My step-dad has been teaching me for a few years now how to please a man. He tells me that he wants me to be the best at making guys cum. My step-dad usually has me practice on him but he told me that he wanted me to practice on my step-brother. Try my skill out on another cock. So I did as my step-father asked and pleased my step-brother. I stroked and sucked on his cock until he came in my mouth then slid him inside of me and took all his cum in my pussy. Just like step-dad wanted me to. step-Mom and step-brother were out shopping so I finally got to tell step-dad about it. He was very excited to hear about it and fuck the pussy that my step-brother also came in.
