Is it normal i sniff my stepmothers feet while she sleeps.

My Latina Stepmother has sz. 5 feet & always sleeps barefoot. I saw that her Feet & Toes were visible & I got hard as a rock. Her Toes were Pink & irresistible. I got my Dick out & got close to her Soles & inhaled the Mouthwatering Smell of Stepmoms Feet. I fantasized about doing this for years & it finally happened. I took videos & photos of her Feet & now I have my Stepmoms Feet as every background/wallpaper. Last night she slept barefoot but this time I wanted more. I got completely naked & got closer to her Feet & sniffed them, the smell sending chills down my spine. I let my load off on her Small Perfect Feet & she doesn't know anything nor does she know that her own Stepson wants to do nasty things to her.
