I like to show my butt crack
I have always been obsessed with intentionally showing my butt crack. I used to moon people every chance I got when I was a teenager and developed a spanking fetish in my 20s.
Sometimes, when I'm working on something and notice that my butt crack is showing for anyone to see, I get excited. Most of my close friends have seen my bare butt at some point, for this reason or that....but mostly because I enjoy showing it off.
I know I'm not alone here because I am a connoisseur of fine exposed butt crack, and there are exhibitions everywhere.
