Teaching my Sister

My kids sister all of 12, came home from school one day looking like she had just been in a fight! Bruises on her arms legs, her hair a mess with leaves and sticks in it.

Karen what happened to you? Did you have a fight with one of your girlfriends?

No it was a boy! Terry Thompson a big bully at school! I hate him and I told him so. He started pulling my hair. So I punched him in the stomach. But he's a lot bigger and stronger than me! I hate him! I hate him! He beat me up in front of my friends and said the next time he was going to make me suck his dick!

Suck his dick!!! Now I was getting mad!

Yeah he took it out and wiggled it at me when I was on the ground. It started getting real big like I've seen yours sometimes when you're asleep.

Ok Karen go get cleaned up and I'll show you a few things you can do before Mom and Dad get home ok. I'll teach you a few things about guys!

A few minutes later my sister was looking a lot better, her long blond hair was back in her standard ponytale, and the redness in her face was gone. She was tall and slim for her age with very long legs emphasized by the tight short shorts she was growing out of! There was just a hint of her budding breast and nipples stretching the fabric of her whiteT-shirt. I could feel my cock stir and my balls pull up at the site of her and what I was about to teach her about how vulnerable us males are.

Ok Karen are you ready for your first lesson in male anatomy. How you can win any fight with a guy no matter how big or strong he is!

"Yes Yes I want to know shown me Billy".

Ok but I've got to take my shorts off to show you ok Karen?

Yea hurry Billy I want to learn so the next time that that Terry Thompson he'll be sorry he fooled with me!

I slipped my shorts down revealing a big bulging package in my jockeys straining for release! Than watching Karens eyes I pulled them out and down releasing my thick heavy cock. It Jolted up to its full eight inches throbbing as my magnificent low hanging balls dangled under between my thighs!

Karens eyes were like saucers a shocked expression on her face!

"Oh God Bill your big! Really big". I've seen pictures of guys balls in sex-ed! But they were little tight things, yours are a lot bigger and really hang down low!

I stood a little straighter at my sisters comments. Reaching down between my legs I lifted my balls up for her.

Karen see these things! These are my testicles you can use them to control or to beat any male regardless of his age or size! Do you want me to show you how?

My little sister just stood shocked looking at my balls!

I lifted my cock up with my other hand pressing it against my belly. Saying don't be afraid Karen!

Here take them in your hands feel them. Get used to handling a man! This is how you can learn how easy it is to control a male!

Dropping my balls! I watched my sister step forward nervously.

Towering over her! She reached between my legs grasping my balls. Her small hands weighing and feeling them!

We were both getting comfortable with the situation now and her curiosity was starting to expressed its self.

These are so big and soft Billy! Are all men like this?

All I said!! If you got a man by the balls you own him! If you squeeze or hit them you will incapacitate him! I'll show you how to do it! Ok Karen?

Ok there's a couple easy ways to do it ok!

First let go of my balls and leave them hanging between my thighs. Then step back. You can either bring your knee or foot up into them hard! But make sure you catch them, this is what takes practice!

But the big thing to remember is to catch a guy off guard. Like pretend your a sexy like full grown Woman.

My sister started giggling! Oh I can do that Billy watch!

Oh I'm so sexy! Billy look at my little nipples aren't their standing out see!!! See Billy!! I want a big strong man like you! Billy!

Pulling her T-shirt over her head. Her little nipples were standing out. My cock responded in kind rearing to its full stature straining up before her!

Looking at it! She emphasized her play acting by slowly wiggling out of her shorts!

Now we were both naked!

My little sister learning fast said.

I want you to be my first Billy! My first big cock! Can you do that Billy? Be the first one Billy to take me?

I moved towards her saying! God Karen I'll be gentle with you don't worry! I won't hurt you!

Suddenly her little knee came up between my legs with such devastating force it dropped me to the floor in a ball of pain!

She was shocked at how easily she had dropped me!

Oh God Billy I'm sorry Billy! Are you ok? Billy are you ok? I didn't know how hard to knee you ok! Are you all right Billy?

She had caught me squarely in the balls! Her sharp little knee driving my balls up against my pelvis bone smashing them! I was suer she had ruptured one or both! But I took the pain my little sister had just delivered and slowly I recovered.

Are you ok Billy? I didn't means to hurt you so bad Billy! But I see what you're talking about! About balls and everything. About a guy being so weak down their are you ok?

Looking up at my little sister! "God she had hurt me." I slowly rolled over and got up on all fours catching my breath. My big swollen dangling testicles hanging between my thighs exposed to her. Suddenly I felt her little hand grasping them!

"Billy teach me more." I want to know everything about these things! Like how hard can I squeeze them? Could I crush them? I've heard about castrating animals and stuff. Do humans get castrated? Like could I castrate you if I wanted to Billy?

Could she castrate me!! Of course she could! In the position I was in right now! She was bubbling over with excitement at her newfound power!

"Yes Yes Karen you could castrate me if you wanted too." You've got me by the balls so you can do anything you want with me!

Wow Billy I could actually cut your balls off if I wanted too?//

Yeah Karen but let go of me now! I was just showing you what you're capable of as a girl compared to a boy or man! So let go of my balls Karen!

"You didn't say please with sugar on top Billy."

She squeezed!!!! I screamed please Karen with sugar on top!!!! Please let go of my balls Karen!

Suddenly we heard the garage door going up!

It was are mother coming home! Karen let go of my balls slapping them hard!! Saying Billy better get your clothes back on. What's mom going to think! "Hurry up you shit." Or I'll kick you in your balls again!!! Hurry!

This was a little shocking! My little sister now ordering me around all of a sudden. But I scrambled trying to get dressed as ordered. Trying to wish my huge hardon down! Panicing I grabbed my clothes and ran up to my room!

Later that evening Karen came into my room! Wearing her pantie and her little training bra!

Like I'ed seen her a hundred times before! But now she seemed different. More grown-up somehow with an air of confidences.

Billy shown me more like earlier!!! I want to learn everything! Show me your self again Billy! I want to handled your balls again like earlier.

No Karen!!!! I made a mistake!! I should of never had shown you that stuff! You're too young to understand about that stuff! So get out of here!!!

I hurt you earlier!!! I can do it again if I want to Billy!

Karen I'm not kidding! If you don't leave I'll make you!

Ok make me! Big brother!

No mom will hear Karen!! So leave!

Then to my surprise my mother stepped into the doorway saying.

Well Well Bill!!!!! Karen's told me all about your little teaching lesson earlier today Bill. So why don't you show me what she's learned Bill.

I was shocked at suddenly seeing my mother standing behind my little sister with an open robe! Her large breasts hanging out, one hand resting on her hip!

My cock strained out tenting my jockeys to Karen's delight!!! See Mom! See!!

I see honey!! Just like his father before I cut his balls off!!!!

Take your underwear off and show me and your sister what you've got for us son! It's time for you to be the student Bill...

I hesitated and my mother nodded to my sister. Who crossed the room and yanked down my jockeys setting free my cock and balls!

"Well Well hasn't he grown into a big boy." Karen!

Pushing my cock down and trying to cover my balls before my mother and sisters eyes! Causing nothing but gleefull ridicule from both!

Be a man for your sister! Mom said! Show her what you've got honey! Better yet show me what you showed your sister earlier today big guy! Teach me how to bust a males balls!

Sliding the robe off her shoulders! Now completely naked save for her high heels. She approach me ordering my sister to pull my hands away from my cock and balls. Saying here Karen baby I'll show you something!

See those big dangling testicles hanging their? You've got to think about them as big ripe male fruit ready for the picking, ready for the squeezing!

"Oh God Mom don't Mom." Please mom!!!! I was just trying to teach Karen how to defend herself!

Karen honey why do you think your brothers dick is big and hard like this? Its because he can't control himself! Look at it! It's rampant! If he had the chance he'd try to stick it in me or you! So what do we girls do to control a rampant cock? Weeeeeeee do thissssssssss!!!!!!! We grab the bull by the balls and we pull down and twisssssttttttt!!!!!!!

My knees buckled under me!!!! But my mother held tight to my balls keeping me from totally collapsing to the floor! The weight of my body falling and the strength of my mothers grip stretched my ball sack almost two feet from my groin!

I could hear my sister screaming!!! "No Mom you're going to the rip his balls off." "Don't Mom don't rip his balls off." He didn't touch me with his dick or anything Mom! Leave go of his balls Mom!!!

Finally my ass hit the floor!!! My balls flopped down with a thud outside my thighs than there was blackness!

Dreaming I was dreaming. I could feel cool water and hands moving my testicles around lifting, gently stroking they felt so good being handled. Looking down between my legs my eyes trying to focus. I think my sister was their but my cock was in the way standing straight up! My hand fumbled down moving it to one side, it was my sister..

Karen what are you doing? Karen wears Mom Karen? What are you doing down their Karen?

Mom said to shave all your hair off your ball sack Billy! They really look big without hair on them see!!!! Big and smooth!

Why are you doing that Karen?

Because Mom says she doesn't want you to get infected after she cuts your balls off! She says it's time for you to be castrated and she's going to let me help!

She says sooner or later you're going to try to stick that big cock of yours in me! She says that after she cuts your balls off you'll be safe around me! Billy I liked seeing you all big and hard like that is that wrong?

Oh God Karen!!!!!! Take it in your little hands and start pumping up and down on it before Mom gets in here please Karen!!! She's right Karen I have been thinking about trying to fuck you with it, at nights sometimes I jerkoff thinking about you and how it would be your first time! The first time with your brothers big cock in you!

"Oh God Billy me too." I've had the same feelings about me climbing on top of you taking your thing inside me! "God I want it in me Billy."

Hurry Karen get on top of me! Take me before Mom gets back!

The next day Karen told Mom she was to sick to go to school, not feeling well she said. But in reality she was having trouble walking. I too was having trouble walking but for a different reason!

A month later my sister giddy with excitement burst into my room wearing big gold plated ball ear rings!

The End
