Housecleaning or BJ from a stepsister?

That day I decided to unwind after a long, hard week at work. I was enjoying a cup of joe with my eyes glued to the TV. My stepsister was bustling and hustling around while cleaning the house. The thing is, our parents f***d her to clean the house today despite her plans to go to some party. After a few hours of housework, she was understandably upset and annoyed – she even tried to convince me to help her out, but I was too tired to even entertain the idea. Suddenly, her slutty short skirt gave me an idea! “Hey, stepsis, I can help you with housecleaning but there’s one condition: I want you to grant me FULL access to your pussy… It’s your call!” She didn’t know how to respond… Guess what happened next?
