The room is filled with the scent of sex and the sound of their heavy breathing. She's on her knees, her ass in the air, her pussy dripping with anticipation. He stands behind her, his cock hard, throbbing. He grips her hips, pulling her back onto him, filling her with one swift thrust. She gasps, her fingers clutching the sheets. He sets a punishing pace, his hips slapping against her ass, his cock stretching her, filling her. She's close, her body tensing, her breath coming in short gasps. He leans over her, his hand wrapping around her throat, his voice a growl in her ear, 'You want it, don't you? You want me to fill you up.' She nods, her eyes closed, her body trembling as she comes, his hot semen pulsing into her, marking her, satisfying her craving.
