I can understand. You are able to play both roles. That is pretty impressive. Unfortunately my cock is extremely small and I am not alpha at all so I am very comfortable in a cuckold role but trying to be a bull would not work for me. However as I said, you seem to be able to pull this off so kudos to you !
That is VERY hot ! I am in the same boat except my wife doesn't beg him to stop. It is so humiliating (and exciting) that her bull can make her orgasm 3-4 times in a night and I can never make her orgasm unless I am eating her
