AVAVA
( Pacifica Northwest )
VAVAV
Pacifica shivered as the air-conditioner kicked on, and covered her nude body in cold air, she stretched before pulling the blanket over her body as she lounged on the bed at a hotel. Not one of the best hotels that she had been to. Not even close. But it was one of the best ones available in Gravity Falls. Under normal circumstances she wouldn't even be here at all.
A Northwest, in a shabby hotel?
That was unheard of.
Then again, given the reason she was there... she doubted her mother and father would take kindly to that situation.
“Ready Paz?” A feminine voice called from the bathroom. Pacifica's mouth started salivating as the brunette girl stepped out of the bathroom, completely naked.
Pacifica allowed her eyes to roam over the other female. Creamy white skin, without blemishes. Perky B Cup breasts, flat stomach. Her eyes finally stopped between the other girls legs. Completely shaven, glistening, pink slit. She watched as the other female's modest breasts bounced with each step towards the bed.
Her parents would not approve.
“Oh yeah. I'm ready Mabel.” Yes, Mabel Pines.
Pacifica was naked.
In bed.
In a hotel.
Waiting for Mabel Pines... and...
“Not gonna wait for me?” The male voice called from the bathroom, that Mabel had just left.
The brunet male that followed, bore a striking resemblance to Mabel. If you didn't count the flat chest, and the, in her opinion, seemingly impressive member between his legs, that was already standing at half attention. This was Dipper Pines, Mabel's twin brother.
Yep. Waiting for the Mystery Twins.
There was no mystery about what these twins wanted.
They wanted her.
And it seemed.
They were very good with sharing.
“Of course not Bro-Bro.” Mabel turned to face her brother, wrapping her arms about his slightly taller shoulders. An act that wouldn't normally be sexual. However, the fact that they were both naked, and watching him stiffen more, as her lips made contact with his. It really made her wonder, just how long these twins had been sharing.
“And here I thought that you were going to get greedy and keep her all to yourself.” He leaned down and kissed Mabel's collarbone.
“We both agreed to share Pacifica. Who eagerly agreed to some fun sexy time. Even paid us, and for the room,” She felt herself heat up as both twins turned to look at her.
“So... Uh... Where should we start?” Pacifica asked, as her eyes wandered over their bodies more. Couldn't stop the little moan that escaped her lips as Mabel bottom jiggled as the girl laughed. And felt her sex quiver as she stared at Dipper's, now, rigid member.
Jesus, it looked big.
Then again, she was a virgin.
So, she wasn't exactly sure what a normal penis looked like. All she knew, was that his... looked too big for the entrance she had between her legs. But looks can be deceiving. She wasn't naïve, she had seen porno, and now that she thought about it, Dipper could rival most of the guys in them... except the obviously, insanely, large ones.
“Is this your first time?” Dipper asked, standing behind his sister, who now seemed to be chewing her bottom lip, as her brother gingerly rubbed his hands across her stomach.
“Yeah, I'm a virgin.” She couldn't help but wonder if Mabel was biting her lip, because of the hand, or if something was touching her back. Or both.
“So, you've never done anything?” Mabel asked, no longer biting her lip, “Not a hand job? No blow jobs? Not even up the butt?” Pacifica shook her head on all accounts, and she couldn't quite understand the last part. What did her butt have to do with anything? “Whoa, how's that happen? I mean Dipping Sauce and I, have been doing it like bunnies since we first came to Gravity Falls.”
“Just... never happened I guess. What do you mean, 'up the butt'?” Pacifica inquired, looking at the other female.
“You know, your butt.” Mabel just looked at her, “Well, if you don't got condoms, which is the key to the front door, you gotta use the back door.”
“So... you want to get right to it? Or want to see how it's done?” Dipper asked, before leaning forward to kiss his sisters neck.
Wow. Not very shy are they, Pacifica wondered watching the twins, who were pretty much telling her, she could watch them screw, before it was her turn.
She was a little ashamed to admit it, but she was pretty turned on thinking about watching them have sex. That was one of the reasons, she agreed to this whole ordeal, was to actually see, Dipper and Mabel doing it.
“Maybe it'll help?” Pacifica said in a tiny squeaky voice.
“So? Paz 'ol girl. Whatcha wanna see me and Broseph here do? Want me to suck'em off? Or up the butt? Or full on vag action?”
“A-All... maybe?” Pacifica couldn't hide her perverted wants anymore.
“All, huh?” Mabel looked over to her male copy, with a coy grin on her face. “You 'up' for that Broseph?”
“Oh I'm 'up',” He smirked putting his hands on her shoulders, and pushing her down to her knees, “The question is; are you 'down' for it?”
Mabel giggled a bit at their little word play, 'tit for tat', before pressing her lips against Dipper's member, her slender fingers running up his thighs before settling on his bottom. Pacifica didn't know what to think when her pink little tongue darted out, to swirl around Dipper's tip. Up until this very moment, she had been half waiting for the two twins to just say 'Gotcha' and call her sick and twisted. So, either this was really happening. Or they were committed to this joke. Then she watched as the member started sinking into her mouth.
Oh boy.
Not a joke, she thought as she watched Mabel's head bob on Dipper's member. She felt a familiar pull in her stomach, just above her groin as she watched Dipper's hand move to Mabel's head, his fingers running through it. She knew the sheets on the bed were becoming pretty damp, as those slender fingers of Mabel's wrapped around the base of the member in her mouth, and she seemed to be... what was the word... jacking him off, that was it. She was jacking him off, even as she was sucking him.
“It's coming.” Dipper's voice was much more husky than usual. Mabel's only response was to start bobbing her head fast, along with the hand on the base of his member.
Pacifica wondered if she just had an orgasm as she watched Dipper tense up, as Mabel held her head still. The only movement, was Dipper's waist that seemed to be spasming. Dipper groaned as Mabel puller her mouth off the member, looked back at Pacifica and opened her mouth.
“Ahhh!” Mabel then closed her mouth, that was full of cum, and swallowed. “Yum! Tasty as always, Dipster.”
“Anything to please my dear sister,” his hand came down to cup her cheek. “So, did you enjoy the show?”
“I uh... Um... Yeah... a whole... uh lot.” Pacifica's cheeks now had to be the color of cherries.
“Okay, Paz, investors choice.” Mabel stood up, embracing her brother. Investor... oh yeah, she paid for the room, “Butt'a'polosa or Vag-Town?”
“Mabs,” Dipper's hand rests on Mabel's shoulder. “I'm used to you weirdness, I love your weirdness. But maybe, tone it down some. I think it's making Pacifica nervous with your forwardness, uniqueness.”
“Well, if we don't ask what she wants, how'll we do it?” Mabel muttered, semi glaring at her brother. Was it too late to call it off? Pacifica was sure that it was, considering she had just watched Mabel swallow Dipper's semen.
“Um... I Uh... I wanted to see... um... vaginal, but I didn't think to bring any condoms.” Pacifica looked down. She hadn't actually thought about it. She had been to excited about the idea, of a threesome with twins, being her first experience.
“No worries, Mabel's on the pill, we have condoms, but they are reserved for your turn.” Dipper's voice had taken on that huskiness again.
“Mmm hmm, we haven't needed condoms since our first trip here, then I got some 'No Baby Candy'” Mabel grinned from ear to ear.
“They are birthcontrol pills... Mabel... tell me you haven't been eating them like candy again.”
“Nuh uh, not again. I just call them that.” Then Mabel's hand touched his bare chest, “But, enough about that. I think our benefactor just made a request of us. I don't think we can keep her waiting.” Mabel turned her attention to her, and she really wished that Mabel would stop mentioning the fact that they were paid for this. Did Mabel feel like a whore? Did Dipper? Had they actually done this before, for money? “So, whatcha know about positions? Any you like? You've at least watched porn, right?”
“Yeh-Yeah! I've seen porn. I'm not a baby you know!” Her face heated up, both from admitting she had watched porn, and the situation she was in. “I-I don't really know... though. It all looks pretty much the same.”
“No, no, no.” Mabel shook her head. “See if I'm on top, it rubs my clit more. Or on my back, it's more tender, and rubs my clitty too. If I'm on all fours, Dipper can go deeper, reverse cowgirl too!” Mabel continued listing off different positions, that she hadn't even been aware of, even started describing them, when she obviously didn't know what one was... It was so very confusing.
“Uh... which do you prefer?” Pacifica asked. Since she knew next to nothing about sex, and the Pines Twins were willing to educate her, she figured, they should at least be comfortable, and do what they like.
“Easy Peasy! I like being on all fours... and uh... reverse cowgirl.” Pacifica assumed it was due to those two being the two that allowed deeper penetration. But...
Her gaze fell on Dipper's member again, fully erect again. She imagined that deeper with Dipper, would be more painful. Did peppy, happy, excitable Mabel... like pain? “Um... all fours?”
“You heard the boss,” Mabel snickered smacking Dipper's bottom as she passed him, getting on the bed. 'All fours' was just as she imagined. Mabel on her hands and knees, her butt slightly raised in the air. As Dipper get behind Mabel, he motioned for Pacifica to come closer, which she did, after a moment of hesitation.
“So?” She just looked up at him, as he said the word. She was confused for a moment. “You're view? You think you'll see it all from there?”
“Oh... OH!” She actually paid attention to where she had been looking before. Mabel's backside, and just beneath it, slippery glistening pink folds, that were slightly opened, due to how her legs were spread. And a teeny tiny hole in the middle. She couldn't quite see the other girls clitoris, but she knew it was just out of eye sight. Then her eyes fell on the opposite of the tiny hole. The 'pole' that was Dipper's penis, which now looked a lot bigger up close. Still she couldn't figure out how, something that big was going to fit into something that small. But it seemed, that she was about to see it happen. “Yeah... I, uh, I can see.”
“Jeez, hurry it up already, Dipper!” Mabel's bottom shook back and forth, until Dipper's hands grabbed either side of it, to hold it still.
“Be still, or we'll repeat what happened the last time you were impatient,” Dipper's hand gingerly massaged the other girl's mons.
“Pfft, like that's much of a threat. Considering that lead to a whole other level to sexy time!” Mabel snickered... And Pacifica still couldn't imagine something that big going in her butt. Then Mabel shivered as Dipper rubbed the tip of his member between the girl's labia, and against her entrance.
Dipper pressed forward, as Mabel pushed back, until the tip of Dipper's member disappeared into Mabel. Dipper's hand moved from his penis, to either side of Mabel's bottom, then he slowly pushed forward, as Mabel moaned out a gusty sigh, Dipper letting out a throaty moan. Obviously he liked the feeling of his sister's insides.
As each inch vanished, Pacifica kept waiting for it to stop. Inch by inch Dipper disappeared into Mabel, until his thighs met the backs of hers. It was all in her! Every bit of it! Holy Cow! She missed it's exit to the tip, but focused again as it slipped back inside, a bit quicker. And she watched, as it entered and exited over and over again. The sound of flesh smacking against flesh. Squeaks and moans from Mabel, and grunts and groans from Dipper. It was like neither twin even remembered they had a viewer.
Pacifica didn't even know when her hand had ventured between her own legs, to massage her dripping, soaked, opening. An opening that would be fully open today. That tiny layer of flesh that had been with her all her fifteen years, would soon be gone, and replaced by a much larger piece of flesh. Dipper's flesh.
“Ungh! Come on Dip!” Mabel whined, as she gripped the sheets. “Harder! Fuck me! Pump your dick in my pussy!”
That was a shock. Who knew Mabel would be foul mouthed. She couldn't recall the brunette ever saying one curse word. But it was really doing it for her. Listening to those dirty words, coming out of Mabel's mouth, of all people, really lit a fire in her groin. Would she be a dirty talker? Would she shout obscenities was Dipper was... doing her?
She doubted it.
She couldn't even use the 'F' word in her own mind, so how could she yell them out?
Wait, did she just hear the word 'cum'?
“God yes! Pour that dick juice into my tiny pussy. Fill me up!” Mabel screamed, as Dipper picked up the pace... a pace that looked like it would really hurt. But Mabel just started thrusting her body back against her brother. And there was no doubt in Pacifica's mind, that the people in the rooms near theirs, knew what was going on. Because Mabel was pretty vocal. Then Dipper's hips stopped after slamming into Mabel once more, again his hips only twitched, as Mabel moaned out, “Yes yes! Fuck yes! Oh fucking GOD!” Mabel's body shivered and convulsed a few moments, before her front half laid against the bed, and only her bottom remained in the air.
Yeah, if there was any part of her that believed this might still be a joke, the semen leaking out of Mabel's slit, around Dipper's penis, blew those thoughts away. No one was that committed to a joke.
Both of them panted for a while, neither moving except when they needed to breath. Finally, Dipper pulled back, and Mabel shivered a bit. Before letting her whole body fall on the bed, Dipper doing the same right next to her.
“One of the best sexy fun times,” Mabel murmured into her brother's ear, as she curled up next to him.
“Yeah, but you can't go to sleep like normal.” Dipper said poking her nose.
“Why not?” Dipper looked over at her, and Mabel's eyes followed. “Oh Liver! I almost forgot!”
Guess foul mouthed Mabel was gone, and non-cursing Mabel was back. Liver seemed to be one of the most used 'curse words' that Mabel used. Maybe it was due to her intense dislike of liver.
“Sorry Paz, Mabel turns into a space cadet afterward.” Dipper smiled sheepishly, and she wanted to ask when Mabel wasn't, but she didn't want to insult the sister, of the male, that was about to be taking her virginity soon.
“Come on, come on.” Mabel said getting up. “I want to sleep, and I can't until you two do the horizontal mambo. So let's go, so I can go to sleep.”
“Mabs... you know... I kinda have to wait to go again. Remember?” Dipper just looked up at Pacifica, with an embarrassed look on his face. Of all the things the boy should have been embarrassed about, and he chooses the most normal one out of the situation, and blushes about that.
“Crackers! Wait... alright... alright. How about this? It's late. Paz paid for the room, for tonight. So... what if we pay for the room tomorrow, and then we can sleep now. I get to sleep, Dipper gets to recharge. And Paz, gets to sleep with us, and be all cuddly.”
Cuddly... Pacifica Northwest was many, many things. But Cuddly? Yeah... that just wasn't one of them. But... it would be nice, to be able to absorb the information, and sights before she took her turn.
“It's up to Pacifica.” Dipper looked over to her.
“Uh... I, I don't really see a problem with it. I mean, it should be fine.”
“Come on Paz” Mabel grabbed her arm, pulling her down, between the twins. Mabel on her left, and Dipper on her right. Even though she didn't have her blanket, nor was she wearing any clothing, with both twins on either side of her, she had no fear that she would get cold in the middle of the night. None at all.
