Camgirl problem?

Hey guys! I have this "job" (if you can call it that) which causes me to make anywhere between ... Well a shit ton of money. A lot of my income comes in the form of Amazon gift cards, which is cool because Amazon is like a giant store for everything. But I still live at home so the problem is; how do I explain to my father, who believes I don't have a job, about all the money I'm making? I'm sure he wouldn't be too proud if he found out I was basically a cam girl. He has access to my bank account and has once questioned the flux in my savings to which I told him I made a high price bet with one of my more wealthy friends... But that was a while ago. I'm constantly receiving things from Amazon and I've basically refurnished the entire house with things I like from Amazon 😅 my dad comes home from his 3 1/2 week long trip and I know I need to tell him SOMETHING about where all the money is coming from. What would you do?
