Step sister impressed with how big her brother's cock has gotten

I confronted my step sister after seeing her stripping at a club last night. She is so fucking hot! It was awesome to finally see her naked. She begged me to not tell our parents or her real dad. She is working there while going to college, but her dad would cut her off if he ever found out. It's nice to have something to hold over your hot step sisters head. She offered to give me a hand job, pulling it out, I could tell how impressed she was with how big her brother's cock has gotten. Then she just shoved it in her mouth. It felt so good. Her hot wet mouth sliding up and down my shaft. She wanted this to happen as much as I did. She took off her clothes putting my cock between her big firm titties, then back in her mouth. Sucking and stroking me until I came all over her pretty hand. I think I will keep her secret and visit her at the club more often. I wonder if I can get a family discount on a lap dance?
