Before Ty made his next move, he willed Dustin to be mature again. What he was about to do would be even funnier if Dustin was a mature male.
"Why are you wearing boy's clothes?" Ty asked his foster brother. "Have you forgotten you're a girl?"
Dustin looked down, puzzled. "Thanks for reminding me" he said, and went upstairs to get changed.
Ty used his power to replace Dustin's male clothing with a selection of the finest slut-wear. Dustin came down with a low cut shirt showing off his nonexistent breasts, and an exposed strip of midriff with a pierced navel. The shirt read "Boy Toy." Sequins on the rump of his jeans spelled out "USDA Prime."
Ty liked his handiwork, and added a tattoo on Dustin's arm with an eye, a heart and a rooster.
"You're looking particularly slutty today, sis." said Ty. "But then, you are the biggest slut at Harrison High."
"Thank you." blushed Dustin.
Ty pondered whether it would be funnier to have everyone recognize Dustin as the boy he really was while he thought of himself as a slutty girl, or to make everyone (except Ty himself, of course) see Dustin as the girl he thought he was. The vestigial twinges of Ty's conscience had almost vanished.
