Mr. Croston had said "Magic was not real, and I will prove it to you" as he held the coin then said "I wish that I would be able to hold the attention of the boys in may class."
He had meant for them to pay attention to what he was teaching at the time but the coin took the meaning another way.
Mr. Croston had just finished saying his wish when he felt a tingle go through his body as he dropped the coin on the desk as he started to transform. It did not take long before he had been turned into a gorgeous buxom blond woman with a pair of DD cup breasts. His or rather her hands went to her breasts and squeezed them, not believing at first what had happened. As she was examining her body her clothing changed into a tight dress that was vary short and was revealing a large portion of her breast. She stood up loosing her balance for a moment on her high stiletto heals, as she looked down all she could see was her huge breasts as they seemed to get bigger every time she took a breath "OH MY" she said as she turned.
