I once, years ago, saw a well-made porn video in which the story line was as follows: a couple has just gotten married and is enjoying their honeymoon on a sailboat (sex scene), then some guys in a speedboat come up, shoot at the husband who then falls into the water, and kidnap the wife. They take her to a private island, on which are housed "sex slaves", and add her to the line-up. Then we see various scenes of "unwilling" girls being coerced/gently "forced" into doing sexual things to the guards and the rich couple who own the place.

I haven't seen anything similar since, but perhaps some of you have? I know this category is touchy, because it has to be clear that there is no genuine coercion or force going on, and I assume that's why it's hard to find. Is this type of thing mostly only done in animated porn?
