I used to be a cuckold to my ex. I have a smaller than average penis. I watched her fuck other guys with big cocks and cleaned up after they were done. If I got to cum I had to eat my own cum as well. At first it was difficult, but I got used to it, watching and being her cleanup cuck.
The truth is she liked big dick and I could not give that to her as I am small compared to what she wanted.
