Dipper opened his eyes and the first thing he saw was the dull ceiling. He was in the room in the Mystery Shack he had claimed as his own roughly five years ago. The room had once belonged to his great uncle Ford before he had disappeared into an alternative dimension for thirty years, but after his untimely reappearance seven years ago he found he preferred the new quarters he had made for himself in the basement. It was more convenient anyways, he was near his laboratory which was also the place he spent most of his time.

The room was dimly lit, scarce rays of light seeped through the curtains none of which, thankfully, landed on Dipper. He sat up with a groan and stretched. His back cricked and cracked pleasurably and he sighed as the tension left him. Summer was just about over. Sure it was early august and University wasn't scheduled to start until September but he and Mabel would soon have to leave Gravity Falls and return home.

The summer had been rather eventful. Never in his wildest dreams did Dipper ever think anything like what he had experienced could have happened to him. He began the season by becoming sex friends with a demon that had, seven years ago, tried to bring about the End of the world. At first it was just fun and games. Bill had a fascination with bothering Dipper while he tried to masturbate to porn and one thing then lead to another. He kept their status secret for as long as he could – which happened to be longer than he ever expected. The brunet had thought their relationship would never graduate to anything more at the time but he had been wrong. A little less than a month later, he and Bill began officially dating.

It was a summer romance in every sense of the term. Of course, it wouldn't die with the season – at least Dipper hoped. He was fairly certain he and Bill would continue dating for a good long while. He just wasn't sure how he would explain things to his parents. There was no way they would ever learn that Bill was a demon – Dipper and Mabel both agreed it was best to keep them out of that world – so the problem generally was the backstory they would have to give him in order to create the illusion of normalcy.

He supposed it was a problem that he could deal with later. Mabel would surely help him anyway. He could always count on his twin.

Dipper pushed himself off his bed and scratched his bare chest. He glanced at the clock and found that it was nine in the morning – he had slept in. He lazily pulled on a white shirt that had been laying on the ground for probably far too long. Once he was relatively presentable, he left his room and made his way to the kitchen. The brunet had only stepped out of his room when he began hearing the curses and shouts of his great uncles. It was almost like a morning tradition to have Ford and Grunkle Stan just yell at each other about trivial things. Though he learned to simply ignore the ruckus.

Dipper found his twin sitting at the table, poking at her bowl of cereal with a pensive look. Mabel was so engrossed in her thoughts that she didn't even notice him walking into the area. He took his normal seat in front of her and probed her forehead. She snapped out of her thoughts, surprised by herself and by Dipper who had, to her, suddenly appeared out of thin air.

"Don't strain yourself." He joked.

"Good morning." She huffed.

Mabel seemed a bit bummed.

"What's up?" Dipper asked.

"It's just…summer's almost over." She mumbled.

"Yeah," Dipper sighed, "It was a good one."

"To you." Mabel complained, "You had a crazy summer, you dated a demon and had lots of crazy sex and stuff! I did nothing!"

"That's not true." Dipper said, "You hung out a lot with Pacifica."

"Yeah but," Mabel groaned, "Dipper, I'm nineteen. Ever since I was a kid, I always thought my adult summers would be way more fun than when I was a kid. I thought I would have these amazing summer romances, dating dramas, and just stuff like that. But look at me! I'm still single with no suitor in sight!"

"You shouldn't be so desperate to find yourself a boyfriend." Dipper said and he hoped it sounded comforting, "You'll find one when the time is right. And being single isn't so bad!"

"I'm not saying it's bad either!" Mabel insisted, "It's just how I am! I like being in relationships! I love doing romantic things! I aspire to recreate some of my favourite scenes from my all-time favourite romance novels! I even have a list and nothing's been checked!"

"Okay, so maybe that's a bummer," Dipper conceded, "But does that mean our summer was really bad?"

"Well, yes." Mabel said, "Maybe not just because I still haven't had my romantic break through, but more because we didn't really do anything. Think about it, you hung out with Bill, I hung out with my friends, and when we weren't doing that, we were just helping around the Mystery Shack and working."

Mabel did have a point. Dipper wouldn't go as far as to say his summer was eventless but he could see the lack of adventure it held. Most of their summers had been filled with crazy stories no one would ever believe. Naturally, those dwindled as they grew older and steadily got less involved with the supernatural. There wasn't much of a necessity if your local gnomes weren't planning another coup or a psychotic demon wasn't trying to enslave humanity and bring about the End of the world. Dare Dipper say it, their summers had gradually become ordinary. Uneventful. Dull.

"It's not too late to change that." Dipper said, "I mean, I'm sure we can think of something together."

"But I don't know if I want to try to recreate our childhood." Mabel said, "I've had my fill of perilous altercations with the supernatural, if you catch my drift."

"Hey, who says adventure and fun had to be linked to that sort of stuff?" Dipper asked, offering a smile, "You're right, we haven't really done much of anything this summer. Sure, I had a lot of…fun but it's nothing I can really share with the people back home. So how about we try having some normal adventure? Actually do what kids our age do for once."

Mabel nodded and the two began thinking. It was a bit tough what with Ford and Stan's yelling. Dipper ignored it to the best of his ability as he tried to hone on the common man's definition of normalcy. That was probably one of the most difficult things to do because he had only known madness and chaos as the norm. His great uncle had travelled and lived in an alternate dimension for thirty years, for Christ's sake! He had all but given up when his sister suddenly snapped her head up with a beaming smile.

"The beach!" She exclaimed, "We should go to the beach!"

"You mean the lake near Gravity Falls?" Dipper said, sounding unexcited.

"No! The ocean!" Mabel continued excitedly, "We have a car now! We should drive over to some place next to the sea and just have beach time fun for a week!"

"Sure, that sounds like fun." Dipper shrugged.

In truth, the concept of venturing out for a relaxing vacation by the beach didn't entice him too much. Dipper much preferred exploring a historically rich place and learning about the culture and living habits of people when travelling. Sitting by the beach and occasionally going into the water for a quick swim seemed rather boring, but he kept his mouth shut. If Mabel wanted to go to the beach and seemed excited at the prospect, then he would support and entertain her. This was more for her than it was for him anyway.

"We should also invite people!" Mabel continued giddily. "We could invite Bill."

"I'm not sure he'd want to but I can still ask." Dipper said. "Are you going to invite Candy and Grenda?"

"Nah," She said, "Candy's in San Francisco visiting family and Grenda's in Austria with her boyfriend. I'll invite Pacifica instead."

Dipper's smile faded instantly. "Really?" He asked with dismay.

It wasn't a secret that he didn't like Pacifica. The first thing he had thought of when they'd met her seven years ago was that she was some entitled, pretentious rich kid in every negative way. His opinion hadn't changed much. Pacifica did prove from time to time that she did have a heart buried deep somewhere in her, and she had developed as a person to the point of actually befriending Mabel, but Dipper still hated her. He had a hard time forgiving people when it came to his family. Pacifica had been mean to his sister, had been unjust, and rude on countless occasions when she really had the option to simply be kind and thoughtful. Mabel might have forgiven her, but he hadn't. He supposed it was because she had a bigger heart.

"Yeah, Pacifica's great!" Mabel said with a wide smile. She then winked and poked at Dipper with her elbow, "And she'll be a great wingwoman! Plus she's loads of fun! You'll see!"

"Un-hun…" Dipper said unconvincingly.

"So you want to go book a place to stay now?" Mabel asked, practically jumping with excitement.

"What? You want to leave now?" Dipper asked though he wasn't being serious.

"Sure! Why not? It's not like we're doing anything." Mabel said and Dipper couldn't really argue with that.

"Okay then." He said.

Though he had initially gone to the kitchen to fetch breakfast, he decided it was best not to attempt crossing the no-man's-land that had developed between the two great uncles over the course of their conversation. He followed Mabel out of the kitchen and into her room in the attic. He sat on her bed and she pulled out her own laptop, typing away quickly.

"Do you have any idea where you want to go?" Dipper asked after a long moment of silence.

"How about…" She said then paused briefly as she typed a few additional things, "Newport? It's a pretty short drive and it looks nice. They got a cool aquarium too."

"Sure." Dipper shrugged again and leaned back on the bed.

"Oh look," Mabel said and clicked on a link, "Discount beach houses!"

"Wouldn't a hotel or motel be better?" Dipper asked.

"I don't know but getting our own little house could be awesome." Mabel shrugged as she scrolled through the web page. She then stopped and clicked on an image of a house she liked, "Oh, this one's cute." She said, "It's got this sort of 1950s style…three bedrooms and two bathrooms. And it's 2000$ per week, so 500$ each if Bill and Pacifica are coming."

"That's pretty reasonable." Dipper nodded.

"Should I book it?" Mabel asked.

"I reckon we should ask the other two first before we do anything." Dipper said. "If they say no, we should look for a cheaper option."

"Good plan." Mabel said.

While she pulled out her phone, Dipper took a big sigh and called out for Bill half-heartedly. He always thought it was awkward to do so. He felt a bit like a lunatic speaking to an imaginary friend or one of the many voices in his head. Of course, it was far from that because, typically, after three times, Bill ascended or descended from a blue portal he created. And like any other time, the same thing reoccurred. Dipper didn't understand why the demon bothered keeping his phone if he didn't use it.

The portal opened on the ceiling and Bill fell on his back, promptly winding himself. He gasped and moved his mouth dumbly as he struggled to begin breathing again. Dipper and Mabel hovered around him worriedly, panicking on what to do if the demon couldn't start breathing again. However, Bill eventually did manage to swallow a big gulp of air and then started laughing hysterically.

"Whoa! I've never done that before!" He exclaimed.

"Oh my god, just be careful!" Dipper snapped in frustration.

"Calm down, Pine Tree." Bill said like he was being a buzz kill. "I'm still immortal."

"That's no excuse to keep hurting yourself." Dipper sighed in exasperation. He wasn't sure he wanted to invite the blond anymore.

"So why did you call?" Bill asked and a lecherous smile began spreading on his face.

"Beach vacation!" Mabel chimed happily, making her presence known. "You in or out?"

"Beach vacation?" Bill repeated musingly. "What does that entail?"

"We go to the beach." Dipper said bluntly. "And then we relax. You know, your normal vacation. Just next to a beach."

"Don't patronize me." Bill pouted with a glare.

"We're going to Newport." Mabel continued, "We're going to rent a house that's basically next to the sea. If you're in, you're going to have a pay a bit of the rent."

"How much?" Bill asked.

"500$." Dipper said.

"That much?" He whined, "I was going to buy this expensive thing at the BDSM store! Bucky ordered one in just for me too!"

"Bucky?" Dipper asked.

"The BDSM guy." Bill said, "He's people, Pine Tree. He has a name."

"You can always buy it later." Dipper offered, eager to change the subject, "You are immortal. You got all the time in the world."

"Touché." Bill grumbled, "Alright fine! On the condition I get to share a bed with Pine Tree!"

"Only if you don't fuck every night and are mindful of the other tenants!" Mabel conditioned.

Bill frowned in displeasure. It seemed he wasn't ready to accept the deal.

"It's only fair." Mabel insisted, stretching out her hand to seal it, "And you're not getting a better deal."

Bill still seemed unsure whether he should capitulate.

"She doesn't mean we're not allowed to have sex." Dipper sighed, seeing all too clearly what the demon was struggling with. "She just doesn't want us to be loud and do it every night. We can do it when she and Pacifica are out doing things and we're alone."

"Oh." Bill said extendedly as though he now understood everything. He then grabbed Mabel's hand and shook it, "Then it's a deal!"

"Awesome!" Mabel beamed, "Now I'm going to call Pacifica." She turned to Dipper and asked: "Can you book the reservation for us?"

"Sure." Dipper said, "Start getting ready when you're done with the call. You too Bill."

"But I'm not calling anyone." The demon said.

"You know what I mean." Dipper said as he rolled his eyes.

He grabbed the phone and dialed the number on the web page Mabel had found. Two rings later, an old woman answered. She had a bit of a hearing problem and so Dipper found himself yelling more than talking for most of the time. He asked her three very loud times if the house was vacant for the next seven days and if she could have it ready by tomorrow. She answered yes, took down their names, and accepted the offer of cash payment upon retrieving the keys at her home. He then thanked her before hanging up.

"Good," Dipper sighed, "Mabel—"

Mabel was still chatting with Pacifica on the phone. They had long since bailed on the topic of the beach vacation in Newport and were gossiping about the many teenagers of Gravity Falls. It took him a while to get his sister's attention long enough to learn that Pacifica would indeed be tagging along. He managed to tell her what little information she would need to know and share with her friend before losing her to the conversation again.

"Say…" Bill said hovering over to Dipper, startling him in the process. He hadn't realized the demon hadn't left, "Didn't those two use to…not get along?"

"Yeah, but people change." Dipper said, "I mean, just look at us. You remember how we were seven years ago?"

"Yes." Bill laughed and suddenly became very serious as he said: "I wanted to skin that stupid face of yours and shove bees down your throat."

"A-and now we're dating…" Dipper said with a nervous and forced chuckle. He hadn't really been asking for honesty from Bill in the first place.

"And I couldn't be happier." Bill sang and kissed his human's cheek.

"So did you get your luggage done?" Dipper asked, readily changing the subject.

"I don't own much of anything." Bill reminded.

"Well, I guess we'll be spending most of our time in our bathing suits anyway so it's no big deal." Dipper shrugged.

"I don't own a bathing suit." Bill admitted.

"Really?" he asked, surprised.

"Yeah." Bill said simply, "I've never been swimming before and never thought I would."

"We've got a lot to do so I guess we'll just swing by a store in Newport and buy you one there." Dipper sighed. "Now come with me, we'll shove some of your clothes into my suitcase."

"We're sharing a suitcase?" Bill gasped excitedly.

"Yes?"

"That's so romantic!" He keened happily.

"It's really not." Dipper assured.

Dipper led the way back to his room. He took out seven days' worth of clothes and his two swimming trunks which Bill disapproved of. There was really nothing wrong with them, the demon's disagreement was simply a matter of opinion. He thought Dipper should sport speedos rather than what he actually owned. To Bill, the speedo was the second best thing to come out of 1914.

The suit case was rather big and there was more than enough space to fit what little clothes Bill actually had. Most of them were suits or large sweaters. Dipper made a mental note of needing to take the demon out for some actual clothes shopping some time in the future. He also added to ask Mabel to tag along. She had a better fashion sense than he did. Regardless, there was still considerable space left within the suit case that Dipper knew wouldn't be filled up with the addition of whatever swim wear the demon selected for him. Thus he stuffed in two beach towels and his pair of flip flops before finally shutting it and hauling it next to the door.

"It's like we're a married couple." Bill said with a sort of twinkle in his eye.

"It's really not." Dipper said awkwardly.

"Don't ruin this for me." Bill said.

Dipper smirked and rolled his eyes as he fell back on his bed. "You're really excited about this aren't you?"

"Why do you say that?" Bill asked curiously.

"You're like…beaming." Dipper explained, "It's just…it's something in your voice, the way you say things and the way you sound."

Bill grinned, "Well I'm not not excited." He offered as he hovered over to the brunet and sat on his lap.

"That's what I'm saying." Dipper said and kissed Bill, sliding his hands up his thighs to rest on his waist.

Dipper pulled away but the demon quickly moved back in for more. The kiss that had initially been sweet had become hard and eager as Bill grinded their hips together with lazy movements. The brunet gasped and moaned in the kiss, feeling his pants gradually becoming tighter. The moment Dipper felt the blond grin against his lips, he flipped them over, pinning the demon beneath him. Only then did he see the devious and mischievous look shinning in Bill's eyes.

"I'm thinking dirty thoughts." He confessed.

"You always are." Dipper said before pressing their lips together again.

Slowly, they peeled their clothes from their bodies. Their hands roamed the other's body, feeling every muscle and curve, massaging every sensitive spot with added pressure and teasing pinches. The effect Bill had on Dipper was other worldly. Never would he have ever had sex so early in the morning but here they were and it wasn't even noon.

"Why are you smiling like that?" Bill purred.

"Because I'm happy." Dipper answered. "You make me happy."

Bill blushed and buried his head in Dipper's chest out of embarrassment. "Shut up…" he grumbled.

The rest of the day passed by at a leisurely pace. Bill and Dipper spent a lot of it in bed, holding and cuddling each other in the post-coital glow. But then Mabel barged in, demanding they get their clothes on and help her make her luggage. She had a mountain of clothes she wanted to bring but couldn't and so had the emotionally painful task of having to sort through them. Thus she modelled for them and when she finished making her decision based off their commentary, they gathered beach supplies around the Mystery Shack. And that was that.

The next day, Pacifica was at the Mystery Shack early with all of her things. She stood in front of the porch with big, round shades covering her eyes, wearing expensive clothes that had likely been imported from Europe. There were also four large suit cases sitting next to her in their bedazzled glory as well as a beach umbrella, beach chair, and beach ball. Dipper had to suppress an eye roll. Sometimes, Pacifica just fit the stereotype of a rich kid too well.

"Pacifica." He greeted sternly.

"Hm." She said, hardly sparing him a glance.

It wasn't a secret even to Pacifica that Dipper hated her the same way it wasn't a secret to him that she hated him as well. Their relationship was essentially founded on mutual hatred for each other.

"Pacifica!" Mabel squealed and shoved pass Dipper to throw herself around the blonde. "Were you waiting long?"

"Like, five minutes. No biggie." She smiled sweetly.

Bill trailed out of the Mystery Shack with Dipper and Mabel's suit cases floating behind. He was rather quiet but caught Pacifica's attention all the same.

"And look, there's the demon." Pacifica said disdainfully before turning to Dipper to add: "I can't believe you're actually screwing him after all the crap he pulled seven years ago."

Pacifica, along with many others, was involved with the events that almost resulted in the End of the world at Bill's hands. She had admittedly been integral to stopping him even if it was Dipper who casted the decisive spell. Though where mostly everyone else had let go of what had happened nearly a decade ago, she hadn't. She couldn't really be blamed, much to Dipper's anger. She had been rather frightened just like everyone else. For a moment, it really had seemed like the world would end.

"Pacifica!" Mabel whined, "We talked about this…" and she glanced worriedly at Bill to see if he was offended, "Bill's one of the good guys now."

"Sure." Pacifica said sarcastically.

"Is she having a go at me?" Bill grinned, slowly lowering the suit cases to the ground.

"Bill, no." Dipper warned.

"Yeah, I am." Pacifica snapped, "You should be dead! We never should have let you live!"

Mabel's mouth snapped shut with the building tension. She didn't really know what to say to alleviate it and Dipper was essentially on the same boat. He just hoped the demon wouldn't snap and teleport Pacifica to an alternate world that could kill her.

"Bill…" Dipper said as the demon hovered closer to Pacifica with a mesmerized gaze.

He stopped inches away from her and Pacifica, somehow, remained unfazed by Bill's unnerving proximity. He still had a very worrying smile plastered on his face and held Pacifica's gaze like she hadn't wished him dead to his face. The demon's smile then vanished and Dipper was sure he was going to do something bad but—

"I'm sorry." Bill said and extended his hand as an apology.

"W-what…?" Pacifica stuttered.

"I'm sorry." Bill repeated.

"Why…?" She asked.

"Because I almost screwed up really badly." The demon said and dropped his gaze to the ground, like he was being haunted by something. "I'm not sorry for what I did. I like where I am now and if I hadn't done what I did back then, there's no guarantee I would have ended up here. I'm sorry for having almost screwed all that up."

"So…" Mabel sighed, "That was really unexpected."

"You're telling me." Dipper said, "That was really grown up of you, Bill."

"Yeah, well, that Jesus guy had some smart things to say." Bill said and hovered away, "Don't be expecting this too often, though."

"Never in a million years." Dipper huffed.

They opened the back of the car and began piling their suitcases in. It was difficult to get everything to fit what with the unnecessary amount of things Pacifica insisted on bringing with them. The ruckus they made as they desperately tried to shove the bedazzled suitcases in the creaky vehicle while Pacifica yelled for them to be careful eventually brought Grunkle Stan to the porch. He rubbed his bleary eyes and yawned, confused by what was going on.

"What the hell are you kids doing up this early?" He grouched out.

"Oh right, we totally forgot to tell them!" Mabel laughed, "We're going to Newport for a week."

"Newport? Why?" Stan asked.

"The beach!" Dipper answered before slamming the trunk shut.

"Well you kids have fun." Stan said, "And make sure Cipher doesn't set anything on fire. Or terrorize anyone half to death."

"Excuse you!" Bill frowned, "I'm not a child!"

"Don't worry, we got him." Dipper said, shoving his boyfriend playfully.

He stood on the porch and watched them pile into the car, Dipper in the driver's seat with Bill just next to him and the two girls in the back. Pacifica glared at the demon suspiciously but kept her mouth shut. Stan waved them off as the vehicle roared to life and left the Mystery Shack's parking lot. This was definitely going to be an interesting vacation. Dipper and Mabel only prayed for a minimum of casualties.
