From Chapter 14 of The Dark Ocean by Rann [link]
I highly recommend this story! The picture above is from the paragraph I've posted below XD Oh, and Shego's wearing makeup in order to blend in, hence the flesh tones.
Kim paused on the sidewalk and just looked around from behind her own slim silver sunglasses. It was unlikely anyone would recognize her... her face had changed, her body shape a little as well. And most people that had actually been acquainted with Kim Possible wouldn't have figured her for a snug, plain white t-shirt, Smarty Mart blue jeans, and a well-worn, thin black leather jacket. They certainly wouldn't expect her to have a tattoo on her neck.
Shego was dressed similarly, save in a black t-shirt and denim jacket, and with black cowboy boots instead of sneakers. She'd also topped it off with her black cowboy hat, and as she followed Kim's gaze, she fiddled with the brim a bit.
"Think we're obvious?"
"No... I kind of wonder if anyone even remembers Kim Possible or Shego," Kim said rather wryly.
"I meant, do you think we look like a pair of huge bull dykes?"
"Oh. ... Probably."
