Mark woke up to the feeling of someone sitting down on the bed next to him. For a moment, he was surprised that he had been sleeping in the first place, but then he remembered Tanya dozing off with him. He remembered the warmth of her body, and the comfortable numbness that had overcome him after he had left a load of his sperm in her pregnant pussy.
He looked up. It was Tanya who had sat down next to him, alright, and she was sipping from a canned drink -- a protein shake, it seemed.
"Hi," Tanya said as she noticed he was awake, gently running her fingers through his locks. "Back among the living?"
"Mmmh," Mark replied, stretched and slowly sat up. "How long have I been sleeping?"
Tanya shrugged. "Only a few hours, I suppose," she said. "I haven't looked at the time, but it can't be later than three or four in the afternoon."
"Good."
Mark stood up, looked around, picked up his underpants from the floor and slipped into them.
"Aw," said Tanya, pouting.
Mark grinned. "What, you want another round already?"
"That too," Tanya replied, "but I also liked the view until now. You have a really great butt, you know that?"
"Thanks. Yours is amazing too. And I'm now qualified to offer an expert opinion on that."
Tanya giggled. "It's a lot bigger now that I'm pregnant. Are you into big butts?"
"I'm definitely into your butt," Mark smiled, "no matter whether it's small and tight or big and soft. Though..."
"Though?" Tanya raised an eyebrow.
Mark sighed. "I still can't believe how fast pregnancies go for you," he said. "It's so unreal. You're telling me it's nothing but biology at work, but if it really is..."
"Yes?"
"Then why haven't I ever heard about it before?"
Tanya smiled, and it was one of her wicked little smiles again. "That's because we're doing our best to keep it secret."
"We?" Now it was Mark's turn to raise an eyebrow. "Are you saying there's more than one of you?"
"Heh." Tanya's smile got even wider. "There's a whole lot of us. And there's more of us every day."
"Then -- who's 'us'?"
"Women like me," Tanya explained. "Women whose biology works faster than normal."
Mark looked at her in disbelief. "And where did you come from?" he asked. "I mean, have you all evolved at the same time, or what?"
Tanya had to laugh again. "No, Mark, we were born this way. Born from women who already had the same biology. We inherit it from our mothers."
"Oh. Then..." Mark looked at Tanya's belly. "Then our child...?"
"Will be just the same," Tanya nodded. "All my daughters share this ability, and ours will be no different. It's an evolutionary advantage, remember? Of course she'll inherit it."
That revelation was enough to make Mark have to sit down again. "Wow," he said, "I wouldn't have thought it was like- like this. I mean, wow, you're able to give birth to theoretically hundreds of girls during your lifetime, and if each of them is able to give birth to the same number, then your granddaughters alone would number in the tens of thousands, and the generations after that..."
"That's the whole point," Tanya smiled.
"Huh?" Mark looked at her with a puzzled expression on his face. "The whole point of what?"
"The whole point of..."
That moment, the bedroom door opened, and a brunette, tall woman wearing a very expensive-looking skirt suit entered the room. Her expression when she saw Mark was one of utter disbelief.
"What the FUCK, Tanya?"
Tanya ducked and smiled at the woman in an apologetic way. "Hi, sis," she said.

"This is the dumbest thing you've ever done! I mean, you've done a lot of dumb things, but really, now you've surpassed yourself, Tanya. This is absolutely un-fucking-believably, mind-numbingly stupid!"
"Look, Stephanie," Tanya tried to explain, "it's not like you think it is."
"It isn't?" Stephanie threw her hands in the air, looking as though as she was about to scream in frustration. "Then, please, tell me, by all means: What in Mother Earth's name were you THINKING when you brought one of your fuck-toys here?"
"Hey!" Mark couldn't help feeling that Stephanie's anger was probably not unfounded, but that should have been no reason to insult him. "Don't call me a..."
"I didn't bring him here," Tanya defended herself. "He found this place on his own."
"Exactly," Mark said. "And I'm not her..."
Stephanie ignored him. "Yeah, right," she hissed, "how very probable. And I suppose it's also a coincidence that the two of you smell of sex, isn't it?"
"No, that's not a coincidence," Tanya said, "that's because we DID have sex."
"Ah hah!"
"But I didn't invite him here, and I didn't tell him how to find this place either."
Stephanie crossed her arms. "Impossible," she said. "How else would he have known?"
"I'm not sure myself," Tanya explained, "but it's probably because he sucked my tits."
"He what?"
"Sucked my tits, or at least one of them." Tanya leaned back a little. "Yeah, I know, I was probably a little careless, but how could I have known that this was enough to..."
"Regardless, once he was here, of course you HAD to sleep with him," Stephanie continued chastising her. "Dammit, Tanya, we have this rule for a reason! No strangers inside the safehouse!"
Mark was slowly getting angry too, mostly at being ignored. "I'm not a stranger", he insisted. "I'm the father of Tanya's child."
That seemed to have gotten Stephanie's attention. "Oh, so you are?" she said. "Brilliant! So I suppose she even told you that her body works in mysterious ways, didn't she?"
