Rebecca was a college student. She had a petite build, but she was considered very attractive by the boys at her school, which were plenty, since she was in an engineering school. Boys being boys, pumped up with masculinity and testosterone, were always ogling at the girls in the school, which were not many.
But Rebecca was the popular girl that stood out. She had this kind and gentle demeanor and she was good at everything. Her grades were great that she always appeared in the dean’s list. She was also the captain of the self defense club in school, which were joined by many of the girls in school, given her black belt in martial arts.
Rebecca was used to boys asking for her out, but she never felt anything for them. She also had encounters with catcalling and harassment sometimes, but most of the boys knew not to mess with her.
She became the captain of the self defense club because she was frequently bullied by the opposite gender in high school, given her small sized build. Her parents started sending her to martial arts school, which she got pretty good at, and slowly earned each of her belts. She decided to be the captain of the self defense team to teach anyone who was interested to defend themselves so that they would not experience the same trauma as her.
Every year, a group of new freshmen would join the club. Before that, there would be a club exhibition where freshmen can come in and ask questions to find out more about the club, before they would indicate their interest to join.
Rebecca, with a group of her club friends, painstakingly planned over the course of a few weeks, how to hit their quota of at least 50 new members this year.
“We definitely need boys to join”, one of her friends Brenda suggested, since there was no way they could hit 50 new members without getting new boys. Getting 50 girls was extremely difficult, since the gender ratio of her school was severely skewed towards males.
“Hmm, how can we do that…”, Rebecca wondered. She was a bit discouraged as her self defense club focuses a big part of training on self defense against male attackers. “Surely no boys would want to come to our training…” Rebecca mumbled in disappointment. Brenda nodded in agreement, stifling a giggle as she knew how much a boy would suffer in this club.
Brenda then said, “Okay, how about we change the way we promote the club? Let’s completely not talk about our techniques against the boys. We should just frame it as a welcoming club for all genders, and talk about other self defense techniques like simple defensive fighting moves, against knives, guns and things like that. Absolutely no kicking anyone’s nuts whatsoever.”
Rebecca’s eyes lit up. She knew this was a brilliant idea, since being a girls dominant club, there would definitely be many eyes on their club. Many boys would love to join, they should not scare them off by the idea of threatening their family jewels.
She hesitated that it would be akin to lying to the new joiners, but since her portfolio and performance as the club leader depended on this recruitment event, she gave the go-ahead.
A week later…
The recruitment day was here. Rebecca woke up early, washed up and tied up her hair, wearing a light blue dress and tied her black belt around her waist. She sprayed a little bit of perfume. She looked very confident in the mirror.
“Today’s the big day”, she thought. Deep inside, she was hoping to see some of the hot new guys joining the school, and even better to join her club. Because of her bullying trauma in her early childhood, she always shunned away from boys and avoided them. She always hoped to find the right one that could understand her, not just be there for her looks.
And well to her expectations, there were a ton of cute guys who visited her recruitment booth in the school. She had severe anxiety from talking to boys, so she let Brenda and her other friends mend the booth and run the show.
“Hi, are you from this club?” Ryan asked shyly. Rebecca, who was camped at the back of the booth away from the crowd, turned around in surprise. “Damn it! I am so nervous to talk to anyone!”, Rebecca thought.
She turned around shyly and saw Ryan. She was star struck. Ryan was a very muscular and good looking boy. He was tanned was a foot taller than her. “H.. Hey”, she replied, blushing.
Ryan was a freshmen who just visited the school for the first time, for recruitment day. He was told that students could take a look at the clubs around the school and pick one to join, with a promise of a ‘vibrant student life’. But honestly, all he wanted was to look at the girls and pick up one.
He had heard how notoriously bad the gender ratio in this school was, but this school was the only one that offered the course that he wanted. So, he decided that he would use up every opportunity to talk to girls. And he saw Rebecca right there at the corner of his eye, at the back of the booth and thought that she was cute. So he went up to her. Plus, he had boxing classes during his free time, so a self defense club? Perfect for him to show off his skills.
“You are cute, what is this club?”, Ryan said. Rebecca stammered, “Uh.. oh. Thanks.”, at a lost of words. She was amazed at how handsome he was, with a bright smile and nice eyes. “It’s a self defense club, we teach people how to defend themselves against anyone”, she replied.
“Ohh, that sounds easy, I am pretty good at boxing myself”, Ryan boasted proudly. Rebecca almost wanted to roll her eyes. Internally, she was holding back her laugh thinking of how fast Ryan would be taken down by her, with a hard fast knee to his gonads.
“Uhh, its quite different”, she replied. “You wouldn’t last…”, she halted herself, remembering that she had to RECRUIT new people, not scare them away. “You wouldn’t think that it would be the same once you experience it”, she said, smiling.
“Ooo, interesting”, Ryan remarked. “That’s gotta be bullshit, I think I know everything about fighting already”. Admittedly, standing right in front of Rebecca, he thought she was even cuter at a closer distance. But what can a small girl like her do?
“No you don’t. I am the captain of the club, you can come to a trial session if you’d like. I will personally be there”, Rebecca said, slightly annoyed but already used to the brimming over-confidence by now. She had seen how many boys had that same smug look on their faces, but after every single sparring session with her, they changed their minds immediately after.
“Sure, I could do it now, since I am free”, Ryan said.
Rebecca then brought him to their training room just a stone’s throw away, in the next block of the school. “I did not expect you to be the captain. You don’t look like one”, Ryan said while they were walking.
“I am. I have a black belt in martial arts. I have been quite active in the club since I joined the school”, Rebecca replied.
“Ahh, I see.” Ryan chuckled. A black belt? That small girl couldn’t do anything to me. He had sparred with some of his black belt friends in the past, it was a walk in the park.
In the training room…
“Okay we are here”, Rebecca said. Rebecca led Ryan into this massive room. It was their sparring room that the club frequently used. It had no windows and was relatively soundproof. Thanks to that any passerby would not be able to see the heaps of males clutching their aching balls, collapsed the floor during training sessions. Or hear their screams of pain from taking a beating.
“Great, this a nice place”, Ryan said, putting his backpack aside and took off his shirt and thin gym shorts. He put on his hand wrap that he used for boxing. Probably wasn’t going to need it anyway, he thought.
Ryan put his hands on the back of his neck, flexing a little bit of his muscles to Rebecca. He was quite ripped, and was proud of his body. He knew many girls would fall for his looks, and was sure Rebecca will too. He looked at Rebecca with a smile, in his tight yellow boxer briefs, which hugged his huge bulge.

Rebecca stared in awe. She thought Ryan looked absolutely stunning. She did not ask him to remove his clothes, but was secretly happy he did. She couldn’t help but peer down at rock hard abs and then his bulging tight yellow boxer briefs.
She started getting slightly aroused as she thought the boy in front of her was so hot. But just a tad over-confident, as she decided to bring him down in just mere seconds of the fight.
Rebecca started off by taking a massive swing to the side of Ryan’s head, to which Ryan blocked it with his arms. “Easy”, he thought, but winced slightly at the impact. She was stronger than she looked. He had to spread his legs and stand in a more stable stance to maintain his balance.
Ryan also stole a glance at Rebecca’s panties, as her short skirt struggled to cover her when she swung her sexy legs. He felt his boner starting to grow.

Seeing that Ryan was visibly distracted, Rebecca decided to end the fight right there and right now. She knew exactly what she wanted to do and let out a sly smile. His legs were right open, exposing the prime target – his testicles.
Rebecca always knew that testicle kicks were the solution to any male aggression. Since young, she had mastered the skill of various ways of striking the male body part. Knees, kicks, punches, grabs, whatever. She knew it like the back of her hand.
However, there was one technique that was the sure way to bring any boy down. It always worked and had never failed her. She decided that she wanted to bring that out, to show Ryan what the self defense club was really capable of.
She faced away from Ryan, confusing him about her next attack. “What, was she going to run and give up?”, Ryan thought, his hands still on guard.
But in a split second, she spun around, and swung her smooth legs upwards in one swift motion, between Ryan’s thick muscular legs. It was hard to miss. His package stood out in his yellow boxer briefs, which was a foolish choice against Rebecca, since she aimed directly beneath the outline of his nutsack and kicked them into his pelvis with a loud thud. She felt his two rocks trapped against her feet.
Rebecca was too nimble for Ryan. He helplessly waited for the impact and felt the all too familiar dreadful pain shooting into his balls.
Rebecca was getting wet with excitement. She looked directly into Ryan’s eyes after the impact. She always loved seeing their expressions change as they process the excruciating pain that slowly came to them.

Morever, it wasn’t over. In that split second, Rebecca, while maintaining an upward force and grip on the back of Ryan’s scrotum, pulled her feet backwards toward herself forcefully, executing the ultimate finisher – testicle scoop kick.
She could feel Ryan’s testicles being ripped away from his body as her feet slid across sharply towards her between his legs like sandpaper, tugging his testes towards her with a lot of force. She knew it had worked perfectly. The outline below his penis showed his right testicle in a horizontal oval shape, instead of the usual upright shape. He was also hard, leaving his shaft out of the way which was what Rebecca had hoped for.

The testicle scoop kick was something she had experimented for a long time, and proved to be the most effective because it not only consisted of the initial impact to the testes, but also a second maneuver which involved a sudden pulling action. If a male was still standing after the initial kick, he would be on the floor after the ‘scoop’. It was said to be the most painful self defense technique against any man.
Ryan screamed in pain and gripped his nuts, wondering if they were still there. It felt like his nuts was castrated and ripped away by Rebecca’s feet. He had been kicked in the nuts before, but never this painful. It was a very very sharp pain, especially after Rebecca performed the ‘scoop’, as Ryan watched helplessly. It was no ordinary kick. She did something different. His legs started to give way, when Rebecca gave a flying kick to his face.
The impact of her kick knocked him over, leaving him on the floor and out of action. She could play with Ryan a little longer before knocking him out, but she had to go back to her recruitment booth.
It was quite a funny sight as his hands were still covering his ballsack, leaving his face unprotected. Rebecca looked down with a satisfying smile. She pumped her fists in the air in victory as she stomped her right foot down on Ryan’s face.
Ryan helplessly saw Rebecca’s foot smashing down, and catching a glimpse of her now dripping wet panties before everything went dark.

Back at the recruitment fair…
“Hey, where did you go? We need more manpower here”, Brenda asked when Rebecca returned, unusually sweaty and glowing with confidence. “Oh, I was just sparring with a freshmen, he wanted to experience the techniques we teach”, Rebecca replied, as she winked. Brenda laughed.
Rebecca settled down to start promoting her club again. A boy came up to ask her, “Hi I am interested can I join?”.
Rebecca smiled as she handed him a clipboard to fill in the application form.
