Dipper’s face was ashen, his breath coming in short bursts as he saw Mabel, a mantra in his head repeating Oh no, oh no, oh god, oh god. Her expression was that of puzzlement, and then a slightly-open mouth and wide eyes revealing a deep emotional hurt rather than the twisted-up expression she made when something physically hurt.
He was not expecting that face, but he couldn’t help but stare at her blood-covered shoulder. Mabel noticed the direction of Dipper’s stare, and as a lifeguard came running up saying “Hey miss, you need to come over to the first aid station,” she saw that her upper shoulder was a mass of red.
Dipper could see her purse her lips and reach back to poke her shoulder, and when a few tentative pokes produced nothing more than a minor wince, he forced himself to relax. It’s just a flesh wound, not a life-threatening thing.
The lifeguard also looked relieved at Mabel’s calmness and obvious lack of pain, and in a voice lacking the worried urgency from a minute ago, points them towards a squat, white building trimmed in red. “Just head on over there and Avery can get you some stuff to clean that up. Don’t worry about it; The water usually makes injuries look worse than they really are.”
Mabel nods, and Dipper thanks the lifeguard and takes her hand as they walk over towards the building. He can feel her arm and gait is stiff, worried, and he remembers the way she looked at him when he’d first noticed her shoulder.
Her voice breaks the awkward silence. “Musta banged up my dumb shoulder on the dumb guardrail earlier. Sorry for being a bleedy mess right now,” her tone dropping as she continues to stare at the pavement. Raising her hand up, Dipper kisses her on the back of her hand, and she looks up at him, smiling warmly as he can feel her relax alongside him.
Then his sister begins convulsing in giggles, stopping for a second as she tries fruitlessly to cover her giggling mouth with her hand before they squeak out the side into a belly laugh. Dipper smiles, confused but glad to hear her happier than he’s heard her in months. She hasn’t been sad, per se, but her excitement most months seems muted compared to those amazing summers in Gravity Falls.
She holds up her hand by way of explanation, and Dipper’s eyes widen as he can see that more than a little of the watered-down blood from her shoulder has covered her hand. “Uh, not trying to crimp your style Dippinsauce, but-” she breaks into a fit of giggles, “-But I think I might have some lipsticks you should use before you jump all the way to Blood Red.”
Dipper blushes in embarrassment, chuckling as he wipes off his lips with the back of his hand. The worker at the first aid station, a beaming brunette lady who looks about the same age as the twins’ mom, comes bustling over to the counter near them. She notices Mabel’s injury straightaway, and tutting she gives her a mock finger-waggle.
“Did someone sneak into a ride that was too big for them?” she scolds lightheartedly, the lanky teens going along with the joke and shrugging apologetically. Avery, as her nametag confirms, begins scuttling between a few drawers, and after a few minutes presents them with a bandage, some sterile gauze, and a bottle of rubbing alcohol.
Mabel’s cheeriness takes an abrupt dip, and she lets out a forced solitary laugh as she looks at the bottle of alcohol. Her voice says with a hint of a waver, “Hey now, I don’t think it was quite that bad. I mean, hey, what are water fountains and soap for, eh?”
Avery, to her credit, gives Mabel a look of sympathy, but says reluctantly “Normally, yes, but there’s enough people going in and out here that there’s all manner of nastiness that could bring you down with an infection, even with the chlorination.” Dipper grabs the bottle, and gives his sister a reluctant smile.
“Well, unfortunately I think I have to agree with the lady Mabel. I can at least help get you cleaned up, though,” he says, putting a bit of lightness into the end. Mabel still looks reluctant and somewhat scared at the thought of the pain, but nods.
Avery points them towards a back area of the aid station, essentially an open porch with a couple sets of padded benches and privacy curtains hanging to keep bugs and prying eyes out. Dipper and Mabel both thank Avery, and head back there. The only other person in the porch area is a young child, judging from the sniffling cries, but as Dipper holds a curtain open for Mabel to enter, they can hear a parent saying “All right now Henry, let’s get going home. You want ice cream on the way back?”
The sounds of the now-excited child fade, leaving Dipper and his sister alone on the covered porch with only the background buzz of conversation and splash of the rides in the distance. He begins opening the bottle of antiseptic, when Mabel puts her hand on his arm to stop him.
“Shut your eyes,” she says breathily, and Dipper can feel his heart hammering against his chest as trills of electricity begin racing down to his shorts and across his bare chest, where the gentle breeze is teasing his few-but-proud chest hairs and drying the water leftovers from the last ride.
He does as she asks, and can feel her get up, and take a step towards him. His heart is pounding in his ears as she stands on tip-toes, right in front of him and-
Wipes something across his forehead?
He peeks open an eye as she begins quietly singing the opening lines of The Lion King, and then opens and rolls his eyes, sighing heavily as he realizes what she’s done. Mabel breaks down into a fit of giggles as she steps back, and says “Sorry brobro; I wanted to make sure I took advantage of the opportunity before I got cleaned up..”
He groans, but smiles back at her and licks a thumb to wipe off the smear of symbolic blood on his forehead. He turned his attention back to the bottle of rubbing alcohol when Mabel took a step forward again. He nearly dropped the bottle in shock, looking up to meet her gaze. Her warm eyes were melting, enveloping, and he smiles. He’s trying to think of what to say when-
She leans forward, and kisses him.
Dipper can feel his body respond, the heartbeat in his ears returning to form a raging white noise that drowned out all sounds of water and conversations and anything else in the park that wasn’t his abruptly-ragged breathing, Mabel’s warm breaths on his chin as she breaks the kiss, the breaths sending a flush all the way down his chest, and the quiet rush of wind that was rustling the curtains and giving him goosebumps, and doing the same to Mabel judging from the little shiver she gave.
She looks at him, and he can see some of the concern and anxiousness that he saw earlier, but that melts away into excited eagerness when she sees the corners of his eyes crinkle in a smile. He reaches to pull her into a second kiss, this time savoring her flavor, the vanilla-bean glitter lipgloss, the warm taste of her mouth as her tongue darts out to run along his lips and plunge into his. She lets out a little muffled happy noise, partway between a moan and a happy sigh, and he can feel himself give a similar noise in return.
He pulls her close, and begins to run his hands over his sister’s shoulders. She shivers at his touch, but then begins to run one hand through his messy hair as the other feels along his back, digging in slightly with her nails as he cups her ass and pulls her towards him.
He can feel himself stiffen, but with a mischievous grin he pulls her close this time. Mabel notices his expression, and breaks off the kiss to start to say “Dip, what’s so-” before he hugs her close to him, his cock straining against the thin material of his shorts as her eyes widen. A second later she lets out a little appreciative “mmm” as her hand reaches down from his back to cup him and feel his hardness through the suddenly-inconvenient trunks.
He groans, and leans down to kiss between her warm breasts, running kisses up and down from her neck to her sternum and feeling himself get even more excited as he hears her breaths become faster and shorter. Dipper shifts aside some of the crimson, sparkly material covering one of her breasts, revealing a little pink areola with an erect nipple, goosebumps ringing all around it.
However, before he can do anything more than lean forwards in preparation for a kiss on the revealed breast, the sounds of the aid station door opening interrupts him, causing him to jerk back. Mabel hurriedly lets him go, frantically rearranging the swimsuit as she and Dipper both take deep breaths so they don’t sound like they just ran a marathon. Their faces flush, Mabel gives him a cheeky grin, but her eyes widen and she goes stiff when Avery’s outline can be seen against the white curtain.
“You kids coming along ok in there?” she calls, and Dipper lets out a little sigh. Mabel replies, saying “Yup, we’re doing great. Almost done over here, and we’ll bring over the alcohol and leftover bandages once I’m set!”
Avery replies with just a simple “Okiedokie then! I’ll be right over there if you need me!” before her outline fades and the aid station door can be heard again. The twins make eye contact, and begin giggling quietly at their narrow escape.
After they catch their breath, though, Mabel gives the alcohol bottle a long look before looking to Dipper. He nods solemnly, and takes a deep breath to brace himself as he douses some of the alcohol onto a gauze pad. He can feel her shoulder tense, and he begins dabbing the set of small cuts with the end.
She hisses through her teeth, before letting out a gritted “Ow. Well, that wasn’t so bad afterHOTBELGIANWAFFLES THAT STINGS, THAT STINGS A LOT! OW. OW OWOWOW.” under her breath. Dipper tenses in sympathy with her as her shoulder shakes, and he murmurs “Oh god I’m sorry Mabel. I’ve almost got it, I think, just one more spot,” as he hurries to get another soaked pad ready. She tenses again, and this time says nothing, and instead hisses again through her teeth before letting out a little “Eeep-ergh-errrgh,” letting out a shaky breath as the pain fades.
Dipper gets a bandage stuck over the cuts, patting it gently, but putting a hand on her shoulder as she goes to get up. “Uh, Mabes, you still look like a murder victim. Gimme a sec to wash all that off,” he says as he bundles up the extra bandages and alcohol and steps out to the aid station.
Avery gives him a questioning smile, and he just sets the supplies back on the counter, saying “I think this will do the trick. Is there a water fountain or something I can use to get the rest of the blood washed up?”
She nods. “Yup, right over there behind the curtain area is a little washup sink. Should do the trick?” Dipper nods, and thanks her again before walking over to the sink. He couldn’t help but notice that she was decidedly less chatty than when she was first helping them, and his cheeks began to burn as he realized she might have realized what they were doing. Calm down Dip, calm down. Take a breath; You’ve never seen her before, you’ll probably never see her again, and for all she knows, you’re just a boyfriend and girlfriend and nothing more.
He took a long breath to calm himself, and a little part of him noted excitedly that the idea of Mabel being his girlfriend sent a warmth to his core, one that he couldn’t even remember having when he and Pacifica or Candy were dating. Calling out “One sec, Mabes,” he crossed around the curtains to the sink.
Well, “sink” was a stretch. It was actually just a sturdy plastic bucket with holes drilled through the bottom, and bolted to a post with a faucet head sticking out the top. Still, the faucet water served his needs, and he wet a stack of fresh gauze before coming back in to help Mabel.
He nearly dropped the gauze: His sister was standing, but her bikini top was unlaced and laying on the bench. She dropped her arm from her chest shyly as he carefully put the curtain back into place, and he could hear her say in a quiet murmur “Well, I thought this might be a bit easier to clean up, so there’s not a bunch of complicated strappy doodads to work around?”
She was trying to keep it lighthearted, but Dipper could hear the uncertainty in her voice. He nodded, murmuring a choked “Yeah, that’ll-that’ll work great,” as he struggled to keep coherent thoughts.
He stood next to her, and she turned, showing her bloodstained back to him. He began to work carefully, rubbing with the cold water and making her shiver, but cleaning all traces of blood from her shoulder, back, and arm, careful to avoid the fresh bandages. She shuddered again, letting out a little happy noise as he ran his empty hand along her arm, gently grabbing her delicate wrist before lifting her hand back so her could give it a trio of little kisses, making her giggle.
He ran his hands back down, leaning forward so his breath was along the nape of her neck; She shuddered, moaning quietly as he began tracing up her stomach and chest, cupping her breasts and giving them a light squeeze. At that, she turned her head and caught his mouth in hers, kissing him deeply, passionately, muffling her groans of pleasure against him as his hands continued to explore her.
He could feel her knees start to go weak as his hands began travelling back down again, running past her stomach, down her side to run along her hips, and then back inwards and up her thigh. He had nearly reached the base of the cherry fabric when the sounds of a crying little girl cut through their pleasant reverie, and Dipper couldn’t help but groan, Mabel echoing his disappointment as they broke apart.
He could hear Avery say “My, what a big splinter for such a little girl! We’d better get that looked at right away!” as Mabel put her top back on, and he bundled the soaked gauze and tossed them into a little wastebin before stepping out of the curtain, followed a second later by his sister.
Outside was a disheveled-looking older man, evidently the father of the little girl, who was wearing a fluorescent-pink polka-dot swimsuit, water wings, and was holding one hand like the bones in it were shattered. Dipper could see a tiny brown fleck on one of the fingers, and gave her a sympathetic smile. He was about to move on when Mabel’s hand stopped him.
In a murmur, she said “Hey Dip, looks like someone could use a pick-me-up. Do you suppose Soos would be overly upset if we donated one of those water pistols he gave us?”
Dipper shrugged, and retrieved the one from his right pocket. He handed it over to Mabel, who went to go give it to the little girl, saying “Well, that looks like a mighty nasty wound there little lady!” as she crouched down to look the little girl in the eye. The girl nodded solemnly, tears visible in her eyes, but Mabel, with an air of formality, presented her the water pistol. “Well, only the bravest of Water Warriors can wield a weapon such as this. Do you think you’re up for the task?”
The little girl let out a “YES!” and little squeal of excitement as she grabbed the gun, and Dipper could see the girl’s father smile in relief. The father reminded the little girl “Now what do we say?”, resulting in her nearly tackling Mabel in a hug with a little squeaky “Thank you sparkle lady!” before she followed her dad and Avery towards one of the curtained areas.
Mabel stood up, a wistful look in her eyes, before her brow furrowed in mock concentration as she said “Hmm, Sparkle Lady. Y’know Dip, that might be the next official title of Lady Mabelton if she ever gives up her throne.”
They both laughed, and Dipper gently grabbed her hand, giving it a loving rub with his thumb as they walked. However, he felt a sinking feeling as he stuck his hand in his pocket, feeling something soggy and lumpy in the pocket under where the pistol had been stowed.
Oh no. Oh nonono.
