The story I tell normies is the one I'll write in the True Story Anthology someday called "Bronco Roping," about a high school girlfriend who couldn't hold still for oral sex. But the real origin story started way earlier, and is the reason why as a tender young HS senior I was already good enough with rope to tie Lori down so well.
One evening in 1970, when I was five, my regular babysitter Kathy invited her girlfriend Barbara over. Later that evening I was playing in the back of the house as the two girls watched TV in the living room. Suddenly, over the drone of the TV, I heard shouting followed by the sounds of a struggle. I ran out to see what was happening.
Something had spun the girls into an argument, which became a fight, which finally became a wrestling match, and Kathy was just getting pinned as I stepped into the room. My sitter was thrashing angrily and spitting venom as Barbara rolled over on top of her, straddling her thighs and pinioning her wrists.
Immediately they both looked up and saw me. Red-faced, Kathy yelled "Get back to your room!" spinning me on my heel to obey. To my five-year-old self, Kathy at 14 or so was pretty stern and forbidding.
"Wait, hold on!" said Barbara, settling into her pin. I turned around, and she smiled at me. "Come back here and tickle her feet."
Kathy bucked. "DON'T YOU DARE!" she screamed. "Get back to your room RIGHT NOW!"
Long story short, and no surprise, Barbara's persuasion eventually won out over Kathy's ultimatums. I distinctly remember how angry Kathy was, and how her threats at first escalated but then turned to begging and screaming as I found a place to sit on the floor behind Barbara, near my sitter's bare feet. For what it's worth, Barbara's feet were right there as well, and she was wearing nylons.
But it was Kathy I'd been asked to tickle, and so tickle her I did. She went apoplectic, and Barbara egged me on to keep it up no matter how frantic she became. You see, Barbara's goal was to force Kathy to "take it back," whatever it was, and I was just a convenient torturer in her plan.
The biggest impressions I took away were how easily I was controlling this major authority figure in my life and how hard she tried to resist laughing but failed, despite being absolutely furious. Kathy finally gave in full to belly laughing while Barbara laughed along with her at the ridiculousness of it all. By the time Kathy broke down and took back whatever she'd said, things had pretty much deescalated.
After she'd given in, though, Kathy had a final parting shot. "Now tickle her!" she yelled to me as things wound down, so I finally got a quick shot at Barbara's feet too, causing her to jump and roll off.
That night tickling became my thing, and through much brainstorming on how I could do it some more, I soon became deeply interested in tying people up. By age ten or so I was pretty good, and by high school, I had a reputation for playful kink.
Don't even get me started about that 1979 McDonald's commercial though. If I'd had any hope of turning back to normalcy, that fully torpedoed it.
