In a dungeon lit by harsh, industrial lights, Lita Mackenzie, a submissive slut, is bound to a sex machine by Brutal Master. He teases her with the machine's throbbing phallus, not allowing her to climax, as she's gagged and blindfolded. Electricity zaps her body, heightening her senses, as she's made to orgasm on command, only to have the pleasure denied repeatedly. Lita is humiliated, her pussy dripping with lust and shame.
