Jeff soon arrived at school in his new body. While he was used to being a guy, he found that his new form came with an extra spring in his step that made it a lot easier to walk. As he was heading towards his homeroom, he ran into a familiar face. His girlfriend Alexandra was heading to her own class, when she spotted him. Jeff had been best friends with the red-headed beauty since they both started kindergarten the same year.
"Jeff? Is that you?" The normally outgoing girl seemed almost speechless.
Jeff waved. "Hi Alex."
Alex looked him over. "Since when were you able to change?"
"Well, my parents helped me this morning."
Alex came closer, examining his body. "Huh, I didn't know you could look this good."
"It's a bit strange being like this." Jeff replied, blushing slightly.
Alex wrapped her arm around his shoulder. "I'll bet. But you look great."
Jeff blushed red as beetroot. "Thanks."
The bell rang and they walked together towards their Changing Class.
When they arrived, they found that they were the last two students to enter. Ms. Juliet Jones, the 50 year old history teacher, was preparing a overhead projector and was about to start class when she saw them. "Ah, Alexandra. Welcome. I assume this is Jeffrey?"
"Uh, yeah." Jeff replied as he sat down.
"Alright class. For our first lesson we are going to learn about how and why humans can change our gender. We'll cover the biology behind the changes and go over the process in detail..."
The class went on, covering the basics of human anatomy, both male and female. Some of the facts he already knew in health class, but there were other things that Jeff hadn't known. Like how the ability to change sex was due to a prolific genetic anomaly that had appeared 2 Million years ago. Since then, humans had slowly spread out across the globe, taking on the abilities of other species they encountered. Eventually, humans developed the ability to consciously change into either sex and back.
As the class came to a close, Ms. Jones spoke again. "Now that we've covered the basics, let's talk about how you can actually change between genders."
She wrote on the board, "What you need to know to change". She then turned towards the class. "Now, you need to focus your mind on what gender you want to be and you also have to relax your body, otherwise the change will take a long time or be a bit painful. Here's an example."
Ms. Jones quietened down as she began to transform into a man. Her breasts disappeared under her jumper and her body got more muscular. Her voice became deeper as she spoke again. "Seeing as this is the first class, there's no homework this time around. But I's recommend reading the first two chapters of your textbook to brush up on things. Class dismissed."
