Mom and son are stranded at the airport.
She cracked open one of the twenty ounce bottles and eagerly guzzled the new and improved formula. She was half way to the bottom when she remembered that a dose had been significantly decreased ot eight ounces. Oh well, might as well finish, right?
The thick, minty fluid burned in her throat as it flowed down and that heat only spread as her body began to throb. She slammed the empty bottle on her desk and let out a sigh. She shrugged out of her coat just as her arms began to grow. Even through her fur and sweater, it was obvious she had gained an inch of bicep already.
A powerful throb made her double over. She gripped her desk with hands that were growing larger and more paw-like by second. Her thickened digits crushed the plasterboard as her forearms twitched and swelled a considerable amount. Her biceps were next, the already well developed muscles gaining inch after inch with each ragged breath.
The horns from the dragon bits of her DNA began to grow as others broke through the skin on her forehead and at her temples. She felt more than heard a grinding as her skeleton began to grow to accept all the new bulk. Her back broadened, the stretchy wool expanding with her. Her stiff skirt was not faring as well with other parts of her widening. The sound of cloth tearing mingled with her gasps as her hips, ass, and thighs each pulsed larger and larger.
As her muscles grew and her frame lengthened and her body tightened, she felt a pressure building between her legs. It occurred to her that taking this much AdonisMax, having this much hyper-powered testosterone burning through her system, could have an interesting side effect on her already altered sex.
The throbbing in her body grew worse. The heat had her panting. Her elbows buckled and she dropped to one knee, destroying what remained of the skirt in the process. With her arms crossed on the desk, it looked like she was holding on for dear life as a severe overdose of the formula wreaked havoc on her body.
She could feel her dick growing now, the sensitive organ straining her sheathe, stretching it out. Her length rubbed the fur of her thighs, sending small shivers of pleasure up her spine. Her balls, too, felt like they were inflating. A hand reached down to confirm and she could not help but grin. Her dick was already several inches longer than before and quite a bit thicker. Excited, she gripped the pulsing shaft and felt another, more intense jolt of pleasure up her spine. Stroking it now, she could not stop from moaning as it grew in her hand and her balls forced her legs to spread.
With each pulse of her racing heart it felt like every inch of her expanded as fire surged through her veins. Her back had gotten significantly broader. Adding the curve of her deltoids and the developing valley between her traps it was no surprise that rents had started to form in her sweater. Pectorals overwhelmed her chest, burgeoning muscles pulling her cleavage tighter. Lats pushed her arms out even as her biceps passed fifteen inches.
The pressure in her crotch had not lessened even as her erection began to smack against the underside of her desk from her frantic masturbation. Her swelling knot pressed into her sheathe. It had to be the size of a grapefruit. There was a gurgling inside her. Her sack felt tight. A slight pain as something brushed her shaft from the inside. With a groan that became a low scream, a second cock emerged alongside her first. Her balls grew explosively, reaching the floor a moment later.
Her poles were slick with pre-cum and she would have kept jerking off had it not felt like she was being strangled.
