Introduce her to Mr. Johnson.

"What did Mr. Gavin tell you about Mr. Johnson, Jean?"

"That he was very important, and that I could learn a lot from him, Sir," she answers quickly. You smile, trying to keep the hunger out of your eyes. You've seen Jim Gavin's jokes before, and have a pretty good idea what this is about.

"He's right Jean," you tell her. "Shut the door and come over here." As she obeys you unzip your pants and pull out your cock, letting it's flaccid length lay on your lap.

The slender blonde walks back towards you. She's wearing a kind of sundress that comes to just above her knees and strappy low shoes. She turns the corner of your desk and looks down at your cock, her face going bright red with embarrassment.

"Sir! OhMyGod," she squeaks, looking horrified, and backing away.

"Calm down Jean," you tell her. "Mr. Gavin wanted you to ask about Mr. Johnson. This is Mr. Johnson. Mr. Gavin said you should do what I say. Have I got it right so far?"

She holds one hand to her mouth in shocked embarrassment, her eyes staring at your cock. "Yes sir, but...."

"You also said you'd been working closely with Mr. Gavin. Now unless Mr. Gavin has changed dramatically, that means you're already acquainted with Mr. Gavin's friend, Mr. Johnson."

"He called it Mr. Peters, sir," she whispers, gulping with embarrassment.

"And what did you and Mr. Peters get up to, Jean? Come on now, don't be embarrassed. No secrets here."

"I...I... took Mr. Peters in my mouth sir," she answers in a low voice, still staring at your cock.

"And did you make Mr. Peters happy, Jean?" She blushes even deeper, nodding silently, her eyes still fixed on your cock which is starting to harden.

"So. You're to do what I say. What if you don't?"

"I'm here on a grant program through the college I'm starting in the fall. Mr. Gavin said I had to do what I was told or he'd have my grant cancelled."

"So you're motivated to be obedient, Jean." You smile cruelly. "I like that."

"What do you want me to do, Sir?" she asks, trepidation in her eyes.
