Consensus

Before a session, the participants should hold a discussion to come to a "mutual understanding," this being the group consensus.

Even for a normal game, you should talk ahead of time about any supplement rulebooks or house rules you're using, how gruesome at most people's descriptions should be, to what degree your game will follow real-life science and logic, and more along those lines.

And as such, for a lewd game, it becomes important to talk over everyone's sexual preferences. Without a firm grasp on each other's sexual preferences, a session is doomed to fail.

As far as lewd sessions go, no matter how salacious, obscene, or even cruel the act, if everyone participating desires it-- that is to say, it is within consensus, it goes.

On the other hand, no matter how common or innocent something may be, if it's outside of the group's consensus, it shouldn't happen. Even if story developments make something unavoidable, don't go into detail, and just leave it at that.

Consensus is the "golden rule" that should take precedence over the game scenario, rules, setting, and even the GM's authority.

= Going over what's no good = The most important aspect of consensus is to make known what sexual genres each participant absolutely doesn't want to see in the game. As such, each participant should say what is no good for them sexually-- "things they don't want to happen," before anything else. This should be done before the game scenario is designed, before any Hunters are created. For example, if a player says, 「other women are no good」, you absolutely shouldn't have a scenario where any female NPCs come into play! Most importantly, in the case where a GM and player's tastes are beyond doubt incompatible, holding any session at all may be difficult. In such an instance, you shouldn't try to force a session. This is why, before a lewd game, it's essential to go over what is no good. Even if it's embarrassing, you shouldn't skip past it. As well, even if you 「don't know how you feel about something」 as far as tastes, that can also be good to mention to a certain extent. You don't have to be formal about it. Simply chatting about your tastes can work just as well.

What's no good varies from person to person. If something doesn't bother you in particular, it may not even occur to you that it would bother someone else. However, many people have things they don't like that you wouldn't expect. There may be some things people can't stand that you wouldn't even believe. While many people understand that 「you shouldn't do things unpleasant to you to others」, it may not readily occur that 「the same things you like, others may be disgusted by」. Even if you understand that in theory, it may be difficult to act on that in practice with the person before you. Because of that, you need to do your best to be clear with your words, and to acknowledge and respect each other. Even if you didn't expect your partner to not be okay with something, you shouldn't look down on them for it, nor should you go prying for a reason why. An individual's sexual preferences may be intertwined with any number of circumstances or past events. Further, there are many cases where people just like something for no reason in particular, and couldn't explain it if they tried. As well, even if on the surface, something seems like everyone would like it, there are always people for whom it's offputting. When it comes to people's sexual preferences, it's best to assume there's no such thing as a universal taste.

=Going over suggestions= Though not quite as important as what you don't want to see, it's good to convey what you would like to see... that is, some of your own tastes. That said, there are still many people who have sexual preferences that are broad, with not much they're strongly attached to. In such a case, it's fine to simply say you don't have any particular preferences, or you could tell your partner you can go along with what they like. Or perhaps, rather than specifics, you could each talk about your general tastes as far as partners and acts, and use the tastes that everyone participating shares as a guide. As a GM, it's perfectly fine to create scenarios and NPCs based on your own sexual preferences. Of course, as long as nothing you go with conflicts with a player's no goods.

=Specific no goods and suggestions= Asking people's likes and dislikes all of a sudden is bound to leave many drawing a blank. Here are some common tendencies you can draw from, as far as what's no good and what suggestions people may have.

For example, body transformation or disfigurement, bloodshed, abortion, physical violence, and similar are all categories that are offputting to a majority of people. Unless everyone participating suggests otherwise, you shouldn't treat these in a sexual manner. Since these can vary widely in severity, people may wish to say exactly how much is too far for them. For example, if someone only says bleeding is no good, you may not just be able to guess whether defloration is also no good.

Many sexual preferences sit differently with different people. Rape, stretching and gaping, scat, nipplefucking, urethra fucking, hyper breasts, hyper cocks, homosexuality, incest, ahegao, cervix penetration, netori and netorare (cuckolding), gangrape, orc rape, tentacle rape, bestiality, disgusting men, hypnosis, dirty talk, submission, futanari, monster girls, so on, and so on... these and countless others all vary from person to person whether they like them or not. While some people may absolutely love something, for many others it may absolutely be no good. Not only do people's tastes change greatly with the times, an individual's tastes are prone to change as well. Many people, even though something's not outright "no good" to them, may say they're 「not sure how they feel about it」. Without a clear go-ahead, you should at least get a soft agreement from everyone. As a GM, if you want to build a scenario focusing on such a thing, it would be good to talk to your players ahead of time.

The aspects of sexual preference most likely to cause issue are those that, unless you're told, you may not realize or even understand that they could be distasteful. Heterosexuality, loli, shota, adult women, adult men, romance, harems, shame, masturbation, aphrodisiacs, virginity, pregnancy, large breasts, large cocks, sex toys, anal, and more, any of these could, surprisingly, be no good to some people. On the other hand, there may be many who consider these to be quite ordinary sexual preferences. If one of these is no good to you, you should bring it up above anything else, making sure to emphasize it to those you're playing with. It may be hard to empathize with not being okay with one of these, so you should come to your own, earnest conclusion whether 「this much seems fine to go ahead with」.

Differences in values can easily lead to problems in a relationship. You should respect each other's sexual preferences. As long as you can understand each other, you should be able to respect each other. People's sexual tastes are always biased, and it's not a bad thing to not be okay with some stuff. Some people may be fine with everything, but that doesn't make them better than anyone else. If you have exceedingly different tastes and can't see yourselves coming to a mutual agreement, then you shouldn't play a lewd game together. Even then, you can still have fun playing a normal game together with your friends. As far as lewd games go, differences in sexual values alone is enough reason to turn down a game. You don't have to feel guilty for turning down a game because some aspect is no good to you. It's rude to force someone to play a game together. We just need to accept that, as with scheduling and health problems, the circumstances just can't be helped.

=Changes in tastes= As mentioned, people easily change. Sexual preferences are exactly the same. For something no good to become something you enjoy, for something you enjoy to become no good, or even to discover something new about yourself you weren't aware of as far as your tastes-- it's not rare for any one of these to happen during a lewd game. Your own tastes may sour after you experience some partner's play or approach that was as-of-then unknown to you. Things you were fine doing to others, but hated when they were done to you... even those selfish tastes could change. Unlike fictional characters, GMs and players are real human beings. Even without any dramatic event, trauma, or similar, something that was perfectly fine one day, may suddenly become no good the next (as well as the reverse). Even in the middle of a session all of a sudden can things change. People's tastes change from moment to moment. Don't blame them for it. However, don't forget to be honest about any such personal changes in the midst of a session. Particularly if something becomes no good to you, even if it would interrupt the session, you should definitely say so. This isn't something to be ashamed of nor is it a nuisance. Sexual descriptions, both good and bad, can have a profound effect on people. Lewd games are meant to be "play." When playing, you shouldn't have to put up with pain, mental or not. In the middle of a session, people adding on to what's no good should be taken as seriously by others as if they suddenly fell ill. It's not at all your fault if you didn't realize something was no good to you going in. The GM should cut the scene there that conflicts with what is now no good, and quickly move on to the next.

If this happens too often, though, this could be a lack of sexual knowledge on behalf of the person, or it could be another person going into too much detail. It might be a good idea to slow down and give things a better look, discussing once more to come to a new group consensus.

=Consensus with multiple players= This work recommends running games with a single GM and a single player. That, however, doesn't mean you can't play with two or more players. With multiple players, you'll want to take more care when coming to a consensus. If for one person, something is no good, but another person likes it, you should ask whether it's the description of the thing itself that's no good, or if it's fine as long as the person's own character or NPCs aren't involved. If it's the description itself that's bad, everyone should keep in mind not to do such. Otherwise, if only the person doesn't want to get involved... in that case, even if it may cause plot holes, you should take proper care that the respective characters don't get dragged in to such circumstances. In any case, sessions with multiple players can make it unusually difficult to come to a well-balanced consensus. You won't be able to get into as fine of details over what's good and not, and you'll have to limit yourself to a certain extent. The GM may become overwhelmed if every hunter goes after their own NPCs or similar. You should make sure to consider these points, and only take on multiple players if you're confident you can handle it.
