Before Brian heads to the gym he likes to do a little flexing infront of his full length
mirror while wearing his white boxer briefs. Just to notice a before and after of his
workout. Walking over to the mirror Brian stumbled and spilt a bit if his shake on his
briefs, no problem he thought to himself I'll wash them later. Brian began posing infront
of the mirror, pumping his biceps and flexing his pecs, something caught brian's eye
as he posed he noticed his muscles seemed a bit more bulgey he kept flexing and
could literaly see his muscles growing, was he imagining this, Brian looked closely at
his bicept and cocentrated, it bulged out slowly, Brian now had ideas of what he
can do. Brian made a double bicept pose and his muscles blew up beautifuly. Brian
now watched as his pecs pushed outward his stomach harden and ripple into a hefty
eightpack, his quads inflated and his calves tightened he grew taller and his hands
and feet expanded even larger.
Brian now stood at about 6'6" with around 300lbs of muscle. Brian marveled at his size
but something was missing he couldn't see past his pecs so he turned toward the
mirror and noticed something wasn't proportionate. He then focused on his package
and watched it stretch out the tight fabric of his underwear, he continued to expand his
new endowment determined to rip his briefs to shreds his bulge was completley
obscene his dick pushing 15" soft and balls to match it seemed the underwear would
never tear. Brian ciesed the growth and began to consider the causes of his new
ability, ! The Muscle Maximizer ! He thought about it for a minute, when he spilled the
shake on his boxerbriefs it must have allowed them to fit his body at what ever size he
was at. Brian grabed the straps of the briefs with his thumbs and stretched them
outward the briefs spread out as far as his arms could stretch. Now Brian wondered,
what to do next.
