Saggy Sweatpants Ass Crack Scratching Smelling

I'm relaxing on my bed, wearing a crop top and sweatpants. As I'm moving around my pants sag lower and lower, revealing my butt crack. I also have a stubborn itch so keep scratching my asshole & crack, but making the most of it by smelling my fingers after scratching. Filmed in a voyeur/ ignore style so no talking/ camera interaction.
