Rosalanders

Bellis walked down the corridors of Rosalind's new laboratory. Once it had been her residence when she was but one of the Elders. The building was apparently devoid of life, save for the occasional assistant skittering down the hall, only pausing long enough to give Bellis a polite little bow before resuming their pace. The ornately shaped wood and been bored into, removed, or completely destroyed. Thick magitech cables emerged from one hole, crisscrossed along the floor, then disappeared into another. The air smelled of fel magic and ozone.

She managed to make her way to her old study without tripping. Inside, Rosalind was applying some kind of salve to a giant pitcher plant.

"Ah, Leader! Glad you could make it. I have the answer!" She put down the salve and stepped over to a large curtained area. Bellis remarked that this was the exact same dramatic reveal curtain from her old lab, just stretched over a larger area.

"Please, Rosalind. No theatrics. I have an empire to run."

"Ah. Yes. Okay, quick recap. We have male slaves, which we like because they have cum, which we like even more. But we also have female slaves, which, although fun on occasion, are pretty useless for our myopic sex-slavery purposes. So, ultimately, we need a way to make females useful to floran society. Presenting: Rosalanders!"

She pulled back the curtain, revealing a human not unlike others Bellis had seen. She was rather voluptuous. Full-figured would be the best way to describe her. Thick hips, curves, and a huge pair of tits. Florans tended to be on the small side, so her bust left Bellis a little awed. The only thing different about this female was her nipples. They were green.

"She looks pretty human to me."

"On the surface, yes...But watch this." Rosalind gripped the woman's breast tightly. The woman moaned, more in more pleasure than pain, and a bead of white liquid dripped out her verdant tip.

"Lactation? That's not new. Mammals can't stop lactating."

Rosalind smirked. "It's not milk. It's cum."

That caught Bellis' attention. She stepped over, slid her finger across the fluid, and tasted it.

"Holy Earthmother..."

"I know, right? I've spliced her mammaries with genes from the testicles of a centaur. She'll produce manmilk now, most of the time anyways. They start out with human-level intelligence. Maybe a little more naturally subservient, but otherwise baseline. But as cum builds up in their tits, a hormone variant triggers in their brains. They get more docile, more submissive, and very, very horny. They'll present to anyone, begging them to stick it inside their holes. And all the cum that's poured into them, either in their mouths or their pussies or their butts, it all flows into their breasts. They become desperate to get milked. When they do get pumped, it's intensely pleasurable for them. This one came three times before I drained her dry. Didn't you girl?"

The human hummed. "Yes Mistress Rosalind...I love being your cumcow."

"Cumcow?" Bellis raised her eyebrow.

Rosalind blushed. "Just a working name. I'm going with Rosalanders, officially. So I've solved the female slave crisis, and made a mobile cum reservoir. And I'm basically a god."

"Can they reproduce?"

Rosalind frowned at her magnificence not being appreciated. But she sighed, and continued the exposition. "Yes, but only rarely. Since she naturally sucks up cum into her tits before it gets a chance to find the egg, it'd take a lot of jizz to impregnate her. If by some miracle geyser of semen she gets pregnant, she'll revert to making milk again."

"And these...Rosalanders. They used to be fully human?"

"Yes. This one was pulled from one of our snatch and grab operations in the north. I've miniaturized and automated the chemical process used in my Gene Twister, and placed it in the body of a pitcher plant. I call it the Venus Pod." The scientist stepped over to the large plant still looming high above them in the room. "Just slip in one of the human female captives, wait about six hours, and out comes a docile, productive servant. They'll have their old thoughts and memories, but their old lives won't seem to matter. All they'll want is to be milked and to obey. It's designed for humans, but it will work with most mammalian humanoid species. Not florans, though. Just common sense. Needed to prevent a kind of cautionary tale, hoisted on your own petard scenario." When she got a confused look from Bellis, she coughed awkwardly.

"A whole other race of only women...interesting."

"Well, funny you should say that..." She pulled the curtain a little farther, revealing a second person. This one was male, also naked. His cock matched the green of the cumcow's nipples, the shaft erect and pulsing with need. "I made a male model as well."

"Of course you did." Bellis examined the nude man, finding his rippling muscles and controlled desire to be utterly attractive. She traced her finger down his naked chest, stopping at the base of his firm length. He let out a tiny whimper as she pulled her hand away. "I don't exactly disapprove, Rosalind. Not at all."

"I'm glad you like him. Same rules apply. Their whole lower torso is basically just one giant semen factory. And as it builds up, it gets harder and harder for them to think. They get painfully erect, their minds full of every possible sexual scenario they can imagine. They can masturbate, but they can't cum unless someone else makes them. They'll beg, they'll scheme, they'll to anything to release their thick cum and get their minds back. At least for a while."

"Mistress." The man with the green dick said in a strained tone. "Stud needs...I need to cum."

"Well don't look at me, stud. I'm not helping you." She pointed at the female Rosalander. "You. Cumcow. Make him fill your mouth."

The human hybrid practically leapt to the floor in front of him and started sucking. Either he had gone too long without sex, or she was too experienced at giving head, but it took only a minute for him to climax. He grunted like an animal, thrusting deep inside her mouth as he came. The cumcow dutifully gulped down his seed, her breasts expanding just a little bit.

"This is...this will do." Bellis said, giving Rosalind a firm nod. "I want our human female population cycled through these Venus Pods as soon as possible. Leave the male transformation as a punishment for the disobedient. Obey the rules, or you'll be put to stud."

"Can do! Soon there'll be a whole new race of humans on the map. Can you two believe that?" Rosalind turned to the Rosalanders, but they were too busy fucking each other to notice history being made.
