Marie entered her office. To her puzzlement, the lights were off and the windows were opaque. That was odd. Shouldn't they have gone on automatically?
She tapped the light switch but it had no effect. Mildly annoyed, she started glowing on her own - giant of light, after all - and prepared to tell her secretary to call maintenance-
There was another Ultrawoman in the room, who hissed and shrieked as Marie's glow illuminated her. "Aha! You have fallen right into my trap, Mother of Ultra!"
Marie blinked. "Huh?"
The darker gray Ultra with blood-red vein-shaped markings, black bat wing horns, bat wing-shaped armor over her chest which accentuated her sizable chest and framed her red Color Timer, cackled malevolently in a Space Slavic (Splavic?) accent, revealing fangs as her red eyes gleamed sensually and her cape swished behind her. "You didn't even notice that I've already mesmerized your staff to serve me!"
Confused, Marie glanced outside and saw no noticeable difference in her secretary. "You did? She usually looks like that because she spends her time on social media when she should be working."
"O-oh," the other Ultrawoman murmured, surprised. "Well...it matters little, for you have walked right into my clutches! I am Ultrawoman Carmilla - not to be confused with Carmeara or Camearra-"
"Right, it is easy to mix them up, especially since they're alternate universe versions of each other. Or...Parallel Isotopes?" Marie wondered.
"Regardless! I am Carmilla, Mistress of Darkness! I have drained the light from countless worlds and turned them into my beautiful slaves, and you shall be my next one!" Carmilla paused, looking Marie up and down. "I was already planning for you to be the crown jewel of my harem, but...wow, pictures don't do you justice, you're REALLY beautiful."
"Thanks? Also, if you want me to be your slave you'll have to get in line, Hegemon Kyukogo's already trying to stake a claim," Marie said.
"Oh, I shall come for her and her Hegemony soon enough!" Carmilla cackled. "But first, I shall drain your light, and with your power added to mine, I shall be able to drain the Plasma Spark, extinguishing the Land of Light so darkness may reign-"
"That'll freeze the entire planet in seconds," Marie interrupted.
"I'll use my new power to create a dark sun and raise everyone as vampires, it'll be fine," Carmilla said dismissively.
"Oh, okay."
"Darkness will reign, and the light shall die forever! Now, let me drink your light!" Carmilla hissed, cape billowing behind her, cackling evilly as she thrust her bosom forwards, a beam of darkness lashing out from her Color Timer and latching onto Marie's. She continued laughing while undulating very sexily as Marie just stood there blankly.
However, after a few minutes, Carmilla trailed off. "Uh, wow, there's, there's a lot more light in you than I thought, it doesn't, it doesn't usually take this long."
"Do you need to take a break, or...?" Marie asked.
"No, no, I've got this," Carmilla insisted.
A few minutes later, she cried, "NO! How...how can one being have so much light?! It's...it's too much! The warmth, it's, it's too much! It's burning me up from inside!"
Marie, only feeling a teeny tiny bit weaker, asked, "Do you want me to have a look at you? This is a hospital and I'm the greatest doctor in the universe."
"Oh, I'd very much like for you to examine me," Carmilla said eagerly. "But no, this light, it's...oh! OHHHH!" she cried orgasmically. "The light...why...why does it shine so BRIIIIIIIGHT?!"
A tremendous shockwave and a spectacular blast of light rippled out from the vampiress, blowing back Marie's hair and mantle and shattering the office windows to let in the light of the Plasma Spark as part of some big symbolic triumph of light over darkness or something like that, she didn't know.
Carmilla, now with blue eyes and Timer, was kneeling on the floor, looking lost. "I...I live? Yes...I live...and the light..." She touched her chest. "It fills me with so much warmth...the void of darkness within me has been replaced by glorious light..."
She looked up at Marie tearfully. "I...I yield. Everything I have, everything I am, is now yours...my Mistress. I, and all my beautiful slaves, now belong to you forevermore."
She prostrated herself, forehead touching the ground, occasionally glancing up at Marie with a besotted look on her face.
Marie sighed.
"Hey, boss, did a bomb go off in here or something?" her secretary asked, poking her head in.
"Bete, do you feel an obligation to love and obey me for the rest of your days, and let me use you as a fucktoy if I asked?" Marie asked.
"No more than everyone else in the building, why?" Bete asked. She gasped. "Wait, am I going to-"
"Not today," Marie said, taking mild pleasure in watching her secretary's face fall. "Call maintenance to have them fix my office. And the lights."
"Yes Mistress Mommy!" Bete replied cheerfully.
Marie sighed again. Then she walked past the hopeful, whimpering Carmilla towards her desk and called her husband.
"Marie! Hi! How are you?" Ken asked pleasantly, as if he hadn't just seen her five minutes ago before they both used their magic doors to get to work.
"Ken, it happened again," Marie said wearily.
"An assassin or other ne'er-do-well assailed you, only to be smitten by your beauty and swear themselves into your service forevermore?" Ken asked.
"Yes."
"Splendid! Who was it this time?" Ken asked.
"Carmilla. Some kind of light-vampire," Marie said.
"Oh, Carmilla, we've gotten some reports on her," Ken murmured, checking his terminal. "Lost quite a few Ultras to her..."
"They all still live, but serve me - and now Mistress - loyally!" Carmilla shouted.
"Oh, well, that's all right then, I'll get Zoffy to change their status back to 'alive and bound to Mother of Ultra forever.' At this rate we're going to need a new form for all the Ultrawomen or other beings you manage to charm, he'll love writing one of those," Ken remarked. "Of course, I'll need to fill one out myself, ha-ha! Will you be bringing her home tonight?"
Carmilla gave Marie a pleading look. "Apparently," she grumbled.
"Wonderful, I'll be sure to let Jack know in advance, he's always been spooked by vampires after that thing with Draculas," Ken said. "Funnily enough, he was an Alien Carmilla!"
"No relation!" Carmilla shouted.
"I'll make sure to let him know that so he doesn't impale you on an Ultra Cross. Have a fun time breaking her in, Marie! Love you!" Ken said cheerfully.
"Love you too," Marie said as he hung up.
"He seems nice," Carmilla said.
"Yes, he is," Marie said with a fond sigh.
It was at that point Kyukogo called because of course he did.
"Hello, Mar-" Kyukogo started to say, only to pause when she saw Carmilla. Her face fell. "Oh, darn, there goes that idea. Sorry girls, she's already got one!"
"Awww!" the bevy of gorgeous alien vampires behind her whined.
Marie sighed.
