Your step-son is failing miserably at school. He just isn't happy this term. In my years of experience, I've learned that this behavior often starts with a poor life at home. I know this is personal, but are you having any issues that could be affecting his academic performance? Are you, perhaps, having performance issues yourself? If you're unhappy it's making him unhappy. This usually begins in the bedroom. Are you and your wife experiencing any difficulties of a sexual nature? If your wife isn't putting out then you must have a back load of cum in there. No wonder you're miserable. Thankfully, I can help with that. I will always go the extra distance for my students and I'm sure you will do whatever it takes to make sure your step-son's grades improve. Now, let's get your balls drained so I can get on to the next appointment.
