Pretty much no, really.

Erin snarks loudly. "Well, you could leave town and do it like all our ancestors did it. In the woods, with bugs creeping up your..."

"Shush, Erin. Abby is not used to our civilized ways. Give her some room, and time to adapt. Dear Abby, you can take your own time. I don't want to rush you. However, you MUST empty your bowels here, before you are allowed into the next room. This is messtaurant etiquette, and extremely important for hygiene."

Abby appears to sob for a moment, but the group pressure weighs down on her. She squats down, facing away from the street, but with her knees firmly together. Then she grabs her ass and begins to excrete. She is on a much more solid diet, unless I misjudge what she presses out of her. Her feces are clumped together in little chunks. They fall down until she is finally done. I bite my tongue, and don't dare to tell her that her unusal way of shitting has attracted some passerbys to stop and check her out. A glance and headshake to my side makes sure that Erin also doesn't bring this topic up.

"Well done!" I finally applaud her. "You have managed shitting in polite society. Just so you know, NOW we're doing the peeing."

Rahid nods, he has stopped swaying after finishing his dump. While perfectly still otherwise, a thin stream of urine emerges from his erect cock and splatters into a wide arc, landing just short of my feet. With a frown, he slightly adjusts his position and the hot flow reaches me and caresses my feet playfully. I glance to check on him, he has a marvelous tight and round cockhole to have such a defined and distinct emission. If he were at all interested, I'd love to mount him later, and check if his ejaculation is as precise. Too bad that he only has eyes for Abby, even now after she humiliated herself. Erin apparently thinks just the same, with regards to Rahid's display. "Wow." she says.

Abby just stares blankly ahead, and so I decide to just stick to my usual routine with Erin, and have it all over with. We eat out together quite often, and so we are used to just squat opposite each other, and to grab at each other's peehole. Erin's soft hand gives me instant relief, and I spray her first, causing her to giggle immensely. Given all my varying and sometimes difficult clients, I have gained a very wide aperture. There is no other way but spraying, for me. The highest-reaching droplets even hit Erin's chin.

But Erin is not responding in kind as I tweak her familiar vagina. "Are you holding ba..." is all what I manage to say as her warm piss meets my skin. Her aperture is comparably tight, and I close my mouth quickly enough to only get my face soaked by her first spurt. I shudder in delight as she tickles me so nicely, if only this glorious moment would not... Just a second later, her pressure is gone, and the stream that passes her vulval lips cannot even reach me at all. I facepalm. Erin rarely pranks me like that, but I probably deserve it, given how I always spray her from chin to ankle.

"Hey, it's early" she defends her poor perfomance.

Considering our passerby audience - just three people outside, probably debating if it is too early to get some stuffing - it is probably for the best that Abby is facing away from the display window. The look of absolute and utter disgust on her face is very dark and ugly.

"Well!" I claim, pushing the button to flush our business away. "That was that, Abby. We have emptied our bowels entirely, and now we are going to wash up." Abby looks up and a spark of hope begins to glimmer in her eyes.
