The best sister in the world. Part 4

That year Max was super excited for the summer break. He gonna spend a week at his parents' summer house with his mum, his aunt and his lovely big sister Lola. It happened every years but that time Max knew that Lola liked to hit him in the balls. He gonna spend a lot of time hanging around with Lola and they even gonna share the bedroom. He knew there will be a lot of occasions to have his balls busted.

It was a long trip to the summer house, almost three hours with the car. Max planned something to make the journey a little more exciting. He opened a little hole inside the pocket of his shorts. Then he tied a shoelace around his balls and put on his underwear and the shorts. It was a bit tricky but he managed to pass the shoelace through the hole he made in his pocket.

With his balls leashed he sat next to Lola in the back seat of the car. Lola was already sat in the watching her phone. Mum Samantha and aunt Jenny loaded the last few things in the car and sat in the front seats. The trip to the summer house began.

After about twenty minutes of driving Samantha and Jenny were chatting together and Lola was looking out the window. Max took the shoelace out of his pocket. "Lola..." he swallowed. "I've found this shoelace on the floor... is that yours?" He wanted Lola to tug on the shoelace and maybe hold it for the rest of the trip.

Lola turned to her brother and took the shoelace in her hand. She tried to pull it out of Max's pocket but the shoelace didn't moved all the way out. Max winced when he felt his balls pulled by the string. He covered his crotch with his hand. Lola tugged again on the shoelace wondering why it didn't came out of the pocked. "Did you tied it around your balls?" She exclaimed innocently, just for fun. "It' s not mine, weirdo" she said letting the string fall on the seat.

Spotted! Max's plan was a total disaster. He suddenly realized he didn't have a reason for the shoelace to be stucked inside the pocket. He grabbed the shoelace and put it back in his pocket pretending nothing was happened. Luckily for him Samantha and Jenny didn't pay attention to what was happening in the back seats and he was sure that Lola was joking when she said he had the shoelace tied around his balls. But still it was too risky to go on with the game.

After the first hour of driving Max felt sleepy. He closed his eyes to take a nap. Lucky for him a little of the shoelace was poking out the pocket.
Lola noticed the lace and couldn't help but thought about what happened earlier.
It was really strange that, out of nowhere, Max asked her about the shoelace. Besides that why it was stucked inside Max's pocket?

Unlike her brother Lola was a smart girl. It didn't take long for her to figured out what Max did with the shoelace. Max had tied the string around his balls and wanted Lola to pull the string in order to hurt his balls. She olny had to try and pull the string.

She took the shoelace and gently tug at it. Max felt something pulling his balls and opened his eyes. His heart began to run when he saw Lola with the string in her hand. She was smiling.

Max covered his crotch with his hands and pretended to sleep again. Lola pulled the string again and noticed how Max expression changed a little in a grimace. Lola understood she was right. The string was tied around Max's balls.

She thought that after all Max had a funny idea with the sting. If he wanted to have his balls tortured then why not torture them. She began to play with the shoelace pretending she didn't know what she was doing.

Max was in heaven. The pain in his balls was increasing with every tugs and the sensation of having his sister holding his balls by a leash was amazing. He wanted Lola to pull the string even stronger but he couldn't ask for that he could only hope in hia sister.

Lola was loving what was happening. She kept on toying with the string pulling it from time to time. Max didn't pretend to sleep anymore. He kept his head turned to the window to hide his expression of pain from Lola.

They were almost twenty minutes from the summer house and Lola decided to gave Max some rest from the torture. She left the shoelace and after a while Max put it back in his pocket. He was more than satisfied by the long trip and the torture his sister "unconsciously" inflicted to him.

When finally they arrived at the summer house it was evening. Max setted his stuffs in the bedroom while Lola did the same and decided to have a shower before dinner. When he stepped in the bedroom wearing only a towel around his waist Lola wasn't there anymore.

Max thought he had lost an occasion but then something came in his mind. He let the towel fall on the floor and stond there naked. He wanted to be caught naked by his sister!

Lola gasped when she saw Max with nothing on. "Max we're going out for dinner." She said and acted like she didn't care about her brother nakedness. She wanted him to know it was a ok with her if he wanted to saty naked in the bedroom. "I'm gonna have a shower as well" Lola took her shampoo from her bag. "I don't wanna be late for the dinner. When i came back i want to see you ready!" She said and headed to the bathroom.

Max was a bit surprised Lola didn't say anything about his state. He expected her to say something like "when i saw your balls i kick them" like she did the last time but unfortunately nothing happened. He decided to try again. Still naked he laid down on his bed. Legs open and his balls on display. He took his phone and began to play some silly video game. It was only a matter of time before Lola caught him naked again and not ready for the dinner. Max was sure she gonna get mad to him.

Lola was sure Max won't be ready for the dinner. Actually she began to enjoy being the mistress of her brother. She put on bra and panties and wrapped a towel around her chest. As she expected Max was still naked when she stepped in the bedroom. She tought It was really funny how he was laying on the bed with his balls ready to be kicked. Max acted like he didn't see her coming. Lola lost no time. She quickly walked to Max and "SMACK" she punched him in the balls. Max yelled in pain. He covered his balls and rolled over the bed. That was a pretty hard punch. Lola took off the towel and searched for something nice to wear. "That's what happen when i tell you to get ready and you don't!" She exclaimed putting on a pair of shorts.

Max was now more than satisfied by what he gained. He sat on the bed and moved his hands from his crotch. For a moment he turned to Lola and couldn't help but noticing she wasn't wearing a top. He found her really sexy. Her boobs were bigger than he thought.

Lola noticed how Max was staring at her. She turned to him with her hands on her hips. The situation was arousing her. She let Max have a good look at her breast then she stepped in front of him and grabbed his balls. "If you don't get dress i'll pop them!" She said squeezing Max's balls harder and harder.

"Ok ok..." Max managed to say trying his best to not scream. He didn't want his mum and aunt to know he was in pain.
Lola twisted her wrist adding more pain on her brother's balls. She enjoyed his gaze fixated on her cleavage and noticed a bit of pre-cum on the tip of his boner.

It was like she was about to squeeze the cum out of his balls. Max grabbed her wrist. It began to feel a little to painful. Lola pulled his twisted and squeezed balls away from his body forcing him to stand up. Max moaned and began to trembling. "Now dress up or we gonna be late" Lola let go his balls. "I don't wanna tell you anymore" she added slapping Max hard penis. "Oooh sorry sis..." Max took a second to recover and began to dress up.

He looked again at Lola. She was a sexy girl and a great ballbuster. He was lucky to have a sister like her. He wanted to hug her and say thank you for the squeezing but he couldn't.

Now he was sure. That gonna be a great week of ballbusting!
