Here she was lording over you. You never thought it would go this far, but now you were in over your head. It had all started as a prank of sorts. You had found a book in a dusty old thrift shop that claimed to contain magical spells. You bought it, thinking it would be good for a laugh if nothing else. What you didnt know was that the book truly was magical.

Later that week, you were hanging out with a friend when you remembered you had the book. You pulled it out and began to skim through the list of spells before finding a really crazy one. It claimed to be a transformation spell that could change somebody in any way of your choosing. Barely containing laughter, you began the incantation while flourishing your hand for dramatic effect. It was around that time that you realized you couldn’t stop. You tried to close your mouth, but it kept on reciting the incantation. The book had felt your intent and was determined to see the spell through.

Before your very eyes, you watched as your friend's features melted and reshaped themselves into beautiful, feminine features. Two mounds began to slowly fill like water balloons on his chest. A third, larger mound began to fill at a similar rate right where his belly was. You would have gasped if the book had let you. Your friend's clothes exploded off their body, revealing a busty pregnant woman still growing with each passing second. You continue to chant as the changes take hold and slow to a stop.

Finally, the book releases you. The woman before you no longer resembles your friend at all, and she clearly isn’t thrilled about that. You had intended to pretend to turn your friend into a pregnant woman as a joke, but the book wasn’t joking. Without a word, your friend walks over to you and pushes you down onto the bed. She climbs up over you, her newfound mass making it easy to overpower you. You weren’t sure what she had in mind, but whatever it was, you would be helpless to stop it.
