I've read countless stories on this site of Kaley breast smothering her way to victory. If there were only a couple of stories involving her winning via breast smother that would be one thing, but there is such a high volume of stories that I'm surprised that this would even be debated.
And if it would be that much of a stretch to suspend one's disbelief, then any match that ends with a facesit would be a stretch. The person being sat on could just bite their opponent's crotch. Any fight where the loser is forced to kiss the winner's ass, foot, etc wouldnt be realistic because they would just leave without doing so. Also, any match involving someone getting thrown into the ropes and the person getting thrown runs, rebounds off the ropes, and runs back toward their opponent, would be unbelievable as well. I'm not one to think so critically about the intricacies involved in a breast smother, especially when it revolves around a fantasy.
I'm not one to question every minute detail of an action movie either. Not everything has to make sense to me, because it's a movie. People don't walk away from explosions in slow motion. Movies are fake, pro wrestling is fake and fantasy celebrity fighting is fake. This is simply a fantasy. I read and write stories on this site in order to suspend reality. If you are this critical over the details of every story, I don't see how reading on this site would be enjoyable for you. This type of critical analysis would seriously suck the fun out of anything I write about.
But, it seems as if you may enjoy critically analyzing fantasy fights between celebrities and, if that's the case, more power to you! I'm sure there are many others that share your eye for detail on here. If you're looking for super realism, my polls/stories probably aren't for you, and that's okay with me. I'm just here to have nonsensical fun and, honestly, discussing this -- the qualifying factors of a proper breast smother -- in so much detail, kinda drains the fun out of it for me.
