Looking for a story

I was hoping someone can help me find a story.

A husband and wife open up a sex shop of sorts, where people can come in and rent a room and do whatever they want, even include the husband, wife, or both. I remember one guy paid to watch people on the CCTV (with consent). At one point a big group comes in to use the sauna or something similar.

Any help would be appreciated!

Hi, were you looking for an existing story that follows that plot, or asking for tips on composing one?

I just realized I'm a year late to your question. 😀
