his slutty step sister-family therapy

Step-Brother walked in and started me like he always does. I was trying to be a good step-daughter and make sure the house was clean. Our parents were coming back from vacation in a couple days. My step-brother hadn't been helping at all, but then he pulled out his phone -- IT HAD PICTURES OF ME SUCKING DICKS ON IT!!! I grabbed it but he pulled it away before I could delete the pics. They were from a party I went to last week, I ended up blowing like 5 guys. I swear I'm not a slut! I just got a little carried away...it was a really crazy party. My step-brother said he didn't know what a little whore I was and said it wasn't fair I was blowing all his friends and not him. My step-brother told me I had to fuck him or he would show Step-Mom and Step-Dad the pictures
