Not sure how i'm going to turn this into a realisitic story as such but i'll find a way.
Your primary focus seems to be on providing voyeuristic fetish content with incest fetish content being a secondary concern so your story just needs to be in service to that. Working at the Inn solves the problem of getting money and having access to the peeping locations but makes providing the incest content problematic because you have to explain how your family members all decided to book time at the inn where you work.
One possibility is that you just purchased the Inn and are the new owner and have invited your family to stay in the Inn to check it out while you do some work to get it ready for customers. Then perhaps you can create your peep holes yourself or you may discover hidden passages that the previous owner created, so it becomes more about discovering these passages than actually creating peeping holes. Or the previous owner could have installed a hidden camera system where you can watch from a remote location but there are only a few cameras so you have to pick where you want to peep and move the cameras around to different locations or purchase more cameras to cover more areas (or but more cameras to increase coverage with whatever mechanic is used to earn money).
You could also have your extended family on vacation together in a remote location and something happens that they get trapped in the Inn (snowstorm, floods wash out the only road out of the area, etc.). Then you're all trapped at the Inn until whatever condition trapped you there subsides. If you still need a money mechanic your job could be something you could do remotely (being a writer seems popular in games like these) so you just work on your computer and email your work to your boss and money appears in your account.
If you want to go with a more supernatural element in the game you could make it sort of an Evil Dead parody and make the inn more of a large cabin where the family spends their summer. One of the family members finds a book in the basement and reads a passage which summons you (a demon) who gains more power by manipulating the family into taboo sex. you could look to games like Sensual Haunting and Demon on a Starship for inspiration for that.
