We got some interesting suggestions actually for the cafe on the patreon, some went too far for this part of the story, such as gloryhole content (something we very much want to explore later...) but there was some intesting stuff.
In terms of Olivia, I personally did pitch an idea to Abyss the other day

we'll see what we can do with that, and in terms of the swingers of course we want to get them involved too!
It's always a question of what fits the chapter narratively and what we can stuff in there. While feedback on chapter 5 was overall very positive there were some complaints about how all over the place the scenes felt, because we stuffed so much stuff in there. So for this chapter we're trying to focus in on fewer, narratively focused sexual scenes that are very lengthy.
That being said we always read any and all ideas and are happy to receive them, whether or not we integrate them will depend on many factors.
