Kat and Kelly had been thinking a lot that week about their English teacher, Ms. Valentine, after running into her at the nail salon. She was quite gorgeous and sexy, and had an air of mystery about her. She mostly kept to herself, but all sorts of rumors floated around about her -- she was a religious nut, she was into BDSM; she had been a nun when she was younger, she had been in porn when she was younger. No one had no idea how much of it, if any, was true, but it made her the subject of a lot of curiosity.
As it happened they had been assigned to write a short story for English class that week, so working together, they had crafted a story about a high school senior who had a lesbian crush on her English teacher. They changed the names but the characters were clearly recognizable as Kat and Ms. Valentine. In the story the teacher also had feelings for the student, but hid them; then one day they happened to be alone in the classroom, and nature took its course.
They went through several drafts of the scene where the two finally acted on their passion, trying to make it hot enough to work on Ms. Valentine's imagination, but not overly graphic or explicit. They tried to be subtly suggestive and seductive, and it must have been working, because they ended up in bed together several times during the writing process -- a few orgasms to blow off steam, and then back to work.
On Friday when she was returning the graded stories, Ms. Valentine handed out everyone's except Kat's and asked Kat to stay after class to talk to her. Kat and Kelly shared a conspiratorial look as the class filed out, leaving Kat alone with the teacher.
After closing the door, Ms. Valentine walked over to her desk and pulled Kat's story out of her drawer, looking quizzically at her student. "Katrina... um, Kat... we need to talk about what you wrote here."
Kat assumed a demeanor or girlish innocence. "Yes?"
"You know that this is very inappropriate. If anyone read this we would both be in trouble, especially me."
"I'm sorry," said Kat. "It's just that you're so beautiful."
