14 Wake-Up Call
Dipper woke the next morning still pressed tight against Wendy. Her soft ass cradled his stiff dick. His morning was already as heavily wooded as the hills around Gravity Falls, but before he could wake Wendy and spring into action as on such a morning he would normally have done, his phone rang. With an irritated grunt, Dipper swung out of bed, snagged his pants on the floor, dug into the pocket, and found his phone. “Hi, Mabel.”
“Code red!” her voice yelled in his ear. “Brobro, you gotta get back here to the Shack, stat! Is that right, stat? Sounds funny. I ought to look it—”
“Mabel,” Dipper said, running a hand through his rumpled hair. “Just tell me what’s wrong.”
“Waugh!” she yelled “Grunkle Ford and Grunkle Stan just called me to say they’re gonna be here at eight! They want to make plans for when Mom and Dad come up to visit! They’re gonna want to know where you are!”
“What’s up, Dip?” Wendy asked sleepily, sitting up in bed, her boobs bouncy. She noticed his hard-on and licked her lips. “I see!”
“Okay, relax,” Dipper said to Mabel. “Wendy and I will get dressed and drive—”
“Hah! I knew it, I knew it, I knew it! How is Wendy in bed? Is she good as me? Will she do you any way you ask? Does she scream when—”
“We’ll be there in a few minutes!” he said and hung up.
“We’re not gonna fuck?” Wendy asked, making a disappointed pout.
“Sorry,” Dipper said. He quickly explained to Wendy. They hopped up, showered, dressed, and got in her Jeep for the drive to the Shack. Wendy drove fast for conditions—it wasn’t raining any longer, though the winding road was wet with run-off from the showers of the day before—but she was good behind the wheel, and they arrived safely at the Shack by a few minutes past eight. The only vehicle in the lot was the leased pickup, and Wendy parked her jeep beside it. She and Dipper hurried inside.
“You just made it!” Mabel said, embracing first her brother and then Wendy. “And speaking of making it, how was it, wink, wink?"
“Everything it should be,” Wendy said. “We’ll tell you someday when you’re old enough. If the Stans aren’t here yet, we need to try and make things look normal. Let’s rustle up some breakfast, guys.”
Coffee, pancakes, and bacon were easy and quick enough. Dipper mixed up the pancake batter, Mabel put strips of bacon in the biggest skillet, and Wendy brewed the coffee. By the time it was dripping into the carafe, Dipper had spooned four nice-sized pancakes on the grill, where they were sizzling and developing bubbles.
“Seriously, Dip,” Mabel said softly, “did you treat Wendy right?”
“I think it was mutually satisfactory,” Dipper said.
Wendy put an arm around him, and they kissed. “Dipper fucks like a hero, Mabes,” she said. “And he made sure that I got all my rewards, too. No complaints!”
Mabel bunched her hands into fists. “Ooh! You saucy libertines, you! Next time you two get biz-zay, I want to watch!”
“Mabel!” Dipper said.
She punched his shoulder. “Come on, Dipdop! I could make a video of your performances and also do color commentary! We could start a blog! We'd get like forty million likes and a couple death threats from people in the Deep South! This bacon done enough?”
“Looks done,” Dipper said, taking time off from pancaking to put a few paper towels on a platter. “Let those drain and do six more.”
“Makin’ bacon!” Mabel crooned. “Oh, in memory of Waddles, I have to tell Wendy this is fakey bacon. It’s made out of turkey.”
“That’s cool,” Wendy said, taking a bottle of Sir Syrup’s Genuine Maple-Flavored Gloop from the pantry. She poured about a cupful of it into a small pan and began to heat it.
Meanwhile, Dipper took up the four pancakes, put them in the warming oven, and poured four more. “What’s the time?” he asked.
“Twenty past eight,” Mabel said. “They told me they’d be here at eight sharp, but we still got about ten minutes before they show up. You know how Ford’s so forgetful that he’s hardly ever on time.”
The elder Pines Twins still hadn't showed up when Wendy, Mabel, and Dipper settled down at the breakfast table. Mabel tried a forkful of pancakes doused with ample fake maple syrup. “Mm! Fluffy! You got a real knack, Dipdop! Mine turn out flat and gummy!”
“Bacon’s nice and crispy, too,” Wendy said. “Good going, guys!”
A few seconds later, the gift-shop door opened and Stan’s raspy voice called out, “Hey, knuckleheads! You guys up and decent?”
“In here,” Mabel called back. “We're up, but not decent! But come in, anyway!”
Ford and Stan came in by way of the gift-shop doorway and Dipper said, “Wendy got back—”
“She sure does!” Mabel said. "Hey-oh!"
Dipper ignored that: “—back home, and we invited her to breakfast. Do you want some pancakes?”
“Coffee would be nice,” Ford said. “Stanley and I already broke our fast.”
“I got it,” Wendy said, hopping up and taking a couple of MYTSERY SKATCH coffee mugs from the cabinet. They were among a gross of unsellable, misprinted souvenirs imported from Outer Slovenia. “How do you guys like it?”
“Two sugars, please,” said Ford.
“Just a glug of cream,” Stan added.
They pulled up chairs and sat. “Good to see you again, Pines brothers,” Wendy said as she poured their coffees.
“Thank you,” Ford said, studying her through his specs. “You’re looking exceptionally well, Wendy.”
“How’s Manly Dan?” Stan asked. “Still away from home?”
Wendy shrugged. “Meh, he’s up at the Washington border on a job him and my brothers can't finish before the middle of May. My brother Marcus got the crud up there and was sick for like ten days and I had to go up to take care of him, but he’s out of bed and up and about again. My dad and brothers always run me ragged cooking and cleaning until they make me want to tear my hair out, and I couldn’t wait to get back to the Falls.”
“And your viral scans were negative?” Ford asked.
“Positively negative,” Wendy said, grinning. “See, me and my other brothers and even Dad got McGucket’s vaccine, but Marc wimped out. Scared of needles.”
“Sorry to hear he got sick,” Stan said. “You tell Dan that once they finish their job and get their butts home again, they oughta stay here. There’s plenty of trees to chop down in Gravity Falls and no epidemic to worry about. Anyways, Dipper and Mabel, I talked to your mom and dad last night. Your mom wants them to come up to the Falls for a week. Won’t matter that your dad can’t go into work, everybody at his company is workin’ remote for as long as it takes. Me and Ford gotta find a restful place in town for them to stay.”
Dipper gave Wendy a quick glance. She flicked her eyes toward him. Both looked disappointed.
“Um, I don’t think Mom would want to stay in the Shack,” Dipper said.
“No way!” Mabel agreed. “She’s real sensitive and the creepy exhibits in the Shack would bother her and bug her and neither of them would be comfortable with what goes on here!” She privately gave Dipper a wink.
Ford made a face. “Yes, I understand. It’s rather isolated, built over a lumberjack graveyard, and admittedly somewhat unnerving, and my brother filled the place with all these frightening fake exhibits—”
Stan set his coffee mug down in such a hurry that a little of the contents sloshed out. “Don’t knock it, Poindexter! Those FAKES paid off the mortgage when you were gone and also gave me the moolah to buy the electronic gizmos I needed to fix your freakin’ Portal and bring you home!”
“Yes, thank you,” Ford said dryly. “As I was saying, I agree with Mabel. The Pines family would be much more comfortable in other quarters, preferably closer to downtown. I suggest the Falls Inn, on the lakeshore a few miles west of town. It’s rustic but has a great view of the waterfall and mountains, it’s comfortable, it’s convenient to the clinic, restaurants, and shops, it has top-notch wireless computer connectivity, and I’m sure that Stanley and I can arrange for reasonably inexpensive rates—”
“We’ll stay here in the Shack, though!” Mabel said. “The three, I mean, two of us! Dipper and me! That’ll save rent money, and we can watch over things for Soos and keep things clean. Tidy, anyhow. He’ll pay us, I’ll bet—”
“But we can do stuff with Mom and Dad for the week they’re visiting,” Dipper said hastily. “Take them around and show them the sights. Show them where to, uh—”
“Shop and relax and so on,” Wendy supplied. "But don't like monopolize their time, Dipper. I'm sure they'll want some US tme now that your dad's well again."
“Right, I agree with Wendy,” Dipper said. “They didn’t even take a vacation last year, and then this year they both got sick, and they deserve some time off.”
“Yeah, and we also need to let them know that after they go back home, Dip and I are gonna stay here for the rest of the summer,” Mabel added.
Stan blinked. “Really? I think that’s a teriffic idea. You sure they’ll agree to that?”
“If you’ll help persuade them” Dipper said.
“This place really needs them,” Wendy added. “Dip and Mabes know every inch of the Shack, and where everything should go, how to keep it up and clean and organized. With them living here, no vandals will break in. Sooner or later the pandemic will end, and with them on the spot, the place will be able to open the minute Soos wants it to be back in business. You know, his Abuelita’s frail these days and traveling’s hard on her, so that would be a load off Soos’s mind, too. He and his family could stay in Mexico as long as they’re safe and want to be with their family, and if he wanted us to, Mabes and Dip and I could even run the business together.”
“That is a salient point,” Ford said, nodding.
“And all kids gotta leave the nest some time,” Stan said. “Okay, Ford and me will try to help convince them. But you guys show them a good time when they’re up here. Be real mature and responsible, you know. And be on your best behavior!”
“We will be!” Mabel said.
When the gruncles had gone, Mabel, Wendy, and Dipper sat in the Shack dining room, just staring at each other. “This is gonna be a problem,” Mabel said, her elbows on the table and her chin resting on her palms. “You two will have to be all prim and proper while our parents are here.”
"I think we can do that. They know I'm a friend of you and Dipper, after all."
Mabel grinned in a lewd way. "Yeah, you probably don't realize it, but when you two are in the same room togehter, the air practically hums like a vibrator, and everything smells of pre-cum and pussy juice!"
"Does it?" Dipper asked, turning red.
"Yeah, I thought gruncle Stan was looking sort of suspicious."
"Nah," Wendy said. "We can handle it. And while your folks are here, me and Dip won't hang with them very much."
“Anyhow, we’ve got at least the next week or two to get ready,” Dipper said. “And they’ll only visit here for one week. We can tough it out, right, Wendy?”
“Yeah.”
The silence stretched out until Wendy suddenly asked, “Have you told him about us, Mabel?”
Mabel blushed. “Uh, I—no. Not in any detail, not yet.”
Wendy took a deep, long breath. “Then I’m gonna.”
Dipper glanced from Mabel to Wendy and back. “Oh, don’t tell me that you two have, uh, been, you know, have been together. I meen you've actually—”
"Fucked," Mabel said. "Ate each other out. Made each other cum. God, let's just put it on the table! We don't need to use euphoniums!"
"Euphemisms," Dipper corrected automatically.
"Whatever! Wen and I have had sex, Dipper!"
“All—all the way?” Dipper asked.
Wendy nodded. “Mabes and I have gone as far as two girls could go.”
Dipper swallowed. “How long ago did you, uh—?”
“Not long,” Wendy whispered. “I sort of lied, man. I got home day before yesterday, not yesterday, and Mabel and I got together.”
“We sure did,” Mabel said. “Dipper? You’re not mad, are you? Are you okay with what Wen and I have been up to? Look, it’s totally my fault, so don’t—”
“I guess we’d better confess, too,” he said. He swallowed hard and took his girlfriend’s hand. “Wendy, Mabel and I have been, um, you know—”
“Been together," Mabel said in a mocking voice. “Let’s not sugar-coat anything here. Wendy, Dip and I have been fucking. A lot”
“Yeah,” Dipper said. “Mabel and I kind of—de-virginized each other. I know that’s creepy as hell—"
“No,” Wendy said, exhaling as her smile changed to a wide grin. “That’s kinda hot, actually. Not a dealbreaker.”
"I'm cool with fucking both him and you, Wen. Anytime, anywhere, any way. Both together! Mabel wriggled a litttle. “In fact, I’m feeling all tense right this very minute. It might be PMS, but I could use some relief before the red tide hits. How about we all three—”
Dipper looked at Wendy. “What do you say?”
Wendy thought about that for a moment. Then she grinned. “I say, bolt those doors and let’s strip!”
“Yay!” Mabel jumped up from her chair and did an air-punching victory dance. “Hey, you guys, let’s take this upstairs and put it to bed!”
Up in the attic, the three hesitated, the girls not able to look at each other without giggling. Then Wendy said, “If we’re gonna do it, let’s do it. Let’s start by giving Dip a little show.”
She and Mabel kissed each other lasciviously. Then Mabel glanced at her brother, who was unzipping his fly. “Nuh-uh, Dip! You sit on the bed. Keep your dick in your pants. Wen and I will ding your dong soon enough! No, you keep your clothes on for the time being. You just watch us. And no touching yourself!”
She turned on the laptop, went to an online music service, and picked out a slow-dance playlist. Then she and Wendy faced each other and started to do a sinuous, teasing dance. Mabel slowly unbuttoned Wendy’s shirt. Wendy pulled Mabel’s sweater off over her head. Mabel pushed Wendy’s shirt off and it fell to the floor. Now both were topless. They took turns licking and suckling each other’s tits.
Dipper leaned back, fascinated.
Then Wendy turned toward Dipper, doing a lazy side-to-side dance step while Mabel stood behind her and reached around to massage the redhead’s boobs. Wendy reached down and popped open her jeans and unzipped them. She kicked off her shoes.
Mabel came around front, and Wendy unfastened Mabel’s jeans. Facing each other, they pushed each other’s garments down and stepped out of them. Now both girls wore only bikini panties.
“Look at Dip,” Wendy said, leering at him and the taut crotch of his cargo pants. “I think this is making his ego a lot bigger!”
“Harder, too! Wanna get in on this?” Mabel asked her brother.
He squirmed. His erection had indeed tightened his pants and there was no mistaking the bulge. He was feeling hot and sweaty. “Oh, yeah.”
The two girls swayed over. Wendy took off his shirt and tee-shirt. Mabel removed his shoes and had him stand up before she pushed his pants down and had him step out of them. Now he wore only socks and his briefs, and the fly of his underwear tented out by some inches. “Let us take care of that,” Wendy said.
Mabel knelt on his left, Wendy on his right. “Socks first!” Mabel said, pulling of his left sock. Wendy got the right one.
“Ready for the reveal?” Wendy asked.
Let’s go!” Mabel said.
Each girl took the waistband of his briefs between her teeth, and then they wriggled downward, pulling off his shorts, freeing his twitching erection.
Wendy took off her panties and Mabel removed hers. “Here’s how we do it,” Wendy said huskily, reaching down to stroke Dipper's cock. “Dip, you’re gonna take me doggy style. Mabel’s gonna lay back on the bed, and while you fuck me from behind, I’m gonna eat her out.”
“And it’s gonna end happily for everybody!” Mabel promised.
Wendy patted Mabel’s ass. “But first we gotta both get lubed up so the ride’s nice and slippery. So Dip, you just watch us for a while. And if your dick gets so hard you can’t stand it, then just tap us and we’ll get into position for the grand finale.”
Dipper quickly saw that by lubing up, Wendy meant a lewd girl-on-girl 69. She straddled Mabel, who stretched out on her back and spread her knees, and both girls started to lick and suck. Their murmurings, moans, lip-smacks, and musky aromas made Dipper dizzy with lust. Mabel came up for air after a few minutes, glanced at him, and said, “Wen, you’d better take his cock in your pussy before he explodes!”
“Mm,” Wendy said. “You lay back and I’ll finish you off while we do it!”
Mabel did, crossways on the beds, and Wendy leaned way over and spread her fingers on her own butt cheeks, pulling them apart and revealing her glistening pink pussy invitingly. “Put it in, Dipper!” she said. “Don’t hold back, I can take it!”
Dipper stood behind her and slipped his stiff dick into her hot, tight, slippery depths. “Aw, yeahhh!” the redhead said as he pressed forward, wriggling her shapely ass and pushing backward to take him in even deeper. “So full! Now fuck me hard while I eat Mabel’s tasty pussy!”
Gripping Wendy’s upper thighs, Dipper began to pound her, loving the springy flexing of her butt as he smacked against it. He saw Mabel open her legs as wide as she could, the heart shape now grown in above her slit, and Wendy, holding her long red hair back with one hand, began to lick and slurp enthusiastically.
Mabel’s face grew tense with pleasure, and she started to move her hips, while she clasped her tits and played with her nipples. Over Wendy’s shoulder, back, and ass, Mabel grinned at Dipper. “Faster, brobro! I can tell she’s lovin’ this! Is Wendy a good fuck?”
“Oh, yeah!” Dipper gasped, fighting hard not to cum too quick. Wendy squeezed him in a gesture of appreciation.
Mabel put one hand on the back of Wendy’s head and in a coy voice asked, “Is she better than me?”
He gasped, “Let’s decide that later!”
Wendy interrupted her tongue-lashing of Mabel’s slit to giggle over that. “Oh, you are so gonna pay, man!”
“Back to work, girlfriend!” Mabel said , pushing Wendy’s face tighter against her pussy.
Wendy must have attacked Mabel’s clit just then, and the result was like magic. Mabel threw her head back, her chin glistening with Wendy’s juices, her teeth clenched in an orgasmic grin, and gave a high-pitched howl of ecstasy.
Dipper, drunk on lust as he fucked his girlfriend and watched his twin sister’s breasts grow first sharp and then blunt tipped as her spasm approached and her nipples and areolas puffed deep pink, knew he couldn’t last long now. And then Wendy shuddered in rippling orgasm, Mabel thrashed on the bed, and screamed, “Yesssss!”
At the same moment Dipper’s dick spurted a hot gush as he thrust as deep into Wendy as he could.
Wendy yelped, gasped, and yelled, “He’s shooting it into me, Mabes! He’s pumpin’ it in, so hot!”
Mabel sat up and patted the bed. “Let me eat your pussy! Don’t waste the cum!”
Wendy again gave directions. She lay on her back on the bed, Dipper stood beside the head, she turned her face to him and sucked and cleaned his dick with a luxurious, slow post-cumming blowjob, and Mabel eagerly sucked and swallowed cum from Wendy’s overflowing pussy.
And that was just the beginning. Later in the morning, for the next turn, they traded places, Dipper fucking Mabel while Wendy face-sat her, grinning at Dipper’s enthusiastic efforts.
When they had all cum again, Mabel hugged Wendy. “I’m so glad you’re our girlfriend!” she said.
Wendy caressed the younger girl’s boobs. “I’ve dated girls and boys both, but I never dreamed I’d ever date twins. Best of both worlds! That is so seriously fuckin’ hot, dudes!”
They spent some deliriously sexy hours and a long, energetic, ecstatic night. Then a day or so later, Mabel’s PMS and then her period put her out of the game, but she watched Wendy and Dipper’s couplings, and she did mouth duty now and then, finishing off both her brother and the sexy redhead as needed when Wendy and Dipper fucked.
By the next weekend, Mabel was back to normal, and she, Wendy, and Dipper had sworn they’d always be together. When Dan phoned to check up, Wendy told him she had a job in town that came with a room and board. Dan bought the story, so that was off her mind for a while.
When Dipper and Mabel’s parents showed up the following Sunday afternoon, Dipper announced he and Wendy were engaged and they would be staying here because, he sort-of lied, he’d taken a job as Shack caretaker until Soos could return after the pandemic ended. “Well,” their dad said, “it does look like we’re all in for a long haul. And I don’t think you’d be able to get a job anywhere outside of Gravity Falls. Welcome to the Pines family, Wendy!”
Mom agreed after Dipper promised to text them at least three times a week and call at least once every weekend.
And she didn’t even put up an argument when Mabel said, “I’m staying too. These two might get into trouble without a chaperone like me!”
With those arrangements made, twins put in an international call to Mexico City, where Soos, who was fretting about Abuelita’s health, cheerfully agreed that he’d be happy to have Dipper and Mabel working for him. “You two can live right there in the Shack as long as you agree to take care of it!”
“We’ll work just for room and board and a small allowance for food and necessities. Just give us a heads-up before you come back,” Dipper said.
Mabel added, “If Wendy will help us when it’s safe for tourists to come again, we can even open and run the Shack on our own for a while. You and Melody and Abuelita just stay right where you are at least until next fall!”
“Really? That'd be, like, wow, dawgs. Sure thing, Hambone!”
Soos gladly told Mr. Pines that the twins had a job and a home, and though Mom tut-tutted a little, she liked Wendy a lot. She agreed to the plans.
Wendy, Dipper, and Mabel walked on eggshells for the week that Mr. and Mrs. Pines stayed. Now and then Mabel would take them somewhere to shop or see the sights while Wendy and Dipper entertained each other, and the next day Dipper would show them around while Mabel and Wendy made out. At the end of their visit, Wendy even treated them to a special lumberjack picnic at a scenic spot miles out of town while Dipper ploughed Mabel right out on the Shack lawn.
After Mr. and Mrs. Pines had gone home, Wendy and Dipper had a long phone call with her father. Surprisingly, Manly Dan accepted the fact that his Wendy was engaged, and he couldn’t seriously object to her living with Dipper. That was because Wendy privately told Dan that she happened to know that Dan had not married her mother until the month after she was born, and he didn’t want her brothers to know that. “They call this blackmail!” he growled.
Wendy laughed. “Yep.”
For a moment Manly Dan hovered on the edge of scolding her, but under his toughness he was a loving dad, and seeing Wendy so obviously happy about the arrangement, he couldn’t keep up a pretense of being angry. “Okay,” he rumbled. “You got yourself a deal. But when you have your first son, you gotta name him Dan!”
Dipper agreed. After all, no son would come along for—who knew how long?
In time summer arrived. College was over. Tourists weren't coming. The pandemic kept everything int he valley cut off from the outside world and cozy for the inhabitants. The threesome settled in happily, greedy for each other’s bodies and always satisfied after their sessions. Dipper got used to an always-nude Wendy and Mabel, and he was happy to be on call whenever one, or both, called out, "Need a dick here!"
What a summer.
Now that summer, THAT summer—well, Dipper and Mabel’s first summer in town had been packed with monsters and spooks and adventures. The best summer ever!
But THAT summer of full-tilt, uninhibited, wild, unrestricted twosome and threesome sex—
Well, THAT summer was ten times as good.
