16. Getting Adjusted
In mid-April, Dipper was waiting for Wendy to come home from work when Mabel called him one Friday evening. “Hi, Brobro,” she said, not in her usual frantic manner but sort of soft and low. “What are you doing?”
“Marinating a steak,” he said. “Wendy and I are gonna cook out for dinner.”
“Oh.” She paused. “Guess what I’m doing right now.”
“It sounds like you’re flying a remote-control drone,” Dipper said. He could hear a hum.
“No.” She whispered: “I’m masturbating! With a vibrator! Here I am in my apartment, lying on the sofa, with nothing on at all, one leg on the floor, the other hooked over the back of the sofa. And I’m holding this little buzzer and using it to play with my clitty. It’s made me so wet, and I’m just about to slip it inside me. Feels so good. And there it goes. Almost fills me up. Hey, I miss you, Dipper.”
“Uh, I miss you, too, Sis. But I think not exactly in that same way.”
Mabel giggled. “I know, twincest squicks you. Oh, God, I ought to do this more often, it’s fantastic. Don’t worry about me, Dip. It’s okay. I’m flirting with Eileen, a girl in my painting class.”
“Oh,” Dipper said.
“Uh-huh. She broke up with her jerk of a boyfriend before Christmas. I think she may be ready to play on the other team. Anyway, she’s coming over to my apartment tonight for a sleepover, and when we’re in bed, I’ll make my surprise move. Am I evil?”
After a moment of thought, “No,” he said. “I couldn’t call you that without saying that I am, too, and Wendy, Tambry, and Pacifica.”
“Ohh, Pacifica,” Mabel said with a lingering sigh. “Tell her I want to come up to the Falls for spring break, the whole week, and ask her if she and I can, you know, get together.”
“I will,” Dipper said, “but you can call her yourself—are you okay?”
Mabel was moaning. “Uhh,” she said. “Yeah. Thinking of Pacifica, I just made myself come. When did I talk to you last? Did I tell you about my nipples?”
“This is making me uncomfortable,” Dipper said, setting the steak aside on the counter. “We last talked about two weeks back. You didn’t say anything about . . .” He trailed off.
“Yeah, my nips. Or call ‘em my pacifiers. Pazifiers! Ha! Anyway, Wendy told me they’d grow bigger, and they have. They get lots stiffer now when I’m, you know, turned on, and they’re so sensitive. If I’m feeling horny, I even can sit in my car at a red light and rub them and get myself off. Hey, if I embarrassed you with T.M.I, how about this? Now when I really get off, I squirt!”
“You’re right,” Dipper said. “Now I’m twice as embarrassed.”
Mabel giggled again. “I’m cleaning my vibe,” she said, smacking her lips. “I’m licking it. I taste yummy! I’m gonna have my fingers down inside me when Eileen comes over and get them nice and wet and then rub my lips real good and then kiss her on the mouth. And then if she doesn’t pull away, I’ll get a little tongue action going, and it’s all downhill from there. Hey, Brobro, are you still doing everybody?”
“What? No! What?”
“I mean,” Mabel said patiently, “Wendy and Pacifica and Tambry.”
“Yes,” he said. “But not all the time! And not as often when we’re all together in the same place. I mean, Wendy and I are living together, but we usually see Pacifica and Tambry only on the weekends—”
“I like it when Paz bosses me around,” Mabel said. “I never dreamed I’d be a sub, but with her—is it that way with you, Dip?”
“Does she boss me? No.”
“Yeah, I guess Wendy would sock her if she tried to dom you. I hope Eileen's up for girl on girl. She's wanting to move out of the dorm, and it would be great to have a fuckbuddette sharing my apartment. Hey, now that my vibe’s all squeaky clean, I think I can have another orgasm. Gonna give it the old Mabel try, anyway. Listen.”
Dipper heard the buzz, suddenly very loud.
“Did you hear it? I held my vibe up to the phone. Want me to send you a photo of it in action? Or just a picture of me holding it?”
“That would be a no,” he said. “To both.”
“It reminds me of you,” she said. “Nice and thick and pink, with a purple knob on the end. The shaft is fat, and it has this shallow banana curve in it, like your dick. And the tip’s real soft, the rest of it nice and stiff. I wish it was warm, too. Okay, here we go—little bit more lube, that great warming stuff. And now it’s deep diving into Mabel’s tight pussy! It feels really nice, but not real. I loved when Pacifica laid on top of me and I could feel her hard nipples pressing mine, and she had that fancy strap-on buzzing away in my pussy and told me to wrap my legs around her. I, I think I’m gonna hang up, Brobro. I’m busy right now. I’ll call next week!”
“Fine,” Dipper said. He had images in his head that rubbing their custom steak seasoning (smoked paprika, onion powder, a touch of brown sugar, a pinch of cayenne, salt and pepper) did nothing to get rid of. He washed his hands and muttered, “Dammit, Mabel!” he had a hard-on.
Wendy breezed in a few minutes later. “You look sort of flustered,” she said as she set her documents bag down next to the bookcase. She could always read his moods.
“Mabel was on the phone,” he said. “She, uh, she was doing herself with a vibrator while we talked.”
“Aw. She’s still not over you,” Wendy said, smiling. “Poor guy!”
“Maybe she’s getting over me in one way,” Dipper said. “She’s trying to get herself a girlfriend, one of her classmates. You can tell from the way Mabel talks she’s still crushing real strong on Pacifica. Speaking of which, are Pacifica and Tambry coming over this evening?”
Wendy glanced down at the front of Dipper’s pants, which showed his excitement. “Oh, meant to tell you Tam and I talked this afternoon. They want us to come to Pacifica’s. After dinner. Nine-ish, Tambry said. So you and I can unwind first.”
“That sounds so good to me right now” he told her, getting up from the sofa.
She put her forehead against his, looking straight down at his fly. “When will the steak be ready for the grill?”
“Need to let it chill for a while, then bring it out as I start the grill. About an hour altogether,” Dipper said.
Wendy reached down to rub his erection through his khakis. “Then what are we waiting for? We can do a lot in an hour!”
When they had stripped each other and toppled into bed and kissed and caressed, Wendy asked, “What would you like to do, Big Dipper? I’ve been selfish lately. Let this be totally your call. We can do it any old way you want.”
“I really like our sixty-nine sessions,” Dipper said.
Wendy bounced up on her knees. “So do I! Great appetizer before a steak dinner. Me on top or bottom?”
“Top,” Dipper said. “I know how strong you are, but I’m always afraid I’ll smoosh you.”
“I’m unsmooshable, dude. I can go either way,” she teased him.
“No, I like you on top,” Dipper said. “I can pull you down and you can, you know, get to everything easy and take as much or as—”
“Top it is.”
She mounted him backwards and presented him with her orchid-like pink pussy, already wet, and again he noticed how the change in her clit had become permanent. It was a fleshy, salmon-pink marble now, peeking out of its paler sheath, and it begged to be licked. Wendy was so ready that she oozed fluid, which Dipper caught on his tongue and savored as it dripped. She snuggled against him flattening her breasts on his stomach, stroking his hard-on and giving the engorged head some sensuous licks.
Dipper most liked that his enlarged dick now pleased Wendy so much. The other girls, too, but especially her. Changes weren’t necessarily bad!
He knew Wendy felt the same way about her own changes—the increase in her breast size, her stiffer, more erectile nipples, the spurt of fluid whenever she came, and even now and then when the sex was very intense, a flow of sweet, hot milk. And she said her heightened sensitivity had never decreased again. A week before, just for the hell of it, they had driven up to Lookout Point, the local Lovers’ Lane, on a fairly warm, clear starry evening.
She had worn opaque black leggings and a long-tailed man’s plaid shirt. The long shirt was necessary because the leggings, which tightly clung to her legs like a coat of black oil, had no crotch. That was convenient when Dipper pushed the passenger seat rearward for greater legroom, reclined the back, and Wendy pulled up her shirt, grabbed his dick, and guided it in while she sat on him.
She loved it slow. He loved the way her butt cheeks tucked soft against his stomach when they did it on the sofa or on a chair and she was being a reverse cowgirl. They called this particular position the rocking chair, because just gentle back-and-forth movements could keep both of them building up for a long time.
As they heated up, the action became steamy. Often Dipper could get her off just by putting his hands up inside her shirt, where no bra stood between his fingers and her boobs, and pinching and tugging her nipples. Her nipplegasms, as she called them, prepared her for the great big one down below.
That night in the car Dipper was lovingly working her nipples between fingers and thumbs. “God, I love it! Give me more of that,” Wendy moaned, reaching an arm back to ruffle Dipper’s hair.
That was the moment when the dumb deputy sheriff suddenly shined his flashlight in through the passenger window. “What are yall doin outcheer?” he asked in his hick accent.
As Dipper strategically moved his hands from her tits, Wendy calmly rolled the window down a few inches. “We’re just looking at the stars,” she said. “Anything wrong with that?”
“No, but you’re setting on your boyfriend there!”
Because of the long shirt, the deputy couldn’t see that Wendy was milking Dipper with her pussy. Even sitting still atop him, she had become very adept at squeezing and rippling her pussy along his shaft. She said sternly, “Is there a law against sitting on my boyfriend’s lap?”
“Uh—”
She started subtly rocking, and with her left hand she reached down to tickle Dipper’s balls.
“If there’s not a law against it, Officer, how about just letting us look at the sky? We’re not hurting anything. Anyway, we’re astronomers, and I’m looking for the Big Dipper.”
“Uh, it’s right yonder,” the deputy said, pointing.
“Thank you. That’s all.”
The deputy tipped his Mountie hat. “Glad to be of service, Mam.” Wendy rolled the window up.
And about five seconds after he’d driven off in his police car, they’d both orgasmed. “I thought we were dead,” Dipper said, hugging her, reaching down to her clit and stroking it as his cum and her juices leaked out.
“You feel pretty lively inside me there,” Wendy said comfortably. “You’re still hard, man! I’m glad we put the towels on the seat, though. That kinda got me hot, doing it in public and him not noticing. Where can we go this summer? We could stand out in the lake and fuck underwater, maybe!”
She was rocking again, and Dipper thought he would be able to come one more time. He continued massaging her clit with his right hand and reached up to her nipples, drippy nips now, with his left. “Or we could get a pickup with monster wheels and do it in the truck bed while we’re in a parking lot somewhere.”
“Oh, or in the high school! I’d love to do it in the principal’s office chair while he’s not there!”
Or get a group of Pacifica’s many, many friends and let her rent a theater and they could even do it on stage with an audience.
“Not good,” Wendy decided. “They’d all be girls, and they’d all want to fuck you—yeah, right there, you know what I—unhh! Hang on, I’ll make you cum, too, just—let—yeahhh—me ride this one out. Ready for high gear?”
To his surprise, Dipper thought that nearly getting caught had spurred both of them to a second throbbing, moaning climax. Maybe Wendy had something there. So many possibilities.
They’d decide later.
But right now, in their bed, his mouth to her pussy and her mouth pumping his dick, he couldn’t think about anything else. Wendy was nude on top of him, her spread slit pressed against his tongue, and she was happily, deeply sucking his dick, thirsty for cum, and he was tongue-fucking her. They’d become so accustomed to each other’s reactions that he knew just when and where to place a finger the moment he was ready to shoot. They both came at the same moment, she gushing her oddly tangy, fizzy ejaculation liquid and he shooting a load of hot cum into her mouth as she gulped.
“Nice appetizer,” she said dreamily when they rolled apart and lay head to head again. “Oh, hey, I forgot to tell you earlier. Tambry said Pacifica’s got some kind of contest in mind for tonight. Hope you’re feeling up to it.”
“What is it?” Dipper asked cautiously.
“I don’t know,” Wendy said. “But I’ll bet it will be sexy.”
“I sort of figured,” he said.
As it turned out, it was a race to the finish. Pacifica bet that she could out-last Wendy and Tambry in a muff-diving contest. Dipper was the judge. He felt kind of out of it, but he gamely held the stopwatch as first Wendy went down on Tambry and made her squirt in one minute and eleven seconds.
Then they traded places and Tambry couldn’t make Wendy cum until two minutes and a half had passed.
“So I do the winner,” Pacifica said.
Tambry distracted Dipper by fondling his dick as he timed Wendy’s eating out Pacifica. The blonde girl resisted, but she squirted at two minutes and thirty seconds, tying Wendy.
“So this is for all the money, Lumberjill” Pacifica grinned as Wendy lay on her back and held her pussy open with two fingers.
“Bring it on, Rich Bitch,” Wendy said.
And this time Wendy came in two minutes and three seconds. “I win!” Pacifica announced, her lips and cheeks glistening.
“Pacifica gets her wish!” Tambry said.
“Goddam it,” Wendy said, but good naturedly. “I fucking hate to lose!”
“Don’t let Dipper cum!” Pacifica warned.
“Just keeping him hard,” Tambry said.
With a smirk, Pacifica said, “So I’m the winner, and I say that my prize is watching Dipper take Wendy’s anal virginity.”
“Hey, wait,” Dipper said.
“She won, Dip,” Wendy said. “A deal’s a deal. But please lube up real good. I’ve never done this before—at least not with a dick—and I’m a little scared of that thing.”
“Put a vibe in your pussy at the same time and it’s like the best ever!” Tambry said.
“Yeah,” Pacifica agreed. “Dipper’s not gonna hurt you, Wen. But I want to see this!”
Wendy lay across Dipper’s knees for the obligatory enema. “I never had one of these before, either,” she said. They were in Pacifica’s enormous shower stall, half as big as Dipper’s attic bedroom, and he sat on a shower chair. A snickering Tambry plugged the nozzle in and slowly squeezed the big red bulb, filling Wendy with a warm solution called Tushy Flushy—Pacifica knew where to buy the weirdest sex toys.
“I can feel it in my stomach,” Wendy said.
“Okay,” Tambry said. “You’re full. I’m gonna pull this out. Pacifica, you ready?”
“Ready!”
“Wendy, squeeze your butthole tight. You’re gonna have to make it to the toilet to get rid of this stuff.”
“All right—what the hell?”
“It’s a butt plug!” Pacifica said. “I just popped it in. It’ll keep you from leaking on my bathroom floor.”
“Damn, this thing’s big!”
“His is bigger. Help her up, Dipper. Go, Wendy! And be sure to use the bidet after!”
“Ever seen your girlfriend on the toilet?” Tambry asked Dipper.
“Actually, yes,” he said. They had few inhibitions left any longer.
Wendy got to the toilet, reached back, and pulled out the plug. It was hot pink, shaped like a big, fat teardrop, with a ring on the back. She sat and Dipper heard the rush of the fluid being shot into the bowl. Pacifica daintily took the butt plug and dropped it into a clear jar of soapy water. “I’ll wash it later,” she said. “Take a quick shower to rinse everything and then finish down there with the bidet.”
Pacifica’s bidet, imported from France, looked sort of like a backward toilet. Wendy had used it before, but she flinched a little as the water began to fountain. “Cold!” she said. She looked Dipper in the eye and said, “You better make this worth it, man!”
Tambry, who was idly stroking Dipper’s huge erection, said, “We’ll make sure you like it, Wen!”
For the occasion, Pacifica had Wendy sit in what she called her sex chair—just an ordinary chair, but without arms, and capable of reclining. Wendy lay back and Pacifica adjusted the chair until the redhead’s butt was tilted back. “Raise your hips,” the blonde ordered, and when Wendy did, Pacifica lubed up another butt plug. “This will loosen you,” she said. “Push back as I start easing this in.”
“It’s big,” Wendy said, but gradually she relaxed as the bulb popped in.
“Now,” Tambry said, brandishing a big penis-shaped vibe, “I’m gonna get you cranked way up, but tell me if you’re getting close to cumming, and I’ll ease off until Dipper’s ready to slip his plug inside you instead of that one!”
“He’s ready now,” Pacifica said with a glance at Dipper’s cock. She was kneeling on some cushions to watch Tambry tantalize her best friend with the vibe, and she had Dipper stand behind her. She encouraged him to rest his dick on her shoulder, and now and then she nuzzled it with her cheek while also gently stroking him, keeping his motor running.
“I can’t take this very long!” Wendy groaned at last.
“Okay,” Pacifica said. “Dipper’s gonna lay on his back and you’ll put him into your butt. Tam’s gonna keep working at your pussy, and I’ll come over and let you suck my boobs and finger my pussy.”
Dipper lay back while Pacifica generously lubed him up. Then Wendy straddled him and Pacifica pulled out the plug—leaving Wendy’s opening gaping. “Dipper, hold your dick steady for me,” Wendy said.
He took hold of his shaft as she carefully lowered herself. Tambry moved slightly to the side and leaned to watch as his swollen tip pressed against Wendy’s asshole. “He’s done me three times,” Tambry said in an encouraging voice. “He knows how to do it. More lube? Squirt them, Paz!”
Pacifica obligingly knelt in front of Wendy, her knees tight against Dipper’s thighs, and Wendy put her hands on Pacifica’s shoulders, steadying herself as she slowly impaled herself. Dipper felt the stream of lube hit his shaft and drip from Wendy’s pussy and bottom. “It’s in,” he said. “Just the head.”
“Feels so big,” Wendy said. She forced herself a little lower.
Tambry reminded her, “Remember, this is the opposite of regular fucking. Move up fast, but move down slow!”
“I can take a little more,” Wendy said. She did—a little more than half Dipper’s length—and then Pacifica pressed her tits against Wendy’s face, Tambry got behind both of them, and the brunette reached through both Pacifica’s and Wendy’s outspread legs to bury the long vibrator she held in Wendy’s pussy.
“Are you good, Wendy?” Dipper asked.
“Y-yeah, it feels fucking wonderful. You?”
“Real snug, but I can feel the vibe!”
“Okay, man, here we go.”
“Don’t forget my tits,” Pacifica said primly.
Then Wendy fingered Pacifica and sucked her tits, Dipper fucked Wendy’s ass, Tambry dildo-fucked Wendy with the vibe, and Tambry . . . also fingered herself at the same time.
It didn’t last long. Wendy yelped as she had her orgasm, Dipper came in her butt, Pacifica laughed and said, “Now I want some action!”
“Ohh,” Wendy said, rising as Dipper’s cum drooled out of her butt. “That was . . . something else!”
“Yeah, you liked it, didn’t you?” Tambry asked as she helped Wendy stand.
“I liked it, but I don’t know. It’s a lot to take. Maybe save it for special occasions.”
“Dipper, can you fuck me?” Pacifica asked.
“Not until I rest!”
“I’ll do you with the strap-on!” Tambry said.
Pacifica grinned. “Get into it! Wendy—?”
“Gonna lay out this time,” Wendy said. “Me and Dipper will cheer you guys on.”
It wasn’t a prolonged orgy that evening. Afterward, they had a little wine, they sacked out in Pacifica’s oversized bed, and in the middle of the night someone woke Dipper by slipping his already-erect dick in her pussy and riding him. He fucked until he came again, and only when he woke again in the morning did he realize he didn’t know which girl it was.
He asked Wendy later that day as they drove back to her house, and she just grinned at him. “Who do you think it was?” she asked.
“Well—she was tight at first, and she bounced more than you normally do. I’d guess Pacifica.”
“Good guess,” Wendy said.
“Were you even awake?” he asked. “It was like two in the morning.”
“Yeah, Tambry and I were awake, and we knew exactly what Paz was doing, but we were afraid we’d start giggling and spoil it. So we muffled our voices by going down on each other.”
“Oh. Is, uh, sixty-nine better with a girl or—”
“Better with you, dork!” Wendy said. “I love Tambry to pieces, but she can’t give me what you do—a great big mouthful of delicious cum!”
“Good to know,” he said. “That’s very good to know.”
