15. Mabel’s Guide to Orgies
“I’m not sure I want to do this,” Dipper complained.
Wendy rubbed his shoulders. “Dude, if you don’t, Mabel’s gonna go crazy. The same way I would have if you’d turned me down when I was hooked on the pheromones.” She kissed his cheek. “Come on, you don’t have to fuck her. We just all go into Pacifica’s big exercise room, you do me, Tambry and Pacifica take care of her. That’ll be enough.”
It was mid-morning on the day after Mabel’s arrival in Gravity Falls. They’d driven out to Pacifica’s riverside house after breakfast—a huge one for Mabel, and a lonely one for Dipper, because he stayed upstairs and out of his sister’s sight while eating his cereal. He and Wendy drove in her Jeep, Mabel, Pacifica and Tambry in Pacifica’s convertible, with Paz at the wheel and Tambry and Mabel making out in the back seat.
“This is a great place!” Mabel pronounced as they entered Pacifica’s mini-mansion. “I love it already!”
“That’s because of pheromones,” Pacifica said carelessly. “My house smells like money.”
“Let’s get started?” Mabel begged, unfastening her skirt. “You promised!”
“Through here, down these stairs, and in here!” Pacifica said, leading Mabel. They walked into a room with one glass wall. Under Pacifica’s direction, Tambry and Mabel, now bottomless, hauled down and laid out exercise mats until the floor that wasn’t already covered with a treadmill, an exercise bike, and a stair climber was covered with mats.
“What’s that?” Mabel asked as she peeled off her top. “That sort of little greenhouse on that side?”
“That’s the spa and hot tub,” Pacifica said. “If you’re a good girl, we can go in there later.”
“Where’s Dipper?” Mabel asked, sinking to her knees and rubbing her pussy. “You said he was coming!”
“He’ll be here, Mabel,” Tambry said as she undressed. “But remember, you can look, but you can’t touch.”
“I need his dick inside me,” Mabel moaned.
Pacifica held up something that looked like a python made of squishy lavender PVC. “This will feel the same,” she said. “Mabel, lay on your side. Tambry, scissor her.”
Mabel obeyed, and Tambry pressed her pussy against hers. Both girls were wet, and Mabel involuntarily began to grind. “I never used to do this,” she said, turning pink. “Just with guys.”
“Mm-hm,” Pacifica said as she stripped down to a sheer black leotard—with no crotch. “How many guys?”
“Three,” Mabel said. “But just one time with Leon, ‘cause he was my first and didn’t really know what he was doing. That feels good, Tambry.”
Pacifica knelt on the mat beside Mabel and started to lube up the double dildo. “Tell me when you want to fuck,” she said. “Tam will take one end, you’ll take the other, and I’ll coach.”
“Your boobs look so sexy through your top,” Mabel said. “Where do I get one?”
“It’s a bodystocking leotard,” Pacifica said. “Three hundred dollars at Discreet Street.”
“Look at your pretty nipples. I wish my nipples were long and pink.”
“They’ll get there,” Pacifica said. “Back off, Tambry. Lay on your back now, Mabel. Spread your legs. Grab them and pull them way back. Get your butt up off the mat. Good girl.” She started to rub one head of the double dildo up and down Mabel’s wet, quivering slit. “You want it?”
“Yes,” Mabel said with a moan. “Put it in, please!”
“As me nicely,” Pacifica said with a smirk.
“Pacifica, please put it in my pussy.”
“Here goes. Don’t squeeze it out, you little slut! If you want it in, let me push it in!”
Closing her eyes and breathing fast, Mabel lay reasonably still while Pacifica slipped eight inches of the dildo deep inside her. “Tambry, your turn,” Pacifica said.
“I’ll do it myself,” Tambry said, grasping and inserting the free end of the lavender sex toy. “This is a good one, Pacifica! All right, Mabel, now we’re gonna start fucking.”
Pacifica had turned on a mushroom-head vibrator. She began to massage Mabel’s love mound with it. “Want to turn back on your side?” she asked. “Better action that way.”
“Yes, please, Pacifica!” Mabel said.
“Carefully. Here, you can finger my pussy while Tam fucks you.”
“Thank you!”
The three girls became so involved that Mabel didn’t even notice Wendy and Dipper coming in until they knelt on the mat three feet away from Mabel. Then Mabel blinked. “Dipper! You’ve got a big dick!”
“And I promised to let you see me make love to Wendy,” Dipper said.
“Me on the bottom,” Wendy said.
“She’s done it with three boys so far,” Pacifica told them.
“You weren’t supposed to tell Dipper that!” Mabel whimpered.
“He’s done it with seven girls,” Wendy said. “Nothing to be ashamed of. It’s not a contest. Now, see, I’ve got my legs wide open. I’m rubbing my slit to make it nice and wet. Dipper’s stroking his cock to get it lubed up. Know what precum is?”
“Uh,” Mabel said. She was moving rhythmically as Tambry slowly fucked her with the double dildo. “I—no?”
“It’s the clear stuff that comes from a guy’s dick when he’s really horny,” Wendy said. She reached down to touch the tip of Dipper’s penis and pulled her finger back with a sagging clear string attached. “It’s not cum, it’s PRE-cum, get it? It’s a natural lube.” She popped her finger in her mouth. “And it tastes kinda bland, but a little salty. Now, Dipper, rub your cock head on my pussy. Show Mabel how it’s done.”
Dipper obliged, feeling a little distracted. Mabel lay there with Pacifica crouched just behind her head, reaching down to stimulate her breasts—and Mabel had very, very nice breasts, indeed—with the vibe. Tambry was smiling as the purple dildo slipped in and out of both girls. And everyone was watching him and Wendy.
“Now I’m all hot and bothered,” Wendy said, reaching down to grasp Dipper’s engorged cock. “I’m gonna help Dipper, ‘cause sometimes a guy can’t aim well when his dick’s all swollen up like this. So . . . here is the place, and now Dipper’s gonna push it in . . . ohhh.”
“This is my favorite part,” Pacifica said. “Look how her love mound swells up just from his cock going in!”
“It’s so long,” Mabel said as if talking in her sleep.
“And look, she takes every inch of it in. Amazing!” Pacifica said.
Tambry nodded. “You can see the bulge way up in her stomach. Okay, man, now fuck my girlfriend!”
Mabel put her thumb to her mouth and bit it with a whine.
Pacifica moved the vibe back down to her clit. “You’re feeling the exact same thing,” Pacifica said. “Fuck Tambry harder.”
Mabel, on her side, began to thrust as much as she could. Dipper, in the saddle, fucked Wendy with long, slow strokes. Wendy gasped, “This—this kind of fucking—will drive you crazy, Mabel. It feels like he’s a mile long. Okay, lover boy, now let’s speed it up!”
“It even sounds sexy!” Mabel exclaimed, reaching down to pinch her own nipples. Dipper’s cock was making a slick, slapping sound as he pounded Wendy. She arched her back.
“Leg-lock him!” Tambry urged. “Guys love it when the girl does that!”
Wendy heard and used her legs to hug Dipper, crossing her ankles. He adjusted the angle until her heels rested on the lower swells of his butt. “Wont last long,” he said.
“Give it to me, Dip,” Wendy said softly.
Pacifica asked Mabel, “Do you want to see him cum?”
“Yeah!” Mabel said, sounding on the verge of tears. “Cum, Dipper! Let me see you!”
“Just . . . a . . . second,” Wendy murmured. “I’m almost—Fuck, yeah, you made me come! Quick, pull out, give me a facial!”
Dipper rocked back and his dick popped out of Wendy and bobbed up, slapping his belly.
“So good,” Mabel moaned. “It looks so good—”
Wendy reversed and, lying on her stomach with her torso raised, like the Sphinx, she grabbed his cock and started to beat him off. “He’s gonna cum, Mabel!” she announced.
Then the spurt of hot cum splashed in her face, covering her cheeks and forehead, dripping down in white drops, and she quickly covered his cock head with her lips and took the last jets directly in her mouth. “Was it good?” she asked, turning her beautiful green eyes up to look at Dipper.
“I loved it,” he said, reaching to wipe a drip of cum off her left eyelid. “Sorry for the mess!”
“I love your cum,” Wendy said.
Pacifica knee-walked over. “I’ll take care of the mess,” she announced, beginning to lick Wendy’s chin, cheeks, nose, and forehead. “Yum, it’s delicious.”
“Taste it?” Mabel pleaded.
“Sis, that’s—”
Pacifica said, “Oh, you two go to the shower. It’s through that door.”
Wendy pulled Dipper up and they vanished through the doorway. By then Mabel had felt a flashing orgasm. She rolled onto her back again, gasping, as Tambry pulled out the dildo and started to lick her.
Pacifica leaned over her. “Mabel, you really want a taste of your own brother’s cum?”
“Uh-huh,” Mabel grunted.
Pacifica leaned over. “Open your mouth.”
And Pacifica came in for a kiss. Mabel sucked her tongue, tasting not just Wendy’s juices, but a strangely haunting, slippery substance that must be Dipper’s cum. “M-more,” she begged.
Pacifica wiped her lips with her thumb. “This is all you get,” she said. “Be sure to thank me.”
Eagerly, Mabel sucked the rich girl’s thumb. “Thank you, Pacifica,” she said humbly.
Pacifica stroked her hair. “So what do you think? Are you ever going to go back to guys?”
“I—I love a guy’s dick in me,” Mabel murmured.
“Uh-huh. So you’re giving up on girls?”
Mabel’s blush deepened. “I love the way pussy tastes, too,” she said.
Tambry had come up to lie beside her. “I now pronounce you technically bisexual,” she said cheerfully. “From now on, you’ll never be without a date on a Saturday night!”
Pacifica advised, “When you go back to college, never team up with a girl who’s totally lez. She’ll try to get you off guys. Always go for the bi girls, like us.” She put her hand on Mabel’s cheek. “So, I have my strap-on here. Want to put it on and fuck me with it? See how a guy feels?”
“I—yeah, I’d love that,” Mabel said. She frowned a little. “My nipples feel weird. Are they bigger?”
“Little bit,” Tambry said. “You may leak a little milk now and then.”
“Cool,” Mabel said. “Uh, how do I do the strap-on?”
“First,” Pacifica said, “we put it on you, then in you, and then strap it on. Mind if I get out of the leotard?”
“Let me watch,” Mabel said as Tambry got busy fitting the strap-on. “You’ve got such beautiful, creamy boobs, Pacifica.”
“They’re all yours,” Pacifica said, guiding Mabel’s head down so she could suck on her nipples.
“You guys are all set,” Tambry said. “I’m gonna go find Dipper and Wendy. Then is it okay if the three of us get in the hot tub?”
“Have a great time,” Pacifica said.
She had Mabel go down on her—a little awkward with the fake penis jutting out, but Mabel twisted her hips and made it happen—and then enjoyed the way that Mabel went about it so enthusiastically. She could tell that Dipper and Mabel were twins. Their tongues were so much alike . . .
“I’m ready,” Pacifica said. “Put it in me.”
Mabel took a stab or two. “Help me?”
“Yeah, see, that’s what Wendy was showing you,” Pacifica said, seizing the dildo and directing it right into her cunt. She also switched on the vibrator concealed in the plastic ball sac.
“Oh, Mabel likes!” Mabel said. “Now, just, uh—like with Tambry and the dildo?”
“Yeah, start simple, just back and forth, in and out . . . that’s good, that feels right. Now you can pump a little harder. Feel my nipples against yours?”
“So hot,” Mabel said. “Uh, are you gonna—is Wendy meaning to—I mean you and Tambry--?”
“We’re all going to keep fucking your bother,” Pacifica said. “Nobody’s jealous and nobody’s selfish.” She urged Mabel to press upward more. “That’s good, that feels so good.”
“And me?” Mabel asked in a small voice.
Pacifica leg-locked her. “Every time you’re here, we’ll make love with you,” she said. “Not Dipper, but me, Tam, and Wendy. But if you bring a guy and you’re fucking him, don’t ask us to join in. We kind of have a deal—yeah, faster!—with Dipper. But I can hook you and your boyfriend—harder!—up with another bi girl or two if you—yes!”
“I’m cumming!” Mabel said. “Whoops, what was that?”
“You squirted,” Pacifica said. “Me, too. That’s one effect from smelling Dipper’s cum. Congratulations, guys like girls who squirt.”
“What does that taste like?” Mabel asked.
Pacifica released her from her leg-hug. “Pull that thing out of me, go down, and see for yourself.”
By Monday evening, Mabel’s lust for Dipper had dulled. “But,” she said as they packed her car for her return to college, “I don’t think it’ll ever go away completely.”
“As long as it’s just sisterly love,” Dipper said. He kissed her cheek. “Drive carefully and call when you get there.”
“I will,” Mabel said, returning his kiss. “Dipper? You don’t think it’s weird that we—me and Paz and Tambry and Wen—that we--?”
“No,” he said. “I do it with them, too, how could I think it’s weird?”
“Well,” she said. She gave him a wistful smile and reached down to pat the front of his jeans. “You and this guy have fun. I’m going back to college and, uh, you know—”
“Rethink everything,” Wendy said helpfully. “Bye for now, Mabes. It was sweet making love with you.”
Mabel finally drove away into the twilight. It was a long drive, and she wouldn't get back to California and college for seven long hours. However, she thought, there was a convenient rest stop about two hours from college, and she could stop there and enjoy the protein drink that Pacifica had thoughtfully given her. That would help . . .
As they watched Mabel's car vanish down the drive and toward town, Wendy reached over and squeezed Dipper’s butt cheek. “Did we do everything right?” she asked. She and Dipper were standing on the gift-shop porch as twilight came on.
“Do everything right? Who knows?” Dipper said. “But you girls made Mabel happy. And if she’s bi now, she’s still Mabel."
“It’s a nice warm night for a change,” Wendy said. “All the snow’s gone. Soos and Melody will be back in a few weeks. Then what are we gonna do?”
“I don’t have any suggestions, except keep making love,” he said.
“Yeah, that’s a given. You can move in with me, man. We can spend weekends at Pacifica’s lake house with her and Tambry. Sound good?”
“Sounds fantastic,” he said.
“Then,” she said, “I think it’s dark enough. Little bit cool, but a nice evening. What say we both strip down and seal it with a fuck right here on the porch?”
And so they did.
