Eric easily lifted the 400 pound man in front of him up. The sheer strength his newly grown body possessed excited him, his 11" dick bobbing with delight. Almost automatically, Adam leaned forward and the stubble on their respective chins brushed against each other roughly. This was the first time Eric had made out in a long time, nay, ever. But the smaller muscle monster made it easy. Eric's tongue probed Adam's lips and the young stud let him in. Eric easily held the smaller man aloft, Adam slung his arms over Eric's boulder-like shoulders and his thick legs wrapped around Eric's waspish waist. It was clear to the new giant that the younger man was clearly skilled at pleasing a bigger man.
The bigger man slid his pre-sputtering meat right into Adam's waiting ass, no foreplay needed. Eric was surprised, catching himself mid-thrust realizing that it shouldn't have been this easy. A big grin grew across the hulking scientist's face as Adam's cheeks flushed red and his sharp, handsome gaze wouldn't meet Eric's.
"Someone does this often," Eric snickers.
"Shut up," Adam growled, embarrassment clear on his face. The young stud then screamed as Eric responded with a forceful thrust into him, the bigger, older, stronger man crushing Adam into himself. There was no contest as to who was the more powerful man.
Eric grunted lowly as he had his way with the musclebound Adonis. He could feel Adam squirm as he took him, the lesser man yowling as he was bred deep by the new big man on campus. Adam was taken by how adept Eric was to his new power, how much the former dweeb took control. Crushed to Eric's chest, Adam moaned lowly as he came, his cum splashing into the canyon between Eric's pectorals, his penis massaged by Eric's huge chest and abs. Moments later, it was Eric's turn.
The once-tiny man whooped lowly, the whole garage rattling as the huge 600 pound beast of a man unleashed a torrent of his superior seed into the naturally born giant. It was a Pyrrhic victory for Eric, to dominate the progeny of the man that had dashed his dreams. Eric's eyes rolled back in his head as his pornographic fuck-stick continued to spew more and more of his jism into the lesser man, the most powerful orgasm of his life taking over. Minutes pass and his bull-balls finally spent, the titan fell to his knees, sending the smaller giant sprawling across the floor.
It took Eric several more minutes to recover from the most incredible afterglow, a wide grin spreading across his face. He stood and sauntered slowly to the mirror he had on the far wall. He looked at his few form, feeling his cock spring to attention, all 11" of it liking what he saw. He was a god among men, so tall and imposing, not many could claim to be 7'6", and less could claim to sport such large equipment... and even less to be built like a heavyweight bodybuilder.
But then a frown spread across Eric's face. That was it? At 7'6" and weighing a colossal 600 pounds, Eric was nothing more than a heavyweight bodybuilder scaled up. His 30" biceps were immense, his 70" chest titanic, his 40" quads the envy of all, but on his tall frame, it looked almost... mundane to Eric.
He knew of men with bigorexia, but never did he think that a body like this would look... so small to him. He cursed Steve under his breath, that man had changed everything. He had given Eric a taste of what -BIG- actually meant. And Eric... wanted it more than anything.
The former-scrawny scientist turned to look at his machine and let out a low, rumbling laugh. Adam was busy fiddling with the machine, a look of frustration on his handsome mug. Eric's grin grew wolfishly as he approached, a manic look of amusement on his face.
"I won't fall for that again," Eric flaunted, flexing his muscles playfully. "I've upgraded the machine to only work at my command." He grabbed the smaller man and tossed him across the room, cracks forming on the drywall as Adam crashed into it.
"Are these the settings you wanted?" Eric taunted, looking at the numbers Adam had put in. He flashed a knowing smile as Adam began to recover. Eric pressed his thumb onto the display, his fingerprint registering on the system and the lights of the machine came to life.
"No!" Adam whined, his hand outstretched, hoping to get any little stray wisp of energy that was now blasting its way into Eric's body. He watched in horror as Eric's rumbling laughter grew even deeper, now resonating the whole room with his authority. If Adam had to look up before, he had to crane to see over Eric's massive pectorals, the nipples now eye level with him. The beast of man stomped as his muscles grew thicker, even in comparison to his new height. His physique morphed into something greater. Even if he was the same height as Adam was now, Eric's muscles would dwarf his, looking at least half again as thick as the young stud's.
"Ohhhh, you like 'em big, don't you, boy?!" Eric howled in laughter as he felt the last bit of the transformation focus on his crotch. Eric pawed at himself lewdly as he felt the appendage attached to his pelvis grow so thick he now needed both of his giant hands to get around it. His balls bloated with his seed, growing from the size of large goose eggs to peaches then to obscene, mango-sized testes. Steam sizzled off the surface of his skin, now smooth like Adam's, his grey hairs turned back to the color of his youth. Eric slowly, precariously made his way over to Adam, slapping the young stud across the face with his superior prick, having doubled in size and girth, a 22" scepter of power fitting for a living god.
Eric couldn't wait...
