Galactic Whores: Brother and Sister Part 1 (Incest, transformation)

If there is enough interest I'll post the second part of this story, which will include plenty of alien species that do some incredibly sexy things. No worries, nothing like blood, gore, vomit, scat, or anything gross will be in any of the chapters. Let me know what you think of it!

***************************************************************

I was 18 when it all started. I was a skinny kid, growing up on a farm with my twin sister Hailey. My name is Alex, and this is the story of how I became famous accross the galaxy!

I groaned as the alarm clock went off at five like it did every morning. I reached blindly and slapped the snooze button. I pulled the covers back over and tried to go back to sleep. As usual I was lying on top of the blanket because it was so warm, even at night. Just as I began to drift off, I felt an arm fall around my shoulders and a soft voice say:

"C'mon Alex, we have chores to do."

I groaned, wanting to avoid the inevitable. I cracked one eye open. Hailey was wearing her usual summer nightclothes: a thin, white tank top and purple panties. I lay there for a moment admiring my sister's beauty. Curly, long black hair framed a soft, sweet, slightly freckled face. Her full red lips smiled and showed off her perfect white teeth, and made cute dimples appear on her cheeks. She was average height, about five foot six, but she made five foot six look really good.

Her breasts were a nice C cup size, nice and full. I could see the outline of her nipples through her shirt, and they were just the perfect size in my opinion, not too big, not too small.

"C'mon, sleepy head. Let's get a move on!"

She turned and hopped out of bed her back to me for just an instant. Even her ass was awesome, just the right size. Toned and firm, but not skinny. Every morning I got the same good look at her and it still didn't get old.

I gave one final, complaining groan and rolled out of bed.

"We stayed up to long last night."

She laughed. "Oh, you have to stay up at least past midnight on your 18th birthday. Besides, didn't you have a good time."

I just had to grin back. Sis's exuberant disposition was always infectious.

"Yeah, it was."

She gabbed her work clothes and hurried off to change in the bathroom and left me to change in our room. Yes, my twin sister and I share a room and sleep in the same bed. We did it when we were little, living out on a farm two hours from the nearest city, being homeschooled and basically having little contact with the outside world. We only had mom and each other, and we were closer than any siblings in history. We did and shared everything together. We had no secrets. I loved sis with all my heart, and she loved me.

I grabbed my jeans and looked in the mirror. I was just a little shorter than sis, about five foot four, wh
