"Doctor Wolffenstep!" Cuddles complained, "Just handing out candy is no fun!"
The illustrious mad scientist and dark sorcerer sympathized with his pet and occasional familiar, who currently wore a mostly human form thanks to the successful test run of his Enanthropomorphosizer Mark III earlier in the day. Nonetheless, he had to stay firm. He gave her a scolding frown, or at least as close to it as he could manage while she was giving him a lovingly enthusiastic cock sucking. They were waiting in the library, adjacent to the foyer for the next batch of trick-or-treaters,. His initial plan had been to study the test readings on the Enanthropomorphosizer while she handed out candy, but Cuddles, always randy whenever he gave her human form, found a more pleasant way to pass the time between visitors.
He cleared his throat and tried to be stern. "Now, young lady... er, kitty... you need to remember that for the last hundred years we of the monstrous, mystical and otherworldly persuasions have abided by the Salem Convention, which clearly states in Article Three that we will allow the young mortals to enjoy their Halloween festivities in peace."
He couldn't help but admire his handiwork. Perhaps he needed to add a reasonability circuit into the machine, since her 30G-cup bosom seemed a tad overboard, and despite long since achieving feline adulthood she looked barely sixteen, but this was mad science after all, so he generally tried to leave reasonability out of the mix. At least this time she came out almost completely human. The only failures were the cat ears, tail and somewhat pointy teeth. The teeth had their drawbacks, he was discovering, but she only nipped occasionally as her supple lips glided with sensuous skill over his hardness.
The perimeter alarm went off again, indicating another group headed up the walk.
"But it's not like I want to harm any of them!" she sulked after she slipped off his cock and grabbed the candy bowl. "I just want to play with them!"
He picked up a sheaf of readouts to cover himself if a wayward child got inside. "Most of our visitors tonight are far under age for the sort of play you have in mind. I guess you don't have a sense for that with humans. Try to think of them as kittens only a few months old."
"I know that! I'm talking about the big ones!" she insisted, having stopped to argue, but at that moment the chimes resounded through the halls of Wolffenstep Manor. She scampered to the door to take care of them. A second crowd apparently delayed her retreat, but she finally made it back to resume her eager suckling. Her desire for sex with others didn't diminish at all her passion for her master. Whether he used a black magic spell or his latest convert-beast-to-human invention on her, his loving pet always eagerly made love to him when human. She simply wished to have sex with just about every desirable human she encountered as well.
He always assured her he was seeking a way to permanently change her to human, her longtime desire, but even he worried about setting her loose on the world. He was usually able to put that concern aside though. No proper mad scientist balks at the negative effects of his inventions.
After he leaned back and enjoyed caressing her a bit, he lectured, "The big ones, as you call them, are responsible for the safety of the little ones, so you mustn't sidetrack them. This night belongs to the children, dear. Just hand out their treats like a good kitty."
"Where's
my
treat?" she whined, switching to her hands so speaking didn't interrupt her play. "I'm doing all this work!"
He looked at her in speculation, and decided to let himself be persuaded a little. He always had been a sucker for a pretty face, even one of his own creation. "Hm. Well, pick one out. Just one, above legal age. The convention doesn't restrict us from the adults, after all. Don't do anything; just tell me. I'll make the arrangements."
She brightened up after that. In fact, once she finally swallowed his load many interrupted lovings later, she hovered at the door, watching with excitement for a good candidate to come along. Unfortunately for her, it was one dumpy housewife or beer-gutted dad after another for quite a while. Eventually though, he heard her hiss, "Doctor! The next group! This is the one!"
He observed on the monitor. The chimes rang out again, and Cuddles threw open the door to a chorus of "Trick or Treat!" at various dissonant pitches. A wolf man, a vampire, an Obama and two princesses, all under four feet tall, stood in front of a slightly harried looking teenage girl in a witch's hat. The doctor shook his head. The prospect stood a serious chance of being underage, which his cat wouldn't have the human sense to know. However, he went ahead and began the Identification spell. He'd mostly given up on sorcery, having switched to mad science many years ago, but once in a while that old black magic came in handy.
Cuddles certainly had good taste. Her choice possessed a far more slender figure than her own, with just barely enough curvature to avoid the description 'willowy', but her face was comely with bright green eyes and a delicate nose, and her lovely blond hair cascaded down to the middle of her back. Probably a bit over five and a half feet tall, he guessed. She had a future as a model if she so wished.
"Nyaa!! What a scaaaryy bunch you are!" Cuddles oozed to the children as she handed out their treats. They seemed delighted with her 'costume', a black minidress to match her black hair, tail and ears. The teenager gave her a smirking nod with arched eyebrows. "Not bad at all. They look real!"
"Thank you! Bye-Bye! Nyaa!" Cuddles called out with a wave as they departed, then shut the door and scampered back into the library with excitement in her eyes. "Well, Doctor?"
He held up the one-fingered signal to wait, almost certain he would be disappointing her. The spell whispered its results to him a few seconds later.
Samantha Reed. Eighteen years, one month, two weeks, three days old. 1724 Curtis Court.
With relief he beamed at her. "You're in luck, Cuddles. She's just barely old enough. I have to wait for her to bring her young charges home first, then we shall summon her here."
Cuddles bounced up and down clapping her hands. The pleasant effect this had on his libido brought another issue to mind.
"Hm. I may have to come up with something for me, as well," he mused. "I'll hardly be unaffected by the goings-on, after all."
