Sean felt himself growing, so he quickly took off his little boy clothes. Unfortunately, he wasn't simply aging. He was becoming
an exact copy of his sister, possibly a few years younger. It was a weird feeling as his testicles folded up into his body, his penis shrank into a mere nub, and breasts filled out on his chest. Sean tried to pay little attention to his newly changing body. Some guys might be quite attracted to this naked female flesh, but Sean felt he was looking at his sister naked, which was not something he found sexually exciting because of whose flesh it was.
Once Sean's anatomy had settled down, she had a chance to try her theory. Was it a matter of using the right fabrics? She tried touching the medallion to the young boy shirt that had triggered the first change. Nothing happened. It was then that she realized, it must be a 12 hour thing, since it was now about the same time as it had been 12 hours ago when Sean became his younger self. Okay, that was settled. She was stuck as a girl for the next 12 hours. So... what to do?
Well, first, she had to do her one task for the weekend: taking clothes to Goodwill. But, thinking about the potential of the medallion, she held back a few items, squirreling them away in her room. Then, before she could take the clothes out to her sister's car, she needed to get dressed. No need to get dressed fancy or anything, so she just put on a T-shirt and jeans just like what Sean would've worn today if she hadn't become a girl (with the exception that Sean would normally have worn underwear). Sean's clothes didn't fit all that well, but that it wasn't like Sean was about to start wearing girl's clothes or anything, even if they would fit better.
Then, after loading up the car, she realized that she better not get pulled over since Sean's driver's license showed a picture of the guy he used to be. That could be a problem. But then she realized, Sean's sister had left her purse here at home since she wouldn't need it while camping. Sean grabbed the purse to take it with her and then drove to the Goodwill center, dropping off the clothes without any incident.
Now what?
What else was there to do? Sean drove to the mall.
