That entrance hides a dark tight and unimagined pleasure. I like to introduce myself slowly back there, feeling like I make my way in my sphincters, then vibrate from within. This made me all wet, it is inevitable moaning and panting, so I don't use to giving me that pleasure very often.
It is delightful touch from behind, and I like to see as I do, that shape of heart that has invited slapped my ass ... that sound makes me crazy, and still more strongly to orgasm.
Masturbating my black little hole is one of those exquisite pleasures I usually do, as a naughty bad girl I am.
