My Hysterical Valentine and Other Tales (1999)

Five bondage models participate in five vignettes: in the first a lovely brunette ties herself up, but her boyfriend's reaction to her self-bondage isn't what she expected; in the second, a buxom blonde asks a friend to participate in a not-so-innocent bondage game; in the third, a reporter goes undercover to get the world on a criminal mastermind intent on world dominion and is stringently bound and gagged when her cover is blown; in the fourth, a burglar breaks into a home, leaving the lady of the house hogtied and muzzled; when her boyfriend discovers her, he believes she's only playing a kinky game.
