Bound in chains, blonde teen Nikki Anderson is forced to watch as two other slaves, a brunette and a redhead, indulge in a heated foursome. Madame X, their cruel mistress, makes Nikki observe every detail - the brunette's big tits bouncing as she rides cowgirl, the redhead's eager mouth wrapped around a thick cock. Nikki's body responds, her pussy dampening her panties, but Madame X refuses her pleasure. Instead, she makes Nikki taste the cum from her slaves' faces, keeping her in a state of constant, humiliating arousal.
