Stepsister broke your wrist

Wow, I saw that! I know what you were about to do, Big Brother. Hey, don't feel embarrassed. I understand. I'm really sorry I broke your wrist... your dominant hand, of all things. But you shouldn't look at me when I'm in the shower! Who does that to their stepsister? Well... Look, I'm about to go out on a date. Mom and Dad won't be home tonight and you have the place to yourself, but is there anything I can do? Do you need my help? It's only fair since I was the one who broke your wrist. I know you want me to. You probably haven't been able to jack off for over a week now! Let's just keep this a secret between you and me. No telling! It's just a handjob, what could it hurt?
