"Jen, come on, you do that stuff through your mouth. You know that."
Jenny stared at her friend for a few seconds. Through her... really? She couldn't be serious!
And yet, as if to demonstrate her new change, Jenny felt the recently-familar urge to piss, but instead of her crotch, the feeling developed in her head. Jenny panicked, but she was still incontinent, so she ended up peeing out her mouth. It was a thicker stream than through her pussy, and the worst part was that she could taste it all.
When she was done, Jenny caught her breath and wiped the excess piss from her lips, gagging. "Gross!"
Susan shrugged. "I figured you'd be used to it by now."
