"Cum for me, David," purrs Gina, her Russian accent laced with dominance. She demonstrates her technique, her tongue flicking out to lick his length, her hand pumping in slow, deliberate strokes. David's body responds eagerly, his breath coming in ragged gasps. Gina's other hand cups his balls, her nails lightly scratching, adding to the exquisite torment. She teases him relentlessly, pulling back just as he's about to climax, her laughter husky and knowing. "Not yet, David," she whispers, her eyes gleaming with anticipation.
