A woman's purpose

The time has come. You ended up in the hospital with contractions. The labor didn't last long. Your body seemed to be made for childbirth. Everything went smoothly. Your daddy-husband was with you throughout the birth and watched the birth of your first and his next child. You gave birth to a beautiful, healthy, strong little boy, just like Daddy. The feeling of creating a new life that was growing inside you was amazing. Even better was the feeling of nursing as your baby sucked milk from your swollen, food-filled breast. You no longer remembered that you were a man. Now you were fully a woman, fulfilling a woman's purpose. To bear children.
Time passed. It was difficult at first, but your feminine instincts guided you through the hardships of motherhood. Your daddy was proud and pleased with his offspring. He helped you a lot with your duties, seeing in your son the hope that he would grow up to be a strong boy. You didn't even notice how a month had passed since giving birth. Your body regenerated superhumanly fast. Your breasts remained larger due to the milk inside them, your hips seemed wider, but that only added to your beauty. It seemed that your body was ready for action again. That day, when you managed to put your son to bed, you heard a voice. A voice you hadn't heard in a very long time. That same voice announced to you that you were a girl. The same voice told you that you would be a girl permanently if, for a period of 48 hours, someone got you pregnant.

"Hello hello, we haven't heard from each other in a long time. You gave birth to a beautiful boy. You must be very proud of it, huh?"

"You..." your voice trembled "Why did you come back?"

"To continue our game. You lost the first round, though I think you did it on purpose. You enjoy the life of a woman, don't you? It's so much better than your old self, isn't it? Having that body, feeling incredible pleasure, bringing children into the world."

You remained silent, there was no point in denying it. He was right. You had forgotten your old life. This, was your new reality. You are a woman.

The voice continued:
"This raises the question of how much you actually care about remaining a woman and how much you are willing to do to prevent me from restoring you to your original state."

You felt the terror. You didn't want to go back, you have a husband, a child, a life a thousand times better than you had.

"I'll do... I'll do anything"

"Good answer, that's what I expected. Let me give you the rules for the next round of our game. You have three months from today to get pregnant. Your body, beautiful as ever, is no longer extremely fertile as it was in the first round of our game. Your fertility is like that of any healthy woman. If you really want to remain a woman, you need to get pregnant. Such... rule change."

"But... I already have a child. I can't handle raising him and trying hard for another one at the same time."

"Relax, the game will be fair. There will be a babysitter knocking on your door in half an hour. Your child won't be able to get better care than her. The girl is taking a gap year from school, so she will be available 24/7. Prepare her room and she will take care of your child right away so you can start playing our game. "

"I... well... but I don't want to play this game anymore. I want to live in peace."

"And you will. If you're good, this round will be the last. Have fun making the baby." The voice disappeared and you were left alone.

You have prepared a room for a baby sitter. You opened the door when she appeared in your doorway. She was beautiful, with red hair, freckles, a sexy body with a large bottom, full, large breasts. She was dressed comfortably, in leggings and a light blouse. Apparently not revealing, but her body would still make men happy.

"Hello, ma'am. I'm Katie. I'll be the babysitter for your baby."

"Hey, Katie. Come on in."

You invited her inside and led her to her room. After you showed her the baby and explained everything to her, the girl immediately got to work. It was time to start worrying about the task you had been given. To get pregnant once again. Only... from what... or rather, who would you start with?
