Does he make the changes?

He’s interrupted

Before he could open the notebook a door nearby opens and a head peers out. Casey instinctively covered himself up in surprise even though the rules had changed. The head looking out was his teacher, Miss Jackson. She spotted Casey and immediately walked over to him. He was distracted by the change in her appearance. For the most part she looked the same, brown hair, light skin, athletic, tall, same clothes. However her red dress stopped around her stomach and split into two strips that fell down her side, leaving her front and backside completely exposed. Her long legs were smooth and athletic. She had a neatly trimmed bush in a triangle and underneath… was a massive cock, around 12 inches, 6 times as long as Casey’s current size. It looked to be circumcised as the head was visible. Underneath were her balls, hairless and equally impressive as her cock. It bounced and swayed with her hips as she made her way over to Casey.

“There you are! Are you finished cleaning yourself up so we can get to the demonstration?”

Casey was stunned and just nodded along even though he didn’t quite understand, still trying to wrap his head around all of the changes he was seeing.

“Great, then let’s go back to the classroom and get started.”

She grabbed his hand and pulled him into the room before he could register what was going on.
