Gwen has never been very fond of her step brother Brandon, but her distaste for the boy has only grown stronger the past few months since they had begun living together full time.
Gwen had never thought of herself as an uptight kind of person however she had never lived with a 19 year old boy either, the smelly socks, ball scratching, late night gaming and parading around in his underwear would be enough to put any girl off but the last straw for her came on a quiet summer morning.
Gwen awoke like normal and found herself making her way to the kitchen for a bowl of cereal or really anything she could get her hands on to satisfy her empty stomach. As she reached for a bowl she put her hand on the countertop and recoiled in disgust as she felt a sticky, slimy substance coat her hand.
To her horror when she looked down she was met with her hand covered in a white slimy liquid, when her eyes trailed back onto the counter she saw that said liquid was laid out in 4 distinct ropes, in that moment it clicked in her mind and she audibly gagged as she rushed over to the sink as fast as she could.
"Fucking disgusting prick!" She screeched as she furiously scrubbed Brandon's seed off of her hand.
After she had scrubbed her hand nearly raw she threw some paper towel on the mess he had made and stormed up to his room, she slammed the door open and to her surprise the room was empty, she took a deep breath but instantly regretted it as the stale smell that came from the boys room nearly knocked her on her ass.
She went to leave the room but then thought for a moment, why not take the opportunity to do some poking around?
As she entered the room more she saw a trash bin overflowing with used tissues, she can only imagine what those were used to clean, then she looked at the boys desk. To the right of his computer was a black cylinder, it looked like a container of some description? She got closer and when she unscrewed the lid she was horrified to find out this 'container' was in fact a silicone vagina.
"Fucking perv!" She exclaimed as she tossed the item to the side.
Back on his desk she opened his laptop and to her delight he hadn't put a password on it. First she clicked google and as she opened it she was bombarded with multiple flashing porn sites with bright pictures of girls with huge tits.
"How typical..." She sighed as she clicked through the multiple links he had still open on his computer, at least 90% of them were porn and the other 10 were a mix of his discord and some online games him and his friends would play. His discord peaked her interest and she continued to investigate.
One of the first servers that came up was named "Gooners paradise", "what the fuck is a gooner?" Gwen said as she clicked the server.
The first image that popped up was a picture of a man that didn't look much different from her step brother, lean and young, however in this picture the boy had a tight grip on what looked like an extremely hard erection with the caption underneath reading "Never stop pumping".
She quirked an eyebrow as she continued looking through the pictures and messaged sent in the chat, then she stumbled upon a channel he had just posted in that night and read his message.
"Just left a huge load in the kitchen for my step sis to see! I've been going all day and I couldn't hold back any longer"
Underneath was an image, it was a picture of the counter with his then fresh load plastered all over it and in the bottom of the frame was his still rock hard cock.
"Oh... wow" She said under her breath as for a brief moment she admired the sheer size of his massive uncut cock. It must have been at least ten inches of thick meat that was hanging between the boys legs.
She got over it quickly though as she remembered how disgusting she found every other aspect of the boy, sure if he wasn't her step brother maybe he'd be attractive but because of their relationship she could easily find a way to hate everything about him.
Then she reread the message and realized that he had explicitly mentioned her.
"He... wanted me to see it?.... what the fuck?!" She thought as she scrolled down and saw replies from his friends.
"Nice! I bet she'll lick it up like the slut she is dude"
"Motherfucker!" She exclaimed as she kept scrolling.
As she clicked onto another chat her jaw dropped as she tried to process what she was seeing, Brandon had been sending bikini pics from her instagram to this server!
Before she could look any further she heard the front door open.
"Fuck!"
Before she could get out of the room she heard his footsteps coming up the stairs and she found herself having to make a quick decision and dive into his closet just as he swung his door open.
Brandon sighed as he slumped into his desk chair and looked at the computer.
Gwen held her breath as the smell of dirty laundry and old cum socks filled her nostrils.
Just as the room went quiet Gwen heard a faint slapping sound and soon the sound grew louder and louder.
*PLAP* *PLAP* *PLAP* *PLAP*
She had to stop herself from laughing as she realized what she was hearing.
"Fuckk..." Brandon groaned deep as he swung his head back.
"Is he really jerking off right as he got home?" Gwen thought to herself as she tried her best to stay as silent as possible.
"Gwen..." Brandon groaned.
Thinking he had spotted her she began to exit the closet and was about to make a hasty exit, until she realized he hadn't turned around and had headphones on.
"Take it you fucking bitch!" He said in an angrier tone as his pumping sped up considerably, by now the sound of Brandon stroking his fat cock was almost comically loud.
"Is he?... jerking it to me?" She thought as she peered over his shoulder and saw something she never expected to see on his screen, presented brightly on his laptop were some very private images she had sent to her last ex boyfriend and she had thought he deleted them.
Until now Gwen was beginning to actually feel slightly endeared and flattered by her step brothers perving, but this was too far. She had no idea how he had gotten those images and she was about to make that little pervert tell her.
She remembered a scene in a movie the family had watched a while ago that had made both her step brother and step father squirm in their seats, the heroin of the movie had grabbed one of the villains henchmen by the balls and was interrogating him, when she was done with the poor man she squeezed her fist tight which resulted in a sickening crunch and the henchman falling to his knees.
As she approached Brandon from behind she got a better look at his crotch, he was furiously stroking his reddened cock and was causing his plum sized balls to bounce up and down violently.
"Nice big targets, that'll make this easy.." She thought to herself as she lunged forwards and sunk her acrylic nails deep into his soft nut meat.
Brandon's entire body went extremely rigid as he felt a dull pain begin to grow in his squeezed testicles.
"Oh god.." He squeaked as Gwen used all her might to yank him onto his feet by the balls and drag him into the middle of the room.
\"Where did you get those?!" She screeched as she applied even more pressure to his sensitive balls.
"I- I bought them from Tony!" He replied with tears beginning to form in his eyes.
"Fucker!" She shouted as she yanked his balls towards the ground.
"Oh god.. not my balls!" Brandon sobbed as the pain from his balls really began to set in.
"You sick fuck! You have a real fucking problem!" She said as she kept her ball crushing grip tight on his plums.
Then an idea popped into her head, from what she had seen today it was clear that Brandon was too far gone to be properly rehabilitated into a normal man who doesn't jerk off to his step sister, that is unless two particular nasty, hairy things were removed from between his legs.
"You know what Brandon? I'm going to do you a favor today" She said as she looked into the boys frightened eyes.
"Boys like you have no chance of ever being normal again, you went too far down the hole to ever come back out, and I mean I can't even blame you, with a cock like that I'd be sitting around all day playing with it as well" She went on.
"But if we're going to live together something is going to have to change...." She said as she gripped his massive balls with one hand and used her other to trace the frightened boys jaw.
"Do you know where all of man-kinds problems come from Brandon?" She asked innocently, he shook his head no looking scared and confused.
She smiled and pointed down at his trapped balls. "Right here, where all that nasty testosterone comes from!... I bet these things right here are the reason you joined that stupid 'gooner' group anyways!"
"What are you trying to say?!" Brandon responded seeming a little angry and offended.
"I'm saying that just like a fucking dog that needs fixing you do too."
It took a second for Brandon to register what it was that she was saying but just as he put two and two together Gwen was slamming her fist down onto his sensitive plums.
*SMACK*
Brandon's pretty blue eyes went as wide as they'd ever gone in his life as he felt a pain like no other radiate from his prized family jewels.
That's when Gwen had another devilish idea, if she was going to pop this dumbasses balls she was going to fucking film it!, and send the video that stupid server he was in as a fucking warning!
She reached over and began recording a video on Brandon's laptop, she then positioned the boy in front of the camera with her face strategically out of frame.
"What are you doing?" He asked frightened.
"Making a movie for your little friends!" She replied cheerfully as she stepped behind him and sent her knee rocketing up into his unprotected balls.
*SPLAT*
His balls were cruelly pinned against his pelvis as the shockwave caused his surprisingly hard cock to bounce comically, slapping his inner thigh as it did so.
"It'll be shame for you to have a cock that big with no balls!" She laughed as she sent her knee up into his groin once again.
*SPLAT*
The noise his balls made even sent shivers down Gwen's spine, if she wasn't the one inflicting this pain on her step brother she could've seen herself cupping her crotch in sympathy.
"Please Gwen! I'm a virgin! I can't lose my balls!" He begged.
"You were gonna be a virgin forever regardless" She laughed as once again her knee slammed into his now pink and red balls and slammed them against his body.
Brandon sobbed as the pain nearly caused him to fall to his knees.
"Please! I don't think they can take much more! I'm sorry! I'm sorry for jerking off to pics of you! I'm sorry for cumming everywhere, I'm sorry for stealing your panties!"
"Stealing my panties?!" She exclaimed as she took a step back.
"Oh.. you didn't know about that?" He asked looking embarrassed.
*CRUNCH*
Gwen swung her foot as hard as she could into his fat plums.
Brandon tried to scream in pain but all that came out were pitiful squeaks.
"No.... no I did not know" Gwen said through gritted teeth.
When she lowered her foot she saw on the computer screen just how fucked up Brandon's left ball now looked, it seems that the poor boys left nut took most of the damage because it had now swollen to almost double it's original size and was beginning to take on a purple hue.
"My ball!" He sobbed as he too took in the damage.
"Don't worry! I'll make them match!" She said excitedly as she swung her foot in-between his legs once again.
*CRUNCH*
"ooooh that must've been the right one this time" She said giggling as she lowered her foot once again to see that now both of his balls had taken on a worrying purple hue.
"Oh god! I'll never be able to have kids!" Brandon sobbed as he looked at his ruined manhood.
"Oh I wouldn't say that!" Gwen reassured him as she pushed him forwards causing him to fall into his desk, his fat nuts were cruelly pinched between his body and the edge of the wooden desk and because he had no hope of catching his balance, all of his weight bared down on his already broken balls.
*POP*
"Now you can't have kids!" She said with a grin on her face as she watched his rigid cock spurt out rope after rope of his sticky white seed all over his adorably shocked looking face. His cock twitched violently as it desperately tried to shoot it's final load before losing it's fertility.
"Fuckk I know this is a bad time but seeing you nut all over your face like that is getting me so wet!" She said as she stood beside her now nutless step brother. She then stopped the recording and swiftly sent it to Brandon's discord friends to see.
"I wonder if they'll still let you be a 'gooner' with no balls?" Gwen said poking at her still frozen step brother, the look on his face giving her nothing but pure sadistic joy.
"You know... maybe I over reacted..." Gwen said scooping a bit of his cum off his face and licking it off her finger.
"I would say let's try again but I don't think you're my type anymore... I'm into men.. not nutless losers!"
With that said Gwen decided it was time to walk away and let Brandon deal with whatever he had to deal with, who knows, maybe if he can muster up the strength to drive his way to the hospital they might be able to save his manhood, orrr maybe a sadistic nurse will make sure there's no hope of repair... either way Gwen was on her way to call Tony and have a nice chat with him too, maybe she'd even let him come over and fuck her one last time before she obliterated his worthless nuts as payback for selling her nudes. Either way this interaction had awakened something deep inside of Gwen, a desire she had never felt before but now she wasn't sure she'd be able to get enough of it.
