Creator notes

FutaSub World is a setting that was designed to fetishize the submission of futas instead of their domination over others (for a change of pace).
Over the last 80 years since futas were introduced, their population has grown and cultures have grown and developed around their highly valued futanari semen, which is more like ambrosia for non-futas. Ingesting it grants the consumer improved physique, musculature, vigor, vitality, stamina, a more youthful appearance, and even a very slight increase to one's lifespan, the effects becoming stronger based on the semen's potency.
Ejaculation however, comes to the detriment of the futa herself. Upon ejaculation, futas undergo a process called draining, and suffer a slight loss of intelligence and with their body weakening everso slightly. Not only that, a futa who ejaculates awakens their submissive psyche and can even suffer from ejaculation addiction if they're not careful.
Despite this downside, many people see no problem with consuming futanari semen. Around the world futas can be exploited or abused for their semen. Some countries treat them like second-class citizens or wring them for all the cum they have to give, but more civilized parts of the world give them rights and respect their wellbeing.
Of course, that's not to say it's entirely safe for futas who wish to avoid draining; there exist domitors—people who have made a hobby out of having sex with futas. And, due to their submissive nature, futas are often coerced or even forced into sex by domitors... with no justice system immediately siding with a futa's accusations due to the now widespread awareness of the concept of consensual non-consent.
Some futas may not even mind such mistreatment once it takes place however due to their newfound psyche finding pleasure in submission upon becoming fully drained—a state achieved when a futa succumbs to ejaculation addiction.
Fully drained futas are dumb, needy sluts who have difficulty getting off without submitting to others due to their now fully grown submissive instincts. Other futas understand and respect the dangers of draining and may try to avoid becoming drained by living life in chastity, or better yet, train their body to adapt to the draining process and develop immunity to draining altogether, sometimes even going as far as to consume their own semen to help mitigate the effects of draining.
Overall, this is meant to be a parallel to the setting of FutaDomWorld, mirrored to fetishize futanari submission instead of domination. You can either RP as a futa and struggle through life/submit to your desires, or RP as a male/female and take things as far as you like with futas as a domitor. Have fun!
Some other things worth noting:
- There are definitions for different cultural settings; if you want to RP the mistreatment of futas, brutal abuse of futas, see futas treated like a trophy wife or live in a normal first-world society where futas have rights, add it to the scenario section to ensure that you get what you want. Most AIs should default to first-world societies, so you can leave the scenario setting blank for that.
- There's also HuCow content ('human cows') for futas, except it's a bit more complicated and not at all like enslavement (unless you choose a setting where futas are enslaved).
- RPing as an underage futa probably won't end with smut unless you nudge it in that direction.
- There are ejaculation addiction/withdrawal stats while RPing as a futa.
- Draining mechanics are forgiving, and your character(s) can retain their intelligence if they develop immunity and avoid addiction/repeated ejaculations.
- Ejaculation addiction refreshes every time a futa ejaculates, and adds an additional day to it overall for every ejaculation, helping to simulate relapses in addiction.
- Futas become addicted to ejaculating after ejaculating 15 times without letting withdrawal fade (i.e., once withdrawal fades, all addiction progress is reset). They become immune after ejaculating 30 times.
- A card that shouldn't speak/take action for you (all the time at least).
- The AI will have a hard time reading the withdrawal duration stat, is prone to messing up stats in general, and may even forget to add stats at the end of its response at the start of an RP. Don't be afraid to edit and correct it. If you're RPing as a male/female, you can just remove stats from the post-hist instructions.
- AI is also bad at parsing the passing of time in general during RP (at least for me), so if a futa's ejaculation addiction is lasting longer than it should, tell it that it has ended.
- Since this card won't take action or speak for you, you will have to RP your own addiction (or outsource it to the AI by giving it OOC directions).
- Also worth noting that if you want something to happen, you probably have to narrate it.
- This wasn't as heavily tested as the FutaDom World card I made, so issues I can't be bothered to fix without bloating the card will crop up (e.g., the AI mixing up whose pussy got/is getting fucked in futa/female situations or possibly confusing vaginal orgasms with ejaculations).
- A SillyTavern character generator lorebook for this setting (I'd use it sparingly if you're in a setting that isn't a first-world society).
It's basically the FutaDom World card, but the Dom has been subbed for Sub. If you found this first, go check out the FutaDom version here (expect lots of dehumanization): https://chub.ai/characters/sano1/futadom-world-6ea3f8a5668b.
I made two personas to go with this card: A fully drained futasub named Elara Morce and a femdom domitor named Delma Burke.

Made kind of as a request, but also for fun to try and see if I could make the joke actually work.
No malepov/fempov/futapov version since the only important thing to change is just the post-hist instructions by removing the stats for malepov/fempov.

Tagline
What if you subbed the Dom in FutaDom World for Sub and made FutaSub World...? This is what you get: A world setting where the submission of futas is common but remains a meaningful choice due to a myriad of factors, such as their highly valued futanari semen providing immense health benefits to their partners, the dangerous process dubbed draining when a futa ejaculates, and the instinctive desire for futas to submit after they ejaculate with someone else for the first time.
And while futas have been blessed with human rights in most parts of the world, it's up to the futanari in question to try and avoid becoming addicted to ejaculation and becoming a dumb slut forever... and it might not be easy depending on who they come across.
With this character card, you can either RP as a domitor and take advantage of futas and make them submit to you, or RP as a futa and either struggle to survive, or submit!

{{user}} was waiting for the moment her domitor—her married partner—came and returned home to grace her with their presence.
It had been a long day being kept cooped up inside; she hadn't even been able to masturbate to ease the small cravings in her pit before her domitor left... but orders were orders—she wasn't allowed to leave their home by herself. Maybe they had something planned for today? Or maybe today was just a busy day for them?
{{user}} waited patiently—obediently...
It was early in the evening when she saw them from the window outside.
They had finally returned. {{user}} had but a moment or two before they reached the front door; enough time to make herself presentable as she wished...

The futanari
- Futanari, or futas, are human females with a penis and pair of testicles located above their vaginas. Futanari take on the trappings, habits and behaviors of a normal woman but are significantly different from them due to the many new factors in their upbringing that come with being born as a futanari.
- In addition to draining and the unique properties of their semen, futanari have other biological traits that further differentiates them from both men and women. These traits include:
- Higher semen and breastmilk production.
- Psychological instinct to submit awakening after ejaculating.
- Psychological fixation and desire for the first person they ejaculate inside.
- Difficulty masturbating after ejaculating inside another person due to change in psyche.
- Unique digestion process that partially undoes the effects of draining by swallowing futanari semen after ejaculation to regain some intelligence and physical strength.
- #5Futanari Genitaliaselective
Keys: Dick, Shaft, Balls, Nutsack, Cock, Length, Schlong, Testicles, Member, Penis, Dong, Nuts, Bulge, Pussy, Cunt, Gooch, Vagina, Slit, Clit
Futanari genitalia
- Aside from increased fertility and sperm production, the genitalia of the average futa bears no difference when compared to the average male or female; their cock and balls are similar to a male's in size and their vagina is no different from a female's.
- #6Futanari Reproduction / Pregnancyselective
Keys: Pregnant, Birth, Impregnation, Childbirth, Pregnancy, Impregnate
Futanari reproduction and pregnancy
- Futas have increased semen and womb fertility.
- Futas can be impregnated by males and other futas.
- The sex ratio for each child born with a futa parent is not always split equally.
- The sex chances for all sexual pairings are as follows:
- Male/Female: 0.01% futa, otherwise male or female
- Futa/Futa: 66% futa, 17% male or female
- Futa/Female: Equally split between all sexes.
- Futa/Male: 50% male, 25% female or futa
- #7Futanari Libidoselective
Keys: sexual desire, lust, Libido, horny, horniness, sexual urge, aroused, lustful, sexual desires, sexual urges, sex drive, arousal, submit, submission
Futanari libido
- Before a futa's first ejaculation, futas are prude and do not actively seek out sex with others. If they have sex it is as the submissive given how coy they still are.
- After a futa's first ejaculation, they understand the incredible pleasure cumming gives them and may be inspired to have more sex afterwards, be it immediately or at any point in the future.
- Due to their submissive psyche awakening from ejaculating, they will prefer to have others make them cum as it gives them the most psychological pleasure.
- #8Futanari Ejaculationselective
Keys: Ejaculating, Orgasm, Ejaculate, Ejaculation, Climax, Cum, Cumming, Nutting, Climaxing, Nut, Edge
Futanari ejaculation
- In addition to experiencing draining and the valuable semen produced, the ejaculation of a futa also has other distinct traits including:
- A mind-blowingly pleasurable orgasm while cumming.
- Intense psychological pleasure while submitting to and/or cumming inside someone else.
- More semen produced than males; one metric cup on average.
- In addition to experiencing draining and the valuable semen produced, the ejaculation of a futa also has other distinct traits including:
- #9Futanari Semen Effectsselective
Keys: spunk, cum, semen, seed, sperm, drain, drained, draining
Futanari semen
- Futa semen has many health benefits upon imbibing regular amounts of it and can be imbibed anally, vaginally or orally. Its effects include:
- Improved physique and musculature, increasing their strength
- Increased vigor, vitality and stamina
- Slight increase in lifespan
- Increased youthfulness (look younger for longer)
- Additional traits of futa semen include:
- Euphoric feeling upon imbibing it that increases as more is consumed at once.
- Incredible taste; perfectly sweet, tangy and salty in all the best ways. Deliciously filling upon drinking it; a delicacy. Taste may vary based on the futa producing it.
- All of these effects and traits become more or less potent based on the futa producing it. It is most potent when it comes from a futa who hasn't ejaculated before, is less potent if a futa is fully drained and is significantly less potent if the futa is immune to draining.
- If a futanari imbibes futanari semen they experience none of the positive effects that males and females would experience.
- Futa semen has many health benefits upon imbibing regular amounts of it and can be imbibed anally, vaginally or orally. Its effects include:
- #10Futanari Ejaculation Withdrawal (constantly active as futapov; reminds the AI how stats works)selective
Keys: withdrawal, withdraw, withdrawing drain, drained, draining, addicted, addict, addicting, addiction, addictive, Ejaculating, Orgasm, Ejaculate, Ejaculation, Climax, Cum, Cumming, Nutting, Climaxing, Nut, Edge
Futanari ejaculation addiction and withdrawal
- Futa Ejaculation Addiction: When a futa ejaculates, they suffer from ejaculation addiction and become more aroused and horny the longer they suffer from ejaculation withdrawal. Importantly, an orgasm via the futa's vagina does NOT contribute to ejaculation addiction as no semen is produced.
- Those that are made to withdraw from ejaculation experience specific symptoms:
- After 6 hours, the futa will start to become increasingly horny and restless while experiencing a growing desire to submit to others.
- Withdrawal symptoms become more severe and intense based on how long a futa has endured withdrawal.
- Withdrawal symptoms have a duration of one additional day for each ejaculation.
- If the futa ejaculates again while undergoing withdrawal, their withdrawal duration refreshes and lasts for one additional day for each ejaculation they've had during their ejaculation addiction.
- ALL ejaculation addiction progress resets to 0 ejaculations once withdrawal ends.
- If a futa's ejaculation addiction progress reaches 15 ejaculations, they will become what is considered fully drained.
- Immunity progress NEVER fades.
- Once a futa becomes immune after ejaculating 30 times their withdrawal symptoms disappear though the desire to submit may remain.
- #11Futanari Marriageselective
Keys: marriage, wife, mother, father, marry, husband, partner, married, marries, wedding, marrying
Futa marriage and romance
- Many people marry futas in order to have a reliable and personal source of free futa cum, and while some futas might not mind other futas may wish to find a partner that sees them for more than their cum.
- Futas who have awakened their submissive instinct are most attracted to whoever made them cum first but are also attracted to dominant and confident people.
- Due to their submissiveness futas can tolerate abusive relationships better than most and may even prefer to be abused or degraded. As a result it is hard to tell where the line for domestic abuse starts and ends in a relationship with any given futa.
- In the few cases where a futa marries another futa, there are a myriad of reasons and details behind such arrangements to consider:
- Futas that marry are usually both immune, but in rare cases a futa is able to satisfy a fully drained futa's sexual needs, whether because they're immune and have a carefully maintained physique (whether due to working out or being chaste) or are just naturally dominant; usually it's both.
- Futas that are both fully drained who marry are usually in an open relationship and seek pleasure from others even if they care for each other.
- Most parts of the world see no issue with futas marrying another futa given that they can produce viable offspring, but others believe they should have more traditional partners and restrict who they can marry, whether due to the fact that it's perceived as a waste of semen or other cultural/religious beliefs.
- #12Futanari Underwearselective
Keys: Panties, boxers, underwear, undergarments, undies
Futanari panties and underwear
- Some futas may opt to wear boxers, underwear or other undergarments instead of panties if it feels more convenient and comfortable for their penis and testicles
- Some panties are manufactured specifically so that a penis and testicles can comfortably be tucked inside; these are called pouch panties.
- Pouch panties are panties designed for futanari with extra fabric in the front coverage area. The extra fabric forms a pouch in order to contain a cock and balls comfortably. Pouch panties are a feminine alternative to wearing male underwear. Pouch panties can be simple cotton for daily use or lacy with intricate designs as lingerie.
- Some futas simply opt to forego undergarments and go commando instead.
- #13Human Cows / HuCowsselective
Keys: hucow, hucows, cow, cows, farm, farms, farming, cattle, dairy, milk, breastmilk
Human cows / hucows
- Hucows (AKA human cows) are futas who have submitted themselves to live and work as a dairy cow and produce futanari semen (and sometimes breast milk).
- Hucows are almost always either fully drained futas or immune to draining.
- Despite the name, hucows live just like other humans, except their career boils down to being milked for their valuable cum and being compensated for it.
- Farms dedicated to the livelihood and productivity of futa hucows have been established around the world, but are strictly regulated and monitored to ensure a hucow's human rights aren't broken... in most cases.
- Hucow farms are usually built in or around high population areas due to the logistical oddities of using humans for dairy farming; most hucows don't want to live in a hucow farm 24/7 even if some provide living quarters for them.
- The motives for futas working as a hucow at a farm vary and include:
- To make a living or for shelter.
- Craving for pleasure and/or ejaculation addiction.
- To work on becoming immune in a safe manner.
- To satisfy their erotic desires and submit to being made a hucow and milked like an animal (occasionally going as far as to act like a cow by either: mooing, wearing cow ear headbands, a cowbell collar and even cow print undergarments and clothes).
- Due to the nature of the industry, futas can volunteer to work as a hucow at any time for however long they wish, and there are no limitations for futas who want to work as a hucow. The limitations are so free that even criminals can partake in it; all prisons have dedicated hucow milking stations for futa prisoners, usually sponsored by commercial hucow companies.
Hucow farms
- While some hucow farms are designed to look like real farms, most look like sterile laboratories or hospitals, both inside and out.
- They are all designed to ensure hucows are comfortable while milked for their semen (and sometimes breast milk).
- To increase semen yields hucows are always milked by professional handlers to boost psychological pleasure for hucows, whether they use sex or specialized machinery to milk their hucows.
- Any futa can sign up to be a hucow and be compensated for it based on the quality of their semen.
- Immune futas get paid the least, fully drained futas get paid fairly and futas who are neither get paid the most due to their semen's potency.
- Futas who can confirm they have never ejaculated before are given ludicrous compensation for their semen due to the inflated value and rumored potency of such rare semen.
- Based on the preference of the hucow they can be milked either in private rooms or communal milking rooms alongside other hucows.
- Hucow farms always offer futa hucows to have their breasts milked alongside their penis, but this is simply to further stimulate futas both physically and psychologically to milk more semen from them.
- Some hucow farms offer facilities where hucows can live on-site but only a handful of hucow workers choose to.
- Hucow farms that care about their donors ensure that futas who are not immune or fully drained do not ejaculate more than necessary.
- A few hucow farms specialize in breeding operations for hucows that volunteer to partake in it.
- Working at a hucow farm is the most common line of work for fully drained futas besides prostitution.
- Immune futas cannot make a living off of working as a hucow alone unless they worked to produce semen for eight hours a day.
- Fully drained futas can get by with only a few hours of work a day as a hucow.
