Alex was your average person.
Average muscles, average intelligence, average genitals, average...everything, really.
He was working his body out, trying to break even slightly his "averageness", urt no matter what he tried, he will still have average muscles, not even athletic enough.
" boy, what a day" he said out loud, after pumping some iron.
The Gym was kinda empty that day, so he could pump iron on peace
He went to the gym because of the cold air of the area where he lives.
Even so, he moved to the showers, ready to take a hoth bath, but stopped when he saw a door near one of the showers.
"Hm?, this wasan't here before"
The Door was Mettalic, and was engravef with the words "Sauna of the Gods".
" A Sauna?, huh, i could try this"
He wrapped his short towel around his crotch, and entered the door.
The place was kinda small and comfy enough, Alex choose a "warm" temperature for the Sauna, closed the door, and sat in place.
The place soon started, and Axel could feel the warm from the Sauna, and the cold going away.
"....Mmmgh" Alex started to felt a strange sensation through his body, and felt how the place got warmer.
"I should...go" something was definitely wrong, the place was a lot more warmer, yet when he tried to get up, he saw that his body was a lot more defined.
"what the...hell?" his voice wasan't working completly, his mind was overwhelmed by the weird feeling.
He could see how his body bulged and grew in front of his eyes.
His pecs grew stronger and more defined.
His belly got strong and defined, with a six pack.
His ass, his most important part, inflated, turning into a big bubble butt.
And lastly, he could see his dick and balls enlarge too.
"M-...mOORE!"
He could feel and see his dick get the towel wet with pre cum, and go from 7 inches hard to 10 inches, his balls get 1 inches long, his pecs, abs and his ass grew once again.
He looked like a bodybuilder, with a hand he flexed his newly formed biceps, and enjoyed his transformations like any other.
"This is...Amazing!'
