Double's Dating

"Hey Dipper," Wendy said, greeting him with a smile on her face and her flannel shirt looking a bit tighter than it usually did.

"Hey Wendy," Dipper said, feeling hot under the collar and barely stopping his voice from cracking.

"Wanna blow off work and grab a soda? My treat."

"Yes," Dipper said instantly, "Yes I would."

Wendy grabbed his hand and pulled him out the door just as Soos entered, catching sight of them leaving.

"Looks like I've got the counter then," he said with a shrug, always happy to run the register.

Half an hour later

"Sorry I'm late," Wendy said as she entered, "I didn't feel like coming in."

Stan just rolled his eyes. "It's coming out of your paycheck," he threatened as he left, not that either of them took it seriously as he always threatened to cut her pay but never carried it out.

"But you were here," Soos said. "You and Dipper left just as we opened."

"I did?" Wendy asked. "Wasn't me, I just got here."

"Do you have a twin?" Mabel asked excitedly. "You've got a secret twin you've been hiding from us! What's her name?! Is it Wendy too?! I bet it's Wendy! Are you the secret twin?!"

"What? No," Wendy said. "Soos was probably just seeing things. I haven't been early in like... ever."

"Pretty sure it was you, dude," Soos disagreed. "Flannel, Jeans, red hair, excited Dipper following you like a puppy."

"That does sound like you," Mabel said. "Wanna check the cameras?"

"Do they actually work?" Wendy asked, surprised. "I thought Stan would avoid anything that could be labeled as evidence for the prosecution."

"I fixed them," Soos offered. "Of course, all the footage over a week old somehow gets erased, but we're good for today at least."

"Maybe you got a hold of a time machine and came back in time for some reason," Mabel offered. "Pretty sure we've got some footage of an older version of me and Dipper on some of the cameras."

"Only if they're less than a week old," Soos reminded them.

"Meh, my older self can make copies if I want them," Mabel said, waving for Wendy to follow her into Gruncle Stan's office.

Wendy entered Stan's office, finding the hyperactive twin had already rewound the camera and was playing out a scene that made her jaw drop. "Dude! That's me, but with a lot more curves and is she drooling over Dipper?!"

"I knew it!" Mabel exclaimed. "Your older self came back in time to... with Dipper!" She stared at Wendy wide eyed.

"Dude!" Wendy said, waving her hands. "No! He's a bit too young for me right now, much less an older me!"

Mabel rewound the tape. "Back and to the left," she said as she stopped it on Wendy's face as she looked at Dipper. "Bingo! The camera doesn't lie. You are totally into my Bro-Bro."

"How?! Why?! What?!" Wendy sputtered out.

"No idea, let's go find out!" Mabel said with a shrug. "Shouldn't be too hard to find you two, Gravity Falls isn't exactly New York."

"Yeah, let's go find out what's going on," Wendy said. "Maybe I have an identical cousin or something."

"That sounds like a bad sitcom plot," Mabel said.

"She's not completely identical," Wendy pointed out. "She's got like half a cup size on me... everywhere."

"Time traveler seems more likely," Mabel said, making a copy of the tape to add to her Best of Summer Vacation video collage. "Now, let's go find out!"

"You know, you'd think it'd be easier to find a hot tub around here," Wendy complained as she ate her snowcone, holding Dipper's free hand with her own.

"I know," Dipper agreed, a wide smile on his face that would have taken some serious effort to remove since he was on an actual date with Wendy Flippin' Corduroy! "We could find some place to go swimming," he suggested.

"I could go for some skinny dipping," the red head agreed with a wide smile.

"R-Really?" Dipper stuttered out.

"That's what I was planning with the hot tub," she teased. "After all, neither of us have swimsuits with us."

"Yeah, we don't," Dipper realized, absently taking another bite of his snowcone.

"Know of any place where we could take a dip... alone?"

"I can think of a place," Dipper said slowly. 'This must be a dream,' he decided as he relaxed, a bit disappointed, but fully willing to see how far this dream could go.

"Anything?" Wendy asked as Mabel rejoined her. "Cause I got nada."

"Guy running the snowcone stand saw them a little while ago acting all lovey dovey," Mabel reported, pausing to take a lick of her snowcone. "They were searching for a hot tub."

"A hot tub?" Wendy hissed out. "We've got to stop them!"

"Why?" Mabel asked, leaning forward, eager to find out if her favorite lumberjane actually had a thing for her brother or not, because truthfully with the way the girl acted sometimes it could go either way.

"Because... because we still don't know what's going on," Wendy said. "I mean, we've got a girl impersonating me luring off Dipper for god only knows what reason. He could be in trouble!"

Mabel frowned and tossed her snowcone in the trash. "You're right! He spotted them heading into the woods just down the street and since the only working hot tub I know of is at Pacifica's place in the other direction, they've probably decided to go for a swim."

"The swimming hole I showed you guys?" Wendy guessed.

"Bingo," Mabel said. "While not as good as a hot tub, it's got water and privacy for whatever she has planned."

"Let's go!"

The pair pushed through the bushes and into the clearing next to a bend in the creek that Wendy had shown the twins, revealing a large pool of water just perfect for swimming and horsing around.

"Ready to get rid of all these confining clothes?" Wendy teased Dipper, starting to unbutton her shirt.

"One hundred percent," Dipper said, blessing his vivid imagination as he grabbed the hem of his shirt and pulled it over his head. By the time he'd gotten his shirt off, Wendy had gotten rid of all her clothes, revealing she was a natural redhead and was surprisingly bushy down there. He didn't stop to question it, kicking off his shoes and dropping his pants before deciding that since it was a dream, he could afford to show off a little and did a complete backflip while pulling off his underwear.

"Damn it!" Wendy cursed and Dipper turned and saw his twin sister and another Wendy?

'This is one strange sex dream', he decided, unsure why Mabel was there, though two Wendys was definitely an improvement.

"That's not Wendy!" Mabel declared, while the Wendy with her just stared.

"Look at me," the naked Wendy told Dipper and did a slow turn, "I'm the Wendy that is completely down for whatever you want."

Dipper turned to Mabel and the clothed Wendy who was still staring slack jawed. "She makes a compelling point."

"Dang it Dipper," Mabel cursed with a groan, "don't make me be the mature one in this situation, I'm allergic!"

Dipper burst out laughing.

"Dude, pretty sure that's not me," the clothed Wendy said firmly.

The naked Wendy sighed as the two approached the pair.

"Her clothes dissolved just as you pulled your shirt off," Mabel said, "pretty sure that's not a talent Wendy has. Do you?"

"No, I take my panties off one leg at a time when I bother with them," the clothed Wendy said firmly. As everyone stared at her, she sighed. "You know what I mean."

Dipper looked at the ground and saw only his clothes were present. He frowned. "It could just be a sign that I'm dreaming."

"Pinch yourself," Mabel ordered.

Dipper did and winced. "I'm really awake? This isn't just a really good dream?"

"You two are complete cock blocks," the naked Wendy said before darting forward, her right hand slipping into Mabel's clothes to snatch something. "Pocket glitter!" she called out as she threw out her hand.

"Ack!" the three cried out and swiped at their eyes, completely blinded by glitter.

"I'll get you next time Dipper," the other Wendy said as she vanished into the trees. "We will be having sex!"

"What the hell just happened?" Dipper asked as he blinked glitter out of his eyes.

"We rescued you from a fake me..." Wendy's voice trailed off as she used a handkerchief to wipe her eyes.

"So there's a duplicate of you who wants to sex me up," Dipper said in confusion, beginning to get embarrassed as he realized he was standing naked in front of his crush, flashing her and his sister. He quickly scrambled to get dressed.

"Apparently," Wendy said with a shrug.

"I was thinking she was an older Wendy who came back in time, but that wouldn't explain the dissolving clothes," Mabel admitted, easily blinking away the glitter.

"This has been the weirdest day," Dipper complained, having to adjust himself as Little Dipper still held out hope that sex would be occurring and refused to go down.

"And it's not even nine," Mabel said. "So... what do you think it was?"

"Succubus," Wendy offered. "I mean, she was me but with the sex appeal turned up to eleven."

"She wasn't that different," Dipper disagreed, making Wendy blush and look away, "but I doubt she was a succubus. They don't do running water and read people's minds for the perfect partner."

"So Wendy isn't the perfect partner?" Mabel asked, surprised.

"It's not that!" Dipper quickly exclaimed. "I mean every detail would have been perfect and she had a massive bush, which isn't something I've really put much thought into but isn't something I'm looking for... you know?"

"That is strange," Wendy admitted. "I mean I don't wax or anything, but I keep it trim enough not to get caught in my zipper. This is a weird conversation."

"Am I going to have to worry about zippers when I get older?" Mabel asked, wide eyed.

"Only when not wearing panties or if they're like thongs or something," Wendy said. "So, not a succubus I guess."

"Not sure what she is, but not particularly violent at least," Dipper said, wondering if there was something in the journals that would say what she was.

Wendy pinched herself and winced, drawing the twins' attention. "Just making sure I wasn't dreaming," she explained. "So... how in the world did you do a back-flip while taking off your underwear? I mean... that was all kinds of acrobatic."

Dipper shrugged. "I thought I was dreaming. It was surprisingly easy."

"Hold on while I pinch myself," Mabel said and winced. "Yeah, still awake."

"Why?" Dipper asked.

"Don't know, just felt like the thing to do," Mabel said. "Now... why are you so big down there? Did you go through a major growth spurt and I didn't notice?"

Wendy turned to stare at her.

"We share a room," Mabel reminded her. "I've seen Little Dipper more times than you've probably looked at the night sky and seen the Big Dipper."

"That's reasonable," Wendy agreed.

"I found a fortune teller machine and wished to be big," he joked, getting a laugh as the three headed back to the Mystery Shack.

"Better than Tom Hank's wish," Wendy said. "He kinda got screwed in that movie."

"No, seriously," Mabel said, "I want to know!"

"I heard people grow to look like their pets and found out that Dad bought me a horse last week," he replied sarcastically, getting more laughter from the two.

"Dipper!" Mabel complained.

"Would you believe I bought something I got an email about?" he asked with a grin.

The shapeshifter slithered through the forest in the form of a python. "It almost worked," she told herself, "I'll just have to plan better next time. I can slip in disguised as Mabel when she goes to a slumber party at her friend's house. Since they sleep together in the same room, no one will know to interfere."

The shapeshifter nodded to herself. "I'll pretend I had a nightmare and climb into bed with him... it's the perfect plan!"

AN: What would you have used the size changing crystal for when you were just entering your teens?

TN: I'm pretty sure that time travel does indeed explain the dissolving clothes, as time travel alone grants you access to future tech, and that would absolutely be something someone would invent for sex purposes.

TN2: If it was a smart succubus, it would have read from his mind that he knew the traits of a succubus, and would have added the bush to throw him off as an innocuous addition that would set his paranoia at ease.
