In the grand estate, Sophie, the maid, is ordered to clean the young mistress' room. Dressed in her crisp, black and white uniform, she can't help but feel a spark of desire for the young woman's body. As she dusts, she notices a lacy lingerie left on the bed, her imagination running wild with visions of the mistress in it. Sophie's hands wander, touching her own body, feeling the heat between her legs. She can't resist any longer, slipping off her uniform and masturbating, fantasizing about the mistress' touch.
