Rushing into the lounge room of the Mystery Shack, leaping off the step and landing on the faded carpet, Mabel confronts her Grunkle Stan who was bending over, turning on the TV. He looks up from the screen, filling with static before cutting to Gravity Falls cable television, and smiles at his grand niece.
"Hey there kiddo, your brother coming down soon?" Stan asks, putting down a VHS video box on to the table to turn to her. From the look of his slanted eyebrows, Mabel could sense that shared her profound joy at spending summer together again.
"Yep, thanks for everything Grunkle Stan." Mabel says, running up to the man and embracing him, wrapping her arms around his torso in a large hug.
Stan, stepping backwards after being startled from the sudden hug, returns it with a pat on the girl's back, chuckling softly.
"You feeling alright Mabel? You haven't been having any more of that Smile Dip stuff again, have you?" he asks, pulling away from Mabel with a knowing smirk.
Mabel responds with her own silly grin, jumping back and holding her hands behind her body embarrassingly. If only she could tell her uncle just what had gotten her so giddy, so filled with girlish glee. But, as she pulls a finger up to her lips, chewing idly on her nail, Mabel giggles at the possible embarrassing conversation about her new feelings concerning her brother. The thought made her blush softly, her face heating as she stares up at Grunkle Stan, staring back with an inquisitive gaze.
"Yeah, I'm fine." the girl replies with a toothy grin, whipping her hand back behind her body, "Just excited I guess!"
Grunkle Stan continues to stare at her for several minutes before dropping his head in a soft sigh.
"I'll never understand you kids." he says, deadpanned and unamused, "Anyway, I got a movie all cued up in the VCR; it's a classic! Used to love watching it when I was a kid."
Mabel was intrigued. She wondered what kind of movie Stan had chose for them, though she hoped it was something with lots of colourful animals, being her favourite genre of entertainment. However, knowing her Grunkle, it was probably some boring old man mystery movie, the kinds Dipper liked to watch. Either way, it would be infinitely better with him by her side throughout. With an appreciative smile, Mabel nods her head.
"Thanks Grunkle Stan, sounds great." Mabel replies, turning and walking slowly to the couch, letting her hand slide across the wooden table top next to the seat dramatically.
"Do you want anything from the store?" Stan then says, stepping out of the lounge room into the kitchen.
Mabel's head whips around, her heart fluttering at the notion Stan had suggested.
"What? Are you going out?" she asks, just to be sure.
"Yeah, I gotta pick up some stuff for dinner." Stan calls from the kitchen, opening the fridge to peer inside, "How about pasta?"
The thought of Dipper and herself watching a movie together again made Mabel feel all warm and fuzzy inside, but watching a movie alone? Together? That made her excited. Trying to remain composure, Mabel forces herself to answer.
"Uh, yeah! Pasta sounds great!" Mabel calls, sitting down on the couch with her knees together and her hands balled into fists, bouncing on her knees in anticipation.
As Stan exits the kitchen again, Dipper arrives at the bottom of the staircase, stopping quickly to avoid running into him. After a moment's pause, Dipper awkwardly slinks around Stan standing in the doorway, hopping down the step into the lounge room and walking over to the smiling Mabel, patting the seat next to her.
"Hey Dipper, pasta for dinner?" Stan asks, causing Dipper to spin around at his name.
"Uh, sure thing." he replies, his brow raising in amusement.
"Great! I really like pasta!" Grunkle Stan shouts in a grainy voice, whipping his arms up in front of him like a robot to try and elicit a giggle out of Mabel, to great success.
Dipper shakes his head and turns back to sit down on the couch, Mabel, still calming down after laughing so hard, throws herself against her brother, holding her arms down in her lap and resting her head against his shoulder.
As Dipper looks down strangely at Mabel, Stan chuckles to himself, watching the two get reacquainted, before turning and opening the front door.
"Stay out of trouble!" he calls as he exits, the door slamming soon after.
Dipper smirks and pumps his shoulders, knocking Mabel's head up again, making her sit upright. With a fake pout, Mabel reaches forwards and takes the remote off the coffee table, pressing the button to start the movie.
"So, what're we watching?" Dipper asks, kicking his legs up onto the table and dropping his arm on the couch armrest.
"One of Stan's movies." Mabel replies, staring at the screen as she lowers the remote again, glancing over to Dipper quickly to answer.
"Ah, okay." Dipper replies, smiling at her briefly before returning his gaze to the screen, watching as the opening credits start to roll.
As she leans back into her seat, Mabel can't help but watch Dipper out of the corner of her eye, focusing on every little movement on his face as the movie begins. His eyes flicking left and right, scoping the scene, and his lips pursing softly as he swallows, his Adam's apple bobbing in his throat, seductively pushing upwards before falling down again, and a soft sigh being released from his mouth.
Forcing herself to focus on the TV, attempting to hide her blushing red face under her arm, Mabel snuggles against Dipper, who responds by lifting his arm up to rest against the girl's shoulder lovingly. With a longing sigh, Mabel resigns to simply enjoying the movie with her brother, pushing all thoughts out of her mind.
The first scene of the movie opens on a dark city street, the style of the buildings lining the road and the saxophone playing in the background giving the impression of the 1940's or so. The streetlights reflect off the pools of rainwater on the tarmac, the faint sound of police sirens sounding in the distance. The scene fades to a shot from the side walk, a beautiful woman wearing a heavy fur coat clicking her heels as she walks past.
The twins watch as the woman approaches a building, a faint orange glow coming from inside the faded glass window. Opening the creaky wooden door, she steps inside, the camera cutting to follow her in. The interior was very reminiscent of the old styled offices from the 40s, the leather seats and brown wallpaper barely visible in the dim room. The woman, not stopping to look around, marches past the first room and down a hall, eventually coming to a doorway.
The scene cuts to inside the detectives office, an old man in a large leather armchair facing away from his desk, staring out the window on the far wall, through the shutters, as he smokes a cigar. The man wore a dark trench coat and a fedora, perfectly fitting in with the constant saxophone playing over the movie. The door opens and the woman enters, causing the man to spin around in his seat. The camera cuts to watch him face her, his cigar dangling from his hand. The man asks what the woman was doing in his office, and the camera cuts to her replying that she 'needed to talk with him.'
Just when Mabel was beginning to lose interest in what appeared to be a boring detective movie from the old people times, the woman takes off her coat, revealing a stunning and very revealing red gown, showing off her busty cleavage. Resting against him, Mabel could feel Dipper tense up at the sight, becoming embarrassed himself as the woman seductively saunters over to the man in the movie. She leans over his desk, the camera panning around behind the man to watch as she dangles her breasts over the desktop, fluttering her eyes cutely. The man seemed unfazed however, and simply stands dominantly, declaring that there was 'nothing he could do.'
For the next ten minutes, the two Pines twins watch eagerly as the two argue, the woman growing more desperate each passing minute, telling the man that he was responsible for putting her husband in jail. The man shouts back at her, telling her that she was never in love with him, and that she was a 'tramp', a 'bimbo.' All throughout, Dipper's blush grows larger and larger, now realizing that the movie Stan had selected mustn't have been exactly as he remembered it. The two had been told about Stan's past, and his impossible to please father, it wouldn't be all that unlikely that he wouldn't care what his son watched when he wasn't looking, and so Stan found this flick, which he saved after all these years. Instead of focusing on the story, Dipper could only try to rationalize why they were watching the movie in the first place, his theory plausible, but still not explaining why Stan would forget such a... sensuous opening scene.
Mabel, however, was blushing for a whole other reason. As the woman on screen throws herself onto the man, grabbing his jacket and becoming more hysteric, causing him to respond by grabbing her around the waist and pushing her aside, all Mabel could do was stare, watching as the hardly concealed breasts of the woman jostle around, shifting under her gown. Instead of being embarrassed, Mabel was getting excited, in a way that she hadn't felt for a long time. Her "girl parts", as she liked to refer to them as, began to heat with her face, the argument turned fight playing out in front of her stirring her loins. And she could tell Dipper was having the same reaction, the tell tale sign of a bulge in his pants giving it away. Mabel has had to deal with the teenage boy's erections in the past, always teasing him or being grossed out by him becoming aroused at the worst of times, but in this new light, and with her conflicting thoughts about him, Mabel... became fascinated, her attention turning to Dipper's pants rather than the screen.
However, her spell did not last long before the suggestion scene turned sexual. For some reason, possibly because of the constant and now provocative use of the saxophone, the woman had become ravenous, throwing herself against the man with vigour, clawing at his coat to rip it off. The man replies with tugging at the woman's dress, pulling it free right there in his office, exposing her lacy dark purple bra underneath. Both twins jump as her breasts were exposed, Dipper shocked into flinging his hand over his crotch, and shifting away from Mabel. The cries and moans from the television become louder and louder as Dipper leaps up and scrambles for the remote, barely managing to shut the movie off before the woman had enough time to drop her dress and reveal her panties.
Dipper, blushing intensely and shivering from the shock of embarrassment, slowly lowers the remote, staring at the blank screen. Mabel sits up too, blushing just as hard, but struggling to keep a straight face from the desire to rub her most intimate parts. The cries of the two lovers fresh in her mind, it only flamed her hidden desires in her heart for her and her brother, ones she knew were so terribly wrong, but just felt too good to ignore.
"Uhh... well." Mabel says with a cracking voice, finally breaking the silence, "That was... um. A little, awkward, huh?"
Dipper slowly turns his head back towards his sister, sitting slanted on the couch, half laying down from her previous position nestled against him. The absent body warmth on his side creating a tingling sensation as he stares dumb-faced at the girl, finding it difficult to find his voice and face what they had both seen.
"I-I... Mabel, I- We need to tell Stan that-" Dipper starts to say, before being cut off.
"Dipper, it's okay, it was just a movie, there's no need to..." Mabel says softly, her voice slowing to a stop as she stares back into Dipper's eyes, which were flicking left and right. Slanting her own eyes, Mabel now notices how Dipper was casting fleeting glances down at Mabel's extended legs, her smooth skin showing under her short skirt, resting lightly on her now mature, wide hips. Dipper was no stranger to looking at women on the internet in the past, but after watching the beautiful woman in the movie be ravaged so intensely, all the while sitting next to his... beautiful sister...
As Mabel reaches a hand up to console her brother, he swiftly pulls away, jumping up off the couch and turning to her.
"No, Mabel-" Dipper quickly says, before suddenly stopping. Mabel was staring at him. Whipping his head down, he spots the large bulge in the front of his pants, causing the boy to gasp and quickly cover himself with his hands. Unable to muster a plausible excuse, and under the intense stare of his sister, Dipper clenches his eyes shut and turns to run out of the living room, letting out a frustrated groan as he bolts around the corner and up the stairs.
"Dipper, wait!" Mabel calls, before hearing the door slam upstairs.
Mentally cursing herself for being so stupid as to stare at the obvious embarrassment her brother had, Mabel flops back on the couch, her arms falling to her sides as she lets out a disappointed sigh; disappointed in just how quickly Dipper ran away from something as simple as a boner. It was a sexual movie, after all, even she started to feel the arousal build inside her.
However, thinking about it, Mabel wasn't just becoming hot herself because of the man and woman going at it in his office, it was because she was with Dipper, and thinking about him all the while. All day she could think of nothing but her brother, and even going into the movie, she didn't stop. And something about that first scene, as evidence by her damp panties, sparked something in her brain, some barrier between her and her brother that she wanted to break through for a long time, finally reached.
But whatever had made Dipper run out of the room so fast, even if it was nothing, Mabel had to know. Furrowing her brow and putting on her 'serious face', Mabel stands and marches out of the living room. Approaching the stairs, she nervously stares up, thinking about just what to say.
Lifting her left foot onto the first step and taking in a deep breath to boost her confidence, Mabel begins to ascend, determined not to let a silly movie ruin their summer together.
