Taking in the changes

Coming to think about it, you've made quite a few changes to the world. And those weren't one-off things either: between women not taking off their clothes ever, and shit now being a thing that is really common for women to wear and eat, you wonder just how deep society might have been affected.

Deciding to check out firsthand rather than granting yourself such knowledge, you take a jump from your street to the mall. As you break the pavement landing, you think back to the first time where you used your powers to do superhero shenanigans. You chuckle. Those were the days, weren't they? Well you could always wish yourself back to this wondrous time of wide-eyed exploration...
... then you remember that this was when you still had moral quandaries about calling beings into existence - or making them disappear for that matter. Nah, you decide. This is more fun.

Dusting yourself, you walk in the mall, and start looking around for unusual sights. It's... tamer than you thought. Besides the omnipresent brown and yellow stains adorning every woman's pants and a handful of ones covered in varying amounts of shit, you don't see anything unexpected. Feeling frustrated, you decide to **** the hand of fate a little: to make something interesting happen, but not something that wouldn't have happened if you just waited. Maybe you should have just sped up time instead? Eh, this works too.

As you stare straight ahead, waiting for your private public show to start, you see a couple of women walking together. Friends, from what you gather: a petite blonde named Julie, and a tall brunette named Rebecca. Sensing that those are going to be the stars of your midday show, you pause time to take a good look at them.

Julie really deserves the "petite" adjective, being not only small in stature, but in chest as well; Rebecca, on the other hand, while not much taller than a man, is on the broader side of body types, supporting a rather buxom chest. Both sports long hair, though Rebecca's is tied in a an elegant bun, whereas Julie's are free of any contraptions. You temporarily make their clothes transparent: you're satisfied to find both of their, ah, "na-nas" full of "doo-doo", as you remarked yourself earlier this day. You also note that, to your surprise, while Rebecca's mound is trimmed and clearly taken care off, Julie's is covered in a wild, nasty patch of hair. Finding this rather unpleasant, but unwilling to lean into your most reality-warping side for now, you change that just a little: her bush is still there, but now it's the kind of hairy-yet-clean-and-attractive bush you only find in porn.

Satisfied, you gradually turn their clothes visible again. You notice that those are nothing to write home about: Rebecca is sporting a surprisingly white, sleeveless shirt, a stained pair of yoga pants, simple white panties and a form-fitting black bra. As for Julie, she's wearing a similarly stained pair of blue jeans, a green top, and matching pink bra and panties.
Having gazed upon their forms for long enough, you let the flow of time resume, and start paying attention to their behavior.

"... which was an absolute steal. I mean come on, 30$ for the whole thing? And yet he dared haggle?!"
"Yeah", answers Julie, "I get you. I get the same kind of customers at the dollar shop. "Please, darling, could you make his 0.80$"? WELL NO FUCK YOU I CAN'T, it's called a dollar shop, not a "oh-you-know-we-wrote-dollar-but-we-really-meant-0.80-dollars" shop!"
"Pfft. Customers." Slowing her pace, Rebecca turns to face her friend: "By the way, are you thirsty?"
"Eh. Kinda? I mean I just had a coke, but I still have room f-wait." Julie stops walking. "Are you asking because you have to take a leak?"
"Maybe?", answers a sheepish and similarly stopping Rebecca.
Beaming with joy, Julie announces: "Well then of course I'm thirsty! You know I'm always eager to drink your girlpiss! Just please do it down my pants. It's a new diet thingy, and I've heard it works wonders."
Frowing, Rebecca admonishes her friend: "Girl, you don't need to diet. You're thinner than my arm already! Though I have to admit that soaking your pussy sounds sexier than just pissing on you."
"Hey, do you have to take a shit too? I skipped breakfast this morning, so I'm kinda hungry."
Seemingly surprised, Rebecca answers: "You want my shit for breakfast? Really? I mean, I know we're close and stuff, but that's not a thing we usually do?"
Confidently, Julie reassures her: "Yeah, well, gotta cross that line at some point, don't we? I mean, I really think of you as a good friend, and I'd really love to be your toilet. I-if that's fine with you, that is", she stammers.
"Aww", Rebecca coos, "that's so sweet of you!" Getting closer to her friends and taking her hands in hers, she tells her: "You really want me to cover you in shit, huh?" Smiling, she then confides: "Well you're lucky then! I ate chili last night and I took seconds, so I must have the most explosive diarrhea right now!"
Gasping and almost jumping in excitation, Julie excitedly says: "Really?! That's so cool! Please, please let out your hot, runny diarrhea all over my face and wipe your ass with my hair, then make it all wash down with liters of your filthy girlpi-GURK!"

Apparently unable to contain herself anymore after such a heartfelt plea, Rebecca had swiftly let go of her friend's hands, turned around, and ripped her pants open to shit straight on Julie's face. As Julie kneeled and leaned over to get as immersed in the disgusting liquid as possible, Rebecca started ripping the front of her yoga pants in order to expose her pussy to the world. Her anal stream still steadily painting her friend's face brown, she started masturbating here and there, horny to the point of no return.

As her fecal cascade subsides, she turns around, carefully readjusting her pants so none of her shit would stain the pavement - it would be impolite, after all. At the same time, she starts pissing full **** straight into her friend's face, washing down her shit somewhat. You see that Julie stretches her top so all of it would wash down inside of her cleavage; seems like that has become the norm for women being used as toilets.
Once the last few drops have finished falling down in her pants, Rebecca reaches out to Julie's long hair, and as the latter asked, unceremoniously crams it in her ass, leaving it here to soak in her crap. Aiming her beam a little, she rinses off the last of her excretions as well as possible from Julie's face, letting it become visible to the outside world once again.

Finally done, Rebecca takes Julie's hair out of her ass, wipes her pussy on another, somehow untouched strand, and declares: "Finished!".
The very caked and very happy Julie finally stands up, a mix of human waste running down her face, her shirt and slowly seeping into her pants. "Thanks! I need that. And it tastes sooo good oh my god! You ordered extra spicy, didn't you?"
"Yeah", Rebecca answers, "I can't stand eating mexican, then not having a liquid enough shit that it'd creep straight to my socks. Though I do wonder how it tastes the second time?", she teasingly asks.
Smiling, Julie plunges her arm in her top, and once she's made sure her hand is fully coated in Rebecca's chili shit, shoves it in Rebecca's mouth. Rebecca seductively suckles on her gunked fingers, dutifully licking the coating off them.
"Mmh. Tastes heavenly. I could get addicted to this!"
"And believe me when I tell you it's even better when eaten hot and straight from the source."
"You definitely have to help me with that at some point."
"Definitely."

The two friends smile at each other, then start walking again on their way to who knows where, rubbing each other's hardened clits as they do. Feeling generous, you finally tinker a bit with the situation, making both able to give multiple orgasms a minute to the other. The grunts and howls of arousal you hear from them confirms that they wasted no time putting their knowledge in action.

Focusing on yourself once more, you realize that this whole thing, while very entertaining - and educating! - to watch, also made you horny as hell.
