Bratty sister 7: Busted by aunt and sister's friend, and reconnection with my sister
By Floyd-kun
*
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.

Part 8: A bath together, and a new punishment
As I lowered myself into the tub, I let out a sigh of relief and sank into the warm water. I reached down and cupped my balls, still sore from the events at Aunt Jess's house. It's a good thing I iced them as soon as I got home; they were pretty swollen after Nat was through with them. Pleased that my still-sore balls were almost back to their normal size, I leaned back and rested my head on the bathroom wall. As I started to drift off, I must have lost track of time, because when I suddenly heard a knock on the bathroom door, I realized that Nat must have come home. She opened the bathroom door, wearing only a bath towel covering everything from her armpits to her upper thighs.
"You'd better not be playing with that big cock in here, mister!"
My freckle-faced little sister quickly moved to the edge of the tub and looked inside quicker than I could cover myself. Thankfully, as I had just been half asleep, I was completely soft. Despite always claiming that she busted me to keep my dick in check, Nat's frown revealed her disappointment in the limp dick staring back at her from under the water.
"Well, I know how you get if I leave you alone too long, so I'll just join you!"
With these words, Nat removed her towel, quickly using one hand to cover her modest breasts and the other to cover her crotch. She swiftly moved into the tub, sitting between my legs and facing away from me.
"Nat!" I yelled, completely dumb-struck that my sister had so casually gotten into the bath with me. "What are you doing?!"
"Relax." She told me, leaning back and resting her body on my chest. "I've seen that big cock and those stupid balls a hundred times by now."
Despite her acting, this bratty young woman wasn't fooling anybody. I knew she was just trying to get me hard so she would have an excuse to bust my balls. I remembered the last time she'd gotten in the bath with me and remembered how she slipped and fell when she tried kicking my nuts. I steeled my resolve, diverting all my mental energy to keeping my dick soft. The petite brunette let out an annoyed sigh, unable to hide her disappointment that she had not yet achieved her goal of giving me an erection. She scooted back into me, pushing her soft ass into my crotch and causing my dick to start twitching. Keep your cool, little dude! You gotta stay soft! She leaned her head back, resting it on my shoulder as she let out an exaggerated, sensual moan.
"The water sure feels good!" she moaned, quickly darting her eyes south to see if her half-baked seduction techniques were doing the trick.
While Nat's attention was on her moaning and grinding into my crotch, my eyes were glued to her chest, which was now clearly visible. I stared at her modest breasts, rising and falling with each breath she took and each moan she made. I shifted my gaze between her bright pink nipples, and then down to her belly button. As my eyes desperately tried to see what lay beyond, she quickly got up onto her knees, turning to face me with one arm over her chest to cover her breasts.
"Ew, you pervert!" She yelled. "Your hard cock is pressing against my butt!"
Despite her acting, she had a lust-filled smile on her face as she stared down at my hard dick. She moved forward, bringing her right knee up and gently resting it over my balls, trapping both of them between her knee and the floor of the tub. As she adjusted her position, my eyes remained glued to her naked body, causing my dick to throb. She giggled as she watched my erection bounce and twitch, then leaned into me, pressing her chest against mine and hugging her arms around my neck to balance herself. I felt her small breasts squish into my chest and could feel that her nipples had hardened. She rested her chin on my shoulder and whispered in my ear.
"Stay still. I'm gunna flatten these big, stupid balls! If you make me lose my balance, I'm popping them!"
With this, Nat leaned forward, shifting her weight to her right knee and pressing my balls into the floor of the tub. I tensed up, my hands wrapping around the petite brunette and resting on her hips as I snuggled my face into her neck. While concentrating on the sensation of her knee crushing my most sensitive place, I moved my hands up and down her lower back, feeling her soft skin and the curves of her hips and ass. She giggled as my hands made their rounds.
"Geez, that tickles! You're gunna make me fall!"
She lifted her free knee off of the floor of the tub, allowing all of her weight to bear down on my steadily-flattening balls. Despite the water in the tub and her arms around my neck taking much of the force off, the pain in my balls started increasing dramatically. I let out a moan and moved my hands from her back to her knee.
"Oh Nat, my balls... My baaaalllllls!"
She looked me in the face, my whimpers obviously making her excited.
"That's right! I'm gunna flatten these stupid nuts! I won't have to worry about you stroking that hard cock if these big things don't work anymore!"
She started breathing heavily and refocused her efforts on her targets.
Fuck, I'm close. That bitchy dirty talk is just too much for me! As I felt myself nearing my climax, I panicked, knowing that once I came, she would get out of the tub and this would be over. Desperate for one last feel, I moved my hands down her back and grabbed her soft, bare ass. She let out an embarrassed squeal, quickly standing up and covering her breasts and crotch again.
"You pervert!" She yelled. "You're getting punished for that!"
Despite what she was saying, it was obvious from the look on her face that she had gotten exactly what she'd wanted. She stepped out of the tub, giving me a clear view of her well-shaped ass, and picked her towel up off of the ground. After she wrapped her towel around herself, she took my clothes from the side of the sink and carried them out the door.
"Nat, what are you doing with my clothes?"
She turned to look at me, brow furrowed, but unable to hide her devious smile.
"Naughty boys who grab their sister's ass need a punishment!"
As she left the room, I panicked. What if we have a visitor?! I can't just walk around naked! In my panic, I jumped out of the tub, drying the bottom of my feet on a floormat, and ran out the door, only to be stopped by a sudden, sharp pain exploding in my crotch.
Smack!
"Gotcha!" Nat yelled, giggling excitedly as her plan had worked flawlessly.
When she'd left the room, she'd hid around the corner, waiting for me to chase her so she could catch me off guard. As soon as she saw me, she launched her foot into my balls, crushing them against my pelvis. I bent over, holding my balls and breathing heavily as I tried to calm the pain. Nat threw my clothes behind her and stood in front of me, her hands on her hips and her body only covered by the towel.
"How'd your balls like that? Did it hurt? You weren't expecting that one!"
As she watched me groaning and holding my nuts, she started bouncing on her tippytoes, unable to contain her excitement anymore.
"Spread your legs! I wanna kick your balls!"
I looked up to see the petite woman bouncing up and down from the exciting prospect of busting my balls. In the midst of this bouncing, the top of her towel started to drop, revealing her hard, pink nipples. As I watched her small, exposed tits bounce up and down, my dick started throbbing. With my eyes glued to her chest, I moved my hands and spread my legs, clearing the way for Nat to do what she did best. She took a breath, calming herself down, before bringing her right leg back.
"You'd better pray I don't pop those big, stupid babymakers of yours!"
Nat sent her foot flying forward, crashing it into my balls and lifting me an inch off the ground as a slapping sound echoed throughout the room. She giggled as I fell to my knees, my hands desperately clutching my throbbing nuts.
"Hands off!" She yelled, kicking my hands away and once again exposing my sack. "This is a punishment! You're not allowed to protect them!"
She reached down and grabbed both of my hands, bringing them up and placing them behind my head.
"Keep your hands up there." She said, licking her lips as her eyes darted down to my completely defenseless dick and balls. "I'm really gunna fuck those balls up today!"
Nat delivered kick after devastating kick to my balls, smashing them up into my pelvis and causing me to cry out in pain each time. As my hands were clasped behind my head and I was on my knees with my legs spread apart, I was unable to do anything to protect my vulnerable nuts. With each subsequent kick, the burning, throbbing pain in my crotch steadily spread throughout my entire lower half. My eyes remained glued to my sister's chest, now completely exposed with the towel barely reaching her ribs. With each kick, the loud smack of her soft foot obliterating my naked balls was matched with the sight of her petite breasts bouncing up and down. After a dozen or so kicks, Nat started to breathe heavily, reaching her right hand under the bottom of her towel and touching her own crotch.
"Ooohhhh..."
She let out a sensual moan, and her body started to tremble. Watching the beautiful, nearly-naked woman pleasure herself after the cruel punishment she'd just delivered to my most sensitive area, I forced myself to stand. I walked up to her, placing my hands on her hips and leaning into her as the excruciating pain in my throbbing, swollen balls was almost too much for me to stand on my own. As she continued to rub herself, I leaned in and whispered in her ear.
"You're not done yet, are you? I thought you'd want more than that."
She let out a gasp at my words, rubbing herself more furiously as she listened intently.
"You're gunna bust my balls some more, right?" I asked, grabbing her free hand and moving it to my swollen ball sack. "I thought you said you were gunna fuck my balls up?
"Ohhhh.... Ahhhh!..."
She wrapped her right hand around my left nut and started squeezing. My body tensed and my hands grasped her hips.
"Oh fuck, Nat! My ball! You're crushing my ball!"
Nat's moaning and gasping became louder, and as she stared down my free nut, she removed her hand from her own crotch and reached for it, freezing between the two. Her eyes darted back and forth, as she was unable to decide between destroying my crotch and pleasuring her own. After a few seconds, I reached my right hand under her towel, gently rubbing her pussy before slowly entering her. She let out a surprised gasp, her blushing face looking up at me in surprise.
"Do it." I told her. "I know you want to squeeze them."
As I slid my fingers further into her, my hand set into a rhythmic motion, and I could feel the wet, warm sensations of my sister's pussy as she frantically reached her now-free hand forward and grabbed my left nut.
"Ahhh!! Ohhhh!!!" She screamed, bucking her hips wildly and biting her lips. "Fuck! FUUCKK! Your balls! I'm gunna destroy your fucking balls!
She clamped down on my swollen balls with all her might, nearly causing me to drop to the floor. I moaned loudly from the pain, using all of my energy to remain standing and continuing to pleasure her with my hand.
"Ohhh! AHHH! Wait! WAAIIT! AAAAHHHHHH!
All at once, her screaming, her moaning, and the bucking of her hips stopped. Her entire body tensed up, and as she continued to squeeze the life out of my throbbing balls, she buried her face in my chest. Her mouth stayed open, but no noise could be heard, and as I slowed the rhythmic movements of my fingers, her body slowly relaxed.
"Mmmmmmmmhhhh...."
She let out a long sigh as she fell into my body. She pushed herself off of me, stumbled over to the couch, and plopped down into a seated position. She let her head fall back into the couch and looked at me, her face completely red, her eyes crossed, and her mouth slightly agape. Taking a few seconds to breathe, she tried to speak.
"You... pervert..." She started, taking ragged breaths between words. "Touching... your sisters... pussy... like that..."
She let out another moan as she fell into a laying position, her towel nowhere near covering her petite breasts. Seeing her in this state and having not cum yet, my entire body trembled. Jesus Christ, I have to fucking cum right now! I started walking toward the staircase but was stopped by the sound of Nat's voice.
"You better not... be going up there... to stroke that cock..."
I looked back to see the dazed brunette forcing herself to stand, picking up her towel and placing it back over her breasts. As her eyes uncrossed and her hazy mind cleared, she looked at me with furrowed brows and pouting lips.
"I didn't know you'd... do something like that..."
Her voice trailed off, and as her face turned a deeper shade of red, her eyes darted around the room, as if she were trying to find the words she wanted to say.
"That cock really is dangerous." She said, looking down at my still-throbbing dick. "It gets so horny that you end up touching your sister's pussy like that... It's a good thing I'm here to keep it under control!"
No, you dumbass, this is all BECAUSE of you! How the fuck don't you SEE that yet?!
"I think it's time for some drastic measures!" She said, one hand leaving her towel and pointing at me as if condemning me of some terrible crime. "No more pants for you!"
What?
"What? What are you-"
"To make sure that cock isn't secretly getting hard," She interrupted, "You can't wear pants anymore. If you're naked, I can keep a better eye on that naughty cock!"
As I stared at my towel-clad sister, I was both amazed by the astounding stupidity of this whole conversation and excited at the prospect of always being exposed and at Nat's mercy. This new fantasy was too much for me in my already-horny state, and my dick started to throb so hard it was painful.
"Okay, okay," I agreed, desperate to go upstairs and relieve myself. "I'll keep my pants off, but I really need to-"
"No! Hands off that naughty cock!"
She walked up to me, reaching out with her right hand and slapping my hard dick in an overhand motion, causing it to bounce up and down. I let out a moan and grabbed her hips, causing her to shoot her knee up into my balls.
Crash!
With this final, devastating knee, I immediately hit my climax, and bucking my hips as hard as I could, I came. My first shot hit the top of her towel, with each subsequent one covering a lower and lower part of the cloth. With each shot, I let out a loud moan, intensely gripping her hips as I tried to stay upright. Nat remained frozen as she watched my twitching dick, her face turning red as she bit her bottom lip. As my orgasm faded, I backed up and slumped into the couch, completely drained of energy. A few seconds later, Nat came to her senses, her brows suddenly furrowing.
"Jeez!" she yelled. "This is what I mean!" She looked down at her now cum-covered towel. "Ew! Why does that stupid cock always have to cum so much?!"
She threw the towel at me, revealing her naked body for a split second before running toward the staircase. She stopped at the bottom, turning to me with her hands again covering both her chest and her crotch.
"I'm serious!" She yelled. "If I catch you trying to cover that cock, I'm gunna smash those balls flat!
With that, she ran up the stairs and out of sight, followed by the sound of her door slamming shut. I continued to sit on the couch for a few minutes, my vision blurry and my mind hazy. I laid down and took a deep breath, my entire body completely relaxed after the relief I'd just experienced. As I sat up, my hands reached down and grabbed my swollen, throbbing balls, rubbing them in an attempt to quell the intense pain radiating through them. I looked at the staircase and thought about what my sister had just said.
No pants... Completely exposed all the time... My heart started to race as I thought of the possibilities. As my mind wandered to fantasies of squeezes, kicks, knees, and God knows what else, my body started to tremble. Oh God, I can't wait! What is my bratty little sister gunna do to me next?!

Bratty sister 9: Watching a video together, and a couple of new firsts
After regaining my strength from Nat's squeezes, kicks, and knees, I'd made my way back upstairs and plopped into my bed, falling asleep almost instantly. I awoke the next morning, feeling groggy and dazed. All this ballbusting is really starting to take its toll on me. It's impossible to get any sleep when my nuts are always swollen! I got out of bed and started to put on my shorts, stopping myself halfway when I remembered what Nat had told me last night. No more pants, huh? I took the shorts back off and looked toward my bedroom door. She's usually here to wake me up. I wonder where she is? I left my room, heading downstairs to find my petite little sister in the kitchen, hunched over in front of the toaster. She was wearing a loose-fitting gray sweatshirt and black short shorts.
"Morning, Nat. What are you doing?"
The thin brunette turned to me, her face beaming when she noticed my entire lower half was exposed.
"Making breakfast! I see you remembered the new rule!"
She skipped over to me as if she was going to jump into my arms, only to swing her hand back and arc it forward, slapping my balls from underneath.
Slap!
"ohhh!"
As I bent over and held my balls, she put her hands on her hips and puffed out her modest chest.
"See? It'll be so much easier to smack those stupid balls around now!" She looked up from her targets to see that my dick had already started to rise. "And it's a good thing, too! You just woke up, and already that big cock is getting hard!"
I braced myself for whatever cruel hit would follow those words, but none came. I looked up to see Nat back at the toaster, clapping excitedly when two Pop-Tarts popped out.
"Here, I made us breakfast!" she proudly exclaimed. "One for you, and one for me! Feel free to compliment the chef!"
You're actually out of your damn mind if you think I'm complimenting you on cooking a Pop-Tart.
I took the pastry, eating it as Nat checked her phone.
"Chloe's gunna be here soon," she said as she scrolled through her text messages. "We're gunna hang out and watch some videos."
Chloe? HERE?
"Wait!" I protested. "I've gotta put some pants on if someone's coming over!"
"Hahaha, what are you talking about?" she responded. "I'm pretty sure Chloe's already seen what you're packin'."
As I tried to come up with an argument that this bratty young woman would understand, I heard a knock on the door. Nat gingerly ran to the door, opening it to reveal Chloe wearing a white tank top and bright purple short shorts. As she cheerfully greeted Nat and walked inside, I could see that she was somewhat sweaty, allowing me to see her black sports bra under her tank top barely containing her massive tits.
"Sorry!" the busty blonde said. "I just finished my morning workout, so I'm still a little sweaty.
"Don't worry about it!" Nat responded.
As the pair walked into the living room, Chloe's eyes immediately darted to me, a devilish smile appearing on her face.
"Well, good morning, Mr. Big Brother! You haven't even said hello, and you've already got that big thing out!"
I quickly moved my hands to cover myself, but Nat ran up and slapped my hands away.
"You know the rules, mister!" she said as she pouted and looked me in the eyes. "Boys with big, naughty cocks don't get to hide! I need to keep an eye on this thing!"
Nat grabbed both of us by the wrists, dragging us to the couch and making us sit down. She put me in the middle, with Chloe seated on my left and herself on my right. She pulled her phone out, clicking the Bluetooth button and syncing it to our TV, then started typing.
"Sorry about this." I apologized, looking at Chloe to find her not looking at my face but at my crotch.
"It's Okay. She's been really going at it lately. I already expected you to have your cock out at some point during the visit.
"Is it really such a routine thing now?"
"It really is."
We both laughed as we joked about the absurd situations that my little sister had been dragging us both into when we heard Nat yell.
"Here it is!" she said, pointing at the screen that was now casting a video from her phone. "This new video I found! It's so good!
Both Chloe and I turned to the TV, seeing a naked man seated on the ground with a hot leather-clad woman standing over him. Oh my god, Nat! We have a visitor! Have a bit of shame! Nat put her phone down, scooting up beside me and laying her head on my shoulder. As she started bouncing her feet on the ground in excitement, I reached over and paused the video.
"Nat, Chloe's here! What are you doing putting this stuff on the TV?!"
Nat looked over at me and pouted.
"Really? You're gunna act like that after you played with my pussy last night?"
I froze, unable to respond. Why the fuck would you say that?! I turned to Chloe, who was looking up at me, blushing and covering her mouth.
"Mr. Big Brother... I had no idea..."
"No listed, I can explain!"
"It's one thing to go around getting girls to kick your balls, but stuff like that with your sister..."
Smack!
"Ohhh!"
Our conversation had been interrupted by the sound of Nat roughly slapping my nuts, causing me to reach down and hold them as she un-paused the video.
"Seriously guys, this video is really good. Stop interrupting!"
Both Chloe and I turned our attention to the screen, watching as the leather-clad woman took off her platform boots. As the camera zoomed in on her bare feet, she walked closer to the man, stopping only an inch from his exposed balls. Wait, this video might actually be good. I watched intently as the woman stepped up with her right foot, gently resting in on the man's left ball. The camera zoomed out, and the woman placed her hands on the man's shoulders, preparing to balance herself. I felt Nat cuddle up to me and wrap her arms around my right arm. Once the woman on the screen had her balance, she brought her left foot onto the man's right ball, placing the entirety of her weight on the man's vulnerable ballsack. As the man on the TV started moaning and begging for her to stop, my sister and I started to breathe heavily. Chloe looked over at us and then down at my crotch.
"He's already hard!" Chloe said, reaching down and grabbing my dick at the base.
Nat looked down and started giggling. "That's why he has to be naked! You never know when that stupid cock is gunna get hard!"
Nat reached down, lightly slapping my balls as she cuddled up closer to me and looked back at the screen.
"Chloe, keep an eye on his cock. We need to make sure he doesn't cum all over the place."
With this, Nat started rhythmically slapping my nuts as she watched the screen intently, an excited shiver running down her spine as she watched the man on screen scream and beg for mercy. I felt Chloe's hand move up the length of my erection. As she brought her free hand to grab the base of my dick, she leaned in to whisper in my ear as her massive tits pressed into my chest. Her words were so soft that only I could hear them.
"She still doesn't know that you like this, huh?"
I wrapped my arm around her back, leaning in to whisper back to her. As I closed in, I could smell the faint scent of her sweat and the fragrance of her shampoo. I got so close that my lips barely touched her ear as I spoke.
"No. I don't know how she would react. Maybe if we could still keep it a secret?"
She adjusted again, leaning into my ear. The words I expected never came, and instead all I heard was the gentle sound of Chloe blowing into my ear. My body tensed from the stimulation, only for me to be brought back to reality by a sudden hard slap from Nat.
Smack!!
"Ah, Nat!"
"Did you see that?!" she yelled, kicking her feet in excitement.
As she kicked her feet, her foot hit the bottom of the couch, causing her phone to slide off and land on the floor and the video to start buffering. She removed her hand from my crotch, jumping down to get her phone and desperately trying to resume the video. She looked up at us, a genuine sadness on her face.
"I can't get it to work now..." she said, her eyes cast to the floor.
"It's okay!" Chloe responded, desperate to cheer her best friend up as both her hands were still wrapped around my erection. "You have a couple of balls to play with right here!" She moved her hands down and roughly grabbed my nuts, causing me to flinch.
"Chloe, could you..." Nat trailed off.
"Could I what?"
"Could you bust him for me?"
Chloe, obviously confused, tilted her head as she stared at the petite brunette.
"Are you sure, Nat? I never thought you'd pass up a chance to crack his nuts!"
"I really had my hopes up to watch the video. I could watch you instead. Maybe that would be almost as good."
Chloe started giggling as she moved off the couch, sitting on her knees between my spread legs as she roughly grabbed my balls with her left hand and pulled her right hand back.
"I guess I can do it! I can't exactly say no when you look so sad about it!"
Nat started giggling as she moved back onto the couch, snuggling up against me, resting her head on my shoulder as she stared down at my crotch.
"Do it! Crack his nuts! Teach that naughty cock a lesson!"
Nat, what kind of situation is this?!
As Chloe delivered her first punch, I threw my head back and groaned. Nat giggled and wrapped her arms around my body, squeezing me tight as she watched Chloe's assault intently. Chloe continued to bring her fist back, driving it into my completely defenseless balls over and over. Unable to protect myself and my mind screaming for the pain to stop, I desperately grabbed onto Nat, squeezing her tight and resting my forehead on hers. She gasped in excitement, reaching down and grabbing my dick with her right hand.
"This is what you get!" she panted, continuing to watch the busty blonde wreck havoc on my poor nuts. "This is what happens to boys with big, naughty cocks!" She squeezed my dick, causing me to latch onto her more tightly.
"Nat! NAT! FUCK! My balls, My BALLS!"
Both of us looked back down, watching Chloe release my balls and stand up, wiping the sweat off her forehead.
"Jeez, these nuts can really take a beating!"
"How about some kicks? Chloe, kick his nuts for me!"
I scooted myself forward, allowing my throbbing balls to hang off the edge of the couch. I looked Chloe in the eyes, silently begging her for more punishment. Chloe gave me a knowing smile, bringing her right foot back before launching it into my nuts.
SMACK!
As Chloe delivered kick after kick, I could feel Nat's hips start the rhythmic bucking that I'd become so accustomed to. I looked over at her, our eyes meeting as she started biting her bottom lip. I leaned in, whispering to her.
"Nat, my nuts... She's gunna... break my nuts..."
Nat gasped, her hand immediately darting down to her own crotch but freezing mere inches away. She stared into my eyes for a second, then moved her right hand to my dick, squeezing it tightly as she slowly opened her legs. Unable to control myself, I wrapped my arm around her, bringing my hand to her crotch and gently sliding my it into her panties. She moaned softly as my fingers effortlessly entered her warm, wet pussy. As she moaned and her body trembled, she started running her hand up and down the length of my erection, causing me to moan in unison with her. Nat leaned in and rested her head on my shoulder, and I looked up to see that Chloe was watching us pleasure each other, her face beat-red. After a few seconds of watching us, she continued her cruel kicks.
After the fifteenth kick, I started bucking my hips, unable to contain myself anymore. As I neared my climax, I redoubled my efforts on pleasuring my sisters pussy, quickly bringing her to climax as well. As she screamed and threw her head back, I moaned loudly and bucked my hips a final time. As I came, I shot high into the air, completely covering Chloe's face and chest. Chloe yelped in surprise, backing away from us as Nat and I slumped into the couch, our eyes crossed and our breathing ragged. Nat snuggled up to me, looking like she was about to faint. When my vision cleared, I looked up to see Chloe staring at us, her cheeks a deep crimson and her face and chest covered in my cum.
"U-um..." I stammered, trying to think of an explanation for everything the busty blonde had just witnessed.
"Wow, you really do touch her there, don't you?"
"W-Well you see-"
"I need to go clean up!" Chloe interrupted, running to the front door. "I'll go home and change! We'll hang out next time!"
Wow. I haven't seen her that embarrassed since the first time we met.
As Chloe left and slammed the front door shut, I looked down at my sister. Nat was lying on my arm, still breathing heavily with her eyes crossed and her mouth agape.
"Nat, you okay?"
"Ohhh... Ohhhhh...."
Wow, she must have really liked that.
As I tried to get up, she clung to my arm. I looked over to see her slowly moving to me, her eyes finally uncrossing. She leaned in before I could say anything, giving me a gentle kiss on the lips before quickly turning away.
H-huh?!
"T-that's for always letting me have fun with your balls..."
Though I could not see her face, the deep red shade on the top of her ears told me that she was blushing heavily.
"You know I like busting your balls now. It's embarrassing, but..."
What the hell is this?! She's never been this direct before!
"T-Thanks!" she yelled, quickly getting up and running to the staircase.
This is getting complicated. A handjob and a kiss... I stood up, still exposed from the waist down, and returned to my room, laying on the bed and letting out a drawn-out sigh. I pondered what I would say to Nat the next time I saw her. She roughs my balls up constantly and sees me naked more often than clothed, but this is just... different... My thoughts trailed off. A few minutes later, I remembered Chloe's embarrassment at the whole situation. Shit! I gotta figure out what to say to her too! I got back under the covers, deciding a quick nap might help the creative juices flow. I drifted off, contemplating how to handle the future with my bratty little sister.
