What causes darks spots on butt cheeks? I've seen them only on the 50+ AMP women.
They seem like bruises and feel normal, not scaly. And the women don't seem to feel pain if you touch them.
For an example, see minute 38 of this documentary (Asian wives showing panties). https://www.tnaflix.com/japanese-por...1/video4815894
I haven't watched the entire video. So don't spoil it for me please.
