From a FB to a BF in the blink of an eye

We spent a lot of time horizontal. I knew what he liked me do, how he wanted me to do it and where he wanted me to do it. He was a great FB (fuck buddy), there were no complications, no expectations, just good fucking. Then things started to change.

One evening he came over earlier than usual and we talked. We sat in the living room and had a conversation. I was freaking out on the inside! I didn't wanna talk. I knew where that could lead
--> more talking
--> getting to know each other
--> "liking" each other
--> ending with us in a relationship.
I wasn't having it. All I wanted was a steady FB...was that too fucking much to ask!!!!

Needless to say, we kept talking and one night as we humped along, he said it, "yeah baby, this is MY pussy," and he said it over and over. Kiss my ass.

So as not spoil the mood, I asked, "who's dick is it?" and without hesitating, he replied, "its YOUR dick baby." Of course it is.

Shit, once folks start naming and claiming pussy/dick, its all over.

So, during our post-climax pillow talk, my worst fears were realized:

Me.: so we're namin' & claimin' things now?"
Him: yeah
Me: really, so we rollin' like that now? we're gonna do this?
Him: yeah we are

How the hell did that happen? Where had I been during the last four months?

He moved from an FB to a BF and I have no idea how he did it.
