In a hidden corner of the house, the teen's grandpa finds her, eager to explore the taboo. She looks up at him, her big, innocent eyes filled with a newfound lust. He unzips his pants, revealing his massive, veiny cock. She gasps, then tentatively reaches out, wrapping her small hand around his shaft. He groans, guiding her head down as she tentatively takes him into her mouth. She struggles at first, but soon finds a rhythm, her head bobbing up and down as she eagerly sucks his old cock.
