"Can someone perhaps explain this to me?" Nicky pleaded.

"What needs explaining?" Cecilia Ironborn, a bunnygirl milf and Ariel Ironborn's fraternal twin sister. Despite having inherited her mother's status as a bunnygirl, she'd inherited a lot of her father's other features, such as long black hair that kinked and coiled, and warm brown skin evocative of the sky in autumn at just the right moment of dusk.

"Why does Ariel Ironborn, a human woman, have multiple monstergirl sisters?" Nicky asked.

"Because our dad fucked some monstergirls, duh," Cecilia said with a shrug. Then she grinned. "Heh. I'm fuckin' with ya- the story's been written down a few times, but I don't blame you for not having read it, if you wanna hear the whole thing. So, our dad's a human beta, and when she was growing up, she was real shy and awkward. Real interested in monsters, not so great with people. Y'know how it is. Well, she joined the Guild and became a well-known and well-respected delver, because she was real interested in monsters, studied 'em carefully, and knew how they thought, how they acted... and how to most efficiently kill them in a Dungeon."

"Alright," Nicky said, cautiously.

"When Dad hit Level 5, got her first Familiar slot, she immediately went and filled it," Cecilia said. "Her first familiar was a bunnygirl beta exemplar, and instead of the usual Familiar loadout of a gathering class and a crafting class... Dad gave her a crafting class and a combat class. Dad still wasn't great with people, see, and had been taken for a ride a few times before. Familiars, though, they're guaranteed to be able to work with you long-term. Sure, a delve partner who's always two levels below you isn't as good as a delve partner who isn't, but a delve partner who's an untrustworthy asshole is worse than no delve partner at all. So Dad kept delving. At Level 10, she took a cowgirl as her second familiar, gave her another combat-and-crafting loadout, and now had, just with herself and her familiars, a delve party that was capable enough to delve on-level, no outside help required. And then, when Dad was Level 14... there was an argument."

"Oh?" Roxy asked.

"See, Dad had managed, at Level 14, to snag a Familiar Slot Unlock," Cecilia said. "Those only give you the next Familiar slot early, so whenever she'd hit Level 15, she wouldn't get the third Familiar slot- she already had it, after all."

"Those exist?" Volex asked, quietly, and was promptly ignored.

"Shortly thereafter, while discussing what sort of monstergirl to pick as the third and final Familiar, they opened a chest that contained a dragongirl, and the matter was settled. But then, came the argument. You see... Dad's Familiars loved her, but they did not love delving, and after having been on the grind from 14 to 15 for ten years now, didn't like the thought of doing another twenty years of it, especially since they felt they'd already accomplished the major goal- getting that third Familiar. Well, Dad loved delving, but she loved her Familiars more, and accepted that they didn't want to delve with her anymore, and would rather settle down and make a new life."

"Wait, dragongirls are real?" Akane asked. "I thought they were just legends."

"Oh, they are very real," Cecilia said, nodding. "Anyhow, once they settled down, Dad was lost, 'cause here she was, 31 years old, having delved just about every goddamn day since she was 18, and now... now she'd have to do it alone, without her Familiars, and she wasn't sure she could stand that. And that's when Dad's first Familiar, that bunnygirl I was talking about, made a suggestion: start a family."

"Your mother was your father's Familiar?" Nicky asked, scandalized.

"Oh, like I didn't suck Roxy's dick the minute she bonded me," Lisa said. "Familiars can still say no to their bondmates, you know. Their personalities just generate so that they usually won't have to."

"Exactly," Cecilia said, nodding. "Yeah, Mom didn't have to have Dad's kids. She did it anyway because she wanted to. Again, it was her own goddamn idea, and the other Familiars warmed up to the idea not too long after Ariel and I were born. Clara came... oh, I think three years after us? And then Anzerath was born a year after that. And when we were coming of age, and were talking about becoming delvers in the Guild, Dad sat us down and said that, being monstergirls, we'd probably face some prejudice in the Guild. She said that she'd be in our corner no matter what, and that anything we needed, she'd help us get, and then said that one of the things she'd be giving us first was a way out. An alternate career path, if it turned out we couldn't stand being in the Guild."

"Lemme guess," Roxy said. "She gave you all some Rancher Class Unlocks."

"In point of fact, she gave us all a lot of non-combat Rancher Class Unlocks," Cecilia said. "Farmer, Miner, Blacksmith, Mystic Artificer, Alchemist, Merchant... you name it. It just so happens that all of us monstergirl daughters of hers picked Rancher, and started ranching monstergirls of our same kind. Dad thinks it's funny, and a little endearing; her kids are all interested in monsters too, after all. Just... not the same kind as her. Anyhow!" Cecilia clapped her hands. "You, Roxanne Updyke, favored student of my sister and currently highest-leveled living Dungeon Master. You came to me for help getting a Ranch started."

"Precisely," Roxy said, nodding.

"Then you have come to the right goddamn place," Cecilia said. "Clara might ranch cowgirls and breed them towards producing more milk and cum, but I ranch bunnygirls, and breed them towards producing more bunnygirls."

"Huh," Akane said. "What... is the benefit of producing more bunnygirls?"

"Ranchers can magically turn raw monstergirl byproducts into more processed monstergirl byproducts," Roxy said. "Monstergirls are, themselves, a raw monstergirl byproduct, and they can be magically turned into leather or fur. This is an expensive proposition, because it costs one monstergirl, but bunnygirls naturally have the Breeding Trait, which makes them well-favored by Ranchers looking to optimize for that kind of resource."

"...Oh no," Akane said.

"Yeaaah, Ranching ain't always clean," Cecilia said. "Sometimes, you gotta cull the herds. And sometimes, when you're in a field like mine? You gotta do it a lot more often. It helps to bear in mind that, as much as those bunnygirls look like people, they aren't. None of them can talk, or read, and that's not because people haven't tried to teach them. Pretty much the only thing anyone's ever managed is teaching them to know their name and come when it's called, and a few basic tricks." Cecilia shook her head. "Bunnygirls are cute, no doubt, but unless they're Familiars or just regular ol' sapient monstergirls, they are as stupid and simple as actual rabbits."

"If it makes you feel better, Akane," Roxy said. "I'm in the Rancher business for more sustained production- milk, cum, and eggs. Y'know, the stuff that's useful for an Alchemist. Buuuuut, that doesn't mean I'm not interested in having some breeding stock with, well, the Breeding Trait. Which brings us to business."

"Actually, what does the Breeding Trait do?" Nicky asked.

"It's simple, really," Cecilia said. "It means that the monstergirl has more children at a time. The details get a touch complicated, but if you didn't slack off during math class, it shouldn't be that difficult."

"Oh?" Akane asked.

"See, when two monstergirls breed, you add up their levels in the Breeding Trait. Wild bunnygirls have Breeding 1, so two of them breeding makes for a total of two Breeding levels. And the number of children in a litter is equal to two to the power of that total. If nobody has the Breeding trait, it's one offspring. If both have it at 1, it's four offspring. Ariel and I were twins because Mom had Breeding 1, and Dad didn't have any Breeding."

"And what level of Breeding have you achieved in your own stock of bunnygirls?" Roxy asked.

"Three," Cecilia said.

Nicky immediately started counting on her fingers, while Akane's mouth moved silently.

"Sixty four offspring per litter?!" they both blurted out at the same time.

"Impressive," Roxy said, nodding. "How'd you do it?"

"Natural mutations," Cecilia said. "Very rare on a per-monstergirl basis, but I've got a lot of monstergirls who're always making new ones. I don't need to rely on those potions Clara uses."

"How much do you want for sixteen of them, unrelated enough to constitute a breeding population?"

"Money's still in flux right now, so it's basically worthless at our level. We'll need to do a trade. So, what've you got?"

"Barrels upon barrels of Level 13 potions, for one."

"Eh." Cecilia shrugged. "What else?"

"Well, I did a Level 13 delve to get Rancher to that level, plus I'm a Level 13 Mystic Artificer. I can make some Rancher-specific enchanted items, to your specifications."

"I'm also a Mystic Artificer," Cecilia said. "What I'm not is a Farmer. How much food do you have?"

"Food?" Akane asked. "I thought Ranchers sustained monstergirls with their class."

"Yeah, but there's limits," Cecilia said. "If you supplement that with food, those limits are bigger. Monstergirls eating a full diet like a human straight up don't count towards the limit. So..."

"Right, right," Roxy said, nodding. "Alright, so, in recent times, delvers turned Farmer have started measuring food in koku."

"Ooooh, I recognize those!" Akane said. "That's a unit from my mom's homeland! That's how much food it takes to feed a person for a year, right?"

"Well, traditionally it was a measure of how much rice it takes to feed a person for a year, with the understanding that this rice would be supplemented with other foods, even if it made up the bulk of the diet," Roxy said. "But, yes, these days, the koku is in fact defined such as to represent one person-year worth of food, so as to make for easier computations of how much of each food crop one needs in a balanced, healthy diet. Recently, there was a study done by a huge group of delvers to test out one proposed diet for two years, while they're still delving, and the results show that twenty whole koku of a certain spread of farmable crops results in a healthy, sustainable diet even for full-time delvers, who typically consume two koku of food a year."

"And are you capable of producing those crops?" Cecilia asked.

"Those were some of the first seeds I'd collected when I was a Farmer," Roxy said.

"Great," Cecilia said, nodding. "I want a thousand koku of that blend in exchange for the bunnies you want."

Nicky choked on her own spit and started coughing.

"Twelve hundred, and you'll suck my dick, too," Roxy said.

"Your bartering technique is fascinating," Akane said.

"Nine hundred, and you fuck me hard enough to make me cum," Cecilia said.

"Eight hundred, and I'll make you cum three times," Roxy said.

"Deal," Cecilia said, sticking out her hand.

They shook on it, and then started kissing.

"Really?" Nicky asked. "Right here?"

"Go, Roxy, go!" Volex cheered.

"Put some bunnies in this breeder!" Lisa added.

"Just so you know," Cecilia said, pulling back from the kiss. "I'm on birth control, because I don't want to have kids, and if you do anything that'd circumvent or counteract that, you will be on the hook for raising them."

"Duly noted," Roxy said, nodding. "I'm on birth control myself, because while the idea of knocking people up is hot, the actual realities of a person being pregnant and then having to raise children is... less so."

"Glad we're on the same page," Cecilia said, before resuming the kiss.

Roxy picked up the bunnygirl by the hips and stepped forward, pressing Cecilia's back against the wall, before hiking up the bunny's knee-length skirt and pulling down her own pants.

Cecilia, like all of the Ironborns, was a beta, but unlike her unlucky little sister, she was a beta exemplar, much like Volex and Lucy. Her cock was bigger than Roxy's, and her tits gave Akane's a run for their money. But her pussy was just as soft as anyone's, and Roxy groaned quietly in pleasure as she slid herself in.

Cecilia's lower body was powerfully-muscled, not just from being a bunnygirl, but from having been a Spellblade as a delver, reliant on speed and positioning to be most effective. Those same hips and legs which propelled her through the ten thousand delves she'd embarked upon with her sisters and father to reach Level 15 were now wrapping around Roxy and milking her cock for every drop of pleasure it could provide, riding it to the promised land of three climaxes.

Roxy silently deactivated the enchantment that'd make Cecilia temporarily count as a Succubus; she'd notice if it was still active when Roxy came, and have questions that Roxy didn't need. Besides. After all those delves in Sex Dungeons, Roxy had picked up plenty of slightly more normal items, spells, techniques, and actual experience that added up to a sexual powerhouse.

Cecilia's own hands came up, grabbing the hem of her tank top, and pulled it up, letting her not-so-little bouncy bunnies out to play, where Roxy immediately latched onto them with her own hands, kneading the thick, juicy breasts like over-hydrated bread dough that needed to be worked for a long time before the cohesive strength of the gluten overcame the sheer stickiness of the wet flour. And like two balls of over-hydrated bread dough, Roxy's hands stayed in full contact with them at all moments, never coming away for even an instant.

Cecilia's breathing was starting to come more quickly and more heavily, and Roxy broke the kiss, pulling herself and Cecilia's hips back away from the wall, letting Cecilia's upper body lean back at more of an incline. For most, this would've been uncomfortable, but the sheer bodily capacity of a Level 15 anything, let alone a bunnygirl Spellblade, meant that Cecilia could comfortably hang solely from Roxy's hips by her legs, with her head an inch off the ground for hours at a time if she needed. This was nothing to her.

To Roxy, it was a cleaning measure. As Cecilia hit her first climax, that fat cock of hers deposited those thick loads of hers onto her belly and chest- Roxy finally let go of Cecilia's tits- without getting any on Roxy's clothes. Her second and third climaxes, not too far behind, went the same way.

Her obligations fulfilled, Roxy pulled herself out of Cecilia, and finished herself off, painting the bunny's tits with more cum.

"Mmmmn... pleasure doing business."
