You're Taking Feet Pics?! At Least Let Me Help

I knew things had been difficult since my stepdad lost his job, but I didn't know they were that bad. I caught him trying to sell feet pics online! I didn't want to judge him, so instead, I offered to help. I'm a really good photographer anyway. The only thing that made everything weird was that he got hard when I took the pics. He tried to explain that it's because feet are... his thing. Why did I find that hot? Knowing his kink was turning me on. Next thing I know, my feet were rubbing his cock, he was moaning, and I didn't want to stop. I guess feet can be our thing.
