For her 18th birthday, Nikki Valentine gets $4000 from her "daddy."  I guess this means she's got enough cash now to make an adult video.  Well, second best thing, dad Mick Egan also gives her a gold care so she can go rent some sexy tapes and knock her socks off.  "Mom" (Lady Samantha) listens in to all this and wants some of the action.  She gets sex, I'll take the gold card.  Nikki needs help with her video selections, goes to a recognized expert in the field, Jeannie Pepper for advice and guess what happens?  Nikki watches Frank James on her TV monitor and becomes a certifiable sex slut.  That would do it for me, too.  As a special extra birthday bonus, she gets nailed by Sean Michael, and they all live happily ever after or something like that.
