The premise

From what I know this is actually a real thing, but it's a korean custom in which little girls were only fed peaches and then rich noble men would lick their sweat, penetrative sex with them was forbidden and they were really short lived because of their inadequate diet. I don't really think it's any less pedophilic just because no penetration was happening. I am also slightly unsure if my memory of it being a korean thing is acurate, I found out about this a looong time ago and I'm not really sure how to search for it.
