MANY years ago (more like centuries) I had a crush on a young woman (she was unaware). One day, I was walking toward an area we commonly frequented and heard hysterical laughter. I rounded the corner to find Tracy being held and tickled by three of our mutual friends (all female). One had her arms pinned behind her back and two were tickling her ribs, stomach and underarms.
Tracy (petite, short-haired, shy and fairly flat-chested) was usually the picture of composure for 20 years old. In that moment, she was a mess. She was beet-red, tears spilling down, and her laughter a mixture of uncontrolled belly laughs and screaming.
It was wondrous.
When she saw me, the screaming increased (she was embarrassed). Mercifully, our friends quit tickling her.
Now I had to ask her out. A few days later, I did. I had never had non-con fantasies before, but Tracy's torture was all I could think about!
It wasn't a very good date, but we did have a nice time of snuggling. I gave her a gentle poke in the side (BIG reaction) and reminded her of the non-consensual tickling on the bench outside our hangout. She told me how humiliated she was about being so ticklish, and hoped I would never tickle her (very seriously!). To cap off, she mentioned that her feet were NOT ticklish and that I could tickle them if I liked.
So that was our first and last date, but the merciless torture she received opened a whole world of non-consensual fantasies for me.
