So that is 11,250 couples having sex today, excluding couples where one partner or the other is sterile. Excluding all gay or lesbian couples, oral or...anal sex acts, bestiality or other activities where there is no possibility of pregnancy. That's couples having sex today, where the result WILL be a child.What is the percentage of the population that uses birth control? 10%? 90%?

I took a deep breath and closed my eyes and half way though my sniff I felt her ass hit my face and my nose buried in her crack!! I quickly turned around just as she turned around and excused herself, saying she was sorry! She didn't. Just looking at her made my cock even harder and when I laid down next to her she remarked on its exceptional thickness. (Although it is only 6 inches long, it is as fat as a sauce bottle. Some would say it is abnormal but grannies love it because it really fills up their slack sloppy fuck holes. And as it is nearly as big when slack, it attracts their eyes when I go commando in tight trousers when walk round the supermarket)I began kissing and necking with her as I skilfully felt all over her. Action movies was my obvious choice and her was Romantic movies. So we decided on P.S. I Love You movie. As the movie. After only few minutes of watching she asked shall we have a drink I have a scotch bottle stored up. I said why not its a nice idea. We started drinking and watching the movie.
