Dub-Con

Dub-Con = Dubious-Consent

Refers to the presence of borderline non-consensual sexual contact within a story, whether implied or described. May indicate relationships in which characters must agree to engage in sexual contact for outside reasons, are initially hesitant or remain uncomfortable throughout, or in which one or more characters are willing but unable to give complete consent because they are mentally or physically compromised such as being drunk/drugged, ensorcelled, amnesiac, or otherwise not in their right minds. It is a grey area between fully reciprocal intercourse and non-con, but in fandom if not reality is clearly defined from rape. This can frequently be a squick for many people, so should be listed in the author's warnings.
