These Kois are a type of Fish creature that has been around since humans are around. similar to other fish girls, they rarely surface or appear. but can learn and live with humans with not much hassle. unlike their rugged independent relatives, carps, Koi girls are more submissive, and prefer to follow orders.

these fish girls have slippery skin, a human-like body, and gills, though they are able to breathe air for a very long time. Unlike their relatives or similar bipedal fish, There are no known male kois (yet...!), as of now, all the known discovered koi people are always females. perhaps they are around but either dont live as long, or dont surface as often.

before we start to go in depth, we need to know the basic things every koi hybrid needs.

Pools/Bathtubs

Fish Girls are Fish, they require a place to submerge. knowing that these koi fishes will live most of their time outside of water, you dont require any large installations. a simple bathtub will do just fine. but bigger can be better. the bigger the pool they live in, the happier they will be. though not necessary, its prefered that you have two places for them to submerge in. they will use one to rest, and the other for breeding purposes such as egg laying, masturbation, ect.

Food

this is an obvious one, but these fish obviously need foods. fish food is an alright source of sustenance if money is scarce, and you cant afford to buy food for 2. in which case, you will hold atleast a handfull in your hands in front of them, and your koi will usually feed from them. now although this is easy, it is obviously more better to feed them real food. your koi will feed on anything edible in their mouths. they can eat most meats, and luckily theyre different enough from their fish cousins that they can eat fish meat without any issue. so you dont need to cut out fish from your diet.

Clothing

though you could just leave them to wander naked on your house, it is obviously better to have them wear clothes. though their skin are slippery, theyre not wet. so you can just give them clothing. usually they will remember to take off their clothes before they return to their pools.

Sex toys (optional)

of course, you can always have sex with them, but what are the chances that you are always ready for sex all the time? These sex toys would hopefully give them enough sexual release if youre not in the mood, or is not avaliable. get the basics such as a vibrator (for their nipples and their vagina!),and a dildo. these will usually be enough for them.

Koi girls are known to be submissive, and will usually let you do whatever you want to them. However, make sure to have proper consent between you and your koi! this ensures a good morale between both of you. Koi girls are also known for their higher libido compared to other known fish girls. so Sex is something you will experience often.

there are many sexual things you can do, but for the sake of simplicity, we will seperate them to two categories.

Service/Carressing

these activities include blowjobs, hugs, cuddling, handjobs, titfucks, and so on. these will usually be used to get both of you 'excited' for sex. though you can also do it just to make them feel happy. if you dont feel like having sex, you can always just carress them sexually. though they wont be as satisfied, they will be happy enough that they wont be as pent up as before. foreplay is as important in sex as the actual penetration, since its to prepare both of you for what might be the best feeling pussy you might feel...!

usually, their most sensitive parts are their fins, their breasts, their bellies, and their heads and mouths. so these might be the things youre aiming at during foreplay.

Penetration

penetration is obviously putting your penis inside your koi fish. if this is their first time, you have to do it in a slow and gentle manner, and slowly speed up. if theyre more experienced in sexual favours like these, you can go as hard as you can, but dont go too hard that it harms you or your koi fish!

what does it feel like, you might ask? well, its somewhat hard to explain, but it is the best thing you might feel. koi fish pussy are usually very tight (in a good way!), slippery, and warm. lubrication is rarely needed since their pussy is already lubricated in the first place. because of how slippery their pussy is, you might find your dick slipping out a couple of times. once you get used to the rhythm of how things work, this will usually happen less.

Lactation is a normal thing for most kois. unlike us mammals, koi girls produce milk naturally without the need to breed first. it is assumed that they do this during mating in their usual habitats. though most kois ignore or find pleasure from this, some kois experience mild discomfort from lactation.

one way to ease their discomfort is by giving them breasts pumps to aid them in lactation, but personally, i think the best way to comfort them is by sucking on their breasts. it usually makes them calm down easier, so you should atleast try to do some breast suckling... if you dont feel like it however, milking them like a cow is always good enough. just squeeze and milk their breasts like you would do to a cow, and milk will start to pour out from their breasts. this is usually very orgasmic for your koi friends, so proceed with caution!

once theyre done lactating, they usually end up tired, but still very pent up from all of the breast teasing. in which case, try to do foreplay gently. this will ease their horniness, and will usually make them fall asleep. in which case, slowly bring them back to their resting pool, or any other place they like to sleep on.

Egg Laying isnt really a painfull process, however it is tiring and uncomfortable. it doesnt matter if they are fertile or not, koi girls will start this process regardless. a healthy koi will usually lay up to 5 to 10 eggs. usually human with koi relationships wouldnt create a fertile egg, so you dont need to worry on starting a family. Kois, though still submissive, will begin to become abit more territorial afterwards, especially with their eggs. because of this, they might growl or become hesitant on meeting guests, so try to keep them alone for the time being until they feel comfortable again.

though rare, some koi fish might be really obsessed with your cum. pleasing them and their obsession is very simple.

jacking off will usually make your cum obsessed hybrids satisfied. the sight of you cumming is enough to make them euphoric. cumming on them can also satisfy them too.

Like any other social animals, koi girls appreciate talking with other people, and especially other koi girls. of course, they will try to avoid ones they deem dangerous, such as most carnivores. However, given enough time, you can successfully socialize your koi girls to anyone! one of the best combos you can have is a carp and a koi. the carp, as compared to other fish girls their size (the koi, cat fish, ect) tend to be the most dominating. they are very independent, and though would happily have sex, tends to be more harder to control. This is the perfect partner for your koi, if you feel like you're unnable to give your koi constant attention. the carp, being a dominant independent fish, will happily interact and have sex with your koi, while your koi, naturally submissive, will enjoy following the carps orders.

here are some questions that i get often,

Can i make my Koi a Dom? - you can, though it takes a long time to do.

Would my koi do strange kinks that im into? - if it makes you happy, then it will make them happy too. your koi would probably be into any kinks that you're into, as long as its not too extreme or mentally taxing towards them.

can a koi be angry? - they can, and they usually get angry if you give them less attention towards other koi or people, and many other things. angry koi will usually be less obedient and tend to get loud.
