Zero Two is My Waifu For Laifu
You see, armpits are the one of the lewdest parts of the female body. Sure some people might compare it to feet since they are considered dirty and smelly too, and feet fetish are one of the most common fetishes out there; but inreality armpits are superior since they not only release the hormones and considered and sensetive but also not many girl is fond to show their pits. The hormones makes males think the woman is more atttacitve and since armpits are more hidden and rate to be into them than most other body parts it creates the "ankle" effect. Just like how back then ankles were found attractive because of their rare sight armpits give a similar lewdness feeling too.Thus this is why people from feetgang is the least uncreative and lowlife of the fetishists while armpitgang consists of rarer and more cultured man. Don't get me wrong, feet are very gud.. but armpit is superiority of class.
