I can imagine. I remember the same thing my wife said the first time I started sharing with my black friends. She complained that it was as if she were sore. to make you understand she said it was like an anaesthetic. this is because she was fucked for a long time, not the usual 5/6 minutes, then the cock was big and she was slammed hard with powerful blows. I remember very well how swollen her pussy was. wonderful very exciting.
Several women have told me ‘never again’ after trying bbc, the most cited reason is the pain they endured when the bbc hits their cervix repeatedly during sex.
