Fingering my ass and smelling my fingers 2

I am lying down on the couch with short leggings while watching TV. I put my hands inside my leggings to scratch my ass then I smell my fingers. Sometimes I fart on my fingers to cup some farts and then smell my fingers. After 5 mins I take off my short leggings then I finger deeply my asshole fully nude, then I smell my fingers. I let some farts out while I am fingering my tight ass too.
