Mary had the perfect idea, giggling to herself she shut the door to the bathroom, two vials clutched in her hands.
"I'm going to have a big surprise for you Jess, just give me a minute to get changed", Mary called through the door. She popped the top off of the vials and downed half the dragon vial and then, with the slightest hesitation, the whole male vial. If she was going to try this, she was going to go ALL the way.
Almost immediately she felt a warmth flush through her body as the changes began.
Mary watched silently as her arms began to swell with muscle, heavy black scales pushing out as the skin stretched and changed. Her hands grew thicker and heavier and long sharp claws replaced her fingernails.
With a groan her chest barreled outwards, her breasts being swallowed up by masculine pectorals. Almost instantly thick grey armored plates grew out along her stomach and chest, sculpting it into male form.
Next Mary watched as her legs thickened undergoing the same process as her arms. Her feet shifted and she had to catch herself on the counter as her toes merged into a thick three-toed W-configuration. Her heel lifting off the ground forcing her to stand on what used to be her tip toes. Next a thick tail began to push out from her muscular rump, quickly growing long and dexterous. Mary could feel the incredible power in it as she moved it back and forth and the spiked tip whisked through the air with a satisfying weight.
Without thinking about it Mary's hand crept down her stomach, rubbing over the thick plates and tracing their outlines with her claws. As her hand reached the area where her pussy used to be she shuddered in pleasure. The scales were much more sensitive down there, and she could feel two large globes resting just underneath the skin, leaving slight bumps in her otherwise smooth crotch. "My balls" she thought to herself with a smile.
She continued to stroke her changing crotch as she felt neck elongate and thicken with muscle, the tough scales following soon after. She closed her eyes as she felt her face push out into a muzzle, her tongue lengthening and exploring her new mouth as it filled with razor sharp teeth. Long curving horns swept out from the back of her head as the last of her hair fell out and was replaced by a crest of sharp spikes running down her neck and back.
A pressure in her shoulders began to build as another set of arms began to push out from her back, the hands long and spindly looking. In front of her eyes the new wings grew larger and more muscular, thick but flexible webbing stretching between the fingers that gave them structure. They were far too large for Mary to stretch in the bathroom but they were comfortable enough tucked away behind her.
