Kate and Adam: Sister cracks some nuts while playing a video game

As he dropped his book bag on the ground and stretched his arms out, he let out a tired sigh.

“Ah, *finally!* I thought finals week would never end!”

Adam, a college junior of average height and build, lazily walked down the hallway of his house as he made his way to his room for a much-needed nap. Before he could make it to the end of the hall, he heard an all too familiar voice call out to him, stopping him in his tracks.

“I don’t think so, mister!” the voice exclaimed. “I’ve been waiting for two days now for you to finish your finals. It’s time to play that new fighting game! I’m *definitely* beating you at this one!”

Adam turned to find his younger sister standing in the doorway to the living room. Her brow furrowed as she pouted, obviously upset that her brother had forgotten these supposed plans.

“Give me just a little bit, Kate. At least let me shower first.”

Kate, Adam’s younger sister and sophomore at the same college. She was almost as tall as he, with a slim, athletic body and average-sized breasts. Her bright blonde hair contrasted sharply with her deeply tanned skin and dropped down to her waist. Her fit body was barely covered by her tank top and her track shorts. She walked out of the doorway, putting her hands on her hips as she puffed her cheeks out in annoyance.

“Fine, but you’d better hurry up, numb-nuts! The game’s been out for a week, and I’m sick of waiting on you to play!”

Adam blushed and quickly walked to his room, embarrassed by his sister’s crude name-calling. He retrieved a clean pair of basketball shorts and a t-shirt from his dresser before making his way to the bathroom, entering the shower, and letting out a relaxed sigh as the warm water washed away the fatigue from his long day of tests. After getting out and drying off, the young man started getting dressed before letting out an annoyed grunt.

“I keep forgetting to get some new clothes. These have gotten so tight!”

While he was of average build in most places, he was rather well endowed, and since college had started, he'd been having trouble fitting into his old shorts. After pulling them up, he adjusted himself to try and hide the very obvious bulge before making his way to the living room to find his sister sitting on the floor turning on her game console.

“Alright,” he said. “I’m ready.”
“About time!” she responded. “I’ve been waiting all-”

Kate turned to face him as she spoke but fell silent when her eyes met the large bulge in his shorts. She smirked, looking up at his face.

“Seriously, dude? When are you gonna get some new clothes? Aren’t you embarrassed to be showing that stupid dick to your sister?”

Adam’s face flushed a deep red at her words, and his hands darted to cover the offending bulge.

“I-I’ve been so busy lately, and I haven’t had time! Not everyone got to get all their finals done in two days like you did! Why do you always have to point it out?!”

“Because,” she responded. “You won’t hide that stupid cock. Or is it your balls that are so big I can see them from a mile away?”

She started giggling to herself as she grabbed the two controllers and sat down on the couch. She beckoned him to sit next to her and handed him the 2nd player controller. As the console booted up and the game loaded, the toned blonde kept shifting her gaze to her brother’s crotch, snickering as he shifted uncomfortably from the pressure the tight clothes were putting on his most sensitive place.

“I think I’ll just stand while we play.” Adam said, shifting his weight forward.

“I don’t think so!” Kate replied, putting her hand on his chest and pushing him back into the couch. “I’m not letting you have an advantage like that!”

“How would that give me an adva-” Adam started, but was cut short by the music signaling that the game was starting. He quickly picked up his controller and steeled himself for the match. “Fine, but just a quick game!”

The match started, and the room went silent except for the sounds of two sets of hands furiously smashing the buttons on the poor controllers. While Kate was quite the fanatic of these types of games, Adam usually had little difficulty beating her. The match kept going as expected, with Kate’s character taking hit after hit until she was only a few moments from losing. Before Adam could land the final blow, Kate’s eyes darted from the screen to her brother, whose entire focus was the game, leaving his real-life weak point completely exposed. She sent her hand flying, smacking the back of her hand into his balls and causing him to yelp in pain. He dropped his controller and frantically grabbed his crotch, kicking his feet and bringing his knees together. Kate took this opportunity to finish off his game character, winning the match.

“I knew it!” she exclaimed, throwing her hands in the air. “I’m the best!”

Adam looked to her, his hands still clutching his aching balls. “What was that for?! That’s not fair!”

“Didn’t you know? That’s part of the game too! You have to protect your real-life weak points just like your game ones!”

“That’s not-”

Kate interrupted her brother, handing him the controller and starting a new match.

“This time, make sure you have *all* your weaknesses protected.”

She gave him a sly wink as she started playing, quickly hitting his character multiple times. He tried to fight back, but was too distracted by the throbbing pain in his balls to put up much resistance. After a flawless victory, she looked to her brother still clutching his jewels and laughed.

“Seriously? Is this all it took? I could have been beating you all these years if I’d just been cracking your nuts during the game?”

Adam blushed at her comment, feeling humiliated that his little sister had not only hit his most sensitive place but was now mocking how much pain he was in. He picked up the controller again, steeling his resolve.

“Let’s go again!” he exclaimed. “I’m seriously beating you this time!”

“Oh yeah?” she responded. “How are you going to beat me if I just reach over and smack that stupid cock around? I’ll finish you off while you’re crying on the floor.”

“Because this time you’re not allowed to take your hands off your controller!”

“That’s not fair!”

“What’s not fair is slapping my balls while we’re playing!”

The two siblings bickered back and forth until Kate went silent. A devilish smile spread across her face as her eyes darted between her brother’s eyes and crotch. She leaned in and whispered in his ear.

“Fine,” she cooed. “I’ll keep both my hands on my controller the entire time. But in return…”

“In return?”

“If I win, I get to kick your balls as hard as I can.”

“What?! But—”

“And you have to take those stupid shorts off when I do!”

Adam’s mind started racing. *As hard as she can? While I’m naked?! Just that slap hurt so much, but if I could beat her and wipe that stupid smile off her face…*

“Fine,” he responded, confidently. “You’re on.”

“Nice! I can’t wait to pop those stupid balls of yours. I wonder if they’ll still work when I’m done.”

Kate pressed the start button, and the match began. Adam leaned forward in his chair, all of his focus placed on his game character and reacting to his sister’s attacks. After a couple of minutes, Adam was nearing victory. He could hear his sister’s groans of frustration, but he didn’t let them distract him from the screen. As he went to land the final blow, he felt a sharp pain in his hip, looking over to see his sister lying on her back, launching her foot at him, her focus shifting between her in-game target and her new real-life one.

“W-wait!” Adam stammered. “The rule was—”

“The rule was I wouldn’t take my hands off the controller.” Kate responded casually. “You didn’t say *anything* about my feet!”

The pair looked away from the screen in unison, their gazes meeting before Kate’s eyes quickly darted to her brother’s crotch, her foot rising in the air. Seeing her intent, Adam dropped his controller and tried to guard himself, but he was a second too late. His sister’s foot plunged into his lap, her hard heel smashing his already sore balls. He grabbed her foot, bucking his hips in pain as he cried out.

“My balls! My *balls!*”

Kate giggled at her brother’s suffering, casually sitting up and easily winning the match. She set her controller down, leaning over and putting her hand around her brother’s shoulders as he continued to squirm and moan from the intensity of his uniquely male pain.

“You ready for your punishment, numb-nuts? Well, I guess you *wish* you were a numb-nuts right about now!” She laughed at her own joke as she stood up, making exaggerated stretching motions as if she were about to run a race. “Alright, take em’ off. Time to smash those balls!”

Adam looked at her in horror before forcing himself to stand up. She signaled for him to take his shorts off, but he froze.

“C’mon, Kate. Do we really need to—”

“Take them off; that was the deal!”

As Adam continued to stand frozen in place, his sister approached him, grabbing each side of his shorts and forcefully pulling them down. As if thankful to be freed from the restrictive shorts, his large dick and even bigger balls swung back and forth before resting in their natural place. Kate looked down at them, giggling girlishly.

“So it’s your cock *and* balls that are so big! I’m surprised this huge thing has even *survived* this long with how tight your shorts are.” She took a couple of steps back, bringing her right foot back and focusing on her target. “But I guess it doesn’t matter now. They *definitely* aren’t surviving *this*!”

As the intense pain and humiliation became too much for him, Adam started shifting uncomfortably as he noticed his dick starting to rise. While he was impressive while soft, he was even more so hard. His sister paused her kick, pointing and laughing at his exposed erection.

“What the hell is that?!” she giggled. “Why is your cock getting hard? Is it scared this might be its last chance to cum before I break its balls?” She walked up to him, bending over and bringing her face close to the head of his dick before playfully taunting it. “Sorry, mister cock, but no cumming for you! Say goodbye to these big nuts of yours!”

She backed up again, taking her kicking position before taking a deep breath. The room went silent, and the young woman’s once bright and smiling face was now stone cold, completely focused on the destruction of her brother’s manhood. Adam watched in horror as his beautiful sister took a stride forward, launching her bare right foot into his large, exposed balls, crushing them into his pelvis and lifting him onto the tips of his toes. The silent room was filled with a loud slapping noise followed by Adam’s screams as his hands darted to his crotch, desperately clutching his throbbing balls. He dropped to his knees as his screams turned to tortured moans.

“My balls! Oh my god, my *balls*!”

As he continued to mewl about the damage to his manhood, Kate pointed and laughed, mocking her brother’s pathetic form.

“Oh my balls… My *Baawwwllls*…” she mimed, walking up to him and kneeling down to meet his face. “How was that? Did I crack those big nuts? Think they still work?”

As he continued to moan, she reached between his legs, grabbing his still-hard cock and pulling it up for inspection. She moved his erection around, teasingly pretending to check it for possible damage before letting go and roughly slapping its head, causing his dick to bounce up and down.

“Nope, they still work. I’ll just have to crack them next time!” She stood up, staring at the results of her impressive kick. She started to breathe more heavily as she took in the sight of her older brother being completely dominated by a single kick. “You know,” she said. “I think I could get used to this.”

After a few minutes, Adam’s body finally started to relax. He slumped down before landing on his side, his hands still cradling his battered jewels. He looked up to see his sister sitting back on the couch, readying the game for another round. She looked down at him, her cheeks slightly flushed and an excited smile on her face.

“Ready for round two?”
