All was silent and still. Fields of darkness stretched out in an endless expanse; existence was an illusion, time was indefinite.

...

A shrill cry of horrible agony tore through the dead air, followed by a deafening static crack and waves upon waves of pure torture.

Dipper's eyes popped open. The first thing he noticed was that everything was grey. No surprise. Above him, a colourless Bill hovered with indifference plastered obviously across his face; he blinked once. Wait a second...colourless Bill? Even in the dreamscape, Bill usually retained his bright yellow pallor. The pair stared silently at each other as seconds ticked by, and nothing could have felt any more awkward than this.

Finally, when he could bear it no longer, Dipper made a move to sit up.

"Augh, what happe-" his sentence was cut short by another charge of electrifying pain that caused his body to convulse and writhe against the hard wooden floor. It was as if a torrent of hellfire blazed through his veins from the inside-out, wracking him limb from limb.

When it was finally over after those few ungodly seconds, the boy panted furiously and clutched a hand over his heart-halfway out of reflex, and halfway to make sure it was still beating.

"What the heck was that?!" he snapped, glaring up at Bill.

"Oh good, you're awake. I just thought a couple thousand volts of pure electricity might help you come to, no need to thank me."

"I was awake before you nearly killed me, thanks," he groaned as he sat up. "It's not like you were staring right at me or anything."

"Pfft, semantics," Bill shrugged. He rolled his eye. Dipper shook his head and ran a hand through his now-frizzy hair, rubbing it back down to how it should have been.

"How long was I out?" he asked.

"Hm, 'bout a year."

"What?! Oh my god, no way. What am I gonna do? A year, seriously?"

"Shooting Star found herself a boyfriend, Stan Pines is dead, Red moved to Portland, and Gideon declared himself the new dictator of Gravity Falls; things are pretty great!"

"Ugh, cut the act, Bill, I know it's not true."

"You're right, Shooting Star actually keeping a boyfriend is hilarious!" Dipper rubbed his eyes at this and grimaced (but he did have a point).

"Alright, Bill, time to pay up. You have my soul," which, now that he mentioned it, Dipper noticed that the jar containing his soul was draped around Bill's being and dangling just below his bow tie, "now it's your turn to...pay me back."

"To fuck you, you mean!" the other responded in his usual cheery tone, which made it only a hundred times more uncomfortable. Dipper actually cringed at the remark as he stood up and dusted himself off. He stumbled a bit, unused to his body feeling so empty and light. His legs felt like wet noodles under a weightless torso.

"Whatever. Let's just get on with it."

"Let's get it on, you mea-"

"Just come on!" Dipper growled, balling his fists and marching angrily past Bill towards his bed.

"Yeesh, kid, at least let me work you over first!" Bill laughed, following behind him. Dipper decided not to dignify that with a response. Stupid triangle.

A tiny part of himself deep down wished he could take it back, play it off as a joke, but it was way too late to turn back now. Still, he knew he had to do this even if he could go back, it just sickened him is all. Hopefully, this would be over quick.

When he reached the bedside, he spun around to face Bill and glared harshly at him through hollow eyes, wide and devoid of life. He crossed his arms at his chest and huffed.

"Yikes, what's with the attitude, Pine Tree? Isn't this what you wanted?" Bill squinted.

Dipper didn't respond, he just heaved out a sigh and relaxed his shoulders. Sitting back on the edge of the bed, the preteen began to disrobe-shrugging off his vest first, then removing his hat. His shirt came next, and promptly after he kicked off his shoes and was tugging at his socks when Bill approached him.

"Seems to me like you think this is a chore, are you having second thoughts about our little deal?" he pondered, twirling his finger in the silvery string of the ornament.

"No, I'm not. I...I want this," Dipper struggled to say. The words tasted awful in his mouth, like sour dirt and gym socks. He took a deep breath and pulled on the waistband of his shorts. He shakily pulled them down and strained, "I'm just nervous. It's my first time."

The moment those words left his mouth, he instantly regretted them. Bill broke out into a humiliating laughter so thunderous, the room shook.

"Pine Tree, you just get more and more pathetic, don't you?"

"Give me a break, I'm twelve!"

"Ha, no, it's not that. It's just funny that you're going through all this to get laid by a demon. You're really somethin', aren't you?" Dipper chewed on his tongue until he thought he might bite clear through it. He wanted to make a remark, to give the jerk what-for, but there wasn't anything he could say without saying too much. Instead he just rolled his lifeless eyes and shook his shorts off from around his ankles. "Also, 'I heart BABBA' boxers, kid? Really?" Dipper slapped a hand over his forehead. Why didn't he remember to change before getting into this? "What, do they say 'Disco Girl' on the back, too?"

Yes.

"Can we please just stay focused?" Dipper groaned, cheeks dusting over with blush. He sat back into the mattress and fixed his attention on Bill. The demon hovered just in front of him with an amused crinkle to his eye. "And stop staring at me like that!"

"What? But you said to stay focused and that's what I'm doing," Bill chuckled, placing a palm against Dipper's clothed crotch. Dipper jumped slightly and grit his teeth. That felt wrong on so many levels. "Or did you mean for me to focus on other areas of you instead?" A chill ran over him as Bill's warm hand began to move in slow motions, causing him to let out a stifled breath. His body began to feel numb and slightly tingly as the blood rushed towards his abdomen. "Do you like that, Pine Tree?" He was not going to answer that question, but his body wasted no time in an eager response. Under Bill's hand he was growing, and it was giving him an uncomfortable nausea to even think about it.

Bill removed his hand to hook his thumbs under the other's boxers and edge them down his waist until his semi was free. An unpleasant shiver passed over the preteen's body. He stared down at himself with shame, pondering his own body's reactions to Bill's touch.

"C-Can you do more?" he asked somewhat breathily. It was shameful, but necessary.

"You humans are so needy," Bill said with snark, rolling his eye. He took hold of Dipper's half-hard on and gave it a experimental squeeze...maybe a little harder than he should have.

"Ow!" Dipper jumped, clenching the muscles in his stomach at the pain. "Not like that!"

"Well, pardon me, Pine Tree, but I don't go around giving handjobs to preteen boys recreationally, if you can believe that." Ugh, it was like every word that came out of him was making Dipper's stomach twist that much more. Did he really have to be so point blank?

"I've never done this before either, alright, so don't act like you're the victim."

"Ha ha! No, you're definitely the victim. All your life!" Bill doubled back in laughter, releasing Dipper's cock. Dipper clapped a hand over his face and shook his head, groaning. What was even the point? Maybe he was wrong and this wasn't worth the humiliation. But then, Bill stopped and straightened up with yet another look that spelled trouble. "Say, Pines, how'd you like to learn a bit of Latin?"

"I-what?"

"Yeah! It'll be great," Bill chuckled, grabbing Dipper's length again. "Every time you say a word correctly, I'll reward you." He gave the other an enticing stroke to offer an example.

"What? Wait a minute, you're supposed to be doing this in return for my soul; I shouldn't have to work for it!"

"Oh, c'mon, just think of it like a little extra. You're learning Latin and still getting what you want. Frankly, you should be thanking me for being this generous."

"You know what, I'm not even surprised right now. I literally should have seen this coming." Bill gave a small snicker and stroked him once more at that last part. "Alright, I'll play along. Whatever gets this moving faster."

"You make it too easy for me to make fun of your words, kid, it's losing its charm." Dipper rolled his eyes. Maybe if he got bored, he'd shut up.

Out of thin air, Bill fabricated a booklet and moved it towards Dipper. The preteen grabbed it from the air, propped himself up on his elbows, and flipped through the pages to see every page was filled from top to bottom entirely in Latin. It didn't much look like a vocabulary book or even an information guide of sorts. In fact, it read like sort of like a story. He flipped back to page one and took a breath.

The first sentence must have flowed perfectly because Bill gave him a few successive strokes. A few of his leg muscles tensed at the feeling, but he continued without much hesitation. The next sentence was difficult to pronounce and it resulted in Bill giving Dipper another unpleasant squeeze.

"Ow!"

"Try again, Dipstick."

"This is stupid!" Dipper said shaking his head.

"Hey, if you wanna go back on our deal..." Dipper frowned.

"No," he grunted. Bill gestured for him to continue.

Growling under his breath, Dipper repeated the sentence a few times, getting both strokes and squeezes from Bill, until he was getting nothing but smooth motions against his cock. A short gasp pushed through his teeth and he kept going.

Word by word, he read on, turning pages until his mouth got dry. Taking a brief moment to wet his lips, Dipper glanced up from the book to see Bill with his eye shut, radiating a light aura different from how he would have said was the norm. He couldn't quite tell for sure because everything-even Bill-was hued in various shades of grey, but he would say Bill was a bit darker, maybe perhaps what would have been a redish colour? Or perhaps pinkish? And said light wave was glowing in pulses. Dipper cocked his head a bit and squinted at the sight, then looked down to his cock to see Bill still stroking it absentmindedly, but still he was still only half hard. This was a disaster, there was no way he was going to get far enough if this kept on like it was.

"Don't stop, Pine Tree," Bill rasped, opening his eye half-mast. Gears in Dipper's head turned and rutted against each other until finally it clicked. Oh god.

The booklet went flying across the room as Dipper flung it as far away from him as he could. That was utterly disgusting! Goosebumps rose on his flesh, blood running cold. Oh god, oh god, oh god.

"No! No way. No, no, no, no, no, no, and no. I am not doing that," he floundered, scrambling to cover himself up. A hand caught his wrist. Bill looked angry, if the glint in his eye was any indication.

"Here's the thing about that: you leave me halfway and I'll leave you halfway and keep your soul." The book levitated via magical influence back over to Dipper where it floated patiently beside his head. Something told Dipper that he was going to leave this situation halfway no matter what he did, but something else told him that Bill was going to be a lot more unhappy than that if he left Bill halfway; and while he wasn't very phased by that threat, Bill taking his soul and just leaving would be crushing the rest of his plan and that was unacceptable. So reluctantly, Dipper snatched the book out of the air, keeping a glare on Bill all the while, and sighed, continuing from where he'd left off.

Pages later, Bill was audibly moaning at each risqué syllable trickling from the boy's lips. And after lots of rewarded jerks to his stubborn and shy cock, Dipper was finally hard. He'd even grown used to the, now disturbingly satisfying, pain of Bill's squeezes; which, if he was honest, is probably what was finally enough to get him up. He hid behind the booklet, gripping the paper so hard it crumpled beneath his anxious hands. His face burning, he realized he was very, very wrong before-things definitely got incredibly more awkward.

Whatever he said next was enough to make Bill give a long, drawn out moan and tighten his grip on Dipper's cock. The preteen arched his back and bucked into the clutch as a short, breathy gasp was pulled from between his teeth. He instantly clapped a hand over his mouth with wide, mortified eyes. Did that sound just come from himself?

"Kid, I gotta admit...you have a way with words," Bill breathed, staring down at the motions he continued to make around Dipper. "Your tongue is very talented." A rush of heat, manifested in a violent shiver, raced to Dipper's groin. His cock twitched in Bill's hand, causing the other to give an satisfied glance at him. The aroused sigh that left him was just plain sinful. "So listen, I hate to say it, but...I can't say I know much about human reproduction. It's gross." Dipper pursed his lips. Seemed to him like Bill was rather enjoying himself. "Human sex ends with male ejaculation, right?" Wow, that made him cringe. His entire body tensed up and shuddered.

"I-yeah. Usually, I think," he replied, "That's what Mabel said Grunkle Stan told her." Bill didn't respond to him, lost in his own (probably demented) world. A few silent moments pass before he spoke up again.

"Keep reading," he said. Dipper studied his face before nodding and looking back down at the pages.

He'd picked up a pattern with the way letters were pronounced, so most words came across far more smoothly than they were when they started. He was also fairly sure he knew which words did the most to Bill, so he made sure to say those with a little extra gusto when they came about. When he did, Bill usually involuntarily gripped harder, which is exactly why Dipper did it. Still, the words 'this is so wrong' repeated in Dipper's head like a broken record, the further he went.

Finally, Bill stopped him. Dipper looked up from the pages, half-confused, half-dazed. Every bit of his face was flushed over, the rise and fall of his chest erratic.

"Ahh, that's the stuff," Bill exhaled. Dipper averted his eyes. "Now, this is important, so listen up: I need you to say my name and then 'expletio', you dig?"

"Why?" the preteen questioned, flipping pages in the booklet. "It doesn't say anyt-"

"Just-just do it, kid!" Bill insisted.

Against his better judgment, Dipper obliged.

"Bill Cipher..." he began hesitantly. Bill looked up at him through his lashes, eye filled to brim with lust. "expletio!"

Light grey flames exploded from Bill's body, encompassing both himself and Dipper below. Surprisingly, they didn't burn at all, just like when he shook on deals. His grip on Dipper's cock was released as he was cast into the throes of his orgasm, shaking and emitting a brilliant light that nearly blinded Dipper. The preteen below shielded his eyes with his forearm. Something similar to a shrill pterodactyl screech flooded the room, causing a ringing in his ears.

And then it got quiet.

The sound of a thud hitting the floor made Dipper uncover his eyes. Bill had fallen back and landed flat on the floor, arms and legs spread like a starfish. He seemed spent. Dipper raised an eyebrow at him.

"Whew, that was fun," he said in a steady voice. "Tell ya what, kid, I got some place I need to be here in a sec'. I'll catch a raincheck on that male ejaculation of yours." Ugh. "So pretty much, you'll be getting double what you asked for, plus that whole Latin thing," he chuckled at that, "sound fair to you?" Dipper opened his mouth to protest the idea of having to do this all over again-and the fact that Bill still left him halfway after he kept going-but before he could get any words out, Bill cut in. "Great! Well, it's been a real riot. Smell ya later, Pine Tree."

And with that, he vanished in a fireball of malevolence, leaving Dipper alone in his shared bedroom.

It was silent.

And everything was grey.
