Exposed armpit folds are basically public vaginas, and when they fully expose their armpits by raising their arms, it's basically spreading their vaginas open and inviting you to sniff and lick, and maybe rub with your cock, but you can't do that without getting slapped and arrested so you're forced to witness the erotic vista of the exposed armpits, and/or smell the pungent aroma behind their back with their arms up as the wind guide their pleasant pheromones to your nose.
