I'm so glad you are part of the family because I have a situation I need help with and I can't talk to my parents about it. You see, I was snooping around my parents bedroom and found a dildo that belongs to my step-mom. I was so grossed out by the size of it that I had to show it to my step-brother! I wanted him to see what a cock slut his step-mom is. Not only was he fascinated by the thought of his step-mom fucking herself with this huge fake cock, it also aroused him. Since we were laughing together and having fun in a sexual kind of way over this dildo, I decided to help him out with his boner. I gave my step-brother a handjob. I thought it would just be a one time thing since it was spur of the moment then over and done. The problem is that now he wants more. He does hand signals to me right in front of our parents that would indicate he wants me to touch his cock. I don't know what to do and I don't want our parents to find out what we did.
