"Well, Mari, I--" You began, only to have the words die in your throat as Jenna's hand shot out, clutching your midsection and squeezing your lungs flat. It was such a fast action that you didn't even have time to blink.
"Actually!" Jenna exclaimed a bit loudly, silencing your response. She lowered her voice as she withdrew her hand, bringing your slightly crushed body along with her. As she stood back up from leaning over the table at you, she discreetly let you tumble into her palm, where she then hid you completely by clenching her fist.
Your sister, ever the perfect actress, convincingly looked sheepish. "Sorry for shouting. I'd, uh, actually like to ride the waterslide with Matt and Ashley a few times. Just like old times." She said, in reference to how frequently she'd take you on trips to The Oasis with Ashley and her (often against your will) when you were younger.
Mari bit her lip, hesitating. "Really? I kinda wanted to--"
"It'll only be for an hour or two!" Jenna splayed out her hands, apologetically shooting down Mari's prepared complaint. "Please? Obviously, Matt'll want to spend most of the day with you, Mari. Can his big sis take him for a bit first?"
Lauren put a hand to her chest and smiled warmly. "Oh, I love seeing you two get along so well, Jenna! Little Matt is lucky to have a sister like you."
Mari's brow furrowed, but after another moment of internal deliberation, she consented. Easing her features into a small smile, she shrugged her shoulders. "Sure, Jenna. Just don't wear the cutie out before I get a turn splashing around with him."
Jenna grinned appreciatively. "Oh, trust me, Mari. Matt's going to have a whole day jam-packed with fun!" She looked at Ashley. "Ready to hit the waterslide, Ash?"
Ashley thrust out a confident thumbs-up, even an action as simple as that causing her titanic, thinly-clad tits to jiggle erratically. "Sure thing, Jen-Jen!"
With the first few hours of the day decided (wholly without your consent, as you tried to reform in your sister's iron clad grip), the five women went their separate ways. Mari headed off with her mother, probably to compete to see who could swim the most laps, and Lauren headed off to catch a nice little nap and tanning session. Jenna and Ashley, meanwhile, approached the fairly sizable waterslide, which was already bustling with a considerable line. The two girls entered the line, catching up with the waiting period at about the half-way point to the top.
Jenna finally relented in her grip of you, and laid her palm flat to allow you to reform. The sun was already fairly scorching, and you and Jenna's palm began to sweat during the several minutes it took you to reform. Once you had reformed, you glared daggers at your sister, who playfully stuck her tongue out at you. The cruel smirk in her eye made it clear she knew full well that she was screwing with your plans for the day by taking you from Mari.
"Thanks for agreeing to tag along with us, bro." Jenna said in a fairly positive tone of voice, but you caught the passive aggressive taunt in her inflection. After all, you'd hardly 'agreed' to anything.
Before you could retort with your own barb, Ashley grinned excitedly. "Yeah, Matt! You're the best, and we'll totally have so much fun together!" She smiled at you, exuding radiant happiness. Her bubbly excitement was just enough to cool you off from your frustration with Jenna. Pushing aside your negative thoughts, you managed a smile and returned it to Ashley, earning you an adoring look from the curvaceous redhead.
Just then, looking at Ashley, it dawned on you in this close proximity just how ludicrously immodest her bikini was. Her top and thong were genuinely just bits of hot pink string that were stretched to the seams to fit Ashley's mind-bogglingly well-developed body. Two little pathetic triangles just barely covered the girl's soft nipples, and her thong was more like dental floss being shoved between her meaty cheeks and crotch. Try as you might to not stare, it was a losing battle, especially when Jenna and her moved a few more steps up the line, and Ashley's curves jiggled and swayed.
The heat of the sun wasn't only affecting you and Jenna, either, as Ashley was quite visibly sweating up a storm, despite how early in the day it was. Her pale flesh glistened with a sheen of sweat, and droplets rolled tantalizingly down her breasts and stomach. Her skimpy top kept slipping as well, so Ashley had to constantly pause to adjust the straps of her bikini, the act of doing so putting on a show to everyone around her as her bodacious breasts squished together against her hands. She also kept picking at her thong, clearly a bit annoyed at how much it wedgied up her crack.
Jenna smirked wryly at her best friend. "You're going to snap your bikini into pieces if you keep picking at it, Ash. It's barely holding up as it is."
Ashley chewed her lip. "Yeah, I know, sorry. It's, like, probs my favorite bikini of all time, but it IS a few years old, and..." She trailed off. "I don't think it'll fit for much longer."
Your sister sighed theatrically. "That'd be a shame, huh? Wonder what we'd have to do if it snapped today, and you were left without a suit..." She let the statement linger ominously, and your blood ran cold as soon as you realized the implicit threat your sister was leveling at you.
The subtext sailed right over Ashley's head though, as the redhead merely continued picking at her stringy bikini. One of the strings caught on her fingernail, and she accidentally pulled it away, revealing her full left breast to the world. Your eyes bulged from their sockets and continued to stare as Ashley hastily fixed her mistake, then locked eyes with you. She froze for a moment, a light red hue lighting up her freckle-dappled cheeks, before she flashed you a sultry smile and added in a wink. You hastily looked away. Jenna laughed softly to herself.
Just then, your sister moved another step closer to the top of the slide, and you forgot to brace yourself on her palm (of course, it also seemed like Jenna was slowly tilting her hand to make it harder for you to hold on, but you might've just been imaging that). Regardless, you let out a quiet yelp as you tumbled from your sister's palm and smacked down onto the hard wood of the stairs. The impact slightly squished you, but that didn't concern you as much as watching your sister move a step further away from you...and the next woman in line step right up onto you!
With a startled cry, you pried your squished body free and hobbled away, just barely avoiding the woman's gigantic foot slamming onto the step. You hastily reformed as fast as you could, then put your upper body strength to good use by scaling the step back up to where your sister now was. You climbed onto her big toe, then relaxed and caught your breath, a near-tragedy narrowly avoided. Back in relative safety, curiosity got the better of you, and you turned to look at the woman who had nearly pulverized you.
Your first observation was that her platinum-blonde hair was quite visually striking, a side-swept stylish bob adding to her allure. Your second observation was far less chivalrous. The woman was beautiful, more so than almost any other woman you'd seen before in your life (save for Mari, of course). She appeared to be around your age, and she was tall, with richly tanned and flawless skin, and piercing blue eyes. She was abundantly curvy, probably nearing your mother's level, but her height distributed her weight to all the right places, achieving a super model aesthetic. Her purple bandeau bikini top clung to her massive breasts in an irresistible way, and her sexy high-cut bottoms similarly emphasized her hughmongus, perky rear.
Jenna, feeling you on her foot, lazily shook you off, then turned to follow your gaze and glimpse the woman behind her. Jenna let out a tiny gasp, and you broke your view of the woman to gaze up at your sister. From the awed look in her eyes, it wasn't hard to tell she was immediately smitten.
The woman caught Jenna staring, and smiled shyly. Jenna flushed bright red, managed a quick smile back, then looked away. You took a moment to laugh at your sister's embarrassment, as it was so rare to ever see her flustered.
You also took a moment to realize that the other woman still hadn't noticed you, which meant you weren't quite safe yet. You quickly crawled away from Jenna's toes and up to the final platform where you board the waterslide, joining Ashley. Jenna joined you two after a moment, as the last girl of the group in front of you was motioned down the slide.
The bored, sleeping-looking lifeguard, yawned and then spoke. "Okay, next!"
Jenna and Ashley looked at the beckoning slide excitedly, then glanced down at you. You stared up at them, and realized they were waiting to see who you wanted to ride with, as you had never before gone down a waterslide by yourself, since it was so obviously a safety hazard.
1) You choose to go down with Jenna, placing your trust in your sister to keep you safe on the ride down. Is that a good decision?
2) You choose to go down with Ashley, putting all your hopes on the curvy redhead keeping you secure amongst her assets for the ride.
3) You decide to be brave and go last, letting both Jenna and Ashley take a trip down the slide before you. However, when it is your turn next, disaster strikes!
