Alraune

Once a human male has been chosen as a mate, they will be dragged into a compartment of the Alraune’s body that is closed off from everything else. The compartment is filled entirely with the Alraune’s nectar, and has a tube sticking out from its wall that will grab onto and extract semen from the male’s penis. The nectar in the compartment is breathable by humans, and will cause the male to not have to wait to cum/orgasm again. The male pulled in will be there until he dies. The alraune normally cannot see into or interact with the compartment with her humanoid segment, but can move it into the compartment temporarily to interact with the male if she wants to.
