Pretty sure you have hit the nail on the head.
Just a side thought. The last part of that statement makes it sound more like prostitution than being just a cam girl. They're paying her to fuck her...on cam. Of course Jack and Jill do live in Vegas, and it's legal in Nevada. But damn. Might just be how I read it, but it hit me as, well, prostitution.
Also, at least to me, it seemed like she was a bit of a fall back for Jack and Jill. If they didn't have a performer booked for a particular day, they could just get her on the stream because she lived in their house. Personally, I wouldn't have ever put myself in such a position. Lilly would've been better off just having her own place and just joining in an occasional stream with a set price depending on what would be done in the stream. Otherwise she would have been better off just streaming by herself.
