The story begins in the moment that the consciousness of Mizuki, a Japanese man of our era, is reincarnated (i.e. "isekaied") into a generic RPG-style fantasy world. Whoever he may have been before, and we have no way of knowing, Mizuki is now a scrawny, straw-haired adolescent equipped with only one game-type skill: "brothel expert". While the combat utility of his new skill proves limited when Mizuki stumbles upon the isekai genre's obligatory intro slime, an attractive young woman with cow-like ears and horns luckily arrives in time to rescue him. From this, we may conclude that world into which our protagonist has been reborn contains kemonomimi. A man of culture, he takes it in stride.
After dispatching the slime, Mizuki's bovine savior cheerfully introduces herself as Ururu. Ururu is, as one might expect, a Big Girl. Her thick hips and truly gigantic breasts stretch an otherwise modest dress to its limit, and though she appears to be only a few years older than Mizuki, perhaps in her late teens, she towers over him. By convenient coincidence, it seems she's on her way to a nearby city in hopes, for her family's sake, of finding work as a prostitute. Mizuki's new skill then comes in handy, allowing him to assess Ururu's innate A-rank prostitution aptitude at a glance. The cow was born to sell clover.
Since their abilities so closely align and he too will soon need a job, Mizuki accompanies his new friend to Animal Girl, the city's kemonomimi brothel. There, they meet the brothel's owner, a trim but well-stacked fox woman named Diena who appears to be in her late twenties or early thirties. Since the ability to do basic math is rare and therefore valuable in this world, Diena hires Mizuki on the spot. She has doubts, however, about Ururu. Animal Girl, she says, needs a prostitute who can take the oversized equipment of horse-type men. Though a cow woman would typically be ideal, Ururu's vagina proved too tight on examination even to admit Diena's small paw.
Thinking quickly, Mizuki "invents" both paizuri and intercrural sex.
He demonstrates the former by inserting his improbably large penis between Ururu's equally improbable breasts and requesting that she use them to help rub him to orgasm. The curious cow does her well-equipped best, inspiring Mizuki to release an impressive quantity of genetic material upon her chest. Both women seem intrigued by the novelty of the act, but while Diena samples Mizuki's seed with evident appreciation, she hasn't yet changed her mind about Ururu's suitability for employment. Hoping that a display of intercrural sex will prove more convincing, he asks Ururu to pull her underwear aside. From behind, Mizuki leans into the luxurious spread of his beautiful young girl friend's ass while slowly thrusting his penis in between her thighs. With each stroke, Diena can see it emerge beneath Ururu's slit, parting the soft folds of her labia to kiss the rising nub of her clit.
Aroused and fascinated, the fox crouches down in front of Ururu's crotch, masturbating as the cow gir's hips begin to roll in rhythmic sympathy with the surge of Mizuki's erection. Moaning sweet and guttural, Ururu grinds her fat ass against her handsome young boy friend's lower belly, tipping her vulva down against his thick and rigid heat. Each time the glossy head of his penis slides out from between her thighs, it drips and glistens with the tide. The cow's blushing sex, in fact, so overflows that fluid runs hot rivers down her legs. Breathing shallowly with two insistent fingers buried in her own furry foxhole, Diena just watches them fuck.
The action continues, moving faster, ever faster...then abruptly stops. A soft cry escapes Ururu's lips as, for an endless instant, every muscle in Mizuki's body clenches tight. Diena's eyes widen as, mere inches away, the tip of the boy's bulging glans erupts. Gouts of hot semen suddenly burst forth to splatter against her face, accompanied by the squirting gush of Ururu's simultaneous climax.
In that instant, Diena finally grasps the implications of Mizuki's inventions, and Ururu thereby achieves her family's dream.
This, to my mind, is the crux of the entire series. Here we realize that "brothel expert" is not Mizuki's game-breaking cheat skill. Instead it's simply a powerful tool. Mizuki's true cheat is his everyday modern pervert's familiarity with our era's endlessly variable sex culture. Prior to his arrival in this new world, it had apparently never occurred to anyone there that sex could consist of anything other than the reproductive insertion of a male penis into a female vagina. In demonstrating the paizuri and intercrural friction, Mizuri has, for the first time, broken that conceptual barrier. Diena, at least, now understands that sexual release and pleasure can be be obtained from other forms of contact.
The art won over immediately. Mangaka Shiina Kazuki indulges an obvious fondness for curvy female bodies, rendering them with an appealing combination of clean-lined precision and palpable heft & volume. The more explicit sexual imagery is lovingly detailed, smoking hot, and only minimally censored. Since Ururu is a cow girl, we also get a fair amount of lactation fetish service. While I'm not generally a milk man, it didn't get in the way here. My only real complaints have to with the size of Ururu's breasts, which verge on the ridiculous, especially when she's shown having sex with the shota-size Mizuki, and with the sex-to-story ratio, which tilts a bit too hard toward the former. Damn good stuff though.
Chapter two, which I'll cover more quickly, concerns the effect of the brothel's new employees on its internal status quo. Beluna, a proud and wildly beautiful young kemonomimi tiger girl fallen from noble station, feels both eclipsed by Ururu's rise and professionally limited by her own intractable aristocratic arrogance.
Understanding that she must adapt in order to survive, but unable on her own to effect the necessary change, Beluna demands that Mizuki help refine her skills as he did Ururu's. Diena agrees, and Mizuki again comes through, inventing both the handjob and blowjob. He carefully trains Beluna in these arts, repeatedly pouring himself down his student's eager throat and deep within her pulsating kitty. He also helps her find satisfaction in roles & play she would typically reject as embarrassing, humiliating, or beneath her station. Without sacrificing her dignity and essential character, Beluna experiments by dressing as a maid, providing sexual service on demand, exposing her body and its desires to Mizuki's gaze, and allowing him to treat her as an object.
Her filthy hot journey of self-discovery results in another A+ chapter. Beluna's white tiger design is striking, and her body, though appealingly thick, is gravure tight and cheer squad flexi. She may lack Ururu's innocent charm, but more than matches her physical appeal. Plus bonus points for the lack of gruesome fetish content. There's some fairly dramatic squirt & gush toward the end, but I'm into that.
With her staff conflict resolved, Diena considers expanding Animal Girl's offerings by adding kemonomimi types and cosplay options. As if on cue, a towering, armor-clad, dragon woman warrior named Luxa drops in. No one in this series is ever given an age, but Luxa seems a good deal more mature than Ururu & Beluna, though younger than Diena, exuding unshakeable oneesan confidence. She can also make costumes out of her castoff scales, which seems convenient.
It's hard to believe that someone so powerful and self-possessed would choose to spend her life inducing cheap genital convulsions in a small-time ear girl joint, but since Luxa seems intent on doing exactly that, Animal Girl's resident expert steps in to assess the merchandise. This time, however, he's as much student as master. Even stripped for inspection, Luxa remains coolly dominant, flaunting her perfect body while toying with her diminutive inquisitor. Mizuki responds deferentially, gently licking and fucking only what Luxa offers, slyly leveraging the horny dragon's own escalating pleasure against her control of the situation.
He eventually manages to flip the power dynamic, coaxing Luxa into cum-glazed, cock-sucking submission - all so so that in accepting his dominance she might come to understand a lizard woman's pleasure. I should mention here that I fucking hate that bullshit trope and found this a dull chapter that merely repeats in debased form what we previously saw with Beluna. Again, Mizuki has forced a proud woman to bow before him, supposedly for her own good. But here, we never got any insight into Luxa's motives, and the transformation utterly betrays her character. It's like she doesn't even matter. Worse, the sex never catches fire. Was this chapter written for guys who fantasize about breaking giant girls & dominatrices? I dunno. It's not the worst, but not for me.
Wandering through town on his day off, Mizuki is waylaid by a pair of "sex spirits" (wingless succubi, more or less). Demanding that he spill Animal Girl's trade secrets, the spirit girls strip down to offer something in return. Mizuki's zipper bulges with tender compassion as he begs to help.
The girls introduce themselves as Rhea & Bell, sister prostitutes who survive by feeding on the sweet sap that rises from within a man's most ardent affection. Unfortunately, business has of late become so poor that the pair now face starvation. Animal Girl's surging popularity hasn't helped, but nor has the curse of eternal vaginal dryness borne by all sex spirits. The boys, it seems, don't want to fuck sand.
Mizuki announces that he can remove the curse, while warning that it won't be easy. True to his word, he instructs Rhea & Bell to commit sibling incest and masturbates on them as they gently violate the laws of man and nature. Miraculously, this works. Upon receiving the blessing of Mizuki's sperm, each girl's sister-kissed spirit slit instantly begins to ooze with joyful lubrication. Mizuki then introduces them to Diena, who suggests they partner with Animal Girl for ear-equipped cosplay sessions. Hooray for capitalism, everyone wins
Mizuki pays an overnight visit to Ururu's family, meeting her mother Aruru and little sister Eruru. The latter is cute as a tsun-button, but is whisked off to bed by Ururu shortly after dinner. Rather than either of her daughters, this chapter concerns Aruru, a widow in her sexual prime who's spent far too many nights alone. Seizing the opportunity presented by her well-hung guest, she slips into Mizuki's bed in the middle of the night.
Though perhaps dimmed by years spent in service to her family, Aruru's charms still smolder, and Mizuki gladly spends the night pumping clover. While I'd have done the same, Aruru's abundant acreage threatens to engulf the twiglike shota lodged in her lady bits, which makes the spectacle of their congress rather more odd than erotic.
This chapter has moments, and I quite like Aruru as a character, but the proceedings are further marred by nipple fucking and other grotesque distortions of erotic anatomy. While such hyperbole is common in plus-size milf kink manga, I've never been able to understand the appeal. It turns everything into Dr. Suess with cumshots.
We find Mizuki in his workshop discussing his many amazing inventions, including lotion and the dildo, with a nameless dark elf masochist. They then proceed to stick various uncomfortable-looking objects in & on her body in preparation for an evening of Holland Tunnel anal gaping. This chapter is the actual worst.
Mizuki uses his huge, curse-destroying penis, along with various other strategies, including nipple fucking and full-arm multi-hole internal handshake fisting, to assist a lady afflicted with boobs the size beanbag chairs. I cannot in good conscience recommend that anyone read this.
Following several chapters away, we now return to Animal Girls, where Diena has hired fresh talent and expanded the facilities to include a large, dragon-heated bath. The latter, of course, inspires Mizulki to invent the soapland. Diena, ever-alert to potential profit, agrees to test out the idea, giving Mizuki two new girls to train: Rabii, a hardbody sports rabbit, and Chul, an imouto-type oppai loli puppy girl.
Together, they explore many of the traditional soap disciplines and conclude with an affectionate three-way that does not involve any fucked nipples or gaped anals. Rabii provides adequate support, but this chapter's heart and hard belong entirely to Chul. While painfully shy, she's clearly nursing a huge crush on big bro Mizuki. The image of her blushing face as she bravely spreads the pink for oniisan's cock is a series high point. Excellent work all around, and a welcome return to form.
Presenting the long-awaited return of best girl Beluna, who seems for reasons unknown to have changed her name to Berna, a development which sucks and will henceforth be ignored. Animal Girl's tiger princess, still dressed in the maid outfit from V01 C02, now wants to learn her way around the bath. Mizuki, sensing that Beluna would excel as the type of soap girl who angrily tolerates unpaid creampies and pisses in the customer's face, helps her hone the requisite people skills. God I love this woman
As described above, the first half of the chapter details the hottest, sweetest kitty fuck seen since volume 1. In the second half, however, boss lady Diena arrives bearing a living double-dong of some unholy sort. With Mizuki's help, she tests the vile thing out on Beluna, resulting in a nauseating round of Lovecraft lesbianism. I would normally abjure such filth, but instead skimmed the offending pages with a song in my heart, buoyed by the loveliness that came before.
Luxa, having settled into her new career, prepares to entertain a truck-sized centaur packing a rod bigger than Mizuki's entire body. This is, yes, more of that anatomically implausible John K. Peta shit, but for once, it's fire ❤️🔥
Luxa's clearly aching for it, she looks incandescent when impaled, and I have no problem seeing a bad bitch dragon warrior take a cock that would split a human woman in two. This is in part due to the unique physical structure of Luxa's reptilian cockbox. We see in this chapter that it's much less human-like than I had previously thought, with a design that allows dragon women to comfortably handle the stupendous phallic yardage of their men, next to which mere centaurs apparently seem puny. Weird detail, but kind of cool.
Once Luxa gets her fill, the action switches to a private party at which a kemono puppy boy shota is made to repeatedly fuck, knot, and empty his furry little balls into the incest-prone lust spirit sister duo from V02 C02. I'd been secretly hoping for some filthy beast action since the beginning, but never thought we'd actually get it, much less both horse & dog cocks in a single chapter. 100% my kind of kink, A+ all the way.
V01 C03: Churu, Animal Girl’s scullery pup, wishes he could be of more use to the brothel. Mistress Diena obliges by TSing him permanently into a short stack oppai loli, then hands him/her over to Mizuki for the inaugural stretching session. Hot pink sex crimes ensue, with a special emphasis on involuntary urination, which might trouble people who are not me, so be advised. I personally found this chapter to be delightfully gay.

V01 C04: Olfida, a chaste Elven nun, is so deeply offended by Animal Girl’s degeneracy that she challenges Mizuki to a sex contest – with the brothel’s future at stake. Once saddled up, however, Mizuki quickly sees that Olfida is (surprise!) a massive maso prevert. He helps usher her through the gushing gates of heaven, the day is saved, and Olfida decides that a little recreational whoredom might not be so bad after all. You know, every once in a while. For God.

V01 C05: It’s payday at Animal Girl, and foxy boss lady Diena finds herself in rut. She turns to Mizuki for comfort but informs him with no little sorrow that an ancient curse has left her unable to climax. Thinking fast, Mizuki realizes that it probably wasn’t an ass curse and invents anal sex. Diena cums like a freight train, squirts up a storm, and the pair of them enjoy a night of festive reaming. Love this ❤️

V01 C06: A young Holy Inquisitor drops by to investigate rumors spurred by Animal Girl’s soaring popularity. Diena invites the boy to sample her house’s wares before passing judgement, then deposits him in the care of Beluna, fitness bun Rabi and Churu (whom I wish to call Churro but will not). The trio sucks, fucks, rides and pais their guest to the brink of fatality, upon which the Church grants its semen-stained seal of approval.

V01 C07:[pt. 1 of an unrelated story set in the modern world] Hoping to use it as a guardian slave, a young exorcist named Takeshi rehydrates an ancient Egyptian mummy. The creature, a minimally-wrapped demon loli named Mami, announces that she will accept Takeshi as her master only if he first fucks her into submission. So they do some U12, Mami swoles herself to adulthood with a showerhead, and then they do it some more. A lot more. Str8🔥

V01 C08: Just as things are getting good, a big ol’ oni gal comes smashing in and wrecks the place up. Luckily, mummy Mami subdues her before any real harm can be done, and Takeshi avails himself of the opportunity to rape the sweet lord Jesus out of their captive intruder. Unfortunately, this involves nipple fucking and goes on for quite a while before Takeshi finally recognizes the semiconscious maiden he’s been perforating as Miki-chan…

V01 C09: …his long-lost childhood sweetheart! Oops. So they all have crazy threesex to patch things up. Mami demonstrates her ability to lolify when convenient, wedding bells ring in the distance, and it’s all so dang cute that even some weird prehensile bandage penetration (a la Tsugumomo) and John K. Peta-style uterine prolapse action can’t entirely ruin it. The end.

V01 C09.5: …Volume-closing tankoubon content, including a short but sweet omake chapter.
This is funny but if you aren't into fatties and/or women with obscenely large asses/thighs, this might not be the fap material for you.
Dropped, as I don't find the visuals appealing, but if you have a tolerance for that, go for it, it's fun!
