(This is a fictional story. All characters are 18+)

This was my senior year of high school. I was sitting in the class bored to death. Little did I know my life would irreversibly change that very day.

Our teacher was a stunning woman in her early 30s. She wore a loose black skirt that fell just above her knees, paired with nylon stockings, red high heels, and a white blouse with a deep V-neckline that hinted at her ample cleavage. Her legs were the perfect embodiment of feminine power - strong yet elegant, capable yet graceful. There was something inherently dominant about their shape, a natural authority that came from their very form. Her red bra was visible through the thin fabric of her shirt.

As I sat there, my eyes got mesmerized by her cleavage. She was grading some tests and gave us an assignment to complete in 10 minutes. Seeing this as an opportunity, I decided to take advantage of the situation. If I started touching myself now, no one would notice.

Watching her breasts bouncing slightly as she marked the paper reminded me of the times I’d seen her jogging near the school; I couldn’t tear my eyes away. I slipped my hand below the desk and began to stroke myself slowly.

“OK, class, so did anyone finish the assignment… Oh… What are you doing under that desk, Gerry?” - She said with disgust on her face. Suddenly the entire class fell silent, their eyes fixed on me. My face burned with embarrassment. “Did you hear me? I asked, What are you doing under that desk?” she repeated, her tone shifting from curiosity to disgust as she strode toward me.

“Stand up. Now.” She said, standing in front of my desk with arms crossed, looking down on me with an expression on her face suggesting she wouldn’t tolerate any further disobedience. My legs were trembling as I began to stand up. “I knew! You little pervert!” she hissed, her eyes locked onto the bulge in my pants “Did you really think I wouldn’t notice that you are touching your little pee-pee while staring at my breast? I was expecting you were a fucking pervert since I saw you in the park staring at me. But masturbating in a class is on another fucking level. I need to think about your punishment.” I could hear passion in her voice.

“I—I—it’s not what you think!” I stammered, my face flushing deeper. My legs shook violently, like I was about to fall from the embarrassment. “You must have misunderstood!” Her lips curled into a smirk. “Is this really all you have to say?” Before I could respond, her hand shot out, gripping my testicles with surprising force. Pain shot through me, and my eyes widened in shock.

“Now go to the front of the class.” She said as her grip let go. My legs were trembling, and the only thing keeping me from falling was the desk in front of me. My mind was consumed with the throbbing ache in my groin. “I said something,” she repeated, her voice sharp enough to cut glass, leaving no room for defiance. I could barely move, my legs trembling as I stumbled forward. The rhythmic sound of her heels clicking against the floor echoed in my ears as she returned to her desk.

“Pants off!” She commended me as I stood there in front of the class. I hesitated for a second, but her dominant stare left no room for refusal. My fingers trembled as they found the zipper of my jeans. I started pulling them down, not understanding what made me follow her commands. Fear, I thought, but there was something else, something that awakened in me that day. I actually enjoyed being dominated. The uncertainty of what came next sent electric pulses through my body, making my hands move almost independently of my will.

She could make me do anything.

“Oh… You actually are small down there… Even smaller than I expected. To be honest, I’ve never seen a more pathetic excuse of manhood.” laughs giggles I heard girls laughing as my dick started twitching on those words. “Owww… Your little pee-pee is enjoying it when I mention its inadequate size.”

“Spread your legs, boy.” My body immediately obeyed her order. I didn’t know what she was about to do, but I felt anxiety as my subconscious mind already knew what was about to happen next… “Let’s see if it also likes this.” She whispered into my ear as her knee was crushing my testicles with brutal force. I immediately fell to the floor. I could not even enjoy the fact that on my way there my face briefly landed against her chest.

I lay there naked, on the floor crying, as the entire class watched. I thought she actually popped my balls.

“Let’s see how your balls are doing.” she forcefully spread my legs, so my junk was for every one to see once again. “They’re fine.” She slapped them hard for emphasis.

“You will count down from 10,” she said, her voice sweet yet playful “after each number, I’m going to slap you. For every second of hesitation, the force doubles. Understood?” … “I mean the game started already; better start counting now if you don’t want to get castrated from just this one slap.” She whispered into my ear.

10… SLAP

I squirmed. The pain was unbearable. I thought she actually crushed them this time. “They’re fine,” I heard her sweet voice. “Better continue, though…”

9… SLAP

I was breathing heavily.

8… SLAP

Tears streamed down my face.

7… SLAP

6… SLAP

I rushed through the numbers, desperate to end the torment

5… SLAP

“We are halfway through.” Her sweet voice entered my ears.

4… SLAP

My entire body was shaking.

3… SLAP

I don’t know how I managed to speak at this point.

2… SLAP

“Just one more left.” I heard her innocent voice.

1… PUNCH

I was lying there in pain for a few minutes, completely humiliated, holding my balls.

“Let’s use this incident as a lesson for all the girls on how to handle disrespectful boys. And boys, this is the power women have over you. This might happen to you if you arouse their anger.” I heard her voice through the pain. I could hear heels clicking as she walked around the class.

“In fact, many girls withhold the power they have over men because they are afraid they might damage their testicles. But as you could see, testicles can endure quite a lot of damage before they break… unlike the man attached to them…” Girls giggling and laughing

“I believe men were born to be slaves of women,” she declared, her voice taking on a lecturing tone. "Physically stronger than us, making them perfect for doing all the hard labor for us. Yet they possess a fatal weakness - an easily accessible vulnerability that gives us ultimate control. It allows us to enforce obedience… and provides endless amusement as they crumble before us, reduced to tears by a single well-placed kick.

“Now I’ll demonstrate the fundamental power imbalance encoded in human biology itself.”

“Stand up, boy.” I didn’t want to be ballbusted again, but I also feared her anger; besides, I just could not resist the dominance in her voice.

“Are your balls better now?” The sweetness in her mocking voice almost could relieve my pain. Almost…

“Anyway… Spread your legs for me again, boy.” My body obeyed her, even though my legs were shaking as if I was about to fall again.

“Good boy.” Her praising words send a shiver of submission through me. I wanted more, even though I knew how humiliating this was.

“Th… Thank… Thank you… mistress,” I cried to the amusement of my teacher.

“So let’s begin our little demonstration.” She said as she lifted her skirt to the excitement of all the boys sitting there. The sight of her red panties made my dick and balls happy even through the pain. Which in turn made me even more vulnerable and submissive.

“Now try grabbing between my legs.” Without hesitation, I reached forward, my fingers pressing against her through the thin fabric. The moment I made contact, the earlier pain in my groin faded into insignificance. She was already wet, her arousal evident beneath my trembling fingers. “Squeeze as hard as you can,” she whispered in my ear, her breath hot against my skin. “Don’t be shy. Show us all your strength.”

“Even though it is a bit painful,” she murmured, “I am still standing. Which can’t be said about you…” I didn’t realize when she grabbed my balls, but now I was on my knees in front of her making sounds I didn’t know I could. In that moment of utter submission, I truly realized the absolute power women held over me.

“Please let me go…” I begged through my tears. “I will do anything for you. I will be a good boy now. I won’t ever disrespect you - or any woman - again.” She released me.

“See, girls? This is how you handle perverted men… or just any men who disobey you in any way. Don’t worry about their balls. They are not as easy to pop. Besides, even if they do, it is not that much of a loss… At least not for you.” Girls giggled to the terror of all the boys.

“So I want every girl to practice ballbusting now.” She announced. I froze… My eyes widened in terror as I didn’t even start recovering. “Don’t worry,” she continued with a cruel smile, “it won’t be your balls… at least not only yours.”

“I did not give anyone permission to look at my panties as I lifted my skirt,” I heard her strict voice. A collective shudder passed through the boys. We understood exactly what that meant. All the boys felt the terror as they realized this also applies to them and their balls…

I lay in my bed. The aching in my balls served as a constant reminder of the ballbusting I received from my teacher and some female classmates. Each throb brought back memories of my teacher’s dominance and the undeniable power women held over me. The cold metal of the chastity cage around my penis offered no relief from the arousal those thoughts provoked.

“The best way to ensure submission is to keep them in chastity and allow only edging. Eventually, they will beg you for more kicks just to be allowed to cum.” My teacher’s final lesson echoed in my mind. That’s a subject for another story, though.

This is my first erotic story. Hope you enjoyed it :). Feedback welcomed.
