"A 35 year old human male is out on an afternoon walk..."
"Would you like to view the transformation? Yes or no?"
A choice appeared, and Martin hummed as he considered the thought in his mind. Why not? He had the time, it would at least confirm nothing was smoke and mirrors anyway, and with that, the confirmation button was pushed faster than ever as Martin watched in eager anticipation for the accompanying changes. He looked on as the woman before, and immediately stopped as though something was wrong, and froze in the middle of her path.
Furrowing his eyebrows, Martin nearly looked back to the app for answers, when he noticed the woman grunt, her voice a tad deeper as he recognized the transformation beginning. The lithe, smaller muscles had begun to shift and bulge comically of her body, the most drastic being her back, her right side enlarging brutishly from the pink tank top and flexing as bumps became ridges and lats spread forth like wings. The other, not to be left behind, found itself swelling to similar proportions, her back threatening to swallow the newly tiny tank top that was beginning to tear as muscle was being chiseled from soft fat.
As if in a trance, the woman stood still as she groaned pitifully, voice lowering even more as she clutched her stomach, the shoulders beginning to broaden and round rather tantalizingly while her arms began to fill out, biceps forming respectable peaks while her neck seized forward and created smooth, mountainous slopes. Triceps widened as she shivered in place, her soft, dainty hands had become rough, nails having lost their paint, and thickened further as callouses settled onto the palms.
Her dark yoga pants flared out from the bottom pant legs, the fabric changing as the length had shortened almost drastically, Martin beheld as thin legs grew into impressive calves and defined thighs which had toned... then bulked up as the pant legs slid up the musculature. It settled on the woman's larger tear shaped quads as it caved slight V's into the sides and the hem became light grey borders to the newly made short shorts. The woman's gasps grew faster and more primal, the groaning on par with Martin's own as her neck tilted back, an prominent Adam's apple beginning to expand as the changes followed.
She greedily gulped air as her once supple breasts lost some of their roundness and flattened into her chest, before expanding and firming into a new shelf that heaved her body forward, hands groping the nipples as the pecs bounced and made a jutting cleavage. As if on cue, her once pliable stomach sucked in, fat and muscle spreading the smaller waist into a thicker proportion to uphold the changes the body still yet had to process, firm abdominals burning the excess fat and creating the cobblestone path a thickened hand had felt up.
Hair found its way dusting the key areas of the woman's newly crafted physique, betraying her once hairless and heavily trimmed body as a treasure trail lead down to her own prize. Not to be forgotten, the undeveloped posterior she once owned had begun to balloon as muscle and sinew found the way to one of the largest assets beyond her rippling chest. Bulging, it shaped itself rounder and thicker as it supported the larger frame and piston-like movement her hips were making, the entire lower body radiating heat as the application continued its machinations.
The woman grunted, a rough hand flying to her face as her jaw cracked and jutted out farther than it once was, a chiseled and square chin that held a faded stubble which quickly grew into view. Unable to resist her body's warmth and primal calls, the changing woman whimpered as she felt a stirring in her loins, nearly crying out deeply as he felt his body come to fruition. Changing locations from his handsome jaw, the man felt his crotch enflame as his dug into the shorts, massaging his growing appendage as what was once a wet slit had quickly extended into a throbbing member that did not hold back from showing its new mass.
With another whimper, the man clutched his mouth in vain as he continued to stroke the swelling cock that threatened his shorts and newly fashioned thong as his nose shifted outwards and his eyebrows sharpened to enhance his already masculine visage. Once longer, brown hair had shortened into his scalp as it styled into a flawless faded undercut, darkening into night black while his cheap earrings were replaced by sparkling studs. Knees buckling, the newly forged man rumbled as he came, the entire climax cementing the app's work.
Martin watched intently, as he saw in fascination that the large load over the man's shorts dissipated, the throbbing tool easily sliding back into its pouch as the man began to stretch, unconscious of his previous existence as a woman. He touched his toes, rolled his massive shoulders back, and ran a rough hand over his hair before noticing Martin's stare and winked flirtatiously. Martin could hardly believe his eyes, more so that the changes hadn't even been reflected in the mind of the man who now was pulling off his sweaty pink crop top and throwing it over his deltoids and basking in the sun's glow, his entire physique exemplified by the rays. The muscular man chuckled, flexing his biceps and finding his phone to capture his workout look, a soaked pink and white headband adorned his forehead as he completed a most muscular to Martin's excitement.
He was absolutely gorgeous, and even more interesting: He was a result of the app.
Martin gulped, eyeing the application as it spouted a new sentence from the previous subject:
"The 35 year old male bodybuilder loves attention from onlookers."
With how the app worked, it would seem that there's a lot of variables to what the changed sentence interprets for the subject, but with how well this turned out to be... It was hard not to want to experiment further with what this thing could do.
