obsessed with my mom's feet

i've always been into my mom's feet, she always made me rub them and im pretty sure thats what awakened my foot fetish. i never really acted upon it until recently. i've started grabbing her flip flops to sniff and lick them. it feels like i cant stop once i start. i could stay hours sniffing her feet, the scent just triggers something in my brain that makes me unbelievably horny. the toe prints in her flip flops also make me go wild. the thought of me licking the same place she steps on for hours is so hot. i really want to worship her actual feet, i'd probably cum instantly. what should i do?
