Something she thinks triggers the gold coin, and she changes again, getting a tramp stamp.

The dangerous thing about the gold coin, is that once you fully accept and embrace what it's done to you, it changes you more. It's never satisfied with the present, always yearning to push boundaries further. So when Paula fell in love with being a slut, as Charley left the bathroom, the gold coin glowed once more. This time, almost all the activity was mental. Her own career, her hobbies, faded away, becoming dull and lifeless in her mind. Now, sex was the best thing in the world. More knowledge of sexual positions, of how to become a camgirl, of how to become a professional sex worker, all of it filled her head while also increasing her libido by several factors. The only outward sign of change was the addition of a butterfly tattoo on her lower back, her own personal tramp stamp.

The activation of the coin didn't go unnoticed by Paula, pulling it out to stare at it as the glow began to fade. Running over what had changed, it hit Paula how different she was now. Her job, most of what she'd done for years now, it all felt like a chore, something to get through so she could get to the good stuff, like sex. Well, honestly, mostly just sex. If she'd seen someone who thought this way beforehand, Paula would have thought they were pathetic, or a weirdo, but from the inside it all felt fantastic. And now, she had two magic coins to make her dreams even more then that.
