This tape demonstrates why casting is important. You're gonna get the most heat from a scene in which the performers actually want to fuck one another rather than simply doing it because they're paid to do so.
For example, Jewel's a big fan of Nina Hartley's, Nina apparently reciprocates the attraction, and ba-da-bing! Their scene rocks. Nina breaks out the strap-on, bends Jewel over the side of the tub and starts laying some serious rubber pipe. Mark Davis and Chloe apparently always like to fuck one another, and have done so repeatedly, so their scene has genuine heat as well. In this case it comes from a shared history; Mark knows she likes to be choked and dominated (to be fair, a lot of people know this, but he knows it firsthand), so that's what we get.
Granted, there are a couple of scenes that don't really seem to take off as well as the others (the Charlie/Jewel girl/girler and Tabitha Stevens' scene with last-minute substitute Chris Cannon), but overall, these are some strong couplings.
On the technical side, the camerawork is steady, the sound clear and the lighting good. Settings-wise, the scenes are shot in some damned nice houses.
