The Beggar is an NPC in BLACKSOULS 2 you can find at a specific part of Lutwidge Town. The Beggar looks like just any other Beggar enemy in the game. When you find her she will be having intercourse with one of the Gentlemen.
After you kill that Gentleman, the Beggar will still be on the ground and you have the choice to either kill her or rape her. Choosing the latter option will activate an NSFW scene with her, which will send her to the dungeon.
Killing the Beggar will make her drop a Girl’s Photo.
