“Rachel?”
	“Rachel!”
	“Rach-”
	“Racheeeeeeeel!”
	“Jeez Mia-”
	“Raaaaaaaacheeeeel!”
	“You don’t have to be that loud!”
	“How else is she gonna hear us?” Unbeknownst to Mia, the bear in question had heard them the entire time. In fact, said bear very much wished she didn’t. 
“Mmmfh.” Rachel groaned, cradling her midsection while taking refuge behind a wide tree. Shortly after her sister went off for new pervy adventures a familiar pressure befell her stomach, the kind that usually occurs after a long day full of hearty meals. But Rachel didn't expect it to occur so soon, and especially not while she's stuck outside who knows how far away from the nearest bathroom! 
Rachel ventured back into the forest soon after that, hoping to just walk off the feeling but it only grew worse with a terrifying speed. And now, there she was squirming against a tree. Dang it, it must've been all that granola! So much fiber, it was like eating sand with chocolate chips, but Casper kept saying they needed to keep their energy up! 
“O-ooh…” She stiffened at the feeling of a squeeze down below. Moments later a silent, too moist poot bubbled out of her. “U-uugh.” She shuttered, it ended with a heavier, more sour pressure pressing against her ring that made her thighs press together. She pouted looking at the roll of toilet paper in her right paw, Casper left it with her ‘just in case’ but dang it, she didn’t want there to be a case!
Ppprrrlrlppt… “Ah!” Another wet string of rippling gas slipped from her clenched rump. Dang it, dang it, she couldn't hold it anymore, she couldn’t believe she had to do this! Oh gosh…
“Rachel!”
“Raaaaaaaacheeeeel!”
And she needed to make it quick! Rachel’s paws fumbled with her belt buckle, precariously holding the roll up on her index finger. Her hips so badly wanted to fidget feeling another pressure prodding her tailhole, and she wasn’t so sure it was just gas again. “S-stupid belt…” She mumbled, instead tucking the toilet paper under her chin as her newly freed fingers got her pants open in a few agonizing seconds. Moments later, she begrudgingly pulled them along with her panties down to her knees and settled into a squat for the second time within an hour. Pfffffffssssssttttt…
Rachel seized up as that silent stream of deadly gas hissed from her, internally something solid moved lower to take up the freed space. She couldn’t stop shaking, her body was demanding a push, and she could feel the air tickling her bulging ring. She tried to tell herself it would be just like peeing, and…t-that wasn’t so scary. She just needs to…give it a…l-little…push.
“Augh…” A moan just barely above a whisper slipped from her throat as her tailhole ever-so-slightly yawned open. The crowning head of her waste wasn’t that wide, being the relatively fresh result of this morning’s breakfast it was an easy, pleasant inch or so of moist, soft dung that felt all too eager to shoot out of her. 
She shivered, gritting her teeth, and the piece of waste poking from her rump shivered with her. She was too nervous, too unprepared from how quickly it would slide out of her. But, she's fine…it's not so bad. She just needs to take a deep breath…and give another pu-
“Raaaaaaaacheeeeel!”
“Aa-” Rachel flinched and slapped her paws over her own mouth. That was Mia's voice right behind the tree!
“Rachel?” No please. Rachel’s heart jumped as she heard footsteps approaching. She barely even started to scream in her head before Mia popped around the tree. “Rachel!” 
And yet, that shame was instantly replaced with a sucker punch of shock. “Mia?!” Her dear little sister was as naked as the day she was born!
Mia covered her mouth, her eyes going wide as a high pitched giggle tumbled from her belly. “You’re going potty again!”
“Where are your clothes?!”
“Casper said I could take my clothes, and you said to do whatever Casper says!” Mia cupped her little paws around her mouth and yelled out. “Caaaaaaasper, I found Rachel!”
	Now there’s that shame. “Mia no!” Rachel rasped.
	“Oh! Hi Rachel!” Casper called back, his steps turning towards them. “Are you Ok?”
	“Yes, I’m fine! Don’t come over here!” The bigger bear practically had steam coming out of her ears.
	“Huh? Why not?”
	“She’s going potty!” Mia eagerly answered, much to her sister’s chagrin.
	“O-oh.” The sound of a chuckle in Casper’s voice nearly killed Rachel. “Well…let me know when you’re done!”
	“O-oh my god.” Rachel’s knees shivered, the stress of the situation may have reminded her body of the task at hand. Her ring quivered as another pressure rose. “Mia please, g-get out of here!”
	“But why?”
	“B-because, ah!” An airy, zipper sounding fart pushed out of her as that eager waste started descending once again.
	“Hehe, you tooted!”
	“M-Mia…aaaagh…” She stood no chance against thrice the daily fiber recommendation. Rachel closed her eyes and leaned her head back as soft load burst through, making a messy, squelching exit into the world. It happened so fast, in the matter of seconds 6 inches of light brown, moist scat rocketed out of her and coiled on the ground, ending with a silent but surprisingly refreshing hiss of gas. She panted out, her whole body glowing warm with overwhelming relief, and shame.
“Woah!” Mia went wide-eyed. “You pooped! …And it’s stinky.” She giggled, pinching her nose and playfully fanning the air.
“I can’t believe you saw that…” Rachel mumbled in a daze. Even as sisters, there are some things that should never be seen.
“Mmmm…” Mia rubbed her bare bear belly, the subtle pushes under her waist had been growing ever since her first squat in the woods with Emily. All that fiber was having a similar effect, only packed tighter in her smaller tummy. Her foot drew circles in the dirt, feeling an envious pucker at her back door. “Rachel, can I poop too?”
“H-huh?”
“Can I, mmfh, poop too?” She repeated, already squatting down.
“No!” Rachel squeaked instinctively. Despite what she had just done, and was still squatting over, the sight of her sister getting into the same position still sent chills down her spine. Yet, there seemed to be a silent agreement that all social barriers had long been trampled.
“I-it’s c-coming.” Mia strained as she held onto her sister’s shoulder, her face going huffy. The solid weight started to course its way down her walls without even a push. She channeled her remaining resolve to boost her voice. “Ca…Caaaaaasper! D-do you wanna, ung, s-see me poop? Agh.”
“No!” Rachel blurted, somehow even more aghast.
“Um…it’s Ok Mia, maybe next time!” The fennec boy politely declined from somewhere in the trees.
“Aww…” Mia didn’t have much time to ruminate on her disappointment however, as moments later the pressure in her colon reached an intense pique. She shut her eyes, tightened her grip on Rachel’s shoulder, and pushed it along with all her might. “Auuuuuugggh…”
Rachel watched on, horrified, but also morbidly curious. In tandem with the force of Mia’s grip, her sister’s pink exit bulged outward and a more firm, darker brown head spread it open at the height of Mia’s grunts. Just 2 seconds and 3 inches later, a fresher, more loose texture surged through her ring, the viscous flow interrupted by quick poot blasts, that resulted in a more broken pile on the ground. Similar to Rachel, her movement was finished as quick as it started.
“Haaaa…” It was like Mia’s entire body deflated. Her grip loosening, her muscles relaxing, her eyes going dreamy, and a weak drizzle of urine sprouting from her slit. Her anus winked with weak puffs of gas, today’s breakfast and yesterday’s dinner had left no stragglers, she was truly empty. It left her with a pleasant, drowsy relief, enhanced by the refreshing forest air on every nook and crevice of her body. It only took a few moments however, for Mia to regain her bearings, and have that cubby energy come back. She looked at Rachel, giggles brimming her lips. “Rachel I pooped!” She chirped. “I pooped, I pooped, I pooped, I pooped!”
“Yeah…you did.” Rachel couldn’t stop a smile from growing on her face too. She was so stressed about this from the moment the hike started, but here she was, she and her sister both with matching stinky piles under their scut tails, and…everything’s Ok. Well, it’s still pretty gross but, it wasn’t the end of the world. In fact, it felt pretty good!
“And you did too!” Mia said with a bounce, leaning over to wrap her arm around Rachel’s shoulder as a side hug.
“I did.” She chuckled, her sister’s so silly. “...But we’re not gonna tell mom and dad about this.”
“Ok!”
“Uhhh, are you guys done?” Casper’s voice called out.
Oh. Remembering his nearby presence made Rachel shiver. “W-we’re almost finished.” Her voice faltered as she called back.
“Yeah, we’re gonna wipe our butts now!” Mia followed up. “You wanna watch?”
“Mia!”
Well, Rachel thought that pooping outdoors would be the apex of her gross adventures on this hike…turns out it was not. It was actually wiping up after the fact that made her feel the most squick. “Oh my god…” She groaned, her back stiffening as she dragged an intensely soiled wad of toilet paper over her twitching ring. She didn’t dare look at it as she let it fall on top of the pile. Why did it have to be so wet this time? Why couldn’t there be sinks in the forest?!
“Ewwww…” Mia droned with an amused titter as she did the same. Though at least she had comparatively less crack to clean than her bigger sister. “It’s all slimy in my butt!” She announced, being brave enough to inspect the state of her tissue.
“Mine too…” Rachel added, gritting her teeth as she started a fresh swipe. In due time, their tissues started to return clean, and their rumps felt less swampy. Their paws unfortunately were a completely different story without a bar of soap for miles. Rachel made a mental note that they were both taking baths the second they got back.
“Done!” Mia announced as she simply stood back up. Rachel on the other paw wordlessly dropped her final wad, pulling up her panties as she rose to her feet. “You’re gonna keep your pants on?” Mia asked with a light innocent tone. “Everybody else at the lake is naked, it’ll be more fun if you didn’t!”
Rachel paused as she reached for her pants. She had already done the absolute worst she possibly could in the woods, going naked should be easier but…she still shivered thinking of all the eyes. “...I’ll see.” She said, pulling her waistband up to modesty.
“Aww.” Even if her sister wouldn’t fully embrace the lake lifestyle, Mia still felt excited to show her all the new thingies she's discovered. But first… “Caaaaaaaaasper, come see the big poops we made!”
“Mia!”
“Ummm…you can tell me about it on the walk back!”
“Aww…”
Paw-in-paw, the ursuline sisters traveled a short distance back to the path to meet with their group leader again. Though, Rachel was particularly surprised to see the state of dress he was in. “O-oh, Casper.” Her face warmed as she spotted the pantless boy. His patterned boxer-briefs were…cute, and the thin fabric held a nice grip on his shapes. The following sound of his voice reminded Rachel where his eyes were.
“Yeah…I’m doing it too.” Casper said with a mirrored blush.
Mia broke off from Rachel to hug her new boy(who's a)friend with a bubbly titter. “Casper’s cute right?”
“Aww jeez, you’re too sweet Mia.” The humble fennec pat her giggling head.
“Don’t be a perv Mia.” Rachel said, though the scolding sting of her voice was replaced with a playful shyness. Similarly, the usual stern disapproval on her face now looked like a flustered smile. A boy’s never hugged Rachel like that before…nor given her head pats…especially not without pants! Is this what lake life is like?
“Come on, come on!” Full of little sibling excitement, Mia released her boy(who’s a)friend to retrieve Rachel by the paw. “Let’s go back to the lake so Rachel can see the other boys too!” 
“Ok, Ok!” Casper chuckled as Mia re-wrapped her arm around him and started pulling him along too. Someone was clearly excited to be the leader for once…so excited that her paw ventured a bit low on Casper’s back. “M-Mia, that’s my butt!”
“Oops, hehehe!”
