Dustin watched this transformation in awe, in awe of his brothers powers. "hey dustin, do wanna be bigger?"
"shit, ty , look at me, im allready huge!"
Dustin was big , but in that instant ty concentrated on making him even larger. He thought for moments about how many pounds and how much mass he could pack ontop of dustins allready large build.
Dustin was overwhelemd by that feeling again
"T--y, tyyyy... imm- ...all - all-reaaady biiig" Dustin words stumpling from his intense pleasure overwhelming him.
In that instant Dustins large pecs began to swell, larger and larger. They began slowly pumping larger and more round. the rest of his body kicked into a testosterone overdrive as ty caused dustins whole body to enlarge, his allready large frame expanding out, larger and more full, Dustin was turning into a muscle freak! His biceps pushing outwards thickening like inflating basketballs stuck under his skin. Dustin's package grew still larger, his ball growing to the size of melons, sending great waves of testosterone flowing though his body. Chest hair sprouting between his two mountanous pecs.
Dustins massive chest was still expanding outwards, pushing and pushing out and out. By now his body was much bigger than any bodybuilder, and he was still growing! he now stood there much bigger than ty,and even starting to get taller too.In moments Dutin was towering over the allready tall ty. Dustin stood near 7'5" and could have easily weighed in at 600 pounds or more. Everything on Dustin was oversized now, his shoulders a good 6 feet across, a chest easily 150 inches around (if not greater) and abs that formed a 12 pack!
not to mention his cock and balls 10 times too big.
"dude, look at me, im turning into a massive freak!" Dustin said, his voice now deeper and more masculine. "this is awesome!"
Dustins growth finnaly stoped, leaving him with a body so un-naturally large that he wasent sure if he could fit though door frames anymore. he didnt know how he could even fit into regular buildings, much less any car. Muscles buldging out to size bulk that there was no way any shirt could fit on his overgrown body!. he was just too big for them now!
"i bet my girlfreind wont think im too small now!" dustin said with an air of confidence.
"no, i guess not..."
But as soon as Dustin had attracted his attention, it was gone, now ty was once again looking At the gym. nobody had noticed Dustins incredible transformation, because ty made sure they wouldnt. But now ty had something in store for the men in that gym.
