Ty decided she wanted to take a second to find out how things had changed, if at all. She picked up her phone and looked up 'gender swap world'. The search results were basically the same as you'd find before she made the wish- weird fetish stuff and nothing more. Everyone who had been a boy or man was a girl or woman now, and vice versa, and no one was acting like anything had changed in their lives.
Ty felt weirdly disappointed by that, but not so much because she wanted to cause some kind of societal chaos as because she wanted to see people aware of the switch. Quickly giving up, she wished to have a vision of how her wish had affected some people's bodies. For some reason, she could tell seeing it would arouse her a lot.
In her mind's eye, she saw a frozen world, billions of random people everywhere held in place by his wish, subjected to his will, his inversion of nature. Though most of them were clothed at the time, she saw them all naked to get the full view of their bodies transforming. In perfect unison, she saw every penis recede and every vagina seal up. Every pair of testicles were tugged inside the body, and every pair of ovaries were pushed into a sac. Every flat masculine chest budded into breasts and every pair of breasts shrank into pectorals. Every receding penis took its new place as a clitoris, and every clitoris above a newly-formed scrotum engorged and swelled into a phallus.
Ty felt more acutely aware of the limitlessness of her power having seen that.
