VOICE-OVER: In THREE WEEKS, catch another Club 33 exclusive adult-rated episode of "Gravity Falls!"
CUT TO: Mabel, dressed in a red sweater with a sweater with a golden lion's head on it, excitedly holds up an invitation to Dipper. "Look, Dipper, I've been invited to Gravity Falls Camp for the Gifted!" Dipper asks, "Is that even a thing?" "Of course? Who would lie about something like that?"
CUT TO: In the woods on the other side of town from the Shack,, Mabel shows up and calls out hesitantly, only to be surrounded by Pacifica and her cronies, who start tearing off her clothes.
CUT TO: She tries to sneak through the streets, completely naked, covering herself with whatever she can find. She tiptoes to a payphone and calls on it. "Dipper, I need you to pick me up! And bring a sweater!"
CUT TO: Dipper is comforting a crying Mabel, who is now wearing a purple sweater with a star on it. "Don't worry, I think it's time we teach Pacifica a lesson." Mabel shakes her head, "She's untouchable!" "Nobody's untouchable!"
CUT TO: Soos handing a bag of ice each to Mabel and Dipper. "What's this for?" Dipper asks. "I only know two things about revenge, and one of them is that it's a dish best served cold." Mabel asks, "What's the other one?" He hands them a shovel and says, "Before you start, you're supposed to dig two graves first. I guess it's so you can dispose of the body and any witnesses quickly even if you're all tuckered out doing the killing." "We're not planning on killing anybody," Mabel says. "It never hurts to keep your options open," Soos points out.
CUT TO: The twins stand in a creepy outdoor temple surrounded by totem poles that seem to have boners. Mabel is holding what looks like a stone head-dress, while Dipper consults his book. "This is supposed to summon a horned spirit of justice that we can use to teach these girls a lesson," Dipper says. Mabel says "Jackpot!" and puts it on.
CUT TO: Pacifica is naked, bound to a stone slab, in the prone position, her torso raised enough to see her pink nipples. Mabel, wearing the magical headdress, and the purple star sweater, is fucking her ass from behind using a strap-on. Her eyes are a swirling green vortex of hypnotism and unthinking passion and her mouth is open in a smile that shows her braces-covered teeth. Behind them, Dipper watches in shock as he reads from his book, and is shouting, "Oh no! I misread the handwriting... it's not a horned spirit of justice, it's a horny spirit of justice!"

Mabel had left the suggestion dangling, and it felt like approximately 2 minutes had passed before Dipper could respond. And to his surprise, the erection wasn't going away, it was stubbornly growing more powerful, no matter how wrong he knew the suggestion was. "But we can't... you're my sister. And I'm your brother. Both! Even if it was just one or the other, I'm pretty sure we can't have sex."
"I'm pretty sure we can," Mabel said. "Stan explained the whole process to me once," and, her features going troubled for a moment, "in pretty disturbing detail, when he thought I was you. It's pretty much just sticking tab A into slot B. I can walk you through it, if you want."
"No, I know how it works it's just... we're not supposed to."
"If there's one great thing about this town it's that we've done loads of things we're not supposed to. We messed with the time-space continuum! What's a little incest next to that, right? We've slept in the same bed before," she added. "This will just be like... sleeping a little closer."
She had a point. "I guess I have already been inside of you..."
"That's the spirit, Dipper! And come on, don't tell me you didn't peek while we were switched."
He had, but not for very long. Somehow he never expected Mabel did. "You did?"
"I had to go to the bathroom, and that thing grows when you least expect it. And it's way bigger than I remembered." She looked down at the bulge between his legs. "Look, there it grows again!" Mabel used one finger to tap at the head of his dick, through his clothes, making Dipper flinch, and released it so it would bounce back out as she barked out a "Wop!" Moments later, she continued with, "I guess puberty's being pretty kind to you, huh?"
He rubbed the back of his neck nervously. "Actually... you remember that size-changing flashlight?"
Mabel grinned and punched him playfully on the shoulder. "Dummy... you should have told me. I could have had boobs like Pacifica." She cradled that hypothetical bust line with her hands to demonstrate. Before he could tell her she didn't need them, she asked, "So, are we going to do this? Gideon could be on his way here any second. And who knows when Stan and Soos will be back?"
Dipper felt her hands go to his crotch again, this time lightly rubbing his erection through his shorts as it strained to meet her like an eager puppy. There was no hiding it, he wanted something... hell, maybe if he wasn't a virgin he wouldn't get all stupid around girls. The idea started to make a lot of sense. "Okay," he said with a sigh in his voice. "I guess we have to. For Randy."
She surprised him with a hug of startling force. "Thank you, Dipper! Just... give me a minute to get myself ready... I'll be in our room." With one quick motion, she stood up and ran inside, leaving Dipper with the unicorn.
He looked it in the eye. "You're going to follow her inside and watch us, aren't you?" As if the beast heard him, Randy walked up the steps and through the open door. "Of course. As if this wasn't awkward enough."
***
Stan was finally ready to make his move. Moe was still with Soos, the bartender was busy serving Manly Dan, and Moe's son was nowhere to be seen, so he snuck over to the office, slipped inside, and began searching. He checked shelves first, then moved to the desk. It had to be there somewhere.
"Looking for something?" Stan looked up at the door. It was Moe's jug-shaped son, who wanted to be called Klein.
If Stan was capable of shame, he'd be feeling it then, but instead, he just said, "I dropped my keys in here earlier."
"Right." The sarcastic stretching of the word made it clear he didn't buy it in the slightest.
He looked up from his search and decided to go for broke, give up the pretense. "Hey, you're probably at the right age to hate your parents. Want to help me stick it to your dad?"
That seemed to get him interested. He pursed his lips. "What do you have in mind?"
"Gold Chains for Old Men magazine is about to do its annual '50 Gaudy Guys' edition..."
"And my dad has been Mister Oregon five years running," Klein finished. "You want... the ultimate thumb ring." As he said it, a vision of the thing came instantly to mind. Gold, with almost a face on it made of two diamonds for eyes and something that looked an awful lot like a ruby, serving as the nose. The mouth was just a line in the gold. And, at least in the vision, the whole thing glowed with an otherworldly light.
"Yeah. I noticed he doesn't wear it anymore, and when I banged your mom..." catching a glare from the kid, he quickly added, "'s favorite maid, she told me that his hands get too swollen to wear it every day. But I know he'll slip it on right before the Oregon finals. So, tell me where it is and there's.... fifty bucks in it for you."
"The ring's worth a thousand dollars."
"Okay, sixty." He could tell that wasn't going to work either, so he shrugged dismissively. "Look, kid, I'm not going to steal it, I just need to keep it away from him for a few days." He completely planned on stealing it permanently.
"Even if you take it, you're never going to win."
"Win? You think I want to win? Listen, when you get to be my age, you don't care about winning... you just want your peers to lose! Come on, have some pity on an old man." He grinned self-effacingly and got ready to punch the kid in the face. He knew just how to do it that he'd knock the boy unconscious with only about a twenty percent chance it would kill him.
"He keeps the ring in his wall safe, behind the picture," the kid said finally. "I'll make you a deal, if you can get in, you can have the ring. I want everything else."
That piqued his interest. "What else is in there?" He could still punch the kid.
"Some saving bonds in my name. The old fart's been holding out on me, wants me to finish my education. But I don't want to wait. I'm ready to open my own place, right now, with none of my father's retarded hang-ups, and it'll make more money than he ever did. I'll call it... Klein's Butt-Holes! Get it?"
Stan stared at the kid's wide eyes and eager grin, like he was waiting for Stan to laugh along. "I don't get it," he said. "But I'm in." Klein moved into the room and helped removed the picture from the wall, and Stan studied the inset safe with glee. "Ah, a Palindrome 1881. This shouldn't be too hard... I might not even have to get my dynamite!"
***
"Mabel? You ready?" The nervous voice came from the other side of the door to their attic bedroom.
Mabel checked herself in the mirror, and took a deep breath. This was it, she told herself. Your whole life might depend on tonight. She'd gotten herself as pretty as she could and put on deodorant. She would have liked to take time for a whole shower, but she owed it to Randy to not dawdle... Gideon really might be on his way there at any moment. So she'd just quickly run into the bathroom to wash her hands, face, armpits, and pussy, and then returned to finish up in her room. She opened up the door. "Okay."
On the other side, Dipper was holding Randy back. The unicorn had tried to get in earlier, but the door was already closed. Now, Dipper had the difficult task of getting into the room without letting the unicorn follow. It was a complicated maneuver, and Randy got partway inside several times, only for Dipper to push him back. It was worse than back home when he'd try to keep the cat out of the bathroom while he was whizzing. Mabel always just let the cat watch.
Finally, though, Dipper managed to close the door with Randy on the other side... still knocking his hooves against the wood and making impatient snorts, but he couldn't get in. Once it was done, her brother finally turned to face her. He still looked nervous, like he didn't want this, and that broke Mabel's heart, but at least it was going to happen. Suddenly, he tilted his head and squinted at her. "Did you just... change your sweater?"
Not just her sweater, her headband too, and her underwear, but the sweater was the most obvious one. It was now a cyan-colored sweater with a cartoon strawberry on it. Her headband matched the color, of course. "Of course," she said. "You're going to take my berry, right? So, berry sweater."
"I think the word is 'cherry', Mabel."
She put on her fake-angry face. "Fine, you want me to say it? I don't have the right sweater for this event! This was the closest I could find, and I didn't have time to sew a new one." She spun around and smiled again. "How do I look?"
"You look fine... I guess we should get undressed, though. That IS how it usually works." He took the hat off his head and tossed it over on his bed. Mabel bit her lip. "What?" he asked when he noticed it.
"It's just... could you do me a favor?"
"I thought I was already doing you a favor..."
She frowned, almost wanting to call it off. "No, right now we're doing RANDY a favor."
"Okay, fine... what do you want?"
"You don't have to do it..." He looked at her impatiently. "It might sound a little weird."
"Will you just tell me what it is?" he snapped.
She took a breath. "Dipper... this is my first time."
His voice softened, like he was ashamed of the outburst. "Mine too."
"I know but... I always wanted my first time to be... romantic. Like, with French kissing, and making out. I know you're..." She corrected herself quickly, "I know we're only doing this because we have to, but... can we maybe pretend. You can even imagine I'm somebody else." She then pulled off a pitch-perfect Wendy impression, so good that if it were a movie, you'd think they just dubbed in somebody else's voice, "Hey Dipper, want to make out?" It was one of her hidden talents, although she had to know the person really well.
"No, don't do Wendy," he said quickly, surprising Mabel. Was it too much to hope that he was getting over her? No... it probably would just remind him of what she and Robbie had probably done tonight.
"I can try Soos if you'd like, but," she switched to Soos-speak, "I think it would spoil the mood, dood."
Dipper laughed a little, which was good, it broke the tension. "You dork. I'll play along... you don't need to do any funny voices." He took a step towards her. Than another. Mabel's heart was racing and she felt her knees shaking... put the two together and it felt like her whole body was out of control. They were practically nose to nose, now. He leaned forward, and both of them closed their eyes as they tilted their heads.
They bumped into each other. Both had tilted the same way. "Ow..." they said at once, and then chuckled nervously. "How about you go this way," he said with a nod of his head and then jerked in the other direction, "and I'll go this way." She nodded quickly, and both closed their eyes again.
Their lips met, an electric sensation, requiring only a little bit of adjustment to get them perfectly aligned, and then she opened her mouth. His opened too, a moment later, and their tongues grazed past each other. They were kissing... and to Mabel, it felt phenomenal. She made a little moan, and then she heard a sound from him which made her even more excited, and she slipped her tongue under his, their saliva mixing. Her right hand rose to his cheek, and his left went on her shoulder, then his right settled on her hip, and she put her left on his shoulder... almost but not quite holding each other like lovers.
Their tongues continued to play, like it was dance, or a kind of wrestling match with neither of them remaining pinned for long. I can't believe it, she thought, we're actually kissing, with tongue... our spit is going everywhere....
She couldn't help it, she laughed and pulled away, a long strand of saliva, his or hers, dangling between them for a second. "Haha, sloppy makeouts!" she blurted out, loudly.
"Mabel, shhh..." Dipper whispered, putting both his hands up over her mouth while he looked around nervously.
"What are you worried about?" Mabel asked, playfully fighting his hands away. "Nobody's home, we would have heard them pull up." He shrugged. She leaned forward and kissed him again, a soft one, landing above his lips, near his nose. "So, do you want to try French kissing next?"
Dipper looked momentarily confused. "Mabel..." he said. "That WAS French kissing."
She blushed a little more than usual. "Oh, right, that's what I meant, do you want to try it some more?"
Her brother now put on a smug and satisfied expression. "What did you think it meant? Come on, tell the truth."
"I certainly didn't think it was making out while I had a beret and you had a cheesy mustache, if that's what you're thinking..." and she grabbed the beret and temporary marker off her bed and stuffed it underneath. She was a little embarrassed, but not really trying to seriously lie about her mistake... Dipper was one of the few people who liked her silly side... and mistakes around him didn't seem so serious. It was one of the things she loved about being with him.
True to form, he put one finger under his nose like it was a pretend mustache. "Ooh la la, ma petite jambon." She grinned, despite not knowing what he meant. He probably didn't know either. Black and White Period Piece Old Lady Boring Movie Channel sometimes played strange French movies and the twins would cover the subtitles, listen to the words and put in their own translations. It was the kind of thing that made Mabel wish he could be her boyfriend, and they could have that kind of fun forever.
"Well if we've already done French kissing..." She stood up and grabbed the bottom of her skirt and began to raise it, very, very slowly. She hadn't intended it to go that slowly, but she was savoring the way his eyes were locked on her legs, following the hemline every time it rose, his face getting a little red and sweaty, his tongue moistening his lips.
Finally, she revealed her new panties... nothing all that fancy, white, with a pink trim, and, centered right above her pussy, a cartoon flower. She liked her underwear to have wild designs on them, just like her sweaters, but nobody else ever got to see them, except Candy and Grenda. And this time, she chose this one specially. "Do you think you're ready to deflower me?"
***
Soos had actually been in strip clubs before, although not this particular one. Of the ones he'd been in, he'd never been in a private room... though he'd watched his cousin Reggie go in once and come out with all kinds of stories about what he did with the girls in there.
He'd always imagined the private rooms as marvelous, elegant chambers with really comfortable couches, the kind that you can sink in completely and really mold themselves to your ass, and veils everywhere, and soft lighting and maybe even a disco ball. The reality was different, at least in this place. Red felt covered the walls and there was a stiff red chair, and the whole place smelled like stale beer. Moe Bius pushed him towards the chair and had him sit. "This is our best private room. Don't worry, we can pretty it up if you decide to film here. Girls? Show him your stuff." The girls began dancing around him sensually moving their hips, two of them practically crawling on him. One had a bra on, the others were just in their panties, which was what they were in when Moe called them to join them. Beth was dark-skinned, the others were white, Lady Bi being a busty redhead who reminded Soos a little too much of Wendy, Electra having black hair and was the one who started out with the bra, Gumdrops with a bright pink wig, and Easy being a cheerful looking blonde. She was one of the ones crawling over him. "You know our house policy, right?"
"Yeah something about no action on the backside."
"Right, you know why?" Soos shook his head. "Because everybody needs a gimmick. And ass stuff is disgusting anyway. I had three quarters of my colon removed, and I don't miss it. But for you, I'll make an exception... if you agree to use my establishment in your little porn movie."
"I'll think about it." Soos tried his very best to look sly and confident. Stan wanted him to stall, and as much as he didn't like being dragged into this, he wanted to do his best for him.
"Girls, give him a little more to think about... you want to break into porn... professional porn, I mean, this guy's your shot." Electra removed her bra, revealing brownish areolas with bead-like nipples. Gumdrops stroked his pants, which were beginning to bulge up. Beth ran her fingers up and down the far side of his head while pressing her chest into the side of his face.
"So, Mister," Gumdrops said, "Which of us do you want to fuck first?"
"Geez, I don't know," Soos said. "You're all hot, but... we don't have to have sex right away you know..."
Lady Bi grinned. "Oh, I get it... he wants a little girl on girl action first." She grabbed Electra by the hair and pulled the other girl to her own lips, and the two began making out with tongue. Lady Bi's hands dropped into Electra's panties, fingers digging in deep.
Soos couldn't help but stare at the action... he always did enjoy lesbian porn, it was like, they really seemed to enjoy it. And here as well, the redhead seemed hungry for Electra's lips. His cock grew even bigger... he was always a little slow to arouse, it's just that getting that much blood diverted took time, and if it happened all at once he'd probably collapse from the sudden lack of oxygen to the brain.
"Somebody's happy!" Gumdrop exclaimed, cupping his balls. "Very happy! Why don't we take a peek..."
Soos was too busy watching the girl-on-girl show, he barely noticed Gumdrop unzipping his shorts and pulling out his penis... but the penis noticed. Direct contact with another human being made it grow even more larger and more rigid. "Wow, no wonder you went into porn," Gumdrops said. "This must be the largest penis I've ever seen!"
Soos blushed a little. "It's not that big."
"It really is," Beth agreed. She gazed at it with some kind of awe. "It might even be the world's largest penis. I don't think I could even handle this right now, it'd tear me apart. Easy, you used to do donkey shows, you fuck him first."
Easy was watching the lesbian show too, but then looked over and her eyes practically lit up. "Ooh, yum yum."
Gumdrops grinned. "I'd better slick him up for you," and ran her tongue up and down his shaft, then popped the bulbous head inside her mouth and sucked for a while. It managed to get even bigger, so big she couldn't get it down her throat. Moe glanced over and grinned at Soos, a grin that spoke volumes, like he was saying, "You see what great girls I've got here? You like?"
Easy pushed Gumdrops away after her tongue had been working Soos for almost a minute. "Okay, stop being greedy, let me on..."
Soos, though, was starting to feel a little sick... sure, he was horny, he wanted to fuck, but not quite in this way. As the girls repositioned to give Easy room to straddle his legs, and he now had a different set of boobs on each side of his head, he put his hands out to keep her at bay a little. "We don't have to go right to the sex. We can, you know, get to know each other a little first."
"I know all I need to know." She grabbed his huge dick, her hand not even able to encircle half its girth, and waggled it back and forth. "Besides, we go way back. We used to played video games together. Don't you recognize me? I lived next door to Bud? You always called me 'little dood.'" Oh, shit, Soos thought. He didn't know her well, but he remembered her, always trying to tag along with his friends, but she was a good kid, or at least he thought she was. "God, if I knew you were this endowed back then I would have been all over your analog stick."
"Wait," Moe said. "You already know this guy?"
"Sure. Soos went to the same high school as me. Not at the same time, he was a senior while I was in middle school, but I was banging most of the football team back then, so we had friends in common."
Moe was now clearly suspicious. "I thought your name was Barry."
Everything was falling apart. Soos pushed Easy off him, his erection now faded anyway, and stood up. "You know, dood, I think I'll take a rain check on the whole sex thing, I really need to, uh, feed my car." He managed to get to his feet and shuffled off towards the door while he attempted to stuff himself back in his pants and zip up.
"Oh, okay," Easy called after him. "Hey, you still work at the Mystery Shack? Cause I could drop by..."
"The Mystery Shack?" Moe growled, as Soos made it to the door and slipped out. He waddled back into the main floor of the strip club, trying not to look back, but he heard Moe's cane following behind him. Stan was nowhere to be seen.
***
"Are you just going to stare at it," Mabel asked. "Or are you going to take them off?"
Dipper had no idea he was staring, or for how long he had been... the little flower panties just caught him in some kind of spell. They were tight enough to make out the basic shape of her mound, even with a little fabric digging in to the cleft, and somehow it was the hottest thing he'd ever seen.
It was insane. Not just what they were about to do, but that such a simple, practically innocent sight was affecting him so much. He'd seen Mabel in her underwear before... recently he'd even peeked at her pussy itself, when he was temporarily in her body. But that was just a brief look out of curiosity, and seeing Mabel in her underwear didn't carry any sexual content before this moment.
It was like he was seeing her for the first time... hat her legs and hips met in an area that was suddenly, powerfully erotic. Like every previous time he'd seen her in underwear, or even a tight swimsuit, he'd been holding back and mentally covering her with a weird, unformed body that hid her real shape, just for his own safety, because if he acknowledged what she really looked like, he'd be turned on, and he couldn't afford to be turned on by his sister, not when they shared a room.
Until now, where it was somehow okay, the normal rules were suspended, and she was no longer a cartoon kidney-bean with legs, she was a young woman, a sexy thing that wanted him to take her clothes off and have sex with her. "Dipper?" his sister asked again. "If you're that fascinated by the panties, maybe you should keep them for yourself. Or do you want me to be the one to take them off?"
"No, I'll do it," he said, and got on his knees, then put his trembling hands on her thighs and rested his fingertips on the top of her panties. One last look, and he pulled them down.
It was exactly as it was in when he saw it from Mabel's own eyes, and exactly how it looked in the flashback he experienced while Mabel told him about Wendy teaching her how to masturbate. The only difference was, it a little puffier, like it was blushing, and there was a glistening slickness between them. Was she turned on? Well, he certainly was. He took a deep breath, and he was close enough to smell... except it didn't really smell like anything, except that strange almost subliminal smell that he sometimes perceived around girls... turned up to 1000, so that it was almost superliminal, even though he couldn't quite identify what it was or even what it was close to.
He wanted to lose himself in it, stay with the smell forever. Even taste it... well, why not? Mabel said she wanted the romantic treatment, and he'd heard couples do that. Without warning her, he leaned forward to give it a kiss and even slipped her a little tongue. It tasted a little like sweat, with a sweet and sour overtone, but he liked it... and Mabel seemed to like the action. "Oh my god, Dipper..." she squealed.
"Sorry..." he said automatically.
"Don't ever apologize for that..." She pushed his head back and he took another French kiss of her slit. He wiggled his tongue around and inside, until she pulled away. "As much as I want you to continue, we really need to speed this up." She pulled her sweater off, leaving her in a light pink t-shirt and her skirt. She sat down on the bed and removed her socks, then stood once more. The skirt fell next, leaving her completely bottomless. "You could get undressed too, you know. I mean, if you're going to stop and stare at me for five minutes every time I take something off, we're never going to finish before Gideon gets here."
"Right, right..." He tore off his blue vest and then pulled his red shirt over his head, sucking in his gut automatically. He shouldn't have to feel self-conscious around his sister, but right now, in this moment, he did, as bad as he ever had with Wendy. He pulled his shorts down, leaving him in his briefs, and while kicking off the shorts, removed his own shoes and socks.
The simple briefs he was wearing were white... or at least, they started that way, he wasn't up on laundry as he should have been, and now that ashamed him a lot more than it ever had before. He might have been more embarrassed about showing her his cock, but she'd already given him a good review on that, so ditching the underwear became his top priority. He bent down, pulled them off, and kicked them under his bed.
Now he stood before his sister, naked, sucking in his chest, and with a huge erection, particularly huge for a boy his size, although he still worried it might be too small.
Mabel evidently had the opposite worry. "You know, that looks way bigger when you're looking at it from over here and not up top."
"Maybe I went a little crazy with the flashlight," he admitted. "We don't have to do this..."
"Oh yes we do." She was pretty firm on that.
"Okay then..." he looked her up and down... she was still wearing the pink t-shirt. "You going to leave that on?"
Mabel shrugged, not willing to meet his eye. "It's not like there's anything much to see..."
And yet, there was... with her sweater off, and with him actually looking for once, he noticed that she had tiny bumps where he was pretty much flat. That was one thing he hadn't seen... his sister sometimes changed in the same room with him, but she always took care to turn away and he would usually look away as well. "Come on, I want to..."
She took a breath and slowly pulled the shirt over her head, then tossed her hair back to the disarrayed strands back into a proper position. Yes, it was no illusion of the T-shirt, there were bumps, little buds, topped with a pink nipple like a tiny blister. That didn't seem to show through the shirt, so maybe that was new. "You don't have to stare, I know they're small."
"No, it's not that," he said quickly. "They're beautiful. I never noticed." She shrugged. "Okay, let's do this." He closed the distance between them, his dick bouncing along with his step.
"Don't forget the romance," Mabel said. "By the time we're done, I'd better be able to tell what you had for breakfast."
"Mabel, you know what I had for breakfast. You were there. We..." He didn't get to finish, because Mabel leaned forward and kissed him on the mouth again, a soft one, quick, like it was just to shut him up. It worked, but only long enough for her to pull her soft lips away from his. "Besides, didn't you taste it the first time?"
"I've got a short memory. Remind me." They kissed again, this time mouths opening and their tongue intertwining again. She still tasted faintly like artificial cheese flavoring, although she had the first time they'd kissed too. Now, though, there was a significant difference, not in taste, but in sensation. This time it was like a whole new world, with them being naked, instead of just feeling the slight pressure of their clothes pressing together, he felt only warm flesh on his own, and his rigid dick bumped up between their bellies. That sensation was already better than masturbation, but it was also a subtle torture, knowing there was more powerful things coming, and his cock grew and shrank in pulses like it was straining free of confinement.
Mabel broke the kiss and looked down at his dick, and then fell back onto the bed, in a position somewhere between sitting and lying down, using one elbow for support, and her knees bent, feet hanging off. "Hurry up and put it in me." She spread her legs to give him room to get in between.
He sidled up, took his shaft in his hand and aimed the head. It bumped the slit but didn't slide inside, just mashed the exquisitely soft flesh into her body and spread the opening a little. Mabel sucked in her breath at the contact.
Dipper angled the head down, swirling it around, like he was digging himself a hole... in some ways, he was. The lips parted with the motion and stayed parted, providing him a bigger target. He pressed forward again and this time, he could feel as well as see, if he kept going forward, it was going to slip in. He looked Mabel in the eye, and she nodded subtly, and he pushed forward.
It was a tight fit, but the large head finally popped inside... Mabel winced for a moment, but once it was through, the widest part, it was a little more comfortable. "I guess that probably did it. Do you want to stop and see if we can still see Randy?" He didn't want to stop, but this was weird enough.
"Don't you know anything, Dipper?" Mabel asked. "It doesn't count as real sex unless you go all the way in. And go in and out a few times."
He'd never heard that before. But then, he didn't get the sex talk from Stan that she did. "Are you sure you can take it?"
"I can take anything you can give me." She leaned forward long enough to snatch his hand, and her fingers intertwined with his as she pulled him with surprising force... he could have resisted were he ready, but he wasn't, and so he found himself on top of her, although still inside her, now deeper than ever.
She winced, mouth opening, braces glittering by the ceiling light, and he was afraid he'd hurt you. "Mabel, are you okay?"
"I'm fine," she said, with a voice that sounded afraid to breath. Her hand squeezed his tightly. "Just wasn't expecting... that much cock!" Her using the word made his penis jerk and give her a little more. "Kiss me again," she said urgently, as, down there, she squeezed around him. "When we're making out, it takes my mind off things."
He kissed her, put his tongue inside her, one hand still holding hers, the other lying free on the bed. At first he'd been trying not to move, but before long his hips started moving of their own accord, a gentle rocking motion. When he realized what he was doing, he tried to slow down, only to feel Mabel's thighs at his sides, pulling him in and out, keeping it going. She had said they had to go in and out a few times, he decided, so kept going, picking up the pace, and before long, it felt so good that he couldn't have stopped if he wanted to. It was a more all-encompassing sensation than his hand had been, and it was all wet and warm, he didn't want to ever stop. He knew sex was important to people, but now he understood how great it felt, and a shudder of guilt went through him that he was experiencing it with his own sister. He was supposed to be pretending she was somebody else, but he hadn't done any imagining, in his mind as well as with his body, he was having sex with Mabel, and loving it.
What happened after? The question suddenly occurred to him, quieting his passion, preventing it from reaching the boiling point that should have been coming already. Would they just agree to pretend it never happened? He guessed they'd have to.... but he didn't want to, but it was the way things worked. Brothers and sisters never had sex, except maybe in an emergency like this. Once the emergency was over, it would go back to business as usual... they'd still be as close as they ever were, he prayed, but no closer.
But what if? he wondered. He imagined this not being a one-time thing, imagine them becoming siblings with benefits, able to have sex any time the mood struck him. Maybe it would do Mabel some good, he rationalized, with somebody to fuck she wouldn't get all worked up about a summer romance and wind up throwing herself at creeps like 'Norman' or strange foreign men like Mermando who might secretly be part of a mermaid slave trafficking ring. Maybe he and Mabel could be the best of friends they always were during the day, and then when the lights went out, turn into lovers.
Of course, he didn't know if Mabel was loving it as much as he was. She was still kissing him, and at times almost sucking on his tongue, or occasionally, her lips, but that might be just to distract herself. He could feel little grunts through their enjoined mouths, but couldn't tell if they were pleasure or pain... in porn the girls always sounded like they were being hurt. He pulled his mouth away for a few moments and she practically squealed with one of his thrusts. He stopped, inside her all the way to the balls. "Okay, I think under any definition, you're not a virgin anymore."
She opened her eyes and looked for a moment, angry at him. "We don't know what definition the magic uses. We can't afford to stop until we've both had our orgasms."
"But if I'm hurting you."
"The only way you're hurting me is by stopping when it's getting really really good," she said. "Stop one more time before we're both done, you won't have to worry about you hurting me, you'll have to worry about me hurting you." They had still been holding hands, but Mabel now pulled his and put it right on her breast, where her nipple felt like a tiny little diamond. "Now less gabbing and more grabbing."
He did squeeze the little mini-boobs, even brought his other hand up to do both at once, and then began the slow in-and-out sawing which didn't take long to become rapid thrusting. Mabel's chipmunk squeaks began again, and now that she'd told him she was enjoying it, he didn't hold back, throwing himself into it.
"Go on, go Dipper... faster... give it to me... ah, ah, ah, ah..."
He kept going, but felt the intense vibration at the base of his dick, like he was a living volcano and he felt himself about to erupt, the lava rising towards the peak....
Mabel shouted "Abracadabra!" just like she had in the flashback, while her pussy convulsed all around him, like a milking machine, and he burst, feeling a flood of liquid leave him and enter his sister, filling up every crevice inside of her... and it felt incredible, better than any masturbation session before, enough to wipe out any other thought for a few seconds except that he was with Mabel, and that somehow that was where he was meant to be.
He let out a breath, one he didn't know he was holding, and Mabel did the same, at the same time, like they were the same person operating two bodies, and staring at each other's eyes. "You are way better than a hair brush," she said, and then grabbed him by the hair and pulled him down for another kiss, with tongue again but not as urgent, like a hello kiss between lovers... or a goodbye one.
Maybe that's what it was, Dipper wondered. One last kiss goodbye. When they broke it, she said, "I love you Dipper."
The words made his heart swell, even though he didn't know exactly how she meant it. Brothers and sisters were supposed to love each other. Whatever the case, there was only one response. "I love you too Mabel."

"Stanley!" Stan had his ear up against the safe, listening to the tumblers, while he spun the dial, but his name being called out in Moe's deep voice drew his attention. It wasn't his name, Stanford was his name, but Moe often forgot when he got angry... or deliberately used to wrong name to antagonize him. "Where are you, you good for nothing cunt?" He really sounded pissed this time.
He and Klein stared at each other. Klein's face was white as a ghost for a second, but then rapidly regained color. He shouted, feigned fear in his voice, "Dad, he's in here, I caught him trying to break into your safe! I think he wants your thumb ring!"
"You son of a bitch," Stan muttered to the kid. "And I mean that literally, your mom fucks dogs. I've got proof." He was close, but right now the safe was still firmly locked. "I should have used the dynamite," he observed, but shoulda woulda coulda. There was now no time. He made his way out of the office and spread his hands trying to look the picture of innocence, with his eye patch even flipped up. "Who are you going to believe, Moe? Me, your casual acquaintance of many years, or your worthless son?"
Moe had two bouncers out, who seemed all muscle. One held Soos by the collar... his employee now sporting a hangdog expression. "You're banned from my club, Stan. Gentlemen, escort them outside. Do not be gentle, men."
"Moe! It's all a misunderstanding!" He got himself close to the guy holding his employee, trying to sound as pathetic as possible and look as harmless an old man as possible, and then suddenly, like a cat pouncing, launched out and kicked the man right in the family jewels. The bouncer dropped Soos and doubled over in pain. "Soos!" he yelled. "Do your rabid badger!"
As though a switch had been flicked, Soos got on all fours and snarled, snapping his teeth while jerking his head forward like he was some kind of animal. The other bodyguard, the one still on his feet, drew back, and Soos pounced forward, making a growling, chittering sound. "I knew hiring that hypnotist would come in handy!" Stan said with pride, elbowing Moe like they were still old friends. Then he realized what was happening and he made for the door. "Come on, Soos!" Soos snarled one last time, and followed. "I just hope I can remember the key word to undo it."
"Oh, I wasn't actually hypnotized," Soos spoke calmly, still walking on his knees. "I just really like pretending to be a rabid badger." He snarled one last time at the guy guarding the door and they pushed past him, and then Soos got to his feet and they ran for the truck.
Just before they pulled away, Moe came out, shook his fist in the air, and shouted, "And don't ever come back!"

Mabel adjusted her dress after pulling up her panties. Dipper was on the other side of his room getting dressed. They had barely looked at each other after he finally rolled off her, like a spell was broken, or the moment of intimacy just a happy dream that it was time to wake up from.
If not for the tenderness between her legs, she might have actually thought it was a dream, or another Smile Dip flashback... though she had one other reminder of the reality of what had happened. The bottom of her panties, the parts touching her slit and thighs, were damp and slimy, and surprisingly cool, sticking in parts to her skin with the stuff Dipper left behind. It felt dirty, but a good dirty. Just like the act itself.
She looked over. Dipper had his vest back on, and was, finally, looking back at her. "So, I guess we need to find out if it did the trick."
"Yeah, I'd hate for us to have done that for nothing..." She forced out the joke. She let Dipper open the door, and they looked beyond it to the rest of the attic...
Randy was gone. "Randy? Did you disappear?" Mabel and Dipper both looked around, searching for any sign, when suddenly they heard banging from downstairs. "I guess he got bored."
They ran downstairs, and they still could see no sign of Randy. They could, however, hear a lot of bumping coming from the door. A whinny confirmed it... Randy was obviously right there, but they couldn't see him. "He's trying to get out," Dipper said. The sound of hooves retreated as Dipper got closer. "I think he's scared of us now. Unicorns don't like non-virgins, remember?"
Mabel's heart sank. "It's okay, Randy... we're still your friends..." she said, but knew deep down that they weren't, they couldn't be. Once they'd crossed that line, friendship was out of the question. She just hoped that it was only true of Randy.
Dipper walked sideways, as though he was afraid he might accidentally trip over the unicorn, or be stabbed by the horn he now couldn't see, but eventually he grabbed the doorknob and opened the door. Randy reacted immediately to his chance of freedom, and galloped out.
Mabel followed him out. "Wait, Randy! You could at least say goodbye!"
But there was no answer, he was gone. Mabel sighed, sat down on the step, and held her cheeks in her hands. After a few seconds, Dipper sat down beside her. "At least Gideon can't use you to find him, now," he said.
"I know. I don't regret it... I'm just sad," she said, and sighed again. "It seems everything and everybody I love has to leave me." Norman left by turning out to be a bunch of creepy gnomes. Then there was Mermando, who had to go and be with his family in the ocean. And now Randy.
"Not everybody," Dipper said, and he took her hand.
They looked each other deep in the eyes, for the first time since they'd had sex. But although people always said eyes were the windows to the soul, Mabel couldn't read what was in his eyes. "You mean that?"
"Of course," Dipper said. "I'm always going to be your brother."
"Oh, right," she said, trying to sound cheerful. She laughed, but her heart wasn't in it. Dipper always worried that he had been friend-zoned by Wendy. It was even worse being bro-zoned. Suddenly, she remembered something. "Oh no! I forgot to take some of Randy's hair!"
Dipper look confused for a moment, but then came to what was probably a logical conclusion. "Oh, for a souvenir."
"Yeah," Mabel said, laughing nervously. "A souvenir." No, she wasn't planning on seeing if unicorn hair could make somebody love you, not at all. Gideon was probably lying about that anyway. Remembering that little twerp, she stood up suddenly. "I guess that means there's just one thing we have left to do..."
She raced to the phone and dialed Gideon's number. He'd given it to her long ago when they first started hanging out, and she'd tried to forget it when he started getting creepy, but that just made it stick in her head more. Besides, it was easy to remember, it started with 555. As soon as he answered, she said, "Guess who just got her cherry popped just to frustrate you? That's right, it's Mabel!" She frowned in consternation. "Oh, hello Mister Gleeful. Could you put Gideon on? Thanks." She waited, bobbing her head as though there was music and glanced over at Dipper who was watching her. When she looked at him, he looked away suddenly.
"Hello Mabel." Gideon's voice still grated on her. "I'VE GOT IT, HANG UP!" he yelled suddenly, not to her, but to somebody else, probably his father. There was a clicking noise. "Hello, Mabel," he said again, his voice going sickly sweet. "I take it you've reconsidered my offer."
"No, I just called to tell you not to bother. I sent Randy away. You'll never find him. I'll never see him again, but it was worth it."
"You... you didn't."
"Didn't what? Let somebody park their baloney pony in my Mabel stable? You bet I did... and you know what? I enjoyed it."
"You little harlot," he said.
"I might even go do it again, just for fun. But don't worry, my feelings for you will never change. We'll always have me not wanting to touch you. Ta-ta!" She hung up.
"What you said about doing it again...." Dipper said. "Mabel, you know..."
"I was just making him jealous," she said, and then, trying to hide the sadness in her heart, she added. "We don't have to do it again."
"Oh, okay. Cause it'd be pretty weird." He spoke too fast, though, like he often did when he was lying, or around Wendy, and Mabel wondered... could she have read it wrong? Maybe Dipper really did want to do it again... her heart leapt at the possibility... but she needed him to make the first move. "I don't want thing to be weird between us."
"Yeah," she said as her hopes sank again. "I understand." Right then she didn't want to be around him. "I'm going to go play with Waddles for a while. Poor thing's probably been feeling jealous all day." But she didn't want to play with Waddles, what she wanted to do was descend into her Sweaterverse for a while. She'd screwed everything up.
***
Stan sat back in Soos' truck as they drove away. "All you had to do was sit there and let Moe thrust pussy in your face. I just needed five more minutes and I could have gotten that ring! If you'd shot off early I could understand, but... you didn't even get laid!"
"I'm sorry, Mr. P... I didn't mean to let you down, it's just..." They'd driven a block before he continued, "I don't know, every time I've done sex stuff, it's with someone I loved at the time. And maybe you think it's stupid of me, but... I don't want to break that streak."
"You're right, that is stupid." Seeing Soos' downcast face, Stan's expression softened and he laid a hand on the manchild's shoulder. "But it's also very... sweet." Naive, but sweet.
"You think so?"
"Yeah, you're... a good guy, Soos." He beamed at that, his mouth open in a smile that revealed his jagged, pointy teeth. Teeth like those, guy should take any sex he could get. That's part of why he came up with this plan, it wasn't just to get the ring, he thought he'd give Soos a little thrill as well... and now it just made him a little grouchy again. "So if you had no intention of doing anything fun, why did you agree to come to the strip club with me?"
"Because you offered, and that really touched me. You know, in my heart. And I don't have anything against watching naked girls. Their boobies sway hypnotically. And then I found out you weren't really rewarding me, you just needed me to run a scam, I still wanted to help out because... you're my best friend, dood. But I couldn't. Sorry."
And now he felt like shit. Which was a rare feeling for Stanford Pines. "It's okay. Look, everything I said before? About you deserving a real reward? It was true, I was just killing two birds with one stone. Except I didn't manage to kill either fucking bird." He exhaled a deep breath. "But the night's still young. You choose your reward. The sky's the limit." He reached into his pocket. "As long as the sky is under $30."
That perked Soos up. His head came suddenly erect, like a startled squirrel. "Really? Anything at all?"
"Within reason. And, might I suggest a crisp ten dollar bill? It's what all the kids like these days!"
"There is one thing I'd like do with you... if you'd be up for it." Soos seemed hesitant, but hopeful.
"It's not gay, is it?"
***
Stan stood back to back with Soos, each wearing an elaborate harness and holding a plastic gun-shaped object. "Okay, I'm going to penetrate their zone. Just keep it tight, and cover my ass," Soos said.
"I don't know, this still feels pretty gay to me," Stan grumbled, but raised his weapon, spotting the little laser beam in the misty room. "But go ahead."
Soos moved with lightning quickness into the room, shooting at the chests of anybody he saw. Stan did his best to follow and shoot anybody Soos didn't see. And the first time he tagged a pimply faced teenager in the chest and saw their vest light up, he laughed. He laughed again when he raised the beam up.
"Ow, my eye!"
Stan grinned. "Haha, eat laser, sucker!"
Okay, maybe it wasn't so bad.

It was bedtime, and though the twins had managed to stay mostly apart since sending Randy away, it was time for them to come together again, and Dipper was once again feeling the shame, the uncertainty, how was he supposed to behave. He pretended to be reading when Mabel came out of the bathroom, and then when he looked up, she was wearing only panties and getting out her purple nightgown, the one with the old-style computer disk on it. Dipper gulped and looked back to his book suddenly, although his erection grew. She wasn't even facing him, it was ridiculous, but her naked back and her round, panty-covered rear end got him all hot and sweaty again.
"Where do you think Randy is right now?" she asked, and he dared a look... she was safely wearing the nightgown. She was also sitting on her bed, her legs open, leaving an inviting gap between her legs, where you could look right up the nightie and see the familiar flower on the front of her panties, if you were to look.
Don't look, he told himself, but his eyes remained focused there, as he said. "I don't know. With his family, I guess. Where he belongs."
"I don't think he had a family."
He finally managed to look back to his book. "I think he did. Maybe he's even got a twin sister unicorn out there."
He meant it to be cheerful, but it backfired, because now Mabel sounded sad. "Then why would he leave her to come with me?" She crossed her legs, now making easier to see her panties, with her nightgown riding up, but he hadn't noticed it yet.
"Don't read too much into it, Mabel... it's probably just animal instinct." Now he noticed that he could see her panties, and began to stare again. She caught him at it. He turned away suddenly and tossed his book on the nightstand. "Well, good night!" He rolled off and ran to the light, turned it off, and then hopped back in bed.
They were quiet for a while, but then he heard his sister's voice. "Dipper?" He stared at the ceiling, pretending he didn't hear her. "It got weird, didn't it?"
"Yeah," he admitted, turning on his side to look over at her across the darkened room. "I guess it did."
"What are we going to do about it?"
"I don't know.... if we pretend it never happened, I'm sure it'll go back to normal, eventually."
She didn't answer, and he rolled away.
Soon, he began to hear a shuffling noise, like she was rearranging the covers of her bed or something, or tossing and turning, trying to get to sleep. He didn't look over, still working through his own emotional turmoil. That's what was making it weird, he was having all these weird feelings, and Mabel must be picking up on it. They were the same kind of feelings he recently had for Wendy, and so, when he was around her, he now never knew what to say. It was crazy. And scary.
With Wendy, he was always putting on a mask... and so even if she didn't like him, it would have hurt him, but at least he could tell himself she never saw the real Dipper. But Mabel, she knew the real Dipper, flaws and all, more than any human being could. If she liked him, like-liked him, it meant a lot more... but that was impossible, wasn't it? And if she decided, as he knew she must, that she couldn't love him in that way, what did that say about him? That he really was as unlikeable as he always felt.
The thing was, though, he thought he might really be starting to love her, and not just in the way he always had. He'd already thought it, if Wendy hadn't liked him, he "would have" been hurt. But now, the thought didn't even bother him. He was obsessing over what Mabel, his own sister, might be thinking about him, exactly like he used to do with Wendy. This must be what it felt like when sanity fails.
What happened if he never stopped feeling this way? Mabel would grow up and find somebody eventually and he would be hung up on her forever. He'd probably wind up doing something crazy like writing a book about their adventures in Gravity Falls and making her ridiculously loveable. Unless they could just pretend it never happened, and maybe he could convince himself of that, and the feelings would fade away.
Mabel's voice came to him in a whisper. "I don't think pretending it never happened is going to work, Dipper."
Of course. It was no surprise she could practically read his mind. He gulped nervously. "Do you have a better idea?"
"As a matter of fact..."
She was suddenly beside him, with one smooth motion she'd slipped underneath his own blanket. He hadn't been watching her, she must have been sitting up when she'd last spoken. "If sex made things weird, we're just going to have to keep doing it until it's not weird anymore."
That was when Dipper noticed he was feeling too much warm skin, and realized that Mabel had also shed her nightgown, and, his hand sliding up her thigh confirmed, her panties as well. "That... that makes sense, actually," he said, scarcely able to believe he wasn't dreaming.
She kissed him on the lips and he found himself kissing back, opening his mouth to feel her tongue again.
Yeah, he could definitely see himself getting used to this.
Stan's voice suddenly boomed out and made them flinch and briefly, separate. "Oh my god, what the hell?" he yelled. "That is so disgusting! What the hell did I just step in?" They realized then that he was downstairs, probably on the main floor. "I can't see it, but it smells like shit!" The twins grinned at each other and went back to kissing.
