[F4A] Casual Sex within a group

I'd like to find someone creative to help come up with a roleplay that we like. I'd like to focus on the idea of a shared living space between a medium to large group of people. Basically, the dynamic I'd want to capture is that all the members of the group fuck each other, whether for fun or perhaps stress relief. Elements of free use, bored and ignored, casual sex and voyeurism are all stuff I have involved. Some vague ideas I have are:
- A space station or smaller space ship crew
- A smaller co-ed college dorm or apartment complex
- A military unit or live-in factory crew (could be modern or sci-fi)
- A couple families in a duplex (some sneaking around also)
- A travelling performance group or co-ed sports team
- And any other ideas that you have!

I'd love to integrate any kinks of fetishes you fight have, while still focusing on the kinks I mentioned above!

Thanks, hope to hear from you
