You shouldnt do that, or have thoughts of doing that. You could end up in jail if something happens. I would urge you to at least pay for it. Women are cheap on this website. I can have sex with a woman for £30, for half an hour. We all have fantasies, but both parties must, and have to be in agreement for sex to be safe. I think you should get married. That way you can do all your fantasises with no repercussions.
