John leapt to his feet in triumph, his boner slapping his abs. "So what do you win," asked Dan, eyeing his oldest brother curiously.
Suddenly, John began to grow. The growth wasn't concentrated on his dick, his muscles or his height, but all of it. His entire body expanded, his head reached for the ceiling as his muscles exploded with size. His cock pulsed longer and thicker, his enormous balls being lifted by his expanding quads. His back flared and widened, rippling as pounds of muscle was packed on. John's arms stretched as they were pumped up with huge bulges all along their length.
By now he had passed Billy in height, once again becoming the tallest of the three. In addition he was now the buffest and certainly best equipped, sporting his 16 inch erection which was still swelling. If Dan's little five incher had become a foot long sausage, Billy couldn't imagine how big John's impressive 10 inch cock would grow.
"Fuck yeah, I'm so huge and I'm still getting bigger." John flexed both his swollen arms, easily twenty-five inches of solid muscle. "Look at all this muscle, I'm loving it." Even his voice sounded deeper.
His gigantic shoulders pressed further outward, anxious to get away from his thickening traps which were engulfing his neck. John's pecs exploded to a foot in front of his face, nearing the size of pillows with bottlecap-sized nipples.
Even his face changed, from the attractive jock John became a drop your pants gorgeous model, with a large angular jawline and pronounced cheekbones and piercing blue eyes.
John's head passed seven and a half feet and he looked down on his smaller brothers with a grin. "Don't you guys fucking love this. I'm actually hulking out. I'm a musclebeast." John grabbed his tremendous cock. Even with his large paws he couldn't completely grip the thick shaft. Suddenly, John's clean-shaven face erupted with a dark 5 o'clock shadow. Dark hair sprouted along the deep valley between his pecs and spread down to his 10-pack of sickeningly defined cobblestone abs. A large sexy, treasure trail branched down to his expanding bush. Thick leg hair covered the tree trunks that supported his massive frame. Hair coursed along the thick cords of muscle on his arms.
Billy began to wonder how many transformations John would get. He looked at the screen and saw a list. Awards won Height, muscle, size, hair, face, orientation. There it was again. Orientation. Billy was beginning to suspect its effect as he gazed in horny rapture at his gigantic older brother. It meant sexual orientation, and since all three had recieved it, they were all now gay!
When John's incredibly growth finally stopped, the sexy titan stood at 8'2" with 500 pounds of sheer muscle with a masculine coating of hair and a two foot erect cock with softball sized nuts.
