Chapter 9: Breaking and Entering
“Okay, so,” Dipper said as he and Mabel were walking back to the Mystery Shack from Greasy’s Diner, “it was kind of obvious that Pacifica was lying about not finding that secret compartment, right?”
“Totally obvious,” Mabel replied. “Which is weird, isn’t it? I mean, Pacifica must be good at keeping a secret, ‘cause it seems like most people don’t know she’s been boinking for money.”
Dipper raised an eyebrow. “But I guess you figured it out.”
Having in fact been clueless about Pacifica’s second job until Dee told her about it, Mabel replied, “Um, oh, yeah, I did. But it’s not like everybody in town is talking about it, so Pacifica must be a pretty decent liar.”
“Good point,” Dipper replied. “Maybe she’s off her game today.”
Mabel nodded. “When we came into the diner, before she even saw us, she had this look like something was bothering her.”
“The question is,” Dipper said, “what do we do now? It’s not like we can tie her to a chair and interrogate her.” Ignoring Mabel’s snigger, Dipper went on, “And we can’t break into her house and search the place. I mean, we could, but I feel like that wouldn’t end well.”
“Hmm,” Mabel said with a frown. Then an idea struck, and she pointed a finger at Dipper. “Maybe we don’t have to break in.”
“What are you talking about?” Dipper asked.
“You could pay her to have sex with you! Then she’d let you into her house. And other places,” she finished with a snicker.
Dipper just sat there for a moment, apparently processing this idea. Then, slowly, he nodded.
“And while I’m keeping Pacifica busy,” he said, “you could sneak around and look for the mystery item.”
And, Mabel thought, this could be a perfect way to check my voyeurism box!
“But,” Mabel said, “how am I going to find it if I don’t know for sure what it is?”
“Well, even if it’s not another map, it probably doesn’t look like anything else Pacifica owns.”
Mabel brightened at that. Putting a hand on her hip, she said, “Right! I’ll be solving this mystery with my keen sense of style.”
“Um, sure,” Dipper answered. Then, perhaps humbled by the memory of Mabel’s success with the alien gadgets, he added, “I mean, it’s worked before.”
***
Mabel and Dipper agreed that Dipper needed to approach Pacifica by himself, figuring that most guys probably didn’t bring their sister along when they were soliciting sex from a prostitute. So after work the next day, Mabel busied herself with knitting a sling-bikini undergarment while Dipper went to see Pacifica at the diner.
Dipper arrived back at the shack just a few minutes before Grandma Soos’ designated dinner hour, so the twins ran up to their room, and Dipper told Mabel about his conversation with Pacifica.
“She didn’t seem all that surprised that I knew she was having sex for money,” Dipper said. “But she did seem a little surprised that I wanted to hire her. Especially after she told me her prices. She charges seventy-five dollars for a blowjob, a hundred for a fuck, and a hundred and fifty for a half-and-half.”
“Um, we’re not talking about dairy products here, right?” Mabel asked.
“It means a blowjob and then a fuck,” Dipper replied. “Don’t worry, I had to ask, too.”
“So what did you end up ordering—if ‘ordering’ is the right word?” Mabel asked.
“I asked for the half-and-half,” Dipper replied. “I know it’s a lot of money, but I figured that was our best chance of getting her to take me to her house instead of just doing it behind the diner. And she actually did suggest that we go to her house, without my even asking her. She didn’t offer me a ‘friend discount’ though—she said she was going to give me something better than a discount—and I’ve only got about ninety dollars saved up, so…”
“Don’t worry, bro, I’ll pitch in,” Mabel replied, even as she mentally bid farewell to that penguin sweater she’d been saving up for. Somehow, solving this mystery seemed important, and not just because Dipper was so invested in it. Plus, Mabel figured, she would never have a better opportunity to check that voyeurism box on her vagenda.
***
After sundown that night, Dipper walked up to the front door of a rental house on the outskirts of town. The house looked pretty run down, but it still looked better than the two homes that neighbored it: a trailer home that was up on cinder blocks, and a shipping container with a couple of windows cut in the side.
“Wow,” Dipper said, “this neighborhood is…not great.”
“Yeah,” Mabel replied, “but at least they’re making an effort.” Pointing at a window box on the side of the shipping container, she added, “Those daisies set off the corrugated metal nicely.”
Staying out of the circle of light provided by the block’s one working streetlight, they went over to a tree that was across the street and slightly uphill from the house. Then Dipper unslung his backpack and took out what looked like a big pair of goggles with headphones attached.
“This is Great Uncle Ford’s surveillance headset,” he said, handing the device to Mabel. “Once you’re up in the tree and turn this on, you should be able to see and hear everything that happens inside the house.”
“Sweet,” Mabel replied. She put the apparatus on her head, then pointed at herself with her thumbs and said, “Mabel Pines, super-spy.”
Mabel climbed up to a thick branch about eight feet from the ground. Then she put her back against the trunk of the tree and let her legs dangle on either side of the branch.
Wow, that was easy, she thought. I think all the sex is getting me in better shape.
“We should test the headset,” Dipper whispered up to her. “Turn it on and tell me what you can see.”
She switched on the headset, and immediately, her vision zoomed in on what she was looking at—in this case, her brother’s crotch.
“I can see you’ve got a semi-boner going,” she whispered back. “And there I thought you were just doing this to distract Pacifica; I didn’t know you were actually horny for her. I mean, I get it, she’s hot, but I didn’t think a girl who bangs truckers behind the diner would be your-”
“Okay, test successful,” Dipper cut in. “Let’s try the headphones now.”
He backed away about twenty feet and whispered, “Can you hear me?”
“Wow, it’s like you’re right in front of me,” Mabel whispered back. Then, remembering that she was the only one wearing headphones, she gave Dipper a thumbs-up.
“All right,” Dipper whispered, “I’m going in.”
Mabel flashed him her boobs for luck, making Dipper grin. Then he headed down to Pacifica’s front door and knocked.
After a moment, Mabel saw lights come on downstairs. Then, through the three downstairs windows that faced Mabel, she saw Pacifica come to the door and look through the peephole.
“Hey, Dipper,” she said as she opened the door. A bit sultrily, she added, “Come on in.”
“Hey, Pacifica,” the boy replied as he entered.
Mabel couldn’t help but be impressed with Dipper’s skill. As he entered the house behind Pacifica, he casually gripped the edge of the door and pulled it closed behind him—transferring a loop of clear packing tape from his finger to the door’s latch bolt in the process. This way, the door would shut, but the lock would not engage.
“Thanks for being willing to do this at your house,” Dipper said to Pacifica; with the headphones, Mabel could hear him pretty well, even through the wall of the house. Then Dipper glanced around and asked. “Your parents aren’t here, right?
“No,” Pacifica said. “They’re out of town most of the time. They spent all the rest of our money on their new startup company before they discovered that they didn’t have enough to actually, you know, start up. So now they go around the country pitching their business to rich investors. Most of those people used to be my parents’ friends, which just makes it extra-awkward for everyone when they say no.
“Anyway,” Pacifica continued, “I don’t usually bring clients here; I just blow them in their truck cabs, or let them fuck me against the wall behind the diner. But I know you, and I trust you.” She sighed and added, “Which is not something I can say about a lot of people these days.”
Mabel could see the flash of guilt on Dipper’s face, and she felt a pang of it herself, too; Pacifica trusted them, and here they were spying on her. But Mabel reminded herself of the importance of her mission.
“I guess things have been pretty tough for you,” Dipper said.
“Yeah, kinda,” Pacifica replied. “And not being rich anymore isn’t even the bad part. The bad part is all my so-called friends—girls I’ve known since we were little kids on ponies at riding camp—suddenly acting like I don’t exist. Which means that I have no friends, because all the kids at Gravity Falls Middle School hate me, even though they don’t even know me.”
She sighed. “Not that I blame them. When I look at the person I used to be, the way I used to treat people…I think I’m better off being a diner waitress and a part-time whore.”
Then she looked up at Dipper, and her face brightened. “But enough about all that. I brought you here to have fun.” Her voice turned sultry as she went on, “As a matter of fact, I’m not just going to let you fuck me in my house; I’m going to take you upstairs and let you fuck me in my bed.”
From the look on Dipper’s face, Mabel could tell that her brother was thinking with the little head and not the big one as he replied, “Um, yeah, that, that sounds great!”
Uh-oh, Mabel thought. It would be tricky to search Pacifica’s room if the blonde girl and Dipper were in there boffing away. On the other hand, Pacifica and Dipper going upstairs would enable Mabel to search the entire downstairs without risk of being caught. And if Mabel did end up having to go upstairs, at least she would be able to search for the mystery item and check the voyeurism box on her vagenda at the same time.
So as soon as Pacifica led Dipper up the stairs, Mabel climbed down from the tree, took off the spy headset, and stuffed it into Dipper’s backpack before putting the backpack on. (Dipper had insisted that Mabel leave her own backpack at home, saying that its rainbow colors and cartoon kittens would not make for good camouflage.) Then Mabel approached the house, slipped in through the front door, and took off her shoes for the sake of stealth.
She thought about where she would hide something if she had to do it in a shared space like the living room/dining room/kitchen that made up most of the first floor. So she checked the undersides of the living room’s single easy chair and sofa, looked in the back of the largely empty pantry, and peered under one loose floorboard. Mabel wasn’t sure who was more startled—her, or the possum whose nest she uncovered and then quickly covered again.
The floorboard was close to the base of the stairs, so Mabel could overhear the conversation on the second floor, even without the headset.
“So Dipper,” Pacifica was saying, “do you like baseball?”
“Um, not especially,” the boy answered. “Why?”
“I thought you’d like to play a little second base.”
There was a pause and a brief flapping of fabric, and then Dipper said, “Okay, I stand corrected.”
Mabel felt a pang of envy, because she wanted to see Pacifica’s boobs, too. They always looked so cute under the blonde girl’s apron at the diner—and positively delicious in that slutty top that Pacifica wore under the apron.
But Mabel consoled herself with the knowledge that she would be seeing Pacifica’s cute little titties and probably her whole naked body pretty soon, because it was becoming increasingly clear that the mystery object wasn’t downstairs. Unless Pacifica had plastered it into the wall or something, but Pacifica had never exactly been the DIY type, paint-by-numbers notwithstanding.
“Ooooh, yeah, squeeze ‘em,” Mabel heard Pacifica say. “Hey, you really know your way around a pair of titties. You must be having a lot of fun with the girls back home.”
“Oh, um, yeah, back home, definitely,” Dipper replied. Then, perhaps anxious to change the subject, he said, “Wanna lose the skirt, too?”
“You know I do. This body is all yours tonight, lover.”
Having searched the last of the cans in the pantry, Mabel checked the floor for more loose boards. She knew she couldn’t safely go upstairs until Dipper and Pacifica had moved on to at least the first half of Dipper’s half-and-half, so she figured she might as well be thorough.
After a couple minutes, during which Mabel imagined Dipper running his hands all over Pacifica’s naked body, Mabel heard Pacifica say, “So, ready to get your dick sucked, big guy?”
“More than ready,” Dipper replied.
Mabel crept to the base of the stairs, then ascended them slowly in a crouch. She had seen through the windows that Pacifica’s bedroom was right at the top of the stairs; therefore, when Mabel approached the top step, she got down on all fours to ensure that her head was not sticking up into Pacifica’s line of sight, should the blonde girl happen to be looking in Mabel’s direction.
Fortunately, Dipper seemed to have thought of that: He had positioned himself on the far side of Pacifica’s bed, looking toward the stairs. Thus, Pacifica was facing the opposite way as she knelt in front of him. Only the top of Pacifica’s blonde head could be seen above the purple bedspread, but Mabel could hear the girl licking Dipper’s cock.
I’ll wait until she puts it in her mouth, Mabel thought. Then she won’t be able to just whip her head around if she hears anything. And the sucking noises might keep her from hearing me at all.
“Remember when I said I’d give you something better than a discount?” Pacifica said to Dipper. “Well, normally, I make the guy wear a condom. But tonight, I’m gonna let you go bareback.” With a seductive smile, she added, “Even when you fuck me.”
“Wow,” Dipper said. “That’s, that’s great.” Then, with a note of concern, he said, “I don’t have any STDs or anything, but what about-?”
“Don’t worry about knocking me up,” Pacifica interrupted. “I keep a stash of Backup Plan pills around in case a condom breaks. I’ll just take one of those later.”
“Awesome,” Dipper replied, his voice going ragged with lust.
Mabel listened intently. After a moment, she heard Dipper moan softly. Then she could hear soft sucking sounds, like Pacifica was slowly moving her lips up and down Dipper’s cock.
“Oh, yeah,” Dipper breathed. “That’s nice…”
Mabel felt a pang of envy—not because Dipper’s cock was in another girl’s mouth, but because Mabel had yet to elicit such a response from Dipper so early in the cocksucking process.
Then again, Mabel thought, Pacifica is a professional. I wonder what she’d charge for lessons?
Mabel crawled into the bedroom and quietly slipped under the bed. All she found there were dust bunnies; she took care not to breathe any in for fear of sneezing.
From this position, Mabel could see the kneeling Pacifica’s bare ass through the bed’s gauzy dust ruffle. Fate may not have been kind to Pacifica, at least not lately, but Mother Nature had certainly done the girl a few favors, including giving her a very cute bubble butt.
Now came the hard part of the search. Mabel had needed to dig deep into her wardrobe to find a sweater whose color was even close to real-estate beige, but now she was glad she had, because she was going to have to crawl across four feet of open floor between the foot of Pacifica’s bed and the white-slatted door of her closet, potentially putting herself at least a little bit in Pacifica’s peripheral vision.
But Dipper, who could see Mabel when she began to emerge from beneath the bed, again managed to think with the big head—or at least with both heads—because he put his hands on Pacifica’s face, on either side of her eyes, and began gently fucking her mouth as he moaned, “Oh, God, I can’t help it…”
Mabel slithered into the closet and closed the door behind her as quickly and quietly as possible. Then she breathed a sigh of relief, because almost immediately after that, she saw Pacifica release Dipper’s cock from her mouth and look up at him.
“If you wanna cum in my mouth,” she said sultrily, “I promise I’ll swallow.”
Mabel felt a bit of pride, because she had swallowed Dipper’s seed on several occasions and knew how much he loved it. So at least her BJs were as good as Pacifica’s in that respect.
“Oh, yeah,” Dipper gasped.
Pacifica put Dipper’s cock back in her mouth, and Dipper again took hold of her head and resumed fucking her face. And while Mabel wanted to watch the action, it seemed possible that this was the best opportunity she was going to have to search the closet without being heard.
There wasn’t a lot of closet to search, which made it pretty easy for Mabel to see that there was some space between the back of the plywood shoe rack and the back wall of the closet. In that gap, she found a treasure trove of items that, apparently, Pacifica was keeping hidden from her parents. Mabel grabbed the first of them, a book, and held it up to read the cover in one of the thin beams of light that came through the door slats.
So You Want to Be a Teenage Prostitute, by…S. Pines?
She turned the book over. On the back cover was a picture of a decades-younger Stanley Pines wearing a zebra-print suit and holding a gold-headed cane.
Wow, Mabel thought. That was not a good look for Grunkle Stan, even in the ‘80s.
With a shudder, Mabel put the book back and pawed through the other items behind the shoe rack. She found a couple of packs of condoms and a bottle Backup Plan pills before she hit pay dirt: a rolled-up sheet of paper that, when Mabel partly unrolled it to peek at the contents, appeared to be a map just like the other two, complete with indecipherable symbols. Mabel then held the paper up to the light and saw that the map was translucent, like the one they’d found in the dinosaur cavern. She rolled the map back up, folded it in half, and put it in Dipper’s backpack.
There was one more item behind the shoe rack, and Mabel had to pick it up before she could see what it was: a little wooden block with a round hole at one end and a smaller, rectangular hole at the other.
An old-timey whistle? Mabel thought. That doesn’t seem very…Pacifica. Remembering the plan to look for anything that didn’t seem like Pacifica’s style, Mabel put the whistle in the backpack with the map.
Now, Mabel was satisfied that she had found everything there was to find. So she turned her full attention to watching Dipper and Pacifica through the slats of the closet door. If she moved all the way to the right, she could kind of see Pacifica’s face, which Dipper was now fucking like mad.
“Oh God, Pacifica!” Dipper shouted. “I’m gonna…I’m…AHHHH!”
Mabel heard Pacifica swallow several times as Dipper shot his load into her mouth. Then, when he was finished, she released his cock from between her lips and looked up at him before swallowing one last time and giving him a big smile.
“Wow,” she said. “Do you always cum that much, or did I really turn you on?”
“Ohmigosh,” Dipper panted, “that was fantastic…”
“Glad you liked it,” Pacifica replied. Then she stood up. “Now, how about we quit letting my perfectly good bed go to waste?”
She lay down on the bed, striking a sexy pose that Mabel thought was like a cross between a Renaissance “reclining nude” pose and something from a mudflap. Dipper gave her a horny-idiot grin and lay down next to her.
“So,” Pacifica said, putting her hand on Dipper’s cock and starting to massage it back to hardness, “how do you want your second half? I know lots of fun positions.”
“Well, uh,” Dipper said, “call me old-fashioned, but I think I’d like to go missionary.”
“Sounds good. Maybe you can fuck some godliness into me.” Dipper chuckled hornily.
The closet faced the foot of the bed, so when Pacifica turned onto her back and opened her pale thighs wide, Mabel had a perfect view of the blonde girl’s pink pussy.
I’ll be darned, Mabel thought. The carpet matches the wallpaper, or however that goes. Although, being a prostitute, maybe she dyes them both?
Dipper got on top of Pacifica, and now all Mabel could see was legs and genitals. But that was okay, because it enabled Mabel to actually watch Dipper push his cock inside Pacifica. Both Dipper and Pacifica moaned as he entered her, and Mabel had to put her hand over her mouth to stifle her own gasp at the sight of her brother starting to pump this hot girl.
Mabel thrust her hand down under her skirt’s waistband and into her panties and started rubbing her clit. Watching Dipper fuck Pacifica was exciting in a different way than watching Dipper fuck Wendy had been: Whereas Wendy had known that Mabel was watching, Pacifica had no clue. Then there was the fact that the girl was a former rich-bitch frenemy—a hot blonde one—turned thirteen-year-old prostitute. Witnessing this felt perverted in all kinds of ways, and Mabel didn’t doubt that this was the perfect thing to watch to check that voyeurism box. She kind of wished she had brought Dee along to see it, too, and Mabel mentally promised that she would bring Dee to the next thing, whatever the next thing turned out to be.
Having just gotten off in Pacifica’s mouth, Dipper was really taking his time fucking the girl, and Pacifica seemed to be enjoying it. Mabel briefly wondered whether Pacifica was faking—being a prostitute with a paying customer—but Mabel could hear the genuine horniness in Pacifica’s sounds of pleasure as readily and clearly as she could hear it in Dipper’s soft grunts and moans. Mabel supposed that Dipper was in the habit of trying to please his partner, paid or unpaid, and Mabel felt proud of herself for having taught him such good sexual habits.
This is definitely a two-hander, she thought, licking her lips at the sight of Dipper’s cock going in and out of that sweet little pink pussy. As she continued to watch and rub her love-button, Mabel reached her other hand up under her sweater and into her bra to fondle one of her breasts.
At some point, though, Mabel found that feeling herself up wasn’t sufficient, so she moved that hand down under her skirt next to the first one so she could finger-fuck herself while rubbing her clit ever faster. Soon she got into a rhythm matching that of her brother and his hot, blonde, underage whore.
The rhythm was a fast one, because Dipper was pumping Pacifica like mad now. Pacifica worked her body against Dipper’s with equal vigor, and she moaned loudly and repeatedly. What was more, Mabel could almost feel Pacifica’s desire and pleasure herself, and she wondered if this was what Dee had meant about Mabel being able to sense arousal in others.
Dipper was starting to grunt with every thrust. Pacifica, too, was getting louder, panting and moaning ceaselessly as she worked her body fast and hard against Dipper’s. They were both getting close to orgasm, Mabel knew, and it wasn’t just their vocalizations that told her so. It was like the hornier they got, the easier it was for Mabel to sense their lust.
C’mon, Dipper, Mabel thought. Shoot a nice load in her. I bet she’ll love it and cum like crazy.
“Oh Dipper,” Pacifica panted, “I’m close, I’m so close…”
“Me too,” Dipper gasped.
He hammered Pacifica’s pussy even harder, and a moment later, the blonde girl was screaming and Dipper was grunting loudly as they both came. Mabel managed to mostly stifle her own cry of ecstasy as she came along with them.
Oh wow, she thought, panting as she came down from the peak of pleasure. That was awesome. Score another one for Dee.
The thought made her grin. Then her grin turned crooked as a thought came to her.
Oh crud—I was supposed to sneak away when they were fucking! How am I going to get out of the closet now?
In the back of her mind, Mabel supposed that she was technically bisexual now and that there must be a good “out of the closet” joke in there somewhere. But she managed to stay focused on the problem at hand.
She peered out through the slats again. Maybe she would get lucky, and Pacifica would want to go to the bathroom to wash up before escorting Dipper out. Or maybe she’d fall asleep, or suddenly remember that she had an appointment to blow some biker at the diner and rush out.
“I’ve got to confess, Dipper,” Pacifica said, still lying next to the boy, “I’ve fucked dozens of guys since I started this little side business, and you’re the first one ever to make me cum.”
“Wow,” Dipper replied. “If you were trying to feed my male ego, that really hit the spot.”
“It should, because it’s actually true,” Pacifica replied. “Soooo, I was thinking…What if I throw in a free third half for this half-and-half?”
Dipper tilted his head to the side. “Well, I dispute your math, but I really want to hear more.”
Pacifica’s fair cheeks were already pink from the fucking, and the pink went a shade darker as the girl said, “The thing is, even after fucking all those guys, there’s one way that I’m still a virgin. Maybe you could, you know, cure me of that.”
Dipper’s eyebrows rose just as Mabel’s did.
“Wow,” Dipper said. “Well, I’d be happy to, you know, open your back door. Have you got some lube?”
“Of course,” Pacifica replied. “It’s not like I get wet for those truckers…at least, not as wet as I got for you.”
Oh no, Mabel thought, remembering the tube of lube she’d found with the other hidden items behind the shoe rack. What if she comes in here to get it?
To Mabel’s great relief, Pacifica opened her nightstand drawer and took another, smaller lube-tube out of it. She set it on the nightstand and turned back to Dipper.
“How about I help you get hard again?” she asked sexily, pressing her bare breasts against Dipper’s side.
“Sounds great,” Dipper replied.
Pacifica scootched down on the bed until her face was right above Dipper’s crotch. Then she took his half-hard cock into her mouth and suckled it. Mabel was tempted to flee the closet right then, but she knew there would be a risk of Pacifica spotting her out of the corner of her eye as Mabel went out the bedroom door. No, Mabel thought, she needed to wait for Pacifica to be well and truly distracted.
It didn’t take long for Pacifica to suck Dipper back to hardness again. He must be pretty excited to do her in the butt, Mabel thought. I get it; she’s an anal virgin and she’s got a really nice butt. I wonder how much she’d charge me just to let me play with her cute ass for five minutes? Oh, who am I kidding, I’d want twenty.
So Mabel watched intently as Pacifica turned around and braced herself against her bed’s particle-board headboard, thus giving both Dipper and Mabel a good view of her ass.
Oh yeah, Mabel thought. I’d pay money to play with that.
“Wanna lube me up?” Pacifica asked.
“Sure,” Dipper replied eagerly.
He grabbed the tube of lube off the nightstand and squeezed some of the clear gel onto his finger. Then he used his other hand to hold Pacifica’s asscheeks open while he circled his lubed finger around her pale-pink asshole and then pushed about an inch inside, pumping his finger slowly in and out.
“Ooooh, Dipper, you naughty boy,” Pacifica moaned. “You’ve done this before. I bet whoever she was had a very good time.”
“Well, yeah,” Dipper replied, withdrawing his finger and wiping it off with a tissue from a box on the nightstand. “I mean, it was her idea.”
Pacifica looked back at him and purred, “Sounds like you like girls who know what they want.”
“Yeah, I guess I do,” Dipper replied. Then he glanced at Pacifica’s bubble butt and grinned. “Right now, what I want is that ass.”
“Then slide on in, lover.”
If Mabel had heard Pacifica’s words spoken by someone else, or if she’d merely read them instead of hearing them, Mabel would have assumed that they were just part of the act—a prostitute faking sexual desire for her client. But Mabel could hear the sincere lust behind Pacifica’s words. And Mabel could sense Pacifica’s lust, too.
Maybe she’s always wanted to try it in the butt, Mabel thought, but she never had the right boy to try it with until now. I’m glad I could help give her that, even if I can’t tell her I was involved. Or that I was spying on her while she boned Dipper. Or that I’ve been searching her whole house…Wow, I just went from feeling good about myself to feeling kind of icky.
The thought took some of the fun out of watching Dipper ease his cock into Pacifica’s gorgeous ass, and hearing Pacifica moan when he did. It was time to bail, anyway, which Mabel knew when Pacifica closed her eyes and began to move with Dipper as she savored her first assfuck.
So Mabel put the straps of Dipper’s backpack over her shoulders, crawled out the closet door, slipped downstairs, snatched up her shoes, and silently fled the house. But her guilt over betraying Pacifica’s trust didn’t stop her from climbing the tree again, re-donning the surveillance headset, and watching through the bedroom window as Dipper assfucked Pacifica to another loud climax.
***
It was late when the twins got back to the Shack. Dipper was understandably tired but still wanted to look at the new map, unrolling it after Mabel closed their bedroom door.
“This has got to mean something…lead somewhere…” the boy said, blinking his bleary eyes at the map’s array of oddly arranged symbols.
“Yeah, it probably does,” Mabel replied. “But I think banging the hell out of Pacifica is all the adventure you need for tonight. We’ll get on this in the morning.”
“Maybe…you’re right…” Dipper said, then got into his pajamas and dragged himself to the bathroom.
Dipper fell asleep pretty much the moment his head hit the pillow. Mabel, now in her nightgown, decided to take this opportunity to grab Fun-Size Dee out of her purse and take the ancient spiritual adviser downstairs and out to the back porch for a chat.
Dee was indeed pleased to hear about Mabel’s successful act of voyeurism. But Mabel left out the parts about actually sneaking into Pacifica’s house and searching through her stuff. Mabel still felt guilty about having snooped on a friend—because yeah, Pacifica was a friend now—in more than just a sexual way, and Mabel didn’t want to get into all that with Dee.
After finishing her story and being roundly praised by Dee for her efforts, Mabel then mentioned what Dipper had said a few nights ago about how he would fuck five-year-old Wendy if he could. To Mabel, this was just an interesting aside, but Dee seized on it.
“Mabel,” Dee said, “this is very exciting news.”
“It is?” Mabel replied, eyebrows rising. “How come?”
“Dipper has confessed to you that there is at least some circumstance under which he would fuck a five-year-old girl. An extreme act of perversion like that would give our powers a tremendous boost.”
“Yeah, I guess it would. But he only said he’d fuck five-year-old Wendy. Unless you’ve got a magic tape measure from the future, there’s no way to make that happen.”
“I…don’t claim to understand that,” Dee replied. “But my point is, if Dipper is sexually attracted to one very young girl, there are probably others about whom he has—or could have—similar feelings. If you were to help him get his cock into such a girl…well, that might be the very thing that gives you the power to change the world.”
Mabel wasn’t so sure about changing the world, but pulling off such a huge act of perversion did seem like an exciting challenge. Not to mention that ever since that late-night conversation with Dipper, Mabel had felt a progressively deepening curiosity about what sex with someone younger than herself would be like.
“You know what?” Mabel said. “I might actually know how to make that happen. I’ll tell you the deets tomorrow.” Then Mabel yawned. “Right now, I’ve gotta get to bed. Voyeurism is weirdly tiring.”
Mabel put Dee back in her purse and headed inside. As she quietly climbed the stairs again, she thought back to when she’d sneaked up the stairs at Pacifica’s house and got her first peek into the girl’s room. Which made Mabel realize something: Pacifica’s bedroom hadn’t had a single painting on the walls. No autumn landscapes, no sad clowns. Had Pacifica been lying about being a paint-by-numbers enthusiast when Mabel ran into her at Hobby Horse?
It also occurred to Mabel that she hadn’t yet examined the second item she’d taken from Pacifica’s secret stash.
