Incest

Any sexual interactions between members of one's immediate family and those who are close enough to prevent marriage are referred to as incest. What might be deemed incest may vary from one place to another due to variations in state and provincial marriage laws.

Although significantly fewer people actually practice incest, fantasies about it are widespread. This fantasy involves breaching taboo, as do most fantasies.

More About Incest

In order for a relationship to be considered incestuous, the parties involved must be sufficiently close that both law and custom prohibit marriage. In certain places, this covers cousins, as we are all members of the immediate family. First-cousin marriages are legal in some areas, although first-cousin marriages with second cousins are usually regarded as abusive.
