You go to respond when a familiar tingling sensation overtakes your body. The tingling slowly becomes burning until it feels as though your whole body is engulfed in flame. You scream out, but no sound exits your mouth.
The young attendant stands stiff in shock. She gasps and puts her hand to her mouth in surprise. Her eyes do not blink as she backs against the room's walls.
Once again, you fall back against the wall from your frozen state, and your ass slides down into the corner of the seat and the wall.
There is no one-step-at-a-time growth with this go around. Instead, everything expands at once; your legs creek forward and fill out even further, giving your already massive calves a menacing look, and your thugs rip the bottoms of your skin tight briefs, which had been returned to your waist. Your ass then busts out the back, growing so much to cause a noticeable difference in your view, and leaving just the front to "cover" your massive salami.
Your abs, pecs, and back all grow at once. Each individual abdominal muscle becomes overly-prominent under your spandex shirt, at least three inches wide by and inch and a half tall; a new set of two pushes forward infer the shirt, leaving you with the most shredded of 10-packs.
You feel your pecs heave forward, as before, and look down to see them roll forward out of your chest. They have grown so much that you know if you could look down beyond them before, you sure as hell can't now. Likewise, your nipples tingle and stretch; they are at least two inches in diameter, if not more. Your pecs must be the size of cantaloupe melons by now. This final chest growth rips down from the collar of your shirt to the very bottom hem.
The air, cool and conditioned runs down your chest, causing your nipples to tangibly perk forward and your pecs to simple from goose-bumps. You let out a moan and try to reach for your lustful globes, but are still restricted from the strange freezing.
Your shoulders and back also bunch and expand outward. Like before, your back itches itself as it moves along the wall. With each burning surge, it grows wider, and you gauge it's progress by the angle of your arms, which are pushed upward by the strange growth. Your neck growth accordingly, and you feel your vocal cords stretch and change at this time too. Likewise, your shoulders mound onto of themselves, leaving more whole cantaloupe Mellons on your body.
With the flames in your arms, your body moves on it's own into a double bi flex; as you flex, they grow incredibly massive, to the pinto where they look like over inflated footballs, and your tris expand as you stretch your arm out, leaving horseshoe shapes comparable to parade float horses shoved under your arms.
As this all over growth comes to an end, you feel as if your testicles have been run over by a dump truck. You once more try to scream in agony, but cannot. The surprise from the air on your chest is now at your crotch, and your perifferals give you enough information to tell you that your already obscene looking piece of meat has stretched well past 12" soft. You look down and see that the last remaining scrap of underwear has been removed from your body, leaving you completely nude.
Suddenly, you feel slow, for a lack of better terms. The feeling is as if your brain was suddenly crushed into a tiny pea. You moan, as the feeling of numbness tingles at the edges of your mind.
You judder and fell more tingling all across your body. Hair bursts forth from nearly everywhere: face, arm pits, chest, cock, and shins all are now much harrier. An incredible odor suddenly fills the small confined space. It is the smell of a man, a strong and sexy god of man.
Your limbs suddenly droop, and you regain control of your body. A faint gasp alerts you to the girls presence. She has not left, but it seems she cannot stop cumming. She collapses in a heap, visually unconscious but still cumming.
"Fuuuck..." You manage to blunder out in your deep base. "That bitch was good..."
You look in the floor to ceiling mirror, and are amazed by what you see. The definition and image of manliness, as if pulled directly from the dictonary, stands before you. A man at least twice the size of a professional bodybuilder is reflected in the mirror; his muscles both incredibly huge and intensively shredded. His cock also sets him apart, not being shrunken by years of steroid abuse.
With your heavily limited mental capacity, you reason that the pilly-mabob has grown you into a 30 year old man.
