Filthy POV - Blackmail Sex Is The Best Sex

I knew my step-sister, Melody, had been sneaking out all the time, this time I was gonna bust her. I wait in her room in my underwear knowing at any minute she is gonna crawl through her window. As I was about to give up, I hear the window slide open and sure enough, there is my step-sister coming through the blinds. I tell her if she wants me to keep my mouth shut Melody is gonna have to fuck me, why else would I be waiting in my underwear. I always thought she was so hot, at first Melody is really annoyed with me but she knows she will get grounded if Step-Mom and Step-Dad find out. I have my way with her and even cum deep inside her pussy, she freaks out after she sees all my cum drip out her pussy.
