Damn those are some big loads! My husband hesitates when he can see all the cum...he prefers to lick it out little by little I think.
I think most cuckolds, that serve their wives this way, prefer to have their "pie" "cream filled" instead of "iced" so that they can slowly lick out the combined mixture of the wife's secretions as well as the bull's cum.
That the wife's juices are coating it is why many will also lick and suck the bull's cock clean as well.
