Iabet looks at you with a disinterested stare. You aren't sure if she is satisfied or not, so you decide to just ask.
But before the words are spoken, she interrupts.
"Mortal, I am bothered. Your virility is not as strong as I had thought, and your seed has failed to take root inside of me. But you have also proven yourself to be a loyal servant."
"So what does that mean?" You feel nervous.
"You are not fit to be the one who will give me a child. But if I am to find the one I seek, I need a handmaiden to serve me. You will be adequate for such a purpose."
You gulp. "But if handmaidens are female, are you going to..."
Iabet smiles. "I will not make you a woman. At least, not a true one. My servants are all half-man and half-woman." With that she reaches out, and you feel her take hold of your cock. A flash of light, and she is holding what looks like two glass marbles in little leather sacks and a thick wooden rod with a finely carved tip. Looking down, you see that your penis and testicles are gone and all that's left is bare skin.
"What did you-" Your voice is suddenly much higher, but still sounds like your old one. Iabet laughs.
"Let us finish your transformation." A wave of her hand, and your skin turns the same hue of rich brown as hers. Your hair is now short and black, and you have a white dress-like garment wrapped around your body, which is now skinner and curvier.
"Mistress", you cry out. "Please, let me feel pleasure again."
Iabet smiles and reaches out. A flash of light, and you suddenly find that a slit has opened where your cock used to be.
"Now you have the genitals of a woman, servant. But you will not use them without my permission. Now, let us find the one who will impregnate me."
