Devadasi

We still don't know.

Historians agree that it comes from India, from the Devadasi community, which were women who instead of marrying men, they married a certain deity, and they performed certain rituals, and they were dancers.

And in some parts of India, they also were, uh, almost like th- they were alm- they were giving sexual favors to other devotes of that temple, right? And apparently, throughout their learnings, they would learn how to control their bodies in a certain way, and they would learn how to control their pelvic floor muscles or their vaginal muscles in a very specific way to provide insane levels of pleasure.

So these women were allegedly able to milk and twist and squeeze and do all of these crazy skills with their vaginal muscles.
