Grandpa's cock throbs in his granddaughter's warm, wet mouth, her big tits pressing against his thighs. She's an amateur at pleasing him, but her enthusiasm more than makes up for it. She jerks him off, her hand working in sync with her mouth, until he's ready to burst. He cums hard, his load filling her mouth. She swallows greedily, her hands sticky with his cum, leaving her craving more.
