Bratty sister 7: Busted by aunt and sister's friend, and reconnection with my sister

Part 7 to the story, read the others first if you haven't

\*\*\*ALL CHARACTERS INVOLVED ARE AT LEAST 18 YEARS OLD\*\*\*

Slowly opening my eyes, I sat up in bed and looked around. *Nowhere to be seen.* My heart sank as I sat on the edge of my bed. For the first time in a long time, I had woken up alone. I closed my eyes and remembered the sensations of my sister slapping my balls first thing in the morning, and imagined her smiling face as she giggled while threatening to do god knows what to my nuts. *I gotta go find her!* I jumped out of bed, put my shoes on, and ran out the front door, running into the busty blonde that was about to ring the doorbell.

"Ouch!" Chloe cried.

"Sorry, I was in a hurry-"

\*slap!\* \*slap!\*

"Ohhh!"

Chloe had quickly gotten up onto her knees, kneeling over to give me two hard slaps to the balls.

"You're lucky we've gotta hurry and find Natalie!" she said, pouting and pointing down to my crotch. "Or I'd teach those stupid balls a lesson!"

Holding my balls, I looked up to Chloe, who today was wearing a loose-fitting hoodie and her usual frilly short skirt. The bagginess of her hoodie formed well around her figure, accentuating her large breasts.

I quickly stood up, grabbing Chloe's hand and dragging her along the sidewalk.

"Where are we going, Mr. Big Brother? Do you have an idea of where Natalie might have gone?"

"We're gunna check with my aunt. She lives a few blocks from here."

We walked quickly down the sidewalk, reaching Aunt Jess's house after a few minutes. I walked up to the door and rang the doorbell, still holding Chloe's hand. *Wait, that's right. She literally lives a few minutes away from us. Why the hell does she always wait months between visits?* The door opened, and greeting us was my busty Aunt Jess, still in her loose-fitting black tank-top and matching short shorts that she'd worn to bed the night before, and her feet completely uncovered. 

"There you are," my aunt started. "I figured you'd show up soon. Natalie is in the back room."

*Are you fucking serious? She ran away from home and traveled a whole FIVE MINUTES?!*

As I tried to wrap my head around the sheer stupidity of this entire situation, Jess turned to look at the busty blonde behind me, and then to our hands that were still held together. 

"Are you serious?!" Jess yelled, roughly pulling me inside and slamming the door shut. Your sister ran away from home crying, and you're fucking around with your *girlfriend*?!"

Chloe let out an embarrassed squeal, immediately swinging her arm and giving me a hard backhand to the balls. As I moaned and bent forward, Jess only became more angry.

"And instead of fixing the issue with your sister, your having your girlfriend bust your balls?! How about instead of getting your cock hard, you take some responsibility?!"

Aunt Jess started walking toward me, her brows furrowed and her teeth clenched.

"W-wait, Aunt Jess! Let me explai-"

\*Smack!\*

"Agggghhh!"

Aunt Jess had shot her bare foot up into my balls, smashing them into my pelvis and lifting me an inch into the air. As she retracted her foot, I crumpled to the ground, desperately clutching my nearly-destroyed nuts as the excruciating pain spread throughout the entire lower half of my body.

"You're lucky I don't castrate you, you limp-dick piece of shit!"

Aunt Jess put her hand on her hip and stared down at my pathetic form. After a few seconds of me writhing in pain, she started walking toward me, presumably to make good on her threat.

"Wait!" Chloe screamed, walking in front of me to block the rage-filled milf's path. "There's a misunderstanding, he didn't do anything!"

As I slowly made my way up into a standing position, my throbbing balls still in my hands, Chloe explained the situation.

"Ah, I see." Jess said, her hand on her chin. "I bet she really *was* embarrassed if you just called her out like that."

"I'm sorry, I'm sorry!" Chloe responded, her hands together as if she were praying to God himself for forgiveness. "I didn't know it was a secret! It seemed so *obvious*!"

Aunt Jess turned to me as I stood up, smirking as she watched my hands desperately clutching my ball sack. 

"I'd apologize for cracking your nuts," she said with an amused smile. "But I know you actually *liked* it. I almost destroyed those big balls, and your cock is already getting hard!"

Chloe turned to look and found that my aunt was telling the truth. My dick had risen to full mast within a matter of seconds from the devastating kick. The busty blonde clicked her tongue as she walked toward me and sent her open palm flying into my crotch, slapping my balls through my own hands and causing me to bend forward again.

"This isn't the time for you to start fucking around with that hard cock!" she exclaimed with an annoyed expression on her face. "We have to go and apologize!"

As I tried to stand up straight again, Aunt Jess let out a chuckle.

"That cock is never going to go down if we keep busting his balls, but that actually gives me an idea."

The big-titted milf walked up to me, pushing my hands away from my balls and aggressively pulling my shorts down to the floor.

"Hey wait!" I protested. "What are you-"

\*Smack!\*

"Oooohhh!"

Aunt Jess had quickly launched her open palm up into balls, causing them to bounce up and down and creating a loud clapping noise that resonated throughout the room. As I stood there clutching my balls, Jess turned to Chloe and pointed at my hard dick.

"We're gunna bust his balls nice and good, and when his throbbing cock can't take anymore, we'll send him into Natalie's room and let her finish the job." Jess smirked as she told her plan. "It'll be like Christmas morning for the little ballbuster!"

Chloe started to giggle as she watched my dick twitch from Aunt Jess' telling of the plan, and as she walked around to my back, she grabbed both of my arms and pulled them behind me. She pushed herself up against my back, and I could feel her massive tits pressing into me like two beanbags. 

"Okay!" she responded, obviously excited. "You can go first!" She turned to whisper in my ear, sending a shiver down my spine. "You'd better pray she doesn't go all out. She might actually end up *destroying* those big nuts of yours."

Chloe's sexy whispering in my ear caused my dick to twitch even more, and as my busty aunt strode forward into kicking position, my eyes darted right to the two massive tits staring back at me. As she pulled her right leg back, her breasts bounced up and down. 

"Enjoy the view, little boy." she said, licking her upper lip. "While you still can."

Aunt Jess sent her barefoot flying forward, crashing into my naked balls and causing me to yell out in pain. As I started to drop to the floor, Chloe brought her knee up between my legs, driving it into my balls from behind and causing me to stand up straight. Jess continued to send kick after kick into my exposed, vulnerable baby-makers, and with each cruel kick, I could feel my balls swelling up more and more. After the eleventh kick, the busty milf stood back, wiping the sweat off her forehead and bending over to inspect the damage.

"Oh my..." she said, a devilish grin on her face. "These big balls can really take a beating, can't they?" She walked up to me, putting her face next to mine and whispering in my ear as she fondled my throbbing, swollen balls. "Your uncle Robert could never have taken this much. After a few full-force kicks, he would be crying, and his cock would be useless." She moved her hand from my balls to my dick, quickly stroking up and down its length with a firm grip. "But this big cock *likes* getting kicked, doesn't it?"

*Oh my fucking god...*

Letting go of my dick, Aunt Jess walked around to my side and took Chloe's place behind me. She grabbed my arms and held them behind my back as Chloe walked around to face me from the front. 

"On the ground!" Chloe yelled excitedly.

"Yes ma'am!" Jess responded.

Aunt Jess pushed me to the ground, causing me to land on my ass with my legs spread. Chloe walked up to me, and as I looked up at her, she winked devilishly at me before swinging her foot back in an arc.

"Say goodbye to those big, stupid nuts!"

Chloe swung her foot forward, crashing it into my balls and causing me to buck my entire body in an attempt to escape. Jess redoubled her hold on me, wrapping her arms around my chest and tightly hugging me. I felt her tits squishing into me as I watched Chloe send her foot into my balls over and over. After only six kicks, I started bucking my hips, and when she noticed, Aunt Jess called for the excited blonde woman to stop.

"Alright, that's enough." Aunt Jess said, letting go of me as I fell back onto the floor.

"What?" Chloe protested. "But I only gave him a few kicks!"

Jess pointed down to me, and Chloe followed her finger to see me moaning on the ground, hips bucking into the air and dick twitching like crazy.

"Any more, and he's gunna cum all over the place. Chloe, help me pick him up."

The two big-titted women helped me up off the ground, each one taking one arm and pulling with all their might. Once I was stood up, I tried my best to catch my footing. *Oh my god, oh my GOD*. Using all of my willpower not to cum, I looked at Aunt Jess. She pointed down the hall to a door on the end, stepping out of my way and crossing her arms under her massive breasts. 

"Go on now, boy. Give the girl her prize." She looked down at my throbbing dick. "And if you cum before you get there, I'll seriously castrate you."

My dick started twitching again at the threat, and she panicked.

"No, no, sorry. That's just bringing you closer to the edge, isn't it?"

Before the two sexy, busty women could torture me any more, I made my way down the hall. 

"You can do it, Mr. Big Brother!" Chloe cheered at me. I turned and nodded at them, then grabbed the handle and opened the door. 

Moving through the door, I found my sister laying on her side in a small bed. She had on a loose-fitting white shirt and white panties. As she had earbuds in and was watching something on her phone, she had not yet noticed me. I walked around to her side, looking over her shoulder to see what she was watching. On her phone screen, I saw a video of a woman viciously kicking a tied-up man in the balls. As she watched, Nat squirmed slightly and rubbed her thighs together. *It hasn't even been a full day, and you're already watching ballbusting porn videos?* As I continued to watch behind her back, I started to get more turned on. *What the fuck, this video's really good.* I leaned forward to try and catch the title at the top, but as I got closer, the petite brunette noticed me, turning quickly in a panic.

"It's just me! It's just me!" I whispered to her. "Chill out!"

She froze in place and, after a second, relaxed and let her head fall into her pillow.

"Jeez you idiot! You're gunna give me a heart attack!"

She pouted as she looked at me, and then, having a sudden realization of what was still playing on her phone, jumped up to try and hide it. 

"I already saw."

"W-what?..."

She turned back to me, face beat-red.

"I-I was just-" she stammered, trying to find the magic words to get her out of this embarrassing situation.

"I know you like it." I interjected. "It's okay, everyone knows." I leaned in close to her, taking the earbud out of her right ear and putting it into my own. 

"W-wait! What are you-"

"Let me watch it with you."

She froze in place, and with her hands trembling, she slowly brought her phone out. Her finger hovered over the play button, her eyes staring in to mine as if to say, "Is this a trap?" I gently grabbed her hand and moved it forward, starting the video. As the video started playing, we cuddled up to each other, each having an earbud. The woman in the video was viciously kicking a tied-up man in the nuts, and with each kick, the man hollered in pain. After a minute of watching, I looked over to see Nat biting her bottom lip and rubbing her thighs together. I took the phone from her hand, leaning in close to whisper in her ear.

"My dick is hard. Bust my balls while we watch the video."

Nat looked down to see my throbbing-hard dick, and as she started to tremble from excitement, she slowly wrapped her hands around my swollen balls. As she started to apply pressure to my nuts, we re-adjusted our laying position as I held the phone up in front of us. As the video continued and the actress's kicks became harder and more cruel, my sister and I started to gently moan, her from excitement and myself from pain. 

"She's really good." Nat said under her breath, admiring the devastation the actress was inflicting on the poor man's exposed balls. "She might *really* crack his nuts if she keeps going like that."

*Oh my fucking god, Nat. You don't know what you're doing to me.*

As I started to buck my hips, I could feel myself nearing the point of no return. Nat looked down at her targets, biting her bottom lip. 

"I don't need the video!" Nat said between labored breaths. "I'm gunna crack these nuts!"

She moved to a seated position between my spread legs, sitting on her knees as she leaned down and focused all of her attention on my swollen balls. I laid my head back into the pillow and moaned loudly, all of my concentration on the sensation of her soft hands slowly destroying my most vulnerable place. As the bed started to rock, I looked down to see the now-familiar sight of my sister bucking her hips in excitement. She removed her hands from my balls, pulling her right hand back and balling it into a fist. 

"That filthy cock will never work again!"

Nat launched her fist into my exposed balls, causing an explosion of pain to run throughout my entire body. She moved one leg over my own, straddling my right thigh as her bucking quickly turned into grinding. She let out a loud moan as she furiously grinded her pussy into my leg, and as she sent more and more punching into my balls, I felt myself nearing my climax. My hands quickly moved to my dick, and as I ran them up and down its length, I started bucking my hips. 

"Nat, NAT!"

"Your balls! I'm gunna fucking *destroy* your balls!"

"Ohh Nat... OOhhh!!"

"Ahh... AAHHH!!"

Hitting my climax, I came into the air, landing on Nat's face and in her hair. As my vision blurred and my senses dulled, all I could hear was my sister's orgasmic screaming as she continued to punch my balls and grind her pussy into my leg. When the movement in her hips finally stopped, she fell into my chest, completely limp and breathing heavily. I tried to think of what to say before realizing that there was no way I was going to muster the energy to say anything at all. *Jesus Christ...* As my consciousness began to fade, I wrapped my arms around my sister's back, feeling her petite frame rise and fall with each gasping breath. The last things I heard before the world went black were the door opening and the sounds of two impressed women commenting on the mess that we'd made. 

As I slowly started to come to, I hazily looked around the room to see that I was alone. I got up to the edge of the bed and felt a throbbing pain in my crotch. I looked down to see my naked balls swollen up to twice their size again. *She always does a number on my nuts, doesn't she?* I forced myself to get up, walking to the door and entering the living room. In the large living space, I saw the three women happily chatting away. As I walked toward them, Nat noticed me, turning toward me with her face turning red.

"I'm coming home!" she exclaimed.

"Oh, yeah. That's good." I said, still half-aware of my surroundings.

Nat angrily walked up to me, swinging her arm and giving me a light slap across my naked ball sack. Though not hard enough to cause me any real pain, I moved my hands to grab my crotch.

"Jeez!" she said, aggravation clear in her voice. "You don't sound very happy! You'd better straighten up or I'll *really* smack those balls around!"

The blonde woman behind her started to giggle, and Nat turned back to continue her conversation. As they chatted away, I looked around and found my shorts on the ground. I re-covered myself, put my shoes back on, and headed toward the door. Opening it, I turned back to see my sister watching me go. 

"I'm glad you're coming back." I told her. "I'm really tired, so I'm gunna head back. I'll see you at home."

My sister simply smiled and waved at me as she continued her conversation, and it would have been a wholesome moment if the topic of said conversation wasn't the intricate details of the damage she had just inflicted on my balls. As I walked down the sidewalk, I breathed a sigh of relief. *I guess it all worked out*. Continuing to walk, I felt an increasing pain in my balls and noticed that the throbbing was getting worse. *But I need to put some ice on my nuts when we get home!* I hurried back home to start treating my damaged balls, as I knew I would need to be prepared for what my bratty little sister had in store for me next.
