There's a childhood incident which I vividly remember. When I was about 10, I had two good friends, Eric and Dave, who I would play cops and robbers with. That was all pretty tame, but one time, Dave's older brother (who I had a crush on) joined the game and took it further. The three of them tied me up with a jump rope and carried me into a shed (more of a playhouse, really) they had in Eric's backyard. In the shed, they tied me to a chair, gagged me and left me there for a little while before letting me go. For months after that, I tried to get Eric and Dave to repeat the experience, but had no luck. When I was 16, I found a boyfriend I trusted enough to share some of my tamer fantasies with and finally got tied up again.
I have to say, I do wonder now why the brother, who must have been at least 16 or 17, was tying up 10-year-old girls in a shed.
