Knee:
“Alright girls, welcome to morning self defense class,” Sergeant Lori said, bundled in her coach gear. “We’ve spent the last few weeks practicing our fundamentals. Eye gouges, nose palms, basic grappling, and I know you all love our practice dummies,” she gestured to the large stuffed body pillows on the floor which had both seen better days, the girls did not seem impressed. “But today I have something better. Today, you get to practice on real live training partners.”
Lori gestured to the two boys standing behind her.
“This is my cadet Billy. You may know him from constantly trying to write you up despite being a student same as you. Well, as desperate as he is to prove he’s a big tough man, he couldn’t even arrest a drunk freshman girl. Could he Gina?”
“Nope,” Gina said from the group of girls in attendance. “He wouldn’t fight me because I’m a girl, so I tried to take away what makes him a boy, to make the fight fair.”
The class giggled.
“Yes he really did just stand there and let her bust his balls like an awkward little incel, but for our purposes that’s a good thing,” said that sergeant. “For that night I discovered that despite being unwilling to fight, he can more than take a hit himself. So he’s going to stand here and let you all practice today’s move on him as many times as you need to.”
Billy tried to look tough, but Lori had really taken the wind out of his sails with those comments. As did Gina with her emasculating grin. As did seeing how all the practice dummies had torn seams between their legs.
“Don’t forget your other volunteer,” Gina teased.
“I haven’t,” the sergeant replied. “Class, this is Ryan.”
“Hi Ryan,” the girls all said.
“Billy and I caught Ryan here smoking the devil’s lettuce in the forest.”
“Gina was there too,” Billy protested. “Why isn’t she up here with Ryan and I?”
Gina stared daggers at the cadet.
“Because,” Billy’s sergeant told him, “men assault women at a much higher rate than women assault men. All women must be prepared for such a possibility, where as you boys don’t have to worry so much. Rest assured, a punishment has been planned for Gina as well, but for today she is just another innocent girl trying to protect herself from danger.”
Gina gave her most innocent look. “That’s right Billy, I need to be able to protect myself from incels. They might not all be as afraid to fight girls as you.”
Billy flushed red as the girls laughed at him. He hated it when girls laughed at him. Gina laughed beautifully at her own joke, but behind her smile was something fierce.
“Alright girls, that’s enough. Self defense is a serious subject. I want you all to focus while we practice,” she noticed the tone of the room turn down instantly, and felt she overdid it. “But that doesn’t mean we can’t have a little fun with it. Since this is technically a punishment for both of our volunteers, how about we turn it into a little contest to see who can take the most hits?”
“And what happens to the loser?” Cyndi asked politely from the audience. “I mean, it’s not much of a competition if there aren’t stakes. And since this is a punishment it should be something painful.”
“Na, they’re going to be hurting plenty after this. It should be something humiliating instead.”
“Ooh that sounds funny,” said the redheaded Melanie sitting in the class.
“Halloween’s coming up,” Gina said, “how about the loser has to wear a really embarrassing costume?”
All the girls quickly agreed through their giggles.
“Where’d you come up with that idea?” Ryan asked horrified.
“It’s my punishment,” Gina blushed.
“She wants to be the party girl,” Lori said, “let her be the party girl. I’m going to put a box outside the campus police office where all students can vote on what she’s gonna wear for halloween. And she has to wear it all night.”
Ryan couldn’t help but fantasize about all the different things Gina could be forced to wear. The fantasy caused him to stare at her boobs for too long.
“Careful Ryan,” Gina warned. “Right now I want Billy to lose. Don’t do anything to change that.”
“Then it’s settled,” Lori said. “The girls will all take turns kneeing the two of you in the balls, and whoever falls on the ground first has to wear a halloween costume the girls vote on.”
“Pardon me, coach, but since this is a competition, wouldn’t it be more fair if the girl who made the loser fall got to decide what they wore?”
“Oh that’s a great idea,” Gina said. “That way I can make sure Billy’s wearing something even more embarrassing than whatever I’ll have to wear!”
“If you win,” Cyndi reminded in a friendly tone. “And since the punishment for losing is humiliation, and not pain, I will just have to make sure that the competition itself is very painful.” She noticed the horrified looks Billy and Ryan were giving her. “What? I’m just trying to help.”
“The is all well and good, but remember, this is about self defense. The most important thing is that you be able to use this if you need it. So be sure to give these boys your best knees. And boys,” she turned to the two boys, “I expect you each to stay standing at least until everyone has had a chance to get one solid knee. Now will the first two girls please step forward.”
Melanie stood in front of Ryan while Elaine stood in front of Billy. On Lori’s count they each put their hands on their sparring partner’s shoulders and lifted their knee into his balls. Melanie’s knee went flying, sending Ryan’s balls into his throat. He put his head on the redheads shoulder, and she thought about letting him fall there. She could’ve won the contest right away, but what fun would that be? So she waited until he was able to balance on his own feet before going to the back of the line.
Elaine on the other hand had not lifted her knee too hard. Billy was still standing. “I’m sorry,” she said. “But I just can’t do it.”
“Elaine, don’t think of him as your classmate,” Lori said. “Think of him as an attacker.”
“That’s just it,” Elaine said, “he’s not scary, just look at him.”
“Billy, scare her so she can defend herself properly,” Lori instructed.
“I can’t do that.”
Lori growled, got behind Billy, and flicked his nut from the back.
“OW” Billy screamed, quite forcefully in Elaine’s face.
“AH” Elaine screamed in fear before her knee rushed into Billy’s balls. Billy clutched them in agony, not letting himself fall to the ground.
“Very good, Elaine,” Lori said. “Next two, come on, we only have an hour.”
And on the hour went. Every girl getting many chances to send both Billy and Ryan’s balls into their throats. As this was happening the boys noticed two girls in particular really knew how to knee a scrotum.
One of those girls was Gina, who despite saying she wanted Ryan to win, had no problem firing her boney knee into his balls as hard as she could.
“I thought you wanted me to win,” he said to her as he bent and extended his knees several times to keep from entirely collapsing onto the floor.
“I want you to earn it,” Gina said, before getting back in line.
The other top nut knocker was Cyndi, who not only fired her leg up so swiftly that it caught Billy by surprise every single time, but she also held her knee against his pelvis longer than any of the other girls, and made sure to grind her knee in so his balls were also pressed harshly against the bone for a while.
As the hour drew closer to an end, Cyndi spoke up. “Excuse me coach. This may be rude to say, but by now you must have noticed that Gina and I have the best form in the class. I think it is only fair that one of us gets to choose what the loser wears. Would’t you agree, Gina?”
“I guess…” Gina said. “So what, you gonna let me choose?”
“Goodness, no,” Cyndi said. “Where’s the sport in that? I was going to suggest, with your permission coach Lori, that Gina and I each choose one of the boys and we knee them in the balls at the same time until one of them loses.”
“What if you want to knee the same boy?” Lori asked.
“Oh I don’t care who loses,” Cyndi admitted, “Gina can choose who she wants to knee, and I’ll bring the other one to the ground.”
“Are the rest of you ok with this?” Lori asked the class, who nodded enthusiastically.
“Very well,” Lori said. “Gina you may choose who you wish to knee.”
Gina walked over to Ryan, and looked him in the eyes. “It would be so funny if I chose to beat on you right now. The look on your face would be so cute. But, I just can’t stand this incel cop. He deserves to have balls to sore to fuck for weeks. And I want to give them to him.”
Gina took her place in front of Billy, and Cyndi stood before Ryan, not caring whose nuts she racked. They were both being punished: she could pop either of their testicles and it would be justified.”
“Ready girls?” Lori asked. “Three. Two. One. Knee!"
BAM BAM
While Gina led with power, and Cyndi led with precision, both girls knew how to rattle a pair of balls.
“Again,” Lori said when neither boy fell.
BAM BAM
The game went on for twelve more rounds. Neither boy wanted to lose. Billy knew that if Gina won she was going to take out all her frustration on him. Well.. technically she already was doing that, but this pain would end eventually, if Ryan would just give up already, Billy felt he had to hold out, because he knew Gina would make sure he was even more humiliated than she was if she made him lose.
Ryan was facing a similar stress. Cyndi was so methodical with her knees. He never saw them coming. It was her eyes, they were so calm and sincere seeming, they somehow managed to make his body lower its guard every time, even though he should’ve known there was about to be a knee in his nuts. But if was a surprise every time, and every time it was a fresh spike of agony. She had such an innocent vibe to her, but the way she racked his balls told Ryan that there was more to her than what was on the surface. He had no idea what to expect from her if he lost, and he wanted to keep it that way.
Boy both just stood there, taking knee after knee after knee, desperately hoping this would be the round to send their opponent to the floor.
And finally, after a particularly rough knee that came within one inch diameter of rupturing a nut, a boy fell to the ground.
A girl smiled in satisfaction
“We have a winner,” Lori said in her usual unamused voice.
