Offers of a deal insincerely made. The evil lord (or gang boss) has her father (mother, brother, boyfriend) in his power in a dungeon or a cellar and he’ll release him if she lets herself be fucked. He fucks her and kills his prisoner. The evil lord/barbarian chief threatens to destroy the nunnery/shrine and kill or enslave all the nuns/priestesses, but will spare them if one beautiful young nun/priestess who has reached a place he can’t storm surrenders herself to him. He rapes her and ravages the nunnery/shrine.
Or an undercover cop girl. She’s playing the part of a minor gang member who is not for taking at will (since she doesn’t at all want to be taken at will). The gang boss finds out she’s a cop, but he pretends he doesn’t know. He offers her a key position in the gang if he can make love to her. She hates the idea, but a career triumph and the destruction of the gang are the prizes. She agrees. Gets fucked, then tortured for information, then beheaded or sold out of the country for a slave. A variant would be a reporter girl who rightly suspects big-time corruption or other criminality from a powerful public or business figure. He knows who she is, but makes sexual approaches as if he doesn’t know. Fuck her, get rid of her. Of course, in most of these situations, the guy could just rape her anyway without the pretence - but the little play appeals to his twisted semse of humour.
