It's not exactly that clear cut with the categories I don't think. I think most scenes would be accessible regardless of dom/sub preference, we would only be gating a few specific paths not a quarter of the game each. If I may ask, what sort of choices would you like to be seeing in the nsfw scenes? If you think what we have so far has been limited I'd love to expand the possibilities.
So in terms of group encounters; the one scene that does exist is if you go clubbing with Gia you can pick up two guys. That's a one off event. We don't have any actual committed polyamorous relationships yet (we don't have any commited monogamous relationhips yet either) but there are plans to develop some relationships that way.
