In a hidden corner of the house, grandpa and the teen begin their forbidden affair, his thick, veiny cock throbbing with desire. She eagerly takes him in her mouth, gagging on his length, before he pulls out and pisses into her waiting, open mouth. She swallows every drop, tasting his salty essence, then returns to sucking him off, driving him to the edge before he explodes in her mouth, filling it with his hot, sticky cum.
