When incest is made evident within the post itself through dialogue or narration rather than just through the description or outside character knowledge.

Generally this is established through a character engaged in a romantic or sexual act calling their partner by a familial term, or by siblings referring to "mom and dad" being absent or catching them.

Exceptions:

• "mommy" or "daddy" with no other indication (mommy kink and daddy kink)
• "bro" between male characters (though "little bro" and "big bro" both work, as does the full "brother")
• "brother" for monks, and "sister" or "mother" for nuns — these are all common titles and do not indicate any relation
