Tiffany Watson actually asks and answers that question in between the first and second scenes of this, her star showcase, which includes a couple of firsts (G/G orgy, DP) and, as the title indicates, features a copious amount of that inexplicable fetish, squirting (which, to be fair, I'm into --even if I can't explain it).
For the most part, I've stuck to plot-oriented features. With this, I've decided to intentionally branch out a little into gonzo stuff, but mainly when it features performers or particular categories I like. Taste is, after all, the name of the game. So how is it watching an all-sex feature from start to finish? A little tiresome, to be honest. The only thing that really saves it from slipping into complete monotony is the occasional "Wait, what did they just say?" pornspeak.
A few final notes/criticisms:
I understand that modern sexual ethics is completely oriented around the idea of consent, but actually hearing performers invoke that during a sexual performance is odd. And then on the less serious side, Whitney Wright turned out to be less attractive in full HD than I had previously thought after seeing her in Sugar & Spice. Towards the end of the G/G orgy in which she was a participant, you got some closeups of her face and it appeared that she needs some dental work. There were also some suspicious red marks on the lower part of her face that were either acne or, God forbid, herpes. And then on the more subjective side, Tiffany Watson gave off major White Trash energy.
So, if you're into all-sex/gonzo/etc., I suppose this would be worth your time. I normally wouldn't give this more than several minutes for, you know, and I certainly won't be putting this DVD in again any time soon. Aside from, umm, research, the ideal situation for this is probably as background for some kind of naughty party.
