[F4A] Let's chat about my super casual free use world

I often fantasize about a world where people have incredibly casual, almost completely ignored free use sex with each other. I'll fantasize that someone gets a ride to work in the morning and casually blows the driver while he talks about work or just doesn't say anything, only having a stifled, melting orgasm and then they go back to normal.

Just every day situations where someone walks up, uses someone else, and neither of them acknowledge it, but still get pleasure from it against their will. Relationships, conversation, all of it just goes on like nothing is happening.

If you want to chat about this world, let me know!! Any partners are welcome as long as it interests you and you can hold up a conversation.
