Alright, story time (no pics to contribute, sadly, but NICE thread here):
I was playing once with one of my spanking partners (I'm female, he's male), and, being an old expert, he was explaining to me how the anus was designed for the specific purpose of keeping people humble (read: pure unadulterated humiliation).
During our play time one afternoon, we were fooling around, spanking one another...and I swear, he started to spread my asscheeks to expose my hole...I got hit there, lightly, a few times, and I can honestly saw that it was one of the most embarrassing moments of my existence.
However, he, also, describes the female anus as "beautiful." I just wanted to sink into the floor at the time, haha...But I made him suffer a bit later.
Thanks for bringing back the memory, though...
