Fantasies are strange, huh? Where do these things come from?
Mine, or at least one of them, has been persistent with me since I was much younger. OK, since I first began hobbying. Simply this: getting picked up in a bar by a provider who is angry enough about something to be a little forceful and dom. Not cuffs and ropes angry, just aggressive. And I like frank, open dirty talk about the activities, not the seductive pretend stuff!
And if it was with Mary Beth or Ginger, that's a bonus. If it was both, that's nirvana.
Someday...
