In a cramped, dimly lit room, a nephew's desperate masturbation is interrupted by his aunt's sudden entrance. Embarrassed, he tries to hide his stiff cock, but she's intrigued. She tentatively touches it, then, driven by curiosity and lust, takes it in her mouth. He groans, grabbing her hair as she sucks, her inexperienced but eager tongue exploring his length. She climbs onto his lap, his cock pressing against her panties. She grinds on him, her breath hitching as she feels his hardness. She wants more, but a creaking floorboard stops them, leaving them both panting and needy.
