Erika decided to attempt to ignore the rumbling, the pressure kept growing. She must have appeared to be struggling as she tried to hold it in. "Are you alright, honey?" her mother said. "Yeah, I-" Oh no. Her panties began to feel full, the feeling was oddly pleasurable, extremely relieving. She couldn't help but groan slightly, as she both peed and pooped at the same time. A yellow liquid began to leak from her chair, landing on the ground as the room began to stink.
She discovered that she had changed as well, whenever she peed or pooped it felt extremely good to her, her mind blanked out and she couldn't think.
