Chapter One (The Birthday)
Okay, so here's how it works in my family – anyone can have anyone. That's the basic rule, there are others such as all sex must be consensual and there can be absolutely no incestuous pregnancies (the necessary precautions have been taken). It started with two sets of siblings – Ian and India Ash, a pair of Native American siblings with dark-ish skin and black hair, and Vincent and Adrienne More, a pair of blonde haired blue eyed all American siblings.
Ian Married Adrienne and they had twin daughters Vienna (me) with blonde hair, blue eyes and pale skin and Nerinda with dark skin and dark hair.
Vincent married India and they had twin daughters Alice (taking after her father) and Mischa (taking after her mother)
We all share the same surname of Ashmore as we didn't think it fair to use just one of the family names, so it was combined.
We've all lived together since I can remember, and our parents have been 'mixing' with each other since before that. We offspring were all born in the same month (September) and have always done everything together. Since we have been able to comprehend sex us girls have been exploring each other, our mothers taught us more when we got a little older and our fathers made us women when we were ready.
Now that you know all about my family let me tell you a little more about me. As I said my name is Vienna and I have blonde hair, blue eyes and pale skin. I am fairly tall at 5' 8" and am very slim (size 0), my breasts are small but perky which I like as I would hate for them to be in the way. (My sister and cousins have pretty much the same body type as me but Nerinda and Mischa are a little curvier). I love to wear mini skirts and little tank tops to show off my slim frame.
I recently turned 18 which is where this story will begin...
The day of mine and Nerinda's eighteenth birthday our mom came in to talk to us, she said that today was the day that daddy wanted to make us women. We were so excited I had wanted this ever since I was 15 but was told that I had to wait until my 18th to make sure I wanted it. I did, I wanted it so bad that I almost peed my pants when mom said that today was the day. I knew that I would be first because I am three minutes older than Nerinda, I could see the jealousy in her eyes and understood it completely. She wouldn't get fucked until tonight but I got to have it now.
I walked into my parents' room, where my dad was sat on the bed. Mom closed the door behind me leaving my father and me alone. Daddy patted the bed beside him and gestured me to sit with him. I walked over, my legs shaking, and sat on the bed next to him.
'Honey, are you sure you want to do this?' My dad asked politely.
'Yes.' I replied with a shaky quiet voice. I coughed and spoke again. 'Yes daddy I really want this. You know that.'
