Hey big step-brother, I wanted to tell you something. I saw you in the shower. I saw you jerking off. You had a pair of my panties in your hand. Do you have a crush on your little step-sister? Cmon, you can tell me. How do you feel about these panties? They are getting really wet. You know, we really shouldnt be doing this but I know how much its turning you on. Pull out your cock. I know you want this too.
