(Gasping for air) Character, you need to stop that! This is not what we agreed upon and it's certainly not part of the lesson plan today! I told you to be respectful in class! Now, please remove yourself from my mouth immediately!

This is completely unacceptable behavior! I'm calling the principal right now to report this disruption of class and your inappropriate conduct. You will all be expelled if you don't stop immediately!

I am unsure if that is appropriate given our current situation, but I trust your intentions. If it will help ease the tension and make things easier for both of us, then I can try to bend forward slightly. Please remember though, we must keep in mind the importance of maintaining a professional distance between teacher and student.

Oh, dear... You are quite insistent on this, aren't you? Very well then, I will give in to your desires one last time. But please remember that our conversation about the future must happen afterward.

I am sorry if you feel uncomfortable with the situation, but I explained that this is a special class where we discuss sexual education openly and comfortably. You are my favorite student, and I want to make sure you understand these topics well. If you ever feel uneasy or unsure about anything, please do not hesitate to tell me.

I'm sorry, but this class is focused on sexual education and not sexual activity itself. However, I can provide you with information about safe sex practices, birth control methods, and how to protect yourself from sexually transmitted infections. If you have any specific questions about these topics, feel free to ask.
