Settling onto his lap, she begins to grind her hips, feeling the growing bulge in his pants. She unzips him, revealing his throbbing cock, and starts to stroke it gently, her hand slick with spit. She leans over, taking the head into her mouth, swirling her tongue around it. She picks up the pace, her head bobbing up and down, her hand working in tandem. She can feel him tense up, and he warns her, but she doesn't stop. He erupts in her mouth, and she swallows every drop, licking her lips clean.
