A curious 18-year-old, home alone and horny, answers a knock at the door. It's her dad's friend, a rugged, older man with a mischievous grin. She invites him in, her eyes lingering on his crotch. He notices her wandering gaze and smirks, "You're all grown up now, aren't you?" She blushes, but her curiosity piqued, she asks him to teach her a thing or two. He obliges, pushing her against the wall and grinding his hardness against her. She gasps, feeling his thickness through his jeans. He unzips, revealing his massive cock, and she tentatively wraps her small hand around it. He guides her, teaching her how to stroke him, and then, with a growl, pushes her to her knees, ready to give her first lesson in deepthroating.
