Hey guys! I'm CBT, and this is a BillxDipper fanfic! Please if you don't like gay things, I'm sorry but you just parked in the wrong place. Dipper is 15 years old and Bill doesn't have any specific form or age (maybe between 12 to 25 years, you will understand later.)

The story happens 3 years later after Stanford's return.

And so this fanfic will be really cute, fluffy, smut, sexy, drama and such! Not gore, violence, maybe some bad words, but nothing further than a little smack on that booty!

HOPE YOU LIKE IT!

-Moving?! Why are you leaving me?!- Mabel cried loudly. She was knitting a new sweater for waddles in her and Dipper's room. She was looking amused at Dipper.

-Mabel please- Dipper said with a little giggle. -I'm not moving! I'm just changing rooms in the same house... I'm not leaving you.-

-B-but...- Mabel leaned her head quickly and sighed. -But…- she looked at Dipper. – You are going to allow me enter to your room right? - She smiled at him.

Dipper took his last luggage bag. –Yeah, But... just sometimes. -Dipper opened the door and stopped. -But please... knock the door before coming. - And so he leaved, leaving Mabel staring to her own room.

-Well... on the bright side, I can decorate the whole room with posters- she smiled.

Dipper was walking to his new room. He opened the door and saw his two great uncles inside.

-Hey Dipper! Come in! - said Stanley.

-What are you doing in my bedroom? - asked Dipper while heading to the room.

-Hey, this was my bedroom kid! I'm allowed to take a quick peek before leaving it to you. I even helped you to move here. Now let me remember all those old memories. - answered Stanford.

Dipper left his bag on the top of his bed. Dipper smiled at the thought of the attic room looking bigger than before. Actually, it had space, now that he's no longer sleeping there it would be great to his sister. He even bet she was going to decorate the room with poster of "handsome" guys.

-Dipper, this room now is all yours. Use it well boy, I think you will have fun! - said Stanford with a big smile. Dipper just laughed nervously. If only he knew...

-I know you're growing and all that stuff but I still don't get it... Why so suddenly you want to have privacy? I mean... Why now? You tried before, but you returned to your old bedroom- questioned Stanley looking serious.

-That's not true. A-actually, I've been thinking of my own privacy since...- Dipper scratched his cheek with shyness. -You know... Now that Great Uncle Ford is here, I have been staying up late and bothering my sister so is better to be on my own world by myself.-

-Oh, I didn't think about that. I've always worked in the same room as Stanley, I thought he was okay with me and my experiments but even so we had some hard times.- Stanford said looking at his twin brother. Stanly just looked at him serious and left.

-I think Dipper is even better with his sister than you were! He thinks about her feelings, not like you! - He said loudly.

Stanford looked at the door annoyed. He started walking outside while arguing loudly. -Wow, looks like SOMEONE doesn't want to get over the past so easy! - He said annoyed. -And just to let you know, you called yourself "sister"-

-Pffff, what?! I DIDN'T! - shouted Stanley.

Dipper closed the door of his now new room. He sighed annoyed thanks to his two great uncles. He can still hear them arguing. He sat on his same old bed next to the bag and looked around to see the room. The room was clean and organized, it looked different and bigger than before.

-Knock, knock! - sang a voice coming out of the door.

Dipper stood up, walked quickly and opened the door. He looked at the 15 year old blonde boy who was staring at him with a smile. Dipper smiled quickly and took him inside his bedroom.

-You made sure no one saw you, right? - asked Dipper with a little bit of anxiety.

.-Oh come on, Pine Tree- the 15 year old boy got closer to him. -I know how to play...- in a blink, the 15 year old boy transformed in a 18 years old. -Hide and seek. - He teased with his now deep voice

-Not now Bill. My two uncles were just here moments ago and they could come over anytime. - Dipper said with a little blush, ignoring the teasing from Bill.

-Hey, hey, no problem my little Pine Tree! - Bill returned to be 15. -I got a plan if they see me! - He stood in front of Dipper and took a long breath. -HI! NAME'S WILLIAM! I'M 15! DON'T SUSPECT ON ME PLEASE! - Bill said loudly and fast. Dipper gave him a sarcastic face.

-Bill, if you tell people "don't suspect on me", they are definitely going to suspect on you. - said Dipper looking at him like he had just told a bad joke. -Besides, even with or without you telling them that, they would suspect on you and me anyway. They had never seen you before in your human form, so that gives us advantage in this situation. We can just say that you're a friend of mine.-

-Yeah, and that's why you have to introduce me as William! - interrupted Bill.

-BUT...- Dipper said louder to make Bill shut up. Bill just rolled his eyes and sat in the bed.

-But, what?-

-But that can only work if they catch us talking or doing something that normal "friends" are supposed to do.- Dipper said emphasizing the word "friends" with his two fingers.

-What if they catch us making out, huh? - said Bill with a big grin. -Or maybe... I don't know... having sex or something?-

Dipper blushed a lot but tried to keep looking at him with a serious face. -No, that won't happen. I don't want to explain the whole thing, explaining this and that. It's troublesome! - He said a little bit annoyed.

Bill sighed. Then he moved back on the bed until he felt his back press the wall. Then he opened a little bit his legs and made a little space in front on him. -Come here, Pine Tree. Less talking and more action!-

Dipper hesitated. What if someone entered the room and looked at them in that position? He really hated to talk about his personal life. Dipper blushed and went to sit where Bill told him. Bill let his arms hug Dipper's waist and his chin rest on his shoulders. Their legs intertwine with each other. Bill moved his head, making his nose brush against Dipper's neck. Bill moved his head gently as his nose made little circles in his neck making Dipper shiver by the soft touch. Bill then stopped slowly and moved his head to make his lips meet Dipper's neck.

-Your skin is soft, Dip-dop. I love it. - whispered Bill. Dipper could feel how the lips moved against his neck, making him blush even more. Bill started giving small pecks to his neck. Dipper giggled a little bit, it made him tickle. They felt in the mood for more until...

-DINNER IS READY, KIDS! GET HERE RIGHT NOW, OR ELSE I'LL EAT YOUR FOOD!- a shout from downstairs was heard all over the shack.

-Gosh, I almost forget it. - He turned to face Bill and give him a small quick peck in the lips. He stood up and tried to tidy up his clothes. He walked towards the door and before leaving he looked at Bill and gave him a smile. -See you later. - And left.

Bill kept staring at the door like a fool. -This kid made me so weak and changed me...- He covered his face with one hand. -Damn it, Pine Tree. I'm fucking in love with you. Now it will be even more difficult to me to live on my own if something ever happens to you...-
