Mary didn't understand what was happening. She had been teaching her beginners class when on of the girls had asked her "What's happening to your hair Mrs Jones?:"
Mary got a shock when she saw her reflection in the mirrored wall. She was going grey! She couldn't help but give a shriek of dismay before regaining her composure. She told the girls what they needed to practice and excused herself to go to the toilets.
That had been 20 minutes ago. She needed to get back to the class. She should not be leaving the girls unatttended - but there was no way she could go back into her class. Not with the changes she was somehow experiencing. After verifying that her hair had indeed gone grey in the wash basin mirror, she had stood there in stunned silence. She had retreated to a cubical and hidden there after a girl had called out for her Mom at the door. Now she was too scared to come out and check her reflection once more.
Her leotard was doing nothing to hide what was happening to her body. Now it was stretched very tight. Her boobs had gone but her chest had expanded. The leotard was now bulging in her groin where she had apparently grown a penis and testicles. To make matters worse the changes she was experiencing had made her excited and she had a raging erection. It just would not go down!
Now her hands had changed as well and she found she had large muscles in her arms. Feeling her face she could feel she had whiskers and an Adam's apple. There was no doubt that she had somehow turned into a man! She tested her voice and a deep sound came out.
She realised she could not stay in here forever. The girls would be running riot in the classroom by now. However there was no way she could re-eneter that room looking like she currently did. Hopefully Paul or Gary (Mr Dawson) would hear the noise, investigate and supervise the girls until their mother's came to collect them. Meanwhile she would hide in the cubicle until everyone went home. Only then would she venture out once more.
