My step brother has a fetish for feet

my step-brother has always been a pervert. When I was younger, gave me money to show him their tits. It was easy money. But now that I’m an adult, I realized that it is a complete addicted to sex and that, in addition, he has strange fetishes. My feet are one of his many fetishes. Before having sex with him, needs to kiss my feet before. He likes to lick my toes, smell my feet. This makes it excited. Another thing I really like is my ass. Every time that fuck, want to lick the hole in my ass. And I have to say that it does very well. It is a real pleasure to fuck with him. It is always something out of the ordinary. With him I always do new things in sex.
