I have a step-sister who lives a self-indulgent life. She seems to sometimes bring a man she catches on the street to her room and satisfy her sexual desires. I love this slutty step-sister. One day, I confessed my feelings to my step-sister, and she allowed me to have sex with her for one night. Hey, step-sister? Which sex felt better, the rough guy from the street or me?
