One Piece: The Hunt for the Golden Clue

The description is a bit vague, but it seems to be about a group of teenage girls who are kidnapped and forced into sex slavery by an evil organization. They resist at first but soon give in to their captors' demands due to the threat of violence. The girls are subjected to various forms of sexual abuse, including anal sex and double penetration, as well as being used as a means for satisfying the sexual desires of numerous men. However, despite their traumatic circumstances, the girls eventually discover pleasure in their pain and begin to enjoy the depraved acts they are forced to perform.
