That purple atmosphere doesn't quite bode well...

"I have good news, and bad news..."

"OK, tell me the bad news first... I'm a grown-up, Judy."

"A grown-up woman, today..."

"Very witty. So, the bad news?"

"The spell incorporated a defence mechanism that I triggered. I broke it, but there were consequences. How could I word it... it's a matter of color... you see..."

"Wait. Let me guess. Red means female, like blood. Blue means male. Purple is both. This magic is making me dual-gendered or something?"

"Ah, pretty close. Basically, if any pesky sperm makes its way into your womb, the spell will become permanent. This didn't change. You're totally in control of your own desires. I fixed this bit for you. However, everyone else, especially males, will now be extremely attracted to you. And every time you orgasm, you'll have... I guess, you could call that an opportunity to switch."

"You mean, I get to choose?"

"Not really. The spell will pick whatever gender your inner desires draw you to in that particular place and time."

"Oh. That's kinda bad... "

"You'll get to explore yourself in more detail than anyone I've ever heard of, and you'll have more control of yourself, too. Spells are all about balance. This was the price for what you needed."

"I guess I should count myself lucky..." you muse.

"Well, you'll probably live some interesting hours, and maybe an interesting life... be cautious, John. And, hmmmm. I'll talk to your father if things go South, just in case he needs to deal with having one more daughter once in a while."
