Handjob, to start...

"Unzip your pants, young man."

Jake stared, unsure he heard correctly. When he finally managed to speak, he croaked "Excuse me?"

"I said, unzip those pants, Jake. I'm waiting..." His mother insisted.

So Jake did just that, albeit very nervously.
What if there were still some memories of this later on? Locked away where some therapist could reveal them with a few sessions of hypnosis, or something?
Jake sat there, looking uneasy, dick sticking out the front of his pants, pre-cum glistening at the tip.

His mother wasted no time in sliding her chair closer, leaning over to grab it, and stroking slowly. She began gentle, and sensual, almost as if she *revered* the cock. "See? I may be stern in class, but I can be fun, too. No need to be nervous." She said in a soothing tone that somehow *still* oozed lust. Even as a professor, she kept a little of her skills in mothering, even though the rest of her personality is out the window for the time being.

Jake just nodded and let his head roll back while the pleasure coursed through him. His mother's expert hand knew all the ways to stroke, and grip, and tease his dick. She used tricks and methods he'd never even seen porn stars do. He felt amazing, but she wasn't letting him hit climax yet. She was torturing him, for the short term, before she let him have what he craved.

Jake brought his head back upright and looked at his mother/professor. Her face showed she was having the time of her life. She beamed with enjoyment. But was that also some mischief he detected on her?

No sooner did Jake finish that thought, that his mother let go of his dick. Jake was actually slightly startled at this, concerned she may blue-ball him for 'punishment.' But as he opened his mouth to speak, she held up a finger and shushed him.

"Jake, will you be a good student again?" She asked firmly.

Jake nodded frantically.

"Would you like to do this more often as... motivation?"

Again, Jake nodded with an intensity that would be hard to rival.

"Good! Then let's finish up here, and get you going. I have another class in a bit, and I'll need time to clean up." She said with a wink, as she grabbed his dick once again.

It only took a few final strokes from the virtuoso for Jake to blow his load all over her hands and arms.
He began to apologize, until his apology was muted when his mother brought her hands to her mouth and licked them clean like a cat. She scooped the cum from her arms as well, and lapped that up from her hands. She wet a cloth at the sink and used that to wipe away the remainder. Jake assumed, that she was assuming, they're in the science building of the 'college' campus. (I mean, it's the only building in most schools, where a sink is present in the classroom... Anyways!)

As Jake's mouth hung agape, the professor stood, and said with a sultry chuckle, "Now then..."
