Both my hands are broken, I can't jack off, and my sister is assigned as my caregiver.

All characters are at least 18 years old.

I fell off my skateboard and shattered bones in most of my fingers. Now I can't even do the most basic shit for myself. Worst of all, I can't jack off.

Mom was away on business, so my sister, Zoe, has been helping me out with the daily grind. She never complained when she did things like feed me or brush my teeth. I'd thank her and she'd hug me and say, "No problem, bro."

I've always known that my sister was a knockout, but with me unable to shoot my wad, it's harder than ever to stifle sexual thoughts of her. She's got these full, round tits and a perfectly shaped ass that sticks right out. All that combined with her lovingly helping me every day, it was like the universe conspired to make me wanna fuck my own sister's brain's out.

The moment of truth came when she had to give me a shower for the first time. Zoe was dressed in nothing but a skimpy bra and cheeky panties. My sister was trying not to look at me too much. She turned on the shower, avoiding the spray at first, but then her ungainly tits got soaked. Her lips pursed in frustration.

I sat on the edge of a shower bench. My sister bent over to push soap scum down the drain. I got a full view of her masterpiece of an ass in soaked panties. My dick rapidly hardened. I was filled with absolute horror as my dick got so hard that it pulsated at Zoe's ass, begging for her.

Zoe straightened up and turned around. Her eyes darted downward, and she saw her brother's pleading monster. She gasped, a blush creeping up her neck and over her cheeks. She looked away. "Andy, what the hell?" she said, her voice crackling with the tension in the room.

"I'm so sorry, Zoe, I just can't help it. It's been weeks since I could, you know, cum, and I'm just really sorry."

Zoe sat next to me on the bench, still averting her eyes. "I get it, Andy." she sighed. "I can't imagine how uncomfortable it must be that you can't have release, but I just can't give my brother a shower while his big hard dick is jittering at me."

"That's okay. I can't get rid of it though. I'll just have to stink."

Zoe looked at me with pity. "That'd be unfair to you," she said, her voice low and serious. "I have an idea, but I'll only go through with it if it's cool with you."

"Sure, what is it, Zoe?"

"Well, my friend, Trina, had this problem with her brother. Their family would go to the beach, and he would see her in a bikini, and you know, pitch a tent in his trunks. To get rid of it, she'd squeezed his balls."

My stomach dropped. "Fuck."

"Again, totally up to you, and I would prefer if you squeezed your own balls."

"Zoe, I can't squeeze my own balls. That would be like trying to choke myself to death."

My sister glanced at my balls, which were even bigger than usual from being so pen up with cum. "I guess I could smack them. Would that be okay?"

The thought of that freaked me out, but I couldn't have my sister thinking I was a pussy. She was making such an effort for me, so I should too. "Sure, you could try it."

Zoe took a deep breath and held her hand a foot above my balls. "Ready?"

I leaned back and spread my legs. "Ready."

Zoe's hand hovered for a moment before she brought it down with a swift smack. I felt the devastating pain of her hand sinking into the nut meat, crashing into my balls of nerves, like a sledgehammer to my male soul.

I bit my lip to keep from screaming, the pain sharp and intense. My erection didn't budge.

"Again?"

Against all my instincts, I nodded.

She smacked them again, this time harder. I could feel her hand press even closer to the core of my nuts. The sting grew stronger, but my dick remained stubbornly determined.

Zoe asked, "Want me to just keep going until it goes down?"

With my teeth grinding, I groaned, "That's fine. I can take it."

"Alright, try to breathe through it."

Zoe's hand hovered over my balls again, her eyes searching for the perfect angle to strike. The anticipation was almost worse than the actual hit. But when it came, I couldn't hold back a sharp intake of breath. The pain shot through my balls like lightning, up my spine, making my entire body tense. Still, my erection held firm.

Her expression was a mix of woe and determination. Zoe even squeezed her own crotch in sympathy. With her other hand, she just kept smacking them, again and again, her tits jiggling with every swing.

Every hit brought a new wave of agony, but my dick didn't seem to be getting the message. It remained rock hard, shaking like an unstable flagpole. The pain was indescribable. It eventually felt like her soft hand was a metal bat. I couldn't believe how fast my balls swelled and how much pain seeped to the rest of my body.

Zoe seemed to lose herself in the ballbusting, like it was an absolute thrill to her on a subconscious level. This would confirm what many guys at school said, which is that females innately get pleasure from busting guys' balls, whether they're consciously aware of it or not. That would explain why it was so common for the girls at school to kick guys in the nuts, even for just glancing at their tits or politely asking them out.

Zoe finally stopped smacking my balls as she seemed out of breath. Even still, the agony kept building within my sack and torso. I could barely breathe.

She got a close look at my dick as she seemed to be struggling to believe its resilience. My sister's jaw dropped at the sight of my completely unfazed dick.

Her wide open mouth was only a few inches from the head. I so badly wanted to shove my whole cock through her lips and onto her tongue, and grab her ears, and fuck her face. My aching need added even more pain to my balls. With her gaping mouth so close, my cock jittered harder than ever, which made my sister flinch back.

Catching her breath, she said, "Maybe I just have to do what my friend did and squeeze them. Would that be okay?"

I had an unhealthy need to impress my sister. I nodded.

Her small hand was barely able to get a good grip on my swollen balls. It was so weird and oddly sexual feeling and seeing my sister hold my balls. She began by squeezing gently. Her subtle pressure inflamed my already battered nut nerves. Slowly, she tightened her squeeze.

The pain grew steadily, like a crescendo of agony that made every muscle in my body tense up. Her hand changed my balls' shape like she was holding a pair of water balloons. It was hopeless to try to keep my face straight. I felt ashamed that my cock would still not relent, ashamed to have something to sensitive and weak as balls, ashamed to be part of the male gender with our amoral lust.

Zoe's grip tightened even further, her feminine hand sinking deep into my fragile masculinity. The pain was so intense that my vision swam and my thoughts were drowned out by the pulsing agony. My dick continued betraying me, pulsating despite the torture my beloved sister was administering to my nuts.

Continuing to squeeze harder, Zoe bit her bottom lip and her eyes closed. She seemed lost in the pleasure of both feeling my nuts and dominating my manhood.

Barely able to speak, I croaked, "Stop. Please stop."

She let go and stepped away from me. "Oh my gosh. I'm so sorry. I lost myself there for a minute."

I muttered, "It's okay."

She got on her knees between my legs, perplexed by the sight of my unwavering cock. "Wow, all that had no effect on your thing. Your need to release must be so unbearable."

I whimpered, "It is."

She took a deep and sad breath. "I'm sorry, Andy. I've been trying to take care of you, but I failed to take take into account one of your most important needs."

She gently wrapped her hand around my cock and began pumping. The shock and pleasure of it hit me like a truck. I flinched and gasped.

She said, "I know this is so fucked up, but you really need to cum."

I groaned, "Thank you, Zoe."

"I just hope I can do well. I've never done anything even remotely like this."

"Y-you're doing g-great."

She really was. Her grip became firm. She started to stroke up and down, her thump going in circles on my shaft. Each stroke sent a jolt of pleasure through me, so intense and forbidden it was almost painful, like the sweetest agony.

My muscles tightened as her hand would now cover the head on its way up and down. Zoe was doing something she had no right doing to her own brother, yet she was doing it with such focus and care, like a nurse and a girlfriend at the same time.

She looked at me, her eyes a mix of fascination and delight. "I know this is weird to point out, but you're so big, Andy. I had no idea."

That made me smile even with all the pain in my balls.

Zoe's handiwork improved as she went, finding new sensual ways to drive me crazy. She increased her speed and gripped tighter, determined to give her beloved brother release. She was really giving it her all.

But as much as I was having the time of my life, the pain in my nuts was like a dam holding back my cum. I could feel the pleasure building, but it was like it hit a wall every time it was on the verge of climaxing. It was frustrating to be so close to release and not have it, but I was grateful that it made the hand-job last. Without my nut pain, I'm sure I would've spewed the second she touched my dick.

She said, "I really shouldn't have been so rough with your balls. It seems like that's what's keeping you from cumming. Let me try a different way."

Zoe let go of my dick. She turned around and bent over, her perfect ass right in my face. "You think my butt might help? Is it a good butt?"

"I know I'm not supposed to compliment my own sister this way, but it's honestly the best butt ever, and guys at school like to annoy me with that fact."

She blushed and tried to stifle a smile. "Aww." She wiggled her cheeks as she pulled up her cheeky panties, turning them into a thong.

My cock, still painfully hard, twitched in anticipation. My sister then sat on my lap, my dick nestling between her cheeks. Those plump cheeks clenched, like another loving hug from my sister. She grabbed my thighs and gyrated in the most heavenly ways.

Her movements became faster and harder as she used her dance team skills to go wild on my dick. An intense expression of pleasure took over my face. She looked over her shoulder and smiled at me.

Several times, her ass brought me right to the brink of orgasm. The pain in my balls was still just enough to block it.

She said, "This isn't gonna work either. It's time we took this to the next level."

Like my sister was my own personal fuck doll, I leaned her forward, pulled her panties to the side, and then thrust my dick into her pussy. The warmth and tightness shocked me. We both gasped, filling our lungs.

With one broken hand trying to hold her hip and one broken hand trying to pull her shoulder, I fucked her hard and fast. She moaned and moaned. I kept fucking deeper, and she kept moaning louder. I could feel her walls clenching tighter like she was trying to crush my dick. She was having an orgasm and I could feel her juices spilling. My pleasure built and built and the dam broke. It felt like I was about to spew a gallon of cum.

My sister moaned, "I meant giving you a blowjob, you fucken sicko! I'm not on birth control!"

Zoe reached between our legs, grabbed my balls, and squeezed so hard it made her previous nut-squeeze seem gentle. Her fingers and palm dug in so deep it felt like at any moment my balls could pop. The crushing agony made me silently scream. My arms writhed.

Zoe stood up, abandoning my dick. She turned around to face me, twisting my balls as she maintained her grip. She was so full of rage that she was completely focused on squeezing my balls as hard as she could. She didn't even seem to notice as my dick spewed like an out of control fire hose, getting all over her thighs, crotch, stomach, tits, and face.

My sister twisted my balls. She tugged my balls. She ground her thumb across my poor swollen balls. Zoe was relentless. "Maybe I should rip them off to free you from your male curse of lust and weakness." She put her full effort into every yank and shake of my nuts as she grunted loud every time.

I eventually went limp. My ass stayed on the shower bench as my head fell back onto the floor. Zoe tugged so hard on my balls that she lifted my ass off the bench each time. Through all of this, my dick still spewed. The accumulated nut-pain became so intense that it overwhelmed my brain. I shutdown.

I woke up naked on my bed under a blanket. The pain in my nuts was still horrible, but much less so. More than anything, I still had the painful urge to have a real orgasm. My dick was still pulsating with need.

I looked to my left and was surprised to see my mom. She stood in black bra and panties. She looked like a 40-year-old version of my sister with even more plump tits and ass, and I have to admit, in that moment, I wanted to fuck her just as bad, if not more.

I groaned, "Mom?"

Mom said, "Yeah, I'm back. One of my colleagues tried to kiss me, so I kneed him in the balls, and my boss said she was cool with canceling the rest of the practicum."

"Why are you in your underwear?"

"Well, I heard about what happened with your sister."

I buried half my face in the pillow and moaned, "Oh my god."

"Don't worry, I understand your male needs, and your sister forgives you."

She does?"

"Of course. It was just a misunderstanding in the heat of the moment." Mom ripped the blanket off me.

"Fuck!" My broken hands failed to cover my erection.

"It's alright. I'm gonna help you cum. I can't imagine how much more sexually frustrated you feel after that ruined orgasm."

I was in shock in the best way. "Are you sure you're okay with that?" I asked as I moved my hands away from my dick.

"Of course. It's just maintenance moms sometimes have to do for their sons in these situations."

She grabbed my dick and pumped with such exquisite skill. I couldn't believe the sight of my mom jacking my dick, and how incredible it felt. Her hand job went on and on, and in a way, I didn't want it to end. Due to my still agonized nuts, I still couldn't cum.

Mom said, "Seems like your balls are still in too much pain. I'll try grinding you, but you can't go inside, alright?"

"No problem, thanks mom."

Mom straddled me. She began grinding her panty-clad pussy on the underside of my cock. Her hands caressed my chest.

"Oh god, thanks so much, mom. This feels so good."

She smile wide and said, "Glad you're enjoying it, hon."

I could feel her heat through the fabric. My mom's movements made me think she had a past as a stripper. I loved it. The smooth grind was incredible, and my dick felt like it was on fire with pleasure. But the pain in my balls remained a constant throb.

Mom seemed to be trying to act as if she wasn't enjoying it. Little by little, her panties became drenched. She moaned deeply, her eyes closed as she increased the speed of her rhythm.

Mom's moans grew louder as she ground down on me, her breaths coming in short pants. "Oh, yes, hon," she murmured, her voice filled with passionate need. I could feel the wetness seeping through the fabric onto my cock. Her pussy was begging for me, and the thought made me even more desperate to cum.

My own perfect 10 mother was getting off on me, and it was making me feel like a fucking god. Her movements grew more erratic, her hips pumping swiftly. She took off her bra, freeing her perfect jiggling mounds of womanhood. I could see her orgasm fill her face with a new level of bliss. Her juices drenched my cock. I was so close, but my nut pain was still too much.

Her head fell back in pleasure as she moaned. Her pussy gyrated like a machine through to the end of her long blissful orgasm.

Mom lowered on top of me, her tits pressing into my chest. We held each other for a while and it was wonderful, despite my nut-pain and even more unbearable need to cum.

Mom slithered around and faced my pulsating dick with her knees on the bed, while I got a full view of her ass. "Hm, how am I gonna make you cum. Oh well, desperate times."

Her mouth opened and took the head of my cock in. Her tongue danced around the tip like she was savoring a delicious ice cream. The sensation was heavenly. She licked and kissed it as she often wiggled her ass and pussy at me.

Mom's hand wrapped around the base of my shaft as she took more of my cock into her mouth. It was like she had been doing this her whole life. The way her mouth and hand moved together was pure art. Her tongue swirled around me, and she took me deeper until I was down her throat.

She began to bob up and down, the sounds of her saliva mixing with my moans filling the room. I played with her cheeks and kissed them. The pressure in my balls was building, but as this went on and on, I still could not quite cum.

Mom took her mouth off my dick just long enough to shout, "Zoe! It turns out I do need your help!"

A minute later, Zoe arrived in nothing but a pink thong. With her Lucious tits bouncing, she ran over to my bedside full of excitement, gave me a kiss on the forehead, and then joined our mom in giving me the best blowjob ever.

I played with both of those asses and took turns kissing each of them. Their tongues and lips were almost too pleasurable.

Zoe whispered, "We're gonna make you come so hard."

Mom nodded. "We're here for you, hon."

Zoe's lips were soft, her tongue flickering around my swollen head, while Mom's lips were tight as she sucked and licked my shaft. They worked in perfect harmony, a symphony of pleasure.

Their heads bobbed together, as they both took turns to swallow as much of my cock as they could. They worked me like a pair of experts, sucking and stroking in unison, until I couldn't hold it in anymore. I finally came in an eruption of cum as they took turns sucking it out.

The pent-up pressure in my balls finally burst through the dam. I roared as I shot my cum into their throats, each spurt feeling like a weight off my balls, like a torrent of ecstasy through my dick. They kept it going through every last drop.

My mother smiled at me and said, "There you go, all better now."

Zoe pulled her mouth off, a string of my cum connecting her lips to the tip of my cock. "I'm so glad your better now, bro."

As they cleaned me up, we all laughed, a little nervously. We had just crossed a line that could never be uncrossed, but somehow, it didn't feel wrong.

Even after my hands healed, we were always happy to take care of each other when in need.
