I got you. This is a while back and from .29 but was put together by another user. This is the best Walkthrough (updated through .29) I've seen.
There is one modification to this that I'd recommend. I just horked through a play of the Lizaveta character, because 2010-era Lisa Ann was a smoke bomb and all her scenes appear to be of that vintage, and so it brings me a lot of ------ I'm gonna go with "happiness" to play her story.
When you start on her seduction (I think both the love and blackmail paths start out this way), you can go to her house on the weekends to clean her pool (which, at this stage, is
not a euphemism, like "Hey big boy, you wanna
clean my pool" *wink*elbow nudge*). Once you get to the point where her husband is out of the picture, if you have decided on the Love path she will proceed to ask favors of you during the week. Either pick up groceries at the mall store (1800hr), or ride with her right then and there in the afternoon when you ask if she needs anything, or to go clean her pool. None of the walkthroughs I've seen specify that to do this pool cleaning you go to her house in the Valley at 1800hr on that day, and there will be an option to clean her pool. You progress through this 6 or 7 times, during which she visits you and gradually reveals more of her figure to you through the cunning abandonment of a towel. The need to go to the front of her house at 1800hr had me confused for a while.
I think a few comments in the thread have pointed that out before, but I'm repeating it here to bump the information.
