The ritual

You are dragged onto some kind of altar at night.

The temple itself is located deep inside the jungle of the island, impossible to find if you don't know the way.

The area itself is under the night sky, no roof is obstructing the view to the moon. Around you there are columns, pillars with the image of Venus carved onto them, on top of which a semi-circular shelf holds a very big crystal.

You are tied onto the altar and the gathering of girls stands around you.

"Children of Venus!" Today we shall greet our new sister! A daughter of Venus! The crowd cheers.

"May the Venus bless you, I grant a new name upon thee..." She pauses dramatically.

"... Elaine!" The crowd cheers again.

The rest of the process was silent.

They waited until the moonlight hit the crystal and the whole show started then.

The rays were warm and your body quickly warmed up, sweating profoundly.
With each drop you were sweating away the rest of your masculinity.

You were shrinking down even more, to a petite, female size and your chest began swelling up with a rounded set of small breasts.

masculinity -100%

After an hour of laying in this heat, your chest has grown to a quite sizeable set of boobs and your dick was now almost non-existant.

The tip has started morphing into a clitoris and a small opening was created, slowly opening up a wet slit onto the world.

The ropes you were tied in were now pretty much loose, but the process was so tiring that you could only lay down and moan.

The last phase was quite pleasurable, your soft moans were now completely girly and as you wiped the sweat from your brow, you felt a long strand of your new hair that grew over the last couple hours.

The ritual continued until the sunrise, but you can't remember much after that, as you were hallucinating pretty hard for the last hour.

Your most recent memories didn't quite add up and you weren't really sure what was real and what was a dream...
