Many years ago, I had a girlfriend who had many sexual fantasies. We acted upon both hers and mine. Mine were to be submissive to her wishes, which she took advantage of by having us drive along a beachfront road where hitchhikers were frequent. We would stop and pick up young guys for her to have sex with in the back seat. After an afternoon of many pickups, she and I would go to a secluded place where I would give her oral to her satisfaction. While this was her fantasy, I became quite fond of it and we went together for several years.
