Title: Self-Defense Practice (F/m ball-busting) Chapter 1
By: Caligula
Synopsis: Girlfriend practices disabling boyfriend thru nut-crunching!

START STORY:

Jeff sat alone on the sofa wearing his sweat pants and T-shirt, 
watching television.  His girlfriend, Amy, was just coming in the door 
from her self-defense class.

"Hi, babe!" Jeff called with a smile.

"Hi, honey," smiled back Amy.

She plopped down next to him on the sofa and they embraced. She seemed 
in a depressed mood.

"What's wrong, Amy?"

"I just don't think I'm getting the hang of this self-defense stuff. Me 
and the other women just can't tell if what we're doing is effective or 
not?"

"Whaddaya mean?"

"Well, the guy we use to practice on has all this padding, so we can't 
tell if our blows are effective. All we have to go on is the 
instructors assurances that what we're doing can incapacitate a man."

"That's too bad, hon. I wish there was some way I could help." Jeff 
went back to watching television. Amy bit her lower lip while she 
thought about what to say to Jeff. She had hit upon the idea on her 
drive home and was uncertain as to how to proceed.

"Well, there is a way you could help..."

"What...huh? Did you say something, babe?"

"I said...there IS a way you could help me."

"Sure, doll, anything you want." Jeff really wanted to get back to 
watching television so he figured what the heck.

"I'd like to ask you something."

"Sure Amy, go ahead."

"Well.....I was wondering if I could practice some of my moves on 
you...to see how they work on an unprotected man."

Jeff was sort of amused by this. Did she really think anything she 
could do would hurt a grown man? 
"Sure thing, Amy," he said with a chuckle.

"First, I want to knee you in the nuts!" She said excitedly while 
pulling him to his feet.

Jeff hadn't expected this and immediately lost his smile. This WOULD 
hurt!

"Amy, I can't let you hit me THERE!"

Amy began to pout. "Don't you LOVE me? How can I protect myself from 
nasty men if I'm not sure if my techniques work?"

"But Amy..."

"You DO love me...don't you?"

Jeff sighed and swallowed visibly. "Well....." 

"GREAT!!! Now come stand over here and spread your legs slightly." She 
dragged him over to stand in the middle of the room and had him assume 
a spread-leg position in front of her. She reached her dainty hand 
between his legs and felt around for his balls. Once she found them she 
patted them lightly and smiled at Jeff. "There they are. I want to make 
sure I get your nuts dead on so I can see your reaction. Now look me in 
the eyes so you don't see my knee coming, otherwise you might try to 
protect your nads." 

Jeff looked her in the eyes and noticed she had a happy sparkle there. 
How could he deny her anything? Here she was about to bust his balls 
and yet she had the happiest expression on her face he had ever seen.

Amy thought she would tease him a bit first. "Have you ever been kneed 
in the balls before, Jeff?"

"Uh...yeah," he said, a bit embarrassed.

"Tell me about it sweetie." She proceeded to rub his cock through his 
sweatpants and he started to get hard.

"I was about 15 years old the first time, and my sister and I were play 
fighting. She didn't like the fact that I was roughing her up and she 
kept telling me I'd be sorry." Amy stopped rubbing his cock, now that 
it was hard and out of the way of his precious gems. She now had a 
clear shot. "Well...I didn't stop and kept pushing her. She fell onto 
her back, and I went to stand over her. Next thing I knew, she had 
thrust her bare foot up into my balls and yelled 'CRUNCH'!"

"Mmmmmmm," said Amy seductively, "your own sister kicked your nuts?" 
Amy was enjoying this more than she thought!

"Yeah, and then I fell down and grabbed myself and cried for a long
time."

"And she yelled 'crunch'? Why was that?" Amy chuckled at Jeff's 
embarrassment.

"I uh...she used to use that phrase every time she talked about kicking 
a guy in the groin. She used to chase me around the house after that 
kicking her leg towards my jewels and yelling 'crunch'."

"Now before I knee your nuts, I want you to tell me that you love me!"

Jeff swallowed and started to speak. "I lov......."

Amy didn't wait for him to finish. She swung her leg back and swiftly 
brought her knee up into his ballsack. At the same instant she yelled, 
"CRUNCH!!!" She watched to see Jeff's reaction.

Jeff was shocked by the blow, since he hadn't expected her knee to come 
yet. He started to crumple from the pain but tried to remain standing. 
He didn't want Amy to think he was a wimp who couldn't handle the pain. 
It worked to his disadvantage.

"Shoot...I must have missed them!"

Jeff opened his mouth to tell her she was wrong but didn't get the 
chance.

"Don't worry, Jeff. I'll crush those nuts this time!"

She gripped him by the shoulders again and brought her knee up even 
more forcefully, yelling "CRUNCH" twice as loud as before.

This time Jeff gave in to the unbearable agony and slid noiselessly to 
the ground, holding his crotch.

Amy talked to him as he lay there, whimpering in a high-pitched voice. 
"So it takes two hits to the balls to make a man fall down. We'll have 
to try it again to make sure. But first I want to try a kick to the 
balls with my foot. I wonder, Jeff, should I kick you barefoot? 
NO...I'll put my high heels on. If I ever get attacked I'll be wearing 
my heels more than likely anyway."

Amy ran to the bedroom and came out wearing her sexy heels. Jeff had 
managed to get to his knees.

"Ready lover?" asked Amy.

Jeff shook his head. "I don't think I can," he said. She smiled, 
thinking his voice sounded a little closer to soprano than it had a few 
minutes ago.

"But honey," she began to pout, "don't you love me?" She smiled warmly 
at him.

Jeff couldn't resist. "Okay, Amy. But just once more for today, 
alright?"

Amy agreed. She had Jeff stand in front of her again, but this time 
blindfolded him so he wouldn't see her foot coming. "This is my 
favorite move, Jeff. I love all the groin shots but the front kick to 
the nuts is my favorite! My teacher says I'm REALLY good at this one. 
She calls me the 'ball-buster'. Isn't that funny? I guess we'll see if 
I live up to that, huh?"

She took a step back. Jeff heard her heels clack on the floor and 
started to shiver. She slowly raised her foot between his legs and felt 
around for his balls with the point of her shoe. Jeff jumped at her 
touch. 

"I haven't done anything yet, silly." She giggled. "Just want to find 
your eggs, dear. Then I'm going to scramble them!" 

She lowered her leg back down to the floor and eyed his balls 
possessively. She was going to enjoy this! Then suddenly, with all the 
force she could muster, she swung her leg forward and kicked him square 
in the left nut with the point of her shoe. He dropped like a rock, 
yelling like a dying elephant. 

Amy just smiled down at him and laughed. "You look so funny down there, 
Jeff! Did Amy bust your balls?"

 She laughed again. She was struck by a sudden thought. There was one 
more move she could practice while he was incapacitated. She reached 
down and grabbed his ankles. She lifted them up and spread his legs, 
leaving him vulnerable. She kicked off her heels and raised one bare 
foot over his balls. Then with sudden fury, she slammed her bare heel 
into his nuts and started grinding away. She laughed at his cries for 
mercy and finally let him alone. She went and showered, leaving Jeff to 
fend for himself on the floor. 

After awhile, a long while, Jeff managed to get to his feet and heard 
Amy coming out of the bathroom. He saw her bending over, trying to 
select something to wear from her bureau drawer. He quietly limped up 
behind her, to give her a hug and let her know he was alright. He 
reached out his arm and put it on her shoulder.

"Amy..."

Amy grabbed his arm and spun around. "YER GONNA BE WEARIN YER BALLS FOR 
EARRINGS NUMNUTS!!!!!" And then she proceeded to knee his balls once 
again. She clapped and said, "You're really great letting me practice 
on you like that. Good thinking, trying a sneak attack like that!" She 
kneeled down and kissed Jeff on the cheek as he let out a high-pitched 
wail.

"I can't wait to tell the girls at class about this!  Maybe you can go 
to class with me and we can ALL practice on you! You know, my Mom 
wanted me to teach her some of this stuff!  She'd like to take a swing 
at your nuts!" She laughed. "Hey...maybe I could get some pointers from 
your sister! Let me get dressed, and then we can play some more, lover.  
I have this great move called hit-twist-pull, or something like 
that....."
