Turn him into “the other woman”

You flick your wand in the direction of the muscular man. “Bibbidity, bobbity, boo...” you say. A puff of blue smoke engulfs the man. The smoke swirls around his form until you cannot see him.

The smoke clears revealing a woman with magma-red hair and scarlet red dress. Her body built for sin. She is sitting seductively on the bench looking at her red iPhone. It rings with a classic Taylor Swift song.

“Hey there, I was just thinking about you,” she says coyly. “Did you manage to ditch the Ball and Chain today?”

There is a pause where she closes her eyes and shakes her head.

“Well you’ll be missing out,” she says, “I’m at the mall right now and was going to buy a sexy costume and lingerie if you got here, but... that’s what I thought. See you soon!”

You turn your attention away from the redhead and examine your reflection in the nearby glass door. You are now completely a woman. Your face is soft and feminine, no evidence of you ever have been a man. Long blonde hair falls in front of your eyes.

You look at yourself entirely and realize you are a now a grown woman wearing men’s clothes. You could continue home and hope that this isn’t permanent, though you could go back to the magic shop and return the wand. Maybe that would revert your changes?

You could also accept your fate, magic up and outfit and continue to try to be a Fairy Godmother. The choice is yours, there are plenty of other options as well, such as assisting this new woman with her affair.
