I'm glad that my English is improving that I didn't read it as you are asking others to beat you. (Something inviting imaginations, nonetheless. Oh, the pic looks lovely, by the way.)Beats me
To get back to the topic, Sandra Day O'Connor became the first female justice of the Supreme Court of the United States in 1981.
To tell you the truth, I didn't know her name until now and I don't memorize such dates... so I just visited Wikipedia page which lists all the notable events happened on September 15 in history, and picked a random one which looks remarkable to me.
I did that because I felt slightly guilty to prolong an offtopic banter in this thread. But it also lessened another kind of guilt somewhat - it's good to be reminded from time to time of what women are like in real world, since in my fantasies, the best thing they can achieve is to be a good slave who can take the whip without screaming too much or learn how to give a good blowjob without using her teeth.
