Lina Mercury, a vision in black lace lingerie and stockings, welcomes her eager applicant, John Adams, for his oral service trial. Adams' eyes widen at the sight of her slim waist and pert ass, clad in a thong that leaves little to the imagination. Mercury commands, "Kneel, slave," as she teases him with her high heels, running them up and down his chest. Adams obeys, and Mercury feeds him her cock, inch by inch, until he's gagging on her deep throat. She slaps his face, leaving red handprints, and forces him to taste her ass, slamming it onto his mouth. Adams struggles, but Mercury's tight pussy and commanding presence keep him in line. Finally, she lets him cum, filling his mouth and ordering him to swallow every last drop.
