The door of the underground lab closed with a hiss, and Ford exhaled. It had been yet another long, exhausting day. The twins had somehow managed to get them all in a life or death dating show. If they failed to charm a man eating, sentient horse it would, well, eat them. It had narrowly been defeated by a combination of Mabel’s theatrics, Dipper’s smarts and Soos’ surprising skill at wielding a massive carrot as a jousting implement.
With a sigh, Ford sat down in his armchair. Dipper. What a smart young boy he was. Truly, it was his intellect that Ford was impressed by. To be so clever and analytical, at that age? And how he looked up at him, for even the smallest technical observation. Yes, Ford couldn’t deny he was charmed by the boy. It was all innocent, he told himself. His appreciation for his intellect is why he always tried to bring Dipper onto whatever project he had going. Dipper’s look of amazement as Ford spoke of his many misadventures is why he always asked him to sit on his lap, as a way to bond. His appreciation of his youth is why he always lingered when Dipper was taking a shower, it was all—
“Oh, who am I kidding?” Ford said out loud, to no one in particular. He was fully aware of his… feelings, towards his great nephew. This was simply part of a ritual he did. Every night, when the day was done, he’d try and convince himself he was just a regular old grunkle who didn’t have any uncouth feelings for his little nephew. That he didn’t want to hold that boy down by the hips and thrust against him so hard all Dipper could do was moan and beg for more. That he didn’t want to see those big, innocent eyes get ruined with lust. That he didn’t want to see Dipper on his knees, begging—
God. What kind of disgusting person was he? But so long as he didn’t act on it, it was fine, right? Everyone has thoughts, good or bad, the important thing is one's actions. So long as he didn’t hurt Dipper, he wasn’t doing anything wrong.
That is what his therapist told him, a week before he dissappeared. When he got back, he couldn’t find a trace of her. He had been gone for 30 years, so perhaps that wasn’t that odd. He shook off the thought, and opened his drawer.
Moving aside the assortment of research notes, pens, and dice he kept in the drawer, Ford turned a dial. The dial revealed a secret compartment on the side of his desk. After inputting the code, he finally got to his prize. His most precious possession, the thing he took the most care in keeping secret of. Even more secret than the trans-dimensional rift. That, Dipper knew of. No one knew of these, not even Dipper. Especially not Dipper. They were, after all, pictures of him.
He started taking them pretty soon after he got back, when his desires once again led him to the depths of immorality. He told himself it was for the best. It was better to do it here, in private, where it couldn’t hurt anyone. And as long as Dipper didn’t know he took pictures of him in the bathroom, or out playing in the woods, then it was fine. He could indulge his desires safely, and Dipper didn’t have to have the image of his great uncle Ford ruined.
With a grunt, Ford unzipped his belt and let his sizable cock hang free. He looked through the stack, before landing on one of his favourites. It’s simple, innocent even, from a certain point of view. It’s a picture of Dipper undressing right before bed. Ford took it when Mabel was in the bathroom, after talking to Dipper one on one for a bit. It showed him in his boxer shorts, taking off his shirt. His thin body on display, Ford could almost see his cock bulging against his stomach.
With that thought, he finally started jerking off. Grunts and moans escaped the old man in a rhythmic, predictable pattern. He couldn’t help being meticulous and careful in everything he does, even something as lewd as this.
That is, until he started looking through the pictures. Undressing was always his start, but it’s never enough. He needed to see more. He needed to see Dipper’s useless little cock, how small it was compared to his. He needed him. He needed him. God he needed him.
It was around this time any rhythm or awareness Ford had left faded, solely and singularly obsessed with his little shota nephew.
He didn’t know when he passed out, and started dreaming. All he knew is that, instead of looking at pictures of his nephew, he was now balls deep inside of him. He didn’t know where he was. It felt like the attic of the house, where Dipper and Mabel slept. If he had bothered to look around, he might’ve realised he was wrong. He might’ve seen some floating items, or doors where there shouldn’t be any.
Instead, all he saw was the needy face of his cute, helpless little nephew, begging for him to thrust harder, harder, harder!
With one final push, Ford came. He held his dick deep in his lubed up asshole, making sure every drop of his cum went inside him before collapsing from exhaustion.
“Wow sixer, you’re good, you know that?”
Ford let out an ungodly scream, as he pushed himself up. Under him, where moments ago was his cumfilled nephew, now was Bill. Well, that wasn’t entirely accurate, it was Dipper’s body with the head replaced with a triangle, smoking a cigarette.
“Use a condom next time, will ya? I might get pregnant!”
“B-Bill!” is all Ford managed.
“The one and only!” Bill, now done with the cigarette, tossed it aside. It grew legs as it landed, and crawled away to somewhere.
Ford blinked, and now Dipper's body was entirely gone, replaced with the full triangular visage of Bill Cipher.
“Can old Pine Tree even get pregnant? Humans are confusing, too fleshy if you ask me.”
“Wh-What do you want?” Ford asked, panic in his voice. Bill wasn’t supposed to be able to come here, he shouldn’t be able to be here or see this this was supposed to be safe—
Ford’s spiralling thoughts were interrupted by Bill’s cheery laugh.
“Oh Sixer, you ARE a joker. I want the thing I always want!”
Bill put his hands together, and two mini Bills stand on it shaking hands. They speak at the same time.
“A deal!”
Bill closes his palms, and the two smaller triangles scream in pain as they are crushed and burned into nothing. Ford visibly winces.
“I’ll, I’ll never make a deal with you, demon!” He shouts. The walls shake as he does, and part of the roof collapses next to them.
The moon is inverted.
Bill laughs again.
“Be careful there, you could’ve killed us poindexter! If you had, you wouldn’t ever have known what Pine Tree’s insides feel like!” Bill laughs again as he spins upside down. “Though I hope I didn’t disappoint!”
Ford’s mind was racing. A way to have Dipper? To finally have to stop pretending he didn’t want him? If—
He shook his head, trying to stop this thought process before it got any further.
“C’mon Sixer, no need to be shy! I saw allll those dirty things you think about your little nephew.”
“I- You’re wrong! I don’t think of him like that at all!” Ford spoke with a confidence he knew he hadn’t earned.
“Sixer, Sixer, who are you kidding? We were both just here for what happened!”
“You, you manipulated me!”
“Sure I did, but I didn’t manipulate you into wanting to fuck your nephew. That’s all you, that all came-” Bill pointed at Ford’s heart, and Ford scrambled back “-from there!”
“Shut up! Shut up, go away! I will never make a deal with you again, now begone!”
This final shout finally rips away the facade in which they had been. The inverted moon shone as brightly as it could, the constellations of equations across the sky holding this fragile reality together at the seams. The grass down below was the same as that horrible place he spent all that time, with Bills form still burned in from their last encounter.
“Tough customer, geez.” Bill said, “You know, how’s this sound? I’ll give a sample, for free. We’ll talk tomorrow, see if ya changed your mind.”
Before Ford could say anything, Bill floated up.
"Remember! Reality is an illusion, the universe is a hologram, buy gold, see ya!"
Bill’s departure left the world shaking and reeling, falling apart, and soon enough-
-Dipper woke up.
He stretched out, the sun shining down on his face. God, why did he have to get this side of the room? With a groan, he turned to Mabel. Mabel, as it turns out, was already up and getting dressed.
“Sorry brospeh-” she says, after deciding which sweater to wear and throwing the other behind her into The Pile “-I’ve got a date I gotta get ready for!”
Dipper sat up slightly, scratching his head. A shiver goes through his spine. That was weird. Shrugging it off, he turned to his sister.
“Again? Another blonde douchebag?”
“He's got brown hair, actually!”
“Right. Call if he turns out to be a bunch of gnomes again?”
“You betcha! I’ll make you save my ass.”
Dipper yawned, and turned preparing to get out of bed.
“Why? Cause you can’t do it yourself?”
Mabel stuck his tongue out at her brother.
“No, because I don’t feel like doing it myself so I’m making my dorky brother do it! Now, I’ve gotta go cause we already have the day planned out!” Mabel held out her fist, which Dipper dutifully bumped. Then, she ran off.
“See ya nerd!”
“Don’t die!” Dipper shouted after her.
With that, he was alone. A relative rarity, for Dipper. He stood up, stretching again. The air hitting his exposed skin again makes him shiver. What the heck? It wasn’t even cold. Again trying to ignore it, he started to undress.
First his shirt. As it slid over his nipples, he let out a little whimper. Why was he so sensitive? Was it puberty? Or maybe something was wrong? A little worried Dipper dressed himself fully. When he put on his shorts, he nearly moaned from the friction against his… member.
He didn’t know what was going on, but it was something bad. Nervous, he went downstairs. He was terrified of what would happen if someone discovered his current state. Preparing himself for an awkward morning dinner, he yelled hello at grunkle Stan. Grunkle Stan, however, wasn't there to hear. In fact nobody was. When Dipper reached the breakfast table, there was a note from grunkle Stan.
Out hunting with Soos and Wendy. Will be back. Don’t tell the cops anything. - Stan
Dipper had enough on his mind already to care about this potential hunt, or the reasons as to why he might be left out. He had other things on his mind.
Getting himself a breakfast, he started to think of possible reasons for his sensitivity. Maybe it was just a part of puberty? But nothing he’d ever read about told him this would happen. If anything, it felt more like he was in heat than anything. Which doesn’t make any sense, that’s a thing animals did. Unless he ate something? Or touched something? Maybe the dating show did something weird to him? God what if something was wrong? He should go and ask Fo-
As soon as Dipper thought of his other great uncle, a shot of pleasure coursed through him. He desperately held onto the table. Why… Why does uncle Fo-
More pleasure, and Dipper was suddenly acutely aware of the erection now straining against his far too tight boxers. He had to deal with this, he had to, he could ask Fo– Ah!
His hand already in his pants, Dipper left his breakfast half uneaten. He moved in a haze, barely aware of his surroundings, only aware of how fucking needy he was. At some point he managed to get on his bed.
His hands were pumping his twitching, desperate cock, craving release. Any thought to origin, causes, dangers, it all dribbled out with his precum. There were only two things which Dipper's horny mind could still cling to. Cumming, which promised release from this tormenting pleasure, and Ford, who only made the pleasure worse.
Dipper wished his grunkle was here, filling up his virgin asshole. Without thinking, he started fingering himself. The pleasure only increased, but that’s all it could do. Like a shepard's tone which would never reach its crescendo.
This cacophony of flesh and moaning and whimpering soon gained lyrics, and it consisted only of begs and moans for his great uncle Ford to join the symphony.=
“Please please please Ford Ford Ford grunkle Ford I need you I need you Ford Ford-
-Ford!”
The old man pretended that he wouldn’t find what he thought he’d find, up in the attic. Dipper was in danger, that much was obvious, but he didn’t want to accept the reality quite yet.
He knew what he would do in that reality.
But much like the wind and the rain, one cannot wish away the world they find themselves in. Ford realised this as soon as he looked through the wide open door, seeing his nephew with his shorts around his ankle and his shirt pulled above his nipples all the while furiously masturbating and fingering himself.
“Ford Ford please I need you I need to cum I need to cum please Ford please please please–” Dipper was nearly yelling, though it was clear the boy was completely oblivious to his presence. Ford pulled back.
“Okay,” Ford said to himself “if I leave now, maybe I’ll be able to find something to suppress whatever this effect is.”
He once again looked at Dipper. There were tears in his eyes. God he was so cute, he’s literally beg-
“I’ll… I’ll have to take him with me to the lab. He can’t be found like this.” Ford said, and with equal amounts of trepidation and fear he walked in.
This time, Dipper’s eyes turned to Ford. Still masturbating, he tried to move forward to the old man.
“Ford you’re here please I need you I need you I want you Ford please–”
Carefully, Ford lifted up his great nephew. As soon as his hands touched Dipper's skin, Dipper moaned.
“Oh yes yes please Ford I need you take me please!”
“Shh Dipper, grunkle Ford will make it all better. Just be quiet.”
Dipper nodded, stopping his begging but not stopping his masturbation. Ford looked at him, realising just how hard he is and just how badly he wanted to bury it inside of the little boy in front of him. Then, Ford made the mistake of looking in Dipper’s eyes. Those normally oh so innocent eyes, full of lust for him. For him, and only him. Isn’t this what he’s always wanted? And now Dipper was right here, pleading, begging for him to get fucked by Ford.
How could he deny himself the opportunity?
They made their way downstairs really quickly. There was a mat rolled out on the floor, for late night research sessions. This was very similar, in a way. Ford threw Dipper on the mat before looking down at his nephew with lust in his eyes and laboured breathing.
“Please grunkle please fuck me I need it I need it I need it please!”
Ford sighed, as he unbuckled his belt. “I’m sorry, Dipper.”
His massive cock fell out of his pants, and Dipper gasped. Ford could swear he saw his mouth water at the sight. Dipper sat up on his knees, trying to get closer. Ford grabbed the back of his head and forced it against his member.
Instantly, Dipper started slathering it with kisses and licks, pulling moans out of his grunkle. God, when did he get so good at using his mouth? Has his sister been teaching him tricks? He shook his head, what was wrong with him? He was using his nephew like a fleshlight and now he was thinking about Mabel too?
He looked down again. Dipper was still just sucking and licking it, and it started to work him up.
“Are you ready for more, kiddo?”
Without waiting for a response, which he was sure would be an enthusiastic yes anyway, he grabbed Dipper by his hair and forced his member inside his little mouth.
It was heaven. So warm and wet, like it was made to take his cock. Dipper, for his part, was gagging heavily but still forcing himself down as far as he could. He was so eager, he’s always been so eager to spend time with his grunkle. Why would this be any different? Why couldn’t they just keep doing this forever?
Dipper seemed to have some trouble getting down to the base, so being the helpful great uncle that he was, Ford forced him all the way down to the base. He held him there for 2 seconds. Dipper made no attempt to pull back, despite clearly choking on it. Ford can feel himself getting close. He pushes Dipper off, who lands on his back. After catching his breath for only a second, Dipper tries to get back up again.
Ford pushes him down.
“Dipper. Spread your legs.”
Quivering, Dipper obeyed.
His asshole was still lubed up from fingering himself and Ford’s cock was still wet from the blowjob. So rather than grabbing lube, Ford decided to simply go for it. He leaned over, positioning his cock over the entrance. Dipper's begging was silenced by a finger over his lips as Ford whispered in his ears.
“Dipper, I am so sorry, but I am going to make you mine. I can’t hold back anymore.”
Without any other warning, he thrusted inside.
It would be charitable to say that Dipper understood what was going on. He knew that he was horny, that Ford was here, and that’s all he really cared about. He wasn’t even aware of the fact they had moved to the basement.
Ford whispered something in his ear. He simply drooled and nodded as he tried to get back to Ford's cock.
Suddenly, there is a stinging sensation of pain. In that singular moment, Dipper realised how fucked up the situation he was in. The next moment was pure pleasure and he stopped caring.
His grunkles massive cock, hilted inside of him. He could see it bulge out his stomach, and Dipper let out a primordial cry as he came. Cum spurted from his twitching cock, covering his belly with it.
It was the most wonderful feeling in the world.
Then he felt the cock inside him begin to thrust inside of him, and the pain returned. In fact, whatever had caused him to feel like this clearly stopped once he came, but his uncle was still fucking him. What, what was going on?
“G-grunkle Ford? Wh-where are we? What are- ow, stop, that hurts, no stop!”
Dipper's pleading fell on deaf ears as his grunkle kept going.
“Please please stop I don’t want this!”
There was a single moment's hesitation.
“Dipper, I-” Ford started, and stopped. Then he kept thrusting. “I can’t stop, you feel too good, so good, you have no idea how long I’ve wanted this. I’m sorry Dipper, I am so so sorry.”
Dipper felt his eyes tear up as the onslaught continued. His body betrayed him, as with each thrust the pain became less and the pleasure became greater.
At one point he even started to buck his hips against his uncle’s efforts, unable to contain himself. The frantic begging from earlier was now replaced with soft moans and sobbing, but Ford didn’t let up.
In fact, the speed increased. Thrusting more frantically, Dipper could feel Ford’s cock twitching inside of him. He hated how good it felt. He could feel his own pleasure increase too, rising and rising.
“Dipper, I- I’m gonna cum!”
“AAAAHH~!”
Both came at the same time, and the last thing Dipper felt before collapsing was getting filled by his great uncle.
It felt absolutely amazing.
When Ford came to, the first thing he saw was the sight of the inverted moon surrounded by the shining formulas which make up the night sky of his dream realm. He knew exactly why was here.
Sitting up revealed the expected, but still shocking sight. Dipper was here too, stuck in a cage. Naked. On top of that cage sat Bill, sipping a cup of tea.
“Y’know Sixer, most pine trees are full of sap. Not this one though, ha!”
“Bill. I knew this was your doing.” Ford stood up. He noticed he was naked too, and conjured a set of clothes for himself.
“Aww, not ready for round two yet? Pine Tree over here is, arentcha?” Bill's body contorted to look at Dipper. There were still tears in his eyes.
Dipper looked over at Ford. “What- what's going on?”
“You leave Dipper out of this!” Ford shouted.
“Leave him out of it? Sixer, he’s all there is! That’s like leaving out your heart, or your brain. Not like you have much of either though, ha!” He floated up, and circled around Ford. “That was only the sample though! Free trial is up. If you want more, I’m afraid you’ll have to make a deal.”
“F-Ford? What is he talking about? What’s going on?” Dipper crawled towards the bars. There was a look of betrayal and hurt in his eyes. Ford wished that wouldn’t make him so hard.
“So Sixer, what’ll it be? A small deal with yours truly, or a lifetime in the slammer?” Bill’s hand lit up, waiting.
That is when Ford realised the truth of the situation. If he went out of here without making a deal with Bill, it would be impossible to hide what he’s done. He’d be locked up, and Bill would be free to do as he pleased. He could still win.
Ford swallowed.
“Ford? Grunkle Ford? No no no you can’t! Please, I wont tell I promise, you can’t trust him!”
He casted one last look at his nephew. Once he shook Bills hand, he doubted Dipper would mind much. He was silent, but his eyes said it all. Sorry, Dipper.
Then, he turned back to the demon in front of him.
“So? What’ll it be? Time’s running out!”
He took a deep breath.
“It’s a deal.”
They shook hands, and all was engulfed in flame.
