The best sister in the world! Part 3

Sam was cheerfully wagging his tail. "Who is the cutest doggy? Who is the cutest doggy? You're the cutest!" Lola playfully petted the dog. Sam rolled over on his back and offered his belly to Lola. "Do you want me tu rub your belly? Here we go!" She rubbed his belly, Sam was breathing fast with his tongue out of his mouth.

Lola loved her cutie labrador puppy. When she was in the garden Sam was always around her. He wanted to play all the time. His favourite toy was the ball. He used to bring the ball to Lola and wait for her to throw it. He was so funny when he barked to get attentions.

It was a sunny saturday. A perfect day for a walk with Sam. Lola took the leash and put on her shoes. Her mum, Samantha, was about to leave as well. "I go out for shopping. Wanna come with me?"
Lola thought about it for a moment but decided to walk Sam.
"I'll go out with Sam. Is Max still out with his friends?" Lola said putting the leash on Sam's collar.
"He is. I told him to be home for dinner."

Lola took her phone and texted Max. "Mum is out for shopping. I walk Sam. Nobody is home. I'll leave you the keys in the same place"

While she was walking with Sam Lola couldn't help but think about Max and his funny behaviour of the last days. After his ballbusting birthday he kept on trying to get his balls busted almost every day. He was always around Lola when she was home, always with his legs apart. But Lola didn't hit him a single time. She found amusing to tease him talking like she was about to kick his balls.

Once he was in his bedroom and called Lola to tell her something. She found him on his bed wearing only his boxer... He was so cute when he acted like that. Lola wanted to have some fun with Max again but she didn't want to do it too often. Only from time to time. She liked to please her lovely little brother with a kick or two in the balls but she couldn't do it every single day.

Her phone buzzed. It was a message from Max. "I'm coming home." It said. Of course he was coming home, thought Lola. He wanted is balls busted and he had a good occasion to spend some time alone with her.
Lola felt butterflies in her belly. She was in the right mood to play with Max. She wondered how Max gonna offer her his balls this time.

When Lola came back home she found the door open. Obviously Max came back to. She left Sam in the garden and went into her room. She knew it was just a matter of time and Max will eventually show himself with his balls on display.

She noticed the her bedroom's door was open and the light was on. She stepped in and Max was there! He was wearing only his boxers and his hair were wet. "Max! What are you doing in my room?" Lola asked pretending to be surprised by the awkward situation. "I was just searching for the hairdryer. Do you have it here?"

Lola was standing on the door with a smirk on her face. Max had found a good excuse to stand half naked before her. Good job little brother. She thought. Time to give Max what he was looking for.

Lola locked the door and put the key in her pocket. "It was reckless from you let me caught you in my bedroom..." she walked towards Max. "...i think i'm gonna keep you in my room for a while. I bet you know what happen to your balls when i find them in my way!"

Max's heart skipped a beat. He finally succeed. He was about to have his balls busted by a girl. And now what should he do? He couldn't simply stand there and let Lola abusing his manhood. He didn't want her to find his "secret".
He covered his groin with his hands "No. Not my balls please!"

"Yes yes, your balls!" Lola grabbed his wrists and moved his hands away from the target. She found amusing how Max didn't even try to stop her.
"Ouch!" She exclaimed before smashing her knee into Max's balls.

Max let out an "oof" and instinctively tried to grab his balls but Lola was still holding his wrists. She hit again, and again for a third time. Max lowered on his knees and Lola let go his wrists. He fell on the floor with his hands on his crotch. He enjoyed the moment. And it wasn't over it was just started.

Lola pushed Max on the floor with her foot and made him roll on his back. She stared at Max. "It's so fun playing with your squishy balls!" She laughed. Max was still covering. Lola decided to be kind and give him an excuse to move his hands. "I won't let you go if you don't let me hit those balls so no more covering!"

Max moved his hands. He was loving his sister for what she was doing. A boner was growing in his boxer but Lola didn't say anything about that. She didn't want to embarrass Max and ruin everything.
Lola took her time to take off her shoes. She wanted to feel his meat crushing under her naked foot. Max was breathing heavily waiting for Lola step on his balls.

Eventually Lola raised her foot and stomped on Max's vulnerable balls. Max groaned in pain, or better in pleasure. Lola kept her foot pressed on his groin. Her poor brother wasn't able to talk in that moment but only moan. "Ouch my poor balls!" Lola mocked him rubbing her hand on her smooth crotch. Then she raised her foot again and stomped for one more time on Max.

The pain was incredible but the only thing he could think in that moment was the pleasure he was feeling. There was a moment of silence. Max looked down at his massive erection and blushed. That was hard to explain without admitting his love for ballbusting. He began to regret the decision to wear only brief.

Lola was staring at Max's boner as well. She knew Max loved to be hit and the reaction of his penis was normal. She noticed how her brother was growing embarrassment about the state of his penis. "Don't be ashamed about that" she said pointing at his penis. "After all it's normal at your age growing an erection when you're half naked with a girl!"

Max felt relieved by her kind words. "I'm sorry but you locked me here and told me to not cover... it's not my fault!" Max began to get up.
Lola giggled hearing that. "Ahah poor little boy at the mercy of his sister!" She said and kicked Max's balls before he could stand on his feet. Max lost his balance and fell foward hitting the floor with his knee.

"Aaahhfffff" Max yelled. He rolled on his back holding his knee. Instinctively he closed his legs to protect his balls. Lola didn't mean to hurt him that bad. It was an incident. Surely she couldn't say anything about his knee after what she did to his balls but she was concerned for him.

"That will teach you to not walk in my room with out permission!" She exclaimed helping him to get up. "Sorry..." Max stared at Lola with his legs firmly closed and his hand on his groin. That was it, he had enough.

Lola opened the door. "Go now... you need to dry your hair..." she was smiled at him. Despite his aching knee Max smiled back to her. His aching balls were everything he had bargained for.

Max was forgetting something. Lola opened her wardrobe and picked her personal hairdryer form a drawer. "Here! You need it, don't you?" She acted like she had fallen into the trick of the missing hairdryer.
Max felt like he was the one in control of the situation. Apparently Lola didn't suspect anything about his ballbusting fetish. She was the perfect sister indeed!
