Chapter 7: The Mabel Sandwich
As far as Mabel was concerned, it had been another perfect day at work. She’d helped Soos fix a clogged toilet (“Never flush a bobblehead,” the man had told her sagely); she and Dipper had sneaked off into the woods to fuck during their break, enabling Mabel to mentally check off another box on her vagenda; and Walt and Retta had paid another visit to the Shack, coming on their bikes this time so that they could hang out for a while instead of being dragged away by their parents. After Mabel confided in them that there was a mysterious bottomless pit in the woods, the kids begged Mabel and Dipper to take them there, and the twins had fun showing the kids that a pinecone thrown in the pit came right back out. (“Even though,” Dipper explained, “for the pinecone, twenty-two minutes have passed.” “Not counting commercials,” Mabel added, making Dipper raise an eyebrow.)
As the end of the work day neared, Dipper approached Mabel, who was sweeping the front porch.
“So,” he said. “I know you’ve got a lot of your own stuff going on, but if you’ve got time after we close, I could really use some more of your help figuring out who took those artifacts and why they left that coded…whatever it is.”
“Really?” Mabel replied, pausing her sweeping. “I mean, not that it isn’t fun sometimes, but solving weird mysteries has always been more up your alley than mine.”
“Actually,” Dipper said, “I don’t think that’s true. Maybe I’m more interested in that stuff than you are, but I don’t think I’m actually better at it. I never would have figured out what all those alien artifacts were for without your help. Just like I never would have found President Trembley without your help. You have a different way of looking at things, and sometimes it’s the only way that works.”
Mabel gazed upward in thought. “Yeah, I guess that’s true.”
“Which is why,” Dipper went on, “I still think of us as the Mystery Twins. Because we’re smarter together than we are on our own.”
Mabel nodded. “You know, someone wise told me something a lot like that recently. Okay, I’m in.”
“Great!”
As soon as the shack closed, Mabel and Dipper went up to their room. Dipper opened his bottom dresser drawer and got out the rolled-up piece of paper they had found with the cache of alien artifacts. He laid it on his bed, and they both gazed at the odd arrangement of symbols on it.
“Unless this is a really abstract kind of code, I don’t think it’s a message,” Dipper said. “My best guess is that it’s a map. Maybe a map to something.”
Mabel picked up the piece of paper with its clusters of odd symbols, turned it ninety degrees, and looked at it intently. Then, from her own dresser, she grabbed one of the tourist maps that the Gravity Falls Chamber of Commerce had put out the previous year, before budget cuts had forced them to stop printing the maps on new paper and instead use recycled placemats from Yumberjacks. These days, hapless tourists scanning the map for the town square sometimes found only the Jumbo Yumbo Burger with Cheese.
“I don’t exactly see a resemblance,” Mabel said, looking back and forth between the two sheets of paper. “Except…”
She leaned down closer to the two maps. “See how there’s this big space where downtown is? And this little space where the Mystery Shack is, and this one where the diner is?”
“You’re right,” Dipper breathed. “It’s like the map is in reverse: All the landmarks are unmarked. The question is, what do the actual marked parts mean?”
“Maybe whoever made this map had their own idea of what a landmark is.”
Dipper looked back and forth between the two maps, then stabbed a finger at one symbol on the mystery map, which looked like a very wide X and was the only one of its kind on the map.
“Isn’t this that abandoned church in the woods?” he asked.
“Where that flying dinosaur thing took Waddles?” Mabel replied. “Yeah, that looks like it. You think X marks the spot?”
“Gosh, could it be that simple? But as far as I can tell, this X is the only thing on the map that corresponds to a real place. So I guess we should check it out.”
Mabel had mixed feelings. She had indeed been planning to go into the woods after work, but that was because she wanted to visit Dee and tell her about the incredible success of Mabel’s threesome with Dipper and Wendy. But Mabel and Dipper had the next day off, so Mabel supposed she could go see Dee then.
“To the abandoned church!” Mabel cried. Then she looked at the Shack’s front steps, which were covered in dirt from the overpriced hiking boots of tourists, and picked up her broom. “Right after I finish sweeping. These steps are gnarly.”
***
The old church wasn’t close by, so Mabel borrowed the golf cart to drive there. Soon, she and Dipper were inside the building, looking down through the gaping hole in the floor into the cavern below.
“Well,” Dipper said, “I remembered to bring the magnet gun this time, but it’s not going to help us get down there.” Then he unslung his pack, and said, “But I brought some rope and a couple of-”
“Grappling hook!” Mabel shouted, quick-drawing the device from her purse and firing the hook up at one of the rafters directly above the hole. The hook caught it and held fast.
“Mabel,” the startled Dipper said, “you don’t have to call it out like it’s a superpower.”
“Says you,” Mabel replied. Then she put one arm around Dipper and held onto him tightly. “Now let’s go!”
They swung gently out over the hole, and Mabel lowered them to the rocky floor of the cavern beneath the church. The twins turned on their flashlights and panned them around.
“These caverns are huge,” Dipper said. “It could take weeks before we find-”
“There it is!” Mabel shouted.
She pointed to a stalagmite near one of the cave walls. The light of Mabel’s flashlight revealed that part of it was shiny metal, which made it rather eye-catching.
The twins walked over to the stalagmite and saw that its exterior had worn away in one spot to reveal a flat surface of what looked like stainless steel. Dipper touched the damp edges of the hole around the metal.
“This isn’t rock,” he said, pulling off a piece of it with his fingers. “It’s plaster or something. Water dripping down from the ceiling must have worn it away over the years.”
“But what’s this metal thingy inside it?” Mabel asked.
“Only one way to find out,” Dipper replied.
He unslung his backpack and pulled out a rock hammer. And even though Dipper showed what Mabel considered to be excessive caution in chipping away the plaster around the metal, it only took him a couple of minutes to completely reveal the object inside the fake stalagmite: a long, slim box with a latch. Dipper put the box on the floor and opened it.
“Another rolled-up paper thingy!” Mabel cried, yanking it out of the box and unrolling it. Dipper held up his flashlight to illuminate the paper, which showed a scattering of strange symbols like the first one.
“It’s another map!” he exclaimed.
“But it’s on a different kind of paper,” Mabel said. Putting her flashlight under it, she added, “It’s kind of see-through-y.”
“I don’t get it,” Dipper said. “Why make a map that just leads to another map? It’s not like this is some kind of birthday-party treasure hunt.”
“I don’t know,” Mabel replied. “But does X mark the spot again?”
“Hmm, I don’t see an X on this map.”
“Well, we’ll have to figure it out later,” Mabel said. “Grandma Soos is making chili dogs tonight!”
***
The next morning, Mabel woke up earlier than usual. This was a bit surprising—not only because she had planned to sleep late on her day off but also because she and Dipper had been fucking and sixty-nining until late the previous night. They were hoping to sharpen up their oral-sex skills before their planned secret liaison with Wendy that weekend.
Having nothing to do until breakfast, Mabel quietly got dressed as Dipper snoozed. Then she slipped downstairs and off into the woods to see Dee.
***
“Mabel,” Dee said after they greeted each other in the clearing, “I’ve got a little surprise for you. And I mean ‘little’ rather literally.”
“Okaaaay,” Mabel replied.
“Because of your many new sexual experiences,” Dee said, “I now have the power to do this.”
As Mabel looked at Dee’s three-foot-tall booby-lady statue, it instantly shrank into a statuette that was perhaps four inches high.
“You’re fun-size!” Mabel exclaimed.
“Exactly!” Dee replied. “Which means that if you like, you can take me home with you instead of having to come out here to see me.”
Mabel picked up the statuette and found that it weighed no more than a bottle of Sir Syrup. She held the stone figure up like a trophy.
“And the Dee Award for Best Sex Scene goes to…!” Dee and Mabel both laughed.
“Seriously, though,” Mabel said, putting the stone figurine down on a flat rock, “this is great. I could even carry you around in my purse!”
“Indeed,” Dee said. “Then you could consult with me whenever you wish. And you could rub my boobs for luck.”
“Really? Your boobs are lucky?”
Dee chuckled. “No, not really.”
Mabel giggled. “I’m gonna rub ‘em for luck anyway.”
“I thought you might. Now, on to today’s new vagenda item.”
“Ooooh, what’ve you got in your sick little mind now?” Mabel asked, rubbing her hands together and looking gleefully at the statuette.
“Well,” Dee said, “now that Dipper has gotten to experience sex with more than one girl at once, I think you deserve a chance to try sex with more than one boy at once.”
“Wow,” Mabel said. “That sounds like a great idea. But I’m not sure what I would do with more than one boy.”
“Well,” Dee said patiently, “you like getting fucked in your pussy, don’t you?”
“Sure I do!”
“And you like getting fucked in your ass, yes?”
“Definitely!”
“Then wouldn’t you like to try both at once?”
Mabel’s eyes went huge.
“Really?” she gasped. “That’s a thing?”
“Oh, indeed it is. And I think it’s a thing you should try, don’t you?”
“Oh heck yeah!” Mabel replied, shaking her fists excitedly. Then her brow furrowed. “But I’m not sure if Dipper would want to get it on with another dude.”
“We’ll get him to try it one of these days. But for this particular act, it’s not strictly necessary that the ‘dudes’ get it on with each other. It’s also not strictly necessary that Dipper be one of them. Remember, Mabel, this sexual journey you’re on is as much about empowering yourself as it is about your destiny with your brother.”
“Yeah,” Mabel replied, “but if I’m going to have two dicks in me at the same time, it would be nice if I already knew one of them.”
“Fair enough. And speaking of fairness, Dipper owes you for arranging the threesome with Wendy. If he objects to being a slice of bread in your hot Mabel sandwich, you might remind him of that.” Mabel nodded.
“Now,” Dee continued, “the question is, who should the second boy be? Is there anyone you’ve had your eye on? And don’t tell me you’ve been thinking only of Dipper; human beings wouldn’t have eyes if they weren’t meant to wander now and then.”
“Well,” Mabel said, “that boy Darren from the hobby store is pretty cute.”
“Oh, he is indeed,” Dee replied.
“And he and Dipper have been hanging out a little, so they’re already buds!”
“And on top of that, I’m fairly certain he’s been checking out your boobs whenever you go into the hobby store. Your ass, too.”
“Wow,” Mabel replied. “I never even noticed.”
“He’s good at playing things close to the vest, which is another item in the plus column. Wendy being older than you deters her from telling others about her little liaison with you and Dipper, but a boy your own age might be considerably more…talkative, with his peers. Best to choose a boy with discretion.”
“But how do you know that Darren’s got…dispression, or whatever? Or what he looks like?” Mabel asked. Then she gasped. “Wait, do you watch me all the time, like Santa?” She chuckled nervously and added, “I mean, not that I still believe in Santa Claus, because obviously I’m way too mature for that. Although now that I think about it…If gnomes are real, and unicorns are real, and reduced-fat pork rinds are real, does that mean-”
“I honestly don’t know, Mabel,” Dee interrupted. “While I do see many things, I’m afraid my perception does not extend as far as the North Pole.
“Now, with regard to Darren, I think few seductive words from you will be sufficient to get him into your bed.”
“Even if Dipper is also in my bed? I mean, not literally my bed, because it barely fits two of us. But wherever we do it, I’m not sure boys are that into, you know, sharing.”
“Mabel, my dear, you still have a few things to learn about young teenage boys. I’m sure Darren would be happy to share you with a jealous pit bull if it meant getting to put his perpetually erect teenage cock into any of your holes.”
“Wow,” Mabel said. “This sounds like a ‘hole’ lot of fun!”
“Yes, do avoid using puns during your threesome,” Dee replied dryly. “Or during any sexual activity with persons who understand English, for that matter.”
“Pbbblt!” Mabel replied. “You may be wise and everything, but you’ve got no sense of humor.”
Dee sighed, then said, “Now, let’s discuss how you’re going to engineer this little get-together…”
***
That night, after everyone had gone to bed and Mabel and Dipper had enjoyed a prolonged, multiorgasmic sixty-nine, the twins lay together in Dipper’s bed. It amused Mabel to think that Dee, now in Mabel’s purse, had heard everything.
“So Dipper,” she said, “how would you feel about having another threesome? But with two boys this time?”
“Wow,” Dipper said, looking at Mabel askance. “I mean, what kind of…stuff…would you want to do?”
“Don’t worry, I don’t wanna watch you suck the other boy’s dick or anything. Okay, that’s not true, ‘cause I kinda do wanna see that, but that’s not what I want to do this time.”
“Okay, tabling that long conversation for later,” Dipper replied with a half-frown. “So what are you looking to do?”
Mabel smiled at him. “Have two dicks in me at the same time. I mean, in two different holes, not the same hole, ‘cause I’m not ready for that.” She got a naughty look in her eye as she added, “Yet.”
“Well, fair enough, I guess,” Dipper replied. “And it would be kind of interesting to find out what it’s like to fuck your pussy when there’s someone else fucking your ass, or vice versa.”
“Exactly!” Mabel said, grinning at hearing Dipper say words he never would have used in front of her mere weeks ago. “And I know just the guy to provide that second dick: Darren!”
Dipper looked surprised. But not in a bad way.
“I guess,” he said, “if I was going to choose any guy in Gravity Falls to be, you know, at the other end of you, I’d probably pick him. I mean, he’s a good guy, and I think he’s kinda into you. I’ve actually been a little worried that he was going to ask me about asking you out, because I don’t know what to tell him. I mean, I can’t just say, ‘Sorry, I’ve got dibs on my sister.’ And I didn’t want to have to make up a lie and then force you to tell him the same lie.”
“Which is nice of you, but you don’t need to worry, ‘cause we’re gonna have to let him in on our little secret for this threesome to work. I mean, unless we do it with costumes and masks and stuff, but I kinda want to check that box later.”
“Check what box, now?”
It occurred to Mabel that she hadn’t actually told Dipper about her vagenda, let alone about her conversations in the woods with Dee. But everything had been going so great that she’d hesitated to expose Dee to Dipper’s implacable need to understand everything and risk ruining it all.
“Oh, um, I just mean that I don’t want to try boy-boy-girl and sex-cosplay at the same time. I’d rather give each of those things its own time slot, you know?”
“Um, sure, okay. So, when do you want to do this?”
“Well, let’s see what Darren’s doing tonight.”
***
Mabel thought about calling Darren, but she wasn’t sure how well her newfound powers of seduction would work over the phone. So she and Dipper went to Hobby Horse to approach him in person. Mabel made sure to wear her shortest skirt and tightest sweater.
“Hey, guys!” Darren called, coming out from behind the register. “You here for supplies, or just dropping by to say hi to-” he smiled at Mabel “-your favorite glitter dealer?”
“This is purely a social visit,” Mabel replied. “We came to see if you want to hang out with us tonight.” She lowered her voice as she added, “We know this cool little spot in the woods where we can do…anything we want.”
Up to that point, Mabel’s tone had been more or less conversational, but those last three words she infused with a good dose of sultriness. So Mabel was pleased to hear Darren—who was generally easygoing and not easily rattled—suddenly develop a bit of a stutter as he replied, “That sounds g- great!”
“Cool,” Dipper said.
“See you tonight at eight,” Mabel added.
“Y- Yeah,” Darren stammered. “See you then.”
Mabel and Dipper turned around to head for the door when Mabel spied half of a blonde head peeking out from the end of one of the aisles. It quickly disappeared, so Mabel hurried to that aisle and found Pacifica there, intently browsing the shelves.
“Hey, Pacifica!” Mabel said, making the girl jump a bit. “How’s things? I didn’t know you were into crafts. And especially not-” she narrowed her eyes as she looked at the shelf Pacifica had been staring at “-paint by numbers?”
“Oh, yeah, well,” Pacifica replied, “I have to make a lot of my own stuff these days, so if I want any art on my walls, then, you know.”
“Oh, sure, I make a lot of my own stuff, too,” Mabel replied. “Have I showed you my electric rainbow sweater? No, I probably haven’t, since I have to be close to an outlet to wear it. But maybe you could come over some time and see it. Especially now that I know where Soos keeps the fifty-foot extension cords. And also how to change a blown fuse.”
“Um, yeah, that, that sounds cool,” Pacifica replied.
***
After dinnertime that night, Darren met Mabel and Dipper at the Shack, after which the three of them headed out for what Mabel described to Soos as a walk in the woods.
“It’s eat or be eaten out there, dudes,” Soos replied. “So take some cookies!”
He pointed to a sheet of sugar cookies that Grandma Soos had just baked. Mabel put some in a plastic zipper bag and placed it in her big beach bag, which also contained a picnic blanket and, at the bottom, a tube of lube and Fun-Size Dee. Then she, Dipper, and Darren headed out into the forest, making small talk as they went.
Mabel didn’t take them to the clearing by the cave; that was a bit of a hike—literally—and Mabel didn’t want Dipper asking questions about the cave and how she’d found it when there was important double-penetrating to do. Instead, Mabel simply led the boys to the spot about fifty yards into the trees to which she and Dipper had recently slipped away to fuck during their work break. The spot was well hidden, which was important; at this northern latitude, the summer sun didn’t set until almost nine o’clock, so it was still broad daylight.
She took the blanket out of her beach bag and spread it on the ground. Now, it was time to get seducing.
“So Darren,” Mabel said with a touch of sultriness, “can I ask your opinion about something?”
“Um, sure, yeah,” the boy replied.
Mabel peeled off her sweater—and her top right along with it, revealing a white cotton bra with gold-lamé trim.
“What do you think of this?” Mabel asked sweetly. “I just finished decorating it this morning.”
“Wow,” Darren said, wide-eyed. “That’s, that’s good craftsmanship.”
“I was hoping you’d think so,” Mabel replied. “Now, how about you give me your opinion on these?”
She undid the bra’s clasp and pulled the cups away to show Darren her bare breasts. The boy’s jaw literally dropped.
“You’re really cute, Darren,” the topless Mabel said, drawing close to him. “Wanna kiss me?”
“I- I-” the boy stammered.
Mabel had figured that unlike Wendy, Darren probably had little experience getting intimate with girls and zero experience with sex, so Mabel would have to do the heavy lifting here. So she leaned forward and kissed him. Soon, he started kissing her in return, and once the kissing evolved into serious making out, Mabel took Darren’s hands and put them on her boobs. He immediately started fondling them, making Mabel kiss him even more passionately—and unbutton Darren’s shirt.
Per their plan, Dipper had so far just been standing back and observing. Now, he came up behind Mabel, reached around her, and undid the button on the front of her skirt. After the skirt fell to the ground, Dipper began caressing Mabel’s ass through her cotton undies, which Mabel had also trimmed with gold-lamé.
Mabel had just stopped kissing Darren to take a breath. Now, Darren looked down at Mabel’s fallen skirt, then panned partway up to her exposed and rather damp panties, then at Dipper’s hands on Mabel’s ass, and finally back to the girl’s face.
“W- Wow,” he stammered.
“I know,” Mabel said, “it’s kinda crazy. But I’d really like to play with both you guys, if that’s okay with you.”
It seemed that words had failed Darren entirely. But that didn’t stop him from nodding vigorously.
“Awesome,” Mabel said. “Let’s all get naked and have some fun.”
Darren may not have been able to speak, but he certainly didn’t have any trouble shrugging off his unbuttoned shirt, then dropping his jeans onto the blanket and, finally, pulling down his boxers to set his very hard cock free.
They say some guys’ mouths write checks their bodies can’t cash, Mabel thought as she grinned at the sight of Darren’s erection. But I guess some other guys are the opposite.
“Nice,” Mabel said. Then she put her hands on Darren’s shoulders and murmured, “Lie down.”
Darren sat down on the blanket and lay back, and Mabel lay down on top of him. His nicely toned chest was hot against her breasts.
“Ready?” she said.
Darren nodded even more vigorously this time. So Mabel got up on her knees and straddled him.
“Hold it up for me,” she murmured, “so I can put it inside.”
Darren grabbed his cock by the base and held it upright. He was almost panting with excitement as he looked up at Mabel. She grinned at him and positioned her pussy such that her lower lips were kissing his cockhead.
“Here we go!” she said.
She lowered herself down, and both she and Darren moaned as she took him inside her to the balls. Then she leaned forward, putting her face right above his, and began to move slowly forward and back. Darren closed his eyes and moaned softly.
It’s amazing, Mabel thought, watching a boy fuck for the first time. I think I want to give more boys their first times.
Mabel wasn’t worried about riding Darren—or Dipper, for that matter—bareback. Even though Mabel wasn’t using the chocolate anymore, Dee was now strong enough to make all sex safe for Mabel. (“Until you don’t want it to be,” she’d added saucily.) So she was looking forward to feeling Darren cum inside her. But there were other pleasures to be enjoyed first—as Dipper reminded her when he knelt down behind her and put his lube-slicked cockhead against her little pink asshole. Mabel bit her lip in anticipation.
Dipper pushed in. Mabel took a deep, gasping breath as Dipper’s cock eased into her ass, its underside pressing against that of Darren’s cock through the thin wall of flesh between Mabel’s two channels. She could feel every bit of movement through that wall, and it was deliriously pleasurable.
“Oh God…” she gasped. “Oh God it feels so good…”
Once Dipper was all the way in, Mabel held still, taking a moment to fully appreciate the feeling of being so filled up. Then she started to move slowly forward and back.
“Oh yeah…oh yeah…oh yeah…” she breathed in time with her movements. She felt the boys begin to move with her, helping her get their cocks father into her on every stroke.
She wanted it to last forever. But in reality, she could only keep up that pace for a couple of minutes, because then she needed more: harder, faster, deeper. So she started moving a little more vigorously.
“Oh yeah,” Dipper moaned as he increased his pace to match Mabel’s. “So nice…and tight…”
“Oh h- heck yes,” Darren gasped.
Over the next minute, the pace of the fucking continued to increase. Mabel gasped and moaned nonstop as the boys’ cocks went from pumping her holes to pounding them. Her little breasts jiggled wildly above Darren’s chest as she worked her body hard against the boys’, making sure they went in balls-deep on every powerful stroke.
“Ohmigosh…” Mabel panted. “I’m so close…I’m gonna…gonna…AAAAAAAAH!”
Mabel came hard, and when she felt both of her holes squeeze tight around those shafts of male flesh inside her, she came harder still. Both boys shouted, and Mabel felt their hot semen shooting deep into her body, and then she shrieked and thrashed as her orgasm reached an even higher plateau.
“Oh wow,” Mabel panted as she came down from her massive climax. “Oh, wow, your cocks…so good…so good…”
“I’m glad…you liked it…” Dipper panted in reply. Then, after taking a moment to get his breath back, he went on, “Because I don’t think we’re anywhere near finished with you. Are we, Darren?” he asked, looking across Mabel’s back at his friend.
“N- No,” Darren replied. “Definitely not finished.”
“Which of her holes do you want to try next?” Dipper asked, handing Darren a couple of wipes from a packet before using a couple more on his own cock.
Mabel thought she ought to be offended by the way Dipper was talking about her—as though he owned her, and the use of her holes was his to offer. But at the same time, there was something pretty hot about it. She would definitely need to explore that later.
“Yeah,” Mabel added, raising her head to look at Darren’s face and giving him a goofy smile. “Take your pick.”
“I- I wanna try your ass,” Darren replied eagerly.
Mabel looked back over her shoulder at her brother. “How ‘bout you, Dipper?”
Dipper smiled at her, then at Darren. “How about we do her from both ends? You take her ass, I’ll take her mouth.”
“Awesome,” Darren replied.
“Works for me!” Mabel cheered.
Darren slid out from under her, and when Mabel sat up, both boys were standing on either side of her. It occurred to Mabel that this was a very different kind of threesome than the one she’d had with Dipper and Wendy. In that situation, each participant had more or less been equally interested in sex with the other two, but here, her two partners were solely interested in Mabel rather than each other. This made her the center of attention, which was awesome. But it also made her chiefly responsible for pleasing both Darren and Dipper, which put her under a certain amount of pressure: If both boys didn’t have a good time, then they wouldn’t want to do this again. And Mabel really wanted them to want to do this again.
So Mabel took a half-erect cock in each hand and began massaging them simultaneously. Both cocks were coated in cum, making it easy for Mabel to slide her hands up and down their lengths. And while she did it, each boy fondled one of her little tits, which was getting Mabel good and aroused again.
“It sure is fun having two handfuls of dick,” Mabel said, smiling up at them.
Darren grinned at her goofily and replied, “One handful of boob is n- nice, too.”
It didn’t take Mabel long to get both cocks back to full mast. Which she was glad of, because she needed those dicks inside her again.
“Okay, boys,” she said, getting down on all fours. “Time to give it to me from both ends.”
Dipper knelt in front of her, standing up on his knees to put his cock at the same height as her mouth. Darren went behind Mabel and took up a similar position to Dipper’s. Mabel looked back at him and smiled.
“Ready?” she asked sultrily.
“Oh yeah,” the boy panted.
He put his cockhead against her pink asshole, and Mabel felt him make little adjustments until it was perfectly centered. Obviously, Darren wanted to make sure he did everything right on his first ass-fuck.
“Mmm, push it in,” Mabel breathed.
Darren pushed, and Mabel gasped at the sensation of his cock filling up her ass. Even though she’d just had Dipper’s cock in there, Darren’s cock had a bit more curve to it, which made it feel different when Darren pushed it in to the balls.
“Mmmm,” Mabel hummed. “Feels like we’re good to go.”
She looked up at Dipper’s face and opened her mouth. The boy pushed his cockhead just past her lips, letting her suckle it while Darren started pushing slowly in and out of her ass. She could tell that the handsome hobby-store clerk wanted to savor his first-ever assfuck.
“Ohhh, Mabel…” Darren sighed. “Your ass feels as g- good on the inside as it looks on the outside…”
“Mmm-hmm-hmm,” Mabel replied—the closest she could get to “Why, thank you” with a cock in her mouth.
Soon, Mabel started moving forward and back in time with Darren, which helped her ensure that he got all the way into her ass on every stroke while also enabling her to massage much of Dipper’s cocklength with her lips. Dipper got the idea and moved in time with Mabel, too, thus gently fucking her mouth.
The three were so in sync that when they began to move a little faster, Mabel couldn’t tell whether it had been one of the boys or she herself who had started it. But she welcomed it either way, because she needed those cocks to pump her harder. And then Dipper’s hands went to the sides of her head, and Darren tightened his grip on her ass.
I think this is about to become Miss Mabel’s Wild Double-Dick Ride, she thought. Yee-haw!
Darren started pumping Mabel’s ass good and hard, and Dipper fucked Mabel’s face just as vigorously. Mabel pushed her body back and forth as fast as she could, but she soon found that she couldn’t keep up, so she just let the boys take the reins and pound her. She swallowed periodically to keep from gagging when Dipper’s cock would hit the back of her throat, and she had the fleeting thought that one of these days she wanted to try that “deep-throat” trick Dee had told her about. She bet that would blow Dipper’s mind. And Darren’s mind. And the mind of any other boy she chose to fool around with. Because even as the boys fucked her like crazy, it was just now dawning on Mabel that she could indeed have sex with any boy—or girl—she chose. Which turned her on even more.
“M- Mabel,” Darren gasped. “I’m…gonna…shoot…soon…”
“Ymm! YMM!” Mabel cried eagerly, needing to feel Darren’s hot load deep in her ass.
“Aaaaaah!” Darren shouted, gripping Mabel’s ass tightly. Indeed, when Mabel felt his hot cum jet into her bowels, she screamed “MMMMMMM!” and—without even trying to—swallowed Dipper’s cock down her throat. Dipped shouted “OH MY GOD!” and immediately fired a torrent of seed straight down into Mabel’s stomach. She swallowed again and again as she continued to convulse with orgasm, something deep within her wanting every drop of her brother’s cum.
Mabel released Dipper from her mouth, and the three teens collapsed onto the blanket, gasping.
“That was…incredible,” Darren panted.
“So incredible,” Dipper managed.
“You two…are fun…to play with…” Mabel puffed.
They took a minute to get their breath back before any of them spoke again.
“I can’t believe I just had sex for the first time,” Darren said. “In, like, the weirdest way possible. But it was awesome.”
“It sure was,” Mabel replied. “Hey, you’re not stuttering anymore.”
“I used to do it all the time,” Darren said, “but speech therapy helped. Now it only happens when I’m, you know, hyped up emotionally.”
