Jon turned around, thinking there wasn't enough room on the desk for a fourth person, to see Jennifer stand up from her own desk. She was already wearing a skirt, but it shrank from her knees to mid-thigh right as she passed Jon. When Jon looked back at the desk, it had gotten wider, making just enough room for Jennifer to lean over and expose her white underwear.
Lisa kept repeating this process until all of the girls in the class were bent over, wearing short skirts, and exposing themselves for the rest of the class. Towards the end, the room itself had gotten wider.
"Still not enough information!" Lisa cried.
