As soon as she climbed out of the pool, Inez smiled. "It was close, Anneli, but you weren't quite--"
"We're going again, you smug asshole!" Anneli jabbed a finger at your cousin, completely consumed by her competitive nature. "And we're not stopping until I beat you, alright? You're going down!"
Inez's eyes briefly flicked to the thin, strained sight of your looped limbs around Anneli's hips, then looked back at your best friend. "Whatever you want to do, Anneli. I'm game."
"Then get ready to get fucking demolished, Inez!" Anneli shot your cousin a cocky grin, then set off in a sprint for the slide queue once more. As she ran, her massive glutes jiggled and jostled, wobbling about in a manner that results in waves of fleshy cellulite smashing and slamming into you over and over, her ass cheeks chewing on your body like her booty was trying to consume your entire existence.
While the two women waited in line, Anneli rested against the metal handrail, enjoying the warm feeling of the sun-heated metal against her water-dappled booty. And yet for as much as she enjoyed it, you hated every second of it. The heat was twice as intense for you, burning your skin and broiling you alive. Worse, the more it dried Anneli's booty, the more your best friend began to sweat, her naturally heavy sweat outload kicking up again, and drowning you in the viscous liquid. You gave a feeble twitch, begging Anneli to stop this madness, and to your shock, Anneli actually let out a gasp, like she'd felt you.
And she had, and a blush of shame instantly flamed across her face. Tentatively, Anneli glanced backwards at her fat booty, shoved up against the metal guardrail. She really had temporarily forgotten you, and felt great embarrassment in doing so. She'd really slipped into her unfocused competitive mood, the rest of her mind naturally too lazy to focus on other things.
I'm sorry, Allegra. This wasn't supposed to go on for this long. Anneli silently thought, hoping you could pick up on her contrite apology. I swear, once I beat Inez, I'm off to the shop, no matter what she tries to say. And hey, maybe you're used to being squished by my booty, so this isn't too bad? Regardless, I hope you enjoy this nice heat from the railing, and wish me luck at winning!
Smiling again, Anneli went back to leaning against the railing, not even realizing the reason why her usually swampy ass was so barren was because your absorbent affected body was greedily, and disgustingly, sucking up all her waterfalls of sweat.
At the top of the queue, Yesenia gave Anneli a sympathetic smile. "Maybe...try leaning back more this time, being more aerodynamic?"
Anneli shot her a thumbs-up, and then slammed powerfully down onto the slide, her ass wobbling about, and your floss-like form vanishing ever deeper into its crushing embrace.
*****
One entire hour later, and Anneli emerged from the water at the slide's pool like a goddess of the ocean, loudly and proudly cheering with excitement. After countless runs down the slide, she'd finally managed to beat Inez. And though the score was, of course, wildly unbalanced in your cousin's favor, Anneli didn't care. She'd finally conquered her opponent, finally found triumph on the waterslide, and was so overcome with joy that she couldn't think of anything else other than celebrating. Literally, couldn't think of anything else, a fact demonstrated pointedly by her pulling herself out of the pool and then adjusting her bikini top and bottom, ramming your body tightly against her asshole.
You were only barely holding onto consciousness at this point. Anneli's booty had, over the course of about two hours now, subjected you to what normally would've been two weeks worth of crushing, squishing, and sweat. Your entire being ached, your mind struggling to retain its grip on awareness simply due to how much of your world was now becoming Anneli's ass. Your whole body, save for your looped limbs pushing into the supple curve of Anneli's hips, was consumed by your best friend's ass. All of you was trapped in darkness, pinned by her massive doughy buttocks, caked in her sweat, and marinating in her stench. It was misery incarnate, and you couldn't even muster the energy to twitch for her attention.
By the third race down the slide, it was clear you'd slipped entirely from Anneli's mind, and her booty kept pounding you so fiercely that you couldn't gather the strength to try and get her to remember her bikini bottoms weren't just a normal swimsuit, but were you. Each time you tried, Anneli's butt either smashed you into oblivious, or your bestie subconsciously clenched her ass cheeks and crushed you that way. Her mind was becoming more and more focused on Inez's competition, and far less on you, something that happened often with someone as easily distracted by entertainment as Anneli. Worse, Anneli's laziness meant she often never bothered to focus on remembering things, especially while she was distracted. Left to her own devices, you stood a very low chance of Anneli remembering you on her own now that she'd forgotten about you.
"Congratulations." Inez said, pulling herself out of the pool. "You did well, eventually."
Anneli teasingly gave your cousin the middle-finger. "Don't be jealous, bitch. I'm just the queen of the waterslide, that's all!"
"I won every other time." Your cousin pointed out.
Anneli scoffed. "Well then, I'll just have to dominate you on every other slide we ride today! Come on, what's next?"
"You'd like to do more?"
"Hell yeah! I'm having so much fun!" Anneli pumped her fist. "I don't often like exerting this much energy, but god, when I get this charged up on competition, I never wanna stop. Reminds me of my eSports days!"
Your cousin cocked an eyebrow. "I'll gladly spend all day with you, Anneli. First, though...is there anything you're forgetting?"
"Huh? That's a weird question." Anneli frowned. "What the fuck would I be forgetting? I don't exactly have pockets on this thing." Anneli laughed, and jiggled her bikini top and bottoms for emphasis (once more grinding you against her anus). "My purse is in the locker room. Is that what you meant?"
Inez appraisingly eyed Anneli, and then your poor, tortured self. She then casually shrugged. "Nothing, just curious. Let's go to the next slide."
"Awesome." Anneli grinned.
She and your cousin then set off for their next slide, with Anneli's ass wobbling with her every step, and you jostled about and squished between her buttocks all the while.
1) Anneli goes the rest of the day not remembering you, and you endure countless hours of booty-based suffering.
2) Shockingly, Anneli remembers you just a short while later, and finally rushes off to the swimwear shop to buy a replacement and free you from your torment.
3) Shockingly, Anneli remembers you just a short while later, but she's on the opposite end of the park from the swimwear shop, forcing her to keep wearing you. She swears to try and be more gentle with you.
4) During a later waterslide, when Anneli splashes down into the pool, your looped limbs finally can't bear Anneli's weight anymore, and the knots she tied snap. You drift free from her, and float away in the water, leaving Anneli stunned, and too flustered to think about anything other than covering up her nudity. You're left behind, and are snatched out of the water by someone else.
