When I was a kid, I read a Dear Abby letter about a parent that caught her son playing doctor at a family reunion with a cousin.
She painted his penis with a red lipstick and made him sit out in front of the others to shame him.
It sounds awful and traumatic, but at the time it was shockingly arousing.
It began to shape some of my own tastes. I had a babysitter much like the one in "Keeping the babysitter in line".
(not quite as cool, but looked like her)
She asked me to show her my cock, and she wanted to practice sucking it. She also showed me her pussy - although it was the 1980s, so all I saw was thick black, sweaty hair.
In retrospect, she was an "older girl" who blew my mind.
In reality, she was just a silly teenager, only a year or two older than me with little sexual experience and she wanted to practice in a safe way before she got around the older boy that she actually liked.
The other day I was looking at Youtube, and I saw someone explain why many enjoy humiliation.

(if femdom freaks you out, don't watch, but this isn't really about femdom. It's just an explanation of why shame/humiliation can work as a fetish).
She explains the power shift and behavior causes brain activity that can release endorphins, when giving/receiving or just reading about it. You don't have to be the recipient of it to get turned on by it.
The part that rings true is the increased brain activity and that goes along with reading a story instead of just watching a video. I can read 50 chapters and enjoy it. I get bored in a video and fast forward after 2 minutes even if its about the same things.
