Wendy and Tambry had to help hold Pacifica down for her first time. Mabel had donned the strap-on that she’d named Mr. Bouncy Bouncy. One of its double dildos fitted snug in her pussy, the other one bobbed, ready to go to work.
Pacifica, though she had been made to cum three or four times, still was skittish about taking the dildo in her pussy. So Wendy knelt behind her head and pressed her shoulders down, and Tambry had one arm hooked under Pacifica's thigh and fingered her pussy until Mabel said “Ready and lubed!”
“She’s juiced up too,” Tambry said. She held Pacifica’s left thigh while Mabel pushed her right to the side. Grasping the bobbing dildo, Mabel reached to caress Pacifica’s vulva and to tweak her butt plug.
“Ready or not,” Mabel sang.
Pacifica stopped squirming. Her voice sounded frightened but oddly eager. “Please. Why are you doing this?”
“Because you want me to,” Mabel said quietly. “You do want me to. You do. Don’t you?”
“What’s wrong with me?” Pacifica asked.
“Nothing. You’re naked and beautiful and sexy as hell, and you want to do everything I say. Come on, you’ll love it. You’re more than ready.”
“I want it, but I—I’m scared!” Pacifica whined.
“Yeah, but horny as fuck,” Mabel said. “You want this.”
I, I. I w-want it,” whimpered Pacifica. “Don’t hurt me.”
“You want me to put it inside you and fuck you,” Mabel suggested.
Softly pleading, Pacifica said, “Just don’t hurt me. I’ve never done this.”
Mabel chuckled. “You’ll do it a lot from now on! You won’t be able to get enough of it. Your pussy is so wet! Okay, this is the head. I’m rubbing it up and down in your slit. You feel it? You must—you’re dripping down here. Tell me to put it in.”
Pacifica lay back, her hands clenched on the sides of the air mattress she lay on. Her eyes were closed and her face and upper chest glowed pink. “Okay,” she whispered.
Mabel said to Wendy, “I got this now. You girls go have fun.”
Wendy and Tambry backed off, knee-walking to the next mattress, where they began to kiss and cuddle. As she embraced her friend, Wendy whispered in her ear, “When did we get to be subs?”
“Mabel did something to us,” Tambry groaned. “Put your fingers in my pussy.”
“Do mine at the same time.”
Though they began to writhe with yet another building orgasm, Tambry and Wendy couldn’t take their eyes off what Mabel was doing with Pacifica. Around them Tiffany, Marci, and Candy had somehow contorted themselves into a sucking, stroking, gasping pile. It was hard to tell who was doing what to who.
Still, the main show was Mabel and Pacifica. “No,” Mabel was crooning. “I want to do it, but you have to ask me. And ask me nicely and do it right.”
Moaning, Pacifica said, “Dipper, p-please f-fuck me. I want you to put your, your thing in me.”
“Aw, don’t be all prissy-pissy,” Mabel said. “'Thing?' Really? What is this I’m rubbing here? What's this pretty pink slit that's already got the head inside it? Tell me. Use the words.”
“It’s m-my vagi—”
“Use the words,” Mabel warned.
Pacifica bit her lip and then said, “It’s my cunt.”
“And what do you want Dipper to do to your cunt?”
“Want her to stick her dick in my cunt. Please!”
“Dipper’s a guy,” Mabel reminded her.
“Mabel, I mean Dipper, please, stick your dick in my cunt and make me cum. I need it so bad!”
“Make it romantic and ask me nicely and use the right name, and I’ll do it.”
Taking a deep breath and looking Mabel straight in the eyes, Pacifica cooed, “Dipper, I want you. Please put your dick deep in my cunt and fuck me until I cum.”
“Yeahhh,” Mabel said. "Good girl. We're both gonna love this. Relax now, let me in." She pushed. Pacifica, who surprisingly seemed to be inexperienced, gasped and momentarily tightened everything up.
Wendy and Tambry were gleaming with sweat, both from their rhythmic efforts to stroke each other off and from the arousing sight of Pacifica begging for it. “Jeezes,” Tambry whispered. “Didn’t she ever use a dildo?”
“Don’t think she ever even fingered herself,” Wendy murmured. She reached way back and grasped Tambry’s butt plug. “I’m gonna take this out and give your asshole a little attention.”
“Ooh, yeah,” Tambry said. “Let me on your lap.”
Wendy, sitting with her legs extended, waited until Tambry had crawled to drape herself over her friend’s thighs. “Mabel gave you her favorite,” Wendy said. “The purple one.” She took the little knob on the plug between her fingers and playfully tugged it and released it. Tambry wriggled her ass. “Take it out. I want to feel your fingers in there. I’ve been so bad tonight,” she said invitingly.
“Yes, you have,” Wendy agreed. “And you know what bad girls get.” She drew back her right hand and gave Tambry’s tawny-colored shapely butt cheek a sharp slap, making it quiver.
“Yeah, spank me!” Tambry said, gasping. “Make my ass glow, and then pull out the plug and do my butthole!”
From experience, Wendy knew that Tambry liked it hard. She didn’t need to be told she was a bad girl. That was just the trigger. What Tambry craved was a good firm spanking, and indeed her ass cheeks began to turn a bright pink as she squirmed and—Wendy was sure—came once just from the repeated loud smacks.
Alicia came over to watch. Candy had set out a big bag full of toys, and Alicia selected a butterfly vibe and used it on herself as her gaze took in the spanking that Wendy was administering. She came, spurting, and then crawled over to the box and rummaged through it. She dug out a set of anal beads and came and shyly held them out. "Uh, maybe you two would like these?"
"Thanks," Wendy said. "This is just the kind of thing that Tambry likes!"
There might have been more, but just then Tiffany called out to Alicia. "We're making a daisy chain!" Alicia rushed over to join in.
Meanwhile, Mabel, poised for the grand entrance, said to Pacifica, “Here we go. All the way in. Oops, what was that?”
“It hurt,” Pacifica whimpered.
“Want me to stop?”
“N-No, fuck me!”
“I think I just popped your cherry, girl! Little surprise that you still have it, after all those ponies you used to ride. Well, too late to worry about that now.”
As Mabel started to fuck her, Pacifica yipped a little: “It hurts. It hurts.”
But then she started to pump her hips. Soon she even wrapped her pale white legs around Mabel and locked her ankles. And then she was into the movement, grinding and gasping.
“Now it feels good,” Mabel said. “Tell me.”
“Oh, Ma—Dipper, it feels so good! Fuck me deeper! Harder!”
“You got it.”
Mabel pressed down and crushed her mouth against Pacifica’s. Pacifica tongued her desperately, and Mabel felt rather than heard the blonde girl humming urgently into her mouth.
She could read the signs. Pacifica’s erect nipples had jutted out nearly an inch long, but now they seemed to shrink—not because they were losing their erections, but because the areolas had swollen pink and puffy to partly cover the engorged nipples. A rosy flush had spread from Pacifica’s neck down to her upper chest and was invading her tits.
“You’re gonna cum,” Mabel teased, increasing her speed as she fucked Pacifica. “You're getting close! Feel it? Feel it? Tell me. Yell my name when it hits you!”
“Ahh God!” Pacifica said, her whole body clenching. “Mabel! Mabel!” She gasped and then with another ecstatic spasm, she screamed, “Dipper!”
Mabel released her after a few seconds. “How was that?”
Meekly, Pacifica said, “I love you, Mabel.”
“Yeah, well, I’ll be Dipper for you whenever you want. Oops. We made a mess. Hey, Candy! Towels!”
“Yes, I bring them!” Candy disentangled herself from Tiffany and brought over a couple of towels.
“Wet one,” Mabel said. “Good. Now clean up Pacifica’s pussy and bottom and the air mattress. Pat everything dry with the other towel." Mabel sat, and Pacifica came and leaned against ther. Mabel reached around to fondle her boobs. "You did good, girl. Still hurting, Pacifica?”
“Not much,” Pacifica said. “It felt so good. Can we do it again?”
“Sure, but we don’t have to do it the same way,” Mabel said. “Let your tender place rest. But we can still get each other off. How’s the clean-up, Candy?”
“All finished! Red all gone!”
Grinning, Mabel asked, “You said something about a rim job, I think?”
Candy perked up. “Yes, I love to do them. May I?”
“Pacifica, roll over. Get on your knees. Spread your thighs a little. Little more. Good. You want to eat me out after that, don’t you? See, I didn’t get to cum. You can make me cum if that would make you happy.”
Pacifica eagerly nodded. “I’d like to.”
“Now, Candy’s gonna do wonderful things to your butt. If you like licking my clit and pushing this into my pussy—” she held up one end of the strap-on—“then Candy’s going to make you cum in a different way. You’ll love it. So what do you want to do?”
“Eat you out and put that, uh, thing in your cunt and make you cum.”
“It's not a thing, it's a dildo. Or when I'm wearing it, it's a strap-on. Now let Candy make you feel good.”
“Yes. Can we start? Please?”
Mabel affectionately patted Pacifica’s head. “What a good lover you are. Okay, Candy, take out the plug.”
Pacifica blinked as Candy tugged her butt plug util it popped out. “Ooh. I didn’t think that would feel good!”
Mabel said, “Candy, do your thing. Pacifica, look at me until I tell you to start. Not my pussy, my eyes are up here. I just want to watch your face.”
Pacifica nodded and gazed up adoringly at Mabel. Then her eyes widened and she twitched. “She’s—her tongue is going inside—ooh! This is—it’s dirty—”
“But—?” coaxed Mabel.
“But I love it! Let me suck your clit, Mabel, please!”
“Okay, start with that. Then when I tap your head, like this—” a light tap—“put the dildo in my pussy and fuck me with it. And I think when I cum, you're gonna cum, too. Candy, you can use your fingers in her pussy, but be gentle, she’s barely broken in.”
Nearby Tambry lay on her back, her knees drawn up, her legs spread. Wendy had been kissing her upside-down. The girls were doing one of their favorite tricks—they called it mirror loving. Wendy slowly kissed and nibbled her way downwards. Meanwhile everything that she did to Tambry’s body, Tambry did to hers—when Wendy nipped the base of her neck, she felt Tambry’s teeth return the favor on the base of hers. If they did it right, they had matching red love-bites to show the next day.
Then Wendy moved down, and Tambry moved up, to tease and suck nipples, eager brown ones and taut coral-colored ones. It was exciting. It felt almost as if each of them had a double body. What one gave to the other, she also received. They moved slowly, building the excitement, because waiting further along was the alluring gently domed belly, the luscious dry well of the navel, the tempting ascent of the love mound, and then the plunge into the happy slippery tingling valley.
Tambry was as sensuous and as eager as she had ever been in high school. And though thoughts of Dipper flashed through Wendy’s mind, she just couldn’t focus long enough on him to feel any guilt or reluctance.
Pleasure claimed all of her attention.

Dipper got the text late—he’d been searching all over town. The puvlic pool, huh? That could only mean the public swimming pool where he’d briefly worked as an assistant lifeguard, reporting to Wendy. He had checked his phone way over at the youth center, a twenty-minute walk from the pool.
It was starting to get dark. The sun had just set, and the sky was salmon-colored with twilight. Striding through town, Dipper told himself, “Mabel must have freaked out again, the way she did in the convenience store with that dip candy. Except she’s done it now with a love potion. And she’s hooked Wendy into taking it, I think. I’m so pissed at her right now.”
Down the drive, and ahead lay the pool with its tall privacy fence. A pink convertible and a few other cars were parked in the lot. "Pacifica, too," Dipper muttered. Inside the enclosure the lights were already on and provocative moans and yells drifted out. The gate was locked, from inside.
But Dipper had learned a few tricks from his grunkle Stanley. He took out his Boy Scout knife and slipped the blade through the crack in the gate. It didn’t seem to be locked, really, but inside a metal latch had been flicked down into a hasp to hold it closed. Patiently, Dipper manipulated the knife.
“Easy, easy,” he told himself. Then “Got it. Just have to flip this up—”
A snick of the knifeblade swiveled the latch, and it clicked as he tugged the gate open an inch or two.
He peeked through the crack he’d opened.
“Worse than I thought. It’s—she’s got an orgy going on in—oh, no, Wendy! She’s in a chair, and Pacifica’s eating her out and fucking her with a dildo, and she looks like she loves it. Damn. OK. Gotta do this.”
He took something out of his pocket.
“Go,” he said.
The girls had utterly abandoned themselves to pleasure. They writhed, they screamed in ecstasy, they explored each other’s mouths and pussies and assholes. They used eager tongues and daring fingers, they had an assortment of vibrating toys and plain dildos, they were all glowing with repeated orgasms. He recognized Tiffany and Alicia, though he didn't know their names, and he'd seen the others around town. Good God, what was Candy doing with that other girl? She had her whole hand inside!
Sex scented the air. The orgy had absorbed them all, they were all so into it, pussies grinding pussies, tongues all over other girls, orgasms erupting like geysers in Yellowstone, that they focused only on each other.
Then someone just inside the gate yelled loudly, “What the heck is going on here?”
The voice startled them. They all paused and looked around.
Mabel, who had been enjoying the attentions of Tiffany, Marci, and Alicia all at once, rose up on her elbows. “Dipper!” she yelled, rolling her eyes. He stood glaring at her. Mabel stood as the other girls pulled back from her. Shaking her finger, she said, “I might have expected you’d come along to ruin it all!”
He made an angry chopping gesture “Mabel, I don’t care what you do in your private life, but Wendy’s coming home with me.”
“D-Dipper . . .” moaned Wendy as Pacifica, not even bothering to look at the intruder, used a humming vibe to fuck the redhead as she simultaneously stuck a finger deep to her asshole. “Ung! N-no, please, stop that, Pacifica. Dipper, I’m so sorry . . . can’t help it—”
“Girls!” Mabel shouted. “Get him! Tear off his clothes. Initiate him!”
“Hey, stay away from me!” Dipper yelled.
But all the other girls, like predatory cats, crept toward him on hands and knees, grinning, licking their lips, their breasts swinging. Even Pacifica broke free from servicing Wendy and began to crawl toward him, murmuring, “Dipperrrr, Dipperrrr.”
“You, too, Wendy!” Mabel ordered.
Wendy didn’t crawl, but stood and walked toward Dipper, hands stretched out toward him imploringly. Pacifica had left the vibe in her pussy. Grotesquely, it fell out as she took a step and buzzed around and around in a circle, like a cat chasing its tail.
“Come on, dude, you’ll love it,” Tambry, who was leading the crawling pack, cooed.
"It doesn't hurt," Pacifica assured him. "Let's fuck, please."
His back flattened against the fence. “Stay back. You girls don’t know what you’re doing!”
“We know!” Candy said. “Just once I want to taste your dick!”
“If we ask nice, Mabel will let you fuck me,” Pacifica said. They crowded close, reaching for him.
“Wendy,” Dipper said. “Are you going to do this?”
“Have to,” she said. Tears were on her cheeks. “Dipper, please, it’s not all that bad, you'll like it. Just jump in the pool and join us. You can have any of us. All of us. Please.”
“Let go of me!” Dipper said.
Not just to Wendy. The naked girls were ripping his shirt off. They wrestled him to the ground.
Great. This was the kind of situation he’d fantasized when he was a younger teen—being buried in naked, writhing females, breasts and mouths and grasping hands and long soft thighs and mysterious pussies, some bare, some thatched blonde or brunette, all within reach and all eager—
They didn’t even remove his jeans, but just ripped them, tearing the tough material down both legs, even tearing into the reinforced crotch seam, and they peeled off the rags. Candy wrestled off his shoes, Pacifica his socks. Pushing and shoving the others aside, Candy then said, “Let me, let me!” And with hands and teeth, she ripped off his shorts. “Dick! Dick!” she said in a tight voice. “I want dick! Make it big for Candy!”
“Ladies, throw him in!” Mabel ordered.
As they carried him squirming past her—Wendy was holding his shoulders and whispering, “I’m so sorry!”—he glared at Mabel. "Don't do this to me!"
Mabel grinned and said, “This is for your own good, Dipper. A few minutes in the water and you’ll even fuck me!”
He wasn’t struggling any longer. Just stretched still and naked in the grasp of the girls, he looked her right in the eyes. “No, I won’t.” he said. The girls laughed, swung him once, swung him twice.
And they tossed him into the water.
