12 Early to Rise
Dipper woke up at about seven on Thursday morning. Alone. Yawning, he got up, did his morning bathroom routine, got dressed, and went downstairs wondering where Mabel was.
She sat at the dining-room table, leaning over a large bowl of brightly-colored cereal, nom-nomming away. “You got up early,” Dipper said as he poured himself a mug of coffee. “And you’ve got clothes on!”
“Yep,” she agreed, glancing down at her dark-blue sweater with a happy sun-face emblem on the front. “Panties and pants and everything! ‘Cause you and me are not gonna fool around today, and I’m going shopping. Wanna come with me?”
Dipper served himself a more moderate bowl of Krunchie Kookoo Kolors and splashed some milk in. “Where are you going?”
Mabel screwed up her mouth as if giving that question deep consideration. “Well, in the morning, to Sew Many Fabrics, ‘cause Mom made us pack light, and I didn’t bring sewing supplies and fabrics and all. It opens at nine sharp, so I'll hit it first. Next I think after that, maybe KnitWitts for yarn and knitting supplies. And Raft o’ Craft, for clay and tempera paints and some other crafty stuff. Then I’ll grab lunch somewhere, and this afternoon on the way home I’ll stop at the supermarket ‘cause we need bread, milk, and eggs, and maybe I’ll shop around for goodies—come with me if you want, it’ll be fun!”
"You have money for all that?"
"Oh, yeah. I talked to Dad, and he emailed me a certificate for a prepaid VivaCard with five hundred bucks on it. All I have to do is visit the bank with my ID and the card info, they activate the plastic for me, and I'm good to go. Anything left over's for living expenses. Want to come with me? Fabrics and crafts and groceries, sooo much fun?"
“I’ll pass,” Dipper said. “I’ve got a bunch of books on my tablet that I want to start reading. And maybe Wendy will call or text and let me know what time tomorrow she’ll show up.”
Mabel grinned at him. “Yeah, if she sends you any dirty photos, promise me you won’t jerk off, Dip. Store lots of spunk and build up your stamina! Give her a reunion to remember! Swear you'll lay off jacking off!”
“I promise,” he said. “YOU promise that you won’t come back all horny and strip naked and jump me as soon as you get back.”
“I’ll think non-sexy thoughts,” Mabel said. She washed her cup, bowl, and spoon. “We're almost out of cereal, so I'll add that to the list. I know you like plain old boring cornflakes, so I’ll buy a box of those, and for me I’m thinking of Choklit Chokers. Any other requests?”
“Pitt Cola.”
“Yeah, but we could get those from the Shack store room.”
“I’d rather pay for them than steal from Soos.”
“Okay, okay, a twelve-pack o’ Pitts.” She picked up her heavy quilted jacket and leaned over for a kiss. “Be good, Dip. I’ll be back home whenever. You okay for lunch?”
“Sure, I'll find something. Drive safely.”
“Ha! Fat chance! But I won’t take any fat chances, brobro. Bye, now!”
When she had gone and Dipper had finished breakfast, he turned on the parlor TV and turned the volume low. The morning news was on, though nothing much was new. There were places in the country where hospitals couldn’t take new patients. There had been a serious mass shooting in Texas, five people dead, eight more wounded. Some quarrels among the British royal family.
Dipper turned the sound down to a faint buzz, then checked his phone—no messages so far today—and sprawled on the sofa, opening the reader app on his tablet and starting to read Spectres and Spirits: My Forty Years of Ghost Hunting by Franz Flotzer. Years ago, Flotzer had been a celebrity ghost hunter, and Dipper had seen video clips of him from talk shows back in the 1980s and 90s. However, now that he was reading the man's book, Dipper started to suspect the guy might have been a fraud. Halfway through the first chapter, “My First Haunting,” he thought his gruncle Ford could write a book twice as interesting as this one. Plus, the haunting didn’t seem very convincing, mainly consisting of the squeaks and groans a person might hear in any old house.
Then his phone rang, and he snatched it up. “Wendy!”
“Hi, Big Dipper,” she said. “I’m packing for the drive tomorrow! You ready to see me again?”
“So ready!” he said. “Oh, my gosh, Wendy, I miss you so much. Want to go to face-time?”
“Nah, my hair’s a mess. I’ll want to tame it down before I see you.”
“Oh, okay. What, uh, what time are you expecting to be here?”
“It’s not an easy drive,” she said. “We’re way in the boonies up here. Near as I can figure it, it’ll take me between eight and nine hours to drive it. I broke the trip in half on the way up, ‘cause Dad was already here with Marcus, but I plan to drive straight through tomorrow.”
“Great!”
“Yeah, I wanted to start at six, but Dad’s insisting that I cook him and my brothers and cousin a big breakfast, so I’m guessing I’ll take off around seven a.m. Best case scenario, I’ll haul into the quarantine quarters around four p.m. Which means that I can be at our house by five or a little before. Want me to come to the Shack, or would you be comfortable spending the evening with me in the Corduroy casa?” She dropped her voice lower: “You can also stay the night. Nobody but us two there.”
“That sounds fantastic.”
“Let’s make it a date, then. What are you doin’ now?”
“Just kind of laying back on the sofa, reading a book. Mabel’s gone out shopping and plans to be gone for most of the day. I told you about Stan’s leasing us the truck.”
“Yeah, I want to take a look at it when I get there. Are you ready for me?”
“I want to take you in my arms and never let you go.”
She dropped her voice even lower, made it sexy, and he guessed that she might be in earshot of a relative, maybe even of her dad: “If you think your adventures with ghosts and monsters and all were thrilling, you ain’t seen nothing yet. Gotta run right now, but I’m so looking forward to seeing you tomorrow!”
“Same here,” Dipper said.
It took them a few more minutes of exchanged pleasantries before they hung up.
“Damn it,” Dipper muttered.
Just talking to Wendy had been enough to give him an erection. But, as Mabel had already advised, Dipper didn’t want to shoot his ammo before Wendy got there, so he grimly ignored it and tried to get interested again in the ghost book. The author’s semi-hysterical, exaggerated style proved to be an effective anti-aphrodisiac.
*
By eleven-thirty, Mabel had stowed six big bags of craft, sewing, and knitting supplies in the back seat of the pickup’s extended cab. She was just considering whether she was hungry enough to get a sandwich somewhere—nah, not yet—when her phone rang. She recognized the number and hurriedly answered: “Wen!”
“Mabes!” Wendy laughed. “Okay, just wanted to let you know I’ve cleared the health scanning and quarantine stuff. Are you at the Shack?”
“No, I’ve been out shopping.”
“Yeah, Dipper told me that earlier.”
Anxiously, Mabel asked, “Did you tell him you were arriving today instead of tomorrow?”
“Of course not! I fibbed 'cause you wanted me to. You practically swore me to silence. I’m tired, though. I got up at two this morning to make the drive! What’s up?”
“Tell you when I see you. Listen, don’t go to the Shack!”
“No, I’m heading for our house. It’ll be freezing, so I’ll have to get the heat started. Want to meet me there?”
“Yeah, but I don’t want to come by Gopher Road, ‘cause that would take me right past the Shack, and if Dipper was down at the mailbox or something, he’d recognize the truck.”
“Good thinking,” Wendy said. “Okay, let me give you a different route. Head toward the lake on Lake Drive, but then turn right when you pass the middle school, that will be on Trembley Road, right?”
“Past the middle school, then right on Trembley,” Mabel said. “Wish I had more experience driving in the valley! Then what?”
“Okay, you’re gonna drive about seven miles on Trembley. It’ll get curvy. When you cross Batton Bridge, watch for Timber Trail, it leads off to the right, but you’ll have to be sure not to miss it. It’s just a small secondary road and the sign’s hard to see if you’re not sharp. If you get to the scenic overlook on the right, pull in and turn around and go back two miles.”
“I’ll take it slow and watch for Timber Trail. Right on that.”
“Yeah, and Timber dead-ends into Gopher Road like three miles on the far side of the Shack. Turn left on Gopher, and you know where our house is.”
“Yeah, once I'm on Gopher, I’ll find it. Right, right, left. Pretty easy!”
“Okay, I’m heading thome now. Give me a little time to get the house warm and I’ll see you at . . . say about in an hour, around 12:30?”
“Gotcha! Hey, I’ll bring us a pizza!”
“Sounds great. Not a Hoo-Ha’s, though. Bernie’s? Pepperoni, mushrooms, olives?”
“And I’ll stop and get us a six-pack of beer! No, strike that. I’ll get Pitt’s for myself. I’ll tell you a story about me and alcohol. But do you want a beer?”
“Nah, you’re too young to buy it and they’d card you for sure. Pitt Cola’s fine. See you then, Mabes!”
Mabel ordered the pizza on her phone and arranged to pick it up at 12:10. Bernie’s was pretty efficient, and she drove through. Then on the way out of town she stopped at a convenience store and got a six-pack of cold Pitt’s.
She had no trouble in finding Trembley Road and slowed when she crossed the bridge, then took the winding, narrow Timber Trail. When she emerged on Gopher Road, she immediately recognized the surroundings. Wendy’s house was not far up the hill.
She parked next to Wendy’s pale-green Jeep and saw woodsmoke billowing from the chimney of the log house. The rusty, curved crosscut saw still arched over the front porch. Wendy opened the door before Mabel could knock.
“Pizza!” the redhead said. “Come on in and let’s eat! Whoa, Mabes, your bust has really filled out!”
“Yep!” Mabel said proudly. She put the pizza box and soft drinks on the table, then pulled up her sweater and threw her shoulders back. “Check ‘em out!”
Wendy whistled. “Nice!”
“Yeah, still a C-cup, but my bra size has gone from a 32 to a 36! Except I don’t own a bra that size, so I quit wearing ‘em.”
“What did you do?” Wendy asked as Mabel pulled her sweater back down.
“Oh, I’ve got my ways. Hey, if you’d like to add some to your bust, I can manage it for you. Let’s eat and then talk.”
Between them, they polished off the medium pizza. Then they sat on the sofa in front of a blazing fire and Wendy said, “Okay, 'cause you kept insisting, I managed to slip off a day way the hell early from Dad, and here I am. Plus, I didn’t let Dip know I was on the way. I called him at like eight this morning and didn’t mention I was already on the road and getting close to home. Now I’m feeling guilty, but I did what you asked me to do. What’s that all about?”
“Well, I know that you and Dipper are planning to . . . you know, make love.”
“’Bout time, too,” Wendy said. She sighed. “I had such a rotten string of shitty boyfriends in college, two in particular, and I swore off guys like nearly two years ago, and there’s no girls around who understand me, and I’m itching for some action.”
“Yeah, and I’ve been snooping in Dip’s Internet records and I know you and he've been sexting. By the way, the only porn he ever looks at features redheads with freckles! And I’ve read his journals. He writes down his erotic daydreams in code, but I figured it out pretty easy. You’re the star of his fantasies. But you know Dipper—he gets embarrassed and shy for no reason at all, practically. I just want to prep you, so you’ll know what to expect. I’ll tell you, though, once you get him started, he’s gonna be terrific.”
For a long moment Wendy’s green gaze studied Mabel. “Mabes, straight up now, have you and your brother been . . . experimenting with each other?”
“What makes you ask that?” When Wendy just smiled enigmatically, Mabel squirmed. “Uh. Yeah, you could say that,” she admitted, self-consciously blushing and grinning.
“Did you fuck Dipper?” Wendy asked. “Don't put me off, did you?”
“Yup,” Mabel said with a shrug. “He was a vee-aye—shit, we're grownups, I’ll just say it, he was a virgin. So was I, technically. But yeah, in the last week we’ve had sack time together. Sorry.”
Wendy gave her a big, wide grin. “That is so fucking hot, dude! Here I was fretting that I was gonna have to break him in, and I was kinda nervous about that. I’m glad he’s got some experience. Makes the big step easier for me to take. So you two really full-out did it?”
“I’m not supposed to tell you, though,” Mabel said. “I just thought you ought to know what he really likes and tell you about his, uh, technique, I guess? He’s gonna go nuts when you two get together, and I don’t want him to be so excited that he shoots his whole wad first off and leaves you hanging. So I want to advise you on how to take it slow with him and encourage him and all.”
“I wanna hear all about it,” Wendy said. “First, though, you said something about fixing up my boobs?”
Mabel’s grin widened. She reached inside her sweater and pulled out the grow/shrink flashlight. “This is gonna blow your mind,” she said.
They went to the bathroom, where there was a big mirror over the sink counter, for what Mabel called the treatment. Wendy took off her flannel shirt and bra. Like Mabel, she had a C-cup bust, which she confided was “Just barely a 34. Fact, a 34 bra is loose on me.”
Mabel had taken off her own sweater. “So you want ‘em like mine? Or you want to go for a 38?”
Wendy laughed. “I don’t want to be top-heavy! Let me take a good look at what you got.”
“Feel ‘em,” Mabel said, arching her back a little. “Be my guest!” On the spot she made up a little song: “Feel my chest, feel my chest, boobs and nips and all the rest! Bob ‘em round, up and down, see ‘em bouncing all around, don’t let a single moment go to waste! Come on and feel my tits, soft enough to give you fits, and if you’re lucky you can have a taste!”
Wendy couldn’t stop laughing. “Okay, I get it, Mabes! Yeah, let me pet these pretty puppies. Smooth! Soft but perky and just firm enough. And look what your nipples do when I pinch ‘em! So pert! Did you treat them, too?”
Wendy’s hands were cool and smooth and so gentle. Mabel sighed happily. “Actually, Dip helped out. But I’ve practiced with the ray and I’m good with it now. I can treat yours, too. Grow ‘em a little and size up the nips and they get so sensitive! So you want me to enlarge your boobs up to about a 36-C? It doesn’t hurt at all. Wanna go for it?”
“Yeah, I do!”
Mabel reached out to stroke Wendy’s breasts. “And maybe we can take ‘em out for a test spin?”
“Yeah, I think I’d like that,” Wendy said. “You and me started something the last time you guys were in town. We’ve got unfinished business. Hey, if we fool around will it make trouble? Does Dipper know about us?”
“I told him we’d done a little physical stuff. He doesn’t mind. I think he’d be crazy jealous if a dude told him that he’d screwed you, but he’s okay with the idea of girls making out. He even thinks it’s hot. I know, ‘cause he’s got a video collection of red-headed girls going down on each other and stuff. He’ll be intrigued if he thought you had some lesbian tendencies.”
Wendy snickered. “Matter of fact, I do! I mean, I’m not a full-time lesbian, but especially after some guy treats me shitty, I need SOME kind of release. And girls understand.”
Mabel bit her lower lip. “I think even . . . don’t quote me on this . . . that if you suggested that he and you and me might have a threesome—”
“Lets, uh, leave that for later,” Wendy said. “Maybe. Can’t say I’d jump out of the bed if you got in with Dip and me! After he and I get, you know, comfortable with each other, let’s think about that. Boob job now?”
“Yeah, boob job!” Mabel said. You stand over here, so my back’s to the mirror—don’t know what would happen if the flashlight beam reflected off it. Now put both hands on your head, with your elbows out to the side. Hold still. And . . . “
Wendy gasped as Mabel hit her right breast with a quick flash of a blue ray. “Feels so weird!”
“Puffed up like a freckly pink balloon! See what you think,” Mabel said.
Wendy hefted her right boob. “Feels good. Stand beside me.”
Mabel did, and they looked at their reflections in the mirror. Mabel hefted Wendy’s tit and then her own. “Yours is still just a little bit smaller than mine. Let me give you another real quick flash.”
“Look at us. You’re about as tall as me now!”
“Yeah, Dip’s the same height as me. We’re, what, an inch shorter than you are? I can make him taller if you want!”
“I dunno. I like him the way he is, and I’m not planning to wear these boots when I see him. I’ve got some flats. Anyway, yeah, make that tit a tad larger, and then do the other one and maybe you can do my nipples.”
Mabel carefully enlarged first Wendy’s right, and then her left breast. “Definitely fuller,” she said. “And they match, girl. Now I’ve got to be careful with your areolas and nipples. Face me and stand real still. Here we go.”
For precision aiming, Dipper had recently added an old-fashioned camera iris between the flashlight bulb and the crystal. It let the beam go wide or focus narrow, and Mabel made it about the diameter of a pencil for the delicate task of enlarging Wendy’s nipples.
“They get a deeper pink,” Mabel explained. “Nothing to worry about. Dip thinks it’s ‘cause they have more blood vessels and nerves and stuff. Okay, there’s that one . . . and the other one. If you like these, let’s go with the look. I mean, they’re pokier than mine, but I know Dipper likes to lick and suck on ‘em, so this will give him a thrill if it’s good for you.”
“These feel great,” Wendy said when the treatment was finished. She pinched her nipples. “Tingly! You were right about them being more sensitive. Whoa, look at how big they get when they’re erect!”
Mabel licked her lips. “Like ripe strawberries! I wanna taste ‘em,”
“My bed’s already made up,” Wendy suggested, taking her hand. “And it should be warm in there by now.”
“Let's go make it hot!” Mabel said with a giggle.
They ran to the bedroom, tittering like twelve-year-olds. Mabel saw that the FALLOUT SHELTER sign that Wendy had ripped off from the bunker in the woods still hung over her bed. She also grinned when she noticed that an unframed photo of Wendy and Dipper wearing each other’s hats had been thumbtacked to the wall near the head of the bed. “When was that taken?” Mabel asked as she unfastened her jeans.
“Two years back,” Wendy said, sitting on the bed to take off her boots. “The last time you guys visited for any length of time.”
“He’s taller now than that now” Mabel said, helping pull Wendy’s jeans off. “He has to shave every morning and he gets scruffy by evening. He’s even got chest hair. And I guess you’ve seen what his cock looks like.”
“Just in photos—” Wendy covered her face with both hands. “Oh, girl! Tell me you didn’t look at all those sexy pics I sent him!”
“Sure I did!” Mabel said. She gave Wendy a friendly little shove and the nude redhead lay down on the bed. “Nothing to be ashamed of. Your girl gear is super sexy, and as for Dipper, well, between us, his cock is really nice now. Don't let him know I told you this, but he gave it a little size encouragement the same way we did my boobs and yours. Speaking of which—”
Mabel lay next to Wendy, propped on one elbow, and started to lick and suckle the other girl’s nipples. “Oh, snap!” Wendy murmured, shivering. “You’re right, I’m really sensitive. Bite it a little, just your top teeth and lower lip—mm, yeah, I like that!”
Popping the nipple out of her mouth for a second, Mabel said, "Hey, even Dip likes his nipples sucked! Who'd have thought? Wen, let's see if we can do each other at the same time now."
It took a little planning, because Wendy’s bed wasn’t all that big, but finally Mabel was able to kneel down and lower her own tits so Wendy could work on them with her mouth, and at the same time she gave Wendy’s nipples lots of loving attention. After a few minutes of playing around, Mabel said, “Don’t know about you, but I’m getting wet!”
“Me, too,” Wendy murmured.
That called for Mabel to stretch out next to Wendy. She reached over and toyed with Wendy’s neat pubic patch—she’d shaved or waxed it down to a red landing strip. Wendy returned the favor, then raised up to stare. “A heart shape?” she asked.
“Yeah, my idea! You’ll never guess who shaved it into a valentine, though. Or maybe you will!”
“Not Dipper?”
“Yes, Dipper! He did a decent job, too. I tidied up later with some depilatory. Now feel how smooth.”
“Very classy,” Wendy said, rubbing the area with the tips of her fingers.
“Yeah, and you’ll be glad to know that I talked him into letting me de-hair his balls and cock,” Mabel said. “He’s still got a thick crop of pubic fuzz, but now his cleaned-up dick just glides in so easy! And if you suck it, you don’t get those horrible stray springy hairs in your—oh, are we working on each other’s pussies now?”
“I can’t resist,” Wendy said, her fingers teasing Mabel’s already slippery slit. “I haven’t had any dick OR pussy in, my God, over a year! I’m way past ready!”
Mabel looked down as she started to slip her fingers into Wendy’s warm slit. “Do you like it when I do this?”
“Yeah, you know I do,” Wendy said. “Wait, let me—there.” She had parted her thighs, giving Mabel freer access to her pussy. “That feels so good. You’re getting turned on, too, I can tell.”
“My on knob turns easier these days,” Mabel said with a chuckle. “I guess practice makes slutty!”
“Want to try a little tribbing?” Wendy asked.
“Sure! I’ll try anything with you! Uh how do you do that?”
“You’re kidding!”
“No,” Mabel said. “I think I’ve heard the word, but I’m not sure exactly what it is. It’s like with a double-ended dildo, right?”
“Not hardly. Don’t even have one of those. It’s when two girls—ah, I gotta show you. Come on, let’s go lay on the floor in front of the fireplace. We need room!”
Wendy spread a couple of quilts on the floor and then had Mabel lie down on her side. “Open your legs,” she said. “Lay on your side. Man, you got a real pretty pussy! Now I’m gonna scissor you.”
“I think I see what we’re gonna do!” Mabel said.
Wendy scissored her legs between Mabel’s and moved in, pressing her pussy against Mabel’s, like an open-mouthed kiss except no mouths were involved. “There we go,” the redhead said. “Now just sort of grind and I’ll do the same. Wow, you’re hot. And slippery! How do you like this?”
“It’s different,” Mabel said, moving to rub Wendy’s pussy with her own. “It feels great, though! I thought this was pussy play, but it's called tribbing, huh?”
“Uh-huh. I can cum doing this. You?”
“Be fun finding out! Hey, you’re cheating!”
Wendy was cuddling and stroking her own boobs, her thumbs at work on the stiffened coral-colored nipples, which throbbed for attention. “Can’t help it. If it’s not too awkward, I’m gonna want Dip to suck on my nipples while he fucks me. Sort of one my fantasies. I can go faster if you can—"
“They’re off!” Mabel said, like someone announcing a race. She shifted her position a little and pressed even harder, her clit against Wendy’s, the girls grinding hard, their hot juices flowing and merging and spilling over her thigh. “Picture me as Dipper, and pretend you got a nice thick long cock in you!”
“Oh, dude!”
“Ha, my bro was right! Wen, your face and boobs are turning red! That means you’re about to—”
“AAAHHH YEAH!” Wendy bucked like a bronco, and her excitement sent Mabel over the edge, too. They locked together, quivering, gasping for air. Then Wendy relaxed her thighs and and said, “What the hell was that? Did you SQUIRT into my pussy?”
“Yeah,” Mabel panted. “I do that when it’s really good. Dipper says it’s not all pee, its female ejaculate. A mix of a little bit of urine and a lot of the slippery pussy juice that gets you all lubed up. You can’t help when it happens, but it excites the boys. Well, one boy, anyhow, my brobro. Kinda like it’s proof you’re not faking an orgasm.”
“I love this glowing, satisfied feeling. Let’s snuggle and pet each other.”
They did, boobs to boobs, Wendy’s long left thigh between both of Mabel’s. They kissed and murmured. “So what started you squirting?” Wendy asked.
“I’m pretty sure it started strong right after Dipper enlarged my clit. It’s like a trigger, you know, and now when it’s real happy, it makes the stuff shoot out.”
“Will you do mine?”
“Love to! Where’d I put the flashlight?”
“It’s on my bed.”
Mabel stood up. “Don’t you go anywhere!”
“Dressed like this?” Wendy asked with a grin.
“Me, I love naked. BRB!”
She came back with the flashlight and focused the iris way down. Then Mabel lay on her stomach between Wendy’s spread legs.
“You’re gonna have to open way up,” she said. “Yeah, now reach down and hold your pussy open so I can see the target.”
“Guys can never find it,” Wendy complained. But she raised her butt and stretched her legs wide—she was incredibly flexible—and then with both hands she pulled on her labia. “See it?”
“Yeah, it’s real cute. It’s only about the size of a pea, though. I can make it as big as a golf ball!”
“Let’s not go overboard.”
“I’m gonna touch it to be sure it’s the right spot.”
“There’s only one to see—OOH HOO HOO, that’s it, that’s the place!”
“Try to hold still. Here we go.”
“Nngggg-God, that feels so—how big are you making it?”
Mabel chuckled. “Right now it’s about the size of s peach pit! I might be able to make it longer and give you a cock!”
“Don’t you dare!”
“I’ll shrink it down in a minute. First, though, see how this feels.”
Wendy moaned as Mabel sucked the whole thing into her mouth, held it between her lips, and polished it with her tongue.
The redhead quaked and shuddered. “Oh my god, shit yeah! I never felt like—suck it, Mabes! No, no fingers inside me—UNNNNHH!—I—I wanna see if I can cum just by you licking—FUCK YEAH! AHHH!”
A moment later, a dazed Wendy looked down. Mabel rested her chin on the other girl’s pubis, her grin wide and her face dripping. “Congrats,” she said. “You’re officially one of the Squirt Girls now!”
“I don’t think I could take that for long,” Wendy said, her breasts bobbing as she drew great, long breaths. “Not regularly.”
“I’ll size your clitty down,” Mabel said. “Make it . . . about marble-sized. That’s plenty big and sensitive enough for fun, but not so big that you’ll get addicted and start squirting everywhere you go!”
“Wow.”
The adjustment took only about five seconds. Then Wendy reached down and felt the result. Mabel asked, “You like?”
“Oh, yeah! I can’t wait until Dipper gets his fingers and tongue on it!”
Mabel put the flashlight aside. “That got me hot again. Let’s fool around a little more.” She crawled up the long length of the redhead until Wendy could kiss her. “Mm, do you like the way your juice tastes?”
“You know, I kinda do?”
“Dipper loves the taste of pussy juice, too. Now I want to tell you—and show you—just what he likes. And I want to warn you, he’s still not always sure of himself. He won’t just tell you if he wants you to, oh, try to deep-throat him. You’ll have to read the signs and guess right. Good part is, if you ask HIM to do something kinky to you, he’ll do it! I mean anything. Just tell him, he won’t get offended.”
“Like what?” Wendy asked.
“Wellll . . . I always wondered about anal. I have a vibe—his name is Forky. He’s double-headed, got this sort of recurved penis part that goes inside and against my G spot, and a curved narrower prong that fits in my butthole, but it’s too short to do much for me. So I talked Dipper into fucking my asshole.”
Wendy's eyes widened. “Never tried that,” Wendy  murmured. “Wondered about it, though. How was it?”
Mabel gave her a mild grimace. “Kind painful at first. If you do it, you need to stretch things out back there before you start and lube up real good. I think I’m gonna order me a butt plug. Ever used one?”
“No. I think Tambry used them when she started going with Robbie. I mean, I know what butt plugs are.”
“They train your back door to stay open enough so a cock doesn’t feel like it’s ripping you apart. Anyway, once Dipper got inside my cave of wonders, I told him just how to move, and he did it just right, and it was different but real sexy. Before I knew it, it didn’t hurt at all and started to feel really fuckin’ good. And I had Mr. Buzzy, he’s just a normal vibe, up in my pussy, and it was like being peed deed off—wait, that’s wrong, it’s got a pee and a dee in it though—”
“D-P’d,” Wendy suggested. “Double penetrated.”
“That’s it! And my God, it makes you feel so fuckin’ FULL! It was great.”
“Now let me get this straight, are you telling me that Dipper needs instructions for every step?”
“Not really,” Mabel said. “He won’t mind ‘em, though, and be sure to give him positive feedback. See, he’s anxious, and he’ll worry that he’s not measuring up, not pleasing you, unless you encourage him. So when he’s fingering your pussy, say, and he just misses your clit, just kind of writhe and say, ‘Little higher—little more—yeah, there!’ and he’ll do his damn best to please you. He’s kinda fumbly at first, but once he gets going, man, is he good!”
“I’m kinda nervous myself," Wendy said. “Not because of Dipper, because of me. Will I rush things too much if I just sorta take charge?”
“It probably won’t matter,” Mabel said. “I mean, he’s been crushing on you since he was twelve! Still, yeah, I see what you mean. Let him make the first moves, even if you gotta be sneaky. Like, always encourage him. If he holds your hand, move his hand up to your boob, right? And kiss him and tell him he can go further if he wants, you’re up for whatever. Will that make you lose respect for him or something?”
“No way,” Wendy said. “God, the guys I’ve been out with—so many selfish sons of bitches. I know Dipper’s kind and thoughtful, and I'm good with him being just a little, you know—”
“Awkward,” Mabel said, nodding. “And timid ‘cause he hates to think of not pleasing you. You just gotta boost his ego. And DON’T tell him you know about him and me, uh, doing the deed and all. See, I haven’t had luck with guys, either. All the ones at school and then at college at first thought I was too easy because I’m kinda goofy, and they’d push me too hard and too fast and get me mad, and I’d slug ‘em. Or they’d ask me on a date and before it happened, I’d learn they were already making fun of me. That makes me feel small. So, anyway, I figured that being up here in the Falls where stuff is weird anyhow, I might have a chance to meet a guy who wouldn’t mind it if I was a little bizarre, but I didn’t want to go into a relationship as a virgin. So me and Dipper . . . helped each other out. I’m talking too much, but I haven’t had a friend to share stuff with for a long time.”
“Uh-huh,” Wendy said, caressing Mabel’s boobs. “I get what you're telling me, Mabes. You sort of fell in love with your own brother.”
“Yeah,” Mabel whispered. She bit her lip. “And him with me. Honest, when I started it, I thought it would just be physical. Give him my virginity, let me take his, bet past that big step, done deal. I can’t help the way I feel, though. Dip and I started something I’d love to keep going—but I know he wants you. You’re not shocked?”
“Mabes,” Wendy said patiently, “I’ve lived in Gravity Falls my whole life. Nothing could seriously shock me. Hell, there are people here married to woodpeckers, for fuck’s sake! And they say there was a Northwest couple back in the nineteenth century that got married, and they were mother and son, and they had like Pacifica’s grand-dad, so HIS late grandfather was also his uncle by marriage, and his mom was also his grandmother. Twincest can’t be more mixed-up than that!”
Mabel kissed Wendy and said, “Okay, I admit I asked Dip that if you and he weren’t together twenty-four seven, could you and I play around some. He thought we’d feel guilty.”
Wendy considered that. Then she suddenly slipped off the bed and knelt, going down on Mabel.
“What are you doing?” Mabel asked.
Wendy stopped licking and gazed at her over her pussy. “Well, we didn’t get up to much the first time, but now that we’ve fucked, I think we oughta get friendlier. And it’ll give me time to think how to make it clear to him that the idea of you two having sex doesn’t bother me at all. We can share him! If I know guys, he’ll come to like that idea pretty quick.”
Mabel took a sharp breath, loving the feel of Wendy’s tongue on her clit. “You’re the coolest person I know!”
Wendy laughed low in her throat. “I know, dude. Tell me about it later.”
“After we sixty-nine?” Mabel asked hopefully.
“Mabes, you talked me into it!”
"Yay! It's one of Dip's faves, too!"
Performing mutual oral sex with Dipper was one thing, but with Wendy it was something delightfully different. Not that Mabel didn’t love the feel of Dipper’s thick, throbbing cock in her mouth, or its taste or the feeling of his tongue getting more and more expert at slurping her slit and finding her clit and driving her crazy. That was all wonderful, and she also loved when he shot his hot, thick creamy cum into her mouth. She’d grown to adore the taste—like the first time she tried shrimp, she’d first thought yuck, never again, but now it was one of her favorites.
But Wendy’s tangy, tart juices were another taste sensation, and the two girls were so in tune that when Wendy sucked in one of Mabel’s frilly pink inner labia and massaged it with tongue and lips, Mabel was instantly returning the favor. After a few minutes it was as if they had become one lusty organism, each part knowing exactly what pleased the other and each returning the stimulation exactly the same way.
This time neither yelled when they simultaneously came, they just pressed their faces closer and took the gush. When they separated, Wendy took Mabel into her arms and they just kissed and tongue-probed for a long time. “That was my best orgasm yet,” Wendy whispered. "Boy or girl, that was the top one!"
"Great for me, too,” Mabel agreed. “Oh, my God, I’m in love with my own brother and my brother’s girlfriend at the same time! I’m so fucking slutty!”
“You’re just the right amount of slutty,” Wendy said in a comforting way. “Hey, what time is it? Close to two? You wanna see something hot?”
“You mean like sexy hot?”
“Is there any other kind of hot? Yeah, girl, sexy hot!”
Mabel perked up. “Really? You mean like online porn?”
“Not . . . exactly, but close. It’s streaming live in like ten minutes. Come on and let me set up my laptop.”
“Do I need clothes?”
“Mabes, you SO don’t need clothes!”
They piled pillows and folded blankets on the bed and sat there. Wendy stretched out her long, strong legs and balanced the laptop on them. “Let me switch it on . . . and it’ll take a few seconds to boot up. Now let me input the address and my ID and PIN . . . here we are. Can you see okay?”
“MetaCumCam?” Mabel asked, seeing a big icon of a video camera. “What is that?”
“You’ll see. Ah, the countdown’s started up there in the right corner. Seven more minutes.”
“Is this gonna get me all hot and ready for more sex?” Mabel asked.
“Pretty sure it will,” Wendy said.
“Good!” Mabel reached down and idly began to play with her pussy. “Bring it on, and I’ll get ready. What is it?”
“It’s a surprise,” Wendy said. “I’ll tell you about it once it starts. It’s not two-way, so they can’t hear or see us. We can type in comments and requests, though.”
“You got me all curiousy,” Mabel said. “By the way, about sucking my brother’s dick—”
“Okay, we got a few minutes,” Wendy said, giggling. “What should I know about your brother’s dick?”
“Okay, so you remember how bad Dipper used to stink when he was younger?”
“Oh, sure,” Wendy said. “Matter of fact, little confession, his body odor was such a relief to me when I was fifteen! I mean, like all the guys I knew in school doused themselves with Axe to the point they made me want to gag. Dipper just smelled like . . . boy. Are you telling me his cock’s gonna stink and taste bad?”
“Aw, no!” Mabel said. “In high school, when Dipper started to try to pick up girls, he got obsessive about being clean. Fortunately, I snuck into his bathroom and poured out most of his cologne and replaced it with ninety per cent water. He didn’t know the difference. Anyways, now he showers in the morning and then again before bed. And his cock just tastes nice and cocky. And I love the way his sperm is hot in my mouth. It’s bland but kinda peppery—”
“Shh, the show's starting!”
Mabel turned her attention back to the screen and saw a title had appeared, made of animated, flaming letters: “HOT SLUT AND BIG STUD.”
Then the shot changed to a girl stretched out in bed, her legs wide open and a mushroom-headed vibrating wand on her pussy. “Hi,” she purred.
Mabel’s jaw dropped. “OMG! TAMBRY?”
“And Robbie,” Wendy said. “Short version—they couldn’t get band gigs after the epidemic started, and they needed money, so Tambry became a camgirl. They do a show a week, ‘bout an hour at a time, and they take requests if people buy tokens and  use ‘em to pay for specific sex acts.”
Now a red track ran across the right side of the screen, scrolling the names of fans in white letters: FKFAN13, HOTPUSS33Z, WANTSEX, DOIT4ME! and more. Many more.
Tambry, buzzing her clit, said provocatively, “Hi, guys! Me and my stud are gonna give you a hot sex show. If you’re a fan, welcome back! If you’re new, buy a few tokens and tell us what turns you on and we'll do it! Who wants me to start with a juicy blowjob? Who’ll put up a hundred tokes? If twenty of you horny viewers do that, you’re gonna see some serious sucking! When the bar turns green, that’s when the fun begins!”
“Her hair’s different,” Mabel said. “It’s all pink now!”
“Yeah, she lost the highlights and just dyed it all. And she shaved her pussy. Look at the totals! When that yellow bar hits two thousand it’ll turn green. It’s shooting up fast, that means the pledges are pouring in—there it is! And there’s Robbie!”
Robbie, or Stud, as they called him on the show, wore a whole-head black mask, a sort of hood with cut-outs for just his eyes, lips, and chin. He climbed onto the bed and Tambry started to jerk his cock.
“Ooh, he’s all scrawny!” Mabel said.
“Yeah, and his dick’s not that great. But watch how Tambry makes it look bigger than it is.”
The camera came in for close-ups as Tambry face-fucked Robbie, and by deftly handling his cock, she did make it seem as though he had more than the first impression suggested. She moved faster, letting out muffled moans, and he groaned, too.
At the crucial moment, Robbie tapped Tambry’s shoulder, and she reared back, letting him hosepipe sperm over her tits.
“She doesn’t take it in her mouth?”
“Nah,” Wendy said. “She's squeamish that way. Viewers like proof that he’s really cumming, so he shoots it on her tits, but later you'll see that Tambry does take it in her pussy and ass and then shows the camera a close-up of a cream pie. If Robbie can get it up a couple more times, it gets hot.”
“How . . . much money are they making?”
“Each token’s fifty cents. For this the fans ponied up . . . two thousand three hundred tokes, so they’re raking in $1150, gross. They have to pay the provider half of that, and they keep half. The rest of the show, the prices for things like pussy and ass fucking  go up. Usually they’re clearing about six or seven thousand bucks a week. More than they ever made as a band!”
They watched the rest of the show. Tambry fucked Robbie reverse-cowgirl style, and the camera focused on his cock pounding her. As Wendy had predicted, they got a lot more tokens for that—Tambry promised that Robbie would cum inside her and she’d show off a cream pie for ten thousand tokens, and they made that goal in about twenty minutes. Mabel suspected some trickery when the camera lost Tambry as she was dismounting. A moment later she sprawled on her back, spreadeagled in bed again, stretching her pussy open for the camera, and it was drooling pearly whitish liquid.
“That's a really big load. Wait, is it even cum?” Mabel asked.
“Good eye, Mabes,” Wendy said, reaching over to pat the younger girl's ass. “Nope! It’s a mixture of powdered sugar and cornstarch and water. Robby can’t produce that much, so Tams loads up rubber bulbs with the fake stuff and gives herself a fill-up in between poses.”
“Boo! Cheat!” Mabel said.
“Let her have this,” Wendy said. “Not her fault if Robbie has to fake an orgasm now and then, and she and him are savin' up for a down payment on a house. Okay, while they rest, the second-string couple’s up, they’re coming in from Florida. Klint and Bouncy are their handles, but nobody knows their real names. He’s starting their show by eating her out, see? You can glimpse a little of the beach and ocean through the window there. It’s later in the day ‘cause Florida’s in the Eastern time zone.”
“He’s not very good with the old tongue stuff, is he?”
“Not as good as you,” Wendy said, putting her arm around Mabel and tugging her Mabel’s nipple. They watched until the girl either came or faked it, and then the show switched back to Robbie and Tambry. Wendy said, “Now it looks like they’ll wind up with a buttfuck, and usually he can cum again doing that.”
They watched to the end, and when the show closed, Wendy said, “Not too fucking bad! I'm pretty sure Tams preloaded her ass with the fake cum again,but the fans liked it. Look at the numbers. After divvying the take, Tambry and Robbie will earn more than seven k this time.”
“That's like every week? Huh! That's a lot. Uh, so where are they?” Mabel asked. "I mean, are they here, or wherever?"
“They work out of Gravity Falls, but nobody in the valley knows the ID and PIN ‘cept for me. That way Tambry’s family don’t learn what she does for a living. Did it turn you on?”
“Um, not so much,” Mabel said. “You know what I really like? What gets me so fucking hot I can’t stand it?”
“What?”
“I talked about Dipper taking showers. We’ve been doing it together. Yesterday evening we were in the downstairs shower and I wanted him to fuck me, and so he got behind me and I put one foot on the tub edge, and Dip reached around and held my boobies and he fucked me from behind while he water poured over us, and I played with my clit, and when the big moment hit, I nearly passed out—”
“That does sound hot,” Wendy said. “I don’t have a dick, but I’ve got a shower.”
“Ready when you are!” Mabel said.
As it turned out, they were BOTH ready. After another session, Wendy said she needed a nap, and Mabel said she needed to go to the supermarket, so they kissed goodbye and Mabel left, coming back in a moment later. “Forgot—” she started.
A grinning Wendy held up her sweater, panties, and jeans. “Cold outside, so take your jacket, too,” she urged, giving Mabel’s ass a friendly pat. “Keep that pussy hot!”
