Blake could do nothing as he watched his little brother grow bigger and bigger. He was too tired from the wrestling and simply fell on his ass.

The warmth in Cooper’s body intensified, radiating outward from his core. It felt like a gentle caress at first, soothing and pleasant, but soon, it grew into a pulsing heat that spread through his limbs like wildfire. His shoulders creaked audibly as they broadened, the bones and muscles swelling in size. He could feel each fiber stretching and knitting together, denser and stronger, as if unseen hands were reshaping him from within.

His narrow chest surged forward, pecs forming in powerful waves as his skin tightened over the growing mass. The sensation was electric, a mix of tingling and pressure, like a deep tissue massage that reached his very core. Each breath pushed his rib cage out further, the expansion so intense that it left him momentarily breathless. The soft cotton of his shirt stretched until it tore open, exposing smooth, rippling muscle underneath that seemed to radiate power.

Cooper’s arms were next. A tingling warmth spiraled down to his fingertips, followed by an almost euphoric pressure as his biceps swelled rapidly. It was as if someone had injected pure strength into his veins, his muscles inflating like balloons being filled with molten iron. Veins snaked along their surface, throbbing rhythmically with each beat of his heart. His forearms thickened, the sinews standing out in sharp relief as his fingers flexed involuntarily. He could feel the raw power coursing through his hands, the very act of clenching his fists sending a satisfying ripple through the newly formed muscle.

He gasped as his abdomen tightened and hardened, the sensation akin to a cold splash of water followed by a deep, internal pull. His stomach muscles reshaped themselves, one after another, until a perfectly carved six-pack emerged. The surface felt like polished stone, his obliques etching themselves in sharp, symmetrical lines along his sides, completing the transformation of his core into an impenetrable wall of strength.

Below his waist, his thighs began to tremble, then bulge outward as the same intense heat flowed through them. Muscles grew thicker with each passing second, the skin stretching taut over quads that seemed to burst with energy. His jeans strained against the expansion, seams popping audibly as his legs became tree-trunk-like pillars of raw might. His hamstrings rounded out behind him, their powerful curve emphasizing the sheer mass of his lower body. His calves swelled into perfect diamonds, their dense shapes rippling with every subtle shift of movement. Cooper’s shoes groaned as his feet widened and grew, the ground beneath him feeling smaller, almost fragile under his enhanced weight. He stood taller, his entire frame having gained inches in height, his body a monument of strength and power.

Julian stared at Cooper in shock after he got off the couch, but before he could speak, the same overwhelming heat surged through his own body. It hit him like a tidal wave, warm and exhilarating, spreading from his chest outward. His already athletic build seemed to explode with growth, every muscle inflating with precision and force. His traps rose like mountains on either side of his thickening neck, a satisfying ache accompanying their ascent. His deltoids rounded out into boulders of power, the sensation of expansion so vivid it was as if he could feel every fiber weaving itself into perfection.

His chest expanded rapidly, each pec growing fuller and firmer with every breath. The weight of his growing torso was intoxicating, a satisfying heaviness that made his heart race. The sound of tearing fabric filled the air as his shirt gave way completely, revealing a torso that looked like it had been carved from granite. Julian’s arms thickened to astonishing proportions, his biceps swelling with layers of dense muscle. The skin stretched and tingled as veins crisscrossed their surface like rivers of liquid steel. His triceps flared out behind his arms, forming a perfect horseshoe shape that screamed power. His forearms grew massive, thick cords of muscle standing out beneath his skin as his hands became larger and stronger, capable of gripping with inhuman force.

His abdomen rippled as a perfect eight-pack emerged, each individual muscle sharply defined and glistening with the faint sheen of transformation. Julian’s obliques carved themselves into his sides, their chiseled lines accentuating the symmetry of his torso. His thighs surged outward, the fabric of his shorts shredding as his quads became massive and powerful. His hamstrings rounded out behind his legs, completing the transformation into tree-trunk-like limbs. His calves bulged and flared with every step he took, their size and shape surreal, like a sculptor’s masterpiece.

Julian’s height increased alongside his muscle mass, his frame stretching upward to accommodate the overwhelming power coursing through him. Every inch gained felt like a release of pressure, his body becoming more complete, more powerful with each passing moment. He clenched his fists, marveling at the sheer strength he felt in every fiber of his being.

“This is insane!” Cooper shouted, his voice deeper and more resonant than before. He twisted his torso, watching the way his abs flexed and moved like living steel cables. “I’ve got muscles! Real muscles!” He flexed his arms, the peaks of his biceps rising to impossible heights, and let out an incredulous laugh.

Julian ran a hand down his chest, feeling the unyielding hardness of his pecs and abs. “We look like gods,” he said, his grin widening. “I mean, look at us!” He crouched down, gripping a boulder with both hands. With a grunt, he lifted it effortlessly above his head, the veins in his arms and shoulders bulging with power. “This is incredible!”

Then they both realized that, they weren't alone in the room... They turned to Blake, trembling in fear at the newly made giants before him.
