Body parts are one of the easiest things to get addicted to.
There’s so much things to get your mind to focus on and one of the most important tool in your brain box: smell.
It works with almost any body parts (feet fetish anyone?) the smell alone can get you hard or wet.
And the best part is? You don’t even need a partner for this.
But then again, would you be reading this if you needed anything else but porn in your life?
