A curious, bi-curious beauty finds herself in a seedy gloryhole, driven by her dominant mistress to service anonymous cocks. She hesitates, then eagerly takes the first black shaft, slurping and gagging on its length. One by one, she pleasures strangers, her humiliation growing as she's used for their pleasure. Her mistress watches, taunting her with a strap-on, ready to take her place once the sluts have had their fill.
