Robert Martin's character is dying, and though he doesn't know the whereabouts of his daughter, whom he abandoned as an infant, he's got a bunch of adopted kids that he's not too fond of, and has decided to give them one last chance to inherit (if they can avoid fucking and fighting while at his mansion for the weekend), his fortune. If not, it'll go to one of his trusted servants.
As for the "trusted servants," Dick Nasty's the head butler and Ava Vincent the nurse, and both scheme to screw the kids out of the money by encouraging them to screw each other...and thereby hangs a tale, albeit not an overly interesting one.
Best of show here is Ava, who gets lusty in the opener with Nasty and Don Fernando, though each guy disappears for a portion of their scene "together." Though Don gets blown as Dick pounds Ava's pussy from behind, Dick's not around for Don's between-the-tit action, and Don disappears while Ava camps on Dick's peg, only to return about halfway through Dick's missionary fuck, and both are around to spew on Ava's tits and tummy. Ava also essays some good action in the closing girl/girler with Tawny Roberts, but that's hardly Tawny's best. Look for Roberts' hottest action in a threeway with Cherie and Dino Bravo that includes Cherie's doggie and Tawny's mish, and Tawny getting into the same positions with husband Rick earlier in an outdoor scene.
Tawny, of course, looks great; Ava's nearly at her sexiest, and Cherie is always worth a peep, but nothing about the story here will generate excitement, and the gals can only carry the feature so far.
