Ballbusting for the Whole Family

 Ballbusting for the Whole Family, by someone

Crammed together in the minivan, Dylan was bored. With nothing to do, he nudged his older sister awake. Dylan and Tiffany were the youngest of the four and were stuck in the backseat.

“What is it?” Tiffany hissed, annoyed at being awoken from her nap. She was a brown-haired, medium height girl at about 5’ 3” that tended to be shyer than her older sister.

“I’m bored”, Dylan whimpered, “I don't know what to do.”

“Let me sleep!”

Dylan of course wouldn't let this happen. He tended to be super athletic and played select baseball, football and basketball, the opposite of his nerdy, older brother, Zak. He continued to nudge and poke Tiffany. Finally fed up, she elbowed him right in his balls. With thin basketball shorts on, there was nothing to protect him.

“OUUUUCCCHHHH”, Dyland yelped, although his brother, sister and mom were sleeping and dad was used to the siblings fighting and didn’t care. “Why would you do that?”

It was actually the first time Tiffany had hit anyone in the balls or even touched a guy anywhere near his manhood. She was friends with some popular girls but didn't hang around guys very much.  

“Knock it off or I’ll do it again.” As Tiffany said this she hoped he did. She thought it was fun. Unluckily for her, Dylan left her alone for the rest of the trip.

When they got to the hotel, Tiffany told her older sister, Megan, what she did to Dylan in the car. Megan laughed and stated she wanted to try it herself.

Later that day, the four kids were left to hang around the hotel as their parents, Aaron and Taylor, went on a date to a fancy restaurant and a movie after to get some alone time. They would be a couple hours and would be bringing food back afterwards for the kids.

“Why don't we go swimming at the pool”, Zak asked.

“I'm down”, Megan answered and that was that. Tiffany and Dylan all got their swimsuits on.

Zak was ready first and waited for the others outside the room. He was about 5’ 7” and was wearing bright orange swimming trunks that came right above his knees.

Megan and  Tiffany were out next. Megan wore a plain black bikini, showing off her tan body and amazing ass and long legs. Tiffany was a little more modest, wearing a blue top and white bottoms.

Last to come out was Dylan, who wore some blue swimming trunks that came to his knees.

They quickly ran to the elevator and went to the bottom floor. Like all siblings, there was some shoving and teasing, and since they all were around the same ages, they had a close relationship. As they walked to the pool, they didn't see anyone else around.

They arrived at the pool, and there was only an older man and women there. The four dived into the pool and eventually the older couple left. They swam around and were constantly horsing around and splashing each other.

Eventually, things calmed down and after an hour everyone was getting bored. Tiffany and Megan stood at the deep end of the pool and were chatting about random stuff.

“Let's go sneak up on them and splash them!”, Dylan laughed.

“Why not? Nothing better to do”, shrugged Zak as he began to swim over to the girls.

Dylan and Zak waded up behind the girls, who were leaning against the wall. On the count of 3, they started splashing with our stopping.

“Ugh stop!”  Megan screeched.

Meghan kicked out and hit Zak right in the balls, she started laughing.

Dylan kept splashing and got a bunch of water into Megan's mouth. She started choking but quickly got over it. She was pissed.

“I'm going to get you for that”, she hissed at him and quickly chased him down as he tried to swim away. She grabbed him tightly and held him still. Although he was more athletic, she had him wrapped up in her arms.

“Come help me, Tiffany!” Megan bellowed. Together they got him out of the pool. “Hold him still. What should I do to him?”

“Hit him in the nuts!”

Dylan began to squirm and attempt to get away, but Tiffany had his arms locked from behind. Eventually, he gave in, curious if she would actually do it.

Zak sat on the side of the pool watching, holding his own sore balls.

“I know what I'll do”, as Megan gave Tiffany a wink. She then went up to Dylan and kicked his feet out, giving her easy access to his balls. She then put her arms on his shoulders. Instantly her knee went straight up into his balls. Once, twice, and then three times. Tiffany was laughing so hard, she dropped Dylan and he lay sprawled on the ground cupping his groin.

Zak sat 15 feet away, in utter awe at what he had just witnessed. Never before had he seen his sisters do anything close to what they had just done. Usually when fighting, they fought fairly. Megan and Tiffany were still laughing, and eventually walked trotted away to sit at a nearby table.

“That was so funny”, Tiffany said in awe. “We should do it again, and to Zak as well!”

“Mom and dad won't be home for a while... so we could bring them up to the room and have some fun!” Megan said this with a slight giggle.

Megan and Tiffany walked over to Dylan, who after 10 minutes was still holding his crotch like his life depended on it. Megan yelled for Zak to come to help bring him upstairs to their room.

Eventually, they reached their room and got inside. They had to split the room since it was only a two-bed room. Their parents had the room next door and it was connected by a door in between.

They laid Dylan down on one of their beds. Zak lay down on the other bed and started messing around on his phone.

Megan went to the front and took the chain and locked the door, just in case their parents got back before they were done and to prevent a fast escape by either boy. She expected it by what she was going to do to them.

Megan went over to the bed and sat down across from Dylan.

“Tiffany and I were talking and we thought it was really fun hitting you guys in the balls. We want to keep doing it. And you're going to let us.”, she stated calmly to both Dylan and Zak.

“Umh I don't think so”, Zak exclaimed loudly as he sat up.

“Oh really?” Tiffany asked as she crossed her arms, looking suddenly mean and sexy in her swimsuit. “Megan and I know about your porn obsession. And we are not afraid to tell Mom. She’ll just love hearing that, don't ya think?”

“Oh, and Dylan. We know about you and your girlfriend having sex. You don't let us do whatever we want, mom and dad both know about it, too!” Megan said this with a sort of ‘we've got you now’ type of voice. Both Zak and Dylan knew they were about to do whatever their sisters wanted.

“We’re going to play a game. Megan and I are going to knee and kick you in the balls and we want to see who can get the other to fall first.”

The boys, realizing it was a lost cause both stood up. They were both afraid since both girls were extremely good soccer players.

Megan paired up with Zak and Tiffany paired with Dylan.

“First will be kicks!” Megan shouted with complete joy.

They were just about to begin when Megan made a decision. “Take your swimming trunks down boys. It'll be much easier for us without those baggy shorts in the way. We’ve all seen each other naked before, it's not a big deal.

Dylan and Zak glanced at each other and didn't appear like they would do it. That changed as Megan yelled for them to quickly take them off. They both nervously pulled their trunks down.

The difference between the two wasn't all that different. Zak, to no surprise being older, was a bit bigger in both his penis and ball-sack.

“Ready Megan?”

“You bet. On the count of three.”

One. Two. Three. In a flurry, both girls began kicking their partner as hard as possible. Megan took a step back and launched a kick with her long, beautiful legs straight into Zak's balls. Tiffany did the same thing. It was almost over as quick as it started. Zak fell after the third kick.

“We forgot to mention, the loser gets his balls squeezed by both of us,” Tiffany said excitedly. Tiffany made this up on the spot, but Megan played along. Both girls grabbed Zak's ballsack and gave his balls a five second squeeze.

Zak and Dylan were already in large amounts of pain, but they both began to get hard due to the fact that their sisters were very good-looking and especially so in their swimsuits. Each kick and knee caused Tiffany's breasts and thighs to jiggle about in her bikini as she playfully dominated her brothers, and soon the boys were fully erect. This only made the girls laugh even harder between hits as they built up a sweat.

This continued for seven more rounds. The girls went from kicking to kneeing and then punches. They switched partners and let the boys recover for a few minutes every time.

Megan had won four rounds and Tiffany three. They had begun the eighth round and were in the process of kneeing them as hard as they could when the side door opened and their mom came in. They had forgotten to lock that door.

“What is going on in here?” Taylor stuttered, almost at a loss for words. “Why are your brothers naked? And w-why are you kneeing their testicles?”

Zak and Dylan became very red in the face, and tried to hide their erections, not knowing what to say.

“Why are you home, Mom? We didn't think you'd be here for a while,” Megan said sheepishly.

“My dress wasn’t very comfortable, and I decided to change it before we went to the movies.”

Zak and Dylan attempted to descretely put their clothes back on.

“What are you two doing?”, their mom asked harshly. “No one said you can put your clothes back on. You’ll keep them off until told otherwise. The girls already had their fun, but I haven't. I don’t think your dad wants to be left out, so I’ll call him to come up and join us in this family experience.”
