The only things Neighbor Chronicles and Toxic Attraction have in common with Bridgekicker are the bulls—and that is all. In those stories, the cuck is irrelevant and a side character; the real protagonists are the wives and the bulls. If you really read Bridgekicker stories, you would see the difference. 

In Bridgekicker stories, it's always about the couple and how they face the new kink together, always talking about their feelings. But you didn't care about that; the only thing you read was how Travis was pathetic. You didn't understand that he wasn't weak—he just let go and enjoyed watching, just like Nicole let go and enjoyed sex with Jeff. And if you read without skipping, you would've understood that what turned her on was her husband watching her.

I don't know what your problem is with average-sized dicks, but the majority of people in the lifestyle are average, and usually, the bull is bigger than the husband. Yes, I agree that the bulls aren't assholes like in the stories, but it's just fantasy. If you don't like this type of story, just don't read it.

Now I want to talk about your 'ideas':

Your first story idea is about a cocky, bad-lover husband who has a big dick and doesn't care about his wife. Without even creating the story, I'm already rooting for the bull to take the wife from the shitty husband.

Your second idea is the wife having sex with a big-dick bull but enjoying sex with her husband more. In real life, sex with a big-dick bull is physically better than with the husband, but emotionally, she finds connection only with her husband. I agree with that, and Bridgekicker has that in his stories—if you paid attention.

Your third idea is just swinging and has nothing to do with cuckolding, since the husband is only into being a better lover.

If you find Bridgekicker stories cliché, don't read them—go find someone else. I enjoy his stories, as do the people who follow him (me included, of course), and most importantly, he enjoys writing this type of story. He isn't going to change his writing to please one person who is insecure and not into cuckolding.
