Saw my SIL's cute little bumhole

My SIL and I have this habbit of checking each other's backs for blackheads and pimples.

Well the other day she asks me if I want to check her bum as well. Seeing that she has a really cute round ass I don't hesitate.

Being 'thorough' I spread her ass cheeks apart and boy does she have a cute little hole! I got to touch all around it too.

Haven't gone further but just dying to find out if she will let me check her thighs.
