A Painful Vacation with my Little Step-Sister

All characters in this story are at least 18 years old.

A while ago, my little spoiled brat of a step-sister Lea turned 18. I was already 22 at this time. For months, she had been talking about that trip she wanted to do with her best friends. Being the last of her friends group to become an adult, she felt like her birthday was a great occasion to plan it, finally.

Her dad, however, was rather protective about her. I heard the arguing and yelling from the living room a few days after her birthday. When my step-dad called me, I already had an idea that this was turning out to be bad for me. My step-sister stared at me through narrowed eyes with an angry expression when I entered the room.

"Paul, I would like you to join your sister on her vacation and take care of her." I sighted and threw an annoyed glance at her, hoping that she would not be a bitch with me because of this - as this clearly wasn't my first choice of spending my vacation days.

"Can't Lea take care of herself?" I complained.

"Paul, I'm serious. It's not only about protecting her, but also about enforcing the rules she still has to play by. No alcohol, no male visitors after 6, no going out after 9. I'll make you a list and you..." he addressed Lea as strictly as he was able to. "... will play by his rules. Understood?"

Two weeks later, I found myself squeezed in between two of her friends in the back of the car. I had to admit that so far, it wasn't half bad. Lea had very hot and cute friends, rather fun to hang out with, actually. Amber and Ashley who sat at either side of me were almost as tall as I was, with blonde hair and very sexy physiques with round, huge tits.

Liz on the front passenger seat was much smaller, with perky tits, red curly hair and freckles. While she fell a lot more under the "cute" category, she had actually been doing kickboxing most of her life and notoriously lost her temper in certain occasions.

My step sis Lea, who drove the car was somewhere in between "hot" and "cute". A pretty face, long dark hair and green eyes that I figured could actually be quite enchanting for anyone, who didn't know what a spoiled brat she really was.

"Paul, I will drop you off at the grocery store with a list of drinks. Buy them for us." Lea didn't even bother making this request a question. If she had, I would have actually considered allowing them some small drinks despite the strict rule.

"If you ask me nicely and say please, I may get each of you a beer or two for the week." I said strictly. Lea's green eyes met mine in the mirror for a moment. While I expected her to have this typical annoyed expression that she always had when she didn't get what she wanted right away, she was actually smiling.

"Amber, would you be so kind, please?" she purred in the nicest tone I've ever heard from her. I turned my face to the right and met Amber's much wider smile.

"Gladly." she grinned. I noticed a fast motion in front of me. When my eyes darted down to see what was going on, it was already too late. With decent speed, Amber's open palm raced up in between my legs. Instinctively, I tried to close them, but all I did was releasing the tension of my shorts in between my spread legs. Just when the stretched cotton became soft and unprotective, Amber's hand accurately smashed into my balls and instantly got a good grip on them.

"Ooouuuggghhh" I moaned from the sudden, sharp pain in my sensitive genitals. Amber's long fingers enclosing my most vulnerable and precious possession elicited a sudden rush of fear and defeat. The excited, girlish giggle that instantly followed from all around me, made me blush instantly. While my hands desperately began tapping the wrist of the punishing female hand, I threw a glance at my sister through the mirror, silently begging for mercy. The sadistic malicious joy in her eyes actually scared me.

"I think, you can go a bit harder." Lea smirked, visibly enjoying the rush of power.

"Oh yeah, you can for sure. May I?" Liz turned around in the passenger seat and grinned at me with a sadistic joy that made the blood in my veins freeze. Stuck in the confined space of the car with four girls around me who showed a sudden joy in torturing my weak manhood, I panicked.

"Please, don't...", I begged. "I will buy anything for y..." just as I wanted to give in to my sister's request, Amber lifted her hand with mine still softly holding on to her wrist. A split second later, Liz's hand darted through my still slightly opened legs incredibly fast. The impact and following hard squeeze instantly put me down. While Amber had been somewhat tender, Liz's small hand was absolutely punishing.

"That's more like it." my sister laughed out loudly, as my forehead almost bumped on the handbrake next to her. I could feel her hand tousle my hair while Liz continued compressing my nuts like a screw clamp.

The redhead bitch continued squeezing my nuts while my sister drove us to the grocery store. Her hand actually moved around to explore my groin and get a better grip. When she found my dick in between the shorts and my thigh, she grabbed it along with my balls, pressing them together while slightly grinding up and down its shaft.

When I finally got out of the car in front of the grocery store, I had a massive boner, my testicles ached like never before in my life and the girls were hysterically laughing at my misfortune induced by them. With a bright red face, I stormed into the store and got them all the liquor they wanted. Of course, I had to pay for it.

After loading everything into the trunk, I approached Ashley's side to get back to my place. Upon opening the door, Ashley just stayed on her seat and smiled at me. Usually I would've been more than happy to climb over her sexy legs, mostly bare under the short skirt she was wearing.

"Get in Paul, now!" I heard Lea's impatient voice. Sighing, I cupped my still aching balls with my left hand and carefully began climbing through the narrow space. When I was just on top of Ashley, facing her, I heard the clicking of a car seat being readjusted. The following rough shove in my rear made me lose balance. My free hand, desperate to find halt, accidentally grabbed Ashley's amazing tit.

The wonderful feeling was quickly overshadowed by the fear of consequences. Instinctively, I moved up my left hand to push myself away from her by the seat. The moment, I found support with my left and let go off her soft tit, her pointy knee shot up right in between my widely opened thighs.

Her kneecap caught my nuts dead-on and flattened them against my pelvis very briefly. The brutal and defeating pain instantly took all strength out of my body. With a stupid sounding shriek, my knees gave in and I landed right on top of her thigh, squeezing my balls with my own body weight.

It took me a moment to realize that my face had come down right on her boobs. Ashley was giggling so hard that they bounced and jiggled playfully.

"Get off me, pervert." she blurted out in between laughs, but it was obvious that she was having a lot of fun right now. With my balls still stuck in agony between her bare thigh and my pelvis, and the little room, I had between the driver's seat and her, there was nothing, my weak body could do.

After another seemingly endless couple of seconds in absolute pain and helplessness, one of the other girls grabbed my shorts above my butt and yanked it up and over to my seat. While the tension of my pants inflicted another terribly painful pinch in my testicles, I was actually grateful for the support and help.

The remaining hour or so of the drive, I sunk into my seat as small and inconspicuously as I could make myself. Cupping and nursing my relentlessly aching nuts, I tried to escape the shame and embarrassment of my unfavorable male weakness being such a wild fun for my sister and her friends.

They did leave me alone, but quickly started talking about a movie they had watched the previous night - 'Birds of Prey'. I didn't know it, but from the excited girls I learned that apparently the main character, Harley Quinn, kicked dozens of guys in the nuts in that movie.

The verbal mix of female curiosity, visible excitement, entertainment and Liz' "professional" view on busting balls made me want to sink into the ground. Clutching my weak spot with both hands, I quietly listened and suffered, knowing that I would have to deal with this for over a week.

When we arrived at the small, remote house at the lake, the girls rushed inside to choose their bedrooms. The cottage had three rooms with a double-bed each, so it was set that I had a room for myself. No one told me to, but I just went ahead hauling the stuff inside.

It was probably a good idea to stay on good terms with the girls, despite what had happened. After locking the car and bringing the last bag inside, I realized that my bag had disappeared from the pile. Sighing, I walked to the first of the bedrooms and pushed the door open.

Liz stood in the center of the room, facing away from me. In front of her on the bed, she had her bikini prepared. The moment, I laid eyes on her, she bent down and slipped off her panties, leaving her fully in the nude. She had an absolutely amazing butt, with a pair of long, muscular, visibly powerful legs below. For a very short moment, when she was bent all the way down, I got a glimpse of her freshly waxed or shaven pussy.

Equally delighted and panicking, I tried to grab the handle of the door that continued swinging open, but I had been stunned by the impression long enough for it to escape my range. When the gush of wind from the door manifested in Liz' bright red hair, I knew that it was too late. The girl that had spent the last hour talking about the art of "accidentally" kicking guys in her MA class in the balls, turned around to face me with an expression of pure danger.

She didn't even look angry or embarrassed. Neither did she try to cover her perky B-size tits or hairless pussy when she saw me in the door frame. Instead, she glanced at me like a tiger about to jump his prey. I wondered, how many guys had seen this expression on her in the classes, shortly before rolling around on the floor, defeated by the unimaginable pain in their flattened testicles.

I saw it coming from miles away. I knew that I should probably have tried to defend myself. But having that amazing redhead cutie in front of me, full frontal nude, I still couldn't think or move. Probably, it would only have made it worse, anyway.

With a rapid, wide stride, Liz covered the ground in between us and launched her leg up in a long arc. Her small foot accurately found my groin and wreaked absolute havoc there. In the moment, the nude girl mercilessly flattened my balls, I couldn't help looking at her smooth pussy in envy.

I couldn't believe how unfair it was, when my muscular, huge body was rendered fully useless by the one swift kick in the crotch. My knees, then forehead landed on the carpet, before I fell to the side and rolled into a small ball. The nude girl raised her fists in a power pose, even spreading her legs a bit. Unfortunately, the raging agony burning in my balls and radiating up my stomach left me incapable of really enjoying the view from my position.

"You're really asking for it, aren't you?" Liz grinned, visibly high from an obvious sexual rush of effortlessly defeating a much larger and stronger male by kicking him in his sexual organs. Giggling, she went back to putting on her red bikini top, very slowly and somewhat sensually. I couldn't take my eyes off her while kicking my legs in a fruitless attempt to ease the throbbing pain.

When Liz attempted to put on her bikini bottom, she hesitated. Swiftly, her hand slid in between her legs, and she opened her mouth in a very faint moan. The aroused girl was so beautiful to look at. Suddenly, she sat down on the edge of the bed, her legs spread. I couldn't believe that I was allowed to see this. Unfortunately, I wasn't.

"Now fuck off. When I open my eyes and see you, I'll break your balls - no matter if your sis allows it." Her threat was quite humiliating. Somehow, my testicles had become my sister's property for this vacation. Liz, however, fucking scared me. She was so dangerous and cruel that I didn't consider this an empty thread for a second.

I forced myself on all fours and crawled out of the room backwards, pulling the door with me. Although the pain in my nuts had barely decreased, I had a raging boner that made my cotton shorts even more uncomfortable.

I simply couldn't stop thinking about Liz' amazing nude body and her cruel way of defeating me in the most sexual way there was. The joy she was obviously getting from it, approaching her orgasm right now while I still couldn't get to my feet, given the relentless ball-ache she gave me. Somehow, it all turned me on.

It was the fear of being caught like this by any of the other girls that finally made me get to my feet. I just wanted to get my bag and hide in my room to jerk off until the girls' excitement about my natural weakness possibly ebbed off a bit. My heart was racing in my chest, when I stood in front of the second door. This time, I knocked.

"Come in!" I heard my sister's voice. Reluctantly, I opened the door. Lea sat on the edge of the bed, just like Liz when I left her. She was wearing a black, very short bikini and had one leg placed over the other, her right bare foot wiggling up and down rhythmically.

Behind her on the bed was my opened bag. The disrespect for my privacy made me annoyed, but the ache in my balls reminded me of not openly showing that. I stepped up to her and made sure to stay out of the range of her foot.

"Is this my room?" I quickly asked. Her narrowing eyes were a bad sign. Whatever bullshit she was up to, I really didn't want to deal with it now. Actually, I might have been a bit angry from being rejected by Liz, after it was kicking my balls, that made her horny in the first place.

"First, we have to discuss the rules, Paul.", my step sis said patiently.

"Fuck the rules, do whatever you wish. What else do you want?"

"Oh, I'm not talking about your rules. I'm talking about mine!" A mean smirk formed on her face, as she watched my anger rapidly increasing.

"Fuck you! Now get out of my room." I knew that she was going to try and kick me in the balls, so I went a step back and placed my hands on my hip, pointing inward right next to my groin in order to be ready for a block.

Lea simply giggled at my obvious attempt to protect my testicles from her. Suddenly, she lifted her hand, locked her index finger with her thumb and - closing one eye - aimed her hand at my groin as if she could flick it from that distance. In the moment, she flicked her finger, I actually twitched a bit and instantly felt stupid.

A split second later, I felt even more stupid, when something shot up between my legs from behind with high speed. I looked down just in time to see the top of a bare foot with painted nails smash into the bulge between my legs. With my cock still half-erect and close to my left pocket at the side, my swollen, aching balls absorbed all the force of the surprise kick.

My eyes bulged out and I let out a shocked squeak. My step-sister's triumphant grin hurt nearly as much as the wave of agony washing over my body from its center. The way she had turned me into a toy for her girlfriends' naughty fun was extremely degrading. The way she underlined it with her sexy, forbidden body in that skimpy bikini made it even worse.

Before I could fall onto my knees, the tall two blondes appeared behind me from either side of the door and grabbed my arms. I instantly felt that both of them had changed to bikinis, too, as they pressed my arms closely against their mostly naked bodies. Another moment, that could have been very enjoyable, if it wasn't for the current state of my manhood.

"Rule one!" Lea said cheerfully while jumping to her feet and approaching me. Unable to defend my manhood from her, I began trembling in anticipation of more torture. "We took all the pants from your bag. Buut... I bought this for you! Size S. Hope, it fits very tightly."

Holding a small, white speedo under my nose, she had put on a wide, excited smile. I was shocked, how much fun it was for her to humiliate me. Suddenly, she reached down and skillfully opened my belt and shorts. Squatting down, she then pulled down my shorts and underwear in one elegant motion.

My hard cock jumped out and nearly slapped her face. In retaliation, Lea sent a swift slap up into my balls. It wasn't hard, but the continuous busting of my balls made them more and more vulnerable. Ashley and Amber blurted out in girlish giggle, when my dick jumped out and I received a rough sack-tap for it. My cock and balls out in the open for the naughty girls was incredibly hot and frightening at the same time. Suddenly, Ashley reached down and grabbed my dick with her hand, right in front of Lea's face.

"It's not that small, Lea! Actually, this is quite nice." The blonde began jerking it and I instantly started moaning. All the ball-ache weirdly seemed to have increased my usual urges. Having the girl's tits pressed against my back and arms, previously seeing Liz naked and all this attention on my manhood had actually turned me on a lot more, that I would've believed - given the testicular pain and the insane feeling of vulnerability from me standing naked and restricted in front of my brat of a step-sister.

"Oooohhhh...." I moaned deeply, as Ashley cupped the tip of my cock with her palm and began working it at all sides with her fingers. Nearly instantly, I could feel the rewarding orgasm rise up. A rough ball-slap from my step-sis took me back down to the cruel reality, before I was actually pushed over the edge. She got back to her feet and her face was right in front of mine.

"Enough, Ashley! Rule two: you don't get to cum this week. If you do, I will kick your balls so hard that you won't, for the foreseeable time to come." I let out a desperate moan, as Ashley moved her hand down to my scrotum, gave the blue package a quick squeeze and withdrew her hand.

"Rule three: you will do everything we say at any time. And you will address us with 'mistress' or 'goddess'.
And finally: I will get the private room. But I will let you choose, who sleeps with you."

I looked up at her in disbelief of this kindness. Her impatient expression told me that I had to decide now. It was hard, but given the previous ten seconds, I had an answer for her right away.

"Ashley!" I growled, my voice still unsteady from the pain in my crotch. From the right side, I received a soft kiss from Ashley on my cheek, simultaneously with Amber's fist swinging into my bare balls from the left with a loud clap.

"Fine!" Lea said while grabbing my hair and holding me upright. "I'll leave you two alone. Have fun, Ashley!"

Before leaving, Amber yanked me around and rocketed her knee into my naked balls. She actually looked quite annoyed about me not choosing her. It was one of the harder kicks I had received, but it just topped a level of pain that was beyond my imagination, anyway.

Lea giggled again, as she let go of my hair and I sunk onto my knees in between the three girls in bikinis. Before she left, she pulled my shorts and underwear off my ankles and took them with her. I heard the door close and felt the intimacy of being alone with Ashley. Of the four girls, she had so far been the kindest and most playful one.

Suddenly I felt her hand sympathetically padding my back. I turned my head and looked right at her huge, bare tits, the blue bikini top falling onto the floor next to me. Nude, except from her tight bikini bottom, she leaned down, swung her arms around me and helped me to my feet.

"Lea is so mean to you!" Ashley said, but not without a hint of amusement, while turning me around by my shoulders. I instantly bent down, terribly aware of the constant danger when facing one of the girls at close distance. When Ashley realized that I was trying to get back onto my knees, she roughly pushed me backwards onto the bed.

"But with me, you can cum as many times as you want, honey!" Before I could close my legs, she was on all fours in between them, slowly approaching my raging boner with a sensual expression of desire. I twitched pathetically, when she grabbed me by the balls, softly but still immensely painful.

"Oughhh, careful please. My balls hurt so much..." I begged her to be gentle. Ashley laughed a mindbogglingly sexy laugh before looking into my eyes again.

"I know. But you gotta let me have some fun, too." With that, she swiftly took my rock hard cock into her mouth, not letting go of my nuts in her moderately strong grip. The rush of sensations instantly made me fall me flat onto my back, my arms stretched out on either side.

Ashley's blowjob was so fucking amazing that for the first time, I was truly happy about one of the girls having fun with my manhood. My mind raged in desperation, when after only a couple of seconds, I approached orgasm rapidly.

But the moment, my cock started pulsing, Ashley dug her fingers into my balls brutally, instantly taking me off the edge. The pain was absolutely emasculating, but I was so fucking thankful for every additional second, I got to enjoy her treatment. I moaned louder and louder, until suddenly the great sensation stopped and gave way to only testicular pain.

"Shhhh. Keep it down. If your sis hears you, you probably won't cum for a few days. Wouldn't that be such a shame?" With that, Ashley moved up a bit further in between my legs, placed both elbows on the mattress in front of my groin and grabbed one testicle with each hand while wildly sucking my cock.

"Ohhhh gosh..." I tried to keep it down, while an epic battle of pleasure and pain is taking place in my manhood. The things, this girl was able to make me feel... all of it blew my mind.

The pulsing began once again, but the expected squeeze didn't happen. Suddenly, I was over the edge and wonderful shivers ran though my system. Ashley continued working my cock and balls just perfectly to get the best out of it. Never had I cummed remotely like this.

When the colorful shiver of joy finally ebbed off, I opened my eyes and saw the amazing girl standing over me in between my still opened legs. She was so beautiful and hot. I soaked in her body to remember every detail. The remaining ache in my balls actually felt quite arousing in the aftermath of this amazing orgasm.

"Thank you..." I pressed out with an unsteady voice. A sudden snap kick into my unsuspecting balls took me out of my trance. Right after cumming, my scrotum was always very tight. Lying on my back with my legs spread, it held Ashley's target in a perfect package against my pelvis. I shrieked and tried to roll onto the side, but Ashley's foot pinned down my thigh.

"Thank you... who?" she smirked in an amused, suggestive tone.

"Thank you, goddess!" I moan in between my pathetic panting.The giggling girl jumped down the bed, put on her bikini top and left the room without another word.

"Fuck!" I panted, when she left the door wide open. Instantly, I jumped up and closed it. With only a shirt on, and my cock wet and with some ropes of cum around it, I really didn't want to meet Lea. Actually, I needed to get into the shower, quickly.

I put on that ridiculous speedo and involuntarily bent over from the pressure it put on my balls. It really was size S! Unbelievable, how my step-sis managed to bust my balls even without being present. Unfortunately, there was no alternative. The girls had removed every single piece of pants or underwear from me and my travel bag.

When I didn't hear any sounds outside, I sneaked out and right into the bathroom. Turning the key in the lock was a great relief. I hadn't been able to escape my sister's and her friends' mean games for hours. It was an even greater relief to get out of that super tight speedo that actually fully failed to hide the clear outline of my genitals, and to let my aching balls hang freely without the risk of a girl's fist or foot punishing them for their entertainment.

The steaming hot water cleared my mind a bit. I had no idea how I was supposed to get through one week, if it went on like this. But what could I do? "Hey mom, can you pick me up? My sis and her friends are constantly kicking me in the balls." didn't sound too reasonable.

My thoughts found a sudden halt, when I heard the sound of a closing door, very close. My heart raced. I had locked it, right? I was 100% sure. I stepped to the spot where the green shower curtains met and opened them with both hands to peek through.

The moment, I could look through the opening, I saw a fully nude Amber launching a kick up in between the curtains. Instinctively, I jumped up and back as far as the booth allowed, while looking down. The familiar foot with the painted nails split the curtains and met my groin just as I came down from my little jump.

It was really cruel to watch my own balls getting flattened by the girl's foot. My still slightly inflated cock bounced up against my belly while my poor balls took all the impact once again, trapped by my thighs and pelvis. When the pain that had become so familiar and yet so unbearable, hit me, I even saw black spots occupying my view. The mean bitches almost had me passed out from kicking my nuts!

I sunk down in front of the opening a moment before Amber stepped in, her pussy right at one level with my face. Her round hips, narrow waist and boobs nearly as large as Ashley's looked so perfect right in front of me. After halting a moment to look down at me, Amber stepped under the stream of hot water.

Fascinated, nearly hypnotized, I watched her graceful body as she moved her hands all over it. Despite cumming only a few minutes ago, I could feel the arousal building up. My cock, however, after just shooting out his load and dealing with countless kicks to the balls, needed another few minutes. When Amber looked down at where my hands still cupped my balls, she looked rather annoyed.

"Are you serious?" she hissed while turning to me, spreading her legs and placing her fists on her hips. "Is this not good enough to get you hard?"

"I just ca...", I blurted out, but stopped before making a terrible mistake. "... sorry, mistress."

"You better be! Now get to your feet, spread your legs and put your hands behind your head." Her dominant voice didn't allow any second thoughts. Having her perfect, flawless body openly exposed in front of me, I was very aware that I wouldn't be able to physically defend myself from the girls with this pair of vulnerable testicles that I couldn't even try to hide anymore. All I could do, was trying to gain their favor and begging that they would be as kind and rewarding as Ashley. Still in unbearable pain radiating from my balls, I struggled to my feet and followed her orders.

"Please have mercy, mistress."

Amber stepped forward and softly lifted my balls up with her open palm. My balls were so swollen that they looked massive in her hand. Suddenly, she pulled back her stretched arm and took a swing far behind her butt. When her hand started accelerating, I winced and pulled my hip back. Amber's eyes narrowed and told me that this was a mistake.

"Close your eyes!" she commanded and I instantly complied. The anticipation was brutal. Every cell in my body shivered, as I stood with my legs spread and fingers laced behind my head, fully unaware of when the girl was going to hit me in my openly presented manhood. "You will receive a sack-tap every ten seconds, until you got your dick hard enough for me."

The sound of skin slapping on skin was audible a moment, before the first sharp sting hit me. I moaned and bent over, but managed to stay on my feet. Thankfully, her hits were not very hard.

Of course, I never had trouble getting my cock hard, but with the pressure of being slapped in the balls until it worked, right after cumming to the best blowjob of my life, it was actually quite difficult. Around the fourth hit, I opened my eyes a little bit to peek at Amber's hot, nude body in the shower. She just went on cleaning and rubbing herself while casually leaning over and snapping her hand into my groin.

Around the eighth or ninth hit, I finally felt my cock accepting his little recovery time. Within the next two hits, it was fully up and craving the touches of the nude hottie. Again, the ache in my nuts that was not overly defeating in this case, actually helped to get me insanely horny again.

I opened my eyes and grinned at her with some pride. Fully hard, my cock really was massive. When Amber looked over to check if another slap is necessary, she put on a naughty smile.

"Why did this take so long, sweetie?" Without hesitation, she grabbed my balls, went down on her knees and pulled me towards her. I had to waddle forward rather awkwardly, given that my balls hurt like hell and I was pulled by them.

A second after the humiliating pull, her mouth took in my cock and I was in heaven again. As before, the wet blonde's hand stayed wrapped closely around my testicles, making sure that I couldn't go anywhere and that I wasn't cumming too early. Amber was at least as skilled with blowjobs, as Ashley was.

After being rejected to cum at least five times with a squeeze that made me cry out and my knees nearly give in, Amber finally allowed me to. The hot water running down my face and body somehow increased the sensation. Only minutes after that previous amazing orgasm, I was once again taught the wonderful and brutal power of women over men. I came so hard, I couldn't believe it, given the short recovery.

"Thank you, goddess." I remembered my rules this time, as Amber got to her feet. Instead of being floored with another kick or knee thrust, she simply gave me another swift sack-tap as she passed me to get out and dry up.

I stood in the shower another few minutes, one hand against the wall and one carefully cupping and nursing my balls. I totally had lost count of how many times I had received a kick, punch, knee, slap or simple sack-tap this day. In combination with the two amazing blowjobs in quick succession, my groin was an aching, throbbing mess. I really had no idea, how I was supposed to endure this for another six days!

When I got out, Amber had already left. I cursed silently, when I saw the speedo on the floor next to my shirt. The tight fabric stretching over my balls and making them clearly visible as two large bulges under my large cock, was extremely humiliating and painful.

So far, I hadn't been kicked in the balls while wearing this speedo. But I imagined it to be terrible. When I pressed against my balls from below, there was nowhere for them to escape. For a moment, I considered just leaving the bathroom naked. But this wasn't a great idea either, I figured.

I stepped out into the living room and saw the girls gathered around the couch in their bikinis that complemented each other so colorfully. Amber, Ashley and Liz sat on the couch and grinned at me, as I stepped out. Lea stood in front of them with her hands on her hips.

"Is there something you want to tell me, Paul?" she said in a strict voice. I glanced at Amber and Ashley carefully.

"Sorry, babe." they said in unison, in the sweetest voice of innocence.

"Fuck..." I silently cursed. I could feel the speedo tightening around my nuts in anticipation of what was about to come. Holding my beaten, tortured testicles in place for my sister's foot to kick them as a punishment for being seduced by her fucking hot friends.

I made a soothing gesture with my hands as I approached her. Her dangerously narrowed eyes left me unsure if she was actually angry or just excited to carry out her naughty plan to subjugate me all along. With my hands still in front of my body, Lea stepped forward surprisingly fast and launched up her long, sexy leg. I tried to protect my nuts from her kick that was executed without mercy, but I was too slow.

As expected, my balls were held in place by the ridiculously tight speedo and absorbed all the sisterly love from the top of her foot. I plunged into the carpet at her feet, face first. The last thing I heard before actually passing out, was the other girls' giggle. Only one of the girls sighted in an expression of shock and cute empathy. Ashley, I bet... Maybe she was going to nurse my balls later, if they made it through the day. What a vacation this was...
