Free boobs

You want to see how little it takes to make you cum, so you write

"Old Rule: Clothing covering the boobs is used only in very cold weather like gloves"
"Old Rule: Fondling and pinching a woman's boobs is considered a polite greeting"

Immediately you notice that the barista is not wearing a top anymore, on the other hand she has a chain clipped to both of her nipples. You apparently opted for a more conservative option: a shirt with a deep cleavage that leaves your nipples visible, but still covers your tummy.

You try to leverage this new social norms to orgasm by greeting a few strangers in the bar: the first one strongly pinches both your nipples, while the other one cupped and fondled your breast for a few seconds. Although pleasurable you quickly realize that this will not make you cum: you could not have a nipple orgasm before and the rules did not change that.
