"You just..." you say in your head, even your perception of your own voice feminized. "You turned me female."
"Of course," she says. "Now I am not a slave to unnatural teenage male impulses." She sighs contentedly as she runs her hands over your woman's body. "I have missed womanhood so much," she says, sounding so happy she could cry.
"Am I a girl forever now?" you ask worriedly.
She laughs. "I can change you back if I want, don't worry. But this is my true form. The form I've not been able to have for so many hundreds of years!"
"I think you're really pretty," you admit shyly.
"Thank you, dear," she purrs, her hands experimentally touching her breasts. She breathes heavily with pleasure.
If I wasn't this woman, I'd want to fuck her, you think. But thinking that alerts you to how your sexuality has been transformed- you think of handsome men with big, firm cocks wanting to fuck your pussy and fill you up.
That makes you think of something. "What kind of spirit are you?" you ask. "I never knew much about Chinese mythology."
"I was a servant of Bixia," she explains. "My role was to grant fertility, encourage people to reproduce, protect them from disease and pain in their mating and childbirth. I guess you could call me a sex god."
"Were you good at it?"
"China is the most populous country in the world for a reason, smartass," she says flatly. "But I was sealed in the qipao because humans became prudish- they saw sex as something not to be discussed, its deities as something not to be worshipped so openly."
"And I guess you want to change that?" you reply.
"I'm not just some pervert!" she says defensively. "I don't simply want humans to fuck. I want them to reproduce! There are 7.6 billion people on the planet- I want there to be so many more. More for we servants of Bixia to love, more to share their lives, more to advance civilization!"
That actually sounds pretty sweet, you have to admit. "And more sex?"
"Naturally," she laughs.
As she puts the qipao back on and walks out of your room, you wonder where she's going to start...
