she is industrious

"What have you done to me!"

A logical reaction. You expected this.

"I have combined you with the essence of an animal." You casually explain to her.

"What ... why would you do that?"

You paced around the table, explaining your goals to her.

"The world has very few creatures in it, my dear. Every day, many species go extinct, but none are added to it. This is my way or repairing that error. With you, I have given nature a new species. One that is based on the human, the most successful species to date, and I have improved on it."

Your victim was shocked.

"You ... improved me?"

"Yes! With this new body you have enhances speed, greater stamina, improved hearing. You are better then you have ever been before."

You had thought she would rejoice, but instead she started crying.

"I did not want this, I never asked it. Let me go." She pleaded.

"I am sorry, my dear. But I am afraid society is not ready to accept you yet."

"Why not?"

"There are simply too few of you at this point."

"Then change me back."

You shook your head. "The transformation is irreversible. You will be stuck in this form."

The girl realized you were speaking the truth. Her strength visibly left her.

"So ... am I going to remain strapped to this table then?"

"No, you can walk around if you like. As long as you don't leave this room, you should be safe."

With a wave of your hands, the straps unfastened themselves. The girl quickly buzzed off the table and flew to the other side of the room. You decided to leave her alone for a while. It would be good for her to get adjusted to her new body.

Like you warned her, she did not attempt to leave the room. She was probably too ashamed. Ashamed of her half bee body, as well as ashamed of her nakedness. Even now, she tried to make herself a skirt and bra out of some cloth she had found lying around.

You were happy, your experiment was a huge success. However now, you had a bee-girl to deal with.
