I was minding my own business when my step-sister, Mia, walked into the room. She was only wearing a robe and that was all. I can not believe she could just come out in the living room like that, I guess she had something on her mind. She started to rub on my leg, slowly gliding it up to my crotch. I can not believe my step-sister is blowing me, I let her suck me off till I cum all over her tits.
