Matthew already dreamt of being a jock. A muscle beast that can dominate anyone, in life and in the bedroom. However he was scrawny, weak and barely had any meat on his bones.
It was Mathews first day at the gym and he was highly intimidated by the mountains of muscle that was all around him. Men on all different kind of machines pumping and lifting their weight, flexing their muscles and exposing their perfectly carved abs, pecs and biceps for all to see. Getting approval from their fellow gym bros.
It was such a exciting sight to see, so exciting that it gave him a boner that was quite visible. Matthew hurried to the changing room hoping noone noticed his embarrassment.
When Matthew entered noone was inside the room which was lucky for him, he walked to the furthest row of lockers trying to hide so he can keep his boner down. After keeping his dick uncontro he noticed there was a jockstrap laying on the bench, untouched but filled with sence of desire that Matthew could sence but too sure what it was yet and also filled with semen. Mathew inspected the jock and gagged, the jock had a strong musk emmiting from it. There was also a huge cum stain spread all over the inside of the jock, still wet reeking of whoever ejaculated in it previously, even though it was disgusting to anyone else Matthew felt more drawn to the undergarment as if it was calling him.
Without a second thought he stripped off his shorts and underwear and started slowly placing the jockstrap on his body but once the jock was on there was no going back. The jock felt quite comfy but also a bit uncomfortable due to the cool sperm that is now spread all over Matthew cock and balls. The feeling was quite strange but felt right.
All of a sudden Matthew could feel a warm tingle flowing through his body but his body started heating up more specifically in his arms which were growing and becoming stronger "Oh god! What's happening to me?" A sence of panic appeared from this unusual display. His shirt started to rip slowly around his arms as his biceps grew bigger. Next his torso was heating up feeling as is his stomach was on fire as abs started to form that were now exposed as his shirt fully ripping off his body. He was now standing with nothing on except the jockstrap wrapped around him changing him slowly into a muscle gym bro beast. Matthew closed his eyes, grunting at the pain coursing through his body as he started sweating from the internal heating
We walked over to the furthest shower to continue further with the transformation in private.
"Hungry" Mathew groans. He opens the jock and scoops the semen that was originally in and sniffs it again closer to his face than before. This time he enjoys the smell and even licks the splooge from his hand as well as his fingers with a satisfying pop from each cum coated finger, loving the salty sperm was in coating his mouth.
The taste was making him pop a raging boner that was very noticeable from his new 12 inch cock
Semen flew up Breaking through the jock
"Hehe huge muscles" he chuckles as he flexes
He stepped out of locker room a new man with new desries and we wasn't going to stop now. Matthew had previously noticed another guy who just like him, weak and small but not anymore. He approaches the timid man minding his business when his big frame overshadowed the man.
"Hey bro, wanna get big?"
Hope you all enjoy my first story! :)
