Probably not in the usual definition of this. I am only interested in doing this with my wife after she has been with Lovers. I think most definitions would siggest an interest in cum from any source, like my wife was when she was in her 3 year BBC exclusive period. By the time it ended, the only thing that mattered to her was that the guys were Black and she would have sex with them. That is my concept of a "cum dump".
But, I imagine in terms of AMOUNT of cum I have eaten over the years as a result of her affairs, I probably meet that definition. Her affair with her Boss/Lover lasted 11 years, and they were together 2-3 nights a week and many weekends also. And the traveled for business together during that time too. I cleaned her up every time she came home, wherther it was an evening in town with him, or after a week long business trip.
Never had any urge to ingest cum in any other manner tho. Just from my wifes cunt. CW
