AN: I do not own Gravity Falls or any of the character. I'm not that cool.

Crack

"What was that?" Dipper Pines asked no one but himself.

Crack

Dipper whipped his head to the other side of the clearing, and held very still. Out in the woods around the Mystery Shack one couldn't be too carful. With gnomes, trolls, dinosaurs, and other monsters about, he was glad to have his great uncle Ford's journals with him. Even if, at this point, Dipper had contributed just as much to them as Ford did.

That was what brought him out in the first place. With Gruncle Stan and Ford off on their fifth expedition to the pacific ocean on the Stan 'o War II, Dipper was left to continue his uncle's research. Which he was happy to do. It was a good distraction from thinking about the future and what that would bring.

He and Mabel had just finished their senior year of college, and were spending the last summer before adulthood in Gravity Falls. Soos still let them spend their time there in the attic of the Shack. It was the same as when the twins were twelve and spent their first summer with Stan. After ten years, the exhibits were different, and Soos had updated the merchandise, but it was still just as much a tourist trap as ever.

Which meant that Dipper needed a break from it just as much as he had when he was a kid. Mabel was helping with the gift shop today since Wendy had a real job as a lawyer now, and Soos was being Mr. Mystery. Dipper was not needed for this bus load, so he took the opportunity to go search the clearing for new clues about a possible new species living in the woods—snap—all alone.

He reached for his shrink light. He heard some more rustling in the woods behind him. Placing his thumb on the switch, Dipper stood up, spun around, and pointed the flash light at…

Pacifica.

"Watch out, Dipper!" She shouted as she held up her hands in defense.

He let out his breath. "It's just you. I thought you were a multibear or something." Relieved, Dipper lowered his "weapon."

"If I was a multibear, you would be singing 'Disco Girls' by now," She replied with her hand on her hip and a smirk.

"Haha. Yes. Very funny." Sarcasm always came easy when he was around Pacifica.

She laughed, and Dipper's heart did a flip. That was another side affect to having Pacifica close. After helping her banish the ghost in her families mansion, he realized that their was a lot more to Pacifica than just the shallow bitch mask she put on for the world. Every summer since then the Pine twins and Pacifica Northwest would hang out and soon became great friends.

And then, suddenly one summer, Pacifica was not the spoiled rich girl who was distraught by having only one pony now, but the gorgeous blonde woman who's smile did funny things to Dipper's insides. But Dipper never did anything about it because he was sure she thought of him as just the geeky guy who came to town every summer and would text the rest of the year. Even if Dipper had grown up himself since they first met. He was no longer the boy who squeaked when he fanboyed about the author and had noodle arms, but a tall man with broad shoulders who could actually lift heavy boxes and only squealed under the most exciting of circumstances.

"What are you doing out here?" Dipper asked. It was a bit strange. Not that Pacifica never came out with him to look for clues. Ever since the ghost and weirdmaggedon, she had developed an interest for the mysterious nature of Gravity Falls, but she rarely came out by herself. She usually met him at the Shack and they would go out together.

"I was at the Shack and Mabel said that you were out here. I needed a break from my parents so I thought I would find you." That wasn't hard to fathom. When Bill was defeated and the Northwest family lost their fortune, Pacifica had become her parents ticket to that life again. They always pushed her really hard to get into a good school, a good program, a good job, and a good salary. Pacifica's start date for her job as a PR rep for a new tech start up in Portland didn't start till the end of the summer, but her parents kept nagging her to get the date moved forward. Along with the job, Pacifica was getting a large signing bonus. Her parents would get most of it. Which was fine with her because after getting used to her new life in the middle class she realized she didn't need all that stuff, just some of it. Clothing would always be a weakness, and shoes. But she only needed one closet, not three, and it was ok if she had to walk across the hall to the bathroom instead of having one in her own suite.

Pacifica sat cross legged on the ground next to Dipper's backpack and leaned back. "What are we looking for today?"

Trying not to get distracted by her tanned legs in their denim shorts, Dipper sat down again. "I don't know yet." He grabbed his magnifying glass, and handed it to Pacifica. "If you look in the grass here, you can see tiny prints in the dirt."

Pacifica scooted closer to Dipper and leaned over to look at the ground, resting her arm on his knee. Dipper stopped breathing.

"Yeah," she drawled, distracted by her thoughts. "They look like little dog paw prints. Maybe they are a new breed of chihuahua?" Pacifica snorted at her own joke as she sat back up.

Remembering how to breath again, Dipper snorted right back to cover up his awkwardness. "Instead of teacup poodle, it's a teaspoon poodle."

Pacifica laughed, and Dipper joined in. He couldn't help it. Her laugh was catching.

"So how are we going to find it?" Pacifica asked when the laughter died down.

Getting serious again, Dipper proposed his plan. "I have micro cameras all over this clearing in the grass, and am setting up a trap. Or was when you showed up."

"Do you want help?"

"Sure. You remember those traps we set four summers ago?"

Pacifica thought for a moment. "The ones we used to catch the three eared rabbit?"

"Yep. Same thing but smaller."

"I can handle that." She shot him a cocky grin.

He gave her one right back. "Then lets get to it."

They spent the rest of the afternoon setting tiny traps, and talking about whatever came to mind. Pacifica was especially interested in Dipper's job at the quantum physics lab in Portland. "We will be in the same city!" she exclaimed.

From there, Pacifica asked what quantum physics was and how he was studying it. Dipper explained he was working with time travel. People usually just zoned out at that point in the conversation, but Pacifica actually seemed interested in how it was going to work and when he thought she could come to his lab to see it in action. "Mabel doesn't even want to come to the lab," he warned her.

"She's not as smart as I am," she said like it was an obvious point and he was dumb for not seeing it. "Or at least smart in a different way."

"Good point."

Then it was Pacifica's turn to explain her job and how she planned on increasing the start up's noticeability. What ever that meant. Dipper noticed, though, that she wasn't super into the topic. "Are you happy with the job?"

"Yeah, I guess. I mean, it's a great job and it pays really well. Plus I have benefits, which is nice because I won't have to rely on my parents for anything. But…" she trailed off and finished the trap she was setting.

"But thats not what you want to do." When Dipper looked up, he could see Pacifica angrily swiping a tear from her cheek like she couldn't believe it had the audacity to squeeze out of her eye.

"Not really, no." She tried to chuckle through her sadness, but it didn't work very well. "But you know my parents."

Dipper stood up, walked over to her, and crouched down to give her a hug. She turned into him, and wrapped her arms around him. Pacifica held tight for a few moments, and then pulled away. Without looking at him she mumbled, "Thanks."

"No need to thank me, ma'am." Dipper had stood back up and to give Pacifica some space. "Just doing my duty."

Pacifica smiled up at him. "So anyway, I think that was the last of them."

She did that sometimes; would get sad and then pretend it never happened. Dipper was happy to be their for her-he had been doing it ever since they became friends and he realized that her parents were major dickweeds-but ever since he started to have feelings for her, it would hurt that he was still stuck at the friend zone when he wanted to be in the more-than-friend zone.

Dipper looked around the clearing, silently agreeing not to talk about it anymore. "Right. So next phase: waiting. The best vantage point is in the tree over there." He pointed to a large tree with thick limbs that would hold both their weight, and the treehouse that Dipper had built a few summers back. "House" was a generous term. It was more like a platform placed in a cluster of branches.

"How long is the waiting going to take?" Pacifica looked at him skeptically.

"Um…I don't know…" Dipper rubbed the back of his neck and readjusted his hat. He still wore his white and blue pine tree hat from when he was twelve. The fact that it was still intact and only have minor damage to it was a testament to its good luck.

"Well, I'm not going to sit there all night." Dipper was disappointed, but tried not to show it. "It's hard and cold. Plus I doubt you brought food with you." Dipper hadn't even thought about food. "I'll be back." And with that, Pacifica turned around and set off back to the Mystery Shack.

"Ok…" Pacifica could be so confusing sometimes.

While she was gone, Dipper climbed in his tree "house" and set up the monitor for the cameras, which ran on an interesting substance he had discovered in the spaceship. He was sitting in it when, about an hour later, Pacifica came back with a big duffle bag. She dropped it at the bottom of the tree, and Dipper climbed down. "What's in the bag?"

Pacifica unzippered it and Dipper saw blankets and pillows from the Mystery Shack. "I didn't want to be cold and uncomfortable the whole night. And there is food, too. Mostly snacks, but I had Mabel make us some sandwiches."

"Awesome. I love snacks and sandwiches!" Dipper rooted through the bag and found a sandwich. "I didn't even know I was hungry until now."

Pacifica laughed. "Your welcome."

"How about I get in the stand and you throw the stuff to me."

"Deal."

After all the blankets, pillows, and food were up, Pacifica climbed up next to Dipper. It wasn't a very big space so they were very close, but the blankets made it quite comfortable and since Dipper had set up the platform with a limb for a backrest, they had a place to rest their pillows.

"Cool setup, Dipper." Pacifica noticed when they were both settled in and had a sandwich. "We can see all the traps from here, and the camera feeds are coming in nicely."

Dipper blushed as he took his hat off to get more comfortable. Luckily it the sun was setting so Pacifica couldn't tell. Hopefully. "Thanks. I did something like this when I was in college. We were studying dear eating habits."

"Neat. All I did was write papers, take tests, and party."

From there, they discussed their last year of college, whether or not Soos was going to propose to Melody, and had a very heated debate about whether or not cheese cake was the best dessert as the sun set and the moon rose high in the sky.

Dipper was just about to make a solid case for banana cream pie when Pacifica suddenly leaned into him, brought her face an inch from his, raised her arm, and…pointed to the screen. "What was that?" she quickly inquired.

"Uhhh…" Dipper responded unintelligibly. The scent of Pacifica drove all other thoughts from his mind. All he could do was stare at her beautiful blue eyes in the moon light, and try to ignore her breasts pressed against his arm.

Pacifica turned her face toward him with an eyebrow raised as if to say why are you being such an idiot? Then her eyes met his, dropped to his lips quickly, and shot back to his. It was as if she hadn't even realized they were so close until that moment. After a second of hesitation, she closed the gap and kissed him.

Dipper was so shocked that he didn't even move. Was Pacifica actually kissing him? What should he do? What did this mean? Dipper hadn't made a plan for what to do if this happened!? Before he could even think of what to do next Pacifica pulled away, her eyes wide as the full moon out tonight.

"Oh my god, Dipper. I am so sorry. I don't know what came over me. That was so stupid. I'm such an ass. Just forget it happened." She sighed and buried her face in her hands.

After recovering from the shock of the kiss, Dipper had to wait for his brain to catch up with the shock of Pacifica saying it was stupid. With no plan in his pocket for this situation—he never would have thought she would kiss him—he had to listen to his gut. He hoped his gut would get it right. "Don't apologize. You're not an ass. I am. A beautiful girl kisses me and I can't even think fast enough to kiss her back when I had the chance to."

Pacifica peeked though her fingers at him. "You think I'm beautiful?"

It was Dippers turn to raise an eyebrow at her. "Of course I do. How could I not? Your smart, sweet, funny. Your eyes are the perfect shade of blue, and for some reason, I even like that you are more sarcastic than I am. You make me think, and try harder."

Lowering her hands, Pacifica smiled at him. "I am better at sarcasm, aren't I."

"And humble," he chuckled. Dipper brought his arm out and pulled Pacifica into a hug. She hugged him back.

"I think you're pretty great, too," she mumbled into his shoulder. "I have for a while." Pacifica pulled back, took a deep breath, closed her eyes, and plowed on. "I don't know when it happened, but I guess it has been for a few years. I really like you. I can't believe I'm even telling you this now. I was not planning on having this conversation tonight, or ever, but I guess it's a good thing since you think I'm beautiful and smart and other things. I know I'm not the easiest person to be around all the time because I can be kind of a bitch, but we are still friends so you can at least tolerate me—"

Dipper kissed her. He kissed her. She was ranting and he couldn't get a word in. It was Pacifica's turn to be shocked. He pulled away. "I like you, too. So much. I never would have believed you felt the same things for me. I'm a geek and you're so…not. But I'm not going to question it. I'm just going to kiss you again before you wake up and realize it's me here, and not someone who actually deserves you."

He went for another kiss, but Pacifica stopped him. Dipper tried to keep the hurt off his face, but didn't so a very good job. "No Dipper," she explained. "You're wrong. I don't deserve you. You are smart, funny, nice and so hot." Her cheeks flared bright pink, even in the moon light. "So just don't undersell yourself."

"I'm hot, am I?" Dipper lifted the right corner of his lips.

Pacifica laughed. "Great, now you're the conceded one."

Dipper smiled, placed a hand on the back of her neck under her hair, and pulled Pacifica into a real kiss. This time they were both fully prepared, and had zero shock to get over. It was a slow kiss, soft and testing. Pacifica moved her hands to his back, while Dipper ran his other hand down her waist to settle on her hip. She pulled him closer and deepened the kiss. It moved from testing to passionate quickly from there.

No longer slow, Dipper was gaining courage, and pulled Pacifica into his lap. She straddled him, and moved her hand to around his neck and in his hair. He held onto both of her hips when she lightly pulled on his hair to get a better angle for the kiss, eliciting a deep moan from him. Dipper pulled back for a moment of air, and Pacifica moved on to his neck, placing wet kisses from his pulse point to his ear.

When she got to his ear, he went crazy, and forgot about everything else. It was just him and her and no one else in the world. Dipper moaned even louder, and went back to Pacifica's soft lips. He ran his tongue over them, and she opened her mouth to let him in. Dipper pulled her bottom lip in between his teeth and lightly bit her. Pacifica crooned and pressed every part of her against him.

Dipper lost just about every ounce of control he had left. He continued to kiss and play with her lips as he pulled her hips closer to him. He had been hard for quit some time now, but it was officially fully erect now. Pacifica ground herself against him and he could only focus on that. He rest his forehead against her shoulder while he growled. She moaned as she held onto his head, her hand in his hair on top of it. Dipper moved his hands under her purple shirt, and up her back. Her skin was so smooth, and toned.

"Pacifica," Dipper panted. "Either we stop now, or I can't promise I can later."

She groaned in frustration. "Shit, Dipper." Her voice had gone deep and husky. "That was insane." She rested her chin on his head and tried to catch her breath. "But you're right. We should slow down. A tree house isn't the best place to have sex for the first time."

Sighing, Dipper sat up, and looked into Pacifica's eyes. They were half-lidded, and bright with lust, longing and something else he couldn't quite figure out but was excited to investigate later. He was sure his were a mirror of her's, but brown. He kissed he one last time, and said, "Correct. If we get to that point, I would like it to be a bit more magical than in a tree house hunting for mysterious fairy sized dogs. And when I say magical, I mean romantic. No literal magic involved."

Pacifica gave him a sleepy smile. "Thats good. Because when we get there, I would appreciate rose petals and candle light. Not persepshroom powder and a visit from the Love God."

"Deal," Dipper yawned. He readjusted himself, and Pacifica lay her head on his chest. After wrapping his arms around her they both fell asleep surprisingly fast.
