As the flash happened, he realized that the wish could be taken two ways one, makes him a girl that is disguised as a sexy version of himself, same with his family that was the one he was hoping for (yeah it was a strange wish) The other keeps him as a male disguised as a sexy girl. he really hoped the stone wouldn't pick that one.
He was able to see again, he felt a distinct space in his pants, and a weight and pressure on his chest. He discovered that he was dressed in the same clothes but he was a little taller and more muscular, his face was slightly softer and made him look very sexy in his opinion, he lifter up his shirt finding medium sized breasts taped down to hide them, which was the cause of the pressure. Pulling down his pants he found that he had a little slit, it was weird seeing it from this angle, he was also wearing a tampon, that was definitely strange, having something stuck into a place he didn't even have a few moments ago.
He was curious how the rest of his family turned out so he went downstairs.
