I experience something really unique with my bbc lover, and I'm curious if any other ladies experience it too, or know what it may be. When we are together, he can't go all the way inside me at first, he keeps hitting "that spot" where he can't go any deeper. He just keeps up a steady push. It doesn't hurt, it's just a steady pressure. Then, I feel something deep inside of me kind of snap, relax, and open up. Then he goes all the way inside of means I go into orbit! The most intense, strongest, and longest orgasm I have ever experienced. He just stays deep inside of me and I orgasm over and over. I love it, but I'm not sure what is happening. My hubby thinks what I am experiencing is my cervix opening and him penetrating it. I'm not sure that is possible, but maybe some of you can tell me what it is. I do experience some light spotting the next day after we play.
