Dippers POV

.

.

I was walking in the forest when I heard a way to  familiar voice.

B: "Hey there pinetree~"

I freeze and look around. "Shit where is he I can't let him know" I thought as a kept walking through the forest.

B: "Know what pinetree"

D: "N- Nothing!"

I start to run until I bump into someone.

D: "I'm so so so sorry!" I say looking down

B: "It's ok pinetree~"

I froze and looked up to see a very good looking guy with blond hair, a yellow tailcoat, a white undershirt, a bow tie and a top hat, but what memorized me the most was his eyes, well his eye since one of them were covered, it was a golden yellow.

B: "You know staring in rude pinetree~"

Then I realized, it was bill!

D: "Get out my head!"

B: "Only if we make a deal"

D: "What do you want?"

Bill's POV

I was surprised when he said that, he would normally say "No way bill! I'm not making another deal with you after what you did!" then I would threaten him.

B: "I want you for tonight and tomorrow and you will help me be more human!" I said cheerfuly

D: "And what do I get?" he asks

B: "Well what do you want?" I ask responding

D: "I want..."

He pauses and thinks for a bit, I go into his mind.

"I really want him! I want to date him and kiss him, I loved him since the weirdmageddon but I hid my feelings so I wouldn't be killed"

My human face heats up for some reason.

B: "W-Well?" I stuter. I never stutter!

D: "Did you just stutter?!" he looks at me in shock.

B: "Yes, so?!" I ask annoyed.

D: "Sorry! Umm I know it's gonna be weird but-"

B: "I'll date you pinetree!"

He looks at me with happiness, my new heart skips a beat.

"He looks so cute! Why did I try and kill him again?" I think.

D: "Thank you so much!" he cheers

He hugs me them kisses me, I kiss back.

Dippers POV

The kiss was getting very heated.

M: "Dipper where are you!?!"

D: "We need to go now" I whisper shout at bill.

He nods and we are in his bedroom now.

Mabel POV

I was looking for dipper, it was late and he hadn't came back for dinner. I saw a clearing so I went there and saw a mark on the floor.

It was a pinetree and in the background was a triangle, there was also a note. It said

"Me and pinetree made a deal, don't worry he will be back tommorow, if he wants to come back"

"No! Bill took him!"

I run back to the shack.

"How is he back?! We killed him!"

I ran into the shack and Ford and Stan was there.

S: "What's wrong mable?"

I huff.

M: "Dipper made a deal with Bill"

F: "He did?! No, he isn't that stupid!"

I hand Ford the note he growls.

F: "We just have to wait"

3rd Person POV

With bill and dipper

Dipper and bill hugged again.

D: "So what do you want to do?"

Bill smirk and snap his fingers, dipper was on the bed naked. He didn't seem to mind.
Bill snapped his fingers again and he was naked and his extremely big rock hard dick was out. Dipper was scared of the size.

B: "Don't worry pinetree you will be fine"

Bill went over to a draw and pulled out a normal sized vibrator.

B: "Tonights gonna be fun"

Bill chuckled and went over to dipper, dipper was already turned on his stomach.

B: "Eager much?"

Dipper nodded and bill spat on dippers entrance making him shiver.

Bill then put the vibrator in dippers ass and turned it on to the highest setting earing a load moan from dipper.

Bill flips dipper over and kisses him roughly while stroking dippers dick.

Dipper moaned into the kiss and was begging for air.
Bill pulled away and started to suck dippers member, dipper moaning even louder.

Dipper cummed in bills mouth and started panting, he was still a bit hard.

Bill then took out the vibrator and positioned it at dippers entrance.

B: "Can I pinetree? I don't want to do this without your concent" bill asked

Dipper was a bit surprised at bills words. He slightly nodded.
Bill slowly stared to enter dipper, dipper yelped.

B: "I'll be slow darling"

He put his member in dipper slowly until it was all in. He let dipper adjust for a couple minutes until he spoke up.

B: "Are you ok sweetheart?"

D: "Yeah it just hurts a bit, it isn't my first time bit is still hurts"

B: "Who was the first guy?"

D: "My ex"

Bill just nodded, dipper started to move his hips signalling that bill could move.

Bill slowly thrusted into dipper, dipper moaned quietly.

D: "Go f- faster" 

Bill increased his speed until his thrusting was at a somewhat normal pace.

D: "Yo- You're so big bill~" Dipper moaned out

B: "And you feel so good pinetree" Bill grunted out.

Dipper was reaching his climax once more.

D: "Go faster~"

Bill smirked and thrusted into Dipper very fast. Both of them cummed at the same time, bill slowed down his thrusting and then pulled out. He snapped his fingers and the pair were wearing their normal sleep wear.

D: "I love you bill"

B: "I love you to pinetree"

D: "Do I have to go back any time soon?"

B: "No, you can stay as long as you want"

D: "Could I stay here for a week with you?"

B: "Of course darling, let me send a note to them in the moring, right now i very tired"

D: "So am i"

The two lovers drifted of to sleep, the dream demon gave the younger one a nice dream.

The next day

Dippers POV

I wake up in bills arms. "He's so cute" I think. I try to get up but bill hugs me tighter.

B: "NoOoooOooO" He whines

D: "I need the bathroom bill come on"

He lets go and groans and flips to the other side. I go to the drawers and pick out some jeans, white top, navy blue jumper and some black socks. I walk into the bathroom and have a shower. When i finish i walk out and bill is still sleeping.

"I'll make him breakfast!"

I walk out the room and look around, its a nice small looking house. I find the kitchen with ease and look for any ingredients, I find stuff to make pancakes. I make the batter and fry them, after i put a stack of pancakes on a plate and put the plate on a tray. I make some coffee and grab some yogurt and place it on the tray.

I walk upstairs into the bedroom and open the door.

D: "Bill sit up, i made you food!"

He sits up and looks at what i made him. I gave it to him

B: "You didnt have to~"

D: "Yes i did!"

I watch as he eats the food happily.

B: "You're a very good cook!"

D: "Thanks!"

He finishes eating and makes the stuff dissapear.

B: "What do you want to tell your family?"

I think about it for a second.

D: "How about 'Hi stan,ford and mable. Im ok dont worry, bill hasent hurt me and dosent intend on doing so. I'll be staying here for a week with bill. I also have something to confess, if you didnt know already im bisexual and I also love bill alot! I started loving him since weirdmegadon. If you dont accept me its ok, Sincerely Dipper Pines' "

Bill nods.

B: "Its been sent to them!"

D: "Thanks Bill"

B: "No problem pinetree"

D: "You mean everything to me, your my sunshine, the light of my life, i have no clue what my life would be without you"

Bill blushs at my comment

B: "I adore you pinetree, you are the reason i've changed, the reason i want to be a better person. I would be so lost with out you"

Now it was my turn to blush.

D: "I love you so much"

B: "I love you more~"

I huff knwoing this will go no were.

Mable POV

At the shack

I walk down stairs to see Ford crying and Stan conforting him.

M: "Ford whats wrong?!?!" I say running up to him

F: "Dipper" He couldnt get anything else out and just sobbed.

I saw a note, i saw at the end who it was from and it was from dipper.

When i read it i was confused "He loves Bill?" I was so confused until the realization hit me like a truck.

"We have to leave in 2 day... and he wont be able to come back since bills powers are limited to gravity falls and there is only one bus that comes to gravity falls and the nexted one is after the 1st term"

"CURSE YOU DIPPER AND BILL!!!!"
