My wife has always insisted that I suck her Bull's cock and swallow his cum. We started this with our first bull in college. It makes for a stronger three-way bond. She and I also agree that it is the ultimate way for me to honor and show respect for her bull.
I'm bisexual and I have enjoyed sucking cock and swallowing cum from a very young age. Even my own cum. So, I love doing this and I feel very lucky to have a wife that enjoys me doing it, lol.
