My wife doesn't have a bull or a boyfriend even but most of the time I wish she did. I'd love to start off by helping her suck him, her teaching me how to suck cock properly and how he likes it sucked. Then, I suck him and get him hard and ready to fuck her while they make out and cuddle. Next, I get to sit and watch while she gets fucked the way she likes it and when they're done I first suck and clean him, then I clean her. So yeah, I'd do it for her if she had one and was into it but I'll probably never live that out except in my mind, sadly.
