Erin flushed the toilet then went upstairs to find Harry and he found Harry quickly in front of his laptop watching some videos. Erin said "Um... Harry can you help me with something?"
Harry didn't glance and then said "What do you need?" although he could've sworn Erin's voice was a little different.
Erin said "So I was down in the lab a-"
Harry paused the video and immediately said "Erin what did you do?!?"
Erin said "There was this big machine I went into and... it turned me into a boy."
Harry looked at Erin closer and noticed the differences including a rather small bulge where his crotch was and then said "I wont tell just show me what you did." Erin nodded and they both went into the machine. The machine greeted them and then option windows popped up for both of them.
Erin said "So I pressed this button and it turned me into a boy." Erin pointed to the male button in a subsection."
Harry said "Well all you have to do is press this button." he pointed to the female button but accidentally hit it. The machine warmed up and then made a change, but what exactly happened?
