"Suck my dick"

"...suck my dick," Ms. Nanci finishes, her arms crossed over her chest.

"Suck...what?" you say in a panicky voice.

"You heard me. Get under the desk, or I'll fail you out of english!" she commands.

You hesitate for a moment. You definitely do not want to suck your English teacher's cock, but there's no telling what our mom would do if she found out that you failed english class. You decided to just get it over with and you unsteadily crawled under Ms. Nanci's desk.

You're really sucking with gusto now, your mouth making loud, wet noises every time you bring your head back and forwards. Your moan loudly as you can feel that you're close to cumming.

Suddenly, you feel Ms. Nanci's hand stopping your head. "Someone is at the door. Keep going, but do it quietly," she whispers. You nod and resume sucking her cock.

"Come in," Ms. Nanci says.

"Hi Ms Nanci," you hear a female voice say. Suddenly, you realize who it is. It's...
