They reached a lull in the evening, and the buyer walked Anna towards the back of the venue, pushing open a set of doors and entering the quieter corridors behind and around the building. The sounds of the party receded and were taken over by only the sound of Anna's heels clicking against the hard floor. "Where are we going?" she asked.
"Here," he replied, turning a corner and stopping at a table. It was one of many random pieces of easily moved furniture that could be used for the different kinds of events the venue hosted. The buyer turned Anna to face him, her ass pressed against the corner of the table. "Pull your skirt up."
Anna only hesitated a moment before obeying, drawing the silk up along her legs. She looked up to the buyer who watched her cooly, nodding a little "Keep going." He waited until the hem was at her waist before telling her to stop, then taking the little handbag he'd given her to accessorise the dress. She'd thought it was empty, and was surprised when he pulled a small box from it. Inside was a small silver egg. He picked it up, a wicked grin flickering over his features, and looked back to Anna. His hands went to her bare pussy, finding her already wet. He parted the folds of her labia and pressed the egg against her entrance, laughing softly as she tensed instinctively. The egg slipped in with only a little resistance, and she gasped as it did, clenching around it.
The buyer brought his fingers to her lips and she opened her mouth obediently, wrapping her tongue around his fingers without him needing to ask, cleaning her juices from his hand. Once that was done, he took out his phone and swiped a series of gestures across its face. The egg inside her pussy began to vibrate, and Anna gasped before she could think, taken by surprise.
"Perfect," the buyer murmured, then took her collar and pulled down sharply. "On your knees now." She sank quickly, looking up for only a moment before bringing her hands to his belt and freeing his cock, knowing instinctively this was what she was supposed to do. He took the collar in both hands and pushed her head against the wall before thrusting his cock into her open mouth. She cried out, the sound muffled on his cock, and wrapped her arms around him as much for balance as to pull him in, as it became clear quickly this would not be a finessed or high quality act, she wouldn't get to show off her skill. She was just there to be fucked.
The egg vibrated against the walls of her pussy as the buyer thrust deep into her throat, making her gag and choke and struggle for air. Every time he pinned her head to the wall he bled off a little more aggression into her until finally releasing his cum into her, nearly choking her as she struggled to swallow every drop. Almost immediately he reached for his phone and the toy inside her stopped moving. She whimpered as he pulled out of her mouth, and she sank against the wall once he was no longer holding her up.
"Fix your makeup," he ordered, pointing in the direction of a ladies' room. "We're not done yet for the night, and you need to be polished and back on my arm."
