The corniest ballbusting story between step-siblings

I konw. This is corny but i wanted to write this story! And i must admit i had a lot of fun writing!



...........................................



It all happened after my 18th birthday. I was watching a movie on the couch with my older step-sister Jane. Since it was still summer i was wearing only a T-shirt and a pair of shorts.

Jane was wearing comfortable as well. A withe baggy tank top wich didn't hide the pink bra underneath, and shorts. We were both barefoot.

The movie wasn't that good. A lame action movie with hot chicks and big boys.
I was soaring when, during one of the fights, the heroine kicked a villan right in the balls. I didn't react at the scene while my step-sister laughed out loud.

"Ahahaha that must be painful!" She had an amused expression on her face. "oh! Ouch! Ahahah" the heroine was now squeezing the balls of the poor villan.

It was pretty annoying seeing Jane laughing at such a corny scene.
"How can you laugh at that? It's not even that painful"

Jane stared at me and raised an eyebrow. She knew very well that i was annoyed by her making fun of men's genitalia. And she was right!

"I think it's funny. Boys are so sensitive down there" she raised her foot and poked me on my cheek with her bigtoe. "it's such a weak spot!" she mocked.

I hate when she act like that. I pushed away her foot. "That's no true. You can't know. You don't have balls!"

"Have someone kicked you in the balls before?" Jane moved again her bare foot on my face.

"Yes! And it's no painful at all! Keep your foot away from me!" I fought against Jane's foot till i got rid of it. I lied! At that time i didn't know how painful a kick in the balls could have been.

"Nah, i don't believe you. I bet if i kick you in the balls you'll be down on your knees in no time"

"I don't think so..."

"Let's try!" she smiled and got up.

"What? Are you crazy? Why should i let you kick me in the balls?"

"Come on! I'm just curious. I've never hit anyone down there. I wanna know how it feels like" Jane paused the movie.

I stared at her for a moment then i closed my legs and said again "No!"

"Ok let's make a bet! I kick you in the balls and if you fall on the floor you'll be my slave for a day, if you manage to stay on your feet i'll be your slave for a day!"

Slave for a day... Jane is an hot girl. Having her as a slave would have been a funny experience. In those days i was desperate to see some real naked boobs, that was a great occasion.

"Ok. But i'll ask you to strip naked when you'll be my slave!" i wanted to be clear with her just in case.

"Oh i know that!" She smirked, lifted her boobs with her hands and let them fall. She was always a step ahead of me, she knew i just wanted to see her breast.

She gestured me to stand up. "Here. Open your legs" i did what she said. It was starting to be a little embarrassing. Jane stared at my crotch and lifted up her foot. She swung her leg back and forward a couple of time "Let me aim" she said to tease me.  She had a thoughtful expression on her face.

"That's no good... I can't kick them if i don't see them"

"What??"

"You heard me. Take off you pants, it's not fair if i miss them"

"oh come on! They are here. Right between my legs..." i had to point at my balls.

"Just your pants. You can keep your underwear on..." Jane giggled. "Please. I swear i'll do anything if you win!"

I thought it was better to play with her rules so she couldn't say anything after my victory.
I sighed and took off my pants.

Jane let out a "Yhea".

Now it was embarrassing! Jane began to swung her foot again an inch from my balls, wich were now protected only by my boxers.

"One.. Two.. Th..."

I closed my legs.

"No! That's no fair" Jane stomped her foot on the floor with a bit of anger.

"Ok, ok, i promise i won't close my legs"

"I don't trust you, close your eyes and hands behind your back"

I did what she wanted. No pants, eyes closed, hands behind my back.

"mmmm, wait a sec"

Now what? I began to be a little annoyed by all her demands. I opened my eyes again and Jane did something that left me speechless. She took off her shirt.

I swallowed. I was amazed by the sight of her boobs covered only by a pink bra. I saw them bounce when she moved toward me.

"You won't stare too long" with that Jane used her shirt to blind me. "There you go. Perfect. Now back to business"

Now it was very, very embarrassing. I stond there with no pants and my balls on display. I couldn't see anything but i knew my step-sister was topless. I felt her foot moving near my balls. I was aroused by the situation. A deadly embarrassing erection began to grow between my legs.

And then she kicked me.

Full force, right on target, no protection. I couldn't do anything but fall on the floor and moan in pain. I heard Jane celebrate her victory while i was on the floor holding my aching balls.

"What the fuck....mmmmmm aaahhh"

I took off the blind. Jane was laughing. "I told you! It's painful! Isn't it, slave?" She helped me on my feet.

"It's not funny. It's a lot of pain oohhh" i was bended over with my hands still on my balls. I looked up at my step-sister. My gaze stopped on her bra.

"You know what that means right? Weak boy... Weak slave boy... Slave of a superior girl!"

Jane puffed her chest to emphasize her womanhood.

"I hate you Jane" I didn't mean it but she was really pissing me off with all that "Slave" and her mocks.

In the end she wanted to see the rest of the movie but i had to lay on the floor with her feet on my face... She didn't allow me to wear my pants and, to increase my discomfort, she didn't put on her shirt. She flaunted her boobs like a symbol of power while my balls were the symbol of my enslavement. She said that.

I had to be her slave for the next day, until evening time. Maybe one day i'll tell you what happened on my slavery day. I swear i was the most embarrassing and painful day of my life.
