Not the game i thought it was then, if they are li you might want to add the ntr tag. If they are not, people who like harem, will probably not play anyway, if you show other people having sex, orcs raping random chicks.
Those are optional. A simple example: if you stumble upon a pack of orcs that captured a girl, you can fight them off, you can spy on what they are doing (and hence watch them having sex) or you can leave.
