Se heads to the stalls to eposit your remains, finding an unoccupied on and popping herself down atop the toilet, humming cheerily to herself.

"Oh.... I'm sssso sssorry girlsss..."

She cant help but overhear someone talking to themselves a few stalls over, but mostly ignores it. Focusing on getting her own business done. A few small lumps plopping into the water below her.

"I did try to ssslow myssself... pleassse, just come out a little sssmoother."

The catgirl finishes, tail flicking merrily as she cleans up and heads out of bathroom, only pausing by the mirror to quickly acknowledge the cute additions you had made to her butt. Then, she is gone leaving your remains spiralling away down the sewer.
