Aaron's eyes fluttered awake, his pupils dilating as they adjusted to the darkness that still pervaded. His sight unblurred as his vision focused on the clock on his nightstand: 4:00AM. God, he barely got any sleep. As his consciousness began to return, he realized why he had woken up.
A massive, heavy arm was draped on top of him. The athletic teen gulped as he realized how sweaty he was, almost uncomfortably so. The sheer amount of heat that was coming off the giant that was still slumbering beside him. He could see a bead of sweat percolate on Kyle's gigantic bicep, as it ran down the boulder-huge muscle, it gathered more sweat before falling off the cliff and landing on the much smaller brother.
Not only did he feel the sweat and heat, but he could feel Kyle's new massiveness up close. It had only been a matter of hours, yet he could already tell that his monstrous younger brother felt harder, more powerful, and most definitely BIGGER than he did before they went to bed. He tried to pull himself a little bit away from the beast beside him, only to feel the amount of cum that glued their bodies to each other. He could make out some that had slightly crusted over on his own abs, his brother's cinderblock-studded abgut had a layer of seed on it as well. Aaron wondered if it was old or new cum, and if it was his or Kyle's.
He got his answer when he felt his dick jolt. God, it was almost painfully sensitive. Judging from how even the slightest breeze sent prickles up his 9.5" rod, he guessed that he'd been the one to make the sizeable mess between them. He peered over, to see that his brother's massive meat-log was resting on his thigh, the leviathan of a cock was also hard. Aaron bit his lip as he was suddenly aware of the monster's length, it's girth, it's immense size. He could feel Kyle's heartbeat through the finger-thick vein running down its length!
The beastly, 800+ pound brother also began to stir and Aaron's heart skipped a beat. As Kyle began to wake, he idly reached down to play with his megalith of a dick, completely oblivious to his tiny brother! It wasn't until he heard the little guy moan that he realized he wasn't alone. A devilish smile broke out on his handsome, thickly bearded, square-jawed visage. He looked down to see that he had blown huge loads all throughout the night, coating half of his brother's room, as if to claim it for his own.
"Morning, little bro," Kyle snickered. He didn't even ask Aaron before lifting him up by the hips and spearing his older brother on his rod, letting out a satisfied huff as he began roughly plowing into the high school senior's ass. Kyle down, his beard brushing up against his heavy pecs. He could see the outline of his giant cock distending his brother's innards. It definitely felt tighter than last night, despite Aaron never having enough time for his body to ever fully recover. The sight of it alone was arousing enough to send him over the edge and Aaron's tight washboard six-pack quickly bloated into a fluid-filled gut.
Kyle laughed as he watched Aaron whine, the smaller guy rubbing at his distended stomach. The huge musclefreak decided to show mercy and pulled out. Aaron huffed as the pressure was relieved, a river of Kyle's seed gushing out of his used hole.
The huge beast easily lifted Aaron’s body up towards his face and shoved Aaron’s comparatively tiny dick into his mouth. The smaller brother wailed as he felt the intense suction, how Kyle’s pleased humming rattled his body, how his younger brother’s beard chaffed against his inner thighs. It only took moments before Aaron was blowing another load down Kyle’s hungry mouth.
“Fuck, you taste good for a tiny guy, little bro,” Kyle chuckled. The huge, hung and still-ragingly horny beast looked at the clock and smiled. “Guess we got extra time to do an early morning workout!” he boomed, scooping Aaron up and tucked him under his arms. The giant waddled all the way down the stairs to the basement, his titanic length leading the way, a wake of pre-seed that dribbled out of Kyle’s immense rod tracing their path.
For hours, Aaron slaved away, only realizing that Kyle’s intensity in his workouts was even more intense than ever before. Kyle’s moans were more insistent as Aaron licked over his hairy muscles this morning. Kyle’s lifts were punctuated with heavy thuds as he had to continuously up the weights between sets.
“Hop on,” Kyle commanded as he got ready on the bench, an absurd amount of weight piled onto the bar. “Now, runt!”
Aaron scrambled, sitting himself down on Kyle’s heavy torso.
“Not there, little bro,” Kyle snickered. The muscle monster’s huge dick spasmed and pushed at Aaron’s back, sending the smaller brother reeling forward. A massive hand reached down and pulled the older brother up, his legs touching the lower edge of his bigger brother’s heavy pecs. With a grunt, he tore Aaron’s underwear off.
“Put it in,” Kyle grunted. To emphasize what he meant, he bounced his pecs in tandem, accentuating the deep canyon between his chest meat. Aaron shuddered as he inserted his pathetic erection. To a normal person, Aaron’s length would’ve been something else: 9.5” and incredibly thick. But, Kyle wasn’t normal by any standard of the definition.
Both brothers moaned as they felt the searing heat of each others skin on their own. Kyle felt the red-hot poker, Aaron’s shaft leaking pre-seed deep into the groove of his pecs. Aaron felt the incredible amount of body heat that Kyle produce amplified by the sweat that pooled in the crevice of Kyle’s chest. And then, Kyle started lifting.
Aaron bit his lip, leaning back as to avoid Kyle slamming the bar into his chin. His whole world shook when the bar hit Kyle’s chest. His nails dug into Kyle’s steely flesh as the huge man squeezed his chest at the top of the lift, encasing Aaron’s shaft in muscle on all sides. Aaron didn’t make it through half the set before he busted a nut all over Kyle’s neck, beard and moustache. Kyle rumbled, pausing mid-rep to lap up what he could of Aaron’s seed before continuing.
The ‘torture’ continued; Kyle putting Aaron’s shaft in the crook of his arm as he did concentration curls, lathering up Aaron’s cum onto his gigantic biceps before licking it off in self-worship. He made Aaron lick his soccer ball sized balls as he used the leg adductor, crushing his brother’s head between his iron-wrought inner thighs with each rep.
By the time he was done, it had been 4 hours and the boys needed to get ready for school. Kyle took Aaron’s exhausted body and shoved his cock up Aaron’s backend, the little guy barely giving any resistance. He used his brother like a cocksleeve as he climbed the stairs. As they got to the main floor, they caught sight of their mother just about to head out for work. Aaron was mortified, their mom could clearly see that Kyle was in the middle of brutally air-fucking him! And yet, she gave them a stern look, and motioned at the wristwatch she had on, as if to say, ‘don’t be late,’ before she closed the front door behind her.
“Make me my post-workout shake, bitch,” Kyle grunted as he lined Aaron up with the kitchen counter and fucked him silly. Humiliated, Aaron mixed up a shake in a huge gallon shaker while his arms were wildly flailing from Kyle’s unabated, lust-filled thrusts. When he was about done, Kyle lifted him up and off his shaft and held him above the jug with one hand. The other reached down and stroked at Aaron’s length. The older brother let out another pitiful whine as he shuddered and blasted a big load down into the shake.
“Better get ready for school, bro,” Kyle chuckled, letting the smaller guy down and taking the shake into his hand. As he chugged the thick, almost paste-like concoction, he slapped Aaron’s ass, his dick bobbing as he watched that cute, tight ass walk away, his seed dribbling onto the floor.

Aaron could hardly concentrate at school. Now that his bigger dick was back, he could feel the familiar urges return, his teenage hormones running rampant. Only, now they seemed somehow amplified. He caught himself ogling girls, and quite a few of the guys in English class. Fuck, what would it feel like the put his 9.5” cock in between a girl’s breasts and repeat what Kyle had made him do? He bit his lip as he imagined inserting his log into the school’s varsity quarterback’s tight, jock ass.
The teen slipped his big shaft up and out of his pants and into his baggy hoodie. He considered himself lucky that he had it as he began to idly stroke at himself underneath the fabric. The other reason he brought it was to hide the cum-baby he was nursing, Kyle had really stuffed him this morning!
When lunchtime came around, Aaron rushed to the accessibility washroom and locked the door behind him. He whipped out his dick and furiously beat off into the toilet, spraying a giant load after just a few seconds. Holy hell, how was he so productive? Kyle had milked him for hours this morning and he was still blasting out loads this big? The teen didn’t question it further as he wiped up and flushed the toilet, finally feeling a little relief. He was going to need to find an outlet for all this pent-up energy.
He passed the weight room and got an idea. Maybe he’d be able to get the blood out of his groin and into his body, at least for a while. He got dressed into his gym clothes, pausing to glance at his reflection in the mirror. Apart from the slightly rounded gut he was sporting thanks to Kyle, he looked like your typical high school jock; decently tall and muscular. It was a far cry from the short, mousy guy he had used to be before the spell Madame Illusia had cast on him and Kyle.
Aaron noted the other guys using the equipment in the gym, most guys looked like him, some were more muscular, some were tanks of fat and muscle. He was glad the bump in his stomach didn’t stand out too much.
“Yo, Aaron,” a deep voice called to him. He spun around to look at the quarterback he’d been fantasizing about all morning. He was thickly muscled, but not overly so, limber enough to evade the real meatheads that were gunning for him on the field. “Dude, have you been working out?”
“Uh, yeah, man,” Aaron coughed as the jock sized him up and even gave his bicep a squeeze! The other dudes came up to him and congratulated him on his ‘gains.’ From there on in, he worked in with the other lifters, the guys taking him in as one of their own. Heck, even after lunch, the jocks that used to ignore him waved at him in between classes in the halls.
---
Aaron’s temporary elation was not to last though. After school, it was the same brutal treatment as ever. Only, he was more horny... and Kyle was definitely even hornier! It was like whatever new energy Aaron had, every time he came onto his younger brother, the effect was amplified! The huge man must’ve set a record that night with how many times he had cum inside his big bro.
Aaron didn’t have to swear that Kyle looked bigger after his workout, he definitely was. His arms looked like they must’ve added an inch to them, at least! The shaft that invaded his ass definitely stretched him out more at the end of the workout than it did at the beginning. And Kyle’s head was ever so slightly closer to the ceiling of the basement.
The routine continued. Kyle would fuck his brother senseless throughout the night, they’d fall asleep, and wake up early for a morning workout. Filled with extra testosterone from Kyle’s ever-increasingly brutal fucks, Aaron would barely contain himself in the morning before busting a huge load all over the toilets at lunch. He’d lift with his new buddies in the weight room before he’d have to serve his massive, growing brother throughout the afternoon. Wash, rinse, repeat.
By Wednesday, he noticed the different looks he’d get in the halls as he walked by in school. The guys in the weight room were now circling around him when did his lifts, huge cheers exploded whenever he finished a set. The guys showed him where the football coach had a huge stash of pre-made shakes for the guys in his always open office. Where the guys took one, they gave him three. His brother was getting even rougher than usual when they fucked in the afternoon throughout the evenings. Only, Aaron could feel himself pushing back, increasing the power of Kyle’s thrusts, making his bigger brother be the one letting out needy moans as they fucked.
By Thursday, he realized that those looks he was getting were ones filled with desire. Everyone could tell he was in the bathroom at lunch, pretending they couldn’t hear the beast grunt as he double-fisted his mighty meat. His shirt started to fray in middle of his workout and a huge wrestler tossed him his own 3XL t-shirt, the growing teen completely oblivious as to why even the new shirt felt really tight! As Kyle fucked him that night, the bigger teen’s hands couldn’t stop roaming across the strong, hairy expanse of Aaron’s body. The sex was rough and both brothers were getting into it. Kyle tweaked his older brother’s nipples and watched as Aaron shot a giant load that splattered against the ceiling of his room. For once, Kyle actually fell asleep before Aaron did.
By Friday, Aaron couldn’t deny that whatever magic had done it’s work in Kyle was now also affecting him! Before, he could deny it to himself, after all, whatever gains he had made, Kyle was growing even faster. But, after his workout with the guys at lunch, the quarterback cornered him in the locker room. The stud looked Aaron up and down as the now bigger guy pulled his tight t-shirt on, the hem only covering half of the lowest set of abs on him.
“Hey, you coming to the game tonight?” the jock asked, putting his hand against the locker. The scene was almost comical, the giant looking down sheepishly as the jock pinned him to the locker. A blush ran through Aaron’s cheeks. “C’mon, come watch us win. And after, we can hang out with the guys. Or...” The jock brought his other hand up and flicked Aaron’s huge nipple that jutted out of his shirt, causing the big guy to grunt lowly, and his huge bulge surge. “Maybe hang out without the guys?”
“I...” Aaron huffed, his voice deep and low. He bit his lip; Kyle would be angry. Furious even... But this was his chance to live out his own fantasies... He looked down, over the swell of his titanic chest and nodded.
“Awesome, see you then, big guy,” the jock chuckled, squeezing Aaron’s huge bulge before heading out.
Aaron knew he couldn’t go home after school, he’d get roped into worshipping Kyle all night, and forced to be his younger brother’s slave. So, the big teen hid out in the weight room after school, lifting heavy to draw his focus his attention away from how angry Kyle was going to be with him. The teen lost track of time. He waddled through the weight room, guzzling a huge shake while he stroked himself, thinking of the cute quarterback and what they were going to do tonight. It wasn’t until he realized that there wasn’t much light coming in from the windows anymore that it hit him how late it was. He looked up at the clock, eyes wide as he realized the game was going to start soon!
“Oh shit,” he boomed. He quickly finished his shake and made his way down to the locker rooms. As he thundered in, he looked down at the stunned gazes that all fixated on him. He had just barged in on the football team getting dressed. They all looked up at the 6’5” giant in their midst. They looked at how his 13” member jutted out of his crotch, distending the poor pair of black basketball shorts he had on, the basket gooey with his pre-seed. The final touch was when his stringer shirt failed spectacularly and his pumped off-season bodybuilder mass was on full display; 400 pounds of beef ready for everyone to ogle.
Aaron’s hands shot down in an attempt of decency. There were whoops and jeers. ‘Yeah, big A!’ ‘Donkey dick!’ ‘Damn, bruiser!’ All of which made Aaron’s cheeks burn. The cute quarterback was definitely checking him out, especially that humongous shaft that his shorts couldn’t hide. The jock tossed him a towel and nodded for him to hit the showers with a wink.
Aaron quickly shuffled into the showers, the only thing following him the friendly taunts from his new friends. He tossed his tattered clothes to the other end of the open showers and turned the water on, the stream hitting him halfway down his chest thanks to his increased height. He soaped himself up, his cock thankfully going down after all that embarrassment.
He could hear the guys doing their pre-game rituals, the team captain psyching up the boys. “... Let’s make a legend, boys, one bigger than Aaron’s over there!” he heard from out there. Laughs abounded as Aaron could hear the team march out.
As he shut off the water off, he turned around and had to hide his still half-chubbed dick as the coach popped his head in. The man coughed as he tried to pretend he couldn’t see the huge sausage dangling between Aaron’s legs. He tugged at his cap and looked to the side as he remarked, “Aaron, your dad’s here looking for you.”
Dad? Why would Dad be looking for him? He didn’t realize he was walking right into a trap as he came out of the showers. Standing in the locker room, nearly taking up the entire room by himself, was Kyle. The giant had his hairy arms crossed, a stern look on his heavily bearded face. It was no wonder the coach mistook his younger brother as his father!
“Thanks for helping me find my boy,” Kyle said gruffly.
“Uh ahem... no problem, sir,” the man replied, flustered from the encounter with such a huge man. “I can see where Aaron here gets his size, definitely has your genes.”
“Ha, this slacker?” Kyle snorted. “I was at least twice his size by his age.” Aaron just blushed at the remark, the coach didn’t know the half of that statement.
“Oh uh... ahem, well, I’ll leave you to it then,” the coach whimpered as he scuttled off to be with the team, leaving only Aaron and Kyle left in the locker room.
“Don’t even call or text, ‘son?’” Kyle chuckled darkly.
“K-Kyle, I can explain,” Aaron whined, his dick growing hard involuntarily, his body preempting the fucking it was about to receive as he watched Kyle’s massive dick rip right through his pants, the rod easily over 2’ of meat now.
“Yeah, you can do that while I breed you, kiddo,” Kyle growled as he pushed his way into the showers with Aaron, his shoulders taking a huge chunk of the tiled wall with him as he casually brushed past it. When the team would come back later that night, they’d all gawk at the incredible mess that was left behind; destroyed tiles, busted showerheads that had huge hand prints crushed into them, and cum... oh so much cum, piled over an inch thick all along the shower floors.
