Suddenly, the line-up of panties on the teacher's desk weren't so appealing. But the boys still seated were. And in no time at all, Jon (or Jen, as she started to think of herself as) began to imagine some new forms for them. Boys with large, bulging, rippling muscles and huge cocks. And the more she thought about cocks, the hungrier she became for them. It was a strange feeling indeed, but she liked it.
And as she stood there with all of her sisters at the head of the room, all the boys in the class changed simultaneously into their new sexy forms. Jen smiled, imagining what she could do with one of those boys ... or even all of them.
