Most people assume that it is the bad bad teacher who seduced the poor innocent student but maybe the increase in such cases in recent years is due to the high-school dudes being more confident and/or less wary of consequences and they are the ones initiating contact and insisting, seducing the teachers. Maybe the high-school male students are more inclined by current mass media to be sexually active and see a decent-looking teacher as a badge of honour.
I only taught at university level and was by no means superhandsome but I had to say no to two second-year lady students in my 15y career. Grades have become so important now that some students are willing to boink their professors for a grade increase. Some will even threaten the prof with false allegations (one reason why we had to keep our office doors open when talking to a student). Even when proven innocent, the stigma of false accusations of sexual misconduct will irrevocably damage one's career. I saw this happen to one prof at another university.
Anyway, maybe it was not for a better grade but I have a feeling that current high-school dudes are more openly sexed up and that some will take advantage of cute profs if given the chance. The female prof may resist at first but the student can be tenacious and finally get her at a vulnerable time in her personal life.
Of course, there are also cases when the teacher is the oversexed one but I think that the media tend to underestimate the student's role in the affair, even though legally the prof will take the whole burden.
It takes two to tango.
Edit: as for the picture, it's a mugshot. She probably looks great in person with a smile on her face.
