My sister Nathalie. Ballbusting and foot fetish!

It all happened during an hot summer day. I was home alone and with nothing better to do than take a nap on the couch.

It was the loud sound of a door slamming that woke me up. I opened one eye to see my older sister Nathalie in the living room.

Apparently she had just come back from jogging. She was in athletic clothes.
Running shorts and a tight top.

We didn't exchange a single word but i was kinda pissed by the way she abruptly interrupted my nap.

Nathalie took off her running shoes and sat on the floor to do some stretching.

Still laying on my back i looked at her for a moment with my eyes half-closed then i said it.
"Your feet stink"

To be honest, from my spot on the couch i couldn't even smell her feet. I just wanted to annoy her.

Although we were both old enough to attend college we never stopped teasing us. That was our way to play when we were children. I used to say something bad to her an she used to start a fight or do something mean to me.
Nothing changed.

"They doesn't" She gave me a dirty look.

"Trust me. They smells"

"It's not true! You jerk!" Nathalie took one of her shoes and threw it to me.
I'm quite sure she didn't aim but she hit me right in the balls.

I let out an "ouch" and grabbed my balls. The hit wasn't too painful but she caught me by surprise and i react instinctively.

"Yhea! Did i got them?" Nathalie mocked me with an amused expression for her lucky shoot.

I picked the shoe that she'd thrown me and smelled it. "Puff what a disgusting smell!"

The shoe was smelling for real but not that bad. It made me smile when Nathalie smelled the other shoe to check if i was right.

"They don't stink! Idiot!" again she threw the shoe but this time she aimed for my balls.
This time the hit was a little more painful.
"Yhea two out of two!" Nathalie laughed.

"Ahhmm you did it on purpose. I hate you and your dirty feet"

"Ahahah are you sure?" Nathalie slided on the floor and got closer to me. She raised a foot still covered by her socks and put it right on my face.

"Come on have a good look! Are you sure you don't like my feet? ahahaha"

She rested on her elbows and put both her feet on my face.

I wanted to play a bit i let her rub her feet on my face. I was smiling and she was too. It was as if we were childs again.

"Are they smelling? Uh?"

The smell was a bit stronger on her socks and i couldn't endure the teasing too much.

"I'm sure! I hate stinky dirty feet!" i playfully pushed away her feet.

Nathalie stood up and grabbed one of her shoes. She held the shoe right above my crotch and stared me in the eyes.

"Say it again" she dared me. "say that my feet smell and lets see what happens to your balls" she pretended to be serious but couldn't hide a smile.

I decided to dare her to hit me in the balls. Just to see if she had the guts to hit me there for real.

"Your..."
I looked at the shoe that was menacing aiming at my balls.
"Feet..."
I made pause for suspense.
"Stink!"

Bang! At the word "stink" Nathalie slapped my balls with the sole of her shoe quite hardly.

"ooohhhh" I grabbed my balls that were now aching. "You hurted me!" i pointed out.

"Opsie! Scrambled eggs for dinner!" she mocked me enjoying my state of pain.

"You brat! My balls are on fire" Nathalie laughed at my words.

She was looking at me from above. I was still laying on my back. It looked like none of us wanted to quit our silly game now.

"Oh poor you! Are your dicklet hurting too?" Nathalie smirked.

"it does!" everything between my legs was aching.

As if was something completely normal Natalie sat on the sofa and, still holding the shoe she placed it on my groin.
"You keep on saying my feet smell i keep on hitting! Are my feet smelling?"
She stared at me right in my eyes and raised an eyebrow. She wanted me to say something.

I didn't let out a single word but nodded to say "yes they are".

With a quick motion she hit my balls again. I jolted and groaned. She smiled amused by my reaction as if was playing a funny game.

Now she made herself a bit more comfortable and raised a foot to make me smell it.
Her foot was right under my nose while she was tapping the shoe on my balls.

I was a little scared. My balls were actually hurting but for some reason i didn't want to give up. I wanted to play the part of the tough guy.
"ewhh you should wash them!"

At my words Nathalie made an "o" with her mouth as if she was surprised by my cheeky attitude.

She slowly pressed the shoe down on my balls. More and more making an angry face.

"ouch... That's hurt.... Nath..."

Damn it! She wasn't realizing it but she was flattening my balls.
I grabbed her wrist and begged her to stop.

"Stop it... You're hurting me"

I raised the tone of my voice and Nathalie used her foot to gag me.
"mmmfffmmnnn..."
She pressed my balls a little more then she stopped.

I grabbed my balls and closed my eyes tightly. "Are you crazy? You hurt me for real..."

Nathalie laughed. I couldn't believe it. Maybe she didn't know how much she hurt me.

I laid there to recover a bit while my sister was still giggling and wiggling her toes near my face on purpose.

I must say that, although my balls were on fire, i was glad to see that Nathalie was having fun.

"It's only your fault bro! I told you what would have happened to your balls but still..."

"oh oh my balls are tougher than you thought. Don't worry!"

Nathalie smiled delightfully and took off one of her socks. She made it swing above my nose.
"Does it smell?" she asked in a mocking tone of voice.

"it does!" i answered and covered my nose with an excessively disgusted expression.

Then Nathalie did something weirdo that i didn't expect.

She lifted a bit the waistband of my shorts and shoved her dirty sock inside my underwear. She had an amused expression on her face, as if she were a child who was playing.

"Ewhh that sucks!" i moved my hips in discomfort.

"If my socks smells, then your dicklet will!"
Nathalie pointed out giggling.

Then she took off the other socks, made me smell it and shoved it inside my boxers as well.

"There you are!" Nathalie slapped my balls with her hand. I winced at the touch. "Your dicklet is on a meeting with my socks"

Right in that moment our game was interrupted by mum who had just come back home.

Quickly Nathalie moved away from me. We were both a little embarrassed but lucky for us mum didn't notice anything.
We acted like nothing had happened but i couldn't took off the socks from my underwear since mum was in the room.

We chatted for a while then mum left us alone again.

Nathalie pointed at me. "You're not allowed to remove my socks from your dicklet" She whispered. "or your balls gonna suffer more!"

I looked at her and nodded to say yes.

"After dinner you come in my room and we'll talk more"
