I like washing my feet
Why do you wash your feet?
They're smooth and I like the smell after washing them.
It's expected that you practice good hygiene and washing your feet regularly is part of that practice and is important. It's understandable that you enjoy the smell of the fragrance of soap as many are formulated to be pleasing to smell.
I'm going to wash my feet at work and hide it haha.
I don't think washing your feet at work is a good idea. Your coworkers and your boss might not appreciate it very much. You should leave the washing to at home.
