First, Jen wanted to be sure she would be safe, should she decide she ever wanted to have sex with any creature without protection, as well as for a few other things. Looking back into the mirror, she voiced the change.
"Transform or Dare?"
"Both."
"For your transformation, whenever you have sex as a man, woman, both, or any combination, you will not be able to get anyone or anything else pregnant, nor will you be able to be impregnated by anyone or anything. This will last until another Transform or Dare cancels it with the words 'You can now have children of your own blood.' Also, any transformations that you have will be accepted as normal by everyone else. You can be partly or fully nude, and only you and your alternate personalities will notice, while everyone else thinks nothing of it. No one but you and your alternate personalities will notice any changes to your body, not even Kyle. Finally, you can change all parts of your body at will, though Kyle's curse still affects you. For your dare, you will never give the Transform or Dare curse to anyone but yourself and the different personalities of yourself that you think up for the purpose of the curse."
As Jen finished, a slight tingling washed over her, but nothing major. Deciding to test her new powers, she stripped her remaining clothes off and stuffed them in the bag. As she walked out the door, she paused. Despite her knowing most of the material, Jen still didn't want to get into trouble for not doing her homework. So, she willed it to appear completed in front of her, written out in her handwriting, and to her usual satisfaction.
Suitably prepared, she hurried out the door of the restroom and back down the hall to rejoin her class, getting quite the thrill as the cool air brushed her nude skin, tits bouncing and ass jiggling as she trotted back to her class.
