I Got Fucked By My Girlfriends Bull

So as the title made clear, I am a cuck! I’ve watched my girlfriend get fucked by tons and tons of men and we both love it. My girlfriend is a size queen and I have a 4 inch dick and have a fetish of having my dick made fun of and called small. In general I like to be dominated in the bedroom by my girlfriend, whether she is telling me my dick is small or I can’t fuck her right, me watching her get fucked by another man or telling me about it, or even as far as me becoming the bitch and getting pegged by her which is some of our best sex in my opinion. Obviously with a fetish like mine, I have been embarrassed in the bedroom a lot. Whether it’s a bull talking shit to me while my girlfriend cums on their dick, or even as far as listening to my girlfriend tell her ex boyfriend that he still owns her pussy while he fucked her brains out in front of me (one of my favorite cuck memories). But what happened recently to me was a new sexual high for me, but also has me conflicted on what to do. My girlfriend has found a great bull that she has consistently fucked twice a week for 6 months, I’ve never seen her cum as often and fast with anyone else. He has this perfect 7 inch dick and the perfect amount of girth. Not to big, not to small. As you can tell, I really enjoy looking at his cock. I have a dildo that I play with abd get pegged with that is almost the exact same look and size as his cock. My girlfriend will role play as him fucking me and knows I cum thinking about his cock. But, she hasn’t liked the idea of me taking it any further then a fantasy. She is very protective and insecure about me being shared with anyone else thinking I will like it more. So I never brought it up. But fast forward to last weekend, it was Friday night and her bull, we’ll call him Kevin came over to fuck her before going on a 2 week vacation. Kevin has a drive here that’s over an hour, he does it because the sex is so good. But on this Friday, my wife got stuck at a work dinner that would not end, it was 10 pm and Kevin said he had to go home to get some sleep before an early plane ride in the morning. We had both been drinking and were both already naked, so I said I felt bad he drove all the way out here for nothing and offered to suck his dick if he wouldn’t say anything about it. He said hell yeah and I wasted no time. I did everything I know I liked during a blowjob and he was loving it, sucking the dick of the guy who dominated my wife in the bedroom felt right, I was his bitch already and we both knew it, this just felt like we were making it permanent. But in the back of my head I knew I wanted to fully own me. I wanted him to breed me. I popped my mouth off his dick and asked if he would fuck me and keep that a secret too. He didn’t answer, he got up and spun me around and put me on all 4’s. Just like that I was living out my fantasy and it was even better then I imagined. I came 3 times and he bread me. I thanked him 50 times and said that was the best sex of my life. My wife still doesn’t know and I feel guilty, I’m not sure how to bring it up at this point.
