@grevmo There is another one called "Sausage Party" or something like that.
From what I can see, they are often a few porn stars, together with local talent. Some of them seem to be made in England, Florida, Nevada and California. There is also Hustla Ball. England has some kind of "Balls".
I've been disappointed with almost all of them, mainly because of the poor camera work. They don't focus on the hotties enough.
I prefer one-on-one and threesome stuff. Not generally a fan of solo stuff, nor orgies.
There used to be (and might still be) orgies taking place near where I live that are not filmed. I never participated in one, but a friend of mine did. One reason for not participating in these events is that you will encounter people who you do NOT want to encounter for various reasons. You might KNOW them, they might know you, they might have various diseases, they might be creeps, they might be fuglies.
