You think about what word you should change in the sentence displayed on your phone. "This young woman is having her modest bust ogled by two men."
An idea comes to mind, something weirder and more original maybe. You decide to change the word "woman" into "man", wondering if this would actually give Emma a real sex change. You tap to confirm the change when the app suddenly displays an exclamation mark icon with a message box. It reads "Warning - changing the selected word must have consequences on some of the other words in the sentence!" Interesting, you think and notice that the words "her" "modest" and "bust" became greyed out! The app took a few seconds to process and then, with a chime, displayed the new edited sentence "This young man is having his elegant necktie ogled by two men". The app asked to tap again to confirm and you do just that, before turning your eyes back to Emma's desk curious to see if anything happens.
After a few seconds, you go wide eyed as Emma completely morphs in front of your eyes! First of all, Emma's clothes simply vanish into nothing, leaving her nude (and seeing this gives you a bit of a boner!) Next, her long dark hair quickly shortens into a buzzcut and lightens to a regular brown color. Her makeup and finger nail polish disappear and her eyes change color from sky blue to a common brown. Next she grows a few inches taller, her C cup breasts flatten completely and she loses all of her feminine curves. Her hands and feet grow a bit bigger and are no longer feminine. Next she gains some more muscle mass and a considerable amount of body fat, giving her the physique of a slightly fat guy with a beer belly. Then she quickly grows a 5 inch dick and a pair of balls while her whole body gets covered in light body hair. Her face is the last to change - it quickly morphs into the face of some random, regular looking guy who is a completely different person who looked nothing like Emma. To finalize the transformation, new clothes appear out of nowhere to dress HIM up: sneakers, plain blue jeans and a tidy, white button up shirt. A nice looking blue tie (an homage to Emma's deep cleavage top) completed her new and improved look. And there you go, Emma is now a man!
After the changes were over, you see that Emma (if that's still even his name) resumed working the front desk. The two guys who were previously ogling Emma's boobs were now simply asking her where she -sorry, where HE- bought his tie... They all acted as if nothing had happened, as if they aren't at all aware of the transformation that happened with Emma.
Curious, you then decide to...
