"Screw it! I've come this far, why not become a complete woman?" You say.
You are briefly troubled by the fact that you would so quickly give up your own manhood just for a chance to have sex with yourself. But that feeling quickly passes because you have a chance to have sex with yourself!
The two of you do some science type things in your workshop that culminate in the construction of a machine that can turn men into women. No big deal.
Anyways, it's finally time, the time you've all been waiting for, the entire reason you came to this site and clicked on those series of links and why you did all that reading and why I wasted my Friday afternoon to write this nonsense!
IT'S TIME TO TRANSFORM INTO A WOMAN AND THEN HAVE SEX WITH YOUR IDENTICAL CLONE!
(wtf am I doing with my life?)
You removes your clothes and gingerly step into the machine that suspiciously resembles an 18th century torture device. (You had all these spikes lying around, might as well use them)
"You know, I think I might be having second thoughts..." You say.
"Well, too bad." Your clone says as he flips the switch.
All of your body hair spontaneously falls off. You were expecting the spontaneous-hair-fall-off field to have more fan-fair and what not.
Suddenly a pair of suction cups descend from the ceiling and attach themselves to your chest. You try to forget the fact that they were made out of toilet plungers as they suck your pectorals into nicely sized breasts.
A horrifying iron death mask comes down and smothers your face as it restructures his skull and skin into a more feminine shape.
Stacy, a local hair stylist that does home visits, walks over to the machine and makes your clone's hair look pretty. She seems to be kind of justifiably weirded out by the two of you but your clone tipped her a fifty before she left.
A series of pneumatic belts snake out from under the rig and wrap around your body, they squeeze and crush you into a womanly shape. This is actually extremely painful.
A steel box comes up from between your legs and snaps around your genitals. You say one last goodbye. There are some cutting noises and much screaming.
Then an artificially grown female reproductive system complete with functional synthetic ovaries is slided into the steel box which applies all the necessary fittings. You feel strangely full and much more feminine.
With a resounding beep, the machine snaps open and ejects you. The machine then proceeds to catch on fire. After dealing with that, you take a look at yourself. You now resemble what you would have looked like if you were born as a girl. Of course you are stunningly beautiful, you are you after all. You actually kinda looks like a younger version of your mom, or your sister if you happen to have one of those.
"It worked!" You cry.
"You're a girl!" Your clone says.
"...These seem nice..." You say as you grope your own breasts for a while. They are soft and squishy, almost hypnotic.
You slip an exploratory hand between your legs and touch your clitoris. Electricity bolts through your body. "And this seems really nice!"
Your clone watches sheepishly as you explores your new body.
You get a few naughty ideas as you give him a mischievous look. "Hey... why should I have all the fun?" You say.
"Uh..." Your clone stutters as he tries to answer your rhetorical question.
"Come here." Your clone pulls you into your bedroom.
