Chat some more. (poop)

In your old world, you wouldn't had stopped to chat with some random person. But after watching this woman ride someone's cock out in public, pee where she sat, and was fully nude made it feel more weird if you didn't strike up a conversation with her, especially since she was interested in chatting with you.

The train stopped at a station. Remembering the rout to get to work, you have four more stops before getting off.

"N-no problem," you say as nonchalant as you can, trying not to be awkward, "I wasn't in the mood, late to work and all." Felisha seemed to accept that answer with a nod.

"Tell me about it. My boss gets on my ass when the train is running slow, but he can be fucking his secretary in the elevator until lunch. It really does kill the mood." She says as she parts her legs, letting a stream of pee arch across the car, landing on the seat across and adding to the liquid already in it. That's when you notice that you too need to pee. Not only that, but breakfast seems to want to get off as your stomach grumbles. You squeeze your legs together and slide your hand over your abdomen, remembering that you've been bottomless this entire time but not really important. As Felisha finishes her pee, she then notices you struggling. "Are you okay?" she asks with concern on her face.

You try to play it off, that is until you feel your intestines ache. It seems that not only did the world change, but so did you in that you now have to go more often than before. This wasn't something you noticed back home, but now out in public, you had some reservations. Not to mention the fact that you didn't poop at home probably means now you're not gonna take an average shit. Feeling the constipation you look up at Felisha with a pained look, "No, I was running behind that I forgot to poop this morning." Without hesitating, Felisha got from her seat, the urine dripping off her as she moves to stand in front of you. She then bends down and lifts your legs, exposing you anus and pussy.

"Have you been sick or eaten anything different than normal?" She asks in a serious tone. You're however confused on what she's doing and try to answer her until you feel her finger your ass. You yelp as she plays with your hole. "You seem tight," she says, "are you relaxed right now?" It's hard to say considering she's got a finger in you. She then pulls her finger out of you, now covered in shit. Instead of disgust, Felisha starts to examine the poop on her finger, smelling it and noting the color. "It looks normal, and smells normal." She says standing up, she wipes her off on her butt cheek. "You just need to relax. Let your sphincter loose." Even after all of that, you have a look of concern on your face. This is the first time you'd be evacuating your bowels outside a toilet bowl. But this was a different world where toilets don't exist and doing your business where ever was the norm here. So why was it hard to loosen up and just do it?

Felisha, seeing your concern, immediately sat down in your lap. Her body up against yours, you can feel her pussy rubbing against your own. "Don't worry," she whispers, "I'll poop with you." After she finishes, she starts to push out a log from her anus. Felisha moans as her excrement piles up on the floor between your legs. You also feel her start to pee on your vagina, wetting and warming it up.

For some reason, this does relax you. Soon you feel your own shit flow out of you and into your seat. Everything seems to dissolve into a haze as you're now feeling relived, warm and now horny.
