Pool Boys - Part 3

Xander was still running his hands over his massive new frame, marveling at the sheer size of his muscles and trying to process the enormity of his pecs because he couldn’t see much past them. His fingers traced over the grooves in his abdomen, and he flexed his biceps, watching them bulge to impossible proportions, the sight still feeling unreal to him. Xander couldn’t stop smiling despite the confusion and terror the whole episode left in his mind. He was still processing the results of his transformation. But he felt a deep, primal satisfaction in his muscular and powerful frame.

But as Xander continued to admire his body, a faint sound broke through the silence. Footsteps. Someone was approaching, and before he could turn around, the pool began to glow intensely once more, the same red light as before, signaling that something else was about to happen. Xander turned around toward the house as fast as his massive weight allowed him, his enormous pecs bouncing from the sudden movement, and saw Paul stepping out of the house.

Paul was rubbing his eyes, having just woken up, but even in his groggy state, he looked stunning. His messy hair made him look cute. He was still shirtless, only his pajama pants covering his lower half. His perfectly sculpted, broad chest caught the sunlight, making the muscles look full even so early in the morning. His Captain America pajama pants hugged his hips, muscular thighs, and massive bubble butt so nicely that Xander couldn’t help but gasp. The pajama pants were a little too tight on him, something that Xander loved about Paul’s wardrobe, the fabric straining to contain Paul’s round butt and thick thighs.

“Xa–Xander?” Paul said, his voice groggy at first, but as his eyes adjusted to the sight before him, they widened in disbelief. His face turned pale, his mouth falling as he stared at the Hulk before his eyes, with Xander’s face on it. “What the hell happened to you?!”

Xander smiled, still overwhelmed by the situation but loving Paul’s reaction. “Paul, I—uh, I really don’t know, man. I don’t know how to explain this,” he said, his voice now sounding deeper as he looked down, only to see the expanse of his pec shelf before him.

Paul blinked repeatedly, still frozen, as he stared at Xander in shock. His eyes inspected the massive body in detail, up and down, unable to comprehend how much bigger Xander had become. “You’re—You’re huge! Freaking HUGE!” he finally exclaimed, stepping closer without even realizing it. His gaze fixated on Xander’s pecs, which jutted out so far that they blocked his view of the rest of Xander’s torso. The sheer size of them was mind-blowing, and Paul couldn’t help but feel awe and excitement bubbling up inside him.

“Yeah, I kind of noticed,” Xander chuckled, playfully flexing one of his massive arms and popping his pecs, making Paul gasp at the magnificent movement. “It’s a lot to take in.”

“Fuck yes! I can tell. Fucking awesome!” Paul exclaimed as he approached, still in a daze, and then he noticed the pool glowing behind Xander. “Why is the pool red? Does it have something to do with you getting this big?” How did this even happen? You grew like The Hulk?”

Xander shrugged, his massive deltoids flexing and relaxing as he tried to explain. “I don’t know, man. I was walking around, about to stretch, and then this weird lightning came out of the pool and hit me in the chest. My whole body started feeling tighter, and the next thing I knew, I was this big.” He gestured down at his colossal frame, his pecs slightly bouncing as he did. “It was like the pool shot some growth energy into me.”

Paul nodded, but he wasn’t really listening. His eyes locked on Xander’s body, his thoughts racing as he tried to process what was in front of him. Xander was no longer the athletic, muscular guy Paul had known. He was a mountain of muscle, each inch of his body impossibly thick and defined. Paul felt his breath hitch as he stepped even closer, his hands itching to touch Xander’s massive chest as he felt his dick softly stirring in his pajama pants. “How does it feel?” Paul asked, his voice low, almost as if he were in a trance. “How does it feel to be... this huge?”

Xander, noticing the look in Paul’s eyes, grinned. “It feels... awesome. I feel powerful. Like I could conquer the world,” he said, striking a double bicep pose to showcase his enormity to tease a clearly excited Paul.

Without thinking, Paul began to circle around Xander, his eyes roaming over every inch of his friend’s body. He slowly walked, taking in the sight of Xander’s massive shoulders and how his lats flared out, giving him a V-shaped torso that seemed unreal. “Fuck! You’re massive,” Paul whispered under his breath, not even realizing he had said it out loud. “This is insane.”

Xander chuckled, enjoying the attention. “Yeah, I don’t think my old clothes are going to fit anymore.”

“Man, you won’t fit through regular doors. No fucking way you’ll get into your old T-shirts. And where the-” Paul said aloud, still not really thinking his words before they escaped his mouth. “Where the hell are your pants?” he exclaimed but immediately noticed the shreds and rags of Xander’s pajama pants on the floor. Paul briefly stared at Xander’s crotch, now looking fuller than before.

“Well, they... they...” Xander tried to look down to find his ruined pants on the floor, but his pecs didn’t allow him to see much.

“You burst out of your pants?” Paul said, his voice high with surprise and excitement as he stepped in front of Xander again.

Paul’s eyes were wide open, and his dick was half-hard in his pants. With each passing second, his lust for his friend’s new body was taking more over him, blurring his thoughts. He had never felt drawn to Xander’s physique in that way because they were only best friends, but now he couldn’t help but feel lust and desire over him; the enormous body was too much to ignore.

Paul’s hand lifted almost instinctively, reaching toward Xander’s enormous chest. He hesitated for a second, but the temptation was too much. Slowly, he placed his hand on Xander’s pecs, his fingers trembling as they made contact with the dense, solid muscle. “Fuck,” Paul breathed, his hand moving gently over the massive slabs of muscle. “They’re so big... and so firm.”

Xander’s smile widened as he enjoyed Paul’s admiration and touch. “Yeah, they’re pretty hard to miss,” he said with a laugh, flexing his pecs slightly, causing them to swell under Paul’s hand. Paul’s fingers squeezed the muscle gently, marveling at the sheer size and strength beneath his touch.

“Fuck,” Paul whispered for the millionth time, his eyes wide as he continued to caress Xander’s chest. “This feels fantastic.”

As Paul continued his inspection, his hand slid down Xander’s chest and around to his back. He traced his fingers along the thick ridges of Xander’s traps, then down to his lats, feeling the massive expanse of muscle on his friend’s back. “You’re like a brick wall,” Paul murmured, his voice full of awe as he admired how Xander’s muscles shifted under his touch.

Paul took a few steps backward to get a better look, still entranced by Xander’s new body. His eyes roamed up and down, taking in the full extent of Xander’s transformation. He was so caught up in his admiration that he didn’t notice how close he was getting to the glowing pool. The water’s light began to pulse brighter, and Xander’s smile quickly faded as he realized the danger.

“Paul, get away from the pool!” Xander shouted, his voice full of panic. But it was too late.

Before Paul could react, a red jolt of electricity shot out from the pool, crackling through the air with a sharp, sizzling sound. The bolt struck Paul squarely on his butt, sending a shockwave of electricity coursing through his body. Paul’s eyes widened in shock, his mouth opening in a silent scream as the electricity hit him like a freight train. His entire body tensed up, his muscles locking in place as the high-voltage charge surged through him.

The pain was unlike anything Paul had ever felt before. It was as if every nerve in his body was set on fire, the electricity coursing through his muscles and bones. He collapsed to the ground, his knees hitting the cold tiles with a dull thud, his hands splayed out in front of him as he tried to steady himself.

Xander watched in horror as Paul writhed in pain, the red electricity crackling around him. “Paul!” he yelled, rushing forward but stopping a few feet from the pool, afraid of getting too close to the water’s strange energy. His massive chest heaved as he stood helplessly, unable to do anything but watch.

Paul’s body convulsed, his muscles twitching uncontrollably as the electricity continued to course through him. His pajama pants, already tight, clung to his body as his muscles spasmed with each pulse of the charge. The high-voltage current surged through his entire form, and for a few agonizing seconds, it seemed as though the electricity would tear him apart from the inside out. But then, just as suddenly as it had started, the pain stopped.

Paul’s body went limp, collapsing entirely on the floor with a gasp. Steam rose from his skin as the last remnants of electricity dissipated. He was breathing heavily, trying to catch his breath, but he was alive. Unharmed.

Xander rushed over to Paul’s side. “Paul! Are you okay?” he asked as he slowly knelt down beside his friend, his gaze flickering over Paul, expecting what was about to happen.

Paul didn’t answer right away. He was still catching his breath, his body trembling slightly from the aftereffects of the shock. Finally, after what felt like an eternity, Paul moved weakly. “I-I think so,” he whispered, struggling to push himself up onto his hands and knees, succeeding with Xander’s help. “What the hell was that?” he asked.

Paul’s chest heaved with each breath, his skin tingling from the residual energy as if tiny sparks were still dancing across his skin. He looked down at his trembling hands in disbelief, surprised he had survived such an intense shock. Every muscle in his body felt tight like they had been pushed to their limits and beyond. Xander knelt beside him, his strong hand resting on Paul’s shoulder, his brow furrowed in concern. But he couldn’t hide the look of knowing anticipation in his eyes.

“That’s what I was talking about... the pool, the red lightning,” Xander explained as Paul panted, still struggling to catch his breath.

“I can’t believe I’m still—” He stopped abruptly, his words caught in his throat as a strange, unfamiliar sensation washed over him. His muscles, which had felt tight before, suddenly tensed up even more. A low groan escaped his lips, his eyes widening in confusion as the sensation grew stronger. “X-Xander, something’s happening,” Paul muttered, his voice strained as his body began to feel warmer, as if heat radiated from deep within his muscles.

Xander’s expression shifted; his concern was evident, but he was also excited to see the result of Paul’s growth. “Paul, listen. Calm down,” he said firmly, his hand gripping Paul’s shoulder a bit tighter. “I think I know what’s happening. It’s the same thing that got me this big. Don’t freak out, okay? Breathe.”

But Paul could barely hear Xander’s words. The heat inside him grew more intense, spreading from his core to every muscle and every limb. It was like his whole body was on fire, but not in a painful way—more like a deep, overwhelming pressure that made his skin feel too tight. His muscles were pressing up against the limits of his own body. He groaned again, louder this time, as his muscles began to expand.

The first thing he noticed was his arms. His biceps, already firm and defined, swelled with new mass, the muscle fibers thickening and bulging beneath his skin. His triceps followed, expanding rapidly, the muscles growing so fast that his skin began to itch and stretch. Paul’s arms trembled as they grew, each movement making the muscles bulge even more, his veins popping out against the tight skin. 

“Xander… I—” Paul groaned, but his words got lost in a sharp inhale as his chest followed suit. His pecs, already broad, began to inflate like they were being pumped full of air. They swelled outward as his entire upper body widened, his lats flaring out and making him look more imposing. Paul’s breaths came in short gasps as the expansion continued.

“Just breathe, Paul. Don’t fight it. You’ll be alright, I promise,” Xander said, stunned by the spectacle before him. Paul’s body was rapidly expanding, muscle after muscle thickening and bulging with power.

Paul’s legs were next. His quads thickened dramatically, the muscles ballooning beneath the tight fabric of his pajama pants, which strained audibly against his rapidly growing thighs. Paul let out a groan as the muscles pushed outward, his quads becoming so thick that his legs were forced apart by their sheer size. The fabric of his pajama pants creaked, the seams struggling to contain his expanding legs.

And then came the most dramatic change of all—his ass. Paul’s round, muscular butt, already huge and firm to start with, began to grow at an alarming rate. The muscles swelled, thickening and rounding out even more until they were straining the back of his pajama pants to the limit. His ass grew and grew, the fabric stretching and struggling to handle the new mass, and Paul could feel the pressure building with every inch they expanded.

“N-no… what’s happening?” Paul gasped, his hands reaching back instinctively to feel his butt as it continued to inflate. His fingers dug into the growing muscle, but he couldn’t do anything to stop the expansion. His pajama pants, which had been clinging to his body like a second skin, finally gave way with a loud tear, the fabric ripping right across the back as his butt pushed through. Within a few seconds, Paul’s butt backside was fully exposed as the remaining shreds of his pants and underwear fell to the ground.

A relieved groan from Paul followed the tearing sound as his lower body continued to thicken. His ass was now enormous, each cheek round and firm, beyond the limits of logic with their sheer size. They jutted out behind him like a pair of beach balls, as big as Xander’s pecs, defying gravity with their incredible mass. Paul’s quads and hamstrings had grown to match, but it was his butt that stole the show, massive and impossibly large.

Xander stared wide-eyed, unable to tear his gaze away from the sight. “Paul... butt, man... It’s freaking huge,” Xander muttered in awe.

“I… I can feel it…” Paul panted, his body trembling as the transformation continued.

Paul’s shoulders broadened, his traps thickened, and his back muscles expanded, giving him an even more powerful, imposing figure. His arms were now massive, his biceps and triceps bulging with strength, and his chest was incredibly thick and broad, though not nearly as big as Xander’s. Every muscle on Paul’s body had grown to incredible proportions, but none compared with his ass, which was now beyond anything he could have imagined.

Paul groaned again, his muscles twitching as the last remnants of the expansion settled into place. He was a massive wall of muscle, about 600 pounds of pure, dense muscle mass now packed onto his body. He was as big as Xander, but his pecs weren’t nearly as big as Xander’s. And his ass—two massive, perfectly round globes of muscle that defied logic with their size, each one looking like a beach ball strapped to his lower back—was gigantic compared to Xander’s.

Paul tried to move, still trying to catch his breath, but his new weight made him clumsy. “Wow! Wow! I—” he exclaimed, his voice shaky as he struggled to get used to his new size.

Xander was still stunned by the sight of his friend’s transformation and quickly moved to help. “Hang on, I got you,” he said, placing his hand on Paul’s arm to steady him. With some effort, Xander helped Paul to his feet, though Paul wobbled unsteadily, his legs adjusting to the new bulk of his butt behind him.

As he stood, Paul turned slowly, his eyes wide as he inspected his own body. His hands moved over his chest, arms, and down to his quads, feeling his muscle’s new size and strength. He adjusted his stance until he was able to stand on his own. Xander moved away a few inches, letting Paul get used to his new body. His ass stuck out so far that he had to adjust his posture to keep from tipping over, his lower back arching slightly to accommodate the massive muscle.

“I can’t believe this,” Paul whispered, his voice filled with awe as he turned to look at Xander. “I’m… I’m huge. So powerful.”

“Told you. It feels fantastic,” Xander said, his smile broadening. “You look awesome. And this ass, fuck,” he said, slowly reaching for Paul’s bare butt to touch the most beautiful ass he had ever seen.

“Hey, hey, hands away!” Paul said, playfully punching Xander’s pecs.

“You touched my pecs; why is this different?” Xander responded, pushing his massive chest against Paul’s body, his hands still moving over Paul’s butt. “The cheeks are too big not to touch them.”

Paul glanced over his shoulder, his eyes widening as he took in the size of his backside. “Fuck,” he muttered, his voice filled with disbelief. “They’re… they’re gigantic!” Paul said as he ran one of his hands over his ass, marveling at its size and firmness. “How will I find pants big enough to cover this?” he said, half-joking.

Xander chuckled as he looked down at the remaining parts of Paul’s clothes, still covering a bit of his body. With one quick move, Xander pulled at the fabric and removed everything that was left, leaving Paul fully naked in the middle of the backyard and making him blush. “I don’t think you’ll need this anyway,” he said, throwing the fabric away.

“Hey! That was covering my crotch!” Paul said, instinctively moving his hands to cover his dick. Then he reached for Xander’s underwear and quickly ripped it off, leaving Xander also exposed. “I don’t think you’ll need yours either.”

Both of them laughed as they observed their naked bodies, admiring each other’s physiques. They were still confused. But they couldn’t hide their excitement about their gains. Their big dicks were hard, evidencing their arousal. Xander’s hand was resting on Paul’s butt, while Paul’s hand rested on Xander’s pec. They were entranced into each other’s bodies when they noticed the pool glowing brighter again.

“Uh, maybe we should stay away from the pool from now on,” Xander said, looking at the red glow intensifying again.

Paul nodded slowly, still trying to process everything that had just happened. “Yeah, good idea.”

While both guys stepped away from the pool, they heard footsteps behind them. The pool glowed even brighter as the footsteps approached. Deep inside they wanted to warn Justin about the pool and prevent him from getting struck by the red lightning, but as they exchanged knowing looks, they smiled, waiting for Justin.
