(Do not add any chapter past this one, I'm working on it.)
"So what do we do ? We have no clue as to why this machine is designed..." you declare.
"That's so cool ! If only this thing could work... what are all those buttons ? Do they really need them ? I would just put a big red button on middle of the panel and it's done... oh they actually did !" the girl asserts.
You enter in the tube while she continues to go into ecstasies in front of this scientific masterpiece. You notice the tube is still intact after all these years, there is no hole or crack on the glass. You are asking yourself if this machine is in fact working from the beginning.
The girl says " Hey, if I press the button it won't do anything ?".
"No let me get out before !" She waits for you to exit, and press the red button.
Nothing happens.
She comes into the tube to see if anything changed. You notice that a switch wasn't flipped near the button, and you turn it on. The door of the tube closed suddenly with a red alarm above it !
"Wait what ? What did you d..." the tube becomes black before she can end her sentence.
The current is back in the wires and you don't know what's happening inside the tube. Let's get into her point of view :
You can't see out of the tube, but inside there's smoke which spreads. Your body feels really warm and weird.
Holy fuck you're now naked ! The smoke must dissolve tissues... What does this machine is going to do ?
The tigling sensation is getting stronger and you lose the sensation of your legs. then it's your crotch, your chest and your arms, and finally your head. You want to call for help... But nobody came.
A electronic voice in a speaker in the tube announces one by one what do the laser from the machine is doing to you. It makes the count : "3...2...1 initialisation of the first phase. General physical characteristics modification."
Your body streches taller, and you feel your legs becoming taller too, as you were 5'6" and you're now gaining inches to reach the final height of 5'10". You gain weight from 130 lbs to 140 lbs. It's so weird to 10 cm higher from the ground !
You don't have the time to inspect yourself more, as the voice comes back : "Second phase : Members adaptation and weight distribution."
Your body tickles as your legs lengthen and your hips widen. Your arms lengthen like your legs, but while your feet don't change that much, and you feel your hands becoming thinner and mature, but your fingers are also longer ! Maybe this transformation is not as horrible as you thought ? "Third phase : Sexual attributes adjustement." Oh. No.
You grow amazed while looking at your chest. Before you were almost B cup, nice but just average for a girl of your age. Your chest gets heavier while your breasts enlarge, they are now C cup, but wait it does not stop here! This goes even further as your breasts grow up to a large D cup !
"That's fucking amazing !"
Sure you're surprised and not even sure if it's real, but for now you like this a lot ! The bizarre sensation moves to your crotch, and you moan when you sense your vagina getting bigger. At the same time, you notice your voice is deeper, just the same as a grown woman. You are still shocked when the voice say "Final phase : Face maturation."
Your hair grow a bit, they now go down to your shoulder on your newly acquired breasts pair. You can not see your face changing, but you feel your lips become fuller, the rest not changing a lot. You have a feeling of relief when the voice declare "Age progression completed. The tube will now open".
Let's go back to the guy's point of view :
Totally panicking while the girl was in the tube, you are worried when the door opens. At first you just see that she is naked, and turn your head and say "How the fuck did you find yourself naked ? What did this thing to you ?" you begin slowly, afraid.
"Hey, don't be embarassed ! I know I'm naked but look at me now !" she responded, with a weird voice.
When you turn in front of her, you can't believe your eyes. The 17 year old girl you just met 1 hour before is now a beautiful 26 years old woman ! You are impressed as you check out his new body, from her long legs to her delicate hair, from her graceful hands to her pretty lips, from her lovely eyes to her HUGE breasts !
"You are..." you can't finish your sentence, stunned by what you see. "Very... I would like to say charming but it's just better than that, you're great !" you end up saying.
"yeah yeah I know... no in fact I'm also amazed ! What do we do now ?" she asks.
"You can't stay... naked like that. Nobody will come here, but please find something to put on..."
"I always have a spare outfit in my bag" While she get changed, you go back to the machine, and break the the computer.
