My aunt wants me to work for her, but to keep it secret

I (24M) graduated college but still can’t find a job in my field (management), and instead work different jobs. I currently live with my aunt (51F) and split the bills with her. She’s offered me to be her manager for a job I had no idea she has until now.

She revealed to me that she makes her own x-rated content, and it would benefit the two of us for me to manage her. I would get in on good money, and she would have someone to manage her time, collabs, and setups. I’m the only person she’s told about it, and she said she wants it to stay that way since she doesn’t show her full face yet on camera.

I said yes, because I really do need to make more money. I really don’t like the jobs I work right now. I’d like some advice on how I can stay professional though being a manager for my aunt doing THIS specific job, as I need to be secretive about it for the time being.
