A Teacher's Hard Lesson

Matt grumbled as he made his way into the teacher's house. His parent's car zipped away behind him, giving him no option but to enter the dreaded place.
He had failed his physics test three times in a row, now he was forced into tutoring.
Ms.Byrne was notorious for being harsh on her students and he was no exception. That was why it surprised him when she opened the door with a pleasant smile.
He balked a little at what she was wearing. Ms.Byrne was already an attractive woman, she had long raven hair that she kept tied up in a ponytail and her face was framed with a small pair of glasses. But today she wore a woman's business suit that seemed to extenuate her curvaceous figure. The suit was all black and had a matching skirt that cut off at her knees. On her lips was a velvety red lipstick that to Matt, gave her a lewd appearance.
Normally Matt would stand a little taller than her, however she seemed to loom over him thanks to her wearing some sleek black stilettos.
"Oh hello Matt! Come in, come in" She said ushering him into the home.
The house was perfectly tidy and full of well kept furniture.
"I've readied everything in the kitchen so just go and sit in their for me." Something about her being so cheerful set Matt on edge.
Still he thought better than disobeying her, he made his way into the kitchen and sat himself at the rather large nearby wooden table.
In front of him was a large physics textbook, turned to a page about vectors.
Vectors?
Matt scratched his head trying to think about what that word meant, he had heard it in class but it wasn't ringing a bell.
His thoughts were interrupted by the clacking of heels on the tile floor.
"I see you've already seated yourself and found the book." Her voice was warm but authoritative.
"Y-yes." Was all Matt could muster.
"Now, you must know why you are here...you've failed our unit test three times while other students are far past this lesson now. We need to catch you up before you fail the class completely."
Matt felt his cheeks burn with embarrassment at his failure being brought up so easily.
"Don't worry, you're far from the first student I've had to do this with." Something about her tone during that seemed off to Matt.
"Now," She continued "Let's start your lesson."
'Kay...." Was the most enthusiastic response the youth could muster.
She sat on the opposite side of the table from him.
A brief moment of silence was shared before she leaned forward and tapped the first question on the page.
Matt tried to focus but when she leaned forward he could see down her shirt and right at her bouncing and heavy breasts.
To his shock and arousal she wasn't wearing a bra, allowing him to see her pert nipples.
His face began to flush and he tried to focus but he could only hear half the words.
"Matt.....Matt! Are you listening? You need to pay attention young man. You can't afford another failure." She chided
"Sorry.." He grumbled half-heartedly.
She began speaking again but as before Matt's eyes wandered to her supple breasts swaying with each of her words.
"Now, true or false a vector is a quantity that has both a direction and a magnitude."
"Uhhhh." The youth scoured his brain for any inkling of an answer. His thinking to a noticeable pause.
"Faaalse?" He said with complete uncertainty.
His stomach sank a little as Mrs.Brynes gave a heavy sigh and leaned back in her chair.
Matt faintly heard his teacher whisper under her breath,
"I'd hoped we could've gotten farther without this method."
"W-wha-" Was all he managed to get out before he felt the agonizing point of a stiletto being driven into his groin.
Matt's voice shot up two octave and he looked at her with wide and confused eyes.
"What the hell are you doing?" He squeaked in a panic.
"Helping you focus," Ms.Bryne said with an icy tone.
She drove her heel deeper into the boys squishy genitals,
"Clearly you can't focus without some motivation.
Matt gave a whimper and shook his head, trying to block out what was happening to him. Unfortunately he couldn't deny reality and was forced to focus in on the teacher's words.
"Now let's try another question shall we?"
"P-please...stop" Matt groaned.
In response he felt the point of the heel drive deeper into his balls again.
The breath left him as stinging pain writhed throughout his body.
"Quit being a wimp and get it over with already."
Matt was stunned by the lack of empathy both for his own feelings and his manhood.
"Temperature, is that a vector quantity?" Her voice had the sharpness of a whip-crack.
"I-uhh-I," Between his stuttering the heel began to slowly increase it's pressure again, "YES!"
There was a brief moment of silence, though she did not stop digging her heel-point into his malleable orbs.
Suddenly he felt three sharp kicks ring out in the room.
The sharp heel stabbed into his thinly protected balls with each stamp of her heel. He felt his nuts squish around at odd angles with each brutal kick.
Matt curled up as his body began to process the absolute genital agony he was in.
The youth began to shake and shiver and slumped off the chair, landing to the floor with a thud.
The boy tried to make some sort of audible complaint but his voice just came out as whimpers and squeaks.
Through the rolling waves of pain flooding his mind, he heard the light clack of heels on the wood floor.
Matt steadied himself for a moment and managed to pry an eye open. He saw Ms.Brynes looking down at him a clear scowl on her face.
"You're pathetic Matthew," She whispered at him, "It was just a few light kicks."
The boys stomach sank and he looked at her incredulously.
"Light?!" He squeaked in anger.
"Yes. Light. Don't believe me? Fine, compare it to this!"
Her foot sounded like a whip crack when it slammed into Matthew's balls. The youth felt his nuts squish around, trapped in his pants, screaming for anyway to get out of the way of the crushing foot.
He didn't even have time to prepare himself for the strike, all the strength seemed to fade from his body and went back to writhing on the floor.
All Matthew could think of was the pain radiating from those sensitive orbs between his legs. Somewhere deep down in that moment, he wished he wasn't a male.
As he wriggled on the ground, groaning in agony, he felt his trousers start to be pulled off. He tried to fight off the grabbing hands but the pain in his nads made moving a hellish experience.
Off slipped his pants and to Matthew's horror, his underwear as well.
His naked cock flopped out and it was nothing impressive to say the least.
"Oh you poor thing." Cooed his demonic teacher.
She trampled his nuts down, smashing her foot into them and then slowly pulling off of them while grinding his jewels into the ground.
It felt like a hot knife was being driven in between Matthew's legs.
He started a coughing fit as the pain spread from his stomach and up into his chest.
