Danny Steele, a high school principal, gets a surprise visit from Serena Santos, a former student of his who is now in college. Serena hints that she's learned how to do some VERY sexy things in college, which makes Danny a bit jealous. She offers to get frisky with him, but Danny isn't sure that would be appropriate. She points out that she's over 18, plus she's not his student anymore, so there's nothing wrong with having a relationship. Besides, he's the school principal, so he's not going to send HIMSELF to the principal's office over this, is he? Nobody has to know about what they're doing. They kiss, and Serena begins to show Danny all the sexy techniques she's learned in college...
