Concept: Maybe forced partners requesting things in a much more preferable way for the player? I.E. "Please...not there" referencing stopping a action or replacing it with another (vaginal versus anal for example)? Or a button to turn off requests from different forms of partners? Raising the enjoyability for the slave through requests helps make it easier to gain obedience and loyalty through sexual means, but I can see how that would be a bit odd for some situations in game.
