Mindy goes for a different 'B':

Mindy suddenly reached towards John's chair, grabbed his crotch, and said, “Gotcha, bitch!”

“Wha-?” said John, aroused by her tight grip on his Johnson but confused by her statement.

Mindy dropped her books onto the teacher's desk and reached into the small purse slung over her shoulder. She pulled out a cellphone. The word 'RECORDING' blinked on its little screen as she waved it in front of him.

All the blood drained from John's face. He reached for the phone and said, “Give me that!”

“No! Bad teacher!” Mindy yanked the phone away as she squeezed John's crotch hard, making him freeze in pain. She pressed a button on the phone and the screen flashed 'SENT'. “Oh, look at that, I just sent the recording of your offer to my friend Syd, same as I did with the last two asshole teachers who propositioned me. So now that that's done, why don't you lean back and relax while I explain how things are going to be, Doe.”

The punk girl let go of her teacher's crotch and shoved his chest, pushing him back into his chair. John had no idea how to react, so he just slumped in his chair as Mindy sat on his desk and looked down at him. As overwhelmed as he was, he still couldn't help noticing that her large breasts were eye level to him and her nipples were poking through her spaghetti string top.

Mindy flicked his forehead with her middle finger. “Hey! Eyes up here, Doe, this is important. I'll make this simple. You don't get to choose a grade, you don't get to choose squat. You're my little bitch boy now or Syd sends the recording to the principal and you lose your job and get run out of town.”

John stared up at her, but didn't say anything.

“For your first act as my ****,” said Mindy with a nasty snarl, “I want you to take off that ugly tie you borrowed from your grandfather and polish my boots.”

John looked down at Mindy's feet. Her legs, damn fine legs if he had time to really look at them, were crossed. She was wearing bulky black boots that went almost to her knees and had soles so thick they looked like they could stomp through concrete. They were the kind of evil looking boots that only a punk like Mindy would wear.

“Now!” said Mindy. “Get to it or I'll make you do it with your tongue!”
