1 Morning Would
It was tough on the Pines twins, being alone in their house while their dad was in the hospital and their mom was spending most nights there with him. They had nothing to do, either, not even with their friends or in Dipper’s case casual acquaintances, because about seven months earlier the pandemic had closed the colleges and universities in the town. As a result of whizzing through the online college lessons at the speed of light, and having more time than normal on his hands, Dipper jacked off more than usual.
For spring term, Mabel, who was smart but lazy, was taking only two college classes online—two against Dipper’s four. And half the time she asked him to help her with the math assignments. Still, with just two courses and her brother’s help, she’d have the semester’s work done by May, though compared to Dipper, she was behind. Oh, well, she had until May 15 to finish all work.
They had been hoping to go up to Gravity Falls during spring break in April, but the stubborn pandemic promised to make that impossible. On the next to last day in March, their dad got sick and wound up in the hospital for a whole week. It was scary at first, but he responded to treatment and started to get better. One morning when their mother told the twins at breakfast that their dad would probably get to come home the next day, she warned, “When I get him home, he’s going to be isolated in the guest room. I don’t want you two going anywhere around him for at least two weeks, until we’re sure he’s completely over this.”
“What about you?” Mabel complained.
"I'll be all right. We're all vaccinated, and I had that very mild case the first week in February, so I'm probably doubly immune."
"But yours only lasted about three days, and you didn’t even go to the hospital,” Mabel pointed out. “Just coughed a lot and had some fever, aches and pains. And Dip and I were okay then.”
“If you’ll remember, while I was ill your father made you stay in the upstairs rooms.”
Mabel chuckled. “Dad even brought our meals and left them outside our rooms. He’s a rotten cook. Anyway, my point is that Dipper and I didn’t get sick then.”
“We’re going to do this the same way. You two will be confined to your bedrooms 24-7 for two full weeks after your dad gets back,” she said firmly. “Now clean up after you have breakfast, tidy up your bedrooms, and make up your beds! Be sure to change the sheets. Your lunches are in the fridge, and I’ll pick up something for dinner on my way home. Don’t look for me tonight until about seven. I’ll call if it looks like I’ll be any later than that.”
"Say hi to Dad for us," Dipper told her as she gathered her purse, mask, coat, and keys and headed out for the hospital.
Mabel, still grumpy, scarfed through her breakfast in about fifteen seconds, took the glass and cereal bowl to the sink, and washed, or at least rinsed, everything. She left the spoon, bowl, OJ glass, and dinnerware on the drainer. “I’ll make up your bed for you if you want,” she said on her way to the stairs.
A surprised Dipper said, “Sure, thanks.” He finished his own cereal, juice, and toast. Unlike Mabel, he actually chewed before he swallowed. Then he washed and rinsed all the dishes, his and hers both, properly in the sink with hot water and a squirt of dishwashing liquid and, being a good brother, he dried everything and put it all back in the drawer and cabinets.
Up in his room, he rolled his eyes. Mabel had made up his bed, but upside-down. The old sheets lay crumpled in a heap beside the door, the fresh sheets probably were on the bed, beneath the blanket, but the pillow was at the foot, not the head. “What the heck, Mabel?” he yelled.
From the hallway, Mabel yelled back: “Opposite Day, brobro! Because just for fun!”
He closed the door and lay down on the bed. Stupid idea, opposite day. On the other hand, with his head down at this end he could see the window in the wall beside his feet now. Looked like a bright day, nice blue sky, probably cool but already warming up. Too bad their overprotective mother wouldn’t let them go outside, even into the back yard, even wearing masks.
Feeling lonely, Dipper took his phone from his pocket, then unfastened his belt and pushed his jeans and underwear down past his knees. He texted Wendy, up in Gravity Falls: “Hi, Wen. Thinking of you. You feeling sexy?”
He waited for over a full minute, and Wendy did not reply. That meant she was busy or away from her phone. “Damn it,” he grumbled.
He switched to the photo app and flicked through the stored photos in the folder he’d labeled TECH INSTRUCTION MANUALS. No snooper would ever look in that one. Heh!
Dipper had labeled the files: WC1-WC101, then a smaller run, WN1-WN23.
The first set was Wendy Clothed. The smaller second was Wendy Nude.
She was now twenty, going on twenty-one, and still unattached. He was eighteen and would be nineteen the next August. They’d started mildly sexting the September before, prior to the pandemic outbreak. At first it was tame stuff:
***
W: Sup, man? U still growing longer?
D: Do you mean taller?
W: Do I? (winky face)
***
Over the next weeks, the texts started getting flirty. And slowly they became bolder and saucier. By mid-October, they were like this:
***
D: Oh Wen, I’d like just to touch your boobs once.
W: U can’t from way off in CA, dude. Maybe this summer. Get your hopes up. And other things!
***
A few days later, they became more explicit:
***
W: Missing you, man. When U C me again, wd U kiss my neck?
D: Sure, love that.
W: And if I unbutton, would you kiss the top of my boob?
D: I dream of that
W: And if I’m not wearing my bra, wd U take my nipple in ur mouth n suck real hard?
D: You’re making me xcited!
W: Got a boner?
D: Ys
W: Show me!
***
Which led to their first exchange of naughty photos. Dipper took his first dick pic (before he did, he augmented things about ten per cent with the growth-shrink ray).
She reacted at once:
***
W: NICE! Want 2 C that in person!
D: Cd I C ur boobs?
W: Let me think about that.
***
She did for about twenty seconds, and then she texted him a selfie, just her bare chest. He could see she was in her room because part of the fallout shelter sign showed over her shoulder. She was sitting on her bed, her flannel shirt open and no bra underneath, so the green plaid fabric formed her bare bust. Freckles sprinkled the tops of her breasts. She wasn’t all that big, but her boobs had a great shape, and the nipples were deep pink and looked very stiff. He wished he could see her face, but only her neck and the tip of her chin showed. He imagined she was smiling in a sexy way.
Then the fall virus wave hit all of a sudden, and within a week everybody was sick and everything was closing, schools and concerts and sports events, everything where crowds might be. Dipper's only relief was that Wendy and he kept exchanging stimulating texts and pics.
Over the late fall and into the winter, things had gone much further. For the past month, their pic exchanges had become much more explicit, the photos extremely revealing. Dipper kept them all, stashed in special folders to avoid suspicion and Mabel.
Dipper chose the photo labeled WN-20, one of his very favorites. Wendy was laying on her back in her bed, wearing only his pine-tree baseball cap. She had put a pillow beneath her hips and sprawled with her legs spread and her knees bent, her right hand down and two fingers holding her pink pussy open, her left hand caressing her boobs.
Her trimmed red pubic patch impishly curled in the upside-down V between her parted fingers. She obviously had taken care to prop her phone up on the TV stand and had set it for a delay before jumping into bed and posing. She was smiling, with bedroom eyes, and her pink tongue licked her lips.
Dipper blew the photo up until he could slowly scroll from pink tongue down across pink nipples and finally down to pink wet pussy. He took his time savoring the image, completely wrapped up in it.
The photo did its magic. Dipper took a deep breath and started to stroke his swelling penis. He didn’t do it frantically, but slowly and lightly. He wanted this to last as long as possible. He ached to see Wendy in the flesh and maybe explore some possibilities.
But now, damn it! With the damn pandemic going on, he had the terrible feeling that he and Mabel might miss their annual trip to Gravity Falls, and just when Wendy was giving out strong signals that this was going to be the year! Oh, that lewd smile of hers, that promising pink tongue!
“Ummnnn,” Dipper groaned softly. “Wendy, suck it for me.”
He closed his eyes and arched his back.
Then he yelped. Someone else was touching his dick.
“Just me, brobro,” Mabel said. She was leaning over the foot of his bed, and she pressed her cheek against his. “Great photo of Wendy. Why is this getting all soft?”
“Mabel!” he yelled, trying to slap her hand away. “Stop it! We’re brother and sister!”
“Sure we are,” she said, letting go of his cock. “Move over.” Mabel came around to the side and hopped into bed. She was wearing her blue culottes and a red tee shirt. Over those she wore tight pink bikini panties and a matching bra. When he did a double take at the underwear turned outerwear, Mabel giggled. “Opposite day!” she told him brightly.
When he reached to tug up his jeans, she put her foot down into the pants crotch to block him. “Nuh-uh. Come on, brobro, it’s no big deal. I’ve seen you in the nude lots of times, and I know you jack off every day. I got some great news for you but first I want you to let me give you a hand. If you know what I mean, you scallywag!”
“Mabel, I don’t have anything to cover me and—“
“Here,” she said. She took off and dropped the bra and panties before pulling her shirt up over her head, her petite but round breasts bobbing out. She hopped up for an instant, hooked her fingers in the waistband of her culottes and shoved them down. She had been going commando. Undercover commando, anyhow. He got a flash of her pubic hair, strangely geometric.
Then she climbed back into bed. “Want me to take off the socks, too? No? Okay, now we’re nearly even. Listen to me—take off your tee shirt, kick off the pants, and let’s be nakedly honest about this. Take it off or I’ll tickle you!”
Tickling was his Achilles heel. He gave up finally. Although his erection had completely wilted, he lay there on his back, naked, with Mabel lying right next to him, also naked, and he tried not to look at her boobs or—further down. “Satisfied?” he asked.
She giggled. “Not yet, but I've got high hopes! Listen, Broseph, we both have a serious sex problem.”
He glanced at her grin, very white and fetching now that the orthodontist had removed her braces. “What? What kind of problem with sex?”
“The kind as in not getting any. Let me tell you about my love life.”
He put both hands over his face. “Noooo.”
She laid her cheek on his shoulder. Then gently and softly, she said, “It’s just a short story, Dip. I’ve never gone all the way.”
“Neither have I!”
“Yeah, have you ever even had your hands on naked boobs? No? Didn't think so! Then I don’t suppose you’ve sucked on any girl’s nipples? Or put a finger up a wet pussy? Or butthole? Or eaten up a girl?”
“No, no, no,” Dipper said again, through his hands. “Wait, what? You mean eaten OUT a girl?”
“Is that when you lick her pussy—”
“Yes!”
“Well, nobody’s done any of those to me, either! And I’m sick of it. Every time there’s a guy I want to, you know, do me, it turns out he’s gay or he’s taken, or he just doesn’t like me that way for some crazy reason. I’m a vee-aye-arr-gee-aye-in!”
“You don’t have to spell it out,” Dipper said. “I know what a virgin is.”
“Listen, listen.” She reached out and gently touched his soft penis with the tips of her fingers. “Don’t think it’s weird. Just hear me out. This should cheer you up, anyhow. I happen to know we’re going up to Gravity Falls tomorrow, and we’re gonna get to stay there at least until May, maybe all through the summer!”
“You’re kidding.”
“Cross my boob!” she did with her free hand, finger-flicking the nipple. “Gruncle Stan already fixed it up with Mom. The Falls is so out of the way that he says there’s no cases of the pandemic there so far. None! Zip! We’ll be out of her way while she takes care of Dad down here, and we’ll be safe up there, so she’s going for the idea.”
“I don’t believe it!”
“Believe it, dipdop. Mom's planning to surprise us tonight. So you’re gonna get to go see your dream girl!"
"How did you find out?"
"Oh, by eavesdropping and listening in behind the door while she was talking to gruncle Stan, the usual stuff. So you will be able to get togerther with Wendy, and she’s gonna expect some hot lovin’, judging from your texts and the nakedy photos you two have been sharing.”
Dipper felt suddenly hot, as if the thermostat had been reset to roast. “Have you been reading my—”
“Yes! All your texts and hers! Because you know I’m a snoop! Juicy stuff, brobro. And ooh, those photos! I like the one with you holding your dick with the little hat on it. And I know you stole that cowboy hat from my Bab’s Dream Kent! Doesn’t matter, it was a funny pic and it looked better on your dick head than on the doll dickhead. But, and this is a big but—” she rolled over onto her stomach. “By the way, is my butt big?”
“No. It’s very round and pink.”
“Aw, thanks! Where was I? Okay, frankly you’ve been performing so miserably with girls that I started to think you were, uh, kinda girly yourself, if you get what I mean.”
“I’m not gay,” Dipper said. “You should know that!”
“I did know it intellectually! Still, it was a relief to see you and Wendy sending sizzling hot grope fantasies to each other! And I’ve had my ear up against your door listening in when you were jacking off. ‘Oh, Wendy, your pussy is so hot and tight!’”
“Please don’t talk about it.”
Mabel ignored that and said, “However, since you’re clueless in the up close and personal girl stuff, you’re gonna need some practice to be the kind of lover that Wendy wants and deserves, am I right? You don’t want to disappoint her? To leave her hanging?”
“I—”
“Don’t answer that, of course I’m right. So what I propose to do is to help you rehearse. I know the thought of doing the big F with me squicks you, so I'm thinking we can do everything except you know, penetration. No dick in my pussy. Not that it would bother me all that much, but I know it would drive you nutso. Anyhow you have your right hand, and me, I have a way of compensating. I’ve got Mr. Buzzy!”
Dipper felt dizzy. “What? Who?”
“It’s a vibrator!” Mabel said. “About yea long, firm but really soft, runs on AA batteries, and last fall I popped my own cherry with it since I couldn’t get a guy to do it for me. Didn't bleed as much as the girls at school said it would—”
"No details, please," groaned Dipper.
"It was no big deal, and after the first time, my vibe started to make me feel really nice. I named him Mr. Buzzy because he buzzes! You can use him on me later to see how everything works down there. Meanwhile, I’ll get you used to handjobs, and you can finger me off, and maybe I’ll give you a BJ and you can eat me out—are you sure that’s right? Sounds like you take me to a restaurant.”
“No, ‘eating out’ a girl means performing cunnilingus.”
She gave him a suspicious squint. “You just made that up.”
"No I didn't!"
"You sure? Sounds like you're not spelling it right. Shouldn't it be see-you-en-tee-somethint?"
"It isn't." Dipper spelled out the real word. “It’s in the dictionary.”
“I’ll check later. Now, Dipper, if I do this for you—get you used to doing sex stuff with a girl prior to you getting together with Wendy—you’ll also be giving me feedback on my techniques, okay? So I’ll be all practiced and ready too when you help me seduce my dream guy.”
“Who's that?”
“How should I know? I’ll know him when I meet him! And I want you on my side. Encourage him, reassure him it’s all right to ravish me, and help me set him up. Okay? Are we agreed?”
She circled his dick with her fingers and began to move them up and down, so slowly, so lightly. He started to get hard. “Mabel—”
Mabel had a dreamy, happy expression. “This feels so different from the way I expected, but interesting. Softy-hardy, not all that much like Mr. Buzzy, though I like the way it throbs. Yours is so nice and warm, too. Do we have a deal? If it’s OK, just a handjob to begin with, unless you want to go a little further. Then later, in private up in the Falls, we can do all the other stuff!”
“Mabel—”
“How does dick taste?”
He made a face. “How should I know?”
“Huh. I’ve licked Mr. Buzzy after he’s been way up in there, getting all wet. I think my pussy tastes pretty good. You haven’t tried to—”
“No!”
“In the manga the girls always go, ‘As expected, your dick is very smelly.’ And they go on and on about smegma. Do you have one?”
“It’s a waxy substance, and no, I don’t have any. It’s congealed sweat and, um, semen and stuff. Guys don’t get it unless they don’t wash their penises. And I do. Wash. A shower every day.”
Mabel said, “I’ll let you know once I do a taste test, but I’m not jacked up to that point yet.” She put the flat of her palm over the crown of his dick and made circles. “How’s that? It’s getting slippery. Is it nice?”
Dipper took a deep breath. “It feels good, all right?” He paused, groaned a little, and then asked, “You promise you and I won’t, you know, go all the way? And all I have to do is help you, uh, woo a guy?”
“No fucky-fucky, and help me with the guy. Well, I mean, help me get his ass in bed once I find him, then just leave me alone with him. Show me what feels good to a guy so I’ll know how to handle all that stuff. I’ll do the woo! Deal?”
Reluctantly, Dipper said, “I guess. Ouch!”
“I can squeeze until this thing wilts like a steamed carrot,” she warned. “Say it! Do we have a Deal?”
“Deal! Deal!”
Grinning, Mabel loosened her grip but at the same time started to pump faster. “Let's shake on it!”
