She clucked her tongue at him, shaking her head. "Paul, you're being silly. Haven't I lived up to my part of the bargain so far? You've had your name on some very prestigious papers, you know."

He frowned.

"When the time comes for you to present your thesis, you'll have a thesis. Don't worry."

"I don't have all that much time left."

"You have as much time as I say you have. I can extend your term as my assistant almost indefinitely."

Paul was not comforted by that thought.

"Come here," she said, beaming at him as she patted the desk beside her.

His balls gave an agonizing throb. He didn't move.

"I said, come here, Paul," she repeated, removing her glasses. "You know how much I dislike being kept waiting."

He knew, all right. And he knew what was in store for him when he sat down. In the beginning, he'd looked forward to the little extra-curricular sessions, as the professor was a beautiful, sexy woman with a ravenous appetite for sensation. He didn't even mind when she started monopolizing all his time, as she was a thousand times more experienced than any of the college girls he was screwing, and she knew tricks that he didn't think physically possible. One time, after a particularly strenuous session, she'd let something slip about earning her passage to the U.S. by working on the Reeperbahn, Hamburg's notorious red light district, but Paul could get no more out of her about it. It was too bad, too, because the idea of his lovely lady professor, the distinguished author of "Polymerization of Synthetic Resins", taking on all comers in a Hamburg whorehouse turned him on all the way.

Things got strained between them after Paul met Joselyn… and immediately fell head over heels in love with her. He couldn't help himself. For one thing, she threw herself at him and for another, she was the equal of Dr. Blensch in the sack. She was just as skilled in love making and a good fifteen years younger and a hell of a lot tighter where it counted.
