You wake up, the morning light filtering into your eyes. You slam your hand down upon the alarm clock next to you. Weirdly, your arm feels a bit more weak.
You begun to feel something strange in your body. You're slightly smaller, and your skin is softer and smoother. Then you can feel more strangeness as you awaken, there's breasts on your chest now. And you can feel emptiness where your dick used to be, especially with the front of your underwear snug agaisnt the spot your oenis used to be, and the closed legs where you should have balls, it's pretty clear your crotch is now flat and dickless.
You sit up and look in the mirror. It's clear, you're completely female. You can see and feel it. Your not sure if it's wrong to think but you're a pretty cute girl, with a nice fit but slim body, and a nice face.
You realize that if you're in a different world, it's more then just you that's changed. Quickly you pull out your phone and look up the word gender.
The word gender doesn't seem to exist in this world.
Neither do words like male, penis or man.
Upon further inspection something is pretty clear: you've woken up in a reality where everyone is female.
