A Step Brother’s Crushing Defeat

A Step Brother’s Crushing Defeat

By BdanmanBB

"Dude... will you stop digging at your fucking crotch?" Katie scoffed over at her step brother, Aaron, whose hand was buried deep into his gym shorts for the tenth time in the last 5 minutes.

"I can't help it! Mom keeps buying me underwear that doesn't fit!" he shot back defensively, still actively adjusting himself.

"You're 18 years old! You still let mom buy your underwear?!" Katie cackled.

"Uh yeah... I don't see the big deal." he said dismissively.

"Well judging by the way you're digging at your balls right now, it doesn't seem like she knows what size to buy."

"I mean mom doesn't buy my bras, I need to go try them on to make sure they fit. How would she know... you know... how big you are?" she asked glancing down at his crotch.

"I guess you're right... my balls are pretty massive…" he smirked.

"Oh please... don't flatter yourself." she scoffed.

"What? You don't believe me?" he said in an annoyed tone.

"Every guy thinks he's sooooo huge and then.... Boom. Disappointment." she said thinking back to many of her sexual encounters as Aaron quickly stood up from the couch and suddenly dropped his shorts, hell bound on proving her wrong.

Katie's eyes widened at the unexpected site before her, Aaron's balls actually were fucking huge and further accentuated by a comically small cock. They hung down like two pendulous limes, far lower than any pair she'd ever seen. While her immediate reaction was shock and surprise, she soon realized the humor of the situation and couldn't help but giggle.

"I told you they were big!" he laughed seeing her reaction.

"You're all balls! Where are you hiding the rest of your cock?!" she cackled at the little nub sitting so far above such a massive set.

"Hey now! That's a low blow sis..." Aaron smirked unphased by her teasing.

Katie, always ornery, flashed an evil smile at his comment. Without warning, she suddenly shot her foot up between his legs connecting with her step brother's fat nuts dead on launching them upwards towards his body with a loud smack. She knew instantly that her accuracy was dead on.

Aaron's eyes bulged and a look of betrayal overtook his face before finally sinking down to his knees cradling his injured balls, as waves of pain cried throughout his body.

"Now THAT was a low blow!" Katie cackled loving the feeling of her converse shoe connecting with his fleshy organs.

"Why???" he gasped as his stomach churned.

"Oh come on! That was funny dude!

"Bam! Right in the family jewels!" she exclaimed playing the kick back in her head.

"Ughhh... I think I might puke." Aaron groaned.

"It wouldn't be the first time I made a guy puke!"

"How proud of those balls are you now?!" Katie cackled, making fun of her brother's weakness.

"Not funny... My fucking balls." he continued groaning finally lying down onto his side trying to find some semblance of comfort.

"Do you think it hurts more than normal since your balls are so big?" Katie giggled seeing him continue to reel in agony on the floor.

"I can't believe you booted me in the fucking nuts like that."

"You served 'em up on a silver platter! What was I supposed to do??"

"I was just going back to my old softball days. See ball, hit ball!" she cackled.

"Not cool, Katie! This fucking hurts."

"Oh, you'll be alright in a minute you big baby." she scoffed unsympathetically having dealt with period pains all week.

"Also... it's good for you guys to learn every once in a while how weak you are." she said leaning forward to give her step brother a playful slap on the ass.

"I'm just doing my sisterly duty in turning you into an upstanding young man."

"Ughhh... fuck you."

Aaron, not wanting to look like even more of a pussy than he already did, mustered up enough strength to prop himself with his head between his knees, focusing on taking deep breaths as his now swollen balls rested on the cool, wooden floor providing at least some sense of relief.

"You really do have quite a nice pair on you, bro." Katie giggled looking down on his hefty sack, very tempted to kick them again as they sat there so vulnerable to attack.

But ultimately she figured she would take it easy on him until, of course, her step brother decided to open his mouth...

"God. You're such a fucking cunt sometimes." Aaron said still frustrated by the pain, trying his best to breathe away the pain.

"You know I hate that word." Katie said in an eerily calm tone as fire flashed in her eyes.

"Well if the shoe fucking fits!" Aaron quickly yelled back.

Scooting forward onto the edge of the couch, Katie reached her foot out towards her unsuspecting step brother whose eyes were closed until he suddenly felt the cool touch of rubber on his recovering testicles. As he opened his eyes, his new worst fear had come true at the sight of his sister's converse firmly pinning his low hanging balls against the unforgiving floor. Katie smiled as she began to press down, just enough to begin making him incredibly uncomfortable.

"You were saying..." she giggled knowing she had him completely on the ropes beginning to press down even harder.

"Katie... please... please don't." he stammered as an immense pain began to radiate.

"Please don't crush them." he begged.

"Why shouldn't I?" she asked, now just trying her best to toy with the fragile young man as she pressed down even harder, flattening them against the floor sending her brother into an instant frenzy.

"I need them!! Oh God, please have mercy!" he sobbed into the air feeling his manhood being compressed into oblivion.

"Are you done calling me a cunt?" she asked calmly with a big grin on her face.

"Yes! Yes!" he squealed.

"And are you going to clean the house for me today?"

"Yes! I'll clean fucking everything!!"

"Awww that's so sweet of you." she giggled pressing down even harder, unsure his balls would be able to take much more.

"And maybe a foot massage too?"

"I'll do whatever you want! Oh fuck, just please stop crushing my balls!!!"

"Now tell me how small your dick is." she said, her tone unphased by his discomfort.

"It's small!!! It's so fucking smalllllll!!!"

While basking in these moments of pure power and superiority, Katie suddenly noticed that was once a pathetic little nub, was quickly growing into a raging boner. A most unexpected surprise.

"Katie!! Please!!" he begged once more causing Katie to finally raise her shoe off his nuts allowing him the ability to function once more.

"I can't believe you just popped a little boner." Katie giggled standing up from the couch as Aaron's eyes went wide looking down only to realize he was hard as a fucking rock.

"It's going to be a fun day." she smirked before suddenly stomping her foot down hard onto her brother's balls, mashing them into the floor with the heel of her shoe as Aaron let out a blood curdling scream.

"We're going to put those puppies to good use today.... if there's anything left!" she cackled walking out of the room leaving her step brother in a sobbing ball of emotions.
