Trying to get pregnant just like my sister

Dear Diary
The other day my hormones were getting the better of me and I decided to go out looking for a man. My pregnant sister Sadie asked me where I was going and when we started talking I realized I was trying to get pregnant like her. She was so understanding and helpful she even called in our step-dad to do the deed.
It was a little strange at first but once his cock was in my pussy all I could think about was getting pregnant. I rode him harder and harder begging him to fill me up. Sadie was getting turned on too and started massaging her swollen tits. The site of his step daughters getting that hot pushed daddy over the edge and he exploded inside me. Sadie pulled my legs in the air to keep it all in and everything.
