Step-Sister Fulfills Brothers Dying Wish

I have bad news. My doctor ran some tests and it's not good. It looks like I have 3 to 6 months to live. I'm going to a virgin! My step-sister is my best friend. I tell her I have one last wish. I want to lose my virginity to her. She is reluctant at first and says she can hook me up with her friends but SHE is the only pussy I want! She jerks and sucks my cock so fucking perfectly. I can't believe she is doing this for me! She really loves me! I fuck her tight pussy and make her cum over and over. I finally get to cum all over her face!!! Is this really happening? Is this true? Am I dying? Did I just fuck my little step-sister!!???
