Frank wants your girlfriend

The air in the club is suffocating, the bass vibrating through your bones. Sara stands next to you, her fingers digging into your arm as she spots Frank at the bar – that massive guy with the confident grin and the cock that's impossible to miss even through his jeans. "Fuck, he's exactly my type," she whispers in your ear, her eyes glued to him. You feel her breathing quicken, how she unconsciously presses against you, as if testing you. "Come on," she hisses and pulls you along, straight toward Frank. His gaze slides over her body as if she's already his. "Well, sweetheart, finally got the courage?" his voice is deep, smoky. Sara bites her lip, her gaze flickering between you and him. "I want you to watch him take me," she suddenly says, while her fingers already graze Frank's arm. The door to the side room stands open. What now?
