Skin pigmentation does not wear off or transfer. However when a women is sexually stimulated the ******* flow to the pelvic region increases. Increases ******* flow to the vulva can make them appear darker than when you are not aroused. So getting fucked by a skilled fucker will likely make your pussy lips darker than you are used to if you normally aren't getting well fucked.Is it true if I get fucked enough by BBC my pussy lips will get dark showing how much of a BBC I am becoming?
