This volume continues the one indoor, one outdoor sex segment formula that seems to have been established for this series.  Greta, the smiling blonde whom we see in those 900 phone line ads in the video trailers, makes a guest appearance in the first segment.  She has her luscious butt worked over by Mike, her partner, who whittles away, using something that looks like a mutant dental plaque remover.  However, Dick and Helen have the benefit of sunshine and the great outdoors, and their scene comes off with a tad more impact.  Helen slips out of her teensy bikini and takes on Mike's manhood which is about the size of a gas hose at a Mobil pump.  Give Helen kudos.  She's a real pro.
