Keep fighting

As Miss Locke's sexy knee smashes your testicles, you by now are nearly totally at her mercy. Your arms flail in pain but are no longer any threat to her, as she exercises total control, grasping you firmly by the shoulders while holding her knee in your balls.

Encountering no resistance, Miss Locke sends a second knee into your balls, and you begin to feel light-headed. Your eyes begin to roll back and your vision becomes fuzzy, but not too fuzzy to see Miss Locke drive her knee into your balls a third time.

"What, did you think I don't know how to defend myself?" your teacher asks mockingly as you groan from pain.

"I've had to fight students before, but you are just too easy..."

As Miss Locke is talking you see an opportunity to finally strike her. You swing at her face, managing to rather ineffectively hit her jaw. She stumbles backward and you grab her ample breasts, squeezing with all your might to try to inflict pain on your teacher.

Miss Locke is unamused by this feeble attempt. With your eyes completely fixated on her boobs, she brings her arm back and slaps you viciously across the face, then immediately backhands you across your other cheek. She feigns a grab toward your genitals, causing you to jump back in reaction, but as soon as you do so her knee goes into your stomach, followed immediately by the same knee to the face, to the stomach again, and finally a real strike connects to the groin.

With your body practically folded over her, her knee jutting into your family jewels and your body curled over in pain, Miss Locke looks you in the eyes triumphantly, and proceeds her to jab both thumbs into your eyes that had been lusting for her for so long. In complete shock, your hands dart up to try to defend your eyes, at which point Miss Locke immediately reaches low and grabs your balls, squeezing with more strength than you ever imagined a curvy teacher could have. As she holds you by the balls with one hand and slaps you repeatedly in the face with the other, your body begins to convulse in debilitating pain.

Miss Locke, seeing her victory, releases her grip on your genitals and steps back for a second to admire the state she had reduced this proud masculine student to. You stand in complete shock, barely standing at all.

Miss Locke finishes you off with a final, massive kick to the balls. Your legs collapse as you writhe on your classroom floor.
