(Scene: At the party, when Anna and Chloe make the first visit to the master bedroom)

[...]

Standing back up, Anna pulled her panties back up, smoothing out her skirt as she prepared to leave, zipping the backpack back up quickly.

"Let's go," Chloe said in a quiet whisper, heading for the door.

"Yeah, that line won't get any shorter," Anna agreed, "I'll just have to brave it."

"Huh? Why?" Chloe asked, stopping and giving Anna a curious look. "You can wash your hands in the kitchen."

"Oh no, no that," Anna replied, shaking her head. "I, uh..." trailing off, she sheepishly reached up and rubbed at the back of her head. "I have to... do more than just pee, this time," she admitted quietly, glancing away from Chloe.

"Ooooh, okay," Chloe said, nodding in understanding. Then, smirking, she leaned forward, holding her hands behind her back. "Why not do it here anyway?" she teased, her tail lashing back and forth deviously. There was no way Anna would agree to it, so she'd easily win this little contest in the end.

"Wh-" Anna began, staring at Chloe, shaking her head. "Chloe, I have to... you know..."

"I know," Chloe confirmed, grinning widely. "I dare you to do it anyway."

Anna blinked, and Chloe felt smug. The challenge was issued, the gauntlet was thrown down. An easy win for her, as soon as-

"Oh yeah? Well, I double-dare you," Anna retorted.

Chloe's smugness vanished briefly. She couldn't...! But she realized Anna was bluffing. She had to be. It was a trick, all mind-games to mess with Chloe. So, folding her arms, the arctic fox straightened up. "All right, you're on. You first, then," she said, putting the ball back in Anna's court. Now she'd HAVE to give up.

Anna took a deep breath, and Chloe waited for her to admit defeat. But instead, Anna reached under her skirt again and pushed her panties back down, leaving Chloe to stare, dumbstruck. No, there was no way she was going to do it. Anna was just going through the motions, trying to psyche her out... right? She was unzipping the backpack and opening it back up again, sure, but it was just an act, surely...

But, Anna pulled her entire pack of tissues out from her skirt pocket and held them ready as she assumed the same position she had been in before, squatting down and lowering her hips into the open top of the backpack, her arms wrapped around her knees. Okay, fine, she was in position, but that didn't mean she'd actually go through with it, and when she didn't, Chloe would still win.

Anna took another deep breath. No way, she wasn't going to...!

But she was. Anna's tail hiked upwards, raising up as high as it could, going still. Deep breaths and soft low grunts came from Anna, who closed her eyes. Despite her outward stoic appearance, Anna's heart was pounding in her chest.

"Annaaaaaaaaaa...!" Chloe whined, putting both hands over her muzzle, glancing between Anna and the door to the room nervously.

"I never back down from a dare," Anna muttered, and relaxed once more.

Chloe's ears pricked up as she heard Anna give a long but quiet groan, holding her tail high, followed by a soft gasp just as the first part of her solid waste fell and struck the hollow metallic object at the bottom of the backpack. Chloe still couldn't believe Anna was really going through with it, and stood perfectly still with her eyes wide as Anna took another breath, intent on finishing what she had started.

Now that she had crossed the point of no return, it was far easier for Anna to forge ahead, focusing on relaxing her bowels. Anna's soft grunt heralded another chunk being voided from her rear faster and more easily than the first, and it landed much more quietly than the first inside of the backpack, perhaps piling up within its depths. She let out a huff; despite her nervousness, she had to admit that doing something so incredibly naughty was giving her more of a rush than she had ever gotten from peeing anywhere.

A couple of breaths later and she relaxed again, surprised at how much easier such a low squatting position made relieving herself this way, once she got over her nervousness. Still, she tried to imagine that she was on the toilet rather than in a stranger's bedroom while her best friend watched in shock. Opening one eye after letting the third and smaller bit of waste fall into the backpack almost inaudibly, she saw Chloe still standing in the same place, staring in shock, her tail all fluffed up. With a little chuckle that didn't quite fully hide her own nervousness, Anna finished emptying out, dumping a couple of smaller pieces of scat into the backpack. After waiting a moment to ensure she was empty, she started pulling tissues out from her pack, still riding the surprising adrenaline rush from the moment.

"There, all done," Anna announced quietly, keeping her tail raised as she reached back to wipe. "So, where are you going to go?"

"M-Me?" Chloe asked, astounded.

"Yeah, you," Anna insisted, dropping the dirty tissues into the backpack. "You agreed to the double dare. Or are you going to try and welch on it?"

"N-n-n-no!" Chloe stammered, shaking her head. "But I, um... I don't... I don't have to, uh, -go- right now."

"Well, all right, then we'll postpone your half," Anna replied, giving herself a second wipe and letting those tissues fall in with the previous ones. Standing back up, she teased, "We'd better go get some dinner after I wash my hands. I'm gonna hold you to it, you know! Sydney couldn't escape and neither will you!"

"I-I know, I know!"

Anna stashed her remaining tissues back in her pocket, then quickly grabbed one slider on the backpack's zipper and pulled it all the way over to the other side to conceal her deed. "Until then, I'm the winner," Anna proclaimed with a wink. "Now, next stop, the kitchen..."

(Scene: At the party, Anna and Chloe's visit to the upstairs bathroom)

[...]

"Uh," Chloe began, realizing her predicament. "Could you bring me some toilet paper?"

"Sure," Anna replied, still bewildered by what Chloe had just done.

After some careful maneuvering across the wet floor, Anna grabbed the roll off the holder and brought it over to Chloe, who first dabbed a couple of sheets against her slit and tossed them down the chute, then reached up to set the rest of the roll down on the edge of the sink. Smugly, she looked up at Anna and declared, "I. Win."

Or at least, she wanted Anna to believe that; Chloe hoped that the other fox had forgotten their first visit to the bedroom. Unfortunately for her, Anna recovered from her shock and shook her head. "No you don't," she insisted.

"What? No, I totally won! That was way better than the floor in here!" Chloe protested as she started to stand up.

"Oh yeah, definitely," Anna agreed. "But you're forgetting something. Or maybe you think I forgot? Either way..." The red fox smirked, wagging her tail as she pointed at Chloe with one finger. "Are you really all done? Because if you are, I'm still the winner."

Chloe gulped. "Well I mean I..." she fumbled, trying to come up with an excuse. "I still don't really need to, um... plus, you know, we shouldn't push our luck-"

Anna wasn't having any of it, and shook her head. "Nuh-uh. I told you I was gonna hold you to it. You accepted the double dare, so either you do your half or I win by default."

"H-hey! That's not fair..."

"It's perfectly fair! You agreed to it!" Anna pointed out. "I'm not saying you have to do it. You're free to back out and let me win, if you're not as much of a bad girl as you say you are..."

Still in a half-squat, Chloe fidgeted in place, glancing around nervously. For a moment there was just quiet between them, and then Anna giggled. "It's okay, I won't tell anyone. The fact that I won can remain our little secret," she began.

And then, Chloe's tail flagged upwards and she closed her eyes, taking a breath, her hips lowering as she got back into position, this time with her back straight, one hand on the wall and the other holding her skirt up.

Anna blinked and her ears pricked up, and she heard a low grunt from Chloe just before she heard a soft thump from the laundry chute door, followed by Chloe exhaling as another distant metallic rattling sound came from within the chute itself a moment later. Once she started, the arctic fox kept going, taking deep breaths as she let her solid waste fall from her and into the chute, half of the thuds against the bottom of the door soon followed by noises from lower down – the other half seemingly avoiding striking the inner sides of the chute.

Chloe's legs trembled a bit and she kept her hand on the wall as she held the squat, some final spurts of her pee that she hadn't fully released earlier squirting over the edge of the open chute door and landing on the tiled floor instead. Chloe stopped relieving herself just as quickly as she had begun, panting for a moment, then grunting one last time as she completely voided her bowels with a final thump against the door's inside.

Grabbing the toilet paper roll from where she had left it, Chloe tore off one strip after another and folded each one up so she could clean herself the rest of the way, tossing each bundle of toilet paper down the chute when she was done with it. Once satisfied, she stood up and closed the laundry chute door, and this time slammed the toilet paper roll down on the edge of the sink, folding her arms and looking triumphantly at Anna.

"As I was saying... I. Win! For real this time!"

Anna couldn't help but admit defeat. "Yeah, I can't top that," she conceded. "You're the baddest fox of them all."

Chloe giggled and pumped a fist triumphantly. "Told you! But it's okay, being second-baddest fox is still pretty good!"
