The drive home for Mary was unpleasant to say the least, even alone. All that Hype, all that Build-up to sprout Fur and Fangs. For what? Utter humiliation in front of the entire class when it failed. Now, she just wanted to get home and be done with the day already.
“Urgh…” The whole fiasco had left a bitter taste in Mary’s mouth and she needed something to wash it out with, but all she had with her was the box of vials she’d brought back with her.
“May as well…” She figured since they hadn’t worked, she might as well use them to at least wash down the bile, the Muscle Growth being the vial of choice.
The long swig did the job of cleaning her mouth out as she shoved it back into the box and pressed on with getting herself home, but not even a minute later, it did more.
Had the Werewolf Vial gone as intended, Mary’s transformation would have begun that night, with the rising of the Full Moon. But now that the Muscle Growth Vial was affecting her, the two separate serums reacted with each other, and it began there and then.
First it was an imperceptible itching across her entire body, the skin appearing to darken, but in reality that was the dark brown fur pushing through. At the same time, her ears became pointed, slowly travelling up the sides of her head to settle at the top, even as several of her teeth sharpened into fangs in a mouth that stretched forwards into a muzzle.
“Stupid Vials. Stupid Brittany…” Mary’s despair started giving way to anger as she continued to change as she drove along the thankfully-empty road, thoughts of revenge entering her mind.
Said anger growing as the Muscle Vial’s effect became apparent - had she been paying attention - with her inflating muscles, combined with her thick fur, pressing against her blouse and pants, appearing to be puffed out. Enlarging feet squeezed into too-small shoes that started to split under the stress. The seatbelt digging into her didn’t help matters any, and with an animalistic snarling growl, all but tore the buckle loose.
And that motion added the last piece of stress that overcame the resistance of her blouse, a symphony of pops that heralded the front of her swollen chest - and even more swollen breasts - taking in the free air with her bra snapping open at the same time.
“THE HELL!?!” Only now, with her arms, thighs, and crotch freeing themselves from their fabric confines, did Mary realise what was happening.
She couldn’t have known how at the time, but her use of the Muscle Vial had permitted the transformation of herself into a werewolf to proceed ahead of schedule. What she did know was the effect it was having on her with her feet now bare, along with her legs, and her arms, and her chest. Pulling over to a stop, the transformation completed just as the handbrake went on and she could take a look at herself.
Seven-foot, maybe seven-three? Extreme bodybuilder shape with arms and legs like tree trunks, black-clawed hands and feet to match. Massive swollen breasts that now pressed into the steering wheel until the seat was backed up all the way. Brown fur all over, and far longer where her hair used to be. In the rear-view mirror, yellow eyes peered back at her.
“It…worked…” Perhaps stating the obvious, but needing to say it to believe it through a throat that deepened and hoarser than her normal tone. “But…”
Mary reached for the box, careful not to grate her legs against the steering wheel as she looked for the Human Vial.
“Where…? Wherrre is it?” She groaned as despite her haste, she needed to be careful, aware that now her strength would almost certainly be much greater, and couldn’t risk damaging the vials, especially now that she knew they really did work.
“No…” Cold realisation struck her hard.
The Human Vial, and the Werewolf Vial.
Both had still been in Miss Ethel’s classroom when she left.
Now she had a real problem on her much-larger hands. She couldn’t turn back without the Human Vial, and to get it she’d need to try and claim it in her current state. If she even wanted to.
“Okay, I can drrive, okayy.” Satisfied she could still drive her car safely, Mary knew she could get back to the school easily enough, and with care could sneak into the class and get the vials back.
As long as they were there, if not, Mrs Ethel would most likely have it, and she’d need to go to her house, and that would raise a few questions. But maybe she’d be reasonable?
Then there was Home, where she was going anyway. There was the possibility of returning to normal the next day, and that offered a great possibility of getting them back without raising too much suspicion.
Or perhaps, she could go after Brittany instead? As she was, she’d be unrecognisable, the perfect chance to settle accounts with that Bitch!
The last option Mary considered were the forests, about an hour’s drive away and an another hour’s drive to be sure she'd get in deep enough. And have herself a fun time there away from prying/hostile eyes.
Her car back in Drive and the Handbrake Off, Mary pressed a bare foot down on the Gas and…
