Sleep hadn’t come easy that night for Mabel. Even with all the trouble she’d had with Dipper that day, it still seemed wrong to have to sleep in the attic alone. She missed his light snoring, and the comforting feeling of knowing he was there with her.
But the time alone had not been completely wasted. It gave Mabel an opportunity to see just how insane things had really gotten. I can’t believe that was really me, she thought, remembering the out-of-control girl that was determined to harm herself in whatever way she could, then knocked her brother unconscious. I wish I could make Dipper understand that his idea of being safe is the same as breaking up! But still, he’s right! We can’t keep going this way. Something has got to change.
What if I really do have to let go? she thought. Could I ever think that I could be able to move on without him? What if … what if breaking up really is the best thing for us? The questions and anxiety flowed through her, bringing her to anguished tears several times. She tossed and turned for hours before finally the sadness and frustration could keep her awake no longer, and she nodded off between two and three o’clock. Having been up over twenty hours at that point, she’d fallen soundly to sleep.
It was after ten when she awoke. After moaning and stretching, she sat up and allowed her feet to drop heavily over the side of the mattress. Must’ve been crying when I fell asleep, she sullenly mused to herself as she rubbed the crusties out of her eyes. When she was finally satisfied that she had picked out all the gross foreign invaders, she raised her eyelids.
Just a few feet away, Dipper sat on the edge of his own bed, silently staring at Mabel.
Startled, Mabel screamed, triggering a short, loud scream from Dipper as well. Dipper put a hand to his forehead while Mabel pressed her palms to her chest while they both panted from the inadvertent twin jump-scares.
“Sweet Sally, Dipper!” Mabel scolded irritably between gasps. “What are you doing, sitting there all quiet and creepy? … How long have you been there?”
Dipper fought to calm himself as well. “For a while … I’m sorry, didn’t mean to scare you …”
Mabel took a good look at Dipper. He looked haggard, with even darker circles than normal under his eyes. He hair was a mess, and he was definitely wearing the same clothes as the day before.
“You don’t look like you’ve slept,” she said skeptically. “Did you even go to bed?”
Dipper shrugged. “No,” he admitted. “I had … a lot to work out.”
“Yeah?” Mabel asked without much enthusiasm. “What about?”
“Us,” replied Dipper softly.
Mabel regarded him tiredly. “Dipper, I really don’t wanna deal with this, okay? Not now, not when we just keep saying the same things over and over again.”
“But I-” began Dipper.
“Just go to bed!” Mabel interrupted. “I might feel up to talking later, so you may as well get some sleep now.”
Dipper wanted to protest further, but Mabel shut him down and stalked away to the stairs, headed down towards the bathroom. She was tired, grumpy, in no mood to listen, and she wanted time to think. Her thoughts the previous night had been about the possibility of giving up on being able to stay together with Dipper romantically, and she wanted to be in a better frame of mind before being forced to face him once again.
Morning gave way to midday, then afternoon. What had been a brilliantly clear and cold sunny day became overcast, dampening the atmosphere of the Mystery Shack further. Just one week removed from the winter solstice, daylight had disappeared well before five o’clock. Stan was tossing together a thick turkey stew for dinner, made from the remaining leftovers of their Christmas meal. It seemed like another day was already drawing to a close.
And yet, Dipper did not lie down to rest. As the day progressed, he stayed out of Mabel’s way, but was conspicuously present at all times.
Mabel sprawled in Stan’s chair in front of the television, staring disinterestedly at the third rerun that day of a documentary on the community access television station. Interest in watching the biography of the life and times of Gravity Fall’s deceased mayor Eustace Befuttlefumpter had waned hours ago. Her eyes flicked over to the sofa where her brother sat with a science fiction magazine. He was ostensibly engrossed in his reading, but Mabel was aware he hadn’t turned the page once since he’d sat down over a half hour before.
She sighed in resignation. “OK, fine, Dipper,” she conceded reluctantly, pushing herself to her feet and heading for the attic. “I’ll listen to whatever you gotta say.” She heard him following as she ascended the stairs. Dipper had latched the door closed behind them before she finished sitting down on her bed.
“Mabel,” Dipper began without preamble, “you were right! I was wrong for cutting off everything between us. There is a place for us! Not just here and now, but back at home, too! We belong together, and I think we should be together!”
Dipper’s short speech sounded well practiced. Mabel suspected that he’d rehearsed it many times in his head. Her face was expressionless.
“Um …” Dipper continued, “... what I mean is … I see everything that you were talking about. About your needs, and stuff. And … and I need them too! I know that now.”
Mabel continued her inscrutable examination of Dipper.
Sweat burst on Dipper’s forehead. “What I’m trying to say is … is that after seeing things from your perspective … I want us to be .. you know … lovers! And everything that goes with it! I think the risks-” He cleared his throat. “I think we can risk it. I think that ... as long as we’re careful, we can … we can do this. We can do this, Mabel!” He searched Mabel’s face for agreement, or even acknowledgement.
After a long silence, Mabel finally responded. “Dipper … I don’t think you believe that,” she said softly.
Dipper drew a breath to reply, but didn’t get a chance to disagree. “I let you talk, Dipper!” she interjected. “Now please, let me!” She could tell it was difficult for him, but he remained wordless.
“I get it. Because of what happened yesterday, and last week,” Mabel said. “I know that … I’m … pretty messed up. I shouldn’t have threatened to …” she couldn’t look Dipper in the eye, “kill myself.” She wiped her face quickly. “None of that is your fault. It’s mine! I shouldn’t have done that. And I get it! I scared you. It was scary for me, too!”
Looking away, Mabel continued. “But … I think you said all that just now because you’re just tryin’ to make me feel better. That’s not a reason to completely go back on everything you think.”
“Mabel-”
“It doesn’t make sense, Dipper!” Mabel plowed on. “I might go nuts and say or do something new and weird and different. But you wouldn’t! After how you were talking yesterday, none of what you just said now sounded like anything you would think. Not unless … you’re just saying what you think I want you to say!”
“That’s not it!” pleaded Dipper. “Please, Mabel, let me explain-”
“Dipper I’m trying to figure out what you’ve been saying since that bus ride home and about all the stuff Grunkle Stan has been saying!” Mabel cried, the words spilling out. “Maybe we shouldn’t have let things get this far! Maybe we should try to move on! Mayb-”
“NO!!” exclaimed Dipper. There was sheer panic on his face, and he leaped forward, grasping Mabel tightly by the arms. “No, that’s not what I was saying!! Please, you’ve got to give me a few minutes!”
Mabel was dumbfounded by the role reversal. She was trying very hard to change the way she saw their relationship, to bring herself to look at everything like the way she thought Dipper had been trying to make it. And now he was the one insisting that they be closer together than they had been! What was going on?
“Just a few minutes? Okay?” Dipper begged desperately, his grip firm on her arms.
Eyeing her brother warily, Mabel consented. “Okay.”
Dipper loosened his hold and blew out a relieved sigh, then his expression set again. He turned and paced to the other side of the room while rubbing his hands together, then spun on his heel and came back. After repeating his steps a second time, he stopped beside his bed and sat, head bowed in an internalized debate.
Finally he looked up at Mabel. “I know that this is going to sound pretty strange, given everything I’ve said before,” he said. “But after I said goodnight last night, after what happened to me … it’s different! I’m different!”
Mabel tried to hide her natural impatience, but it was difficult. “What happened? What’s different?” she prodded.
“Everything!” Dipper replied immediately. “I’ve been wanting to tell you all day! That I’m not afraid anymore! I don’t have to be afraid anymore! Because I don’t have to make any promises alone anymore! I … I asked for help.”
Confusion was obvious in Mabel’s knitted eyebrows. “You stayed up and talked to Grunkle Stan all night?”
Dipper shook his head. “No, not Stan …” He ran a hand through his hair. “Mabel, I know neither of us have been nearly as religious as Mom and Dad, but over the last while … I've really started to see what it's all about. And what the Bible has to say. And … and last night …” he swallowed, and looked down slightly, “... I gave myself to Jesus. I asked for His help.”
Mabel’s mouth fell open slightly, her eyes incredulous. Dipper had been right: this did sound very strange to her! True, the twins had been attending church with their evangelical parents all their lives. But while Mabel had not completely decided what she did or did not accept from Sunday teachings, Dipper had never indicated any leanings at all towards a strong Christian belief. She never thought it seemed to fit with his logical mind and questioning personality. But now here he was, showing a side of himself she had never seen before.
“... Wow,” Mabel said softly. “I … I had no idea, Dipper.”
He shrugged, still not making eye contact. “I haven’t wanted to make a big deal of it. I’ve kinda been, you know … working it out on my own.” He leaned his head over towards the head of his bed. “You know that black book I pulled out from under the bed last night?” Dipper asked. At Mabel’s nod, he continued, “It’s my copy of the Bible that I’ve kept here at the Shack. I pull it out every so often. I’ve hidden it here since last summer. Since before … you know … the whole ‘Weirdmageddon’ thing happened.”
“That long?” Mabel gasped, astonished that Dipper had kept this a secret from her for well over a year.
Dipper nodded. “Yeah. Then after going to church with Mom and Dad last Sunday, it kind of got driven home.” His eyes met hers. “All this crazy stuff we’re dealing with! Us being together, my concussion and other injuries, the pills … I should never have thought that I could ever control all this myself. I was insane to think it was possible! I’ve been fighting my whole life to have control over my life. So last night … I let go. I prayed, and … I asked Him to take control. I prayed to God that He do to me what He wants ... and that I would obey.”
Mabel was as rigid as stone, amazed by what her brother was telling her, though still not comprehending that what she was hearing was true.
“And the most incredible thing happened!” Dipper continued. “I actually felt the weight of everything fall from my shoulders! All the stress, the uncertainty … it was just gone! And this … peaceful kind of feeling came over me.” An unconscious smile crossed his face. “It was comforting … kind of like a warm blanket, only way nicer, and-” He stopped short, then looked timidly at Mabel. “... you won’t laugh at this part?”
Feeling she was almost in a trance, Mabel merely shook her head.
Dipper’s gaze was unfocused as he recalled the experience. “I heard His voice, Mabel! I swear I could hear Him talking to me … telling me … that everything’s going to alright!” He refocused on Mabel, his face optimistic and hopeful.
Mabel couldn’t quite bring herself to believe what she thought he was saying. “Dipper, what do you think is going to be alright?”
“Us!” Dipper exclaimed. “More than just us, actually! I felt … I felt this love coming from Him, I felt Him ... letting me know it was okay for me to just accept it, to go with it!” He waved his hands excitedly. “The Bible says that we’re to love Him, to love ourselves, and love others. I heard Him, Mabel! He said He wants me allow myself to experience that love fully! In every way! That includes you and me!”
It may have been for reasons that Mabel could not have predicted, but Dipper was offering exactly what she dearly wanted: an opportunity for the two of them to continue, loving one another in a genuine romantic relationship. But she'd also allowed herself to think this had happened the previous morning, and that had ended up being a disaster. How could she be assured that it would be different this time?
I want so much for this to be real, she thought. But it would just be too much to be wrong again! I couldn’t stand it if I was wrong about this again so soon! This story he's saying … it's unbelievable! I've never heard Dipper say anything like this about religious stuff. I need to keep my “skepticles” on tight!
“Dip, this is … really weird!” she said. “I’m sure you think you heard something, but couldn’t this be … you know ... ‘cause you just got knocked out yesterday? Maybe you’re just hearing stuff … stuff that’s only in your head?”
“No way! I’ve had a head injury before, Mabel. I know what it’s like,” argued Dipper. “If what I heard was a hallucination, I’d have had other symptoms. No, I really heard Him!”
Mabel’s emotional defenses slipped a bit further. She continued to fight against it. “OK, what if it was someone else talking to you? Or some-thing else? We’ve seen a bunch of cray-cray stuff happen around here, you know? Maybe you’ve got some invisible wizard or something whispering in your ear?”
“C’mon, Mabel! You’ve seen it yourself that all the weird things about Gravity Falls disappeared after summer last year,” Dipper said. “We were here almost three months again this past summer, and nothing happened that was unusual. Great Uncle Ford was right: Weirdmageddon was the end of the weirdness to this area!
Mabel put her face in in her hands. He’s right! This town was totally normal all this summer! Why would there be any change now? Her palms slapped down onto her thighs as she drew at one last straw. “I don’t know the whole Bible. I mean, I don’t even remember all the books in the New Testament, let alone the Old,” she said, forcing herself to remain collected. “But I’m pretty sure that there must be some verse in there somewhere that says siblings shouldn’t be gettin’ to know each other in the … biblical sense! You know?” Her hands gripped together tightly in her lap. “Isn’t the Bible supposed to be God’s word, or something? How do you figure that works with what your voice told you?”
Dipper scratched the back of his neck. “Yeah … I realize that probably doesn’t fit ... And I guess I don’t have all the answers. But ... “ He leaned forward, hands balled into fists, struggling to verbalize his thoughts. “... Mabel, I swear that after what I felt, it doesn’t matter! I know what I experienced, and I know it’s true! It’s like …” Dipper’s eyes squeezed shut tightly for a long moment. When they reopened, he refocused on his sister. “It’s like I know that there’s someone above us, watching over us all the time. That He’s there keeping our love safe! I’m absolutely certain of it!”
Oh God, thought Mabel, could this really be happening? Could Dipper really have heard God’s word? Could Jesus’ message of peace and love really mean that my feelings for Dipper could be forgiven? Would He really protect us and allow us to be together? It seems so wrong to think about, but so RIGHT to feel it!
“I just ... Dipper ...“ she whimpered, looking away.
Dipper slid forward off the edge of his bed and knelt on the floor in front of Mabel, peering up at her. “Look, even if I’m wrong, even if I didn’t hear anything … you don’t even have to believe it! What matters is I’ve been the reason we’ve been apart, and I promise … I’m not going to be getting in our way any longer!”
He gently took her hands in his. Mabel’s resistance was close to gone. She could not avoid his intense gaze, and her vision blurred from new tears building up in her eyes.
“We were meant to be together, Mabel,” Dipper said, his voice cracking. “You’ve been trying to tell me for months, and I’ve been an idiot trying to resist it. I was scared, but I’m not scared anymore! We don’t have to be … ‘cause we’re the Mystery Twins, dammit!” He half chuckled, half sobbed. “As long as we work together, and we take care of each other, nothing can ever keep us apart! You believe that, right?”
Nothing could stem the torrent of tears streaming down Mabel’s face. She swept away all of her remaining doubt, nodding vigorously and bursting into a loud wail of happiness.
“I … love you … you big … corny … dork!” she stammered between cries.
Dipper smiled with giddy happiness. “I love you too, Mabel,” he murmured back. He leaned up and gently put his hand on the back of her head.
Mabel lunged and straightened up, grabbing hold of Dipper and pushing them back towards his bed. They landed on their sides still locked in a tight embrace, their mouths firmly against one another.
Stan shook his head ruefully.
He had just climbed the stairs, ready to let the kids know that supper was ready. He expected that a meal might be a welcome interruption for his niece and nephew from more arguments and hurt feelings. Sure enough, he had heard the sound of Mabel crying in the main attic room beyond the closed door.
His knuckles had been poised, about to knock, when he also heard an unexpected sound: two tearful, quiet proclamations of love. Followed immediately by the protest of mattress springs, and gasps and moans of passion from two young teenagers.
Guess they’ve made their choice, he thought, withdrawing his raised fist. It wasn’t the call he would have made for them. He knew that they’d chosen a path that, while perhaps rewarding now, was certain to be very difficult in times to come. He didn’t regret encouraging them to forego the danger of such a taboo attraction, to let it go and move on as simply brother and sister again. He was certain his advice was the better choice for them.
And yet, a small and sappy part of him was secretly happy for them, hoping against hope that they shared a love together that just might be enough to overcome any obstacle thrown their way.
Might as well leave them be, he thought as he quietly descended back down to the lower level. I’m betting they won’t be done for awhile.
Stan served himself a large bowl of stew and sat down in his comfortable chair in front of the old television. He would be more than satisfied spending the evening eating his supper, while watching his favorite shows on the “Black and White Period Piece Old Lady Boring Movie Channel.” Preferably with the volume turned up louder than usual.
“I’m sorry …” Dipper gasped, a shamed, wide-eyed expression on his quivering face. “... I’m sorry …”
Mabel caressed his cheek. “It’s okay,” she whispered, eyes twinkling with suppressed mirth.
Dipper’s eyes slammed shut. He made a strangled noise of tension, his forehead pressed against his sister’s. Laying on her side facing him, Mabel slid her hand from his face to behind his head. Her legs entwined with his, she tightened her hold with her entire body and pulled him firmly to herself as he groaned urgently, followed by deep panting. Her other hand was between them, lightly gripping Dipper’s twitching penis. Warm semen was leaping from the tip, pooling on their stomachs and chests between their naked bodies. His suppressed moans faded as the last drops puddled into their belly buttons.
After several long moments of trying to regain his breath and dignity, Dipper gingerly reached with his free hand for his discarded t-shirt hanging over the edge of the mattress behind Mabel’s head. His face twisted in embarrassment, he began the awkward task of pushing a corner of the cotton garment down between them and started mopping up. Wearing a broad, fond grin, Mabel decided to allow Dipper to handle cleanup duty, since she had one hand busy running fingers through his hair, and the other occupied with his gradually wilting erection.
Dipper sourly regarded Mabel’s satisfied smile. “It’s not funny,” he mumbled as he folded the sticky mess over inside the shirt and started wiping their skin again with a cleaner portion of fabric.
“I’m not laughing,” Mabel replied, her smile softening with sincerity. “I’m just really happy to see that big ol’ Big-O face of yours, again!”
Dipper’s gentle ministrations continued as she lightly pecked his nose with her lips, generating a bashful look from her brother. “Yeah, well I guess it’s safer out here than … you know ...” His eyes rolled downwards, “... in there!”
Mabel's demeanor became serious for an instant as she quickly thought of the current date, then she relaxed again. “It’s okay, don’t worry,” she declared dismissively.
Concern flashed through Dipper. “But … but you could-”
“Dipper … I’m due for my little ‘crimson tide’ to start heading out a few days from now.” She grinned at her bro’s mildly horrified face as he processed the menstrual metaphor. “I’m safe! I'm pretty sure we don't have to worry about it.”
Trusting his sister, Dipper nodded. He tossed the shirt on the floor, flopped his head back down onto the pillow and exhaled loudly. He looked downcast, his eyes showing both his fatigue and his disappointment in himself.
Mabel traced a finger through his hair. “Dip, it’s really okay,” she whispered with affection. “Hair-trigger or not, I love that I’m the one who can do that to you!”
Dipper shrugged. “I just wish that, you know … you couldn’t do that to me quite so quickly …”
“Well, you did last a lot longer than the last time we did this,” Mabel said quietly with pride, nuzzling her nose to Dipper’s.
“Maybe a little,” he agreed shyly.
Mabel gave a quick tug on Dipper’s softened member. “Not so little a minute ago,” she whispered saucily. Dipper’s grin finally appeared as their lips met.
The kiss began as gentle and playful, with soft pecks and blissful smiles. But slowly, the intensity of the moment increased as they continued to experience the joy of finally being together again, of no longer feeling any barrier between them. Soon the noise of the winter breeze’s light rattling of the window was drowned out by the sounds of skin caressing against skin, smacks of tongues and lips, quiet gasps, and stifled moans.
Still holding tight to one another, the kids allowed their mouths to part unhurriedly, and their gazes met again. Wordlessly they stared into one another’s eyes, a silence that was both perfectly comfortable and taut with intense emotion.
Mabel huffed with giddy frustration. “I don’t … I don’t know how to tell you how you make me feel!” she breathed, a teary look of desperate happiness on her face. “I just have these … dumb words, and there’s so much more I want to tell you about inside me, and … and …” She produced a muffled exclamation of ironic annoyance as she started lightly tapping her forehead onto his.
“It’s okay, Mabel. I know,” murmured a smiling Dipper, brushing a small drop from Mabel’s cheek. The smile grew as he gently pushed her over onto her back and snuggled up to her side, an arm holding her tight under her shoulders, and guiding his knee over her thigh. “I don’t have the right words either,” he continued, still lovingly watching his twin's gaze back at him. His free hand slid down from her face, caressing lightly over her breast and stomach. Mabel’s mouth opened and she gasped with increasing arousal as his hand continued towards its destination between her legs. “Let me show you exactly how I feel,” Dipper whispered.
Mabel whined and gently intercepted the hand, grasping Dipper’s wrist and firmly holding it over her abdomen. “Dipperrrrrrrr! You … you don’t have to!” she moaned. “You’re exhausted! We were just going to cuddle together until you fell asleep, remember?”
If he was honest, Dipper would have admitted that his body and brain were both very close to being completely spent. But there was no way he was going to allow himself to succumb to fatigue now. His eyes flashed, another adrenaline rush coursing through his body, giving him renewed energy. He quickly leaned over Mabel’s face and pressed his mouth enthusiastically onto her lips. Their tongues danced in a rhythm Mabel was unable to resist, drawing a louder moan from her. Their lips separated with a loud smack. “I’m not tired!” he promised, kissing her again. “And you deserve to feel good!”
The fingers of his trapped hand began a tantalizing tickle on Mabel’s skin below her navel, forcing her to squirm and giggle. “Quit it!” she squealed, then laughed louder as Dipper just grinned and sped up the movement of his fingers. She had to force Dipper’s hand away, and brought their arms up to lay on top of her chest. “I love you, you goober!” she cried, lowering her chin to kiss his hand. “And … well yeah, of course I want to feel good, but … isn’t there plenty of time for that later?”
“I don’t want you to wait anymore, Mabel,” pleaded Dipper. “It's been too long. And I … I need you! I really want to feel you right now!“ Dipper’s hand was being held to Mabel's chest, so he set his fingers to the task of lightly caressing her breast. “... I need you to know …” Mabel gasped as a finger found her nipple. “... that I …” Dipper hovered his lips over Mabel’s mouth, feeling her shuddering exhale as his finger and thumb gently squeezed. “... love you, too!” Mabel was beyond resisting, and her grip on his wrist involuntarily went limp.
His hand now free, Dipper smirked and again patiently traced his fingers south as he placed kisses on her face and neck. He felt soft pubic hair on Mabel’s mound and she grimaced at the touch, but he kissed her with a warm smile while experimentally moving his fingertips through her short curls in small, languid circles. Extending his reach further, he ran a featherlight massage over her outer privates. Mabel’s entire body was imperceptibly shaking in aroused excitement.
Dipper coaxed Mabel's legs to spread a bit more and began carefully pressing his middle finger between her labia, giving him access to her inner folds. His fingertip found the entrance to her vagina, and he slowly pushed it into the hot, moist tunnel. Mabel twitched and made a short, loud moan of pleasure. He manipulated his finger in and out of her, sensuously painting her fluids further up into her split with each stroke. Finally he drew his finger over her clitoris with agonizingly slow speed, adoring the look of ecstasy that came over Mabel’s face, her eyelids fluttering closed. Dipper placed his lips sweetly over her eyes before making a trail of kisses down to her neck. He was loving the feeling of Mabel’s uneven breaths and body shivers, caused by the attention he was giving her with his finger and mouth.
He craned his neck back up to Mabel’s ear. “I love you!” he whispered almost inaudibly. “This is how I want you to feel, and how I feel about you!” Then he slid his mouth down, over her collarbone and to the firm breast closest to him. His lips surrounded the nipple, gently squeezing it, followed by his mouth opening and playing his tongue and teeth delicately over the erect nub. At the same time, his hand slid lower, allowing his finger to carefully work its way back inside of her while his thumb gently rubbed Mabel’s sensitive button.
“Oh my gosh!” Mabel gasped as her legs spasmed. She was unable to control her reactions: Dipper’s loving assault was powerfully erotic. Mabel had been suffering months of withdrawal from any arousal, her depression and drugs working together to lower her sexual drive. She had not even felt the desire to masturbate since the middle of September, not even once. Now intense physical sensations ripped through her body, feelings magnified by her restored relationship with her brother. She whimpered aloud, holding on to Dipper’s head as he suckled passionately on her breast and caressed her most intimate parts.
Dipper was elated to feel how Mabel was responding to his ministrations. He couldn’t recall her reactions to his mouth and fingers ever being so fervent before. Without stopping, he glanced up to her face, and didn't think that she had ever been so beautiful! Sliding his body against hers felt amazing, and he rocked in rhythm with Mabel’s gyrations. He could tell that her breasts had definitely grown a bit since he had last seen and touched them, and they felt incredible against his cheek and lips. He lunged across her chest to nurse on her other nipple, pulling his arm free from behind her neck to continue with his free hand to fondle the one he'd abandoned.
A strangled noise escaped Mabel’s throat as she fought the urge to yell out with pleasure. She wasn't sure how much time was passing as she felt as if a coil within her was being compressed tighter and tighter. She needed the coil to let go, and she writhed harder and faster against Dipper’s mouth and hands, desperate for release. She obliquely wondered how her brother was able to do this to her, and how deliriously happy he made her.
Sensing Mabel was on the brink of orgasm, Dipper latched his mouth firmly to her breast and ground his teeth into her nipple with perfect pressure. Just as her torso tensed, he drew his finger out and up to her clitoris, rubbing her up and down as rapidly as he could.
That was more than enough stimulation for Mabel. Her every muscle went rigid, and she felt that her entire body might fly apart. She could have sworn stars began glowing behind her eyes. Then the stars burst and everything seemed to explode. And the fireworks wouldn’t stop, as Dipper continued to lovingly manipulate her over the edge again and again. She was barely aware of the strained noises of pure joy she was making while she drowned in a sea of overwhelming bliss.
“Stop!” Mabel finally managed to gasp, flailing and lightly hitting Dipper’s head and hand. He grinned broadly, tweaked her once more to tease one last ecstatic reaction out of her, then held her close as she helplessly splayed out flat on her back and gulped great lungfuls of air.
Dipper nuzzled his mouth close to her ear. “I love it when you do that!” he murmured.
“When I … do that?” Mabel panted incredulously. “That was all … you! I didn’t … do anything!” Mabel’s whole body felt numb and electric at the same time. Trying to give a better hug to this wonderful and considerate nerd, she raised her arm and let it flop clumsily, dropping her palm with a soft smack onto Dipper’s smiling cheek.
Her goofy style of showing affection made Dipper chuckle. Then he made an over-exaggerated show of being knocked unconscious again by the blow, crossing his eyes and letting his tongue hang out of his slackened mouth.
“Dipper ... you butt!” Mabel complained. “That … is not funny!” She thrust her bottom lip out, trying to put on a comical display of pouting even as she struggled to regain her breath.
Refocusing, Dipper got a look at Mabel's face and snorted again. “Yeah? Well then go easier on me, okay?” he laughed, and gave her a hard full-body squeeze. After reaching up for a tender kiss on her temple, he backed off only enough to be able to look deeply into her eyes.
She fixed her gaze back on him. The expression on the cute, dorky face inches in front of her was one of pure and limitless adoration, and something inside her melted even more. She knew Dipper loved and cared about her, and had always known this fact for as long as she could remember. But now, the face of this boy revealed so much more, betraying the truth of how close the twins had become. He’d said so before, but she now knew it: Dipper would do anything, anything at all in his power, for her. And only her!
It was impossible at that moment for Mabel to not fall in love with Dipper even more.
Mabel could not let this realization pass. Dipper had to know what this meant to her. He had to know how she felt about him. Immediately. And completely! Her muscles reacted instantly. She grabbed his head with both hands and thrust her mouth onto his.
Dipper squeaked in amusement, then made a wide-eyed exclamation of muffled surprise as Mabel quickly twisted and wrapped her arms and legs around him. In seconds she held him tightly and had pulled him on top of her, his pelvis between her legs and his rejuvenated shaft resting directly on top of her loins.
She broke the kiss. “I need you, Dipper! Now!” she gasped impatiently, pushing her hand between them and reaching for his penis while grunting under Dipper’s weight on her chest.
“Okay!” Dipper breathed, instantly invigorated by Mabel’s desire. It took him a second to get his elbows and knees under himself, and no sooner had he done so, he felt Mabel grasp his erection in one hand and a butt cheek in the other. She guided him straight to her entrance. Mabel's insistence was catching, and as he urgently snaked his arms beneath her lower back and neck, Dipper felt the tip of his length penetrating her tight channel. Then Mabel wrapped herself around him, crossing her ankles behind his thighs and her arms around his back.
For a split second time seemed to stop. Dipper supported his weight above Mabel as they panted shakily, their foreheads and noses pressed together.
Then with a soft cry, he sheathed himself to the hilt in one stroke. And as he wrapped his tongue around hers and squeezed her torso tightly to his own, his hips kept pushing, trying to crush their bodies together even more if at all possible.
Seconds before, Mabel was desperate for Dipper, needing to feel more of him. Now, she felt all of him! His arms held her, his penis was deep within her, his body and mouth covered her, and his love filled her. She rejoiced in their pure intimacy together. Dipper’s tiny, fast pelvic thrusts were grinding his pubic bone directly onto her defenseless clitoris nonstop. Another loud moan escaped Mabel’s throat, her facial expression distorted, and she quivered helplessly in Dipper’s embrace as a sustained, sweet climax washed over her.
As she slowly came down, Dipper loosened his hold on Mabel. He loved seeing the look of supreme contentment on her face.
Mabel felt Dipper inside her, and knew he was still very hard. Her eyelids fluttered open, and she looked back at him. She wondered if she could ever feel better than this, and she knew she was about to find out.
“Again, Sir Dippin’ Sauce!” she whispered dreamily.
Dipper smiled. “As you wish, Lady Mabelton!” he murmured back. Very deliberately, he drew back his hips, almost pulling his entire penis free. Then Mabel pulled in a long, delighted breath as he pushed back in equally slowly.
“Agaaaaaaaaain!” Mabel sighed, placing a palm on Dipper’s cheek. He snorted softly and gave her a tender kiss.
Then together, they made love.
They were unhurried, and had no fears or worries. Gone for the moment was anyone who could hurt them, or their relationship together. The twins revelled in the freedom they were finally allowed to experience. There was only each other. It was the most beautiful moment either of them could possibly imagine.
The pace of the twins’ lovemaking increased very slowly, the rhythms of their movements together inexorably synchronized. Despite their emotional distress of the past months, a lifetime of knowing each other almost as much as themselves prepared them for the perfect dance they shared now. Their young bodies heaved and writhed together as one, glorious physical sensations joining with their trust and faith in one another to drive them forward ever faster.
“Oh … Oh Dipper …” Mabel moaned.
There was no one else for Mabel, she knew without a doubt. She loved Dipper with everything that she was! She could imagine no way that the universe could ever allow for the creation of any emotion in her as strong as what she felt for him.
“I love you, Dipper! … I love you … so much!” she panted as she moved in time with Dipper’s thrusts.
“I love you … too, Mabel!” Dipper gasped back, holding himself up over her and looking deliriously happy.
They were perfect together, she knew. It made no difference to her that he was her brother! She only loved him more because of everything they had experienced together! They had always been there for each other, even in the womb. And they always would! Forever!
“And we’ll always be together …” Mabel cried happily, “... right?”
Dipper’s expression changed instantaneously. His smile disappeared. His eyes opened wide as saucers. Mabel’s words had seemed to shock him to the core.
“Oh God!” he panted, completely serious. “I want nothing more … Mabel, I ... I love you so much …” His movements resumed with even more ardor, as his instincts ordered his body to demonstrate the intensity of how he felt.
Mabel could see and feel the desperate power of Dipper’s emotions. Her body responded, clutching and moving with him.
“... I will do everything …” Dipper continued, wetness forming in his eyes. “... I’ll do anything …” He continued making love to Mabel even more fervently even as a tear dropped onto Mabel’s cheek
Not wanting to see Dipper in distress, Mabel reached up to lower him to her breast, and to get him to stop and calm down. But he shrugged off the attempt.
“No! Mabel, you deserve so much!” he said tightly. “I can’t bear the thought that … that we’d ever… that I’d ever do anything ...” Dipper tried and failed to suppress a sharp sob, and a stream of tears leaked from his eyes. Even so, his embrace tightened and his hips thrust even harder.
Then suddenly Dipper squeezed his eyes closed and he arched his back and neck. “Oh my God please!” he cried out. “Please, you can do this! … You can let Mabel and I be together!” Another wracking sob broke from his chest. “She deserves to be happy! Sh- … she deserves … everything!!” he managed to choke. Even as he took a huge unsteady breath, he still drove his body to keep up his attempts to prove his love for his sister.
Mabel’s heart lunged at Dipper’s plea. She could hardly believe how much emotion Dipper was capable of, that his love for her could be so strong! She had never seen him beg and plead so hard before. He was exposing his deepest vulnerability and newfound faith, all the while making her feel incredible physical and emotional pleasure. And all for her! A high-pitched, almost pitifully soft wail escaped her throat.
“I don’t deserve her!” Dipper sobbed, his eyes now wide open and staring at the dark sky through the window. “But … please … if you could just … have mercy on me!” His whole body moved in a frenzy now, attempting to fuse his body and soul with Mabel. “Please!!” he begged desperately.
Mabel was overcome by Dipper’s passion and despair. Blithely unaware of her own tears, she lunged up and clutched him tightly with her entire body. Every part of her squeezed him as hard as she could, including his penis deep inside her vagina, even as she knew she would fly apart at any moment.
“PLEASE!!” Dipper practically yelled. Then he let out a loud, anguished cry, his self-control gone as the massive buildup of sexual stress in his groin passed the point of no return. He collapsed into Mabel’s strong full-body embrace as an unimaginably intense orgasm completely overwhelmed him.
Nothing could stop Mabel from climaxing at this point. An almost hysterical scream of sympathy, love, and lust burst from her as she held her wonderful brother, catching his salty tears on her face while feeling him throb deep within her, his tears and semen becoming part of her. Nothing had ever felt so intimate, so powerful before in her entire life!
After eventually releasing her grip, Mabel let Dipper slide sideways beside her, and their muscles finally relaxed. They lay sprawled together in a sweaty, teary pile on Dipper’s bed for several minutes, sobbing and gasping heavily for air. Neither one could do anything but just stare in wonder at each other, near disbelief that they’d just shared such an unforgetable and beautiful experience together.
Mabel finally began feeling the chill of the cool attic air on her damp skin. Without releasing Dipper’s hand, she reached down to the floor for her discarded sweater and used it to wipe up the majority of the wet and sticky coating from both of their bodies. Dipper let her work without speaking, the rise and fall of his chest and his heavily lidded eyes the only parts of him that moved.
Satisfied that they were both acceptably dried off, Mabel sat herself on the mattress beside Dipper and pulled the sheet and heavy blanket up over them.
“It’s okay, Mabel,” Dipper muttered weakly. “I’m not tir-”
“Shush! You are, too!” Mabel interrupted. She quickly fluffed her pillow high on the bed and laid down, pulling Dipper close with his head tucked by her collarbone. “No more arguments, apologies, or hanky panky. You need to sleep!”
At first his exhausted face showed his defiance of her orders. But then he smiled reluctantly and snuggled into her body, hugging her beneath the covers. She felt the last of the tension in his muscles disappear.
“I love you, Mabel,” Dipper whispered into her chest.
“I know,” Mabel replied quietly, kissing the top of her brother’s head. “And I love you, too!” Dipper was already half gone, and fell sound asleep seconds later.
Mabel held him as he slept, secure in the knowledge that she was exactly where she wanted to be. Sure, she felt gross and sticky, and could use a shower to get cleaned up. And yeah, she was hungry and pretty darn thirsty, too. But all that paled compared to resting there with Dipper. All the heartache and depression was washed away, with only love in their place.
At last, after all this time, the Mystery Twins were complete again!
