I don't know who enjoys me being fucked in the ass by a bull more, the bull himself or my wife, watching, coaching, and assisting him. I have not ever been fucked where a bull has not emptied a large load of his cum deep inside my ass or where the bull did not vocally and physically express enjoyment while in the act.
My wife tells me to get on all fours, doggy style, and she will then spread my cheeks and tell her bull how tight my ass is and seductively ask if he enjoys very tight holes and if he wants to fuck me for her. She is the one normally who will apply some lube and push her finger inside me a few times to open me up. She laughs when I squirm, saying if I think her finger is uncomfortable, I will love what she is going to put inside me next.
She will kiss her bull's cock and tell him to give it to me hard and to fill me up with his hot man's cum. Then, she is the one who will begin to guide him toward and eventually into my tight hole. Sometimes, she pauses before pushing him inside to take a picture and photograph him entering me.
Once a bull has fucked my ass, there is a complete change in the cuck-bull relationship. I naturally become submissive toward him even when in non-sexual situations.
