Guide to corruption related tags and ideas
So there's a number of tags and ideas on this site that have a strong relation to my favorite tag, corruption. Most of the folks here have an understanding of the tags/ideas, but some may not have had enough experience with the games involving them to understand them fully, or have simply not spent much time thinking about them. I'm going to go over those tags/ideas (including corruption itself), explaining in detail what they are and how they are commonly used, based on my experience, NOT necessarily the official description on the site. This will be done from a heterosexual point of view, but in most cases you can swap genders/sexuality/genitals without issue.
Corruption
In essence, the girl becomes a slut. Slut specifically meaning she loves sex. How much of a slut, who (or what) she becomes a slut for, how innocent she starts off as, her libido, as well as how fast the corruption takes, are all variables that change based on the work. There are times sexual corruption is tied to moral corruption as well, but this is much rarer and involves something like (non-sexual) drug use reinforcing reckless behavior, or poor self-esteem from being abused causing her to feel she might as well become a slut, as that's what she deserves.
Most sexual works of a decent size contain at least some corruption aspects. A girl can be corrupted or lead to corruption by just about anything, such as drugs, mind control, rape, big dicks, manipulation, blackmail, or even positive means like love, care, and good sex. As long as she becomes a slut over time for at least one person or thing, then it qualifies.
In most games featuring corruption, there is a sense of progression of the corruption. As a rule, the more the change from start to finish, the more satisfying the corruption. A sense of shame, regret, or resistance is almost always an important part of this progression. Sometimes there are actual tiers with numbers, sometimes a lewd/corruption/lust stat number, and sometimes a less obvious progression based on internal game variables. The following is a rough example of a corruption tier system.
Corruption Tier:
0 - Complete Innocent. Knows nothing and experienced nothing about sex (that they are aware of). Completely trusting and will not even be aware that a sexual interaction is happening. Due to this, these girls usually never move from this tier naturally. Arguably, because there is no sense of shame or awareness, these girls are incapable of being corrupted, no matter how much they come to love cock. Not realistic for girls without serious mental defects or MASSIVE mental trauma. Also very, VERY rare.
1 - Dangerously Innocent. Knows very little, but is vaguely aware that sex exists. May have experienced some very mild sexual interactions, like a lustful glance at her. Sexual desire either doesn't exist or is completely repressed. May not be aware of most sexual interactions and typically is trusting to a fault, but is at least dimly aware that something's up, even if they don't know why. Most girls portrayed as truly innocent usually start here, because at tier 0 they are basically insane.
2 - Naive. Knows that sex exists, but is ignorant of a lot of details. Very little experience, but may have been groped or sexually harrassed. Any sexual desire tends to be heavily repressed. Starting point where the girl will be highly defensive and feel a deep sense of shame for engaging in any sex act, though often will be tricked or manipulated into it. Most corruption works start a girl here because there's a better sense of progression then tier 1 or 0.
3 - Normal. Knows about sex, and may have had a wide variety of sexual experiences. May enjoy sex quite a bit. Still feels some shame for non-typical sexual experiences, but may not feel any for routine ones with someone trusted. Still resists casual sex with (unattractive) strangers. Basically a typical girl in reality, and highly variable in details, though trending towards more innocent rather then less.
4 - Lustful. Knows a lot about sex, and either has had a lot of sexual experiences, or wants to. Enjoys sex a lot and seeks it frequently. May still feel shame in certain cases, like cheating, but lust tends to win out. May engage in casual sex, even with unattractive people she wouldn't normally have sex with. This point may mark fallen status in some works and the end of the corruption chain.
5 - Slut. Almost complete knowledge of sex, and has had a lot of experience. Craves sex constantly. Shame is either gone completely or is only a minor annoyance, and lust always wins out. Engages in casual sex constantly, and would prefer taking a cock to any other activity. Still possible to have a normal life, but heavily distracted and if cheating likely to be caught. Most works end the corruption chain here.
6 - Cock Slave. Knows everything and has done everything worth mentioning sex-wise. Completely addicted to sex. No shame whatsoever, and takes perverted glee in doing taboo acts. Will have sex with anyone, at anytime. Can no longer have a normal life, because they can't stop having sex long enough. In extreme cases, may not be able to survive without help, as they forget to eat/drink/sleep/breath. Its rare to see this tier except at the end of the work, since there is no more corruption possible at this point.
For all tiers, the girl's corruption may either only apply to one person or group of people or be heavily limited except for them. Any aspect of a tier may also be mixed and matched, so a normal girl may have the lust typically found in a slut, or a girl may have the knowledge (but not experience) of a cock slave but in every other respect is naive.
Most corruption works have a fascination with the naive tier, and it has the most potential for corruption in a reasonable time frame. However, if the majority of the girl's characteristics don't move from their starting tier to at least one tier above (usually two), then its a shitty corruption work. The reason being is the sense of progression is a huge part of the enjoyment of corruption works, and if there is no progression, or worse regression, then it feels pointless.
That's not to say that a enjoyable game can't limit overall progression for event chains, so that the girl always starts at naive for instance and becomes a slut by the end of the chain, to ensure the player sees all the events. The main point here is that general events or systems not tied to an event chain need to show how the girl is changing, so a girl for example might wear sluttier clothing as she goes up the tiers, or her facial expression changes.
Finally, its worth noting that despite popular opinion, a whore/prostitute may not be a slut and may belong to any tier. While most whores in works typically start at normal tier or above, since all that is required for a whore is that she sell her body, she may, in fact, be innocent in many or all aspects outside experience and (some) knowledge.
Mind Control
One of the methods of corruption, and is often misunderstood as to the full extent of its possibilities. Mind control isn't simply making a girl have sex using hypnosis or something, but potentially controlling virtually every aspect of how she views and experiences reality itself. Unfortunately a significant number of works just use the mind control to force the girl to have sex, so the misunderstanding is to be expected, but its not limited to that. Below is a list of a FEW ways mind control might be implemented, for all of them the girl may not be aware of the control, and she may not enjoy it, depending on the work.
Types of Mind Control:
1. Alteration of sexual desire - Makes the girl horny (or frigid), may be conditional or all the time. Very common, usually leads to sex immediately, sometimes has a delayed effect.
2. Given order, must obey - The classic "suck my dick" command. Can include any sex act (or mundane action for that matter).
3. Alteration of enjoyment - Makes the girl enjoy things she might not normally enjoy, or enjoy them more. Can also be inverted to lessen enjoyment. Useful for making a girl REALLY love giving that blowjob command above for example, while being disgusted with her boyfriend's dick.
4. Alteration of norms (sometimes called common sense) - Rewrites the girl's understanding of what is acceptable or unacceptable behavior. There's a lot of ways this can go, but as an example may be used to make the girl consider it polite to introduce herself by stripping naked.
5. Alteration of relationships - Rewrites a relationship, in both subtle or unsubtle ways. Often used to make the controller a friend/lover/husband/relative/master. Can be used to make a rival an enemy or some non-threatening status, like brother.
6. Alteration of sense - The girl may see or even feel things as different then what they are. A guy's penis might become a lollipop temporarily for example. Can alter everything, including taste and size, though radical alterations, like turning a tiny dick into a huge one, may cause too much inconsistency with reality.
7. Alteration of will - Controls free will, can be used to remove it completely, compel the girl to do or avoid specific things, or simply push them to do or avoid certain actions without forcing them. Complete removal can lead to a "doll", which is basically a mindless girl who does whatever is asked without resistance, popular in some works.
8. Alteration of memory - Inserts, rewrites, or removes any or all short or long term memories, including feelings with those memories. Can also prevent or promote memory retention. Memory can include skills, such as riding a bike or even walking. Can essentially change the entire person if used fully, or even "kill" the person without actual murder, assuming no soul. Often combined with relationship alteration or alteration of will. Arguably the most potentially evil ability on this list, even if we included literal torture. Also, probably the most powerful on this list, since with enough work it can do what any of the others can, practically speaking.
9. Alteration of emotion - Changes any aspect related to emotion, including when certain emotions are felt and under what conditions. Another ability with incredible evil potential, since removing a person's ability to feel any happiness except when sucking dick would be a pretty awful thing to do.
Some of these are just more limited forms of others. Relationship and norm alteration for example are really just more limited forms of memory alteration. Enjoyment and sexual desire alteration are specific forms of emotion alteration. Given order, must obey is a more limited form of alteration of will.
Limitations are in fact quite useful for corruption because they make things more interesting and add a challenge of sorts for the girl affected to potentially overcome. The fact the girl MIGHT find a way to resist more limited mind control is more interesting then simply seeing her eagerly suck dick as commanded every time. Mind control in this sense can add to the sense of progression that's vital to good corruption.
For example, a simple alteration might be that the girl gets slowly escalating pleasure when complimented by men. Most straight women enjoy sincere male compliments anyways, so the girl even if she is aware of the mind control might never realize its form. It would end up being extremely effective though, because when you think about a girl who'll eventually do anything to get a positive response from men, she would naturally end up a eager slut to do so.
Another interesting aspect of limited mind control is it can also be used to suggest that the girl is really a slut at heart without outright stating that. If the mind control is limited, she could resist if she REALLY wanted to.
This is my favorite method of corruption, if it wasn't obvious. If an author can't come up with a hundred different ways mind control could be used to corrupt a girl, they aren't trying hard enough. Its extremely flexible, and most other forms of corruption will just be heavily limited versions of what mind control can do. In theory, its also possible, since no one fully understands how the brain works. That said, I guarantee, given how humans are, we would know very quickly if such a thing really existed, and no, real life hypnosis doesn't count.
Magic
Fantasy method of corruption, as powerful and flexible as it gets. Can alter reality, rather then just the perception of it like mind control. Lewd crests go here, as well as any means used to inflict mind control that isn't properly explained through some kind of (pseudo)science. Can literally do anything, so putting categories here is pointless. Like mind control, tends to be under-utilized in its potential.
Bimbofication
A very specific form of corruption. Typically altering a woman so she has big breasts, plump lips, blonde hair, and empty head. There are variations, but if she isn't attractive and stupid, then she's not a bimbo. Often involves either a lot of plastic surgery, or outright magic, along with mind control.
NTR
Ok, I didn't put this in here just because its controversial, but because it has a lot of overlap with corruption. The definition here isn't going to be simple, but I'll try. First, there are three main types, and the types are different enough that the definition of NTR changes based on it. As below:
1. Netorare, or classic NTR - Situation(s) where due to some sort of relationship or attachment, the character/player/viewer feels a sense of sexual jealousy (and arousal) as a girl is used sexually in secret by another man or men and is often "stolen" or ends up in a relationship with the aggressor(s) and sometimes ends the relationship with the cuck. Usually follows the male character who's getting cuckolded, and he usually doesn't know about the secret relationship(s). Also tends to be made in such a way that even if you don't care to be a cuck, you can focus on the girl or aggressors and enjoy it that way.
2. Netori, or cheating NTR - Same as Netorare (minus sexual jealousy), but more emphasis is placed on the perspective of the guy(s) stealing the girl, or the girl herself, with little regard for the cuck. Very similar to the cheating tag, though usually with small bits of information about the cuck, often to point out in some way how pathetic he is. The opposite of "sexual jealousy" occurs here, as the viewer/player identifies with the thief(s) or corrupted girl.
3. Netorase, or complicit NTR - Same as Netorare, but the cuck knows whats happening and encourages it. Usually doesn't intend the girl to be stolen. Almost always focuses on the male cuck, even more than classic NTR. Sexual jealousy isn't just what occurs, but is the point of his encouragement. Occupies a strange spot, since it tends to leave both netorare and netori fans mystified, as in "why would you do that?!".
So what's the connection to corruption? Let me answer that with a question. Why do you think the girl is screwing the aggressor in the first place?
In most stories the girl is no higher then normal tier, and often is on naive tier. She's usually leading a happy life with the cuck, though the sex part is almost always lacking. The aggressor opens her eyes to the pleasure of sex, but before he gets there he has to gradually wear down her defenses, trick her with guile, or use brutal means that she ultimately ends up enjoying.
Basically NTR provides an excellent reason for the corruption to happen. You can have corruption without NTR, but its a rare work that has NTR without corruption.
Drugs
Another method of corruption, drugs refers to pretty much any substance that causes arousal, lowers inhibition, or alters thinking. Usually addictive, but doesn't have to be. I'm putting male cum in this category in those cases where it has a strongly addictive or arousing effect beyond what one would expect. Monsters often have addictive cum, and it can be fun to see a girl gradually desire this cum more and more even if she's initially disgusted.
Big Dick
Method of corruption which is exactly what it sounds like. Interesting thing about big dicks though is its a more "natural" form of corruption then most other methods. No weird drugs or magic spells or mind control. It also doesn't usually require any negative action taken against the girl, just an excuse and exposure, accidental or otherwise. This situation does require that the girl in the work has a big lust for big dicks, so its still not highly realistic.
Wealth, Status, and Beauty
The most prominent real life traits that corrupt, also "natural". Wealth and status almost always is corrupting exclusively to women, while beauty corrupts both. Ask a woman whether she'd fuck her favorite media star. Since porn tends to be escapist in nature, these tend to be downplayed except when it would make the object of lust more attractive. In porn for women, expect a LOT of wealthy, powerful, attractive men. For men, expect good looking women.
Blackmail
Use of secret info of some kind or inherent authority/power to threaten the girl into compliance with (sexual) demands. The classic path to corruption for villains everywhere. The blackmail material itself can be extremely flimsy at times, such as "I took a photo of your panties, now give me a blowjob!". In better works, the threat will be a lot more meaningful, such as firing the MC/girl, exposing a secret that will get the MC/girl put in prison, etc. Doesn't usually sexually corrupt in and of itself, except perhaps in a moral sense, though the guilt and shame from the (initially) forced acts may lead the girl to accepting her fall.
Manipulation
A path to corruption, not an actual tag but important to note. Usually combined with blackmail, but doesn't have to be. Essentially a lie or misleading truth that convinces the girl to do something, usually sexual or to setup a future sexual situation. Other methods of corruption, like libido drugs, are typically used once the girl falls for the manipulation. Like blackmail, doesn't corrupt itself, but the consequences may lead to moral corruption and ultimately acceptance of her new role.
Pleasure
Not a tag, but important. Ironically, its probably the biggest method of corruption. Despite all the fancy, devious work the aggressors often do, what usually corrupts the girl the most is her own innate enjoyment of dick. Some works enhance this enjoyment through artificial means, like aphrodisiacs, but for many works, it comes down to her simply enjoying getting fucked. This corrupting pleasure is also why positive acts can corrupt. The girl may have lovey dovey sex again and again, and the pleasure she gets from that can transform her into a dick loving slut.
Conclusion
Hope you enjoyed that. I'm sure there are more examples of corruption methods and types of corruption, but this guide should cover most of them.

In better works, the threat will be a lot more meaningful, such as firing the MC/girl, exposing a secret that will get the MC/girl put in prison, etc. Doesn't usually sexually corrupt in and of itself, except perhaps in a moral sense, though the guilt and shame from the (initially) forced acts may lead the girl to accepting her fall.
Manipulation
A path to corruption, not an actual tag but important to note. Usually combined with blackmail, but doesn't have to be. Essentially a lie or misleading truth that convinces the girl to do something, usually sexual or to setup a future sexual situation. Other methods of corruption, like libido drugs, are typically used once the girl falls for the manipulation. Like blackmail, doesn't corrupt itself, but the consequences may lead to moral corruption and ultimately acceptance of her new role.
Pleasure
Not a tag, but important. Ironically, its probably the biggest method of corruption. Despite all the fancy, devious work the aggressors often do, what usually corrupts the girl the most is her own innate enjoyment of dick. Some works enhance this enjoyment through artificial means, like aphrodisiacs, but for many works, it comes down to her simply enjoying getting fucked. This corrupting pleasure is also why positive acts can corrupt. The girl may have lovey dovey sex again and again, and the pleasure she gets from that can transform her into a dick loving slut.
Conclusion
Hope you enjoyed that. I'm sure there are more examples of corruption methods and types of corruption, but this guide should cover most of them.
