The other day I was just chilling in my room when I heard some noises coming out of my step sister's room. My dad wasn't home and her mom wasn't home either, I decided to go see what was going on, I knocked on her door but she didn't respond so I decided to open it and guess what, she was there laying on her bed masturbating... I told her that I would tell her mom what she does when she's home alone. Apparently she didn't like that idea and told me she would do ANYTHING for me to not tell. My step sister is pretty hot and I know she's a total slut so I jumped on the occasion to have a little fun! She blew me before I started pounding her tight little pussy that was already all wet from masturbating, I fucked her for a while and then I wanted her to suck the cum out of my cock which she did! We finished just 5 minutes before her mom got home and she asked why we both happened to shower in the middle of the day like that? We said that we went jogging together that's why. ;-) Good times!
