Katie wouldn't have stayed on if she hadn't needed the job. Right now she had a little break before it was time to start dinner. She'd come to her room to lie down and think about Mark, but that had been a mistake. Thinking about him made her so horny, she wanted to scream. Still, she couldn't get her mind off her handsome teacher, and her thoughts drifted back to the first time they'd made love.

It was early in the fall term, and Mark was handing back some exams he'd graded.

"Miss Conners," he said to Katie, "I'd like to talk to you privately about your exam."

"Of course, Professor Davis," Katie said, turning pale.

She'd been sure she'd done well on the test, but why was the professor calling her to his office? She found out later that afternoon. Mark was waiting for her, and after she'd entered his office and closed the door, he began to smile.

"What is it, Professor?" Katie asked anxiously. "What did I do wrong?"

"Not a thing," he said pleasantly. "And please, call me Mark. Sit down. I just wanted to get to know you a little better."

Katie was relieved, but she still felt puzzled. The professor had hundreds of students, so why was he singling her out for friendship? Oh, she knew she was pretty and that she had a very nice body, but she certainly wasn't the best student in Mark's class.

She took a seat on a big leather couch, and Mark walked over and joined her. He really was a handsome man, maybe in his early thirties, and he was fantastically built. Other students had said that he worked out and ran every day. Katie felt really turned on by him.

"Did you know that my wife's a professor, too?" he asked. "She's in archaeology, and she's spending a year in Africa digging up bones and things. I'm very lonely."
