As they chatted, Danielle wished her co-worker would just go feed the cats. She could feel something building and didn't want someone knowing anything quite yet.
A warm wave surged over her body. She could feel her skin tightening, as more body fat melted away. She could feel her tits hanging unsupported, free floating inside the now much too large cups of her bra. One shoulder twinged, then the other.
Most of all the heat settled into her clit. She could feel it throbbing in time with her pulse, quickly beginning to press against the inside of her panties.
Her mind raced. She was growing a cock right in front of Alana and the girl seemed oblivious. Then it hit Danielle, with her enhanced vision, she hadn't turned on any lights. Alana probably couldn't see much of anything, especially right after stepping inside on a sunny day.
Danielle's jeans were now seriously constraining in the front. She could also feel the straps of her bra digging in, as her torso expanded under them.
Mercifully Alana seemed to get the hint that Danielle wasn't feeling talkative and headed out, sipping her contaminated coffee as she left.
Danielle went into the bathroom and took stock. It only took one glance to confirm that she was now a shi. Pushing out of hir waistband was the tip of a black skinned cock. Pulling down hir jeans, shi found hirself to be the proud owner of an eight inch penis. It was human shaped apart from the inky coloration, though inexplicably there was no foreskin. Hir groin had been overgrown by thick black fur. It ended a few inches above the base of hir manhood, and trailed halfway down the inside of hir thighs. Below hir cock was another new addition, a full scrotum covered in the same black velvety fur. Lifting them shi saw hir labia had turned black to match hir new equipment.
Stripping fully, shi found that almost all body fat had vanished and had been replaced by easily 30 pounds of additional muscle beyond what shi already had possessed. Hir abs were rock hard and perfectly defined, Danielle could make out hir obliques flanking then as well.
Hir ribcage had broadened, and hir breasts were down to probably a B cup, awkwardly sitting on top of the emerging pectorals bulging forth under them.
Danielle quickly dressed again as best shi could, and went to check the cameras to track how soon Alana would be returning.
