"I like her, but I don't want to be Scarlett Johansson!" You scream at the genie.
"Change me back to a guy right now!"
"Are you sure about this? I said I would only make small changes."
"Do it right now you stupid genie!"
The genie's face goes dark. "Very well but you asked for this."
The genie snaps his fingers and disappears.
You feel a change but you still look like her and have a pair a breast. It looks like the genie didn't do anything, until you notice a bulge in your pants. Guess you aren't gonna be wearing any tight pants or mini skirts from now on because...
Your now a perfect copy of Scarlett Johansson in every way expect you also have a dick.
