I think from a woman's point of view it would have to be two men at the same time. Both men doing nothing but trying to please me at the same time and then seperate times. I have done the two women for hubby and he loved it.
I once had the fantasy about going to a bar and having sex there with other people watching. I told hubby about it and we did it soon after. I loved it. The only thing about making your fantasies come true though, is that you then have to find something new to fantasize about. I think that I would rather keep the two men fantasy in my head and not bring it to reality, makes for wonderful masturbation sessions....
