"I pick..."
You understand rather rapidly which creature you should become.
"I choose yo become a harpy," you say.
"A harpy, really?" says the minotaur, raising a dubitative eyebrow. "Are you certain about that?"
"Yes. At least I'ml be able to fly. That is humanity's dream since the dawn of time, right?"
"Indeed," concedes the minotaur.
"And I can look like an eagle. I prefer being an eagle rather than a sex-crazed chick."
"I understand this decision. But I can transform you only. The specifics of your appearance will be left to the gods. Or chance, if you rather see it that way."
"Will I still be a woman?"
"I do not know," admits the minotaur. "It will be a half chance either way. You'll be a harpy but what sort the decision and details are not mine to choose. Do you still want to be transformed thus? Because time is ticking and your nymph nature might take over your human mind completely and forever any minute."
You gulp. That IS scary. But at worst you might still be female as a harpy but you shall have the power of flight. That should compensate a little, right? And you ,might become male again. And above all, there's no time to lose.
"Do it, please," you say. "I'll take my chances."
"As you wish," says softly the minotaur.
The minotaur bellows his spell and the magic slams into you. You are unconscious but your body is transforming itself again, and this time again. You just hope it will be better than being a ditzy and lewd nymph.
