"...this must be the place" said Sean, looking at the big building in front of him.
He had gotten an ad in front of his home some days ago, announcing a new gym called "Manly Gym", only for men, and where it was "guaranteed to make you fit, or beyond"
The Ad only had the address, the phone number, and some images of the inside of the building.
The first time he saw it, he was gonna ignore it, before he realised it had been a while since he had worked out his body, aand was starting to get fatter. So he chose to go one of his free days.
And there he was now, standing in front of the building, with the name "Manly Gym" in front.
The door in front of him was transparent...or seemed to, at first glance, as he could only see his reflection, and the crystals at the side of the building were completly black.
This gave him a bad feeling, but also some anticipation.
But before he could open the door, a voice talked to him.
"YO! A CUSTOMER, HUH?"
Sean turned around, a saw a man coming to him from one of the sides of the building.
The man was big all around, and seemed that his belly was about to burst his shirt. Sean found this quite funny, but tried to hide it.
Eventually the man got closer.
"Yeah, sorry about that, but you can't use this door, heh. You need to enter through the back"
This confused Sean for a bit, but he agreed to do what he said, the man smiled, and guided him behind the building.
Inside, they seemed to be on some office.
"All right" the man said, sighing, and sitting on a desk not so far away from the door. "Now, tell me your name so i can look you up"
"Sean Patterson"
The man smiled, and started to search on his computer for the name.
"Let's see...All right mister Patterson, here you are. The locker room is around the corner, and the main room is just to the right of it. You can start to use the machines whenever you are ready!"
Sean thanked him, but as he went away, he could heard the man chuckled.
...
Sean entered the locker room, and met with a man inside.
It was an athletic man, and was naked, holding some boxers on his hand.
"Oh, a new user. Been a while since we got new people, hehe"
Sean tried his best to not directly look at the man's dick, but it was hard.
"Heh, you don't have to hide your excitement, buddy! We are all men here y'know" he said, softly grabbing his dick "But meh, i gotta get back to my workout, so see you back there. Maybe you would like this place, hehe..."
The man walked outside, confusing Sean a bit about what he said.
...
Now he was ready to work out. Wearing some shorts and a tank top, he went into the main room, but stopped on his tracks at it.
There were like 15 guys, all of them were barely clothed, mostky in their underwear, but still were working out. The air smelled like sweet, and somewhat like cum.
Normally Sean would have found the situation awkward, but something told him this was normal. So to be safe, he tried to move close to one of the running machines, before he felt an arm on his shoulder.
"Hey, pal. You new around here?"
Sean turned around, to find his eyes meeting with some sweaty abs.
He looked up to also have his view covered with some pecs.
It was a 7 feet man, only on his underwear that seemed to be very tight.
"Y-yeah" Sean muttered.
"Good!, new people around here is always fun. Why don't you try the weights over there?, i bet something cool will happen!"
Sean was confused by the man's attitude, but he was already too far into this weird place.
He walked to the weights, and lifted them, he did a few time, slowy getting tired, before he droped them.
"Hehe...here comes the fun part" said the man.
Before Sean could say anything, he felt strange on his arms and chest, before a wave of pleasure attacked him, making him lose balance.
"W-wha..." he moaned, as his arms started to expand with newfound mass, become strong and solid.
Soon so did his chest, becoming more defined, as his pecs swelled and bulged, become more strong.
Sean was very confused, and scare, but the sudden pleasure had him a trance.
The man, and others around him, just stared, as Sean also started to grow on his abs and legs, as more moaning came out of his mouth, and his pants get wet with pre cum.
Eventually, the growth stops, and Sean lays on the ground.
His body was now one of an amateur bodybuilder, his arms, chest, and legs feeling newfound power.
"W...w-what the..." said Sean, exhausted and confused.
The man laughed, before he screamed "WELCOME TO OUR HOME, SEAN!, THE MANLY HOME!~" he said, as the other men started also cheering and screaming his name.
Sean slowy got up, first confused, but then smiling as he sllwy understood what had happened.
"B-but... Is this..."
"Real?" said the man "Heh, very real, buddy!" and now comes the best part!"
Sean was confused, before...
