One of your students comes in with some lame excuses why she could not finish the assignment on time. Big deal. Now only she really really wants to make up the work any way possible. She would do anything do change your mind since she cant afford to lose her scholarship. Best part is the she knows exactly how to convince you to let her do more. She does so much more, like sucking your hard cock and riding it that you simply give her an A in everything she wants.
