Stepsister's double let down

My stepbrother... hah! He's always asking me to do things for him and it drives me nuts, so I don't always follow through. Like, sometimes it's the dishes. Okay, I leave some out on the counter instead of putting them in the washer. Or if I don't make the bed *just right*! Who has time to tuck sheets in every day? Well, he can't expect me to finish the job every time. I need a way to really show him I'm not doing what he asks all the time... Hmm. He's so sex starved. I know a job he can't refuse! I wonder if he'll think I'll actually let him finish his orgasm. He'll be so excited to have someone touching his cock. This will definitely get my message across. With my soft hands, who could resist?
