Jeff had just played the hardest game of his life, which finally ended with the Cardinals
winning by two points in the 13th inning. While the team was celebrating in the locker
room, several kids who had won a chance to meet the players came in for their prize.
Jason, a 12 year old, came up to Jeff and stuttered out "hi", while in awe and amazement of
his hero. "So kid, you want to play in the majors someday?" said Jeff, while winking to the
kid, watching the kids eyes grow wide and say "yeah!". "Well, why don't you take my shirt
as a souvenier then, I have another change of clothes here," while he handed it over, "I
look forward to playing with you someday."
Jumping with joy, the kid took the shirt and ran out the locker room with excitement,
ready to show off his new shirt. He stepped into a nearby bathroom, where he locked
himself into a stall and put on the shirt; little did he know what would happen next.
Jason started to feel weird - his heart was racing and he was having trouble catching his
breath. The t-shirt began to change slightly, he noticed that Jeff's number 23 changed on
the front to number 45; meanwhile, he didn't notice the last name changing to "Beck" and
the number changing there as well.
"Whoa," Jason mumbled as he lost his balance and braced himself against the stall wall.
His legs had just began to grow, cracking and healing quickly as he gained height. From
his height of 5'2", he's growing inch by inch...5'5"...5'7"....5'9". As he keeps growing, his
shorts expand and change into a red and white pair of mesh basketball shorts. Next, his
torso began to exhibit signs of growth; Jason's back began to crack as his spine grew and
lengthened. 5'11"...6'2"....stopping at 6'4"....with the t-shirt enlarging slightly to fit as
well.
Jason now begins to feel heavier as the rest of his bones catch up to his body. His arms
lengthen several inches while his feet grow from a size 6 to a size 13...and his shoes creek
and expand into a pair of red and white Adidas crosstrainers.
His chest next began to grow breath by breath, swelling to a proportion that stretched the
Cardinals logo just as it had on Jeff. His nipples grew slightly and began to point
downward, while his abs began to develop into a well developed six pack.
Next his arms began to swell, quickly becoming 20" guns ready to hit balls out of the
park. They stretched the shirt so much that the sleeves began to disappear, turning the
team issue t-shirt into a sleeveless. Jason's legs started swelling as well, becoming
extremely large and powerful for running the home runs he will be known for.
Jason's head began to change, with it enlarging slightly to become proprotional to the rest
of his body. Meanwhile his face started to take a more masculine appearance with a
sharper jawline. His eyes then changed to a bright blue while his hair pulled back into his
head slightly and became a blond buzz cut. A well groomed mustache and goatee then
appeared around his mouth while a Cardinals hat appeared on his head.
While the number 45 was tattooing itself to his left arm and a tribal armband to his right,
Jason grabbed his head as he felt his whole body sting with pain and pleasure as he was
adapting to his new life and learning how to play pro ball. Jason had just realized he's
now 23 and just joined the Cardinals as a designated hitter when the bathroom stall door
busted open with Jeff standing outside.
"I thought you might like this," Jeff said as he approached Jason and put his hand on
Jason's crotch, "but one last thing remains dude." Jeff then began slowly massaging
Jason's boy sized cock, which then began to grow inch by inch....4"....6".....8"....stopping at
an easy 11" and as thick as a beer can. Meanwhile Jason's ball sack began to sag as his
testicles grew larger and larger, filling with testosterone and cum.
Jeff and Jason then began to kiss and make baseball jock love in the bathroom stall.
