My first submissive act was non-sexual. It was around the time of my graduation, I was full of confidence, and still held by my principle of 'no man is going to boss me'.
It was at a summer ball, and this man who I only vaguely knew LEAD me in dance after dance. As in he REALLY lead me, his eyes and hands told me unquestioningly exactly where he wanted me, and how he wanted me to move. And for the first time I submissively obeyed.
What happened next.......well that is a story the two of us are still writing.
