Close to being a teacher-student thing but not quite, I'll share this. I was just 20 in 1979 and out traveling the country as a field service tech, installing and servicing machines for a manufacturer (now gone.) I was sent to Waterloo IA and got in late. Just barely made it to the hotel in a raging snowstorm.
Needing a bite to eat, the hotel restaurant bar was the only thing open. I was sitting there at the bar having a beer after eating, only one other guy at the other end. An older woman comes in, sits down next to ME. After talking a bit I find out she's a guidance counselor at the local HS, 34 years old. We had a couple drinks together. I think she may have had a head start before she got there.
I get up to leave and she stayed. For a minute. I walked across the parking lot to my room and a minute later I hear a knock. It's her. She tells me the roads are too dangerous to drive (there was almost 10" out there by this time.) These were the days of actual metal room keys, and the housekeeper had apparently left the key to the room next to mine in my room. I told this woman "this is your lucky day" and took her next door, opened the room and put the key in her hand.
She was not unattractive at all. Quite good looking actually, but at 14 years older than me I had zero interest. A minute later, there's a knock on my door again. It's her...again. I asked her "is something wrong?" She paused a moment then told me outright "I want to f*ck you." She barged in and had her way with me like I never had experienced before. OMG did I learn A LOT that night.
I took off in the morning and checked out before she even woke up, moved to a different hotel on the other side of town. I still wonder if she made it to school on time Tuesday morning.
This stuff used to happen back in the day, the lucky just didn't report it as abuse. It was taken as a glorious gift that it was, shades of "The Graduate." I have to give her credit for hitting the local hotel for a young 'un, though wonder if she ever shopped "at work."
