8 Wheels and Deals
As promised, next morning at nine Stanley drove up in his red-and-white El Diablo and they piled in, Mabel calling shotgun. “You guys get plenty of rest?” Stan asked as he expertly backed the big car and headed out the driveway.
“Like a couple of babies!” Mabel said. “How many cars can we get?”
“One,” Stan said firmly. “I talked to—ugh—Gideon on Wednesday, and he says he’s got like five or six compacts that ain’t too badly banged up and run okay. You knuckleheads pick one of them!”
“How much are you gonna spend on it?” Mabel wheedled.
“Meh, maybe I could go up to three hundred a month. Insurance is on top of that, so cap it at say four-fifty.”
The town had not changed very much at all. Some things were gone, some businesses had become something else, the streets had been repaved, and now downtown had four traffic lights, not two. The new white metal water tower, minus the graffiti of a giant explosion or, looking at it another way, a big muffin, sort of altered the skyline, but along Main Street of the businesses were still there. Dipper, looking out the window from the back seat, said, “It looks normal. I mean, nobody’s wearing masks or anything!”
“Yeah, as long as they can keep the germs outa the valley, it’ll stay that way,” Stan said. “If the stupid government guys hadda listened to Old Man McGucket this whole epidemic mighta been over and done by now. Hey, you talk to your mom this morning?”
“Called her at breakfast,” Dipper said. “Dad’s home and doing fine, but he’s complaining because they’re sleeping in the guest room, and she won’t let him climb the stairs. But he said he’s checking in on the computer at work for an hour today just to catch up on emails and stuff.”
“Good, keep ‘im busy and he’ll get better quicker. Here we are, Gleeful’s Discount Auto Mart.”
“Looks just the same,” Mabel said. “Big helium-filled dollar sign and everything.”
“Yeah, just air in it now, helium’s got expensive.” Stan shut off the engine and they opened the doors.
“Well, howdy!” Gideon came out of the office, now taller but still pudgy, and losing a little of that bouffant hair. He wore a light blue suit with a gray pinstripe and a matching gray tie. He rubbed his hands together. “Mabel and Dipper, you sure are a sight for sore eyes. Stanley, I hope you’re well.”
“Fit as a fiddler crab,” Stan said.
Mabel, to Dipper’s surprise, took both of Gideon’s hands in hers. “Oh, Gideon, we’re so sorry to hear about your dad.”
“Thank you,” Gideon said with a sad smile. “Yeah, it was a shock, but he never would have any truck with doctors and takin’ his meds. Mom and me like to think he’s in a better place now. Dipper, you’re looking fit.”
“Thanks,” he said.
"You workin' out?"
Mabel piped up: "He sure is!"
Stan rumbled an interruption: “I promised these guys we’d pick out a car for them this morning, So if you can show me what you got on hand, we’ll make a decision.”
“That’s what I like in a customer,” Gideon said, again rubbing his pudgy hands together. “Get right to business. All right, folks, come back this way, I got six possibilities lined up and ready for your inspection.”
None of the cars was great. Of them all, only the Capricorn looked acceptable, nice dark-blue finish, decent interior, and when Stan raised the hood, the engine didn’t look corroded and no possums scrambled out. Aside from that, Dipper couldn’t tell much. All he knew about auto engines was that he recognized one when he saw it.
“Kind of cramped,” Mabel said when she got behind the wheel and looked back over her shoulder. “Not much legroom in the back seat if we want to go somewhere with friends.”
“Yeah, you get that in compacts,” Gideon acknowledged. “Well, let me see. There’s two other possibilities right in the same price range as these beauties. One of ‘em’s a thirteen-year-old Malamute, but she ain’t got but forty-five thousand miles on ‘er. The other’s a—well, let’s look at the Malamute first.”
That was a midsize car, red, with a somewhat worn but clean interior, standard two bucket seats with a central console in front, an adequately wide bench seat in the back, with more legroom than the compacts. “This might do,” Mabel said, sitting in back. She experimentally stretched out and found she could lie more or less straight on the back seat. “Okay, just for giggles, what’s the last one you mentioned?’
“Well,” Gideon said, shrugging, “It ain’t so much a car as—that’s it over yonder by the fence.”
It was a pickup truck.
Not a huge one—a Japanese model, a Hanzo Ridgeway, but it did have an extended cab with both front and rear seats. And, surprise, the front one was a bench seat!
“You don’t see that these days,” Stan said. “I mean, my El Diablo’s got front and back benches, but it goes back to the 1960s!”
“Yeah, the owner's huntin' dog tore up the front passenger seat of this ‘un, and the owner replaced the two front bucket seats with this special wide bench seat. Between you an’ me, he was a wide load himself! Anyhow, he used this truck just in the valley when he was on jobs—he was a plumber and electrician—bought it new, drove his other car for everything else but work runs. Not in bad shape, considering its age, got fifty-two thousand on the odometer, had a new transmission put in two years ago, runs smooth. Not great on gas mileage, though.”
“We’re not gonna drive it to California and back!” Mabel said.
Dipper agreed. “With the pandemic, we’ll just use in in the valley,” he said.
“You guys sure you want a truck?” asked Stanley, rubbing his chin.
Dipper was thinking, Warm nights, might put a mattress in the truck bed, making love out under the stars.
Mabel was thinking, One couple in the cab, one couple in the bed, a mini-orgy on wheels!
Gideon suggested they take it for a test drive—“Y’all cruise to the lake and back and take turns at the wheel.”
Mabel took the first turn. Luckily, the truck had an automatic transmission. “Seems so big!” she exclaimed as they turned out of the lot and headed toward the lake.
“That’s what all the girls say when they first see it,” Dipper told her, and immediately he turned red.
“Ha! You made a sex joke!” Mabel chortled. “Hey, let’s name this truck ‘Big D!’”
“For Big Dick?” Dipper asked.
“Yeah!” They laughed like loons. At the parking lot for the lake beach, they changed places.
Dipper said, “Seems like we’re sitting way high up, doesn’t it?”
“Yeah, but you get a great view of what’s ahead. Let’s take it!”
“Sure, if gruncle Stan will go for it.”
When Dipper pulled the pickup back into the Gleeful lot, Stan asked, “Do you want it?”
They looked at each other. “Yes!” they both said at once.
Because it was older and a truck, the lease turned out to be about a hundred dollars a month cheaper than Stan had prepared for. That pleased him. The paperwork took half an hour, and Gideon even had a license as an insurance agent, so Stan signed off on that, too. Gideon gave them a receipt, and the truck was theirs
Well, leased, but Mabel was already calling it "our ride." Giden turned over two sets of keys, and Stan warned them to watch the mileage they racked up. “You go over five hundred miles in a month, you’re gonna pay the overcharges yourselves!”
The twins wished Gideon a good day, and Mabel got behind the wheel and adjusted the seat. Dipper had to brace his feet and help her tug it into a comfortable position. “Back to the Shack?” Dipper asked as Stan turned his classic car out onto the street ahead of them.
“No way! I wanna get on the highway.”
“Where are we going, then?”
“The most romantic spot in the valley!” Mabel said. “To Lookout Point!”
“Um—”
Dipper hesitated because Lookout Point held bad memories for him. That was where he and Stan had interrupted a make-out date between Robbie and Wendy that time when Robbie was trying to hypnotize her with a back-masked message on a CD. In the end, an angry Wendy had ditched Robbie, brushed Dipper off, and had run downhill into the forest to walk home, miles through the woods.
Mabel seemed to read his mind. “Wendy's way over that, brobro! You know you wanna go up there with her and put in some lovin’. And a lot of dick! Put it WAY in, hey-yo! So let’s go up and experiment a little bit!”
Dipper went along with the idea. The truck wound around the curves of the back road and handled well, and after a while Mabel parked it at the overlook. Lookout Point offered a fantastic view of the town, the lake, and the falls—a distant view. On balmy nights, it was a notorious make-out site for teens, but in the mid-morning of a cool pre-spring day, they had it all to themselves.
“Think a guy and girl could get it on in this truck?” Mabel asked.
“Probably. The front seat’s awkward. I mean, they could sit side by side, but if they tried to stretch out, the wheel might get in the way—”
“Let’s try the back!”
“Mabel!”
But she had already clambered out, around, and into the back seat. “Come on, Dipper! We want to make sure everything’s comfortable for Wendy!”
He joined her in the back. “We can ‘t do anything crazy,” he warned. “It’s broad daylight!”
“We’ll be restrained,” she said with dignity. Then she kicked off both her shoes, arched her back and raised her butt, and shoved her shorts and panties down and off.
“That’s . . . not very restrained,” he said.
She stuck her tongue out at him. “Look at what I can do!” Raising her butt off the seat again, she tugged her sweater down. It was long enough to cover her pussy with maybe an inch to spare. “There! Decent again!”
“I can’t exactly do that,” Dipper said. “Besides—”
“Nobody’s around for miles,” Mabel urged. “Take off your shoes and jeans and shorts. Nobody’s here to see us, anyhow.”
“If the cops come by or something—”
“I’ll take care of it! Come on! Remember, you’re doing it for Wendy!”
Oh, well, what the hell. For Wendy.
Unlike Mabel, who had simply wadded up everything she wore below her waist, Dipper carefully removed shoes, socks, jeans, and shorts. Despite his misgivings, his dick was already hard and throbbing.
“Glad to see you’re glad to see me!” Mabel said. She was leaning against the rear door, one foot up on the seat, knee crooked, giving Dipper a clear view of her love valley, shiny and pink. “We really really really ought to try fucking.”
“Mabel,” Dipper said. “That’s kind of a squicky idea for me.”
“Mm, maybe we can talk about it later. Right now I wanna watch you stroke your cock, Brobro. We don’t do enough of that in the daylight. You look so ready.”
“It’s embarrassing, jerking off with someone watching,” Dipper complained.
“No it’s not! Look at me! Mm, pretty pussy, nice little pussy, let me make you purr.”
Her fingers lovingly stroked her pouched labia, pausing to make tiny circles on her clit, which was just visible, peeking from its pink sheath. “I’d love to put my fingers inside and let you watch, but you’re not giving me a show in return, so . . . .”
Dipper closed his fingers around his shaft and began to rub up and down slowly. “There. That’s the way I usually start.”
“Work on that pretty purple glans for me. So tight and shiny! Let me see some pre-cum oozing out.”
“Open up your pussy so I can see, then.”
“Here you go.” With the first two fingers of her left hand, Mabel spread her pussy lips. She reached around her butt with her right hand and started to stroke and rub the frilly inner pink lips, so wet already that they gleamed. “Nice?”
“Yeah,” Dipper said. He rubbed the head of his cock and felt the ooze of clear pre-cum starting to flow from the slit.
“Mm. Want to switch?” Mabel asked. “Turn more toward me.” She scooted her ass across the bench seat and raised up and settled so his bare left foot was beneath her soft right buttock. She reached for and took hold of his cock. “Now you finger me. And feel free to watch, I don’t mind!”
Dipper’s heart pounded at the thought that he was fingering his own twin’s pussy and she was stimulating his dick. He couldn’t help licking his lips. Her pussy had opened like a beautiful orchid at his touch, and he could see the whole wonderful spread of it, even the promising dark opening that seemed so eager for a cock. With a little difficulty he moved closer, stimulating her clit with his thumb and pressing his fingers into her depths.
“Yeahh, girls like that,” Mabel breathed. “Don’t stop. I’m gonna let go of this beautiful cock until I get more comfortable.”
She wormed the sweater up and off. Under it she wore no bra. Her full round tits jutted their engorged, coral nipples lewdly. Dipper couldn’t take his eyes off them. “You’re really beautiful, Sis.”
“Yeah, well, I just stripped 'cause when you cum I don’t want you to spurt all over my nice clean sweater. Cool in here, so let's heat things up. Aim for my boobs and face. I’ll even open my mouth if you think you can hit it!”
Now Dipper was flicking her swelling clit with his thumb. She leaned back but surprised him by moving so she could jerk him off not with her hands, but her feet. “Um—” he said.
“Not as good, huh?” Mabel moved her feet. “Okay, brobro, you get to cum first, but then you’re gonna owe me!”
“We’ll see who cums first.” By trial and error he had discovered that Mabel was particularly sensitive in a special spot, a super smooth, slippery patch just above her clit. After lubing his thumb with her juices, he suddenly started to give that place extra special attention, while moving his hand enough to pump her pussy with his middle finger, curling it to seek out her G-spot.
Mabel had reached to clasp his dick again, but she gasped and fell back, drooling a little. “Oh my gawd, Dip, th-that’s—don’t stop whatever tyou're doing, it’s great! Unnhh!”
“If you cum first,” he teased, “you have to suck me off!”
“Y-yeah, yeah, but don’t stop! Faster! Mm-ahhh! Oooh FUCK!”
He actually felt her pussy clamp down on his finger and the warm gush of her fluids. She squirmed, bucking her hips, and her head thrashed back and forth. In the light of day, the change in her was spectacular—a strawberry flush filled not only her cheeks, but her whole torso, and her tits practically glowed with it. Her areolas puffed and her stiff nipples seemed to shrink as the swelling pink flesh almost engulfed the erect tips. Her toes even clenched hard.
“I guess you came,” Dipper said. “Unless you’re faking it.”
“Whoo! Not fucking—I mean not faking it! That was fan-fuckin'-tastic! Where’d you learn that stuff? It wasn’t from me!”
“Natural talent, I guess,” he said, moving back across the bench seat. “Now I think you owe me a blowjob.”
“Hunhh. Uh, yeah. Let me uh, clear my head a little bit. Wow, brobro!”
Dipper tilted his head, tensing all over. “Wait, I hear a car.”
“Oops!" Mabel yanked her sweater on, mussing her hair. “Project Suckoff temporarily suspended!” She hopped out of the car and into the driver’s seat as Dipper reached down for his shorts and jeans. Mabel fired up the truck, backed, and turned out just as a sheriff’s car with Durland at the wheel came around the curve. Mabel waved at him as she headed down the hill.
“Did we lose him?” Dipper asked, struggling to get both feet into his shorts, but not into the same leg opening.
“Think so. Don’t see him in the rear-view. Wanna climb over the seat so I can—”
Dipper fastened his seat belt. “No, just drive. I’ve lost my hard-on, anyway.”
“Aww! Don’t worry, I’ll help you get a new one. The Shack?”
“The Shack,” he said decisively. He wasn’t able to get his jeans completely on. “But don’t speed or attract attention. We can’t risk the police stopping us when we’re both bare-assed!”
“Don’t worry, Mabel’s got this!”
It might have been the only time ever that Mabel didn’t go even one mile per hour over the speed limit. It took more than twenty minutes, but finally they arrived at the Shack. No cars in the parking lot. Mabel got out and Dipper handed her shoes, panties, and shorts to her. She put on the shoes.
“Come on,” she urged, grinning. “It's cold out, and I wanna pay my debt to suck-ciety! That’s a Mabel joke!”
Dipper got out, tugging the jeans up, and stepped into his sneakers, but carried his balled-up socks and didn't tie his shoelaces. “Keep your shirt on,” he said, trying to growl it like their gruncle Stan did.
“No way!” she held her shorts and panties bundled under one arm and carried her keychain in that hand. With the other she impishly flipped up the hem of her sweater and sashayed down the walkway to the gift-shop door, waggling her bouncy buttocks provocatively. “Come and get me, Dippingsauce!”
As soon as they were both inside the door, Mabel shoved her brother against the wall, slamming the door and reaching for his jeans.
“Nuh-uh!” he said as she crushed her mouth against his. “Rmummba gnngle fr—”
She broke the kiss, giggling. “It’s funny when you talk into my mouth! I don’t want you to put WORDS into my mouth, Dip, I want you to put your COCK into it!”
He grabbed her beneath her arms to prevent her from kneeling in front of him. “Mabel, remember, gruncle Ford sometimes comes over to use his lab! Let’s at least go to our room for this.”
“Aww. We gotta work on your impulsiveness. You don’t have any! Take off the pants anyhow and carry them. They’re hanging down under your butt now.”
Dipper gave up and stepped out of his jeans and shorts. Mabel tsk-tsked at his limp penis, shaking her head. “Come on, Sis will fix you up.” She grabbed his dick and used it as a leash to lead him to the stairs and then up to their bedroom. Inside, she closed and locked the door before peeling off her sweater again. “I like our new fuck-truck,” she said brightly.
“It’s pretty cool,” Dipper agreed.
Mabel hugged him as he pulled his shirt over his head and discarded it. “I could eat you up,” she murmured. In fact—”
She started by catching his bottom lip between her teeth and playfully stretching it. Then she licked and sucked her way down his neck, backing him up until he stood against the edge of the bed. She reached down to fondle his balls and licked his nipples hard, then sucked on them. “Interesting,” she said. “Your nips get hard, too, just like mine do!”
“I never noticed that before,” he admitted. “But it feels good.”
“Mm, tell me about it.” She squeezed his cock. “And this must feel pretty good, too. Look how my little Dipper has grown! Grab me a pillow.”
Dipper tossed one to the floor, and she knelt on it. “There’s my great big boy,” she cooed, nuzzling his dick as it swelled, rubbing it against her cheeks, throat, and lips. “There’s my favorite dick! I’m gonna get it nice and wet. Starting with these down here.”
With her hand on his dick, Mabel bent down to lick and suck on his balls, but after a moment she spat. “Puah! Hey, brobro, word of advice. You’re way hairy down here. How about you trim a little of the undergrowth? I mean, my pussy feels nice and clean now that I removed the surplus curly-wurlies. Let Mabel give you a trim?”
“I . . . don’t know that I’d trust you down there with a razor,” he said.
“I won’t hurt a hair on your scrotes! But your penis has like sideburns, and your balls are just too fuzzy for licky-licky fun. I’ve watched videos about manscaping, Dip. I know just how to do it.”
“Maybe,” he said. “But you said you were gonna—”
“Yeah, yeah, let me move up here to the no-hair zone.”
Mabel licked her way up the bottom of his shaft and then zeroed in on his glans. She did that suck-and-pop thing, purring at the way it made his hard-on suddenly stiffer. “That’s what you like, you naughty boy! Hey, did you like my laying back with my pussy spread out for you?”
“Loved it,” he said. “You’ve got a very pretty pussy, Mabel.”
“Oh, thank you! And I admire your prick, brobro.”
She went back to work, sucking and licking, and Dipper’s breath got shorter as his dick got longer. “Don’t just tease me,” he pleaded.
“Let me show you a trick Wendy probably will use,” Mabel said, tilting her head to grin up at him as she jerked his dick. “Tell me when you get real close.”
She sucked again, lavishing his cock head with her eager tongue. Then she started to bob, fucking him with her mouth. Faster and faster. He felt his stomach fluttering.
“Close!” he said between clenched teeth. “OW!”
Mabel was squeezing the base of his dick, hard. “Cut you off at the pass!” she said.
“Sis! That kind of hurt!”
“That’s the way a girl delays a guy’s orgasm. Makes it better when it finally comes, or that's what your girlfriend says. Wendy told me how to do it when we were discussing guys and their ways. Speaking of which—squirt in my mouth when you’re ready. I want it!”
Easing his butt forward, Dipper began to move his hips, thrusting into her hot mouth. She made contented little humming noises and sucked even harder. He heard the lushing, slushing sounds of her blowjob and felt the dizzying play of lips and tongue, felt her fondling his balls and encouraging him.
And this time he didn’t warn her. His dick pulsed and he came hard, gushing his semen into her mouth. She followed every movement, rising a little on her knees to keep his cock in her mouth, swallowing and gulping. Finally, he settled back down, and she momentarily let his dick bob free, but she grasped it and milked it with her hand, encouraging a last pearly spill to ooze into a drippy blob, which she licked up.
Then she whispered, “Lay back.”
She sprawled on top of him, trapping his dick against her lower belly, and nuzzled his neck. “I love you, brobro,” she said.
“I love you, too, Sis.”
“Not just as a sister, though.”
“No,” he said, putting his arms around her, cupping her bouncy ass with his hands. “Not anymore. I guess not.”
“Yeah,” she said, “but I know you love Wendy more. Hah. I even felt your dick trying to get hard when I said her name. That’s okay, brobro. Mabel understands. One day I’ll find a guy of my own.”
“Yeah,” he said, sadly.
“But until then, I don’t see any reason why you and I can’t enjoy this together. I mean, I’m not greedy. I think Wendy would be okay with us sharing you.”
She curved her back and rose, her breasts teasingly close, the tips brushing his chest.
He admired them and her sexy post-orgasmic expression and asked, “Did you and Wendy really fool around?”
“Some.” She smiled almost shyly at him. “Want to hear the story?”
Dipper sighed. “I . . . don’t know.”
She rolled off him but pulled him onto his side so they still lay close, facing each other. He gazed into her face, so much like a mirror image of his, but somehow beautiful, totally girly, not masculine at all. “It wasn’t all that much of a deal,” she said softly. “One day she was feeling all frustrated ‘cause her latest bastard boyfriend had done it with her, left her hanging, and then ordered her to get out of bed and fetch him a beer! That happened about a week before we came up last time. They had a bad fight and Wendy broke up with him and was venting, you know. And me, I was upset just then ‘cause my boobs were so small. A boy—you remember Raymond?”
“Yeah. I didn’t much like him."
“He was such an asshole. Anyway, he took me on a date and kinda felt me up and told me I should join the itty-bitty-titty club. And so when Wendy was telling me about her asshole boyfriend, I went on about how upset Raymond made me about my bitty titties. So Wendy said, ‘Let’s have a look at ‘em.’”
“Where were you?”
“Here in the Shack. Wendy had a bottle of white wine, and I had one glass and she had a couple. You and gruncle Ford were off somewhere, the place was already closed for the evening, and Soos and Melody had taken Abuelita and their kids into town for dinner and a movie. We were down in the parlor. We took off our tops, and Wendy said for my height I had about as much as she did, but really, she’s bigger. Was bigger, I mean, not now. I told her that her boobs were pretty. She kinda felt me up, and I nuzzled her and then I was sucking on her nips. We went on from there.”
“How far, uh, did you two go?” Dipper asked.
“No pussy licking,” Mabel said. “I would’ve, but I think she held back because, you know, I was younger. But we fingered each other until we got off. She said she’d been needing that. Funny, she’s not as good as you! Anyway, she was good enough. Later she sort of apologized and I said I had a great time, and we should do it again.”
“Did you?” Dipper asked.
“Couple of times. Wen said that she and Tambry used to ease each other’s frustrations—that’s what she called it—when they were still in school. Later in the summer she took me to this swimming hole in the creek, a spot that's kinda hard to get to but really pretty, and we went skinny-dipping and she’d brought a couple of vibes, and she did me and I did her and we got each other off. Then one more time we kissed and cuddled until she broke it off. I asked her what was wrong, and she said she shouldn’t be doing stuff like that with me, she should be doing it with you, but she cried a little bit and said she blew it, 'cause you two had promised just to be friends. I'm telling you now because I want you to know she's willing.”
Oh, so that was why Wendy had started flirting with him that summer. And later came the sexting and the pictures.
Dipper took a deep, deep breath. “Mabel, if Wendy really wants to—you know? I mean a threesome?”
“Totally up to you, brobro,” Mabel said, putting her hand on his cheek. “I’m down with it. And look here, you’re getting yourself up again! How many boners can you get in one day?”
“When Wendy and I are fooling around on the phone,” he said, “maybe three in a row.”
“Gotta gat that up to three every day for each of us,” Mabel murmured. “That should be enough.”
“I still don’t know,” Dipper said. “I mean, I love the way this feels, but the thought of you and me . . . “
“Fucking,” Mabel said comfortably. “I'm like Wendy. We don’t mind if you say it out loud.”
“I still feel creepy about that,” Dipper said. “Um—if you and me and Wendy, you know, would it be okay with you if you and Wendy did lesbian-type things, and I just fucked her? Not you? Damn it, I can’t say it right.”
“Dipper, Dipper, this is me, Mabel. If Wendy wants me to eat her out, or if she wants to go down on me while you’ve got your dick inside her—whoops, you’re twitching again! I’ll keep whatever boundaries the two of you set, okay? But if you’d like me and her to go down on you, then that’s fine with me, as long as I get off somehow, too. I mean, Wendy could do me, or you could use the vibe on me or even finger me off again. What I’m saying, is if at the end of the day we’re all satisfied, that’s all I ask.”
“Then I guess we’ve got a deal.”
“Yeah, and we still have until next Friday for you and me to polish up our techniques.” Mabel hooked her leg over Dipper’s and pressed against him. “Speaking of which, brobro, I know I can cum more than you can. Any girl can cum more than any guy. But do you think you might manage to pop just one more time before we have lunch?”
He reached out to caress her breasts. “Yeah, I think so.”
“What would you like to do?” Mabel asked huskily.
“I think I could use more practice with that sixty-nine thing,” Dipper said.
Her smile grew wide and wicked. “Hmm. Yeah, I could go for that. Would you put a vibe in my pussy?”
“Sure,” he said. “I guess so.”
“I got a new one,” she said mischievously.
“Huh? How? I mean, you didn’t hide another one—?”
“Mail order, brobro! You didn’t notice the package on the porch when we came inside a while ago?”
“Uh—no?”
Mabel hopped out of bed. “I have an account with Pleezer! That’s an online toy store for grownups! And I put in a rush order the other night, when we learned we’d be coming up here, and I recognized their logo on the package. BRB!”
“Put on some clothes!” he yelled.
She made a face at him, but pulled his tee shirt over her and then went barefoot down the stairs. He heard the downstairs door open and then close again and lock. Then the stairs creaked.
She came in brandishing a cardboard box with a suggestive logo—the word Pleezer in swashy pink script, but the P had a slant and a suggestive bulge to its stem, making it look like a half-erect dick and balls. “Voila!”
Mabel took off his shirt and then ripped the box open. “Hey, you got any double-A batteries?”
“Uh—used to keep them in the drawer,” he said. “There may be some—”
Mabel jerked the drawer open. “Yep, a twelve-pack, still about half of them left.” She scrabbled two out of the drawer and then ripped the package open and turned her back to him as she muttered to herself, “This unscrews . . . positive, negative, got it. I think I’m gonna like this. How’s my ass look, Dip? I know you’re staring at it!”
“Very shapely,” he said honestly. She tossed something to him, and he fielded it one-handed. “What is this—oh, the lube?”
“The KIS lube,” she confirmed, jumping back onto the bed. “And I’m gonna need this. Here’s your weapon!”
He took the vibrator and frowned at it. “Exactly how does this—”
“The bigger one with the curved tip goes in my pussy, dum-dum,” she said with glee. “And you can guess where the smaller one goes.”
It was a forked vibrator. Dipper said, “Um, in your butt?”
“See, you’re brilliant! But I haven’t tried anything in my back door yet, so don’t put it in until I tell you.”
She swung a leg over his chest, straddled him, and grabbed his stiffening dick. “Mabel—”
“Sh, sh. Don’t talk. I’m gonna suck you again. You don’t talk, just use that tongue to get my pussy nice and ready. And squirt that lube all over my butthole! Remember, KIS is mouth-friendly, so don’t worry about any drippage—get busy. And then when I say give it to me—”
“I stick it in both places,” Dipper said.
“Pussy and ass,” she said comfortably. “Start licking! Ohh, yeah. You got talents, Dip—and—” she bent and gave his dick a smacking kiss—“so does your sis!”
Mabel was so ready for sex that she made it difficult for Dipper to concentrate. But he used lots of saliva and when Mabel interrupted her enthusiastic blowjob to gasp “Ass lube!” he squeezed the bottle and sent a spurt of minty-flavored, tingly gel lube right on target. “Finger first!” Mabel ordered. “I’m gonna keep you from cumming until I get the vibe in me!”
He pressed his index finer against her puckered asshole, and after a moment the tip glided in. While he did that, he sucked and tongue-lashed her clit. “Mmnnghh!” she moaned. “Whoo! I'm R-r-ready! Put it in! Sl-slow at first!”
The slightly crooked blunter tip pressed into her pussy without much resistance. It wasn’t as thick as Dipper’s dick, and it glided in easily. Then the narrower butt probe pressed against Mabel’s sphincter. “Yeah,” she said. “I'm relaxing everything back there! Put it innnnn . . . and then turn it on!”
When Mabel was, so to speak, forked, one prong in her butthole, another in her pussy, Dipper switched on the vibe. He just had to hold it in place. She started pumping her hips, fucking the toy. “Wanna cum together,” she said, her voice strained from pleasure. “Ride me with that thing! Rock it so I can feel it in both places, yeah, like that! Cum for me, Dipper! Shoot it into my mouth!”
It was hard to hold back, and Mabel’s sudden twitching, clenching orgasm triggered his own. He felt her mouth welcoming the spurts of cum and felt the waves of her ecstasy reeding as the peak passed. “Gloop,” she said. She swallowed. “Good! I’m gonna learn to deep-throat your cock yet! Let me get some more.’
She sucked more semen from his dick, then rolled onto her back. He reached to remove the vibe, but she gripped his wrist. “Nh-uh!”
So he lay beside her. She smiled at him with chipmunk cheeks. “Are you still holding some inside your mouth?” he asked.
She nodded happily. After lying there and humming with closed mouth for a minute, she switched off the vibe and pulled it out of her butt and pussy. She swallowed with a gulp. “Mm-mm! Best fifty dollars I ever spent!” she said. “What a ride!”
“Why did you keep my cum in—”
“Cause I like the kinda peppery taste! And the longer I hold it on my tongue, the spicier and nicer it feels and tastes. Wanna go again?”
“Oh, God, no. I couldn’t.”
“Later, then,” Mabel said. She turned on her side. “Rest your cock in my crack, brobro. And give my titties a rubdown. They’re all tingly.”
“This is just to get me hard again,” he said as he started to do as she had asked.
“You got it,” she said comfortably.
