This teacher learnt to her chagrin that exchanging naughty photos with a lover is not always a great turn on.
How can it if you accidentally send it to a student? Unfortunately, a namesake of her partner.
Well, she was oblivious of the mistake, and teased her partner -- did he want some more?
The student was in no hurry to correct her. He answered: "Definitely". But he had to put a stop right there when she sent her next message -- with another revealing photograph. "Can't wait to see you tonight," came next.
What she did next was quite unbecoming of a teacher! But then, we do all kinds of foolish things when embarrassed. She offered the student an “A” grade in her subject if he promised to delete the pictures and didn't talk about this with friends.
The student did as ordered and the teacher fulfilled her promise. That is what we call a happy ending.
