You barely made made it to the bathroom before the changes began. You picked the girls thinking of what was going to happen. Seeing a Caution! Wet Floor! sign nearby, you use it to block the bathroom so you can be alone.
By the time you look at the mirror you can see your arms growing longer and you getting taller, stopping at 5'8". You arms and legs became considerably thinner, and you hands were very dainty, with your fingernails turning a bright pink. Long, straight, blond hair came down past your shoulders to a thinning waist and expanding behind.
You almost lost balance as your feet shrank down, but quickly a sudden feeling of muscular strength engrossed you, despite no visible muscles.You also felt like you knew everything, but you seemed to prefer hiding it. You looked like a bimbo, why not play the part? You felt your face soften, your lips became fuller and red lipstick appeared, along with other makeup.

Finally, there was clothes. Your sneakers melted into 3" heels showing that your toes were also painted a bright pink. Your jeans receded and ended in a tight black skirt, or so you thought. As you shirt changed, the skirt and shirt combined to form a really tight dress. Your breast hurt from not only weight, but from the tightness of the new dress.
After a few seconds of looking at yourself in the mirror, the pain seems to recede. After all, you wear this all the time, and you've had these breasts for years. Wait, no thats not right. Just an hour ago, you were male. The changes must be affecting your mind. You realize that although you selected to retain your memories, seeing this new form makes you think this is natural. You know you need to work on separating your thoughts. You then look at the clock and see that math is almost over, and you should be getting back to class.
"Get yourself together Ashley," you say, getting ready to go all out bimbo. Wait? Ashley? That wasn't right. You were Aaron.
"I guess not anymore," you say, giggling to yourself. This role as a girl was easy, especially since you can act like a bimbo.
Suddenly, a shadow starts coming around the corner. Someone must have heard you giggling in here. You turn and see...
