In BDSM, the role Monster refers to non-human, including aliens, science fiction, and supernatural creatures. It is most often used for interspecies mating between a human and sentient (or sometimes not sentient) non-human. These relationships are sometimes imagined as rough and/or dangerous for kink purposes.
A Monster is someone who thrives when able to shed human expectations and explore their darkest fantasies. For some, these fantasies may include elements of fear play, edgeplay, sexualized horror, sadism, struggle play, primality, or simply taboo.
Monster is also a subgenre of erotic horror that involves sexual encounters between humans and monsters. The term is applied to sexual imagery that’s blended with horrific overtones or story elements for the sake of sexual titillation. Monster/human works can also be nonsexual and focus on emotional connection.
