Wandering around the machine, it seems scientists were testing a new kind of beam.
The functioning is too complicated for you to understand and by the way it's not working.
You enter the tube but the girl warns you. "There is no way this can do something to us calm down...".
That's exactly the moment where she accidentally slip and press the button. A thin red laser hits you and disappear instantly.
Nothing happened. You and the girl wonder what was the meaning of all of this ?
"Pfff, another useless nerd junk !" she says.
'Let's get outta here, I don't wanna waste my time any longer." and then you walk out. Actually it wasn't really a scary lab.
At the exit you turn your head to the girl and she does the same. You blush both. How cute !
"Ok, now it's time to say... goodbye ?". That's awkward. "Yes hum, 'bye..." You turn around and go the opposite way. On the way to home you ask yourself if after all it was a bad experience. You get home and don't tell anyone about this. One more night and it's time to come back to school.
You don't meet the girl today, she must be trying to avoid you for some reason, maybe she doesn't want to talk again about the lab. You go to the toilets and wash your hands but mechanically watching the water falling on your fingers you feel something is wrong. Are your fingers... longer and thiner ? "Absurd" you think. You try to forget this but in class another thing happens. It seems you have pushed a little too much on the fast food this month, it's almost like you had small bead of fat on your chest, and anyone can see it. You fear that the others could say "you're fat shithead" or something like that.
But nobody seems to notice it.
At home this evening you don't notice either that your shoes are loose and your feets seem to have shrunk. But things are getting weirder when in the bed you see that your dick too have shrunk ! From a good 6" it's not even 4" now... You get up and see that you are in fact entirely shrinking, you lost almost 3 inches ! Upset by those changes you can't sleep and the morning ask your mom to stay at home. "There is no reason for you to not going to school." and that's how you're back in class.
You rush into the restroom and look at your face. Ah, this time you're sure it's more feminine ! Your hairs now fall on your shoulders, and panicking you realize you're becoming a woman ! Obviously now it gets faster, and even if before your dick was at least there, you don't feel it anymore. With your new smooth and long fingers you take off your underwear, and see what your dick has become. Really ? You can't believe it. You have a pussy ! "No way !" you yell with a high-pitched voice that you don't recognize. "Oh god now I have a girl voice too !". You fall on the ground, extending your long feminine legs and all that you can do is watch in horror the two little A breasts on your chest expanding and growing pleasurly to a good C-cup, your nipples also growing to almost an inch. You still can't believe it, and start to lose consciousness and...
You wake up.
You are still in the toilets, and you just remember what happened to you. You quickly run into the girl's room and lock yourself in. You look down, intrigued by your new body. You must be something like 17 years old, and you face the mirror. Amazing, and strange. You contemplate your beautiful eyes and small nose, your nice lips, your plentiful dark hair... And below, a pair of round C-cup breasts, blocking the view of your lower body. You enter a cabin and close it, and examine your thin waist and large hips, to finally tickle your newfound vagina with long woman fingers, sending you a short wave of pleasure. You stand up, hands on your hips, it seems you lost some inches, but now you have tall woman legs. "This can't be real" you whisper with a womanly voice. "But what can I do now ?"
