"what the hell", looking around seeing all these naked guys in cages.
"what's going o...Agh" All of a sudden the muscle guy you were talking to before grabs you, "agh" struggling "let me go?!?"
"I dont think so" huh? a guy in a white lab coat emerges from nearby with a syringe, moving toward you.
"I hope you're excited. You're going to become the next attraction!" still attempting to escape..."what do you mean..agh...let me go"
"Theres no use" the doc says "oh yes, you'll do nicely, toned muscled body" "What the hell" you think to yourself
"I've been developing a new serum...one that unlocks mans genetic past...and combined it with another hormone to in effect....create the ultimate man....primal, muscled, simian, ....in essence a true Freak!!"
'Agh.....let me go..." you keep struggling but its no use...
The doc comes up and "NOOO...agh...!?!" jabs the syringe into your arm...its contents filling your body....."
"agh...no" still attempting to get away....the muscle guy throws you into the closest cage and locks the dooor.
"LET me go!?...when i get out you'll pay.." banging furiously on the bars..."THers no use...you can fight it all you want.....but you'll give in, might even enjoy it" the doc grins
"fuck....starting to feel so hot.." you're getting totally sweaty...you're tank top is soaked..."yes...mmm" the doc grins...its already starting....
"agh..soo hot in here..." you rip the tank top off...then looking down at your hands and arms...you see veins start to cover them..."agh fuuck....whats happening to...me".....!

"agh....fuucgkkk...becoming freakk...nooo agh.." you double over as your back swells....spine cracking and readjusting....mass pilling on lats flaring out...so thick and freaky.........your torso is starting to look so freaky, out of proportion to your lower half...

"Agh...Fucghkkk yeah.....becoming freak.....not fight..anymore...grrr" you look down as your pecs grow..two freaky swole mounds of massive muscle pushing out from your chest..a deep clef in the middle "mmm... grrr...." you start to bone up as your torso swells...
you can hardly see past your swollen pecs as your abs grow...your tight 6 pack becomming a massive swole muscle gut....totally simain...gorilla like...."mmm become freak...so huge...." you feel your abs as they grow...
"oh my, subject is progressing quickly the second stage should begin soon.." You're legs swell next....becomming massive swole tree trunks....thighs becomming so thick and massive...pushing each other apart..."AGHHHH FUCGHKK..." bones crack as they shift and reform to support your massive torso..pelvis shifting , becomming wider....
"Subject has allmost totally given in...." the doc observes
Your shorts are so strained and cant take anymore...."AGHHh... No NEED GRRRR" and you rip them off exposing your swolen growing primal muscle cock...
"Oh MY..mm...subject has allmost totally regressed..."
"Mmmmmm grrr..." you stroke your muscle cock , as the final changes occur......"AGHh".....your brow pushes out...jaw squares off and pushes out as well....nose flattens a bit.....
A thin layer of brown hair begins to cover your muscles...pecs...arms....legs...totally simain and primal...your arms legthen slightly as well...down to your knees now...Torso totally out of proportion to your lower half...
You stroke your cock and feel your freak pecs as the doc looks in delight "yes...total success....subject has become the perfect cross between neanderthal and overdeveloped muscle freak..." the doc stands there rubbing his cock in delight...
You will make a perfect exhibit to the freak show..."and perhaps even make a freak muscle buddy for you too...." the doc thinking of the surfer guy who wandered off......
