Let me tell you about Kimberly, has shoulder lenght blond hair, and hazel eyes, and is about 5'3" tall, and is about 110 pounds with a 34 c size breast.

 I have wanted to have sex with Kimberly for a long time now.  I was in my room thanking about haveing sex with my sister Kimberly, I was so horney, I got out off my bed, and started walking to my bed room door, I open my bed room door, and started walking down the hall way to my half sisters, bed room, I started openning her bed room door, I started walking to the bed, and started to pull the cover's off of her sleeping body, I moved my body next to her sleeping body.

I moved my hands to the waist bands of her panties, my fingers slipped inside of her panties, my fingers stared moveing in and out of her vagina.  KImberly started to moaning in her sleep, Kimberly started to wake up from her sleep. Jay why are you in my bed? and why do you have, your fingers inside of me, and fingering me? I'm going to have sex with you.  Kimberly said Jay you can not have sex with me, because I'm you sister. 

I said we can have sex with, each other because we have different father, as each other.  I reached down with my hands and hooked my finger's into the waist band of her panties, and started to pull the panties off of her body.  Kimberly parted her legs, were I could move between her legs. I got between her legs, and put my cock to the openning to her vagina, my cock was parting, her vagina lips with my cock.

I started fucking her with long hard strokes, my cock was hitting the back of her cervix.  I could fill my balls, get tight, I started pushing my cock all the way into her cervix, my cock started shoting my sprem inside of her fertile uterus.

 Kinberly said Jay you should not have cumed inside of me, I'm at my most fertile time.  you may have made me pregnate.
