That special cock you sucked

Over the years I have sucked off thousands of cocks and now they mostly blend into one beautiful wet collage. However, a sissy never forgets her first cock. (My Grandfather)It was pretty average length but thicker than normal. It would be forgettable except it was my first and started me down the road to a lifetime on my knees. I can also vividly picture the three REALLY BIG cocks I sucked off - two black and one white.

What really stands out in my memory are experiences with real men who were especially dominant and totally used, humiliated, and degraded me.
