Henry and Jessica Black had a secret.
Or rather, their families had a secret. One they had been keeping secret from their daughter, at least. For Henry came from a prominent family of vampire hunters, while Jessica, a family of werewolf hunters.
They had tried to keep their daughter out of their family legacy. They had broken away from the family, and each given up a large inheritance, to try to live a normal domestic life together. But that morning, they had been urgently contacted by the main families, and given a warning that a powerful vampire, and a powerful werewolf, had formed an alliance and were in their little town, and gathering forces. They didn't want to be involved, but they were the only ones in a position to catch them in time, and the family business ran thick in their blood, and it was never truly something they could get away from.
Trying to shield their innocent daughter from the perils of dangerous supernatural elements, they told her that they were off to check out an antique shop. It wasn't entirely a lie. After all, the vampires and werewolves were hiding their operation under the guise of an antique shop.
"Dmitri, it had to be you," Henry said.
"My old nemesis. Emphasis on old, Mr. Black. Wouldn't it be better if you just gave up and joined us?"
"I'm only 45," Henry said.
"And you look every day of that. When last I saw you, you were in your twenties. It almost saddens me to see you like this, if I wasn't about to suck you dry and turn you into a ghoul, of course.
"Fat chance, Dmitri," Henry answered, as his wife stood back. She knew what was coming, and that the best thing for her to do was to keep her distance.
Henry leapt at Dmitri and threw a punch that seemed to be in slow motion, yet it somehow hit Dmitri. Dmitri spun around and a crater appeared in the wall behind him, rocks flying. Dmitri threw a blow that missed as he slid past into a bookshelf. The bookshelf flew apart, the individual books shredded to pieces, before Dmitri turned around and rolled into a ball in midair and nearly ended his descent in a headbutt against Henry's face, except Henry blocked it with his crossed forearms. Dmitri hissed like a cat, for even making any sort of cross against a vampire was a blow to their astral selves.
"Oh, your reflexes still aren't bad," Dmitri remarked. "I see this old fool still has fangs of his own."
Back and forth their fight went, every move seemingly slow, each one missing the other with every blow, yet causing immense damage to everything around them. Dmitri did some sort of fancy kick which missed, but its momentum took him right through a wall, then he did a backflip back into the room with a kick that Henry narrowly dodged.
Meanwhile, newly converted werewolves had just started swarming into the room. Now was Jessica's turn to show her specialty. She took out two shiny silver pistols and started firing rapidly. She hit some of them, causing them to disintegrate into dust, and then she rapidly reloaded.
"Retreat!" Dmitri called out. The surviving werewolves fled from the room.
"I'll get you one day," Dmitri said ominously, behind his cape which he was holding out. "After all, I'll only get stronger, and father time will only take more and more away from you." He vanished into a swarm of bees, which scattered.
Disappointed in their mere semi-success, Henry and Jessica returned home.
"If only our daughter knew the truth about us," Jessica commented to Henry.
"What would be the point of that? Our little Karyn is soft, and helpless. If she was flung into our world, the werewolves and vampires would tear her to shreds on the first day."
He opened the door, to see... what were they? They weren't werewolves, they certainly weren't vampires, they were like nothing they had ever seen before. But one of them was definitely their Karyn. Her face was unchanged, after all. They had seen supernatural beings enough, that they could see on glance the difference between them and cosplayers. This wasn't just Karyn in a costume. They both knew that.
"Hi mom, dad," Karyn said. "We have a surprise for you."
"Karyn?" Jessica said in disbelief. She wanted to ask what the hell happened, but was afraid of saying anything. Especially when strange furry things appeared in her... four... paws? Just appeared, out of nowhere.
"Jon, could you help me in, convincing my parents to join our cause?" Karyn said to the other one.
"Jon?" Henry asked. Karyn's friend? This, strange exotically beautiful but dangerous looking and clearly female creature was Jon? Strange furry things appeared in her four front paws as well, before she said "Well this isn't awkward at all." They at least seemed to have their personalities intact. But what were they? Some weird new mutation of werewolf?
Henry and Jessica didn't have long to ponder this though, as they both drifted off into a daze and lost track of what was going on around them.
As they were in a trance, Henry and Jessica heard voices, and had strange dreams, and then suddenly they woke up. They were in their living room, and the transformed Jon and Karyn were not there to be seen.
"Nya!" Jessica cried out. She looked down at herself, and pawed at her four big breasts, with her four big paws. "What, what happened to me? Who are you?"
"I'm Henry," Henry said, in a high girl's voice. "Eep!" she said, noticing her own breasts. And what's more, she had four of them as well.
"Henry? Is that, really you?"
"Meowwwww," Henry said, holding up her four arms, looking at the pawpad sides of her new kitty paws. "I'm, not sure, I'm me any more. I think, I'm a girl. Oh honey, what has our daughter gotten into?" Henry was now afraid both that this was the end of her marriage, and concern over the nature of the new species her whole immediate family apparently had now been transformed into.
"I don't know," Jessica said, her eyes narrowing on her husband, her long tail swishing in the air behind her. "But just so you know, you look like you're about 20 again, or how you might have looked if you'd been a girl, and I think I can make this work for me," she said, as she delivered a pounce on her husband. They shared a kiss, and rolled around on the floor, pawing at each other, unable to contain their libidos.
"He he, maybe this isn't so bad," Henry said, as she pawed at her equally young-looking wife, their tails twisting together. "I think I feel, pretty strong, like this too. Maybe, this could even help us with the vampires and werewolves. Meow!" she cried out, as Jessica had pulled down Henry's pants and was invading a part Henry wasn't supposed to have with her tongue, while her four front paws had wandered up to deeply knead into her husband's breasts as she purred. Ok, maybe it's not the end of our marriage, Henry thought to herself as she purred back and scritched her wife's kitty ears and massaged her shoulders with her many paws.
Jon watching this almost out of view through the window to the outside, backed out of view, to give Karyn's parents their privacy.
"Yeah, they're awake, and I think they're fine with it. Just, don't go in there, Karyn. Trust me on that."
"Oh," Karyn said, taking the hint. "Well, onward we go," she said.
"You know, Karyn, we can't convert the whole human species one at a time like this. We're going to have to either make it into a disease that spreads, or something that compels people to chase after and convert others, or something to make it grow exponentially."
"Yeah I know," Karyn admitted.
"Karyn. I can't help but notice, the particulars of what we did to your parents, under your direction, and, um, would you," Jon started, looking down at her own natural two breasts, "be more attracted to me, if I had bigger breasts, or, you know, more than two of them?"
"No comment."
"What?"
"I find you plenty attractive as you are, and I don't want to pressure you into something."
Jon opened her mouth, considering saying something more, but decided that was such a charming sentiment and that she didn't want to ruin it.
"But actually, I was also thinking we'd save those slots for more powers," Karyn continued.
"More powers?"
"Yeah. You don't want to have to remove your paws and redo them with 5 different powers, everything we've already established, the power to pull new parts out of nowhere, hypnosis, whatever else, all at the same time every time we want to add a new attribute, right? What if we messed it up, it's hard to get all that straight. Like say you want to make the condition contagious, and maybe another power, and another, teleportation, invincibility maybe. You could just put those powers into new boobs and add them."
"Oh. That's an idea."
