Nabiki gets the truth the next morning and tricks Ranma into being sluttier.

Ranma woke up the next morning with a lewd smile on his face, which sadly didn't last more than a few seconds as Nabiki screamed it off. "Wake up Saotome!" she shouted down at him, already fully dressed for the day. "Get up, get presentable, and..." her eyes suddenly drifted to Ranma's hair, then his breasts. "Why are you still a girl? You had plenty of time to splash some hot water, grow your dick again and everything." Then she caught a glint of light in Ranma's cleavage, reached down, and looked for a second time at the gold coin Ranma had been carrying in there. "'Become What You Seek'...what's that about?" Then, she suddenly looked more closely at Ranma's face, as if seeing something new for the first time. "Wait a second, you look different...spill the beans, or I tell my father about how much money you owe me."

Feeling half-awake and suddenly trapped, Ranma couldn't stop himself from sputtering out, "I-It's magic or somethin', changes you based on how you act, I think. When I tried acting more...more slutty to give out flyers, the coin started making me into more of a slut, and now I'm all...like this, and I can't use hot water to change back."

Once Nabiki had digested that word salad, her mind set to work. For perhaps a moment, maybe two, she considered helping Ranma return to normal. He was (probably) going to be her brother-in-law at some point, and it would be courteous to help him out. But that plan quickly went out the window. After all, Ranma's girl form was easily in her top five most profitable assets, and more girl time meant more money. And that wasn't even counting how much her revenue would go up with the whole slut thing. Before Ranma knew what she was doing, Nabiki threw the coin back into his cleavage and said, "You're a slut, Ranma. Be more slutty, become a total whore."
