That is a great beginning and end to any romance story. When your in a relationship you fill in the rest every day of your life. The rest of the story could be anything and well I like it.
Dang you know I've been there, not with a her getting out of the truck and saying that, but well I've been there.
So here you go, what happens next, she he in my case of course gets out of the truck says I love you and walks away, I sits there for a second flustered because those three little words send up a storm of emotions. The person getting out of the truck had been a friends with benefits, well actually more of a roommate with benefits in my case. Perhaps the feeling is shared, perhaps it isn't. In my case it was and it led to a rather interesting 6 months, though it could easily be not shared and then the frantic attempt to pull away without losing the sex, or simply going along with,
Of course in the going along with it can go two ways, perhaps the feelings do become shared eventually, or not.
