Walking was pain, standing was pain, existence was pain. Sitting was less pain, until Dipper needed to shift a leg, at which point it quickly shot back up the list to be a top pain contender. The pain was less than it had been when they were in the parking lot, bearable now and not life-ending, but he certainly was starting to wish he’d stayed home where all the icepacks were and potholes weren’t.
Still, Mabel’s suggestion of “cooling off” in the colder wave pool was a good idea, and after he’d popped briefly into a restroom to make sure nothing looked irreparably damaged, he joined them out in the shallows, wincing as the first wave it but then sighing as the cool water soothed the pain.
He also finally had a chance to appreciate her swimsuit as he waded into the water: It was a new one, a deep cherry red, with a simple front but a strappy back and a little enameled metal cherry charm dangling from one of the bikini strings. Little blue-glitter cherries adorned all the non-strap bits of fabric, shimmering in the water and noon sunlight. He could hear her laughter before he could even see her, and seeing her was like watching a mermaid as she splashed and swam around, letting out an excited “Dippingdots!” before diving to surface next to him.
He tried not to stare below her neck, as he didn’t want to flare up the pain, but he felt a stab of hot annoyance and anger as he saw the gazes of a few other guys in the wave pool looking over his sister as she swam by.
Wait, anger?, part of him reflected. You were never angry at her boyfriends, so why would you be mad at some strangers?
Weeelll, that’s not exactly true, part of his memory chimed in. You did kinda detest Aiden. And Justin. Heck, even Mermando, and that was a one-time fling. He sighed internally, coming up with mental justifications that he just as quickly shot down. One solid point remained standing after a few minutes of cooling off and reflecting: You want Mabel to be happy, and she’s never been happy, really happy, with anyone but, well, you.
They splashed around there for a minute as Dipper waded deep in thought, before the majority of the throbbing subsisted. After giving him a questioning look and getting a painless and enthusiastic nod in return, Dipper followed Mabel to the first of the rides of the day. Given that it was used briefly and for medicinal purposes, he hadn’t checked off the wave pool on his mental list of rides yet, and filed it instead in the ‘Incomplete’ folder; If they were going to come to a waterpark, he wanted to make sure they were going to do it right and hit every one, since it might be another year, or more, before they could come back again.
“The Mountain” was a simple ride, and was little more than just a series of slides; Nothing fancy, with a trio of different slides of different complexity, interweaving like a drunken braid before ejecting near the bottom of the pool. The line was fairly short for this one, and within a few minutes of standing around on too-hot cement and trying not to stand with his thighs together, he and his sister were standing at the entrance for the ‘Black Diamond” slide.
Mabel was about to go sliding in first, when Dipper had a horrible thought of her getting stuck or slowing down, and him ramming her head back on the freshly-tender injury. “Uh, how-howsabout I go first, huh Mabes?”
She looked at him confused for a solid fifteen seconds, and then glanced down before quickly glancing back up, her face filling with understanding. “Oh. Ohhh. Definitely!” She took a step back, and made a royal bow gesturing him towards the rushing entrance of the slide.
Dipper gave her a thumbs up, which she returned with finger pistols. He took the opportunity to feign death at her finger-pistol assault, collapsing into the tube with his arms crossed and nearly losing his balance in the process. He slid down the tube and his world became a blue blur. There was the swish of water to left, right, and left again, sending him at one point uncomfortably close to the raised lip of the slide, before after a few more seconds he was spat out into the waiting pool.
He had barely managed to slow down and get his feet on the landing pool floor, when he hears“Cowabunga!” from behind him. Before he can dodge, Mabel comes scooting out of the tube, almost skipping across the water like a stone, and thumping into the back of her neck. He grins for a moment, and she gives him the command “Up!” like an imperious camel driver.
He strained, for a moment or two; He’s been working out, but genetics dealt him a hand of blown raspberries when it came to strength, and even actively working to try and build muscles beyond his old noodle arms was almost entirely futile.
Almost, but some degree of that work paid off, and he lifts her into the air with a whoop from them both, eliciting bemused smiles from nearby park-goers. Soos waves at them from a nearby corn dog stand, and Dipper begins walking towards him, still piggybacking Mabel. The feeling of her soft thighs against the side of his heads suddenly has those thoughts bubbling back up from earlier, and then the realization of her bikini-clad mound directly behind his head had him breathing shallowly and his vision starting to spin pleasantly.
Then there was a stab of familiar pain as the injured dick tried to reawaken, and he stopped short, groaning in pain and his shoulders giving a momentary shake as Mabel asked “Whoa, Dippers, what’s wrong? You ok down there?”
He groaned again, quieter this time, but she quickly dismounted, in the process sliding her chest against his bare back for an agonizing second. The stiffening pain throbs again, and he hobbles over to a rock to sit down as Mabel follows behind, repeatedly asking him what’s wrong.
He gives her a weak shrug and equally weak smile. “Oh, nothing. Don’t worry about it.”
Mabel immediately dismisses his feeble attempt at misdirection with a narrowing of her eyes. She sees him double over as the pain surges one last time before receding as he begins to soften, and as he watches her eyes go from confusion to surprise, and-Is she blushing? Oh shit, she’s totally blushing.
His sister began to flush across her ears and face; It’s faint compared to the pink toasty sheen the sun has provided so far, but he can see it, and he breaks eye contact before she can say anything. She gives a single awkward chuckle, and says “Well, erm, hokay. I, uh, I guess I’ll wait over here until you’re ready to, to tally-ho to the next ride.”
She sits over at a nearby bench, still watching him with concern in her eyes, and after another minute or two of rest Dipper regains his breath and stands up, taking a few experimental steps. The pain has mostly abated, and while there’s still a minor twinge, it’s better than it even was immediately after the wave pool. Mabel gives him a look, which he can’t tell is more anxious or worried, and he gives her a thumbs-up and a grin.
She breaks into a broad smile, and comes over next to him as they wander down the path. “Man, you’re like the energizer bunny: You just keep going.” Dipper grins, but before he can stop it an evil bubble forms and hijacks his mouth, saying “Oh, you haven’t seen anything yet.”
He stops in his tracks, going slightly cross-eyed as his noble-monkey-brain catches up to what his debased-lizard-brain made his completely-impartial-mouth say. Mabel has stopped as well, making a single noise that the can’t tell whether it’s a squeak from her shoes or her mouth. His bile begins to rise in his throat as he worries that she’s about to call him disgusting and run away from her dirty-minded twin, but she just says “Uh…huh,” like she’s puzzling over a particularly difficult knitting pattern rather than what just spilled out of his mouth.
After a tense few moments, she looks up at him, her face still slightly flushed but giving him a toothy smile. “Well, ready to try the Whitewater Terror?” He smiles back, letting out an unconsciously-held breath, and before he can reply Soos comes running up.
“Ah, doods, doods, check it out!” He shows them a pair of little cheap water pistols, with a huge “WEEK OF WET!” logo emblazoned across the water tanks. Before they can say anything, he shoves them into Mabel and Dipper’s hands, saying “Here doods, take ‘em as like souvenirs or somethin’. I got lotsa tickets, heh, so it’s like no big deal.”
The twins accept the gifts with a smile, as Soos looks back up towards the arcade area before looking back to them. One of his pockets overflows with tickets from the arcade, and he says “Alright doods, I’ll catch up with you in a minute. Melody loves teddy bears, and there’s a talking Bear-O doll she’d probably love! Catch you later!”
Before he can say “Wait, Soos, I’m not sure that’s a good-” Soos is out of earshot, running towards the arcade. Dipper sighs, and smiles as Mabel shrugs and says “Well, hey; Maybe after getting to see Bear-O come to life at Hoo-Ha’s, she might want a talking version of her own?”
They maintain eye contact for a long moment, before they can’t keep a straight face any longer and both begin to laugh. They begin walking towards the next ride, and his sister hands him her water pistol, both of which he shoves into his surprisingly-spacious trunk pockets.
As they walk, his hand brushes Mabel’s, and she takes Dipper’s hand, sending a surge of warm goosebumps up his arm that he hopes she doesn’t notice. It’s nothing they haven’t done as twins before, but for some reason this time it’s making him feel, to use a Mabelized term, “fluttery,” in a really, really nice way.
Maybe, just maybe…she might feel the same way?
