Wants a whole month without sex but stepsister ruins the plan

That’s the dumbest thing I’ve ever heard. You don’t masturbate for a whole month? And you think that’s going to make you successful or something? Because guys on the internet told you to do it? Why do I have to have a stepbrother like that?… Well, that’s crazy. But it doesn’t matter, there’s no way you’re going to be successful for a whole month at what I’m going to do to you.
