Well, let's just say ballbusting isn't exactly my cup of tea but as long as there is a whole lot of people on the earth there will be a whole lot of weird fetishes, and there will be a whole lot of people to experience them. See, on a website such as BallBustingTube.com, you will be able to find a whole lot of videos such as these.
Honestly, I don't get fetishes like this, but it's probably just me. I assume the point of these videos is to emasculate the men in them, and then I guess the people who watch these videos will relate to them because for some reason they want to be emasculated as well. I don't know why they are like this, but they simply are the way they are so let's leave those people be, and let them enjoy their porn, god damn.
