Clara thought of something that men always seemed to like on women. Hourglass figures.
She searched through the options and applied it once she had found it. She made sure to not give men any breasts or have a noticeable change in butt size.
Clara looked over towards Jeff who started to feel an odd sensation in his abdomen, "Clara, what did you do?"
Jeff grunted at his waist decreased in size, his sides became more curved and his belly became more rounded and inverse.
"Nothing much, just made you feminine in a way", Clara smirked in amusement and slight arousal.
As his changes completed, Jeff realised just what Clara had done, "You gave me an hourglass figure?"
"Yep, you now look you are on your way to being a trap", Clara cooed, "It's kind of adorable really."
Jeff sighed and switched with Clara, 'In what way can I get back at her?', he thought.
