They love being licked, touched, pinched, or pulled; they are the sensitive nipple queens who can climax just from that. It is a well-known fact that the human brain releases the pleasure substance dopamine when it feels good. Their nipples, or rather, they, clearly remember that feeling of pleasure. That's why their bodies react sensitively, making their vaginas wet and sticky.
