat and crossing his arms once more. “One. Only one. And it can’t
be somewhere that people will see!” He really did not feel like answering any
questions regarding self-made scars on his wrists.
That seemed like a good enough deal for Bill, considering he lowered the knife
and started making a move to strip off his shirt. “You got it, Pine Tree,
stomach it is then!” He managed to get the shirt lifted up partway before
Dipper stopped him once more.
“Are you kidding me, man? It’s Summer, what if I go swimming or get too hot and
feel like taking my shirt off? Find somewhere else.” He couldn’t very well
impress Wendy if he couldn’t even take his shirt off at the pool, he’d probably
look ridiculous!
Bill groaned and rolled his eyes, getting fed up with all of these stupid
rules, honestly there was nothing stopping him from just plunging the blade
right into his chest and letting the whiny kid’s body die, but he was nicer
than that. Sometimes. “Fine,” he replied with an air of finality, before
setting the knife aside and standing up to unceremoniously drop his shorts to
the floor, much to Dipper’s dismay. He was met with the demon’s wide grin as he
sat back down, kicking the shorts off his feet and leaving the kid’s lower half
clad only in a pair of white briefs.
Dipper chewed his bottom lip as he did his best to direct his gaze elsewhere,
not expecting the silence that followed as Bill moved to press the knife
against his skin, only to pull it away once more. When nobody had said anything
for a few seconds, Dipper dared a look back at him, only to be greeted by a
sudden cackling laughter. He tried to keep his posture strong, but his
shoulders sunk as his eyes drifted down to his own body’s thighs, staring at
the lines of scars that ran along his otherwise smooth skin, some a little
fresher than others. “Th-those are,” he started, but his voice cracked, making
his cheeks heat up before he cleared his throat and tried to continue, “I fell,
uh… into some blackberry bushes. They only scratched up right there though,
pretty funny, right?”
The look Bill gave him could only be described as knowing. He knew Dipper was
full of shit and Dipper knew that he knew. The silence that followed was tense,
with Bill’s eyes staring at him from his own body, his mouth twisted into an
amused grin. “You can’t keep secrets from me, Pine Tree, when are you going to
learn?”
And at that moment, Dipper’s head was suddenly filled with flashbacks, memories
all playing at once in a distorted mess until they came to a stop on one in
particular. He didn’t want to see this. There was nothing he could do as he
watched himself, clear as day, pressing a small blade to his skin. He saw
himself just moments before, swiping the razor from where his dad kept them,
trying so hard to keep his voice down as he turned on the shower to drown out
any sounds, to wash away the evidence. He couldn’t look away no matter how hard
he tried, it was a memory, shoved into his brain like it belonged there. Dipper
heard his voice crack, watched small lines of red mar his skin, and he thought
about the kids in school who had seen his birthmark, who locked him in the
bathroom and barricaded the door, how no one found him until the day was over
and all the buses had left. It wasn’t Mabel’s fault that she was home sick that
day, or else she surely would have noticed his absence and come to his aid.
Apparently ghosts could cry, because Dipper was tearing up pretty badly, though
he quickly pulled down his cap to hide his face as much as he could. “So what?
It’s not that big of a deal. I don’t need to look at this, just do it already
and give me my body back!” He wiped his tears away quickly and glared up at the
demon inhabiting his body, only to see that he was stifling laughter. Bill
threw his head back as he finally let it go, one hand clutching his stomach as
he flopped back on the bed and drove the knife into the mattress.
“You’re such a riot, kid, I can’t even handle you sometimes! Let’s save that
memory for later, shall we?” He wiped a tear from his eye and gave a few
mismatched blinks in Dipper’s direction. “Crying over something that didn’t
even damage your body? Humans are so pathetic, how do you even get by without
dying if that’s all it takes to get you all worked up?”
Bill’s tone of voice was grating, to say the least, he had a way of yelling
everything and sounding far too enthusiastic about things that were not the
least bit appropriate. Dipper clenched his fists and flew at him, which of
course did him no good whatsoever. He couldn’t hurt Bill like this, he couldn’t
do anything. Those feelings of complete and utter uselessness came back just as
hard as they had on that day and it took everything in his power not to just
start screaming as Bill continued to laugh like Dipper being upset was the most
hilarious thing in the world.
Before he even had a chance to register what was happening, Bill had torn the
blade from the mattress and pressed it into his thigh, right over the top of
his scars. So much for hoping that those would heal and go away forever, he’d
never pressed this deep before. The demon’s gaze locked on Dipper’s for just a
brief moment before he was focused on his hand, slicing a long line all the way
across his thigh. That was it though, they’d made a deal, but Bill wasn’t
stopping. With a pleased sigh, Bill pressed his legs together firmly, so he
could continue his line over to the other thigh, before dragging the knife in a
diagonal line toward his crotch, then completing it by marking a similar cut
down the first thigh, where his final line met with the original one. Dipper
shouldn’t have been surprised at the shape. With his legs pressed together like
that, the cuts formed a clear triangle.
“You said one cut,” he muttered after a moment, arms crossed and head hung low.
“It was one cut! I didn’t pick the knife up once!” Bill held said knife up to
inspect the blood that dripped down the blade, licking his lips as his chest
heaved from the deep breaths he was taking. “Felt amazing though, I can’t
imagine how you could want to lock yourself away and cry while doing this. You
like the design, by the way? Thought your original pattern was a little dull,
so I spiced it up for ya!”
“That’s my body!! I have to look at… at that every day?!” Dipper was fuming,
the aura of his ghost actually glowing a light red color. “I hate you, I don’t
think I’ve actually ever hated someone more in my entire life!”
Bill’s eyes narrowed, brows furrowing, though the grin didn’t leave his lips as
he brought the knife up close as though he wanted to smell the blood on it.
“What a charmer, it’s nice to see that you seem to know how to talk dirty to a
demon.” There was something in his voice that made Dipper shudder, the red
vanishing from his aura as he felt disgust take over the anger. And then Bill
stuck his—Dipper’s—tongue out to lick the blood from the blade with blatant
disregard to the sharp edge that bit into the muscle. “Say it again.” His voice
was deeper than normal, and actually sort of quiet for a change, it made Dipper
want to gag.
“You’re disgusting!” he spat, letting himself hover down closer to the floor
with a scowl.
“Ohh man, that’s it, stellar job, kid.” Bill let his bleeding tongue run across
his teeth, staining them red as he dropped the knife on the bed next to him and
let himself lay back with something that almost sounded like a moan. “This is
fantastic, never thought a human body could feel so good!” His hand drifted
down, grazing against the crotch of Dipper’s underwear, which was (much to
Dipper’s horror) sporting a visible bulge, and finally the hand came to rest on
his thigh, just shy of one of the cuts. “Looks like pain isn’t just hilarious,”
he managed under a laugh, fingers dancing along the laceration, nails pressing
into it. He hissed, though there was a pleased look on his face as he drew even
more blood from the wound. Dipper was going to get a fucking infection at this
rate.
There was nothing that Dipper could do about this, Bill was the one with a body
and he was, well… useless like this. He could only watch on in horror as the
demon brought his bloodied hand up and shoved his underwear down before taking
hold of his erection and stroking. Bill started making all these obscene sounds
almost immediately, moaning and bucking his hips as he used his blood like
lube. It wasn’t until Dipper finally tore his gaze away from the mess that he
realized Bill was staring at him, lips pulled into a tight grin, eyes almost
unnaturally wide. This was all so wrong, he wanted to scream and shout and
throw himself at the demon in front of him, but he was certain that anything he
did at this point would only encourage him, so he turned away, glaring at the
wall and trying to plug his ears to keep all of those moans from reaching them.
And then all at once, Bill was throwing his head back, a loud and exaggerated
cry leaving him as he bit down hard on his cut tongue and came all over his
shirt. It had to be over then, what else was there for Bill to do now? Dipper
dared a glance back at his body, to find it a horrible mess, blood smeared all
over his legs and sheets, a spatter of white and red that spread across his
torso and seeped into his favorite shirt, and Bill’s awful stupid laugh
starting to echo through the room.
“You got a short fuse, Pine Tree, I was hoping to mess around a little longer.
That was fun though! I’m sure I’ll be seeing you around real soon. Have fun
explaining this one, you’ve got about thirty seconds by the way. See ya!” And
then Bill was gone, leaving Dipper’s body limp and wrecked. He didn’t know what
the heck he meant by that ‘thirty seconds’ line, but he certainly wasn’t about
to take the chance on it being some sort of time limit on how long he had to
get in his body.
With a groan at the pain to come, he flew down, taking control back. For a
moment, he felt nothing, and he opted to take deep breaths as he struggled to
pull his underwear back up. His hand brushed one of the cuts in the process and
suddenly his body was screaming out in agony, everything hitting him in a rush
of stinging pain. Tears rolled down his cheeks and he rolled onto his side,
pushing the knife to the end of the bed and managing to smear more blood on his
sheets along with it.
That was when the door opened. His seconds were up and he looked like the
poster child for a self-harming ad. He shut his eyes before he could see who
had seen him, and prepared for the biggest most unbelievable explanation of his
life.
