Little brother is a muscular stud (Patreon)

Alex was posing in front of the mirror in his room, admiring his body and flexing his muscles, just as he did each morning after waking up. He was wearing only a tight pair of black boxers. At only 13 years old, he had the body of a small Adonis. His shoulders were broad and imposing and his core was slim, with visible abs any man wound kill to have. He always did 100 crunches before going bed to give his 6-pack a little boost, knowing he would grow more in his sleep. His arms were big and meaty, sporting large biceps and incredible looking triceps that belonged on a grown man who went to the gym regularly, certainly not on a boy who only recently turned into a teenager. His chest was wide and thick, just like his adult-shaming backside that was brimming with small crevices and huge slabs of teenage muscle. He was easily the largest boy in his class in every aspect. Hell, he was wider than any of the teachers. His legs were big and strong too, mostly as a result of him playing lots of sports in his free time. He loved wrestling and football the most. Standing 5 feet tall and 150 lbs, you could say than young Alex was quite the school stud. Nobody knew how he managed to grow such big muscles at such a young age, but all the girls admired his incredible physique. His parents were convinced that his genetics would be insane ever since he turned 10, but never took the time to take him to a doctor to see if anything might be wrong with him. They simply thought that he was experiencing his natural growing spurts, although in a more extreme way than the other kids.

The reason Alex liked flexing in his black boxers was to not get distracted by his throbbing cock during his flexing ritual. As it usually happens with boys his age, 9 out of 10 mornings he would wake up with a morning wood that wouldn’t go down until he jerked off properly. Covering his cock helped him concentrate on his gains, at least for a couple of minutes until the arousal became unbearable. As soon as he’s done flexing, he would pull down his underwear and finally let his raging erection free. 10.5 inches of hard meat rested between his muscular legs, accompanied by a pair of young hairless balls that were almost as big as tennis balls. Alex had a package that would put most grown men to shame and he still had a long way to go until he stopped growing. “Damn I’m hot!!” he thought as he hit a double biceps pose, making the peaks of his biceps rise and pulse with power. He tried to go for a most muscular pose next, but as soon as he got into the final phase and his muscles expanded, his underwear exploded and his cock burst out like a stripper out of a cake. “Damn! Another pair of undies goes bust. Gotta tell mom to buy me a couple new ones!” he said as he looked at his ruined boxers. He then got out of his room and went to the bathroom. The first thing he did was taking a good look at his gorgeous face. “Can’t compete with this face!” he smirked like a little devil. He brushed his teeth and then got into the shower. Just like every other day, his cock was still rock hard and not showing any sign of going down soon. That thing needed to be taken care of. Feeling the hot water running down his muscular teenage body, Alex started jerking off. “Oh yeah!! That’s it, bitch! Take my cock!!” he groaned and moaned as he stroked his big veiny dick, thinking of a certain girl he met after football practice the other day. A few minutes later, he came hard, blasting the wall of the shower with his creamy jizz. He fired five massive loads, more than a normal man could cum in an entire week. Even after that, his cock was still just as hard as before. “Well, I guess I’ll have to do one more! It’s a good thing I don’t have school today, otherwise I’ll surely be late.” Alex said to himself before grabbing his cock, feeling its incredible hardness unaltered by the previous orgasm. He then started stroking it again.

A couple more minutes later, someone knocked on the door. “Alex, are you in there?” said a sweet womanly voice. It was Alex’s sister, Nora. She was six years older than Alex. Standing 5’5’’ and around 110 lbs, Nora was very curvy girl. She had big natural boobs and a beautiful bubble butt, as well as a pair of crystal blue eyes and long eyelashes. Her natural hair was a shade of brown, but she recently dyed it red. What Alex always found fascinating about his sister was the incredible shape of her body. She had the shape of a pear, with wide hips and thick thighs. For someone who rarely exercised, Nora’s body was relatively fat free, except for some areas where it was mandatory for some fat to be present. Alex recalled seeing her in her trademark pink bra and black panties, rushing to the fridge to pick up a can of soda before going back to her game. She was a bit of a nerd, actually. Nora spent most of her free time playing videogames or reading comics, but she also loved teasing her baby brother, especially since he started turning into a muscular stud. She did that quite often, taking a seat on his back while he did pushups or asking him to perform squats while carrying her on his shoulders. She also loved opening the fridge as soon as he walked into the kitchen and bending over to pick something from a lower shelf just to see his reaction. Naturally, his cock would come to life and he would have a hard time covering it while Nora giggled like a little pervert. Alex caught her masturbating a couple of times too. Her moans were so erotic he would instantly get hard and require a swift session of jerking off. He loved his sister very much and she loved him too. “I really gotta pee, ok? Don’t mind me!” she said as she opened the door and entered the bathroom. Alex wasn’t ready for that. Seeing her blurry shape through the shower window, he couldn’t control himself anymore. He came hard, firing 7 loads of cum just as large as the ones before. Nora took a seat on the toilet the exact moment her brother blew his massive load. Startled by the sound of the cummy projectile colliding with the shower window, Nora asked her brother if he was ok. “Ahh sure! Don’t mind me! All fine here!” Alex struggled to say. But Nora wasn’t buying it. The massive splash of white goo was more than visible from where she stood. She finished peeing and immediately rushed towards the shower. “Alex, are you jerking off in the shower? Hey, I’m your big sister, you can tell me anything.” she said with a sweet and calm voice. But Alex was red hot with embarrassment on the other side of the glass. He stood there in complete silence, looking at the beautiful shape of his sister in front of the dirty glass. Seeing her majestic curves, even in blurred out form, prevented his cock from softening even one bit. He simply couldn’t help looking at that hot body.

“I’m opening it up, ok? Don’t freak out!” she said as she opened the door to the shower. As soon as she did so, she was greeted with an image she never expected to see. Sure, her brother was very buff for his age, but to also be so hung was really something else. She could see his throbbing erection in all its meaty glory. Alex’s cock was leaking pre on full display while the boy simply gave up trying to cover it with his hands. There was no point in trying to hide it as it was just too big and too hard. Nora didn’t know what to say. But her body more than reacted to what she was seeing. Her nipples hardened and her pussy started getting wet. “Wow… Alex… I didn’t know you were so… big!” she said softly after 15 seconds of staring at the pillar of meat shaking between her brother’s legs. “Sis… I… I’m sorry! I just couldn’t help myself and…” the visibly embarrassed stud tried to say. “Little bro, can you step out of the shower, please?” Nora said, her eyes still fixated on the huge member. Alex complied. Nora made way for him to step out, taking the time to stare at his muscular butt as he did so. “Fuck! Such a round and hard butt too. I’m starting to get jealous!” she thought. Alex turned around to face his sister, trying to explain the situation to her. “Nora, listen…” he started speaking, but was abruptly interrupted by what he saw next. Nora’s bra was resting on the floor and her tits were shamelessly pointing at Alex. He’s never seen Nora’s nipples so hard. They looked so delicious, so inviting. He wanted to squeeze them, then lick them and then fuck them with his oversized manhood. “Like what you see, little brother? Well, aren’t you the little pervert? Or should I say a BIG pervert?” Nora said as she took a few steps towards him. She stuck one finger in her mouth, making sure to get it nice and wet for what came next. “Sis…” Alex again tried to explain himself, but Nora wasn’t interested in hearing him out. She was interested in fucking him though. The big sister ran the wet finger all over Alex’s hard shaft, going from its fat nutsack up to his huge cockhead. “You want to fuck your sister, Alex? You want to stick this… BIG… FAT… COCK inside me? Or do you want me to suck it first? Get it nice and wet for you to pound my wet pussy? Do you know how wet you’ve made my pussy? Wanna see?” Nora said with extreme lewdness in her voice, emphasizing every word that referred to her brother’s shlong. She then spread her pussy lips apart with 2 fingers, allowing Alex to get a good look at the cunt he wanted to fuck ever since he discovered his cock was made for more than pissing.

“Have you been with other girls, little bro?” Nora asked as she massaged her wet pussy. “Yeah… about 20 or so.” Alex answered. Normally he would be proud of such a feat, but he wasn’t sure how his sister would react. Would she get mad? He didn’t know. But he didn’t want to lie to her. “Mmmmm you’ve been a busy boy. Tell me, do you want to fuck me?” she said with supreme confidence. Alex wasn’t used to being mentally dominated by a woman. Every other girl he fucked was more or less a slave to his huge cock. But Nora was different. She was family. In fact, she was more than family to him. “Yes…” he responded. “Yes what?” Nora continued, twisting her tongue in a slutty way. “Yes! I want to fuck you, sis!” Alex said with very little authority. “Then come here and lick my pussy, little bro.” she said as she massaged her clit, getting herself ready for her brother’s huge dong. Alex got on his knees and buried his face between his sister’s thighs. He started licking her pussy while she ran her hands through his hair. “Oh fuck yeah!! Go on!! Your tongue is amazing, Alex!” Nora moaned as she felt her brother’s tongue deep inside her womanhood. He grabbed her butt and squeezed it hard as he continued to eat her out like a good boy, using his tongue and meaty lips to get his big sister her off. A few minutes later, Nora was on the verge of cumming. “Oh fuck fuck!! Stop!! Alex, stop!!” she said, moments away from cumming all over his face. “You almost made me cum, little bro! But I don’t wanna do it until I taste that big juicy cock of yours. Get on your back!” she said, barely able to hold off the powerful orgasm. Alex got on his back and spread his legs, allowing his sister to get into position for a blowjob. She got down on her knees and immediately grabbed his cock with both hands. “Oh fuck!! I still can’t believe how big and hard this thing is. You’re a real boy wonder, you know that! Not even 14 and hung like a horse.” Nora said as she started jerking him off with both hands. She then put her lips on his cockhead and stuck her tongue down his pisshole while she continued to stroke. “Oh fuck… sis… your tongue… aahhh!” Alex moaned as his sister continued to work on his cockhead. She twisted and turned her tongue inside his slit while also using her lips to stimulate the exterior. Her stokes were very powerful, just like her tongue movements. Nora finally got a good look at her brother from below. His muscles were even more impressive up close. She wanted to lick his abs, to squeeze his huge arms and squirt all over his massive pecs. But first, she wanted to play with his cock a little more. She got her tongue out of his pisshole and started sucking him the old-fashioned way. Moving her head like a pro, she took more and more of his meat each time. It wasn’t long until she deepthroated the whole monster cock. She waited for a while, wanting to feel every fat vein on his rod as it stretched out her slutty throat. Alex’s cock was now covered from top to bottom in ludicrous amounts of Nora’s saliva. She wanted it very well lubricated before it went inside her tight cunt, knowing that this was the only way it would fit. She continued to suck the monster until it eventually started shaking violently. It felt like she had a raging volcano on the verge of eruption inside her mouth and throat. “Sis… I’m gonna… CUUUUM!” Alex moaned before his whole body started shaking and his cock exploded inside Nora’s mouth. He unloaded ludicrous amounts of jizz inside his sister’s pretty mouth while she made sure every little bit went straight to her tummy.

“Wow, you really a certified stud, aren’t you?” Nora said playfully, licking the last bit of sticky cum from her lips. “So, did you like it?” she said as she winked at Alex. “Fuck yeah!! You’re the best, sis. I never knew you were so good at this.” Alex replied with childish ignorance. “Well, I’ve been to high school so… Anyway, are you ready put that thing inside me?” she asked as she pointed at her brother’s still firm erection. “Bring it on!” he replied with visible confidence. Nora bit her lower lip with anticipation. She then assumed the doggy position and spread her asscheeks wide for her brother. “Fuck me you muscular stud!! Fuck your sister with that big fat cuntbreaker!! Make you sister a bitch to your muscular body and your massive manly rod!!” Nora taunted him as she smacked her asscheeks. Alex grabbed her by the hips and instantly inserted his cock into her soaking cunt. “OH FUCK FUCK!! SO… BIG!!” Nora moaned as she felt her brother’s cock stretching her pussy out. Alex then started moving his hips. He went slowly at first, allowing his sister to accommodate to his girthy cock. Each trust went deeper than the one before it, making Nora take more of her brother’s cockmeat each time he entered her. “Your pussy is the best, sis!” Alex moaned as he pushed more than half his dick into his sister’s tight cunt. “FUCK ME!! FUCK ME, ALEX!! FUCK YOUR SISTER LIKE YOU’VE ALWAYS WANTED TO!!” the girl screamed, enjoying orgasm after orgasm as a result of being split apart by the muscular stud’s dick. Alex complied and started moving his hips faster. He also made his thrusts deeper and more brutal. Less than a minute later, Nora was getting pounded from behind by the entirety of her brother’s monster cock. Her big boobs bounced wildly as her womb struggled to make room for the muscular stud’s man-shaming dong. She could feel his small yet very strong hands squeezing her wide hips and even smacking her ass from time to time. Little by little, she was becoming a little whore to her baby brother’s dick. But Nora couldn’t help it. It simply felt too good to be fucked by such a wonderful teenage cock. She could feel her brother’s hard body colliding with her butt and thighs each time he got balls deep inside her hungry cunt. It turned her on very much knowing that it was her 13-year old brother fucking her brains out. “I’M GONNA CUM AGAIN!! DON’T STOP!! FUCK ME MORE!!” she screamed as she came again and again, splashing her dear brother with her cunt juices. Alex had no intention to stop fucking her until he had no more cum left. He grabbed her arms and spread his legs more for an even deeper penetration. He fucked her like this for 30 minutes straight. Nora came more times during this half hour than her she did in her entire lifetime.

“I’M GONNA CUM INSIDE YOU, SIS!! GET READY!!” Alex grunted as he let go of her hands and buried his cock balls deep into her battered cunt. “YES!! YESSS!! DUMP ALL THAT HOT YOUNG CREAM INTO MY SLUTTY PUSSY!! I WANT IT, ALEX!! PLEASE GIVE ME YOUR POTENT TEENAGE CUM!!” Nora managed to say before she felt a powerful blast that shook her entire being. Alex dumped a ludicrous amount of cum into his sister’s guts. Her belly bulged and some of the creamy cum started leaking out of her from the sheer intensity of Alex’s cumshots. The teenage stud came like a firehose, giving his slutty sister every single drop of cum he had left in those huge balls. As soon as he pulled his cock out of Nora, a small river of jizz burst out. He managed to break his own record when it came to cum production in a single day. And it was all thanks to his lovely sister. “Look at that! You gave me a cumbelly, little bro!” Nora said as she checked out her bloated tummy. She looked like she was 6 months pregnant, but all of that was her brother’s potent seed. “I better make sure to get it out and grab a birth pill. Can’t be too careful with such a stud of a brother!” she said as she winked at Alex. It was only after filling up his sister with cum that Alex’s cock finally went down. Even flaccid, his dong was still massive by any stretch of the imagination. “I’m gonna take a shower now, ok?” Nora said as she kissed her brother on the cheek. “You better take a mop and clean up this mess before mom finds it. If you do it before I finish up, I’ll give you a nice little surprise!” she said with a girly giggle. “All right!” Alex said with a wide grin. Nora got into the shower and started to slowly push the cum out of her belly. It was incredibly thick and it proved quite a challenge to remove it from her still gaping womanhood. “No biggie! Alex will surely give me more!” she thought to herself as she watched her brother’s cum going down the drain alongside the water. She finished cleaning herself up, thinking of how much sex she was gonna have with her muscular stud of a brother from now on.
