Outfit adjustment.

Emma, having strong telepathic powers herself, immediately worked out what was going on. She knew the professor must be trying to teach them a lesson. "Oh well," She said to herself (or to Kitty) "Better make the most of it."
Emma looked at Kitty's outfit in the mirror. A full body spandex suit in blue and yellow with a zipper running down the front. "This won't do." She started going through Kitty's underwear drawer, discarding anything that covered too much ass. "No! None of this will do." Emma exclaimed as she walked across the room. She found a pair of scissors in the bedside cabinet. She began to unzip the outfit but then she had a thought. She concentrated hard, and used Kitty's powers to step through the costume. She began cutting the costume until it was nothing more than a pair of spandex booty shorts and a tube top with a zipper. She put the outfit on and admired her handy work. "One more thing." She thought and pulled the zipper down halfway to show a little more cleavage. "Not much," she said and she felt Kitty's breasts, "but they'll do."
