It would depend on what she promised to do. If she was fat with giant titties and a big ass and she said she couldn't get enough forced anal and then forced oral then I would drive pretty far but I wouldn't tell anybody.
If she was a 10 and she said that she didn't really like the taste of cum then I would drive really far and tell everybody.
If she was a 10 and she said that her fantasy was to be raped by a stranger then I would buy a ski mask, rope, a camera, and a plane ticket.
