(Chapter originally written by PhoenixStriker)
Rio was fully aware that she was missing context. Clearly, something unexpected had happened while she had been away, and it had something to do with Matt trying to apply tanning lotion to his mother and ending up squished to her right butt cheek. Obviously, Lauren was unaware of what had happened, though if Rio had to guess, Lauren was also presumably responsible. Rio knew Matt to be an accident-prone young man (who she firmly believed brought many of his mishaps upon himself through carelessness), but in this scenario Rio couldn't see how Matt was possibly to blame.
And yet...Rio hesitated in reaching out to help him. She could see Matt's eyes on her, and almost pleading look on his flattened face. He obviously wanted her help...and something about that rubbed Rio the wrong way.
Rio's heart often ached for the struggles tinies went through on a daily basis, but more than that she felt deep regret that so many tinies never had the chance to face their struggles with enough strength and preparation. It's why she'd adopted such a strong stance on forcing tinies to help themselves, face their weaknesses, and fight for their own safety and independence. Rio was confident her methods (though some could argue a little strict) were the best way to help tinies grow to be the truest version of themselves.
So, seeing Matt look to her for rescue somewhat annoyed Rio. How many times had she seen Matt in this exact position, and how many times had seen gone out of her way to rescue him. Too many, apparently, if Matt was still unable to avoid this situations, and if he still sought outside help instead of trying to escape on his own. Yes, it was true that Lauren was one of the least attentive and observant women Rio knew, particularly around tinies, but she was the poor's mother for crying out loud. If Matt couldn't stay safe from his own mother, how would he fare around the outside world? Around her own daughter, the boy's girlfriend?
Wiggling her booty again, Lauren threw Rio a concerned look. "Uh...Rio? Could you please help?"
Rio snapped to her senses, spared you a final look she hoped conveyed her intentions, then turned to Lauren. "Of course, sorry. I zoned out for a second." She cracked her knuckles. "Don't worry, Lauren. You'll have that perfect tan in no time."
As for you, you stared up at Rio while she'd been having her internal monologue, wondering what was taking her so long to finally save you. She'd obviously seen you, and your pleading look hadn't been subtle. Why hadn't she peeled you free already, or even moved to do so in the first place? Yeah, you knew Rio could be strict with her whole 'strength training' philosophy for tinies, but surely she had to know you weren't to blame for this. Lauren was practically a walking disaster around you and other tinies. It wasn't your fault!
And yet, as the bronzed Brazilian lowered a hand to scoop up a generous glob of tanning lotion, you realized with horror that somehow, in someway, Rio must've come to the conclusion that this incident was your fault, and so she wasn't going to do a damned thing to save you. Rather, she was going to force you to save yourself...after sealing your fate first, apparently!
Silently screaming, there wasn't a thing you could do as Rio's firm fingers pressed down into Lauren's doughy right butt cheek, and slammed down onto your face.
Rio wasn't one to go half way on things, and she proceeded to put 100% of her energy into lathering up every last bit of her best friend's bodacious booty in tanning lotion. She vaguely realized coating you in tanning lotion would most likely make your escape harder, but Rio still felt that that was a justified obstacle that would only impress her further if you managed to escape on your own. So, without any leniency, Rio prodded and kneaded Lauren's cheek, spreading the tanning lotion out evenly across your mother's body.
As she did so, her strong fingers squeezed and squished into your body, grabbing at bits of your malleable form and contorting and stretching you as she worked at your mother's booty cheeks. In minutes, you went from being a man-shaped sticker on Lauren's behind to being a vaguely humanoid tan blob that took up a full several inch diameter across Lauren's right butt cheek. Rio's unintentional molding further flattened you out across your mom's flesh, which only made your body feel less strong and capable of reforming at such a stretched size and smushed density. Whereas before you'd felt reformation was minutes away, now you felt like that goal of escape was much, much further.
Rio eventually finished, but the damage was done. Though your own skintone was a shade lighter than your mother's, you looked more like a blobby birthmark on your mother's otherwise pristine ass cheek, rather than a trapped tiny son begging for help. The most visible part of your body that remained were your eyes, capable of nothing more than blinking rapidly as your heart raced and your panic levels spiked.
They spiked even higher as Rio stood. Lauren mumbled some sort of thank you, already halfway to falling asleep, and Rio spared you a final glance. Her expression was as frustratingly unreadable as possible, and you yet again cursed fate for forcing you to fall victim to another of Rio's 'tests'. You were ninety-nine percent sure Rio liked you and approved of you as a boyfriend for Mari, so you wished each day she'd just accept you for who you were and stop trying to push you to your limits of strength and independence. Yes, her intentions were well-grounded, but if you could be frank, she didn't know how awful being a tiny could be.
But, it wasn't as if you could voice any of those objections at the moment. You could only watch the single woman capable of freeing you saunter away to swim some laps in the nearest pool, leaving you to your fate. Determined to prove Rio wrong in looking down on you, you instantly started trying to reform. But, after fifteen minutes of no progress, you had to start facing the reality that this would be an hours-long escape, at minimum.
Rio had thoroughly mangled your body by mashing you flatter and more stretched out along the surface of your mother's right ass cheek. Not only that, but the tanning lotion effectively formed a sort of sealant layer as it dried in the hot baking rays of the sun, further reducing the efficacy of your reformation attempts. Thirdly, said hot baking sun was sapping you off your strength by the minute, and causing both you and your mom to sweat. Of course, your sweat was manageable, while Lauren's giant beads of salty viscous liquid were large enough to cover your entire body, nearly drowning you in sweat just minutes after Rio walked away.
Still, you persisted, even with the deck stacked against you. Even as the heat threatened to knock you into unconsciousness from sheer exhaustion, even as your mother's sweat waterboarded your smeared body, and even as countless oblivious people walked by (many stopping to gawk at your gorgeous mother's jaw-dropping derriere), you pressed on. To your utter shock, you found yourself gaining more and more control over your body, and reformation actually seemed within your grasp.
Then, Lauren let out a cute groan, and rolled over onto your back, a peaceful smile on her face as she started to tan the front of her body.
That simple movement ruined everything, and you knew it as soon as it happened. The world rolled nauseatingly on its side, and then you were buried beneath the full weight of your mother's ass as she settled onto the towel. Her quivering cheek came to a rest with your entire body pinned under its girth, your face shoved into the hard tiny fibers of the towel. More and more sweat poured freely over your body from this position, as the pressure atop you multiplied ten-fold. The heat rose as well, as did the first hints of an odor wafting from your mother's butt crack beside you.
Any progress you had made was instantly reverted by Lauren rolling over, as you were freshly crushed into nothingness. Knowing that escape was now literally impossible, all your drive and strength left you at once, and you gave up. Exhaustion claimed you, and you passed out.
Over in the pool, Rio turned to see Lauren lying on her back. Shaking her head, Rio sent another mental encouraging thought to your plight, then promptly pushed you from her mind and resumed swimming.
