There's one more lesson you need to learn from your naughty teacher during summer school. You need to practice being a good boy who can follow directions. Show me that you're capable of following instructions by playing this jerk off game with me. You stroke when I tell you to, and you stroke how I tell you to. Match my hand motions as I demonstrate on my dildo. Then, at the very end, follow my final directions when I guide you through how to eat your own cum for me. Don't back out now, or you'll never pass summer school. Drink it up.
