AUTHOR’S NOTES: Sorry for the long wait, you know, life and all, but I promise that this story will continue till it reaches its conclusion, no matter how long that takes! Moving on, I would like to thank Christopher, xXDasXGoochXx, harem lover 26, PseudoFace34, Latham02, Saint_Wanker_Kris, and RandomReviewer for their reviews and comments!
Christopher: Over the coming chapters I will work on revealing the weirdness that’s been going on and why it’s making everyone so horny. That especially includes what happened to Wendy.
xXDasXGoochXx: The overall impression I get from the chapter 3 reviews seems to be that of bewilderment. Trust me when I say that I am going to make sure it all makes sense by the end, or at least try my best to lol. I’m glad you’re enjoying the story enough to read through it multiple times, it’s nice to hear that from readers and I hope the content warrants such dedication. As for your invitation, we already spoke privately about that. I hope the podcast is working out for your group!
harem lover 26: I have a soft spot for Wendy too. She’s also criminally underutilized on the show, even though she proved to be so badass in Into the Bunker. Still, sometimes you can’t help but hurt the ones you love, yikes.
There are plenty of secrets to discover, and not all of them belong to Gravity Falls.
PseudoFace34: Good to hear that you’re liking the story, sorry to hear that you’re kinda disgusted by it. The rape and violence tags are attached to the story description, so that is something that can be expected throughout the story. That said, I do like reading any and all criticisms. Don’t worry, I have some pretty thick skin.
Latham02: Hmm, I wonder how should I take it? Anyway, this chapter will begin to clear up some stuff, and introduce some fun elements. As for the weird dreams, well, I make no promises. ; )
Saint_Wanker_Kris: There was a level of ambiguity to the events of chapter 3, so it is something that I want to leave hanging in the air, but not for too long.
I did sorta neglect the Twincest last chapter didn’t I? Poor Mabel and Dipper!
RandomReviewer: And here’s the update! I hope you like. : D
So, once more, thank you everyone for your comments and reviews. As always, please rate and review, and in general I hope you enjoy!
Chapter 4
Menage a Pines
To Mabel it was like an eternity in Heaven. In reality the kiss had lasted about a minute, and her Grunkle Stan’s attic didn’t quite live up to Heaven’s reputation, and it wasn't like Dipper's bed was like a fluffy cloud or anything. But, it was good enough.
“Wow,” she said, quivering underneath her brother. He laid on top of her as their naked bodies touched and caressed, and as his masculinity ached to fill her girlhood. “Our first kiss ever. My brother is my brother and my prince, all at once.”
Dipper awkwardly smiled. “Yeah, I guess that’s true… but it wasn’t exactly our first kiss. I mean, you kinda kissed me first, remember? Like, 5 minutes ago, it was all crazy and I was all like ‘wow, my twin sister’s trying to stick her tongue in my mouth, this is insane Mabel, you’re insane, stop touching my penis!’ You know, good times.”
Mabel laughed. “Hah yeah, those were good times. I should’ve taken pictures, it would’ve been really nice to have some in my scrapbook. I seriously regret not taking pictures.”
The boy stroked the girl's hair, cherishing its texture as the strands slipped through his fingers. He doubted a more beautiful creature could ever possibly exist. “It’s still sort of insane. Like all sort of very Oedipal, only with my sister.”
Mabel ran her hand through Dipper’s scruffy hair. Her eyes narrowed seductively as she gazed up at her brother. “I disagree Big Dip, you wanna see something that’s really crazy?” Winking at him, she slowly led Dipper’s right hand down her body, from her flat bosom down to her stomach. Dipper’s cock twitched, Mabel could feel it. It elicited a giggle from her. Still lower she moved his hand. Poor Dipper’s mouth opened wide, transfixed by his sister and the anticipation of touching something he’d never touched before. She tilted her head slightly and licked her lips. He bit his lower lip when she finally led his fingers to her wet, tight sex. She motioned his index and pointer finger up and down her slit while letting out a little purr. “I bet you don’t feel eight tentacles or anything bro, just one wet pussy… cat, all for my BIG, bad boy.”
“P-Pussycat?” he said, gulping.
“Mmhmm…”
“Pussycat, wow. But, hold on, I mean, wow, uhm, Oedipal, um, Oedipus wasn’t an octopus, he was a king, who ended up having sex with his mom, it en-”
“Oh come on who said anything about sex with mom? I don’t remember that conversation. Do you want to have sex with mom? GASP, are you having sex with me just to get a taste of mom?”
Dipper felt the heat radiate from his face. “This just got real awkward. I-”
A single finger was pressed against his lips. “Dipperrr…” she said, wearing an impish smile.
He nodded. The boy was trembling ever so slightly as he readied himself, his heart pounding in his chest as he slowly descended his head for a kiss. And then I'll… be with her.
“Wait!” said Mable, just as their lips were about to lock again. He almost didn’t heed her request.
The boy stared at her, perplexed. “Wait… ?”
“It’s too dark.”
His balls actually ached. “Mabel, you’re killing me here.”
“I know… I’m sorry bro-bro…”
“No, it’s fine, Ok solution time, let’s see, I’ll just go turn on the lamp.”
“No dice. I shot it with my grappling hook. Again. Maybe I should stop doing that.”
Crrraaaapppp. “Ok, I’ll just turn on the regular lights.”
“No, too much light, it’ll kill the mood.”
“Then, cellphone flashlight!”
“No, that's even worse! It's so focused on one spot, I don't like it. And it kinda hurts my eyes a little.”
The boy was out of ideas, and it wasn't like his sex-obsessed brain would let him think of any more. “Then what do we do?”
“I brought my night light from home, it's in the suitcase in the closet. I wanna see you, for our first time... please Dipper?”
He wrestled with the urge to just penetrate her then and there, but, even with his cock erect and throbbing between his legs, Dipper nevertheless dutifully jumped out of bed. In his hurry he tripped and fell face first on the floor with a loud thump. His dick was the second part of him to hit the floor.
“Owwww,” he groaned.
“Sweety?” asked Mabel. “You didn't hurt your penis did you?”

“No”, he said, even though it stung so bad he was seeing stars. Still, getting up, he charged for the closet and rummaged in a mad haste for Mabel's suitcase. Finding it, he unlocked the clamps and tossed the clothing articles out of the way.
Mabel touched herself while looking at her brother's naked little butt bent down and unintentionally mooning her. Just minutes ago he had been fighting to keep her away, but now... You're practically killing yourself just to get into me. It made her heart flutter. Oh Dipper.
“Found it!” he yelled, and with the little bunny rabbit night light in hand he raced toward the nearest electrical socket. Its dim light subtly filled the room with a muted orange aura.
“Aww, and here I was enjoying the full moon.”
“There's no- ohh,” he said, blushing. “I didn't realize. You liked that, huh?”
Ever smiling, she laid her head and hands down on her pillows. She looked away, her stomach suddenly full of butterflies.
He got back into bed, and on all fours he crept his way to his awaiting sister. She turned her head back to meet his gaze, swooning as he pressed his loins against hers, and as he leaned down for a kiss.
Their tongue’s twirled in their mouths roughly. She whimpered, and he whimpered back. Dipper suddenly realized he wasn't sure what he was actually supposed to be doing. His fingers tinkered with the string protruding from her loins. He didn’t think about it though; his mind was too preoccupied with Mabel’s swirling tongue for him to really notice it. He wanted to penetrate her, that much was for sure, and his fingers had just barely gotten to explore her velvety little entrance. It was only when he tried inserting a finger that he noticed the little cylindrical thing inside her pulsing vagina. Their lips disentangled, much to Mabel’s protest.
“No, don’t stop,” she whined, panting, placing a forearm on her forehead. “I’m putty in your arms. Your skinny, girly little arms.”
Dipper rolled his eyes. “You got your tampon down there.”
Mabel covered her face. “Oh my gosh, this is 50 shades of embarrassing. Wendy let me have this and I just, completely forgot! The good news is it’s not bolted in there or anything. You can just give it a little tug, I’m not bleeding... as much. I hope, or else this is going to get pretty messy.”
Looking away from Mabel, and somewhat embarrassed himself, he pulled the somewhat reddened thing out. He wasn’t about to get back out of bed, so it was with some luck that he managed to successfully toss it into the waste bin across the room.
“Score!” cried Mabel.
He looked at her vagina, at its smooth flesh and thin slit. He wasn't sure if he was expecting it to start gushing blood or something. “Is it weird to be doing… this, while you’re on your… you know.”
Maybe shrugged. “I don’t think I’m self-conscious enough yet to find that weird, but what I am is a horny little slut who likes to get fucked really hard in my tight little pussy till it bleeds.”
The boy’s jaw dropped. “Wow, Mabel. Wow.”
Mabel giggled. “What? We basically watch the same porn, so I know what those dirty girls say when they’r- aghh!” Interrupted by Dipper's tongue being thrust back into her mouth, she squealed, then wrapped her hands around his neck and pulled him tighter against her body. The heat of his frame warmed her all the way to her core. Those soft, girly hands of his groped at her rear. She giggled into his mouth, enjoying the feeling of his length prodding at her cunt. The butterflies in her stomach fluttered wildly while images of flowers in bloom, petals being plucked, and of white, feathery wings spreading opened filled her mind. She spread her legs for him, longing for his prodding boyhood to find her virginal entrance. She gulped his saliva down, and panted out for air each time their kisses briefly ended.
After some time she stopped lip-locking and spoke again. “Take me,” she begged lustfully, “ravage your innocent little sister, turn me into your woman, make me your Bella Swan!” He nodded rapidly and kissed her again. His cock continued to prod and poke her labia, sometimes rubbing against her clit, a couple times missing her loins all together and grinding at her thighs. They still kissed, though their raw thirst for each other seemed to thaw. Mabel lay there, brushing his hair, her eyes shut as they stopped making out and his attention became keenly focused on her loins.
It was after a good few minutes of her occasionally kissing him and him ineffectually poking at her pussy that she reopened her eyes. “Dippy. My big Dippy?”
“Yeah?” he said, still trying to do anything he could to get things started.
“Do you need help?”
Dipper’s face turned beet red. “Uhm, it’s not as easy as it seems.”
“It's ok, let me help you.” Mabel took Dipper’s dick by her hand. She stroked it gently, his groans so very arousing to her. When he got about as long and hard as his dick was going to get, she slowly guided him to her slit. “There you go, do you feel me?”
Dipper moaned softly; she felt him buck at her entrance. They both were eager to consummate their relationship, though in his urgency he had once more failed to enter her, his cock instead slipping along her wet lips.
She stroked the boy’s ear, giggling, and despite his frustration he couldn't help but giggle too. “Calm down, lover,” she said. Taking hold of his length again, she once again positioned it on her opening. “There. Dipper?”
“Lover?” he asked, staring wide eyed at Mabel. Never in his whole life did he ever imagine Mabel, his twin sister, ever calling him that. Their love for each other was undeniable, that much Dipper always believed. It was ingrained in them as brother and sister, flesh and blood, a bond both held dearly within their hearts that proved unbreakable even in their worst bouts of sibling rivalry. But, lovers? Is that what we are now?
“I just said something stupid didn’t I? Ack I told himself I wasn't gonna get all weird and clingy again, I don’t-”
“Sshh,” he whispered, placing a finger on her lips, “my lover.”
She cooed, giving him another kiss as she held onto him. With eyes closed and her heart racing, she parted the kiss and gazed into his eyes. “Please be gentle.” It’s absolutely perfect.
Mabel yelped as she felt his head split her lips apart. He was inside her, his hot, meaty length quickly filling her up and stretching her virgin canal open. She wondered if that was what gentle was supposed to feel like, or if he was just so completely enamored with lust that he couldn’t control himself. His first thrust truly had hurt like Hell. It was surprising because he wasn’t really that big, at least as far as she could tell. Then again it wasn’t like she ever had something even his size in her before. He was gleefully pumping away inside her, and he didn’t even ask whether she was ok. Was he supposed to? She wrapped her other arm around his back and held him closely. She clamped her teeth together and grimaced at the sharp, stinging aches that were brought on by each of Dipper’s quick thrusts.
She was warm, so incredibly warm. Her skin, her breath, her welcoming, moist insides, every part of her was pure heat radiating like a flame in the dark. He planted another kiss on her lips. She uttered a strained moan and invited his tongue back into her mouth.
What am I doing? he wondered. Another thrust quickly pumped into the girl writhing underneath him, another twirl of his tongue around hers while with one hand he stroked her hair and the other he held her hand, another and another, until it was like their bodies were one. Their kiss parted, he looked down at the girl he was making love to, at his lover. He didn’t understand any of it; was it a fever dream, some sort of nightmare, or something else entirely?
Am I hurting you? His sister laid bare for him, with her eyes shut tight and eyebrows arched. Her partly agape mouth dimly glimmered by the glow of a child’s night light reflecting off her braces. He heard her breaths, little sharp pants that she released with each pump of his body at hers. Dipper had never seen her sister’s face like that before, contorted into an expression somewhere between pain and pleasure. Her fingers interlaced with his.
He was hurting her, he was sure of it. He remembered hearing that it was supposed to hurt for girls, but that they would like it more in time. Was he supposed to have even more sex with his sister in the near future? He grunted out loud at the thought of it. He was making love to her now, grinding into her without pause, watching her pained expression that seemed to both beg for an end to her ordeal and yet seemed lost in the pleasure of their union. The thought of actually stopping never crossed his mind.
He was genuinely surprised by how little control he had over himself. Every thrust seemed automatic, like somehow his body just knew to do it, like a reflex hidden deep in his genetic makeup, waiting for the very moment that it would be needed. And it just felt so good.
But he still had no real idea what he was doing. He wasn't sure if he was pleasuring himself correctly, and as for thrusting, was he even doing it right? Was he hitting the right spots? And what of Mabel, did she enjoy it as much as he did? He tried to figure that out just by her expression, but all he could think about was how beautiful she had become to him, and how much he needed her more than ever in their 12 years of existence.
After a while he realized he was having trouble climaxing. Just how long was he supposed to last? It felt good to have her tight, warm canal pleasure his penetrating member, but even so he realized just how awkward it was, going in and out of what was basically a hole. A very nice, fleshy hole no doubt, but still a hole, one that just happened to belong to a girl, never mind that the girl just happened to be his sister. Maybe I really am doing this wrong. He tried pumping harder and at a higher angle. Am I missing something here? He leaned in and kissed Mabel's neck with soft little pecks that made her moan loudly.
Her gentle hand ran down his shoulder to his rear, giving his bottom a squeeze. Her body began bucking along with his. “Cum,” she purred out, her voice quivering with both longing and pain, “lover, please cum.”
He tried pumping faster. “I wanna cum.”
“Cum baby cum in me, cum inside me,” she begged. “My lover, my prince, my Dipper, cum in me.”
She was in pain, and the poor thing couldn’t take it anymore. “I’m your lover, and you’re mine,” he desperately grunted, “tell me you want it.”
“Yes, yessss, cum in me.”
“Yes, you’re mine, all mine, keep saying it, keep saying you want my cum!”
She wrapped her legs around his waist and squeezed him tighter to her groin, their breaths quick and hot on each other’s faces. Their lips smacked together between bouts of groaning and whispered pleading. “Cum in me baby, cum in me, cum in me, cum in me, cum Dipper, please cum!”
Her canal tightened around him, clenching all along his length. He didn’t know she could do that, or how much better it felt to buck into her womanhood when it was like that. You’re mine, mine, he said to himself, pumping harder and faster than before. Was he hurting her more by doing this? He wasn’t sure, but those pleas were intoxicating, and to hear his name whispered through her pursed lips, the same ones he had licked and kissed and nibbled on, drove him to bang her as hard as his small body would allow. You’re mine, and I wanna fuck you till you break!
The friction of her small canal against his enveloped cock finally pushed him to his long sought climax. “I’m cumming!” he yelled. He kissed her lips and cheek and tongue while he unleashed his seed in his sister.
“Yes baby cum,” she cooed, her voice breathy and exhausted, her face and body mildly shimmery with sweat, “cum in me, cum in me, please cum in your Mabel.”
It was as if her canal was squeezing at his length to drain him of the semen that he so exuberantly released in her. In a short moment it was over. The pleasure came and went, quickly to be replaced by the pain of her clenching sex clamping down on his sensitive member. Dipper winced as he pulled his spent self out of her. He gave her one last kiss on the lips, and exhausted, then laid himself to her left side, with an arm around her shoulders from behind and another on her stomach. He entwined his legs with hers. For a while they stayed unmoving, only panting in the otherwise silent room.
Dipper gazed intently at one side of Mabel’s face as she looked up at the ceiling. The boy, his respirations slowing, wondered what she was thinking about. Had she liked it? Was she feeling any pain? Had he been any good at all?
Mabel turned her gaze toward an anxious Dipper. For a while longer they just stared at each other in silence.
Then she burst out laughing.
“Mabel?” asked Dipper.
The girl covered her mouth as she continued giggling uncontrollably.
“What? What is it? What’s so funny?”
The girl shook her head. “I love you.”
“What?”
“I love you.”
His heart pounded in his chest. He kept gazing at her giggling sister, unsure of what to say. Or maybe he did. “I… I love you too.”
The girl clasped her hands around her chest. Their faces were a barely a couple inches apart. “No, but I mean, love love, not just love.”
He smiled. “No, I mean it, I love you, I really do.”
“I know, I love you too. But not like, not brother and sister love. I mean, I love you that way, but I love you love you. I love you. Dipper, I don’t know how I’m supposed to say it, I don’t know. You don't like vampire and werewolf novels, so, I can't use that stuff, you just get all agh when I do. Urgggh, why is this so hard? I just, ju-just, I don’t know! I love you love you…. love you! Why isn’t it coming out right?!” Her drunk-like smile went from its giddy visage into one of frustration and tears. She choked on her own words, unable to force them out as she sat up in bed and began softly sobbing.
Dipper sat up, and facing her, frantically caressed her shoulders. “Mabel, what's wrong? No, don’t cry, please don't.” The boy’s heart crumbled in his chest. What just happened? What could he have said to cause her to break down so completely? The boy brushed the sobbing girl’s hair, kissed at her reddened, tear streaked face.
“I-I… Dipper!” the girl blurted out. She thrust her head at his chest and held onto him so tightly that it hurt.
Quietly he looked down at his weeping sister. The sad girl’s tears were cool on his chest.
The boy clung to her, rocking her gently. It was overwhelming: the tears, the sex, the love and warmth of her body on him, the need to ease her suffering. How inappropriately horny he still was. The boy, shaking and overcome, began to weep too.
Mabel heard his sobs, and left the comfort of his chest to face him. “Dipper, why are you crying?” she managed to get out.
“I-I-”
“Dipper?”
“Don’t cry, please don’t cry, I’m so sorry! I didn’t mean to make you cry! I love you, in every way possible, forever and ever!”
Mabel wiped the tears away from her brother's face. “Forever?”
“And ever,” he replied, wiping the tears from her cheeks.
For a moment the both of them only gazed at each other. Then Mabel burst into tears once more, much to Dipper's bewilderment. Fresh tears rolled down the boy’s cheeks.
“Don't cry you doofus!” she scolded him through her sobs, “I’m just so happy, so happy to be with you! So stop crying before you make me really cry.”
“I was worried, so worried that I hurt you, or that you didn’t like making love, or I was too rough, or, or…” The tears ran anew down his face.
“No, it was perfect. You're perfect. So stop crying!”
“I’m trying!”
“You’re not doing a good job!” Mabel, forcing a giggle through her sniffling, made herself stop tearing up, if only for his sake. She stared at him lovingly, admiring the man he had become. Suddenly she lunged at him, their lips connecting as he fell backwards onto the bed; the two tasted their salty tears on each other's lips. Stunned by the shift from tears to kisses, he grabbed hold of her and held on for dear life. The girl was a ferocious kisser, licking and flinging her tongue at his with full abandon. He allowed her do as she wanted, letting her hands run up and down his body, letting her cup his ass and thrust her wet loins at his hardening cock. When their lip lock ended, she pressed her lips to his ear while dry humping his thigh.
“I'm so horny,” she whispered in a low growl.
The boy took her by her wrists, arose from his state of lying, and pinned her down to the bed. He was ready and absolutely willing to take her again. Mabel, rubbing her legs together, teasingly spread her legs open. Looking down, he noticed the mess of fluids leaking from between her legs. Light blotches of red blood stains tracked along her thighs and entrance along with his cum and the juices that had flowed from her pussy. His stomach's first reaction was not positive, but still, he suppressed the urge the retch. It’s just blood, he reassured himself, it's not like it's even the first time I've seen her bleed, from down there even. How much did I cum did I get in her?
Mabel, curious as to what about her pussy Dipper found so riveting, decided to take a look down there for herself. “Wow,” she gasped. She touched her slick slit, letting her fingers get coated in that combination of cum, lube, and traces of her own blood. The sheets under her were stained with those fluids. The girl moaned. “We’re gonna new bedsheets.”
“I don't really mind,” he said, still intently staring at the girl's loins, “it's just us making love.”
The girl clung to the pillows around her as the boy lowered his head. Her legs were quivering. “Are you really going to do what I think you’re going to do?”
“I love you,” he said, smiling warmly at her.
The girl sighed in pure bliss. Those three little words turned her body to puddy. He was already kissing her thighs. Her fingers dug into the pillows. She was on the verge of tearing up again. No, don’t do that, it just freaks him out. You softie! My softie. “I love you too. But you don't have to, you don't, I just want to make you happy.”
The boy started by sucking on her clit. She dropped her head onto the pillow with a sharp moan and shut her eyes. She heard and felt him slurp and lap up the creampie between her legs, eagerly drinking up what had been inside her just moments before. Our cum is in his mouth, that’s so incredibly hot!! “Oh Dipper yes! Eat me all up!”
Clutching her thighs, Dipper had that strange combination of bitter, sweet, and metal that was the result of their lovemaking on his tongue. He kept lapping up the juices, and noticed Mabel’s attempts to push more of it into his mouth.
Mabel couldn’t help but peek at her brother sucking on her sex. She petted the boy's hair with one hand while with the other she pulled at her pert, aroused nipples. Their lovemaking had stung her, much more than she was willing to admit to him, and though she had adored his every thrust, and there had been some pleasure gotten from his rocking, by the end she had just wanted him to simply finish. But this was incredible. The things he was doing with his mouth, with his lips tight around her clit, rhythmically suckling while his tongue flicked at it, made her body grind into his face. The girl was lost in the throes of her ecstasy; her body was tensed and shuddering. Yelling, she shut her eyes and came, her mind blanking out on everything except for the sensation of her brother’s still suckling mouth.
After a few more laps Dipper stopped pleasuring Mabel, and with her climax ebbing, he parted their passionate oral sex.
Mabel wanted to taste herself. She got up and went in for the kiss. Their mouths made contact, and as they moaned, he filled her mouth with their cum. She groaned in sheer delight. She loved it, absolutely loved the taste of her brother’s spunk. That they were sharing it, the product of their love, as they made out, felt so deliciously perfect.
The girl swallowed every drop that Dipper let leak into her throat. “Wow, so that's what we taste like? It's so creamy, my tummy loves it! I want more.”
“Do you now?” asked Dipper, as he tried to spread her legs again, only she resisted him.
“No!” she mischievously teased. He tried manipulating her with a series of kisses along her neck, soft pecks that elicited hushed whimpers from her. It was like she was melting away, yielding to him and the wonderful things he could do to her.
Only she didn’t. “No!” she shook her head, letting her hair wildly whip across his face. It drove him mad.
“I don’t get it,” he said, as he tried to force her down. She giggled and play-fought back. Whatever she was getting at completely puzzled and yet fueled his arousal. They rolled around in the bed, the one twin trying to get a better hold of the other. A pillow went flying into the air and hit a stack of Dipper’s books; somehow Mabel’s grappling hook fired and broke an old vase. Mabel eventually won by tackling Dipper and tickling his sides, and staying on top of him while the boy kept laughing.
“The Alpha Twin dominates still!” she proclaimed, panting. The girl kissed his chest, her lips pressing gently on his small, boyish nips. Dipper stroked her shoulders and back, and then he gasped when one of her palms touched his member. It had shrunk from all the tickling, though it grew when she motioned her hand up and down his length. She gazed into his eyes as his pelvis pumped up at her clenched fingers. “I wanna suck your dick.”
Dipper was speechless.
“Well?”
The boy nodded.
“Are you going to stop me this time?”
The boy shook his head from side to side.
“We'll see.” The girl turned her gaze from his eyes to his chest. She could make out a couple chest hairs, little short thin strands protruding out and curled. She found them adorable, just like the first one she had plucked from his chest and saved in her book. She kissed both hairs. “I finally have you where I want you.”
Kissing down his abdomen, she brushed her cheek and hair just by his sex, something that made the boy’s legs twitch. She started by kisses his scrotum; she tasted the bitterness of his drying cum on his wrinkly, hairless flesh. His semen was an acquired taste, she was coming to understand, though it was one she was definitely willing to keep devouring until she thoroughly acquired that taste. While her hand kept running up and down his pulsing manhood, fresh pre-cum streamed down from his dick’s tip, making her jerking motions all the more smooth. She smelled his pre-cum, and with her nose practically poking at his testicles, she sniffed deeply at the manly odors originating from his nether regions.
Mabel fingered her dripping cunt, penetrating herself as she also poked and rubbed her clit. Though Dipper’s enthusiastic but not at all skillful lovemaking had left her sore, it still felt good to play with herself. And she still yearned to please him, to pleasure the man she had given up her virginity to, to give him her pussy whenever he wanted it, and to make him the happiest man on Earth. You’re my man. My kinda skinny, not really developed man. I’m sure you'll fill out though, especially with a little incentive from your dearest sister’s cunt. And even if you don't, I don't care. Because I love you.
The idea of more sex both excited and made her nervous. Even pumping two fingers into her tunnel of love caused her some discomfort, but to let his dick back in so that he could take her again like before? She wasn't sure she wouldn't just outright faint.
Well, I still have a mouth after all. I hope that’s enough to use you all up, cause if not, I’m gonna be in biigggg trouble. Mabel giggled while suckling on Dipper's right testicle. She gazed at him as innocently as she could with her eyes wide open, searching for any sign that might indicate that she was being a good lover to him. He petted her head and watched her without pause while making the cutest little facial expressions.
The girl kissed both his balls, gave them a heavily saliva-coated lap of her tongue, and then licked the underside of his dick. His body jolted; he couldn't take his eyes off her as she slithered her tongue up to his pre-cum oozing head. Giving his head one quick, teasing poke, she puckered her lips and slipped his penis into her mouth.
No, he wouldn’t stop her this time.
Mabel groaned and licked at the tip of his yummy urethra while drinking up the clear fluid that came from it. Her hand hadn't stopped stroking his dick; it jerked whatever flesh wasn’t surrounded by her tight, clenching lips. The girl’s gag reflex was the only thing preventing her from just swallowing his entire cock. After orally cherishing his member for a while, she decided a little bit of nibbling might really drive him nuts, and grinning, bit ever so lightly on his cock.
“No teeth, please hon,” he rebuked, tugging on her hair just slightly.
The girl was stung by his words, though she did find the hair tug oddly exciting. No teeth, I just hurt my lover. Slowly nodding, and with a kiss given to the area she had bitten, she continued her oral embrace of her brother, sans the nibbling. I hope I didn't ruin this for him.
“I love you,” he said, with a strained voice. She looked so precious to him, so ravishing.
“Iw wuff uou tuu,” she said, with about half his cock in her mouth.
Dipper gripped her long, messy hair and tried to ease her lower down his manly pole. For her part she tried to comply, even though she really couldn’t handle much more than a few inches. It really was too much: she choked on his length, and barely kept herself from coughing. The gagging and retching sounds she made caused her to giggle out of sheer embarrassment.
Dipper giggled too. The sound of his sister choking on his length was so sexy to him. Even so, he didn't want to risk making her to puke all over his junk, especially on their first night together, and eased up on her.
Eventually Mabel parted from his dick. A long clear string of pre-cum and saliva connected her lips to his cock. “I’m sorry Big D, but my jaw hurts. How about if I masturbate you off? Is that ok?”
Big D? That's going to take some getting used to.
He was a little disappointed that she wasn't blowing him anymore. Still, he wasn’t going to say no to a hand job. She wasn’t particularly good at oral sex, he concluded, though it wasn't like he had any real frame of reference. But she was eager to learn, and he was eager to let her practice. What deeply turned him on was how candid she was: 'I wanna suck your dick,' 'how about if I masturbate you off?' You’ve always been the kinda girl that just went for it.
Mabel continued kissing and licking his head, lapping at it like a lollipop. The rest of his manhood she fondled by hand.
His neck sore from watching his sister, Dipper gathered up a couple pillows and dropped his head on the pile. Sighing, he closed his eyes and focused on her oral and manual stimulation. He wanted to cum for her, just to appease her. Throughout this whole thing she seemed so vulnerable to him, so unsure and lost. Eager to please, but not really sure how. He could relate.
When he opened his eyes, the first person he saw was not his sister.
At the foot of the bed, behind Mabel, the other person stood, silently, without a word or movement while Mabel obliviously kept working Dipper’s shaft. Mabel’s eyes were closed while she savored him, otherwise she would’ve seen Dipper’s wild terror. The boy was petrified, his whole body tense at what he thought he saw, and then because of what he did see. He was about to scream out the girl’s name at the foot of the bed, to scream out Wendy’s name.
Wendy pressed a finger to her lips, and then pantomimed zippering them shut. Dipper, his heart racing, stopped himself from yelling like a madman. He wondered how she had gotten in their room without them noticing. The attic staircase always creaked like something out of a horror movie, and so did the floor. How hadn't they heard her just saunter in? Why hadn't they locked the door? He could've sworn he had, right before bedtime. But there she was, just watching. Why was she just watching? Was she shocked by the sight of twins having sex?
How am I going to explain this away? he wondered. ‘It's not what it looks like, I swear!’ is NOT gonna cut it. He needed to think something up, and quick, but as it turned out, getting jerked off wasn't conducive to quick thinking. Wait a minute, why are you almost naked?
The teen girl was dressed in nothing more than her button up, which wasn’t even buttoned up. He saw the curvature of her cleavage along the opening of her shirt, and her pale, freckled flesh lit by the night light. He couldn’t stop looking at the red, trimmed, feminine bush between her legs, or the fingers she was using to rub her clit with. She leered at him suggestively, pleasuring herself while he watched and while an oblivious Mabel strove to make him burst his load.
His sister worked his shaft faster, clenching her grip tighter around his dick. It felt undeniably good. Maybe it was a hallucination, he reasoned. Wendy isn’t there, Mabel’s just fucking my brains out! That’s a thing right? I'm sure I heard that somewhere. Wendy pulled back her shirt, revealing one of her breasts. Thin blue bite marks covered her chest, something he couldn’t begin to account for. She cupped her tit and squeezed her flesh. She winced, as if the wounds hurt her, but she mouthed out a silent groan and seductively gyrated her hips for him. Mabel gave his testicles a series of slow, loving lashes with her tongue. He caught a glimpse of Mabel's eyes as she brushed back her hair and gave him a clear view of her smile.
He was so close to orgasm, and he had to admit, watching Wendy molest and finger fuck herself was definitely helping. He couldn’t hold it back. “Oh! I’m cumming!”
The girl, rather than continue jerking him off, took his dick back into her mouth and swiped her tongue along his veiny rod while he erupted. He dropped his head back on the pillow and rode out the climax. Helplessly he spurt his cum down his sister's throat while completely unsure of what Wendy might do next. After a couple more gushes the girl’s mouth was filled with his semen. Though his eyes were shut, he heard the audible gulp of her swallowing down his cum.
“Kinda bitter,” she remarked, smiling at him lovingly, even though he was looking away. “I mean, I liked it, but maybe you could eat more fruits and vegetables? I heard that can make it taste sweet. I really, really liked it though. Did you like it?”
“Mabel, Dipper! What the Hell is going on here!?” cried out Wendy.
Oh OK, nowww she’s yelling at us! Dipper said to himself in a panic.
Mabel turned around shocked and tried to cover her chest and young womanhood from the older girl. “It’s not what it looks like, I swear!” Mabel cried.
Wendy, with her pussy and a single tit exposed, stomped her foot at the floor. “Oh, then explain what it looks like, cause to me, it looks like you gave your brother… oral sex! And then you drank his… I dunno, guy milk!”
“No, it’s not true, I didn’t give him oral sex, I gave him a blow job, that’s completely different!”
Dipper smacked his forehead.
“Also I didn’t drink his guy milk… I drank his sperm. Oh, does guy milk means sperm? Cause I never heard of that before, but now that I think about it is kinda sticky and- wait, I wasn’t supposed to say that. Darn it, Dipper help me, I’m incriminating the both of us!” The girl jabbed her head into her brother’s chest and clung to him.
“I sa- I mean- wha, uh,” he stammered out, “But you! Wendy?!!! And then-?!”
“I’m on my period!” Mabel blurted out.
“Please don’t tell Grunkle Stan,” Dipper managed to say coherently, “he’ll tell our parents and then, I can’t even imagine what they might do. Please, we’ll do anything, just don’t tell him.”
Wendy’s eyelid twitched. “Tell Grunkle Stan? You gotta know me better than that. I would never snitch on you guys.”
“Thank you Wendy,” said Mabel. If her parents ever found out, would she even be allowed in the same room as Dipper ever again? She didn't want to find out.
“Nuh uh, you’re not off the hook yet little girl.” Wendy pointed to Dipper, “Or you, for that matter, taking advantage of your sister like that.”
“Taking advantage of? No, I’d neve-”
“Hush!” the teenager ordered, as she circled around Mabel’s bed. To the surprise of both of them Wendy started pushing the bed toward Dipper’s.
Mabel took notice of the older girl’s mostly undressed state. “Dipper,” she whispered, “something’s wrong with this picture. I mean, more than usual.”
Wendy was deathly pale, with bandages applied to her temple that were obscured by her hair. But there was something else off, beyond the tangible. Mabel didn’t know how to describe it.
The teen’s shirt kept slipping off, exposing most of her breasts. The twins could see the bite marks very clearly. They exchanged nervous glances. It didn’t take long for Wendy to arrange the beds together, and with a couple pants she sat herself between the twins. “So, Mabel, you completely ignored my advice. I told you to wait at least a couple years, and instead you go ahead and bang the first boy you see. Literally the first one, of all the boys in the world.”
“Are you all right?” asked Mabel.
Wendy shook her head. “No, we’re not talking about me, we’re talking about you two, and what you two just did to each other. You know, the thing with the incest, sweety.”
The teen placed her hand on Dipper’s thigh. “Dipper, what were you thinking? What am I saying? You're at that age where your penis does a lot of the thinking now. Expect that to be a life-long condition Dip. Just, your own sister?”
“But, I-”
She squeezed his thigh, placed a hand on his cheek. The boy trembled at her touch. “Hey, it's ok, I kinda get it, she's a very pretty girl. But you just don't do that to your sister. I have to nip this in the bud, right now... and I think I know just the way...” she puckered her lips and edged closer.
“Whoa I can't do that!” Dipper said, turning away from Wendy's kiss. His mind reeled from it: he had just declined a kiss from Wendy Corduroy.
“No!” said a shocked Mabel.
Wendy’s eyes suddenly grew colder, harsher. “Hey, I'm just saying, I'd hate for your Grunkle Stan to find out about what's been going on up here when he's not looking. After all, you did say you'd do anything to keep it a secret.”
“Are you trying to blackmail us?” asked Dipper.
Wendy held the back of the boy's head and pressed her breasts against his chest. He offered little resistance. “I have a feeling I won't have to.”
The young boy blushed as those lips moved closer once more. He had declined her once, but his desire for her grew more powerful, more overwhelming. He hadn't noticed how erect his penis had become just from her caressing his thigh. His one-time summer crush locked lips with him, much to Mabel’s dismay.
Mabel clawed at her own chest as the whole world seemed to fall away into nothingness. She fought back the need to weep, and also to gauge out Wendy’s eyes.
Dipper judged Wendy to be a much better kisser than Mabel was, but then again he reasoned she'd have to be, after all her dating history was no secret, not even to him. The teen reached around and held onto his bottom. A pang of guilt echoed in his mind, but only for a second.
Before Mabel could start crying Wendy pulled away from Dipper and thrust her tongue into Mabel’s mouth. The brunette whined loudly. She hated it. She hated how good it felt, she hated how much she liked it, she especially hated that Wendy played a better game of tonsil hockey than Dipper could. She hated letting Wendy rub at her clit. And I hate you for kissing my brother too. But she didn't hate it enough to stop her.
She was still horny. So incredibly horny, and Wendy was astonishingly adept at manipulating her private parts. Dipper joined in with kisses to Mabel's neck and shoulder while his hand tenderly gripped one of hers. He kissed every finger lovingly. It made her nipples and vagina tingle. She imagined that it was him touching her loins instead of Wendy, and longed to have his fingers inside her, playing with her till she reached climax.
Wendy and Mabel's lips parted; she was quickly re-introduced to her brother's familiar kissing embrace. While they made out passionately, Dipper and Mabel felt both their asses being groped by Wendy. Then she cut back in, getting another delicious kiss from Mabel’s lover, something that made Mabel burn with a jealousy so intense it was unlike anything she'd ever experienced before. What's wrong with me? she wondered, while she watched her brother sucking face with the redhead.
Wendy petted the back of the twins' heads and gently directed their mouths at her breasts. Despite Mabel's newfound hatred for her, both she and her brother submitted to the older girl. The twins eagerly began suckling on her nipples while a moaning Wendy shuddered ecstatically. She slid her button up down her shoulders and off her body, leaving her completely in the nude.
“Oh Dipper, Mabel, you guys are wonderful,” she said with a gasp. She hugged them both while they suckled hungrily at her teats. With Wendy’s tits firmly pressed upon their faces, the twins briefly exchanged glances, their eyes expressing shame, love, confusion, and plenty of other emotions neither could begin to name. A sliver of drool trickled down Dipper's chin. He groaned when the teenager took hold of his genitals and squeezed them ever so lightly. Both girls relished those little desperate sighs. Increasingly aroused and feeling more than feisty, Mabel bit down on the older girl’s hardened, perked nip. Squealing but not pushing her away, she nudged the little girl's face tighter against her wounded bust. She kept nibbling on Wendy's tit as her brother and Wendy touched and groped her body.
From the corner of her eye she noticed the bandages wrapped around the redhead's left forearm and wrist. A purplish-blue bruise remained uncovered lower down her arm. She gave Wendy's nipple one last suckle before looking up at the older girl. Her pointed, wet nipple poked at Mabel's cheek.
“Where did these marks come from?” asked Mabel, moving away from Wendy's tit. “Last time I saw them they weren't all… bite marky. It's like you ran boobs first into a wood chipper.”
Wendy looked down at her chest. “They don’t look that bad. It's just a couple bruises, no biggie. It happens sometimes, you know?”
“… what happens? Cannibalism? Dipper, back me up on- Dipper? Dipper!”
The boy wasn't paying attention at all. He was still sucking and lapping at Wendy's nipple with his hard-on at full mast. He didn’t stop till he realized both girls were staring at him. “Wha?” he finally said.
Mabel sighed. “You really are just thinking with your penis now, aren’t you?” She blushed despite how annoyed she was. She reached out and took hold of her brother’s penis and gave it a light pat. “Aww, I can’t stay mad at you. Look at that boner, it just wants attention. Ha, I said boner.”
“He’s got two gorgeous girls all over him, of course he’s stiff as a board and completely attached to my tits. The kid may be a little more mature than normal, but he’s still only a guy.”
Dipper scoffed. “Oh come on, it’s not like sex made me deaf, blind and stupid. I liked the part about me being mature though, maybe we can follow up on that.”
Wendy stuffed the boy’s face between her breasts. He happily accepted his place between her lovely twin peaks. “There you go sweety, maturely suck on those for a while. Now, as for you Mabel, I’m sensing that you're a little upset. Maybe we can work it out.”
Mabel huffed and crossed her arms. “There's nothing to work out.”
Wendy stared the girl down.
“I said no.”
The teen kissed the girl’s cheeks. Mabel wasn’t sure why she let her do so, but she enjoyed it nonetheless. “Hey, I get it,” Wendy said, “you love him, and you lost your virginity to him, the only boy you've ever truly loved, who’s also literally the only person you've ever known since before you were even born. Mabel, I’m not going to take him away from you. You and Dipper, I promise I’ll keep you together forever and ever. And as for me…” Wendy leaned in closer to Mabel's ear and whispered, “something tells me you’re not ready for another round of wild incest lovemaking with your very, very horny brother. Am I right?”
Mabel reluctantly nodded.
“Losing your virginity is painful for a girl, so how about I take care of him until you're less sore? Don’t worry, I’ll take care of you too. I love you like a sister after all. Both you and your brother, and me, we’re like one big, happy family.”
The redhead laid down and spread herself out over both beds. Mabel made out with the older girl, her kisses more unrestrained than before and guided by desires that could not be tamed. At some point Dipper had left the comfort of Wendy’s bosom and was now merely watching. “Come on Dipper,” his sister said, “what are you waiting for? Claim the gal pal you’ve been wanting all summer.”
It was what Dipper was hoping she’d say. He started with a kiss to Wendy’s crotch and her lower lips. It was weird having a fairly thick tuft of coarse pubic hair right in his face when Mabel didn't possess a single strand, yet he loved how different the pussy of one woman was from the pussy of another, and how much both equally enticed him. Licking at Wendy’s clit and then nibbling on it, Dipper found the older girl made a lot of the same kind of whining, mewling, moaning sounds that Mabel had. He looked up to see both making girls out, their lips smacking and smooching while Wendy fondled the younger girl’s clit. Mabel positioned herself on Wendy’s lap, and facing Dipper, opened her thighs up for his viewing pleasure. Dipper licked Wendy’s lube covered fingers as they flicked off Mabel’s little sex organ.
Mabel cried out loudly as she came. Her cum trickled down her pussy, with some of it dripping down Wendy's thighs too. Dipper lapped up the fluids while he began penetrating Wendy with his pointer and index fingers. The taste of copper and her sweet lube filled his mouth, and maybe there was a little bit of his bitter semen in there too.
Wendy swiftly and repeatedly tapped the cumming girl’s swollen pussy and clit; the sounds of her wet labia being smacked made Dipper’s hard-on ache for an entrance to enjoy. Wendy winked at Dipper, motioned her wet sex at him.
It was a difficult decision. Would he choose Wendy, or his sister, whom, despite her approval, was clearly weary of letting anyone else pleasure him? Did he really want Wendy that much? Did he have enough stamina left to take them both? Wendy curled her pointer finger, beckoning him to take her, to ravish and enjoy her the same way he had enjoyed Mabel, and the same way Wendy was enjoying her too.
Mabel squealed when her brother penetrated her again. He had gotten much better at it, taking merely a single quick thrust to fill her sore hole up to the base of his tool. You’ve always been a fast learner, she said to herself. Ow owowowowow.
“No, slow down, ow, oh wow owww!” she squealed as Dipper pumped away at her. Wendy held tightly to Mabel's body and arms, her breasts pressing against Mabel’s back as Mabel struggled in the teen’s forceful hold. “Please stop, please baby, please Dippy, please stop!”
The boy seemed lost in a trance, eagerly ravaging his sister regardless of the pain it caused her. Are you raping me, your own sister? “Take Wendy!” she yelled. Freeing one arm from Wendy's grip and grabbing the boy by his hair, she forced his eyes to meet hers. He finally stopped. She kissed the boys lips, whimpering as she tried to keep her tears in check. “You can have Wendy, I wanna share you, just calm down, please.”
Dipper pulled out. The girl sighed a breath of relief. “You’re such a rapist my little Big D.”
The boy gave her a confused look. “What do you mean? I was just… did things get out of hand? Did I really...?”
Mabel smiled. “Calm down silly, I'm pleasantly surprised by your devotion to me, and the way you took me so forcefully, which it turns out is a thing I like, go figure right? I wish I could let you too, but... not right now. Please don’t be mad.”
Wendy kissed the back of Mabel’s head. “I gotta say, you really lucked out on having the best sister in the world. Now I’m the jealous one, but, I think you can fix that.”
The boy went down on the Wendy’s pussy. The horny teen was thoroughly soaked enough to drench the sheets under her. He held onto her thigh with one hand and with the other rubbed at Mabel’s flat stomach.
“Oh… what a gentlemen,” Wendy cooed. She nibbled on Mabel’s neck while the younger girl watched her brother eat Wendy out. Mabel began to finger her own clit, “I bet he munched on your carpet too before he broke you in, didn’t he?”
Mabel didn’t answer back. It hadn't been lost on her that Wendy had acted as a sort of accomplice to Dipper's borderline rape antics. She didn't know what to think of it, even as she continued watching her brother munch on the girl’s carpet. And a carpet she did have, red and bushy, wild but trimmed. It was all so womanly and mature, definitely unlike herself. And of course she had womanly breasts to boot. A pang of jealousy shot through her heart to the very pit of her stomach. I could use boobs right about now. Big, huggable D cup boobs. Then he'd never look at another girl again. I'd hide kittens between them too. And candy. Mabel sighed. He likes mature girls more. The idea stung her bitterly, far more than anything Dipper could do to her. She suddenly felt very dirty and ugly and useless. I can’t even please my brother.
“Mabel, it’s ok,” Wendy whispered into her ear, “let me show you a good time.” Turning her head, and with Mabel allowing her to, their lips met once more.
Between aggressively finger fucking herself and having her tongue massaged into passivity, Mabel quickly forgot what had caused her so much agony and apprehension. Something about a kitten maybe. Mabel turned to face Wendy and planted her pussy on top of Dipper's forehead. He didn't object to having two pussies on his face, nor when a very naughty Mabel started slowly grinding on his cranium.
The panting girls kept kissing each other while they edged on the brink of another climax. “I wanna eat your pussy,” said Wendy in sultry, low voice, one that struggled to contain the ecstasy coursing within her. Mabel had never been told something so absolutely hot in her entire life. She responded by cumming while in Wendy’s arms, another orgasmic cry filling the room. The older girl, overdue for another orgasm and sufficiently stimulated by both twins, came as well.
Dipper felt both girls quiver and shudder: one while his mouth was firmly on her cunt, the other while on top of his head. The song of two girls climaxing in unison proved to be the most exquisite musical performance he had ever had the pleasure of listening to. Wendy gushed her juices all over Dipper’s face. He swallowed what he could, though he was completely unprepared for the sudden rush of female cum on his face. So this is how it feels to get a facial. Oh Jeez it's in my eyes.
Wendy plopped her head on a pile of pillows and spread her legs open for the boy’s throbbing cock. His manhood had already released a long clear line of pre-cum that left a long wet stain on the bed and sheets. “Good boy,” she panted. “Now, plow away Big D, you’ve earned it.”
Big D? Is that seriously what they're both gonna call me from now on?
Dipper turned to look at his dazed, giddy sister, who had settled herself by Wendy and was resting her head on Wendy's right tit. “Thrash her like a wrecking ball!” she exclaimed. “Come on bro-bro I know you got this!”
The boy had no trouble piercing the older girl and driving his full length into her. She automatically clenched her inviting, warm canal all around its stiffened guest. She bucked in timing with his thrusts, though a bit haphazardly; the girl didn’t seem quite as adapt at sex as Dipper had figured she would be. Still, he couldn’t deny how good it felt to make love- no, to fuck the girl he had been denied for so long. So much for ‘I’m too old for you’. Good riddance to that.
Mabel, content and feeling tingly all over, scooted up to the head of the bed and watched her brother fuck. She bit her lip partly because of her immense jealously towards Wendy, though really, perhaps it was more like envy. Dipper ravenously thrashed away at Wendy’s snatch while she loudly groaned like a bitch in heat. What I would give to have him do that to me. The redhead looked up at Mabel as she looked down at her. The older girl reached up and caressed the younger girl’s face. The urge to engage in more sexual escapades was quickly taking hold of Mabel again. She directed Wendy’s fingers across her cheek, and then slipped two of them into her mouth. She looked up at her brother while she mimicked fellatio on Wendy’s fingers. The boy noticeably increased his pace.
“So Dipper,” Mabel asked, as she kissed Wendy’s finger tips, “are you thinking about me while you're plowing Wendy?”
Dipper nodded exuberantly. “Yep, I always think about how wonderful you are!”
“Aww!” mewled Wendy, between grunts, “he’ s - ungh- a real sweetheart, agh-!”
“Are you going to take me like that every night?” she asked coyly while nibbling on Wendy’s digits. She was seriously considering letting Dipper have another go at her sore loins, pain be damned! How many times can you have sex before you give out?
“Every night,” he cried, “I’ll take you as much as you want!”
Mabel used Wendy’s hand to fan herself. He’s so romantic! “I’ll suck your cock every morning, I'll be your personal alarm clock, that sucks your cock!”
“Wow,” he grunted. The sweat covered boy leaned down and squeezed Wendy’s tits. Wendy visibly squirmed and uncomfortably so but didn’t prevent him from continuing to grope her wounded mounds. Regardless he tried to be more careful. I really should ask about how those bite marks got there. I definitely will, right after I cum. “You don’t have to.”
Mabel nibbled on every knuckle in Wendy’s hand. The redhead’s hand shook. “Come on Dipper, I set up a completely original, complex theatrical puppet play with 213 Musical numbers in less than a week just to impress a guy! A guy that probably only screws sock puppets anyway! I’m not joking about that either, some of his puppets were seriously questionable. And he had like a book puppet make out with a bee puppet, I mean, what was that about?”
“Yeah,” he said, while still grinding into Wendy, “you have the worst taste in men.”
“Not all the time,” she said, smiling.
Dipper blushed.
“Point is,” Mabel continued, “I think it's well established that I fall hard for anyone I'm in love with. So, obviously I have no choice but to make my master’s cock shoot off like fireworks on the 4th of July! Anytime time he wants it! We should make incredibly illegal recordings of each other and watch them to improve our sex life.”
“Master?” he barely managed to say between pants.
Mabel blushed and shrugged her shoulders. “I think it has a nice ring to it. Master. My Master, tell your slave what to do… she’s horny and wants to serve you.”
“Have her sit on my face, ‘Master’,” groaned out Wendy. Her free hand busily groped the smaller girl’s rear. She pinched her, making the little girl squeal. “Do you like that, owning 2 slaves that want to service you like the two under-aged whores that we are?”
Dipper kissed Wendy, silencing her except for the soft murmurs that accompanied each advance into the girl’s canal.
When they parted, Dipper bore witness to Mabel’s wet snatch grinding against Wendy's head, messing up her already disheveled hair. She seemed to enjoy doing that a lot. “Please Master,” begged Mabel.
This was the type of treatment Dipper could get used to. “Go ahead, my… slave?”
The act of sitting on a person’s face was still a weird experience for Mabel. She carefully made sure not to strain Wendy's neck with her weight by using her shins and knees to support herself. Wendy held onto Mabel's thighs and dipped her tongue into Mabel’s womanhood, expertly kissing the lips of her sex with her puckered mouth. Wendy slurped at the girl’s labia as Mabel arched her body at her probing tongue.
Grunting, Dipper listened to both girls whimper and moan while he leered at her sister’s naked form. Her little nipples were hard and pointed, her mouth stretched into an “O”, and her eyes shut tight. She reached out for her brother with one hand. The boy, ever in need of his sister’s touch, edged forward and kissed the girl’s mouth.
I’m being showered with kisses, Mabel said to herself, Kisses on my lips, kisses all over my girl-junk, I’m can’t believe how good this feels! This room smells like catfish.
They held hands as they made out on top the older girl. For all the gyrations and orgasms and wetness and spontaneous threesomes, Mabel found kissing him to be the thing she loved the most. She lost herself to their union, her mind gone amidst the orgasm that consumed her.
Dipper came as well, groaning loudly into Mabel’s mouth. They shook as they held each other. “I love you,” he whispered, gasping.
Though he was filling up Wendy with his special dipping sauce and not her, Mabel still smiled. “I love you too. Forever and ever.”
“And ever.”
Dismounting from Wendy’s drenched face, Mabel collapsed on the bed in a daze. The boy pulled out of Wendy and dropped by his sister’s side. The twins’ quick glance at each other expressed just how glad they were that Wendy had the foresight to push the beds together.
“You’re really good at that,” cooed Mabel, addressing Wendy but snuggling up to Dipper. She hugged him and nuzzled her cheek along his shoulder. “Oral sex I mean. I never came like that before.”
Wendy, smiling, took out her electronic cigarette from her wrinkled up shirt's front pocket and puffed on it. “I’ve had some practice.”
“Let me guess,” said Dipper, “you and Tambry?”
Wendy zipped her lips up and threw away the key. “You’re not bad yourself kid, I’m surprised this is only your… second time?”
He stroked the back of his head sheepishly. “Well yeah... Did I make you cum?”
Wendy averted her eyes from his and blew the vapor in her mouth up into the air. “You were very passionate, just really going all out on me. I liked it. Hey, you two mind if I cut in? It’s not like I’m not partial to a little post-coital snuggling myself.”
The twins made space for her. Wendy placed herself between them, sliding an arm around each twin. They rested comfortably on either side of her; Dipper laid a hand on her breast. Wendy let him, in addition to allowing Mabel to twill her red hair.
“You might have liked it,” said Mabel, “but I loved it when he made love to me. So… which one of us did you like more?”
Dipper turned beat red. “Wow, I- uh…”
“You better say her dude,” Wendy cautioned, drawing the cig to her mouth for another drag, “don’t piss off the chick that gives you head on a regular basis.” Wendy chomped her teeth together twice. “Not going to end well.”
“Definitely you Mabel.”
The twin sister tilted her head. “Hmm… I don’t know if you’re being honest with me or if you're just telling me what I want to hear. You know what would convince me?”
“More sex?” asked Dipper.
“More sex.”
***
Unfortunately the boy never did get around to proving his honesty. Exhausted and sensitive from reaching climax so many times so quickly, he had quickly fallen asleep. This left Wendy and Mabel with time to kill, which they did by continuing to enjoy the company of one another.
The aftershock of yet another orgasm slowly easing, Mabel laid herself by Dipper, and flicking some frazzled strand of hair away from her face, she watched her brother slumber away.
“He looks like an Angel,” said Wendy, wiping off a trickle of her cum off Mabel’s lips. “A shame he missed us. Oh well, I'll go ahead and show him a 69 when he wakes up. I'm sure he'll enjoy it, you did after all.”
Mabel felt Wendy’s breasts against her back. “Have you ever been so in love that it hurts just to see him sleeping without you?” asked Mabel.
“Uhh… can’t say that I have. Well, maybe, for this one person. Is that what you’re feeling for him? That’s so cute.”
The pitter patter of raindrops began to sound against the rickety rooftop. “It sounds like it's gonna start raining again.”
“You know,” whispered Wendy, moving in closer to Mabel’s ear, “there's something just so romantic about sex on a rainy night. It really sets the mood well...” She gently nibbled on Mabel's earlobe; her hand delved down the little girl's body till it touched her privates. “Did I ever tell you about my first kiss? Just me and my best friend, all alone in her room, with the sound of thunder booming outside...”
“Um, not right now please,” said Mabel, “I'm kinda worn out too.”
Wendy persisted in touching the girl. A finger slipped into her pussy.
“Please no,” she whimpered, as she took hold of Wendy's bandaged forearm.
The teen hissed at the pain and jerked her arm away.
“I'm sorry!” said Mabel. She covered her head, half expecting to be slapped by the older girl. The rage in the teen's eyes was beyond compare.
Cradling the arm, Wendy quickly calmed herself. “No, it's ok, that just took me by surprise. I’m hungry.” Standing up, she gave the girl's butt a smack. “You want anything from the kitchen?”
“I could use some coffee.”
Wendy's eye twitched. “I’ll see what I can brew up.”
“Make sure it has lots of sugar! Or just bring the whole bag of sugar, there's no such thing as too much sugar.”
Wendy didn't bother to put anything on. Mabel watched as the girl, her nude body glistening with sweat, walked over to the door.
“You never did explain what happened to you,” blurted out Mabel, right as Wendy was about to leave. “I heard screaming, a couple hours ago.”
Shrugging, Wendy turned back at Mabel. “It’s the strangest thing. I was just taking a bath, and well, you know, enjoying myself…. and then… I must’ve slipped and fallen, really hurt myself, just knocked myself clean out. I woke up hurting all over. I guess I got carried away… but like I said, it happens. Anything else, girlfriend?”
The teen's eyes flickered strangely in the dim light. For a moment Mabel wasn't sure who or what was in front of her. “You… fell?”
“Yep. Fell and hurt myself, especially my arm. That’s probably what that scream was, before I passed out.”
“Wendy, is it really you?”
The older girl crossed her arms across her chest. “What’s that supposed to mean? Of course it’s me. What, I get a little slutty with a couple of close friends and suddenly I'm a different person? And then there's you going at it with me in the bathroom earlier. That’s a little hypocritical, you know.”
Mabel lowered her eyes. “I'm sorry.”
Wendy narrowed her eyes at the other girl. “Get our little boy toy up and ready, I’m itching for another round of crazy incest related sex, just you, me, and that geyser of a boy you call your brother. Aren’t you?”
The girl slowly nodded.
Before leaving Wendy eyed the coat rack and the shawl Mabel had hung on it. “By the way, this crazy thing, with all the feathers, I’m really starting to feel it. My shirt kinda got buried under our bodies while we were doing the nasty, so now it’s all sweaty and cum-stained and rank. Way too gross to put back on. You mind if I borrow this? I wouldn't want to give your Grunkle Stan the wrong idea, trouncing all buck naked in the kitchen.”
“Go ahead… Wendy.”
Donning it, Wendy almost tripped on something on the floor. Cursing under her breath, she picked it up and then shut the door behind her.
Mabel gazed down at her snoozing brother. You do look like an angel. An angel I’m going to molest in his sleep. She reached down and took his softened penis in her hand. Its tip was still moist. She hummed softly while she stroked his shaft. The repetition of that movement comforted her. “Dipper, bad things are going to happen, and you have to wake up now because I need you to help save the day.”
She sighed. “The truth is, I’m afraid. Not as much as I think I should be, but afraid enough to know that I can't handle this alone. But I guess that’s because I’ve never really been alone, cause I've always had you.”
She kissed him. His cock seemed to straighten as she barely pecked his lips. The boy murmured something but kept fast asleep, even as she licked the boy’s mouth ever so gently. He didn’t wake up, which was fine with Mabel; she liked watching him take his slow, deep breaths.
I need to wake you up, but I don’t want to. “I like that you’re a good listener.” She contemplated going back down on him. That would surely do the trick. Plus, her hand was starting to cramp a little.

It had been raining, and it was starting to rain again. His suit was soaked from head to toe in water. What was he doing outside, standing around like a dumbass having a stroke? Was he having a stroke? Stan was certainly at the right age to be stricken with one. He himself thought it was only through a sort of wild luck that he was even still alive, especially considering the dubious choices he had made throughout his life. Looking up, the sky was dark and ugly, with the rainfall slowly accelerating.
He wondered how long he had been out there, right outside his home, with his car keys in hand. The last thing he could recall was walking out of the house so he could buy tampons. Something told him he didn’t make it very far.
He looked at his watch. It was too late to go to the store anyway. Sighing, the old man walked back into his home, removing his soaked blazer as he stepped through the doorway and tossed it aside. He’d deal with the mess tomorrow; right now he was exhausted and somewhat perplexed, but if anything, he could at least tell himself it was the stress of what was soon to come that was causing him to suddenly black out. And it had been a stressful summer so far, even if it had also been a good summer. Just gotta keep it together for a little while longer. A few more days and… Stan looked at the mirror on the wall, at his own reflection. God I'm old. He placed a hand on the mirror. Just a few more days, you god damn moron. 30 longs years, and then it'll all be over.
Now topless except for his wife beater, Stan went off to the bathroom. A random noise coming from upstairs distracted him. He looked up at the darkened stairwell. It wouldn’t hurt to check on the kids first, he reasoned.
Up the stairs he went, slowly as to not disturb them. It wasn’t until he reached the attic door that he heard it, a strange sort of rhythmic noise, something familiar to his ears but that couldn't possibly be what he thought it was. He slowly opened the door, its creak seemingly unnoticed by Mabel, who, completely in the nude, and sharing a bed with his equally naked but sleeping brother, seemed to be playing with his genitals.
Someone was behind him; he heard the person's creaking steps ascend the staircase. Oddly and irrationally tense, he quickly turned and slammed the person hard against the stairway’s wall.
Wendy suppressed a squeal. A dish with a couple of sandwiches dropped from her hands and a can of soda rolled down the staircase. “Whoa, someone’s gone a little cray-cray,” she snarked, “what, did you think I was gonna ambush you with a can of Pit? Well, those pits can be pretty lethal…”
Not quite releasing her, but easing his hold on her shoulders, he inspected the mostly naked girl. “What are you… what are you doing in Mabel’s shawl? And nothing else…?”
She rubbed at his arms. “Hmm, what are you doing topless, right outside of Mabel and Dipper’s room, all soaking wet and, dare I say it, excited to see them… or is that for me?”
Stan looked down at his pants and the pointed object hidden within. Wait, when did that happen?
In his confusion the old man let go of Wendy. The teen took the opportunity to pull out her Taser and jab it at him. But Stan still had some speed left in his old muscles, and with a quick dodge, avoided the weapon’s electric sting. He knocked the weapon out of her hand and it flew down the stairwell till it landed with a shatter of black plastic and bits of metal.
“That belonged to a vampire-human that was also the son of a space Nazi. That was one of a kind, so thanks, asshole.”
“What were you doing with my niece and nephew?” he asked, yelling.
“Nothing you weren’t already planning to do. Nothing you didn’t already do to me.”
“What?”
The girl laughed. “You think you're going to get away with it again. Though, you always kinda do, don't you?”
Stan felt the goosebumps rise on his chilled skin. “This is about last year, isn't it?”
The girl rolled her eyes. “Last year? No, honey, I’m talking about what you did to us tonight.”
“Tonight?”
“Did it make you feel like a big man, the things you did? The things your cock clearly wants to do again?”
When did this whole household go insane? “What are you even talking about?”
“And then what, were you going to brutalize me again, tie me up, and make me watch while you rape Mabel and Dipper? That must be making your blood boil… to be so close to fucking them-”
Stan slapped her across the cheek, much to his own shock.
“Yeah, that’s right,” she growled, “you like it rough don’t you? You liked beating your victims into submission before you violate them. Strangling them till you throttle the life right out of them. Isn’t that right?”
“Wendy, I’m sorry, but I have no idea wha-”
A scream came from the Mabel and Dipper's room.
Wendy stepped in front of Stan, who was already reaching for the doorknob. Now where do you think you’re going? With the grappling hook by her left side she aimed it and fired. That it hit his stomach was a little disappointing: she had been aiming at his head. Still, Stan tumbled down the stairs and landed back first onto the bottom step.
For a long time Wendy stood there, waiting for him to get back up, or maybe for a puddle of blood to form around him. “Hey, did you die?” she asked, as she descended the stairs. She recoiled the rope and hook back into the gun barrel.
As she got closer she could see his chest rise and fall. When she reached him she gave the sole of his foot a light kick. He was unconscious, but still very much alive.
Kill him.
A tear fell down her face. “I you need to die now old man.”
Kill him.
Wendy aimed the gun at his head.
Kill him.
Her hands were shaking.
KILL HIM.
The doorbell rang.
Wendy dropped the gun in surprise. “No way. At this hour?”
The doorbell rang again.
She gave Stan a hard kick to the back of his head when she heard him groan, knocking him out cold. “You stay quiet, or I swear I will shoot you right in the face.”
The visitor was incredibly impatient: he or she was already pounding their fist at the door in the few minutes it took for Wendy to roll Stan’s body out of sight.
At the door was none other than Pacific Northwest, who managed to stop just short of pounding her fist at Wendy’s crotch once Wendy opened the door. “Oh! Wendy! Wait, what?”
“Pacifica? What are you doing here?”
Pacifica looked up wearily at Wendy. After a short, anxiety-riddled silence she bit at her lip and sighed.
“It wasn't a dream.”

Dipper looked up to see his sister looking down upon him. She smiled affectionately.
The boy saw the wings spread out from her back, white wings with beautiful white feathers. He tried to sit up in the bed and kiss the angel that seemed to beckon for him.
“Stay right here,” she said, gently laying a single hand on his chest.
He obediently complied.
“Remember what I told you?” she asked.
The girl with the white wings wasn't Mabel, he realized. She looked like Mabel, even sounded like Mabel, but it wasn't her.
“Who are you?” he asked.
Dipper felt the weight of another person on his lap. It was Pacifica, positioning herself right on top his penis and, while holding it on the slit of her vagina, allowed it to penetrate her. He groaned as she bobbed up and down his impaling length, as she panted seductively while her perfect blonde hair shimmered and bounced in the dark. He looked back towards the Mabel look-alike, only to find that she was no longer there.
Pacifica Northwest lowered herself till her face was almost close enough to kiss Dipper’s. “What would you say if I told you this wasn't the first time this has happened?” She covered her mouth as he came inside her.
“What?” he asked. Pacifica covered his eyes.
“What would you do if you knew?” she asked. When she uncovered his eyes, Waddles the pig was sitting on his lap. Where Pacifica had gone to Dipper didn't know.
The pig’s black eyes stared at him unblinkingly. “His name is Bob.”
“HOLY TALKING PIG!” Dipper yelled as he awoke with a start. He tried to figure out just how much had been a dream. Did I really have sex with my sister? Was that real? Something warm, wet and tight was on his crotch, moving along his cock. He moaned as he watched her, his sister, still nude and dutifully pleasuring him orally like she promised she would. He had never awoken to anything so beautiful in his entire life.
“Oh Mabel…”
“Mabel? Are you sure about that?” said another Mabel, the one that laid next to him. She licked his cheek. “Mmm, you taste so good!”
The boy was completely shocked. He turned from girl to girl, completely disbelieving at what was happening around him. He could hardly focus either, the Mabel on his junk kept slurping away at his admittedly still very much rock hard dick.
“I know what you’re thinking,” said the Mabel hugging him and kissing his cheek, “‘How did Mabel Pines get so good at working your pine tree? It’s like she’s sucking the bark right off your trunk.”
It was too much. First Mabel, then Wendy, now two Mabel’s, and not to mention all the orgasms and the weird dreams, the boy simply couldn't handle it. He fainted.
The two girls looked at each other. “I told you the blow job was too much.”
“No, I told you the blow job was too much.”
Both girls grinned. “We told each other!” they cried in unison with a loud screech.
“Oh Lebam, I missed you so much!” said Mabel as she stroked the boy’s hair.
“So did I!” said Lebam, as she wiped her saliva off her lips.
Smiling, both girls ecstatically jumped at each other and hugged, shrieking again in unison. “Oh my gosh!”
“I could do this forever!” they cried out happily.
Mabel and Lebam looked down at the unconscious Dipper. “We have to wake him up again.”
The girls looked at the boy’s wettened, semi-erect penis. “It’s so cute,” they both cooed. They exchanged glances and shrieked once more.
