Your words are lost in the sudden gust of air that rushes out of you as you reveal your massive, throbbing member. It's almost comical how small it makes Barbara seem in comparison, but she doesn't seem to notice or care. All she can focus on is the power she has over you right now.

Her eyes narrow slightly at the curse that escapes your lips, but she merely arches an eyebrow once more, challenging you to try and defy her again. "

You were supposed to undress slowly... but perhaps it's too late for that now. She decides to let it slide this time.

"Now," she says, her voice taking on a husky quality as she leans forward over her desk, "get on your knees in front of me." Her breasts sway temptingly above you as she waits for you to obey her command.

You nod slowly, feeling a mixture of excitement and nervousness well up inside you. The bell rings and students begin to file out of the room. As soon as the last one has left, Teacher Barbara motions for you to follow her once again.

She leads you down a deserted hallway until they reach an unused classroom with a large anatomy model in the center of the room. The door closes behind them with a click, and she turns to face you. "Now," she says, her voice taking on a commanding tone, "

it's time for your private lesson." She begins by asking you about your knowledge of the female anatomy. As you answer her questions, she moves around the model, pointing out various structures and explaining their functions in detail. Her tone is authoritative but also playful at times, as if she's enjoying teasing you with her knowledge.
