A somber-faced, well-proportioned brunette, clad in a black cocktail dress, stockings, and heels, is bound with hands behind her head and one leg behind her back. She writhes silently on a bed, so why gag her?

Actually, we see her in a wide variety of positions, alternately gagged and not gagged, so it's more of a smorgasbord than a progression. She is suspended from the door frame, hogtied on the bed and gagged with gaffer's tape, where her wiggling exposes her nipples. She's bound topless and spreadeagled on the bed, suspended kneeling from the closest bar, and with a leg suspended up the wall. Finally, she's tied to staircase rails. We only hear the occasional whine of protest when she's gagged.

So if you like a variety of positions (though not of restraints or gags – it's all ropes and cloth gags, except for the brief taping), and a passive subject, this will do fine. Incidentally, all but the staircase shot looks like it was done at the local Motel 6 – "This is Tom Bodett, and we'll leave the ropes out for ya."
